	LoongArch: Fix some test failures about TLS desc and TLS relaxation
	There are two issues causing 11 test failures:

	1. The TLS desc tests are matching the entire disassemble of a linked
	   executable.  But if ld is configured --enable-default-hash-style=gnu
	   (note that most modern distros use this option), the layout of the
	   linked executables will be different and the immediate operands in
	   the linked executables will also be different.  So we add
	   "--hash-style=both" for these tests to cancel the effect of
	   --enable-default-hash-style=gnu, like [x86_64 mark-plt tests].
	2. By default objdump disassemble uses [pseudo-instructions] so "addi.w"
	   is outputed as "li.w", causing mismatches in TLS relaxation tests.
	   We can turn off the pseudo-instruction usage in objdump using "-M
	   no-aliases" to fix them.

	x86/APX: VROUND{P,S}{S,D} can generally be encoded
	VRNDSCALE{P,S}{S,D} is the AVX512 generalization of these AVX insns. As
	long as the immediate has the top 4 bits clear, they are equivalent to
	the earlier VEX-encoded insns, and hence can be used to permit use of
	eGPR-s in the memory operand. Since this is the normal way of using
	these insns, also alter the resulting diagnostic to complain about the
	immediate, not the eGPR use.

	x86/APX: be consistent with insn suffixes
	When there's a suitably disambiguating register operand, suffixes are
	generally omitted (unless in suffix-always mode). All NDD insns have a
	suitable register operand, so they shouldn't have suffixes by default.

	instructions in Binutils.

	aarch64: rcpc3: add support in general_constraint_met_p
	Given the introduction of the new address operand types for rcpc3
	instructions, this patch adds the necessary logic to teach
	`general_constraint_met_p` how to proper handle these.

2024-01-15  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: rcpc3: New RCPC3_ADDR operand types
	The particular choices of address indexing, along with their encoding
	for RCPC3 instructions lead to the requirement of a new set of operand
	descriptions, along with the relevant inserter/extractor set.

	That is, for the integer load/stores, there is only a single valid
	indexing offset quantity and offset mode is allowed - The value is
	always equivalent to the amount of data read/stored by the
	operation and the offset is post-indexed for Load-Acquire RCpc, and
	pre-indexed with writeback for Store-Release insns.

	This indexing quantity/mode pair is selected by the setting of a
	single bit in the instruction. To represent these insns, we add the
	following operand types:

	  - AARCH64_OPND_RCPC3_ADDR_OPT_POSTIND
	  - AARCH64_OPND_RCPC3_ADDR_OPT_PREIND_WB

	In the case of loads and stores involving SIMD/FP registers, the
	optional offset is encoded as an 8-bit signed immediate, but neither
	post-indexing or pre-indexing with writeback is available.  This
	created the need for an operand type similar to
	AARCH64_OPND_ADDR_OFFSET, with the difference that FLD_index should
	not be checked.

	We thus introduce the AARCH64_OPND_RCPC3_ADDR_OFFSET operand, a
	variant of AARCH64_OPND_ADDR_OFFSET, w/o the FLD_index bitfield.

2024-01-15  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: rcpc3: Define address operand fields and inserter/extractors
	Beyond the need to encode any registers involved in data transfer and
	the address base register for load/stores, it is necessary to specify
	the data register addressing mode and whether the address register is
	to be pre/post-indexed, whereby loads may be post-indexed and stores
	pre-indexed with write-back.

	The use of a single bit to specify both the indexing mode and indexing
	value requires a novel function be written to accommodate this for
	address operand insertion in assembly and another for extraction in
	disassembly, along with the definition of two insn fields for use with
	these instructions.

	This therefore defines the following functions:

	  - aarch64_ins_rcpc3_addr_opt_offset
	  - aarch64_ins_rcpc3_addr_offset
	  - aarch64_ext_rcpc3_addr_opt_offset
	  - aarch64_ext_rcpc3_addr_offset

	It extends the `do_special_{encoding|decoding}' functions and defines
	two rcpc3 instruction fields:

	  - FLD_opc2
	  - FLD_rcpc3_size

2024-01-15  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: rcpc3: Create implicit load/store size calc function
	The allowed immediate offsets in integer rcpc3 load store instructions
	are not encoded explicitly in the instruction itself, being rather
	implicitly equivalent to the amount of data loaded/stored by the
	instruction.

	This leads to the requirement that this quantity be calculated based on
	the number of registers involved in the transfer, either as data
	source or destination registers and their respective qualifiers.

	This is done via `calc_ldst_datasize (const aarch64_opnd_info *opnds)'
	implemented here, using a cumulative sum of qualifier sizes preceding
	the address operand in the OPNDS operand list argument.

	gas/NEWS: announce the new SCFI command line option

2024-01-15  Indu Bhagat  <indu.bhagat@oracle.com>

	gas: testsuite: add an x86 testsuite for SCFI
	The testsuite for SCFI contains target-specific tests.

	When a test is executed with --scfi=experimental command line option,
	the CFI annotations in the test .s files are skipped altogether by the
	GAS for processing.  The CFI directives in the input assembly files are,
	however, validated by running the assembler one more time without
	--scfi=experimental.

	Some testcases are used to highlight those asm constructs that the SCFI
	machinery in GAS currently does not support:

	  - Only System V AMD64 ABI is supported for now. Using either --32 or
	    --x32 with SCFI results in hard error.
	    See scfi-unsupported-1.s.

	  - Untraceable stack-pointer manipulation in function epilougue and prologue.
	    See scfi-unsupported-2.s.

	  - Using Dynamically Realigned Arguement Pointer (DRAP) register to
	    realign the stack.  For SCFI, the CFA must be only REG_SP or REG_FP
	    based.  See scfi-unsupported-drap-1.s

	Some testcases are used to highlight some diagnostics that the SCFI
	machinery in GAS currently issues, with an intent to help user correct
	inadvertent errors in their hand-written asm.  An error is issued when
	GAS finds that input asm is not amenable to correct CFI synthesis.

	  - (#1) "Warning: SCFI: Asymetrical register restore"
	  - (#2) "Error: SCFI: usage of REG_FP as scratch not supported"
	  - (#3) "Error: SCFI: unsupported stack manipulation pattern"

	In case of (#2) and (#3), SCFI generation is skipped for the respective
	function.  Above is a subset of the warnings/errors implemented in the
	code.

	gas: x86: synthesize CFI for hand-written asm
	This patch adds support in GAS to create generic GAS instructions
	(a.k.a., the ginsn) for the x86 backend (AMD64 ABI only at this time).
	Using this ginsn infrastructure, GAS can then synthesize CFI for
	hand-written asm for x86_64.

	A ginsn is a target-independent representation of the machine
	instructions.  One machine instruction may need one or more ginsn.

	This patch also adds skeleton support for printing ginsn in the listing
	output for debugging purposes.

	Since the current use-case of ginsn is to synthesize CFI, the x86 target
	needs to generate ginsns necessary for the following machine
	instructions only:

	 - All change of flow instructions, including all conditional and
	   unconditional branches, call and return from functions.
	 - All register saves and unsaves to the stack.
	 - All instructions affecting the two registers that could potentially
	   be used as the base register for CFA tracking.  For SCFI, the base
	   register for CFA tracking is limited to REG_SP and REG_FP only for
	   now.

	The representation of ginsn is kept simple:

	- GAS instruction has GINSN_NUM_SRC_OPNDS (defined to be 2 at this time)
	  number of source operands and one destination operand at this time.
	- GAS instruction uses DWARF register numbers in its representation and
	  does not track register size.
	- GAS instructions carry location information (file name and line
	  number).
	- GAS instructions are ID's with a natural number in order of their
	  addtion to the list.  This can be used as a proxy for the static
	  program order of the corresponding machine instructions.

	Note that, GAS instruction (ginsn) format does not support
	GINSN_TYPE_PUSH and GINSN_TYPE_POP.  Some architectures, like aarch64,
	do not have push and pop instructions, but rather STP/LDP/STR/LDR etc.
	instructions.  Further these instructions have a variety of addressing
	modes, like offset, pre-indexing and post-indexing etc.  Among other
	things, one of differences in these addressing modes is _when_ the addr
	register is updated with the result of the address calculation: before
	or after the memory operation.  To best support such needs, the generic
	instructions like GINSN_TYPE_LOAD, GINSN_TYPE_STORE together with
	GINSN_TYPE_ADD, and GINSN_TYPE_SUB may be used.

	The functionality provided in ginsn.c and scfi.c is compiled in when a
	target defines TARGET_USE_SCFI and TARGET_USE_GINSN.  This can be
	revisited later when there are other use-cases of creating ginsn's in
	GAS, apart from the current use-case of synthesizing CFI for
	hand-written asm.

	Support is added only for System V AMD64 ABI for ELF at this time.  If
	the user enables SCFI with --32, GAS issues an error:

	  "Fatal error: SCFI is not supported for this ABI"

	For synthesizing (DWARF) CFI, the SCFI machinery requires the programmer
	to adhere to some pre-requisites for their asm:
	   - Hand-written asm block must begin with a .type   foo, @function
	It is highly recommended to, additionally, also ensure that:
	   - Hand-written asm block ends with a .size foo, .-foo

	The SCFI machinery encodes some rules which align with the standard
	calling convention specified by the ABI.  Apart from the rules, the SCFI
	machinery employs some heuristics.  For example:
	   - The base register for CFA tracking may be either REG_SP or REG_FP.
	   - If the base register for CFA tracking is REG_SP, the precise amount of
	     stack usage (and hence, the value of REG_SP) must be known at all times.
	   - If using dynamic stack allocation, the function must switch to
	     FP-based CFA.  This means using instructions like the following (in
	     AMD64) in prologue:
	        pushq   %rbp
	        movq    %rsp, %rbp
	     and analogous instructions in epilogue.
	   - Save and Restore of callee-saved registers must be symmetrical.
	     However, the SCFI machinery at this time only warns if any such
	     asymmetry is seen.

	These heuristics/rules are architecture-independent and are meant to
	employed for all architectures/ABIs using SCFI in the future.

	Rex2 is currently an operand constraint.  For the upcoming SCFI
	implementation in GAS, we need to identify operations which implicitly
	update the stack pointer.  An operand constraint enumerator for implicit
	stack op seems more appropriate than an attribute.  However, two opcodes

	gas: add new command line option --scfi=experimental
	When the command line option --scfi=experimenta is passed to the GNU
	assembler, it will synthesize DWARF call frame information (CFI) for the
	input assembly.

	The option --scfi=experimental will also ignore most of the existing
	.cfi_* directives, if already contained in the provided input file.
	Only the following CFI directives will not be ignored:
	  - .cfi_sections,
	  - .cfi_label,
	  - .cfi_signal_frame

	To use SCFI, a target will need to:
	    - define TARGET_USE_SCFI and TARGET_USE_GINSN, and other necessary
	    definitions,
	    - provide means to help GAS understand the target specific instruction
	    semantics by creating ginsns.

	The upcoming support for SCFI is inteded to be experimental, hence the
	option --scfi=experimental.  The --scfi= may see more options like
	--scfi=[all,none] added in future, once the SCFI support in GAS is
	mature and robust.  The offering may also see for example, an
	--scfi=inline option for dealing with inline asm may be added in the
	future.  In --scfi=inline option, the GNU assembler may consume (and not
	ignore) the compiler generated CFI for the code surrounding the inline
	asm.

	[gdb/testsuite] Fix gdb.mi/mi-dprintf.exp with read1

	which uses a gdb_test_multiple that is supposed to use the mi prompt, but
	doesn't use -prompt to indicate this.  Consequently, the default patterns use

	which use "$::mi_gdb_prompt$".

	Fix this by adding the missing -prompt "$::mi_gdb_prompt$" arguments.

	While we're at it, make the gdb_test_multiple call a bit more readable by
	using variables, and by using -wrap.

	gdb/testsuite: fix failure in gdb.python/py-inferior.exp
	After this commit:

	  commit 1925bba80edd37c2ef90ef1d2c599dfc2fc17f72
	  Date:   Thu Jan 4 10:01:24 2024 +0000

	      gdb/python: add gdb.InferiorThread.__repr__() method

	failures were reported for gdb.python/py-inferior.exp.

	The test grabs a gdb.InferiorThread object representing an inferior
	thread, and then, later in the test, expects this Python object to
	become invalid when the inferior thread has exited.

	The gdb.InferiorThread object was obtained from the list returned by
	calling gdb.Inferior.threads().

	The mistake I made in the original commit was to assume that the order
	of the threads returned from gdb.Inferior.threads() somehow reflected
	the thread creation order.  Specifically, I was expecting the main
	thread to be first in the list, and "other" threads to appear ... not
	first.

	However, the gdb.Inferior.threads() function creates a list and
	populates it from a map.  The order of the threads in the returned
	list has no obvious relationship to the thread creation order, and can
	vary from host to host.

	On my machine the ordering was as I expected, so the test passed for
	me.  For others the ordering was not as expected, and it just happened
	that we ended up recording the gdb.InferiorThread for the main thread.

	As the main thread doesn't exit (until the test is over), the
	gdb.InferiorThread object never became invalid, and the test failed.

	Fixed in this commit by taking more care to correctly find a non-main
	thread.  I do this by recording the main thread early on (when there
	is only one inferior thread), and then finding any thread that is not
	this main thread.

	Then, once all of the secondary threads have exited, I know that the
	second InferiorThread object I found should now be invalid.

	The test still passes for me, and I believe this should fix the issue
	for everyone else too.

	gdb/doc: add some notes on selecting suitable attribute names
	In previous commits I've added Object.__dict__ support to gdb.Inferior
	and gdb.InferiorThread, this is similar to the existing support for
	gdb.Objfile and gdb.Progspace.

	This commit extends the documentation to offer the user some guidance
	on selecting good names for their custom attributes so they
	can (hopefully) avoid conflicting with any future attributes that GDB
	might add.

	The rules I've proposed are:

	  1. Don't start user attributes with a lower case letter, all the
	  current GDB attributes start with a lower case letter, and I suspect
	  all future attributes would also start with a lower case letter, and

	  2. Don't start user attributes with a double underscore, this risks
	  conflicting with Python built in attributes (e.g. __dict__) - though
	  clearly the user would need to start and end with a double
	  underscore, but it seemed easier just to say no double underscores.

	I'm doing this as a separate commit as I've updated the docs for the
	existing gdb.Objfile and gdb.Progspace so they all reference a single
	paragraph on selecting attribute names.

	gdb/python: remove users ability to create gdb.Progspace objects
	I noticed that it is possible for the user to create a new
	gdb.Progspace object, like this:

	  (gdb) pi
	  >>> p = gdb.Progspace()
	  >>> p
	  <gdb.Progspace object at 0x7ffad4219c10>
	  >>> p.is_valid()
	  False

	As the new gdb.Progspace object is not associated with an actual C++
	program_space object within GDB core, then the new gdb.Progspace is
	created invalid, and there is no way in which the new object can ever
	become valid.

	Nor do I believe there's anywhere in the Python API where it makes
	sense to consume an invalid gdb.Progspace created in this way, for
	example, the gdb.Progspace could be passed as the locus to
	register_type_printer, but all that would happen is that the
	registered printer would never be used.

	In this commit I propose to remove the ability to create new
	gdb.Progspace objects.  Attempting to do so now gives an error, like
	this:

	  (gdb) pi
	  >>> gdb.Progspace()
	  Traceback (most recent call last):
	    File "<stdin>", line 1, in <module>
	  TypeError: cannot create 'gdb.Progspace' instances

	Of course, there is a small risk here that some existing user code
	might break ... but if that happens I don't believe the user code can
	have been doing anything useful, so I see this as a small risk.

	gdb/python: hoist common invalid object repr code into py-utils.c
	Many object types now have a __repr__() function implementation.  A
	common pattern is that, if an object is invalid, we print its
	representation as: <TYPENAME (invalid)>.

	I thought it might be a good idea to move the formatting of this
	specific representation into a utility function, and then update all
	of our existing code to call the new function.

	The only place where I haven't made use of the new function is in
	unwind_infopy_repr, where we currently return a different string.
	This case is a little different as the UnwindInfo is invalid because
	it references a frame, and it is the frame itself which is invalid.
	That said, I think it would be fine to switch to using the standard
	format; if the UnwindInfo references an invalid frame, then the
	UnwindInfo is itself invalid.  But changing this would be an actual
	change in behaviour, while all the other changes in this commit are
	just refactoring.

	gdb: add trailing '/' when using 'complete' with directory names
	This patch contains work pulled from this previously proposed patch:

	  https://inbox.sourceware.org/gdb-patches/20210213220752.32581-2-lsix@lancelotsix.com/

	But has been modified by me.  Credit for the original idea and
	implementation goes to Lancelot, any bugs in this new iteration belong
	to me.

	Consider the executable `/tmp/foo/my_exec', and if we assume `/tmp' is
	empty other than the `foo' sub-directory, then currently within GDB,
	if I type:

	  (gdb) file /tmp/f

	and then hit TAB, GDB completes this to:

	  (gdb) file /tmp/foo/

	notice that not only did GDB fill in the whole of `foo', but GDB also
	added a trailing '/' character.  This is done within readline when the
	path that was just completed is a directory.  However, if I instead
	do:

	  (gdb) complete file /tmp/f
	  file /tmp/foo

	I now see the completed directory name, but the trailing '/' is
	missing.  The reason is that, in this case, the completions are not
	offered via readline, but are handled entirely within GDB, and so
	readline never gets the chance to add the trailing '/' character.

	The above patch added filename option support to GDB, which included
	completion of the filename options.  This initially suffered from the
	same problem that I've outlined above, but the above patch proposed a
	solution to this problem, but this solution only applied to filename
	options (which have still not been added to GDB), and was mixed in
	with the complete filename options support.

	This patch pulls out just the fix for the trailing "/" problem, and
	applies it to GDB's general filename completion.  This patch does not
	add filename options to GDB, that can always be done later, but I
	think this small part is itself a useful fix.

	One of the biggest changes I made in this version is that I got rid of
	the set_from_readline member function, instead, I now pass the value
	of m_from_readline into the completion_tracker constructor.

	I then moved the addition of the trailing '/' into filename_completer
	so that it is applied in the general filename completion case.  I also
	added a call to gdb_tilde_expand which was missing from the original
	patch, I haven't tested, but I suspect that this meant that the
	original patch would not add the trailing '/' if the user entered a
	path starting with a tilde character.

	When writing the test for this patch I ran into two problems.

	The first was that the procedures in lib/completion-support.exp relied
	on the command being completed for the test name.  This is fine for
	many commands, but not when completing a filename, if we use the
	command in this case the test name will (potentially) include the name
	of the directory in which the test is being run, which means we can't
	compare results between two runs of GDB from different directories.

	So in this commit I've gone through completion-support.exp and added a
	new (optional) testname argument to many of the procedures, this
	allows me to give a unique test name, that doesn't include the path
	for my new tests.

	The second issue was in the procedure make_tab_completion_list_re,
	this builds the completion list which is displayed after a double tab
	when there are multiple possible completions.

	The procedure added the regexp ' +' after each completion, and then
	added another ' +' at the very end of the expected output.  So, if we
	expected to match the name of two functions 'f1' and 'f2' the
	generated regexp would be: 'f1 +f2 + +'.  This would match just fine,
	the actual output would be: 'f1  f2  ', notice that we get two spaces
	after each function name.

	However, if we complete two directory names 'd1' and 'd2' then the
	output will be 'd1/ d2/ '.  Notice that now we only have a single
	space between each match, however, we do get the '/' added instead.

	What happens is that when presenting the matches, readline always adds
	the appropriate trailing character; if we performed tab completion of
	'break f1' then, as 'f1' is a unique match, we'd get 'break f1 ' with
	a trailing space added.  However, if we complete 'file d1' then we get
	'file d1/'.  Then readline is adding a single space after each

	gdb/python: New InferiorThread.ptid_string attribute
	This commit adds a new InferiorThread.ptid_string attribute.  This
	read-only attribute contains the string returned by target_pid_to_str,
	which actually converts a ptid (not pid) to a string.

	This is the string that appears (at least in part) in the output of
	'info threads' in the 'Target Id' column, but also in the thread
	exited message that GDB prints.

	Having access to this string from Python is useful for allowing
	extensions identify threads in a similar way to how GDB core would
	identify the thread.

	gdb: fix frame passed to gdbarch_value_to_register in value_assign
	Commit 78f2fd84e83 ("gdb: remove VALUE_REGNUM, add value::regnum")
	introduced an unexpected change in value_assign.  It replaced
	`get_prev_frame_always (next_frame)` with `next_frame`in the call to
	gdbarch_value_to_register.

	This is the result of a merge error, since I previously had a patch to
	change gdbarch_value_to_register to take the next frame, and later
	decided to drop it.  Revert that change.

	Add a test based on the DWARF assembler to expose the problem and test
	the fix.  I also tested on ppc64le to make sure the problem reported in
	PR 31231 was fixed.

	The test-case attemps to emulate additional entry points of a function, with

	...

	However, when setting a breakpoint on the entry point foo:
	...
	(gdb) b foo
	Breakpoint 1 at 0x100006dc
	...
	it ends up in foobar instead of in foo, due to prologue skipping, and
	consequently the backtrace show foobar instead foo.

	The problem is that the test-case does not emulate an actual prologue at each
	entry point.

	Fix this by disabling the prologue skipping when setting a breakpoint, using
	"break *foo".

	[gdb/testsuite] Extend gdb.base/kill-during-detach.exp
	I ran into the following FAIL:

	(gdb) FAIL: gdb.base/kill-during-detach.exp: exit_p=true: checkpoint_p=true: \
	  python kill_and_detach()
	...

	The FAIL happens as follows:
	- gdb is debugging a process A
	- a checkpoint is created, in other words, fork is called in the inferior,
	  after which we have:
	  - checkpoint 0 (the fork parent, process A), and
	  - checkpoint 1 (the fork child, process B).
	- during checkpoint creation, lseek is called in the inferior (process A) for
	  all file descriptors, and it returns != -1 for at least one file descriptor.
	- the process A continues in the background
	- gdb detaches, from process A
	- gdb switches to process B, in other words, it restarts checkpoint 1
	- while restarting checkpoint 1, gdb tries to call lseek in the inferior
	  (process B), but this fails because gdb incorrectly thinks that inferior B
	  is running.

	This happens because linux_nat_switch_fork patches the pid of process B into
	the current inferior and current thread which where originally representing
	process A.  So, because process A was running in the background, the
	thread_info fields executing and resumed are set accordingly, but they are not
	correct for process B.

	There's a line in fork_load_infrun_state that fixes up the thread_info field
	stop_pc, so fix this by adding similar fixups for the executing and resumed
	fields alongside.

	The FAIL did not always reproduce, so extend the test-case to reliably
	trigger this scenario.

	Tested on x86_64-linux.

	Clean up some of the functions where possible to avoid unnecessary

	if Linux/glibc & m32r had defined behavior, those aren't the host for
	the sim runtime.

	So let's stop using the function and switch to clock_gettime.  gnulib

	    Config,Darwin: Allow for configuring Darwin to use embedded runpath.

	    Recent Darwin versions place contraints on the use of run paths
	    specified in environment variables.  This breaks some assumptions
	    in the GCC build.

	    This change allows the user to configure a Darwin build to use
	    '@rpath/libraryname.dylib' in library names and then to add an
	    embedded runpath to executables (and libraries with dependents).

	    The embedded runpath is added by default unless the user adds
	    '-nodefaultrpaths' to the link line.

	    For an installed compiler, it means that any executable built with
	    that compiler will reference the runtimes installed with the
	    compiler (equivalent to hard-coding the library path into the name
	    of the library).

	    During build-time configurations  any "-B" entries will be added to
	    the runpath thus the newly-built libraries will be found by exes.

	    Since the install name is set in libtool, that decision needs to be
	    available here (but might also cause dependent ones in Makefiles,
	    so we need to export a conditional).

	    This facility is not available for Darwin 8 or earlier, however the
	    existing environment variable runpath does work there.

	    We default this on for systems where the external DYLD_LIBRARY_PATH
	    does not work and off for Darwin 8 or earlier.  For systems that can
	    use either method, if the value is unset, we use the default (which
	    is currently DYLD_LIBRARY_PATH).

	gdb/symtab: Eliminate deferred_entry
	Currently cooked_index entry creation is either:

	- deferred if the parent_entry is not yet known, and done later while

	Instead, create all cooked_index entries immediately, and keep track of which

	    libiberty: Fix build with GCC < 7

	    Tobias reported on IRC that the linker fails to build with GCC 4.8.5.
	    In configure I've tried to use everything actually used in the sha1.c
	    x86 hw implementation, but unfortunately I forgot about implicit function
	    declarations.  GCC before 7 did have <cpuid.h> header and bit_SHA define
	    and __get_cpuid function defined inline, but it didn't define
	    __get_cpuid_count, which compiled fine (and the configure test is
	    intentionally compile time only) due to implicit function declaration,
	    but then failed to link when linking the linker, because
	    __get_cpuid_count wasn't defined anywhere.

	    The following patch fixes that by using what autoconf uses in AC_CHECK_DECL
	    to make sure the functions are declared.

	    c++: mangle function template constraints

	    Per https://github.com/itanium-cxx-abi/cxx-abi/issues/24 and
	    https://github.com/itanium-cxx-abi/cxx-abi/pull/166

	    We need to mangle constraints to be able to distinguish between function
	    templates that only differ in constraints.  From the latter link, we want to
	    use the template parameter mangling previously specified for lambdas to also
	    make explicit the form of a template parameter where the argument is not a
	    "natural" fit for it, such as when the parameter is constrained or deduced.

	    I'm concerned about how the latter link changes the mangling for some C++98
	    and C++11 patterns, so I've limited template_parm_natural_p to avoid two
	    cases found by running the testsuite with -Wabi forced on:

	    template <class T, T V> T f() { return V; }
	    int main() { return f<int,42>(); }

	    template <int i> int max() { return i; }
	    template <int i, int j, int... rest> int max()
	    {
	      int sub = max<j, rest...>();
	      return i > sub ? i : sub;
	    }
	    int main() {  return max<1,2,3>(); }

	    A third C++11 pattern is changed by this patch:

	    template <template <typename...> class TT, typename... Ts> TT<Ts...> f();
	    template <typename> struct A { };
	    int main() { f<A,int>(); }

	    I aim to resolve these with the ABI committee before GCC 14.1.

	    We also need to resolve https://github.com/itanium-cxx-abi/cxx-abi/issues/38
	    (mangling references to dependent template-ids where the name is fully
	    resolved) as references to concepts in std:: will consistently run into this
	    area.  This is why mangle-concepts1.C only refers to concepts in the global
	    namespace so far.

	    The library changes are to avoid trying to mangle builtins, which fails.

	    Demangler support and test coverage is not complete yet.

	    As is already done in a couple of other similar cases, this patches

	    [PATCH v3] libiberty: Use posix_spawn in pex-unix when available.

	    Hi,

	    This patch implements pex_unix_exec_child using posix_spawn when
	    available.

	    This should especially benefit recent macOS (where vfork just calls
	    fork), but should have equivalent or faster performance on all
	    platforms.
	    In addition, the implementation is substantially simpler than the
	    vfork+exec code path.

	    Tested on x86_64-linux.

	    v2: Fix error handling (previously the function would be run twice in
	    case of error), and don't use a macro that changes control flow.

	    v3: Match file style for error-handling blocks, don't close
	    in/out/errdes on error, and check close() for errors.

	    c++: constrained hidden friends [PR109751]

	    r13-4035 avoided a problem with overloading of constrained hidden friends by
	    checking satisfaction, but checking satisfaction early is inconsistent with
	    the usual late checking and can lead to hard errors, so let's not do that
	    after all.

	    We were wrongly treating the different instantiations of the same friend
	    template as the same function because maybe_substitute_reqs_for was failing
	    to actually substitute in the case of a non-template friend.  But we don't
	    actually need to do the substitution anyway, because [temp.friend] says that
	    such a friend can't be the same as any other declaration.

	    After fixing that, instead of a redefinition error we got an ambiguous
	    overload error, fixed by allowing constrained hidden friends to coexist
	    until overload resolution, at which point they probably won't be in the same
	    ADL overload set anyway.

	    And we avoid mangling collisions by following the proposed mangling for
	    these friends as a member function with an extra 'F' before the name.  I
	    demangle this by just adding [friend] to the name of the function because
	    it's not feasible to reconstruct the actual scope of the function since the
	    mangling ABI doesn't distinguish between class and namespace scopes.

	aarch64: Regenerate aarch64-*-2.c files

2024-01-09  Victor Do Nascimento  <victor.donascimento@arm.com>

	arch64: Add optional operand register pair support tests
	Add tests to cover the full range of behaviors observed around
	optional register operands for the `tlbip' and `sysp' instructions,
	namely:

	  * Not all `tlbip' operations take GPR operands.  When this is the
	  case, we should check that neither optional operand was supplied.
	  * When a `tlbip' operation is labeled with the `F_HASXT' flag, xzr
	  is not a valid optional operand.  In such case, at least the fist
	  optional register needs to be specified with a non-xzr value.
	  * The first operand for both insns should be either xzr or an
	  even-numbered register (n % 2 == 0).  In the former scenario, the
	  second operand should default to xzr too, while in the latter, it
	  should default to n + 1.

2024-01-09  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: Add support for 128-bit system register mrrs and msrr insns
	With the addition of 128-bit system registers to the Arm architecture
	starting with Armv9.4-a, a mechanism for manipulating their contents
	is introduced with the `msrr' and `mrrs' instruction pair.

	These move values from one such 128-bit system register into a pair of
	contiguous general-purpose registers and vice-versa, as for example:

		   msrr ttlb0_el1, x0, x1
		   mrrs x0, x1, ttlb0_el1

	This patch adds the necessary support for these instructions, adding
	checks for system-register width by defining a new operand type in the
	form of `AARCH64_OPND_SYSREG128' and the `aarch64_sys_reg_128bit_p'
	predicate, responsible for checking whether the requested system
	register table entry is marked as implemented in the 128-bit mode via
	the F_REG_128 flag.

	aarch64: Add TLBIP tests

2024-01-09  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: Add xs variants of tlbip operands
	The 2020 Architecture Extensions to the Arm A-profile architecture
	added FEAT_XS, the XS attribute feature, giving cores the ability to
	identify devices which can be subject to long response delays. TLB
	invalidate (TLBI) operations and barriers can also be annotated with
	this attribute[1].

	With the introduction of the 128-bit translation tables with the
	Armv8.9-a/Armv9.4-a Translation Hardening Extension, a series of new
	TLB invalidate operations are introduced which make use of this
	extension.  These are added to aarch64_sys_regs_tlbi[] for use
	with the `tlbip' insn.

	aarch64: Implement TLBIP 128-bit instruction
	The addition of 128-bit page table descriptors and, with it, the
	addition of 128-bit system registers for these means that special
	"invalidate translation table entry" instructions are needed to cope
	with the new 128-bit model.  This is introduced with the `tlbpi'
	instruction, implemented here.

2024-01-09  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: Create QL_SRC_X2 and QL_DEST_X2 qualifier macros
	Some 128-bit system operations (mrrs, msrr, tlbip, and sysp) take two
	qualified operands and one of unqualified type (e.g. system register
	name, tlbip operation).  This creates the need for adequate qualifiers
	to handle this.

	This patch therefore introduces the `QL_SRC_X2' and `QL_DST_X2' qualifier
	specifiers, which expand to `QLF3(NIL,X,X)' and `QLF3(X,X,NIL)',
	respectively.

2024-01-09  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: Apply narrowing of allowed immediate values for SYSP
	While CRn and CRm fields in the SYSP instruction are 4-bit wide and
	are thus able to accommodate values in the range 0-15, the
	specifications for the SYSP instructions limit their ranges to 8-9 for
	CRm and 0-7 in the case of CRn.

	This led to the need to signal in some way to the operand parser that
	a given operand is under special restrictions regarding its use.  This
	is done via the new `F_OPD_NARROW' flag, indicating a narrowing in the
	range of operand values for fields in the instruction tagged with the
	flag.

	The flag is then used in `parse_operands' when the instruction is
	assembled, but needs not be taken into consideration during
	disassembly.

2024-01-09  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: Add support for the SYSP 128-bit system instruction
	Mirroring the use of the `sys' - System Instruction assembly
	instruction, this implements its 128-bit counterpart, `sysp'.

	This optionally takes two contiguous general-purpose registers
	starting at an even number or, when these are omitted, by default
	sets both of these to xzr.

	Syntax:

		sysp #<op1>, <Cn>, <Cm>, #<op2>{, <Xt1>, <Xt2>}

2024-01-09  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: Add support for optional operand pairs
	Two of the instructions added by the `+d128' architectural extension
	add the flexibility to have two optional operands.  Prior to the
	addition of the `tlbip' and `sysp' instructions, no mnemonic allowed
	more than one such optional operand.

	With `tlbip' as an example, some TLBIP instruction names do not allow
	for any optional operands, while others allow for both to be optional.
	In the latter case, it is possible that either the second operand
	alone is omitted or both operands are omitted.
	Therefore, a considerable degree of flexibility needed to be added to
	the way operands were parsed.  It was, however, possible to achieve
	this with relatively few changes to existing code.

	it is noteworthy that opcode flags specifying the optional operand
	number are non-orthogonal. For example, we have:

	       #define F_OPD1_OPT (2 << 12) : 0b10 << 12
	       #define F_OPD2_OPT (3 << 12) : 0b11 << 12

	such that by virtue of the observation that

	       (F_OPD1_OPT | F_OPD2_OPT) == F_OPD2_OPT

	it is impossible to mark both operands 1 and 2 as optional for an
	instruction and it is assumed that a maximum of 1 operand can ever be
	optional.  This is not overly-problematic given that, for optional
	pairs, the second optional operand is always found immediately after
	the first.  Thus, it suffices for us to flag that there is a second
	optional operand.  With this fact, we can infer its position in the
	mnemonic from the position of the first (e.g. if the second operand in
	the mnemonic is optional, we know the third is too).  We therefore
	define the `F_OPD_PAIR_OPT' flag and calculate its position in the
	mnemonic from the value encoded by the `F_OPD<n>_OPT' flag.

	Another observation is that there is a tight coupling between default
	values assigned to the two registers when one (or both) are omitted
	from the mnemonic.  Namely, if Xt1 has a value of 0x1f (the zero
	register is specified), Xt2 defaults to the same value, otherwise Xt2
	will be assigned Xt + 1.  This meant that where you have default value
	validation, in checking the second optional operand's value, it is
	also necessary to look at the value assigned to the
	previously-processed operand value before deciding its validity. Thus
	`process_omitted_operand' needs not only access to its `operand'
	argument, but also to the global `inst' struct.

2024-01-09  Victor Do Nascimento  <victor.donascimento@arm.com>

	aarch64: Add support for xzr register in register pair operands
	Analysis of the allowed operand values for `sysp' and `tlbip' reveals
	a significant departure from the allowed behavior for operand register
	pairs (hitherto labeled AARCH64_OPND_PAIRREG) observed for other
	insns in this category.

	For instructions `casp', `mrrs' and `msrr' the register pair must
	always start at an even index and the second register in the pair is
	the index + 1.  This precludes the use of xzr as the first register,
	given it corresponds to register number 31.

	This is different in the case of `sysp' and `tlbip', however.  These
	allow the use of xzr and, where the first operand in the pair is
	omitted, this is the default value assigned to it.  When this
	operand is assigned xzr, it is expected that the second operand will
	likewise take on a value of xzr.

	These two instructions therefore "break" two rules of register pairs:

	  * The first of the two registers is odd-numbered.
	  * The index of the second register is equal to that of the first,
	  and not n+1.

	To allow for this departure from hitherto standard behavior, we
	extend the functionality of the assembler by defining an extension of
	the AARCH64_OPND_PAIRREG, called AARCH64_OPND_PAIRREG_OR_XZR.

	It is used in defining `sysp' and `tlbip' and allows
	`operand_general_constraint_met_p' to allow the pair to both take on
	the value of xzr.

	Given the introduction of the new Armv9.4-a `sysp' insn using the

		sysp #<op1>, <Cn>, <Cm>, #<op2>{, <Xt1>, <Xt2>}

	and by extension the need to encode 6 assembly operands, extend
	Binutils to handle instructions taking 6 operands, up from a previous
	maximum of 5.

	Back out some parallel_for_each features
	Now that the DWARF reader does not use parallel_for_each, we can
	remove some of the features that were added just for it: return values
	and task sizing.

	The thread_pool typed tasks feature could also be removed, but I
	haven't done so here.  This one seemed less intrusive and perhaps more
	likely to be needed at some point.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Avoid language-based lookups in startup path
	The previous patches are nearly enough to enable background DWARF
	reading.  However, this hack in language_defn::get_symbol_name_matcher
	causes an early computation of current_language:

	  /* If currently in Ada mode, and the lookup name is wrapped in
	     '<...>', hijack all symbol name comparisons using the Ada
	     matcher, which handles the verbatim matching.  */
	  if (current_language->la_language == language_ada
	      && lookup_name.ada ().verbatim_p ())
	    return current_language->get_symbol_name_matcher_inner (lookup_name);

	I considered various options here -- reversing the order of the
	checks, or promoting the verbatim mode to not be a purely Ada feature
	-- but in the end found that the few calls to this during startup
	could be handled more directly.

	In the JIT code, and in create_exception_master_breakpoint_hook, gdb
	is really looking for a certain kind of symbol (text or data) using a
	linkage name.  Changing the lookup here is clearer and probably more
	efficient as well.

	In create_std_terminate_master_breakpoint, the lookup can't really be
	done by linkage name (it would require relying on a certain mangling
	scheme, and also may trip over versioned symbols) -- but we know that
	this spot is C++-specific, and so the language ought to be temporarily
	set to C++ here.

	After this patch, the "file" case is much faster:

	    (gdb) file /tmp/gdb
	    2023-10-23 13:16:54.456 - command started
	    Reading symbols from /tmp/gdb...
	    2023-10-23 13:16:54.520 - command finished

	Optimize lookup_minimal_symbol_text
	lookup_minimal_symbol_text always loops over all objfiles, even when
	an objfile is passed in as an argument.  This patch changes the
	function to loop over the minimal number of objfiles in the latter
	situation.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Lazy language setting
	When gdb starts up with a symbol file, it uses the program's "main" to
	decide the "static context" and the initial language.  With background
	DWARF reading, this means that gdb has to wait for a significant
	amount of DWARF to be read synchronously.

	This patch introduces lazy language setting.  The idea here is that in
	many cases, the prompt can show up early, making gdb feel more
	responsive.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Change current_language to be a macro
	This changes the 'current_language' global to be a macro that wraps a

	language setting.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Remove two quick_symbol_functions methods
	quick_symbol_functions::read_partial_symbols is no longer implemented,
	so both it and quick_symbol_functions::can_lazily_read_symbols can be
	removed.  This allows for other functions to be removed as well.

	Note that SYMFILE_NO_READ is now pretty much dead.  I haven't removed
	it here -- but could if that's desirable.  I tend to think that this
	functionality would be better implemented in the core; but whenever I
	dive into the non-DWARF readers it is pretty depressing.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Simplify the public DWARF API
	dwarf2_has_info and dwarf2_initialize_objfile are only separate
	because the DWARF reader implemented lazy psymtab reading.  However,
	now that this is gone, we can simplify the public DWARF API again.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Do more DWARF reading in the background
	This patch rearranges the DWARF reader so that more work is done in
	the background.  This is PR symtab/29942.

	The idea here is that there is only a small amount of work that must
	be done on the main thread when scanning DWARF -- before the main
	scan, the only part is mapping the section data.

	Currently, the DWARF reader uses the quick_symbol_functions "lazy"
	functionality to defer even starting to read.  This patch instead
	changes the reader to start reading immediately, but doing more in
	worker tasks.

	Before this patch, "file" on my machine:

	    (gdb) file /tmp/gdb
	    2023-10-23 12:29:56.885 - command started
	    Reading symbols from /tmp/gdb...
	    2023-10-23 12:29:58.047 - command finished
	    Command execution time: 5.867228 (cpu), 1.162444 (wall)

	After the patch, more work is done in the background and so this takes
	a bit less time:

	    (gdb) file /tmp/gdb
	    2023-10-23 13:25:51.391 - command started
	    Reading symbols from /tmp/gdb...
	    2023-10-23 13:25:51.712 - command finished
	    Command execution time: 1.894500 (cpu), 0.320306 (wall)

	I think this could be further sped up by using the shared library load
	map to avoid objfile loops like the one in expand_symtab_containing_pc
	-- it seems like the correct objfile could be chosen more directly.

	Add deferred_warnings parameter to read_addrmap_from_aranges
	When DWARF reading is done in the background,
	read_addrmap_from_aranges will be called from a worker thread.
	Because warnings can't be emitted from these threads, this patch adds
	a new deferred_warnings parameter to the function, letting the caller
	control exactly how the warnings are emitted.

	Refactor complaint thread-safety approach
	This patch changes the way complaint works in a background thread.
	The new approach requires installing a complaint interceptor in each

	patch, where installing a complaint interceptor around a parallel-for
	is no longer a viable approach.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Add thread-safety to gdb's BFD wrappers
	This changes gdb to ensure that gdb's BFD cache is guarded by a lock.
	This avoids any races when multiple threads might open a BFD (and thus
	use the BFD cache) at the same time.

	Currently, this change is not needed because the the main thread waits
	for some DWARF scanning to be completed before returning.  The only
	locking that's required is when opening DWO files, and there's a local
	lock to this end in dwarf2/read.c.

	However, in the coming patches, the DWARF reader will begin its work
	earlier, in the background.  This means there is the potential for the
	DWARF reader and other code on the main thread to both attempt to open
	BFDs at the same time.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Add a couple of bfd_cache_close calls
	This adds a couple of calls to bfd_cache_close at points where a BFD
	isn't actively needed by gdb.  Normally at these points, all the
	needed section data is already mapped, so we can simply close the file
	descriptor.  This is harmless at worst, because if this is needed
	after all, the BFD file descriptor cache will reopen it.

	Pre-read DWZ section data
	This changes the DWZ code to pre-read the section data and somewhat
	simplify the DWZ API.  This makes it easier to add the bfd_cache_close
	call to the new dwarf2_read_dwz_file function -- after this is done,
	there shouldn't be a reason to keep the BFD's file descriptor open.

2024-01-09  Tom Tromey  <tom@tromey.com>

	Don't use objfile::intern in DWO code
	The DWO code in the DWARF reader currently uses objfile::intern.  This
	accesses a shared data structure and so would be racy when used from
	multiple threads.  I don't believe this can happen right now, but
	background reading could provoke this, and in any case it's better to
	avoid this, just to be sure.

	This patch changes this code to just use a std::string.  A new type is
	introduced to do hash table lookups, to avoid unnecessary copies.

	sim: cgen: rework DI macros to avoid signed left shifts
	The cgen code uses DI as int64_t and UDI as uint64_t.  The DI macros
	are used to construct 64-bit values from 32-bit values (for the low
	and high parts).  The MAKEDI macro casts the high 32-bit value to a
	signed 32-bit value before shifting.  If this created a negative
	value, this would be undefined behavior according to the C standard.
	All we care about is shifting the 32-bits as they are to the high
	32-bits, not caring about sign extension (since there's nothing left
	to shift into), and the low 32-bits being empty.  This is what we
	get from shifting an unsigned value, so cast it to unsigned 32-bit
	to avoid undefined behavior.

	While we're here, change the SETLODI macro to truncate the lower
	value to 32-bits before we set it.  If it was passing in a 64-bit
	value, those high bits would get included too, and that's not what
	we want.

	Similarly, tweak the SETHIDI macro to cast the value to an unsigned
	64-bit instead of a signed 64-bit.  If the value was only 32-bits,
	the behavior would be the same.  If it happened to be signed 64-bit,
	it would trigger the undefined behavior too.

	MIPS/GAS: mips.exp, mark all mipsisa32*-linux as addr32
	Currently, only mipsisa32-linux and mipsisa32el-linux is marked
	as addr32, which make mipsisa32rN(el) not marked.

	This change can fix 2 test failures on mipsisa32rN(el)-linux:
		FAIL: MIPS MIPS64 MIPS-3D ASE instructions (-mips3d flag)
		FAIL: MIPS MIPS64 MDMX ASE instructions (-mdmx flag)

	These failures don't happen for mipsisa32rN-mti-elf etc,
	due to that, the output is set as NO_ABI instead of O32, then
	gas won't warn:
		`fp=64' used with a 32-bit ABI
	Maybe, we should change this behaivour in future.

	arm: Add support for Armv8.9-A and Armv9.4-A
	This patch adds AArch32 support for -march=armv8.9-a and
	-march=armv9.4-a. The behaviour of the new options can be
	expressed using a combination of existing feature flags
	and tables.

	The cpu_arch_ver entries for ARM_ARCH_V9_4A and ARM_ARCH_V8_9A
	are technically redundant but it including them for macro code
	consistency across architectures.

	Add support for the aarch64-gnu target (GNU/Hurd on AArch64)
	Also recognized are aarch64-*-gnu tagrets, e.g. aarch64-pc-gnu or
	aarch64-unknown-gnu.

	The ld/emulparams/aarch64gnu.sh file is (for now) identical to aarch64fbsd.sh,
	or to aarch64linux.sh with Linux-specific logic removed; and mainly different
	from the generic aarch64elf.sh in that it does not set EMBEDDED=yes.

	Coupled with a corresponding GCC patch, this produces a toolchain that can
	sucessfully build working binaries targeting aarch64-gnu.

	[gdb/testsuite] Make gdb.base/solib-search.exp more robust
	On aarch64-linux, with gcc 13.2.1, I run into:
	...
	 (gdb) backtrace^M
	 #0  break_here () at solib-search.c:30^M
	 #1  0x0000fffff7f20194 in lib2_func4 () at solib-search-lib2.c:50^M

	   backtrace (with wrong libs) (data collection)
	 FAIL: gdb.base/solib-search.exp: backtrace (with wrong libs)
	...

	The FAIL is generated by this code in the test-case:
	...
	    if { $expect_fail } {
		# If the backtrace output is correct the test isn't sufficiently
		# testing what it should.
		if { $count == $total_expected } {
		    set fail 1
		}
	...

	The test-case:
	- builds two versions of two shared libs, a "right" and "wrong" version, the
	  difference being an additional dummy function (called spacer function),
	- uses the "right" version to generate a core file,
	- uses the "wrong" version to interpret the core file, and
	- generates a backtrace.

	The intent is that the backtrace is incorrect due to using the "wrong"
	version, but actually it's correct.  This is because the spacer functions
	aren't large enough.

	Fix this by increasing the size of the spacer functions by adding a dummy
	loop, after which we have, as expected, an incorrect backtrace:
	...
	 (gdb) backtrace^M
	 #0  break_here () at solib-search.c:30^M

	x86: corrections to CPU attribute/flags splitting
	There are a number of issues with 734dfd1cc966 ("x86: pack CPU flags in
	opcode table"):
	- the condition when two array slots need writing wasn't correct (with
	  enough new Cpu* added an out of bounds array access would validly have
	  been complained about by the compiler),
	- table generation didn't take into account CpuAttrUnused and CpuUnused
	  being independent, and hence there not always (not) being an "unused"
	  bitfield member in both structures,
	- cpu_flags_from_attr() wasn't ready for use on big-endian hosts,
	- there were two style violations.

	ELF: test certain .text/.data usages
	Various targets have / had overrides for .text and/or .data. Make sure
	that in such cases sub-section specifiers are accepted, as mandated by
	the doc.

	ELF: test certain .bss usages
	Various targets have / had overrides for .bss. Make sure that in such
	cases
	- .previous still works correctly (requiring such targets to invoke
	  obj_elf_section_change_hook() from their overriding handlers),
	- sub-section specifiers are accepted as far as feasible (mandated by

	Since the particularity of "th.vsetvli" was not taken into account in the

	due to instruction coding errors. According to T-Head SPEC ([1]), the
	"vsetvl" in the XTheadVector extension consists of SEW, LMUL and EDIV,
	which is quite different from the "V" extension. Therefore, we cannot
	simply reuse the processing of vsetvl in V extension.

	We have set up tens of thousands of test cases to ensure that no

	LoongArch: Fix linker generate PLT entry for data symbol
	With old "medium" code model, we call a function with a pair of PCALAU12I
	and JIRL instructions. The assembler produces something like:

	   8:	1a00000c 	pcalau12i   	$t0, 0
				8: R_LARCH_PCALA_HI20	g
	   c:	4c000181 	jirl        	$ra, $t0, 0
				c: R_LARCH_PCALA_LO12	g

	The linker generates a "PLT entry" for data without any diagnostic.
	If "g" is a data symbol and ld with -shared option, it may load two
	instructions in the PLT.

	Without -shared option, loongarch_elf_adjust_dynamic_symbol can delete PLT
	entry.

	For R_LARCH_PCALA_HI20 relocation, linker only generate PLT entry for STT_FUNC
	and STT_GNU_IFUNC symbols.

	gdb: improve error reporting from expression parser
	This commits changes how errors are reported from the expression
	parser.  Previously, parser errors were reported like this:

	  (gdb) p a1 +}= 432
	  A syntax error in expression, near `}= 432'.
	  (gdb) p a1 +
	  A syntax error in expression, near `'.

	The first case is fine, a user can figure out what's going wrong, but
	the second case is a little confusing; as the error occurred at the
	end of the expression GDB just reports the empty string to the user.

	After this commit the first case is unchanged, but the second case now
	reports like this:

	  (gdb) p a1 +
	  A syntax error in expression, near the end of `a1 +'.

	Which I think is clearer.  There is a possible issue if the expression
	being parsed is very long, GDB will repeat the whole expression.  But
	this issue already exists in the standard case; if the error occurs
	early in a long expression GDB will repeat everything after the syntax
	error.  So I've not worried about this case in my new code either,
	which keeps things simpler.

	I did consider trying to have multi-line errors here, in the style
	that gcc produces, with some kind of '~~~~~^' marker on the second
	line to indicate where the error occurred; but I rejected this due to
	the places in GDB where we catch an error and repackage the message
	within some longer string, I don't think multi-line error messages
	would work well in that case.  At a minimum it would require some
	significant work in order to make all our error handling multi-line
	aware.

	I've added a couple of extra tests in gdb.base/exprs.exp.

	gdb: merge error handling from different expression parsers
	Many (all?) of the expression parsers implement yyerror to handle
	parser errors, and all of these functions are basically identical.

	This commit adds a new parser_state::parse_error() function, which
	implements the common error handling code, this function can then be
	called from all the different yyerror functions.

	The benefit of this is that (in a future commit) I can improve the
	error output, and all the expression parsers will benefit.

	This commit is pure refactoring though, and so, there should be no
	user visible changes after this commit.

	gdb: don't try to style content in error calls
	While working on a later commit in this series I realised that the
	error() function doesn't support output styling.  Due to the way that
	output from error() calls is passed around within the exception
	object and often combined with other output, it's not immediately
	obvious to me if we should be trying to support styling in this
	context or not.

	On inspection, I found one place in GDB where we apparently try to
	apply styling within the error() output (in procfs.c).  I suspect this
	error() call might not be tested.

	Rather than try to implement styling in the error() output, right now
	I'm proposing to just remove the attempt to style error() output.

	This doesn't mean that someone shouldn't add error() styling in the
	future, but right now, I'm not planning to do that, I just wanted to
	fix this in passing.

	LoongArch: Fix some macro that cannot be expanded properly
	Suppose we want to use la.got to generate 32 pcrel and
	32 abs instruction sequences respectively. According to
	the existing conditions, to generate 32 pcrel sequences
	use -mabi=ilp32*, and to generate 32 abs use -mabi=ilp32*
	and -mla-global-with-abs.

	Due to the fact that the conditions for generating 32 abs
	also satisfy 32 pcrel, using -mabi=ilp32* and -mla-global-with-abs
	will result in only generating instruction sequences of 32 pcrel.

	By modifying the conditions for macro expansion and adjusting
	the matching order of macro instructions, it is ensured that
	the correct sequence of instructions can be generated.

	The filter.c module is still here because of the unique it_is API.
	The common igen code doesn't seem to have an equiv API as this only

	Some of the generated ppc code is now slightly different, but that's
	because of fixes the common igen code has gained, but not the ppc igen
	code (e.g. fixing of #line numbers).

	The ppc code retains lf_print__c_code because the common igen code

	sim: igen: clean up headers a bit
	Add standard multiple inclusion protection, and add a few missing
	local includes when one header uses another.  This isn't complete,
	but fixes some short comings seen when merging the ppc igen.

	sim: ppc: switch to common endian code
	The common sim-endian is a forked & updated version of the ppc code.
	Fortunately, they didn't diverge from the basic APIs, so they are
	still compatible, which means we can just delete the ppc version now
	that the build env is merged at the top-level.

	sim: common: include sim-types.h in the endian header directly
	This is a bit redundant for most ports as they go through sim-basics.h
	which always includes sim-types.h before including sim-endian.h, but in
	order to unify ppc's sim-endian code, we need this include here.  Plus,
	it's the directly we generally want to go to get away from one header
	that defines all APIs and causes hard to untangle dependencies.

	sim: ppc: rename local ALU SIGNED64 macros
	The common/ code has macros with the same name but different behavior:
	it's for declaring integer constants as 64-bit, not for casting them.
	Rename ppc's local variant since it's only used in this file in order
	to avoid conflicts.

	this framework to pass settings down to sub-makefiles.  Delete it all.

	This removes all recursive makes from the ppc port.

	The downside is that each object compile is a recursive make instead of
	a single one.  It adds some overhead, so it's not great, but it shouldn't
	be a big deal.  This will go away once compilation is hoisted up.

	Fix GDB reverse-step and reverse-next command behavior
	Currently GDB when executing in reverse over multiple statements in a single

	So far so good, a "next" stepped over the whole of line 11 and stopped at

	Let's confirm where we are now:

	 (gdb) disassemble /s

	Good, we're at the first instruction of line 12.

	Now let's undo the "next", with "reverse-next":

	 (gdb) reverse-next
	 11        func1 (); func2 ();

	Seemingly stopped at line 11.  Let's see exactly where:

	 (gdb) disassemble /s
	 Dump of assembler code for function main:

	 (gdb)

	And lo, we stopped in the middle of line 11!  That is a bug, we should have
	stepped back all the way to the beginning of the line.  The "reverse-next"
	should have fully undone the prior "next" command.

	--------------------

	This patch fixes the incorrect GDB behavior by ensuring that GDB  stops at
	the first instruction in the line.

	The test case gdb.reverse/func-map-to-same-line.exp is added to testsuite
	to verify this fix when the line table information is and is not available.

2024-01-02  Carl Love  <cel@linux.ibm.com>

	PowerPC and aarch64: Fix reverse stepping failure
	When running GDB's testsuite on aarch64-linux/Ubuntu 20.04 (also spotted on
	the ppc backend), there are failures in gdb.reverse/solib-precsave.exp and
	gdb.reverse/solib-reverse.exp.

	The failure happens around the following code:

	38  b[1] = shr2(17);          /* middle part two */
	40  b[0] = 6;   b[1] = 9;     /* generic statement, end part two */
	42  shr1 ("message 1\n");     /* shr1 one */

	Normal execution:

	- step from line 38 will land on line 40.
	- step from line 40 will land on line 42.

	Reverse execution:
	- step from line 42 will land on line 40.
	- step from line 40 will land on line 40.
	- step from line 40 will land on line 38.

	The problem here is that line 40 contains two contiguous but distinct
	PC ranges in the line table, like so:

	Line 40 - [0x7ec ~ 0x7f4]
	Line 40 - [0x7f4 ~ 0x7fc]

	The two distinct ranges are generated because GCC started outputting source
	column information, which GDB doesn't take into account at the moment.

	When stepping forward from line 40, we skip both of these ranges and land on
	line 42. When stepping backward from line 42, we stop at the start PC of the
	second (or first, going backwards) range of line 40.

	Since we've reached ecs->event_thread->control.step_range_start, we stop
	stepping backwards.

	The above issues were fixed by introducing a new function that looks for
	adjacent PC ranges for the same line, until we notice a line change. Then
	we take that as the start PC of the range.  The new start PC for the range
	is used for the control.step_range_start when setting up a step range.

	The test case gdb.reverse/map-to-same-line.exp is added to test the fix
	for the above reverse step issues.

	Patch has been tested on PowerPC, X86 and AArch64 with no regressions.

	Patch has been tested on PowerPC with both gcc and clang.

	gdb/dwarf2: Add support for DW_LNS_set_epilogue_begin in line-table
	This commit adds a mechanism for GDB to detect the linetable opcode
	DW_LNS_set_epilogue_begin. This opcode is set by compilers to indicate
	that a certain instruction marks the point where the frame is destroyed.

	While the standard allows for multiple points marked with epilogue_begin
	in the same function, for performance reasons, the function that
	searches for the epilogue address will only find the last address that
	sets this flag for a given block.

	This commit also changes amd64_stack_frame_destroyed_p_1 to attempt to
	use the epilogue begin directly, and only if an epilogue can't be found
	will it attempt heuristics based on the current instruction.

	Finally, this commit also changes the dwarf assembler to be able to emit
	epilogue-begin instructions, to make it easier to test this patch

	AC_MSG_CHECKING & AC_MSG_RESULT calls.  Also delete pointless
	variable setting after calling AC_MSG_ERROR.

	sim: ppc: switch to AS_HELP_STRING for automatic formatting

	sim: ppc: drop now unused config.in

	sim: ppc: move defines.h generation to the top-level
	Since we rely on the top-level config.h now, the defines.h generation
	step should live here too.

	sim: ppc: drop configure compiler checks
	Now that the ppc script only checks configure options and sets up
	variables in the Makefile from those, delete all the compile related
	logic to greatly simplify the configure script.

	sim: ppc: drop custom config.h header
	Now that everything has moved to the top-level, we can drop the
	custom ppc config.h and reuse the common one.

	sim: ppc: stop including headers from gdb/
	The common sim code doesn't snoop in gdb/, and the ppc code doesn't
	need to either.  Any common code we pull from gnulib/ now only.

	sim: ppc: move termios probes to top-level
	This is the last compile-time logic in the ppc subdir.

	sim: ppc: switch to AC_CACHE_CHECK
	This macro replaces the AC_MSG_CHECKING+AC_CACHE_VAL+AC_MSG_RESULT
	which reduces the boilerplate in here a little bit.

	sim: ppc: switch struct member checks to AC_CHECK_MEMBER
	This covers a lot of the AC_MSG_CHECKING+AC_TRY_COMPILE+AC_MSG_RESULT
	boilerplate and matches what we do in the top-level platform checks.

	sim: ppc: move termio defines to config.h
	Move the defines from explicit -D options to config.h defines to simplify
	the build and make it easier to move to the top-level configure.

	sim: ppc: move struct statfs to top-level

	sim: ppc: move long long test to top-level
	While the sim code doesn't utilize HAVE_LONG_LONG itself, other code
	(like libiberty) seem to, so check for it in the top-level for all
	ports to leverage.

	sim: ppc: hoist sysv tests to top-level
	Now that the sysv tests turn into config.h defines and everything
	checks that, we can move the tests to the top-level and out of the
	ppc subdir.

2024-01-02  Mike Frysinger  <vapier@gentoo.org>

	sim: ppc: always compile in the sysv sem & shm device files
	Move the stub logic to the device files themselves.  This makes the
	configure & build logic more static which will make it easier to move
	to the top-level build, and matches what we did with the common/ hw
	tree already.

	This also decouples the logic from the two -- in the past, you needed
	both sem & shm in order to enable the device models, but now each one
	is tied to its own independent knob.  Practically speaking, this will
	probably not make a difference, but it simplifies the build a bit.

2024-01-02  Mike Frysinger  <vapier@gentoo.org>

	sim: ppc: change SysV sem & shm tests to compile-time
	Instead of executing code to see if SysV semaphores & shared memory
	are available, switch to just a compile-time test.  The system used
	to compile might not match the system used to run the code wrt the
	current kernel & OS settings, but the library APIs should.  So move
	the failures from compile-time to runtime so the program is more
	portable, and works correctly even when cross-compiling.

2024-01-02  Mike Frysinger  <vapier@gentoo.org>

	sim: ppc: merge System V semaphores checks
	Compile tests can use earlier defines, so hoist the HAVE_UNION_SEMUN
	define to before the semaphore check, and use it in the test so that
	we can merge the 2 versions into one.

	This also defines HAVE_UNION_SEMUN even when ac_cv_sysv_sem is not
	set, but that's OK as this define is only about a type existing, not
	about whether the overall code is usable.

2024-01-02  Mike Frysinger  <vapier@gentoo.org>

	sim: ppc: fix bad AC_CACHE_CHECK call with semun
	The first arg is the cache var name, and this one was typoed relative
	to what the call actually set.  We also don't need the manual call to
	AC_MSG_RESULT as the AC_CACHE_CHECK takes care of it for us.

	sim: ppc: delete unused build compile & link settings
	These should have been removed as part of the ppc/igen merging into the
	top-level, but they were missed.  Clean up now.

	sim: ppc: merge misc igen APIs
	The common igen code provides the same misc APIs as the ppc version,
	so delete the ppc code and pull in the common one.  There is one
	minor difference: the ppc code has a unique dumpf function.  The
	common code switched to lf_printf for the same functionality, but
	since that requires changes throughout the igen codebase, delay that
	cleanup for now so we can merge the rest.

	sim: ppc: rework igen error to match common
	Switch to an ERROR macro and tweak the error signature to match the
	common igen version in preparation for merging the two implementations.

	sim: igen: extend error to take arguments
	The ppc igen error helper allows arbitrary printf calls, so extend
	the common one to do the same.

	sim: ppc: rename igen max_insn_bit_size
	We want to avoid conflicts with the common igen enums.  This should
	get migrated over to the common parsing logic, but for now, switch
	the name to avoid redefinition.

	sim: igen: minor constify logic
	Copy some improvements from the ppc igen code.

	sim: ppc: unify igen filter_filename implementations
	Now that both igen implementations are in the top-level, we can unify
	the filter_filename implementation between them since they're the same
	(literally the same code).

	sim: ppc: replace filter_filename with lbasename
	The lbasename function from libiberty provides the same API as this
	custom function.  The common/ code already made the switch, so make
	the same change to the ppc code to avoid target duplication.

	sim: ppc: hoist igen compilation into top-level
	This simplifies the build a bit (especially for deps in port subdirs),
	and avoids recursive make.  This in turn speeds up the build, and lets
	us reuse existing build-time vs host-time logic from Makefile.am.

	sim: ppc: drop build-config.h usage
	This header is only used by the igen tool, and none of the igen code
	depends on the configure-time checks.  Delete the logic to simplify
	to prepare for moving it to the local.mk code.

	sim: ppc: simplify filter_host.c logic
	Switch this from a build-time generation to a static include.  This
	makes the build rules a bit simpler, especially as we move them to
	Automake from hand-written makefiles.

	sim: igen: remove libigen.a when cleaning

	sim: ppc: drop unused host bitsize settings
	This is never set anywhere, so it's always empty.  Scrub it.

	sim: frv: fix cmpb uninitialized variable usage
	This code sets up the cc variable based on the comparison of other
	registers, but it does so incrementally with bit operations, and it
	never initializes the cc variable.  Initialize it to 0 which the
	cmpba insn is already doing.

	sim: arm: mark local read-only arrays as static const
	Move it into read-only data sections to avoid constructing them on the
	stack at runtime.

	sim: warnings: enable -Wunused-variable

	cpu: or1k: drop unused l.swa flag
	The "flag" argument isn't set/used in this insn, so drop it.
	This fixes an unused variable warning in the generated sim.

	(gdb) PASS: gdb.base/catch-syscall.exp: determine pipe syscall: \

	SYS_pipe2:
	...
	  -re -wrap "Catchpoint $decimal \\(call to syscall (pipe2|$SYS_pipe)\\).*" {
	...
	and consequently doesn't handle the pipe2 syscall number.

	dwarf, fortran: add support for DW_TAG_entry_point
	Fortran provides additional entry points for subroutines and functions.
	These entry points may use only a subset (or a different set) of the
	parameters of the original subroutine.  The entry points may be described
	via the DWARF tag DW_TAG_entry_point.

	This commit adds support for parsing the DW_TAG_entry_point DWARF tag.
	Currently, between ifx/ifort/gfortran, only ifort is actually emitting
	this tag.  Both, ifx and gfortran use the DW_TAG_subprogram tag as
	workaround/alternative.  Thus, this patch really only adds more ifort
	support.  Even so, some of the attached tests still fail for ifort, due
	to some wrong line info generated for the entry points in ifort.

	After this patch it is possible to set a breakpoint in gdb with the
	ifort compiled example at the entry points 'foo' and 'foobar', which was not
	possible before.

	As gcc and ifx do not emit the tag I also added a test to gdb.dwarf2
	which uses some underlying c compiled code and adds some Fortran style DWARF
	to it emitting the DW_TAG_entry_point.  Before this patch it was not
	possible to actually define breakpoint at the entry point tags.

	For gfortran there actually exists a bug on bugzilla, asking for the use
	of DW_TAG_entry_point over DW_TAG_subprogram:

	https://gcc.gnu.org/bugzilla/show_bug.cgi?id=37134

	This patch was originally posted here

	https://sourceware.org/legacy-ml/gdb-patches/2017-07/msg00317.html

	but its review/pinging got lost after a while.  I reworked it to fit the
	current GDB.

	This commit is in preparation of the next commit.  There, we will add
	a second variation to retrieve the pc bounds for DIEs tagged with
	DW_TAG_entry_point.  Instead of dwarf_get_pc_bounds_ranges_or_highlow_pc
	we will call a separate method for entry points.  As the validity checks
	at the endo f dwarf2_get_pc_bounds are the same for both variants,
	we introduced the new dwarf_get_pc_bounds_ranges_or_highlow_pc method,
	outsourcing part of dwarf2_get_pc_bounds.

	Support APX GPR32 with extend evex prefix
	This patch adds non-ND, non-NF forms of EVEX promotion insn.

	EVEX extension of legacy instructions:
	  All promoted legacy instructions are placed in EVEX map 4, which is
	  currently reserved.
	EVEX extension of EVEX instructions:
	  All existing EVEX instructions are extended by APX using the extended
	  EVEX prefix, so that they can access all 32 GPRs.
	EVEX extension of VEX instructions:
	  Promoting a VEX instruction into the EVEX space does not change the map
	  id, the opcode, or the operand encoding of the VEX instruction.

	Note: The promoted versions of MOVBE will be extended to include the “MOVBE
	  reg1, reg2”.

	sim: pru: Fix emulation of carry bit
	The PRU architecture documentation [1] was used for the initial GNU
	simulator implementation.  But recently [2] TI confirmed the carry
	behaviour was wrongly documented.  In reality, the PRU carry behaves
	like the carry in ARM processors.

	This patch fixes simulator to align with latest recommendations from TI.

	The new carry.s test was also validated to pass on real hardware -
	a BeaglePlay board [3].  That test is a bit long because TI still
	has not released official updates for the PRU documents.  And I wanted
	to ensure simulator handles all edge cases exactly as the real hardware
	does.

	RISC-V: Clarify the behaviors of SET/ADD/SUB relocations

	* Bugzilla,
	https://sourceware.org/bugzilla/show_bug.cgi?id=31179#c5

	The addend of SUB_ULEB128 should be zero if using .uleb128, but we make it
	non-zero by accident in assembler before.  This causes troubles by applying
	the above commit, since the calculation is changed to support .reloc *SUB*
	relocations with non-zero addend.

	We encourage people to rebuild their stuff to get the non-zero addend of
	SUB_ULEB128, but that might need some times, so report warnings to inform
	people need to rebuild their stuff if --check-uleb128 is enabled.

	Since the failed .reloc cases for ADD/SET/SUB/ULEB128 are rarely to use,
	it may acceptable that stop supproting them until people rebuld their stuff,
	maybe half-year or a year later.  Or maybe we should teach people that don't
	write the .reloc R_RISCV_SUB* with non-zero constant, and then report
	warnings/errors in assembler.

	bfd/
		* elfnn-riscv.c (perform_relocation): Ignore the non-zero addend of
		R_RISCV_SUB_ULEB128.
		(riscv_elf_relocate_section): Report warnings to inform people need

		* elfxx-riscv.h (struct riscv_elf_params): Added bool check_uleb128.

		* NEWS: Updated.
		* emultempl/riscvelf.em: Added linker risc-v target options,

	LoongArch: Add support for TLS LD/GD/DESC relaxation
	The pcalau12i + addi.d of TLS LD/GD/DESC relax to pcaddi.
	Relaxation is only performed when the TLS model transition is not possible.

2023-12-25  Lulu Cai  <cailulu@loongson.cn>

	LoongArch: Add tls transition support.
	Transitions between DESC->IE/LE and IE->LE are supported now.
	1. For DESC -> LE:
	   pcalau12i  $a0,%desc_pc_hi20(var)     =>  lu12i.w $a0,%le_hi20(var)
	   addi.d     $a0,$a0,%desc_pc_lo12(var) =>  ori $a0,$a0,%le_lo12(var)
	   ld.d       $a1,$a0,%desc_ld(var)      =>  NOP
	   jirl       $ra,$a1,%desc_call(var)	 =>  NOP
	   add.d      $a0,$a0,$tp
	2. For DESC -> IE:
	   pcalau12i  $a0,%desc_pc_hi20(var)     =>  pcalau12i $a0,%ie_pc_hi20(var)
	   addi.d     $a0,$a0,%desc_pc_lo12(var) =>  ld.d $a0,$a0,%ie_pc_lo12(var)
	   ld.d       $a1,$a0,%desc_ld(var)      =>  NOP
	   jirl       $ra,$a1,%desc_call(var)	 =>  NOP
	   add.d      $a0,$a0,$tp
	3. For IE -> LE:
	   pcalau12i  $a0,%ie_pc_hi20(var)       =>  lu12i.w $a0,%le_hi20(var)
	   ld.d       $a0,$a0,%ie_pc_lo12(var)   =>  ori $a0,$a0,%le_lo12(var)
	   add.d      $a0,$a0,$tp
	4. When a tls variable is accessed using both DESC and IE, DESC transitions
	   to IE and uses the same GOT entry as IE.

	LoongArch: Add support for TLSDESC in ld.
	1.The linker for each DESC generates a R_LARCH_TLS_DESC64 dynamic
	  relocation, which relocation is placed at .rela.dyn.
	  TLSDESC always allocates two GOT slots and one dynamic relocation
	  space to TLSDESC.
	2. When using multiple ways to access the same TLS variable, a
	   maximum of 5 GOT slots are used. For example, using GD, TLSDESC,
	   and IE to access the same TLS variable, GD always uses the first
	   two of the five GOT, TLSDESC uses the third and fourth, and IE
	   uses the last.

	LoongArch: Add new relocs and macro for TLSDESC.
	The normal DESC instruction sequence is:
	  pcalau12i  $a0,%desc_pc_hi20(var)     #R_LARCH_TLS_DESC_PC_HI20
	  addi.d     $a0,$a0,%desc_pc_lo12(var) #R_LARCH_TLS_DESC_PC_LO12
	  ld.d       $ra,$a0,%desc_ld(var)	#R_LARCH_TLS_DESC_LD
	  jirl       $ra,$ra,%desc_call(var)	#R_LARCH_TLS_DESC_CALL

	gdb: make value::allocate_register_lazy store id of next non-inline frame
	Some spots loop on the frame chain to find the first next non-inline
	frame, and pass that as the "next frame" to
	value::allocate_register_lazy / value::allocate_register.  This is
	necessary if the value is used in the process of computing the id of
	"this frame".  If the frame next to "this frame" is inlined into "this
	frame", then you that next frame won't have a computed id yet.  You have
	to go past that to find the next non-inline frame, which will have a
	computed id.

	In other cases, it's fine to store the id of an inline frame as the
	"next frame id" in a register struct value.  When trying to unwind a
	register from it, it will just call inline_frame_prev_register, which
	will forward the request to the next next frame, until we hit the next
	physical frame.

	I think it would make things simpler to just never store the id of an
	inline frame as the next frame id of register struct values, and go with
	the first next non-inline frame directly.  This way, we don't have to
	wonder which code paths have to skip inline frames when creating
	register values and which don't.

	So, change value::allocate_register_lazy to do that work, and remove the
	loops for the callers that did it.

	gdb: implement address_from_register using value_from_register
	As explained in the comment removed by the previous commit "gdb: pass
	non-nullptr frame to gdbarch_value_from_register in
	address_from_register", address_from_register copies some implementation
	bits from value_from_register:

	   /* This routine may be called during early unwinding, at a time
	      where the ID of FRAME is not yet known.  Calling value_from_register
	      would therefore abort in get_frame_id.  However, since we only need
	      a temporary value that is never used as lvalue, we actually do not
	      really need to set its VALUE_NEXT_FRAME_ID.  Therefore, we re-implement
	      the core of value_from_register, but use the null_frame_id.  */

	This is no longer relevant, since we now create a value with a valid next
	frame id, so change address_from_register to use value_from_register.

	Add a value::allocate_register_lazy method.  Add some type parameters

	gdb: pass non-nullptr frame to gdbarch_value_from_register in address_from_register
	address_from_register used to pass null_frame_id to
	gdbarch_value_from_register as "this frame"'s id, because it's possible
	for it to be called during unwind, when "this frame"'s id is not yet
	known.  This create an oddity where those register struct values are
	created without a valid next frame id.  I would much prefer for things
	to be consistent and have all register struct values to have a valid
	next frame id.

	Since gdbarch_value_from_register takes a frame_info_ptr now, rather
	than a frame_id, we can pass down "this frame", even if it doesn't have
	a valid id.  gdbarch_value_from_register implementations can obtain the
	next frame from it.

	However, it's possible for the "this frame"'s next frame to be an
	inline frame, inlined in "this frame", in which case that next frame's
	id is also not known.  So, loop until we get to the next non-inline
	frame (which is actually the frame where registers for "this frame" are
	unwound from).  This is the same thing that we do in
	value_of_register_lazy, for the same reason.  A later patch will factor
	out this "while next frame is inline" loop to apply it to all register
	struct values, so this is somewhat temporary.

	sim: cris: disable -Wshadow=local in generated mloop files
	The mloop files include CGEN generated switch files which have some
	nested assignments that expand into repeated shadowed variables.
	Fixing this looks fairly non-trivial as it appears to be interplay
	between the common CGEN code and how this particular set of cris
	insns are defined.  Disable the warning instead.

	In file included from sim/cris/mloop.in:286:
	sim/cris/semcrisv10f-switch.c: In function ‘crisv10f_engine_run_full’:
	sim/cris/semcrisv10f-switch.c:12383:8: error: declaration of ‘opval’ shadows a previous local [-Werror=shadow=local]
	12383 |     SI opval = tmp_addr;
	      |        ^~~~~
	sim/cris/semcrisv10f-switch.c:12371:9: note: shadowed declaration is here
	12371 |     USI opval = ({   SI tmp_addr;
	      |         ^~~~~

	And the code looks like:
		USI opval = ({
			...
				{
					SI opval = tmp_addr;
					...
				}
			...
		});

	Since the CGEN code treats "opval" as an internal variable that the cpu
	definitions don't have direct access to, the likelihood of this being a
	real bug is low, so leave it be.  The warning is suppressed for more code
	that is hand written (e.g. the mloop logic), but disabling for the entire
	file is the easiest way to suppress while keeping it on everywhere else in
	the sim.

	Avoid exception from attach in DAP
	I noticed that the DAP attach test case (and similarly
	remoted-dap.exp) had a rogue exception stack trace in the log.  It
	turns out that an attach will generate a stop that does not have a
	reason.

	This patch fixes the problem in the _on_stop event listener by making
	it a bit more careful when examining the event reason.  It also adds
	some machinery so that attach stops can be suppressed, which I think
	is the right thing to do.

	gdb: add git trailer information on gdb/MAINTAINERS
	The project has been using Tested-By (tb), Reviewed-By (rb) and
	Approved-By (ab) for some time, but there has been no information to be
	found in the actual repository. This commit changes that by adding
	information about all git trailers to the MAINTAINERS file, so that it
	can be easily double-checked. Simply put, the trailers in use work as
	follows:

	* Tested-by: The person tested the patch and it fixes the problem, or
	  introduces no regressions (or both).
	* Acked-by: The general outline looks good, but the maintainer hasn't
	  looked at the code
	* Reviewed-by: The code looks good, but the reviewer has not approved
	  the patch to go upstream
	* Approved-by: The patch is ready to be pushed to master

	These last 3 trailers can also be restricted to one or more areas of GDB
	by adding the areas in a comma separated list in parenthesis after the
	trailers.

	Finally, for completeness sake, the trailers Co-Authored-By and Bug
	were added, even though they have been in use for a long time already

	only starting with APX - permit use of "new" 8-bit registers only. %ah,
	%ch, %dh, and %bh cannot be encoded and hence should be rejected.

	x86: properly respect rex/{rex}
	This addresses two issues: For one, a user specified "rex" did not cause
	the diagnostic to trigger when there was no other need for a REX prefix;
	instead, another than the specified insn+operands was encoded. And then
	(which is what this started from) .insn didn't respect {rex} (and was
	otherwise similarly flawed as ordinary insns).

	The latter requires splitting out code from md_assemble(), for it to
	become re-usable. Besides the addition to address the first issue, that
	code then also needs generalizing to account for immediate operands, as
	with .insn we can't make assumptions anymore on all respective templates
	having at most two operands (we still can build upon there being at most
	two non-immediate operands, though). While moving the code also simplify
	the first if(), by folding redundant checks.

	In the new testcase also test a few more things which afaics weren't
	tested till now.

	pragmas, we can point people to the original source files.

	Unfortunately, this code is written in POSIX shell, and that lacks
	support for line number tracking.  The $LINENO variable, even when
	available, can just be plain wrong.  For example, when using dash
	and subshells, $LINENO can end up having negative values.  Add a

	to the right value to avoid all that.

	Basically lineno.sh takes an input script, rewrites all uses of
	$LINENO into the actual line number (and $0 into the original file
	name), and then executes the temporary script.

	Fix Clang build issue with flexible array member and non-trivial dtor
	Commit d5cebea18e7a ("Make cached_reg_t own its data") added a
	destructor to cached_reg_t.

	That caused a build problem with Clang, which errors out like so:

	 > CXX    python/py-unwind.o
	 > gdb/python/py-unwind.c:126:16: error: flexible array member 'reg' of type 'cached_reg_t[]' with non-trivial destruction
	 >   126 |   cached_reg_t reg[];
	 >       |                ^

	This is is not really a problem for our code, which allocates the
	whole structure with xmalloc, and then initializes the array elements
	with in-place new, and then takes care to call the destructor
	manually.  Like, commit d5cebea18e7a did:

	 @@ -928,7 +927,7 @@ pyuw_dealloc_cache (frame_info *this_frame, void *cache)
	    cached_frame_info *cached_frame = (cached_frame_info *) cache;

	    for (int i = 0; i < cached_frame->reg_count; i++)
	 -    xfree (cached_frame->reg[i].data);
	 +    cached_frame->reg[i].~cached_reg_t ();

	Maybe we should get rid of the flexible array member and use a bog
	standard std::vector.  I doubt this would cause any visible
	performance issue.

	Meanwhile, to unbreak the build, this commit switches from C99-style
	flexible array member to 0-length array.  It behaves the same, and
	Clang doesn't complain.  I got the idea from here:

	  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70932#c11

	GCC 9, our oldest support version, already supported this:

	  https://gcc.gnu.org/onlinedocs/gcc-9.1.0/gcc/Zero-Length.html

	but the extension is actually much older than that.  Note that
	C99-style flexible array members are not standard C++ either.

	Fix handling of vanishing threads that were stepping/stopping
	Downstream, AMD is carrying a testcase
	(gdb.rocm/continue-over-kernel-exit.exp) that exposes a couple issues
	with the amd-dbgapi target's handling of exited threads.  The test
	can't be added upstream yet, unfortunately, due to dependency on DWARF
	extensions that can't be upstreamed yet.  However, it can be found on
	the mailing list on the same series as this patch.

	The test spawns a kernel with a number of waves.  The waves do nothing
	but exit.  There is a breakpoint on the s_endpgm instruction.  Once
	that breakpoint is hit, the test issues a "continue" command.  We
	should see one breakpoint hit per wave, and then the whole program
	exiting.  We do see that, however we also see this:

	 [New AMDGPU Wave ?:?:?:1 (?,?,?)/?]
	 [AMDGPU Wave ?:?:?:1 (?,?,?)/? exited]
	 *repeat for other waves*
	 ...
	 [Thread 0x7ffff626f640 (LWP 3048491) exited]
	 [Thread 0x7fffeb7ff640 (LWP 3048488) exited]
	 [Inferior 1 (process 3048475) exited normally]

	That "New AMDGPU Wave" output comes from infrun.c itself adding the
	thread to the GDB thread list, because it got an event for a thread
	not on the thread list yet.  The output shows "?"s instead of proper
	coordinates, because the event was a TARGET_WAITKIND_THREAD_EXITED,
	i.e., the wave was already gone when infrun.c added the thread to the
	thread list.

	That shouldn't ever happen for the amd-dbgapi target, threads should
	only ever be added by the backend.

	Note "New AMDGPU Wave ?:?:?:1" is for wave 1.  What happened was that
	wave 1 terminated previously, and a previous call to
	amd_dbgapi_target::update_thread_list() noticed the wave had vanished
	and removed it from the GDB thread list.  However, because the wave
	was stepping when it terminated (due to the displaced step over the
	s_endpgm) instruction, it is guaranteed that the amd-dbgapi library
	queues a WAVE_COMMAND_TERMINATED event for the exit.

	When we process that WAVE_COMMAND_TERMINATED event, in
	amd-dbgapi-target.c:process_one_event, we return it to the core as a
	TARGET_WAITKIND_THREAD_EXITED event:

	 static void
	 process_one_event (amd_dbgapi_event_id_t event_id,
			    amd_dbgapi_event_kind_t event_kind)
	 {
	 ...
		 if (status == AMD_DBGAPI_STATUS_ERROR_INVALID_WAVE_ID
		     && event_kind == AMD_DBGAPI_EVENT_KIND_WAVE_COMMAND_TERMINATED)
		   ws.set_thread_exited (0);
	 ...
	 }

	Recall the wave is already gone from the GDB thread list.  So when GDB
	sees that TARGET_WAITKIND_THREAD_EXITED event for a thread it doesn't
	know about, it adds the thread to the thread list, resulting in that:

	 [New AMDGPU Wave ?:?:?:1 (?,?,?)/?]

	and then, because it was a TARGET_WAITKIND_THREAD_EXITED event, GDB
	marks the thread exited right afterwards:

	 [AMDGPU Wave ?:?:?:1 (?,?,?)/? exited]

	The fix is to make amd_dbgapi_target::update_thread_list() _not_
	delete vanishing waves iff they were stepping or in progress of being
	stopped.  These two cases are the ones dbgapi guarantees will result
	in a WAVE_COMMAND_TERMINATED event if the wave terminates:

	  /**
	   * A command for a wave was not able to complete because the wave has
	   * terminated.
	   *
	   * Commands that can result in this event are ::amd_dbgapi_wave_stop and
	   * ::amd_dbgapi_wave_resume in single step mode.  Since the wave terminated
	   * before stopping, this event will be reported instead of
	   * ::AMD_DBGAPI_EVENT_KIND_WAVE_STOP.
	   *
	   * The wave that terminated is available by the ::AMD_DBGAPI_EVENT_INFO_WAVE
	   * query.  However, the wave will be invalid since it has already terminated.
	   * It is the client's responsibility to know what command was being performed
	   * and was unable to complete due to the wave terminating.
	   */
	  AMD_DBGAPI_EVENT_KIND_WAVE_COMMAND_TERMINATED = 2,

	As the comment says, it's GDB's responsability to know whether the
	wave was stepping or being stopped.  Since we now have a wave_info map
	with one entry for each wave, that seems like the place to store that
	information.  However, I still decided to put all the coordinate
	information in its own structure.  I.e., basically renamed the
	existing wave_info to wave_coordinates, and then added a new wave_info
	structure that holds the new state, plus a wave_coordinates object.
	This seemed cleaner as there are places where we only need to
	instantiate a wave_coordinates object.

	There's an extra twist.  The testcase also exercises stopping at a new
	kernel right after the first kernel fully exits.  In that scenario, we
	were hitting this assertion after the first kernel fully exits and the
	hit of the breakpoint at the second kernel is handled:

	 [amd-dbgapi] process_event_queue: Pulled event from dbgapi: event_id.handle = 26, event_kind = WAVE_STOP
	 [amd-dbgapi-lib] suspending queue_3, queue_2, queue_1 (refresh wave list)
	 ../../src/gdb/amd-dbgapi-target.c:1625: internal-error: amd_dbgapi_thread_deleted: Assertion `it != info->wave_info_map.end ()' failed.
	 A problem internal to GDB has been detected,
	 further debugging may prove unreliable.

	This is the exact same problem as above, just a different
	manifestation.  In this scenario, we end up in update_thread_list
	successfully deleting the exited thread (because it was no longer the
	current thread) that was incorrectly added by infrun.c.  Because it
	was added by infrun.c and not by amd-dbgapi-target.c:add_gpu_thread,
	it doesn't have an entry in the wave_info map, so
	amd_dbgapi_thread_deleted trips on this assertion:

	      gdb_assert (it != info->wave_info_map.end ());

	here:

	  ...
	  -> stop_all_threads
	   -> update_thread_list
	    -> target_update_thread_list
	     -> amd_dbgapi_target::update_thread_list
	      -> thread_db_target::update_thread_list
	       -> linux_nat_target::update_thread_list
		-> delete_exited_threads
		 -> delete_thread
		  -> delete_thread_1
		   -> gdb::observers::observable<thread_info*>::notify
		    -> amd_dbgapi_thread_deleted
		     -> internal_error_loc

	The testcase thus tries both running to exit after the first kernel
	exits, and running to a breakpoint in a second kernel after the first
	kernel exits.

	Fix thread target ID of exited waves
	Currently, if you step over kernel exit, you see:

	 stepi
	 [AMDGPU Wave ?:?:?:1 (?,?,?)/? exited]
	 Command aborted, thread exited.
	 (gdb)

	Those '?' are because the thread/wave is already gone by the time GDB
	prints the "exited" notification, we can't ask dbgapi for any info
	about the wave anymore.

	This commit fixes it by caching the wave's coordinates as soon as GDB
	sees the wave for the first time, and making
	amd_dbgapi_target::pid_to_str use the cached info.

	At first I thought of clearing the wave_info object from a
	thread_exited observer.  However, that is too soon, resulting in this:

	 (gdb) si
	 [AMDGPU Wave 1:4:1:1 (0,0,0)/0 exited]
	 Command aborted, thread exited.
	 (gdb) thread
	 [Current thread is 6 (AMDGPU Wave ?:?:?:0 (?,?,?)/?) (exited)]

	We need instead to clear the wave info when the thread is ultimately
	deleted, so we get:

	 (gdb) si
	 [AMDGPU Wave 1:4:1:1 (0,0,0)/0 exited]
	 Command aborted, thread exited.
	 (gdb) thread
	 [Current thread is 6 (AMDGPU Wave 1:4:1:1 (0,0,0)/0) (exited)]

	And for that, we need a new thread_deleted observable.

	Step over thread exit, always delete the thread non-silently
	With AMD GPU debugging, I noticed that when stepping over a breakpoint
	placed on top of the s_endpgm instruction inline (displaced=off), GDB
	would behave differently -- it wouldn't print the wave exit.  E.g:

	With displaced stepping, or no breakpoint at all:

	 stepi
	 [AMDGPU Wave 1:4:1:1 (0,0,0)/0 exited]
	 Command aborted, thread exited.
	 (gdb)

	With inline stepping:

	 stepi
	 Command aborted, thread exited.
	 (gdb)

	In the cases we see the "exited" notification, handle_thread_exit is
	what first called delete_thread on the exiting thread, which is
	non-silent.

	With inline stepping, however, handle_thread_exit ends up in
	update_thread_list (via restart_threads) before any delete_thread
	call.  Thus, amd_dbgapi_target::update_thread_list notices that the
	wave is gone and deletes it with delete_thread_silent.

	This commit fixes it, by making handle_thread_exited call
	set_thread_exited (with the default silent=false) early, which emits
	the user-visible notification.

	Ensure selected thread after thread exit stop
	While making step over thread exit work properly on AMDGPU, I noticed
	that if there's a breakpoint on top of the exit syscall, and,
	displaced stepping is off, then when GDB reports "Command aborted,
	thread exited.", GDB also switches focus to a random thread, instead
	of leaving the exited thread as selected:

	 (gdb) thread
	 [Current thread is 6, lane 0 (AMDGPU Lane 1:4:1:1/0 (0,0,0)[0,0,0])]
	 (gdb) si
	 Command aborted, thread exited.
	 (gdb) thread
	 [Current thread is 5 (Thread 0x7ffff626f640 (LWP 3248392))]
	 (gdb)

	The previous patch extended gdb.threads/step-over-thread-exit.exp to
	exercise this on GNU/Linux (on the CPU side), and there, after that
	"si", we always end up with the exiting thread as selected even
	without this fix, but that's just a concidence, there's a code path
	that happens to select the exiting thread for an unrelated reason.

	This commit add the explict switch, fixing the latent problem for
	GNU/Linux, and the actual problem on AMDGPU.  I wrote a gdb.rocm/
	testcase for this, but it can't be upstreamed yet, until more pieces
	of the DWARF machinery are upstream as well.

	gdb.threads/step-over-thread-exit.exp improvements
	This commit makes the following improvements to

	- Add a third axis to stepping over the breakpoint with displaced vs
	  inline stepping -- also test with no breakpoint at all.

	- Check that when GDB reports "Command aborted, thread exited.", the
	  selected thread is the thread that exited.  This is always true
	  currently on GNU/Linux by coincidence, but a similar testcase on AMD
	  GPU exposed a problem here.  Better make the testcase catch any

	- Fixes a race that Simon ran into with GDBserver testing.

	  I was not able to reproduce it, but I believe that what happens is
	  the following:

	  Once we continue, the thread 2 exits, and the main thread thus
	  unblocks from its pthread_join, and spawns a new thread.  That new
	  thread may hit the breakpoint at my_exit_syscall very quickly.  GDB
	  could then see/process that breakpoint event before the thread exit
	  event for the thread we care about, which would result in the
	  failure seen above.

	  The fix here is to not loop and start a new thread at all in the
	  scenario where the race can happen.  We only need to loop and spawn
	  new threads when testing with "cmd=continue" and schedlock off, in
	  which case GDB doesn't abort the command when the thread exits.

	Fix bug in previous remote unique_ptr change
	By inspection, I noticed that the previous patch went too far, here:

	    if (rs->remote_desc == NULL)

	    if (reply != NULL && reply->ptid.pid () == inf->pid)

	That is always moving the stop reply from pending_event, when we only

	gdb: register frame_destroyed function for amd64 gdbarch
	gdbarches usually register functions to check when a frame is destroyed
	which is used with software watchpoints, since the expression of the
	watchpoint is no longer vlaid at this point.  On amd64, this wasn't done
	anymore because GCC started using CFA for variable locations instead.

	However, clang doesn't use the CFA and instead relies on specifying when
	an epilogue has started, meaning software watchpoints get a spurious hit
	when a frame is destroyed. This patch re-adds the code to register the
	function that detects when a frame is destroyed, but only uses this when
	the producer is LLVM, so gcc code isn't affected. The logic that
	identifies the epilogue has been factored out into the new function
	amd64_stack_frame_destroyed_p_1, so the frame sniffer can call it
	directly, and its behavior isn't changed.

	This can also remove the XFAIL added to gdb.python/pq-watchpoint tests
	that handled this exact flaw in clang.

	LoongArch: Allow la.got -> la.pcrel relaxation for shared object
	Even in shared objects, la.got -> la.pcrel relaxation can still be
	performed for symbols with hidden visibility. For example, if a.c is:

	    extern int x;
	    int f() { return x++; }

	and b.c is:

	    int x = 114514;

	If compiling and linking with:

	    gcc -shared -fPIC -O2 -fvisibility=hidden a.c b.c

	Then the la.got in a.o should be relaxed to la.pcrel, and the resulted f
	should be like:

	    pcaddi  $t0, x
	    ldptr.w $a0, $t0, 0
	    addi.w  $t1, $a0, 1
	    stptr.w $t1, $t0, 0
	    ret

	Remove bfd_link_executable from the condition of la.got -> la.pcrel
	relaxation so this will really happen.  The SYMBOL_REFERENCES_LOCAL
	check is enough not to wrongly relax preemptable symbols (for e.g.
	when -fvisibility=hidden is not used).

	Note that on x86_64 this is also relaxed and the produced code is like:

	    lea x(%rip), %rdx
	    mov (%rdx), %rax
	    lea 1(%rax), %ecx
	    mov %ecx, (%rdx)
	    ret

	Tested by running ld test suite, bootstrapping and regtesting GCC with
	the patched ld, and building and testing Glibc with the patched ld.  No
	regression is observed.

	Yet another fix for mcore-sim (rotli)
	This came up testing the CRC optimization work from Mariam@RAU.
	Basically to optimize some CRC loops into table lookups or carryless
	multiplies, we may need to do a bit reflection, which on the mcore
	processor is done using a rotate instruction.

	Unfortunately the simulator implementation of rotates has the exact same
	problem as we saw with right shifts.  The input value may have been sign
	extended from 32 to 64 bits.  When we rotate the extended value, we get
	those sign extension bits and thus the wrong result.

	The fix is the same.  Rather than using a "long", use a uint32_t for the
	type of the temporary.  This fixes a handful of tests in the GCC testsuite:

	gdb/testsuite: another attempt to fix gdb.threads/thread-specific-bp.exp
	The gdb.threads/thread-specific-bp.exp test has been a little
	problematic, see commits:

	  Date:   Thu Mar 9 12:31:26 2023 +0100

	  Date:   Fri Nov 19 14:33:39 2021 +0100

	      [gdb/testsuite] Fix gdb.threads/thread-specific-bp.exp

	But I recently saw a test failure for that test, which looked like
	this:

	  ...
	  (gdb) PASS: gdb.threads/thread-specific-bp.exp: non_stop=on: thread 1 selected
	  continue -a
	  Continuing.

	  Thread 1 "thread-specific" hit Breakpoint 4, end () at /tmp/binutils-gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.threads/thread-specific-bp.c:29
	  29      }
	  (gdb) [Thread 0x7ffff7c5c700 (LWP 1552086) exited]
	  Thread-specific breakpoint 3 deleted - thread 2 no longer in the thread list.
	  FAIL: gdb.threads/thread-specific-bp.exp: non_stop=on: continue to end (timeout)
	  ...

	This only crops up (for me) when running on a loaded machine, and
	still only occurs sometimes.  I've had to leave the test running in a
	loop for 10+ minutes sometimes in order to see the failure.

	The problem is that we use gdb_test_multiple to try and match two
	patterns:

	  (1) The 'Thread-specific breakpoint 3 deleted ....' message, and
	  (2) The GDB prompt.

	As written in the test, we understand that these patterns can occur in
	any order, and we have a flag for each pattern.  Once both patterns
	have been seen then we PASS the test.

	The problem is that once expect has matched a pattern, everything up
	to, and including the matched text is discarded from the input
	buffer.  Thus, if the input buffer contains:

	  <PATTERN 2><PATTERN 1>

	Then expect will first try to match <PATTERN 1>, which succeeds, and
	then expect discards the entire input buffer up to the end of the
	<PATTERN 1>.  As a result, we will never spot <PATTERN 2>.

	Obviously we can't just reorder the patterns within the
	gdb_test_multiple, as the output can legitimately (and most often
	does) occur in the other order, in which case the test would mostly
	fail, and only occasionally pass!

	I think the easiest solution here is just to have the
	gdb_test_multiple contain two patterns, each pattern consists of the
	two parts, but in the alternative orders, thus, for a particular
	output configuration, only one regexp will match.  With this change in
	place, I no longer see the intermittent failure.

	Use function entry point record only for entry values
	PR28987 notes that optimized code sometimes shows the wrong
	value of variables at the entry point of a function, if some
	code was optimized away and the variable has multiple values
	stored in the debug info for this location.

	In this example:
	```
	void foo()
	{
	   int l_3 = 5, i = 0;
	   for (; i < 8; i++)
	       ;
	   test(l_3, i);
	}
	```
	When compiled with optimization, the entry point of foo is at
	the test() function call, since everything else is optimized
	away.
	The debug info of i looks like this:
	```
	(gdb) info address i
	Symbol "i" is multi-location:
	  Base address 0x140001600  Range 0x13fd41600-0x13fd41600: the constant 0
	  Range 0x13fd41600-0x13fd41600: the constant 1
	  Range 0x13fd41600-0x13fd41600: the constant 2
	  Range 0x13fd41600-0x13fd41600: the constant 3
	  Range 0x13fd41600-0x13fd41600: the constant 4
	  Range 0x13fd41600-0x13fd41600: the constant 5
	  Range 0x13fd41600-0x13fd41600: the constant 6
	  Range 0x13fd41600-0x13fd41600: the constant 7
	  Range 0x13fd41600-0x13fd4160f: the constant 8
	(gdb) p i
	$1 = 0
	```

	Currently, when at the entry point of a function, it will
	always show the initial value (here 0), while the user would
	expect the last value (here 8).
	This logic was introduced for showing the entry-values of
	function arguments if they are available, but for some
	reason this was added for non-entry-values as well.

	One of the tests of amd64-entry-value.exp shows the same
	problem for function arguments, if you "break stacktest"
	in the following example, you stop at this line:
	```
	124     static void __attribute__((noinline, noclone))
	125     stacktest (int r1, int r2, int r3, int r4, int r5, int r6, int s1, int s2,
	126                double d1, double d2, double d3, double d4, double d5, double d6,
	127                double d7, double d8, double d9, double da)
	128     {
	129       s1 = 3;
	130       s2 = 4;
	131       d9 = 3.5;
	132       da = 4.5;
	133 ->    e (v, v);
	134     asm ("breakhere_stacktest:");
	135       e (v, v);
	136     }
	```
	But `bt` still shows the entry values:
	```
	s1=s1@entry=11, s2=s2@entry=12, ..., d9=d9@entry=11.5, da=da@entry=12.5
	```

	I've fixed this by only using the initial values when
	explicitely looking for entry values.

	Now the local variable of the first example is as expected:
	```
	(gdb) p i
	$1 = 8
	```

	And the test of amd64-entry-value.exp shows the expected
	current and entry values of the function arguments:
	```
	s1=3, s1@entry=11, s2=4, s2@entry=12, ..., d9=3.5, d9@entry=11.5, da=4.5, da@entry=12.5
	```

	Also adjust obj_elf_ident() to invoke the hook after all section

	As noted in the context of d53e6b98a259 ("x86/Intel: correct disassembly
	of fsub*/fdiv*") there's no such thing as Intel syntax without Intel
	mnemonics. Enforce this on the assembler side, and disentangle command
	line option handling on the disassembler side accordingly.

	As a result in the opcode table specifying ATTMnemonic|ATTSyntax becomes
	redundant with just ATTMnemonic. Drop the now meaningless ATTSyntax and
	remove the then no longer accessible templates.

	Of course, this works just fine as option_def::var_address is a union,

	But it doesn't hurt to be correct, so fixed in this commit.

	The other test, arm-pseudo-unwind-legacy, tests the special case where

	gdb: read pseudo register through frame
	Change gdbarch_pseudo_register_read_value to take a frame instead of a
	regcache.  The frame (and formerly the regcache) is used to read raw
	registers needed to make up the pseudo register value.  The problem with
	using the regcache is that it always provides raw register values for
	the current frame (frame 0).

	Let's say the user wants to read the ebx register on amd64.  ebx is a pseudo
	register, obtained by reading the bottom half (bottom 4 bytes) of the
	rbx register, which is a raw register.  If the currently selected frame
	is frame 0, it works fine:

	    (gdb) frame 0
	    #0  break_here_asm () at /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.arch/amd64-pseudo-unwind-asm.S:36
	    36      in /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.arch/amd64-pseudo-unwind-asm.S
	    (gdb) p/x $ebx
	    $1 = 0x24252627
	    (gdb) p/x $rbx
	    $2 = 0x2021222324252627

	But if the user is looking at another frame, and the raw register behind
	the pseudo register has been saved at some point in the call stack, then
	we get a wrong answer:

	    (gdb) frame 1
	    #1  0x000055555555517d in caller () at /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.arch/amd64-pseudo-unwind-asm.S:56
	    56      in /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.arch/amd64-pseudo-unwind-asm.S
	    (gdb) p/x $ebx
	    $3 = 0x24252627
	    (gdb) p/x $rbx
	    $4 = 0x1011121314151617

	Here, the value of ebx was computed using the value of rbx in frame 0
	(through the regcache), it should have been computed using the value of
	rbx in frame 1.

	In other to make this work properly, make the following changes:

	 - Make dwarf2_frame_prev_register return nullptr if it doesn't know how
	   to unwind a register and that register is a pseudo register.
	   Previously, it returned `frame_unwind_got_register`, meaning, in our
	   example, "the value of ebx in frame 1 is the same as the value of ebx
	   in frame 0", which is obviously false.  Return nullptr as a way to
	   say "I don't know".

	 - In frame_unwind_register_value, when prev_register (for instance
	   dwarf2_frame_prev_register) returns nullptr, and we are trying to
	   read a pseudo register, try to get the register value through
	   gdbarch_pseudo_register_read_value or gdbarch_pseudo_register_read.
	   If using gdbarch_pseudo_register_read, the behavior is known to be
	   broken.  Implementations should be migrated to use
	   gdbarch_pseudo_register_read_value to fix that.

	 - Change gdbarch_pseudo_register_read_value to take a frame_info
	   instead of a regcache, update implementations (aarch64, amd64, i386).
	   In i386-tdep.c, I made a copy of i386_mmx_regnum_to_fp_regnum that
	   uses a frame instead of a regcache.  The version using the regcache
	   is still used by i386_pseudo_register_write.  It will get removed in
	   a subsequent patch.

	 - Add some helpers in value.{c,h} to implement the common cases of
	   pseudo registers: taking part of a raw register and concatenating
	   multiple raw registers.

	 - Update readable_regcache::{cooked_read,cooked_read_value} to pass the
	   current frame to gdbarch_pseudo_register_read_value.  Passing the
	   current frame will give the same behavior as before: for frame 0, raw
	   registers will be read from the current thread's regcache.

	Notes:

	 - I do not plan on changing gdbarch_pseudo_register_read to receive a
	   frame instead of a regcache. That method is considered deprecated.
	   Instead, we should be working on migrating implementations to use
	   gdbarch_pseudo_register_read_value instead.

	 - In frame_unwind_register_value, we still ask the unwinder to try to
	   unwind pseudo register values.  It's apparently possible for the
	   debug info to provide information about [1] pseudo registers, so we
	   want to try that first, before falling back to computing them
	   ourselves.

	gdb: change value_of_register and value_of_register_lazy to take the next frame
	Some functions related to the handling of registers in frames accept
	"this frame", for which we want to read or write the register values,
	while other functions accept "the next frame", which is the frame next
	to that.  The later is needed because we sometimes need to read register
	values for a frame that does not exist yet (usually when trying to
	unwind that frame-to-be).

	value_of_register and value_of_register_lazy both take "this frame",
	even if what they ultimately want internally is "the next frame".  This
	is annoying if you are in a spot that currently has "the next frame" and
	need to call one of these functions (which happens later in this
	series).  You need to get the previous frame only for those functions to
	get the next frame again.  This is more manipulations, more chances of
	mistake.

	I propose to change these functions (and a few more functions in the
	subsequent patches) to operate on "the next frame".  Things become a bit
	less awkward when all these functions agree on which frame they take.

	So, in this patch, change value_of_register_lazy and value_of_register
	to take "the next frame" instead of "this frame".  This adds a lot of
	get_next_frame_sentinel_okay, but if we convert the user registers API
	to also use "the next frame" instead of "this frame", it will get simple
	again.

	gdb: fix bugs in {get,put}_frame_register_bytes
	I found this only by inspection: the myaddr pointer in
	{get,put}_frame_register_bytes is reset to `buffer.data ()` at each
	iteration.  This means that we will always use the bytes at the
	beginning of `buffer` to read or write to the registers, instead of
	progressing in `buffer`.

	Fix this by re-writing the functions to chip away the beginning of the
	buffer array_view as we progress in reading or writing the data.

	These bugs was introduced almost 3 years ago [1], and yet nobody
	complained.  I'm wondering which architecture relies on that register
	"overflow" behavior (reading or writing multiple consecutive registers
	with one {get,put}_frame_register_bytes calls), and in which situation.
	I find these functions a bit dangerous, if a caller mis-calculates
	things, it could end up silently reading or writing to the next
	register, even if it's not the intent.

	If I could change it, I would prefer to have functions specifically made
	for that ({get,put}_frame_register_bytes_consecutive or something like
	that) and make {get,put}_frame_register_bytes only able to write within
	a single register (which I presume represents most of the use cases of
	the current {get,put}_frame_register_bytes).  If a caller mis-calculates
	things and an overflow occurs while calling
	{get,put}_frame_register_bytes, it would hit an assert.  The problem is
	knowing which callers rely on the overflow behavior and which don't.

	in the `copy(array_view, array_view)` function.  It also integrates well
	when connecting with other APIs already using gdb::array_view.

	Add some overloads of the methods using raw pointers to avoid having to
	change all call sites at once (which is both a lot of work and risky).

	I tried to do this change in small increments, but since many of these
	functions use each other, it ended up simpler to do it in one shot than
	having a lot of intermediary / transient changes.

	This change extends into gdbserver as well, because there is some part
	of the regcache interface that is shared.

	Changing the reg_buffer_common interface to use array_view caused some
	build failures in nat/aarch64-scalable-linux-ptrace.c.  That file
	currently "takes advantage" of the fact that
	reg_buffer_common::{raw_supply,raw_collect} operates on `void *`, which
	IMO is dangerous.  It uses raw_supply/raw_collect directly on
	uint64_t's, which I guess is fine because it is expected that native
	code will have the same endianness as the debugged process.  To
	accomodate that, add some overloads of raw_collect and raw_supply that
	work on uint64_t.

	This file also uses raw_collect and raw_supply on `char` pointers.
	Change it to use `gdb_byte` pointers instead.  Add overloads of
	raw_collect and raw_supply that work on `gdb_byte *` and make an
	array_view on the fly using the register's size.  Those call sites could
	be converted to use array_view with not much work, in which case these
	overloads could be removed, but I didn't want to do it in this patch, to
	avoid starting to dig in arch-specific code.

	During development, I inadvertently changed reg_buffer::raw_compare's
	behavior to not accept an offset equal to the register size.  This
	behavior (effectively comparing 0 bytes, returning true) change was
	caught by the AArch64 SME core tests.  Add a selftest to make sure that
	this raw_compare behavior is preserved in the future.

	gdb: simplify conditions in regcache::{read,write,raw_collect,raw_supply}_part
	Make a few simplifications in these functions.

	1. When checking if we need to do nothing, if the length is 0, we don't
	   need to do anything, regardless of the value of offset.  Remove the
	   offset check.

	2. When check if transferring the whole register, if the length is equal
	   to the register size, then we transfer the whole register, no need to
	   check the offset.  Remove the offset check.

	3. In the gdb_asserts, it is unnecessary to check for:

	     offset <= reg_size

	   given that right after we check for:

	     len >= 0 && offset + len <= reg_size

	   If `offset + len` is <= reg_size and len is >= 0, then necessarily
	   offset is <= reg_size.  Remove the `offset <= reg_size` check.

	gdb: use reg_buffer_common throughout gdbsupport/common-regcache.h
	Right now, gdbsupport/common-regcache.h contains two abstractons for a
	regcache.  An opaque type `regcache` (gdb and gdbserver both have their
	own regcache that is the concrete version of this) and an abstract base
	class `reg_buffer_common`, that is the base of regcaches on both sides.
	These abstractions allow code to be written for both gdb and gdbserver,
	for instance in the gdb/arch sub-directory.

	However, having two
	different abstractions is impractical.  If some common code has a regcache,
	and wants to use an operation defined on reg_buffer_common, it can't.
	It would be better to have just one.  Change all instances of `regcache
	*` in gdbsupport/common-regcache.h to be `reg_buffer_common *`, then fix
	fallouts.

	Implementations in gdb and gdbserver now need to down-cast (using
	gdb::checked_static_cast) from reg_buffer_common to their concrete
	regcache type.  Some of them could be avoided by changing free functions
	(like regcache_register_size) to be virtual methods on
	reg_buffer_common.  I tried it, it seems to work, but I did not include
	it in this series to avoid adding unnecessary changes.

	gdb: don't handle i386 k registers as pseudo registers
	I think that i386 k registers are raw registers, and therefore shouldn't
	be handled in the various functions handling pseudo registers.

	What tipped me off is the code in i386_pseudo_register_read_into_value:

	      else if (i386_k_regnum_p (gdbarch, regnum))
		{
		  regnum -= tdep->k0_regnum;

		  /* Extract (always little endian).  */
		  status = regcache->raw_read (tdep->k0_regnum + regnum, raw_buf);

	We take regnum (the pseudo register number we want to read), subtract
	k0_regnum, add k0_regnum, and pass the result to raw_read.  So we would
	end up calling raw_read with the same regnum as the function received
	which is supposedly a pseudo register number.

	Other hints are:

	 - The command `maint print raw-registers` shows the k registers.
	 - Printing $k0 doesn't cause i386_pseudo_register_read_into_value to be
	   called.
	 - There's code in i387-tdep.c to save/restore the k registers.

	Remove handling of the k registers from:

	 - i386_pseudo_register_read_into_value
	 - i386_pseudo_register_write
	 - i386_ax_pseudo_register_collect

	gdb/python: avoid use of _PyOS_ReadlineTState
	In python/py-gdb-readline.c we make use of _PyOS_ReadlineTState,
	however, this variable is no longer public in Python 3.13, and so GDB
	no longer builds.

	We are making use of _PyOS_ReadlineTState in order to re-acquire the
	Python Global Interpreter Lock (GIL).  The _PyOS_ReadlineTState
	variable is set in Python's outer readline code prior to calling the
	user (GDB) supplied readline callback function, which for us is
	gdbpy_readline_wrapper.  The gdbpy_readline_wrapper function is called
	without the GIL held.

	Instead of using _PyOS_ReadlineTState, I propose that we switch to
	calling PyGILState_Ensure() and PyGILState_Release().  These functions
	will acquire the GIL based on the current thread.  I think this should
	be sufficient; I can't imagine why we'd be running
	gdbpy_readline_wrapper on one thread on behalf of a different Python
	thread.... that would be unexpected I think.

	gdb: improve error reporting for 'save gdb-index'
	While making recent changes to 'save gdb-index' command I triggered
	some errors -- of the kind a user might be expected to trigger if they
	do something wrong -- and I didn't find GDB's output as helpful as it
	might be.

	For example:

	  $ gdb -q /tmp/hello.x
	  ...
	  (gdb) save gdb-index /non_existing_dir
	  Error while writing index for `/tmp/hello': mkstemp: No such file or directory.

	That the error message mentions '/tmp/hello', which does exist, but
	doesn't mention '/non_existing_dir', which doesn't is, I think,
	confusing.

	Also, I find the 'mkstemp' in the error message confusing for a user
	facing error.  A user might not know what mkstemp means, and even if
	they do, that it appears in the error message is an internal GDB
	detail.  The user doesn't care what function failed, but wants to know
	what was wrong with their input, and what they should do to fix
	things.

	Similarly, for a directory that does exist, but can't be written to:

	  (gdb) save gdb-index /no_access_dir
	  Error while writing index for `/tmp/hello': mkstemp: Permission denied.

	In this case, the 'Permission denied' might make the user thing there
	is a permissions issue with '/tmp/hello', which is not the case.

	After this patch, the new errors are:

	  (gdb) save gdb-index /non_existing_dir
	  Error while writing index for `/tmp/hello': `/non_existing_dir': No such file or directory.

	and:

	  (gdb) save gdb-index /no_access_dir
	  Error while writing index for `/tmp/hello': `/no_access_dir': Permission denied.

	we also have:

	  (gdb) save gdb-index /tmp/not_a_directory
	  Error while writing index for `/tmp/hello': `/tmp/not_a_directory': Is not a directory.

	I think these do a better job of guiding the user towards fixing the
	problem.

	I've added a new test that exercises all of these cases, and also
	checks the case where a user tries to use an executable that already
	contains an index in order to generate an index.  As part of the new
	test I've factored out some code from ensure_gdb_index (lib/gdb.exp)
	into a new proc (get_index_type), which I've then used in the new
	test.  I've confirmed that all the tests that use ensure_gdb_index
	still pass.

	During review it was pointed out that the testsuite proc
	have_index (lib/gdb.exp) is similar to the new get_index_type proc, so
	I've rewritten have_index to also use get_index_type, I've confirmed
	that all the tests that use have_index still pass.

	Nothing that worked correctly before this patch should give an error
	after this patch; I've only changed the output when the user was going
	to get an error anyway.

2023-12-12  Rui Ueyama  <rui314@gmail.com>

	RISC-V: Emit R_RISCV_RELAX for the la/lga pseudo instruction
	Some psABIs define a relaxation to turn a GOT load into a PC-relative
	address materialization.  For example, the AArch64's psABI allows
	adrp+ldr to be rewritten to nop+adr to eliminate the memory load.
	This patch is part of the effort to make such optimization possible
	for RISC-V.

	For RISC-V, we use the la assembly pseudo instruction to load a symbol
	address from the GOT. The pseudo instruction is expanded to auipc+ld.
	If the address loaded by the instruction pair is actually a PC-relative
	link-time constant, we want the linker to rewrite the instruction pair
	with auipc+addi.

	We can't rewrite all existing auipc+ld pairs with auipc+addi in the
	linker because there might be code that jumps to the middle of the
	instruction pair.  That should be extremely rare, if ever exists, but
	you can at least in theory write a program in assembly that jumps to
	the ld instruction of the instruction pair.  We need a marker to
	identify that an auipc+ld can be safely relaxed (i.e. they are emitted
	for la).

	This patch is to annotate R_RISCV_GOT_HI20 with R_RISCV_RELAX only
	when the relocation is emitted for the la pseudo instruction.  The
	linker will use it as a signal that the instruction pair can be safely
	relaxed.

	RISC-V: Resolve PCREL_HI20/LO12_I/S fixups with local symbols while `-mno-relax'
	In the scenario of generating .ko files, the kernel does not relax the .ko
	files.  However, due to the large amount of relax and local relocation
	information, this increases the size of the .ko files.  In this patch, it
	will finish the fixup of the local relocations while with `-mno-relax' option.
	This can reduce the size of the relocation table.

	The implemntation is based on the code from bfd/elfnn-riscv.c.  We probably

	just like what we did for the architecture parser.

	Besides, maybe not only pcrel_hi/lo12 relocation with local symbols can be

	Fix dynamic_cast
	PR29011 notes that dynamic_cast does not work correctly if

	wrongly point into the vtable of the derived class:
	```

	(gdb) p vl

	(gdb) p dynamic_cast<VirtualRight*>(vr)
	$12 = (VirtualRight *) 0x13fab89b0 <vtable for VirtualLeftRight+16>
	```

	For the cases where the dynamic_cast type is the same as the
	original type, it used the ARG value for the result, which in
	case of pointer types was already the dereferenced value.

	And the TEM value at the value address was created with the
	pointer/reference type, not the actual class type.

	With these fixed, the dynamic_cast results make more sense:

	RISC-V/gas: Clarify the definition of `relaxable' in md_apply_fix
	The `relaxable' in md_apply_fix means if the relocation can be relaxed or not
	in link-time generally.  We can use `.option relax/norelax' to enable/disable
	relaxations for some specific areas, so the value of `riscv_opts.relax'
	will be changed dynamically.  The `fixP->fx_tcbit' records the correct value
	of `riscv_opts.relax' for every relocation.  Therefore, set `relaxable' to
	`riscv_opts.relax' will cause unexpected behavior for the following case,

	.option norelax
	lla a1, foo1
	.option relax
	lla a2, foo2
	.option norelax
	lla a3, foo3

	For the current assembler, the final value of `riscv_opts.relax' is false, so

	Improve performance of the H8 simulator
	Running the H8 port through the GCC testsuite currently takes 4h 30m on my
	fastest server -- that's roughly 1.5hrs per multilib tested and many tests are
	disabled for various reasons.

	To put that 1.5hr/multilib in perspective, that's roughly 3X the time for other
	embedded targets.  Clearly something isn't working as well as it should.

	A bit of digging with perf shows that we're spending a crazy amount of time
	decoding instructions in the H8 simulator.  It's not hard to see why --
	basically we take a blob of instruction data, then try to match it to every
	instruction in the H8 opcode table starting at the beginning.  That table has
	~8000 entries (each different addressing mode is considered a different
	instruction in the table).

	Naturally my first thought was to sort the table and use a binary search to
	find the right entry.  That's made excessively complex due to the encoding on
	the H8.  Just getting the sort right would be much more complex than I'd
	consider advisable.

	Another thought was to build a mapping to the right entry for all the
	instructions that can be disambiguated based on the first nibble (4 bits) of
	instruction data and a mapping for those which can be disambiguated based on
	the first byte of instruction data.

	That seemed feasible until I realized that the H8/SX did some truly horrid
	things with encoding branches in the 0x4XYY opcode space.  It uses an "always
	zero" bit in the offset to encode new semantic information.  So we can't select
	on just 0x4X.  Ugh!

	We could always to a custom decoder.  I've done several through the years, they
	can be very fast.  But no way I can justify the time to do that.

	So what I settled on was to first sort the opcode table by the first nibble,
	then find the index of the first instruction for each nibble. Decoding uses
	that index to start its search.  This cuts the overall build/test by more than
	half.

	Next I adjusted the sort so that instructions that are not available on the
	current sub architecture are put at the end of the table.   This shaves another
	~15% off the total cycle time.

	The net of the two changes is on my fastest server we've gone from 4:30 to 1:40
	running the GCC testsuite.  Same test results before/after, of course.  It's
	still not fast, but it's a hell of a lot better.

	[gdb/tui] Show focus window in status line
	The focused window is highlighted by using active-border-kind instead of

	But if the focused window is the cmd window (which is an unboxed window), then

	on boxed windows, and then infer that the focus is on the unboxed window.

	gdb/testsuite: tighten up some end-of-line patterns
	Following on from the previous commit, I searched the testsuite for

	in most cases the <some pattern> could be replaced with "\r\n" though
	in the stabs test I've switched to using the multi_line proc as that
	seemed like a better choice.

	In gdb.ada/info_types.exp I did need to add an extra use of $eol as
	the previous pattern would match multiple newlines, and in this one
	place we were actually expecting to match multiple newlines.  The
	tighter pattern only matches a single newline, so we now need to be

	gdb/testsuite: fix gdb.ada/complete.exp timeout in READ1 mode
	While reviewing another patch I spotted a timeout in
	gdb.ada/complete.exp when testing in READ1 mode, e.g.:

	  $ make check-read1 TESTS="gdb.ada/complete.exp"
	  ...
	  FAIL: gdb.ada/complete.exp: complete break ada (timeout)
	  ...

	The problem is an attempt to match the entire output from GDB within a
	single gdb_test_multiple pattern, for a completion command that
	returns a large number of completions.

	This commit changes the gdb_test_multiple to process the output line
	by line.  I don't use the gdb_test_multiple -lbl option, as I've
	always found that option backward -- it checks for the \r\n at the
	start of each line rather than the end, I think it's much clearer to
	use '^' at the start of each pattern, and '\r\n' at the end, so that's
	what I've done here.

	.... Or I would, if this test didn't already define $eol as the end of
	line regexp ... except that $eol was set to '[\r\n]*', which isn't
	that helpful, so I've updated $eol to be just '\r\n' the actual end of
	line regexp.

	And now, the test passes without a timeout when using READ1.

	gdbserver: allow for general 'monitor set debug COMPONENT VALUE' use
	Building on the last commit, which added a general --debug=COMPONENT
	option to the gdbserver command line, this commit updates the monitor
	command to allow for general:

	  (gdb) monitor set debug COMPONENT off|on

	style commands.  Just like with the previous commit, the COMPONENT can
	be any one of all, threads, remote, event-loop, and correspond to the
	same set of global debug flags.

	While on the command line it is possible to do:

	  --debug=remote,event-loop,threads

	the components have to be entered one at a time with the monitor
	command.  I guess there's no reason why we couldn't allow component
	grouping within the monitor command, but (to me) what I have here
	seemed more in the spirit of GDB's existing 'set debug ...' commands.
	If people want it then we can always add component grouping later.

	Notice in the above that I use 'off' and 'on' instead of '0' and '1',
	which is what the 'monitor set debug' command used to use.  The 0/1
	can still be used, but I now advertise off/on in all the docs and help
	text, again, this feels more inline with GDB's existing boolean
	settings.

	I have removed the two existing monitor commands:

	  monitor set remote-debug 0|1
	  monitor set event-loop-debug 0|1

	These are replaced by:

	  monitor set debug remote off|on
	  monitor set debug event-loop off|on

	respectively.

	gdbserver: allow the --debug command line option to take a value
	Currently, gdbserver has the following command line options related to
	debugging output:

	  --debug
	  --remote-debug
	  --event-loop-debug

	This doesn't scale well.  If I want an extra debug component I need to
	add another command line flag.

	This commit changes --debug to take a list of components.

	The currently supported components are: all, threads, remote, and
	event-loop.  The 'threads' component represents the debug we currently
	get from the --debug option.  And if --debug is used without a
	component list then the threads component is assumed as the default.

	Currently the threads component actually includes a lot of output that
	is not really threads related.  In the future I'd like to split this
	up into some new, separate components.  But that is not part of this
	commit, or even this series.

	The special component 'all' does what you'd expect: enables debug
	output from all supported components.

	The component list is parsed left to write, and you can prefix a
	component with '-' to disable that component, so I can write:

	  target> gdbserver --debug=all,-event-loop

	to get debug for all components except the event-loop component.

	I've removed the existing --remote-debug and --event-loop-debug
	command line options, these are equivalent to --debug=remote and
	--debug=event-loop respectively, or --debug=remote,event-loop to
	enable both components.

	In this commit I've only update the command line options, in the next
	commit I'll update the monitor commands to support a similar

	gdb: fix GDB_DEBUG and GDBSERVER_DEBUG Makefile variables
	The gdb/testsuite/README file documents GDB_DEBUG and GDBSERVER_DEBUG
	flags, which can be passed to make in order to enable debugging within
	GDB or gdbserver respectively.

	However, when I do:

	  make check-gdb GDB_DEBUG=infrun

	I don't see the corresponding debug feature within GDB being enabled.
	Nor does:

	  make check-gdb GDBSERVER_DEBUG=debug  \
	       RUNTESTFLAGS="--target_board=native-extended-gdbserver"

	Appear to enable gdbserver debugging.

	I tracked this down to the GDB_DEBUG and GDBSERVER_DEBUG flags being
	missing from the TARGET_FLAGS_TO_PASS variable in gdb/Makefile.  This
	variable already contains lots of testing related flags, like
	RUNTESTFLAGS and TESTS, so I think it makes sense to add GDB_DEBUG and
	GDBSERVER_DEBUG here too.

	With this done, this debug feature is now working as expected.

	Use pretty printers for struct member stubs
	PR29079 shows that pretty printers can be used for an incomplete
	type (stub), but only when printing it directly, not if it's
	part of another struct:
	```
	(gdb) p s
	$1 = {pp m_i = 5}
	(gdb) p s2
	$2 = {m_s = <incomplete type>, m_l = 20}
	```

	The reason is simply that in common_val_print the check for stubs
	is before any pretty printer is tried.
	It works if the pretty printer is tried before the stub check:
	```
	(gdb) p s
	$1 = {pp m_i = 5}
	(gdb) p s2
	$2 = {m_s = {pp m_i = 10}, m_l = 20}

	[gdb/tui] Fix displaying main after resizing
	A TUI src window is displaying either:
	- the source for the current frame,
	- the source for main, or
	- the string "[ No Source Available ]".

	Since commit 03893ce67b5 ("[gdb/tui] Fix resizing of terminal to 1 or 2 lines")
	we're able to resize the TUI to 1 line without crashing.

	I noticed that if TUI is displaying main, and we resize to 1 line (destroying
	the src window) and then back to a larger terminal (reconstructing the src
	window), the TUI displays "[ No Source Available ]" instead of main.

	Fix this by moving the responsibility for showing main from tui_enable to
	tui_source_window_base::rerender.

	gdb: Guarantee that an SAL's end is right before the next statement
	When examining a failure that happens when testing
	gdb.python/py-symtab.c with clang, I noticed that it was going wrong
	because the test assumed that whenever we get an SAL, its end would
	always be right before statement in the line table. This is true for GCC
	compiled binaries, since gcc only adds statements to the line table, but
	not true for clang compiled binaries.

	This is the second time I run into a problem where GDB doesn't handle
	non-statement line table entries correctly. The other was eventually
	committed as 9ab50efc463ff723b8e9102f1f68a6983d320517: "gdb: fix until
	behavior with trailing !is_stmt lines", but that commit only changes the
	behavior for the 'until' command. In this patch I propose a more general
	solution, making it so every time we generate the SAL for a given pc, we
	set the end of the SAL to before the next statement or the first
	instruciton in the next line, instead of naively assuming that to be the
	case.

	With this new change, the edge case is removed from the processing of
	the 'until' command without regressing the accompanying test case, and
	no other regressions were observed in the testsuite.

	Add more 'step' tests to gdb.base/watchpoint.exp
	The test gdb.base/watchpoint.exp has a proc named 'test_stepping'
	which claims to "Test stepping and other mundane operations with
	watchpoints enabled".  It sets a watchpoint on ival2, performs an
	inferior function call (which is not at all mundane), and uses 'next',
	'until', and, finally, does a 'step'.

	However, that final 'step' command steps to (but not over/through) the
	line at which the assignment to ival2 takes place.  At no time while
	performing these operations is a watchpoint hit.

	This commit adds a test to see what happens when stepping over/through
	the assignment to ival2.  The watchpoint on ival2 should be triggered
	during this step.  I've added another 'step' to make sure that the
	correct statement is reached after performing the watchpoint-hitting
	step.

	After running the 'test_stepping' proc, gdb.base/watchpoint.exp does
	a clean_restart before doing further tests, so nothing depends upon
	'test_stepping' to stop at the particular statement at which it had
	been stopping.

	I've examined all tests which set watchpoints and step.  I haven't
	been able to identify a(nother) test case which tests what happens
	when stepping over/through a statement which triggers a watchpoint.
	Therefore, adding these new 'step' tests is testing something which
	hasn't being tested elsewhere.

	Always use expand_symtabs_matching in ada-lang.c
	The previous patch fixed the immediate performance problem with Ada
	name matching, by having a subset of matches call
	expand_symtabs_matching rather than expand_matching_symbols.  However,
	it seemed to me that expand_matching_symbols should not be needed at
	all.

	To achieve this, this patch changes ada_lookup_name_info::split_name
	to use the decoded name, rather than the encoded name.  In order to
	make this work correctly, a new decoded form is used: one that does
	not decode operators (this is already done) and also does not decode
	wide characters.  The latter change is done so that changes to the Ada
	source charset don't affect the DWARF index.

	With this in place, we can change ada-lang.c to always use
	expand_symtabs_matching rather than expand_matching_symbols.

	Improve performance of Ada name searches
	A user reported that certain operations -- like printing a large
	structure -- could be slow.  I tracked this down to
	ada-lang.c:map_matching_symbols taking an inordinate amount of time.
	Specifically, calls like the one to look for a parallel "__XVZ"
	variable, in ada_to_fixed_type_1, could result in gdb walking over all
	the entries in the cooked index over and over.

	Looking into this reveals that
	cooked_index_functions::expand_matching_symbols is not written
	efficiently -- it ignores its "ordered_compare" parameter.  While
	fixing this would be good, it turns out that this entire method isn't
	needed; so this series removes it.

	However, the deletion is not done in this patch.  This one, instead,
	fixes the immediate cause of the slowdown, by using
	objfile::expand_symtabs_matching when possible.  This approach is
	faster because it is more selective about which index entries to
	examine.

	Fix hardware watchpoints in replay mode
	Changes introduced by commit 9e8915c6cee5c37637521b424d723e990e06d597
	caused a regression that meant hardware watchpoint stops would not
	trigger in reverse execution or replay mode.  This was documented in
	PR breakpoints/21969.
	The problem is that record_check_stopped_by_breakpoint always overwrites
	record_full_stop_reason, thus loosing the TARGET_STOPPED_BY_WATCHPOINT
	value which would be checked afterwards.

	This commit fixes that by not overwriting the stop-reason in
	record_full_stop_reason if we're not stopped at a breakpoint.

	And the test for hw watchpoints in gdb.reverse/watch-reverse.exp actually
	tested sw watchpoints again, since "set can-use-hw-watchpoints 1"
	doesn't convert enabled watchpoints to use hardware.
	This is fixed by disabling said watchpoint while enabling hw watchpoints.

	possible to use hw watchpoints in restored recordings anyways.

	  Date:   Mon Dec 4 14:23:17 2023 +0000

	      gdb: Enable early init of thread pool size

	I am now seeing this assert from libstdc++:

	  /usr/include/c++/9/bits/stl_algo.h:3715: constexpr const _Tp& std::clamp(const _Tp&, const _Tp&, const _Tp&) [with _Tp = int]: Assertion '!(__hi < __lo)' failed.

	This may only be visible because I compile with:

	  -D_GLIBCXX_DEBUG=1 -D_GLIBCXX_DEBUG_PEDANTIC=1

	but I haven't checked.  The issue the assert is highlighting is real,
	and is caused by this block of code:

	  if (n_threads < 0)
	    {
	      const int hardware_threads = std::thread::hardware_concurrency ();
	      /* Testing in #29959 indicates that parallel efficiency drops between
	         n_threads=5 to 8.  Therefore, clamp the default value to 8 to avoid an
	         excessive number of threads in the pool on many-core systems.  */
	      const int throttle = 8;
	      n_threads = std::clamp (hardware_threads, hardware_threads, throttle);
	    }

	The arguments to std::clamp are VALUE, LOW, HIGH, but in the above, if
	we have more than 8 hardware threads available the LOW will be greater
	than the HIGH, which is triggering the assert I see above.

	I believe std::clamp is the wrong tool to use here.  Instead std::min
	would be a better choice; we want the smaller value of
	HARDWARE_THREADS or THROTTLE.  If h/w threads is 2, then we want 2,
	but if h/w threads is 16 we want 8, this is what std::min gives us.

	After this commit, I no longer see the assert.

	Fix breakpoints on symbols with multiple trampoline symbols
	On mingw targets it's possible that there are multiple trampoline
	symbols for __cxa_throw, in each module where a throw is done, but
	without a corresponding global symbol.
	Since commit 77f2120b200be6cabbf6f610942fc1173a8df6d3 they cancel each
	other out in search_minsyms_for_name, which makes it impossible to set
	a breakpoint there:

	(gdb) b __cxa_throw
	Function "__cxa_throw" not defined.
	Make breakpoint pending on future shared library load? (y or [n]) y
	Breakpoint 2 (__cxa_throw) pending.
	(gdb) c
	Continuing.
	[Inferior 1 (process 10004) exited with code 03]

	With catch throw it also doesn't work, and you don't even get an error
	message:

	(gdb) catch throw
	Catchpoint 2 (throw)
	(gdb) c
	Continuing.
	[Inferior 1 (process 5532) exited with code 03]
	(gdb)

	The fix is to simply ignore other trampoline symbols when looking for
	corresponding global symbols, and it's working as expected:

	(gdb) b __cxa_throw
	Breakpoint 2 at 0x13f091590 (2 locations)
	(gdb) c

	Fix two buglets in .debug_names dumping
	While working on gdb's .debug_names writer, I found a couple of small
	bugs in binutils .debug_names dumping.

	First, the DWARF spec (section 6.1.1.4.6 Name Table) says:

	    These two arrays are indexed starting at 1, [...]

	I think it is clearer for binutils to follow this, particularly
	because DW_IDX_parent refers to this number.

	Second, I think the handling of an empty hash table is slightly wrong.
	Currently the dumping code assumes there is always an array of hashes.
	However, section 6.1.1.4.5 Hash Lookup Table says:

	    The optional hash lookup table immediately follows the list of
	    type signatures.

	and then:

	    The hash lookup table is actually two separate arrays: an array of
	    buckets, followed immediately by an array of hashes.

	My reading of this is that the hash table as a whole is optional, and
	so the hashes will not exist in this case.  (This also makes sense
	because the hashes are not useful without the buckets anyway.)

	This patch fixes both of these problems.  FWIW I have some gdb patches
	in progress that change gdb both to omit the hash table and to use
	DW_IDX_parent.

	s390: Support for jump visualization in disassembly
	Add support for jump visualization for the s390 architecture in
	disassembly:

	objdump -d --visualize-jumps ...

	Annotate the (conditional) jump and branch relative instructions with
	information required for jump visualization:
	- jump: Unconditional jump / branch relative.
	- condjump: Conditional jump / branch relative.
	- jumpsr: Jump / branch relative to subroutine.

	Unconditional jump and branch relative instructions are annotated as
	jump.
	Conditional jump and branch relative instructions, jump / branch
	relative on count/index, and compare and jump / branch relative
	instructions are annotated as condjump.
	Jump and save (jas, jasl) and branch relative and save (bras, brasl)
	instructions are annotated as jumpsr (jump to subroutine).

	Provide instruction information required for jump visualization during
	disassembly.
	The instruction type is provided after determining the opcode.
	For non-code it is set to dis_noninsn. Otherwise it defaults to
	dis_nonbranch. No annotation is done for data reference instructions
	(i.e. instruction types dis_dref and dis_dref2). Note that the
	instruction type needs to be provided before printing of the
	instruction, as it is used in print_address_func() to translate the
	argument value into an address if it is assumed to be a PC-relative
	offset. Note that this is never the case on s390, as
	print_address_func() is only called with addresses and never with
	offsets.
	The target of the (conditional) jump and branch relative instructions
	is provided during print, when the PC relative operand is decoded.

	include/

	gdb: Enable early init of thread pool size
	This commit enables the early initialization commands (92e4e97a9f5) to
	modify the number of threads used by gdb's thread pool.

	The motivation here is to prevent gdb from spawning a detrimental number
	of threads on many-core systems under environments with restrictive
	ulimits.

	With gdb before this commit, the thread pool takes the following sizes:

	1. Thread pool size is initialized to 0.

	2. After the maintenance commands are defined, the thread pool size is
	set to the number of system cores (if it has not already been set).

	3. Using early initialization commands, the thread pool size can be
	changed using "maint set worker-threads".

	4. After the first prompt, the thread pool size can be changed as in the
	previous step.

	Therefore after step 2. gdb has potentially launched hundreds of threads
	on a many-core system.

	After this change, step 2 and 3 are reversed so there is an opportunity
	to set the required number of threads without needing to default to the
	number of system cores first.

	There does exist a configure option (added in 261b07488b9) to disable
	multithreading, but this does not allow for an already deployed gdb to
	be configured.

	Additionally, the default number of worker threads is clamped at eight
	to control the number of worker threads spawned on many-core systems.
	This value was chosen as testing recorded on bugzilla issue 29959
	indicates that parallel efficiency drops past this point.

	GDB built with GCC 13.

	No test suite regressions detected. Compilers: GCC, ACfL, Intel, Intel
	LLVM, NVHPC; Platforms: x86_64, aarch64.

	The scenario that interests me the most involves preventing GDB from
	spawning any worker threads at all. This was tested by counting the
	number of clones observed by strace:

	    strace -e clone,clone3 gdb/gdb -q \
	    --early-init-eval-command="maint set worker-threads 0" \
	    -ex q ./gdb/gdb |& grep --count clone

	The new test relies on "gdb: install CLI uiout while processing early
	init files" developed by Andrew Burgess. This patch will need pushing
	prior to this change.

	The clamping was tested on machines with both 16 cores and a single
	core.  "maint show worker-threads" correctly reported eight and one
	respectively.

	gdb: install CLI uiout while processing early init files
	The next commit wants to use a 'show' command within an early
	initialisation file, despite these commands not being in the list of
	acceptable commands for use within an early initialisation file.

	The problem we run into is that the early initialisation files are
	processed before GDB has installed the top level interpreter.  The
	interpreter is responsible to installing the default uiout (accessed
	through current_uiout), and as a result code that depends on
	uiout (e.g. 'show' commands) will end up dereferencing a nullptr, and
	crashing GDB.

	I did consider moving the interpreter installation before the early
	initialisation, and this would work fine except for the new DAP
	interpreter, which relies on having Python available during its
	initialisation.  Which means we can't install the interpreter until
	after Python has been initialised, and the early initialisation
	handling has to occur before Python is setup -- that's the whole point
	of this feature (to allow customisation of how Python is setup).

	So, what I propose is that early within captured_main_1, we install a
	temporary cli_ui_out as the current_uiout.  This will remain in place
	until the top-level interpreter is installed, at which point the
	temporary will be replaced.

	What this means is that current_uiout will no longer be nullptr,
	instead, any commands within an early initialisation file that trigger
	output, will perform that output in a CLI style.

	I propose that we don't update the documentation for early
	initialisation files, we leave the user advice as being only 'set' and
	'source' commands are acceptable.  But now, if a user does try a
	'show' command, then instead of crashing, GDB will do something
	predictable.

	I've not added a test in this commit.  The next commit relies on this
	patch and will serve as a test.

	Fix detach bug when lwp has exited/terminated
	When using GDB on native linux, it can happen that, while attempting
	to detach an inferior, the inferior may have been exited or have been
	killed, yet still be in the list of lwps.  Should that happen, the
	assert in x86_linux_update_debug_registers in
	gdb/nat/x86-linux-dregs.c will trigger.  The line in question looks
	like this:

	  gdb_assert (lwp_is_stopped (lwp));

	For this case, the lwp isn't stopped - it's dead.

	The bug which brought this problem to my attention is one in which the
	pwntools library uses GDB to to debug a process; as the script is
	shutting things down, it kills the process that GDB is debugging and
	also sends GDB a SIGTERM signal, which causes GDB to detach all
	inferiors prior to exiting.  Here's a link to the bug:

	https://bugzilla.redhat.com/show_bug.cgi?id=2192169

	The following shell command mimics part of what the pwntools
	reproducer script does (with regard to shutting things down), but
	reproduces the bug much less reliably.  I have found it necessary to
	run the command a bunch of times before seeing the bug.  (I usually
	see it within 5-10 repetitions.)  If you choose to try this command,
	make sure that you have no running "cat" or "gdb" processes first!

	  cat </dev/zero >/dev/null & \
	  (sleep 5; (kill -KILL `pgrep cat` & kill -TERM `pgrep gdb`)) & \
	  sleep 1 ; \
	  gdb -q -iex 'set debuginfod enabled off' -ex 'set height 0' \
	      -ex c /usr/bin/cat `pgrep cat`

	So, basically, the idea here is to kill both gdb and cat at roughly
	the same time.  If we happen to attempt the detach before the process
	lwp has been deleted from GDB's (linux native) LWP data structures,
	then the assert will trigger.  The relevant part of the backtrace
	looks like this:

	My colleague, Andrew Burgess, has done some recent work on other
	problems with detach.  Upon hearing of this problem, he came up a test
	case which reliably reproduces the problem and tests for a few other
	problems as well.  In addition to testing detach when the inferior has
	terminated due to a signal, it also tests detach when the inferior has
	exited normally.  Andrew observed that the linux-native-only
	"checkpoint" command would be affected too, so the test also tests
	those cases when there's an active checkpoint.

	For the LWP exit / termination case with no checkpoint, that's handled
	via newly added checks of the waitstatus in detach_one_lwp in
	linux-nat.c.

	For the checkpoint detach problem, I chose to pass the lwp_info
	to linux_fork_detach in linux-fork.c.  With that in place, suitable
	tests were added before attempting a PTRACE_DETACH operation.

	I added a few asserts at the beginning of linux_fork_detach and
	modified the caller code so that the newly added asserts shouldn't
	trigger.  (That's what the 'pid == inferior_ptid.pid' check is about
	in gdb/linux-nat.c.)

	Lastly, I'll note that the checkpoint code needs some work with regard
	to background execution.  This patch doesn't attempt to fix that
	problem, but it doesn't make it any worse.  It does slightly improve
	the situation with detach because, due to the check noted above,
	linux_fork_detach() won't be called for the wrong inferior when there
	are multiple inferiors.  (There are at least two other problems with
	the checkpoint code when there are multiple inferiors.  See:
	https://sourceware.org/bugzilla/show_bug.cgi?id=31065)

	This commit also adds a new test,
	gdb.base/process-dies-while-detaching.exp.  Andrew Burgess is the
	primary author of this test case.  Its design is similar to that of
	gdb.threads/main-thread-exit-during-detach.exp, which was also written
	by Andrew.

	This test checks that GDB correctly handles several cases that can
	occur when GDB attempts to detach an inferior process.  The process
	can exit or be terminated (e.g.  via SIGKILL) prior to GDB's event
	loop getting a chance to remove it from GDB's internal data
	structures.  To complicate things even more, detach works differently
	when a checkpoint (created via GDB's "checkpoint" command) exists for
	the inferior.  This test checks all four possibilities: process exit
	with no checkpoint, process termination with no checkpoint, process
	exit with a checkpoint, and process termination with a checkpoint.

	Bail out of "attach" if a thread cannot be traced
	On Linux, threads are treated much like separate processes by the
	kernel.  In particular, it's possible to ptrace just a single thread.
	If gdb tries to attach to a multi-threaded inferior, where a non-main
	thread is already being traced (e.g., by strace), then gdb will get
	into an infinite loop attempting to attach.

	This patch fixes this problem by having the attach fail if ptrace
	fails to attach to any thread of the inferior.

	gdb: return when exceeding buffer size in regcache::transfer_regset
	regcache::transfer_regset iterates over an array of regcache_map_entry,
	transferring the registers (between regcache and buffer) described by
	those entries.  It stops either when it reaches the end of the
	regcache_map_entry array (marked by a null entry) or (it seems like the
	intent is) when it reaches the end of the buffer (in which case not all
	described registers are transferred).

	I said "seems like the intent is", because there appears to be a small
	bug.  transfer_regset is made of two loops:

	    foreach regcache_map_entry:
	      foreach register described by the regcache_map_entry:
	        if the register doesn't fit in the remainder of the buffer:
		  break

	        transfer register

	When stopping because we have reached the end of the buffer, the break
	only breaks out of the inner loop.

	This problem causes some failures when I run tests such as
	gdb.arch/aarch64-sme-core-3.exp (on AArch64 Linux, in qemu).  This is
	partly due to aarch64_linux_iterate_over_regset_sections failing to add
	a null terminator in its regcache_map_entry array, but I think there is
	still a problem in transfer_regset.

	The sequence to the crash is:

	 - The `regcache_map_entry za_regmap` object built in
	   aarch64_linux_iterate_over_regset_sections does not have a null
	   terminator.
	 - When the target does not have a ZA register,
	   aarch64_linux_collect_za_regset calls `regcache->collect_regset` with
	   a size of 0 (it's actually pointless, but still it should work).
	 - transfer_regset gets called with a buffer size of 0.
	 - transfer_regset detects that the register to transfer wouldn't fit in
	   0 bytes, so it breaks out of the inner loop.
	 - The outer loop tries to go read the next regcache_map_entry, but
	   there isn't one, and we start reading garbage.

	Obviously, this would get fixed by making
	aarch64_linux_iterate_over_regset_sections use a null terminator (which
	is what the following patch does).  But I think that when detecting that
	there is not enough buffer left for the current register,
	transfer_regset should return, not only break out of the inner loop.

	This is a kind of contrived scenario, but imagine we have these two
	regcache_map_entry objects:

	  - 2 registers of 8 bytes
	  - 2 registers of 4 bytes

	For some reason, the caller passes a buffer of 12 bytes.
	transfer_regset will detect that the second 8 byte register does not
	fit, and break out of the inner loop.  However, it will then go try the
	next regcache_map_entry.  It will see that it can fit one 4 byte
	register in the remaining buffer space, and transfer it from/to there.
	This is very likely not an expected behavior, we wouldn't expect to
	read/write this sequence of registers from/to the buffer.

	In this example, whether passing a 12 bytes buffer makes sense or
	whether it is a size computation bug in the caller, we don't know, but I
	think that exiting as soon as a register doesn't fit is the sane thing
	to do.

	gdb/testsuite: fix completion tests when using READ1
	The commit a3da2e7e550c4fe79128b5e532dbb90df4d4f418 has introduced
	regressions when testing using the READ1 mechanism. The reason for that
	is the new failure path in proc test_gdb_complete_tab_unique, which
	looks for GDB suggesting more than what the test inputted, but not the
	correct answer, followed by a white space. Consider the following case:

	int foo(int bar, int baz);

	Sending the command "break foo<tab>" to GDB will return

	break foo(int, int)

	which easily fits the buffer in normal testing, so everything works, but
	when reading one character at a time, the test will find the partial
	"break foo(int, " and assume that there was a mistake, so we get a
	spurious FAIL.

	That change was added because we wanted to avoid forcing a completion
	failure to fail through timeout, which it had to do because there is no
	way to verify that the output is done, mostly because when I was trying
	to solve a different problem I kept getting reading errors and testing
	completion was frustrating.

	This commit implements a better way to avoid that frustration, by first
	testing gdb's complete command and only if that passes we will test tab
	completion. The difference is that when testing with the complete
	command, we can tell when the output is over when we receive the GDB
	prompt again, so we don't need to rely on timeouts. With this, the
	change to test_gdb_complete_tab_unique has been removed as that test
	will only be run and fail in the very unlikely scenario that tab
	completion is different than command completion.

	The following changes were applied:

	* Zvkn and Zvks include now Zvkb instead of Zvbb.

	This patch implements these changes between the frozen and the

	[gdb/build] Fix adding -DNDEBUG to python flags of release build
	In gdb/configure the line:
	...
	    $development || tentative_python_cflags="$tentative_python_cflags -DNDEBUG"
	...
	intends to ensure that -DNDEBUG is added to the python flags of a release
	build.

	However, when building gdb-14-branch we have:
	...
	configure:22024: checking compiler flags for python code
	  ...
	configure:22047: result:  -fno-strict-aliasing -fwrapv
	...

	This is a regression since commit db6878ac553 ("Move sourcing of development.sh
	to GDB_AC_COMMON"), which introduced a reference before assignment:
	...
	    $development || tentative_python_cflags="$tentative_python_cflags -DNDEBUG"
	  ...
	. $srcdir/../bfd/development.sh
	...
	and consequently -DNDEBUG is never added.

	[ This was not obvious to me, but apparently evaluating an empty or undefined
	variable in this context is similar to using ':' or 'true', so the line is
	evaluated as:
	...
	    true || tentative_python_cflags="$tentative_python_cflags -DNDEBUG"
	... ]

	Fix this by moving GDB_AC_COMMON up in gdb/configure.ac, similar to how that
	was done for gdbserver/configure.ac in commit db6878ac553.

	[ Unfortunately, the move might introduce issues similar to the one we're
	fixing, and I'm not sure how to check for this.  Shellcheck doesn't detect
	this type of problem.  FWIW, I did run shellcheck (using arguments -xa, in the

	before and after and observed that the number of lines/words/chars in the

	As is already done in a couple of other similar cases, this patches
	disables hwcaps support for libiberty.

	RISC-V: Avoid updating state until symbol is found
	Currently objdump gets and updates the map state once per symbol. Updating the
	state (partiularly riscv_parse_subset) is expensive and grows quadratically
	since we iterate over all symbols. By deferring this until once we've found the
	symbol of interest, we can reduce the time to dump a 4k insn file of .norvc and
	.rvc insns from ~47 seconds to ~0.13 seconds.

	gdb/python: display errors from command completion
	This commit makes the gdb.Command.complete methods more verbose when
	it comes to error handling.

	Previous to this commit if any commands implemented in Python
	implemented the complete method, and if there were any errors
	encountered when calling that complete method, then GDB would silently
	hide the error and continue as if there were no completions.

	This makes is difficult to debug any errors encountered when writing
	completion methods, and encourages the idea that Python extensions can
	be broken, and GDB will just silently work around them.

	I don't think this is a good idea.  GDB should encourage extensions to
	be written correctly, and robustly, and one way in which GDB can (I
	think) support this, is by pointing out when an extension goes wrong.

	In this commit I've gone through the Python command completion code,
	and added calls to gdbpy_print_stack() or gdbpy_print_stack_or_quit()
	in places where we were either clearing the Python error, or, in some
	cases, just not handling the error at all.

	One thing I have not changed is in cmdpy_completer (py-cmd.c) where we
	process the list of completions returned from the Command.complete
	method; this routine includes a call to gdbpy_is_string to check a
	possible completion is a string, if not the completion is ignored.

	I was tempted to remove this check, attempt to complete each result to
	a string, and display an error if the conversion fails.  After all,
	returning anything but a string is surely a mistake by the extension
	author.

	However, the docs clearly say that only strings within the returned
	list will be considered as completions.  Anything else is ignored.  As
	such, and to avoid (what I think is pretty unlikely) breakage of
	existing code, I've retained the gdbpy_is_string check.

	After the gdbpy_is_string check we call python_string_to_host_string,
	if this call fails then I do now print the error, where before we
	ignored the error.  I think this is OK; if GDB thinks something is a
	string, but still can't convert it to a string, then I think it's OK
	to display the error in that case.

	Another case which I was a little unsure about was in
	cmdpy_completer_helper, and the call to PyObject_CallMethodObjArgs,
	which is when we actually call Command.complete.  Previously, if this
	call resulted in an exception then we would ignore this and just
	pretend there were no completions.

	Of all the changes, this is possibly the one with the biggest
	potential for breaking existing scripts, but also, is, I think, the
	most useful change.  If the user code is wrong in some way, such that
	an exception is raised, then previously the user would have no obvious
	feedback about this breakage.  Now GDB will print the exception for
	them, making it, I think, much easier to debug their extension.  But,
	if there is user code in the wild that relies on raising an exception
	as a means to indicate there are no completions .... well, that code
	is going to break after this commit.  I think we can live with this
	though, the exceptions means no completions thing was never documented
	behaviour.

	I also added a new error() call if the PyObject_CallMethodObjArgs call
	raises an exception.  This causes the completion mechanism within GDB
	to stop.  Within GDB the completion code is called twice, the first
	time to compute the work break characters, and then a second time to
	compute the actual completions.

	If PyObject_CallMethodObjArgs raises an exception when computing the
	word break character, and we print it by calling
	gdbpy_print_stack_or_quit(), but then carry on as if
	PyObject_CallMethodObjArgs had returns no completions, GDB will
	call the Python completion code again, which results in another call
	to PyObject_CallMethodObjArgs, which might raise the same exception
	again.  This results in the Python exception being printed twice.

	By throwing a C++ exception after the failed
	PyObject_CallMethodObjArgs call, the completion mechanism is aborted,
	and no completions are offered.  But importantly, the Python exception
	is only printed once.  I think this gives a much better user
	experience.

	I've added some tests to cover this case, as I think this is the most
	likely case that a user will run into.

	[gdb/tui] Use const std::string for string literals in tui-stack.c
	I noticed in gdb/tui/tui-stack.c a source-level micro-optimization where
	strlen with a string literal argument:
	...
	strlen ("bla")
	...
	is replaced with sizeof:
	...
	sizeof ("bla") - 1
	...

	The benefit of this is that the optimization is also done at O0, but the
	drawback is that it makes the expression harder to read.

	Use const std::string to encapsulate the string literals, and use
	std::string::size () instead.

	I tried making the string names (PROC_PREFIX, LINE_PREFIX, PC_PREFIX and
	SINGLE_KEY) lower-case, but that clashed with a pre-existing pc_prefix, so
	I've left them upper-case.

	Tested on x86_64-linux.

	libiberty, ld: Use x86 HW optimized sha1
	The following patch attempts to use x86 SHA ISA if available to speed
	up in my testing about 2.5x sha1 build-id processing (in my case on
	AMD Ryzen 5 3600) while producing the same result.
	I believe AArch64 has similar HW acceleration for SHA1, perhaps it
	could be added similarly.

	Note, seems lld uses BLAKE3 rather than md5/sha1.  I think it would be
	a bad idea to lie to users, if they choose --buildid=sha1, we should
	be using SHA1, not some other checksum, but perhaps we could add some other
	--buildid= styles and perhaps make one of the new the default.

	gdb/testsuite: add a new check-all-boards target
	The make-check-all.sh script (gdb/testsuite/make-check-all.sh) is
	great, it makes it super easy to run some test(s) using all the
	available board files.

	This commit aims to make this script even easier to access by adding a
	check-all-boards target to the GDB Makefile.  This new target checks
	for (and requires) a number of environment variables, so the target
	should be used like this:

	  make check-all-boards GDB_TARGET_USERNAME=remote-target \
	                        GDB_HOST_USERNAME=remote-host \
				TESTS="gdb.base/break.exp"

	Where GDB_TARGET_USERNAME and GDB_HOST_USERNAME are the user names
	that should be passed to the make-check-all.sh --target-user and
	--host-user command line options respectively.

	My personal intention is to set these variables in my environment, so
	all I'll need to do is:

	  make check-all-boards TESTS="gdb.base/break.exp"

	The make rule always passes --keep-results to the make-check-all.sh
	script, as I find that the most useful.  It's super frustrating to run
	the tests and realise you forgot that option and the results have been
	discarded.

	gdb/testsuite: log 'make check' command in make-check-all.sh
	I have been making more use of the make-check-all.sh script to run

	But one thing is pretty annoying.  When a test fails on some random
	board, I have to run make-check-all.sh with --verbose and --dry-run in
	order to see what RUNTESTFLAGS I should be using.

	I always run with --keep-results on, so, in this commit, I propose
	that, when --keep-results is on the 'make check' command will be
	written out to a file within the stored results directory, like:

	  check-all/BOARD_NAME/make-check.sh

	then, if I want to rerun a test, I can just:

	  sh check-all/BOARD_NAME/make-check.sh

	and the test will be re-run for me.

	gdb: generate dwarf-5 index identically as worker-thread count changes
	Similar to the previous commit, this commit ensures that the dwarf-5
	index files are generated identically as the number of worker-threads
	changes.

	Building the dwarf-5 index makes use of a closed hash table, the
	bucket_hash local within debug_names::build().  Entries are added to
	bucket_hash from m_name_to_value_set, which, in turn, is populated
	by calls to debug_names::insert() in write_debug_names.  The insert
	calls are ordered based on the entries within the cooked_index, and
	the ordering within cooked_index depends on the number of worker
	threads that GDB is using.

	My proposal is to sort each chain within the bucket_hash closed hash
	table prior to using this to build the dwarf-5 index.

	The buckets within bucket_hash will always have the same ordering (for
	a given GDB build with a given executable), and by sorting the chains
	within each bucket, we can be sure that GDB will see each entry in a
	deterministic order.

	I've extended the index creation test to cover this case.

	gdb: generate gdb-index identically regardless of work thread count
	It was observed that changing the number of worker threads that GDB
	uses (maintenance set worker-threads NUM) would have an impact on the
	layout of the generated gdb-index.

	The cause seems to be how the CU are distributed between threads, and
	then symbols that appear in multiple CU can be encountered earlier or
	later depending on whether a particular CU moves between threads.

	I certainly found this behaviour was reproducible when generating an
	index for GDB itself, like:

	  gdb -q -nx -nh -batch \
	      -eiex 'maint set worker-threads NUM' \
	      -ex 'save gdb-index /tmp/'

	And then setting different values for NUM will change the generated
	index.

	Now, the question is: does this matter?

	I would like to suggest that yes, this does matter.  At Red Hat we
	generate a gdb-index as part of the build process, and we would
	ideally like to have reproducible builds: for the same source,
	compiled with the same tool-chain, we should get the exact same output
	binary.  And we do .... except for the index.

	Now we could simply force GDB to only use a single worker thread when
	we build the index, but, I don't think the idea of reproducible builds
	is that strange, so I think we should ensure that our generated
	indexes are always reproducible.

	To achieve this, I propose that we add an extra step when building the
	gdb-index file.  After constructing the initial symbol hash table
	contents, we will pull all the symbols out of the hash, sort them,
	then re-insert them in sorted order.  This will ensure that the
	structure of the generated hash will remain consistent (given the same
	set of symbols).

	I've extended the existing index-file test to check that the generated
	index doesn't change if we adjust the number of worker threads used.
	Given that this test is already rather slow, I've only made one change
	to the worker-thread count.  Maybe this test should be changed to use
	a smaller binary, which is quicker to load, and for which we could
	then try many different worker thread counts.

	gdb: reduce size of generated gdb-index file
	I noticed in passing that out algorithm for generating the gdb-index
	file is incorrect.  When building the hash table in add_index_entry we

	large.  However, some of the incoming entries will be duplicates,
	which don't actually result in new items being added to the hash
	table.

	With an unmodified GDB, generating a gdb-index for GDB, I see a file
	size of 90M, with a hash usage (in the generated index file) of just
	2.6%.

	With a patched GDB, generating a gdb-index for the _same_ GDB binary,
	I now see a gdb-index file size of 30M, with a hash usage of 41.9%.

	This is a 67% reduction in gdb-index file size.

	Obviously, not every gdb-index file is going to see such big savings,
	however, the larger a program, and the more symbols that are
	duplicated between compilation units, the more GDB would over count,
	and so, over-grow the index.

	The gdb-index hash table we create has a minimum size of 1024, and
	then we grow the hash when it is 75% full, doubling the hash table at
	that time.  Given this, then we expect that either:

	  a. The hash table is size 1024, and less than 75% full, or
	  b. The hash table is between 37.5% and 75% full.

	I've include a test that checks some of these constraints -- I've not
	bothered to check the upper limit, and over full hash table isn't
	really a problem here, but if the fill percentage is less than 37.5%
	then this indicates that we've done something wrong (obviously, I also
	check for the 1024 minimum size).

	[gdb] Fix segfault in for_each_block, part 2
	The previous commit describes PR gdb/30547, a segfault when running test-case
	gdb.base/vfork-follow-parent.exp on powerpc64 (likewise on s390x).

	The root cause for the segmentation fault is that linux_is_uclinux gives an
	incorrect result: it returns true instead of false.

	So, why does linux_is_uclinux:
	...
	int
	linux_is_uclinux (void)
	{
	  CORE_ADDR dummy;

	  return (target_auxv_search (AT_NULL, &dummy) > 0
		  && target_auxv_search (AT_PAGESZ, &dummy) == 0);
	...
	return true?

	This is because ppc_linux_target_wordsize returns 4 instead of 8, causing
	ppc_linux_nat_target::auxv_parse to misinterpret the auxv vector.

	So, why does ppc_linux_target_wordsize:
	...
	int
	ppc_linux_target_wordsize (int tid)
	{
	  int wordsize = 4;

	  /* Check for 64-bit inferior process.	 This is the case when the host is
	     64-bit, and in addition the top bit of the MSR register is set.  */
	  long msr;

	  errno = 0;
	  msr = (long) ptrace (PTRACE_PEEKUSER, tid, PT_MSR * 8, 0);
	  if (errno == 0 && ppc64_64bit_inferior_p (msr))
	    wordsize = 8;

	  return wordsize;
	}
	...
	return 4?

	Specifically, we get this result because because tid == 0, so we get
	errno == ESRCH.

	The tid == 0 is caused by the switch_to_no_thread in
	handle_vfork_child_exec_or_exit:
	...
		  /* Switch to no-thread while running clone_program_space, so
		     that clone_program_space doesn't want to read the
		     selected frame of a dead process.  */
		  scoped_restore_current_thread restore_thread;
		  switch_to_no_thread ();

		  inf->pspace = new program_space (maybe_new_address_space ());
	...
	but moving the maybe_new_address_space call to before that gives us the
	same result.  The tid is no longer 0, but we still get ESRCH because the
	thread has exited.

	Fix this in handle_vfork_child_exec_or_exit by doing the
	maybe_new_address_space call in the context of the vfork parent.

	Tested on top of trunk on x86_64-linux and ppc64le-linux.
	Tested on top of gdb-14-branch on ppc64-linux.

	...
	or similar.

	The root cause for the segmentation fault is that linux_is_uclinux gives an
	incorrect result: it should always return false, given that we're running on a
	regular linux system, but instead it returns first true, then false.

	In more detail, the segmentation fault happens as follows:
	- a program space with an address space is created
	- a second program space is about to be created. maybe_new_address_space
	  is called, and because linux_is_uclinux returns true, maybe_new_address_space
	  returns false, and no new address space is created
	- a second program space with the same address space is created
	- a program space is deleted. Because linux_is_uclinux now returns false,
	  gdbarch_has_shared_address_space (current_inferior ()->arch ()) returns
	  false, and the address space is deleted
	- when gdb uses the address space of the remaining program space, we run into
	  the segfault, because the address space is deleted.

	Hardcoding linux_is_uclinux to false makes the test-case pass.

	We leave addressing the root cause for the following commit in this series.

	For now, prevent the segmentation fault by making the address space a refcounted
	object.

	This was already suggested here [1]:
	...
	A better solution might be to have the address spaces be reference counted
	...

	Tested on top of trunk on x86_64-linux and ppc64le-linux.
	Tested on top of gdb-14-branch on ppc64-linux.

	i386: Use a fallback XSAVE layout for remote targets
	If a target provides a target description including registers from the
	XSAVE extended region, but does not provide an XSAVE layout, use a
	fallback XSAVE layout based on the included registers.  This fallback
	layout matches GDB's behavior in earlier releases which assumes the
	layout from Intel CPUs.

	This fallback layout is currently only used for remote targets since
	native targets which support XSAVE provide an explicit layout derived
	from CPUID.

	[gdb/testsuite] Add boards/cc-with-index-cache.exp
	We have a target board cc-with-gdb-index that uses the gdb-add-index script to
	add a .gdb_index index to an exec.

	There is however an alternative way of adding a .gdb_index: the index-cache.

	Add a new target board cc-with-index-cache.

	This is not superfluous for two reasons:
	- there is functionality that gdb-add-index doesn't support, but the
	  index-cache does: the index-cache can add an index to an exec with a
	  .gnu_debugaltlink (note that when using the cc-with-gdb-index board this
	  case is quietly ignored), and
	- using the index-cache is excercised in only a few test-cases, and having
	  this target board extends the test coverage to the entire test suite.  This
	  is for instance relevant because the index-cache is written by a worker
	  thread in the background, so we can check more thoroughly for data races
	  (see PR symtab/30837).

	Fix bug in DAP handling of 'pause' requests
	While working on cancellation, I noticed that a DAP 'pause' request
	would set the "do not emit the continue" flag.  This meant that a
	subsequent request that should provoke a 'continue' event would
	instead suppress the event.

	I then tried writing a more obvious test case for this, involving an
	inferior call -- and discovered that gdb.events.cont does not fire for
	an inferior call.

	This patch installs a new event listener for gdb.events.inferior_call
	and arranges for this to emit continue and stop events when
	appropriate.  It also fixes the original bug, by adding a check to
	exec_and_expect_stop.

	gdb/python: handle completion returning a non-sequence
	GDB's Python API documentation for gdb.Command.complete() says:

	  The 'complete' method can return several values:
	     * If the return value is a sequence, the contents of the
	       sequence are used as the completions.  It is up to 'complete'
	       to ensure that the contents actually do complete the word.  A
	       zero-length sequence is allowed, it means that there were no
	       completions available.  Only string elements of the sequence
	       are used; other elements in the sequence are ignored.

	     * If the return value is one of the 'COMPLETE_' constants
	       defined below, then the corresponding GDB-internal completion
	       function is invoked, and its result is used.

	     * All other results are treated as though there were no
	       available completions.

	So, returning a non-sequence, and non-integer from a complete method
	should be fine; it should just be treated as though there are no
	completions.

	However, if I write a complete method that returns None, I see this
	behaviour:

	  (gdb) complete completefilenone x
	  Python Exception <class 'TypeError'>: 'NoneType' object is not iterable
	  warning: internal error: Unhandled Python exception
	  (gdb)

	Which is caused because we currently assume that anything that is not
	an integer must be iterable, and we call PyObject_GetIter on it.  When
	this call fails a Python exception is set, but instead of
	clearing (and therefore ignoring) this exception as we do everywhere
	else in the Python completion code, we instead just return with the
	exception set.

	In this commit I add a PySequence_Check call.  If this call returns
	false (and we've already checked the integer case) then we can assume
	there are no completion results.

	I've added a test which checks returning a non-sequence.

	RISC-V: drop leftover match_never() references
	Commit 27b33966b18e "RISC-V: disallow x0 with certain macro-insns"
	wasn't properly re-based over recent opcode table additions.

	x86: shrink opcode sets table
	Have i386-gen produce merely the offsets into i386_optab[]. Besides
	allowing to shrink the table even on 32-bit builds, this results in
	removing a level of indirection from the frequently accessed
	current_templates, in return for adding a level of indirection when
	looking up mnemonics (commonly happening just once per insn). Plus for
	PIE builds of gas it also reduces the number of relocations by about two
	thousand. Finally a somewhat ugly static variable can also be eliminated
	from i386_displacement().

	x86: also prefer VEX encoding over EVEX one for VCVTNEPS2BF16 when possible
	Deal with what 58bceb182740 ("x86: prefer VEX encodings over EVEX ones
	when possible") left out, for being slightly less straightforward.

	RISC-V: disallow x0 with certain macro-insns
	While for some of the macro insns using x0 is kind of okay, as they
	would merely resolve to a sequence of hint insns (and hence not cause
	misbehavior at runtime), several of them have the degenerate AUIPC
	followed by a load, store, or branch using other than the designated
	symbol as address and hence causing runtime issues. Refuse to assemble
	those, leveraging that the matching function so far wasn't really used
	for macro insns: NULL is now allowed, indicating a match (which imo is
	preferable over converting match_never() to match_always()), while
	other matching functions now (also) used for macro insns need to avoid
	calling match_opcode().

	Note that for LA the restriction is slightly too strict: In non-PIC mode
	using x0 would be okay-ish as per above (as it's just LLA there). Yet
	libopcodes doesn't know what mode gas is presently assembling for, so we
	want to err on the safe side.

	s390: Add brasl edge test cases from ESA to z/Architecture
	The ESA opcode test cases for IBM z900 contain a few edge cases. They
	exercise the brasl mnemonic with its largest allowed negative and
	positive offsets. Linux on zSeries in ESA mode executes in 31-bit
	addressing mode. Therefore the ESA test cases are assembled with -m31.
	In 31-bit addressing mode the address computation using those large
	offsets wraps, which is correctly reflected in the disassembly.

	Linux on Z in z/Architecture mode executes in 64-bit addressing mode.
	Therefore the z/Architecture (zarch) test cases are assembled with -m64.
	In 64-bit addressing mode the address computation using those large
	offsets does not necessarily wrap.

	s390: Position independent verification of relative addressing
	Opcode test cases for z/Architecture instructions that use relative
	addressing contained hardcoded offsets in the test verification
	patterns. Inserting or reordering of instructions into those test cases
	therefore required updating of those hardcoded offsets.

	Use regular expressions with backreferences to verify results of test
	cases containing instructions with relative addressing. This makes the
	verification position independent.

	Fix build with GCC 7.5
	A recent change to 'struct field' caused a build failure with GCC
	7.5.0, as reported by Tom de Vries:

	/data/vries/gdb/src/gdb/gdbtypes.h:721:51: error:
	‘field::m_accessibility’ is too small to hold all values of ‘enum
	class accessibility’ [-Werror]
	   ENUM_BITFIELD (accessibility) m_accessibility : 2;
	                                                   ^

	Mark Wielaard pointed out that this was a GCC bug:
	https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51242

	This patch works around the bug by changing several members not to be
	bitfields.  It reduces the size of the enum's underlying type,
	instead.

	I also changed m_bitsize to no longer be a bitfield -- that was done
	for packing reasons in ancient times, but with m_accessibility not
	being a bitfield, this no longer matters.

	I removed fn_field::dummy.  In earlier times it was somewhat normal in
	gdb to have these dummy fields to keep track of any available padding.
	However, since the advent of "ptype/o", there doesn't seem to be any
	need for this.

	This patch does not change the size of struct field, fn_field, or
	decl_field on 64-bit hosts.

	Fix AIX thr!= NULL assertion failure during fork.
	In AIX, while we followed the child process and detach on fork was on we hit thr!= NULL assertion failure.

	The reason for the same was GDB core trying to switch to a child thread with tid not set that does not
	exist, since child's ptid was changed to ptid_t (pid, 0, tid) in sync_threadlists() as it was threaded.

	The way this happened was when a new child process is born, its object file will be loaded, calling the new_objfile ()
	in aix-thread.c file from clone_program_space, which is
	called from within follow_fork_inferior. Therefore it end ups syncing threadlists via pd_update ().

	This patch is a fix for the same where pd_update () is called in the wait () or in update_thread_list() hook only.

	[gdb/tui] Fix resizing of terminal to 1 or 2 lines
	When starting TUI in a terminal with 3 lines:
	...
	$ echo $LINES
	3
	$ gdb -q -tui
	...
	and resizing the terminal to 2 lines we run into a segfault.

	The problem is that for the source window:
	- the minimum height is 3 (the default), but
	- the maximum height is only 2 because there are only 2 lines.

	This discrepancy eventually leads to a call to newwin in make_window with:
	...
	(gdb) p height
	$1 = 3
	(gdb) p width
	$2 = 56
	(gdb) p y
	$3 = -1
	(gdb) p x
	$4 = 0
	...
	which results in a nullptr.

	This violates the assumption here in tui_apply_current_layout:
	....
	  /* Get the new list of currently visible windows.  */
	  std::vector<tui_win_info *> new_tui_windows;
	  applied_layout->get_windows (&new_tui_windows);
	...
	that get_windows only returns visible windows, which leads to tui_windows
	holding a dangling pointer, which results in the segfault.

	Fix this by:
	- making sure get_windows only returns visible windows, and
	- detecting the situation and dropping windows from the layout if
	  there's no room for them.

	Tested on x86_64-linux.

	The problem is that for the command window:

	(gdb) p y
	$3 = -1
	(gdb) p x
	$4 = 0
	(gdb)
	...
	which results in a nullptr, which eventually triggers the assert.

	The easiest way to fix this is to change the minimum height of the command
	window to 1.  However, that would also change behaviour for the case that the
	screen size is 3 lines or more.  For instance, in gdb.tui/winheight.exp the
	number of lines in the terminal is 24, and the test-case checks that the user
	cannot increase the source window height to the point that the command window
	height would be less than 3.

	Fix this by calculating the minimum height of the command window as follows:
	- the default (3) if max_height () allows it, and
	- max_height () otherwise.

	[gdb/testsuite] Fix spurious FAILs with examine-backward.exp, again
	Commit 59a561480d5 ("Fix spurious FAILs with examine-backward.exp") describes
	the problem that:
	...
	The test case examine-backward.exp issues the command "x/-s" after the end
	of the first string in TestStrings, but without making sure that this
	string is preceded by a string terminator.  Thus GDB may spuriously print
	some random characters from before that string, and then the test fails.
	...

	The commit fixes the problem by adding a Barrier variable before the TestStrings
	variable:
	...
	+const char Barrier[] = { 0x0 };
	 const char TestStrings[] = {
	...

	There is however no guarantee that Barrier is placed immediately before
	TestStrings.

	Before recent commit 169fe7ab54b ("Change gdb.base/examine-backwards.exp for
	AIX.") on x86_64-linux, I see:
	...
	0000000000400660 R Barrier
	0000000000400680 R TestStrings
	...

	So while the Barrier variable is the first before the TestStrings variable,
	it's not immediately preceding TestStrings.

	After commit 169fe7ab54b:
	...
	0000000000402259 B Barrier
	0000000000402020 D TestStrings
	...
	they're not even in the same section anymore.

	Fix this reliably by adding the zero in the array itself:
	...
	char TestStringsBase[] = {
	  0x0,
	  ...
	};
	char *TestStrings = &TestStringsBase[1];
	...
	and do likewise for TestStringsH and TestStringsW.

	...
	(gdb) PASS: $exp: execve: syscall(s) execve appears in 'info breakpoints'

	Cannot access memory at address 0xf77c6a7c^M
	(gdb) FAIL: $exp: execve: syscall execve has returned
	...

	The memory error is thrown by arm_linux_get_syscall_number, when doing:
	...
	     /* PC gets incremented before the syscall-stop, so read the
	         previous instruction.  */
	      unsigned long this_instr =
	        read_memory_unsigned_integer (pc - 4, 4, byte_order_for_code);
	...

	The reason for the error is that we're stopped at the syscall exit of syscall
	execve, and the pc is at the first insn of the new exec, which also happens to
	be the first insn in the code segment, so consequently we cannot read the
	previous insn.

	Fix this by detecting the situation by looking at the register state, similar
	to what is done in aarch64_linux_get_syscall_number.

	Furthermore, catch the memory error by using safe_read_memory_unsigned_integer
	and return -1 instead, matching the documented behaviour of
	arm_linux_get_syscall_number.

	Finally, rather than using a hardcoded constant 11, introduce an ad-hoc
	arm_sys_execve.

	This binary causes a segfault in GDB.  GDB is trying to write the .dynamic
	section into memory allocated on the stack with alloca().  However, the
	allocation silently fails and the subsequent access to the memory is
	causing the segfault. (On my node at least.)

	Stack allocation is a bad idea for something of variable size that GDB has
	no control over.  So I changed the code to heap allocation.

	In addition, I changed the type of sect_size to the type that bfd actually
	returns.

	libctf: adding CU mappings should be idempotent
	When CTF finds conflicting types, it usually shoves each definition
	into a CTF dictionary named after the compilation unit.

	The intent of the obscure "cu-mapped link" feature is to allow you to
	implement custom linkers that shove the definitions into other, more
	coarse-grained units (say, one per kernel module, even if a module consists
	of more than one compilation unit): conflicting types within one of these
	larger components are hidden from name lookup so you can only look up (an
	arbitrary one of) them by name, but can still be found by chasing type graph
	links and are still fully deduplicated.

	You do this by calling
	ctf_link_add_cu_mapping (fp, "CU name", "bigger lump name"), repeatedly,
	with different "CU name"s: the ctf_link() following that will put all
	conflicting types found in "CU name"s sharing a "bigger lump name" into a
	child dict in an archive member named "bigger lump name".

	So it's clear enough what happens if you call it repeatedly with the same
	"bigger lump name" more than once, because that's the whole point of it: but
	what if you call it with the same "CU name" repeatedly?

	ctf_link_add_cu_mapping (fp, "CU name", "bigger lump name");
	ctf_link_add_cu_mapping (fp, "CU name", "other name");

	This is meant to be the same as just doing the second of these, as if the
	first was never called.  Alas, this isn't what happens, and what you get is
	instead a bit of an inconsistent mess: more or less, the first takes
	precedence, which is the exact opposite of what we wanted.

	Fix this to work the right way round.

	(I plan to add support for CU-mapped links to GNU ld, mainly so that we can
	properly *test* this machinery.)

	libctf/ChangeLog:

		* ctf-link.c (ctf_create_per_cu): Note the behaviour of
		repeatedly adding FROMs.

	      gdb: fix reread_symbols when an objfile has target: prefix

	In this commit I update reopen_exec_file to correctly handle
	executables with a target: prefix.  Before this commit we used the
	system 'stat' call, which obviously isn't going to work for files with
	a target: prefix (files located on a possibly remote target machine).

	By switching to bfd_stat we will use remote fileio to stat the remote
	files, which means we should now correctly detect changes in a remote
	executable.

	The program_space::ebfd_mtime variable, with which we compare the
	result of bfd_stat is set with a call to bfd_get_mtime, which in turn
	calls bfd_stat, so comparing to the result of calling bfd_stat makes
	sense (I think).

	As I discussed in the commit f2c4f78c813a, if a BFD is an in-memory
	BFD, then calling bfd_stat will always return 0, while bfd_get_mtime
	will always return the time at which the BFD was created.  As a result
	comparing the results will always show the file having changed.

	I don't believe that GDB can set the main executable to an in-memory
	BFD object, so, in this commit, I simply assert that the executable is
	not in-memory.  If this ever changes then we would need to decide how
	to handle this case -- always reload, or never reload.  The assert
	doesn't appear to trigger for our current test suite.

	gdb: move all bfd_cache_close_all calls in gdb_bfd.c
	In the following commit I ran into a problem.  The next commit aims to
	improve GDB's handling of the main executable being a file on a remote
	target (i.e. one with a 'target:' prefix).

	To do this I have replaced a system 'stat' call with a bfd_stat call.

	However, doing this caused a regression in gdb.base/attach.exp.

	The problem is that the bfd library caches open FILE* handles for bfd
	objects that it has accessed, which is great for short-lived, non
	interactive programs (e.g. the assembler, or objcopy, etc), however,
	for GDB this caching causes us a problem.

	If we open the main executable as a bfd then the bfd library will
	cache the open FILE*.  If some time passes, maybe just sat at the GDB
	prompt, or with the inferior running, and then later we use bfd_stat
	to check if the underlying, on-disk file has changed, then the bfd
	library will actually use fstat on the underlying file descriptor.
	This is of course slightly different than using system stat on with
	the on-disk file name.

	If the on-disk file has changed then system stat will give results for
	the current on-disk file.  But, if the bfd cache is still holding open
	the file descriptor for the original on-disk file (from before the
	change) then fstat will return a result based on the original file,
	and so show no change as having happened.

	This is a known problem in GDB, and so far this has been solved by
	scattering bfd_cache_close_all() calls throughout GDB.  But, as I
	said, in the next commit I've made a change and run into a
	problem (gdb.base/attach.exp) where we are apparently missing a
	bfd_cache_close_all() call.

	Now I could solve this problem by adding a bfd_cache_close_all() call
	before the bfd_stat call that I plan to add in the next commit, that
	would for sure solve the problem, but feels a little crude.

	Better I think would be to track down where the bfd is being opened
	and add a corresponding bfd_cache_close_all() call elsewhere in GDB
	once we've finished doing whatever it is that caused us to open the
	bfd in the first place.

	This second solution felt like the better choice, so I tracked the
	problem down to elf_locate_base and fixed that.  But that just exposed
	another problem in gdb_bfd_map_section which was also re-opening the
	bfd, so I fixed this (with another bfd_cache_close_all() call), and
	that exposed another issue in gdbarch_lookup_osabi... and at this
	point I wondered if I was approaching this problem the wrong way...

	.... And so, I wonder, is there a _better_ way to handle these
	bfd_cache_close_all() calls?

	I see two problems with the current approach:

	  1. It's fragile.  Folk aren't always aware that they need to clear
	  the bfd cache, and this feels like something that is easy to
	  overlook in review.  So adding new code to GDB can innocently touch
	  a bfd, which populates the cache, which will then be a bug that can
	  lie hidden until an on-disk file just happens to change at the wrong
	  time ... and GDB fails to spot the change.  Additionally,

	  2. It's in efficient.  The caching is intended to stop the bfd
	  library from continually having to re-open the on-disk file.  If we
	  have a function that touches a bfd then often that function is the
	  obvious place to call bfd_cache_close_all.  But if a single GDB
	  command calls multiple functions, each of which touch the bfd, then
	  we will end up opening and closing the same on-disk file multiple
	  times.  It feels like we would be better postponing the
	  bfd_cache_close_all call until some later point, then we can benefit
	  from the bfd cache.

	So, in this commit I propose a new approach.  We now clear the bfd
	cache in two places:

	  (a) Just before we display a GDB prompt.  We display a prompt after
	  completing a command, and GDB is about to enter an idle state
	  waiting for further input from the user (or in async mode, for an
	  inferior event).  If while we are in this idle state the user
	  changes the on-disk file(s) then we would like GDB to notice this
	  the next time it leaves its idle state, e.g. the next time the user
	  executes a command, or when an inferior event arrives,

	  (b) When we resume the inferior.  In synchronous mode, resuming the
	  inferior is another time when GDB is blocked and sitting idle, but
	  in this case we don't display a prompt.  As with (a) above, when an
	  inferior event arrives we want GDB to notice any changes to on-disk
	  files.

	It turns out that there are existing observers for both of these
	cases (before_prompt and target_resumed respectively), so my initial
	thought was that I should attach to these observers in gdb_bfd.c, and
	in both cases call bfd_cache_close_all().

	And this does indeed solve the gdb.base/attach.exp problem that I see
	with the following commit.

	However, I see a problem with this solution.

	Both of the observers I'm using are exposed through the Python API as
	events that a user can hook into.  The user can potentially run any
	GDB command (using gdb.execute), so Python code might end up causing
	some bfds to be reopened, and inserted into the cache.

	To solve this one solution would be to add a bfd_cache_close_all()
	call into gdbpy_enter::~gdbpy_enter().  Unfortunately, there's no
	similar enter/exit object for Guile, though right now Guile doesn't
	offer the same event API, so maybe we could just ignore that
	problem... but this doesn't feel great.

	So instead, I think a better solution might be to not use observers
	for the bfd_cache_close_all() calls.  Instead, I'll call
	bfd_cache_close_all() directly from core GDB after we've notified the
	before_prompt and target_resumed observers, this was we can be sure
	that the cache is cleared after the observers have run, and before GDB
	enters an idle state.

	This commit also removes all of the other bfd_cache_close_all() calls
	from GDB.  My claim is that these are no longer needed.

	gdb/record: print frame information when exiting a recursive call
	Currently,  when GDB is reverse stepping out of a function into the same
	function due to a recursive call, it doesn't print frame information, as
	reported by PR record/29178. This happens because when the inferior
	leaves the current frame, GDB decides to refresh the step information,
	clobbering the original step_frame_id, making it impossible to figure
	out later on that the frame has been changed.

	This commit changes GDB so that, if we notice we're in this exact
	situation, we won't refresh the step information.

	Because of implementation details, this change can cause some debug
	information to be read when it normally wouldn't before, which showed up
	as a regression on gdb.dwarf2/dw2-out-of-range-end-of-seq. Since that
	isn't a problem, the test was changed to allow for the new output.

	bpf: avoid creating wrong symbols while parsing
	To support the "pseudo-C" asm dialect in BPF, the BPF parser must often
	attempt multiple different templates for a single instruction. In some
	cases this can cause the parser to incorrectly parse part of the
	instruction opcode as an expression, which leads to the creation of a
	new undefined symbol.

	Once the parser recognizes the error, the expression is discarded and it
	tries again with a new instruction template. However, symbols created
	during the process are added to the symbol table and are not removed
	even if the expression is discarded.

	This is a problem for BPF: generally the assembled object will be loaded
	directly to the Linux kernel, without being linked. These erroneous
	parser-created symbols are rejected by the kernel BPF loader, and the
	entire object is refused.

	This patch remedies the issue by tentatively creating symbols while
	parsing instruction operands, and storing them in a temporary list
	rather than immediately inserting them into the symbol table. Later,
	after the parser is sure that it has correctly parsed the instruction,
	those symbols are committed to the real symbol table.

	This approach is modeled directly after Jan Beulich's patch for RISC-V:

	  commit 7a29ee290307087e1749ce610207e93a15d0b78d
	  RISC-V: adjust logic to avoid register name symbols

	gdb: remove regcache's address space
	While looking at the regcache code, I noticed that the address space
	(passed to regcache when constructing it, and available through
	regcache::aspace) wasn't relevant for the regcache itself.  Callers of
	regcache::aspace use that method because it appears to be a convenient
	way of getting the address space for a thread, if you already have the
	regcache.  But there is always another way to get the address space, as
	the callers pretty much always know which thread they are dealing with.
	The regcache code itself doesn't use the address space.

	This patch removes anything related to address_space from the regcache
	code, and updates callers to get it from the thread in context.  This
	removes a bit of unnecessary complexity from the regcache code.

	The current get_thread_arch_regcache function gets an address_space for
	the given thread using the target_thread_address_space function (which
	calls the target_ops::thread_address_space method).  This suggest that
	there might have been the intention of supporting per-thread address
	spaces.  But digging through the history, I did not find any such case.
	Maybe this method was just added because we needed a way to get an
	address space from a ptid (because constructing a regcache required an
	address space), and this seemed like the right way to do it, I don't
	know.

	The only implementations of thread_address_space and
	process_stratum_target::thread_address_space and
	linux_nat_target::thread_address_space, which essentially just return
	the inferior's address space.  And thread_address_space is only used in
	the current get_thread_arch_regcache, which gets removed.  So, I think
	that the thread_address_space target method can be removed, and we can
	assume that it's fine to use the inferior's address space everywhere.
	Callers of regcache::aspace are updated to get the address space from
	the relevant inferior, either using some context they already know
	about, or in last resort using the current global context.

	So, to summarize:

	 - remove everything in regcache related to address spaces
	 - in particular, remove get_thread_arch_regcache, and rename
	   get_thread_arch_aspace_regcache to get_thread_arch_regcache
	 - remove target_ops::thread_address_space, and
	   target_thread_address_space
	 - adjust all users of regcache::aspace to get the address space another
	   way

	Fix gdb.threads/threads-after-exec.exp race
	Simon noticed that gdb.threads/threads-after-exec.exp was racy.  You
	can consistenly reproduce it (at git hash

	  $ taskset -c 0 make check TESTS="gdb.threads/threads-after-exec.exp"

	gdb.log shows:

	The FAILs happen because the .exp file expects that after the exec,
	the only thread has GDB thread number 1, but it has instead 3.

	This is yet another case of zombie leader detection making things a
	bit fuzzy.

	In the passing case, we have:

	 continue

	 [Thread 0x7ffff7bff640 (LWP 600205) exited]
	 process 600202 is executing new program: .../threads-after-exec/threads-after-exec

	The testcase only has two threads, yet GDB presented the exec for
	thread 3.  This is GDB deleting the leader (the backend detected it
	was zombie, due to the exec), and then adding the leader back when it
	saw the exec event.

	I've recorded some thoughts about this in PR gdb/31069.

	For now, this commit just makes the testcase cope with the non-one
	thread number, as the number is not important for what this test is
	exercising.

	[gdb/tui] Factor out tui_noscroll_window et al
	I noticed that tui_locator_window has an empty do_scroll_vertical and

	have:
	...
	  bool can_scroll () const override
	  {
	    return false;
	  }
	...

	I suspect that it probably doesn't matter, but regardless it's good to have
	the same implementations of basic properties in all windows.

	Ensure this by adding a class tui_noscroll_window, that has:
	- an empty do_scroll_vertical and do_scroll_horizontal, and
	- a can_scroll returning false
	which both tui_locator_window and tui_cmd_window inherit.

	Make all methods final to ensure no accidental overrides are left in the
	inheriting classes.

	Likewise add new classes representing basic window properties:
	- tui_nofocus_window,
	- tui_oneline_window,
	- tui_nobox_window,
	- tui_norefresh_window, and
	- tui_always_visible_window.

	The changes are only a refactoring, apart from adding the "final", which does
	limit the range of behaviours for subclasses.

	gdb: implement missing debug handler hook for Python
	This commit builds on the previous commit, and implements the
	extension_language_ops::handle_missing_debuginfo function for Python.
	This hook will give user supplied Python code a chance to help find
	missing debug information.

	The implementation of the new hook is pretty minimal within GDB's C++
	code; most of the work is out-sourced to a Python implementation which
	is modelled heavily on how GDB's Python frame unwinders are
	implemented.

	The following new commands are added as commands implemented in
	Python, this is similar to how the Python unwinder commands are
	implemented:

	  info missing-debug-handlers
	  enable missing-debug-handler LOCUS HANDLER
	  disable missing-debug-handler LOCUS HANDLER

	To make use of this extension hook a user will create missing debug
	information handler objects, and registers these handlers with GDB.
	When GDB encounters an objfile that is missing debug information, each
	handler is called in turn until one is able to help.  Here is a
	minimal handler that does nothing useful:

	  import gdb
	  import gdb.missing_debug

	  class MyFirstHandler(gdb.missing_debug.MissingDebugHandler):
	      def __init__(self):
	          super().__init__("my_first_handler")

	      def __call__(self, objfile):
	          # This handler does nothing useful.
	          return None

	  gdb.missing_debug.register_handler(None, MyFirstHandler())

	Returning None from the __call__ method tells GDB that this handler
	was unable to find the missing debug information, and GDB should ask
	any other registered handlers.

	By extending the __call__ method it is possible for the Python
	extension to locate the debug information for objfile and return a
	value that tells GDB how to use the information that has been located.

	Possible return values from a handler:

	  - None: This means the handler couldn't help.  GDB will call other
	          registered handlers to see if they can help instead.

	  - False: The handler has done all it can, but the debug information
	           for the objfile still couldn't be found.  GDB will not call
		   any other handlers, and will continue without the debug
		   information for objfile.

	  - True: The handler has installed the debug information into a
	          location where GDB would normally expect to find it.  GDB
		  should look again for the debug information.

	  - A string: The handler can return a filename, which is the file
	              containing the missing debug information.  GDB will load
		      this file.

	When a handler returns True, GDB will look again for the debug
	information, but only using the standard built-in build-id and
	.gnu_debuglink based lookup strategies.  It is not possible for an
	extension to trigger another debuginfod lookup; the assumption is that
	the debuginfod server is remote, and out of the control of extensions
	running within GDB.

	Handlers can be registered globally, or per program space.  GDB checks
	the handlers for the current program space first, and then all of the
	global handles.  The first handler that returns a value that is not
	None, has "handled" the objfile, at which point GDB continues.

	gdb: add an extension language hook for missing debug info
	This commit adds a new extension_language_ops hook which allows an
	extension to handle the case where GDB can't find a separate debug
	information file for a particular objfile.

	This commit doesn't actually implement the hook for any of GDB's
	extension languages, the next commit will do that.  This commit just
	adds support for the hook to extension-priv.h and extension.[ch], and
	then reworks symfile-debug.c to call the hook.

	Right now the hook will always return its default value, which means
	GDB should do nothing different.  As such, there should be no user
	visible changes after this commit.

	I'll give a brief description of what the hook does here so that we
	can understand the changes in symfile-debug.c.  The next commit adds a
	Python implementation for this new hook, and gives a fuller
	description of the new functionality.

	Currently, when looking for separate debug information GDB tries three
	things, in this order:

	  1. Use the build-id to find the required debug information,

	  2. Check for .gnu_debuglink section and use that to look up the
	  required debug information,

	  3. Check with debuginfod to see if it can supply the required
	  information.

	The new extension_language_ops::handle_missing_debuginfo hook is
	called if all three steps fail to find any debug information.  The
	hook has three possible return values:

	  a. Nothing, no debug information is found, GDB continues without the
	  debug information for this objfile.  This matches the current
	  behaviour of GDB, and is the default if nothing is implementing this
	  new hook,

	  b. Install debug information into a location that step #1 or #2
	  above would normally check, and then request that GDB repeats steps
	  #1 and #2 in the hope that GDB will now find the debug information.
	  If the debug information is still not found then GDB carries on
	  without the debug information.  If the debug information is found
	  the GDB loads it and carries on,

	  c. Return a filename for a file containing the required debug
	  information.  GDB loads the contents of this file and carries on.

	The changes in this commit mostly involve placing the core of
	objfile::find_and_add_separate_symbol_file into a loop which allows
	for steps #1 and #2 to be repeated.

	We take care to ensure that debuginfod is only queried once, the first
	time through.  The assumption is that no extension is going to be able
	to control the replies from debuginfod, so there's no point making a
	second request -- and as these requests go over the network, they
	could potentially be slow.

	The warnings that find_and_add_separate_symbol_file collects are
	displayed only once assuming that no debug information is found.  If
	debug information is found, even after the extension has operated,
	then the warnings are not shown; remember, these are warnings from GDB
	about failure to find any suitable debug information, so it makes
	sense to hide these if debug information is found.

	gdb: refactor objfile::find_and_add_separate_symbol_file
	This is purely a refactoring commit.

	This commit splits objfile::find_and_add_separate_symbol_file into
	some separate helper functions.  My hope is that the steps for looking
	up separate debug information are now clearer.

	In a later commit I'm going to extend
	objfile::find_and_add_separate_symbol_file, with some additional
	logic, so starting with a simpler function will make the following
	changes easier.

	When reading objfile::find_and_add_separate_symbol_file after this
	commit, you might be tempted to think that removing the `has_dwarf`
	local variable would be a good additional cleanup.  After the next
	commit though it makes more sense to retain this local, so I've left
	this in place for now.

	There should be no user visible changes after this commit.

	gdb: merge debug symbol file lookup code from coffread & elfread paths
	This commit merges the code that looks for and loads the separate
	debug symbol files from coffread.c and elfread.c.  The factored out
	code is moved into a new objfile::find_and_add_separate_symbol_file()
	method.

	For the elfread.c path there should be no user visible changes after
	this commit.

	For the coffread.c path GDB will now attempt to perform a debuginfod
	lookup for the missing debug information, assuming that GDB can find a
	build-id in the COFF file.

	I don't know if COFF files can include a build-id, but I the existing
	coffread.c code already includes a call to
	find_separate_debug_file_by_build-id, so I know that it is at least OK
	for GDB to ask a COFF file for a build-id.  If the COFF file doesn't
	include a build-id then the debuginfod lookup code will not trigger
	and the new code is harmless.

	If the COFF file does include a build-id, then we're going to end up
	asking debuginfod for the debug file.  As build-ids should be unique,
	this should be harmless, even if debuginfod doesn't contain any
	suitable debug data, it just costs us one debuginfod lookup, so I'm
	not too worried about this for now.

	As with the previous commit, I've done some minimal testing using the
	mingw toolchain on a Linux machine, GDB seems to still access the
	split debug information just fine.

	gdb/coffread: bring separate debug file logic into line with elfread.c
	In this commit:

	  commit 8a92335bfca80cc9b4cd217505ea0dcbfdefbf07
	  Date:   Fri Feb 1 19:39:04 2013 +0000

	the logic for when we try to load a separate debug file in elfread.c
	was extended.  The new code checks that the objfile doesn't already
	have a separate debug objfile linked to it, and that the objfile isn't
	itself a separate debug objfile for some other objfile.

	The coffread code wasn't extended at the same time.

	I don't know if it's possible for the coffread code to get into the
	same state where these checks are needed, but I don't see why having
	these checks would be a problem.  In a later commit I plan to merge
	this part of the elfread and coffread code, so bringing these two
	pieces of code into line first makes that job easier.

	I've tested this with a simple test binary compiled with the mingw
	toolchain on a Linux host.  After compiling the binary and splitting
	out the debug info GDB still finds and loads the separate debug info.

	The gdb.ada/inline-section-gc.exp test may pass or fail depending on the
	version of gnat.  Per the discussion on IRC, the ada inlining appears to
	have some target dependencies.  In this test there are two functions,
	callee and caller. Function calee is inlined into caller.  The test sets
	a breakpoint in function callee.  The reported location where the
	breakpoint is set may be at the requested location in callee or the
	location in caller after callee has been inlined.  The test needs to
	accept either location as correct provided the breakpoint address is not
	zero.

	This patch checks to see if the reported breakpoint is in function callee
	or function caller and fails if the breakpoint address is 0x0.  The line
	number where the breakpoint is set will match the requested line if the
	breakpoint location is reported is callee.adb.  If the breakpoint is
	reported in caller.adb, the line number in caller is the breakpoint
	location in callee where it is inlined into caller.

	This patch fixes the single regression failure for the test on PowerPC.
	It does not introduce any failures on X86-64.

	Cancel execution command on thread exit, when stepping, nexting, etc.
	If your target has no support for TARGET_WAITKIND_NO_RESUMED events
	(and no way to support them, such as the yet-unsubmitted AMDGPU
	target), and you step over thread exit with scheduler-locking on, this
	is what you get:

	 (gdb) n
	 [Thread ... exited]
	 *hang*

	Getting back the prompt by typing Ctrl-C may not even work, since no
	inferior thread is running to receive the SIGINT.  Even if it works,
	it seems unnecessarily harsh.  If you started an execution command for
	which there's a clear thread of interest (step, next, until, etc.),
	and that thread disappears, then I think it's more user friendly if
	GDB just detects the situation and aborts the command, giving back the
	prompt.

	That is what this commit implements.  It does this by explicitly
	requesting the target to report thread exit events whenever the main
	resumed thread has a thread_fsm.  Note that unlike stepping over a
	breakpoint, we don't need to enable clone events in this case.

	With this patch, we get:

	 (gdb) n
	 [Thread 0x7ffff7d89700 (LWP 3961883) exited]
	 Command aborted, thread exited.

	Report thread exit event for leader if reporting thread exit events
	If GDB sets the GDB_THREAD_OPTION_EXIT option on a thread, then if the
	thread disappears from the thread list, GDB expects to shortly see a
	thread exit event for it.  See e.g., here, in
	remote_target::update_thread_list():

	    /* Do not remove the thread if we've requested to be
	       notified of its exit.  For example, the thread may be
	       displaced stepping, infrun will need to handle the
	       exit event, and displaced stepping info is recorded
	       in the thread object.  If we deleted the thread now,
	       we'd lose that info.  */
	    if ((tp->thread_options () & GDB_THREAD_OPTION_EXIT) != 0)
	      continue;

	There's one scenario that is deleting a thread from the
	remote/gdbserver thread list without ever reporting a corresponding
	thread exit event though -- check_zombie_leaders.  This can lead to
	GDB getting confused.  For example, with a following patch that
	enables GDB_THREAD_OPTION_EXIT whenever schedlock is enabled, we'd see
	this regression:

	 $ make check RUNTESTFLAGS="--target_board=native-extended-gdbserver" TESTS="gdb.threads/no-unwaited-for-left.exp"

	Even though that thread is not on the remote-reported thread list, it
	is still on the GDB thread list, due to the special case in remote.c
	mentioned above.

	This commit addresses the issue by fixing GDBserver to report a thread
	exit event for the zombie leader too, i.e., making GDBserver respect
	the "if thread has GDB_THREAD_OPTION_EXIT set, report a thread exit"
	invariant.  To do that, it takes a bit more code than one would
	imagine off hand, due to the fact that we currently always report LWP
	exit pending events as TARGET_WAITKIND_EXITED, and then decide whether
	to convert it to TARGET_WAITKIND_THREAD_EXITED just before reporting
	the event to GDBserver core.  For the zombie leader scenario
	described, we need to record early on that we want to report a
	THREAD_EXITED event, and then make sure that decision isn't lost along
	the way to reporting the event to GDBserver core.

	Don't resume new threads if scheduler-locking is in effect
	If scheduler-locking is in effect, e.g., with "set scheduler-locking
	on", and you step over a function that spawns a new thread, the new
	thread is allowed to run free, at least until some event is hit, at
	which point, whether the new thread is re-resumed depends on a number
	of seemingly random factors.  E.g., if the target is all-stop, and the
	parent thread hits a breakpoint, and GDB decides the breakpoint isn't
	interesting to report to the user, then the parent thread is resumed,
	but the new thread is left stopped.

	I think that letting the new threads run with scheduler-locking

	gdbserver: Queue no-resumed event after thread exit
	Normally, if the last resumed thread on the target exits, the server
	sends a no-resumed event to GDB.  If however, GDB enables the
	GDB_THREAD_OPTION_EXIT option on a thread, and, that thread exits, the
	server sends a thread exit event for that thread instead.

	In all-stop RSP mode, since events can only be forwarded to GDB one at
	a time, and the whole target stops whenever an event is reported, GDB
	resumes the target again after getting a THREAD_EXITED event, and then
	the server finally reports back a no-resumed event if/when
	appropriate.

	For non-stop RSP though, events are asynchronous, and if the server
	sends a thread-exit event for the last resumed thread, the no-resumed
	event is never sent.  This patch makes sure that in non-stop mode, the
	server queues a no-resumed event after the thread-exit event if it was
	the last resumed thread that exited.

	Without this, we'd see failures in step-over-thread-exit testcases
	added later in the series, like so:

	stop_all_threads stops listening to events from a target as soon as it
	sees a TARGET_WAITKIND_NO_RESUMED, ignoring that
	TARGET_WAITKIND_NO_RESUMED may be delayed.  handle_no_resumed knows
	how to handle delayed no-resumed events, but stop_all_threads was
	never taught to.

	In more detail, here's what happens with that testcase:

	#1 - Multiple threads report breakpoint hits to gdb.

	#2 - gdb picks one events, and it's for thread 1.  All other stops are
	     left pending.  thread 1 needs to move past a breakpoint, so gdb
	     stops all threads to start an inline step over for thread 1.
	     While stopping threads, some of the threads that were still
	     running report events that are also left pending.

	#2 - gdb steps thread 1

	#3 - Thread 1 exits while stepping (it steps over an exit syscall),
	     gdbserver reports thread exit for thread 1

	#4 - Thread 1 was the last resumed thread, so gdbserver also reports
	     no-resumed:

	    [remote]   Notification received: Stop:w0;p3445d0.3445d3
	    [remote] Sending packet: $vStopped#55
	    [remote] Packet received: N
	    [remote] Sending packet: $vStopped#55
	    [remote] Packet received: OK

	#5 - gdb processes the thread exit for thread 1, finishes the step
	     over and restarts threads.

	#6 - gdb picks the next event to process out of one of the resumed
	     threads with pending events:

	    [infrun] random_resumed_with_pending_wait_status: Found 32 events, selecting #11

	#7 - This is again a breakpoint hit and the breakpoint needs to be
	     stepped over too, so gdb starts a step-over dance again.

	#8 - We reach stop_all_threads, which finds that some threads need to
	     be stopped.

	#9 - wait_one finally consumes the no-resumed event queue by #4.
	     Seeing this, wait_one disable target async, to stop listening for
	     events out of the remote target.

	#10 - We still haven't seen all the stops expected, so
	      stop_all_threads tries another iteration.

	#11 - Because the remote target is no longer async, and there are no
	      other targets, wait_one return no-resumed immediately without
	      polling the remote target.

	#12 - We still haven't seen all the stops expected, so
	      stop_all_threads tries another iteration.  goto #11, looping
	      forever.

	Fix this by explicitly enabling/re-enabling target async on targets
	that can async, before waiting for stops.

	gdb: clear step over information on thread exit (PR gdb/27338)
	GDB doesn't handle correctly the case where a thread steps over a
	breakpoint (using either in-line or displaced stepping), and the
	executed instruction causes the thread to exit.

	Using the test program included later in the series, this is what it
	looks like with displaced-stepping, on x86-64 Linux, where we have two
	displaced-step buffers:

	  ... hangs ...

	The first two times we do "continue", we displaced-step the syscall
	instruction that causes the thread to exit.  When the thread exits,
	the main thread, waiting on pthread_join, is unblocked.  It spawns a
	new thread, which hits the breakpoint on the syscall again.  However,
	infrun was never notified that the displaced-stepping threads are done
	using the displaced-step buffer, so now both buffers are marked as
	used.  So when we do the third continue, there are no buffers
	available to displaced-step the syscall, so the thread waits forever
	for its turn.

	  ... hangs ...

	The "continue" causes an in-line step to occur, meaning the main
	thread is stopped while we step the syscall.  The stepped thread exits
	when executing the syscall, the linux-nat target notices there are no
	more resumed threads to be waited for, so returns
	TARGET_WAITKIND_NO_RESUMED, which causes the prompt to return.  But
	infrun never clears the in-line step over info.  So if we try
	continuing the main thread, GDB doesn't resume it, because it thinks
	there's an in-line step in progress that we need to wait for to
	finish, and we are stuck there.

	To fix this, infrun needs to be informed when a thread doing a
	displaced or in-line step over exits.  We can do that with the new
	target_set_thread_options mechanism which is optimal for only enabling
	exit events of the thread that needs it; or, if that is not supported,
	by using target_thread_events, which enables thread exit events for
	all threads.  This is done by this commit.

	This patch then modifies handle_inferior_event in infrun.c to clean up
	any step-over the exiting thread might have been doing at the time of
	the exit.  The cases to consider are:

	 - the exiting thread was doing an in-line step-over with an all-stop
	   target
	 - the exiting thread was doing an in-line step-over with a non-stop
	   target
	 - the exiting thread was doing a displaced step-over with a non-stop
	   target

	The displaced-stepping buffer implementation in displaced-stepping.c
	is modified to account for the fact that it's possible that we
	"finish" a displaced step after a thread exit event.  The buffer that
	the exiting thread was using is marked as available again and the
	original instructions under the scratch pad are restored.  However, it
	skips applying the fixup, which wouldn't make sense since the thread
	does not exist anymore.

	Another case that needs handling is if a displaced-stepping thread
	exits, and the event is reported while we are in stop_all_threads.  We
	should call displaced_step_finish in the handle_one function, in that
	case.  It was already called in other code paths, just not the "thread
	exited" path.

	This commit doesn't make infrun ask the target to report the
	TARGET_WAITKIND_THREAD_EXITED events yet, that'll be done later in the
	series.

	Note that "stop_print_frame = false;" line is moved to normal_stop,
	because TARGET_WAITKIND_THREAD_EXITED can also end up with the event
	transmorphed into TARGET_WAITKIND_NO_RESUMED.  Moving it to
	normal_stop keeps it centralized.

	Introduce GDB_THREAD_OPTION_EXIT thread option, fix step-over-thread-exit
	When stepping over a breakpoint with displaced stepping, GDB needs to
	be informed if the stepped thread exits, otherwise the displaced
	stepping buffer that was allocated to that thread leaks, and this can
	result in deadlock, with other threads waiting for their turn to
	displaced step, but their turn never comes.

	Similarly, when stepping over a breakpoint in line, GDB also needs to
	be informed if the stepped thread exits, so that is can clear the step
	over state and re-resume threads.

	This commit makes it possible for GDB to ask the target to report
	thread exit events for a given thread, using the new "thread options"
	mechanism introduced by a previous patch.

	This only adds the core bits.  Following patches in the series will
	teach the Linux backends (native & gdbserver) to handle the
	GDB_THREAD_OPTION_EXIT option, and then a later patch will make use of
	these thread exit events to clean up displaced stepping and inline
	stepping state properly.

	gdbserver/linux-low.cc: Ignore event_ptid if TARGET_WAITKIND_IGNORE
	gdbserver's linux_process_target::wait loops if:

	 - called in sync mode, and,
	 - wait_1 returns TARGET_WAITKIND_IGNORE, _and_,
	 - wait_1 also returns null_ptid.

	The null_ptid check fails however when this path is taken:

	   ptid_t
	   linux_process_target::filter_exit_event (lwp_info *event_child,
						    target_waitstatus *ourstatus)
	   {

		 delete_lwp (event_child);
	       }
	     return ptid;
	   }

	This makes linux_process_target::wait return TARGET_WAITKIND_IGNORE in
	sync mode, which is unexpected by the core and fails an assertion.

	This commit fixes it by just making linux_process_target::wait loop if
	it got a TARGET_WAITKIND_IGNORE, irrespective of event_ptid.

	all-stop/synchronous RSP support thread-exit events

	Thread options & clone events (core + remote)
	A previous patch taught GDB about a new TARGET_WAITKIND_THREAD_CLONED
	event kind, and made the Linux target report clone events.

	A following patch will teach Linux GDBserver to do the same thing.

	However, for remote debugging, it wouldn't be ideal for GDBserver to
	report every clone event to GDB, when GDB only cares about such events
	in some specific situations.  Reporting clone events all the time
	would be potentially chatty.  We don't enable thread create/exit
	events all the time for the same reason.  Instead we have the
	QThreadEvents packet.  QThreadEvents is target-wide, though.

	This patch makes GDB instead explicitly request that the target
	reports clone events or not, on a per-thread basis.

	In order to be able to do that with GDBserver, we need a new remote
	protocol feature.  Since a following patch will want to enable thread
	exit events on per-thread basis too, the packet introduced here is
	more generic than just for clone events.  It lets you enable/disable a
	set of options at once, modelled on Linux ptrace's PTRACE_SETOPTIONS.

	IOW, this commit introduces a new QThreadOptions packet, that lets you
	specify a set of per-thread event options you want to enable.  The
	packet accepts a list of options/thread-id pairs, similarly to vCont,
	processed left to right, with the options field being a number
	interpreted as a bit mask of options.  The only option defined in this
	commit is GDB_THREAD_OPTION_CLONE (0x1), which ask the remote target
	to report clone events.  Another patch later in the series will
	introduce another option.

	For example, this packet sets option "1" (clone events) on thread
	p1000.2345:

	  QThreadOptions;1:p1000.2345

	and this clears options for all threads of process 1000, and then sets
	option "1" (clone events) on thread p1000.2345:

	  QThreadOptions;0:p1000.-1;1:p1000.2345

	This clears options of all threads of all processes:

	  QThreadOptions;0

	The target reports the set of supported options by including
	"QThreadOptions=<supported options>" in its qSupported response.

	infrun is then tweaked to enable GDB_THREAD_OPTION_CLONE when stepping
	over a breakpoint.

	Unlike PTRACE_SETOPTIONS, fork/vfork/clone children do NOT inherit
	their parent's thread options.  This is so that GDB can send e.g.,
	"QThreadOptions;0;1:TID" without worrying about threads it doesn't
	know about yet.

	Documentation for this new remote protocol feature is included in a
	documentation patch later in the series.

	Support clone events in the remote protocol
	The previous patch taught GDB about a new
	TARGET_WAITKIND_THREAD_CLONED event kind, and made the Linux target
	report clone events.

	A following patch will teach Linux GDBserver to do the same thing.

	But before we get there, we need to teach the remote protocol about
	TARGET_WAITKIND_THREAD_CLONED.  That's what this patch does.  Clone is
	very similar to vfork and fork, and the new stop reply is likewise
	handled similarly.  The stub reports "T05clone:...".

	GDBserver core is taught to handle TARGET_WAITKIND_THREAD_CLONED and
	forward it to GDB in this patch, but no backend actually emits it yet.
	That will be done in a following patch.

	Documentation for this new remote protocol feature is included in a

	Step over clone syscall w/ breakpoint, TARGET_WAITKIND_THREAD_CLONED
	(A good chunk of the problem statement in the commit log below is
	Andrew's, adjusted for a different solution, and for covering
	displaced stepping too.  The testcase is mostly Andrew's too.)

	This commit addresses bugs gdb/19675 and gdb/27830, which are about
	stepping over a breakpoint set at a clone syscall instruction, one is
	about displaced stepping, and the other about in-line stepping.

	Currently, when a new thread is created through a clone syscall, GDB
	sets the new thread running.  With 'continue' this makes sense
	(assuming no schedlock):

	 - all-stop mode, user issues 'continue', all threads are set running,
	   a newly created thread should also be set running.

	 - non-stop mode, user issues 'continue', other pre-existing threads
	   are not affected, but as the new thread is (sort-of) a child of the
	   thread the user asked to run, it makes sense that the new threads
	   should be created in the running state.

	Similarly, if we are stopped at the clone syscall, and there's no
	software breakpoint at this address, then the current behaviour is
	fine:

	 - all-stop mode, user issues 'stepi', stepping will be done in place
	   (as there's no breakpoint to step over).  While stepping the thread
	   of interest all the other threads will be allowed to continue.  A
	   newly created thread will be set running, and then stopped once the
	   thread of interest has completed its step.

	 - non-stop mode, user issues 'stepi', stepping will be done in place
	   (as there's no breakpoint to step over).  Other threads might be
	   running or stopped, but as with the continue case above, the new
	   thread will be created running.  The only possible issue here is
	   that the new thread will be left running after the initial thread
	   has completed its stepi.  The user would need to manually select
	   the thread and interrupt it, this might not be what the user
	   expects.  However, this is not something this commit tries to
	   change.

	The problem then is what happens when we try to step over a clone
	syscall if there is a breakpoint at the syscall address.

	- For both all-stop and non-stop modes, with in-line stepping:

	   + user issues 'stepi',
	   + [non-stop mode only] GDB stops all threads.  In all-stop mode all
	     threads are already stopped.
	   + GDB removes s/w breakpoint at syscall address,
	   + GDB single steps just the thread of interest, all other threads
	     are left stopped,
	   + New thread is created running,
	   + Initial thread completes its step,
	   + [non-stop mode only] GDB resumes all threads that it previously
	     stopped.

	There are two problems in the in-line stepping scenario above:

	  1. The new thread might pass through the same code that the initial
	     thread is in (i.e. the clone syscall code), in which case it will
	     fail to hit the breakpoint in clone as this was removed so the
	     first thread can single step,

	  2. The new thread might trigger some other stop event before the
	     initial thread reports its step completion.  If this happens we
	     end up triggering an assertion as GDB assumes that only the
	     thread being stepped should stop.  The assert looks like this:

	     infrun.c:5899: internal-error: int finish_step_over(execution_control_state*): Assertion `ecs->event_thread->control.trap_expected' failed.

	- For both all-stop and non-stop modes, with displaced stepping:

	   + user issues 'stepi',
	   + GDB starts the displaced step, moves thread's PC to the
	     out-of-line scratch pad, maybe adjusts registers,
	   + GDB single steps the thread of interest, [non-stop mode only] all
	     other threads are left as they were, either running or stopped.
	     In all-stop, all other threads are left stopped.
	   + New thread is created running,
	   + Initial thread completes its step, GDB re-adjusts its PC,
	     restores/releases scratchpad,
	   + [non-stop mode only] GDB resumes the thread, now past its
	     breakpoint.
	   + [all-stop mode only] GDB resumes all threads.

	There is one problem with the displaced stepping scenario above:

	  3. When the parent thread completed its step, GDB adjusted its PC,
	     but did not adjust the child's PC, thus that new child thread
	     will continue execution in the scratch pad, invoking undefined
	     behavior.  If you're lucky, you see a crash.  If unlucky, the
	     inferior gets silently corrupted.

	What is needed is for GDB to have more control over whether the new
	thread is created running or not.  Issue #1 above requires that the
	new thread not be allowed to run until the breakpoint has been
	reinserted.  The only way to guarantee this is if the new thread is
	held in a stopped state until the single step has completed.  Issue #3
	above requires that GDB is informed of when a thread clones itself,
	and of what is the child's ptid, so that GDB can fixup both the parent
	and the child.

	When looking for solutions to this problem I considered how GDB
	handles fork/vfork as these have some of the same issues.  The main
	difference between fork/vfork and clone is that the clone events are
	not reported back to core GDB.  Instead, the clone event is handled
	automatically in the target code and the child thread is immediately
	set running.

	Note we have support for requesting thread creation events out of the
	target (TARGET_WAITKIND_THREAD_CREATED).  However, those are reported
	for the new/child thread.  That would be sufficient to address in-line
	stepping (issue #1), but not for displaced-stepping (issue #3).  To
	handle displaced-stepping, we need an event that is reported to the
	_parent_ of the clone, as the information about the displaced step is
	associated with the clone parent.  TARGET_WAITKIND_THREAD_CREATED
	includes no indication of which thread is the parent that spawned the
	new child.  In fact, for some targets, like e.g., Windows, it would be
	impossible to know which thread that was, as thread creation there
	doesn't work by "cloning".

	The solution implemented here is to model clone on fork/vfork, and
	introduce a new TARGET_WAITKIND_THREAD_CLONED event.  This event is
	similar to TARGET_WAITKIND_FORKED and TARGET_WAITKIND_VFORKED, except
	that we end up with a new thread in the same process, instead of a new
	thread of a new process.  Like FORKED and VFORKED, THREAD_CLONED
	waitstatuses have a child_ptid property, and the child is held stopped
	until GDB explicitly resumes it.  This addresses the in-line stepping
	case (issues #1 and #2).

	The infrun code that handles displaced stepping fixup for the child
	after a fork/vfork event is thus reused for THREAD_CLONE, with some
	minimal conditions added, addressing the displaced stepping case
	(issue #3).

	The native Linux backend is adjusted to unconditionally report
	TARGET_WAITKIND_THREAD_CLONED events to the core.

	Following the follow_fork model in core GDB, we introduce a
	target_follow_clone target method, which is responsible for making the
	new clone child visible to the rest of GDB.

	Subsequent patches will add clone events support to the remote
	protocol and gdbserver.

	displaced_step_in_progress_thread becomes unused with this patch, but
	a new use will reappear later in the series.  To avoid deleting it and
	readding it back, this patch marks it with attribute unused, and the
	latter patch removes the attribute again.  We need to do this because
	the function is static, and with no callers, the compiler would warn,
	(error with -Werror), breaking the build.

	This adds a new gdb.threads/stepi-over-clone.exp testcase, which
	exercises stepping over a clone syscall, with displaced stepping vs
	inline stepping, and all-stop vs non-stop.  We already test stepping
	over clone syscalls with gdb.base/step-over-syscall.exp, but this test
	uses pthreads, while the other test uses raw clone, and this one is
	more thorough.  The testcase passes on native GNU/Linux, but fails
	against GDBserver.  GDBserver will be fixed by a later patch in the
	series.

	gdb/linux: Delete all other LWPs immediately on ptrace exec event
	I noticed that on an Ubuntu 20.04 system, after a following patch
	("Step over clone syscall w/ breakpoint,
	TARGET_WAITKIND_THREAD_CLONED"), the gdb.threads/step-over-exec.exp
	was passing cleanly, but still, we'd end up with four new unexpected
	GDB core dumps:

			 === gdb Summary ===

	 # of unexpected core files      4
	 # of expected passes            48

	That said patch is making the pre-existing
	gdb.threads/step-over-exec.exp testcase (almost silently) expose a
	latent problem in gdb/linux-nat.c, resulting in a GDB crash when:

	 #1 - a non-leader thread execs
	 #2 - the post-exec program stops somewhere
	 #3 - you kill the inferior

	Instead of #3 directly, the testcase just returns, which ends up in
	gdb_exit, tearing down GDB, which kills the inferior, and is thus
	equivalent to #3 above.

	Vis (after said patch is applied):

	The root of the problem is that when a non-leader LWP execs, it just
	changes its tid to the tgid, replacing the pre-exec leader thread,
	becoming the new leader.  There's no thread exit event for the execing
	thread.  It's as if the old pre-exec LWP vanishes without trace.  The
	ptrace man page says:

	 "PTRACE_O_TRACEEXEC (since Linux 2.5.46)
		Stop the tracee at the next execve(2).  A waitpid(2) by the
		tracer will return a status value such that

		  status>>8 == (SIGTRAP | (PTRACE_EVENT_EXEC<<8))

		If the execing thread is not a thread group leader, the thread
		ID is reset to thread group leader's ID before this stop.
		Since Linux 3.0, the former thread ID can be retrieved with
		PTRACE_GETEVENTMSG."

	When the core of GDB processes an exec events, it deletes all the
	threads of the inferior.  But, that is too late -- deleting the thread
	does not delete the corresponding LWP, so we end leaving the pre-exec
	non-leader LWP stale in the LWP list.  That's what leads to the crash
	above -- linux_nat_target::kill iterates over all LWPs, and after the
	patch in question, that code will look for the corresponding
	thread_info for each LWP.  For the pre-exec non-leader LWP still
	listed, won't find one.

	This patch fixes it, by deleting the pre-exec non-leader LWP (and
	thread) from the LWP/thread lists as soon as we get an exec event out
	of ptrace.

	GDBserver does not need an equivalent fix, because it is already doing
	this, as side effect of mourning the pre-exec process, in
	gdbserver/linux-low.cc:

	  else if (event == PTRACE_EVENT_EXEC && cs.report_exec_events)
	    {
	...
	      /* Delete the execing process and all its threads.  */
	      mourn (proc);
	      switch_to_thread (nullptr);


	The crash with gdb.threads/step-over-exec.exp is not observable on
	newer systems, which postdate the glibc change to move "libpthread.so"
	internals to "libc.so.6", because right after the exec, GDB traps a
	load event for "libc.so.6", which leads to GDB trying to open
	libthread_db for the post-exec inferior, and, on such systems that
	succeeds.  When we load libthread_db, we call
	linux_stop_and_wait_all_lwps, which, as the name suggests, stops all
	lwps, and then waits to see their stops.  While doing this, GDB
	detects that the pre-exec stale LWP is gone, and deletes it.

	If we use "catch exec" to stop right at the exec before the
	"libc.so.6" load event ever happens, and issue "kill" right there,
	then GDB crashes on newer systems as well.  So instead of tweaking
	gdb.threads/step-over-exec.exp to cover the fix, add a new
	gdb.threads/threads-after-exec.exp testcase that uses "catch exec".
	The test also uses the new "maint info linux-lwps" command if testing
	on Linux native, which also exposes the stale LWP problem with an
	unfixed GDB.

	Also tweak a comment in infrun.c:follow_exec referring to how
	linux-nat.c used to behave, as it would become stale otherwise.

	Add "maint info linux-lwps" command
	This adds a maintenance command that lets you list all the LWPs under
	control of the linux-nat target.

	For example:

	 (gdb) maint info linux-lwps
	 LWP Ptid        Thread ID
	 560948.561047.0 None
	 560948.560948.0 1.1

	This shows that "560948.561047.0" LWP doesn't map to any thread_info
	object, which is bogus.  We'll be using this in a testcase in a
	following patch.

	bfd: use less memory in string merging
	the offset-to-entry mappings are allocated in blocks, which may
	become a bit wasteful in case there are extremely many small
	input files or sections.  This made it so that a large project
	(Qt5WebEngine) didn't build anymore on x86 32bit due to address
	space limits.  It barely fit into address space before the new
	string merging, and then got pushed over the limit by this.

	So instead of leaving the waste reallocate the maps to their final

	The tests are not compatible with ilp32 abi: the GNU property

	not trivial.

	ld: aarch64: Add BTI stub insertion test PR30930
	The test creates a large shared library and covers a number of
	BTI stub insertion cases.

2023-11-09  Szabolcs Nagy  <szabolcs.nagy@arm.com>

	bfd: aarch64: Avoid BTI stub for a PLT that has BTI
	We decide to emit BTI stubs based on the instruction at the target
	location. But PLT code is generated later than the stubs so we always
	read 0 which is not a valid BTI.

	Fix the logic to special case the PLT section: this is code the linker
	generates so we know when it will have BTI.

	This avoids BTI stubs in large executables where the PLTs have them
	already. An alternative is to never emit BTI stubs for PLTs, instead
	use BTI in the PLT if a library gets too big, however that may be
	more tricky given the ordering of PLT sizing and stub insertion.

	Related to bug 30957.

	bfd: aarch64: Fix leaks in case of BTI stub reuse
	BTI stub parameters were recomputed even if those were already set up.
	This is unnecessary work and leaks the symbol name that is allocated
	for the stub.

2023-11-09  Szabolcs Nagy  <szabolcs.nagy@arm.com>

	bfd: aarch64: Fix broken BTI stub PR30930
	Input sections are grouped together that can use the same stub area
	(within reach) and these groups have a stable id.

	Stubs have a name generated from the stub group id and target symbol.
	When a relocation requires a stub with a name that already exists, the
	stub is reused instead of adding a new one.

	For an indirect branch stub another BTI stub may be inserted near the
	target to provide a BTI landing pad.

	The BTI stub can end up with the same stub group id and thus the same
	name as the indirect stub. This happens if the target symbol is within
	reach of the indirect branch stub. Then, due to the name collision,
	only a single stub was emmitted which branched to itself causing an
	infinite loop at runtime.

	A possible solution is to just name the BTI stubs differently, but
	since in the problematic case the indirect and BTI stub are in the
	same stub area, a better solution is to emit a single stub with a
	direct branch. The stub is still needed since the caller cannot reach
	the target directly and we also want a BTI landing pad in the stub in
	case other indirect stubs target the same symbol and thus need a BTI
	stub.

	In short we convert an indirect branch stub into a BTI stub when the
	target is within reach and has no BTI. It is a hassle to change the
	symbol of the stub so a BTI stub may end up with *_veneer instead of
	*_bti_veneer after the conversion, but this should not matter much.
	(Refactoring some of _bfd_aarch64_add_call_stub_entries would be
	useful but too much for this bug fix patch.)

	The same conversion to direct branch could be done even if the target
	did not need a BTI. The stub groups are fixed in the current logic so
	linking can fail if too many stubs are inserted and the section layout
	is changed too much, but this only happens in extreme cases that can
	be reasonably ignored. Because of this the target cannot go out of
	reach during stub insertion so the optimization is valid, but not
	implemented by this patch for the non-BTI case.

	Fixes bug 30930.

	  bfd: aarch64: Optimize BTI stubs PR30076

	Furthermore, in separating system register from instruction
	implementation (with which only the former was of concern in the cited

	that these can be added later when adding THE instructions to the

	x86: rework UWRMSR operand swapping

	x86: do away with is_evex_encoding()
	As we have grown more uses of it, it becomes increasingly more desirable
	to replace it by a simpler check. Have i386-gen do at build time what so
	far was done at runtime: Deal with templates indicating EVEX-encoding by
	other than the EVex attribute, and set that to "dynamic" in such cases.

	This then allows simplifying a number of other conditionals as well.

2023-11-09  Jan Beulich  <jbeulich@suse.com>

	x86: split insn templates' CPU field
	Right now the opcode table has entries with ISA restrictions of the form
	FEAT1|FEAT2, the meaning of which depends on context and requires
	special treatment in tc-i386.c: Sometimes this means "both features
	requires", whereas originally it was intended to solely mean "all of
	these features required". Split the field, with the original one
	regaining its original meaning. The new field now truly means "any of
	these". The combination of both fields is still and &&-type check, i.e.
	(all of these) && (any of these). In the opcode table more involved
	combinations of features then also need expressing this way: "all"
	entities first, follow by "any" entities enclosed in parentheses, e.g.
	x64&(AVX|AVX512F). If the "all" part is empty, parentheses may not be
	added around the "any" part (unless parsing logic was further relaxed).

	Note that this way AVX512VL no longer needs as much special treatment,
	and hence templates previously using AVX512F|AVX512VL are switched to
	just AVX512VL.

	Note further that this requires FMA handling as resulting from
	da0784f961d8 ("x86: fold FMA VEX and EVEX templates") to be slightly
	re-done: FMA now becomes more similar to AVX and AVX2.

	x86: Cpu64 handling improvements
	First of all we want to also accumulate its reverse dependencies, such
	that we can use them in cpu_flags_match(). This is in particular in
	preparation of APX additions, such that e.g. BMI VEX-encoding templates
	can become combined VEX/EVEX ones.

	Once we have the reverse dependencies, we can further leverage them to
	omit explicit "&x64" from any insn templates dealing with 64-bit-mode-
	only ISA extensions. Besides helping readability for several insn
	templates we already have, this will also help with what is going to be
	added for APX (as all of the new templates would otherwise need to have
	"&x64").

	Note that rather than leaving a meaningless CPU_64_FLAGS (which is
	unused anyway), its emitting is now also suppressed.

	x86: Intel Core processors do not support CMPXCHG16B

	rs6000, Fix test gdb.base/store.exp
	The test currently fails for IEEE 128-bit floating point types.  PowerPC
	supports the IBM double 128-bit floating point format and IEEE 128-bit
	format.  The IBM double 128-bit floating point format uses two 64-bit
	floating point registers to store the 128-bit value.  The IEEE 128-bit
	floating point format stores the value in a single 128-bit vector-scalar
	register (vsr).

	The various floating point values, 32-bit float, 64-bit double, IBM double
	128-bit float and IEEE 128-bit floating point numbers are all mapped to the
	DWARF fpr numbers.  The issue is the IEEE 128-bit floating point values are
	actually stored in a vsr not the fprs.  This patch changes the register
	mapping for the vsrs from the fpr to the vsr registers so the value is
	properly accessed by GDB.  The functions rs6000_linux_register_to_value,
	rs6000_linux_value_to_register, rs6000_linux_value_from_register check if
	the value is an IEEE 128-bit floating point value and adjust the register
	number as needed.  The test in function rs6000_convert_register_p is fixed
	so it is only true for floating point values.

	This patch fixes three regression tests in gdb.base/store.exp.

	The patch has been tested on Power 8 LE/BE, Power 9 LE/BE and Power 10 LE
	with no regressions.

2023-11-08  Carl Love  <cel@us.ibm.com>

	rs6000, Fix Linux DWARF register mapping
	Overview of issues fixed by the patch.

	The primary issue this patch fixes is the DWARF register mapping for
	Linux.  The changes in ppc-linux-tdep.c fix the DWARF register mapping
	issues.  The register mapping issue is responsible for two of the
	five regression bugs seen in gdb.base/store.exp.

	Once the register mapping was fixed, an underlying issue with the unwinding
	of the signal trampoline in common-code in ifrun.c was found.  This
	underlying bug is best described by Ulrich in the following description.

	  The unwinder bug shows up on platforms where the kernel uses a trampoline
	  to dispatch "calls to" the signal handler (not just *returns from* the
	  signal handler).  Many platforms use a trampoline for signal return, and
	  that is working fine, but the only platform I'm (Ulrich) aware of that
	  uses a trampoline for signal handler calls is (recent kernels for)
	  PowerPC.  I believe the rationale for using a trampoline here
	  is to improve performance by avoiding unbalancing of the
	  branch predictor's call/return stack.

	  However, on PowerPC the bug is dormant as well as it is hidden
	  by *another* bug that prevents correct unwinding out of the
	  signal trampoline.  This is because the custom CFI for the
	  trampoline uses a register number (VSCR) that is not ever used
	  by compiler-generated CFI, and that particular register is
	  mapped to an invalid number by the current PowerPC DWARF mapper.

	The underlying unwinder bug is exposed by the "new" regression failures
	in gdb.base/sigstep.exp.  These failures were previously masked by
	the fact that GDB was not seeing a valid frame when it tried to unwind
	the frames.  The sigstep.exp test is specifically testing stepping into
	a signal handler.  With the correct DWARF register mapping in place,
	specifically the VSCR mapping, the signal trampoline code now unwinds to a
	valid frame exposing the pre-existing bug in how the signal handler on
	PowerPC works.  The one line change infrun.c fixes the exiting bug in
	the common-code for platforms that use a trampoline to dispatch calls
	to the signal handler by not stopping in the SIGTRAMP_FRAME.

	Detailed description of the DWARF register mapping fix.

	The PowerPC DWARF register mapping is the same for the .eh_frame and
	.debug_frame on Linux.  PowerPC uses different mapping for .eh_frame and
	.debug_frame on other operating systems.  The current GDB support for
	mapping the DWARF registers in rs6000_linux_dwarf2_reg_to_regnum and
	rs6000_adjust_frame_regnum file gdb/rs6000-tdep.c is not correct for Linux.
	The files have some legacy mappings for spe_acc, spefscr, EV which was
	removed from GCC in 2017.

	This patch adds a two new functions rs6000_linux_dwarf2_reg_to_regnum,
	and rs6000_linux_adjust_frame_regnum in file gdb/ppc-linux-tdep.c to handle
	the DWARF register mappings on Linux.  Function
	rs6000_linux_dwarf2_reg_to_regnum is installed for both gdb_dwarf_to_regnum
	and gdbarch_stab_reg_to_regnum since the mappings are the same.

	The ppc_linux_init_abi function in gdb/ppc-linux-tdep.c is updated to
	call set_gdbarch_dwarf2_reg_to_regnum map the new function
	rs6000_linux_dwarf2_reg_to_regnum for the architecture.  Similarly,
	dwarf2_frame_set_adjust_regnum is called to map
	rs6000_linux_adjust_frame_regnum into the architecture.

	Additional detail on the signal handling fix.

	The specific sequence of events for handling a signal on most
	architectures is as follows:

	  1) Some code is running when a signal arrives.
	  2) The kernel handles the signal and dispatches to the handler.
	    ...

	However on PowerPC the sequence of events is:

	  1) Some code is running when a signal arrives.
	  2) The kernel handles the signal and dispatches to the trampoline.
	  3) The trampoline performs a normal function call to the handler.
	      ...

	We want the "nexti" to step into, not over, signal handlers invoked by
	the kernel.  This is the case for most platforms as the kernel puts a
	signal trampoline frame onto the stack to handle proper return after the
	handler.  However, on some platforms such as PowerPC, the kernel actually
	uses a trampoline to handle *invocation* of the handler.  We do not
	want GDB to stop in the SIGTRAMP_FRAME.  The issue is fixed in function
	process_event_stop_test by adding a check that the frame is not a
	SIGTRAMP_FRAME to the if statement to stop in a subroutine call.  This
	prevents GDB from erroneously detecting the trampoline invocation as a
	subroutine call.

	This patch fixes two regression test failures in gdb.base/store.exp.

	The patch then fixes an exposed, dormant, signal handling issue that
	is exposed in the signal handling test gdb.base/sigstep.exp.

	The patch has been tested on Power 8 LE/BE, Power 9 LE/BE, Power 10 with
	no new regressions.  Note, only two of the five failures in store.exp
	are fixed.  The remaining three failures are fixed in a following
	patch.

2023-11-08  Andrew Burgess  <aburgess@redhat.com>

	gdb: call update_thread_list after completing an inferior call
	I noticed that if GDB is using a remote or extended-remote target,
	then, if an inferior call caused a new thread to appear, or for an
	existing thread to exit, then these events are not reported to the
	user.

	The problem is that for these targets GDB relies on a call to
	update_thread_list to learn about changes to the inferior's thread
	list.

	If GDB doesn't pass through the normal stop code then GDB will not
	call update_thread_list, and so will not report changes in the thread
	list.

	This commit adds an additional update_thread_list call, after which
	thread events are correctly reported.

2023-11-08  Andrew Burgess  <aburgess@redhat.com>

	gdb: call update_thread_list for $_inferior_thread_count function
	I noticed that sometimes the value returned by $_inferior_thread_count
	can become out of sync with the actual thread count of the inferior,
	and will disagree with the number of threads reported by 'info
	threads'.  This commit fixes this issue.

	The cause of the problem is that 'info threads' includes a call to
	update_thread_list, this can be seen in print_thread_info_1 in
	thread.c, while $_inferior_thread_count doesn't include a similar
	call, see the function inferior_thread_count_make_value also in
	thread.c.

	Of course, this is only a problem when GDB is running on a target that
	relies on update_thread_list calls to learn about new threads,
	e.g. remote or extended-remote targets.  Native targets generally
	learn about new threads as soon as they appear and will not have this
	problem.

	I ran into this issue when writing a test for the next commit which
	uses inferior function calls to add an remove threads from an
	inferior.  But for testing I've made use of non-stop mode and
	asynchronous inferior execution; by reading the inferior state I can
	know when a new thread has been created, at which point I can print
	$_inferior_thread_count while the inferior is still running.  This is
	important, if I stop the inferior then GDB will pass through an
	update_thread_list call in the normal stop code, which will
	synchronise the thread list, after which $_inferior_thread_count will
	report the correct value.

	With this change in place $_inferior_thread_count is now correct.

	gdb: add a custom command completer for disassemble command
	Add a new command completer function for the disassemble command.
	There are two things that this completion function changes.  First,
	after the previous commit, the new function calls skip_over_slash_fmt,
	which means that hitting tab after entering a /OPT flag now inserts a
	space ready to start typing the address to disassemble at:

	  (gdb) disassemble /r<TAB>
	  (gdb) disassemble /r <CURSOR>

	But also, we now get symbol completion after a /OPT option set,
	previously this would do nothing:

	  (gdb) disassemble /r mai<TAB>

	But now:

	  (gdb) disassemble /r mai<TAB>
	  (gdb) disassemble /r main <CURSOR>

	Which was my main motivation for working on this commit.

	However, I have made a second change in the completion function.
	Currently, the disassemble command calls the generic
	location_completer function, however, the disassemble docs say:

	     Note that the 'disassemble' command's address arguments are specified
	  using expressions in your programming language (*note Expressions:
	  Expressions.), not location specs (*note Location Specifications::).
	  So, for example, if you want to disassemble function 'bar' in file
	  'foo.c', you must type 'disassemble 'foo.c'::bar' and not 'disassemble
	  foo.c:bar'.

	And indeed, if I try:

	  (gdb) disassemble hello.c:main
	  No symbol "hello" in current context.
	  (gdb) disassemble hello.c::main
	  No symbol "hello" in current context.
	  (gdb) disassemble 'hello.c'::main
	  Dump of assembler code for function main:
	  ... snip ...

	But, if I do this:

	  (gdb) disassemble hell<TAB>
	  (gdb) disassemble hello.c:<CURSOR>

	which is a consequence of using the location_completer function.  So
	in this commit, after calling skip_over_slash_fmt, I forward the bulk
	of the disassemble command completion to expression_completer.  Now
	when I try this:

	  (gdb) disassemble hell<TAB>

	gives nothing, which I think is an improvement.  There is one slight
	disappointment, if I do:

	  (gdb) disassemble 'hell<TAB>

	I still get nothing.  I had hoped that this would expand to:
	'hello.c':: but I guess this is a limitation of the current
	expression_completer implementation, however, I don't think this is a
	regression, the previous expansion was just wrong.  Fixing
	expression_completer is out of scope for this commit.

	I've added some disassembler command completion tests, and also a test
	that disassembling using 'FILE'::FUNC syntax works, as I don't think
	that is tested anywhere.

2023-11-08  Andrew Burgess  <aburgess@redhat.com>

	gdb: make skip_over_slash_fmt available outside printcmd.c
	Move the function skip_over_slash_fmt into completer.c, and make it
	extern, with a declaration in completer.h.

	This is a refactor in order to support the next commit.  I've not

	gdb: error if /r and /b are used with disassemble command
	The disassembler gained a new /b flag in this commit:

	  commit d4ce49b7ac077a9882d6a5e689e260300045ca88
	  Date:   Tue Jun 21 20:23:35 2022 +0100

	      gdb: disassembler opcode display formatting

	The /b and /r flags result in the instruction opcodes displayed in
	different formats, so it's not possible to have both at the same
	time.  Currently the /b flag overrides the /r flag.

	We have a similar situation with the /m and /s flags, but here, if the
	user tries to use both flags then they will get an error.

	I think the error is clearer, so in this commit I propose that we add
	an error if /r and /b are both used.

	Obviously this change breaks backwards compatibility.  I don't have a
	compelling argument for why we should make the change beyond my
	feeling that it was a mistake not to add this error from the start,
	and that the new behaviour is better.

	Add minimal thread-safety to BFD
	This patch provides some minimal thread-safety to BFD.

	The BFD client can request thread-safety by providing a lock and
	unlock function.  The globals used during BFD creation (e.g.,
	bfd_id_counter) are then locked, and the file descriptor cache is also
	locked.  A function to clean up any thread-local data is now provided
	for BFD clients.

	aarch64: Add 128-bit system register flags

	Given the shared nature of this file, this change is made necessary
	initially to implement argument validation in the `__arm_rsr128' and

	gdb/arm: remove thumb bit in arm_adjust_breakpoint_address
	When compiling gdb with -fsanitize=address on ARM, I get a crash in test
	gdb.arch/arm-disp-step.exp, reproduced easily with:

	    $ ./gdb -nx -q --data-directory=data-directory testsuite/outputs/gdb.arch/arm-disp-step/arm-disp-step -ex "break *test_call_end"
	    Reading symbols from testsuite/outputs/gdb.arch/arm-disp-step/arm-disp-step...
	    =================================================================
	    ==23295==ERROR: AddressSanitizer: heap-buffer-overflow on address 0xb4a14fd1 at pc 0x01a48871 bp 0xbeab8490 sp 0xbeab8494

	Since it doesn't require running the program, it can be reproduced locally on a
	dev machine other than ARM, after acquiring the test binary.

	The length of the allocate buffer `buf` is 1, and we try to extract an
	integer of size 2 from it.  The length of 1 comes from the subtraction
	`bpaddr - boundary`.  Normally, on ARM, all instructions are aligned on
	a multiple of 2, so it's weird for this subtraction to result in 1.  In
	this case, boundary comes from the result of find_pc_partial_function
	returning 0x549:

	    (gdb) p/x bpaddr
	    $2 = 0x54a
	    (gdb) p/x boundary
	    $3 = 0x549
	    (gdb) p/x bpaddr - boundary
	    $4 = 0x1

	0x549 is the address of the test_call_subr label, 0x548, with the thumb
	bit enabled.  Before doing some math with the address, I think we need
	to strip the thumb bit, like is done elsewhere (for instance for bpaddr
	earlier in the same function).

	I wonder if find_pc_partial_function should do that itself, in order to
	return an address that is suitable for arithmetic.  In any case, that
	would be a change with a broad impact, so for now just fix the issue
	locally.

	After the patch:

	    $ ./gdb -nx -q --data-directory=data-directory testsuite/outputs/gdb.arch/arm-disp-step/arm-disp-step -ex "break *test_call_end"
	    Reading symbols from testsuite/outputs/gdb.arch/arm-disp-step/arm-disp-step...
	    Breakpoint 1 at 0x54a: file /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.arch/arm-disp-step.S, line 103.

	ld/x86: reduce testsuite dependency on system object files
	PR ld/30722
	Tests looking for certain .note-section recorded properties may not
	involve object files from the underlying platform (e.g. via using the C
	compiler for linking): Such object files may themselves have similar
	note sections, and hence they may influence the overall outcome.

	For now convert just the tests known to be affected by crt*.o coming
	with "ISA v3 needed" notes. Eventually other tests ought to be
	converted, too.

	In AIX unused or constant variables are collected as garbage by the linker and in the dwarf dump
	an address with all f's in hexadecimal are assigned. Hence the testcase fails with many failures stating
	it cannot access memory.

	Pre-read DWZ file in DWARF reader
	While working on background reading of DWARF, I came across the
	DWZ-reading code.  This code can query the user (via the debuginfod
	support) -- something that cannot be done off the main thread.

	Looking into it, I realized that this code can be run much earlier,
	avoiding this problem.  Digging a bit deeper, I also found a
	discrepancy here between how the DWARF reader works in "readnow" mode
	as compared to the normal modes.

	This patch cleans this up by trying to read the DWZ file earlier, and
	also by having the DWARF reader convert any exception here into a
	warning.  This unifies the various cases, but also makes it so that
	errors do not prevent gdb from continuing on to the extent possible.

	Regression tested on x86-64 Fedora 38.

	gdbsupport: mark array_view::slice with [[nodiscard]]
	I (almost) had a bug where I did:

	    buffer.slice (...)

	but I meant:

	    buffer = buffer.slice (...)

	The first one does nothing, it creates a new array_view but without
	using it, it's useless.  Mark the slice methods with [[nodiscard]]
	(which is standard C++17) so that error would generate a warning.

	I guess that many functions could be marked as nodiscard, essentially
	function that is pure (doesn't have side-effects).  But this one seems
	particularly easy to mis-use.

	gdbsupport: record and print failed selftest names
	Since "maint selftest" now runs quite a lot of tests (especially in an

	Print the summary before the "Ran %d unit tests, %zu failed\n" line, so
	that that one remains the last line, and the gdb.gdb/unittest.exp

	Within the groups L{B,BU,H,HU,W,WU,D}, S{B,H,W,D}, FL{H,W,D,Q}, and

	[gdb/tdep] Fix nr array elements in ppc64_aggregate_candidate
	On AlmaLinux 9.2 powerpc64le I run into:
	...
	(gdb) PASS: gdb.ada/array_return.exp: continuing to Create_Small_Float_Vector
	finish^M
	Run till exit from #0  pck.create_small_float_vector () at pck.adb:30^M
	0x00000000100022d4 in p () at p.adb:25^M
	25         Vector := Create_Small_Float_Vector;^M
	Value returned is $3 = (2.80259693e-45, 2.80259693e-45)^M
	(gdb) FAIL: gdb.ada/array_return.exp: value printed by finish of Create_Small_Float_Vector
	...
	while this is expected:
	...
	Value returned is $3 = (4.25, 4.25)^M
	...

	The problem is here in ppc64_aggregate_candidate:
	...
			  if (!get_array_bounds (type, &low_bound, &high_bound))
			    return -1;
			  count *= high_bound - low_bound
	...

	The array type (containing 2 elements) is:
	...
	   type Small_Float_Vector is array (1 .. 2) of Float;
	...
	so we have:
	...
	(gdb) p	low_bound
	$1 = 1
	(gdb) p	high_bound
	$2 = 2
	...
	but we calculate the number of elements in the array using
	"high_bound - low_bound", which is 1.

	Consequently, gdb fails to correctly classify the type as a ELFv2 homogeneous
	aggregate.

	Fix this by calculating the number of elements in the array by using
	"high_bound - low_bound + 1" instead.

	Furthermore, high_bound can (in general, though perhaps not here) also be
	smaller than low_bound, so to be safe take that into account as well:
	...
		  LONGEST nr_array_elements = (low_bound > high_bound
					       ? 0
					       : (high_bound - low_bound + 1));
		  count *= nr_array_elements;
	...

	[gdb/symtab] Work around gas PR28629
	When running test-case gdb.tui/tui-layout-asm-short-prog.exp on AlmaLinux 9.2
	ppc64le, I run into:
	...
	FAIL: gdb.tui/tui-layout-asm-short-prog.exp: check asm box contents
	...

	The problem is that we get:
	...
	    7              [ No Assembly Available ]
	...
	because tui_get_begin_asm_address doesn't succeed.

	In more detail, tui_get_begin_asm_address calls:
	...
			    find_line_pc (sal.symtab, sal.line, &addr);
	...
	with:
	...
	(gdb) p *sal.symtab
	$5 = {next = 0x130393c0, m_compunit = 0x130392f0, m_linetable = 0x0,
	  filename = "tui-layout-asm-short-prog.S",
	  filename_for_id = "$gdb/build/gdb/testsuite/tui-layout-asm-short-prog.S",
	  m_language = language_asm, fullname = 0x0}
	(gdb) p sal.line
	$6 = 1
	...

	The problem is the filename_for_id which is the source file prefixed with the
	compilation dir rather than the source dir.

	This is due to faulty debug info generated by gas, PR28629:
	...
	    <1a>   DW_AT_name        : tui-layout-asm-short-prog.S
	    <1e>   DW_AT_comp_dir    : $gdb/build/gdb/testsuite
	    <22>   DW_AT_producer    : GNU AS 2.35.2
	...

	The DW_AT_name is relative, and it's relative to the DW_AT_comp_dir entry,
	making the effective name $gdb/build/gdb/testsuite/tui-layout-asm-short-prog.S.

	The bug is fixed starting version 2.38, where we get instead:
	...
	    <1a>   DW_AT_name        :
	             $gdb/src/gdb/testsuite/gdb.tui/tui-layout-asm-short-prog.S
	    <1e>   DW_AT_comp_dir    : $gdb/build/gdb/testsuite
	    <22>   DW_AT_producer    : GNU AS 2.38
	...

	Work around the faulty debug info by constructing the filename_for_id using
	the second directory from the directory table in the .debug_line header:
	...
	 The Directory Table (offset 0x22, lines 2, columns 1):
	  Entry	Name
	  0	$gdb/build/gdb/testsuite
	  1	$gdb/src/gdb/testsuite/gdb.tui
	...

	Note that the used gas contains a backport of commit 3417bfca676 ("GAS:
	DWARF-5: Ensure that the 0'th entry in the directory table contains the
	current working directory."), because directory 0 is correct.  With the
	unpatched 2.35.2 release the directory 0 entry is incorrect: it's a copy of
	entry 1.

	Add a dwarf assembly test-case that reflects the debug info as generated by
	unpatched gas 2.35.2.

	Tested on x86_64-linux.

	gas: bpf: new test for MOV with C-like numbers ll suffix
	The BPF pseudo-c syntax supports both MOV and LDDW instructions:

	    mov:  r1 = EXPR
	    lddw: r1 = EXPR ll

	Note that the white space between EXPR and `ll' is necessary in order
	to avoid ambiguity with the assembler's support for C-like numerical
	suffixes.  This patch adds a new test to the GAS BPF testsuite to make
	sure that instructions like:

	    r1 = 666ll

	Pre-read .debug_aranges section
	While working on background DWARF reading, I found a race case that I
	tracked down to the handling of the .debug_aranges section.  Currently
	the section data is only read in after the CUs have all been created.
	However, there's no real reason to do this -- it seems fine to read it
	a little earlier, when all the other necessary sections are read in.

	This patch makes this change, and updates the
	read_addrmap_from_aranges API to assert that the section is read in.

	This patch slightly changes the read_addrmap_from_aranges API as well,
	to reject an empty section.  This seems better to me than what the

	gdb/gdbsupport/gdbserver: Require c++17
	This patch proposes to require a C++17 compiler to build gdb /
	gdbsupport / gdbserver.  Before this patch, GDB required a C++11
	compiler.

	The general policy regarding bumping C++ language requirement in GDB (as
	stated in [1]) is:

	    Our general policy is to wait until the oldest compiler that
	    supports C++NN is at least 3 years old.

	    Rationale: We want to ensure reasonably widespread compiler
	    availability, to lower barrier of entry to GDB contributions, and to
	    make it easy for users to easily build new GDB on currently
	    supported stable distributions themselves. 3 years should be
	    sufficient for latest stable releases of distributions to include a
	    compiler for the standard, and/or for new compilers to appear as
	    easily installable optional packages. Requiring everyone to build a
	    compiler first before building GDB, which would happen if we
	    required a too-new compiler, would cause too much inconvenience.

	    See the policy proposal and discussion
	    [here](https://sourceware.org/ml/gdb-patches/2016-10/msg00616.html).

	The first GCC release which with full C++17 support is GCC-9[2],
	released in 2019[3], which is over 4 years ago.  Clang has had C++17
	support since Clang-5[4] released in 2018[5].

	A discussions with many distros showed that a C++17-able compiler is
	always available, meaning that this no hard requirement preventing us to
	require it going forward.

	RISC-V: Clarify the behaviors of SET/ADD/SUB relocations.
	We are used to generate these kinds of relocations by data directives.
	Considering the following example,
	.word (A + 3) - (B + 2)
	The GAS will generate a pair of ADD/SUB for this,
	R_RISCV_ADD, A + 1
	R_RISCV_SUB, 0

	The addend of R_RISCV_SUB will always be zero, and the summary of the
	constants will be stored in the addend of R_RISCV_ADD/SET.  Therefore,
	we can always add the addend of these data relocations when doing relocations.

	But unfortunately, I had heard that if we are using .reloc to generate
	the data relocations will make the relocations failed.  Refer to this,
	.reloc offset, R_RISCV_ADD32, A + 3
	.reloc offset, R_RISCV_SUB32, B + 2
	.word 0
	Then we can get the relocations as follows,
	R_RISCV_ADD, A + 3
	R_RISCV_SUB, B + 2
	Then...  Current LD does the relocation, B - A + 3 + 2, which is wrong
	obviously...

	So first of all, this patch fixes the wrong relocation behavior of
	R_RISCV_SUB* relocations.

	Afterwards, considering the uleb128 direcitve, we will get a pair of
	SET_ULEB128/SUB_ULEB128 relocations for it for now,
	.uleb128 (A + 3) - (B + 2)
	R_RISCV_SET_ULEB128, A + 1
	R_RISCV_SUB_ULEB128, B + 1

	Which looks also wrong obviously, the summary of the constants should only
	be stored into the addend of SET_ULEB128, and the addend of SUB_ULEB128 should
	be zero like other SUB relocations.  But the current LD will still get the right
	relocation values since we only add the addend of SUB_ULEB128 by accident...
	Anyway, this patch also fixes the behaviors above, to make sure that no matter
	using .uleb128 or .reloc directives, we should always get the right values.

	bfd/
		* elfnn-riscv.c (perform_relocation):  Clarify that SUB relocations
		should substract the addend, rather than add.
		(riscv_elf_relocate_section): Since SET_ULEB128 won't go into
		perform_relocation, we should add it's addend here in advance.
	gas/
		* config/tc-riscv.c (riscv_insert_uleb128_fixes): Set the addend of
		SUB_ULEB128 to zero since it should already be added into the addend
		of SET_ULEB128.

	gdb/python: Add new gdb.Value.bytes attribute
	Add a gdb.Value.bytes attribute.  This attribute contains the bytes of
	the value (assuming the complete bytes of the value are available).

	If the bytes of the gdb.Value are not available then accessing this
	attribute raises an exception.

	The bytes object returned from gdb.Value.bytes is cached within GDB so
	that the same bytes object is returned each time.  The bytes object is
	created on-demand though to reduce unnecessary work.

	For some values we can of course obtain the same information by
	reading inferior memory based on gdb.Value.address and
	gdb.Value.type.sizeof, however, not every value is in memory, so we
	don't always have an address.

	The gdb.Value.bytes attribute will convert any value to a bytes
	object, so long as the contents are available.  The value can be one
	created purely in Python code, the value could be in a register,
	or (of course) the value could be in memory.

	The Value.bytes attribute can also be assigned too.  Assigning to this
	attribute is similar to calling Value.assign, the value of the
	underlying value is updated within the inferior.  The value assigned
	to Value.bytes must be a buffer which contains exactly the correct
	number of bytes (i.e. unlike value creation, we don't allow oversized
	buffers).

	To support this assignment like behaviour I've factored out the core
	of valpy_assign.  I've also updated convert_buffer_and_type_to_value
	so that it can (for my use case) check the exact buffer length.

	The restrictions for when the Value.bytes can or cannot be written too
	are exactly the same as for Value.assign.

	gdb: handle main thread exiting during detach
	Overview
	========

	Consider the following situation, GDB is in non-stop mode, the main
	thread is running while a second thread is stopped.  The user has the
	second thread selected as the current thread and asks GDB to detach.
	At the exact moment of detach the main thread exits.

	This situation currently causes crashes, assertion failures, and
	unexpected errors to be reported from GDB for both native and remote
	targets.

	This commit addresses this situation for native and remote targets.
	There are a number of different fixes, but all are required in order
	to get this functionality working correct for native and remote
	targets.

	Native Linux Target
	===================

	For the native Linux target, detaching is handled in the function
	linux_nat_target::detach.  In here we call stop_wait_callback for each
	thread, and it is this callback that will spot that the main thread
	has exited.

	GDB then detaches from everything except the main thread by calling
	detach_callback.

	After this the first problem is this assert:

	  /* Only the initial process should be left right now.  */
	  gdb_assert (num_lwps (pid) == 1);

	The num_lwps call will return 0 as the main thread has exited and all
	of the other threads have now been detached.  I fix this by changing
	the assert to allow for 0 or 1 lwps at this point.  As the 0 case can
	only happen in non-stop mode, the assert becomes:

	  gdb_assert (num_lwps (pid) == 1
		      || (target_is_non_stop_p () && num_lwps (pid) == 0));

	The next problem is that we do:

	  main_lwp = find_lwp_pid (ptid_t (pid));

	and then proceed assuming that main_lwp is not nullptr.  In the case
	that the main thread has exited though, main_lwp will be nullptr.

	However, we only need main_lwp so that GDB can detach from the
	thread.  If the main thread has exited, and GDB has already detached
	from every other thread, then GDB has finished detaching, GDB can skip
	the calls that try to detach from the main thread, and then tell the
	user that the detach was a success.

	For Remote Targets
	==================

	On remote targets there are two problems.

	First is that when the exit occurs during the early phase of the
	detach, we see the stop notification arrive while GDB is removing the
	breakpoints ahead of the detach.  The 'set debug remote on' trace
	looks like this:

	  [remote] Sending packet: $z0,7f1648fe0241,1#35
	  [remote]   Notification received: Stop:W0;process:2a0ac8
	  # At this point an unpatched gdbserver segfaults, and the connection
	  # is broken.  A patched gdbserver continues as below...
	  [remote] Packet received: E01
	  [remote] Sending packet: $z0,7f1648ff00a8,1#68
	  [remote] Packet received: E01
	  [remote] Sending packet: $z0,7f1648ff132f,1#6b
	  [remote] Packet received: E01
	  [remote] Sending packet: $D;2a0ac8#3e
	  [remote] Packet received: E01

	I was originally running into Segmentation Faults, from within
	gdbserver/mem-break.cc, in the function find_gdb_breakpoint.  This
	function calls current_process() and then dereferences the result to
	find the breakpoint list.

	However, in our case, the current process has already exited, and so
	the current_process() call returns nullptr.  At the point of failure,
	the gdbserver backtrace looks like this:

	  #0  0x00000000004190e4 in find_gdb_breakpoint (z_type=48 '0', addr=4198762, kind=1) at ../../src/gdbserver/mem-break.cc:982
	  #1  0x000000000041930d in delete_gdb_breakpoint (z_type=48 '0', addr=4198762, kind=1) at ../../src/gdbserver/mem-break.cc:1093
	  #2  0x000000000042d8db in process_serial_event () at ../../src/gdbserver/server.cc:4372
	  #3  0x000000000042dcab in handle_serial_event (err=0, client_data=0x0) at ../../src/gdbserver/server.cc:4498
	  ...

	The problem is that, as a result non-stop being on, the process
	exiting is only reported back to GDB after the request to remove a
	breakpoint has been sent.  Clearly gdbserver can't actually remove
	this breakpoint -- the process has already exited -- so I think the
	best solution is for gdbserver just to report an error, which is what
	I've done.

	The second problem I ran into was on the gdb side, as the process has
	already exited, but GDB has not yet acknowledged the exit event, the
	detach -- the 'D' packet in the above trace -- fails.  This was being
	reported to the user with a 'Can't detach process' error.  As the test
	actually calls detach from Python code, this error was then becoming a
	Python exception.

	Though clearly the detach has returned an error, and so, maybe, having
	GDB throw an error would be fine, I think in this case, there's a good
	argument that the remote error can be ignored -- if GDB tries to
	detach and gets back an error, and if there's a pending exit event for
	the pid we tried to detach, then just ignore the error and pretend the
	detach worked fine.

	We could possibly check for a pending exit event before sending the
	detach packet, however, I believe that it might be possible (in
	non-stop mode) for the stop notification to arrive after the detach is
	sent, but before gdbserver has started processing the detach.  In this
	case we would still need to check for pending stop events after seeing
	the detach fail, so I figure there's no point having two checks -- we
	just send the detach request, and if it fails, check to see if the
	process has already exited.

	Testing
	=======

	In order to test this issue I needed to ensure that the exit event
	arrives at the same time as the detach call.  The window of
	opportunity for getting the exit to arrive is so small I've never
	managed to trigger this in real use -- I originally spotted this issue
	while working on another patch, which did manage to trigger this
	issue.

	However, if we trigger both the exit and the detach from a single
	Python function then we never return to GDB's event loop, as such GDB
	never processes the exit event, and so the first time GDB gets a
	chance to see the exit is during the detach call.  And so that is the
	approach I've taken for testing this patch.

	gdbserver: don't leak program name in handle_v_run
	I noticed that in handle_v_run (gdbserver/server.cc) we leak
	new_program_name (a string) each time GDB starts an inferior, in the
	case where GDB passes a program name to gdbserver.

	This bug was introduced with this commit:

	  commit 7ab2607f97e5deaeae91018edf3ef5b4255a842c
	  Date:   Wed Apr 13 17:31:02 2022 -0400

	      gdbsupport: make gdb_abspath return an std::string

	When gdbserver receives a program name from GDB, this is first placed
	into a malloc'd buffer within handle_v_run, and this buffer is then
	used in this call:

	  program_path.set (new_program_name);

	Prior to the above commit this call took ownership of the buffer
	passed to it, but now this call uses the buffer to initialise a
	std::string, which copies the buffer contents, leaving ownership with
	the caller.  So now, after this call (in handle_v_run)
	new_program_name still owns a buffer.

	At no point in handle_v_run do we free new_program_name, as a result
	we are leaking the program name each time GDB starts a remote
	inferior.

	I could solve this by adding a 'free' call into handle_v_run, but I'd
	rather automate the memory management.

	So, to this end, I have added a new function in gdbserver/server.cc,
	decode_v_run_arg.  This function takes care of allocating the memory
	buffer and decoding the vRun packet into the buffer, but returns a
	gdb::unique_xmalloc_ptr<char> (or nullptr on error).

	Back in handle_v_run I have converted new_program_name to also be a
	gdb::unique_xmalloc_ptr<char>.

	Now, after we call program_path.set(), the allocated buffer will be
	automatically released when it is no longer needed.

	It is worth highlighting that within the new decode_v_run_arg
	function, I have wrapped the call to hex2bin in a try/catch block.
	The hex2bin function can throw an exception if it encounters an
	invalid (non-hex) character.  Back in handle_v_run, we have a local
	argument new_argv, which is of type std::vector<char *>.  Each
	'char *' in this vector is a malloc'd buffer.  If we allow
	hex2bin to throw an exception and don't catch it in either
	decode_v_run_arg or handle_v_run then we are going to leak memory from
	new_argv.

	I chose to catch the exception in decode_v_run_arg, this seemed
	cleanest, but I'm not sure it really matters, so long as the exception
	is caught before we leave handle_v_run.  I am working on a patch that
	changes new_argv to automatically manage its memory, but that isn't
	ready for posting yet.  I think what I have here would be fine if my
	follow on patch never arrives.

	Additionally, within the handle_v_run loop I have changed an
	assignment of nullptr to new_program_name into an assert.  Previously,
	the assignment could only trigger on the first iteration of the loop,
	if we had no new program name to assign.  However, new_program_name
	always starts as nullptr, so, on the first loop iteration, if we have
	nothing to assign to new_program_name, its value must already be
	nullptr.

	There should be no user visible changes after this commit.

	following the same concept of adding a %cs segment override prefix.

	Also re-use patterns when possible and correct comments as applicable.

	x86: i686 != PentiumPro
	The two are distinct in opcodes/, distinguished precisely by CpuNOP
	that's relevant in i386_generate_nops(), yet the function has the PPro

	cpu_arch[] had a wrong entry for i686.

2023-10-23  Jan Beulich  <jbeulich@suse.com>

	x86: respect ".arch nonop" when selecting which NOPs to emit
	Making GENERIC64 a special case was never correct; prior to the
	generalization of ".arch .no*" to cover all ISA extensions other
	processor families supporting long NOPs should have been covered as
	well. When introducing ".arch .nonops" (among others) it wasn't
	apparent that a hidden implication of .cpunop not being possible to
	separately turn off existed here. Seeing that the two large case label
	blocks in the 2nd switch() already had identical behavior, simply
	collapse all of the (useful) case labels into a single "default" one.

	x86: don't use operand size override with NOP in 16-bit code
	Since we don't key the NOP selection to user-controlled properties, we
	may not use i386 features; otherwise we would violate a possible .arch
	directive restricting ISA to pre-386.

	x86: don't use 32-bit LEA as NOP surrogate in 64-bit code
	Except for the shared 1- and 2-byte cases, the LEA uses corrupt %rsi
	(by zero-extending %esi to %rsi). Introduce separate 64-bit patterns
	which keep %rsi intact.

	x86: i386_generate_nops() may not derive decisions from global variables
	What matters is what was in effect at the time the original directive
	was issued. Later changes to global state (bitness or ISA) must not
	affect what code is generated.

	x86: record flag_code in tc_frag_data
	The recorded value, and not the global variable, will want using in
	TC_FRAG_INIT(). The so far file scope variable therefore needs to become
	external, to be accessible there.

	bfd-in2.h BFD_RELOC_* comments
	I noticed the regenerated BFD_RELOC_MICROBLAZE_32_NONE comment didn't
	match that committed to bfd-in2.h, and was just going to regen
	bfd-in2.h but then decided to do something about the silly formatting
	of these comments in bfd-in2.h.  eg. the BFD_RELOC_MICROBLAZE_32_NONE
	comment:

	-/* This is a 32 bit reloc that stores the 32 bit pc relative
	-value in two words (with an imm instruction).No relocation is

	+  /* This is a 32 bit reloc that stores the 32 bit pc relative value in
	+     two words (with an imm instruction).  No relocation is done here -
	+     only used for relaxing.  */
	   BFD_RELOC_MICROBLAZE_32_NONE,

	You'll notice how the second and third line of the original comment
	aren't indented properly relative to the first line, and the whole
	comment needs to be indented to match the code.

	I've also edited reloc.c ENUMDOC paragraphs.  Some of these had excess
	indentation, presumably in an attempt to properly indent bfd-in2.h
	comments but that fails due to chew.c removing leading whitespace
	early by skip_white_and_stars.  COMMENT was used in reloc.c to add
	extra blank lines in bfd-in2.h.  I've removed them too as I don't
	think they add anything to readability of that file.  (Perhaps more
	usefully, they also add blank lines to libbfd.h separating relocs for
	one target from others, but this isn't done consistently.)

	gdb: fix owner passed to remove_target_sections in clear_solib
	Commit 8971d2788e7 ("gdb: link so_list using intrusive_list") introduced
	a bug in clear_solib.  Instead of passing an `so_list *` to
	remove_target_sections, it passed an `so_list **`.  This was not caught
	by the compiler, because remove_target_sections takes a `void *` as the
	"owner", so you can pass it any pointer and it won't complain.

	This happened because I previously had a patch to change the type of the
	disposer parameter to be a reference rather than a pointer, so had to
	change `so` to `&so`.  When dropping that patch, I forgot to revert this
	bit and / or it got re-introduced when handling subsequent merge
	conflicts.  And I didn't properly retest.

	Fix that, but try to make things less error prone.  Add a union to
	represent the possible owner kinds for a target_section.  Trying to pass
	a pointer to another type than those will not compile.

	[gdb/cli] Allow source-highlight to autodetect language
	Currently when gdb asks the source-highlight library to highlight a file, it
	tells it what language file to use.

	For instance, if gdb learns from the debug info that the file is language_c,
	the language file "c.lang" is used.  This mapping is hardcoded in
	get_language_name.

	However, if gdb doesn't know what language file to use, it falls back to using
	python pygments, and in absence of that, unhighlighted source text.

	In the case of python pygments, it autodetects which language to use based on
	the file name.

	Add the same capability when using the source-highlight library.

	Tested on x86_64-linux.

	Verified that it works by:
	- making get_language_name return nullptr for language_c, and
	- checking that source-highlight still manages to highlight a hello world.

	libctf: fix creation-time parent/child dict confusions
	The fixes applied a few years ago to resolve confusions between parent and
	child dicts at lookup time also apply in various forms to creation.  In
	general, if you have a type in a parent dict ctf_imported into a child and
	you do something to it, and the parent dict is writable (created via
	ctf_create, not opened via ctf_open*) it should work just the same to make
	changes to that type via a child dict as it does to make the change
	to the parent dict directly -- and nothing you're prohibited from doing
	to the parent dict when done directly should be allowed just because
	you're doing it via a child.

	Specifically, the following don't work when doing things from the child, but
	should:

	 - adding a member of a type in the parent to a struct or union in the
	   parent via ctf_add_member or ctf_add_member_offset: this yields
	   ECTF_BADID

	 - adding a member of a type in the parent to a struct or union in the
	   parent via ctf_add_member_encoded: this dumps core (!).

	 - adding an enumerand to an enumerator in the parent: this yields
	   ECTF_BADID

	 - setting the properties of an array in the parent via ctf_set_array;
	   this yields ECTF_BADID

	Relatedly, some things work when doing things via a child that should fail,
	yielding a CTF dictionary with invalid content (readable, but meaningless):
	in particular, you can add a child type to a struct in the parent via
	any of the ctf_add_member* family and nothing complains at all, even though
	you should never be able to add references to children to parents (since any
	given parent can be associated with many different children).

	A family of tests is added to check each of these cases independently, since
	some can result in coredumps and it would be nice to test the other cases
	even if some dump core.  They use a common library to do all the actual
	work.  The set of affected API calls was determined by code inspection
	(auditing all calls to ctf_dtd_lookup): it's possible that I missed a few,
	but I doubt it, since other cases use ctf_lookup* functions, which already
	climb to the parent where appropriate.

	gdb: remove lm_info_vector typedef

	gdb: make solib-rocm not use so_list internally
	Same rationale as the previous patch, but for solib-rocm.

	 - Introduce rocm_so, which is a name a unique_name (see comment in

	   lm_info_svr4.
	 - Change the internal lists from so_list lists to vectors of rocm_so.

	gdb: make solib-svr4 not use so_list internally
	A subsequent patch makes use of non-trivial types in struct so_list.
	This trips on the fact that svr4_copy_library_list uses memcpy to copy
	so_list objects:

	      so_list *newobj = new so_list;
	      memcpy (newobj, src, sizeof (struct so_list));

	solib-svr4 maintains lists of so_list objects in its own internal data
	structures.  When requested to return a list of so_list objects (through
	target_so_ops::current_sos), it duplicates the internal so_list lists,
	using memcpy.  When changing so_list to make it non-trivial, we would
	need to replace this use of memcpy somehow.  That would mean making
	so_list copyable, with all the complexity that entails, just to satisfy
	this internal usage of solib-svr4 (and solib-rocm, which does the same).

	Change solib-svr4 to use its own data type for its internal lists.  The
	use of so_list is a bit overkill anyway, as most fields of so_list are
	irrelevant for this internal use.

	 - Introduce svr4_so, which contains just an std::string for the name
	   and a unique_ptr for the lm_info.
	 - Change the internal so_list lists to be std::vector<svr4_so>.  Vector
	   seems like a good choice for this, we don't need to insert/remove
	   elements in the middle of these internal lists.
	 - Remove svr4_free_library_list, free_solib_lists and ~svr4_info, as
	   everything is managed automatically now.
	 - Replace svr4_copy_library_list (which duplicated internal lists in
	   order to return them to the core) with so_list_from_svr4_sos, which
	   creates an so_list list from a vector of svr4_so.
	 - Generalize svr4_same a bit, because find_debug_base_for_solib now
	   needs to compare an so_list and an svr4_so to see if they are the
	   same.

	Have DAP handle non-Value results from 'children'
	A pretty-printer's 'children' method may return values other than a
	gdb.Value -- it may return any value that can be converted to a
	gdb.Value.

	I noticed that this case did not work for DAP.  This patch fixes the

	Handle gdb.LazyString in DAP
	Andry pointed out that the DAP code did not properly handle
	gdb.LazyString results from a pretty-printer, yielding:

	    TypeError: Object of type LazyString is not JSON serializable

	This patch fixes the problem, partly with a small patch in varref.py,
	but mainly by implementing tp_str for LazyString.

	Fix register-setting response from DAP
	Andry noticed that given a DAP setExpression request, where the
	expression to set is a register, DAP will return the wrong value -- it
	will return the old value, not the updated one.

	This happens because gdb.Value.assign (which was recently added for
	DAP) does not update the value.

	In this patch, I chose to have the assign method update the Value
	in-place.  It's also possible to have it return a new value, but this
	didn't seem very useful to me.

	[gdb/symtab] Work around PR gas/29517
	When using glibc debuginfo generated with gas 2.39, we run into PR gas/29517:
	...
	$ gdb -q -batch a.out -ex start -ex "p (char *)strstr (\"haha\", \"ah\")"
	Temporary breakpoint 1 at 0x40051b: file hello.c, line 6.

	Temporary breakpoint 1, main () at hello.c:6
	6	  printf ("hello\n");
	Invalid cast.
	...
	while without glibc debuginfo installed we get the expected result:
	...
	$n = 0x7ffff7daa1b1 "aha"
	...
	and likewise with glibc debuginfo generated with gas 2.40.

	The strstr ifunc resolves to __strstr_sse2_unaligned.  The problem is that gas
	generates dwarf that states that the return type is void:
	...
	<1><3e1e58>: Abbrev Number: 2 (DW_TAG_subprogram)
	    <3e1e59>   DW_AT_name        : __strstr_sse2_unaligned
	    <3e1e5d>   DW_AT_external    : 1
	    <3e1e5e>   DW_AT_low_pc      : 0xbbd2e
	    <3e1e66>   DW_AT_high_pc     : 0xbc1c3
	...
	while the return type should be a DW_TAG_unspecified_type, as is the case
	with gas 2.40.

	We can still use the workaround of casting to another function type for both
	__strstr_sse2_unaligned:
	...
	(gdb) p ((char * (*) (const char *, const char *))__strstr_sse2_unaligned) \
	  ("haha", "ah")
	$n = 0x7ffff7daa211 "aha"
	...
	and strstr (which requires using *strstr to dereference the ifunc before we
	cast):
	...
	gdb) p ((char * (*) (const char *, const char *))*strstr) ("haha", "ah")
	$n = 0x7ffff7daa251 "aha"
	...
	but that's a bit cumbersome to use.

	Work around this in the dwarf reader, such that we have instead:
	...
	(gdb) p (char *)strstr ("haha", "ah")
	$n = 0x7ffff7daa1b1 "aha"
	...

	This also requires fixing producer_is_gcc to stop returning true for
	producer "GNU AS 2.39.0".

	Tested on x86_64-linux.

	Only allow closure lookup by address if there are threads displaced-stepping
	Since commit 1e5ccb9c5ff4fd8ade4a8694676f99f4abf2d679, we have an assertion in
	displaced_step_buffers::copy_insn_closure_by_addr that makes sure a closure
	is available whenever we have a match between the provided address argument and
	the buffer address.

	That is fine, but the report in PR30872 shows this assertion triggering when
	it really shouldn't. After some investigation, here's what I found out.

	The 32-bit Arm architecture is the only one that calls
	gdbarch_displaced_step_copy_insn_closure_by_addr directly, and that's because
	32-bit Arm needs to figure out the thumb state of the original instruction
	that we displaced-stepped through the displaced-step buffer.

	Before the assertion was put in place by commit
	1e5ccb9c5ff4fd8ade4a8694676f99f4abf2d679, there was the possibility of
	getting nullptr back, which meant we were not doing a displaced-stepping
	operation.

	Now, with the assertion in place, this is running into issues.

	It looks like displaced_step_buffers::copy_insn_closure_by_addr is
	being used to return a couple different answers depending on the
	state we're in:

	1 - If we are actively displaced-stepping, then copy_insn_closure_by_addr
	is supposed to return a valid closure for us, so we can determine the
	thumb mode.

	2 - If we are not actively displaced-stepping, then copy_insn_closure_by_addr
	should return nullptr to signal that there isn't any displaced-step buffers
	in use, because we don't have a valid closure (but we should always have
	this).

	Since the displaced-step buffers are always allocated, but not always used,
	that means the buffers will always contain data. In particular, the buffer
	addr field cannot be used to determine if the buffer is active or not.

	For instance, we cannot set the buffer addr field to 0x0, as that can be a
	valid PC in some cases.

	My understanding is that the current_thread field should be a good candidate
	to signal that a particular displaced-step buffer is active or not. If it is
	nullptr, we have no threads using that buffer to displaced-step.  Otherwise,
	it is an active buffer in use by a particular thread.

	The following fix modifies the displaced_step_buffers::copy_insn_closure_by_addr
	function so we only attempt to return a closure if the buffer has an assigned
	current_thread and if the buffer address matches the address argument.

	Alternatively, I think we could use a function to answer the question of
	whether we're actively displaced-stepping (so we have an active buffer) or
	not.

	I've also added a testcase that exercises the problem. It should reproduce
	reliably on Arm, as that is the only architecture that faces this problem
	at the moment.

	Regression-tested on Ubuntu 20.04. OK?

	gdb: replace architecture_changed with new_architecture observer
	This commit replaces the architecture_changed observer with a
	new_architecture observer.

	Currently the only user of the architecture_changed observer is the
	Python code, which uses this observer to register the Python unwinder
	with the architecture.

	The problem is that the architecture_changed observer is triggered
	from inferior::set_arch(), which only sees the inferior-wide gdbarch
	value.  For targets that use thread-specific architectures, these
	never trigger the architecture_changed observer, and so never have the
	Python unwinder registered with them.

	When it comes to unwinding GDB makes use of the frame's gdbarch, which
	is based on the thread's regcache gdbarch, which is set in
	get_thread_regcache to the value returned from
	target_thread_architecture, which is not always the inferiors gdbarch
	value, it might be a thread-specific gdbarch which has not passed
	through inferior::set_arch().

	The new_architecture observer will be triggered from
	gdbarch_find_by_info, whenever a new gdbarch is created and
	initialised.  As GDB caches and reuses gdbarch values, we should
	expect to see each new architecture trigger the new_architecture
	observer just once.

	After this commit, targets that make use of thread-specific
	architectures should be able to make use of Python unwinders.

	As I don't have access to a machine that makes use of thread-specific
	architectures right now, I asked Luis to confirm that an AArch64
	target that uses SVE/SME can't use the Python unwinders in threads
	that are using a thread-specific architectures, and he confirmed that
	this is indeed the case, see this discussion:

	bfd: add new bfd_cache_size() function
	In GDB we have a problem with the BFD cache.

	As GDB runs for a potentially extended period of time, if the BFD
	cache holds a file descriptor for an open on-disk file, this can, on
	some targets (e.g. Win32) prevent the OS writing to the file.

	This might, for example, prevent a user from recompiling their
	executable as GDB is (via the BFD cache) holding an open reference to
	that file.

	Another problem, relates to bfd_stat, for BFDs that are using the BFD
	cache (i.e. they call cache_bstat to implement bfd_stat).  The
	cache_bstat function finds the BFD in the cache, opening the file if
	needed, and then uses fstat on the open file descriptor.

	What this means is that, if the on-disk file changes, but the cache
	was holding an open reference to the file, the bfd_stat will return
	the 'struct stat' for the old file, not the new file.

	Now, for this second problem, we might be tempted to make use of an
	actual stat call, instead of calling bfd_stat, however, this isn't
	ideal as we have some BFDs that use a custom iovec, and implement the
	various functions over GDB's remote protocol.  By using bfd_stat we
	can have a single call that should work for both local files, and for
	remote files.

	To solve both of these problems GDB has calls to bfd_cache_close_all
	sprinkled around its code base.  And in theory this should work fine.

	However, I recently ran into a case where we had missed a
	bfd_cache_close_all call, and as a result some BFDs were held open.
	This caused a bfd_stat call to return an unexpected result (old file
	vs new file).

	What I'd like is some way within GDB that I can do:

	  gdb_assert ( /* Nothing is held open in the cache.  */ );

	As this would allow GDB to quickly identify when we've missed some
	bfd_cache_close_all calls.

	And so, to support this, I would like to add a new bfd_cache_size
	function.  This function returns an integer, which is the number of
	open files in the cache.  I can then start adding:

	  gdb_assert (bfd_cache_size() == 0);

	to GDB in some strategic spots, and start fixing all of the missing
	bfd_cache_close_all calls that crop up as a result.

	bfd/cache: change type used to track cached BFDs from int to unsigned
	Within bfd/cache.c change the type for max_open_files and open_files
	variables from int to unsigned.  As a consequence of this, the return
	type for bfd_cache_max_open() is also changed from int to unsigned.

	Within bfd_cache_max_open I've left the local 'max' variable as an
	int, this should ensure that if the sysconf call fails, and returns
	-1, then the computed max value will be less than 10, which means
	max_open_files will be set to 10.  If 'max' was changed to unsigned
	then, should the sysconf call fail, we'd end up with max becoming a
	very large positive number ... which is clearly not what we want.

	And, while I was auditing how open_files is used, I added an assert
	within bfd_cache_delete to ensure that we don't try to reduce
	open_files below zero.

	There should be no user visible change with this commit.

	[RFA] Fix for mcore simulator
	I was looking for cases where a GCC patch under evaluation would cause test
	results to change.  Quite surprisingly the mcore-elf port showed test
	differences.   After a fair amount of digging my conclusion was the sequences
	before/after the patch should have been semantically the same.

	Of course if the code is supposed to behave the same, then that points to
	problems elsewhere (assembler, linker, simulator).  Sure enough the mcore
	simulator was mis-handling the sign extension instructions.  The simulator
	implementation of sextb is via paired shift-by-24 operations. Similarly the
	simulator implements sexth via paired shift-by-16 operations.

	The temporary holding the value was declared as a "long" thus this approach
	worked fine for hosts with a 32 bit wide long and failed miserably for hosts
	with a 64 bit wide long.

	This patch makes the shift count automatically adjust based on the size of the
	temporary.  It includes a simple test for sextb and sexth.  I have _not_ done a
	full audit of the mcore simulator for more 32->64 bit issues.

	This also fixes 443 execution tests in the GCC testsuite

	The root cause is related with a struct containing floating-point

	    wide, it is passed in an FAR if available.
	(2) Structure consists of two floating-point members both within FRLEN

	gdb: add assertion when marking the remote async flag
	As reported in bug 30630 [1], we hit a case where the remote target's
	async flag is marked while the target is not configured (yet) to work
	async.  This should not happen.  It is caught thanks to this assert in
	remote_target::wait:

	    /* Start by clearing the flag that asks for our wait method to be called,
	       we'll mark it again at the end if needed.  If the target is not in
	       async mode then the async token should not be marked.  */
	    if (target_is_async_p ())
	      rs->clear_async_event_handler ();
	    else
	      gdb_assert (!rs->async_event_handler_marked ());

	This is helpful, but I think that we could have caught the problem earlier than
	that, at the moment we marked the handler.  Catching problems earlier
	makes them easier to debug.

	gdb: remove target_gdbarch
	This function is just a wrapper around the current inferior's gdbarch.
	I find that having that wrapper just obscures where the arch is coming
	from, and that it's often used as "I don't know which arch to use so
	I'll use this magical target_gdbarch function that gets me an arch" when
	the arch should in fact come from something in the context (a thread,
	objfile, symbol, etc).  I think that removing it and inlining
	`current_inferior ()->arch ()` everywhere will make it a bit clearer
	where that arch comes from and will trigger people into reflecting
	whether this is the right place to get the arch or not.

	[gdb/symtab] Add name_of_main and language_of_main to the DWARF index
	This patch adds a new section to the DWARF index containing the name
	and the language of the main function symbol, gathered from
	`cooked_index::get_main`, if available. Currently, for lack of a better name,
	this section is called the "shortcut table". The way this name is both saved and
	applied upon an index being loaded in mirrors how it is done in
	`cooked_index_functions`, more specifically, the full name of the main function
	symbol is saved and `set_objfile_main_name` is used to apply it after it is
	loaded.

	The main use case for this patch is in improving startup times when dealing with
	large binaries. Currently, when an index is used, GDB has to expand symtabs
	until it finds out what the language of the main function symbol is. For some
	large executables, this may take a considerable amount of time to complete,
	slowing down startup. This patch bypasses that operation by having both the name
	and language of the main function symbol be provided ahead of time by the index.

	In my testing (a binary with about 1.8GB worth of DWARF data) this change brings
	startup time down from about 34 seconds to about 1.5 seconds.

	When testing the patch with target board cc-with-gdb-index, test-case
	gdb.fortran/nested-funcs-2.exp starts failing, but this is due to a
	pre-existing issue, filed as PR symtab/30946.

	process-dies-while-detaching.exp: Exit early if GDB misses sync breakpoint
	I'm seeing a lot of variability in the failures of
	gdb.threads/process-dies-while-detaching.exp on aarch64-linux.  On this
	platform, a problem yet to be investigated causes GDB to miss the _exit
	breakpoint.  What happens next is random because after missing that
	breakpoint, GDB is out of sync with the inferior.  This causes the tests
	following that point in the testcase to fail in a random way.

	In this scenario it's better to exit the testcase early to avoid random
	results in the testsuite.

	We are relying on gdb_continue_to_breakpoint to return the result of
	gdb_test_multiple.  This is already the case because in Tcl the return
	value of a function is the return value of the last command it runs.  But
	change gdb_continue_to_breakpoint to explicitly return this value, to make

	gdbserver: cleanup in handle_v_run
	After the previous commit there is now a redundant string copy in
	handle_v_run, this commit cleans that up.

	There should be no functional change after this commit.

	During review I was pointed to this older series:

	  https://inbox.sourceware.org/gdb-patches/20211022071933.3478427-1-m.weghorn@posteo.de/

	which also includes this fix as part of a larger set of changes.  I'm
	giving a Co-Authored-By credit to the author of that original series.
	I believe this smaller fix brings some benefits on its own, though the
	original series does offer additional improvements.  Once this is
	merged I'll take a look at rebasing and resubmitting the original series.

	gdbserver: handle newlines in inferior arguments
	Similarly to how single quotes were mishandled, which was fixed two
	commits ago, this commit fixes handling of newlines in arguments
	passed to gdbserver.

	We already had a test that covered this, gdb.base/args.exp, which,
	when run with the native-extended-gdbserver board contained several
	KFAIL covering this situation.

	In this commit I remove the unnecessary, attempt to quote incoming
	newlines within arguments, and do some minimal cleanup of the related
	code.  There is additional cleanup that can be done, but I'm leaving
	that for the next commit.

	Then I've removed the KFAIL from the test case, and performed some
	minimal cleanup there too.

	After this commit the gdb.base/args.exp is 100% passing with the
	native-extended-gdbserver board file.

	gdbserver: fix handling of trailing empty argument
	When I posted the previous patch for review Andreas Schwab pointed out
	that passing a trailing empty argument also doesn't work.

	The fix for this is in the same area of code as the previous patch,
	but is sufficiently different that I felt it deserved a patch of its
	own.

	I noticed that passing arguments containing single quotes to gdbserver
	didn't work correctly:

	  gdb -ex 'set sysroot' --args /tmp/show-args
	  Reading symbols from /tmp/show-args...
	  (gdb) target extended-remote | gdbserver --once --multi - /tmp/show-args
	  Remote debugging using | gdbserver --once --multi - /tmp/show-args
	  stdin/stdout redirected
	  Process /tmp/show-args created; pid = 176054
	  Remote debugging using stdio
	  Reading symbols from /lib64/ld-linux-x86-64.so.2...
	  (No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
	  0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
	  (gdb) set args abc ""
	  (gdb) run
	  The program being debugged has been started already.
	  Start it from the beginning? (y or n) y
	  Starting program: /tmp/show-args \'
	  stdin/stdout redirected
	  Process /tmp/show-args created; pid = 176088
	  2 args are:
	    /tmp/show-args
	    abc
	  Done.
	  [Inferior 1 (process 176088) exited normally]
	  (gdb) target native
	  Done.  Use the "run" command to start a process.
	  (gdb) run
	  Starting program: /tmp/show-args \'
	  2 args are:
	    /tmp/show-args
	    abc

	  Done.
	  [Inferior 1 (process 176095) exited normally]
	  (gdb) q

	The 'shows-args' program used here just prints the arguments passed to
	the inferior.

	Notice that when starting the inferior using the extended-remote
	target there is only a single argument 'abc', while when using the
	native target there is a second argument, the blank line, representing
	the empty argument.

	The problem here is that the vRun packet coming from GDB looks like
	this (I've removing the trailing checksum):

	  $vRun;PROGRAM_NAME;616263;

	If we compare this to a packet with only a single argument and no
	trailing empty argument:

	  $vRun;PROGRAM_NAME;616263

	Notice the lack of the trailing ';' character here.

	The problem is that gdbserver processes this string in a loop.  At
	each point we maintain a pointer to the character just after a ';',
	and then we process everything up to either the next ';' character, or
	to the end of the string.

	We break out of this loop when the character we start with (in that
	loop iteration) is the null-character.  This means in the trailing
	empty argument case, we abort the loop before doing anything with the
	empty argument.

	In this commit I've updated the loop, we now break out using a 'break'
	statement at the end of the loop if the (sub-)string we just processed
	was empty, with this change we now notice the trailing empty
	argument.

	I've updated the test case to cover this issue.

	gdbserver: fix handling of single quote arguments
	I noticed that passing arguments containing single quotes to gdbserver
	didn't work correctly:

	  Reading symbols from /tmp/show-args...
	  (gdb) target extended-remote | gdbserver --once --multi - /tmp/show-args

	  (gdb) set args \'
	  (gdb) r
	  The program being debugged has been started already.
	  Start it from the beginning? (y or n) y
	  Starting program: /tmp/show-args \'

	    /tmp/show-args
	    '
	  Done.
	  [Inferior 1 (process 176095) exited normally]
	  (gdb) q

	The 'shows-args' program used here just prints the arguments passed to
	the inferior.

	Notice that when starting the inferior using the extended-remote
	target the second argument is "\'", while when running using native
	target the argument is "'".  The second of these is correct, the \'
	used with the "set args" command is just to show GDB that the single
	quote is not opening an argument string.

	It turns out that the extra backslash is injected on the gdbserver
	side when gdbserver processes the arguments that GDB passes it, the
	code that does this was added as part of this much larger commit:

	  commit 2090129c36c7e582943b7d300968d19b46160d84
	  Date:   Thu Dec 22 21:11:11 2016 -0500

	      Share fork_inferior et al with gdbserver

	In this commit I propose removing the specific code that adds what I
	believe is a stray backslash.  I've extended an existing test to cover
	this case, and I now see identical behaviour when using an
	extended-remote target as with the native target.

	This partially fixes PR gdb/27989, though there are still some issues
	with newline handling which I'll address in a later commit.

	During review I was pointed to this older series:

	  https://inbox.sourceware.org/gdb-patches/20211022071933.3478427-1-m.weghorn@posteo.de/

	which also includes this fix as part of a larger set of changes.  I'm
	giving a Co-Authored-By credit to the author of that original series.
	I believe this smaller fix brings some benefits on its own, though the
	original series does offer additional improvements.  Once this is

	gdb/configure.ac: Add option --with-additional-debug-dirs
	If you want to install GDB in a custom prefix, have it look for debug info
	in that prefix but also in the distro's default location (typically,
	/usr/lib/debug) and run the GDB testsuite before doing "make install", you
	have a bit of a problem:

	Configuring GDB with '--prefix=$PREFIX' sets the GDB 'debug-file-directory'
	parameter to $PREFIX/lib/debug.  Unfortunately this precludes GDB from
	looking for distro-installed debug info in /usr/lib/debug.  For regular GDB
	use you could set debug-file-directory to $PREFIX:/usr/lib/debug in
	$PREFIX/etc/gdbinit so that GDB will look in both places, but if you want
	to run the testsuite then that doesn't help because in that case GDB runs
	with the '-nx' option.

	There's the configure option '--with-separate-debug-dir' to set the default
	value for 'debug-file-directory', but it accepts only one directory and not
	a list.  I considered modifying it to accept a list, but it's not obvious
	how to do that because its value is also used by BFD, as well as processed
	for "relocatability".

	I thought it was simpler to add a new option to specify a list of
	additional directories that will be appended to the debug-file-directory
	setting.

	[gdb/go] Handle v3 go_0 mangled prefix
	With gcc-10 we have:
	...
	(gdb) break package2.Foo^M
	Breakpoint 2 at 0x402563: file package2.go, line 5.^M
	(gdb) PASS: gdb.go/package.exp: setting breakpoint 1
	...
	but with gcc-11:
	...
	gdb) break package2.Foo^M
	Function "package2.Foo" not defined.^M
	Make breakpoint pending on future shared library load? (y or [n]) n^M
	(gdb) FAIL: gdb.go/package.exp: gdb_breakpoint: set breakpoint at package2.Foo
	...

	In the gcc-10 case, though the exec contains dwarf, it's not used to set the
	breakpoint (which is an independent problem, filed as PR go/30941), instead
	the minimal symbol information is used.

	The minimal symbol information changed between gcc-10 and gcc-11:
	...
	$ nm a.out.10 | grep Foo
	000000000040370d T go.package2.Foo
	0000000000404e50 R go.package2.Foo..f
	$ nm a.out.11 | grep Foo
	0000000000403857 T go_0package2.Foo
	0000000000405030 R go_0package2.Foo..f
	...

	A new v3 mangling scheme was used.  The mangling schemes define a separator
	character and mangling character:
	- for v2, dot is used both as separator character and mangling character, and
	- for v3, dot is used as separator character and underscore as mangling
	  character.

	For more details, see [1] and [2].

	In v3, "_0" demangles to ".". [ See gcc commit a01dda3c23b ("compiler, libgo:
	change mangling scheme"), function Special_char_code::Special_char_code. ]

	Handle the new go_0 prefix in unpack_mangled_go_symbol, which fixes the
	test-case.

	Note that this doesn't fix this regression:
	...
	$ gccgo-10 package2.go -c -g0
	$ gccgo-10 package1.go package2.o -g0
	$ gdb -q -batch a.out -ex "break go.package2.Foo"
	Breakpoint 1 at 0x40370d
	$ gccgo-11 package2.go -c -g0
	$ gccgo-11 package1.go package2.o -g0
	$ gdb -q -batch a.out -ex "break go.package2.Foo"
	Function "go.package2.Foo" not defined.
	...

	With gcc-10, we set a breakpoint on the mangled minimal symbol.  That
	one has simply changed for gcc-11, so it's equivalent to using:
	...
	$ gdb -q -batch a.out -ex "break go_0package2.Foo"
	Breakpoint 1 at 0x403857
	...
	which does work.

	Tested on x86_64-linux:
	- openSUSE Leap 15.4, using gccgo-7,
	- openSUSE Tumbleweed, using gccgo-13.

	gdb: add all_objfiles_removed observer
	The new_objfile observer is currently used to indicate both when a new
	objfile is added to program space (when passed non-nullptr) and when all
	objfiles of a program space were just removed (when passed nullptr).
	I think this is confusing (and Andrew apparently thinks so too [1]).
	Add a new "all_objfiles_removed" observer to remove the second role from
	"new_objfile".

	Some existing users of new_objfile do nothing if the passed objfile is
	nullptr.  For them, we can simply drop the nullptr check.  For others,
	add a new all_objfiles_removed callback, and refactor things a bit to
	keep the existing behavior as much as possible.

	Some callbacks relied on current_program_space, and following
	the refactoring now use either objfile->pspace or the pspace passed to
	all_objfiles_removed.  I think this should be relatively safe, and in
	general a step in the right direction.

	On the notify side, I found only one call site to change from
	new_objfile to all_objfiles_removed, in clear_symtab_users.  It is not
	entirely clear to me that this is entirely correct.  clear_symtab_users
	appears to be called in spots that don't remove all objfiles
	(functions finish_new_objfile, remove_symbol_file_command, reread_symbols,
	do_module_cleanups).  But I think that this patch at least makes the
	current code clearer.

	gdb: fix auxv cache clearing from new_objfile observer
	It was pointed out on the mailing list that a recently added
	test (gdb.python/py-progspace-events.exp) was failing when run with
	the native-extended-gdbserver board.  This test was added with this
	commit:

	  commit 59912fb2d22f8a4bb0862487f12a5cc65b6a013f
	  Date:   Tue Sep 19 11:45:36 2023 +0100

	      gdb: add Python events for program space addition and removal

	It turns out though that the test is failing due to a existing bug
	in GDB, the new test just exposes the problem.  Additionally, the
	failure really doesn't even rely on the new functionality added in the
	above commit.  I reduced the test to a simple set of steps that
	reproduced the failure and tested against GDB 13, and the test passes;
	so the bug was introduced since then.  In fact, the bug was introduced
	with this commit:

	  commit a2827364e2bf19910fa5a54364a594a5ba3033b8
	  Date:   Fri Sep 8 15:48:16 2023 +0100

	      gdb: remove final user of the executable_changed observer

	This commit changed how the per-inferior auxv data cache is managed,
	specifically, when the cache is cleared, and it is this that leads to
	the failure.

	This bug is interesting because it exposes a number of issues with
	GDB, I'll explain all of the problems I see, though ultimately, I only
	propose fixing one problem in this commit, which is enough to resolve
	the crash we are currently seeing.

	The crash that we are seeing manifests like this:

	  ...

	  +inferior 1

	So this is problem #1, if we throw an exception while deleting a
	program_space then this is not caught, and is going to crash GDB.

	Problem #2 becomes evident when we ask why GDB is throwing an error in
	this case; the error is thrown because the remote target, operating in
	non-async mode, can't read the auxv data while an inferior is running
	and GDB is waiting for a stop reply.  The problem here then, is why
	does GDB get into a position where it tries to interact with the
	remote target in this way, at this time?  The problem is caused by the
	prune_inferiors call which can be seen in the above backtrace.

	In prune_inferiors we check if the inferior is deletable, and if it
	is, we delete it.  The problem is, I think, we should also check if
	the target is currently in a state that would allow us to delete the
	inferior.  We don't currently have such a check available, we'd need
	to add one, but for the remote target, this would return false if the
	remote is in async mode and the remote is currently waiting for a stop
	reply.  With this change in place GDB would defer deleting the
	inferior until the remote target has stopped, at which point GDB would
	be able to refill the auxv cache successfully.

	And then, problem #3 becomes evident when we ask why GDB is needing to
	refill the auxv cache now when it didn't need to for GDB 13.  This is
	where the second commit mentioned above (a2827364e2bf) comes in.
	Prior to this commit, the auxv cache was cleared by the
	executable_changed observer, while after that commit the auxv cache
	was cleared by the new_objfile observer -- but only when the
	new_objfile observer is used in the special mode that actually means
	that all objfiles have been unloaded (I know, the overloading of the
	new_objfile observer is horrible, and unnecessary, but it's not really
	important for this bug).

	The difference arises because the new_objfile observer is triggered
	from clear_symtab_users, which in turn is called from
	program_space::~program_space.  The new_objfile observer for auxv does
	this:

	  static void
	  auxv_new_objfile_observer (struct objfile *objfile)
	  {
	    if (objfile == nullptr)
	      invalidate_auxv_cache_inf (current_inferior ());
	  }

	That is, when all the objfiles are unloaded, we clear the auxv cache
	for the current inferior.

	The problem is, then when we look at the prune_inferiors ->
	delete_inferior -> ~program_space path, we see that the current
	inferior is not going to be an inferior that exists within the
	program_space being deleted; delete_inferior removes the deleted
	inferior from the global inferior list, and then only deletes the
	program_space if program_space::empty() returns true, which is only
	the case if the current inferior isn't within the program_space to
	delete, and no other inferior exists within that program_space
	either.

	What this means is that when the new_objfile observer is called we
	can't rely on the current inferior having any relationship with the
	program space in which the objfiles were removed.  This was an error
	in the commit a2827364e2bf, the only thing we can rely on is the
	current program space.  As a result of this mistake, after commit
	a2827364e2bf, GDB was sometimes clearing the auxv cache for a random
	inferior.  In the native target case this was harmless as we can
	always refill the cache when needed, but in the remote target case, if
	we need to refill the cache when the remote target is executing, then
	we get the crash we observed.

	And additionally, if we think about this a little more, we see that
	commit a2827364e2bf made another mistake.  When all the objfiles are
	removed, they are removed from a program_space, a program_space might
	contain multiple inferiors, so surely, we should clear the auxv cache
	for all of the matching inferiors?

	Given these two insights, that the current_inferior is not relevant,
	only the current_program_space, and that we should be clearing the
	cache for all inferiors in the current_program_space, we can update
	auxv_new_objfile_observer to:

	  if (objfile == nullptr)
	    {
	      for (inferior *inf : all_inferiors ())
		{
		  if (inf->pspace == current_program_space)
		    invalidate_auxv_cache_inf (inf);
		}
	    }

	With this change we now correctly clear the auxv cache for the correct
	inferiors, and GDB no longer needs to refill the cache at an
	inconvenient time, this avoids the crash we were seeing.

	And finally, we reach problem #4.  Inspired by the observation that
	using the current_inferior from within the ~program_space function was
	not correct, I added some debug to see if current_inferior() was
	called anywhere else (below ~program_space), and the answer is yes,
	it's called a often.  Mostly the culprit is GDB doing:

	  current_inferior ()->top_target ()-> ....

	But I think all of these calls are most likely doing the wrong thing,
	and only work because the top target in all these cases is shared
	between all inferiors, e.g. it's the native target, or the remote
	target for all inferiors.  But if we had a truly multi-connection
	setup, then we might start to see odd behaviour.

	Problem #1 I'm just ignoring for now, I guess at some point we might
	run into this again, and then we'd need to solve this.  But in this
	case I wasn't sure what a "good" solution would look like.  We need
	the auxv data in order to implement the linux_is_uclinux() function.
	If we can't get the auxv data then what should we do, assume yes, or
	assume no?  The right answer would probably be to propagate the error
	back up the stack, but then we reach ~program_space, and throwing
	exceptions from a destructor is problematic, so we'd need to catch and
	deal at this point.  The linux_is_uclinux() call is made from within
	gdbarch_has_shared_address_space(), which is used like:

	  if (!gdbarch_has_shared_address_space (target_gdbarch ()))
	    delete this->aspace;

	So, we would have to choose; delete the address space or not.  If we
	delete it on error, then we might delete an address space that is
	shared within another program space.  If we don't delete the address
	space, then we might leak it.  Neither choice is great.

	A better solution might be to have the address spaces be reference
	counted, then we could remove the gdbarch_has_shared_address_space
	call completely, and just rely on the reference count to auto-delete
	the address space when appropriate.

	The solution for problem #2 I already hinted at above, we should have
	a new target_can_delete_inferiors() call, which should be called from
	prune_inferiors, this would prevent GDB from trying to delete
	inferiors when a (remote) target is in a state where we know it can't
	delete the inferior.  Deleting an inferior often (always?) requires
	sending packets to the remote, and if the remote is waiting for a stop
	reply then this will never work, so the pruning should be deferred in
	this case.

	The solution for problem #3 is included in this commit.

	And, for problem #4, I'm not sure what the right solution is.  Maybe
	delete_inferior should ensure the inferior to be deleted is in place
	when ~program_space is called?  But that seems a little weird, as the
	current inferior would, in theory, still be using the current
	program_space...

	Anyway, after this commit, the gdb.python/py-progspace-events.exp test
	now passes when run with the native-extended-remote board.

	gdb: fix reread_symbols when an objfile has target: prefix
	When using a remote target, it is possible to tell GDB that the
	executable to be debugged is located on the remote machine, like this:

	  (gdb) target extended-remote :54321
	  ... snip ...
	  (gdb) file target:/tmp/hello.x
	  Reading /tmp/hello.x from remote target...
	  warning: File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead.
	  Reading /tmp/hello.x from remote target...
	  Reading symbols from target:/tmp/hello.x...
	  (gdb)

	So far so good.  However, when we try to start the inferior we run
	into a small problem:

	  (gdb) set remote exec-file /tmp/hello.x
	  (gdb) start
	  `target:/tmp/hello.x' has disappeared; keeping its symbols.
	  Temporary breakpoint 1 at 0x401198: file /tmp/hello.c, line 18.
	  Starting program: target:/tmp/hello.x
	  ... snip ...

	  Temporary breakpoint 1, main () at /tmp/hello.c:18
	  18	  printf ("Hello World\n");
	  (gdb)

	Notice this line:

	  `target:/tmp/hello.x' has disappeared; keeping its symbols.

	That's wrong, the executable hasn't been removed, GDB just doesn't
	know how to check if the remote file has changed, and so falls back to
	assuming that the file has been removed.

	In this commit I update reread_symbols to use bfd_stat instead of
	a direct stat call, this adds support for target: files, and fixes the
	problem.

	This change was proposed before in this commit:

	  https://inbox.sourceware.org/gdb-patches/20200114210956.25115-3-tromey@adacore.com/

	However, that patch never got merged, and seemed to get stuck
	discussing issues around gnulib stat vs system stat as used by BFD.

	I didn't 100% understand the issues discussed in that thread, however,
	I think the problem with the previous thread related to the changes in
	gdb_bfd.c, rather than to the change in symfile.c.  As such, I think
	this change might be acceptable, my reasoning is:

	  - the objfile::mtime field is set by a call to bfd_get_mtime (see
	    objfiles.c), which calls bfd_stat under the hood.  This will end
	    up using the system stat,

	  - In symfile.c we currently call stat directly, which will call the
	    gnulib stat, which, if I understand the above thread correctly,
	    might give a different result to the system stat in some cases,

	  - By switching to using bfd_stat in symfile.c we should now be
	    consistently calling the system stat.

	There is another issue that came up during testing that this commit
	fixes.  Consider this GDB session:

	  $ gdb -q
	  (gdb) target extended-remote | ./gdbserver/gdbserver --multi --once -
	  Remote debugging using | ./gdbserver/gdbserver --multi --once -
	  Remote debugging using stdio
	  (gdb) file /tmp/hello.x
	  Reading symbols from /tmp/hello.x...
	  (gdb) set remote exec-file /tmp/hello.x
	  (gdb) start
	  ... snip ...
	  (gdb) load
	  `system-supplied DSO at 0x7ffff7fcf000' has disappeared; keeping its symbols.
	  Loading section .interp, size 0x1c lma 0x4002a8
	  ... snip ...
	  Start address 0x0000000000401050, load size 2004
	  Transfer rate: 326 KB/sec, 87 bytes/write.

	Notice this line:

	  `system-supplied DSO at 0x7ffff7fcf000' has disappeared; keeping its symbols.

	We actually see the same output, for the same reasons, when using a
	native target, like this:

	  $ gdb -q
	  (gdb) file /tmp/hello.x
	  Reading symbols from /tmp/hello.x...
	  (gdb) start
	  ... snip ...
	  (gdb) load
	  `system-supplied DSO at 0x7ffff7fcf000' has disappeared; keeping its symbols.
	  You can't do that when your target is `native'
	  (gdb)

	In both cases this line appears because load_command (symfile.c) calls
	reread_symbols, and reread_symbols loops over every currently loaded
	objfile and tries to check if the file has changed on disk by calling
	stat.

	However, the `system-supplied DSO at 0x7ffff7fcf000' is an in-memory
	BFD, the filename for this BFD is literally the string
	'system-supplied DSO at 0x7ffff7fcf000'.

	Before this commit GDB would try to use the system 'stat' call to stat
	the file `system-supplied DSO at 0x7ffff7fcf000', which obviously
	fails; there's no file with that name (usually).  As a consequence of
	the stat failing GDB prints the ' .... has disappeared ...' line.

	Initially, all this commit did was switch from using 'stat' to using
	'bfd_stat'.  Calling bfd_stat on an in-memory BFD works just fine,
	however, BFD just fills the 'struct stat' buffer with zeros (except
	for the file size), see memory_bstat in bfd/bfdio.c.

	However, there is a bit of a weirdness about in-memory BFDs.  When
	they are initially created the libbfd caches an mtime within the bfd
	object, this is done in bfd_from_remote_memory (elfcode.h), the cached
	mtime is the time at which the in-memory BFD is created.

	What this means is that when GDB creates the in-memory BFD, and we
	call bfd_get_mtime(), the value returned, which GDB caches within
	objfile::mtime is the creation time of the in-memory BFD.  But, when
	this patch changes to use bfd_stat() we now get back 0, and so we
	believe that the in-memory BFD has changed.  This is a change in
	behaviour.

	To avoid this change in behaviour, in this commit, I propose that we
	always skip in-memory BFDs in reread_symbols.  This preserves the
	behaviour from before this commit -- mostly.

	As I'm not specifically checking for, and then skipping, in-memory
	BFDs, we no longer see this line:

	  `system-supplied DSO at 0x7ffff7fcf000' has disappeared; keeping its symbols.

	Which I think is an improvement.

	gdb: remove print_sys_errmsg
	This started with me running into this comment in symfile.c:

	  /* FIXME, should use print_sys_errmsg but it's not filtered.  */
	  gdb_printf (_("`%ps' has disappeared; keeping its symbols.\n"),
	              styled_string (file_name_style.style (), filename));

	In this particular case I think I disagree with the comment; I think
	the output should be a warning rather than just a message printed to
	gdb_stdout, I think when the executable, or some other objfile that is
	currently being debugged, disappears from disk, this is likely an
	unexpected situation, and worth warning the user about.

	So, in theory, I could just call print_sys_errmsg and remove the
	comment, but that would mean loosing the filename styling in the
	output... so in the end I remove the comment and updated the code to
	call warning.

	But that got me looking at print_sys_errmsg and how it's used.

	Currently the function takes a string and an errno, and prints, to
	stderr, the string followed by the result of calling strerror on the
	errno.

	In some places the string passed to print_sys_errmsg is just a
	filename, and this is used when something goes wrong.  In these cases,
	I think calling warning rather than gdb_printf to gdb_stderr, would be
	better, and in fact, in a couple of places we manually print a
	"warning" prefix, and then call print_sys_errmsg.  And so, for these
	users I have added a new function warning_filename_and_errno, which
	takes a filename, which is printed with styling, and an errno, which
	is passed through strerror and the resulting string printed.  This new
	function calls warning to print its output.  I then updated some of
	the print_sys_errmsg users to use this new function.

	Some other users of print_sys_errmsg are also emitting what is clearly
	a warning, however, the string being passed in is more than just a
	filename, so the new warning_filename_and_errno function can't be
	used, it would style the whole string.  For these users I have
	switched to calling warning directly, this allows me to style the
	warning message correctly.

	Finally, in inflow.c there is one last call to print_sys_errmsg, in
	this case I just inlined the definition of print_sys_errmsg.  This is
	a really weird case, as after printing this message GDB just does a
	hard exit.  This is pretty old code, dating back to the initial GDB
	import, I guess it should be updated to call error() maybe, but I'm
	reluctant to make this change as part of this commit, just in case
	there's some reason why we can't throw an error at this point.

	With that done there are now no users of print_sys_errmsg, and so the
	old function can be removed.

	While I was doing all of the above I added some additional filename
	styling in soure.c, this is in an else block where the if contained
	the print_sys_errmsg call, so these felt related.

	And finally, while I was updating the uses of print_sys_errmsg in
	procfs.c, I noticed that we used a static errmsg buffer to format some
	error strings.  As the above changes got rid of one of the users of
	errmsg I also removed the other two users, and the static buffer.

	There were a couple of tests that depended on the existing output
	message format that needed updating.  In one case we gained an extra
	'warning: ' prefix, and in the other 'Warning: ' becomes 'warning: ',
	I think in both cases the new output is an improvement.

	gdb: remove use of a static buffer for building error strings
	I noticed in procfs.c that we use a static buffer for building error
	strings when we could easily use std::string and string_printf to
	achieve the same result, this commit does that.

	I ran into this while performing a further refactor/cleanup that will
	be presented in a later patch in this series, and thought this was
	worth splitting out into its own patch.

	As far as I can tell, only Solaris uses procfs.c, so I did a test
	build on a Solaris machine, and I don't believe that I've broken
	anything.

	There should be no user visible changes after this commit.

	gdb: use archive name in warning when appropriate
	While working on some other patch I noticed that in reread_symbols
	there is a diagnostic message that can be printed, and in some cases
	we might use the wrong filename in the message.

	The code in question is checking to see if an objfile has changed on
	disk, we do this by stat-ing the on disk file and checking the mtime.
	If this file has been removed from disk then we print a message that
	the file has been removed, however, if the objfile is within an
	archive then we stat the archive itself, but then warn that the
	component within the archive has disappeared.  I think it makes more
	sense to say that the archive has disappeared.

	The last related commit is this one:

	  commit 02aeec7bde8ec8a04d14a5637e75f1c6ab899e23
	  Date:   Tue Apr 27 21:01:30 2010 +0000

	      Check library name rather than member name when rereading symbols.

	Though this just makes the code to stat the archive unconditional, the
	code in question existed before this commit.

	However, the above commit doesn't include any tests, and seems to
	indicate that the problem being addressed was seen on Darwin.  I'm not
	sure how to setup a test where GDB is using an objfile from within an
	archive, and so there's no tests for this commit...

	... but if someone can let me know how I can setup a suitable test,
	please let me know and I'll try to get something working.

	sme: Add SVE/SME testcases
	Add 5 SVE/SME tests to exercise all the new features like reading/writing
	registers, pseudo-registers, signal frames and core files.

	- Sanity check for SME: Gives a brief smoke test to make sure the most basic
	of features are working correctly.

	- ZA unavailability tests: Validates the behavior/content of the ZA register
	is correct when no payload is available.  It also exercises changing the
	vector lengths.

	- ZA availability tests: These tests exercise reading/writing to all the
	possible ZA pseudo-registers, and validates the state is correct.

	- Core file tests: Validates that core file reading and writing works
	correctly and that all state dumped/loaded is sane.  This is exercised for
	both Linux Kernel core files and gcore core files.

	- Signal frame tests: Validates the correct restoration of SME/SVE/FPSIMD
	values across signal frames.

	Since some of these tests are very lengthy and take a little while to run
	(under QEMU at the moment), I decided to parallelize them into smaller
	chunks so we can throw some more CPU power at them so they run faster.

	I'd still like to add a few more tests to give the testsuite more coverage
	in the areas of SME/SVE.  Hopefully in the near future that will happen.

	Just a reminder that these SME tests are currently unsupported when gdb is
	connected to a remote target.  That's because the RSP doesn't support
	communicating changes in vector lenghts mid-execution, so gdb will always
	get wrong state from the remote target.

	corefile/bug: Add hook to control the use of target description notes from corefiles
	Due to the nature of the AArch64 SVE/SME extensions in GDB, each thread
	can potentially have distinct target descriptions/gdbarches.

	When loading a gcore-generated core file, at the moment GDB gives priority
	to the target description dumped to NT_GDB_TDESC.  Though technically correct
	for most targets, it doesn't work correctly for AArch64 with SVE or SME
	support.

	The correct approach for AArch64/Linux is to either have per-thread target
	description notes in the corefiles or to rely on the
	gdbarch_core_read_description hook, so it can figure out the proper target
	description for a given thread based on the various available register notes.

	The former, although more correct, doesn't address the case of existing gdb's
	that only output a single target description note.

	This patch goes for the latter, and adds a new gdbarch hook to conditionalize
	the use of the corefile target description note. The hook is called
	use_target_description_from_corefile_notes.

	The hook defaults to returning true, meaning targets will use the corefile
	target description note.  AArch64 Linux overrides the hook to return false
	when it detects any of the SVE or SME register notes in the corefile.

	Otherwise it should be fine for AArch64 Linux to use the corefile target
	description note.

	When we support per-thread target description notes, then we can augment
	the AArch64 Linux hook to rely on those notes.

	corefile/bug: Use thread-specific gdbarch when dumping register state to core files
	When we have a core file generated by gdb (via the gcore command), gdb dumps
	the target description to a note.  During loading of that core file, gdb will
	first try to load that saved target description.

	This works fine for almost all architectures. But AArch64 has a few
	dynamically-generated target descriptions/gdbarch depending on the vector
	length that was in use at the time the core file was generated.

	The target description gdb dumps to the core file note is the one generated
	at the time of attachment/startup.  If, for example, the SVE vector length
	changed during execution, this would not reflect on the core file, as gdb
	would still dump the initial target description.

	Another issue is that the gdbarch potentially doesn't match the thread's
	real gdbarch, and so things like the register cache may have different formats
	and sizes.

	To address this, fetch the thread's architecture before dumping its register
	state.  That way we will always use the correct target description/gdbarch.

	sme: Fixup sigframe gdbarch when vg/svg changes
	With SME, where you have two different vector lengths (vl and svl), it may be
	the case that the current frame has a set of vector lengths (A) but the signal
	context has a distinct set of vector lengths (B).

	In this case, we may run into a situation where GDB attempts to use a gdbarch
	created for set A, but it is really dealing with a frame that was using set
	B.

	This is problematic, specially with SME, because now we have a different
	number of pseudo-registers and types that gets cached on creation of each
	gdbarch variation.

	For AArch64 we really need to be able to use the correct gdbarch for each
	frame, and I noticed the signal frame (tramp-frame) doesn't have a settable
	prev_arch field.  So it ends up using the default frame_unwind_arch function
	and eventually calling get_frame_arch (next_frame).  That means the previous
	frame will always have the same gdbarch as the current frame.

	This patch first refactors the AArch64/Linux signal context code, simplifying
	it and making it reusable for our purposes of calculating the previous frame's
	gdbarch.

	I introduced a struct that holds information that we have found in the signal
	context, and with which we can make various decisions.

	Finally, a small change to tramp-frame.c and tramp-frame.h to expose a
	prev_arch hook that the architecture can set.

	With this new field, AArch64/Linux can implement a hook that looks at the
	signal context and infers the gdbarch for the previous frame.

	sme: Add support for SME
	Enable SME support in gdbserver by adjusting the usual fields.  There is
	not much to this patch because the code is either in gdb or it is shared
	between gdbserver and gdb.  One exception is the bump to gdbserver's
	PBUFSIZ from 18432 to 131104.

	Since the ZA register can be quite big (256 * 256 bytes), the g/G remote
	packet will also become quite big

	From gdbserver/tdesc.cc:init_target_desc, I estimated the new size should
	be at least (2 * 256 * 256 + 32), which yields 131104.

	It is also unlikely we will find a process starting up with SVL set to 256.

	Ideally we'd adjust the packet size dynamically based on what we need, but
	for now this should do.

	Please note we have the same limitation for SME that we have for SVE, and
	that is the fact gdbserver cannot communicate vector length changes to gdb
	via the remote protocol.

	sme: Enable SME registers and pseudo-registers
	The SME (Scalable Matrix Extension) [1] exposes a new matrix register ZA with
	variable sizes.  It also exposes a new mode called streaming mode.

	Similarly to SVE, the ZA register size is dictated by a vector length, but the
	SME vector length is called streaming vetor length. The total size for
	ZA in a given moment is svl x svl.

	In streaming mode, the SVE registers have their sizes based on svl rather than
	the regular vector length (vl).

	The feature detection is controlled by the HWCAP2_SME bit, but actual support
	should be validated by attempting a ptrace call for one of the new register
	sets: NT_ARM_ZA and NT_ARM_SSVE.

	Due to its large size, the ZA register is exposed as a vector of bytes, but we
	introduce a number of pseudo-registers that gives various different views
	into the ZA contents. These can be arranged in a couple categories: tiles and
	tile slices.

	Tiles are matrices the same size or smaller than ZA.  Tile slices are vectors
	which map to ZA's rows/columns in different ways.

	A new dynamic target description is provided containing the ZA register, the SVG
	register and the SVCR register.  The size of ZA, like the SVE vector registers,
	is based on the vector length register SVG (VG for SVE).

	This patch enables SME register support for gdb.

	sve: Fix return command when using V registers in a SVE-enabled target
	In a target without SVE support, the V registers have a size of 16 bytes,
	otherwise they may have a size bigger than 16 bytes (depending on the current
	vector length for the Z registers, as they overlap the V registers).

	In aarch64-tdep.c:aarch64_store_return_value, the code is laid
	out in a way that allocates the buffer with the size of the register, but
	only updates the amount of bytes for the particular type we're returning.

	This may cause a situation where we have a register size of 32 bytes but
	are returning a floating point value of 8 bytes.  The temporary buffer
	will therefore have 32 bytes, but we'll only update 8 bytes of it.

	When we write the entire register back, it will have potentially 24 bytes
	of garbage in it.

	Fix this by first reading the original contents of the register and then
	overriding only the bytes that we need for the return value.

	refactor: Simplify SVE interface to read/write registers
	This is a patch in preparation to upcoming patches enabling SME support.  It
	attempts to simplify the gdb/gdbserver shared interface used to read/write
	SVE registers.

	Where the current code makes use of unique_ptr, allocating a new buffer by
	hand and passing a buffer around, this patch makes that code use
	gdb::byte_vector and passes a reference to this byte vector to the functions,
	allowing the functions to have ready access to the size of the buffer.

	It also shares a bit more code between gdb and gdbserver, in particular around
	handling of ptrace get/set requests for SVE.

	I think gdbserver could be refactored to handle register reads/writes more
	like gdb's native layer as opposed to letting the generic linux-low layer do
	the ptrace calls.  This is not very flexible and assumes one size for the
	responses.  If you have something like NT_ARM_SVE, where you can have either
	FPSIMD or SVE contents, it doesn't work that well.

	I didn't want to change that interface right now as it is a bit too much work
	and touches all the targets, some of which I can't easily test.

	Hence the reason why the buffer the generic linux-now passes down to
	linux-aarch64-low is unused or ignored.

	No user-visible changes should happen as part of this refactor other than a
	slightly reworded warning message.

	While doing the refactor, I also noticed what seems to be a mistake in checking
	if the register cache contains active (non-zero) SVE data.

	For instance, the original code did something like this in
	aarch64_sve_regs_copy_from_reg_buf:

	has_sve_state |= reg_buf->raw_compare (AARCH64_SVE_Z0_REGNUM + i
					       reg, sizeof (__int128_t));

	"reg" is a zeroed-out buffer that we compare the Z register contents
	past the first 128 bits.  The problem here is that raw_compare returns
	1 if the contents compare the same, which means has_sve_state will be
	true.  But if we compared the Z register contents to 0, it means we
	*do not* have SVE state, and therefore has_sve_state should be false.

	The consequence of this mistake is that we convert the initial
	FPSIMD-formatted data we get from ptrace for the NT_ARM_SVE register
	set to a SVE-formatted one.

	In the end, this doesn't cause user-visible differences because the
	values of both the Z and V registers will still be the same.  But the
	logic is not correct.

	I used the opportunity to fix this, and it gets tested later on by
	the additional SME tests.

	I do plan on submitting some SVE-specific tests to make sure we have
	a bit more coverage in GDB's testsuite.

	aarch64: system register aliasing detection
	This patch adds a mechanism for system register name alias detection
	to register-matching mechanisms.

	A new `F_REG_ALIAS' flag is added to the set of register flags and
	used to label which entries in aarch64_sys_regs[] correspond to
	aliases (and thus which CPENC values are non-unique in this array).

	Where this is used is, for example, in `aarch64_print_operand' where,
	in the case of system register decoding, the aarch64_sys_regs[] array
	is iterated through until a match in CPENC value is made and the first
	match accepted.  If insufficient care is given in the ordering of
	system registers in this array, the alias is encountered before the
	"real" register and used incorrectly as the register name in the
	disassembled output.

	With this flag and the new `aarch64_sys_reg_alias_p' test, search
	candidates corresponding to aliases can be conveniently skipped over.

	One concrete example of where this is useful is with the
	`trcextinselr0' system register.  It was initially placed in the
	system register list before `trcextinselr', in contrast to a more
	natural alphabetical order.

	gdb/corefile: write NT_GDB_TDESC based on signalled thread
	When creating a core file from within GDB we include a NT_GDB_TDESC
	that includes the target description of the architecture in use.

	For architectures with dynamic architectures (e.g. AArch64 with
	sve/sme) the original architecture, calculated from the original
	target description, might not match the per-thread architecture.

	In the general case, where each thread has a different architecture,
	then we really need a separate NT_GDB_TDESC for each thread, however,
	there's currently no way to read in multiple NT_GDB_TDESC.

	This commit is a step towards per-thread NT_GDB_TDESC.  In this commit
	I have updated the function that writes the NT_GDB_TDESC to accept a
	gdbarch (rather than calling target_gdbarch() to find a gdbarch), and
	I now pass in the gdbarch of the signalled thread.

	In many cases (though NOT all) targets with dynamic architectures
	really only use a single architecture, even when there are multiple
	threads, so in the common case, this should ensure that GDB emits an
	architecture that is more likely to be correct.

	Additional work will be needed in order to support corefiles with
	truly per-thread architectures, but that will need to be done in the
	future.

	gdb: add Python events for program space addition and removal
	Initially I just wanted a Python event for when GDB removes a program
	space, I'm writing a Python extension that caches information for each
	program space, and need to know when I should discard entries for a
	particular program space.

	But, it seemed easy enough to also add an event for when GDB adds a
	new program space, so I went ahead and added both new events.

	Of course, we don't currently have an observable for program space
	addition or removal, so I first needed to add these.  After that it's
	pretty simple to add two new Python events and have these trigger.

	The two new event registries are:

	  events.new_progspace
	  events.free_progspace

	These emit NewProgspaceEvent and FreeProgspaceEvent objects
	respectively, each of these new event types has a 'progspace'
	attribute that contains the relevant gdb.Progspace object.

	There's a couple of things to be mindful of.

	First, it is not possible to catch the NewProgspaceEvent for the very
	first program space, the one that is created when GDB first starts, as
	this program space is created before any Python scripts are sourced.

	In order to allow this event to be caught we would need to defer
	creating the first program space, and as a consequence the first
	inferior, until some later time.  But, existing scripts could easily
	depend on there being an initial inferior, so I really don't think we
	should change that -- and so, we end up with the consequence that we
	can't catch the event for the first program space.

	The second, I think minor, issue, is that GDB doesn't clean up its
	program spaces upon exit -- or at least, they are not cleaned up
	before Python is shut down.  As a result, any program spaces in use at
	the time GDB exits don't generate a FreeProgspaceEvent.  I'm not
	particularly worried about this for my use case, I'm using the event
	to ensure that a cache doesn't hold stale entries within a single GDB
	session.  It's also easy enough to add a Python at-exit callback which
	can do any final cleanup if needed.

	Finally, when testing, I did hit a slightly weird issue with some of
	the remote boards (e.g. remote-stdio-gdbserver).  As a consequence of
	this issue I see some output like this in the gdb.log:

	  (gdb) PASS: gdb.python/py-progspace-events.exp: inferior 1
	  step
	  FreeProgspaceEvent: <gdb.Progspace object at 0x7fb7e1d19c10>
	  warning: cannot close "target:/lib64/libm.so.6": Cannot execute this command while the target is running.
	  Use the "interrupt" command to stop the target
	  and then try again.
	  warning: cannot close "target:/lib64/libc.so.6": Cannot execute this command while the target is running.
	  Use the "interrupt" command to stop the target
	  and then try again.
	  warning: cannot close "target:/lib64/ld-linux-x86-64.so.2": Cannot execute this command while the target is running.
	  Use the "interrupt" command to stop the target
	  and then try again.
	  do_parent_stuff () at py-progspace-events.c:41
	  41        ++global_var;
	  (gdb) PASS: gdb.python/py-progspace-events.exp: step

	The 'FreeProgspaceEvent ...' line is expected, that's my test Python
	extension logging the event.  What isn't expected are all the blocks
	like:

	  warning: cannot close "target:/lib64/libm.so.6": Cannot execute this command while the target is running.
	  Use the "interrupt" command to stop the target
	  and then try again.

	It turns out that this has nothing to do with my changes, this is just
	a consequence of reading files over the remote protocol.  The test
	forks a child process which GDB stays attached too.  When the child
	exits, GDB cleans up by calling prune_inferiors, which in turn can
	result in GDB trying to close some files that are open because of the
	inferior being deleted.

	If the prune_inferiors call occurs when the remote target is
	running (and in non-async mode) then GDB will try to send a fileio
	packet while the remote target is waiting for a stop reply, and the
	remote target will throw an error, see remote_target::putpkt_binary in
	remote.c for details.

	I'm going to look at fixing this, but, as I said, this is nothing to
	do with this change, I just mention it because I ended up needing to
	account for these warning messages in one of my tests, and it all
	looks a bit weird.

	gdb/testsuite: Add relative versus absolute LD_LIBRARY_PATH test
	At one time, circa 2006, there was a bug, which was presumably fixed
	without adding a test case:

	    If you provided some relative path to the shared library, such as
	    with

		export LD_LIBRARY_PATH=.

	    then gdb would fail to match the shared library name during the
	    TLS lookup.

	I think there may have been a bit more to it than is provided by that
	explanation, since the test also takes care to split the debug info
	into a separate file.

	In any case, this commit is based on one of Red Hat's really old
	local patches.  I've attempted to update it and remove a fair amount
	of cruft, hopefully without losing any critical elements from the
	test.

	Testing on Fedora 38 (correctly) shows 1 unsupported test for
	native-gdbserver and 5 PASSes for the native target as well as
	native-extended-gdbserver.

	In his review of v1 of this patch, Lancelot SIX observed that
	'thread_local' could be used in place of '__thread' in the C source
	files.  But it only became available via the standard in C11, so I
	used additional_flags=-std=c11 for compiling both the shared object
	and the main program.

	Also, while testing with CC_FOR_TARGET=clang, I found that
	'additional_flags=-Wl,-soname=${binsharedbase}' caused clang
	to complain that this linker flag was unused when compiling
	the source file, so I moved this linker option to 'ldflags='.

	My testing for this v2 patch shows the same results as with v1,
	but I've done additional testing with CC_FOR_TARGET=clang as
	well.  The results are the same as when gcc is used.

	due to asm_lines being empty after the call to tui_disassemble, while
	asm_lines.back () assumes that it's not empty.

	I have not been able to reproduce that segfault in that original setting, I'm
	not sure of the exact scenario (though looking back it probably involved
	"set detach-on-fork off").

	What likely happened is that I managed to reproduce PR29040, and TUI (attempted
	to) display the disassembly for address 0, which led to the gdb segfault.

	When gdb_print_insn encounters an insn it cannot print because it can't read
	the memory, it throws a MEMORY_ERROR that is caught by tui_disassemble.

	The specific bit that causes the gdb segfault is that if gdb_print_insn throws
	a MEMORY_ERROR for the first insn in tui_disassemble, it returns an empty
	asm_lines.

	FWIW, I did manage to reproduce the gdb segfault as follows:
	...
	$ gdb -q \
	    -iex "set pagination off" \
	    /usr/bin/rustc \
	    -ex "set breakpoint pending on" \
	    -ex "b dl_main" \
	    -ex run \
	    -ex "up 4" \
	    -ex "layout asm" \
	    -ex "print \$pc"
	  ...
	<TUI>
	  ...
	$1 = (void (*)()) 0x1
	(gdb)
	...
	Now press <up>, and the segfault triggers.

	Fix the segfault by handling asm_lines.empty () results of tui_disassemble in
	tui_find_disassembly_address.

	I've written a unit test that exercises this scenario.

	Tested on x86_64-linux.

	gdb: use reopen_exec_file from reread_symbols
	This commit fixes an issue that was discovered while writing the tests

	I noticed that, when GDB restarts an inferior, the executable_changed

	from:

	While the second originates from:

	  #0  exec_file_attach (filename=0x3d7a1d0 "/tmp/hello.x", from_tty=0) at ../../src/gdb/exec.c:513
	  #1  0x0000000000dfe525 in reread_symbols (from_tty=1) at ../../src/gdb/symfile.c:2517

	In the first case the call to exec_file_attach first passes through
	reopen_exec_file.  The reopen_exec_file performs a modification time
	check on the executable file, and only calls exec_file_attach if the
	executable has changed on disk since it was last loaded.

	However, in the second case things work a little differently.  In this
	case GDB is really trying to reread the debug symbol.  As such, we
	iterate over the objfiles list, and for each of those we check the
	modification time, if the file on disk has changed then we reload the
	debug symbols from that file.

	However, there is an additional check, if the objfile has the same
	name as the executable then we will call exec_file_attach, but we do
	so without checking the cached modification time that indicates when
	the executable was last reloaded, as a result, we reload the
	executable twice.

	In this commit I propose that reread_symbols be changed to
	unconditionally call reopen_exec_file before performing the objfile
	iteration.  This will ensure that, if the executable has changed, then
	the executable will be reloaded, however, if the executable has
	already been recently reloaded, we will not reload it for a second
	time.

	After handling the executable, GDB can then iterate over the objfiles
	list and reload them in the normal way.

	With this done I now see the executable reloaded only once when GDB
	restarts an inferior, which means I can remove the kfail that I added
	to the gdb.python/py-exec-file.exp test in the previous commit.

	gdb/python: make the executable_changed event available from Python
	This commit makes the executable_changed observable available through
	the Python API as an event.  There's nothing particularly interesting
	going on here, it just follows the same pattern as many of the other
	Python events we support.

	The new event registry is called events.executable_changed, and this
	emits an ExecutableChangedEvent object which has two attributes, a
	gdb.Progspace called 'progspace', this is the program space in which
	the executable changed, and a Boolean called 'reload', which is True
	if the same executable changed on disk and has been reloaded, or is
	False when a new executable has been loaded.

	One interesting thing did come up during testing though, you'll notice
	the test contains a setup_kfail call.  During testing I observed that
	the executable_changed event would trigger twice when GDB restarted an
	inferior.  However, the ExecutableChangedEvent object is identical for
	both calls, so the wrong information is never sent out, we just see
	one too many events.

	I tracked this down to how the reload_symbols function (symfile.c)
	takes care to also reload the executable, however, I've split fixing
	this into a separate commit, so see the next commit for details.

	gdb: pass more arguments to the executable_changed observer
	This commit continues the work of the previous few commits.

	My goal is to expose the executable_changed observer through the
	Python API as an event.

	At this point adding executable_changed as an event to the Python API
	is trivial, but before I do that I would like to add some additional
	arguments to the observable, which currently has no arguments at all.

	The new arguments I wish to add are:

	 1. The program_space in which the executable was changed, and

	 2. A boolean flag that will indicate if the executable changed to a
	 whole new path, or if GDB just spotted that the executable changed on
	 disk (e.g. the user recompiled the executable).

	In this commit I change the signature of the observable and then pass
	the arguments through at the one place where this observable is
	notified.

	As there are (currently) no users of this observable nothing else
	needs updating.  In the next commit I'll add a listener for this
	observable in the Python code, and expose this as an event in the
	Python API.

	Additionally, with this change, it should be possible to update the
	insight debugger to make use of this observable rather than using the
	deprecated_exec_file_display_hook (as it currently does), which will
	then allow this hook to be removed from GDB.

	There should be no user visible changes after this commit.

	gdb: remove unnecessary notification of executable_changed observer
	This commit continues the work of the previous two commits.

	My goal, in the next couple of commits, is to expose the
	executable_changed observable in the Python API as an event.  However,
	before I do that I want to remove the use of the executable_changed
	observable from the reread_symbols function in symfile.c as this use
	isn't directly associated with a change of the executable file, and so
	seems wrong.

	In the previous two commits I have removed all users of the
	executable_changed observer as I believe those users can, and should,
	actually be listening for the new_objfile observable instead, so now
	there are no users of the executable_changed observable.

	As such, I think removing the use of executable_changed from the
	function reread_symbols is perfectly safe, and correct.  At this point
	the executable has not been changed, so we shouldn't be sending an
	executable_changed notification, and, as there is nobody listening to
	this observable, we can't break anything by removing this call.

	There should be no user visible changes after this commit.

	gdb: remove final user of the executable_changed observer
	This commit continues with the task started in the previous commit,
	and is similar in many ways.

	The goal of the next couple of commits is to expose the
	executable_changed observable in the Python API as an event.  Before I
	do this I would like to remove the additional call to the
	executable_changed observable which can be found in the reread_symbols
	function in the symfile.c file, as I don't believe that this use
	actually corresponds to a change in the current executable.

	The previous commit removed one user of the executable_changed
	observable and replaced it with a new_obfile observer instead, and
	this commit does the same thing.

	In auxv.c we use the executable_changed observable to call
	invalidate_auxv_cache, which then calls:

	  invalidate_auxv_cache_inf (current_inferior ());

	The auxv cache is already (additionally) cleared when an inferior
	exits and when an inferior appears.

	As with the previous commit, I think we can safely replace the use of
	the executable_changed observable with a use of the new_obfile
	observable.  All the tests still pass, and with some locally placed
	printf calls, I think that the cache is still being cleared in all the
	cases that should matter.

	gdb: remove one user of the executable changed observer
	My goal for the next few commits is to expose the executable_changed
	observable from the Python API.

	However, there is call to the executable_changed observable in the
	reread_symbols function (in symfile.c), and this doesn't actually
	correspond to the executable changing.  My idea then, is to remove
	this use of the executable_changed observable, but, before I can do
	that, I need to check that nothing is going to break, and that
	requires my to think about the current users of this observable.

	One current user of executable_changed is in symtab.c.  We add an
	executable_changed observer that calls:

	  set_main_name (nullptr, language_unknown);

	to discard all information about the main function when the executable
	changes.

	However, changing the executable doesn't actually change the debug
	information.  The debug information changes when the symbol-file
	changes, so I think this observer is in slightly the wrong place.

	The new_objfile observable is (unfortunately) overloaded, it is called
	when a new objfile is loaded, and also (when its argument is nullptr),
	when all debug information should be discarded.

	It turns out that there is already a new_objfile observer in
	symtab.c.  I propose that, when the argument is nullptr (indicating
	all debug info should be discarded), that we should call set_main_name
	to discard the information about the main function.  We can then
	remove the executable_changed observer from symtab.c.

	All tests still pass, and, in my local world, I added some debug
	printf calls, and I think we are still discarded the main information
	everywhere we need to.

	gdb/x86: use size of XSAVE area of enabled features
	Since commit b42405a1594 ("gdb: Update x86 Linux architectures to
	support XSAVE layouts."), the test gdb.base/gcore.exp fails on my AMD
	Ryzen 3700X machine:

	    FAIL: gdb.base/gcore.exp: corefile restored all registers

	The test gets the register state (saves the output of "info
	all-registers"), saves a core with the "gcore" command, loads the core,
	and checks the register state against the one previously saved.  The
	problem is that when reading registers from the core file, the last half
	of ymm registers is unavailable:

	    (gdb) print $ymm0.v32_int8
	    $1 = {0, -77, -23, -9, -1, 127, 0, 0, 0, -77, -23, -9, -1, 127, 0, 0, <unavailable> <repeats 16 times>}

	One strange thing with this machine is that the bitset of state
	components supported by XCR0 is 0x207, meaning "x87 | SSE | AVX | PKRU",
	but XCR0 at runtime is 0x7, meaning "x87 | SSE | AVX".  So, PKRU appears
	to be supported by the processor, but disabled by the kernel.  I didn't
	find why yet.

	From CPUID leaf EAX=0Dh, ECX=00h, GDB can get:

	 - from EBX: max size of the XSAVE area required by features currently
	   enabled in XCR0.  On my machine, it's 0x340 (832).
	 - from ECX: max size of the XSAVE area required by all features
	   supported by XCR0.  On my machine, it's 0x380 (896).

	At runtime, GDB uses ECX (max size required by all supported features)
	to fill the x86_xsave_layout::sizeof_xsave.  So, when writing the core
	file note for the XSAVE state, it writes a note of size 896, even though
	it doesn't write the PKRU state.  When loading back the core, GDB tries
	to figure out the layout of the XSAVE area based on what features are
	enabled in XCR0 and the size of the note (the size of the XSAVE area).
	Since my combination of XCR0 and size of XSAVE area doesn't match any
	combination known by GDB, GDB falls back to a gdbarch supporting only
	x87 and SSE.

	This patch changes GDB to populate the x86_xsave_layout::sizeof_xsave
	field (and consequently the size of the XSAVE state note in core files)
	using EBX, the size of the XSAVE area required by currently enabled
	features in XCR0.  This makes i387_guess_xsave_layout recognize my case
	with this condition:

	  else if (HAS_AVX (xcr0) && xsave_size == 832)
	    {
	      /* Intel and AMD CPUs supporting AVX.  */
	      layout.avx_offset = 576;
	    }

	In other words, just as if my machine didn't support PKRU at all.

	Another reason why I think this change makes sense is that XSAVE state
	notes in kernel-generated cores on this machine have size 832.  So this
	change makes GDB-generated cores more similar to kernel-generated ones,
	reducing the diversity of XSAVE state notes that GDB needs to be able to
	figure out.

	Note that if PKRU was enabled on my machine, then the effective XSAVE
	area size would be 896 bytes.  We would need to add a case in
	i387_guess_xsave_layout for that combination, since there is no
	currently.  But I don't have a way to test that right now, since I don't
	know why PKRU is disabled.

	Relevant review note from John Baldwin:

	  One further note is that the Linux x86 arches use x86_xsave_length()
	  to infer ("guess") the size of the XSAVE register set that the Linux
	  kernel writes out in core dumps.  On FreeBSD x86 arches, GDB is able
	  to query this size directly from the kernel via ptrace.  My use of ECX
	  for this guess earlier was just not the best guess.  In the case that
	  the kernel enables all of the available features, then ECX and EBX
	  have the same values, so this only matters for a system where the
	  kernel has enabled a subset of available XSAVE extensions.

	x86: drop cpu_arch_tune_flags
	Apparently from its introduction the variable was only ever written (the
	only read is merely to determine whether to write it with another value).
	(Since, due to the need to re-indent, the adjacent lines setting
	cpu_arch_tune need touching anyway, switch to using PREOCESSOR_*
	constants where applicable, to make more obvious what the resulting
	state is going to be.)

	Adjust gdb.thread/pthreads.exp for Cygwin
	The Cygwin runtime spawns a few extra threads, so using hardcoded
	thread numbers in tests rarely works correctly.  Thankfully, this
	testcase already records the ids of the important threads in globals.
	It just so happens that they are not used in a few tests.  This commit
	fixes that.

	With this, the test passes cleanly on Cygwin [1].  Still passes cleanly on
	x86-64 GNU/Linux.

	[1] - with system GDB.  Upstream GDB is missing a couple patches
	Cygwin carries downstream.

	x86: fold certain VEX and EVEX templates
	In anticipation of APX introduce logic to reduce the number of templates
	we have now, allowing to limit some the number of ones we then need to
	gain.

	The fundamental requirements are that
	- attributes be compatible, which specifically means VexW needs to be
	  the same in the templates (which often isn't the case, for VEX
	  encodings having far more WIG tha, EVEX ones),
	- the EVEX form being AVX512F (with or without AVX512VL), not any of its
	  extensions (the same will then be required for APX - it'll need to be
	  APX_F).

	Note that in check_register() there's now a redundant zmm check. Since
	this logic will need revisiting for APX anyway, I'd like to keep it that
	way for now. (Similarly a couple of if()-s which could be folded are
	kept separate, to reduce code churn when adding APX support.)

	gdb/testsuite: add xfail for gdb/29965 in gdb.threads/process-exit-status-is-leader-exit-status.exp
	Bug 29965 shows on a Linux kernel >= 6.1, that test fails consistently
	with:

	    FAIL: gdb.threads/process-exit-status-is-leader-exit-status.exp: iteration=0: continue (the program exited)
	    ...
	    FAIL: gdb.threads/process-exit-status-is-leader-exit-status.exp: iteration=9: continue (the program exited)

	This is due to a change in Linux kernel behavior [1] that affects
	exactly what this test tests.  That is, if multiple threads (including
	the leader) call SYS_exit, the exit status of the process should be the
	exit status of the leader.  After that change in the kernel, it is no
	longer the case.

	Add an xfail in the test, based on the Linux kernel version.  The goal
	is that if a regression is introduced in GDB regarding this feature, it
	should be caught if running on an older kernel where the behavior was
	consistent.

	aarch64: Allow feature flags to occupy >64 bits
	Following on from the previous patch to make the feature macros take
	a word number, this one increases the number of flag words from 1 to 2.

	The patch uses some dummy features to push the number of features
	over 64.  The intention is that these should be reused by real
	features rather than kept as-is.

2023-09-26  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Restructure feature flag handling
	The AArch64 feature-flag code is currently limited to a maximum
	of 64 features.  This patch reworks it so that the limit can be
	increased more easily.  The basic idea is:

	(1) Turn the ARM_FEATURE_FOO macros into an enum, with the enum
	    counting bit positions.

	(2) Make the feature-list macros take an array index argument
	    (currently always 0).  The macros then return the
	    aarch64_feature_set contents for that array index.

	    An N-element array would then be initialised as:

	      { MACRO (0), ..., MACRO (N - 1) }

	(3) Provide convenience macros for initialising an
	    aarch64_feature_set for:

	    - a single feature
	    - a list of individual features
	    - an architecture version
	    - an architecture version + a list of additional features

	(2) and (3) use the preprocessor to generate static initialisers.
	The main restriction was that uses of the same preprocessor macro
	cannot be nested.  So if a macro wants to do something for N individual
	arguments, it needs to use a chain of N macros to do it.  There then
	needs to be a way of deriving N, as a preprocessor token suitable for
	pasting.

	The easiest way of doing that was to precede each list of features
	by the number of features in the list.  So an aarch64_feature_set
	initialiser for three features A, B and C would be written:

	  AARCH64_FEATURES (3, A, B, C)

	This scheme makes it difficult to keep AARCH64_FEATURE_CRYPTO as a
	synonym for SHA2+AES, so the patch expands the former to the latter.

	arc: Update ARC's Gnu Assembler backend with ARCv3 ISA.
	The new Synopsys ARCv3 ISA has a similar instruction format like
	the old ARCv1 and ARCv2 ISA.  Thus, the ARCv3 addition is using
	whatever we have for old ARC processors plus some ARCv3 spcific mods.

	To distinguish between various ARC variants, we introduced two new
	configure defines named TARGET_ARCv3_32 and TARGET_ARCv3_64 which are
	set when we choose either an ARC32 (ARCv3/32) ISA toolchain or an
	ARC64 (ARCv3/64) ISA toolchain.

	gdb/dap: only include sourceReference if file path does not exist
	According to the DAP specification if the "sourceReference" field is
	included in a Source object, then the DAP client _must_ make a "source"
	request to the debugger to retrieve file contents, even if the Source
	object also includes path information.

	If the Source's path field is a valid path that the DAP client is able
	to read from the filesystem, having to make another request to the
	debugger to get the file contents is wasteful and leads to incorrect
	results (DAP clients will try to get the contents from the server and
	display those contents as a file with the name in "source.path", but
	this will conflict with the _acutal_ existing file at "source.path").

	Instead, only set "sourceReference" if the source file path does not
	exist.

	Not all breakpoints have a source location. For example, a breakpoint
	set on a raw address will have only the "address" field populated, but
	"source" will be None, which leads to a RuntimeError when attempting to
	unpack the filename and line number.

	Before attempting to unpack the filename and line number from the
	breakpoint, ensure that the source information is not None. Also
	populate the source and line information separately from the
	"instructionReference" field, so that breakpoints that include only an

	gdb/tui: add 'set tui mouse-events off' to restore mouse selection
	Rationale:
	I use the mouse with my terminal to select and copy text. In gdb, I use
	the mouse to select a function name to set a breakpoint, or a variable
	name to print, for example.

	When gdb is compiled with ncurses mouse support, gdb's TUI mode
	intercepts mouse events. Left-clicking and dragging, which would
	normally select text, seems to do nothing. This means I cannot select
	text using my mouse anymore. This makes it harder to set breakpoints,
	print variables, etc.

	Solution:
	I tried to fix this issue by editing the 'mousemask' call to only enable
	buttons 4 and 5. However, this still caused my terminal (gnome-terminal)
	to not allow text to be selected. The only way I could make it work is
	by calling 'mousemask (0, NULL);'. But doing so disables the mouse code
	entirely, which other people might want.

	I therefore decided to make a setting in gdb called 'tui mouse-events'.
	If enabled (the default), the behavior is as it is now: terminal mouse
	events are given to gdb, disabling the terminal's default behavior.
	If disabled (opt-in), the behavior is as it was before the year 2020:
	terminal mouse events are not given to gdb, therefore the mouse can be
	used to select and copy text.

	Notes:
	I am not attached to the setting name or its description. Feel free to
	suggest better wording.

	Testing:
	I tested this change in gnome-terminal by performing the following steps
	manually:

	1. Run: gdb --args ./myprogram
	2. Enable TUI: press ctrl-x ctrl-a
	3. Click and drag text with the mouse. Observe no selection.
	4. Input: set tui mouse-events off
	5. Click and drag text with the mouse. Observe that selection works now.
	6. Input: set tui mouse-events on.
	7. Click and drag text with the mouse. Observe no selection.

	[gdb/symtab] Error out for .debug_types section in dwz file
	There are two methods to factor out type information in a dwarf4 executable:
	- use -fdebug-info-types to generate type units in a .debug_types section, and
	- use dwz to create partial units.

	The dwz method has an extra benefit: it also allows to factor out information
	between executables into a newly created .dwz file, pointed to by a
	.gnu_debugaltlink section.

	There is nothing prohibiting a .gnu_debugaltlink file to contain a
	.debug_types section.

	It's just not generated by dwz or any other tool atm, and consequently gdb has
	no support for it.  Enhancement PR symtab/30838 is open about the lack of
	support.

	Make the current situation explicit by emitting a dwarf error:

	Handle pointers and references correctly in DAP
	A user pointed out that the current DAP variable code does not let the
	client deference a pointer.  Oops!

	Fixing this oversight is simple enough -- adding a new no-op
	pretty-printer for pointers and references is quite simple.

	However, doing this naive caused a regession in scopes.exp, which
	expected there to be no children of a 'const char *' variable.  This
	problem was fixed by the preceding patches in the series, which ensure
	that a C type of this kind is recognized as a string.

	Give a language to a type
	This changes main_type to hold a language, and updates the debug
	readers to set this field.  This is done by adding the language to the
	type-allocator object.

	Note that the non-DWARF readers are changed on a "best effort" basis.

	This patch also reimplements type::is_array_like to use the type's
	language, and it adds a new type::is_string_like as well.  This in
	turn lets us change the Python implementation of these methods to
	simply defer to the type.

	In one spot, it will be convenient for a subsequent patch if the CU is
	passed to a type-creation helper function.  In another spot, remove
	the redundant 'objfile' parameter to another such function.

	Pass a type allocator to init_fixed_point_type
	init_fixed_point_type currently takes an objfile and creates its own
	type allocator.  However, for a later patch it is more convenient if
	this function accepts a type allocator.  This patch makes this change.

	gdb/amdgpu: add precise-memory support
	The amd-dbgapi library exposes a setting called "memory precision" for
	AMD GPUs [1].  Here's a copy of the description of the setting:

	    The AMD GPU can overlap the execution of memory instructions with other
	    instructions.  This can result in a wave stopping due to a memory violation
	    or hardware data watchpoint hit with a program counter beyond the
	    instruction that caused the wave to stop.

	    Some architectures allow the hardware to be configured to always wait for
	    memory operations to complete before continuing.  This will result in the
	    wave stopping at the instruction immediately after the one that caused the
	    stop event.  Enabling this mode can make execution of waves significantly
	    slower.

	Expose this option through a new "amdgpu precise-memory" setting.

	The precise memory setting is per inferior.  The setting is transferred
	from one inferior to another when using the clone-inferior command, or
	when a new inferior is created following an exec or a fork.

	It can be set before starting the inferior, in which case GDB will
	attempt to apply what the user wants when attaching amd-dbgapi.  If the
	user has requested to enable precise memory, but it can't be enabled
	(not all hardware supports it), GDB prints a warning.

	If precise memory is disabled, GDB prints a warning when hitting a
	memory exception (translated into GDB_SIGNAL_SEGV or GDB_SIGNAL_BUS),
	saying that the stop location may not be precise.

	Note that the precise memory setting also affects memory watchpoint
	reporting, but the watchpoint support for AMD GPUs hasn't been
	upstreamed to GDB yet.  When we do upstream watchpoint support, GDB will
	produce a similar warning message when stopping due to a watchpoint if
	precise memory is disabled.

	Add a handful of tests.  Add a util proc
	"hip_devices_support_precise_memory", which indicates if all devices
	used for testing support that feature.

	arc: Fix alignment of the TLS Translation Control Block
	The R_ARC_TLS_LE_32 is defined as S + A + TLS_TBSS - TLS_REL, where

	  -  S is the base address of the symbol in the memory
	  -  A is the symbol addendum
	  -  TLS_TBSS is the TLS Translation Control Block size (aligned)
	  -  TLS_REL is the base of the TLS section

	Given the next code snip:

	__thread int data_var = 12;
	__attribute__((__aligned__(128))) __thread int data_var_128 = 128;
	__thread int bss_var;
	__attribute__((__aligned__(256))) __thread int bss_var_256;

	int __start(void)
	{
		return data_var + data_var_128 + bss_var + bss_var_256;
	}

	The current code returns different TLS_TBSS values for .tdata and
	.tbss. This patch fixes this by using the linker provided tls_sec.

	gdb: small cleanup in symbol_file_add_with_addrs
	While looking at how gdb::observers::new_objfile was used, I found
	some code in symbol_file_add_with_addrs that I thought could be
	improved.

	Instead of:

	  if (condition)
	   {
	     ...
	     return;
	   }

	  ...
	  return;

	Where some parts of '...' identical between the two branches.  I think
	it would be nicer if the duplication is removed, and we just use:

	  if (!condition)
	    ...

	to guard the one statement that should only happen when the condition
	is not true.

	There is one change in this commit though that is (possibly)
	significant, there is a call to bfd_cache_close_all() that was only
	present in the second block.  After this commit we now call that
	function for both paths.

	The call to bfd_cache_close_all was added in commit:

	  commit ce7d45220e4ed342d4a77fcd2f312e85e1100971
	  Date:   Fri Jul 30 12:05:45 2004 +0000

	with the purpose of ensuring that GDB doesn't hold the BFDs open
	unnecessarily, thus preventing the files from being updated on some
	hosts (e.g. Win32).

	In the early exit case we previously didn't call bfd_cache_close_all,
	with the result that GDB would continue to hold open some BFD objects
	longer than needed.

	After this commit, but calling bfd_cache_close_all for both paths this
	problem is solved.

	I'm not sure how this change could be tested, I don't believe there's
	any GDB (maintenance) command that displays the BFD cache contents, so
	we can't check the cache contents easily.  Ideas are welcome though.

	Throw error when creating an overly large gdb-index file
	The header in a .gdb_index section uses 32-bit unsigned offsets to
	refer to other areas of the section.  Thus, there is a size limit of
	2^32-1 which is currently unaccounted for by GDB's code for outputting
	these sections.

	At the moment, when GDB creates an overly large section, it will exit
	abnormally due to an internal error, which is caused by a failed
	assert in assert_file_size, which in turn is called from
	write_gdbindex_1, both of which are in gdb/dwarf2/index-write.c.

	This is what happens when that assert fails:

	This problem was encountered while building the python-graph-tool
	package on Fedora.  The Fedora bugzilla bug can be found here:

	https://bugzilla.redhat.com/show_bug.cgi?id=1773651

	This commit prevents the internal error from occurring by calling error()
	when the file size exceeds 2^32-1.

	Using a gdb built with this commit, I now see this behavior instead:

	$ gdb -q -nx -iex 'set auto-load no' -iex 'set debuginfod enabled off' -ex file ./libgraph_tool_inference.so -ex "save gdb-index `pwd`/"
	Reading symbols from ./libgraph_tool_inference.so...
	No executable file now.
	Discard symbol table from `/mesquite2/fedora-bugs/1773651/libgraph_tool_inference.so'? (y or n) n
	Not confirmed.
	Error while writing index for `/mesquite2/fedora-bugs/1773651/libgraph_tool_inference.so': gdb-index maximum file size of 4294967295 exceeded
	(gdb)

	I wish I could provide a test case, but due to the sizes of both the
	input and output files, I think that testing resources would be
	strained or exceeded in many environments.

	My testing on Fedora 38 shows no regressions.

	gdb: fix buffer overflow in DWARF reader
	In this commit:

	  commit 48ac197b0c209ccf1f2de9704eb6cdf7c5c73a8e
	  Date:   Fri Nov 19 10:12:44 2021 -0700

	      Handle multiple addresses in call_site_target

	a buffer overflow bug was introduced when the following code was
	added:

	  CORE_ADDR *saved = XOBNEWVAR (&objfile->objfile_obstack, CORE_ADDR,
	                                addresses.size ());
	  std::copy (addresses.begin (), addresses.end (), saved);

	The definition of XOBNEWVAR is (from libiberty.h):

	  #define XOBNEWVAR(O, T, S)	((T *) obstack_alloc ((O), (S)))

	So 'saved' is going to point to addresses.size () bytes of memory,
	however, the std::copy will write addresses.size () number of
	CORE_ADDR sized entries to the address pointed to by 'saved', this is
	going to result in memory corruption.

	The mistake is that we should have used XOBNEWVEC, which allocates a
	vector of entries, the definition of XOBNEWVEC is:

	  #define XOBNEWVEC(O, T, N) \
	    ((T *) obstack_alloc ((O), sizeof (T) * (N)))

	Which means we will have set aside enough space to create a copy of
	the contents of the addresses vector.

	I'm not sure how to create a test for this problem, this issue cropped
	up when debugging a particular i686 built binary, which just happened
	to trigger a glibc assertion (likely due to random memory corruption),
	debugging the same binary built for x86-64 appeared to work just fine.

	Using valgrind on the failing GDB binary pointed straight to the cause
	of the problem, and with this patch in place there are no longer
	valgrind errors in this area.

	If anyone has ideas for a test I'm happy to work on something.

	[gdb/exp] Clean up asap in value_print_array_elements
	I've been running the test-suite on an i686-linux laptop with 1GB of memory,
	and 1 GB of swap, and noticed problems after running gdb.base/huge.exp: gdb
	not being able to spawn for a large number of test-cases afterwards.

	So I investigated the memory usage, on my usual x86_64-linux development
	platform.

	The test-case is compiled with -DCRASH_GDB=2097152, so this:
	...
	static int a[CRASH_GDB], b[CRASH_GDB];
	...
	with sizeof (int) == 4 represents two arrays of 8MB each.

	Say we add a loop around the "print a" command and print space usage
	statistics:
	...
	gdb_test "maint set per-command space on"
	for {set i 0} {$i < 100} {incr i} {
	    gdb_test "print a"
	}
	...

	This gets us:
	...
	(gdb) print a^M
	$1 = {0 <repeats 2097152 times>}^M
	Space used: 478248960 (+469356544 for this command)^M
	(gdb) print a^M
	$2 = {0 <repeats 2097152 times>}^M
	Space used: 486629376 (+8380416 for this command)^M
	(gdb) print a^M
	$3 = {0 <repeats 2097152 times>}^M
	Space used: 495009792 (+8380416 for this command)^M
	  ...
	(gdb) print a^M
	$100 = {0 <repeats 2097152 times>}^M
	Space used: 1308721152 (+8380416 for this command)^M
	...

	In other words, we start out at 8MB, and the first print costs us about 469MB,
	and subsequent prints 8MB, which accumulates to 1.3 GB usage. [ On the
	i686-linux laptop, the first print costs us 335MB. ]

	The subsequent 8MBs are consistent with the values being saved into the value
	history, but the usage for the initial print seems somewhat excessive.

	There is a PR open about needing sparse representation of large arrays
	(PR8819), but this memory usage points to an independent problem.

	The function value_print_array_elements contains a scoped_value_mark to free
	allocated values in the outer loop, but it doesn't prevent the inner loop from
	allocating a lot of values.

	Fix this by adding a scoped_value_mark in the inner loop, after which we have:
	...
	(gdb) print a^M
	$1 = {0 <repeats 2097152 times>}^M
	Space used: 8892416 (+0 for this command)^M
	(gdb) print a^M
	$2 = {0 <repeats 2097152 times>}^M
	Space used: 8892416 (+0 for this command)^M
	(gdb) print a^M
	$3 = {0 <repeats 2097152 times>}^M
	Space used: 8892416 (+0 for this command)^M
	  ...
	(gdb) print a^M
	$100 = {0 <repeats 2097152 times>}^M
	Space used: 8892416 (+0 for this command)^M
	...

	Note that the +0 here just means that the mallocs did not trigger an sbrk.
	This is dependent on malloc (which can use either mmap or sbrk or some
	pre-allocated memory) and will likely vary between different tunings, versions
	and implementations, so this does not give us a reliable way detect the
	problem in a minimal way.

	A more reliable way of detecting the problem is:
	...
	 void
	 value_free_to_mark (const struct value *mark)
	 {
	+  size_t before = all_values.size ();
	   auto iter = std::find (all_values.begin (), all_values.end (), mark);
	   if (iter == all_values.end ())
	     all_values.clear ();
	   else
	     all_values.erase (iter + 1, all_values.end ());
	+  size_t after = all_values.size ();
	+  if (before - after >= 1024)
	+    fprintf (stderr, "value_free_to_mark freed %zu items\n", before - after);
	...
	which without the fix tells us:
	...
	+print a
	value_free_to_mark freed 2097152 items
	$1 = {0 <repeats 2097152 times>}
	...

	Fix a similar problem for Fortran:
	...
	+print array1
	value_free_to_mark freed 4194303 items
	$1 = (0, <repeats 2097152 times>)
	...
	in fortran_array_printer_impl::process_element.

	The problem also exists for Ada:
	...
	+print Arr
	value_free_to_mark freed 2097152 items
	$1 = (0 <repeats 2097152 times>)
	...
	but is fixed by the fix for C.

	Add Fortran and Ada variants of the test-case.  The *.exp files are similar
	enough to the original to keep the copyright years range.

	While writing the Fortran test-case, I ran into needing an additional print
	setting to print the entire array in repeat form, filed as PR exp/30817.

	I managed to apply the compilation loop for the Ada variant as well, but with
	a cumbersome repetition style.  I noticed no other test-case uses gnateD, so
	perhaps there's a better way of implementing this.

	The regression test included in the patch is formulated in its weakest
	form, to avoid false positive FAILs, which also means that smaller regressions
	may not get detected.

	Tested on x86_64-linux.

	x86: Vxy naming correction
	Looking at the VEX and EVEX forms of vcvtneps2bf16 I noticed that
	operand purpose isn't properly reflected in Vxy's definition. Rename
	"dst" to "src", thus bringing things in line with Exy.

	x86: support AVX10.1 vector size restrictions
	Recognize "/<number>" suffixes on both -march=+avx10.1 and the
	corresponding .arch directive, setting an upper bound on the vector size
	that insns may use. Such a restriction can be reset by setting a new base
	architecture, by using a suffix-less form, by disabling AVX10, or by
	enabling any other VEX/EVEX-based vector extension.

	While for most insns we can suppress their use with too wide operands
	via registers becoming unavailable (or in Intel syntax memory operand
	size specifiers not being recognized), mask register insns have to have
	their minimum required vector size specified in a new attribute. (Of
	course this new attribute could also be used on other insns.)

	Note that .insn continues to be permitted to emit EVEX{512,256} (and
	VEX256 ones) encodings regardless of vector size restrictions in place.
	Of course these can't be expressed using zmm (or ymm) operands then,
	but need using the EVEX.512.* forms (broadcast forms may be usable right
	now, but this may go away so shouldn't be relied upon). This is why no
	assertions should be added to build_{e,}vex_prefix().

	x86: support AVX10.1/512
	Since this is merely a re-branding of certain AVX512* features, there's
	little code to be added.

	The main aspect here are new testcases. In order to be able to re-use
	some of the existing testcases, several of them need their start symbols
	adjusted. Note that 256- and 128-bit tests want adding here, as these
	need to work right away. Subsequently they'll gain vector length
	constraints.

	Since it was missing and is wanted here, also add an AVX512VL+VPOPCNTDQ
	test.

2023-09-14  Jan Beulich  <jbeulich@suse.com>

	x86: make AES/PCMULQDQ respectively prereqs of VAES/VPCMULQDQ
	These probably should have been put in place already anyway, but they're
	very much wanted in order to then put AVX10.1 support on top. Note that
	to avoid reverse dependencies towards SSE (just like we already do for
	AVX and XOP), add_isa_dependencies() needs some further tweaking.

	While there also address a related anomaly: Disabling AES but neither
	AVX nor VAES (similarly for {,V}PCLMULQDQ) would better keep the 128-bit
	VEX-encoded forms available. Note that for this the VAES insns are moved
	past the AVX+AES ones, to avoid the property-11 test suddenly failing.
	The test really is wrong, but let's not also make things inconsistent:
	Without the movement, YMM use would be correctly recorded for the
	128-bit forms simply because the first template already matches, as long
	as VAES wasn't disabled.  Yet it still wouldn't be if only AVX+AES were
	enabled. Nor would behavior here then be the same as for VPCLMUL* insns.

	gdb: Fix -Wuninitialized issue

	gdb/testsuite: fix gdb.arch/amd64-init-x87-values.exp on AMD CPUs
	I see the following failure when running this test on an AMD machine:

	    p/x $fioff^M
	    $24 = 0x0^M
	    (gdb) FAIL: gdb.arch/amd64-init-x87-values.exp: check_x87_regs_around_init: check post FLD1 value of $fioff

	The register that GDB calls fioff normally contains the address of the
	last instruction executed by the x87 unit.  It is available through the
	FSAVE/FXSAVE/XSAVE instructions, at offset 0x8 of the FSAVE/FXSAVE/XSAVE
	area.  You can read about it in the Intel manual [1] at section "10.5.1
	FXSAVE Area" (and equivalent sections for FSAVE and XSAVE) or in the AMD
	manual [2] at section "11.4.4 Saving Media and x87 Execution Unit
	State".

	The test therefore expects that after executing the FLD1 instruction,
	the fioff register contains the address of the FLD1 instruction.

	However, the FXSAVE and XSAVE instructions (which the kernel uses to
	dump x87 register state which it provides GDB through ptrace) behave
	differently on AMD CPUs.  In section "11.4.4.3 FXSAVE and FXRSTOR
	Instructions" of the AMD manual, we read:

	    The FXSAVE and FXRSTOR instructions save and restore the entire
	    128-bit media, 64-bit media, and x87 state. These instructions
	    usually execute faster than FSAVE/FNSAVE and FRSTOR because they do
	    not normally save and restore the x87 exception pointers
	    (last-instruction pointer, last data-operand pointer, and last
	    opcode). The only case in which they do save the exception pointers
	    is the relatively rare case in which the exception-summary bit in
	    the x87 status word (FSW.ES) is set to 1, indicating that an
	    unmasked exception has occurred.

	So, unless a floating point exception happened and that exception is
	unmasked in the x87 FPU control register (which isn't by default on
	Linux, from what I saw), the "last instruction address" register (or
	fioff as GDB calls it) will always be 0 on an AMD CPU.

	For this reason, I think it's fine to change the test to accept the
	value 0 - that's just how the processor works.

	I toyed with the idea of changing the test program to make it so the CPU
	would generate a non-zero fioff.  That is by unmasking an FPU exception
	and executing an instruction to raise that kind exception.  It worked,
	but then I would have to change the test more extensively, and it didn't
	seem to be worth it.

	gdb/doc: describe x87 registers
	While investigating this [1], I initially had no idea what register
	"fioff" stood for, making it difficult to map it to something in the
	Intel or AMD manuals.  Similarly, I can imaging someone familiar with
	x87 to want to print the "x87 last instruction address", and have no
	clue that GDB makes it available as register "fioff".  The names of the
	x87 state fields don't seem to be standardized, they even change between
	sections of the Intel manual (between the FSAVE, FXSAVE and XSAVE area
	descriptions).

	Add some details to the doc to help one map GDB register names to x87
	state fields.

	gdb/doc: rename "x86 Architecture-specific Issues" section to "x86"
	I'm looking to add some x86-specific information to the doc, but I find
	the naming of this section odd.  It doesn't really talk about issues, it
	just gives generally useful information.  Also, the sections about other
	architectures don't mention "issues", just the architecture name.

	Also, at least in the HTML version of the doc, the name is inconsistent
	between the main table of content, where it appears as "x86
	Architecture-specific Issues", and the sub-table of contents of the
	"Architectures" section, where it appears as "i386".

	Rename the section to just "x86".

	gdb/testsuite: fix gdb.mi/mi-condbreak-throw.exp failure
	In commit:

	  commit 3ce8f906be7a55d8c0375e6d360cc53b456d86ae
	  Date:   Tue Aug 8 10:45:20 2023 +0100

	      gdb: MI stopped events when unwindonsignal is on

	a new test, gdb.mi/mi-condbreak-throw.exp, was added.  Unfortunately,
	this test would fail when using the native-gdbserver board (and other
	similar boards).

	The problem was that one of the expected output patterns included some
	output from the inferior.  When using the native-gdbserver board, this
	output is not printed to GDB's tty, but is instead printed to
	gdbserver's tty, the result is that the expected output no longer
	matches, and the test fails.

	Additionally, as the output is actually from the C++ runtime, rather
	than the test's source file, changes to the C++ runtime could cause
	the output to change.

	To solve both of these issues, in this commit, I'm removing the
	reference to the inferior's output, and replacing it with '.*', which
	will skip the output if it is present, but is equally happy if the
	output is not present.

	After this commit gdb.mi/mi-condbreak-throw.exp now passes on all
	boards, including native-gdbserver.

	testsuite, fortran: adapt tests for ifort's 'start' behavior
	The modified tests array-slices-bad.exp and vla-type.exp both set a
	breakpoint at the first real statement in the respective executables.

	Normally, the expected behavior of fortran_runto_main for these would be
	the stopping of the debugger at exactly the first statment in the code.

	Strangely, neither gfortran nor ifx seem to do this for these tests.
	Instead, issuing 'start' in ifx (for either of the 2 tests) lets GDB
	stop at the 'program ...' line and gfortran stops at a variable
	declaration line.  E.g. for vla-type it stops at

	  41        type(five)               :: fivearr (2)

	So, actually, ifort's behavior can be considered to be a bit more
	'correct' here.  This patch remove the fortran_runto_main in the
	two tests and instead uses runto to directly run to the first breakpoint
	set at the first program statement.  This works with both compiler
	behaviors and makes the tests more robust.

	testsuite, fortran: Remove self assignment non-statements
	There were a couple of places in the testsuite where instructions like

	  var = var

	were written in the source code of tests.  These were usually dummy
	statements meant to generate a line table entry at that line on which
	to break later on.

	This worked fine for gfortran and ifx, but it seems that, when compiled
	with ifort (2021.6.0) these statements do not actually create any
	assmbler instructions and especially no line table entries.  Consider
	the program

	  program test
	    Integer var :: var = 1
	    var = var
	  end program

	compiled with gfortran (13.0.0, -O0 -g).  The linetable as emitted by
	'objdump --dwarf=decodedline ./a.out' looks like

	  test.f90:
	  File name   Line number    Starting address    View    Stmt
	  test.f90              1            0x401172               x
	  test.f90              3            0x401176               x
	  test.f90              4            0x401182               x
	  test.f90              4            0x401185               x
	  test.f90              4            0x401194               x
	  test.f90              -            0x4011c0

	actually containing line table info for line 3.  Running gdb, breaking
	at 3 and checking the assembly we see

	   0x0000000000401172 <+0>:     push   %rbp
	   0x0000000000401173 <+1>:     mov    %rsp,%rbp
	=> 0x0000000000401176 <+4>:     mov    0x2ebc(%rip),%eax   # 0x404038 <var.1>
	   0x000000000040117c <+10>:    mov    %eax,0x2eb6(%rip)   # 0x404038 <var.1>
	   0x0000000000401182 <+16>:    nop
	   0x0000000000401183 <+17>:    pop    %rbp
	   0x0000000000401184 <+18>:    ret

	so two mov instructions are being issued for this assignment one copying
	the value into a register and one writing it back to the same memory.
	Ifort (2021.6.0, -O0 -g) on the other hand does not emit anything here
	and also has no line table entry:

	  test.f90:
	  File name   Line number    Starting address    View    Stmt
	  test.f90              1            0x4040f8               x
	  test.f90              4            0x404109               x
	  test.f90              4            0x40410e               x
	  test.f90              -            0x404110

	As I do not think that this is really a bug (on either side, gfortran/ifx or
	ifort), and as I don't think this behavior is covered in the Fortran
	standard, I changed these lines to become actual value assignments.

	This removes a few FAILs in the testsuite when ran with ifort.

	testsuite, fortran: make mixed-lang-stack less compiler dependent
	In the gdb.fortran/mixed-lang-stack.exp test when somewhere deep in a
	bunch of nested function calls we issue and test a 'info args' command
	for the mixed_func_1b function (when in that function's frame).

	The signature of the function looks like

	  subroutine mixed_func_1b(a, b, c, d, e, g)
	    use type_module
	    implicit none

	    integer :: a
	    real(kind=4) :: b
	    real(kind=8) :: c
	    complex(kind=4) :: d
	    character(len=*) :: e
	    character(len=:), allocatable :: f
	    TYPE(MyType) :: g

	and usually one would expect arguments a, b, c, d, e, and g to be
	emitted here.  However, due to some compiler dependent treatment of the
	e array the actual output in the test (with gfortran/ifx) is

	  (gdb) info args
	  a = 1
	  b = 2
	  c = 3
	  d = (4,5)
	  e = 'abcdef'
	  g = ( a = 1.5, b = 2.5 )
	  _e = 6

	where the compiler generated '_e' is emitted as the length of e.  While
	ifort also generates an additional length argument, the naming (which is
	up to the compilers here I think, I could not find anything in the
	Fortran standard about this) is different and we see

	  (gdb) info args
	  a = 1
	  b = 2
	  c = 3
	  d = (4,5)
	  e = 'abcdef'
	  g = ( a = 1.5, b = 2.5 )
	  .tmp.E.len_V$4a = 6

	To make both outputs pass the test, I kept the additional argument for now and
	made the regex for the emitted name of the last variable match any
	arbitrary name.

	Simplify block_find_symbol
	block_find_symbol takes a callback function, but only two callbacks
	are ever passed to it -- and they are similar enough that it seems
	cleaner to just have block_find_symbol do the work itself.  Also,
	block_find_symbol can take a lookup_name_info as an argument,
	following the general idea of pushing the construction of these
	objects as high in the call chain as feasible.

	gdb/mi: make current_token a field of mi_interp
	Following the commit f818c32ba459 ("gdb/mi: fix ^running record with
	multiple MI interpreters"), I thought it would make sense to make
	current_token a field of mi_interp.  This variable contains the token of
	the currently handled MI command, like the 222 in:

	    222-exec-continue

	I didn't find any bug related to that, it's just a "that seems nicer"
	cleanup, since the current token is a fundamentally per-interp thing.

	mi_execute_command needs a check similar to what we already have in
	mi_cmd_gdb_exit: when invoked from Python's gdb.execute_mi, the current
	interpreter is not an mi_interp.  When using the Python gdb.execute_mi
	function, there is no such concept of token, so we can just skip that.

	There should be no user-visible change.

	[gdb/testsuite] Fix gdb.ada/same_enum.exp
	Test-case gdb.ada/same_enum.exp is supposed to be a regression test for this
	bit of code in remove_extra_symbols:
	...
	  if (symbols_are_identical_enums (syms))
	    syms.resize (1);
	...

	The test-case does "print red" and expects one of these two choices to be
	picked by remove_extra_symbols:
	...
	  type Color is (Black, Red, Green, Blue, White);
	  type RGB_Color is new Color range Red .. Blue;
	...
	but because only the type Color is used:
	...
	  FC : Color := Red;
	  SC : Color := Green;
	...
	the RGB_Color type is eliminated from the debug info, and consequently
	remove_extra_symbols has no effect for the test-case.

	In other words, we have:
	...
	(gdb) ptype Color ^M
	type = (black, red, green, blue, white)^M
	(gdb) ptype RGB_Color^M
	No definition of "rgb_color" in current context.^M
	...

	Fix this by changing the type of SC to RGB_Color, and add prints of the two
	types to check that they're both available.

	With the test-case fixed, if we disable the bit of code in
	remove_extra_symbols we get:
	...
	(gdb) print red^M
	Multiple matches for red^M
	[0] cancel^M
	[1] pck.color'(pck.red) (enumeral)^M
	[2] pck.rgb_colorB'(pck.red) (enumeral)^M
	> FAIL: gdb.ada/same_enum.exp: print red (timeout)
	...
	in other words, the test-case now properly functions as a regression test.

	Tested on x86_64-linux.

	2^M
	(gdb) PASS: gdb.python/py-symbol.exp: \
	  print (len (gdb.lookup_static_symbols ('rr')))

	The problem is that the loop in gdbpy_lookup_static_symbols loops over compunits
	representing both CUs and PUs:
	...
	 	  for (compunit_symtab *cust : objfile->compunits ())
	...

	When doing a lookup on a PU, the user link is followed until we end up at a CU,
	and the lookup is done in that CU.

	In other words, when doing a lookup in the loop for a PU we duplicate the
	lookup for a CU that is already handled by the loop.

	Handle array- and string-like values in no-op pretty printers
	This changes the no-op pretty printers -- used by DAP -- to handle
	array- and string-like objects known by the gdb core.  Two new tests
	are added, one for Ada and one for Rust.

2023-09-05  Tom Tromey  <tromey@adacore.com>

	Add new Python APIs to support DAP value display
	gdb's language code may know how to display values specially.  For
	example, the Rust code understands that &str is a string-like type, or
	Ada knows how to handle unconstrained arrays.  This knowledge is
	exposed via val-print, and via varobj -- but currently not via DAP.

	This patch adds some support code to let DAP also handle these cases,
	though in a somewhat more generic way.

	Type.is_array_like and Value.to_array are added to make Python aware
	of the cases where gdb knows that a structure type is really
	"array-like".

	Type.is_string_like is added to make Python aware of cases where gdb's
	language code knows that a type is string-like.

	Unlike Value.string, these cases are handled by the type's language,
	rather than the current language.

	Select frame when fetching a frame variable in DAP
	Right now, if a program uses multiple languages, DAP value formatting
	will always use the language of the innermost frame.  However, it is
	better to use the variable's defining frame instead.  This patch does
	this by selecting the frame first.

	This also fixes a possibly latent bug in the "stepOut" command --
	"finish" is sensitive to the selected frame, but the DAP code may
	already select other frames when convenient.  The DAP stepOut request
	only works on the newest frame, so be sure to select it before
	invoking "finish".

	Introduce type::is_array_like and value_to_array
	This adds the type::is_array_like method and the value_to_array
	function.

	The former can be used to see whether a given type is known to be
	"array-like".  This is the currently the case for certain
	compiler-generated structure types; in particular both the Ada and
	Rust compilers do this.

	Use ada_value_subscript in valpy_getitem
	Ada has a few complexities when it comes to array handling.  Currently
	these are all handled in Ada-specific code -- but unfortunately that
	means they aren't really accessible to Python.

	This patch changes the Python code to defer to Ada when given an Ada
	array.  In order to make this work, one spot in ada-lang.c had to be
	updated to set the "GNAT-specific" flag on an array type.

	The test case for this will come in a later patch.

	Note that the size of the type_specific_field bitfield had to be

	This moves rust_language::lookup_symbol_nonlocal to rust-lang.c.

	Read Ada main name from executable, not inferior
	An upstream bug report points out this bug: if the user switches from

	"start" command will fail.

	What happens here is that the Ada "main" name is found in a constant
	string in the executable.  But, if the inferior is running, then the
	process_stratum target reads from the inferior memory.

	This patch fixes the problem by changing the main name code to set
	trust-readonly-sections, causing the target stack to read from the

	RISC-V: Prohibit combination of 'E' and 'H'
	According to the ratified privileged specification (version 20211203),
	it says:

	> The hypervisor extension depends on an "I" base integer ISA with 32 x
	> registers (RV32I or RV64I), not RV32E, which has only 16 x registers.

	Also in the latest draft, it also prohibits RV64E with the 'H' extension.
	This commit prohibits the combination of 'E' and 'H' extensions.

	[gdb/testsuite] Fix race in gdb.base/add-symbol-file-attach.exp
	When running test-case gdb.base/add-symbol-file-attach.exp with target board
	unix/-m32, we run into:
	...
	(gdb) attach 3955^M
	Attaching to process 3955^M
	Load new symbol table from "add-symbol-file-attach"? (y or n) y^M
	Reading symbols from add-symbol-file-attach/add-symbol-file-attach...^M

	0xf7f53549 in __kernel_vsyscall ()^M
	(gdb) FAIL: gdb.base/add-symbol-file-attach.exp: attach
	...

	The test fails because this regexp is used:
	...
	    -re ".*in \[_A-Za-z0-9\]*pause.*$gdb_prompt $" {
	...

	The regexp attempts to detect that the exec is somewhere in pause ():
	...
	int
	main (int argc, char **argv)
	{
	  pause ();
	  return 0;
	}
	...
	but when the exec is blocked in pause, the backtrace is:
	...
	 (gdb) bt
	 #0  0xf7fd2549 in __kernel_vsyscall ()
	 #1  0xf7d84966 in __libc_pause () at ../sysdeps/unix/sysv/linux/pause.c:29
	 #2  0x0804844c in main (argc=1, argv=0xffffce84)
	     at /data/vries/gdb/src/gdb/testsuite/gdb.base/add-symbol-file-attach.c:26
	...

	We could simply extend the regexp to also match __kernel_vsyscall, but the
	more fundamental problem is that the test is racy.

	The attach can happen before the exec is blocked in pause (), somewhere in the
	dynamic linker resolving the call to pause, in main or even earlier.

	Note that for the test-case to be effective, the exec is not required to be in
	pause ().  I added a "while (1);" loop at the start of main, reverted the
	patch fixing the corresponding PR and reproduced the problem it's supposed to
	detect.

	Fix this by simply matching the "Reading symbols from" line, similar to what
	an earlier test is doing.

	While we're at it, rewrite the earlier test to also use the -wrap idiom.

	Tested on x86_64-linux.

	gdbserver: i387_cache_to_xsave: fix copy dest of zmm registers
	On a machine with AVX512 support (AMD EPYC 9634), I see these failures:

	    $ make check TESTS="gdb.arch/i386-avx512.exp" RUNTESTFLAGS="--target_board=native-gdbserver"
	    ...
	    FAIL: gdb.arch/i386-avx512.exp: check contents of zmm_data[16] after writing ZMM regs
	    FAIL: gdb.arch/i386-avx512.exp: check contents of zmm_data[17] after writing ZMM regs
	    FAIL: gdb.arch/i386-avx512.exp: check contents of zmm_data[18] after writing ZMM regs
	    ...

	The problem can be reduced to:

	    (gdb) print $zmm16.v8_int64
	    $1 = {0, 0, 0, 0, 0, 0, 0, 0}
	    (gdb) print $zmm16.v8_int64 = {11,22,33,44,55,66,77,88}
	    $2 = {11, 22, 33, 44, 55, 66, 77, 88}
	    (gdb) print $zmm16.v8_int64
	    $3 = {11, 22, 33, 44, 55, 66, 77, 88}
	    (gdb) step
	    5               ++x;
	    (gdb) print $zmm16.v8_int64
	    $4 = {11, 22, 77, 88, 0, 0, 0, 0}

	Writing to the local regcache in GDB works fine, but the writeback to
	gdbserver (which happens when resuming / stepping) doesn't work (the
	code being stepped doesn't touch AVX registers, so we don't expect the
	value of zmm16 to change when stepping).

	The problem is on the gdbserver side, the zmmh and ymmh portions of the
	zmm register are not memcpied at the right place in the xsave buffer.  Fix
	that.  Note now how the two modified memcpy calls match the memcmp calls
	just above them.

	With this patch, gdb.arch/i386-avx512.exp passes completely for me.

	config: Fix host -rdynamic detection for build != host != target
	[Merge from GCC commit 4d9bc81a5d8d884dee7a7781fa4c1577a6c9681a.]

	The GCC_ENABLE_PLUGINS configure logic for detecting whether -rdynamic
	is necessary and supported uses an appropriate objdump for $host
	binaries (running on $build) in cases where $host is $build or
	$target.

	However, it is missing such logic in the case where $host is neither
	$build nor $target, resulting in the compilers not being linked with
	-rdynamic and plugins not being usable with such a compiler.  In fact
	$ac_cv_prog_OBJDUMP, as used when $build = $host, is always an objdump
	for $host binaries that runs on $build; that is, it's appropriate to
	use in this case as well.

	Tested in such a configuration that it does result in cc1 being linked
	with -rdynamic as expected.  Also bootstrapped with no regressions for
	x86_64-pc-linux-gnu.

	config/
		* gcc-plugin.m4 (GCC_ENABLE_PLUGINS): Use

	[symtab/27831] Fix OBJF_MAINLINE assert
	This commit fixes a bug mentioned by Florian Weimer during the
	libpthread/ld.so load order discussion from 2021.  Florian provided
	instructions for reproducing the bug here:

	https://sourceware.org/pipermail/gdb-patches/2021-April/177923.html

	That particular test does some interesting things involving forks,
	threads, and thread local storage.  Fortunately, none of that is
	needed to reproduce the problem.

	I've made a new test case (which is now found in a separate commit)
	contained in the files gdb.base/add-symbol-file-attach.{c,exp}.  The
	.c file is fairly simple as is the recipe for reproducing the problem.

	After separately starting the test case and noting the process id,
	start gdb (w/ no arguments), and do the following to reproduce the
	assertion failure - for this run, the process id of the separately
	started add-symbol-file-attach process is 4103218:

	(gdb) add-symbol-file add-symbol-file-attach
	add symbol table from file "add-symbol-file-attach"
	(y or n) y
	Reading symbols from add-symbol-file-attach...
	(gdb) attach 4103218
	Attaching to process 4103218
	Load new symbol table from "/tmp/add-symbol-file-attach"? (y or n) y
	Reading symbols from /tmp/add-symbol-file-attach...

	(No debugging symbols found in /lib64/libc.so.6)
	Reading symbols from /lib64/ld-linux-x86-64.so.2...
	(No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
	0x00007f502130bf27 in pause () from /lib64/libc.so.6
	(gdb) p foo
	symtab.c:6417: internal-error: CORE_ADDR get_msymbol_address(objfile*,
	  const minimal_symbol*): Assertion `(objf->flags & OBJF_MAINLINE) == 0'
	  failed.
	A problem internal to GDB has been detected,
	further debugging may prove unreliable.

	The add-symbol-file command causes the symbols to be loaded without
	the SYMFILE_MAINLINE (and hence the OBJFILE_MAINLINE) flags being
	set.  This, in turn, causes the "maybe_copied" flag to be set for
	the global symbol (named "foo" in the provided test case).

	The attach command will cause another objfile to be created, but
	it will reuse the symtabs from the objfile created by add-symbol-file,
	leading to a situation in which the OBJFILE_MAINLINE flag will be set
	for the new (attach-created) objfile, however the "maybe_copied"
	flag will still be set for the global symbol.  Had it been loaded
	anew, this flag would not be set due to OBJFILE_MAINLINE being set
	for the objfile.

	At present, minimal_symbol::value_address looks like this:

	CORE_ADDR
	minimal_symbol::value_address (objfile *objfile) const
	{
	  if (this->maybe_copied (objfile))
	    return get_msymbol_address (objfile, this);
	  else
	    return (CORE_ADDR (this->unrelocated_address ())
		    + objfile->section_offsets[this->section_index ()]);
	}

	So, we can now see the problem: When the "maybe_copied" flag is set,
	get_msymbol_address() will be called.  However, get_msymbol_address()
	assumes that it won't be called with the OBF_MAINLINE flag set for
	the objfile in question.  It, in fact, contains an assert() which
	makes sure that this is the case:

	  gdb_assert ((objf->flags & OBJF_MAINLINE) == 0);

	(If this assert is removed, then get_msymbol_address() recurses
	infinitely for the case under consideration.)

	So, the problem here is that the maybe_copied flag is set for the
	symbol AND the OBJF_MAINLINE flag is set for the objfile.  As noted
	earlier, this happens due to add-symbol-file being used; this causes
	the maybe_copied flag to be set.  Later, when the attach is performed,
	OBJF_MAINLINE will be set for that objfile, leading to this
	unfortunate situation.

	My first cut at a solution involved adjusting the
	MSYMBOL_VALUE_ADDRESS macro (which has since been changed to be the
	method noted above) to include a test of the OBJFILE_MAINLINE flag.
	However, Simon Marchi, in his review of my patch, suggested a better
	solution.  Simon observed that the 'maybe_copied' flag is (was, after
	this commit) being set/initialized in record_minimal_symbol() using
	using the objfile in the context in which the symbol was created.

	Simon further observed:

	  Today, a single copy is created, as symtabs are shared between
	  objfiles.  This means that everything that we store into a symbol
	  must be independent of any objfile.  However, the value of the
	  maybe_copied field is dependent on the objfile in the context of
	  which the symbol was created.  Meaning that when the symbol is
	  re-used in the context of another objfile, the maybe_copied value is
	  not right in the context of that objfile.

	  So I think it means there isn't a single "is this symbol maybe
	  copied" value, but instead "is this symbol maybe copied, in the
	  context of this given objfile".  And the answer is yes or no,
	  depending on whether the objfile is mainline.  So maybe_copied
	  should become a method that takes an objfile and returns an answer
	  based on that.

	Simon's full review can be found here:

	  https://sourceware.org/pipermail/gdb-patches/2021-May/178855.html

	Simon also provided a patch which implements this suggestion.  The
	current patch is mostly his work, though I did make some adjustments
	during a rebase in addition to making some changes to account for a
	concern from Tom Tromey.

	During his review of the v3 series, Tom noted, "The old approach was
	specific to ELF, while the new approach will be used by any object
	format." Tom further observed, "...it seems like it could result in an
	incorrect evaluation in some scenario."  This seemed plausible to me,
	so I introduced the flag 'object_format_has_copy_relocs' to struct
	objfile.  It is set at the end of elf_symfile_read() in elfread.c.
	The minimal_symbol::maybe_copied method tests this new flag, forcing
	this method to return false when the flag is not set.  If we find that
	other object file formats use the same copy reloc mechanism as ELF,
	then 'object_format_has_copy_relocs' should be set for objfiles using
	those formats.

	Lastly, I'll note that this is a strange use case.  It's far more
	common to either let gdb figure out which file to load by itself when
	attaching, i.e.

	(gdb) attach 4104360
	Attaching to process 4104360
	Reading symbols from /tmp/add-symbol-file-attach...
	Reading symbols from /lib64/libc.so.6...

	Reading symbols from /lib64/ld-linux-x86-64.so.2...

	0x00007fdb1fc33f27 in pause () from /lib64/libc.so.6
	(gdb) p foo
	$1 = 42

	...or to use the "file" command prior to the attach, like this:

	(gdb) file add-symbol-file-attach
	Reading symbols from add-symbol-file-attach...
	(gdb) attach 4104360

	Revert "Simplify @node use in BFD documentation"
	This reverts commit 8bb23cdbb498ff645bb0937bc8c0cb89e9e5ebd8.

	My earlier patch to simplifify the @node uses in the BFD manual didn't
	take into account (1) that BFD doesn't use the ordinary texinfo
	sectioning commands, and (2) that some users are stuck on very ancient
	versions of makeinfo.

	This patch reverts the change.

	I went through the entire manual using the spacebar, trying to find
	the original problem I reported in the change, but couldn't.  I don't
	know why.  Anyway, all this means is that, with this reversion,
	editing the node structure will be slightly less convenient.

	[gdb/contrib] Require minimal dwz version in cc-with-tweaks.sh
	I usually run target boards cc-with-dwz and cc-with-dwz-m using a dwz build
	from current trunk, but the pathname to the build dir changed and I forgot to
	update my test scripts, so the test scripts reverted to using system dwz,
	version 0.12.

	Consequently, I ran into:
	...
	(gdb) p ZERO^M
	No symbol "ZERO" in current context.^M
	(gdb) FAIL: gdb.base/enumval.exp: p ZERO
	...
	which is due to PR dwz/24468, which was fixed in version 0.13.

	Fix this by minimally requiring dwz version 0.13 in cc-with-tweaks.sh, such
	that this situation is detected and we get instead:
	...

	gas init_stab_section and get_stab_string_offset
	get_stab_string_offset currently creates the stabstr section if not
	already present, in the process keeping a reference to the malloc'd
	section name string.  Really, the name belongs in bfd_alloc'd memory
	or some obstack so that it doesn't show as a memory leak on exit.
	s_stab_generic at least does allocate the name for the stab section on
	an obstack, but doesn't tidy that as well as it could.  Return paths
	after issuing a warning don't release the memory, nor the memory for
	the "string" copy.

	This patch fixes these problems.  s_stab_generic is rearranged so that
	creation of the sections occurs earlier, before any potential uses of
	the note obstack during expression parsing.  That makes it possible to
	always free the section name strings unless used to create new
	sections.  I've also avoided get_absolute_expression_and_terminator
	as I see that function might skip over end-of-line, and lack of a
	--input_line_pointer might have caused the following source line to be
	ignored.  (Other uses of this function in gas are OK.)

	[gdb/symtab] Do more zero-initialization of type::fields
	Now that we've introduced type::{alloc_fields,copy_fields}, the places where
	no zero-initialization of allocated fields is done are easy to spot:
	...
	$ find gdb* -type f | grep -v ChangeLog | xargs grep alloc_fields | grep false
	gdb/coffread.c:  type->alloc_fields (nfields, false);
	gdb/coffread.c:  type->alloc_fields (nsyms, false);
	gdb/stabsread.c:	  ftype->alloc_fields (nsemi, false);
	gdb/gdbtypes.c:  resolved_type->alloc_fields (nfields, false);

	gdb/mdebugread.c:	t->alloc_fields (nfields, false);
	gdb/mdebugread.c:		  ftype->alloc_fields (nparams, false);
	...

	All hits in gdbtypes.c are ok.  There are two hits in the two variants of
	copy_fields, and there's already a comment for the third.

	AFAICT, the other ones are not ok, so fix those by dropping the "false"
	argument.

	[gdb/symtab] Factor out type::{alloc_fields,copy_fields}
	After finding this code in buildsym_compunit::finish_block_internal:
	...
	              ftype->set_fields
	                ((struct field *)
	                 TYPE_ALLOC (ftype, nparams * sizeof (struct field)));
	...
	and fixing PR30810 by using TYPE_ZALLOC, I wondered if there were more
	locations that needed fixing.

	I decided to make things easier to spot by factoring out a new function
	alloc_fields:
	...
	 /* Allocate the fields array of this type, with NFIELDS elements.  If INIT,
	     zero-initialize the allocated memory.  */
	  void
	  type::alloc_fields (unsigned int nfields, bool init = true);
	...
	where:
	- a regular use would be "alloc_fields (nfields)", and
	- an exceptional use that needed no initialization would be
	  "alloc_fields (nfields, false)".

	Pretty soon I discovered that most of the latter cases are due to
	initialization by memcpy, so I added two variants of copy_fields as well.

	After this rewrite there are 8 uses of set_fields left:
	...
	gdb/coffread.c:	  type->set_fields (nullptr);
	gdb/coffread.c:	  type->set_fields (nullptr);
	gdb/coffread.c:	  type->set_fields (nullptr);
	gdb/eval.c:  type->set_fields
	gdb/gdbtypes.c:  type->set_fields (args);
	gdb/gdbtypes.c:  t->set_fields (XRESIZEVEC (struct field, t->fields (),
	gdb/dwarf2/read.c:      type->set_fields (new_fields);
	gdb/dwarf2/read.c:	      sub_type->set_fields (sub_type->fields () + 1);
	...

	These fall into the following categories:
	- set to nullptr (coffread.c),
	- type not owned by objfile or gdbarch (eval.c), and
	- modifying an existing fields array, like adding an element at the end or
	  dropping an element at the start (the rest).

	Tested on x86_64-linux.

	gdbserver: Fix style of struct declarations in i387-fp.cc

2023-08-28  John Baldwin  <jhb@FreeBSD.org>

	gdbserver: Simplify handling of ZMM registers.
	- Reuse num_xmm_registers directly for the count of ZMM0-15 registers
	  as is already done for the YMM registers for AVX rather than using
	  a new variable that is always the same.

	- Replace 3 identical variables for the count of upper ZMM16-31
	  registers with a single variable.  Make use of this to merge
	  various loops working on the ZMM XSAVE region so that all of the
	  handling for the various sub-registers in this region are always
	  handled in a single loop.

	- While here, fix some bugs in i387_cache_to_xsave where if
	  X86_XSTATE_ZMM was set on i386 (e.g. a 32-bit process on a 64-bit
	  kernel), the -1 register nums would wrap around and store the value
	  of GPRs in the XSAVE area.  This should be harmless, but is
	  definitely odd.  Instead, check num_zmm_high_registers directly when
	  checking X86_XSTATE_ZMM and skip the ZMM region handling entirely if
	  the register count is 0.

	x86: Add an x86_xsave_layout structure to handle variable XSAVE layouts.
	The standard layout of the XSAVE extended state area consists of three
	regions.  The first 512 bytes (legacy region) match the layout of the
	FXSAVE instruction including floating point registers, MMX registers,
	and SSE registers.  The next 64 bytes (XSAVE header) contains a header
	with a fixed layout.  The final region (extended region) contains zero
	or more optional state components.  Examples of these include the
	upper 128 bits of YMM registers for AVX.

	These optional state components generally have an
	architecturally-fixed size, but they are not assigned architectural
	offsets in the extended region.  Instead, processors provide
	additional CPUID leafs describing the size and offset of each
	component in the "standard" layout for a given CPU.  (There is also a
	"compact" format which uses an alternate layout, but existing OS's
	currently export the "standard" layout when exporting XSAVE data via
	ptrace() and core dumps.)

	To date, GDB has assumed the layout used on current Intel processors
	for state components in the extended region and hardcoded those
	offsets in the tables in i387-tdep.c and i387-fp.cc.  However, this
	fails on recent AMD processors which use a different layout.
	Specifically, AMD Zen3 and later processors do not leave space for the
	MPX register set in between the AVX and AVX512 register sets.

	To rectify this, add an x86_xsave_layout structure which contains the
	total size of the XSAVE extended state area as well as the offset of
	each known optional state component.

	Subsequent commits will modify XSAVE parsing in both gdb and gdbserver
	to use x86_xsave_layout.

	Simplify definition of GUILE
	This patch sets GUILE to just plain 'guile'.

	In the distant ("devo") past, the top-level build did support building

	For one thing, there are no build dependencies on it, so there's no
	guarantee it would actually be built before the uses.

	This patch also removes the use of "-s" as an option to cgen scheme
	scripts.  With my latest patch upstream, this is no longer needed.

	Use get_frame_address_in_block in print_frame
	The author of 'mold' pointed out that with a certain shared library,
	gdb would fail to find the shared library's name in 'bt'.

	The function in question appeared at the end of the .so's .text
	segment and ended with a call to 'abort'.

	This turned out to be a classic case of calling get_frame_pc when
	get_frame_address_in_block is needed -- the former will be off-by-one
	for purposes of finding the enclosing function or shared library.

	The included test fails without the patch on my system.  However, I

	bfd: correct relocation handling for objcopy COFF -> ELF
	While documented to not be reliable, it is still odd for objcopy to
	silently produce bad output when converting COFF/PE object files to ELF
	ones. The issue there is that relocation addends all are screwed up by
	subtracting the symbol's section offset. In the COFF/PE world, to my
	knowledge, section contents stores the addends alone, not the result of
	symbol value plus addend. Hence the compensation talked about in a
	comment ahead of the sole use site of CALC_ADDEND() may need to account
	for the VMA (which is always zero for object files anyway), but not for
	the symbol value.

	The coff-sh.c adjustment is based upon guessing that behavior there is
	the same. Note also how coff-aarch64.c short-circuits CALC_ADDEND()
	altogether, which may suggest that a much simpler macro might do for the
	COFF_WITH_PE case in the three arch-specific files touched here.

	For (at least) Arm/WinCE this actually results in more appropriate
	objdump output as well, as can be seen in the one testcase which has its
	expectations adjusted (the generated binary doesn't change).

	Rather than special-casing rx-*-* for section30, force use of

	eliminated (some of which had wrong justifications in associated
	comments anyway). Note that section7 and section15 need to be left
	alone: The harness fiddling with section names there didn't help before
	and is getting in the way now. For section12b, section16b, and most of
	the Dwarf tests nothing changes. Interestingly by passing $dump_opts
	the need to xfail section11 for LoongArch and RISC-V also goes away.

	gas/ELF: allow "inheriting" section attributes and type
	While --sectname-subst is nice, it isn't enough to e.g. mimic
	-f{function,data}-sections in assembly code, when such use is to be
	optional (e.g. dependent upon some configuration setting).

	Assign meaning to '+' and '-' as section attribute letters, allowing
	to inherit the prior section's attributes (and possibly type) along
	with adding or removing some. Note that documenting the interaction
	with '?' as undefined is a precautionary measure.

	While touching the function invocation, stop using |= on the result of
	obj_elf_parse_section_letters(): "attr" is firmly zero ahead of the
	call.

	gdb/solib-rocm: Detect SO for unsupported AMDGPU device
	It is possible to debug a process which uses unsupported AMDGPU devices.
	In such scenario, we can still use librocm-dbgapi.so to attach to the
	process and complete the runtime activation sequence.

	However, when listing shared objects loaded on the AMDGPU devices, we
	might list SOs loaded on the unsupported devices.  If such SO is
	seen, one of two things can happen.

	First, if the arch of this device is unknown to BFD,
	'gdbarch_find_by_info (gdbarch_info info)' will return the gdbarch
	matching default_bfd_arch.  As a result,
	rocm_solib_relocate_section_addresses will delegate the relocation
	operation to svr4_so_ops.relocate_section_addresses, but this makes no
	sense: this code object was not loaded by the system loader.

	The second case is if BFD knows the micro-architecture of the device,
	but dbgapi does not support it.  In such case, gdbarch_info_fill will
	successfully identify an amdgcn architecture (bfd_arch_amdgcn).  From
	there, gdbarch_find_by_info calls amdgpu_gdbarch_init which will fail to
	query arch specific details from dbgapi and subsequently fail to
	initialize the gdbarch object.  As a result, gdbarch_find_by_info
	returns nullptr, which will down the line cause some "gdb_assert
	(gdbarch != nullptr)" assertion failures.

	This patch proposes to add a check in rocm_solib_bfd_open to ensure that
	the architecture associated with the code object to open is fully
	supported by both BFD and amd-dbgapi, and error-out otherwise.

	gdb/testsuite: Multiple improvements for gdb.reverse/insn-reverse.exp
	This commits tackles 2 problems in the test
	gdb.reverse/insn-reverse.exp. They are, broadly: flawed logic when an
	unexpected error occurs, and badly formed asm expressions.

	For the first, what happens is that if the inferior stops progressing
	for some reason, the test will emit an UNSUPPORTED and continue testing
	by reversing from the current location and checking all registers for
	every instruction.  However, due to how the outputs are indexed in the
	test, this early exit will cause most of the subsequent tests to be
	de-synced and will emit many unrelated failures.

	This commit changes the UNSUPPORTED for a FAIL, since the test has in
	fact failed to record the execution of the whole function, and
	decrements the recorded instruction count by one so that the indexes are
	in sync once more.

	At the time of committing, this reduces the amount of failures when
	testing with clang-15 from around 150 to 2, and correctly identifies
	where the issue lies.

	The second problem is in how the asm statements in the *-x86.c file
	are written. As an example, let's examine the following line:

	__asm__ volatile ("rdrand %%ebp;" : "=r" (number));

	This statement says that number is being used as the output variable,
	but is not indicating which registers were clobbered so that the
	compiler is able to properly output. GCC decides to just not save
	anything, whereas clang assumes that the output is in %rax, and writes
	it to the variable. This hid the problem that any compiler is not good
	at dealing with asm statements that change the rbp register. It can be
	seen more explicitly by informing gcc that rbp has been clobbered like
	so:

	__asm__ volatile ("rdrand %%ebp;" : "=r" (number) : : "%ebp");

	This statement gets compiled into the following assembly:
	        rdrandl %ebp
	        movl    %eax, -4(%rbp)

	Which is clearly using the incorrect rbp to find the memory location of
	the variable. Since the test only exercises GDB's ability to record the
	register changes, this commit removes the output to memory.

	Finally, correctly informing the compiler of clobbered registers
	makes gcc throw an error that the rsp is no longer usable at the end of
	the function. To avoid that, this commit compresses the 3 asm statements
	that would save, change and reset registers into a single asm statement.

	gdb/testsuite: fix testing gdb.reverse/step-reverse.exp with clang
	When testing using reverse-stepi to fully step through a function, the
	code checks for an infinite loop by seeing if we land on the line that
	contains the return statement multiple times. This assumption only works
	if there is only one instruction associated with that line, which is how
	GCC handles line information, but other compilers may handle it differently.
	Clang-15, for instance, associates 6. Because of this, the inferior used
	to get seriously out of sync with the test expectations, and result in 13
	spurious failures. The same issue occurs with gdb.reverse/step-precsave.exp.

	This commit changes the test so that we check for PC instead of line
	number. The test still only happens when the same line is detected, to
	simplify the resulting log. With this change, no new failures are
	emitted when using clang.

	gdb/testsuite: fix gdb.reverse/solib-*.exp tests when using clang
	The tests gdb.reverse/solib-precsave.exp and solib-reverse.exp have the
	assumption that line tables will have an entry for the closing } in a
	function. Not all compiles do this, one example being clang. To fix
	this, this commit changes the function in shr2.c to have multiple lines,
	and the test to accept either line as a correct step location.

	To properly re-sync the inferiors, the function repeat_cmd_until had to
	be slightly changed to work with empty "current locations", so that we
	are able to step through multiple lines.

	This also changes the annotations used to determine the breakpoint
	locations in solib-reverse.c, adding a simple variable assignment right
	before the return statement. This way GDB will not set a breakpoint in
	the closing } line.

	sim: or1k: Eliminate dangerous RWX load segments
	This fixes test failures caused by the new linker warning which report:

	  ./ld/ld-new: warning: load.S.x has a LOAD segment with RWX permissions

	Fix this by splitting the linker MEMORY into ram and rom to avoid
	generating RWX sections.  This required tests to be adjusted to fix
	issues with the move.  Namely:

	  - fpu tests: were incorrectly using l.ori with ha(anchor) which now
	    that we pushed the anchor up in memory it exposes the bug.  Update
	    to used the correct l.movhi instruction instead.
	  - adrp test: the test reports ram offset addresses, now that we have
	    moved memory layout around a bit I adjusted the test output.  Some
	    padding is added before pi to show that the actual address of pi and
	    the adrp page offset are not the same.

	The problem is that the loop around GetConsoleProcessList looped
	forever, because there were exactly 10 processes to return.
	GetConsoleProcessList's documentation says:

	  If the buffer is too small to hold all the valid process identifiers,
	  the return value is the required number of array elements. The
	  function will have stored no identifiers in the buffer. In this
	  situation, use the return value to allocate a buffer that is large
	  enough to store the entire list and call the function again.

	In this case, the buffer wasn't too small, it was exactly the right
	size, so we should have broken out of the loop.  We didn't due to a
	"<" check that should have been "<=".  That is fixed by this patch.

	gdb: MI stopped events when unwindonsignal is on
	This recent commit:

	  commit b1c0ab20809a502b2d2224fecb0dca3ada2e9b22
	  Date:   Wed Jul 12 21:56:50 2023 +0100

	      gdb: avoid double stop after failed breakpoint condition check

	Addressed a problem where two MI stopped events would be reported if a
	breakpoint condition failed due to a signal, this commit was a
	replacement for this commit:

	  commit 2e411b8c68eb2b035b31d5b00d940d4be1a0928b
	  Date:   Fri Oct 14 14:53:15 2022 +0100

	      gdb: don't always print breakpoint location after failed condition check

	which solved the two stop problem, but only for the CLI.  Before both
	of these commits, if a b/p condition failed due to a signal then the
	user would see two stops reported, the first at the location where the
	signal occurred, and the second at the location of the breakpoint.

	By default GDB remains at the location where the signal occurred, so
	the second reported stop can be confusing, this is the problem that
	commit 2e411b8c68eb tried to solve (for the CLI) and b1c0ab20809a
	extended also address the issue for MI too.

	However, while working on another patch I realised that there was a
	problem with GDB after the above commits.  Neither of the above
	commits considered 'set unwindonsignal on'.  With this setting on,
	when an inferior function call fails with a signal GDB will unwind the
	stack back to the location where the inferior function call started.
	In the b/p case we're looking at, the stop should be reported at the
	location of the breakpoint, not at the location where the signal
	occurred, and this isn't what happens.

	This commit fixes this by ensuring that when unwindonsignal is 'on',
	GDB reports a single stop event at the location of the breakpoint,
	this fixes things for both CLI and MI.

	The function call_thread_fsm::should_notify_stop is called when the
	inferior function call completes and GDB is figuring out if the user
	should be notified about this stop event by calling normal_stop from
	fetch_inferior_event in infrun.c.  If normal_stop is called, then this
	notification will be for the location where the inferior call stopped,
	which will be the location at which the signal occurred.

	Prior to this commit, the only time that normal_stop was not called,
	was if the inferior function call completed successfully, this was
	controlled by ::should_notify_stop, which only turns false when the
	inferior function call has completed successfully.

	In this commit I have extended the logic in ::should_notify_stop.  Now
	there are three cases in which ::should_notify_stop will return false,
	and we will not announce the first stop (by calling normal_stop).
	These three reasons are:

	  1. If the inferior function call completes successfully, this is
	  unchanged behaviour,

	  2. If the inferior function call stopped due to a signal and 'set
	  unwindonsignal on' is in effect, and

	  3. If the inferior function call stopped due to an uncaught C++
	  exception, and 'set unwind-on-terminating-exception on' is in
	  effect.

	However, if we don't call normal_stop then we need to call
	async_enable_stdin in call_thread_fsm::should_stop.  Prior to this
	commit this was only done for the case where the inferior function
	call completed successfully.

	In this commit I now call ::should_notify_stop and use this to
	determine if we need to call async_enable_stdin.  With this done we
	now call async_enable_stdin for each of the three cases listed above,
	which means that GDB will exit wait_sync_command_done correctly (see
	run_inferior_call in infcall.c).

	With these two changes the problem is mostly resolved.  However, the
	solution isn't ideal, we've still lost some information.

	Here is how GDB 13.1 behaves, this is before commits b1c0ab20809a and
	2e411b8c68eb:

	  $ gdb -q /tmp/mi-condbreak-fail \
	        -ex 'set unwindonsignal on' \
	        -ex 'break 30 if (cond_fail())' \
	        -ex 'run'
	  Reading symbols from /tmp/mi-condbreak-fail...
	  Breakpoint 1 at 0x40111e: file /tmp/mi-condbreak-fail.c, line 30.
	  Starting program: /tmp/mi-condbreak-fail

	  Program received signal SIGSEGV, Segmentation fault.
	  0x0000000000401116 in cond_fail () at /tmp/mi-condbreak-fail.c:24
	  24	  return *p;			/* Crash here.  */
	  Error in testing breakpoint condition:
	  The program being debugged was signaled while in a function called from GDB.
	  GDB has restored the context to what it was before the call.
	  To change this behavior use "set unwindonsignal off".
	  Evaluation of the expression containing the function
	  (cond_fail) will be abandoned.

	  Breakpoint 1, foo () at /tmp/mi-condbreak-fail.c:30
	  30	  global_counter += 1;		/* Set breakpoint here.  */
	  (gdb)

	In this state we see two stop notifications, the first is where the
	signal occurred, while the second is where the breakpoint is located.
	As GDB has unwound the stack (thanks to unwindonsignal) the second
	stop notification reflects where the inferior is actually located.

	Then after commits b1c0ab20809a and 2e411b8c68eb the behaviour changed
	to this:

	  $ gdb -q /tmp/mi-condbreak-fail \
	        -ex 'set unwindonsignal on' \
		-ex 'break 30 if (cond_fail())' \
		-ex 'run'
	  Reading symbols from /tmp/mi-condbreak-fail...
	  Breakpoint 1 at 0x40111e: file /tmp/mi-condbreak-fail.c, line 30.
	  Starting program: /tmp/mi-condbreak-fail

	  Program received signal SIGSEGV, Segmentation fault.
	  0x0000000000401116 in cond_fail () at /tmp/mi-condbreak-fail.c:24
	  24	  return *p;			/* Crash here.  */
	  Error in testing condition for breakpoint 1:
	  The program being debugged was signaled while in a function called from GDB.
	  GDB has restored the context to what it was before the call.
	  To change this behavior use "set unwindonsignal off".
	  Evaluation of the expression containing the function
	  (cond_fail) will be abandoned.
	  (gdb) bt 1
	  #0  foo () at /tmp/mi-condbreak-fail.c:30
	  (More stack frames follow...)
	  (gdb)

	This is the broken state.  GDB is reports the SIGSEGV location, but
	not the unwound breakpoint location.  The final 'bt 1' shows that the
	inferior is not located in cond_fail, which is the only location GDB
	reported, so this is clearly wrong.

	After implementing the fixes described above we now get this
	behaviour:

	  $ gdb -q /tmp/mi-condbreak-fail \
	        -ex 'set unwindonsignal on' \
	        -ex 'break 30 if (cond_fail())' \
	        -ex 'run'
	  Reading symbols from /tmp/mi-condbreak-fail...
	  Breakpoint 1 at 0x40111e: file /tmp/mi-condbreak-fail.c, line 30.
	  Starting program: /tmp/mi-condbreak-fail
	  Error in testing breakpoint condition for breakpoint 1:
	  The program being debugged was signaled while in a function called from GDB.
	  GDB has restored the context to what it was before the call.
	  To change this behavior use "set unwindonsignal off".
	  Evaluation of the expression containing the function
	  (cond_fail) will be abandoned.

	  Breakpoint 1, foo () at /tmp/mi-condbreak-fail.c:30
	  30	  global_counter += 1;		/* Set breakpoint here.  */
	  (gdb)

	This is better.  GDB now reports a single stop at the location of the
	breakpoint, which is where the inferior is actually located.  However,
	by removing the first stop notification we have lost some potentially
	useful information about which signal caused the inferior to stop.

	To address this I've reworked the message that is printed to include
	the signal information.  GDB now reports this:

	  $ gdb -q /tmp/mi-condbreak-fail \
	        -ex 'set unwindonsignal on' \
	        -ex 'break 30 if (cond_fail())' \
	        -ex 'run'
	  Reading symbols from /tmp/mi-condbreak-fail...
	  Breakpoint 1 at 0x40111e: file /tmp/mi-condbreak-fail.c, line 30.
	  Starting program: /tmp/mi-condbreak-fail
	  Error in testing condition for breakpoint 1:
	  The program being debugged received signal SIGSEGV, Segmentation fault
	  while in a function called from GDB.  GDB has restored the context
	  to what it was before the call.  To change this behavior use
	  "set unwindonsignal off".  Evaluation of the expression containing
	  the function (cond_fail) will be abandoned.

	  Breakpoint 1, foo () at /tmp/mi-condbreak-fail.c:30
	  30	  global_counter += 1;		/* Set breakpoint here.  */
	  (gdb)

	This is better, the user now sees a single stop notification at the
	correct location, and the error message describes which signal caused
	the inferior function call to stop.

	However, we have lost the information about where the signal
	occurred.  I did consider trying to include this information in the
	error message, but, in the end, I opted not too.  I wasn't sure it was
	worth the effort.  If the user has selected to unwind on signal, then
	surely this implies they maybe aren't interested in debugging failed
	inferior calls, so, hopefully, just knowing the signal name will be
	enough.  I figure we can always add this information in later if
	there's a demand for it.

	gdb/testsuite: add mi_info_frame helper proc (and use it)
	New helper proc mi_info_frame which takes care of running the MI
	-stack-info-frame command and matching its output.

	Like the breakpoint helper procs, this new proc takes a name/value
	argument list and uses this to build the expected result regexp.  This
	means that we can now write something like:

	  mi_info_frame "test name here" \
	    -level 0 -func name -line 123

	Instead of the current equivalent:

	  mi_gdb_test "235-stack-info-frame" \
	    "235\\^done,frame=\{level=\"0\",addr=\"$hex\",func=\"name\",file=\".*\",fullname=\".*\",line=\"123\",arch=\".*\"\}" \
	    "test name here"

	There's also a helper proc mi_make_info_frame_regexp which is
	responsible for building the 'frame={...}' part of the pattern.

	I've update the two existing tests that use -stack-info-frame and
	expect the command to succeed.  There is another test that runs
	-stack-info-frame and expects the command to fail -- the helper proc
	doesn't help with this case, so that test is not changed.

	This commit fixes this by moving the thread exit printing to common
	code instead, triggered from within delete_thread (or rather,
	set_thread_exited).

	There's one wrinkle, though.  While most targest want to print:

	 [Thread ... exited]

	the Windows target wants to print:

	 [Thread ... exited with code <exit_code>]

	... and sometimes wants to suppress the notification for the main
	thread.  To address that, this commits adds a delete_thread_with_code
	function, only used by that target (so far).

	This fix was originally posted as part of a larger series:

	  https://inbox.sourceware.org/gdb-patches/20221212203101.1034916-1-pedro@palves.net/

	But didn't really need to be part of that series.  In order to get

	gdb: remove the silent parameter from exit_inferior_1 and cleanup
	After the previous commit, exit_inferior_1 no longer makes use of the
	silent parameter.  This commit removes this parameter and cleans up
	the callers.

	After doing this exit_inferior_1, exit_inferior, and
	exit_inferior_silent are all equivalent, so rename exit_inferior_1 to
	exit_inferior and delete exit_inferior_silent, update all the callers.

	Also I spotted the declaration exit_inferior_num_silent in inferior.h,
	but this function is not defined anywhere, so I deleted the
	declaration.

	There should be no user visible changes after this commit.

	gdb: make inferior::clear_thread_list always silent
	After this commit:

	  commit a78ef8757418105c35685c5d82b9fdf79459321b
	  Date:   Wed Jun 22 18:10:00 2022 +0100

	      Always emit =thread-exited notifications, even if silent

	The function mi_interp::on_thread_exited (or mi_thread_exit as the
	function was called back then) no longer makes use of the "silent"
	parameter.

	As a result there is no difference between inferior::clear_thread_list
	with silent true or false, because:

	  - None of the interpreter ::on_thread_exited functions rely on the
	    silent parameter, and

	  - None of GDB's thread_exit observers rely on the silent parameter
	  either.

	This commit removes the silent parameter from
	inferior::clear_thread_list, and makes the function always silent.

	This commit was originally part of a larger series:

	  https://inbox.sourceware.org/gdb-patches/20221212203101.1034916-1-pedro@palves.net/

	But didn't really need to be part of that series.  I had an interest
	in seeing this patch merged:

	  https://inbox.sourceware.org/gdb-patches/20221212203101.1034916-31-pedro@palves.net/

	Which also didn't really need to be part of the larger series, but
	does depend, at least a little, on this commit.  In order to get the
	fix I'm interested in merged quicker, I (Andrew Burgess) have rebased
	this commit outside of the original series.  Any bugs introduced while
	splitting this patch out and rebasing, are entirely my own.

	gdb: remove mi_parse::make functions
	Remove the static mi_parse::make functions, and instead use the
	mi_parse constructor.

	This is a partial revert of the commit:

	  commit fde3f93adb50c9937cd2e1c93561aea2fd167156
	  Date:   Mon Mar 20 10:56:55 2023 -0600

	      Introduce "static constructor" for mi_parse

	which introduced the mi_parse::make functions, though after discussion
	on the list the reasons for seem to have been lost[1].  Given there
	are no test regressions when moving back to using the constructors, I
	propose we should do that for now.

	There should be no user visible changes after this commit.

	gdb: add gdb::make_unique function
	While GDB is still C++11, lets add a gdb::make_unique template
	function that can be used to create std::unique_ptr objects, just like
	the C++14 std::make_unique.

	If GDB is being compiled with a C++14 compiler then the new
	gdb::make_unique function will delegate to the std::make_unique.  I
	checked with gcc, and at -O1 and above gdb::make_unique will be
	optimised away completely in this case.

	If C++14 (or later) becomes our minimum, then it will be easy enough
	to go through the code and replace gdb::make_unique with
	std::make_unique later on.

	I've make use of this function in all the places I think this can
	easily be used, though I'm sure I've probably missed some.

	Should be no user visible changes after this commit.

	gdb/testsuite: improve MI support for inferior specific breakpoints
	In this commit:

	  commit b080fe54fb3414b488b8ef323c6c50def061f918
	  Date:   Tue Nov 8 12:32:51 2022 +0000

	      gdb: add inferior-specific breakpoints

	limited support was added in lib/mi-support.exp to help with testing
	of inferior specific breakpoints.

	Though the changes that were added were not wrong, while working on a
	later patch, I realised that I had added the support in the wrong
	place -- I only added support to mi_make_breakpoint_multi, when really
	I should have added the support to mi_make_breakpoint_1, which is used
	by all of the MI procs that create breakpoints.

	This commit moves the support to mi_make_breakpoint_1, and updates all
	the procs that use mi_make_breakpoint_1 to accept, and then pass
	through, and (optional) inferior argument.  This will make it much
	easier to write MI tests for inferior specific breakpoints.

	There's no change in what is tested after this commit.

	gdb: add missing notify_breakpoint_modified call
	The commit:

	  commit b080fe54fb3414b488b8ef323c6c50def061f918
	  Date:   Tue Nov 8 12:32:51 2022 +0000

	      gdb: add inferior-specific breakpoints

	introduced a bug in the function breakpoint_set_inferior. The above
	commit includes this line:

	  gdb::observers::breakpoint_modified.notify (b);

	when it should have instead used this line:

	  notify_breakpoint_modified (b);

	The change to use notify_breakpoint_modified was introduced to GDB
	after commit b080fe54fb34 was written, but before it was merged, and I
	failed to update this part of the code during the rebase.

	The consequence of this error is that the MI interpreter will not emit
	breakpoint-modified notifications when breakpoint_set_inferior is
	called.

	In this commit I update the code to call notify_breakpoint_modified,
	and add a test that checks the MI events are being emitted correctly
	in this case.

	kvx bfd signed calculations and _bfd_kvx_elf_resolve_relocation
	It is generally a good idea to avoid signed arithmetic on values
	extracted from object files, to avoid ubsan warnings on overflow.
	This patch replaces some uses of bfd_signed_vma in the kvx backend
	with bfd_vma, and removes _bfd_kvx_elf_resolve_relocation, a
	do-nothing function.  In the process of making this patch I noticed
	some dead code in the GOT entry handling, setting value to
	got_entry_addr but using "off" in the _bfd_final_link_relocate call.
	Since kvx_calculate_got_entry_vma also returns the GOT offset, I

	there.

	[gdb/build] Work around cgen odr violations
	When building gdb with -flto -O2, I run into:
	...
	opcodes/mep-desc.h:250:14: warning: type 'cgen_operand_type' violates the \
	  C++ One Definition Rule [-Wodr]
	 typedef enum cgen_operand_type {
	              ^
	opcodes/or1k-desc.h:624:14: note: an enum with different value name is \
	  defined in another translation unit
	 typedef enum cgen_operand_type {
	              ^
	opcodes/mep-desc.h:212:14: warning: type 'cgen_hw_type' violates the C++ One \
	  Definition Rule [-Wodr]
	 typedef enum cgen_hw_type {
	              ^

	  defined in another translation unit
	 typedef enum cgen_hw_type {
	              ^
	...

	Fix this by making the conflicting type names unique, adding a target-specific
	prefix using a define before the include:
	...
	 #define cgen_operand_type <target-name>_cgen_operand_type
	 #define cgen_hw_type  <target-name>_cgen_hw_type
	 #include "opcodes/<target-name>-desc.h"
	...
	and move those defines into a new file cgen-remap.h, similar to how that's
	done for yacc in yy-remap.h.

	Likewise for targets frv and lm32, the two other targets that include
	opcodes/<target-name>-desc.h.

	Likewise for more cgen symbols that I got the same warning for when using
	-flto-partition=one.

	A PR has been filed to take care of this in the opcodes dir instead (PR30758).

	aarch64: Improve naming conventions for A and R-profile architecture
	Historically, flags and variables relating to architectural revisions
	for the A-profile architecture omitted the trailing `A' such that, for
	example, assembling for `-march=armv8.4-a' set the `AARCH64_ARCH_V8_4'
	flag in the assembler.

	This leads to some ambiguity, since Binutils also targets the
	R-profile Arm architecture.  Therefore, it seems prudent to have
	everything associated with the A-profile cores end in `A' and likewise
	`R' for the R-profile.  Referring back to the example above, the flag
	set for `-march=armv8.4-a' is better characterized if labeled
	`AARCH64_ARCH_V8_4A'.

	The only exception to the rule of appending `A' to variables is found
	in the handling of the `AARCH64_FEATURE_V8' macro, as it is the
	baseline from which ALL processors derive and should therefore be left
	unchanged.

	In reflecting the `ARM' architectural nomenclature choices, where we
	have `ARM_ARCH_V8A' and `ARM_ARCH_V8R', the choice is made to not have
	an underscore separating the numerical revision number and the
	A/R-profile indicator suffix.  This has meant that renaming of
	R-profile related flags and variables was warranted, thus going from
	`.*_[vV]8_[rR]' to `.*_[vV]8[rR]'.

	Finally, this is more in line with conventions within GCC and adds consistency
	across the toolchain.

	kvx_dis_init

	I've chosen the default mach to be bfd_mach_kv3_1, the default in

	aarch64/sme2: Teach binutils/BFD about the NT_ARM_ZT register set
	The Scalable Matrix Extension v2 (SME2) defines a new register, ZT0, that
	the Linux Kernel handles through a new NT_ARM_ZT register set.

	Teach binutils/BFD about it so that gdb can make use of it for reading
	and writing core files.  This also enables readelf/objdump to show the
	correct identification for the NT_ARM_ZT register set.

	Validated under Fast Models.

	bfd_close_all_done bug and bfd_last_cache
	bfd_close ought to always call iovec->bclose so that cache_bclose is
	called.  If not, bfd_last_cache will be left pointing at freed memory.
	This bug was found by oss-fuzz with the trigger being an old bug in
	the ia64-vms support.  Given a file of the "wrong" size,
	elf64_vms_close_and_cleanup attempted to extend it, leading to an
	error since the file was opened read-only by nm.  nm bad_file bad_file
	then hit the use-after-free when opening the second file.

	Placate -Wmissing-declarations in sim/cris
	I get a couple of -Wmissing-declarations errors when building the sim.
	This happens because an earlier patch added the declarations to a
	cgen-generated header, but the recent re-generation then removed them.

	This patch fixes the build by adding declarations just before the
	definition.  This is normally not best practice, but in this
	particular situation it at leat un-breaks the build.

	sim --enable-cgen-maint
	I had reason yesterday to want to regenerate configury files which I
	do with --enable-maintainer-mode, and added --enable-cgen-maint
	accidentally.  The first problem I hit is that sim looks for cgen in a
	different directory by default than opcodes, and I had my source
	layout set up for opcodes rather than sim.  Fix that by making both
	use ../cgen first, then ../../cgen relative to sim/ and opcodes/.  The
	next problem was that various sim local.mk files expected generated
	sources in the build dir rather than the source dir.  Fix that by
	adding $(srcdir) to paths.  Finally, the generated iq2000 files had a
	compile error, fixed by the cpu/iq2000.cpu patch.

	Fix off-by-one in call to vector::reserve
	While looking at a bug, I noticed what I think is an off-by-one
	mistake in a call to vector::reserve.  This code:

	      new_args.reserve (args.size ());
	      new_args.push_back
		(value_from_pointer (lookup_pointer_type (values_type), struct_addr));
	      new_args.insert (new_args.end (), args.begin (), args.end ());

	... reserves 'size()' entries, but then proceeds to push one extra
	one.

	This shouldn't have any really bad effects, as insert will grow the
	vector.  Still, it seems better to use the correct size if we're going
	to bother calling reserve.

	gdb: add inferior-specific breakpoints
	This commit extends the breakpoint mechanism to allow for inferior
	specific breakpoints (but not watchpoints in this commit).

	As GDB gains better support for multiple connections, and so for
	running multiple (possibly unrelated) inferiors, then it is not hard
	to imagine that a user might wish to create breakpoints that apply to
	any thread in a single inferior.  To achieve this currently, the user
	would need to create a condition possibly making use of the $_inferior
	convenience variable, which, though functional, isn't the most user
	friendly.

	This commit adds a new 'inferior' keyword that allows for the creation
	of inferior specific breakpoints.

	Inferior specific breakpoints are automatically deleted when the
	associated inferior is removed from GDB, this is similar to how
	thread-specific breakpoints are deleted when the associated thread is
	deleted.

	Watchpoints are already per-program-space, which in most cases mean
	watchpoints are already inferior specific.  There is a small window
	where inferior-specific watchpoints might make sense, which is after a
	vfork, when two processes are sharing the same address space.
	However, I'm leaving that as an exercise for another day.  For now,
	attempting to use the inferior keyword with a watchpoint will give an
	error, like this:

	  (gdb) watch a8 inferior 1
	  Cannot use 'inferior' keyword with watchpoints

	A final note on the implementation: currently, inferior specific
	breakpoints, like thread-specific breakpoints, are inserted into every
	inferior, GDB then checks once the inferior stops if we are in the
	correct thread or inferior, and resumes automatically if we stopped in
	the wrong thread/inferior.

	An obvious optimisation here is to only insert breakpoint locations
	into the specific program space (which mostly means inferior) that
	contains either the inferior or thread we are interested in.  This
	would reduce the number times GDB has to stop and then resume again in
	a multi-inferior setup.

	I have a series on the mailing list[1] that implements this
	optimisation for thread-specific breakpoints.  Once this series has
	landed I'll update that series to also handle inferior specific
	breakpoints in the same way.  For now, inferior specific breakpoints
	are just slightly less optimal, but this is no different to
	thread-specific breakpoints in a multi-inferior debug session, so I
	don't see this as a huge problem.

	bpf: gas: consolidate handling of immediate overflows
	This commit changes the BPF GAS port in order to handle immediate
	overflows the same way than the clang BPF assembler:

	- For an immediate field of N bits, any written number (positive or
	  negative) whose two's complement encoding fit in N its is accepted.
	  This means that -2 is the same than 0xffffffe.  It is up to the
	  instructions to decide how to interpret the encoded value.

	- Immediate fields in jump instructions are no longer relaxed.
	  Relaxing to jump instructions with wider range is only performed
	  when expressions are involved.

	- The manual is updated to document this, and testsuite adapted
	  accordingly.

	Tested in x86_64-linux-gnu host, bpf-unknown-none target.

	[gdb/symtab] Handle self-reference DIE
	While working on a dwarf assembly test-case I accidentally created the

	    <bf>   DW_AT_name        : c1
	    <c2>   DW_AT_specification: <0xbe>
	...
	and noticed gdb segfaulting during cooked index creating due to running out of
	stack.  This is a regression from gdb-12, where gdb just hung.

	Fix this by inhibiting the scan_attributes self-recursion for self-references.

	The same test-case with -readnow makes gdb hang, so also fix this in
	dwarf2_attr and follow_die_ref.

	Note that this doesn't fix the same problems for the more complicated case of:
	...
	 <1><be>: Abbrev Number: 3 (DW_TAG_class_type)
	    <bf>   DW_AT_name        : c1

	Fix obvious bug in aggregate expression
	I found an obvious bug in Ada aggregate expression handling:

		  if (vvo != nullptr)
	 	    error (_("Invalid record component association."));
	 	  name = vvo->get_symbol ()->natural_name ();

	Here the code errors when vvo is not null -- and then proceeds to use
	vvo.

	This hasn't caused a crash because, I believe, there's currently no
	way to reach this code in the null case.  However, I'm not really
	willing to assert this...

	Fixing this shows another bug, which is that due to the way the parser
	works, a field name in an aggregate expression might erroneously be
	fully qualified if some global variable with the same base name
	exists.

	The included test case triggers both bugs.  Note that the test
	includes a confounding case for array aggregates as well, but as these
	are harder to fix, I've left it as kfail.

	As this is Ada-specific, and has already been tested internally at
	AdaCore, I am checking it in.

	gdb/testsuite: fix race condition in gdb.python/py-thread-exited.exp
	I ran into a test failure on gdb.python/py-thread-exited.c.  The test
	creates two threads and then catches the thread exits in Python.  The
	test expects the threads to exit in a specific order.

	As the test is currently written, it is _likely_, but not guaranteed,
	that the threads will exit in the same order they are created, which
	is what the test expects.

	When running on a loaded system I ran into a case where the threads
	exited in the reverse creation order, which caused the test to fail.

	I could fix this by having the .exp file not care about the thread
	order, or by changing the C file to force the order. I chose the
	later, and added a pthread_barrier_t to ensure the threads exit in the
	correct order.

	There should be no change in what is tested after this commit.

	      gdb: don't resume vfork parent while child is still running

	the test gdb.base/vfork-follow-parent.exp now has some failures when
	run with the native-gdbserver or native-extended-gdbserver boards:

	  FAIL: gdb.base/vfork-follow-parent.exp: resolution_method=schedule-multiple: continue to end of inferior 2 (timeout)
	  FAIL: gdb.base/vfork-follow-parent.exp: resolution_method=schedule-multiple: inferior 1 (timeout)
	  FAIL: gdb.base/vfork-follow-parent.exp: resolution_method=schedule-multiple: print unblock_parent = 1 (timeout)
	  FAIL: gdb.base/vfork-follow-parent.exp: resolution_method=schedule-multiple: continue to break_parent (timeout)

	The reason that these failures don't show up when run on the standard
	unix board is that the test is only run in the default operating mode,
	so for Linux this will be all-stop on top of non-stop.

	If we adjust the test script so that it runs in the default mode and
	with target-non-stop turned off, then we see the same failures on the
	unix board.  This commit includes this change.

	The way that the test is written means that it is not (currently)
	possible to turn on non-stop mode and have the test still work, so
	this commit does not do that.

	I have also updated the test script so that the vfork child performs
	an exec as well as the current exit.  Exec and exit are the two ways
	in which a vfork child can release the vfork parent, so testing both
	of these cases is useful I think.

	In this test the inferior performs a vfork and the vfork-child
	immediately exits.  The vfork-parent will wait for the vfork-child and
	then blocks waiting for gdb.  Once gdb has released the vfork-parent,
	the vfork-parent also exits.

	In the test that fails, GDB sets 'detach-on-fork off' and then runs to
	the vfork.  At this point the test tries to just "continue", but this
	fails as the vfork-parent is still selected, and the parent can't
	continue until the vfork-child completes.  As the vfork-child is
	stopped by GDB the parent will never stop once resumed, so GDB refuses
	to resume it.

	The test script then sets 'schedule-multiple on' and once again
	continues.  This time GDB, in theory, resumes both the parent and the
	child, the parent will be held blocked by the kernel, but the child
	will run until it exits, and which point GDB stops again, this time
	with inferior 2, the newly exited vfork-child, selected.

	What happens after this in the test script is irrelevant as far as
	this failure is concerned.

	To understand why the test started failing we should consider the
	behaviour of four different cases:

	  1. All-stop-on-non-stop before commit b1e0126ec56e,

	  2. All-stop-on-non-stop after commit b1e0126ec56e,

	  3. All-stop-on-all-stop before commit b1e0126ec56e, and

	  4. All-stop-on-all-stop after commit b1e0126ec56e.

	Only case #4 is failing after commit b1e0126ec56e, but I think the
	other cases are interesting because, (a) they inform how we might fix
	the regression, and (b) it turns out the behaviour of #2 changed too
	with the commit, but the change was harmless.

	For #1 All-stop-on-non-stop before commit b1e0126ec56e, what happens
	is:

	  1. GDB calls proceed with the vfork-parent selected, as schedule
	     multiple is on user_visible_resume_ptid returns -1 (everything)
	     as the resume_ptid (see proceed function),

	  2. As this is all-stop-on-non-stop, every thread is resumed
	    individually, so GDB tries to resume both the vfork-parent and the
	    vfork-child, both of which succeed,

	  3. The vfork-parent is held stopped by the kernel,

	  4. The vfork-child completes (exits) at which point the GDB sees the
	     EXITED event for the vfork-child and the VFORK_DONE event for the
	     vfork-parent,

	  5. At this point we might take two paths depending on which event
	     GDB handles first, if GDB handles the VFORK_DONE first then:

	     (a) As GDB is controlling both parent and child the VFORK_DONE is
	         ignored (see handle_vfork_done), the vfork-parent will be
		 resumed,

	     (b) GDB processes the EXITED event, selects the (now defunct)
	         vfork-child, and stops, returning control to the user.

	     Alternatively, if GDB selects the EXITED event first then:

	     (c) GDB processes the EXITED event, selects the (now defunct)
	         vfork-child, and stops, returning control to the user.

	     (d) At some future time the user resumes the vfork-parent, at
	         which point the VFORK_DONE is reported to GDB, however, GDB
		 is ignoring the VFORK_DONE (see handle_vfork_done), so the
		 parent is resumed.

	For case #2, all-stop-on-non-stop after commit b1e0126ec56e, the
	important difference is in step (2) above, now, instead of resuming
	both the vfork-parent and the vfork-child, only the vfork-child is
	resumed.  As such, when we get to step (5), only a single event, the
	EXITED event is reported.

	GDB handles the EXITED just as in (5)(c), then, later, when the user
	resumes the vfork-parent, the VFORKED_DONE is immediately delivered
	from the kernel, but this is ignored just as in (5)(d), and so,
	though the pattern of when the vfork-parent is resumed changes, the
	overall pattern of which events are reported and when, doesn't
	actually change.  In fact, by not resuming the vfork-parent, the order
	of events (in this test) is now deterministic, which (maybe?) is a
	good thing.

	If we now consider case #3, all-stop-on-all-stop before commit
	b1e0126ec56e, then what happens is:

	  1. GDB calls proceed with the vfork-parent selected, as schedule
	     multiple is on user_visible_resume_ptid returns -1 (everything)
	     as the resume_ptid (see proceed function),

	  2. As this is all-stop-on-all-stop, the resume is passed down to the
	     linux-nat target, the vfork-parent is the event thread, while the
	     vfork-child is a sibling of the event thread,

	  3. In linux_nat_target::resume, GDB calls linux_nat_resume_callback
	     for all threads, this causes the vfork-child to be resumed.  Then
	     in linux_nat_target::resume, the event thread, the vfork-parent,
	     is also resumed.

	  4. The vfork-parent is held stopped by the kernel,

	  5. The vfork-child completes (exits) at which point the GDB sees the
	     EXITED event for the vfork-child and the VFORK_DONE event for the
	     vfork-parent,

	  6. We are now in a situation identical to step (5) as for
	     all-stop-on-non-stop above, GDB selects one of the events to
	     handle, and whichever we select the user sees the correct
	     behaviour.

	And so, finally, we can consider #4, all-stop-on-all-stop after commit
	b1e0126ec56e, this is the case that started failing.

	We start out just like above, in proceed, the resume_ptid is
	-1 (resume everything), due to schedule multiple being on.  And just
	like above, due to the target being all-stop, we call
	proceed_resume_thread_checked just once, for the current thread,
	which, remember, is the vfork-parent thread.

	The change in commit b1e0126ec56e was to avoid resuming a vfork-parent
	thread, read the commit message for the justification for this change.

	However, this means that GDB now rejects resuming the vfork-parent in
	this case, which means that nothing gets resumed!  Obviously, if
	nothing resumes, then nothing will ever stop, and so GDB appears to
	hang.

	I considered a couple of solutions which, in the end, I didn't go
	with, these were:

	  1. Move the vfork-parent check out of proceed_resume_thread_checked,
	     and place it in proceed, but only on the all-stop-on-non-stop
	     path, this should still address the issue seen in b1e0126ec56e,
	     but would avoid the issue seen here.  I rejected this just
	     because it didn't feel great to split the checks that exist in
	     proceed_resume_thread_checked like this,

	  2. Extend the condition in proceed_resume_thread_checked by adding a
	     target_is_non_stop_p check.  This would have the same effect as
	     idea 1, but leaves all the checks in the same place, which I
	     think would be better, but this still just didn't feel right to
	     me, and so,

	What I noticed was that for the all-stop-on-non-stop, after commit
	b1e0126ec56e, we only resumed the vfork-child, and this seems fine.
	The vfork-parent isn't going to run anyway (the kernel will hold it
	back), so if feels like we there's no harm in just waiting for the
	child to complete, and then resuming the parent.

	So then I started looking at follow_fork, which is called from the top
	of proceed.  This function already has the task of switching between
	the parent and child based on which the user wishes to follow.  So, I
	wondered, could we use this to switch to the vfork-child in the case
	that we are attached to both?

	Turns out this is pretty simple to do.

	Having done that, now the process is for all-stop-on-all-stop after
	commit b1e0126ec56e, and with this new fix is:

	  1. GDB calls proceed with the vfork-parent selected, but,

	  2. In follow_fork, and follow_fork_inferior, GDB switches the
	     selected thread to be that of the vfork-child,

	  3. Back in proceed user_visible_resume_ptid returns -1 (everything)
	     as the resume_ptid still, but now,

	  4. When GDB calls proceed_resume_thread_checked, the vfork-child is
	     the current selected thread, this is not a vfork-parent, and so
	     GDB allows the proceed to continue to the linux-nat target,

	  5. In linux_nat_target::resume, GDB calls linux_nat_resume_callback
	     for all threads, this does not resume the vfork-parent (because
	     it is a vfork-parent), and then the vfork-child is resumed as
	     this is the event thread,

	At this point we are back in the same situation as for
	all-stop-on-non-stop after commit b1e0126ec56e, that is, the
	vfork-child is resumed, while the vfork-parent is held stopped by
	GDB.

	Eventually the vfork-child will exit or exec, at which point the
	vfork-parent will be resumed.

	In this example, jump fails because the debugger finds two different
	locations, one for each inferior.

	Solution is to limit the search to the current program space.

	This is done by having the jump_command function use
	decode_line_with_current_source rather than
	decode_line_with_last_displayed, which makes sense,
	the *_current_source function always looks up a location based on the
	current thread's location -- if a user is asking the current thread to
	jump, then surely their destination should be relative to where the
	current thread is located.

	Then, inside decode_line_with_current_source, the call to
	decode_line_1 is updated to pass through the current program_space,
	which will limit the returned locations to those in the current
	program space.

	RISC-V: Make T-Head testing pattern more generic
	On some T-Head vendor extensions, we test against the constant
	18446744073709551615 (2**64-1) to detect invalid immediate errors on -1.
	However, it heavily depends on the fact that the value used to print

	RISC-V: remove indirection from register tables

	To avoid old gcc, when generating 32-bit code, bogusly warning about

	an adjustment to EXTRACT_BITS() is needed: This macro shouldn't supply

	fbsd-nat: Fix thread_alive against a running thread.
	FreeBSD's ptrace fails requests with EBUSY against a running process.
	Report that the thread is alive instead of dead if ptrace fails with
	EBUSY.

	This fixes an internal error in the gdb.threads/detach-step-over.exp
	test where one process was detached while a thread in a second process
	was being stepped.  The core incorrectly assumed the stepping thread
	had vanished and discarded the pending stepping state.  When the
	thread later reported a SIGTRAP from completing the step, this
	triggered an assertion.

2023-08-14  John Baldwin  <jhb@FreeBSD.org>

	fbsd-nat: Fix several issues with detaching.
	- Detach from any child processes implicitly attached to by the kernel
	  due to fork following that have not yet been processed by GDB's
	  core.

	- Delete breakpoints before detaching.

	  inf-ptrace::detach does not do this (somewhat surprisingly), so add
	  an override to remove breakpoints from a process before detaching
	  from it.

	  This also requires explicitly draining any pending SIGTRAP events
	  for software breakpoints before detaching.  In particular, threads
	  may need their PC adjusted due to the software breakpoint before
	  being resumed after detach.  On more modern systems using the si_code
	  from SIGTRAP to identify software breakpoint traps, the PC is adjusted
	  in ::wait_1 as a side effect of parsing the event.  To support older
	  kernels, ::detach fixes up the PC for any SIGTRAP stop whose potential
	  new PC matches an existing software breakpoint.

	fbsd-nat: Fix resuming and waiting with multiple processes.
	I did not fully understand the requirements of multiple process
	support when I enabled it previously and several parts were broken.
	In particular, the resume method was only resuming a single process,
	and wait was not stopping other processes when reporting an event.

	To support multiple running inferiors, add a new per-inferior
	structure which trackes the number of existing and running LWPs for
	each process.  The structure also stores a ptid_t describing the
	set of LWPs currently resumed for each process.

	For the resume method, iterate over all non-exited inferiors resuming
	each process matching the passed in ptid rather than only resuming the
	current inferior's process for a wildcard ptid.  If a resumed process
	has a pending event, don't actually resume the process, but other
	matching processes without a pending event are still resumed in case
	the later call to the wait method requests an event from one of the
	processes without a pending event.

	For the wait method, stop other running processes before returning an
	event to the core.  When stopping a process, first check to see if an
	event is already pending.  If it is, queue the event to be reported
	later.  If not, send a SIGSTOP to the process and wait for it to stop.
	If the event reported by the wait is not for the SIGSTOP, queue the
	event and remember to ignore a future SIGSTOP event for the process.

	Note that, unlike the Linux native target, entire processes are
	stopped rather than individual LWPs.  In FreeBSD one can only wait on
	processes (via pid), not for an event from a specific thread.

	Other changes in this commit handle bookkeeping for the per-inferior
	data such as migrating the data to the new inferior in the follow_exec
	method.  The per-inferior data is created in the attach,
	create_inferior, and follow_fork methods.

2023-08-14  John Baldwin  <jhb@FreeBSD.org>

	fbsd-nat: Defer any ineligible events reported by wait.
	If wait_1 finds an event for a thread or process that does not match
	the set of threads and processes previously resumed, defer the event.
	If the event is for a specific thread, suspend the thread and continue
	the associated process before waiting for another event.

	One specific example of such an event is if a thread is created while
	another thread in the same process hits a breakpoint.  If the second
	thread's event is reported first, the target resume method does not
	yet "know" about the new thread and will not suspend it via
	PT_SUSPEND.  When wait is called, it will probably return the event
	from the first thread before the result of the step from second
	thread.  This is the case reported in PR 21497.

2023-08-14  John Baldwin  <jhb@FreeBSD.org>

	fbsd-nat: Add a list of pending events.
	The m_pending_events list stores a queue of deferred events that might
	be reported by the next call to the target's wait method.  The set of
	events that are eligible is filtered by the ptid passed to resume.

	For now this just replaces the list of vfork_done events.  A
	subsequent commit will reuse this to store other events.

	...
	and py-symtab-2.c:
	...
	static int __attribute__ ((used)) rr = 99;	/* line of other rr */
	... ]

	This passes with gdb-12-branch, and fails with gdb-13-branch.

	AFAIU the current code in symtab_index_entry::minimize makes the assumption
	that it's fine to store only one copy of rr in the gdb-index, because
	"print rr" will only ever print one, and always the same.

	But that fails to recognize that gdb supports gdb.lookup_static_symbols, which
	returns a list of variables rather than the first one.

	In other words, the current approach breaks feature parity between cooked
	index and gdb-index.

	Note btw that also debug-names has both instances:
	...

	gdbserver: Reinstall software single-step breakpoints in resume_stopped_resumed_lwps
	At the moment, while performing a software single-step, gdbserver fails
	to reinsert software single-step breakpoints for a LWP when
	interrupted by a signal in another thread.  This commit fixes this
	problem by reinstalling software single-step breakpoints in
	linux_process_target::resume_stopped_resumed_lwps in
	gdbserver/linux-low.cc.

	This bug was discovered due to a failing assert in maybe_hw_step()
	in gdbserver/linux-low.cc.  Looking at the backtrace revealed
	that the caller was linux_process_target::resume_stopped_resumed_lwps.
	I was uncertain whether the assert should still be valid when called
	from that method, so I tried hoisting the assert from maybe_hw_step
	to all callers except resume_stopped_resumed_lwps.  But running the
	new test case, described below, showed that merely eliminating the
	assert for this case was NOT a good fix - a study of the log file for
	the test showed that the single-step operation failed to occur.
	Instead GDB (via gdbserver) stopped at the next breakpoint that was
	hit.

	Zhiyong Yan had proposed a fix which resinserted software single-step
	breakpoints, albeit at a different location in linux-low.cc.  Testing
	revealed that, while running gdb.threads/pending-fork-event-detach,
	the executable associated with that test would die due to a SIGTRAP
	after the test program was detached.  Examination of the core file(s)
	showed that a breakpoint instruction had been left in program memory.
	Test results were otherwise very good, so Zhiyong was definitely on
	the right track!

	This commit causes software single-step breakpoint(s) to be inserted
	before the call to maybe_hw_step in resume_stopped_resumed_lwps.  This
	will cause 'has_single_step_breakpoints (thread)' to be true, so that
	the assert in maybe_hw_step...

	      /* GDBserver must insert single-step breakpoint for software
		 single step.  */
	      gdb_assert (has_single_step_breakpoints (thread));

	...will no longer fail.  And better still, the single-step breakpoints
	are reinstalled, so that stepping will actually work, even when
	interrupted.

	The C code for the test case was loosely adapted from the reproducer
	provided in Zhiyong's bug report for this problem.  The .exp file was
	copied from next-fork-other-thread.exp and then tweaked slightly.  As
	noted in a comment in next-fork-exec-other-thread.exp, I had to remove
	"on" from the loop for non-stop as it was failing on all architectures
	(including x86-64) that I tested.  I have a feeling that it ought to
	work, but this can be investigated separately and (re)enabled once it
	works.  I also increased the number of iterations for the loop running
	the "next" commands.  I've had some test runs which don't show the bug
	until the loop counter exceeded 100 iterations.  The C file for the
	new test uses shorter delays than next-fork-other-thread.c though, so
	it doesn't take overly long (IMO) to run this new test.

	Running the new test on a Raspberry Pi w/ a 32-bit (Arm) kernel and
	userland using a gdbserver build without the fix in this commit shows
	the following results:

			=== gdb Summary ===

	 # of unexpected core files	12
	 # of expected passes		3011
	 # of unexpected failures	14

	Each of the 12 core files were caused by the failed assertion in
	maybe_hw_step in linux-low.c.  These correspond to 12 of the
	unexpected failures.

	When the tests are run using a gdbserver build which includes the fix
	in this commit, the results are significantly better, but not perfect:

	FAIL: gdb.threads/next-fork-exec-other-thread.exp: fork_func=vfork: target-non-stop=on: non-stop=off: displaced-stepping=auto: i=143: next to other line
	FAIL: gdb.threads/next-fork-exec-other-thread.exp: fork_func=vfork: target-non-stop=on: non-stop=off: displaced-stepping=on: i=25: next to other line

			=== gdb Summary ===

	 # of expected passes		10178
	 # of unexpected failures	2

	I think that the two remaining failures are due to some different
	problem.  They are also racy - I've seen runs with no failures or only
	one failure, but never more than two.  Also, those runs were conducted
	with the loop count in next-fork-exec-other-thread.exp set to 200.
	During his testing of this fix and the new test case, Luis Machado
	found that this test was taking a long time and asked about ways to
	speed it up.  I then conducted additional tests in which I gradually
	reduced the loop count, timing each one, also noting the number of
	failures.  With the loop count set to 30, I found that I could still
	reliably reproduce the failures that Zhiyong reported (in which, with
	the proper settings, core files are created).  But, with the loop
	count set to 30, the other failures noted above were much less likely
	to show up.  Anyone wishing to investigate those other failures should
	set the loop count back up to 200.

	Running the new test on x86-64 and aarch64, both native and
	native-gdbserver shows no failures.

	Also, I see no regressions when running the entire test suite for
	armv7l-unknown-linux-gnueabihf (i.e.  the Raspberry Pi w/ 32-bit
	kernel+userland) with --target_board=native-gdbserver.  Additionally,
	using --target_board=native-gdbserver, I also see no regressions for
	the entire test suite for x86-64 and aarch64 running Fedora 38.

	The D front-end is now itself written in D, in order to build GDC, you
	will need a working GDC compiler (GCC version 9.1 or later).

	GCC changes:

	    - Add support for bootstrapping the D front-end.

	These add the required components in order to have a D front-end written
	in D itself.  Because the compiler front-end only depends on the core

	D front-end changes:

	    - Import dmd v2.098.0-beta.1.

	Druntime changes:

	    - Import druntime v2.098.0-beta.1.

	Phobos changes:

	Darwin, config: Revise host config fragment.
	There were two uses for the Darwin host config fragment:

	The first is to arrange for targets that support mdynamic-no-pic
	to be built with that enabled (since it makes a significant
	difference to the compiler performance).  We can be more specific
	in the application of this, since it only applies to 32b hosts
	plus powerpc64-darwin9.

	The second was to work around a tool bug where -fno-PIE was not
	propagated to the link stage.  This second use is redundant,
	since the buggy toolchain cannot bootstrap current GCC sources
	anyway.

	This makes the host fragment more specific and reduces the number
	of toolchains for which it is included which reduces clutter in

	On x86_64 it remains optional, but produces tool warnings after Darwin20, so
	we default to PIE executables there too.

	All (non-PowerPC) 64b Darwin platforms mandate PIC code and therefore force
	host_shared on (we issue a diagnostic if the user tries to configure them
	non-shared).

	However, this also means we cannot test the host_shared setting independently
	of the host_pie setting so that the logic for setting PICFLAG must be amended
	for Darwin.

	For Darwin versions required to have PIE executables, in the event that the
	user tries to configure these as --disable-host-pie, we issue a warning and
	override the setting.  These versions must also switch host_pie on even if it
	is not given in the configure line.  To cater for this we pass the current
	value of host_pie, as determined by top-level configure, to the GCC configure.


		* Makefile.def: Pass the enable-host-pie value to GCC configure.
		* configure.ac: Adjust the logic for shared and PIE host flags to
		ensure that PIE is passed for hosts that require it.

	gdb.ada/mi_var_access.exp
	The NUMCHILD value for the "A_String_Access" test differs for X86 and
	PowerPC.  The patch substitutes $decimal instead of "1" to match the value
	of NUMCHILD.

	The test "-var-update A_String_Access" generates different output depending
	on the value of VAROBJ_UPDATE_RESULT.TYPE_CHANGED.  If the value is true,
	the strings "new_type" and "new_num_children" are printed along with their
	values.

	The VAROBJ_UPDATE_RESULT.TYPE_CHANGED value is true on PowerPC which
	produces the output:

	  Expecting: ^(-var-update A_String_Access[
	  ]+)?(\^done,changelist=\[\{name="A_String_Access",in_scope="true",type_changed="false",has_more="0"\}\][

	  (gdb)
	  FAIL: gdb.ada/mi_var_access.exp: update at stop 2 (unexpected output)

	The patch adds a second possible result string for the test
	$re_varobj_update_result_type to match the case when type_changed is true.

	Currently for the mi_var_access.exp test VAROBJ_UPDATE_RESULT.TYPE_CHANGED
	is true on PowerPC and false on X86-64.

	Fixes 2 failures on PowerPC.

	x86: pack CPU flags in opcode table
	The table constantly growing in two dimensions (number of table entries

	RISC-V: Fix opcode entries of "vmsge{,u}.vx"
	Their check_func should be "match_never", not "match_opcode".  The reasons
	this error did not cause any disassembler errors are:

	1.  The problem will not reproduce if "no-aliases" is specified
	    (because macro instructions are handled as aliases).
	2.  If not, all affected compressed instructions or their aliases
	    precede before "vmsge{,u}.vx" macro instructions.

	However, it'll easily break if we reorder opcode entries.  This commit

	[gdb/symtab] Fix off-by-one error in cooked_indexer::recurse
	Test-case gdb.dwarf2/pr13961.exp contains:
	...

	    <31>   DW_AT_decl_line   : 1
	    <32>   DW_AT_sibling     : <0x44>
	...

	The DIE at 0x25 contains an intra-CU forward reference, and is deferred during
	DIE indexing in the cooked_index, by adding it to m_deferred_entries.

	The resulting cooked index entries are:
	...
	        [25] ((cooked_index_entry *) 0x333b5d0)
	        name:       foo
	        canonical:  foo
	        qualified:  foo
	        DWARF tag:  DW_TAG_class_type
	        flags:      0x0 []
	        DIE offset: 0x2a
	        parent:     ((cooked_index_entry *) 0)

	        [26] ((cooked_index_entry *) 0x333b630)
	        name:       foo
	        canonical:  foo
	        qualified:  foo::foo
	        DWARF tag:  DW_TAG_class_type
	        flags:      0x0 []
	        DIE offset: 0x25
	        parent:     ((cooked_index_entry *) 0x333b5d0) [foo]
	...

	Notice that 0x2a is the parent of 0x25, and that this is why the qualified
	name of 0x25 is "foo::foo", which is incorrect, it's supposed to be "foo".

	The parent is set here in cooked_indexer::make_index:
	...
	  for (const auto &entry : m_deferred_entries)
	    {
	      void *obj = m_die_range_map.find (entry.spec_offset);
	      cooked_index_entry *parent = static_cast<cooked_index_entry *> (obj);
	      m_index_storage->add (entry.die_offset, entry.tag, entry.flags,
				    entry.name, parent, m_per_cu);
	    }
	...
	and AFAICT, we store in m_die_range_map the parent of the respective
	spec_offset DIE (though that's not clear from the comment describing it).

	So, the root cause of this is that when we lookup the parent for DIE 0x25, we get
	m_die_range_map.find (0x2a) == 0x2a.

	This is an off-by-one error, fixed in cooked_indexer::recurse by:
	...
	-      CORE_ADDR start = form_addr (parent_entry->die_offset,
	+      CORE_ADDR start = form_addr (parent_entry->die_offset + 1,
	...
	which gives us:

	gdb/fortran: Align intrinsic/variable precedence
	Fortran allows variables and function to be named after language defined
	intrinsics as they are not reserved keywords. For example, the abs maths
	intrinsic can be hidden by a user declaring a variable called abs.

	The behavior before this patch was to favour the intrinsic, which meant
	that any variables named, for example "allocated", could not be
	inspected by GDB.

	This patch inverts this priority to bring GDB's behaviour closer to the
	Fortran language, where the user defined symbol can hide the intrinsic.

	Special care was need to prevent any C symbols from overriding either
	Fortran intrinsics or user defined variables. This was observed to be
	the case when GDB has access to symbols for abs from libm. This was
	solved by only allowing symbols not marked with language_fortran to be
	overridden.

	In total this brings the order of precedence to the following (highest
	first):

	    1. User defined Fortran variable or function.
	    2. Fortran intrinsic.
	    3. Symbols from languages other than Fortran.

	The sizeof intrinsic is now case insensitive. This is closer to the
	Fortran language.  I believe this change is safe enough as it increases
	the acceptance of the grammar, rather than restricts it. I.e. it should
	not break any existing scripts which rely on it. Unless of course they
	rely on SIZEOF being rejected.

	GDB built with GCC 13.

	No test suite regressions detected. Compilers: GCC, ACfL, Intel, Intel
	LLVM, NVHPC; Platforms: x86_64, aarch64.

	Existing tests in gdb.fortran cover the invocation of intrinsics
	including: intrinsics.exp, shape.exp, rank.exp, lbound-ubound.exp.

	[gdb/symtab] Find main language without symtab expansion
	When loading an executable using "file a.out", the language is set according
	to a.out, which can involve looking up the language of symbol "main", which
	will cause the symtab expansion for the containing CU.

	Expansion of lto debug info can be slow, so in commit d3214198119 ("[gdb] Use
	partial symbol table to find language for main") a feature was added to avoid
	the symtab expansion.

	This feature stopped working after commit 7f4307436fd ("Fix "start" for D,
	Rust, etc").

	[ The commit addresses problems related to command start, which requires finding
	the main function:
	- for language D, "main" was found instead of "D main", and
	- for Rust, the correct function was found, but attributed the wrong name
	  (not fully qualified). ]

	Reimplement the feature by adding
	cooked_index_functions::lookup_global_symbol_language.

	Tested on x86_64-linux.

	Consolidate calls to bfd_set_cacheable
	I noticed that some spots in gdb call bfd_set_cacheable after opening
	a BFD.

	The BFD file cache is a bit odd.  BFDs that are opened locally are
	unconditionally registered with the cache, and their underlying file
	descriptor will always be closed when bfd_cache_close_all is called.
	However, only "cacheable" BFDs will be eligible for reopening when
	needed -- and by default BFD decides that if a file descriptor is
	passed in, then it should not be cacheable.  If a non-cacheable BFD's
	file descriptor is closed, there is no offical way to reopen it.

	gdb needs to call bfd_cache_close_all, because some systems cannot
	start an executable when it has an open file descriptor referencing
	it.

	However, gdb also will sometimes passes an open file descriptor to the
	various BFD open functions.  And, due to lazy DWARF reading, gdb may
	also need to reopen these BFDs.

	Rather than having all the callers figure out when exactly to set the
	cacheable flag, I think it makes sense to consolidate this logic into
	the gdb_bfd.c wrapper functions.  It is ok to do this because gdb
	always passes a filename to these open functions, so reopening should
	work ok.

	Regression tested on x86-64 Fedora 38.

	SUMMARY: ThreadSanitizer: data race gdb/dwarf2/read.c:2033 in dw2_get_file_names_reader
	...

	The race happens when issuing the "file $exec" command.

	The race is between:
	- a worker thread writing the index cache, and in the process reading
	  dwarf2_per_cu_data::is_debug_type, and
	- the main thread writing to dwarf2_per_cu_data::files_read.

	The two bitfields dwarf2_per_cu_data::files_read and
	dwarf2_per_cu_data::is_debug_type share the same bitfield container.

	Fix this by making dwarf2_per_cu_data::files_read a packed<bool, 1>.

	Tested on x86_64-linux.

	PR symtab/30718
	Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=30718

	SUMMARY: ThreadSanitizer: data race gdb/dwarf2/read.c:3077 in dw_expand_symtabs_matching_file_matcher(dwarf2_per_objfile*, gdb::function_view<bool (char const*, bool)>)
	...

	The race happens when issuing the "file $exec" command.

	The race is between:
	- a worker thread writing the index cache, and in the process reading
	  dwarf2_per_cu_data::is_debug_type, and
	- the main thread writing to dwarf2_per_cu_data::mark.

	The two bitfields dwarf2_per_cu_data::mark and
	dwarf2_per_cu_data::is_debug_type share the same bitfield container.

	Fix this by making dwarf2_per_cu_data::mark a packed<unsigned int, 1>.

	Tested on x86_64-linux.

	PR symtab/30718
	Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=30718

	[gdb/testsuite] Extend gdb.base/index-cache.exp
	The test-case gdb.base/index-cache.exp uses only one source file, which
	contains main.

	While doing "file $exec", in set_initial_language a symbol lookup of "main" is
	done, causing the symtab containing main to be expanded.

	Handling of main is special, and a future optimization may skip the lookup and
	expansion.

	Reliably exercise:
	- the lookup of main, expanding the symtab containing main, by doing
	  "ptype main", and
	- the lookup of another symbol, expanding a symtab not containing main, by:
	  - adding another source file containing function foo, and
	  - doing "ptype foo".

	This triggered a segfault with target board native-extended-gdbserver, filed
	as PR symtab/30712, but that seems to be fixed by a previous commit in this
	series.

	Tested on x86_64-linux.

	SUMMARY: ThreadSanitizer: data race gdb/dwarf2/read.c:21513 in dwarf2_per_cu_data::get_header() const
	...

	The race happens when issuing the "file $exec" command.

	The race is between:
	- a worker thread writing the index cache, and in the process reading
	   dwarf2_per_cu_data::is_debug_type, and
	- the main thread writing to dwarf2_per_cu_data::m_header_read_in.

	The two bitfields dwarf2_per_cu_data::m_header_read_in and
	dwarf2_per_cu_data::is_debug_type share the same bitfield container.

	Fix this by making dwarf2_per_cu_data::m_header_read_in a packed<bool, 1>.

	Tested on x86_64-linux.

	SUMMARY: ThreadSanitizer: data race gdb/dwarf2/read.c:5564 in queue_comp_unit
	...

	The race happens when issuing the "file $exec" command.

	The race is between:
	- a worker thread writing the index cache, and in the process reading
	  dwarf2_per_cu_data::is_debug_type, and
	- the main thread expanding the CU containing main, and in the process setting
	  dwarf2_per_cu_data::queued.

	The two bitfields dwarf2_per_cu_data::queue and
	dwarf2_per_cu_data::is_debug_type share the same bitfield container.

	Fix this by making dwarf2_per_cu_data::queued a packed<bool, 1>.

	Tested on x86_64-linux.

	SUMMARY: ThreadSanitizer: data race bfd/cache.c:584 in bfd_open_file
	...

	The race happens when issuing the "file $exec" command.

	The race is between:
	- a worker thread getting the build id while writing the index cache, and in
	  the process reading bfd::format, and
	- the main thread calling find_main_name, and in the process setting
	  bfd::cacheable.

	The two bitfields bfd::cacheable and bfd::format share the same bitfield
	container.

	Fix this by capturing the build id in the main thread, and using the captured
	value in the worker thread.

	Likewise for the dwz build id, which likely suffers from the same issue.

	While we're at it, also move the creation of the cache directory to
	the index_cache_store_context constructor, to:
	- make sure there's no race between subsequent file commands, and
	- issue any related warning or error messages during the file command.

	Tested on x86_64-linux.

	SUMMARY: ThreadSanitizer: data race gdb/dwarf2/index-cache.c:76 in index_cache::enable()
	...

	The race happens when issuing a "file $exec" command followed by a
	"set index-cache enabled on" command.

	The race is between:
	- a worker thread reading index_cache::m_enabled to determine whether an
	  index-cache entry for $exec needs to be written
	  (due to command "file $exec"), and
	- the main thread setting index_cache::m_enabled
	  (due to command "set index-cache enabled on").

	Fix this by capturing the value of index_cache::m_enabled in the main thread,
	and using the captured value in the worker thread.

	Tested on x86_64-linux.

	[gdb/symtab] Remove superfluous handling of Ada main in write_cooked_index
	I filed PR29179 about the following FAIL in test-case
	gdb.ada/O2_float_param.exp with target board cc-with-gdb-index:
	...
	(gdb) break increment^M
	Function "increment" not defined.^M
	Make breakpoint pending on future shared library load? (y or [n]) n^M
	(gdb) FAIL: gdb.ada/O2_float_param.exp: scenario=all: gdb_breakpoint: \
	  set breakpoint at increment
	...

	The FAIL was a regression since commit 2cf349be0e3 ("Do not put linkage names
	into .gdb_index").

	Before that commit we had:
	...
	$ readelf -w foo > READELF
	$ grep callee.*increment READELF
	[1568] callee__increment: 5 [global, function]
	[3115] callee.increment: 5 [global, function]
	...
	but after only:
	...
	$ grep callee.*increment READELF
	[3115] callee.increment: 5 [global, function]
	...

	The regression was fixed by commit 67e83a0deef ("Fix regression in
	c-linkage-name.exp with gdb index"), which got us again:
	...
	$ grep callee.*increment READELF
	[1568] callee__increment: 5 [global, function]
	[3115] callee.increment: 5 [global, function]
	...

	The commit however did not claim that particular PR.  A subsequent commit,
	commit 5fea9794325 ("Improve Ada support in .gdb_index") did claim to fix it,
	together with commit dd05fc7071a ("Change .gdb_index de-duplication
	implementation").

	The commit 5fea9794325 contained the following addition in write_cooked_index:
	...
	+      if (entry->per_cu->lang () == language_ada)
	+	{
	+	  /* We want to ensure that the Ada main function's name
	+	     appears verbatim in the index.  However, this name will
	+	     be of the form "_ada_mumble", and will be rewritten by
	+	     ada_decode.  So, recognize it specially here and add it
	+	     to the index by hand.  */
	+	  if (entry->tag == DW_TAG_subprogram
	+	      && strcmp (main_for_ada, name) == 0)
	+	    {
	+	      /* Leave it alone.  */
	+	    }
	+	  else
	+	    {
	+	      /* In order for the index to work when read back into
	+		 gdb, it has to use the encoded name, with any
	+		 suffixes stripped.  */
	+	      std::string encoded = ada_encode (name, false);
	+	      name = obstack_strdup (&symtab->m_string_obstack,
	+				     encoded.c_str ());
	+	    }
	+	}
	...

	The code contains some special handling related to the Ada main function, so
	let's look at that one: foo.  Before commit 67e83a0deef we have:
	...
	$ grep foo.*function READELF
	[3733] foo: 7 [global, function]
	...
	and after:
	...
	$ grep foo.*function READELF
	[2738] _ada_foo: 7 [global, function]
	[3733] foo: 7 [global, function]
	...
	so that looks identical to the callee.increment case.

	At commit 5fea9794325, we have slightly different index numbers:
	...
	$ grep foo.*function READELF
	[1658] foo: 7 [global, function]
	[2738] _ada_foo: 7 [global, function]
	...
	but otherwise the same result.

	If we disable the special handling of the Ada main function like so:
	...
	-	  if (entry->tag == DW_TAG_subprogram
	+	  if (false && entry->tag == DW_TAG_subprogram
	...
	we still have the exact same result because:
	...
	(gdb) p main_for_ada
	$1 = 0x352e6a0 "_ada_foo"
	...
	and ada_encode ("_ada_foo", false) == "_ada_foo".

	The comment seems to be copied from debug_names::insert, which does indeed use
	ada_decode, while the code in write_cooked_index uses ada_encode instead.

	Remove the superfluous special handling of Ada main in write_cooked_index.

	Tested on x86_64-linux, with target boards unix and cc-with-gdb-index.

	them were removed here:

	    https://sourceware.org/pipermail/gdb-patches/2023-June/200023.html

	but I think this one landed after that patch.

	While DAP only supports Python 3.5 and later, f-strings were added in
	3.6, so remove this.

2023-08-03  Tom Tromey  <tromey@adacore.com>

	Use frame.name() in FrameDecorator
	A co-worker pointed out that gdb's DAP implementation might return an
	integer for the name of a stack frame, like:

	    {"id": 1, "name": 93824992310799, ...}

	This can be seen currently in the logs of the bt-nodebug.exp test
	case.

	What is happening is that FrameDecorator falls back on returning the
	PC when the frame's function symbol cannot be found, relying on the
	gdb core to look up the minsym and print its name.

	This can actually yield the wrong answer sometimes, because it falls
	into the get_frame_pc / get_frame_address_in_block problem -- if the
	frame is at a call to a noreturn function, the PC in this case might
	appear to be in the next function in memory.  For more on this, see:

	    https://sourceware.org/bugzilla/show_bug.cgi?id=8416

	and related bugs.

	However, there's a different approach we can take: the code here can
	simply use Frame.name.  This handles the PC problem correctly, and
	gets us the information we need.

	gdb: avoid double stop after failed breakpoint condition check
	This commit replaces this earlier commit:

	  commit 2e411b8c68eb2b035b31d5b00d940d4be1a0928b
	  Date:   Fri Oct 14 14:53:15 2022 +0100

	      gdb: don't always print breakpoint location after failed condition check

	and is a result of feedback received here[1].

	The original commit addressed a problem where, if a breakpoint
	condition included an inferior function call, and if the inferior
	function call failed, then GDB would announce the stop twice.  Here's
	an example of GDB's output before the above commit that shows the
	problem being addressed:

	  (gdb) break foo if (some_func ())
	  Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
	  (gdb) r
	  Starting program: /tmp/bpcond

	  Program received signal SIGSEGV, Segmentation fault.
	  0x0000000000401116 in some_func () at bpcond.c:5
	  5       return *p;
	  Error in testing condition for breakpoint 1:
	  The program being debugged stopped while in a function called from GDB.
	  Evaluation of the expression containing the function
	  (some_func) will be abandoned.
	  When the function is done executing, GDB will silently stop.

	  Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
	  5       return *p;
	  (gdb)

	The original commit addressed this issue in breakpoint.c, by spotting
	that the $pc had changed while evaluating the breakpoint condition,
	and inferring from this that GDB must have stopped elsewhere.

	However, the way in which the original commit suppressed the second
	stop announcement was to set bpstat::print to true -- this tells GDB
	not to print the frame during the stop announcement, and for the CLI
	this is fine, however, it was pointed out that for the MI this still
	isn't really enough.  Below is an example from an MI session after the
	above commit was applied, this shows the problem with the above
	commit:

	  *stopped
	  (gdb)

	Notice that we still see two '*stopped' lines, the first includes the
	full frame information, while the second has no frame information,
	this is a result of bpstat::print having been set.  Ideally, the
	second '*stopped' line should not be present.

	By setting bpstat::print I was addressing the problem too late, this
	flag really only changes how interp::on_normal_stop prints the stop
	event, and interp::on_normal_stop is called (indirectly) from the
	normal_stop function in infrun.c.  A better solution is to avoid
	calling normal_stop at all for the stops which should not be reported
	to the user, and this is what I do in this commit.

	This commit has 3 parts:

	  1. In breakpoint.c, revert the above commit,

	  2. In fetch_inferior_event (infrun.c), capture the stop-id before
	  calling handle_inferior_event.  If, after calling
	  handle_inferior_event, the stop-id has changed, then this indicates
	  that somewhere within handle_inferior_event, a stop was announced to
	  the user.  If this is the case then GDB should not call normal_stop,
	  and we should rely on whoever announced the stop to ensure that we
	  are in a PROMPT_NEEDED state, which means the prompt will be
	  displayed once fetch_inferior_event returns.  And,

	  3. In infcall.c, do two things:

	     (a) In run_inferior_call, after making the inferior call, ensure
	     that either async_disable_stdin or async_enable_stdin is called
	     to put the prompt state, and stdin handling into the correct
	     state based on whether the inferior call completed successfully
	     or not, and

	     (b) In call_thread_fsm::should_stop, call async_enable_stdin
	     rather than changing the prompt state directly.  This isn't
	     strictly necessary, but helped me understand this code more.
	     This async_enable_stdin call is only reached if normal_stop is
	     not going to be called, and replaces the async_enable_stdin call
	     that exists in normal_stop.  Though we could just adjust the
	     prompt state if felt (to me) much easier to understand when I
	     could see this call and the corresponding call in normal_stop.

	With these changes in place now, when the inferior call (from the
	breakpoint condition) fails, infcall.c leaves the prompt state as
	PROMPT_NEEDED, and leaves stdin registered with the event loop.

	Back in fetch_inferior_event GDB notices that the stop-id has changed
	and so avoids calling normal_stop.

	And on return from fetch_inferior_event GDB will display the prompt
	and handle input from stdin.

	As normal_stop is not called the MI problem is solved, and the test
	added in the earlier mentioned commit still passes just fine, so the
	CLI has not regressed.

	readelf sprintf optimisation
	This replaces sprintf and strcat calls with stpcpy, and makes use of
	sprintf return value rather than using strlen, for get_machine_flags.

	decode_NDS32_machine_flags made use of snprintf, which is arguably the
	"correct" way to do things if there can be a buffer overflow.  In this
	case I don't think there can be, the buffer is 1k in size which is at
	least 5 times more than needed.  What's more, snprintf returns the
	count of chars that would be output given no buffer limit, which means
	code like
	  r += snprintf (buf + r, size - r, ...);
	  r += snprintf (buf + r, size - r, ...);
	is just wrong.  There needs to be a check on the return value in order
	to prevent buf + r being out of bounds for the second snprintf call.

	BTW, if you look closely you'll see the return value of the decode
	functions is unused.  I admit to getting a little carried away with
	writing "out = stpcpy (out, ...):" in each of the decode functions and
	didn't notice that until get_machine_flags was trimmed down to a much
	smaller size.  When I did notice, I decided it's not such a bad thing.

	cris: sprintf sanitizer null destination pointer
	Simplify the sprintf calls, and use sprintf return value.  Older code
	in binutils avoided using the sprintf return count of chars printed,
	because with some older C libraries it wasn't reliable.  Nowadays it
	should be OK to use (and we already use the return value elsewhere).
	sprintf can't return an error status of -1 here.

	gdb: fix possible nullptr dereference in a remote_debug_printf call
	While working on another patch I triggered a segfault from within the
	function remote_target::discard_pending_stop_replies.  Turns out this
	was caused by a cut&paste error introduced in this commit:

	  commit df5ad102009c41ab4dfadbb8cfb8c8b2a02a4f78
	  Date:   Wed Dec 1 09:40:03 2021 -0500

	      gdb, gdbserver: detach fork child when detaching from fork parent

	This commit adds a remote_debug_printf call that was copied from
	earlier in the function, however, the new call wasn't updated to use
	the appropriate local variable.  The local variable that it is using
	might be nullptr, in which case we trigger undefined behaviour, and
	could crash, which is what I was seeing.

	Fixed by updating to use the correct local variable.

2023-08-03  Tsukasa OI  <research_trasio@irq.a4lg.com>

	RISC-V: Add support for 'Zvfh' and 'Zvfhmin'
	This commit adds support for recently ratified vector FP16 extensions:
	'Zvfh' and 'Zvfhmin'.

	This is based on:
	<https://github.com/riscv/riscv-v-spec/blob/master/v-spec.adoc#zvfhmin-vector-extension-for-minimal-half-precision-floating-point>
	<https://github.com/riscv/riscv-v-spec/blob/master/v-spec.adoc#zvfh-vector-extension-for-half-precision-floating-point>

	Despite not having any new instructions, it will be necessary since those
	extensions are already implemented in GCC.

	Note that however, in this commit, following dependencies are implemented.

	1.  'Zvfhmin' -> 'Zve32f'
	2.  'Zvfh' -> 'Zvfhmin' (not 'Zvfh' -> 'Zve32f' as in the documentation)
	3.  'Zvfh' -> 'Zfhmin'

	This is because the instructions and configurations supported by the
	'Zvfh' extension is a strict superset of the 'Zvfhmin' extension and
	'Zvfh' -> 'Zve32f' dependency is indirectly derived from that fact.

	bfd/ChangeLog:

		* elfxx-riscv.c (riscv_implicit_subsets): Add implications
		related to 'Zvfh' and 'Zvfhmin' extensions.
		(riscv_supported_std_z_ext) Add 'Zvfh' and 'Zvfhmin' to the list.

	RISC-V: Imply 'Zicsr' from 'Zve32x'

	and its resolution:

	Full paths in DAP stackTrace responses
	Vladimir Makaev noticed that, in some cases, a DAP stackTrace response
	would include a relative path name for the "path" component.

	This patch changes the frame decorator code to add a new DAP-specific
	decorator, and changes the DAP entry point to frame filters to use it.
	This decorator prefers the symtab's full name, and does not fall back
	to the solib's name.

	I'm not entirely happy with this patch, because if a user frame filter
	uses FrameDecorator, it may still do the wrong thing.  It would be
	better to have frame filters return symtab-like objects instead, or to
	have a separate method to return the full path to the source file.

	I also tend to think that the solib fallback behavior of
	FrameDecorator is a mistake.  If this is ever needed, it seems to me
	that it should be a separate method.

	    ../../gdb/amd-dbgapi-target.c:1071: internal-error: process_one_event: Assertion `runtime_state == AMD_DBGAPI_RUNTIME_STATE_UNLOADED' failed.
	    A problem internal to GDB has been detected,

	Before diving into why this error appears, let's explore how things are
	expected to work in normal circumstances.  When a process being debugged
	starts using the ROCm runtime, the following happens:

	- The runtime registers itself to the driver.
	- The driver creates a "runtime loaded" event and notifies the debugger
	  that a new event is available by writing to a file descriptor which is
	  registered in GDB's main event loop.
	- GDB core calls the callback associated with this file descriptor
	  (dbgapi_notifier_handler).  Because the amd-dbgapi-target is not
	  pushed at this point, the handler pulls the "runtime loaded" event
	  from the driver (this is the only event which can be available at this
	  point) and eventually pushes the amd-dbgapi-target on the inferior's
	  target stack.

	In a nutshell, this is the expected AMDGPU runtime activation process.

	From there, when new events are available regarding the GPU threads, the
	same file descriptor is written to.  The callback sees that the
	amd-dbgapi-target is pushed so marks the amd_dbgapi_async_event_handler.
	This will later cause amd_dbgapi_target::wait to be called.  The wait
	method pulls all the available events from the driver and handles them.
	The wait method returns the information conveyed by the first event, the
	other events are cached for later calls of the wait method.

	Note that because we are under the wait method, we know that the
	amd-dbgapi-target is pushed on the inferior target stack.  This implies
	that the runtime activation event has been seen already.  As a
	consequence, we cannot receive another event indicating that the runtime
	gets activated.  This is what the failing assertion checks.

	In the case when we have multiple inferiors however, there is a flaw in
	what have been described above.  If one inferior (let's call it inferior
	1) already has the amd-dbgapi-target pushed to its target stack and
	another inferior (inferior 2) activates the ROCm runtime, here is what
	can happen:

	- The driver creates the runtime activation for inferior 2 and writes to
	  the associated file descriptor.
	- GDB has inferior 1 selected and calls target_wait for some reason.
	- This prompts amd_dbgapi_target::wait to be called.  The method pulls
	  all events from the driver, including the runtime activation event for
	  inferior 2, leading to the assertion failure.

	The fix for this problem is simple.  To avoid such problem, we need to
	make sure that amd_dbgapi_target::wait only pulls events for the current
	inferior from the driver.  This is what this patch implements.

	This patch also includes a testcase which could fail before this patch.

	This patch has been tested on a system with multiple GPUs which had more
	chances to reproduce the original bug.  It has also been tested on top
	of the downstream ROCgdb port which has more AMDGPU related tests.  The
	testcase has been tested with `make check check-read1 check-readmore`.

	It is not possible to debug multiple processes simultaneously on all
	generations of AMDGPU devices.  As some tests will need to debug
	multiple inferiors using AMDGPU devices, we need to ensure that all
	devices available have the required capability.  Failing to do so would
	result in GDB not being able to debug all inferiors properly.

	The problem is that gdb.block_signals after first blocking a set of

	bpf: include, bfd, opcodes: add EF_BPF_CPUVER ELF header flags
	This patch adds support for EF_BPF_CPUVER bits in the ELF
	machine-dependent header flags.  These bits encode the BPF CPU
	version for which the object file has been compiled for.

	The BPF assembler is updated so it annotates the object files it
	generates with these bits.

	The BPF disassembler is updated so it honors EF_BPF_CPUVER to use the
	appropriate ISA version if the user didn't specify an explicit ISA
	version in the command line.  Note that a value of zero in
	EF_BPF_CPUVER is interpreted by the disassembler as "use the later
	supported version" (the BPF CPU versions start with v1.)

	The readelf utility is updated to pretty print EF_BPF_CPUVER when it
	prints out the ELF header:

	   $ readelf -h a.out
	   ELF Header:
	     ...

	bpf: gas: support relaxation of V4 jump instructions
	The BPF jump-always instruction (JA), like all other jump instructions
	in the ISA, get a signed 16-bit displacement target argument denoted
	in number of 64-bit words minus one.  This can sometimes be overflown.

	The BPF V4 ISA thus introduced support for a jump-always
	instruction (JAL) that gets a signed 32-bit displacement instead.

	This patch makes the BPF assembler to perform the following
	relaxations when the disp16 field gets overflown, unless the option
	-mno-relax is specified:

	  JA disp16  -> JAL disp32
	  Jxx disp16 -> Jxx +1; JA +1; JAL disp32

	Re-acquire GIL earlier in gdbpy_parse_and_eval
	Tom de Vries filed a bug about an intermittent gdb DAP failure -- and
	coincidentally, at the same time, Alexandra Hájková sent email about a
	somewhat similar failure.

	After looking into this for a while (with no results) using ASan and
	valgrind, I found that setting PYTHONMALLOC=malloc_debug found the bug
	instantly.

	The problem is that gdbpy_parse_and_eval releases the GIL while
	calling parse_and_eval, but fails to re-acquire it before calling
	value_to_value_object.  This is easily fixed by introducing a new
	scope.

	I wonder whether the test suite should unconditionally set

	MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targets
	Make the n64 ABI the default for 64-bit Linux targets specified with
	`-gnuabi64' suffix included in the target triplet, for configurations
	such as the Debian mips64el and mips64r6el ports.  Adjust testsuite
	configuration accordingly.

	There are the following regressions with the new target triplet:

	mips64-linux-gnuabi64  +FAIL: readelf -S bintest
	mips64-linux-gnuabi64  +FAIL: MIPS reloc estimation 1
	mips64el-linux-gnuabi64  +FAIL: readelf -S bintest
	mips64el-linux-gnuabi64  +FAIL: MIPS reloc estimation 1

	The `readelf' issue comes from a difference in section headers produced
	that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template
	does not match.  While there has been a precedent it does not appear to
	me that there is a clear advantage from adding more and more variations
	to the template rather than forking the existing template into multiple
	ones for a more exact match.  So this is best deferred to a separate
	discussion.

	The MIPS reloc estimation issue is an actual bug in `objdump', which
	discards a number of trailing entries from output here for n64 composed
	relocations:

	DYNAMIC RELOCATION RECORDS
	OFFSET           TYPE              VALUE
	0000000000000000 R_MIPS_NONE       *ABS*
	0000000000000000 R_MIPS_NONE       *ABS*

	and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not
	match even though ELF output produced is correct according to `readelf':

	Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries:
	  Offset          Info           Type           Sym. Value    Sym. Name
	000000000000  000000000000 R_MIPS_NONE
	                    Type2: R_MIPS_NONE
	                    Type3: R_MIPS_NONE

	                    Type2: R_MIPS_64
	                    Type3: R_MIPS_NONE

	As a genuine bug this has to be handled separately.

	The `mips-sgi-irix6' target only supports IRIX linker emulations, but

	Revert "MIPS: support mips*64 as CPU and gnuabi64 as ABI"
	This reverts commit 32f1c80375ebe8ad25d9805ee5889f0006c51e59.  It had
	two unrelated changes lumped together, one of which changed the meaning
	of the `mipsisa64*-*-linux*' target triplets, which was not properly
	evaluated.

	ldscripts/empty-address vs. xcoff
	The empty-address tests check that if a section is removed by ld due
	to being empty then properties of that section don't affect following
	addresses.  The xcoff backend doesn't remove the empty .data section
	created by empty-address-2* and empty-address-3* for some reason, and
	therefore fails the test.

	gdb: remove trailing empty line in target-delegates.c
	In a review [1], I pointed out that applying the patch, git would say:

	    .git/rebase-apply/patch:147: new blank line at EOF.

	However, since the empty line is in target-delegates.c (a generated
	file), there's nothing the author can do about it.  To avoid this
	comment coming up again in the future, change make-target-delegates.py
	to avoid the trailing empty line.  Do this by making it output empty
	lines before each entity, not after.

	Since this needs removing a newline output in gdbcopyright, adjust
	ada-unicode.py and gdbarch.py to avoid changes in the files they
	generate.

	Report supportsBreakpointLocationsRequest
	While looking at the DAP spec, I noticed that the breakpointLocations
	request is gated behind a capability.  This patch changes gdb to
	report this capability.

	I've also added a comment to explain the fact that arguments to
	breakpointLocations are not optional, even though the spec says they
	are.

	[gdb/build] Fix Wstringop-truncation in coff_getfilename
	When building gdb with -O2 -fsanitize-threads, I ran into
	a Werror=stringop-truncation.

	The problem is here in coff_getfilename in coffread.c:

	      strncpy (buffer, aux_entry->x_file.x_n.x_fname, FILNMLEN);
	      buffer[FILNMLEN] = '\0';
	...

	The constant FILNMLEN is expected to designate the size of
	aux_entry->x_file.x_n.x_fname, but that's no longer the case since commit
	60ebc257517 ("Fixes a buffer overflow when compiling assembler for the MinGW
	targets.").

	Fix this by using "sizeof (aux_entry->x_file.x_n.x_fname)" instead.

	[gdb/testsuite] Drop -nostdlib in gdb.dwarf2/typeddwarf.exp
	As reported in PR testsuite/30633, when running test-case
	gdb.dwarf2/typeddwarf.exp with target board native-gdbserver on Ubuntu
	22.04.2, we run into:
	...
	(gdb) continue^M
	Continuing.^M
	^M
	Program received signal SIGSEGV, Segmentation fault.^M
	0x0000000000000001 in ?? ()^M
	(gdb) FAIL: gdb.dwarf2/typeddwarf.exp: runto: run to main
	...

	We run into the FAIL as follows:
	- due to using gdbserver, we attach at the point of the first instruction, in
	  _start
	- we then set a breakpoint at main
	- the test-case is a .s file, that has main renamed to _start in the assembly,
	  but not in the debuginfo
	- setting a breakpoint at main sets the breakpoint at the same instruction
	  we're currently stopped at
	- continue doesn't hit the breakpoint, and we return out of _start, which
	  causes a sigsegv

	Note that this is for the amd64 case (using gdb.dwarf2/typeddwarf-amd64.S).
	For the i386 case (using gdb.dwarf2/typeddwarf.S), setting a breakpoint in
	main sets it one insn after function entry, and consequently the problem does
	not occur.

	The FAIL is a regression since commit 90cce6c0551 ("[gdb/testsuite] Add nopie
	in a few test-cases").

	Without nopie the executable is PIE, with nopie it's static instead.

	In the PIE case, we attach at the point of _start in the dynamic linker, and
	consequently we do not skip the breakpoint in main, and also don't run into
	the FAIL.

	Fix this by:
	- removing the -nostdlib setting, and
	- renaming _start to main in both .S files.

	The change to use -nostdlib and rename main to _start was originally added
	in commit 6edba76fe8b (submitted here:
	https://sourceware.org/pipermail/gdb-patches/2011-May/082657.html ) , I assume
	to fix the problem now fixed by using nopie.

	Tested on x86_64-linux.

	[gdb/tui] Fix assert in ~gdbpy_tui_window_maker
	In gdb/tui/tui-layout.c, we have:
	...
	static window_types_map known_window_types;
	...
	and in gdb/python/py-tui.c:
	...
	  /* A global list of all gdbpy_tui_window_maker objects.  */
	  static intrusive_list<gdbpy_tui_window_maker> m_window_maker_list;
	};

	/* See comment in class declaration above.  */

	intrusive_list<gdbpy_tui_window_maker>
	  gdbpy_tui_window_maker::m_window_maker_list;
	...

	With a gdb build with -O0 or -O2, the static destructor calling order seems to be:
	- first gdb/tui/tui-layout.c,
	- then gdb/python/py-tui.c.

	So when running test-case gdb.python/tui-window-factory.exp, we see the
	following order of events:
	- the destructor for known_window_types is called, which triggers calling the
	  destructor for the only element E of m_window_maker_list.  The destructor
	  destroys E, and also removes E from m_window_maker_list, leaving it empty.
	- the destructor for m_window_maker_list is called.  It's empty, so it's a nop.

	However, when building gdb with -O2 -flto=auto, the static destructor calling
	order seems to be reversed.

	Instead, we have these events:
	- the destructor for m_window_maker_list is called.  This doesn't destroy it's
	  only element E, but it does make m_window_maker_list empty.
	- the destructor for known_window_types is called, which triggers calling the
	  destructor for E.  An attempt is done to remove E from m_window_maker_list,
	  but we run into an assertion failure, because the list is empty.

	Fix this by checking is_linked () before attempting to remove from
	m_window_maker_list, similar to how things were addressed in commit 995a34b1772
	("Guard against frame.c destructors running before frame-info.c's").

	Tested on x86_64-linux.

	Export gdb.block_signals and create gdb.Thread
	While working on an experiment, I realized that I needed the DAP
	block_signals function.  I figured other developers may need it as
	well, so this patch moves it from DAP to the gdb module and exports
	it.

	I also added a new subclass of threading.Thread that ensures that
	signals are blocked in the new thread.

	Finally, this patch slightly rearranges the documentation so that
	gdb-side threading issues and functions are all discussed in a single
	node.

	gdb: two changes to linux_nat_debug_printf calls in linux-nat.c
	This commit adjusts some of the debug output in linux-nat.c, but makes
	no other functional changes to GDB.

	In resume_lwp I've added the word "sibling" to one of the debug
	messages.  All the other debug messages in this function talk about
	operating on the sibling thread, so I think it makes sense, for
	consistency, if the message I've updated also talks about the sibling
	thread.

	In resume_stopped_resumed_lwps I've reordered the condition checks so
	that the vfork-parent check now happens after the checks for whether
	the thread is already resumed or not.  This makes no functional
	difference to GDB, but does, I think, mean we see more helpful debug
	messages first.

	Consider the situation where a vfork-parent thread is already resumed,
	and resume_stopped_resumed_lwps is called.  Previously the message
	saying that the thread was not being resumed due to being a
	vfork-parent, was printed.  This might give the impression that the
	thread is left in a not resumed state, which is misleading.

	After this change we now get a message saying that the thread is not
	being resumed due to it not being stopped (i.e. is already resumed).
	With this message the already resumed nature of the thread is much
	clearer.

	Fixed this to use $binfile, now I can easily change the name of the

	sim/bpf: desCGENization of the BPF simulator
	The BPF port in binutils has been rewritten (commit
	d218e7fedc74d67837d2134120917f4ac877454c) in order to not be longer
	based on CGEN.  Please see that commit log for more information.

	This patch updates the BPF simulator accordingly.  The new
	implementation is much simpler and it is based on the new BPF opcodes.

	Tested with target bpf-unknown-none with both 64-bit little-endian
	host and 32-bit little-endian host.

	Note that I have not tested in a big-endian host yet.  I will do so
	once this lands upstream so I can use the GCC compiler farm.

2023-07-21  Jose E. Marchesi  <jose.marchesi@oracle.com>

	DesCGENization of the BPF binutils port
	CGEN is cool, but the BPF architecture is simply too bizarre for it.

	The weird way of BPF to handle endianness in instruction encoding, the
	weird C-like alternative assembly syntax, the weird abuse of
	multi-byte (or infra-byte) instruction fields as opcodes, the unusual
	presence of opcodes beyond the first 32-bits of some instructions, are
	all examples of what makes it a PITA to continue using CGEN for this
	port.  The bpf.cpu file is becoming so complex and so nested with
	p-macros that it is very difficult to read, and quite challenging to
	update.  Also, every time we are forced to change something in CGEN to
	accommodate BPF requirements (which is often) we have to do extensive
	testing to make sure we do not break any other target using CGEN.

	This is getting un-maintenable.

	So I have decided to bite the bullet and revamp/rewrite the port so it
	no longer uses CGEN.  Overall, this involved:

	* To remove the cpu/bpf.{cpu,opc} descriptions.

	* To remove the CGEN generated files.

	* To replace the CGEN generated opcodes table with a new hand-written
	  opcodes table for BPF.

	* To replace the CGEN generated disassembler wih a new disassembler
	  that uses the new opcodes.

	* To replace the CGEN generated assembler with a new assembler that uses the
	  new opcodes.

	* To replace the CGEN generated simulator with a new simulator that uses the
	  new opcodes. [This is pushed in GDB in another patch.]

	* To adapt the build systems to the new situation.

	Additionally, this patch introduces some extensions and improvements:

	* A new BPF relocation BPF_RELOC_BPF_DISP16 plus corresponding ELF
	  relocation R_BPF_GNU_64_16 are added to the BPF BFD port.  These
	  relocations are used for section-relative 16-bit offsets used in
	  load/store instructions.

	* The disassembler now has support for the "pseudo-c" assembly syntax of
	  BPF.  What dialect to use when disassembling is controlled by a command
	  line option.

	* The disassembler now has support for dumping instruction immediates in
	  either octal, hexadecimal or decimal.  The used output base is controlled
	  by a new command-line option.

	* The GAS BPF test suite has been re-structured and expanded in order to
	  test the disassembler pseudoc syntax support.  Minor bugs have been also
	  fixed there.  The assembler generic tests that were disabled for bpf-*-*
	  targets due to the previous implementation of pseudoc syntax are now
	  re-enabled.  Additional tests have been added to test the new features of
	  the assembler.  .dump files are no longer used.

	* The linker BPF test suite has been adapted to the command line options
	  used by the new disassembler.

	The result is very satisfactory.  This patchs adds 3448 lines of code
	and removes 10542 lines of code.

	Tested in:

	* Target bpf-unknown-none with 64-bit little-endian host and 32-bit
	  little-endian host.

	* Target x86-64-linux-gnu with --enable-targets=all

	Note that I have not tested in a big-endian host yet.  I will do so
	once this lands upstream so I can use the GCC compiler farm.

	I have not included ChangeLog entries in this patch: these would be
	massive and not very useful, considering this is pretty much a rewrite
	of the port.  I beg the indulgence of the global maintainers.

	gdb/solib-rocm: limit the number of opened file descriptors
	ROCm programs can load a high number of compute kernels on GPU devices,
	especially if lazy code-object loading have been disabled.  Each code
	object containing such program is loaded once for each device available,
	and each instance is reported by GDB as an individual shared library.

	We came across situations where the number of shared libraries opened by
	GDB gets higher than the allowed number of opened files for the process.
	Increasing the opened files limit works around the problem, but there is a
	better way this patch proposes to follow.

	Under the hood, the GPU code objects are embedded inside the host
	application binary and shared library binaries.  GDB currently opens the
	underlying file once for each shared library it sees.  That means that
	the same file is re-opened every time a code object is loaded on a GPU.

	This patch proposes to only open each underlying file once.  This is
	done by implementing a reference counting mechanism so the underlying
	file is opened when the underlying file first needs to be opened, and
	closed when the last BFD using the underlying file is closed.

	On a program where GDB used to open about 1500 files to load all shared
	libraries, this patch makes it so only 54 opened file descriptors are
	needed.

	I have tested this patch on downstream ROCgdb's full testsuite and
	upstream GDB testsuite with no regression.

	[gdb/symtab] Add optimized out static var to cooked index
	Consider the test-case:
	...
	$ cat main.c
	int main (void) { return 0; }
	$ cat static-optimized-out.c
	static int aaa;
	...
	compiled like this:
	...
	$ gcc-12 static-optimized-out.c main.c -g -O2 -flto
	...

	There's a difference in behaviour depending on symtab expansion state:
	...
	$ gdb -q -batch a.out -ex "print aaa"
	No symbol "aaa" in current context.
	$ gdb -q -batch a.out -ex "maint expand-symtab" -ex "print aaa"
	$1 = <optimized out>
	...

	The reason for the difference is that the optimized out variable aaa:
	...
	 <1><104>: Abbrev Number: 2 (DW_TAG_variable)
	    <105>   DW_AT_name        : aaa
	    <109>   DW_AT_decl_file   : 1
	    <10a>   DW_AT_decl_line   : 18
	    <10b>   DW_AT_decl_column : 12
	    <10c>   DW_AT_type        : <0x110>
	...
	is not added to the cooked index because of this clause in abbrev_table::read:
	...
	     else if (!has_location && !has_specification_or_origin && !has_external
		       && cur_abbrev->tag == DW_TAG_variable)
		cur_abbrev->interesting = false;

	and with gcc 7.5.0 and clang 13.0.1, for which we still consistently get:

	[gdb/tui] Fix superfluous newline for long prompt
	In test-case gdb.tui/long-prompt.exp, with a prompt of 40 chars, the same size
	as the terminal width, we get a superfluous newline at line 19:
	...
	16 (gdb) set prompt 123456789A123456789B123
	17 456789C123456789>
	18 123456789A123456789B123456789C123456789>
	19
	20 123456789A123456789B123456789C123456789>
	21 set prompt (gdb)
	22 (gdb)
	...
	as well as a superfluous repetition of the prompt at line 20 once we type the
	's' starting "set prompt".

	I traced the superfluous newline back to readline's readline_internal_setup,
	that does:
	...
	  /* If we're not echoing, we still want to at least print a prompt, because
	     rl_redisplay will not do it for us.  If the calling application has a
	     custom redisplay function, though, let that function handle it. */
	  if (_rl_echoing_p == 0 && rl_redisplay_function == rl_redisplay)
	    ...
	  else
	    {
	      if (rl_prompt && rl_already_prompted)
		rl_on_new_line_with_prompt ();
	      else
		rl_on_new_line ();
	      (*rl_redisplay_function) ();
	...
	and then we hit the case that calls rl_on_new_line_with_prompt, which does:
	...
	  /* If the prompt length is a multiple of real_screenwidth, we don't know
	     whether the cursor is at the end of the last line, or already at the
	     beginning of the next line. Output a newline just to be safe. */
	  if (l > 0 && (l % real_screenwidth) == 0)
	    _rl_output_some_chars ("\n", 1);
	...

	This doesn't look like a readline bug, because the behaviour matches the
	comment.

	[ And the fact that the output of the newline doesn't happen in the scope of
	tui_redisplay_readline means it doesn't get the prompt wrap detection
	treatment, causing start_line to be incorrect, which causes the superfluous
	repetition of the prompt. ]

	I looked at ways to work around this, and managed by switching off
	rl_already_prompted, which we set to 1 in tui_rl_startup_hook:
	...
	/* Readline hook to redisplay ourself the gdb prompt.
	   In the SingleKey mode, the prompt is not printed so that
	   the command window is cleaner.  It will be displayed if
	   we temporarily leave the SingleKey mode.  */
	static int
	tui_rl_startup_hook (void)
	{
	  rl_already_prompted = 1;
	  if (tui_current_key_mode != TUI_COMMAND_MODE
	      && !gdb_in_secondary_prompt_p (current_ui))
	    tui_set_key_mode (TUI_SINGLE_KEY_MODE);
	  tui_redisplay_readline ();
	  return 0;
	}
	...

	Then I started looking at why rl_already_prompted is set to 1.

	The use case for rl_already_prompted seems to be:
	- app (application, the readline user) outputs prompt,
	- app sets rl_already_prompted to 1, and
	- app calls readline, which calls rl_on_new_line_with_prompt, which figures
	  out how long the prompt is, and sets a few readline variables accordingly,
	  which can be used in the following call to rl_redisplay_function.

	AFAICT, TUI does not fit this pattern.  It does not output an initial prompt,
	rather it writes the prompt in every rl_redisplay_function.  It doesn't use
	the variables set by rl_on_new_line_with_prompt, instead it figures stuff out
	by itself.

	Fix this by removing the rl_already_prompted setting.

	Also remove the call to tui_redisplay_readline, it's not necessary, the
	function is called anyway.

	Tested on x86_64-linux, no regressions.

	Fix gdb.Inferior.read_memory without execution (PR dap/30644)
	Andrew reported that the previous change to gdb.Inferior.read_memory &
	friends introducing scoped_restore_current_inferior_for_memory broke
	gdb.dap/stop-at-main.exp.  This is also reported as PR dap/30644.

	The root of the problem is that all the methods that now use
	scoped_restore_current_inferior_for_memory cause GDB to crash with a
	failed assert if they are run on an inferior that is not yet started.

	E.g.:

	 (gdb) python i = gdb.selected_inferior ()
	 (gdb) python i.read_memory (4,4)
	 gdb/thread.c:626: internal-error: any_thread_of_inferior: Assertion `inf->pid != 0' failed.

	This patch fixes the problem by removing
	scoped_restore_current_inferior_for_memory's ctor ptid parameter and
	the any_thread_of_inferior calls completely, and making
	scoped_restore_current_inferior_for_memory switch inferior_ptid to a
	pid ptid.

	I was a little worried that some port might be assuming inferior_ptid
	points at a thread in the xfer_partial memory access routines.  We
	know that anything that supports forks must not assume that, due to
	how detach_breakpoints works.  I looked at a number of xfer_partial
	implementations, and didn't see anything that is looking at
	inferior_ptid in a way that would misbehave.  I'm thinking that we
	could go forward with this and just fix ports if they break.

	While on some ports like on AMD GPU we have thread-specific address
	spaces, and so when accessing memory for those address spaces, we must
	have the right thread context (via inferior_ptid) selected, in
	Inferior.read_memory, we only have the inferior to work with, so this
	API as is can't be used to access thread-specific address spaces.
	IOW, it can only be used to access the global address space that is
	visible to both the CPU and the GPUs.

	In proc-service.c:ps_xfer_memory, the other spot using
	scoped_restore_current_inferior_for_memory, we're always accessing
	per-inferior memory.

	If we end up using scoped_restore_current_inferior_for_memory later to
	set up the context to read memory from a specific thread, then we can
	add an alternative ctor that takes a thread_info pointer, and make
	inferior_ptid point to the thread, for example.

	New test added to gdb.python/py-inferior.exp, exercising
	Inferior.read_memory without execution.

	No regressions on native and extended-gdbserver x86_64 GNU/Linux.

	gdb/amd-dbgapi-target: Use inf param in detach
	Current implementation of amd_dbgapi_target::detach (inferior *, int)
	does the following:

	  remove_breakpoints_inf (current_inferior ());
	  detach_amd_dbgapi (inf);
	  beneath ()->detach (inf, from_tty);

	I find that using a mix of `current_inferior ()` and `inf` disturbing.
	At this point, we know that both are the same (target_detach does assert
	that `inf == current_inferior ()` before calling target_ops::detach).

	To improve consistency, this patch replaces `current_inferior ()` with
	`inf` in amd_dbgapi_target::detach.

	gdb/testsuite: remove use of sleep from gdb.base/foll-vfork.exp
	While working on gdb.base/foll-vfork.exp I noticed that there are
	several random 'sleep' calls throughout the test.

	The comment suggests these are to allow for output from a vforked
	child to arrive, but in each case the test is about to close and
	restart GDB, so I don't see how random output from a child process
	could impact testing.

	I removed the sleep calls and couldn't reproduce any failures from
	this test, I left the test running for a couple of hours, and tried
	loading my machine, and the test seems fine with these removed.

	I've left this as a separate commit so that if, in the future, someone
	can show that these are required, it will be easy to revert this one
	patch and bring them back.

	There should be no change in what is tested after this commit.

	gdb/testsuite: expand gdb.base/foll-vfork.exp
	This commit provides tests for all of the bugs fixed in the previous
	four commits, this is achieved by expanding gdb.base/foll-vfork.exp to
	run with different configurations:

	  * target-non-stop on/off
	  * non-stop on/off
	  * schedule-multiple on/off

	We don't test with schedule-multiple on if we are using a remote
	target, this is due to bug gdb/30574.  I've added a link to that bug
	in this commit, but all this commit does is expose that bug, there's
	no fixes here.

	Some of the bugs fixed in the previous commits are very timing
	dependent, as such, they don't always show up.  I've had more success
	when running this test on a very loaded machine -- I usually run ~8
	copies of the test in parallel, then the bugs would normally show up
	pretty quickly.

	Other than running the test in more configurations, I've not made any
	changes to what is actually being tested, other than in one place
	where, when testing with non-stop mode, GDB stops in a different
	inferior, as such I had to add a new 'inferior 2' call, this can be
	found in vfork_relations_in_info_inferiors.

	I have cleaned things up a little, for example, making use of
	proc_with_prefix to remove some with_test_prefix calls.

2023-07-17  Andrew Burgess  <aburgess@redhat.com>

	gdb: don't resume vfork parent while child is still running
	Like the last few commit, this fixes yet another vfork related issue.
	Like the commit titled:

	  gdb: don't restart vfork parent while waiting for child to finish

	which addressed a case in linux-nat where we would try to resume a
	vfork parent, this commit addresses a very similar case, but this time
	occurring in infrun.c.  Just like with that previous commit, this bug
	results in the assert:

	  x86-linux-dregs.c:146: internal-error: x86_linux_update_debug_registers: Assertion `lwp_is_stopped (lwp)' failed.

	In this case the issue occurs when target-non-stop is on, but non-stop
	is off, and again, schedule-multiple is on.  As with the previous
	commit, GDB is in follow-fork-mode child.  If you have not done so, it
	is worth reading the earlier commit as many of the problems leading to
	the failure are the same, they just appear in a different part of GDB.

	Here are the steps leading to the assertion failure:

	  1. The user performs a 'next' over a vfork, GDB stop in the vfork
	  child,

	  2. As we are planning to follow the child GDB sets the vfork_parent
	  and vfork_child member variables in the two inferiors, the
	  thread_waiting_for_vfork_done member is left as nullptr, that member
	  is only used when GDB is planning to follow the parent inferior,

	  3. The user does 'continue', our expectation is that the vfork child
	  should resume, and once that process has exited or execd, GDB should
	  detach from the vfork parent.  As a result of the 'continue' GDB
	  eventually enters the proceed function,

	  4. In proceed we selected a ptid_t to resume, because
	  schedule-multiple is on we select minus_one_ptid (see
	  user_visible_resume_ptid),

	  5. As GDB is running in all-stop on top of non-stop mode, in the
	  proceed function we iterate over all threads that match the resume
	  ptid, which turns out to be all threads, and call
	  proceed_resume_thread_checked.  One of the threads we iterate over
	  is the vfork parent thread,

	  6. As the thread passed to proceed_resume_thread_checked doesn't
	  match any of the early return conditions, GDB will set the thread
	  resumed,

	  7. As we are resuming one thread at a time, this thread is seen by
	  the lower layers (e.g. linux-nat) as the "event thread", which means
	  we don't apply any of the checks, e.g. is this thread a
	  vfork parent, instead we assume that GDB core knows what it's doing,
	  and linux-nat will resume the thread, we have now incorrectly set
	  running the vfork parent thread when this thread should be waiting
	  for the vfork child to complete,

	  8. Back in the proceed function GDB continues to iterate over all
	  threads, and now (correctly) resumes the vfork child thread,

	  8. As the vfork child is still alive the kernel holds the vfork
	  parent stopped,

	  9. Eventually the child performs its exec and GDB is sent and EXECD
	  event.  However, because the parent is resumed, as soon as the child
	  performs its exec the vfork parent also sends a VFORK_DONE event to
	  GDB,

	  10. Depending on timing both of these events might seem to arrive in
	  GDB at the same time.  Normally GDB expects to see the EXECD or
	  EXITED/SIGNALED event from the vfork child before getting the
	  VFORK_DONE in the parent.  We know this because it is as a result of
	  the EXECD/EXITED/SIGNALED that GDB detaches from the parent (see
	  handle_vfork_child_exec_or_exit for details).  Further the comment
	  in target/waitstatus.h on TARGET_WAITKIND_VFORK_DONE indicates that
	  when we remain attached to the child (not the parent) we should not
	  expect to see a VFORK_DONE,

	  11. If both events arrive at the same time then GDB will randomly
	  choose one event to handle first, in some cases this will be the
	  VFORK_DONE.  As described above, upon seeing a VFORK_DONE GDB
	  expects that (a) the vfork child has finished, however, in this case
	  this is not completely true, the child has finished, but GDB has not
	  processed the event associated with the completion yet, and (b) upon
	  seeing a VFORK_DONE GDB assumes we are remaining attached to the
	  parent, and so resumes the parent process,

	  12. GDB now handles the EXECD event.  In our case we are detaching
	  from the parent, so GDB calls target_detach (see
	  handle_vfork_child_exec_or_exit),

	  13. While this has been going on the vfork parent is executing, and
	  might even exit,

	  14. In linux_nat_target::detach the first thing we do is stop all
	  threads in the process we're detaching from, the result of the stop
	  request will be cached on the lwp_info object,

	  15. In our case the vfork parent has exited though, so when GDB
	  waits for the thread, instead of a stop due to signal, we instead
	  get a thread exited status,

	  16. Later in the detach process we try to resume the threads just
	  prior to making the ptrace call to actually detach (see
	  detach_one_lwp), as part of the process to resume a thread we try to
	  touch some registers within the thread, and before doing this GDB
	  asserts that the thread is stopped,

	  17. An exited thread is not classified as stopped, and so the assert
	  triggers!

	Just like with the earlier commit, the fix is to spot the vfork parent
	status of the thread, and not resume such threads.  Where the earlier
	commit fixed this in linux-nat, in this case I think the fix should
	live in infrun.c, in proceed_resume_thread_checked.  This function
	already has a similar check to not resume the vfork parent in the case
	where we are planning to follow the vfork parent, I propose adding a
	similar case that checks for the vfork parent when we plan to follow
	the vfork child.

	This new check will mean that at step #6 above GDB doesn't try to
	resume the vfork parent thread, which prevents the VFORK_DONE from
	ever arriving.  Once GDB sees the EXECD/EXITED/SIGNALLED event from
	the vfork child GDB will detach from the parent.

	There's no test included in this commit.  In a subsequent commit I
	will expand gdb.base/foll-vfork.exp which is when this bug would be
	exposed.

	If you do want to reproduce this failure then you will for certainly
	need to run the gdb.base/foll-vfork.exp test in a loop as the failures
	are all very timing sensitive.  I've found that running multiple
	copies in parallel makes the failure more likely to appear, I usually
	run ~6 copies in parallel and expect to see a failure after within
	10mins.

	gdb: fix an issue with vfork in non-stop mode
	This commit fixes a bug introduced by this commit:

	  commit d8bbae6ea080249c05ca90b1f8640fde48a18301
	  Date:   Fri Jan 14 15:40:59 2022 -0500

	      gdb: fix handling of vfork by multi-threaded program (follow-fork-mode=parent, detach-on-fork=on)

	The problem can be seen in this GDB session:

	  $ gdb -q
	  (gdb) set non-stop on
	  (gdb) file ./gdb/testsuite/outputs/gdb.base/foll-vfork/foll-vfork
	  Reading symbols from ./gdb/testsuite/outputs/gdb.base/foll-vfork/foll-vfork...
	  (gdb) tcatch vfork
	  Catchpoint 1 (vfork)
	  (gdb) run
	  Starting program: /tmp/gdb/testsuite/outputs/gdb.base/foll-vfork/foll-vfork

	  Temporary catchpoint 1 (vforked process 1375914), 0x00007ffff7d5043c in vfork () from /lib64/libc.so.6
	  (gdb) bt
	  #0  0x00007ffff7d5043c in vfork () from /lib64/libc.so.6
	  #1  0x00000000004011af in main (argc=1, argv=0x7fffffffad88) at .../gdb/testsuite/gdb.base/foll-vfork.c:32
	  (gdb) finish
	  Run till exit from #0  0x00007ffff7d5043c in vfork () from /lib64/libc.so.6
	  [Detaching after vfork from child process 1375914]
	  No unwaited-for children left.
	  (gdb)

	Notice the "No unwaited-for children left." error.  This is incorrect,
	given where we are stopped there's no reason why we shouldn't be able
	to use "finish" to return to the main frame.

	When the inferior is stopped as a result of the 'tcatch vfork', the
	inferior is in the process of performing the vfork, that is, GDB has
	seen the VFORKED event, but has not yet attached to the new child
	process, nor has the child process been resumed.

	However, GDB has seen the VFORKED, and, as we are going to follow the
	parent process, the inferior for the vfork parent will have its
	thread_waiting_for_vfork_done member variable set, this will point to
	the one and only thread that makes up the vfork parent process.

	When the "finish" command is used GDB eventually ends up in the
	proceed function (in infrun.c), in here we pass through all the
	function until we eventually encounter this 'else if' condition:

	   else if (!cur_thr->resumed ()
		     && !thread_is_in_step_over_chain (cur_thr)
		     /* In non-stop, forbid resuming a thread if some other thread of
			that inferior is waiting for a vfork-done event (this means
			breakpoints are out for this inferior).  */
		     && !(non_stop
			  && cur_thr->inf->thread_waiting_for_vfork_done != nullptr))
	      {

	The first two of these conditions will both be true, the thread is not
	already resumed, and is not in the step-over chain, however, the third
	condition, this one:

		     && !(non_stop
			  && cur_thr->inf->thread_waiting_for_vfork_done != nullptr))

	is false, and this prevents the thread we are trying to finish from
	being resumed.  This condition is false because (a) non_stop is true,
	and (b) cur_thr->inf->thread_waiting_for_vfork_done is not
	nullptr (see above for why).

	Now, if we check the comment embedded within the condition it says:

	     /* In non-stop, forbid resuming a thread if some other thread of
	        that inferior is waiting for a vfork-done event (this means
	        breakpoints are out for this inferior).  */

	And this makes sense, if we have a vfork parent with two thread, and
	one thread has performed a vfork, then we shouldn't try to resume the
	second thread.

	However, if we are trying to resume the thread that actually performed
	a vfork, then this is fine.  If we never resume the vfork parent then
	we'll never get a VFORK_DONE event, and so the vfork will never
	complete.

	Thus, the condition should actually be:

	     && !(non_stop
		  && cur_thr->inf->thread_waiting_for_vfork_done != nullptr
		  && cur_thr->inf->thread_waiting_for_vfork_done != cur_thr))

	This extra check will allow the vfork parent thread to resume, but
	prevent any other thread in the vfork parent process from resuming.
	This is the same condition that already exists in the all-stop on a
	non-stop-target block earlier in the proceed function.

	My actual fix is slightly different to the above, first, I've chosen
	to use a nested 'if' check instead of extending the original 'else if'
	check, this makes it easier to write a longer comment explaining
	what's going on, and second, instead of checking 'non_stop' I've
	switched to checking 'target_is_non_stop_p'.  In this context this is
	effectively the same thing, a previous 'else if' block in proceed
	already handles '!non_stop && target_is_non_stop_p ()', so by the time
	we get here, if 'target_is_non_stop_p ()' then we must be running in
	non_stop mode.

	Both of these tweaks will make the next patch easier, which is a
	refactor to merge two parts of the proceed function, so this nested
	'if' block is not going to exist for long.

	For testing, there is no test included with this commit.  The test was
	exposed when using a modified version of the gdb.base/foll-vfork.exp
	test script, however, there are other bugs that are exposed when using
	the modified test script.  These bugs will be addressed in subsequent
	commits, and then I'll add the updated gdb.base/foll-vfork.exp.

	If you wish to reproduce this failure then grab the updates to
	gdb.base/foll-vfork.exp from the later commit and run this test, the
	failure is always reproducible.

	gdb: don't restart vfork parent while waiting for child to finish
	While working on a later patch, which changes gdb.base/foll-vfork.exp,
	I noticed that sometimes I would hit this assert:

	  x86_linux_update_debug_registers: Assertion `lwp_is_stopped (lwp)' failed.

	I eventually tracked it down to a combination of schedule-multiple
	mode being on, target-non-stop being off, follow-fork-mode being set
	to child, and some bad timing.  The failing case is pretty simple, a
	single threaded application performs a vfork, the child process then
	execs some other application while the parent process (once the vfork
	child has completed its exec) just exits.  As best I understand
	things, here's what happens when things go wrong:

	  1. The parent process performs a vfork, GDB sees the VFORKED event
	  and creates an inferior and thread for the vfork child,

	  2. GDB resumes the vfork child process.  As schedule-multiple is on
	  and target-non-stop is off, this is translated into a request to
	  start all processes (see user_visible_resume_ptid),

	  3. In the linux-nat layer we spot that one of the threads we are
	  about to start is a vfork parent, and so don't start that
	  thread (see resume_lwp), the vfork child thread is resumed,

	  4. GDB waits for the next event, eventually entering
	  linux_nat_target::wait, which in turn calls linux_nat_wait_1,

	  5. In linux_nat_wait_1 we eventually call
	  resume_stopped_resumed_lwps, this should restart threads that have
	  stopped but don't actually have anything interesting to report.

	  6. Unfortunately, resume_stopped_resumed_lwps doesn't check for
	  vfork parents like resume_lwp does, so at this point the vfork
	  parent is resumed.  This feels like the start of the bug, and this
	  is where I'm proposing to fix things, but, resuming the vfork parent
	  isn't the worst thing in the world because....

	  7. As the vfork child is still alive the kernel holds the vfork
	  parent stopped,

	  8. Eventually the child performs its exec and GDB is sent and EXECD
	  event.  However, because the parent is resumed, as soon as the child
	  performs its exec the vfork parent also sends a VFORK_DONE event to
	  GDB,

	  9. Depending on timing both of these events might seem to arrive in
	  GDB at the same time.  Normally GDB expects to see the EXECD or
	  EXITED/SIGNALED event from the vfork child before getting the
	  VFORK_DONE in the parent.  We know this because it is as a result of
	  the EXECD/EXITED/SIGNALED that GDB detaches from the parent (see
	  handle_vfork_child_exec_or_exit for details).  Further the comment
	  in target/waitstatus.h on TARGET_WAITKIND_VFORK_DONE indicates that
	  when we remain attached to the child (not the parent) we should not
	  expect to see a VFORK_DONE,

	  10. If both events arrive at the same time then GDB will randomly
	  choose one event to handle first, in some cases this will be the
	  VFORK_DONE.  As described above, upon seeing a VFORK_DONE GDB
	  expects that (a) the vfork child has finished, however, in this case
	  this is not completely true, the child has finished, but GDB has not
	  processed the event associated with the completion yet, and (b) upon
	  seeing a VFORK_DONE GDB assumes we are remaining attached to the
	  parent, and so resumes the parent process,

	  11. GDB now handles the EXECD event.  In our case we are detaching
	  from the parent, so GDB calls target_detach (see
	  handle_vfork_child_exec_or_exit),

	  12. While this has been going on the vfork parent is executing, and
	  might even exit,

	  13. In linux_nat_target::detach the first thing we do is stop all
	  threads in the process we're detaching from, the result of the stop
	  request will be cached on the lwp_info object,

	  14. In our case the vfork parent has exited though, so when GDB
	  waits for the thread, instead of a stop due to signal, we instead
	  get a thread exited status,

	  15. Later in the detach process we try to resume the threads just
	  prior to making the ptrace call to actually detach (see
	  detach_one_lwp), as part of the process to resume a thread we try to
	  touch some registers within the thread, and before doing this GDB
	  asserts that the thread is stopped,

	  16. An exited thread is not classified as stopped, and so the assert
	  triggers!

	So there's two bugs I see here.  The first, and most critical one here
	is in step #6.  I think that resume_stopped_resumed_lwps should not
	resume a vfork parent, just like resume_lwp doesn't resume a vfork
	parent.

	With this change in place the vfork parent will remain stopped in step
	instead GDB will only see the EXECD/EXITED/SIGNALLED event.  The
	problems in #9 and #10 are therefore skipped and we arrive at #11,
	handling the EXECD event.  As the parent is still stopped #12 doesn't
	apply, and in #13 when we try to stop the process we will see that it
	is already stopped, there's no risk of the vfork parent exiting before
	we get to this point.  And finally, in #15 we are safe to poke the
	process registers because it will not have exited by this point.

	However, I did mention two bugs.

	The second bug I've not yet managed to actually trigger, but I'm
	convinced it must exist: if we forget vforks for a moment, in step #13
	above, when linux_nat_target::detach is called, we first try to stop
	all threads in the process GDB is detaching from.  If we imagine a
	multi-threaded inferior with many threads, and GDB running in non-stop
	mode, then, if the user tries to detach there is a chance that thread
	could exit just as linux_nat_target::detach is entered, in which case
	we should be able to trigger the same assert.

	But, like I said, I've not (yet) managed to trigger this second bug,
	and even if I could, the fix would not belong in this commit, so I'm
	pointing this out just for completeness.

	There's no test included in this commit.  In a couple of commits time
	I will expand gdb.base/foll-vfork.exp which is when this bug would be
	exposed.  Unfortunately there are at least two other bugs (separate
	from the ones discussed above) that need fixing first, these will be
	fixed in the next commits before the gdb.base/foll-vfork.exp test is
	expanded.

	If you do want to reproduce this failure then you will for certainly
	need to run the gdb.base/foll-vfork.exp test in a loop as the failures
	are all very timing sensitive.  I've found that running multiple
	copies in parallel makes the failure more likely to appear, I usually
	run ~6 copies in parallel and expect to see a failure after within
	10mins.

	gdb: catch more errors in gdb.base/foll-vfork.exp
	For *reasons* I was looking at gdb.base/foll-vfork.exp.  This test
	script has a proc 'setup_gdb' that could (potentially) fail.  The
	setup_gdb proc is called from many places and I, initially, didn't
	think that we were checking if setup_gdb had failed or not.

	My confusion was because I didn't understand what this tcl construct
	did:

	  return -code return

	this will actually act as a return in the context of a proc's caller,
	effectively returning two levels of the call stack.  Neat (I guess).

	So it turns out my worries were misplaced, everywhere setup_gdb is
	called, if setup_gdb fails then we will (magically) return.

	However, I did spot one place where we managed to confuse ourselves
	with our cleverness.

	In check_vfork_catchpoints, this proc is called to check that GDB is
	able to catch vforks or not.  This proc is called early in the test
	script, and the intention is that, should this proc fail, we'll mark
	the whole test script as unsupported and then move onto the next test
	script.

	However, check_vfork_catchpoints also uses setup_gdb, and so, if that
	call to setup_gdb fails we'll end up returning immediately from
	check_vfork_catchpoints, and then continue with the test of _this_
	test script, which is not correct.

	To fix this I see two choices, one is remove the use of 'return -code
	return' from setup_gdb, however, this would require every use of
	setup_gdb to then be placed inside:

	  if { ![setup_gdb] } {
	    return
	  }

	Or, I can wrap the one call to setup_gdb in check_vfork_catchpoints
	and check its return code.

	I chose the second option as this is the smaller code change.

	There should be no change in what is tested after this commit.

	idea.  The problem is that you only want to pick up the following
	.plt, not the one preceeding __bss_start in the data segment if the

	gdb: style filenames in separate debug file warnings

	      gdb: defer warnings when loading separate debug files

	It was pointed out[1] that the warnings being deferred and then later
	emitted lacked styling.  The warnings lacked styling before the above
	commit, but it was suggested that the filenames in these warnings
	should be styled, and this commit does this.

	There were a couple of previous attempts[2][3][4] to solve this
	problem, but these all tried to extend the mechanism introduced in the
	above commit, the deferred warnings were placed directly into a
	std::vector, but now we tried to, when appropriate, style these
	warnings.  The review feedback that this approach looked too complex.

	So instead, this revision adds a new helper class 'deferred_warnings'
	which can be used to collect a set of deferred warnings, and then emit
	these deferred warnings later, if needed.  This helper class hides the
	complexity, so at the point the deferred warning is created no extra
	logic is required.

	The deferred_warnings class will style the deferred warnings only if
	gdb_stderr supports styling.  GDB's warnings are sent to gdb_stderr,
	so this should ensure we only style when expected.

	There was also review feedback[5] that all of the warnings should be
	bundled into a single string_file, this has not been done.  I feel
	pretty strongly that separate warnings should be emitted using
	separate "warning" calls.  If we do end up with multiple warnings in
	this case they aren't really related, one will be about looking up
	debug via .gnu_debuglink, while the other will be about build-id based
	lookup.  So I'd really rather keep the warnings separate.

	error message look cryptic. It was reported in bugzilla as PR cli/30497.

	This commit improves the user experience by changing the behavior of

	gdb/cli: add '.' as an argument for 'list' command
	Currently, after the user has used the list command once, there is no
	self-contained way to ask GDB to print the location where the inferior is
	stopped.  The current best options require either using a separate
	command to scope out where the inferior is stopped, or using "list *$pc"
	requiring knowledge of GDB standard registers.  This commit adds a way
	to do that using '.' as a new argument for the 'list' command.  If the
	inferior isn't running, the command prints around the main function.

	Because this necessitated having the inferior running and the test was
	(seemingly unnecessarily) using printf in a non-essential way and it
	would make the resulting log harder to read for no benefit, it was
	replaced by a different statement.

	x86: simplify table-referencing macros
	First of all it is entirely unclear why THREE_BYTE_TABLE_PREFIX() was
	introduced by bf890a93a7c4. Nothing uses the .prefix_requirement values
	from the two relevant entries.

	And then having VEX_Cn_TABLE() and friends take arguments is misleading.
	These aren't used (or pointlessly used in the case of VEX_C5_TABLE); the
	respective table index is decoded from the insn (or implied in the case
	of VEX_C5_TABLE).

	x86: various operations on mask registers can avoid going through mod_table[]
	Now that we have OP_R(), use it here as well, while wiring memory-only
	operands to OP_M() at the same time. To keep the number of consumed
	opcode bytes similar to before, make BadOp() also account for VEX/XOP/
	EVEX prefix bytes. To keep that change simple, convert need_vex to an
	actual count of prefix bytes (keeping intact all prior boolean uses of
	the field).

	Note how this improves disassembly of such bad encodings, by at least
	leaving a hint towards what a "nearby" instruction is. (For KSHIFT*
	change the immediates test testcases use, such that disassembly remains
	sufficiently in sync.)

	While there also use Ux for VPMOV{B,W,D,Q}2M, where decoding through

	x86: slightly rework handling of some register-only insns
	Fold OP_MS() and OP_XS() into OP_R(), paralleling OP_M(). Use operand

	Uxmm though, marking 256-bit forms as bad. This then allows no longer
	going through vex_len_table[] for two of the insns.

	FXSAVE_Fixup() wires through to OP_M(). Note further that OP_IndirE(),
	which wasn't placed very well anyway, is moved down to avoid the need to

	x86: {,V}MOVNT* don't need to go through mod_table[]
	Most of them use Mx already for the memory operand, which rejects the

	forms which so far have used EXEvexXNoBcst (and thus failed to reject
	the register forms), compensating by flagging broadcast as bad for all
	Mx. This way several other insns which don't permit embedded broadcast
	either are also covered at the same time.

	x86: fold legacy/VEX {,V}MOV{H,L}* entries
	By changing decode order to do ModR/M.mod last (rather than VEX.L), the
	VEX entries (which are already reused by EVEX decoding) can be folded
	with their legacy counterparts as well. Note how this change of decode
	order also allows removing two auxiliary #define-s, which were
	introduced during earlier folding (because of that unhelpful order of
	steps).

	x86: fold certain legacy/VEX table entries
	Introduce macro V to expand to 'v' in the VEX/EVEX case, and replace a
	couple of abort()s where legacy code can now legitimately make it. While
	there for {,V}LDDQU drop hoing through mod_table[] - OP_M() rejects
	register operands quite fine.

	      gdbserver: allow agent expressions to fail with invalid memory access

	Now that agent expressions might fail with the error
	expr_eval_invalid_memory_access, we might overflow the
	eval_result_names array in tracepoint.cc.  This is because the
	eval_result_names array does not include a string for either
	expr_eval_invalid_goto or expr_eval_invalid_memory_access.

	I don't know if having expr_eval_invalid_goto missing is also a
	problem, but it feels like eval_result_names should just include a
	string for every possible error.

	I could just add two more strings into the array, but I figure that a
	more robust solution will be to move all of the error types, and their
	associated strings, into a new ax-result-types.def file, and to then
	include this file in both ax.h and tracepoint.cc in order to build
	the enum eval_result_type and the eval_result_names string array.

	gdb/testsuite: avoid stack addresses in test names
	When comparing the test results for two different runs of GDB I
	noticed a difference in the results for gdb.base/frame-view.exp.

	The difference was caused by one of the tests including a stack
	address in the test name:

	  PASS: gdb.base/frame-view.exp: with_pretty_printer=false: select-frame view 0x7ffff7c5cea8 0x40115b

	and

	  PASS: gdb.base/frame-view.exp: with_pretty_printer=true: select-frame view 0x7ffff7c5cea8 0x40115b

	If for whatever reason the stack address changes between test runs
	then it becomes harder to compare results.

	Fix this by giving the test a descriptive name that doesn't include a
	stack address:

	  PASS: gdb.base/frame-view.exp: with_pretty_printer=false: select thread 2 frame from thread 1

	and

	  PASS: gdb.base/frame-view.exp: with_pretty_printer=true: select thread 2 frame from thread 1

	There's no change to what is actually tested after this commit.

	gdb/testsuite: return after reporting a test unsupported
	In this commit:

	  commit 8bcead69665af3a9f9867cd34c3a1daf22120027

	      gdb/testsuite: add test for core file with a 0 pid

	a new test gdb.arch/core-file-pid0.exp was added.  This test includes
	a pre-generated core file for x86-64 and for other architectures the
	test reports 'unsupported'.

	However, after reporting 'unsupported' the test failed to perform an
	early return, so the test would then carry on and try to actually
	perform the test, which resulted in some TCL errors.

	Fix this by returning after reporting the test unsupported.

	gdb: include location number in breakpoint error message
	This commit improves the output of this previous commit:

	  commit 2dc3457a454a35d0617dc1f9cc1db77468471f95

	      gdb: include breakpoint number in testing condition error message

	The earlier commit extended the error message:

	  Error in testing breakpoint condition:

	to include the breakpoint number, e.g.:

	  Error in testing breakpoint condition 3:

	This commit extends takes this further, and includes the location
	number if the breakpoint has multiple locations, so we might now see:

	  Error in testing breakpoint condition 3.2:

	Just as with how GDB reports a normal breakpoint stop, if a breakpoint
	only has a single location then the location number is not included,
	this keeps things nice and consistent.

	I've extended one of the tests to cover the new functionality.

	gdb/testsuite: Testing with the nvfortran compiler
	Currently, the Fortran test suite does not run with NVIDIA's Fortran
	compiler (nvfortran).

	The goal here is to get the tests running and preventing further
	regressions during future work. This change does not do anything to fix
	existing failures.

	Teach the compiler detection about nvfortran. There is no underlying
	information about whether this compiler is related to flang classic or
	flang, so we cannot reuse the main and type definitions. Therefore, we
	explicitly record the main method and type information observed when
	using nvfortran.

	The main name was extracted by trying to set breakpoints on both MAIN_
	and MAIN__.

	The following mapping of test to type names was used to extract how
	nvfortran reports types.

	info-types.exp: fortran_int4, fortran_int8, fortran_real4,
	fortran_logical4

	common-block.exp: fortran_real8

	complex.exp: fortran_complex4 fortran_complex8

	logical.exp: fortran_character1. Ran ptype on "c".

	Types defined as fortran_complex16 do not compile with nvfortran, so it
	was left unset.

	gdb.fortran regression tests run with GNU, Intel, Intel LLVM and ACfL.
	No regressions detected.

	The gdb.fortran test results with nvfortran 23.3 are as follows.

	Before:

	    # of expected passes        523
	    # of unexpected failures    107
	    # of known failures         2
	    # of unresolved testcases   1
	    # of untested testcases     7
	    # of duplicate test names   2

	After:

	    # of expected passes        5696
	    # of unexpected failures    271
	    # of known failures         12
	    # of untested testcases     9
	    # of unsupported tests      5

	As can be seen from the above, there are now considerably more passing
	assertions.

	Remove unchecked casts to mi_interp
	Simon noticed a crash that could be caused via new Python
	gdb.execute_mi function.  Looking into this, I found a few unchecked

	-  struct mi_interp *mi = (struct mi_interp *) command_interp ();

	This patch replaces all such casts with safer variants.

	For -gdb-exit and mi_load_progress, I chose to have the functions
	simply not generate any output.  It didn't seem useful to do so.

	Some casts I eliminated by adding a parameter to a function.  Then, in
	mi_execute_command, I changed the code to use
	gdb::checked_static_cast.  This is appropriate because this particular
	overload can only be called by the MI interpreter.

	There does not seem to be a very good way to test -gdb-exit.

	gdb: check max-value-size when reading strings for printf
	I noticed that the printf code for strings, printf_c_string and
	printf_wide_c_string, don't take max-value-size into account, but do
	load a complete string from the inferior into a GDB buffer.

	As such it would be possible for an badly behaved inferior to cause
	GDB to try and allocate an excessively large buffer, potentially
	crashing GDB, or at least causing GDB to swap lots, which isn't
	great.

	We already have a setting to protect against this sort of thing, the
	'max-value-size'.  So this commit updates the two function mentioned
	above to check the max-value-size and give an error if the
	max-value-size is exceeded.

	If the max-value-size is exceeded, I chose to continue reading
	inferior memory to figure out how long the string actually is, we just
	don't store the results.  The benefit of this is that when we give the
	user an error we can tell the user how big the string actually is,
	which would allow them to correctly adjust max-value-size, if that's
	what they choose to do.

	The default for max-value-size is 64k so there should be no user
	visible changes after this commit, unless the user was previously
	printing very large strings.  If that is the case then the user will
	now need to increase max-value-size.

	gdb: remove last alloca call from printcmd.c
	This commit removes the last alloca call from printcmd.c.  This is
	similar to the patches I originally posted here:

	  https://inbox.sourceware.org/gdb-patches/cover.1677533215.git.aburgess@redhat.com/

	However, this change was not included in that original series.

	The original series received push back because it was thought that
	replacing alloca with a C++ container type would introduce unnecessary
	malloc/free overhead.

	However, in this case we are building a string, and (at least for
	GCC), the std::string type has a small string optimisation, where
	small strings are stored on the stack.

	And in this case we are building what will usually be a very small
	string, we're just constructing a printf format specifier for a hex
	value, so it'll be something like '%#x' -- though it could also have a
	width in there too -- but still, it should normally fit within GCCs
	small string buffer.

	So, in this commit, I propose replacing the use of alloca with a
	std::string.  This shouldn't result (normally) in any additional
	malloc or free calls, so should be similar in performance to the
	original approach.

	There should be no user visible differences after this commit.

	gdb: remove two uses of alloca from printcmd.c
	Remove a couple of uses of alloca from printcmd.c, and replace them
	with gdb::byte_vector.

	An earlier variant of this patch was proposed in this thread:

	  https://inbox.sourceware.org/gdb-patches/cover.1677533215.git.aburgess@redhat.com/

	however, there was push back on that thread due to it adding extra
	dynamic allocation, i.e. moving the memory buffers off the stack on to
	the heap.

	However, of all the patches originally proposed, I think in these two
	cases moving off the stack is the correct thing to do.  Unlike all the
	other patches in the original series, where the data being read
	was (mostly) small in size, a register, or a couple of registers, in
	this case we are reading an arbitrary string from the inferior.  This
	could be any size, and so should not be placed on the stack.

	So in this commit I replace the use of alloca with std::byte_vector
	and simplify the logic a little (I think) to take advantage of the
	ability of std::byte_vector to dynamically grow in size.

	Of course, really, we should probably be checking the max-value-size
	setting as we load the string to stop GDB crashing if a corrupted
	inferior causes GDB to try read a stupidly large amount of
	memory... but I'm leaving that for a follow on patch.

	There should be no user visible changes after this commit.

	gdb: fix printf of wchar_t early in a gdb session
	Given this test program:

	  #include <wchar.h>

	  const wchar_t wide_str[] = L"wide string";

	  int
	  main (void)
	  {
	    return 0;
	  }

	I observed this GDB behaviour:

	  $ gdb -q /tmp/printf-wchar_t
	  Reading symbols from /tmp/printf-wchar_t...
	  (gdb) start
	  Temporary breakpoint 1 at 0x40110a: file /tmp/printf-wchar_t.c, line 8.
	  Starting program: /tmp/printf-wchar_t

	  Temporary breakpoint 1, main () at /tmp/printf-wchar_t.c:8
	  25	  return 0;
	  (gdb) printf "%ls\n", wide_str

	  (gdb)

	Notice that the printf results in a blank line rather than the
	expected 'wide string' output.

	I tracked the problem down to printf_wide_c_string (in printcmd.c), in
	this function we do this:

	  struct type *wctype = lookup_typename (current_language,
						 "wchar_t", NULL, 0);
	  int wcwidth = wctype->length ();

	the problem here is that 'wchar_t' is a typedef.  If we look at the
	comment on type::length() we see this:

	  /* Note that if thistype is a TYPEDEF type, you have to call check_typedef.
	     But check_typedef does set the TYPE_LENGTH of the TYPEDEF type,
	     so you only have to call check_typedef once.  Since value::allocate
	     calls check_typedef, X->type ()->length () is safe.  */

	What this means is that after calling lookup_typename we should call
	check_typedef in order to ensure that the length of the typedef has
	been setup correctly.  We are not doing this in printf_wide_c_string,
	and so wcwidth is incorrectly calculated as 0.  This is what leads GDB
	to print an empty string.

	We can see in c_string_operation::evaluate (in c-lang.c) an example of
	calling check_typedef specifically to fix this exact issue.

	Initially I did fix this problem by adding a check_typedef call into
	printf_wide_c_string, but then I figured why not move the
	check_typedef call up into lookup_typename itself, that feels like it
	should be harmless when looking up a non-typedef type, but will avoid
	bugs like this when looking up a typedef.  So that's what I did.

	I can then remove the extra check_typedef call from c-lang.c, I don't
	see any other places where we had extra check_typedef calls.  This
	doesn't mean we definitely had bugs -- so long as we never checked the
	length, or, if we knew that check_typedef had already been called,
	then we would be fine.

	I don't see any test regressions after this change, and my new test
	case is now passing.

	Linux: Avoid pread64/pwrite64 for high memory addresses (PR gdb/30525)
	Since commit 05c06f318fd9 ("Linux: Access memory even if threads are
	running"), GDB prefers pread64/pwrite64 to access inferior memory
	instead of ptrace.  That change broke reading shared libraries on
	SPARC64 Linux, as reported by PR gdb/30525 ("gdb cannot read shared
	libraries on SPARC64").

	On SPARC64 Linux, surprisingly (to me), userspace shared libraries are
	mapped at high 64-bit addresses:

	   (gdb) info sharedlibrary
	   Cannot access memory at address 0xfff80001002011e0
	   Cannot access memory at address 0xfff80001002011d8
	   Cannot access memory at address 0xfff80001002011d8
	   From                To                  Syms Read   Shared Object Library
	   0xfff80001000010a0  0xfff8000100021f80  Yes (*)     /lib64/ld-linux.so.2
	   (*): Shared library is missing debugging information.

	Those addresses are 64-bit addresses with the high bits set.  When
	interpreted as signed, they're negative.

	The Linux kernel rejects pread64/pwrite64 if the offset argument of
	type off_t (a signed type) is negative, which happens if the memory
	address we're accessing has its high bit set.  See
	linux/fs/read_write.c sys_pread64 and sys_pwrite64 in Linux.

	Thankfully, lseek does not fail in that situation.  So the fix is to
	use the 'lseek + read|write' path if the offset would be negative.

	Fix this in both native GDB and GDBserver.

	Tested on a SPARC64 GNU/Linux and x86-64 GNU/Linux.

	 A problem internal to GDB has been detected,
	 further debugging may prove unreliable.
	 Quit this debugging session? (y or n)

	The backtrace, after running it through c++filt, looks like:

		 /root/binutils-gdb/gdb/target.c:2586
	 ...

	The problem is that the procfs backend, while inside target_wait,
	called target_resume without switching to the leader thread of that
	resumption.

	The target_resume interface is:

	 /* Resume execution (or prepare for execution) of the current thread
	    (INFERIOR_PTID), while optionally letting other threads of the
	    current process or all processes run free.
	    ...

	Thus calling target_resume with inferior_ptid == null_ptid is bogus.

	target_wait (which leads to procfs_target::wait on Solaris) is called
	with inferior_ptid == null_ptid on entry exactly to help catch such
	bogus uses.

	From the backtrace, it seems that the relevant line in question is
	procfs.c:2187:

	2186  /* How to keep going without returning to wfi: */
	2187  target_continue_no_signal (ptid);
	2188  goto wait_again;

	target_continue_no_signal is a small wrapper around target_resume,
	which would make sense.

	The fix is to not call target_resume or go via the target stack at
	all.  Instead, factor out a new proc_resume function out of
	procfs_target::resume, and call that.  The new function does not rely
	on inferior_ptid.

	I've not been able to test it myself, but Petr confirmed it fixes the
	assertion failure with his test case, and Marcel Telka also confirmed
	it solves the problem.

	ld: fix plugin tests for MIPS PIC
	On MIPS, for PIC objects, symbols may reference 2 times:
	once from the caller, and once from GOT.
	Thus ld may complains 2 times about "undefined reference".

	So we add a new "#?" line to every effected testsuite.

	Use run_host_cmd to run $CC and other no-section-header test fixes
	We should be using run_host_cmd everywhere we invoke a compiler in the
	ld testsuite, if we want to use ld/ld-new just built.  run_host_cmd
	properly inserts $gcc_B_opt in cases where a user wants to test
	binutils with a newly built compiler, ie. when $CC specifies -B itself.

	Also, it is not good practice to exclude tests when non-native except
	of course those tests that run a target binary.  Compiling and linking
	often shows up problems.

		* testsuite/ld-elf/no-section-header.exp (binutils_run_test):
		Use run_host_cmd to invoke $CC_FOR_TARGET.  Run all tests
		non-native too, except for attempting to run the binaries.
		Run tests for ELF in general, not just linux.

	gdb: add __repr__() implementation to a few Python types
	Only a few types in the Python API currently have __repr__()
	implementations.  This patch adds a few more of them. specifically: it
	adds __repr__() implementations to gdb.Symbol, gdb.Architecture,
	gdb.Block, gdb.Breakpoint, gdb.BreakpointLocation, and gdb.Type.

	This makes it easier to play around the GDB Python API in the Python
	interpreter session invoked with the 'pi' command in GDB, giving more
	easily accessible tipe information to users.

	An example of how this would look like:

	  (gdb) pi
	  >> gdb.lookup_type("char")
	  <gdb.Type code=TYPE_CODE_INT name=char>
	  >> gdb.lookup_global_symbol("main")
	  <gdb.Symbol print_name=main>

	The gdb.Block.__repr__() method shows the first 5 symbols from the
	block, and then a message to show how many more were elided (if any).

	gdb: have mdict_size always return a symbol count
	In the next commit we would like to have mdict_size return the number
	of symbols in the dictionary, currently mdict_size is just a
	heuristic, sometimes it returns the number of symbols, and sometimes
	the number of buckets in a hashing dictionary (see size_hashed in
	dictionary.c).

	Currently this vague notion of size is good enough, the only place
	mdict_size is used is in a maintenance command in order to print a
	message containing the size of the dictionary ... so we don't really
	care that the value isn't correct.

	However, in the next commit we do want the size returned to be the
	number of symbols in the dictionary, so this commit makes mdict_size
	return the symbol count in all cases.

	The new use is still not on a hot path -- it's going to be a Python
	__repr__ method, so all I do in this commit is have size_hashed walk
	the dictionary and count the entries, obviously this could be slow if
	we have a large number of symbols, but for now I'm not worrying about
	that case.  We could always store the symbol count if we wanted, but
	that would increase the size of every dictionary for a use case that
	isn't going to be hit that often.

	I've updated the text in 'maint print symbols' so that we don't talk
	about the size being 'syms/buckets', but just 'symbols' now.

	IBM Z: Fix pcrel relocs for symA-symB expressions
	The code in md_apply_fix which tries to deduce from the operand type
	which reloc to apply currently does the wrong thing for absolute
	relocs which have been re-written by fixup_segment as pc-relative to
	implement a subtraction of a local and an external symbol.

	In all these cases we wrongly emit an absolute reloc because we ignore
	the fx_pcrel flag in md_apply_fix. However, only for the last one we
	actually support a pc relative relocation of the proper size and can
	implement it accordingly. For the other 3 we have to issue an error.

	gdb: handle core files with .reg/0 section names
	The previous commit added the test gdb.arch/core-file-pid0.exp which
	tests GDB's ability to load a core file containing threads with an
	lwpid of 0, which is something we GDB can encounter when loading a
	vmcore file -- a core file generated by the Linux kernel.  The threads
	with an lwpid of 0 represents idle cores.

	While the previous commit added the test, which confirms GDB doesn't
	crash when confronted with such a core file, there are still some
	problems with GDB's handling of these core files.  These problems all
	originate from the fact that the core file (once opened by bfd)
	contains multiple sections called .reg/0, these sections all
	represents different threads (cpu cores in the original vmcore dump),
	but GDB gets confused and thinks all of these .reg/0 sections are all
	referencing the same thread.

	Here is a GDB session on an x86-64 machine which loads the core file
	from the gdb.arch/core-file-pid0.exp, this core file contains two
	threads, both of which have a pid of 0:

	  $ ./gdb/gdb --data-directory ./gdb/data-directory/ -q
	  (gdb) core-file /tmp/x86_64-pid0-core.core

	Notice when the core file is first loaded we see two lines like:

	  [New process 1]

	And GDB reports:

	  The current thread has terminated

	Which isn't what we'd expect from a core file -- the core file should
	only contain threads that are live at the point of the crash, one of
	which should be the current thread.  The above message is reported
	because GDB has deleted what we think is the current thread!

	And in the 'info threads' output we are only seeing a single thread,
	again, this is because GDB has deleted one of the threads.

	Finally, the 'maintenance info sections' output shows the cause of all
	our problems, two sections named .reg/0.  When GDB sees the first of
	these it creates a new thread.  But, when we see the second .reg/0 GDB
	tries to create another new thread, but this thread has the same
	ptid_t as the first thread, so GDB deletes the first thread and
	creates the second thread in its place.

	Because both these threads are created with an lwpid of 0 GDB reports
	these are 'New process NN' rather than 'New LWP NN' which is what we
	would normally expect.

	The previous commit includes a little more of the history of GDB
	support in this area, but these problems were discussed on the mailing
	list a while ago in this thread:

	  https://inbox.sourceware.org/gdb-patches/AANLkTi=zuEDw6qiZ1jRatkdwHO99xF2Qu+WZ7i0EQjef@mail.gmail.com/

	In this commit I propose a solution to these problems.

	What I propose is that GDB should spot when we have .reg/0 sections
	and, when these are found, should rename these sections using some
	unique non-zero lwpid.

	Note in the above output we also have sections like .reg2/0 and
	.reg-xstate/0, these are additional register sets, this commit also
	renumbers these sections inline with their .reg section.

	The user is warned that some section renumbering has been performed.

	GDB takes care to ensure that the new numbers assigned are unique and
	don't clash with any of the pid's that might already be in use --
	remember, in a real vmcore file, 0 is used to indicate an idle core,
	non-idle cores will have the pid of whichever process was running on
	that core, so we don't want GDB to assign an lwpid that clashes with
	an actual pid that is in use in the core file.

	After this commit here's the updated GDB session output:

	  $ ./gdb/gdb --data-directory ./gdb/data-directory/ -q
	  (gdb) core-file /tmp/x86_64-pid0-core.core

	Notice the new warning which is issued when the core file is being
	loaded.  The threads are announced as '[New LWP NN]', and we see two
	threads in the 'info threads' output.  The 'maintenance info sections'
	output shows the result of the section renaming.

	The gdb.arch/core-file-pid0.exp test has been update to check for the
	improved GDB output.

	gdb/testsuite: add test for core file with a 0 pid
	This patch contains a test for this commit:

	  commit c820c52a914cc9d7c63cb41ad396f4ddffff2196
	  Date:   Fri Aug 6 19:45:58 2010 +0000

	              * thread.c (add_thread_silent): Use null_ptid instead of
	              minus_one_ptid while getting rid of stale inferior_ptid.

	This is another test that has been carried in the Fedora GDB tree for
	some time, and I thought that it would be worth merging to master.  I
	don't believe there is any test like this currently in the testsuite.

	The original issue was reported in this thread:

	  https://inbox.sourceware.org/gdb-patches/AANLkTi=zuEDw6qiZ1jRatkdwHO99xF2Qu+WZ7i0EQjef@mail.gmail.com/

	The problem was that when GDB was used to open a vmcore (core file)
	image generated by the Linux kernel GDB would (sometimes) crash with
	an assertion failure:

	  thread.c:884: internal-error: switch_to_thread: Assertion `inf != NULL' failed.

	To understand what's going on we need some background; a vmcore file
	represents each processor core in the same way that a standard
	application core file represents threads.  Thus, we might say, a
	vmcore file represents cores as threads.

	When writing a vmcore file, the kernel will store the pid of the
	process currently running on that core as the thread's lwpid.

	However, if a core is idle, with no process currently running on it,
	then the lwpid for that thread is stored as 0 in the vmcore file.  If
	multiple cores are idle then multiple threads will have a lwpid of 0.

	Back in 2010, the original issue reported tried to change the kernel's
	behaviour in this thread:

	  https://lkml.org/lkml/2010/8/3/75

	This change was rejected by the kernel team, the current
	behaviour (lwpid of 0) was considered correct.  I've checked the
	source of a recent kernel.  The code mentioned in the lkml.org posting
	has moved, it's now in the function crash_save_cpu in the file
	kernel/kexec_core.c, but the general behaviour is unchanged, an idle
	core will have an lwpid of 0, so I think GDB still needs to be able to
	handle this case.

	When GDB loads a vmcore file (which is handled just like any other
	core file) the sections are processed in core_open to generate the
	threads for the core file.  The processing is done by calling
	add_to_thread_list, a function which looks for sections named .reg/NN
	where NN is the lwpid of the thread, GDB then builds a ptid_t for the
	new thread and calls add_thread.

	Remember, in our case the lwpid is 0.  Now for the first thread this
	is fine, if a little weird, 0 isn't usually a valid lwpid, but that's
	OK, GDB creates a thread with lwpid of 0 and carries on.

	When we find the next thread (core) with lwpid of 0, we attempt to
	create another thread with an lwpid of 0.  This of course clashes with
	the previously created thread, they have the same ptid_t, so GDB tries
	to delete the first thread.

	And it was within this thread delete code that we triggered a bug
	which would then cause GDB to assert -- when deleting we tried to
	switch to a thread with minus_one_ptid, this resulted in a call to
	find_inferior_pid (passing in minus_one_ptid's pid, which is -1), the
	find_inferior_pid call fails and returns NULL, which then triggered an
	assert in switch_to_thread.

	The actual details of the why the assert triggered are really not
	important.  What's important (I think) is that a vmcore file might
	have this interesting lwpid of 0 characteristic, which isn't something
	we see in "normal" application core files, and it is this that I think
	we should be testing.

	Now, you might be thinking: isn't deleting the first thread the wrong
	thing to do?  If the vmcore file has two threads that represent two
	cores, and both have an lwpid of 0 (indicating both cores are idle),
	then surely GDB should still represent this as two threads?  You're
	not wrong.  This was mentioned by Pedro in the original GDB mailing
	list thread here:

	  https://inbox.sourceware.org/gdb-patches/201008061057.03037.pedro@codesourcery.com/

	This is indeed a problem, and this problem is still present in GDB
	today.  I plan to try and address this in a later commit, however,
	this first commit is about getting a test in place to confirm that GDB
	at a minimum doesn't crash when loading such a vmcore file.

	And so, finally, what's in this commit?

	This commit contains a new test.  The test doesn't actually contain a
	vmcore file.  Instead I've created a standard application core file
	that contains two threads, and then manually edited the core file to
	set the lwpid of each thread to 0.

	To further reduce the size of the core file (as it will be stored in
	git), I've zeroed all of the LOAD-able segments in the core file.
	This test really doesn't care about that part of the core file, we
	only really care about loading the register's, this is enough to
	confirm that the GDB doesn't crash.

	Obviously as the core file is pre-generated, this test is architecture
	specific.  There are already a few tests in gdb.arch/ that include
	pre-generate core files.  Just as those existing tests do, I've
	compressed the core file with bzip2, which reduces it to just 750
	bytes.  I have structured the test so that if/when this patch is
	merged I can add some additional core files for other architectures,
	however, these are not included in this commit.

	The test simply expands the core file, and then loads it into GDB.
	One interesting thing to note is that GDB reports the core file
	loading like this:

	  (gdb) core-file ./gdb/testsuite/outputs/gdb.arch/core-file-pid0/core-file-pid0.x86-64.core
	  [New process 1]
	  [New process 1]
	  Failed to read a valid object file image from memory.
	  Core was generated by `./segv-mt'.
	  Program terminated with signal SIGSEGV, Segmentation fault.
	  The current thread has terminated
	  (gdb)

	There's two interesting things here: first, the repeated "New process
	1" message.  This is caused because linux_core_pid_to_str reports
	anything with an lwpid of 0 as a process, rather than an LWP.  And
	second, the "The current thread has terminated" message.  This is
	because the first thread in the core file is the current thread, but
	when GDB loads the second thread (which also has lwpid 0) this causes
	the first thread to be deleted, as a result GDB thinks that the
	current (first) thread has terminated.

	As I said previously, both of these problems are a result of the lwpid
	0 aliasing, which is not being fixed in this commit -- this commit is
	just confirming that GDB doesn't crash when loading this core file.

	gdb: split inferior and thread setup when opening a core file
	I noticed that in corelow.c, when a core file is opened, both the
	thread and inferior setup is done in add_to_thread_list.  In this
	patch I propose hoisting the inferior setup out of add_to_thread_list
	into core_target_open.

	The only thing about this change that gave me cause for concern is
	that in add_to_thread_list, we only setup the inferior after finding
	the first section with a name like ".reg/NN".  If we find no such
	section then the inferior will never be setup.

	Is this important?

	Well, I don't think so.  Back in core_target_open, if there is no
	current thread (which there will not be if no ".reg/NN" section was
	found), then we look for a thread in the current inferior.  If there
	are no threads (which there will not be if no ".reg/NN" is found),
	then we once again setup the current inferior.

	What I think this means, is that, in all cases, the current inferior
	will end up being setup.  By moving the inferior setup code earlier in
	core_target_open and making it non-conditional, we can remove the
	later code that sets up the inferior, we now know this will always
	have been done.

	There should be no user visible changes after this commit.

	binutils: NEWS: announce new RISC-V extensions
	We picked up support for a few new extensions over the last weeks
	(this may need further updating prior to the next release), list them
	in the NEWS file.

	binutils/ChangeLog:

		* binutils/NEWS: announce suuport for the new RISC-V
	          extensions (Zicond, Zfa, XVentanaCondOps).

2023-06-30  Christoph Müllner  <christoph.muellner@vrull.eu>

	RISC-V: Add support for the Zfa extension
	This patch adds support for the RISC-V Zfa extension,
	which introduces additional floating-point instructions:
	* fli (load-immediate) with pre-defined immediates
	* fminm/fmaxm (like fmin/fmax but with different NaN behaviour)
	* fround/froundmx (round to integer)
	* fcvtmod.w.d (Modular Convert-to-Integer)
	* fmv* to access high bits of FP registers in case XLEN < FLEN
	* fleq/fltq (quiet comparison instructions)

	Zfa defines its instructions in combination with the following
	extensions:
	* single-precision floating-point (F)
	* double-precision floating-point (D)
	* quad-precision floating-point (Q)
	* half-precision floating-point (Zfh)

	This patch is based on an earlier version from Tsukasa OI:
	  https://sourceware.org/pipermail/binutils/2022-September/122939.html
	Most significant change to that commit is the switch from the rs1-field
	value to the actual floating-point value in the last operand of the fli*
	instructions. Everything that strtof() can parse is accepted and
	the '%a' printf specifier is used to output hex floating-point literals
	in the disassembly.

	The Zfa specification is frozen (and has passed public review).  It is
	available as a chapter in "The RISC-V Instruction Set Manual: Volume 1":
	  https://github.com/riscv/riscv-isa-manual/releases

	LoongArch: Deprecate $v[01], $fv[01] and $x names per spec
	As outlined in the LoongArch ELF psABI spec [1], it is actually already
	2 versions after the initial LoongArch support, and the $v[01] and
	$fv[01] names should really get sunset by now.

	In addition, the "$x" name for $r21 was never included in any released
	version of the ABI spec, and such usages are all fixed to say just $r21
	for every project I could think of that accepted a LoongArch port.

	Plus, the upcoming LSX/LASX support makes use of registers named
	"$vrNN" and "$xrNN", so having "$vN" and "$x" alongside would almost
	certainly create confusion for developers.

	Issue warnings for such usages per the deprecation procedure detailed
	in the spec, so we can finally remove support in the next release cycle
	after this.

	Precisely how one approaches the original use case is not taken care of

	LoongArch: support disassembling certain pseudo-instructions
	Add a flag in the pinfo field for being able to mark certain specialized
	matchers as disassembler-only, so some degree of isolation between
	assembler-side and disassembler-side can be achieved.

	This isolation is necessary, firstly because some pseudo-instructions
	cannot be fully described in the opcode table, like `li.[wd]`, so the
	corresponding opcode entry cannot have meaningful match/mask values.
	Secondly, some of these pseudo-instructions can be realized in more than
	one plausible ways; e.g. `li.w rd, <something between 0 and 0x7ff>` can
	be realized on LA64 with any of `addi.w`, `addi.d` or `ori`. If we tie
	disassembly of such aliases with the corresponding GAS support, only one
	canonical form among the above would be recognized as `li.w`, and it
	would mildly impact the readability of disassembly output.
	People wanting the exact disassembly can always set `-M no-aliases` to
	get the original behavior back.

	In addition, in certain cases, information is irreversibly lost after
	assembling, so perfect round-trip would not be possible in such cases.
	For example, `li.w` and `li.d` of immediates within int32_t range
	produce the same code; in this patch, `addi.d rd, $zero, imm` is treated
	as `li.d`, while `addi.w` and `ori` immediate loads are shown as `li.w`,
	due to the expressible value range well within 32 bits.

2023-06-30  Indu Bhagat  <indu.bhagat@oracle.com>

	doc: sframe: update specification for SFRAME_VERSION_2
	Add details for the changes made from Version 1 to Version 2 of the format.

	Also add details about alignment in the SFrame format.  A portion of the
	SFrame stack trace format has an unaligned on-disk representation.  Add
	description at relevant points in the specificatin to clarify the
	alignment related details.

2023-06-30  Indu Bhagat  <indu.bhagat@oracle.com>

	sframe: bfd: gas: ld: format bump to SFrame version 2
	SFrame version 2 encodes the size of repetitive insn block explicitly
	in the format.  Add information in the SFrame FDE to convey the size
	of the block of repeating instructions.  This information is used only
	for SFrame FDEs of type SFRAME_FDE_TYPE_PCMASK.

	Introduce two extra bytes for padding: this ensures that the memory
	accesses to the members of the SFrame Frame Descriptor Entry (FDE) are
	naturally aligned.

	gas generates SFrame section with version SFRAME_VERSION_2 by default.

	libsframe provides two new APIs to:
	  - get an SFrame FDE data from the decoder context, and
	  - add an SFrame FDE to the encoder context.
	The additional argument (for rep_block_size) is useful for SFrame FDEs
	where FDE type is SFRAME_FDE_TYPE_PCMASK.

	The linker will generate the output SFrame sections in the
	SFRAME_VERSION_2 format.  If the input sections offered to the linker
	are not all in the SFRAME_VERSION_2 format, the linker issues an error
	to the user.

	objdump/readelf will show the following message to the user if .sframe
	section in SFRAME_VERSION_1 format is seen:

	 "No further information can be displayed.  SFrame version not
	 supported."

	In other words, like the rest of the binutils, only the current SFrame

	libsframe: fix sframe_find_fre for pltN entries
	For a toy application on x86_64, for example, following is the SFrame
	stack trace information for the 3 pltN entries of 16 bytes each:

	   func idx [1]: pc = 0x401030, size = 48 bytes
	   STARTPC[m]      CFA       FP        RA
	   0000000000000000  sp+8      u         u
	   000000000000000b  sp+16     u         u

	The data in first column is the start_ip_offset.  Also note that the FDE
	is of type SFRAME_FDE_TYPE_PCMASK (denoted by the [m] on LHS).

	Where each pltN (note: excluding plt0 entry) entry looks like:

	  401030: jmp    *0x2fca(%rip)
	  401036: push   $0x0
	  40103b: jmp    401020<_init+0x20>

	  401040: jmp    *0x2fc2(%rip)
	  401046: push   $0x1
	  40104b: jmp    401020<_init+0x20>

	  401050: jmp    *0x2fba(%rip)
	  401056: push   $0x2
	  40105b: jmp    401020<_init+0x20>

	Now, to find SFrame stack trace information from an FDE of type
	SFRAME_FDE_TYPE_PCMASK, sframe_find_fre () was doing an operation
	like,
	  (start_ip_offset & 0xf) >= (pc & 0xf)

	This works for pltN entry of size, say, less than 16 bytes.  But if the
	pltN entries or similar code stubs (for which SFrame FDE of type
	SFRAME_FDE_TYPE_PCMASK may be used), evolve to be of size > 16 bytes,
	this will cease to work.

	To match the range covered by the SFrame FRE, one should instead perform
	a modulo operation.  The constant for the modulo operation must be the
	size of the pltN entry.  Further, this constant should ideally be
	encoded in the format, as it may be different for each ABI.

	In SFrame Version 2 of the format, we will move towards encoding it
	explicitly in the SFrame FDE.  For now, fix up the logic to at least
	move towards modulo operation.

	bfd: Improve nm and objdump without section header
	When there is no section header in an executable or shared library, we
	reconstruct dynamic symbol table from the PT_DYNAMIC segment, which
	contains DT_HASH/DT_GNU_HASH/DT_MIPS_XHASH, DT_STRTAB, DT_SYMTAB,
	DT_STRSZ, and DT_SYMENT entries, to improve nm and objdump.  For DT_HASH,
	the number of dynamic symbol table entries equals the number of chains.
	For DT_GNU_HASH/DT_MIPS_XHASH, only defined symbols with non-STB_LOCAL
	indings are in hash table.  Since DT_GNU_HASH/DT_MIPS_XHASH place all
	symbols with STB_LOCAL binding before symbols with other bindings and
	all undefined symbols defined ones in dynamic symbol table, the highest
	symbol index in DT_GNU_HASH/DT_MIPS_XHASH is the highest dynamic symbol
	table index.  We can also get symbol version from DT_VERSYM, DT_VERDEF
	and DT_VERNEED entries.

	dt_symtab, dt_versym, dt_verdef, dt_verneed, dt_symtab_count,
	dt_verdef_count, dt_verneed_count and dt_strtab are added to

	Fix handling of DW_TAG_unspecified_type for Ada
	Commit 80eaec735e ("[gdb/symtab] Handle named DW_TAG_unspecified_type
	DIE") changed the handling of DW_TAG_unspecified_type.  Before this
	change, such types were not entered into the symbol table.

	It turns out that, when such a type is in the symtab, it can cause
	failures in Ada.  In particular, a private type in another package may
	be seen locally as "void".

	Now, it would probably be better to fix this via check_typedef.
	However, that is somewhat difficult given the state of the DWARF
	reader -- in particular with gdb_index, this would require expanding
	potentially many CUs to find the correct type.

	Instead, this patch changes gdb to not enter a symbol for an
	unspecified type -- but only for Ada.

	libsframe: update the semantics of sframe_fre_get_fp_offset
	Until now, sframe_fre_get_fp_offset () would return
	SFRAME_ERR_FREOFFSET_NOPRESENT if the ABI uses fixed FP offset.  A stack
	tracer, then, would call an explicit sframe_decoder_get_fixed_fp_offset ()
	to get the FP offset.

	On second look, it appears to make sense to hide these details of
	whether the FP offset is fixed or not in an ABI from the consumer.  Now,
	with the changed semantics, the call to sframe_fre_get_fp_offset () will
	fetch the fixed FP offset if applicable, or get the FP offset from FRE
	when there is no fixed FP offset.

	This patch changes the behavior of sframe_fre_get_fp_offset (): it turns

	libsframe: update the semantics of sframe_fre_get_ra_offset
	Until now, sframe_fre_get_ra_offset () would return
	SFRAME_ERR_FREOFFSET_NOPRESENT if the ABI uses fixed RA offset (e.g.,
	AMD64).  A stack tracer, then, will call an explicit
	sframe_decoder_get_fixed_ra_offset () to get the RA offset.

	On second look, it appears to make sense to hide these details of
	whether the RA offset is fixed or not from the consumer.  Now, with the
	changed semantics, the call to sframe_fre_get_ra_offset () will fetch
	the fixed RA offset if applicable, or get the RA offset from FRE when
	there is no fixed RA offset.

	Adjustments need to be made to ensure the textual dump remains the same
	as preivous.  Currently, e.g., if RA is not being tracked per FRE,
	following is seen with objdump --sframe:

	    STARTPC         CFA       FP        RA

	This patch changes the behavior of sframe_fre_get_ra_offset: it turns an
	error into non-error.  This change will be included with the next
	release of libsframe, where all exposed symbols will be versioned for
	the first time.

	libsframe/
		* sframe.c (sframe_fre_get_ra_offset): Return the fixed offset,
		if applicable.  Else return the RA offset from the FRE.
		* sframe-dump.c (dump_sframe_func_with_fres): Make adjustments
		to keep the textual dump same as previous.

	libsframe: add symbol versioning
	Define an empty base version LIBSFRAME_0.0 and add all symbols to
	version LIBSFRAME_1.0.

	The previous release of libsframe (libsframe.so.0) did not have
	versioned symbols.  Adding a libsframe.ver file so that future releases
	of the library (and its consumers) can manage the changes better.

	For Solaris ld, use -M mapfile command line option.  libsframe does not
	restrict the set of exported symbols, so at this time there is no need
	to fall back on the libtool's -export-symbols option for platforms where
	some other linker (with a different command line option for symbol
	versioning) may be used.

		* Makefile.am: Use symbol versioning for libsframe.
		* Makefile.in: Regenerated.
		* configure: Check for Solaris ld.
		* configure.ac: Regenerated.

	libsframe: remove sframe_get_funcdesc_with_addr API
	This is an incompatible ABI change in libsframe.

	The interface provided by this function is not a healthy abstraction to
	expose: the return type sframe_func_desc_entry, which is defined in
	include/sframe.h (the SFrame binary format definition).  This ties up
	the library in a undesirable way.  Most importantly, this function
	should technically not be directly necessary for a stack tracer.  A
	stack tracer will likely only need to do a sframe_find_fre ().

	Rename the API to continue to use the functionality internally in the
	library.  bfd/linker does not use this function.

	Change the return type of the previous definition and make a note about
	its planned deprecation.

	include/
		* sframe-api.h:  Change return type of sframe_get_funcdesc_with_addr.
		Add comment for intention to deprecate.
	libsframe/
		*sframe.c (sframe_get_funcdesc_with_addr): Change return type
		and set error code. This API is deprecated.
	        (sframe_get_funcdesc_with_addr_internal): New definition for
		internal use.
		(sframe_find_fre): Use sframe_get_funcdesc_with_addr_internal
		instead.

	libsframe: add library versioning

	 - Deprecation of some APIs, like sframe_get_funcdesc_with_addr (), and
	 - Change in the contract of some APIs (e.g., return type, behavior).

	gdb/testsuite: Avoid infinite loop in gdb.reverse/step-reverse.exp
	This testcase sometimes gets stuck in a loop for hours when running in our
	CI.  The problem is that due to an issue unrelated to reverse debugging the
	inferior exits early, and because of the overly generic ".*" pattern the
	testcase keeps sending the "next" command without noticing that the
	inferior is gone.

	gdb_test_multiple has a pattern to detect that "The program is not being
	run.", but since it is placed after the patterns from the caller it won't
	be triggered.  It also has a timeout pattern but because it is triggered
	between successful matches, each time the test matches the '-re -wrap ".*"'
	this counts as a successful match and the timeout is reset.

	Since the test binary is compiled with debug information, fix by changing
	one of the generic patterns to match entering the main function and the
	other one to match the source code line number that is shown by GDB right
	after the "step" command.

	Also, as a precaution add a maximum number of times the "next" command will
	be sent.

	[GOLD] PowerPC64 huge branch dynamic relocs
	PowerPC64 gold and ld.bfd implement an indirect branch trampoline,
	used when the destination of a branch exceeds a bounce through another
	"b" instruction.  When generating PIEs or shared libraries, the
	addresses need dynamic relocations.  This was implemented in gold
	using a dedicated relocation section, but this means the relative
	relocations for these addresses are not sorted properly with other
	dynamic relative relocations: gold doesn't support merging relocation
	sections, then sorting.  Instead we need to use a single .rela.dyn
	section.

	This is done by increasing the size of rela_dyn_ during do_relax to
	account for needed dynamic relocations, delaying adding the actual
	relocations until the end of relaxation once the layout has
	stabilised.

		* powerpc.cc (Target_powerpc): Add rela_dyn_size_;
		(update_current_size): New function.
		(Target_powerpc::do_relax): Capture the size of rela_dyn_ at
		the start of relaxation.  Artifically increase its size during

		those relocations at the end.
		(Output_data_brlt_powerpc::rel_, reset_brlt_sizes),

	DT_RELACOUNT at the point where .dynamic is written.

		parameter.  Emit DT_RELCOUNT/RELACOUNT as a custom target handled
		dynamic tag if set.

	[gdb/testsuite] Clean or check standard_output_file dir in gdb_init
	In commit e2adba909e7 ("[gdb/testsuite] Clean up before compilation in
	gdb.ada/call-no-debug.exp") I added some code in the test-case to remove some
	files at the start of the test-case:
	...
	remote_file host delete [standard_output_file prog.o]
	remote_file host delete [standard_output_file prog.ali]
	...

	Then in commit b7b77500dc5 ("[gdb/testsuite] Clean standard_output_file dir in
	gdb_init") I tried to do this more structurally, by cleaning up the entire
	standard_output_file directory, for all test-cases.

	This caused a regression when using "make check -j 2", due to the cleanup
	removing the active gdb.log, so I reverted the commit.

	Try again, this time handling the two cases separately.

	If the standard_output_file directory contains an active gdb.log, check that
	the directory contains no files other than gdb.log and gdb.sum.  This puts
	the reponsibility for the cleanup at the callers in gdb/testsuite/Makefile.in
	which use --outdir.

	If the standard_output_file directory doesn't contain an active gdb.log, clean
	it by removing the entire directory.

	An exception is made for performance tests, where cleaning up the
	standard_output_file dir is the wrong thing to do, because an invocation with
	GDB_PERFTEST_MODE == run is intended to reuse binaries left there by an
	earlier invocation with GDB_PERFTEST_MODE == compile.

	Tested on x86_64-linux.

	Implement DAP "hover" context
	A DAP client can request that an expression be evaluated in "hover"
	context, meaning that it should not cause side effects.  In gdb, this
	can be implemented by temporarily setting a few "may-" parameters to
	"off".

	In order to make this work, I had to also change "may-write-registers"
	so that it can be changed while the program is running.  I don't think
	there was any reason for this prohibition in the first place.

	Implement DAP logging breakpoints
	DAP allows a source breakpoint to specify a log message.  When this is
	done, the breakpoint acts more like gdb's dprintf: it logs a message
	but does not cause a stop.

	I looked into implement this using dprintf with the new %V printf
	format.  However, my initial attempt at this did not work, because
	when the inferior is continued, the dprintf output is captured by the
	gdb.execute call.  Maybe this could be fixed by having all
	inferior-continuation commands use the "&" form; the main benefit of
	this would be that expressions are only parsed a single time.

	Handle supportsVariablePaging in DAP
	A bug report about the supportsVariablePaging capability in DAP
	resulted in a clarification: when this capability is not present, DAP
	implementations should ignore the paging parameters to the "variables"
	request.  This patch implements this clarification.

	Implement type checking for DAP breakpoint requests
	I realized that with a small refactoring, it is possible to type-check
	the parameters to the various DAP breakpoint requests.  This would
	have caught the earlier bug involving hitCondition.

	Handle exceptions when creating DAP breakpoints
	When creating a DAP breakpoint, a failure should be returned by
	setting "verified" to False.  gdb didn't properly implement this, and
	there was a FIXME comment to this effect.  This patch fixes the
	problem.

	Reuse breakpoints more frequently in DAP
	The DAP breakpoint code tries to reuse a breakpoint when possible.
	Currently it uses the condition and the hit condition (aka ignore
	count) when making this determination.  However, these attributes are
	just going to be reset anyway, so this patch changes the code to
	exclude these from the reuse decision.

	Fix type of DAP hitCondition
	DAP specifies a breakpoint's hitCondition as a string, meaning it is
	an expression to be evaluated.  However, gdb implemented this as if it
	were an integer instead.  This patch fixes this oversight.

	gdb/DAP Few bug fixes & Evaluate Array Watch vars
	v2.

	EvaluateResult does not need a name, just as what Tom pointed out in
	previous review. It's only the *children* that need to be made sure that
	their names are valid. An identifier for a variable, can't ever have an
	integer as a name, anyhow (not as far as I am aware, no programming
	languages allow for that).

	Removed the f-strings and use str() instead as pointed out that
	f-strings might not be supported fully.

	v1.

	This patch fixes a few bugs.

	First of all, name of VariableReferences must always be of string type.
	This patch makes sure that this is the case by formatting the name. If
	(when) the name is an integer, this will cause clients to fail or throw
	errors.

	Fixes a bug in NoOpArrayPrinter that calculated children to be N, but
	only ever retrieves N-1 children, which makes Python at some time later
	(during fetch_children -> fetch_one_child(N) ) raise an exception (out
	of list index) which makes the entire request go bad.

	The result[self.result_name] also f-strings the printer.to_string()
	value, because this can potentially be a LazyString (which is a Python
	object, not a string) and is not serializable by json.dumps.

	    # initial terminal commands, where there's no prompt yet.
	...

	Indeed, before the "tui enable" command, the tuiterm is empty, so there is no
	prompt and just before switching to TUI we have in the tuiterm:
	...
	tui enable
	...

	The reason that there is no prompt, is that:
	- in order for tuiterm to show something, its input processing procs need to
	  be called, and
	- the initial gdb prompt, and subsequent prompts generated by gdb_test-style
	  procs, are all consumed by those procs instead.

	This is in principle not a problem, but the absence of a prompt makes a
	tuiterm session look less like a session on an actual xterm.

	Add a new proc gen_prompt, that:
	- generates a prompt using echo
	- consumes the response before the prompt using gdb_expect
	- consumes the prompt using Term::wait_for "".

	This allows us to reimplement Term::command_no_prompt_prefix using
	Term::command, and just before switching to TUI we have in the tuiterm:
	...
	(gdb) tui enable
	...

	Tested on x86_64-linux.

	[gdb/testsuite] Make Term::wait_for "" match only a prompt
	The semantics of Term::wait_for is:
	...
	    # Accept some output from gdb and update the screen.  WAIT_FOR is
	    # a regexp matching the line to wait for.  Return 0 on timeout, 1
	    # on success.
	    proc wait_for {wait_for} {
	...

	Note that besides the regexp, also a subsequent gdb prompt is matched.

	I recently used wait_for "" in a few test-cases, thinking that this would
	match just a prompt, but in fact that's not the case.

	Fix this in wait_for, and add a corresponding test in gdb.tui/tuiterm-2.exp.

	Tested on x86_64-linux.

	gdb/Python: Added ThreadExitedEvent
	v6:
	Fix comments.
	Fix copyright
	Remove unnecessary test suite stuff. save_var had to stay, as it mutates
	some test suite state that otherwise fails.

	v5:
	Did what Tom Tromey requested in v4; which can be found here: https://pi.simark.ca/gdb-patches/87pmjm0xar.fsf@tromey.com/

	v4:
	Doc formatting fixed.

	v3:
	Eli:
	Updated docs & NEWS to reflect new changes. Added
	a reference from the .ptid attribute of the ThreadExitedEvent
	to the ptid attribute of InferiorThread. To do this,
	I've added an anchor to that attribute.

	Tom:
	Tom requested that I should probably just emit the thread object;
	I ran into two issues for this, which I could not resolve in this patch;

	1 - The Thread Object (the python type) checks it's own validity
	by doing a comparison of it's `thread_info* thread` to nullptr. This
	means that any access of it's attributes may (probably, since we are
	in "async" land) throw Python exceptions because the thread has been
	removed from the thread object. Therefore I've decided in v3 of this
	patch to just emit most of the same fields that gdb.InferiorThread has, namely
	global_num, name, num and ptid (the 3-attribute tuple provided by
	gdb.InferiorThread.ptid).

	2 - A python user can hold a global reference to an exiting thread. Thus
	in order to have a ThreadExit event that can provide attribute access
	reliably (both as a global reference, but also inside the thread exit
	handler, as we can never guarantee that it's executed _before_ the
	thread_info pointer is removed from the gdbpy thread object),
	the `thread_info *` thread pointer must not be null. However, this
	comes at the cost of gdb.InferiorThread believing it is "valid" - which means,
	that if a user holds takes a global reference to that
	exiting event thread object, they can some time later do `t.switch()` at which
	point GDB will 'explode' so to speak.

	v2:
	Fixed white space issues and NULL/nullptr stuff,
	as requested by Tom Tromey.

	v1:
	Currently no event is emitted for a thread exit.

	This adds this functionality by emitting a new gdb.ThreadExitedEvent.

	It currently provides four attributes:
	- global_num: The GDB assigned global thread number
	- num: the per-inferior thread number
	- name: name of the thread or none if not set
	- ptid: the PTID of the thread, a 3-attribute tuple, identical to
	InferiorThread.ptid attribute

	Added info to docs & the NEWS file as well.

	Added test to test suite.

	Fixed formatting.

	Feedback wanted and appreciated.

	gdb/dap - Getting thread names
	Renamed thread_name according to convention (_ first)

	When testing firefox tests, it is apparent that
	_get_threads returns threads with name field = None.

	I had initially thought that this was due to Firefox setting the names
	using /proc/pid/task/tid/comm, by writing directly to the proc fs the
	names, but apparently GDB seems to catch this, because I re-wrote
	the basic-dap.exp/c to do this specifically and it saw the changes.

	So I couldn't determine right now, what operation of name change that
	GDB does not pick up, but with this patch, GDB will pick up the thread
	names for an applications that set the name of a thread in ways that

	Re: Add some expected failures for bfin linker tests
	After commit 7ade0f1582c4 I was seeing bfin-elf +XPASS: weak symbols,
	and on looking into the bfin targets a little, discovered we have two
	bfin-linux targets.  One, bfin-uclinux, is like bfin-elf in that
	ld -m elf32bfin is the default, and the other, bfin-linux-uclibc where
	ld -m elf32bfinfd is the default.  So putting bfin-*-*linux* in test
	xfails or elsewhere is wrong.  We want bfin-*-linux* instead to just
	select the fdpic bfin target.

	This patch corrects wrong bfin target triples in the ld testsuite,
	not just the recent change but others I'd added to xfails too.
	It also fixes the bfin-linux-uclibc ld-elf/64ksec fail

	In test-case gdb.base/step-over-exit.exp, we set a breakpoint on _exit and

	Without glibc debug info installed, we have with target board unix/-m64:
	...
	Thread 2.1 "step-over-exit" hit Breakpoint 2.2, 0x00007ffff7d46aee in \
	  _exit () from /lib64/libc.so.6^M

	  /lib/libc.so.6^M
	(gdb) PASS: gdb.base/step-over-exit.exp: continue to exit
	...

	However after installing debug info (packages glibc-debuginfo and
	glibc-32bit-debuginfo), we have for -m64 (note: __GI__exit instead of _exit):
	...
	Thread 2.1 "step-over-exit" hit Breakpoint 2.2, \

	asprintf memory leaks
	A number of backends want to return bfd_reloc_dangerous messaqes from

	[gdb/testsuite] Fix and add prompt anchoring in tuiterm
	There is a test-case that contains a unit test for tuiterm:
	gdb.tui/tuiterm.exp.

	However, this only excercises the tuiterm itself, and not the functions that
	interact with it, like Term::command.

	Add a new test-case gdb.tui/tuiterm-2.exp that:
	- overrides proc accept_gdb_output (to be able simulate incorrect responses
	  while avoiding the timeout),
	- overrides proc send_gdb (to be able to call Term::command without a gdb
	  instance, such that all tuiterm input is generated by the test-case).
	- issues Term::command calls, and
	- checks whether they behave correctly.

	This exposes a problem in Term::command.  The "prompt before command" regexp
	starts with a bit that is supposed to anchor the prompt to the border:
	...
		set str "(^|\|)$gdb_prompt $str"
	...
	but that doesn't work due to insufficient escaping.  Fix this by adding the
	missing escape:
	...
		set str "(^|\\|)$gdb_prompt $str"
	...

	Futhermore, the "prompt after command" regexp in Term::wait_for has no
	anchoring at all:
	...
		set prompt_wait_for "$gdb_prompt \$"
	...
	so add that as well.

	gdb/testsuite: use proper int size for gdb.dwarf2/symbol_needs_eval*.exp
	We recently realized that symbol_needs_eval_fail.exp and
	symbol_needs_eval_timeout.exp invalidly dereference an int (4 bytes on
	x86_64) by reading 8 bytes (the size of a pointer).

	Here how it goes:

	In gdb/testsuite/gdb.dwarf2/symbol_needs_eval.c a global variable is
	defined:

	    int exec_mask = 1;

	and later both tests build some DWARF using the assembler doing:

	    set exec_mask_var [gdb_target_symbol exec_mask]
	    ...
	        DW_TAG_variable {
	          {DW_AT_name a}
	          {DW_AT_type :$int_type_label}
	          {DW_AT_location {
	            DW_OP_addr $exec_mask_var
	            DW_OP_deref
	            ...
	          }
	        }

	The definition of the DW_OP_deref (from Dwarf5 2.5.1.3 Stack Operations)
	says that "The size of the data retrieved from the dereferenced address
	is the size of an address on the target machine."

	On x86_64, the size of an int is 4 while the size of an address is 8.
	The result is that when evaluating this expression, the debugger reads
	outside of the `a` variable.

	Fix this by using `DW_OP_deref_size $int_size` instead.  To achieve
	this, this patch adds the necessary steps so we can figure out what
	`sizeof(int)` evaluates to for the current target.

	While at it, also change the definition of the int type in the assembled
	DWARF information so we use the actual target's size for an int instead
	of the literal 4.

	Tested on x86_64 Linux.

	gdb/testsuite: Testing with the armflang compiler
	Currently the Fortran test suite does not run with armflang because the
	compiler detection fails. This in turn means fortran_runto_main does not
	know which main method to use to start a test case.

	Fortran compiler detection was added in 44d469c5f85; however, the commit
	message notes that it was not tested with armflang.

	This commit tests and fixes up a minor issue to get the detection
	working.

	The goal here is to get the tests running and preventing further
	regressions during future work. This change does not do anything to fix
	existing failures.

	>From what I can understand, the auto detection leverages the
	preprocessor to extract the Fortran compiler identity from the defines.
	This preprocessor output is then evaluated by the test suite to import
	these defines.

	In the case of armflang, this evaluation step is disrupted by the
	presence of the following warning:

	    $ armflang -E -fdiagnostics-color=never testsuite/lib/compiler.F90 -o compiler.exp
	    $ clang-13: warning: argument unused during compilation: '-fdiagnostics-color=never' [-Wunused-command-line-argument]

	The evaluation logic is already set up to filter this warning, but the
	prefix differs.

	This commit fixes the issue by updating the filter to exclude the
	armflang flavour of warning.

	gdb.fortran regression tests run with GNU, Intel and Intel LLVM. No
	regressions detected.

	The gdb.fortran test results with ACfL 23.04.1 are as follows.

	Before:

	 # of expected passes		560
	 # of unexpected failures	113
	 # of unresolved testcases	2
	 # of untested testcases	5
	 # of duplicate test names	2

	After:

	 # of expected passes		5388
	 # of unexpected failures	628
	 # of known failures		10
	 # of untested testcases	8
	 # of unsupported tests		5
	 # of duplicate test names	5

	As can be seen from the above, there are now considerably more passing
	assertions.

	Do not report totalFrames from DAP stackTrace request
	Currently, gdb will unwind the entire stack in response to the

	    If omitted or if `totalFrames` is larger than the available

	Add type-checking to DAP requests
	It occurred to me recently that gdb's DAP implementation should
	probably check the types of objects coming from the client.  This
	patch implements this idea by reusing Python's existing type
	annotations, and supplying a decorator that verifies these at runtime.

	Python doesn't make it very easy to do runtime type-checking, so the
	core of the checker is written by hand.  I haven't tried to make a
	fully generic runtime type checker.  Instead, this only checks the
	subset that is needed by DAP.  For example, only keyword-only
	functions are handled.

	Furthermore, in a few spots, it wasn't convenient to spell out the
	type that is accepted.  I've added a couple of comments to this effect
	in breakpoint.py.

	I've tried to make this code compatible with older versions of Python,
	but I've only been able to try it with 3.9 and 3.10.

	Use tuples for default arguments in DAP
	My co-worker Kévin taught me that using a mutable object as a default

	created a single time (when the function is defined), and so if it is
	mutated in the body of the function, the changes will stick around.

	This patch changes the cases like this in DAP to use () rather than []
	as the default.  This patch is merely preventative, as no bugs like
	this are in the code.

	With a gdb 13.2 based package on SLE-15 aarch64,  I run into:
	...
	(gdb) PASS: gdb.python/py-rbreak.exp: nosharedlibrary
	py sl = gdb.rbreak("^[^_]",minsyms=False)^M
	Breakpoint 2 at 0x4004ac: file ../sysdeps/aarch64/crti.S, line 63.^M
	  ...
	(gdb) py print(len(sl))^M
	12^M
	(gdb) FAIL: gdb.python/py-rbreak.exp: check number of returned breakpoints is 11
	...

	The FAIL is due to:
	- the glibc object crti.o containing debug information for function
	  call_weak_fn, and
	- the test-case not expecting this.

	The debug information is there due to compiling glibc using a binutils which
	contains commit 591cc9fbbfd ("gas/Dwarf: record functions").

	I've run into a similar issue before, see commit 3fbbcf473a5 ("[gdb/testsuite]
	Fix regexp in py-rbreak.exp").

	The fix I applied there was to use a regexp "^[^_]" to filter out
	__libc_csu_fini and __libc_csu_init, but that doesn't work for call_weak_fn.

	Fix this by:
	- reverting the regexp to "", and
	- rewriting the check to require at least 11 functions, rather than a precise
	  match.

	Tested on x86_64-linux.

	Permit DW_OP_GNU_uninit to be used with DW_OP_piece
	This commit implements a fix for a bug reported against GDB on
	Fedora bugzilla...

	https://bugzilla.redhat.com/show_bug.cgi?id=2166796

	The test case in that bug report involved running gdb against the 'jq'
	program (which is a command-line JSON processor) on Fedora 37.  Since
	the debug info is compiler (and compile-time option) dependent, it
	won't necessarily show up in other distributions or even past or
	future versions of Fedora.  (E.g. when trying the example shown below
	on Fedora 38, GDB says that the value of 'value' has been optimized
	out.  I.e. it does not demonstrate the same DWARF error that can be
	see when using Fedora 37.)

	That said, on Fedora 37, the bug could be reproduced as follows:

	[kev@f37-1 ~]$ gdb jq -q -ex 'b src/util.c:415' -ex 'r </dev/null'
	Reading symbols from jq...

	This GDB supports auto-downloading debuginfo from the following URLs:
	  <https://debuginfod.fedoraproject.org/>
	Enable debuginfod for this session? (y or [n]) y
	Debuginfod has been enabled.
	To make this setting permanent, add 'set debuginfod enabled on' to .gdbinit.
	Reading symbols from /home/kev/.cache/debuginfod_client/9d3c8b4197350a190a74972d481de32abf641aa4/debuginfo...

	Make breakpoint pending on future shared library load? (y or [n]) y
	Breakpoint 1 (src/util.c:415) pending.
	Starting program: /usr/bin/jq </dev/null
	[Thread debugging using libthread_db enabled]
	Using host libthread_db library "/lib64/libthread_db.so.1".

	Breakpoint 1, jq_util_input_next_input (state=0x55555555d7f0) at src/util.c:416
	416	    if (state->parser == NULL) {
	(gdb) p value
	DWARF-2 expression error: DW_OP_GNU_uninit must always be the very last op.

	This is undesirable - rather than output an error about the DWARF
	info, we'd prefer to see a value, even if it is uninitialized.

	Examination of the debuginfo showed the following:

	 <1><468f1>: Abbrev Number: 112 (DW_TAG_subprogram)
	    <468f2>   DW_AT_external    : 1
	    <468f2>   DW_AT_name        : (indirect string, offset: 0x4781): jq_util_input_next_input

	    <468f9>   DW_AT_prototyped  : 1

	    <468fd>   DW_AT_sibling     : <0x4692e>
	...
	 <2><46921>: Abbrev Number: 102 (DW_TAG_variable)
	    <46922>   DW_AT_name        : (indirect string, offset: 0x8cb): value
	    <46926>   DW_AT_decl_file   : 10
	    <46926>   DW_AT_decl_line   : 414
	    <46928>   DW_AT_decl_column : 6
	    <46929>   DW_AT_type        : <0x3f2>

	Note that there's no DW_AT_location, so I looked for an abstract origin entry:

	 <2><2dfa0>: Abbrev Number: 90 (DW_TAG_variable)
	    <2dfa1>   DW_AT_abstract_origin: <0x46921>
	    <2dfa5>   DW_AT_location    : 0x27cf1 (location list)
	    <2dfa9>   DW_AT_GNU_locviews: 0x27ce1

	(Note that the DW_AT_abstract_origin attribute's value is 0x46921 which
	is the DIE for the local variable "value".)

	Looking at the location list, I see:

	    00027cf1 v000000000000000 v000000000000000 views at 00027ce1 for:
	             000000000002f8fe 000000000002f92e (DW_OP_reg13 (r13); DW_OP_GNU_uninit; DW_OP_piece: 8; DW_OP_reg12 (r12); DW_OP_GNU_uninit; DW_OP_piece: 8)

	While DW_OP_GNU_uninit is not the very last op, it is the last op
	prior to DW_OP_piece.  The fix involved changing the DW_OP_GNU_uninit
	case in dwarf_expr_context::execute_stack_op in gdb/dwarf2/expr.c so
	that DW_OP_GNU_uninit may appear just before DW_OP_piece.

	With the fix in place, attempting to print 'value' now looks like
	this:

	(gdb) p value
	$1 =  [uninitialized] {kind_flags = 0 '\000', pad_ = 0 '\000', offset = 0,
	  size = 0, u = {ptr = 0x0, number = 0}}

	Note that "[uninitialized]" is part of the output.  (But also note
	that there's an extra space character.)

	I've made a new test case,
	gdb.dwarf2/DW_OP_piece_with_DW_OP_GNU_uninit.exp, by adapting an
	existing one, gdb.dwarf2/opt-out-not-implptr.exp.  Since it uses the
	DWARF assembler, the test case does not depend on a specific compiler
	version or compiler options.

	Tested on Fedora 37 and Fedora 38.

	libsframe: testsuite: add sframe_find_fre tests for pltN entries
	Add a new test plt-findfre-1 to ensure lookup of SFrame stack trace

	In this test, a dummy SFrame FDE of type SFRAME_FDE_TYPE_PCMASK is
	created.  The size of the 'function code block' covered by the SFrame
	FDE is equivalent to 5 pltN entries of 16 bytes each.

	The test first looks up SFrame FREs for some addresses in the first pltN
	entry, followed by lookups for some addresses in the fourth pltN entry.

	libsframe: fix sframe_find_fre for pltN entries
	To find SFrame stack trace information from an FDE of type
	SFRAME_FDE_TYPE_PCMASK, sframe_find_fre () was doing an operation
	like,
	  (start_ip_offset & 0xff) >= (pc & 0xff), etc.

	This is buggy and needs correction.  The mask 0xff should be 0xf (to
	work for a pltN entry of size say, 16 bytes).

	At this time, the size of the pltN entry is implicitly assumed to be 16
	bytes by libsframe.  In next version of the SFrame format, we can encode
	this information explicitly in the SFrame FDE.

	For now, we should fix the code to at least behave correctly for the
	generated code and the generated SFrame stack trace information for the
	pltN entries on x86_64.

	libsframe/
		* sframe.c (sframe_find_fre): Correct the bitmask used for
		SFrame FDEs of type SFRAME_FDE_TYPE_PCMASK.

	gdb/debuginfod: cleanup debuginfod earlier
	A GDB crash was discovered on Fedora GDB that was tracked back to an
	issue with the way that debuginfod is cleaned up.

	The bug was reported on Fedora 37, 38, and 39.  Here are the steps to
	reproduce:

	1. The file /etc/ssl/openssl.cnf contains the following lines:

	   [provider_sect]
	   default = default_sect
	   ##legacy = legacy_sect
	   ##
	   [default_sect]
	   activate = 1

	   ##[legacy_sect]
	   ##activate = 1

	   The bug will occur when the '##' characters are removed so that the
	   lines in question look like this:

	   [provider_sect]
	   default = default_sect
	   legacy = legacy_sect

	   [default_sect]
	   activate = 1

	   [legacy_sect]
	   activate = 1

	2. Clean up any existing debuginfod cache data:

	   > rm -rf $HOME/.cache/debuginfod_client

	3. Run GDB:

	   > gdb -nx -q -iex 'set trace-commands on' \
	                -iex 'set debuginfod enabled on' \
	                -iex 'set confirm off' \
			-ex 'start' -ex 'quit' /bin/ls
	   +set debuginfod enabled on
	   +set confirm off
	   Reading symbols from /bin/ls...
	   Downloading separate debug info for /usr/bin/ls
	   ... snip ...
	   Temporary breakpoint 1, main (argc=1, argv=0x7fffffffde38) at ../src/ls.c:1646
	   1646    {
	   +quit

	   Fatal signal: Segmentation fault
	   ----- Backtrace -----
	   ... snip ...

	So GDB ends up crashing during exit.

	What's happening is that when debuginfod is initialised
	debuginfod_begin is called (this is in the debuginfod library), this
	in turn sets up libcurl, which makes use of openssl.  Somewhere during
	this setup process an at_exit function is registered to cleanup some
	state.

	Back in GDB the debuginfod_client object is managed using this code:

	  /* Deleter for a debuginfod_client.  */

	  struct debuginfod_client_deleter
	  {
	    void operator() (debuginfod_client *c)
	    {
	      debuginfod_end (c);
	    }
	  };

	  using debuginfod_client_up
	    = std::unique_ptr<debuginfod_client, debuginfod_client_deleter>;

	And then a global debuginfod_client_up is created to hold a pointer to
	the debuginfod_client object.  As a global this will be cleaned up
	using the standard C++ global object destructor mechanism, which is
	run after the at_exit handlers.

	However, it is expected that when debuginfod_end is called the
	debuginfod_client object will still be in a usable state, that is, we
	don't expect the at_exit handlers to have run and started cleaning up
	the library state.

	To fix this issue we need to ensure that debuginfod_end is called
	before the at_exit handlers have a chance to run.

	This commit removes the debuginfod_client_up type, and instead has GDB
	hold a raw pointer to the debuginfod_client object.  We then make use
	of GDB's make_final_cleanup to register a function that will call
	debuginfod_end.

	As GDB's final cleanups are called before exit is called, this means
	that debuginfod_end will be called before the at_exit handlers are
	called, and the crash identified above is resolved.

	It's not obvious how this issue can easily be tested for. The bug does
	not appear to manifest when using a local debuginfod server, so we'd
	need to setup something more involved.  For now I'm proposing this
	patch without any associated tests.

	The problem is in cli/cli-cmds.c, in the function setting_cmd, where
	we do this:

	  const char *a0 = (const char *) argv[0]->contents ().data ();

	Here argv[0] is a value* which we know is either a TYPE_CODE_ARRAY or
	a TYPE_CODE_STRING.  The problem is that the above line is casting the
	value contents directly to a C-string, i.e. one that is assumed to
	have a null-terminator at the end.

	After the above commit this can no longer be assumed to be true.  A
	string value will be represented just as it would be in the current
	language, so for Ada and Fortran the string will be an array of
	characters with no null-terminator at the end.

	My proposed solution is to copy the string contents into a std::string
	object, and then use the std::string::c_str() value, this will ensure
	that a null-terminator has been added.

	I had a check through GDB at places TYPE_CODE_STRING was used and
	couldn't see any other obvious places where this type of assumption
	was being made, so hopefully this is the only offender.

	Running the above test with ASan compiled in no longer gives an error.

	ecoff find_nearest_line and final link leaks
	Freeing ecoff_debug_info "pointers to the unswapped symbolic info"
	isn't a simple matter, due to differing allocation strategies.  In

	gdb/corelow.c: do not try to reopen a file if open failed once
	In the current implementation, core_target::build_file_mappings will try
	to locate and open files which were mapped in the process for which the
	core dump was produced.  If the file cannot be found or cannot be
	opened, GDB will re-try to open it once for each time it was mapped in
	the process's address space.

	This patch makes it so GDB recognizes that it has already failed to open
	a given file once and does not re-try the process for each mapping.

	gdb/corelow.c: avoid repeated warnings in build_file_mappings
	When GDB opens a coredump it tries to locate and then open all files
	which were mapped in the process.

	If a file is found but cannot be opened with BFD (bfd_open /
	bfd_check_format fails), then a warning is printed to the user.  If the
	same file was mapped multiple times in the process's address space, the
	warning is printed once for each time the file was mapped.  I find this
	un-necessarily noisy.

	This patch makes it so the warning message is printed only once per
	file.

	There was a comment in the code assuming that if the file was found on
	the system, opening it (bfd_open + bfd_check_format) should always
	succeed.  A recent change in BFD (014a602b86f "Don't optimise bfd_seek
	to same position") showed that this assumption is not valid.  For
	example, it is possible to have a core dump of a process which had
	mmaped an IO page from a DRI render node (/dev/dri/runderD$NUM).  In
	such case the core dump does contain the information that portions of
	this special file were mapped in the host process, but trying to seek to
	position 0 will fail, making bfd_check_format fail.  This patch removes
	this comment.

	gdb/corelow.c: fix use-after-free in build_file_mappings
	In core_target::build_file_mappings, GDB tries to open files referenced
	in the core dump.

	The process goes like this:

	    struct bfd *bfd = bfd_map[filename];
	    if (bfd == nullptr)
	      {
	        bfd = bfd_map[filename]
	          = bfd_openr (expanded_fname.get (), "binary");
	        if (bfd == nullptr || !bfd_check_format (bfd, bfd_object))
	          {
	            if (bfd != nullptr)
	              bfd_close (bfd);
	            return;
	          }
	      }
	    asection *sec = bfd_make_section_anyway (bfd, "load");
	    ...

	The problem is that if bfd_check_format fails, we close the bfd but keep
	a reference to it in the bfd_map.

	If the same filename appears another time in the NT_FILE note, we enter
	this code again.  The second time, bfd_map[filename] is not nullptr and
	we try to call bfd_make_section_anyway on an already closed BFD, which
	is a use-after-free error.

	This patch makes sure that the bfd is only saved in the bfd_map if it
	got opened successfully.

	This error got exposed by a recent change in BFD (014a602b86f "Don't
	optimise bfd_seek to same position").  Since this change, opening a
	coredump which contains mapping to some special files such as a DRI
	render node (/dev/dri/renderD$NUM) exposes the issue.  This happens for
	example for processes using AMDGPU devices to offload compute tasks.

	[gdb/cli] Handle pending ^C after rl_callback_read_char for readline 7
	In commit faf01aee1d0 ("[gdb] Handle pending ^C after rl_callback_read_char")
	we handled a problem (described in detail in that commit) for readline >= 8
	using public readline functions rl_pending_signal and rl_check_signals.

	For readline 7 (note that we require at least readline 7 so there's no need to
	worry about readline 6), there was no fix though, because rl_check_signals was
	not available.

	Fix this by instead using the private readline function _rl_signal_handler.

	There is precedent for using private readline variables and functions, but
	it's something we want to get rid of (PR build/10723).  Nevertheless, I think
	we can allow this specific instance because it's not used when building
	against readline >= 8.

	[ In the meanwhile, a fix was committed in the devel branch of the readline
	repo, contained in commit 8d0c439 ("rollup of changes since readline-8.2"),
	first proposed here (
	https://lists.gnu.org/archive/html/bug-readline/2022-10/msg00008.html ). ]

	_bfd_free_cached_info
	doc/bfdint.texi and comments in the aout and som code about this
	function are just wrong, and its name is not very apt.  Better would
	be _bfd_mostly_destroy, and we certainly should not be saying anything
	about the possibility of later recreating anything lost by this
	function.  What's more, if _bfd_free_cached_info is called when
	creating an archive map to reduce memory usage by throwing away
	symbols, the target _close_and_cleanup function won't have access to
	tdata or section bfd_user_data to tidy memory.  This means most of the
	target _close_and_cleanup function won't do anything, and therefore
	sometimes will result in memory leaks.

	This patch fixes the documentation problems and moves most of the
	target _close_and_cleanup code to target _bfd_free_cached_info.
	Another notable change is that bfd_generic_bfd_free_cached_info is now
	defined as _bfd_free_cached_info rather than _bfd_bool_bfd_true,
	ie. the default now frees objalloc memory.

	gdb: building inferior strings from within GDB
	History Of This Patch
	=====================

	This commit aims to address PR gdb/21699.  There have now been a
	couple of attempts to fix this issue.  Simon originally posted two
	patches back in 2021:

	  https://sourceware.org/pipermail/gdb-patches/2021-July/180894.html
	  https://sourceware.org/pipermail/gdb-patches/2021-July/180896.html

	Before Pedro then posted a version of his own:

	  https://sourceware.org/pipermail/gdb-patches/2021-July/180970.html

	After this the conversation halted.  Then in 2023 I (Andrew) also took
	a look at this bug and posted two versions:

	  https://sourceware.org/pipermail/gdb-patches/2023-April/198570.html
	  https://sourceware.org/pipermail/gdb-patches/2023-April/198680.html

	The approach taken in my first patch was pretty similar to what Simon
	originally posted back in 2021.  My second attempt was only a slight
	variation on the first.

	Pedro then pointed out his older patch, and so we arrive at this
	patch.  The GDB changes here are mostly Pedro's work, but updated by
	me (Andrew), any mistakes are mine.

	The tests here are a combinations of everyone's work, and the commit
	message is new, but copies bits from everyone's earlier work.

	Problem Description
	===================

	Bug PR gdb/21699 makes the observation that using $_as_string with
	GDB's printf can cause GDB to print unexpected data from the
	inferior.  The reproducer is pretty simple:

	  #include <stddef.h>
	  static char arena[100];

	  /* Override malloc() so value_coerce_to_target() gets a known
	     pointer, and we know we"ll see an error if $_as_string() gives
	     a string that isn't null terminated. */
	  void
	  *malloc (size_t size)
	  {
	      memset (arena, 'x', sizeof (arena));
	      if (size > sizeof (arena))
	          return NULL;
	      return arena;
	  }

	  int
	  main ()
	  {
	    return 0;
	  }

	And then in a GDB session:

	  $ gdb -q test
	  Reading symbols from /tmp/test...
	  (gdb) start
	  Temporary breakpoint 1 at 0x4004c8: file test.c, line 17.
	  Starting program: /tmp/test

	  Temporary breakpoint 1, main () at test.c:17
	  17        return 0;
	  (gdb) printf "%s\n", $_as_string("hello")
	  "hello"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
	  (gdb) quit

	The problem above is caused by how value_cstring is used within
	py-value.c, but once we understand the issue then it turns out that
	value_cstring is used in an unexpected way in many places within GDB.

	Within py-value.c we have a null-terminated C-style string.  We then
	pass a pointer to this string, along with the length of this
	string (so not including the null-character) to value_cstring.

	In value_cstring GDB allocates an array value of the given character
	type, and copies in requested number of characters.  However
	value_cstring does not add a null-character of its own.  This means
	that the value created by calling value_cstring is only
	null-terminated if the null-character is included in the passed in
	length.  In py-value.c this is not the case, and indeed, in most uses
	of value_cstring, this is not the case.

	When GDB tries to print one of these strings the value contents are
	pushed to the inferior, and then read back as a C-style string, that
	is, GDB reads inferior memory until it finds a null-terminator.  For
	the py-value.c case, no null-terminator is pushed into the inferior,
	so GDB will continue reading inferior memory until a null-terminator
	is found, with unpredictable results.

	Patch Description
	=================

	The first thing this patch does is better define what the arguments
	for the two function value_cstring and value_string should represent.
	The comments in the header file are updated to describe whether the
	length argument should, or should not, include a null-character.
	Also, the data argument is changed to type gdb_byte.  The functions as
	they currently exist will handle wide-characters, in which case more
	than one 'char' would be needed for each character.  As such using
	gdb_byte seems to make more sense.

	To avoid adding casts throughout GDB, I've also added an overload that
	still takes a 'char *', but asserts that the character type being used
	is of size '1'.

	The value_cstring function is now responsible for adding a null
	character at the end of the string value it creates.

	However, once we start looking at how value_cstring is used, we
	realise there's another, related, problem.  Not every language's
	strings are null terminated.  Fortran and Ada strings, for example,
	are just an array of characters, GDB already has the function
	value_string which can be used to create such values.

	Consider this example using current GDB:

	  (gdb) set language ada
	  (gdb) p $_gdb_setting("arch")
	  $1 = (97, 117, 116, 111)
	  (gdb) ptype $
	  type = array (1 .. 4) of char
	  (gdb) p $_gdb_maint_setting("test-settings string")
	  $2 = (0)
	  (gdb) ptype $
	  type = array (1 .. 1) of char

	This shows two problems, first, the $_gdb_setting and
	$_gdb_maint_setting functions are calling value_cstring using the
	builtin_char character, rather than a language appropriate type.  In
	the first call, the 'arch' case, the value_cstring call doesn't
	include the null character, so the returned array only contains the
	expected characters.  But, in the $_gdb_maint_setting example we do
	end up including the null-character, even though this is not expected
	for Ada strings.

	This commit adds a new language method language_defn::value_string,
	this function takes a pointer and length and creates a language
	appropriate value that represents the string.  For C, C++, etc this
	will be a null-terminated string (by calling value_cstring), and for
	Fortran and Ada this can be a bounded array of characters with no null
	terminator.  Additionally, this new language_defn::value_string
	function is responsible for selecting a language appropriate character
	type.

	After this commit the only calls to value_cstring are from the C
	expression evaluator and from the default language_defn::value_string.

	And the only calls to value_string are from Fortan, Ada, and ObjectC
	related code.

	MIPS: sync oprand char usage between mips and micromips

	  ^  is added for 5bit sa oprand for some new DSPr2 instructions:
		APPEND, PREPEND, PRECR_SRA[_R].PH.W
		the LSB bit is 11, like RD.
	  +t is removed for coprocessor 0 destination register.
		'E' does the samething.
	  +t is now used for RX oprand for MFTR/MTTR (MT ASE)
	  ?  is added for sel oprand for MFTR/MTTR (MT ASE)
		For mips32, the position of sel in MFTR/MTTR is same with mfc0 etc,
		while for micromips, they are different.

	We also add an extesion format of cftc2/cttc2/mftc2/mfthc2/mttc2/mtthc2:
		concatenating rs with rx as the index of control or data.

		run_dump_test_n32l
		run_dump_test_n64l
	Which use `-march=from-abi` for pre-R6 testcases,
	like micromips/mips16e etc.

	For cases doesn't use run_dump_test_*, we use
		-mips32r2 for micromips32
		-mips1 for mips16-32
		-march=from-abi for testcases to o32/n32/n64 both/all.

	Replace `addi` with `addiu` for some cases for both r6 and pre-R6.

	Introduce some new testcases for r6 with FPXX/FP64.
	Introduce new testcase: comdat-reloc-r6.

	Skip `default` in mips_arch_list_matching if triple is mipsisa*, due to:
	  1)it will cannot match mipsr6@*.d: since mips32rN/mips64rN
	    will always be used, it won't be a problem.
	  2)some test think -march=mips64rN will alway true for mipsisa64rN,
	    which is not true now.

	This patch fix testsuite for all r6-default gnu triples:

	Harden PowerPC64 OPD handling against fuzzers
	PowerPC64 ELFv1 object files should have at most one .opd section, and
	OPD handling in elf64-ppc.c makes use of this fact by caching some
	.opd section info in the per-object bfd.tdata.  This was done to avoid
	another word in the target specific section data.  Of course, fuzzers
	don't respect the ABI, and even non-malicious users can accidentally
	create multiple .opd sections.  So it is better to avoid possible
	buffer overflows and other confusion when OPD handling for a second
	.opd section references data for the first .opd section, by keeping
	the data per-section.

	The patch also fixes a memory leak, and a corner case where I think we
	could hit an assertion in opd_entry_value or read out of bounds in
	ppc64_elf_branch_reloc doing a final link producing non-ppc64 output.
	(It's a really rare corner case because not only would you need to be
	linking ppc64 objects to non-ppc64 output, you'd also need a branch
	reloc symbol to be defined in a .opd section of a non-ppc64 input.)

	[gdb/tui] Fix fingerprint for cmd-only layout
	I added a cmd-only layout:
	...
	(gdb) tui new-layout cmd cmd 1
	...
	and set it:
	...
	(gdb) layout cmd
	...
	which gave me the expect result: only the cmd window in the screen.

	However, after going back to layout src:
	...
	(gdb) layout src
	...
	I got a source window with only one line in it, and the cmd window taking most
	of the screen.

	I traced this back to tui_set_layout, where for both the old and the new
	layout the fingerprint of the cmd window in the layout is taken.  If the
	fingerprint is the same, an effort will be done to preserve the command
	window size.

	The fingerprint is "VC" for both the old (cmd) and new (src) layouts, which
	explains the behaviour.

	I think this is essentially a bug in the finger print calculation, and it
	should be "C" for the cmd layout.

	Fix this by not adding a V or H in the fingerprint if the list size is one.

	Tested on x86_64-linux.

	gdb: add support for %V to printf command
	This commit adds a new format for the printf and dprintf commands:
	'%V'.  This new format takes any GDB expression and formats it as a
	string, just as GDB would for a 'print' command, e.g.:

	  (gdb) print a1
	  $a = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
	  (gdb) printf "%V\n", a1
	  {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
	  (gdb)

	It is also possible to pass the same options to %V as you might pass
	to the print command, e.g.:

	  (gdb) print -elements 3 -- a1
	  $4 = {2, 4, 6...}
	  (gdb) printf "%V[-elements 3]\n", a1
	  {2, 4, 6...}
	  (gdb)

	This new feature would effectively replace an existing feature of GDB,
	the $_as_string builtin convenience function.  However, the
	$_as_string function has a few problems which this new feature solves:

	1. $_as_string doesn't currently work when the inferior is not
	running, e.g:

	  (gdb) printf "%s", $_as_string(a1)
	  You can't do that without a process to debug.
	  (gdb)

	The reason for this is that $_as_string returns a value object with
	string type.  When we try to print this we call value_as_address,
	which ends up trying to push the string into the inferior's address
	space.

	Clearly we could solve this problem, the string data exists in GDB, so
	there's no reason why we have to push it into the inferior, but this
	is an existing problem that would need solving.

	2. $_as_string suffers from the fact that C degrades arrays to
	pointers, e.g.:

	  (gdb) printf "%s\n", $_as_string(a1)
	  0x404260 <a1>
	  (gdb)

	The implementation of $_as_string is passed a gdb.Value object that is
	a pointer, it doesn't understand that it's actually an array.  Solving
	this would be harder than issue #1 I think.  The whole array to
	pointer transformation is part of our expression evaluation.  And in
	most cases this is exactly what we want.  It's not clear to me how
	we'd (easily) tell GDB that we didn't want this reduction in _some_
	cases.  But I'm sure this is solvable if we really wanted to.

	3. $_as_string is a gdb.Function sub-class, and as such is passed
	gdb.Value objects.  There's no super convenient way to pass formatting
	options to $_as_string.  By this I mean that the new %V feature
	supports print formatting options.  Ideally, we might want to add this
	feature to $_as_string, we might imagine it working something like:

	  (gdb) printf "%s\n", $_as_string(a1,
	                                   elements = 3,
	                                   array_indexes = True)

	where the first item is the value to print, while the remaining
	options are the print formatting options.  However, this relies on
	Python calling syntax, which isn't something that convenience
	functions handle.  We could possibly rely on strictly positional
	arguments, like:

	  (gdb) printf "%s\n", $_as_string(a1, 3, 1)

	But that's clearly terrible as there's far more print formatting
	options, and if you needed to set the 9th option you'd need to fill in
	all the previous options.

	And right now, the only way to pass these options to a gdb.Function is
	to have GDB first convert them all into gdb.Value objects, which is
	really overkill for what we want.

	The new %V format solves all these problems: the string is computed
	and printed entirely on the GDB side, we are able to print arrays as
	actual arrays rather than pointers, and we can pass named format
	arguments.

	Finally, the $_as_string is sold in the manual as allowing users to
	print the string representation of flag enums, so given:

	  enum flags
	    {
	      FLAG_A = (1 << 0),
	      FLAG_B = (1 << 1),
	      FLAG_C = (1 << 1)
	    };

	  enum flags ff = FLAG_B;

	We can:

	  (gdb) printf "%s\n", $_as_string(ff)
	  FLAG_B

	This works just fine with %V too:

	  (gdb) printf "%V\n", ff
	  FLAG_B

	So all functionality of $_as_string is replaced by %V.  I'm not
	proposing to remove $_as_string, there might be users currently
	depending on it, but I am proposing that we don't push $_as_string in
	the documentation.

	As %V is a feature of printf, GDB's dprintf breakpoints naturally gain
	access to this feature too.  dprintf breakpoints can be operated in
	three different styles 'gdb' (use GDB's printf), 'call' (call a
	function in the inferior), or 'agent' (perform the dprintf on the
	remote).

	The use of '%V' will work just fine when dprintf-style is 'gdb'.

	When dprintf-style is 'call' the format string and arguments are
	passed to an inferior function (printf by default).  In this case GDB
	doesn't prevent use of '%V', but the documentation makes it clear that
	support for '%V' will depend on the inferior function being called.

	I chose this approach because the current implementation doesn't place
	any restrictions on the format string when operating in 'call' style.
	That is, the user might already be calling a function that supports
	custom print format specifiers (maybe including '%V') so, I claim, it
	would be wrong to block use of '%V' in this case.  The documentation
	does make it clear that users shouldn't expect this to "just work"
	though.

	When dprintf-style is 'agent' then GDB does no support the use of
	'%V' (right now).  This is handled at the point when GDB tries to
	process the format string and send the dprintf command to the remote,
	here's an example:

	  Reading symbols from /tmp/hello.x...
	  (gdb) dprintf call_me, "%V", a1
	  Dprintf 1 at 0x401152: file /tmp/hello.c, line 8.
	  (gdb) set sysroot /
	  (gdb) target remote | gdbserver --once - /tmp/hello.x
	  Remote debugging using | gdbserver --once - /tmp/hello.x
	  stdin/stdout redirected
	  Process /tmp/hello.x created; pid = 3088822
	  Remote debugging using stdio
	  Reading symbols from /lib64/ld-linux-x86-64.so.2...
	  (No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
	  0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
	  (gdb) set dprintf-style agent
	  (gdb) c
	  Continuing.
	  Unrecognized format specifier 'V' in printf
	  Command aborted.
	  (gdb)

	This is exactly how GDB would handle any other invalid format
	specifier, for example:

	  Reading symbols from /tmp/hello.x...
	  (gdb) dprintf call_me, "%Q", a1
	  Dprintf 1 at 0x401152: file /tmp/hello.c, line 8.
	  (gdb) set sysroot /
	  (gdb) target remote | gdbserver --once - /tmp/hello.x
	  Remote debugging using | gdbserver --once - /tmp/hello.x
	  stdin/stdout redirected
	  Process /tmp/hello.x created; pid = 3089193
	  Remote debugging using stdio
	  Reading symbols from /lib64/ld-linux-x86-64.so.2...
	  (No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
	  0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
	  (gdb) set dprintf-style agent
	  (gdb) c
	  Continuing.
	  Unrecognized format specifier 'Q' in printf
	  Command aborted.
	  (gdb)

	The error message isn't the greatest, but improving that can be put
	off for another day I hope.

	gdb: add interp::on_signal_received method
	Instead of having the interpreter code registering observers for the
	signal_received observable, add a "signal_received" virtual method to
	struct interp.  Add a interps_notify_signal_received function that loops
	over all UIs and calls the signal_received method on the interpreter.
	Finally, add a notify_signal_received function that calls
	interps_notify_signal_received and then notifies the observers.  Replace
	all existing notifications to the signal_received observers with calls
	to notify_signal_received.

	Before this patch, the CLI and MI code both register a signal_received
	observer.  These observer go over all UIs, and, for those that have a
	interpreter of the right kind, print the stop notifiation.

	After this patch, we have just one "loop over all UIs", inside
	interps_notify_signal_received.  Since the interp::on_signal_received
	method gets called once for each interpreter, the implementations only
	need to deal with the current interpreter (the "this" pointer).

	The motivation for this patch comes from a future patch, that makes the
	amdgpu code register an observer to print a warning after the CLI's
	signal stop message.  Since the amdgpu and the CLI code both use
	observers, the order of the two messages is not stable, unless we define
	the priority using the observer dependency system.  However, the
	approach of using virtual methods on the interpreters seems like a good
	change anyway, I think it's more straightforward and simple to
	understand than the current solution that uses observers.  We are sure
	that the amdgpu message gets printed after the CLI message, since
	observers are notified after interpreters.

	Keep the signal_received, even if nothing uses if, because we will be
	using it in the upcoming amdgpu patch implementing the warning described
	above.

	[gdb] Mention --with/without-system-readline for --configuration
	Simon reported that the new test-case gdb.tui/pr30056.exp fails with system
	readline.

	This is because the test-case requires a fix in readline that's present in our
	in-repo copy of readline, but most likely not in any system readline yet.

	Fix this by:
	- mentioning --with-system-readline or --without-system-readline in the
	  configuration string.
	- adding a new proc with_system_readline that makes this information available
	  in the testsuite.
	- using this in test-case gdb.tui/pr30056.exp to declare it unsupported for
	  --with-system-readline.

	Tested on x86_64-linux.

	arm-pe objdump -P
	arm-pe looks to be a very old PE implementation, incompatible with
	current arm-wince-pe.  arm-pe has different relocations and uses
	ARMMAGIC which has this comment: "I just made this up".  Well, OK, I
	don't know the history but it was probably before Microsoft "just made
	up" their constants for ARM windows CE.

	This patch supports objdump -P for arm-pe, and another magic constant
	that may appear in object files.  (I don't think binutils generates
	files using ARMV7PEMAGIC aka IMAGE_FILE_MACHINE_ARMNT.)

	[gdb/testsuite] Fix linefeed scrolling in tuiterm
	I came across a bug in the implementation of line feed in tuiterm, and added a
	unit test that exposes it.

	Before sending the line feed we have:
	...
	Screen Dump (size 8 columns x 4 rows, cursor at column 0, row 3):
	    0 abcdefgh
	    1 ijklmnop
	    2 qrstuvwx
	    3 yz01234
	...
	and after it we have:
	...
	Screen Dump (size 8 columns x 4 rows, cursor at column 0, row 1):
	    0 ijklmnop
	    1 qrstuvwx
	    2 yz01234
	    3 yz01234
	...

	Note how the cursor started at row 3 and after the line feed ended up at
	row 1, while it should have stayed in row 3.

	Fix this by moving "incr _cur_row -1" one level up in the loop nest in
	proc _ctl_0x0a.

	Tested on x86_64-linux.

	gdb/mi: fix ^running record with multiple MI interpreters
	I stumbled on the mi_proceeded and running_result_record_printed
	globals, which are shared by all MI interpreter instances (it's unlikely
	that people use multiple MI interpreter instances, but it's possible).
	After poking at it, I found this bug:

	1. Start GDB in MI mode
	2. Add a second MI interpreter with the new-ui command
	3. Use -exec-run on the second interpreter

	This is the output I get on the first interpreter:

	    =thread-group-added,id="i1"
	    ~"Reading symbols from a.out...\n"
	    ~"New UI allocated\n"
	    (gdb)
	    =thread-group-started,id="i1",pid="94718"
	    =thread-created,id="1",group-id="i1"
	    ^running
	    *running,thread-id="all"

	And this is the output I get on the second intepreter:

	    =thread-group-added,id="i1"
	    (gdb)
	    -exec-run
	    =thread-group-started,id="i1",pid="94718"
	    =thread-created,id="1",group-id="i1"
	    *running,thread-id="all"

	The problem here is that the `^running` reply to the -exec-run command
	is printed on the wrong UI.  It is printed on the first one, it should
	be printed on the second (the one on which we sent the -exec-run).

	What happens under the hood is that captured_mi_execute_command, while
	executing a command for the second intepreter, clears the
	running_result_record_printed and mi_proceeded globals.
	mi_about_to_proceed then sets mi_proceeded.  Then, mi_on_resume_1 gets
	called for the first intepreter first.  Since the

	    !running_result_record_printed && mi_proceeded

	condition is true, it prints a ^running, and sets
	running_result_record_printed.  When mi_on_resume_1 gets called for the
	second interpreter, running_result_record_printed is already set, so
	^running is not printed there.

	It took me a while to understand the relationship between these two
	variables.  I think that in the end, this is what we want to track:

	 1. When executing an MI command, take note if that command causes a
	    "proceed".  This is done in mi_about_to_proceed.
	 2. In mi_on_resume_1, if the command indeed caused a "proceed", we want
	    to output a ^running record.  And we want to remember that we did,
	    because...
	 3. Back in captured_mi_execute_command, if we did not output a
	    ^running, we want to output a ^done.

	Moving those two variables to the mi_interp struture appears to fix it.
	Only for the interpreter doing the -exec-run command does the
	running_result_record_printed flag get cleared, and therefore only or
	that one does the ^running record get printed.

	Add a new test for this, that does pretty much what the reproducer above
	shows.  Without the fix, the test fails because
	mi_send_resuming_command_raw never sees the ^running record.

	[readline] Fix double free in _rl_scxt_dispose
	Consider the following scenario.  We start gdb in TUI mode:
	...
	$ gdb -q -tui
	...
	and type ^R which gives us the reverse-isearch prompt in the cmd window:
	...
	(reverse-i-search)`':
	...
	and then type "foo", right-arrow-key, and ^C.

	In TUI mode, gdb uses a custom rl_getc_function tui_getc.

	When pressing the right-arrow-key, tui_getc:
	- attempts to scroll the TUI src window, without any effect, and
	- returns 0.

	The intention of returning 0 is mentioned here in tui_dispatch_ctrl_char:
	...
	  /* We intercepted the control character, so return 0 (which readline
	     will interpret as a no-op).  */
	  return 0;
	...

	However, after this 0 is returned by the rl_read_key () call in
	_rl_search_getchar, _rl_read_mbstring is called, which incorrectly interprets
	0 as the first part of an utf-8 multibyte char, and tries to read the next
	char.

	In this state, the ^C takes effect and we run into a double free because
	_rl_isearch_cleanup is called twice.

	Both these issues need fixing independently, though after fixing the first we
	no longer trigger the second.

	The first issue is caused by the subtle difference between:
	- a char array containing 0 chars, which is zero-terminated, and
	- a char array containing 1 char, which is zero.

	In mbrtowc terms, this is the difference between:
	...
	  mbrtowc (&wc, "", 0, &ps);
	...
	which returns -2, and:
	...
	  mbrtowc (&wc, "", 1, &ps);
	...
	which returns 0.

	Note that _rl_read_mbstring calls _rl_get_char_len without passing it an
	explicit length parameter, and consequently it cannot distinguish between the
	two, and defaults to the "0 chars" choice.

	Note that the same problem doesn't exist in _rl_read_mbchar.

	Fix this by defaulting to the "1 char" choice in _rl_get_char_len:
	...
	-  if (_rl_utf8locale && l > 0 && UTF8_SINGLEBYTE(*src))
	+  if (_rl_utf8locale && l >= 0 && UTF8_SINGLEBYTE(*src))
	...

	The second problem happens when the call to _rl_search_getchar in
	_rl_isearch_callback returns.  At that point _rl_isearch_cleanup has already
	been called from the signal handler, but we proceed regardless, using a cxt
	pointer that has been freed.

	Fix this by checking for "RL_ISSTATE (RL_STATE_ISEARCH)" after the call to
	_rl_search_getchar:
	...
	   c = _rl_search_getchar (cxt);
	+  if (!RL_ISSTATE (RL_STATE_ISEARCH))
	+    return 1;
	...

	Tested on x86_64-linux.

	[PR ld/22263][PR ld/25694] RISC-V: Avoid dynamic TLS relocs in PIE.
	Lots of targets already fixed the TEXTREL problem for TLS in PIE.

	* For PR ld/25694,
	In the check_reloc, refer to spare and loongarch, they don't need to reserve
	any local dynamic reloc for TLS LE in pie/pde, and similar to other targets.
	So it seems like riscv was too conservative to estimate the TLS LE before.
	Just break and don't goto static_reloc for TLS LE in pie/pde can fix the
	TEXTREL problem.

	* For PR ld/22263,
	The risc-v code for TLS GD/IE in the relocate_section seems same as MIPS port.
	So similar to MIPS, pr22570, commits 9143e72c6d4d and 1cb83cac9a89, it seems
	also the right way to do the same thing for risc-v.

	On risc-v, fixes

	iamcu: suppress tests which can't possibly work
	With neither --32 nor --64 passed to gas, advanced features like AVX
	aren't available without explicitly enabling them.

	x86-64: improve gas diagnostic when no 32-bit target is configured
	Make this similar to --64 and --x32: Check whether a suitable target
	exists.

	x86-64: conditionalize tests using --32
	Using this option doesn't really work when no support for any 32-bit
	target was configured in (as is the case for at least cloudabi and
	rdos).

	x86: split gas testsuite .exp file
	The set of 32-bit-only and 64-bit-only tests has grown quite large. In
	particular when one's after only the results for the 64-bit set, having
	them live in a separate .exp file is easier / faster.

	x86: convert two pointers to (indexing) integers
	This in particular reduces the number of pointers to non-const that we
	have (and that could potentially be used for undue modification of
	state). As a result, fetch_code()'s 2nd parameter can then also become
	pointer-to-const.

	followed by another MAX_CODE_LENGTH "normal" insn bytes until we're done
	decoding), size the_buffer[] accordingly.

	Move struct dis_private down to be able to use MAX_CODE_LENGTH without
	moving its #define. While doing this also alter the order to have the
	potentially large array last.

	prefix. While maybe not overly interesting for a following real
	mnemonic, I view this as quite desirable between multiple successive
	pseudo-prefixes (bringing things in line with the other use of figure
	braces in AVX512's zeroing-masking).

	Fix scoped_value_mark not working with empty value chain
	The scoped_value_mark helper class was setting its internal
	mark value to NULL to indicate that the value chain had already
	been freed to mark.

	However, value_mark() also returns NULL if the value chain is
	empty at the time of call.

	This lead to the situation that if the value chain was empty
	at the time the scoped_value_mark was created, the class
	would not correctly clean up the state when it was destroyed,
	because it believed it had already been freed.

	I noticed this because I was setting a watchpoint very early
	in my debug session, and it was becoming a software watchpoint
	rather than hardware. Running any command that called evaluate()
	beforehand (such as 'x 0') would mean that a hardware watchpoint
	was correctly used. After some careful examination of the
	differences in execution, I noticed that values were being freed
	later in the 'bad case', which lead me to notice the issue with
	scoped_value_mark.

	This is because the operator* method of the basic_safe_iterator iterator
	wrapper returns a value_type.  So, even if the method of the underlying
	iterator (breakpoint_iterator, an intrusive_list iterator) returns a
	`breakpoint &`, the method of the wrapper returns a `breakpoint`.

	I think it would make sense for iterator wrappers such as
	basic_safe_iterator to return the exact same thing as the iterator they
	wrap.  At least, it fixes my problem.

	gdb: use intrusive_list for breakpoint locations
	Replace the hand-maintained linked lists of breakpoint locations with
	and intrusive list.

	 - Remove breakpoint::loc, add breakpoint::m_locations.

	 - Add methods for the various manipulations that need to be done on the
	   location list, while maintaining reasonably good encapsulation.

	 - bp_location currently has a default constructor because of one use
	   in hoist_existing_locations.  hoist_existing_locations now returns a
	   bp_location_list, and doesn't need the default-constructor
	   bp_location anymore, so remove the bp_location default constructor.

	 - I needed to add a call to clear_locations in delete_breakpoint to
	   avoid a use-after-free.

	 - Add a breakpoint::last_loc method, for use in
	   set_breakpoint_condition.

	bp_location_range uses reference_to_pointer_iterator, so that all
	existing callers of breakpoint::locations don't need to change right
	now.  It will be removed in the next patch.

	The rest of the changes are to adapt the call sites to use the new
	methods, of breakpoint::locations, rather than breakpoint::loc directly.

	After this commit:

	  Date:   Thu Mar 9 10:45:03 2023 +0100

	      [gdb/testsuite] Fix gdb.server/multi-ui-errors.exp for remote target

	I noticed the occasional failure in gdb.server/multi-ui-errors.exp,
	which looked like this:

	  (gdb) PASS: gdb.server/multi-ui-errors.exp: interact with GDB's main UI
	  interrupt
	  (gdb)
	  Program received signal SIGINT, Interrupt.
	  0x00007ffff7d501e7 in nanosleep () from /lib64/libc.so.6
	  FAIL: gdb.server/multi-ui-errors.exp: interrupt (timeout)
	  PASS: gdb.server/multi-ui-errors.exp: interrupt arrived
	  p server_pid
	  $1 = 718174
	  (gdb) PASS: gdb.server/multi-ui-errors.exp: p server_pid

	This is triggered by this code in gdb.server/multi-ui-errors.exp:

	    gdb_test "interrupt"

	    gdb_test_multiple "" "interrupt arrived" {
		-re "Program received signal SIGINT, Interrupt\\.\r\n" {
		    pass $gdb_test_name
		}
	    }

	The problem here is that the first interrupt will trigger the prompt
	to be printed, and then, after some time the inferior will be
	interrupted.

	However the default pattern for gdb_test includes a '$' end anchor.
	If expect sees the prompt with nothing following it then everything is
	fine, and the test passes.

	However, if the interrupt is quick and so what expect sees is this:

	  (gdb)
	  Program received signal SIGINT, Interrupt.
	  0x00007ffff7d501e7 in nanosleep () from /lib64/libc.so.6

	In this case the end anchor means that the gdb_test fails to match,
	and eventually times out.

	Fix this by passing -no-prompt-anchor to gdb_test.

	to respect it.  This flag lets callers avoid any change to the
	passed-in block and expression PC, letting them specify the context
	exactly.  In particular, now nullptr can be used to indicate that the
	parse should not examine any local variables.

	Add PARSER_DEBUG flag
	This adds a new PARSER_DEBUG constant and changes the parser code to
	use it.  This lets us make the 'parser_debug' global 'static'.

	Rearrange parser_state
	This patch mildly rearranges parser_state, moving all the bool fields
	together.

	Boolify parser_state::comma_terminates
	parser_state::comma_terminates ought to be boolean, and changing it
	does not require any other changes.

	Simplify parser_state constructor
	This simplifies the parser_state constructor by having it accept a
	parser_flags parameter.

	Introduce and use parser flags
	This patch adds a new parser_flags type and changes the parser APIs to
	use it rather than a collection of 'int' and 'bool'.  More flags will
	be added in subsquent patches.

	Move innermost_block_tracker to expression.h
	I think parser-defs.h should hold declarations that can be used by
	parser implementations, whereas expression.h should hold declarations
	that are used by code that wants to call a parser.  Following this
	logic, this patch moves innermost_block_tracker to expression.h.

	Introduce mi_parse helper methods
	This introduces some helper methods for mi_parse that handle some of
	the details of parsing.  This approach lets us reuse them later.

	Introduce "static constructor" for mi_parse
	Change the mi_parse function to be a static method of mi_parse.  This
	lets us remove the 'set_args' setter function.

	Change mi_parse_argv to a method
	This changes mi_parse_argv to be a method of mi_parse.  This is just a
	minor cleanup.

	Use accessor for mi_parse::args
	This changes mi_parse::args to be a private member, retrieved via
	accessor.  It also changes this member to be a std::string.  This
	makes it simpler for a subsequent patch to implement different
	behavior for argument parsing.

	Use member initializers in mi_parse
	This changes mi_parse to use member initializers rather than a
	constructor.  This is easier to follow.

	Use field_signed from Python MI commands
	If an MI command written in Python includes a number in its output,
	currently that is simply emitted as a string.  However, it's
	convenient for a later patch if these are emitted using field_signed.
	This does not make a difference to ordinary MI clients.

	gdb/cli-out.c: clear_current_line shouldn't trigger pagination prompt
	clear_current_line overwrites the current line with chars_per_line
	blank spaces.  Printing the final space triggers a condition in
	pager_file::puts that causes lines_printed to be incremented.  If
	lines_printed becomes greater than or equal to lines_allowed, the
	pagination prompt will appear if enabled.

	In this case the prompt is unnecessary since after printing the final
	space clear_current_line immediately moves the cursor to the beginning
	of the line with '\r'.  A new line isn't actually started, so the prompt
	ends up being spurious.

	Additionally it's possible for gdb to crash during this pagination prompt.
	Answering the prompt with 'q' throws an exception intended to bring gdb
	back to the main event loop.  But since commit 0fea10f32746,
	clear_current_line may be called under the progress_update destructor.
	The exception will try to propagate through the destructor, causing an abort.

	To fix this, pagination is disabled for the duration for clear_current_line.
	clear_current_line is also renamed to clear_progress_notify to help
	indicate that it is a special purpose function intended for use with
	do_progress_notify.

	PR30437 aarch64: make RELA relocs idempotent
	normally RELA relocs in BFD should not consider the contents of the
	relocated place.  The aarch64 psABI is even stricter, it specifies
	(section 5.7.16) that all RELA relocs _must_ be idempotent.

	Since the inception of the aarch64 BFD backend all the relocs have a
	non-zero src_mask, and hence break this invariant.  It's normally not
	a very visible problem as one can see it only when the relocated place
	already contains a non-zero value, which usually only happens sometimes
	when using 'ld -r' (or as in the testcase when jumping through hoops to
	generate the relocations).  Or with alternative toolchains that do encode
	stuff in the relocated places with the assumption that a relocation
	to that place ignores whatever is there (as they can according to
	the psABI).

	Golang is such a toolchain and https://github.com/golang/go/issues/39927
	is ultimately caused by this problem: the testcase testGCData failing
	is caused by the garbage collection data-structure to describe a type
	containing pointers to be wrong.  It's wrong because a field that's
	supposed to contain a file-relative offset (to some gcbits) has a
	relocation applied and that relocation has an addend which also is
	already part of the go-produced object file (so the addend is
	implicitely applied twice).

	gdb/testsuite: change hardcoded assembly in gdb.arch/disp-step-insn-reloc.exp
	When testing gdb.arch/disp-step-insn-reloc.exp with clang in an x86_64
	machine, the compiled test case would segfault when returning from
	the function can_relocate_call, with a suggestion of a broken stack.
	The example assembly in the commment was the following:

	   f:
	     MOV $1, %[ok]
	     JMP end
	   set_point0:
	     CALL f ; tracepoint here.
	   end:

	And the segmentation fault happening at the final "ret" instruction of
	can_relocate_call.  Looking at the disassembled version of the later
	half of the important function, we see:

	Clang version (f starting at 11a4):
	  00000000000011ae <set_point0>:

	    401148:       c3                      retq

	The epilogue of set_point0 (11cf for clang, 401146 for gcc) is the main
	difference: GCC's version uses the leaveq instruction, which resets rsp
	based on rbp, while clang adds the same constant to rsp that it
	subtracted in the prologue.  Clang fails because the return address that
	is added by the "call f" instruction isn't accounted for.

	This commit fixes that by adding a return instruction to f, which leaves
	the rsp as the compilers would expect.

	tic54x set_arch_mach
	The tic54x backend provides its own coff_set_arch_mach, but wants to
	use the standard coff_set_section_contents.  BFD_JUMP_TABLE_WRITE
	defines both of these functions, so the code also provides a wrapper
	for coff_set_section_contents.  This is all quite OK, but I was on a
	mission to remove unnecessary declarations in coffcode.h, and on
	deleting the one for coff_set_arch_mach ran into a warning about the
	function being unused.  I could have kept that declaration with its
	ATTRIBUTE_UNUSED or written "static bool ATTRIBUTE_UNUSED" on the
	definition but the latter is not usual and looks odd to me.  So I
	had a closer look at tic54x_set_arch_mach and decided the function is
	very likely wrong to allow bfd_arch_unknown.  Thus the backend should
	be using the standard coff_set_arch_mach.

	gdb: fix post-hook execution for remote targets
	Commit b5661ff2 ("gdb: fix possible use-after-free when
	executing commands") attempted to fix possible use-after-free
	in case command redefines itself.

	Commit 37e5833d ("gdb: fix command lookup in execute_command ()")
	updated the previous fix to handle subcommands as well by using the
	original command string to lookup the command again after its execution.

	This fixed the test in gdb.base/define.exp but it turned out that it
	does not work (at least) for "target remote" and "target extended-remote".

	The problem is that the command buffer P passed to execute_command ()
	gets overwritten in dont_repeat () while executing "target remote"
	command itself:

		#0  dont_repeat () at top.c:822
		#1  0x000055555730982a in target_preopen (from_tty=1) at target.c:2483
		#2  0x000055555711e911 in remote_target::open_1 (name=0x55555881c7fe ":1234", from_tty=1, extended_p=0)
		    at remote.c:5946
		#3  0x000055555711d577 in remote_target::open (name=0x55555881c7fe ":1234", from_tty=1) at remote.c:5272
		#4  0x00005555573062f2 in open_target (args=0x55555881c7fe ":1234", from_tty=1, command=0x5555589d0490)
		    at target.c:853
		#5  0x0000555556ad22fa in cmd_func (cmd=0x5555589d0490, args=0x55555881c7fe ":1234", from_tty=1)
		    at cli/cli-decode.c:2737
		#6  0x00005555573487fd in execute_command (p=0x55555881c802 "4", from_tty=1) at top.c:688

	Therefore the second call to lookup_cmd () at line 697 fails to find
	command because the original command string is gone.

	This commit addresses this particular problem by creating a *copy* of
	original command string for the sole purpose of using it after command
	execution to lookup the command again. It may not be the most efficient
	way but it's safer given that command buffer is shared and overwritten
	in hard-to-foresee situations.

	Tested on x86_64-linux.

	gdb: Remove redundant frame switching
	547ce8f00b fixed an issue where dynamic types were not being resolved
	correctly prior to printing a value. The same issue was discovered when
	printing the value using mi-mode, which was not covered by the fix.
	Porting the fix to the mi-mode code path resolved the issue.

	However, it was discovered that a later patch series, ending
	2fc3b8a4cb8, independently fixed the issue in both the cli- and mi-mode
	code paths, making the original fix unneeded.

	This commit removes this extra frame switch and adds test coverage for
	the mi-mode scenario to protect against any future divergence in this

	gdb: safety checks in skip_prologue_using_sal
	While working on the previous patch I reverted this commit:

	  commit e86e87f77fd5d8afb3e714f1d9e09e0ff5b4e6ff
	  Date:   Tue Nov 28 16:23:32 2006 +0000

	          * symtab.c (find_pc_sect_line): Do not return a line before
	            the start of a symtab.

	When I re-ran the testsuite I saw some GDB crashes in the tests:

	  gdb.dwarf2/dw2-line-number-zero.exp
	  gdb.dwarf2/dw2-lines.exp
	  gdb.dwarf2/dw2-vendor-extended-opcode.exp

	GDB was reading beyond the end of an array in the function
	skip_prologue_using_sal.

	Now, without the above commit reverted I don't believe that this
	should ever happen.  Reverting the above commit effectively breaks
	GDB's symtab_and_line lookup, we try to find a result for an address,
	and return the wrong symtab and line-table.  In
	skip_prologue_using_sal we then walk the line table looking for an
	appropriate entry, except we never find one, and GDB just keeps going,
	wandering off the end of the array.

	However, I think adding extra protection to prevent walking off the
	end of the array is pretty cheap, and if something does go wrong in
	the future then this should prevent a random crash.

	Obviously, I have no reproducer for this, as I said, I don't think
	this should impact GDB at all, this is just adding a little extra
	caution.

	gdb/testsuite: test for a function with no line table
	This commit adds a test for the following commit:

	  commit e86e87f77fd5d8afb3e714f1d9e09e0ff5b4e6ff
	  Date:   Tue Nov 28 16:23:32 2006 +0000

	              * symtab.c (find_pc_sect_line): Do not return a line before
	              the start of a symtab.

	We have been carrying a test for that commit in the Fedora GDB tree
	since that commit was added to GDB.  I don't know why the test wasn't
	added along with the original commit, but as was written, the test is
	pretty gross, it uses objcopy to pull the .text section from an object
	file, which was then injected into another source file within a .asm
	statement...

	... these days we can just make use of the DWARF assembler to achieve
	the same results, so I've rewritten the test and think it is worth
	adding this to upstream GDB.

	The original patch was about about how we find the best symtab and
	line table entry, and what to do when GDB can't find a good match.

	The new test creates a CU with two functions, only one of which is
	covered by the line table.  With the above patch reverted GDB returns
	an invalid address.

	With the above patch reverted I did run the testsuite to see what
	other tests might already be exercising this functionality, and I
	found two tests:

	  gdb.dwarf2/dw2-step-out-of-function-no-stmt.exp
	  gdb.dwarf2/dw2-vendor-extended-opcode.exp

	These are pretty similar, they either create minimal, or no line table
	for one of the functions in the source file, and as a consequence GDB
	returns an unexpected address at some point during the test.

	However, both of those tests are really focused on other issues, so I
	think this new test does add some value.  Plus the new test is not
	large, so it's not a huge cost to also run this new test.

	differences between using gdb_printf like this and calling `warning`,
	the main one is probably that real warnings are sent to gdb_stderr,
	while the above gdb_printf call will go to gdb_stdout.

	In this commit I:

	  1. Change to call `warning`, we can drop the "warning: " prefix from
	  the string in breakpoint.c,

	  2. Update the warning text, I now start with a lower case 'e', which
	  I believe is the GDB style for warnings,

	  3. And I have included the address of the bp_location in the warning
	  messsage,

	  4. Finally, I update all the tests (2) that include this error
	  message.

	      gdb/python: extend the Python Disassembler API to allow for styling

	will fail when GDB is built with Python 3.6 or earlier.  This is
	because the error that is emitted when a function argument is missing
	changed in Python 3.7, instead of an error like this:

	  Python Exception <class 'TypeError'>: function missing required argument 'style' (pos 1)

	earlier versions of Python emit:

	  Python Exception <class 'TypeError'>: Required argument 'style' (pos 1) not found

	and the new tests didn't allow for this.

	This commit fixes this by allowing either pattern.  I've tested this

	x86: permit all relational operators in insn operands
	Oddly enough == and != were not permitted, because of '=' not having
	been listed in operand_special_chars[].

2023-05-19  Jan Beulich  <jbeulich@suse.com>

	x86: further adjust extend-to-32bit-address conditions
	While a442cac5084e ("ix86: wrap constants") helped address a number of
	inconsistencies between BFD64 and !BFD64 builds, it has also resulted in
	certain bogus uses of constants to no longer be warned about. Leverage
	the md_optimize_expr() hook to adjust when to actually truncate
	expressions to 32 bits - any involvement of binary expressions (which
	would be evaluated in 32 bits only when !BFD64) signals the need for
	doing so. Plain constants (or ones merely subject to unary operators)
	should remain un-truncated - they would be handled as bignums when
	!BFD64, and hence are okay to permit.

	To compensate
	- slightly extend optimize_imm() (to be honest I never understood why
	  the code being added - or something similar - wasn't there in the
	  first place),
	- adjust expectations of the disp-imm-32 testcase (there are now
	  warnings, as there should be for any code which won't build [warning-
	  free] when !BFD64, and Disp8/Imm8 are no longer used in the warned
	  about cases).

2023-05-19  Jan Beulich  <jbeulich@suse.com>

	gas: invoke md_optimize_expr() also for unary expressions
	Give backends a chance to see these, just as they can see binary ones.
	Most of those which use this hook already cope with NULL being passed
	for the left operand (typically because of checking the operator first).
	Adjust the two which don't.

	Take the opportunity and also document the hook.

2023-05-19  Jan Beulich  <jbeulich@suse.com>

	gas: maintain O_constant signedness in more cases
	Unary '~' doesn't really produce an unsigned result. Neither does
	subtraction (unless taking operand values into consideration). And an
	abstract operator applied to two operands which aren't both unsigned
	can't be assumed to yield an unsigned result; exceptions are
	- shifts, where only signedness of the left hand operand matters,
	- comparisons, which - unlike unary '!' - produce signed results (they
	  deliver 0 or ~0, as opposed to '!', which yields 0 or 1),
	- logical operators (yielding 0 or 1 and hence treated like unary '!').

	While doing this (specifically while extending the all/quad testcase),
	update .quad and .8byte documentation: With 64-bit architectures now
	being common, it is highly inappropriate to state that these directives
	unconditionally require bignums.

2023-05-19  Jan Beulich  <jbeulich@suse.com>

	x86: tighten extend-to-32bit-address conditions
	In a442cac5084e ("ix86: wrap constants") I made the truncation condition
	too relaxed: Any indication of a mode that's possible with BFD64 only
	should avoid the truncation. Therefore, like in the other two cases of
	calls to extend_to_32bit_address(), also check whether we're generating
	a 64-bit object.

	gdb.fortran/lbound-ubound.exp: read expected lbound and ubound from function parameters (PR 30414)
	gdb.fortran/lbound-ubound.exp reads the expected lbound and ubound
	values by reading some output from the inferior.  This is racy when
	running on boards where the inferior I/O is on a separate TTY than
	GDB's, such as native-gdbserver.

	I sometimes see this behavior:

	    (gdb) continue
	    Continuing.

	    Breakpoint 2, do_test (lb=..., ub=...) at /home/jenkins/workspace/binutils-gdb_master_linuxbuild/platform/jammy-amd64/target_board/nati
	    ve-gdbserver/src/binutils-gdb/gdb/testsuite/gdb.fortran/lbound-ubound.F90:45
	    45        print *, ""   ! Test Breakpoint
	    (gdb) Remote debugging from host ::1, port 37496

	     Expected GDB Output:

	    LBOUND = (-8, -10)
	    UBOUND = (-1, -2)
	    APB: Run a test here
	    APB: Expected lbound '(-8, -10)'
	    APB: Expected ubound ''

	What happened is that expect read the output from GDB before the output
	from the inferior, triggering this gdb_test_multiple clause:

	    -re "$gdb_prompt $" {
	        set found_prompt true

	        if {$found_dealloc_breakpoint
	            || ($expected_lbound != "" && $expected_ubound != "")} {
	            # We're done.
	        } else {
	            exp_continue
	        }
	    }

	So it set found_prompt, but the gdb_test_multiple kept going because
	found_dealloc_breakpoint is false (this is the flag indicating that the
	test is finished) and we still don't have expected_lbound and
	expected_ubound.  Then, expect reads in the inferior I/O, triggering
	this clause:

	    -re ".*LBOUND = (\[^\r\n\]+)\r\n" {
	        set expected_lbound $expect_out(1,string)
	        if {!$found_prompt} {
	            exp_continue
	        }
	    }

	This sets expected_lbound, but since found_prompt is true, we don't do
	exp_continue, and exit the gdb_test_multiple, without having an
	expected_ubound.

	Change the test to read the values from the lb and ub function
	parameters instead.  As far as I understand, this still exercises what
	we want to test.  These variables contain the return values of the
	lbound and ubound functions as computed by the program.  We'll use them
	to check the return values of the lbound and ubound functions as
	computed by GDB.

	gdb/elfread.c: Add plt symbol check for _PROCEDURE_LINKAGE_TABLE_
	In the current code, when execute the following test on LoongArch:

	$ make check-gdb TESTS="gdb.base/gnu-ifunc.exp"
	 === gdb Summary ===

	 # of expected passes           111
	 # of unexpected failures       62

	According to IFUNC's working process [1]. first time the IFUNC function
	is called, the dynamic linker will not simply fill the .got.plt entry
	with the actual address of IFUNC symbol, it will call the IFUNC resolver
	function and take the return address, uses it as the sym-bound address
	and puts it in the .got.plt entry. Initial address in .got.plt entry is
	not a real function addresss. Depending on the compiler implementation,
	some different addresses will be filled in. Most architectures will use
	a .plt entry address to fill in the corresponding .got.plt entry.

	In gdb, elf_gnu_ifunc_resolve_addr() will be called to return a real
	IFUNC function addresss. First check to see if the real address for
	the IFUNC symbol has been resolved by the following function:

	elf_gnu_ifunc_resolve_name (const char *name, CORE_ADDR *addr_p)
	{
	  if (elf_gnu_ifunc_resolve_by_cache (name, addr_p))
	    return true;

	  if (elf_gnu_ifunc_resolve_by_got (name, addr_p))
	    return true;

	  return false;
	}

	in elf_gnu_ifunc_resolve_by_got(), it gets the contents of the
	.got.plt entry and determines if the contents is the correct address
	by calling elf_gnu_ifunc_record_cache(). Based on the IFUNC working
	principle analysis above, the address filled in the .got.plt entry is
	not the actual target function address initially, it would be a .plt
	entry address corresponding symbol like *@plt. In this case, gdb just
	go back to execute the resolver function and puts the return address
	in the .got.plt entry. After that, gdb can get a real ifun address via
	.got.plt entry.

	On LoongArch, initially, each address filled in the .got.plt entries
	is the first .plt entry address. Some architectures such as LoongArch
	define the symbol _PROCEDURE_LINKAGE_TABLE_ at the start of the .plt
	section. This symbol is the first plt entry, so gdb needs to check
	this symbol in elf_gnu_ifunc_record_cache().

	On LoongArch .got.plt and .plt section as follow:

	$objdump -D gdb/testsuite/outputs/gdb.base/gnu-ifunc/gnu-ifunc-0-0-0

	Special case "&str" in Rust parser
	"&str" is an important type in Rust -- it's the type of string
	literals.  However, the compiler puts it in the DWARF in a funny way.
	The slice itself is present and named "&str".  However, the Rust
	parser doesn't look for types with names like this, but instead tries
	to construct them from components.  In this case it tries to make a
	pointer-to-"str" -- but "str" isn't always available, and in any case
	that wouldn't yield the best result.

	This patch adds a special case for &str.

	gdb/testsuite: fix regressions in break-main-file-remove-fail.exp
	After this commit:

	  commit a68f7e9844208ad8cd498f89b5100084ece7d0f6
	  Date:   Tue May 9 10:28:42 2023 +0100

	      gdb/testsuite: extend special '^' handling to gdb_test_multiple

	buildbot notified me of a regression on s390 in the test:

	  gdb.base/break-main-file-remove-fail.exp

	the failure looks like this:

	  print /d ((int (*) (void *, size_t)) munmap) (16781312, 4096)
	  warning: Error removing breakpoint 0
	  $2 = 0
	  (gdb) FAIL: gdb.base/break-main-file-remove-fail.exp: cmdline: get integer valueof "((int (*) (void *, size_t)) munmap) (16781312, 4096)"

	On the mailing list it has been reported that this failure also
	impacts arm, aarch64, and possibly ppc/ppc64 too.

	The above commit changed get_integer_valueof so that no output is
	expected between the command and the '$2 = 0' line.  In this case the
	'warning: Error removing breakpoint 0' output is causing the
	get_integer_valueof call to fail.

	The reason for this warning is that this test deliberately calls
	munmap on a page of the inferior's code.  The test is checking that
	GDB can handle the situation where a s/w breakpoint can't be
	removed (due to the page no longer being readable/writable).

	The test that is supposed to trigger the warning is later in the test
	script when we delete a breakpoint.

	So why do some targets trigger the warning earlier during the inferior
	call?

	The impacted targets use AT_ENTRY_POINT as their strategy for handling
	inferior calls, that is, the trampoline that calls the inferior
	function is placed at the program's entry point, e.g. often the _start
	label.

	If this location happens to be on the same page as the page that the
	test script unmaps then, when the inferior function call returns, GDB
	will not be able to remove the temporary breakpoint that is inserted
	to catch the inferior function call returning!  As a result we end up
	seeing the warning earlier than expected.

	I did wonder if this means I should relax the pattern in
	get_integer_valueof - just accept that there might be additional
	output from GDB which we should ignore.

	However, I don't think this the right way to go.  With the change in
	a68f7e984420 we are now stricter for GDB emitting additional,
	unexpected, output, and I think that is a good thing.

	So, I think, in this case, in order to handle the possible extra
	output, we should implement something like get_integer_valueof
	directly in the gdb.base/break-main-file-remove-fail.exp test script.
	This local version will handle the possible warning output.

	After this the test should pass again on the impacted targets.

	gdb/python: extend the Python Disassembler API to allow for styling
	This commit extends the Python Disassembler API to allow for styling
	of the instructions.

	Before this commit the Python Disassembler API allowed the user to do
	two things:

	  - They could intercept instruction disassembly requests and return a
	    string of their choosing, this string then became the disassembled
	    instruction, or

	  - They could call builtin_disassemble, which would call back into
	    libopcode to perform the disassembly.  As libopcode printed the
	    instruction GDB would collect these print requests and build a
	    string.  This string was then returned from the builtin_disassemble
	    call, and the user could modify or extend this string as needed.

	Neither of these approaches allowed for, or preserved, disassembler
	styling, which is now available within libopcodes for many of the more
	popular architectures GDB supports.

	This commit aims to fill this gap.  After this commit a user will be
	able to do the following things:

	  - Implement a custom instruction disassembler entirely in Python
	    without calling back into libopcodes, the custom disassembler will
	    be able to return styling information such that GDB will display
	    the instruction fully styled.  All of GDB's existing style
	    settings will affect how instructions coming from the Python
	    disassembler are displayed in the expected manner.

	  - Call builtin_disassemble and receive a result that represents how
	    libopcode would like the instruction styled.  The user can then
	    adjust or extend the disassembled instruction before returning the
	    result to GDB.  Again, the instruction will be styled as expected.

	To achieve this I will add two new classes to GDB,
	DisassemblerTextPart and DisassemblerAddressPart.

	Within builtin_disassemble, instead of capturing the print calls from
	libopcodes and building a single string, we will now create either a
	text part or address part and store these parts in a vector.

	The DisassemblerTextPart will capture a small piece of text along with
	the associated style that should be used to display the text.  This
	corresponds to the disassembler calling
	disassemble_info::fprintf_styled_func, or for disassemblers that don't
	support styling disassemble_info::fprintf_func.

	The DisassemblerAddressPart is used when libopcodes requests that an
	address be printed, and takes care of printing the address and
	associated symbol, this corresponds to the disassembler calling
	disassemble_info::print_address_func.

	These parts are then placed within the DisassemblerResult when
	builtin_disassemble returns.

	Alternatively, the user can directly create parts by calling two new
	methods on the DisassembleInfo class: DisassembleInfo.text_part and
	DisassembleInfo.address_part.

	Having created these parts the user can then pass these parts when
	initializing a new DisassemblerResult object.

	Finally, when we return from Python to gdbpy_print_insn, one way or
	another, the result being returned will have a list of parts.  Back in
	GDB's C++ code we walk the list of parts and call back into GDB's core
	to display the disassembled instruction with the correct styling.

	The new API lives in parallel with the old API.  Any existing code
	that creates a DisassemblerResult using a single string immediately
	creates a single DisassemblerTextPart containing the entire
	instruction and gives this part the default text style.  This is also
	what happens if the user calls builtin_disassemble for an architecture
	that doesn't (yet) support libopcode styling.

	This matches up with what happens when the Python API is not involved,
	an architecture without disassembler styling support uses the old
	libopcodes printing API (the API that doesn't pass style info), and
	GDB just prints everything using the default text style.

	The reason that parts are created by calling methods on
	DisassembleInfo, rather than calling the class constructor directly,
	is DisassemblerAddressPart.  Ideally this part would only hold the
	address which the part represents, but in order to support backwards
	compatibility we need to be able to convert the
	DisassemblerAddressPart into a string.  To do that we need to call
	GDB's internal print_address function, and to do that we need an
	gdbarch.

	What this means is that the DisassemblerAddressPart needs to take a
	gdb.Architecture object at creation time.  The only valid place a user
	can pull this from is from the DisassembleInfo object, so having the
	DisassembleInfo act as a factory ensures that the correct gdbarch is
	passed over each time.  I implemented both solutions (the one
	presented here, and an alternative where parts could be constructed
	directly), and this felt like the cleanest solution.

	gdb/python: rework how the disassembler API reads the result object
	This commit is a refactor ahead of the next change which will make
	disassembler styling available through the Python API.

	Unfortunately, in order to make the styling support available, I think
	the easiest solution is to make a very small change to the existing
	API.

	The current API relies on returning a DisassemblerResult object to
	represent each disassembled instruction.  Currently GDB allows the
	DisassemblerResult class to be sub-classed, which could mean that a
	user tries to override the various attributes that exist on the
	DisassemblerResult object.

	This commit removes this ability, effectively making the
	DisassemblerResult class final.

	Though this is a change to the existing API, I'm hoping this isn't
	going to cause too many issues:

	  - The Python disassembler API was only added in the previous release
	    of GDB, so I don't expect it to be widely used yet, and

	  - It's not clear to me why a user would need to sub-class the
	    DisassemblerResult type, I allowed it in the original patch
	    because at the time I couldn't see any reason to NOT allow it.

	Having prevented sub-classing I can now rework the tail end of the
	gdbpy_print_insn function; instead of pulling the results out of the
	DisassemblerResult object by calling back into Python, I now cast the
	Python object back to its C++ type (disasm_result_object), and access
	the fields directly from there.  In later commits I will be reworking
	the disasm_result_object type in order to hold information about the
	styled disassembler output.

	The tests that dealt with sub-classing DisassemblerResult have been
	removed, and a new test that confirms that DisassemblerResult can't be
	sub-classed has been added.

	Fix regression due to Pragma Import series
	A co-worker here at AdaCore discovered that the Pragma Import series
	caused a rgression.  When debugging gnat1, gdb started asking for
	overload resolution like:

	(gdb) call pp(n)
	Multiple matches for pp
	[0] cancel
	[1] pp (types.union_id) at ../../gcc/gcc/ada/treepr.adb:511
	[2] treepr.pp (types.union_id) at ../../gcc/gcc/ada/treepr.adb:511

	This worked before the series, and is strange anyway, because the
	matches refer to the same function.

	This patch adds a test case for this situation and fixes the bug by
	pruning identical functions in remove_extra_symbols.

2023-05-12  Tom Tromey  <tromey@adacore.com>

	Use bool and early loop exit in remove_extra_symbols
	This changes remove_extra_symbols to use bool rather than int, and
	changes the nested loops to exit early when "remove_p" is set.

	Use reference parameter in remove_extra_symbols
	Changing ada-lang.c:remove_extra_symbols to take a reference parameter
	makes the code a bit easier to read, by replacing "(*syms)" with plain
	"syms".

	Handle Ada Pragma Import and Pragma Export
	Ada can import C APIs and also export Ada constructs to C via Pragma
	Import and Pragma Export.  This patch adds support for these to gdb,
	by arranging to either defer some aspects of a symbol to the
	underlying C symbol (for Import) or by introducing a second symbol
	(for Export).  A somewhat tricky approach is needed, both because gdb
	doesn't generally handle symbol aliasing, and because Ada treats
	symbol names in an unusual way (as compared to the rest of gdb).

	Introduce symbol_block_ops::get_block_value
	This adds a new callback to symbol_block_ops.  This callback lets a
	LOC_BLOCK symbol implement its own function to find the underlying
	block.

	Define symbol::value_block separately
	This moves the definition of symbol::value_block outside of the class.
	A subsequent patch will change this method to use SYMBOL_BLOCK_OPS,
	and it seemed simplest to move this method out-of-line, and cleaner to
	do this as a separate change.

	Bump MAX_SYMBOL_IMPLS
	A subsequent patch will introduce more aclass registrations, causing
	the number to go over the current maximum.  This bumps the number.
	Note that there's a separate static assert that ensures that this
	number doesn't get too large for the field size in the symbol.

	Introduce lookup_minimal_symbol_linkage
	This introduces a new function, lookup_minimal_symbol_linkage, and
	refactors a couple other existing functions to call it.  This function
	will be used in a subsequent patch.

	Some small improvements to the Python Disassembler API documentation:

	  * Be consistent about using the package scope in the @deftp lines,

	  * Rework the description of the DisassemblerResult class to include
	    mention of builtin_disassemble.

	gdb/testsuite: extend special '^' handling to gdb_test_multiple
	The commit:

	  commit 08ec06d6440745ef9204d39197aa1e732df41056
	  Date:   Wed Mar 29 10:41:07 2023 +0100

	      gdb/testsuite: special case '^' in gdb_test pattern

	Added some special handling of '^' to gdb_test -- a leading '^' will
	cause the command regexp to automatically be included in the expected
	output pattern.

	It was pointed out that the '-wrap' flag of gdb_test_multiple is
	supposed to work in the same way as gdb_test, and that the recent
	changes for '^' had not been replicated for gdb_test_multiple.  This
	patch addresses this issue.

	So, after this commit, the following two constructs should have the
	same meaning:

	  gdb_test "command" "^output" "test name"

	  gdb_test_multiple "command" "test name" {
	    -re -wrap "^output" {
	      pass $gdb_test_name
	    }
	  }

	In both cases the '^' will case gdb.exp to inject a regexp that
	matches 'command' after the '^' and before the 'output', this is in
	addition to adding the $gdb_prompt pattern after 'output' in the
	normal way.

	The special '^' handling is only applied when '-wrap' is used, as this
	is the only mode that aims to mimic gdb_test.

	While working on this patch I realised that I could actually improve
	the logic for the special '^' handling in the case where the expected
	output pattern is empty.  I replicated these updates for both gdb_test
	and gdb_test_multiple in order to keep these two paths in sync.

	There were a small number of tests that needed adjustment after this
	change, mostly just removing command regexps that are now added
	automatically, but the gdb.base/settings.exp case was a little weird
	as it turns out trying to match a single blank line is probably harder
	now than it used to be -- still, I suspect this is a pretty rare case,
	so I think the benefits (improved anchoring) outweigh this small
	downside (IMHO).

	gdb: fix error message for $_gdb_maint_setting
	I spotted this behaviour:

	  (gdb) p $_gdb_maint_setting("xxx")
	  First argument of $_gdb_maint_setting must be a valid setting of the 'show' command.

	Notice that GDB claims I need to use a setting from the 'show'
	command, which isn't correct for $_gdb_maint_setting, in this case I
	need to use a setting from 'maintenance show'.

	This same issue is present for $_gdb_maint_setting_str.

	This commit fixes this minor issue.

	[gdb/testsuite] Fix gdb.dwarf2/opt-out-not-implptr.exp for -m32
	When running test-case gdb.dwarf2/opt-out-not-implptr.exp with target board
	unix/-m32 we have:
	...
	(gdb) print noptr^M
	$1 = {0, <optimized out>, <optimized out>, <optimized out>}^M
	(gdb) FAIL: gdb.dwarf2/opt-out-not-implptr.exp: print noptr
	...

	The problem happens when evaluating this dwarf expression:
	...
	  <45> DW_AT_location : 13 byte block: 10 86 ea d7 d0 96 8e cf 92 5c 9f 93 8 \
	  (DW_OP_constu: 6639779683436459270; DW_OP_stack_value; DW_OP_piece: 8)
	...

	The DW_OP_constu pushes a value with "generic type" on to the DWARF stack, and
	the "generic type" has the size of an address on the target machine, which for
	target board unix/-m32 is 4 bytes.  Consequently, the constant is abbreviated.

	Next, the DW_OP_piece declares that the resulting 4-byte value is 8 bytes
	large, and we hit this clause in rw_pieced_value:
	...
	            /* Use zeroes if piece reaches beyond stack value.  */
	            if (p->offset + p->size > stack_value_size_bits)
	              break;
	...
	and consequently get a zero.

	We could just add require is_target_64 to the test-case, but instead, add a
	32-bit case and require is_target_64 just for the 64-bit case.

	Tested on x86_64-linux.

	[gdb/testsuite] Make is_64_target more robust
	I ran test-case gdb.dwarf2/opt-out-not-implptr.exp with make-check-all.sh, and
	with target board dwarf64 ran into:
	...
	FAIL: gdb.dwarf2/opt-out-not-implptr.exp: print noptr
	...
	due to is_target_64 failing because of:
	...
	builtin_spawn -ignore SIGHUP gcc -fno-stack-protector \
	  -fdiagnostics-color=never -w -c -gdwarf64 -g -o is_64_target.o \
	  is_64_target.c^M
	gcc: error: '-gdwarf64' is ambiguous; use '-gdwarf-64' for DWARF version or \
	  '-gdwarf -g64' for debug level^M
	compiler exited with status 1
	...

	The FAIL is the same FAIL I run into with target board unix/-m32: is_target_64
	fails for both cases.

	The reason that is_target_64 is failing for target board dwarf64, is because
	of using system compiler 7.5.0 which doesn't support -gdwarf64.

	Fix this by making is_target_64 use nodebug instead of debug for compilation.

	Tested on x86_64-linux.

	[gdb/cli] Fix wrapping for TERM=ansi
	I. Auto-detected width (xterm vs. ansi)

	Say we have a terminal with a width of 40 chars:
	...
	$ echo $COLUMNS
	40
	...

	With TERM=xterm, we report a width of 40 chars:
	...
	$ TERM=xterm gdb
	(gdb) show width
	Number of characters gdb thinks are in a line is 40.
	...

	And with TERM=ansi, a width of 39 chars:
	...
	$ TERM=ansi gdb
	(gdb) show width
	Number of characters gdb thinks are in a line is 39.
	...

	Gdb uses readline to auto-detect screen size, and readline decides in the
	TERM=ansi case that the terminal does not have reliable auto-wrap, and
	consequently decides to hide the last terminal column from the readline user
	(in other words GDB), hence we get 39 instead of 40.

	II. Types of wrapping

	Looking a bit more in detail inside gdb, it seems there are two types of
	wrapping:
	- readline wrapping (in other words, prompt edit wrapping), and
	- gdb output wrapping (can be observed by issuing "info sources").
	  This type of wrapping attempts to wrap some of the gdb output earlier
	  than the indicated width, to not break lines in inconvenient places.

	III. Readline wrapping, auto-detected screen size

	Let's investigate readline wrapping with the auto-detected screen widths.

	First, let's try with xterm:
	...
	$ TERM=xterm gdb
	(gdb) 7890123456789012345678901234567890
	123
	...
	That looks as expected, wrapping occurs after 40 chars.

	Now, let's try with ansi:
	...
	$ TERM=ansi gdb
	(gdb) 78901234567890123456789012345678
	90123
	...
	It looks like wrapping occurred after 38, while readline should be capable of
	wrapping after 39 chars.

	This is caused by readline hiding the last column, twice.

	In more detail:
	- readline detects the screen width: 40,
	- readline hides the last column, setting the readline screen width to 39,
	- readline reports 39 to gdb as screen width,
	- gdb sets its width setting to 39,
	- gdb sets readline screen width to 39,
	- readline hides the last column, again, setting the readline screen width to
	  38.

	This is reported as PR cli/30346.

	IV. gdb output wrapping, auto-detected screen size

	Say we set the terminal width to 56. With TERM=xterm, we have:
	...
	/home/abuild/rpmbuild/BUILD/glibc-2.31/csu/elf-init.c,
	/data/vries/hello.c,
	...
	but with TERM=ansi:
	...
	/home/abuild/rpmbuild/BUILD/glibc-2.31/csu/elf-init.c, /
	data/vries/hello.c,
	...

	So what happened here?  With TERM=ansi, the width setting is auto-detected to
	55, and gdb assumes the terminal inserts a line break there, which it doesn't
	because the terminal width is 56.

	This is reported as PR cli/30411.

	V. Fix PRs

	Fix both mentioned PRs by taking into account the hidden column when readline
	reports the screen width in init_page_info, and updating chars_per_line
	accordingly.

	Note that now we report the same width for both TERM=xterm and TERM=ansi,
	which is much clearer.

	The point where readline respectively expects or ensures wrapping is still
	indicated by "maint info screen", for xterm:
	...
	Number of characters readline reports are in a line is 40.
	...
	and ansi:
	...
	Number of characters readline reports are in a line is 39.
	...

	VI. Testing

	PR cli/30346 is covered by existing regression tests gdb.base/wrap-line.exp
	and gdb.tui/wrap-line.exp, so remove the KFAILs there.

	I didn't manage to come up with a regression test for PR cli/30411.  Perhaps
	that would be easier if we had a maintenance command that echoes its arguments
	while applying gdb output wrapping.

	Tested on x86_64-linux.

	gas: equates of registers
	There are two problems: symbol_equated_p() doesn't recognize equates of
	registers, and S_CAN_BE_REDEFINED() goes by section rather than by
	expression type. Both together undermine .eqv and .equiv clearly meaning
	to guard the involved symbols against re-definition (both ways).

	To compensate pseudo_set() now using O_symbol and S_CAN_BE_REDEFINED()
	now checking for O_register,
	- for targets creating register symbols through symbol_{new,create}() ->
	  symbol_init() -> S_SET_VALUE() (alpha, arc, dlx, ia64, m68k, mips,
	  mmix, tic4x, tic54x, plus anything using cgen or itbl-ops), have
	  symbol_init() set their expressions to O_register,
	- x86'es parse_register() also can't go by section anymore when
	  trying to "look through" equates; probably symbol_equated_p() should
	  have been used there from the beginning, if only that had worked for
	  equates of registers,
	- various targets need to "look through" equates when parsing insn
	  operands (which also helps transitive forward equates); perhaps even
	  more ought to, but many don't look to consider the possibility of
	  register equates in the first place.

	This was uncovered by code reported in PR gas/30274 (duplicating
	PR gas/30272), except that there .eqv was used when really .equ was
	meant. Therefore that bug report is addressed here only in so far as
	gas wouldn't crash anymore; the code there still won't assemble
	successfully, just that now the issues there are properly diagnosed.

	Do not print <synthetic pointer> when piece is optimized out
	A user reported a bug where printing a certain array of integer types
	would result in the nonsensical:

	(gdb) p l_126
	$1 = {6639779683436459270, <synthetic pointer>, <synthetic pointer>, <synthetic pointer>}

	I tracked this down to some issues in the DWARF expression code.
	First, check_pieced_synthetic_pointer did not account for the
	situation where a location expression does not describe all the bits
	of a value -- in this case it returned true, meaning there is a
	synthetic pointer, but in fact these bits are optimized out.  (It
	turns out this incorrect output had already been erroneously tested
	for as well.)

	Next, rw_pieced_value did not mark these bits as optimized-out,
	either.

	gdb/testsuite: Match file size in gdb.debuginfod/crc_mismatch.exp

	Disable out-of-scope watchpoints
	Currently, when a local software watchpoint goes out of scope, GDB sets
	the watchpoint's disposition to `delete at next stop' and then normal
	stops (i.e., stop and wait for the next GDB command). When GDB normal
	stops, it automatically deletes the breakpoints with their disposition
	set to `delete at next stop'.

	Suppose a Python script decides not to normal stop when a local
	software watchpoint goes out of scope, the watchpoint will not be
	automatically deleted even when its disposition is set to
	`delete at next stop'.

	Since GDB single-steps the program and tests the watched expression
	after each instruction, not deleting the watchpoint causes the
	watchpoint to be hit many more times than it should, as reported in
	PR python/29603.

	This was happening because the watchpoint is not deleted or disabled
	when going out of scope.

	This commit fixes this issue by disabling the watchpoint when going out
	of scope. It also adds a test to ensure this feature isn't regressed in
	the future.

	Calling `breakpoint_auto_delete' on all kinds of stops (in
	`fetch_inferior_event') seem to solve this issue, but is in fact
	inappropriate, since `breakpoint_auto_delete' goes over all breakpoints
	instead of just going through the bpstat chain (which only contains the
	breakpoints that were hit right now).

	Add LDPT_REGISTER_CLAIM_FILE_HOOK_V2 linker plugin hook [GCC PR109128]
	This is one part of the fix for GCC PR109128, along with a
	corresponding GCC change.  Without this patch, what happens in the
	linker, when an unused object in a .a file has offload data, is that
	elf_link_is_defined_archive_symbol calls bfd_link_plugin_object_p,
	which ends up calling the plugin's claim_file_handler, which then
	records the object as one with offload data. That is, the linker never
	decides to use the object in the first place, but use of this _p
	interface (called as part of trying to decide whether to use the
	object) results in the plugin deciding to use its offload data (and a
	consequent mismatch in the offload data present at runtime).

	The new hook allows the linker plugin to distinguish calls to
	claim_file_handler that know the object is being used by the linker
	(from ldmain.c:add_archive_element), from calls that don't know it's
	being used by the linker (from elf_link_is_defined_archive_symbol); in
	the latter case, the plugin should avoid recording the object as one
	with offload data.

	gdb/rust: fix crash for expression debug with strings
	While working on another patch I did this:

	  (gdb) set debug expression 1
	  (gdb) set language rust
	  (gdb) p "foo"
	  Operation: OP_AGGREGATE
	   Type: &str

	  Fatal signal: Segmentation fault
	  ... etc ...

	The problem is that the second field of the rust_aggregate_operation
	is created as a nullptr, this can be seen in rust-parse.c. in the
	function rust_parser::parse_string().

	However, in expop.h, in the function dump_for_expression, we make the
	assumption that the expressions will never be nullptr.

	I did consider moving the nullptr handling into a new function
	rust_aggregate_operation::dump, however, as the expression debug
	dumping code is not exercised as much as it might be, I would rather
	that this code be hardened and able to handle a nullptr without
	crashing, so I propose that we add nullptr handling into the general
	dump_for_expression function.  The behaviour is now:

	  (gdb) set debug expression 1
	  (gdb) set language rust
	  (gdb) p "foo"
	  Operation: OP_AGGREGATE
	   Type: &str
	   nullptr

	      String: foo
	    String: length
	    Operation: OP_LONG
	     Type: usize
	     Constant: 3
	  evaluation of this expression requires the target program to be active
	  (gdb)

	There's a new test to check for this case.

	There are a couple of problems with compact-source.

	First of all the documentation mentions:
	...
	The default display uses more space for line numbers and starts the
	source text at the next tab stop; the compact display uses only as
	much space as is needed for the line numbers in the current file, and
	only a single space to separate the line numbers from the source.
	...

	The bit about the default display and the next tab stop looks incorrect.  The
	source doesn't start at a tab stop, instead it uses a single space to separate
	the line numbers from the source.

	Then the documentation mentions that there's single space in the compact
	display, but evidently that's missing.

	Then there's the fact that the line numbers "10" and "11" are both abbreviated
	to "1" in the compact case.

	The abbreviation is due to allocating space for <lines in source>, which is
	8 for this example, and takes a single digit.  The line numbers though
	continue past the end of the file, so fix this by allocating space for
	max (<lines in source>, <last line in window>), which in this example takes 2
	digits.

	The missing space is due to some confusion about what the "1" here in
	tui_source_window::set_contents represent:
	...
	      double l = log10 ((double) offsets->size ());
	      m_digits = 1 + (int) l;
	...

	It could be the trailing space that's mentioned in tui-source.h:
	...
	  /* How many digits to use when formatting the line number.  This
	     includes the trailing space.  */
	  int m_digits;
	...

	Then again, it could be part of the calculation for the number of digits
	needed for printing.  With this minimal example:
	...
	int main () {
	  for (int i = 8; i <= 11; ++i) {
	    double l = log10 ((double) i);
	    printf ("%d %d\n", i, (int)l);
	  }
	  return 0;
	}
	...
	we get:
	...
	$ ./a.out
	8 0
	9 0
	10 1
	11 1
	...
	which shows that the number of digits needed for printing i is
	"1 + (int)log10 ((double) i)".

	Fix this by introducing named variables needed_digits and trailing_space, each
	adding 1.

	With the fixes, we get for compact-source on:
	...
	+-./data/hello.c-----------------------+
	|___05_{                               |
	|___06_  printf ("hello\n");           |
	|___07_  return 0;                     |
	|___08_}                               |
	|___09_                                |
	|___10_                                |
	|___11_                                |
	|...

	Also fix the documentation and help text to actually match effect of
	compact-source.

	gdb: fix use-after-free in check_longjmp_breakpoint_for_call_dummy
	Commit 7a8de0c33019 ("Remove ALL_BREAKPOINTS_SAFE") introduced a
	use-after-free in the breakpoints iterations (see below for full ASan
	report).  This makes gdb.base/stale-infcall.exp fail when GDB is build
	with ASan.

	check_longjmp_breakpoint_for_call_dummy iterates on all breakpoints,
	possibly deleting the current breakpoint as well as related breakpoints.
	The problem arises when a breakpoint in the B->related_breakpoint chain
	is also B->next.  In that case, deleting that related breakpoint frees
	the breakpoint that all_breakpoints_safe has saved.

	The old code worked around that by manually changing B_TMP, which was
	the next breakpoint saved by the "safe iterator":

		while (b->related_breakpoint != b)
		  {
		    if (b_tmp == b->related_breakpoint)
		      b_tmp = b->related_breakpoint->next;
		    delete_breakpoint (b->related_breakpoint);
		  }

	(Note that this seemed to assume that b->related_breakpoint->next was
	the same as b->next->next, not sure this is guaranteed.)

	The new code kept the B_TMP variable, but it's not useful in that
	context.  We can't go change the next breakpoint as saved by the safe
	iterator, like we did before.  I suggest fixing that by saving the
	breakpoints to delete in a map and deleting them all at the end.

	Here's the full ASan report:

	gdb/python: add mechanism to manage Python initialization functions
	Currently, when we add a new python sub-system to GDB,
	e.g. py-inferior.c, we end up having to create a new function like
	gdbpy_initialize_inferior, which then has to be called from the
	function do_start_initialization in python.c.

	In some cases (py-micmd.c and py-tui.c), we have two functions
	gdbpy_initialize_*, and gdbpy_finalize_*, with the second being called
	from finalize_python which is also in python.c.

	This commit proposes a mechanism to manage these initialization and
	finalization calls, this means that adding a new Python subsystem will
	no longer require changes to python.c or python-internal.h, instead,
	the initialization and finalization functions will be registered
	directly from the sub-system file, e.g. py-inferior.c, or py-micmd.c.

	The initialization and finalization functions are managed through a
	new class gdbpy_initialize_file in python-internal.h.  This class
	contains a single global vector of all the initialization and
	finalization functions.

	In each Python sub-system we create a new gdbpy_initialize_file
	object, the object constructor takes care of registering the two
	callback functions.

	Now from python.c we can call static functions on the
	gdbpy_initialize_file class which take care of walking the callback
	list and invoking each callback in turn.

	To slightly simplify the Python sub-system files I added a new macro
	GDBPY_INITIALIZE_FILE, which hides the need to create an object.  We
	can now just do this:

	  GDBPY_INITIALIZE_FILE (gdbpy_initialize_registers);

	One possible problem with this change is that there is now no
	guaranteed ordering of how the various sub-systems are initialized (or
	finalized).  To try and avoid dependencies creeping in I have added a
	use of the environment variable GDB_REVERSE_INIT_FUNCTIONS, this is
	the same environment variable used in the generated init.c file.

	Just like with init.c, when this environment variable is set we
	reverse the list of Python initialization (and finalization)
	functions.  As there is already a test that starts GDB with the
	environment variable set then this should offer some level of
	protection against dependencies creeping in - though for full
	protection I guess we'd need to run all gdb.python/*.exp tests with
	the variable set.

	I have tested this patch with the environment variable set, and saw no
	regressions, so I think we are fine right now.

	One other change of note was for gdbpy_initialize_gdb_readline, this
	function previously returned void.  In order to make this function
	have the correct signature I've updated its return type to int, and we
	now return 0 to indicate success.

	All of the other initialize (and finalize) functions have been made
	static within their respective sub-system files.

	There should be no user visible changes after this commit.

	gdb/testsuite: more newline pattern cleanup
	After this commit:

	  commit e2f620135d92f7cd670af4e524fffec7ac307666
	  Date:   Thu Mar 30 13:26:25 2023 +0100

	      gdb/testsuite: change newline patterns used in gdb_test

	It was pointed out in PR gdb/30403 that the same patterns can be found
	in other lib/gdb.exp procs and that it would probably be a good idea
	if these procs remained in sync with gdb_test.  Actually, the bug
	specifically calls out gdb_test_multiple when using with '-wrap', but
	I found a couple of other locations in gdb_continue_to_breakpoint,
	gdb_test_multiline, get_valueof, and get_local_valueof.

	In all these locations one or both of the following issues are
	addressed:

	  1. A leading pattern of '[\r\n]*' is pointless.  If there is a
	  newline it will be matched, but if there is not then the testsuite
	  doesn't care.  Also, as expect is happy to skip non-matched output
	  at the start of a pattern, if there is a newline expect is happy to
	  skip over it before matching the rest.  As such, this leading
	  pattern is removed.

	  2. Using '\[\r\n\]*$gdb_prompt' means that we will swallow
	  unexpected blank lines at the end of a command's output, but also,
	  if the pattern from the test script ends with a '\r', '\n', or '.'
	  then these will partially match the trailing newline, with the
	  remainder of the newline matched by the pattern from gdb.exp.  This
	  split matching doesn't add any value, it's just something that has
	  appeared as a consequence of how gdb.exp was originally written.  In
	  this case the '\[\r\n\]*' is replaced with '\r\n'.

	I've rerun the testsuite and fixed the regressions that I saw, these
	were places where GDB emits a blank line at the end of the command
	output, which we now need to explicitly match in the test script, this
	was for:

	  gdb.dwarf2/dw2-out-of-range-end-of-seq.exp
	  gdb.guile/guile.exp
	  gdb.python/python.exp

	Or a location where the test script was matching part of the newline
	sequence, while gdb.exp was previously matching the remainder of the
	newline sequence.  Now we rely on gdb.exp to match the complete
	newline sequence, this was for:

	  gdb.base/commands.exp

	gdb/testsuite: tighten patterns in build-id-no-debug-warning.exp
	Tighten the expected output pattern in the test script:

	  gdb.debuginfod/build-id-no-debug-warning.exp

	While working on some other patch I broke GDB such that this warning:

	  warning: "FILENAME": separate debug info file has no debug info

	(which is generated in build-id.c) didn't actually include the
	FILENAME any more -- yet this test script continued to pass.  It turns
	out that this script doesn't actually check for FILENAME.

	This commit extends the test pattern to check for the full warning
	string, including FILENAME, and also removes some uses of '.*' to make
	the test stricter.

	Simplify decode_locdesc
	While looking into another bug, I noticed that the DWARF cooked
	indexer picks up an address for this symbol:

	 <1><82>: Abbrev Number: 2 (DW_TAG_variable)
	    <83>   DW_AT_specification: <0x9f>
	    <87>   DW_AT_location    : 10 byte block: e 0 0 0 0 0 0 0 0 e0 	(DW_OP_const8u: 0 0; DW_OP_GNU_push_tls_address or DW_OP_HP_unknown)
	    <92>   DW_AT_linkage_name: (indirect string, offset: 0x156): _ZN9container8tlsvar_0E

	This happens because decode_locdesc allows the use of
	DW_OP_GNU_push_tls_address.

	This didn't make sense to me.  I looked into it a bit more, and I
	think decode_locdesc is used in three ways:

	1. Find a constant address of a symbol that happens to be encoded as a
	   location expression.

	2. Find the offset of a function in a virtual table.  (This one should
	   probably be replaced by code to just evaluate the expression in
	   gnu-v3-abi.c -- but there's no point yet because no compiler
	   actually seems to emit correct DWARF here, see the bug linked in
	   the patch.)

	3. Find the offset of a field, if the offset is a constant.

	None of these require TLS.

	This patch simplifies decode_locdesc by removing any opcodes that
	don't fit into the above.  It also changes the API a little, to make
	it less difficult to use.

	Regression tested on x86-64 Fedora 36.

	Simplify auto_load_expand_dir_vars and remove substitute_path_component
	This simplifies auto_load_expand_dir_vars to first split the string,

	Then this patch also removes substitute_path_component, as it is no
	longer called.  This is nice because it helps with the long term goal
	of removing utils.h.

	GDB/MI commands does not take reference types into account, so that
	references to arbitrarily large structures are considered "simple" and
	printed. This means that the '--simple-values' argument cannot be used
	by IDEs when tracing the stack due to the time taken to print large
	structures passed by reference.

	DETAILS

	Various GDB/MI commands ('-stack-list-arguments', '-stack-list-locals',
	'-stack-list-variables' and so on) take a PRINT-VALUES argument which
	may be '--no-values' (0), '--all-values' (1) or '--simple-values' (2).
	In the '--simple-values' case, the command is supposed to print the
	name, type, and value of variables with simple types, and print only the
	name and type of variables with compound types.

	The '--simple-values' argument ought to be suitable for IDEs that need
	to update their user interface with the program's call stack every time
	the program stops. However, it does not take C++ reference types into
	account, and this makes the argument unsuitable for this purpose.

	For example, consider the following C++ program:

	    struct s {
	        int v[10];
	    };

	    int
	    sum(const struct s &s)
	    {
	        int total = 0;
	        for (int i = 0; i < 10; ++i) total += s.v[i];
	        return total;
	    }

	    int
	    main(void)
	    {
	        struct s s = { { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 } };
	        return sum(s);
	    }

	If we start GDB in MI mode and continue to 'sum', the behaviour of
	'-stack-list-arguments' is as follows:

	    (gdb)
	    -stack-list-arguments --simple-values
	    ^done,stack-args=[frame={level="0",args=[{name="s",type="const s &",value="@0x7fffffffe310: {v = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}}"}]},frame={level="1",args=[]}]

	Note that the value of the argument 's' was printed, even though 's' is
	a reference to a structure, which is not a simple value.

	See https://github.com/microsoft/MIEngine/pull/673 for a case where this
	behaviour caused Microsoft to avoid the use of '--simple-values' in
	their MIEngine debug adapter, because it caused Visual Studio Code to
	take too long to refresh the call stack in the user interface.

	SOLUTIONS

	There are two ways we could fix this problem, depending on whether we
	consider the current behaviour to be a bug.

	1. If the current behaviour is a bug, then we can update the behaviour
	   of '--simple-values' so that it takes reference types into account:
	   that is, a value is simple if it is neither an array, struct, or
	   union, nor a reference to an array, struct or union.

	   In this case we must add a feature to the '-list-features' command so
	   that IDEs can detect that it is safe to use the '--simple-values'
	   argument when refreshing the call stack.

	2. If the current behaviour is not a bug, then we can add a new option
	   for the PRINT-VALUES argument, for example, '--scalar-values' (3),
	   that would be suitable for use by IDEs.

	   In this case we must add a feature to the '-list-features' command
	   so that IDEs can detect that the '--scalar-values' argument is
	   available for use when refreshing the call stack.

	PATCH

	This patch implements solution (1) as I think the current behaviour of
	not printing structures, but printing references to structures, is
	contrary to reasonable expectation.

	[gdb/build] Fix frame_list position in frame.c
	In commit 995a34b1772 ("Guard against frame.c destructors running before
	frame-info.c's") the following problem was addressed.

	The frame_info_ptr destructor:
	...
	  ~frame_info_ptr ()
	  {
	    frame_list.erase (frame_list.iterator_to (*this));
	  }
	...
	uses frame_list, which is a static member of class frame_info_ptr,
	instantiated in frame-info.c:
	...
	intrusive_list<frame_info_ptr> frame_info_ptr::frame_list;
	...

	Then there's a static frame_info_pointer variable named selected_frame in
	frame.c:
	...
	static frame_info_ptr selected_frame;
	...

	Because the destructor of selected_frame uses frame_list, its destructor needs
	to be called before the destructor of frame_list.

	But because they're in different compilation units, the initialization order and
	consequently destruction order is not guarantueed.

	The commit fixed this by handling the case that the destructor of frame_list
	is called first, adding a check on is_linked ():
	...
	   ~frame_info_ptr ()
	   {
	-    frame_list.erase (frame_list.iterator_to (*this));
	+    /* If this node has static storage, it may be deleted after
	+       frame_list.  Attempting to erase ourselves would then trigger
	+       internal errors, so make sure we are still linked first.  */
	+    if (is_linked ())
	+      frame_list.erase (frame_list.iterator_to (*this));
	   }
	...

	However, since then frame_list has been moved into frame.c, and
	initialization/destruction order is guarantueed inside a compilation unit.

	Revert aforementioned commit, and fix the destruction order problem by moving
	frame_list before selected_frame.

	Reverting the commit is another way of fixing the already fixed
	Wdangling-pointer warning reported in PR build/30413, in a different way than
	commit 9b0ccb1ebae ("Pass const frame_info_ptr reference for
	skip_[language_]trampoline").

	Each new frame_info_ptr is being pushed on a static frame list and g++

	because it can inline enough code in this specific case).

	that as workaround for this warning.

	Generated docs and include files
	bfd/doc/chew.c extracts documentation from source code comments

	[gdb/tui] Fix TUI resizing for TERM=ansi
	With TERM=ansi, when resizing a TUI window from LINES/COLUMNS 31/118
	(maximized) to 20/78 (de-maximized), I get a garbled screen (that ^L doesn't
	fix) and a message:
	...
	@@ resize done 0, size = 77x20
	...
	with the resulting width being 77 instead of the expected 78.

	[ The discrepancy also manifests in CLI, filed as PR30346. ]

	The discrepancy comes from tui_resize_all, where we ask readline for the
	screen size:
	...
	   rl_get_screen_size (&screenheight, &screenwidth);
	...

	As it happens, when TERM is set to ansi, readline decides that the terminal
	cannot auto-wrap lines, and reserves one column to deal with that, and as a
	result reports back one less than the actual screen width:
	...
	$ echo $COLUMNS
	78
	$ TERM=xterm gdb -ex "show width" -ex q
	Number of characters gdb thinks are in a line is 78.
	$ TERM=ansi  gdb -ex "show width" -ex q
	Number of characters gdb thinks are in a line is 77.
	...

	In tui_resize_all, we need the actual screen width, and using a screenwidth of
	one less than the actual value garbles the screen.

	This is currently not causing trouble in testing because we have a workaround
	in place in proc Term::resize.  If we disable the workaround:
	...
	-       stty columns [expr {$_cols + 1}] < $::gdb_tty_name
	+       stty columns $_cols < $::gdb_tty_name
	...
	and dump the screen we get the same type of screen garbling:
	...
	    0 +---------------------------------------+|
	    1                                         ||
	    2                                         ||
	    3                                         ||
	...

	Another way to reproduce the problem is using command "maint info screen".
	After starting gdb with TERM=ansi, entering TUI, and issuing the command, we
	get:
	...
	Number of characters curses thinks are in a line is 78.
	...
	and after maximizing and demaximizing the window we get:
	...
	Number of characters curses thinks are in a line is 77.
	...
	If we use TERM=xterm, we do get the expected 78.

	Fix this by:
	- detecting when readline will report back less than the actual screen width,
	- accordingly setting a new variable readline_hidden_cols,
	- using readline_hidden_cols in tui_resize_all to fix the resize problem, and
	- removing the workaround in Term::resize.

	The test-case gdb.tui/empty.exp serves as regression test.

	I've applied the same fix in tui_async_resize_screen, the new test-case
	gdb.tui/resize-2.exp serves as a regression test for that change.  Without
	that fix, we have:
	...
	FAIL: gdb.tui/resize-2.exp: again: gdb width 80

	What we see here is that when using the MI a user can create
	thread-specific breakpoints for non-existent threads.  Then if we try
	to use the CLI 'info breakpoints' command GDB throws an assertion.
	The assert is a result of the print_thread_id call when trying to
	build the 'stop only in thread xx.yy' line; print_thread_id requires a
	valid thread_info pointer, which we can't have for a non-existent
	thread.

	In contrast, when using the CLI we see this behaviour:

	  $ gdb -q /tmp/hello.x
	  Reading symbols from /tmp/hello.x...
	  (gdb) break main thread 99
	  Unknown thread 99.
	  (gdb)

	The CLI doesn't allow a breakpoint to be created for a non-existent
	thread.  So the 'info breakpoints' command is always fine.

	Interestingly, the MI -break-info command doesn't crash, this is
	because the MI uses global thread-ids, and so never calls
	print_thread_id.  However, GDB does support using CLI and MI in
	parallel, so we need to solve this problem.

	One option would be to change the CLI behaviour to allow printing
	breakpoints for non-existent threads.  This would preserve the current
	MI behaviour.

	The other option is to pull the MI into line with the CLI and prevent
	breakpoints being created for non-existent threads.  This is good for
	consistency, but is a breaking change for the MI.

	In the end I figured that it was probably better to retain the
	consistent CLI behaviour, and just made the MI reject requests to
	place a breakpoint on a non-existent thread.  The only test we had
	that depended on the old behaviour was
	gdb.mi/mi-thread-specific-bp.exp, which was added by me in commit:

	  commit 2fd9a436c8d24eb0af85ccb3a2fbdf9a9c679a6c
	  Date:   Fri Feb 17 10:48:06 2023 +0000

	      gdb: don't duplicate 'thread' field in MI breakpoint output

	I certainly didn't intend for this test to rely on this feature of the
	MI, so I propose to update this test to only create breakpoints for
	threads that exist.

	Actually, I've added a new test that checks the MI rejects creating a
	breakpoint for a non-existent thread, and I've also extended the test
	to run with the separate MI/CLI UIs, and then tested 'info
	breakpoints' to ensure this command doesn't crash.

	I've extended the documentation of the `-p` flag to explain the
	constraints better.

	I have also added a NEWS entry just in case someone runs into this
	issue, at least then they'll know this change in behaviour was
	intentional.

	One thing that I did wonder about while writing this patch, is whether
	we should treat requests like this, on both the MI and CLI, as another
	form of pending breakpoint, something like:

	  (gdb) break foo thread 9
	  Thread 9 does not exist.
	  Make breakpoint pending on future thread creation? (y or [n]) y
	  Breakpoint 1 (foo thread 9) pending.
	  (gdb) info breakpoints
	  Num     Type           Disp Enb Address    What
	  1       breakpoint     keep y   <PENDING>  foo thread 9

	Don't know if folk think that would be a useful idea or not?  Either
	way, I think that would be a separate patch from this one.

	The previous commit fixed set/show args when used with

2023-04-28  Andrew Burgess  <aburgess@redhat.com>

	gdb: make set/show args work with $_gdb_setting_str
	I noticed that $_gdb_setting_str was not working with 'args', e.g.:

	  $ gdb -q --args /tmp/hello.x arg1 arg2 arg3
	  Reading symbols from /tmp/hello.x...
	  (gdb) show args
	  Argument list to give program being debugged when it is started is "arg1 arg2 arg3".
	  (gdb) print $_gdb_setting_str("args")
	  $1 = ""

	This is because the 'args' setting is implemented using a scratch
	variable ('inferior_args_scratch') which is updated when the user does
	'set args ...'.  There is then a function 'set_args_command' which is
	responsible for copying the scratch area into the current inferior.

	However, when the user sets the arguments via the command line the
	scratch variable is not updated, instead the arguments are pushed
	straight into the current inferior.

	There is a second problem, when the current inferior changes the
	scratch area is not updated, which means that the value returned will
	only ever reflect the last call to 'set args ...' regardless of which
	inferior is currently selected.

	Luckily, the fix is pretty easy, set/show variables have an
	alternative API which requires we provide some getter and setter
	functions.  With this done the scratch variable can be removed and the
	value returned will now always reflect the current inferior.

	While working on set/show args I also rewrote show_args_command to
	remove the use of deprecated_show_value_hack.

	In infcmd.c, in order to add command completion to some of the 'set'

	This is no longer necessary, we already return the relevant
	cmd_list_element object when the set/show command is created, and we
	can use that to set the command completion callback.

	I don't know if there's actually any tests for completion of these

	In this list, we only have entries for the beginning of each line.  This
	is because of the remote target's support for range stepping.  The
	record-full layer can only record instructions when the underlying
	process target reports a stop.  With range stepping, the remote target
	single-steps multiple instructions at a time, so the record-full target
	doesn't get to see and record them all.

	Fix this by making the record-full layer disable range-stepping
	before handing the resume request to the beneath layer, forcing the
	remote target to report stops for each instruction.

	Allow strings with printf/eval
	PR 13098 explains that if a user attempts to use a string with either
	`printf' (or `eval'), gdb returns an error (inferior not running):

	(gdb) printf "%s\n", "hello"
	evaluation of this expression requires the target program to be active

	However, the parser can certainly handle this case:

	(gdb) p "hello"
	$1 = "hello"

	This discrepancy occurs because printf_c_string does not handle
	this specific case.  The passed-in value that we are attempting to print
	as a string is TYPE_CODE_ARRAY but it's lval type is not_lval.

	printf_c_string will only attempt to print a string from the value's
	contents when !TYPE_CODE_PTR, lval is lval_internalvar, and the value's
	type is considered a string type:

	  if (value->type ()->code () != TYPE_CODE_PTR
	      && value->lval () == lval_internalvar
	      && c_is_string_type_p (value->type ()))
	    {
	      ...
	    }

	Otherwise, it attempts to read the value of the string from the target's
	memory (which is what actually generates the "evaluation of this ..."
	error message).

	      gdb/testsuite: change newline patterns used in gdb_test

	There were some regressions in gdb.trace/*.exp tests when run with the
	native-gdbserver board.  This commit fixes these regressions.

	All the problems are caused by unnecessary trailing newline characters
	included in the patterns passed to gdb_test.  After the above commit
	the testsuite is stricter when matching trailing newlines, and so the
	additional trailing newline characters are now causing the test to
	fail.  Fix by removing all the excess trailing newline characters.

	In some cases this cleanup means we should use gdb_test_no_output,
	I've done that where appropriate.  In a couple of other places I've
	made use of multi_line to better build the expected output pattern.

	Fix PR30358, performance with --sort-section
	since af31506c we only use the binary tree when section sorting is
	required.  While its unbalanced and hence can degrade to a linear list
	it should otherwise have been equivalent to the old code relying on
	insertion sort.  Unfortunately it was not.  The old code directly used
	lang_add_section to populate the sorted list, the new code first
	populates the tree and only then does lang_add_section on the sorted
	result.

	In the testcase we have very many linkonce section groups, and hence
	lang_add_section won't actually insert anything for most of them.  That
	limited the to-be-sorted list length previously.  The tree-sorting code
	OTOH first created a tree of all candidates sections, including those
	that wouldn't be inserted by lang_add_section, hence increasing the size
	of the sorting problem.  In the testcase the chain length went from
	about 1500 to 106000, and in the degenerated case (as in the testcase)
	that goes in quadratically.

	This splits out most of the early-out code from lang_add_section to its
	own function and uses the latter to avoid inserting into the tree.  This
	refactoring slightly changes the order of early-out tests (the ones
	based on section flags is now done last, and only in lang_add_section).
	The new function is not a pure predicate: it can give warnings and it
	might change output_section, like the old early-out code did.  I have
	also added a skip-warning case in the first discard case, whose
	non-existence seemed to have been an oversight.

		* ldlang.c (wont_add_section_p): Split out from ...

	gdb/doc: extend the documentation of the jump command
	This commit addresses PR gdb/7946.  While checking for bugs relating
	to the jump command I noticed a long standing bug that points out a
	deficiency with GDB's documentation of the jump command.

	The bug points out that 'jump 0x...' is not always the same as 'set
	$pc = 0x...' and then 'continue'.  Writing directly to the $pc
	register does not update any auxiliary state, e.g. $npc on SPARC,
	while using 'jump' does.

	It felt like this would be an easy issue to address by adding a
	paragraph to the docs, so I took a stab at writing something suitable.

	gdb/testsuite: special case '^' in gdb_test pattern
	In this commit I propose that we add special handling for the '^' when
	used at the start of a gdb_test pattern.  Consider this usage:

	  gdb_test "some_command" "^command output pattern"

	I think the intention here is pretty clear - run 'some_command', and
	the output from the command should be exactly 'command output
	pattern'.

	After the previous commit which tightened up how gdb_test matches the
	final newline and prompt we know that the only thing after the output
	pattern will be a single newline and prompt, and the leading '^'
	ensures that there's no output before 'command output pattern', so
	this will do what I want, right?

	... except it doesn't.  The command itself will also needs to be
	matched, so I should really write:

	  gdb_test "some_command" "^some_command\r\ncommand output pattern"

	which will do what I want, right?  Well, that's fine until I change
	the command and include some regexp character, then I have to write:

	  gdb_test "some_command" \
	    "^[string_to_regexp some_command]\r\ncommand output pattern"

	but this all gets a bit verbose, so in most cases I simply don't
	bother anchoring the output with a '^', and a quick scan of the
	testsuite would indicate that most other folk don't both either.

	What I propose is this: the *only* thing that can appear immediately
	after the '^' is the command converted into a regexp, so lets do that
	automatically, moving the work into gdb_test.  Thus, when I write:

	  gdb_test "some_command" "^command output pattern"

	Inside gdb_test we will spot the leading '^' in the pattern, and
	inject the regexp version of the command after the '^', followed by a
	'\r\n'.

	My hope is that given this new ability, folk will be more inclined to
	anchor their output patterns when this makes sense to do so.  This
	should increase our ability to catch any unexpected output from GDB
	that appears as a result of running a particular command.

	There is one problem case we need to consider, sometime people do
	this:

	  gdb_test "" "^expected output pattern"

	In this case no command is sent to GDB, but we are still expecting
	some output from GDB.  This might be a result of some asynchronous
	event for example.  As there is no command sent to GDB (from the
	gdb_test) there will be no command text to parse.

	In this case my proposed new feature injects the command regexp, which
	is the empty string (as the command itself is empty), but still
	injects the '\r\n' after the command regexp, thus we end up with this
	pattern:

	  ^\r\nexpected output pattern

	This extra '\r\n' is not what we should expected here, and so there is
	a special case inside gdb_test -- if the command is empty then don't
	add anything after the '^' character.

	There are a bunch of tests that do already use '^' followed by the
	command, and these can all be simplified in this commit.

	I've tried to run all the tests that I can to check this commit, but I
	am certain that there will be some tests that I manage to miss.
	Apologies for any regressions this commit causes, hopefully fixing the
	regressions will not be too hard.

	gdb/testsuite: change newline patterns used in gdb_test
	This commit makes two changes to how we match newline characters in
	the gdb_test proc.

	First, for the newline pattern between the command output and the
	prompt, I propose changing from '[\r\n]+' to an explicit '\r\n'.

	The old pattern would spot multiple newlines, and so there are a few
	places where, as part of this commit, I've needed to add an extra
	trailing '\r\n' to the pattern in the main test file, where GDB's
	output actually includes a blank line.

	But I think this is a good thing.  If a command produces a blank line
	then we should be checking for it, the current gdb_test doesn't do
	that.  But also, with the current gdb_test, if a blank line suddenly
	appears in the output, this is going to be silently ignored, and I
	think this is wrong, the test should fail in that case.

	Additionally, the existing pattern will happily match a partial
	newline.  There are a strangely large number of tests that end with a
	random '.' character.  Not matching a literal period, but matching any
	single character, this is then matching half of the trailing newline
	sequence, while the \[\r\n\]+ in gdb_test is matching the other half
	of the sequence.  I can think of no reason why this would be
	intentional, I suspect that the expected output at one time included a
	period, which has since been remove, but I haven't bothered to check
	on this.  In this commit I've removed all these unneeded trailing '.'
	characters.

	The basic rule of gdb_test after this is that the expected pattern
	needs to match everything up to, but not including the newline
	sequence immediately before the GDB prompt.  This is generally how the
	proc is used anyway, so in almost all cases, this commit represents no
	significant change.

	Second, while I was cleaning up newline matching in gdb_test, I've
	also removed the '[\r\n]*' that was added to the start of the pattern
	passed to gdb_test_multiple.

	The addition of this pattern adds no value.  If the user pattern
	matches at the start of a line then this would match against the
	newline sequence.  But, due to the '*', if the user pattern doesn't
	match at the start of a line then this group doesn't care, it'll
	happily match nothing.

	As such, there's no value to it, it just adds more complexity for no
	gain, so I'm removing it.  No tests will need updating as a
	consequence of this part of the patch.

	gdb/testsuite: use 'return' in gdb_test_no_output
	A TCL proc will return the return value of the last command executed
	within the proc's body if there is no explicit return call, so
	gdb_test_no_output is already returning the return value of
	gdb_test_multiple.

	However, I'm not a fan of (relying on) this implicit return value
	behaviour -- I prefer to be explicit about what we are doing.  So in
	this commit I have extended the comment on gdb_test_no_output to
	document the possible return values (just as gdb_test does), and
	explicitly call return.

	This should make no different to our testing, but I think it's clearer
	now what the gdb_test_no_output proc is expected to do.

	The two tests gdb.base/auxv.exp and gdb.base/list.exp both rely on the
	return value of gdb_test_no_output, and continue to pass after this
	change.

	I also spotted that gdb.base/watchpoint.exp could be updated to make
	use of gdb_test_no_output, so I did that.

	gdb: remove some trailing newlines from warning messages
	While working on a later patch in this series, which tightens up some
	of our pattern matching when using gdb_test, I ran into some failures
	caused by some warnings having a trailing newline character.

	The warning function already adds a trailing newline, and it is my
	understanding that we should not be adding a second by including a
	newline at the end of any warning message.

	The problem cases I found were in language.c and remote.c, in this
	patch I fix the cases I hit, but I also checked all the other warning
	calls in these two files and removed any additional trailing newlines
	I found.

	In remote.c the warning actually had a newline character in the middle
	of the warning message (in addition to the trailing newline), which
	I've removed.  I don't think it's helpful to forcibly split a warning
	as was done here -- in the middle of a sentence.  Additionally, the
	message isn't even that long (71 characters), so I think removing this
	newline is an improvement.

	None of the expected test result need updating with this commit,
	currently the patterns in gdb_test will match one or more newline
	sequences, so the tests are as happy with one newline (after this
	commit) as they are with two newlines (before this commit).  A later
	commit will change gdb_test so that it is not so forgiving, and these
	warnings would have caused some failures.

	gdb/testsuite: fix occasional failure in gdb.base/clear_non_user_bp.exp
	I noticed that the gdb.base/clear_non_user_bp.exp test would sometimes
	fail when run from a particular directory.

	The test tries to find the number of the first internal breakpoint
	using this proc:

	  proc get_first_maint_bp_num { } {
	      gdb_test_multiple "maint info break" "find first internal bp num" {
	  	-re -wrap "(-\[0-9\]).*" {
	  	    return $expect_out(1,string)
	  	}
	      }
	      return ""
	  }

	The problem is, at the time we issue 'maint info break' there are both
	internal breakpoint and non-internal (user created) breakpoints in
	place.  The user created breakpoints include the path to the source
	file.

	Sometimes, I'll be working from a directory that includes a number,
	like '/tmp/blah-1/gdb/etc', in which case the pattern above actually
	matches the '-1' from 'blah-1'.  In this case there's no significant
	problem as it turns out that -1 is the number of the first internal
	breakpoint.

	Sometimes my directory name might be '/tmp/blah-4/gdb/etc', in which
	case the above pattern patches '-4' from 'blah-4'.  It turns out this
	is also not a problem -- the test doesn't actually need the first
	internal breakpoint number, it just needs the number of any internal
	breakpoint.

	But sometimes my directory name might be '/tmp/blah-0/gdb/etc', in
	which case the pattern above matches '-0' from 'blah-0', and in this
	case the test fails - there is no internal breakpoint '-0'.

	Fix this by spotting that the internal breakpoint numbers always
	occurs after a '\r\n', and that they never start with a 0.  Our
	pattern becomes:

	  	-re -wrap "\r\n(-\[1-9\]\[0-9\]*).*" {
	  	    return $expect_out(1,string)
	  	}

	After this I'm no longer seeing any failures.

	    RISC-V: Support XVentanaCondOps extension
	    Ventana Micro has published the specification for their
	    XVentanaCondOps ("conditional ops") extension at
	      https://github.com/ventanamicro/ventana-custom-extensions/releases/download/v1.0.0/ventana-custom-extensions-v1.0.0.pdf
	    which contains two new instructions
	      - vt.maskc
	      - vt.maskcn
	    that can be used in constructing branchless sequences for
	    various conditional-arithmetic, conditional-logical, and
	    conditional-select operations.

	    To support such vendor-defined instructions in the mainline binutils,
	    this change also adds a riscv_supported_vendor_x_ext secondary
	    dispatch table (but also keeps the behaviour of allowing any unknow
	    X-extension to be specified in addition to the known ones from this
	    table).

	    As discussed, this change already includes the planned/agreed future
	    requirements for X-extensions (which are likely to be captured in the
	    riscv-toolchain-conventions repository):
	      - a public specification document is available (see above) and is
	        referenced from the gas-documentation
	      - the naming follows chapter 27 of the RISC-V ISA specification
	      - instructions are prefixed by a vendor-prefix (vt for Ventana)
	        to ensure that they neither conflict with future standard
	        extensions nor clash with other vendors

	    bfd/ChangeLog:

	            * elfxx-riscv.c (riscv_get_default_ext_version): Add riscv_supported_vendor_x_ext.
	            (riscv_multi_subset_supports): Recognize INSN_CLASS_XVENTANACONDOPS.

	gas: BPF pseudo-c syntax tests
	This patch expands the GAS BPF testsuite in order to also test the
	alternative pseudo-C syntax used in BPF assembly.

	This includes three main changes:

	- Some general GAS tests involving assignment and equality operands in
	  expressions (such as = and ==) are disabled in bpf-* targets,
	  because the syntax collides with the pseudo-C BPF assembly syntax.

	- New tests are added to the BPF GAS testsuite that test the pseudo-c
	syntax.  Tests for all BPF instructions are included.

	- New tests are added to the BPF GAS testsuite that test the support
	  for both syntaxes in the same source.

	gas: support for the BPF pseudo-c assembly syntax
	This patch adds support to the GNU assembler for an alternative
	assembly syntax used in BPF.  This syntax is C-like and very
	unconventional for an assembly language, but it is generated by
	clang/llvm and is also used in inline asm templates in kernel code, so
	we ought to support it.

	After this patch, the assembler is able to parse instructions in both
	supported syntax: the normal assembly-like syntax and the pseudo-C
	syntax.  Instruction formats can be mixed in the source program: the
	assembler recognizes the right syntax to use.

	[gdb/tui] Fix length of status line string
	In commit 5d10a2041eb ("gdb: add string_file::release method") this was added:
	...
	+  std::string string_val = string.release ();
	...
	without updating subsequent uses of string.size (), which returns 0 after the
	string.release () call.

	Fix this by:
	- using string_val.size () instead of string.size (), and
	- adding an assert that would have caught this regression.

	Tested on x86_64-linux.

	Rewrite gdb_mpz::operator==
	Simon pointed out that the recent changes to gdb_mpz caused a build
	failure on amd64 macOS.  It turns out to be somewhat difficult to
	overload a method in a way that will work "naturally" for all integer
	types; especially in a case like gdb_mpz::operator==, where it's
	desirable to special case all integer types that are no wider than
	'long'.

	After a false start, I came up with this patch, which seems to work.
	It applies the desirable GMP special cases directly in the body,
	rather than via overloads.

	i386-dis.c UB shift and other tidies
	1) i386-dis.c:12055:11: runtime error: left shift of negative value -1
	Bit twiddling is best done unsigned, due to UB on overflow of signed
	expressions.  Fix this by using bfd_vma rather than bfd_signed_vma
	everywhere in i386-dis.c except print_displacement.

	2) Return get32s and get16 value in a bfd_vma, reducing the need for
	temp variables.

	3) Introduce get16s and get8s functions to simplify the code.

	4) With some optimisation options gcc-13 legitimately complains about
	a fall-through in OP_I.  Fix that.  OP_I also doesn't need to use
	"mask" which was wrong for w_mode anyway.

	5) Masking with & 0xffffffff is better than casting to unsigned.  We
	don't know for sure that unsigned int is 32-bit.

	6) We also don't know that unsigned char is 8 bits.  Mask codep
	accesses everywhere.  I don't expect binutils will work on anything
	other than an 8-bit char host, but if we are masking codep accesses in
	some places we might as well be consistent.  (Better would be to use
	stdint.h types more in binutils.)

	binutils runtest $CC

	That doesn't work.  Those variables ought to be passed on the runtest

	After fixing that I had some fails due to binutils testprog.c now
	being compiled with the default "-g -O2" picked up in
	CFLAGS_FOR_TARGET.  Hack around that by passing -O0.

	Also, with the binutils testsuite now taking notice of CC_FOR_TARGET,

	happened to be built without --debug-id being enabled by default.

	section-select: Fix performance problem (PR30367)
	when using many wild-statements with non-wildcard filenames we
	were running into quadraticness via repeatedly using lookup_name
	on a long list of loaded files.  I've originally retained using
	lookup_name because that preserved existing behaviour most obviously.
	In particular in matching wild-statements when using a non-wildcard
	filename it matches against local_sym_name, not the filename member.
	If the wildspec would have an archive-spec or a wildcard it would use
	the filename member, though.  Also it would load the named file
	(and ignore it, as being not equal to the currently considered
	input-statement).

	Rewrite this to not use lookup_name but retain the comparison
	against local_sym_name with a comment to that effect.

	RISC-V: adjust logic to avoid register name symbols
	Special casing GPR names in my_getSmallExpression() leads to a number of
	inconsistencies. Generalize this by utilizing the md_parse_name() hook,
	limited to when instruction operands are being parsed (really: probed).
	Then both the GPR lookup there and the yet more ad hoc workaround for
	PR/gas 29940 can be removed (including its extension needed for making
	the compressed form JAL work again).

	RISC-V: test for expected / no unexpected symbols
	Both the temporary workaround for PR/gas 29940 and the existing special
	casing of GPRs in my_getSmallExpression() aren't really tested anywhere
	(i.e. with the workarounds remove testing would still succeed). Nor is
	there any test for uses of symbols with names matching GPRs, where such
	is permitted. Before altering how this is to be dealt with, install two
	testcases covering the expected behavior. (For now this includes only
	known affected insns; re-ordering of entries in riscv_opcodes[] could,
	however, yield more of them.)

	RISC-V: don't recognize bogus relocations
	With my_getSmallExpression() consistently and silently failing on
	relocation operators not fitting an insn, it is no longer necessary to
	hand it percent_op_itype[] "just in case" (i.e. to avoid errors when a
	subsequent parsing attempt for another operand combination might
	succeed). This also eliminates the latent problem of percent_op_itype[]
	and percent_op_stype[] growing a non-identical set of recognized
	relocation operators.

	RISC-V: avoid redundant and misleading/wrong error messages
	The use of a wrong (for the insn) relocation operator (or a future one
	which simply isn't recognized by older gas yet) doesn't render the (rest
	of the) expression "bad". Furthermore alongside the error from
	expression() in most cases the parser would emit another error then
	anyway. Suppress the call to my_getExpression() in such a case,
	arranging for a guaranteed subsequent error message by marking the
	expression "illegal".

	RISC-V: drop "percent_op" parameter from my_getOpcodeExpression()
	Both callers check for no relocations, so there's no point parsing for
	some. Have the function pass percent_op_null into
	my_getSmallExpression(). Note that there's no point passing
	percent_op_itype: Elsewhere, especially when processing compressed alias
	insns ahead of non-alias ones, this has the effect of avoiding "bad
	expression" errors when another parsing pass may follow (and succeed).
	Here, however, all alternative forms of an insn type will again start
	with the same O4 or O2, so avoiding errors earlier on doesn't really
	help. Plus constructs with a relocation specifier (as percent_op_itype
	would permit) can't be specified anyway, as the scrubber eats the
	whitespace between .insn's type and the O4 or O2 expression when that
	starts with % or ( - i.e. these will be seen as e.g. "i%lo(x)", and
	riscv_ip() looks only for whitespace when finding the end of a mnemonic.

	RISC-V: minor effort reduction in relocation specifier parsing
	The sole caller of parse_relocation() has already checked for the %
	prefix, so there's no need to check for it again in the strncasecmp()
	and there's also no reason to make the involved string literals longer
	than necessary.

	[gdb/testsuite] Add debug prints in Term::wait_for
	The semantics of wait_for are non-trivial, and a bit hard to understand
	sometimes.

	Add some debug prints in wait_for that make it clear:
	- what regexps we're trying to match,
	- what strings we compare to the regexps, and
	- whether there's a match or mismatch.

	I've added this ad-hoc a couple of times, and it seems that it's worth having
	readily available.

	The debug prints are enabled by adding DEBUG_TUI_MATCHING=1 to the
	RUNTESTFLAGS:
	...
	$ make check RUNTESTFLAGS="gdb.tui/empty.exp DEBUG_TUI_MATCHING=1"

	[gdb/testsuite] Add warning for timeout in accept_gdb_output
	In accept_gdb_output we have:
	...
	            timeout {
	                # Assume a timeout means we somehow missed the
	                # expected result, and carry on.
	                return 0
	            }
	...

	The timeout is silent, and though in some places the return value is checked,
	this is not done consistently, and consequently there are silent timeouts
	when running the TUI testsuite (gdb.tui/*.exp and gdb.python/tui*.exp).

	Each timeout is 10 seconds, and there are 5 in total in the TUI tests, taking
	50 seconds overall:
	...
	real    1m0.275s
	user    0m10.440s
	sys     0m1.343s
	...

	With an entire testsuite run taking about 30 minutes, that is about 2.5% of
	the time spent waiting in TUI tests.

	Let's make the timeouts visible using a warning, such that they can be fixed.

	x86: work around compiler diagnosing dangling pointer
	For quite come time print_insn() has been storing the address of a local
	variable into info->private_data. Since the compiler can't know that the
	field won't be accessed again after print_insn() returns, it may kind of
	legitimately diagnose this. And recent enough gcc does as of the
	introduction of the fetch_error() return paths (replacing setjmp()-based
	error handling).

	Utilizing that neither prefix_name() nor i386_dis_printf() actually use
	info->private_data, zap the pointer in fetch_error(), after having
	retrieved it for local use.

	gdb: remove language_auto
	I think that the language_auto enumerator and the auto_language class
	can be removed.  There isn't really an "auto" language, it's only a
	construct of the "set language" command to say "pick the appropriate
	language automatically".  But "auto" is never the current language.  The
	`current_language` points to the current effective language, and the
	fact that we're in "auto language" mode is noted by the language_mode
	global.

	 - Change set_language to handle the "auto" (and "local", which is a
	   synonym) early, instead of in the for loop.  I think it makes the two
	   cases (auto vs explicit language) more clearly separated anyway.

	 - Adjust add_set_language_command to hard-code the "auto" string,
	   instead of using the "auto" language definition.

	 - Remove auto_language, rename auto_or_unknown_language to
	   unknown_language and move the bits of the existing unknown_language
	   in there.

	 - Remove the set_language at the end of _initialize_language.  I think
	   it's not needed, because we call set_language in gdb_init, after all
	   _initialize functions are called.  There is some chance that an
	   _initialize function that runs after _initialize_language implicitly
	   depends on current_language being set, but my testsuite runs haven't
	   found anything like that.

	 - Use language_unknown instead of language_auto when creating a minimal
	   symbol (minimal_symbol_reader::record_full).  I think that this value
	   is used to indicate that we don't know the symbol of the minimal
	   symbol (yet), so language_unknown makes sense to me.  Update a
	   condition accordingly in ada-lang.c.  symbol_find_demangled_name also
	   appears to "normalize" this value from "unknown" to "auto", remove
	   that part and update the condition to just check for
	   language_unknown.

	[gdb/testsuite] Add make-check-all.sh
	Directory gdb/testsuite/boards contains a number of host/target boards, which
	run a test-case (or test-cases) in a different way.

	The benefits of using these boards are:
	- improving test coverage of gdb,
	- making the testsuite more robust, and
	- making sure the test-cases work for non-native and remote setups, if
	  possible.

	Each board is slightly different, and developers need to learn how to use each
	one, what parameters to pass and how, and which ones can be used in
	combination with each other.  This is a threshold to start using them.

	And then there quite a few, so I suppose typically only a few will be used by
	each developer.

	Add script gdb/testsuite/make-check-all.sh, that's intended to function as a
	drop-in replacement of make check, while excercising all host/target boards in
	gdb/testsuite/boards.

	An example of make-check-all.sh for one test-case is:
	...
	 $  ~/gdb/src/gdb/testsuite/make-check-all.sh gdb.base/advance.exp
	 LOCAL:
	 # of expected passes            8

	While working on PRs tui/30337 and cli/30346 I came across various notions of
	width in gdb, as reported by gdb, readline, curses and the environment
	variables.

	As for gdb, readline and the environment variables, the way things work
	is:
	- Gdb asks readline to detect screen size,
	- readline sets the actual screen size in the environment variables
	  COLUMNS and LINES,
	- readline reports back a screen size to gdb, which may have one column
	  less than the actual screen size, to deal with lack of auto-wrap.
	  This becomes gdb's notion of screen size (in other words the point where
	  we can expect the gdb command line to wrap),
	- Gdb then explicitly sets readline's screen size, which readline itself may
	  adjust to deal with lack of auto-wrap.  This becomes readlines notion
	  of screen size (well, internally the unadjusted one, but it'll report back
	  the adjusted one).

	Add a command "maint info screen" that prints these notions, both for width
	and height.

	For TERM=xterm we have:
	...
	$ TERM=xterm gdb -ex "maint info screen"
	Number of characters gdb thinks are in a line is 118.
	Number of characters readline reports are in a line is 118.
	Number of characters curses thinks are in a line is 118.
	Number of characters environment thinks are in a line is 118 (COLUMNS).
	Number of lines gdb thinks are in a page is 27.
	Number of lines readline reports are in a page is 27.
	Number of lines curses thinks are in a page is 27.
	Number of lines environment thinks are in a page is 27 (LINES).
	...

	And for TERM=ansi:
	...
	$ TERM=ansi gdb -ex "maint info screen"
	Number of characters gdb thinks are in a line is 117.
	Number of characters readline reports are in a line is 116.
	Number of characters curses thinks are in a line is 118.
	Number of characters environment thinks are in a line is 118 (COLUMNS).
	Number of lines gdb thinks are in a page is 27.
	Number of lines readline reports are in a page is 27.
	Number of lines curses thinks are in a page is 27.
	Number of lines environment thinks are in a page is 27 (LINES).
	...

	[ The fact that we have "characters readline reports are in a line is 116" is
	is due to gdb making readline adjust twice for the lack of auto-wrap, this is
	PR cli/30346.

	Likewise we can detect tui/30337 by doing a resize in TUI mode and doing
	"maint info screen":
	...
	Number of characters characters curses thinks are in a line is 110.
	Number of characters environment thinks are in a line is 111 (COLUMNS). ]

	And for TERM=ansi, with width and heigth set to 0:
	...
	Number of characters gdb thinks are in a line is 4294967295 (unlimited).
	Number of characters readline reports are in a line is 32766 (unlimited - 1).
	Number of characters curses thinks are in a line is 118.
	Number of characters environment thinks are in a line is 118 (COLUMNS).
	Number of lines gdb thinks are in a page is 4294967295 (unlimited).
	Number of lines readline reports are in a page is 32767 (unlimited).
	Number of lines curses thinks are in a page is 27.
	Number of lines environment thinks are in a page is 27 (LINES).
	...

	[ Note that when doing a resize by say maximizing or de-maximizing a terminal,
	all reported values are updated, except for curses when not in TUI mode.

	Maybe that means there's a bug.  If not, then maybe we should not print
	the curses lines unless in TUI mode, or annotate those lines such that it's
	clear that the values may be not up-to-date. ]

	I'd like to use this command in the regression test for PR cli/30346.

	Tested on x86_64-linux.

	Use entry values for 32-bit PPC struct return
	AdaCore has a local patch for PPC "finish", but last year, Ulrich
	Weigand pointed out that this patch was incorrect.  It may work for
	simple functions like the one in the internal test, but nothing
	guarantees that r3 will be preserved by the callee, so checking r3 on
	exit is not always correct.

	This patch fixes the problem using the same approach as PPC64: use the
	entry value of r3, if available.  Ulrich confirmed this matches the
	PPC32 ABI.

2023-04-21  Tom Tromey  <tromey@adacore.com>

	Handle erroneous DW_AT_call_return_pc
	On PPC64, with the test case included in an earlier patch, we found
	that "finish" would still not correctly find the return value via
	entry values.

	The issue is simple.  The compiler emits:

	   0x00000000100032b8 <+28>:	bl      0x1000320c <pck__create_large>
	   0x00000000100032bc <+32>:	nop
	   0x00000000100032c0 <+36>:	li      r9,42

	... but the DWARF says:

	    <162a>   DW_AT_call_return_pc: 0x100032c0

	That is, the declared return PC is one instruction past the actual
	return PC.

	This patch adds a new arch hook to handle this scenario, and
	implements it for PPC64.  Some care is taken so that GDB will continue
	to work if this compiler bug is fixed.  A GCC patch is here:

	    https://gcc.gnu.org/pipermail/gcc-patches/2023-March/613336.html

	No check for 'nop' is done, as subsequent discussion revealed that the
	linker might replace this with another instruction.

	Handle function descriptors in call_site_target
	call_site_target::iterate_over_addresses may look up a minimal symbol.
	On platforms like PPC64 that use function descriptors, this may find
	an unexpected address.  The fix is to use gdbarch_convert_from_func_ptr_addr
	to convert from a function descriptor to the address recorded at the
	call site.

	I've added a new test case that is based on the internal AdaCore test
	that provoked this bug.  However, I'm unable to test it as-is on
	PPC64.

	x86: drop (explicit) BFD64 dependency from disassembler
	get64() is unreachable when !BFD64 (due to a check relatively early in

	x86: change fetch error handling for get<N>()
	Make them return boolean and convert FETCH_DATA() uses to fetch_code().
	With this no further users of FETCH_DATA() remain, so the macro and its
	backing function are dropped as well.

	Leave value types as they were for the helper functions, even if I don't
	think that beyond get64() use of bfd_{,signed_}vma is really necessary.
	With type change of "disp" in OP_E_memory(), change the 2nd parameter of
	print_displacement() to a signed type as well, though (eliminating the
	need for a local variable of signed type). This also eliminates the need
	for custom printing of '-' in Intel syntax displacement expressions.

	RISC-V: Optimize relaxation of gp with max_alignment.
	This should be the first related issue, which posted in riscv-gnu-toolchain,
	https://github.com/riscv-collab/riscv-gnu-toolchain/issues/497

	If the output sections are not between gp and the symbol, then their alignments
	shouldn't affect the gp relaxation.  However, this patch improves this idea
	even more, it limits the range to the gp+-2k, which means only the output
	section which are in the [gp-2K, gp+2K) range need to be considered.

	Even if the output section candidates may be different for each relax passes,
	the symbol that can be relaxed ar this round will not be truncated at next
	round.  That is because this round you can do relaxation which means that the
	section where the symbol is located is within the [gp-2K, gp+2K) range, so all
	the output section alignments between them should be considered.  In other
	words, if the alignments between them may cause truncated, then we should
	already preserve the size and won't do the gp relaxation this time.

	This patch can resolve the github issue which mentioned above, and also passed
	all gcc/binutils regressions of riscv-gnu-toolchain, so should be worth and
	safe enough to commit.

	Originally, this patch also do the same optimization for the call relaxations,
	https://sourceware.org/pipermail/binutils/2022-October/123918.html
	But just in case there is something that has not been considered, we only
	deal with the gp relaxation at this time.

	bfd/
		* elfnn-riscv.c (riscv_elf_link_hash_table): Added new bfd_vma,
		max_alignment_for_gp.  It is used to record the maximum alignment of
		the output sections, which are in the [gp-2K, gp+2k) range.
		(riscv_elf_link_hash_table_create): Init max_alignment_for_gp to -1.
		(_bfd_riscv_get_max_alignment): Added new parameter, gp.  If gp is
		zero, then all the output section alignments are possible candidates;
		Otherwise, only the output sections which are in the [gp-2K, gp+2K)

	Keeping track of rs6000-coff archive element pointers
	rs6000-coff archives use a linked list of file offsets, where each
	element points to the next element.  The idea is to allow updating of
	large archives quickly without rewriting the whole archive.  (binutils
	ar does not do this.)  Unfortunately this is an easy target for
	fuzzers to create an archive that will cause ar or any other tool
	processing archives to hang.  I'd implemented guards against pointing
	back to the previous element, but of course that didn't last long.

	So this patch implements a scheme to keep track of file offset ranges
	used by elements as _bfd_read_ar_hdr is called for each element.  See
	the add_range function comment.  I needed a place to stash the list,
	so chose the obvious artdata.tdata backend extension to archive's
	tdata, already used by xcoff.  That involved a little cleanup, because
	while it would be possible to continue using different artdata.tdata
	for the big and small archives, it's nicer to use a union.

	If anyone is concerned this list of element ranges might grow large
	and thus significantly slow down the tools, adjacent ranges are
	merged.  In fact something like "ar t" will only ever have one range
	on xcoff archives generated by binutils/ar.  I agree there might still
	be a problem with ld random element access via the armap.

	x86: parse_register() must not alter the parsed string
	This reverts the code change done by 100f993c53a5 ("x86: Check

	place, no matter that it's at best marginally useful in that shape.)

	The problem instead is that parse_register() alters the string handed to

	the function's behavior is a result of get_symbol_name()'s, make a copy
	of the incoming string before invoking that function.

	Like for parse_real_register() follow the model of strtol() et al: input
	string is const-qualified to signal that the string isn't altered, but
	the returned "end" pointer is not const-qualified, requiring const to be
	cast away (which generally is a bad idea, but the alternative would

	PowerPC: fix _Float128 type output string
	PowerPC supports two 128-bit floating point formats, the IBM long double
	and IEEE 128-bit float.  The issue is the DWARF information does not
	distinguish between the two.  There have been proposals of how to extend
	the DWARF information as discussed in

	https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104194

	but has not been fully implemented.

	GCC introduced the _Float128 internal type as a work around for the issue.
	The workaround is not transparent to GDB.  The internal _Float128 type
	name is printed rather then the user specified long double type.  This
	patch adds a new gdbarch method to allow PowerPC to detect the GCC
	workaround.  The workaround checks for "_Float128" name when reading the
	base typedef from the die_info.  If the workaround is detected, the type
	and format fields from the _Float128 typedef are copied to the long
	double typedef.  The same is done for the complex long double typedef.

	This patch fixes 74 regression test failures in
	gdb.base/whatis-ptype-typedefs.exp on PowerPC with IEEE float 128 as the
	default on GCC.  It fixes one regression test failure in
	gdb.base/complex-parts.exp.

	The patch has been tested on Power 10 where GCC defaults to IEEE Float

	RISC-V: Cache the latest mapping symbol and its boundary.
	This issue was reported from https://github.com/riscv-collab/riscv-gnu-toolchain/issues/1188

	Current flow:
	1) Scan any mapping symbol less than this instruciton.
	2) If not found, did a backward search.

	The flow seems not big issue, let run an example here:

	$x:
	0x0 a   <--- Found at step 1
	0x4 b   <--- Not found in step 1, but found at step 2
	0x8 c   <--- Not found in step 1, but found at step 2
	$d
	0x12 .word 1234 <-- Found at step 1

	The instruciton didn't have the same address with mapping symbol will
	still did backward search again and again.

	So the new flow is:
	1) Use the last mapping symbol status if the address is still within the range
	   of the current mapping symbol.
	2) Scan any mapping symbol less than this instruciton.
	3) If not found, did a backward search.
	4) If a proper mapping symbol is found in either step 2 or 3, find its boundary,
	   and cache that.

	Use the same example to run the new flow again:

	$x:
	0x0 a   <--- Found at step 2, the boundary is 0x12
	0x4 b   <--- Cache hit at step 1, within the boundary.
	0x8 c   <--- Cache hit at step 1, within the boundary.
	$d
	0x12 .word 1234 <-- Found at step 2, the boundary is the end of section.

	The disassemble time of the test cases has been reduced from ~20 minutes to ~4
	seconds.

	Our library does not set the default version for symbols.
	This is correct because we don't know which libC will be used.

	gcc and g++ links differently the version symbols when the default version is

	our pthread_create@GLIBC_2.0 by default.

	The current implementation of the interposed functions is:
	  If we are in our pthread_create@GLIBC_<NN>,
	  we use dlvsym (dlflag, "pthread_create", "GLIBC_<NN>") to find and call
	  the same function from libC.
	In the test from PR 30360, pthread_create@GLIBC_2.0 is not in the current libC.

	gdb/amdgpu: add follow fork and exec support
	Prior to this patch, it's not possible for GDB to debug GPU code in fork
	children or after an exec.  The amd-dbgapi target attaches to processes
	when an inferior appears due to a "run" or "attach" command, but not
	after a fork or exec.  This patch adds support for that, such that it's
	possible to for an inferior to fork and for GDB to debug the GPU code in
	the child.

	To achieve that, use the inferior_forked and inferior_execd observers.

	In the case of fork, we have nothing to do if `child_inf` is nullptr,
	meaning that GDB won't debug the child.  We also don't attach if the
	inferior has vforked.  We are already attached to the parent's address
	space, which is shared with the child, so trying to attach would cause
	problems.  And anyway, the inferior can't do anything other than exec or
	exit, it certainly won't start GPU kernels before exec'ing.

	In the case of exec, we detach from the exec'ing inferior and attach to
	the following inferior.  This works regardless of whether they are the
	same or not.  If they are the same, meaning the execution continues in
	the existing inferior, we need to do a detach/attach anyway, as
	amd-dbgapi needs to be aware of the new address space created by the
	exec.

	Note that we use observers and not target_ops::follow_{fork,exec} here.
	When the amd-dbgapi target is compiled in, it will attach (in the
	amd_dbgapi_process_attach sense, not the ptrace sense) to native
	inferiors when they appear, but won't push itself on the inferior's
	target stack just yet.  It only pushes itself if the inferior
	initializes the ROCm runtime.  So, if a non-GPU-using inferior calls
	fork, an amd_dbgapi_target::follow_fork method would not get called.
	Same for exec.  A previous version of the code had the amd-dbgapi target
	pushed all the time, in which case we could use the target methods.  But
	we prefer having the target pushed only when necessary, it's less
	intrusive when doing native debugging that doesn't involve the GPU.

	gdb: switch to right inferior in fetch_inferior_event
	The problem explained and fixed in the previous patch could have also
	been fixed by this patch.  But I think it's good change anyhow, that
	could prevent future bugs, so here it is.

	fetch_inferior_event switches to an arbitrary (in practice, the first) inferior
	of the process target of the inferior used to fetch the event.  The idea is
	that the event handling code will need to do some target calls, so we want to
	switch to an inferior that has target target.

	However, you can have two inferiors that share a process target, but with one
	inferior having an additional target on top:

	        inf 1            inf 2
	        -----            -----
	                         another target
	        process target   process target
	        exec             exec

	Let's say inferior 2 is selected by do_target_wait and returns an event that is
	really synthetized by "another target".  This "another target" could be a
	thread or record stratum target (in the case explained by the previous patch,
	it was the arch stratum target, but it's because the amd-dbgapi abuses the arch
	layer).  fetch_inferior_event will then switch to the first inferior with
	"process target", so inferior 1.  handle_signal_stop then tries to fetch the
	thread's registers:

	    ecs->event_thread->set_stop_pc
	      (regcache_read_pc (get_thread_regcache (ecs->event_thread)));

	This will try to get the thread's register by calling into the current target
	stack, the stack of inferior 1.  This is problematic because "another target"
	might have a special fetch_registers implementation.

	I think it would be a good idea to switch to the inferior for which the
	even was reported, not just some inferior of the same process target.
	This will ensure that any target call done before we eventually call
	context_switch will be done on the full target stack that reported the
	event.

	Not all events are associated to an inferior though.  For instance,
	TARGET_WAITKIND_NO_RESUMED.  In those cases, some targets return
	null_ptid, some return minus_one_ptid (ideally the expected return value
	should be clearly defined / documented).  So, if the ptid returned is
	either of these, switch to an arbitrary inferior with that process
	target, as before.

	gdb: make regcache::raw_update switch to right inferior
	With the following patch, which teaches the amd-dbgapi target to handle
	inferiors that fork, we end up with target stacks in the following
	state, when an inferior that does not use the GPU forks an inferior that
	eventually uses the GPU.

	    inf 1            inf 2
	    -----            -----
	                     amd-dbgapi
	    linux-nat        linux-nat
	    exec             exec

	When a GPU thread from inferior 2 hits a breakpoint, the following
	sequence of events would happen, if it was not for the current patch.

	 - we start with inferior 1 as current
	 - do_target_wait_1 makes inferior 2 current, does a target_wait, which
	   returns a stop event for an amd-dbgapi wave (thread).
	 - do_target_wait's scoped_restore_current_thread restores inferior 1 as
	   current
	 - fetch_inferior_event calls switch_to_target_no_thread with linux-nat
	   as the process target, since linux-nat is officially the process
	   target of inferior 2.  This makes inferior 1 the current inferior, as
	   it's the first inferior with that target.
	 - In handle_signal_stop, we have:

	    ecs->event_thread->suspend.stop_pc
	      = regcache_read_pc (get_thread_regcache (ecs->event_thread));

	    context_switch (ecs);

	   regcache_read_pc executes while inferior 1 is still the current one
	   (because it's before the `context_switch`).  This is a problem,
	   because the regcache is for a ptid managed by the amd-dbgapi target
	   (e.g. (12345, 1, 1)), a ptid that does not make sense for the
	   linux-nat target.  The fetch_registers target call goes directly
	   to the linux-nat target, which gets confused.
	 - We would then get an error like:

	     Couldn't get extended state status: No such process.

	   ... since linux-nat tries to do a ptrace call on tid 1.

	GDB should switch to the inferior the ptid belongs to before doing the
	target call to fetch registers, to make sure the call hits the right
	target stack (it should be handled by the amd-dbgapi target in this
	case).  In fact the following patch does this change, and it would be
	enough to fix this specific problem.

	However, I propose to change regcache to make it switch to the right
	inferior, if needed, before doing target calls.  That makes the
	interface as a whole more independent of the global context.

	My first attempt at doing this was to find an inferior using the process
	stratum target and the ptid that regcache already knows about:

	      gdb::optional<scoped_restore_current_thread> restore_thread;
	      inferior *inf = find_inferior_ptid (this->target (), this->ptid ());
	      if (inf != current_inferior ())
		{
		  restore_thread.emplace ();
		  switch_to_inferior_no_thread (inf);
		}

	However, this caused some failures in fork-related tests and gdbserver
	boards.  When we detach a fork child, we may create a regcache for the
	child, but there is no corresponding inferior.  For instance, to restore
	the PC after a displaced step over the fork syscall.  So
	find_inferior_ptid would return nullptr, and
	switch_to_inferior_no_thread would hit a failed assertion.

	So, this patch adds to regcache the information "the inferior to switch
	to to makes target calls".  In typical cases, it will be the inferior
	that matches the regcache's ptid.  But in some cases, like the detached
	fork child one, it will be another inferior (in this example, it will be
	the fork parent inferior).

	The problem that we witnessed was in regcache::raw_update specifically,
	but I looked for other regcache methods doing target calls, and added
	the same inferior switching code to raw_write too.

	In the regcache constructor and in get_thread_arch_aspace_regcache,
	"inf_for_target_calls" replaces the process_stratum_target parameter.
	We suppose that the process stratum target that would be passed
	otherwise is the same that is in inf_for_target_calls's target stack, so
	we don't need to pass both in parallel.  The process stratum target is
	still used as a key in the `target_pid_ptid_regcache_map` map, but
	that's it.

	There is one spot that needs to be updated outside of the regcache code,
	which is the path that handles the "restore PC after a displaced step in
	a fork child we're about to detach" case mentioned above.

	regcache_test_data needs to be changed to include full-fledged mock
	contexts (because there now needs to be inferiors, not just targets).

	gdb: add inferior_forked observable
	In the upcoming patch to support fork in the amd-dbgapi target, the
	amd-dbgapi target will need to be notified of fork events through an
	observer, to attach itself (attach in the amd-dbgapi sense, not ptrace
	sense) to the new inferior / process.

	The reason that this can't be done through target_ops::follow_fork is
	that the amd-dbgapi target isn't pushed on the inferior's target stack
	right away.  It attaches itself to the process and only pushes itself on
	its target stack if and when the inferior initializes the ROCm runtime.

	If an inferior that is not using the ROCm runtime forks, we want to be
	notified of it, so we can attach to the child, and catch if the child
	starts using the ROCm runtime.

	So, add a new observable and notify it in follow_fork_inferior.  It will
	be used later in this series.

	      [gdb/testsuite] Fix unbalanced quotes in mi_expect_stop argument

	Introduced the use of {"} in mi-support.exp.  There is absolutely
	nothing wrong with this in any way.  However, this is causing my
	editor to get the syntax highlighting of this file wrong after this
	point.

	Maybe the real answer is to use a better editor, or fix my current
	editor.... but I'm hoping I can instead take the lazy approach of just
	changing {"} to "\"", which is handled fine, and means exactly the
	same as far as I understand it.

	There should be no change in what is tested after this commit.

	pauth: Create new feature string for pauth to prevent crashing older gdb's
	Older gdb's (9, 10, 11 and 12) have a bug that causes them to crash whenever
	a target reports the pauth feature string in the target description and also
	provide additional register outside of gdb's known and expected feature
	strings.

	This was fixed in gdb 13 onwards, but that means we're stuck with gdb's out
	there that will crash on connection to the above targets.

	QEMU has postponed inclusion of the pauth feature string in version 8, and
	instead we agreed to use a new feature name to prevent crashing those older
	gdb's.

	Initially there was a plan to backport a trivial fix all the way to gdb 9, but
	given QEMU's choice, this is no longer needed.

	This new feature string is org.gnu.gdb.aarch64.pauth_v2, and should be used
	by all targets going forward, except native linux gdb and gdbserver, for
	backwards compatibility with older gdb's/gdbserver's.

	gdb/gdbserver will still emit the old feature string for Linux since it doesn't
	report additional system registers and thus doesn't cause a crash of older
	gdb's. We can revisit this in the future once the problematic gdb's are likely
	no longer in use.

	I've added some documentation to explain the situation.

	debug registers: Add missing debug version entry for FEAT_Debugv8p8
	The Arm Architecture Reference Manual defines debug version 0b1010 for
	FEAT_Debugv8p8. This is used to identify valid hardware debug registers.

	gdb currently only knows about versions up to FEAT_Debugv8p4. This patch
	teaches gdb about this new version.

	No visible changes should happen as consequence of this patch, but in the
	future gdb will be able to identify debug registers in newer hardware.

	Regression-tested on aarch64-linux Ubuntu 20.04/22.04.

	gdb/testsuite: Skip dump ihex for 64-bit address in gdb.base/dump.exp
	(1) Description of problem

	In the current code, when execute the following test on LoongArch:

	$make check-gdb TESTS="gdb.base/dump.exp"
	```
	FAIL: gdb.base/dump.exp: dump array as value, intel hex
	FAIL: gdb.base/dump.exp: dump struct as value, intel hex
	FAIL: gdb.base/dump.exp: dump array as memory, ihex
	FAIL: gdb.base/dump.exp: dump struct as memory, ihex

	```
	These tests passed on the X86_64,

	(2) Root cause

	On LoongArch, variable intarray address 0x120008068 out of range for IHEX,
	so dump ihex test failed.

	gdb.base/dump.exp has the following code to check 64-bit address

	```
	 # Check the address of a variable.  If it is bigger than 32-bit,
	 # assume our target has 64-bit addresses that are not supported by SREC,
	 # IHEX and TEKHEX.  We skip those tests then.
	 set max_32bit_address "0xffffffff"
	 set data_address [get_hexadecimal_valueof "&intarray" 0x100000000]
	 if {${data_address} > ${max_32bit_address}} {
	    set is64bitonly "yes"
	}
	```

	We check the "&intarray" on different target as follow:

	```
	$gdb gdb/testsuite/outputs/gdb.base/dump/dump
	...
	(gdb) start
	...

	On X86_64:
	(gdb) print /x &intarray
	$1 = 0x404060

	On LoongArch:
	(gdb) print /x &intarray
	$1 = 0x120008068
	```
	The variable address difference here is due to the link script
	of linker.

	```
	On X86_64:
	$ld --verbose
	...
	PROVIDE (__executable_start = SEGMENT_START("text-segment", 0x400000));
	. = SEGMENT_START("text-segment", 0x400000) + SIZEOF_HEADERS;

	On LoongArch:
	$ld --verbose
	...
	PROVIDE (__executable_start = SEGMENT_START("text-segment", 0x120000000));
	. = SEGMENT_START("text-segment", 0x120000000) + SIZEOF_HEADERS;

	```

	(3) How to fix

	Because 64-bit variable address out of range for IHEX, it's not an
	functional problem for LoongArch. Refer to the handling of 64-bit
	targets in this testsuite, use the "is64bitonly" flag to skip those
	tests for the target has 64-bit addresses.

	Avoid double-free with debuginfod
	PR gdb/29257 points out a possible double free when debuginfod is in

	seems to assume that symfile_bfd_open will return NULL on error,
	whereas in reality it throws an exception.  As this code isn't

	Re: pe_ILF_object_p and bfd_check_format_matches
	The last patch wasn't quite correct.  bfd_preserve_restore also needs
	to handle an in-memory to file backed transition, seen in a testcase
	ILF object matching both pei-arm-little and pei-arm-wince-little.
	There the first match is saved in preserve_match, and restored at the
	end of the bfd_check_format_matches loop making the bfd in-memory.  On
	finding more than one match the function wants to restore the bfd back
	to its original state with another bfd_preserve_restore call before
	exiting with a bfd_error_file_ambiguously_recognized error.

	It is also not correct to restore abfd->iostream unless the iovec
	changes.  abfd->iostream is a FILE* when using cache_iovec, and if
	the file has been closed and reopened the iostream may have changed.

		* format.c (io_reinit): New function.

	[gdb/tui] Fix left margin in disassembly window
	With a hello world a.out, and maint set tui-left-margin-verbose on, we have
	this disassembly window:
	...
	┌───────────────────────────────────────────────────────────┐
	│___ 0x555555555149 <main>           endbr64                │
	│___ 0x55555555514d <main+4>         push   %rbp            │
	│___ 0x55555555514e <main+5>         mov    %rsp,%rbp       │
	│B+> 0x555555555151 <main+8>         lea    0xeac(%rip),%rax│
	│___ 0x555555555158 <main+15>        mov    %rax,%rdi       │
	...
	Note the space between "B+>" and 0x555555555151.  The space shows that a bit
	of the left margin is not written, which is a problem because that location is
	showing a character previously written, which happens to be a space, but also
	may be something else, for instance a '[' as reported in PR tui/30325.

	The problem is caused by confusion about the meaning of:
	...
	 #define TUI_EXECINFO_SIZE 4
	...

	There's the meaning of defining the size of this zero-terminated char array:
	...
	      char element[TUI_EXECINFO_SIZE];
	...
	which is used to print the "B+>" bit, which is 3 chars wide.

	And there's the meaning of defining part of the size of the left margin:
	...
	  int left_margin () const
	  { return 1 + TUI_EXECINFO_SIZE + extra_margin (); }
	...
	where it represents 4 chars.

	The discrepancy between the two causes the space between "B+>" and
	"0x555555555151".

	Fix this by redefining TUI_EXECINFO_SIZE to 3, and using:
	...
	      char element[TUI_EXECINFO_SIZE + 1];
	...
	such that we have:
	...
	|B+>0x555555555151 <main+8>         lea    0xeac(%rip),%rax │
	...

	This changes the layout of the disassembly window back to what it was before
	commit 9e820dec13e ("Use a curses pad for source and disassembly windows"),
	the commit that introduced the PR30325 regression.

	This also changes the source window from:
	...
	│___000005__{                                               |

	[gdb/tui] Add maint set/show tui-left-margin-verbose
	The TUI has two types of windows derived from tui_source_window_base:
	- tui_source_window (the source window), and
	- tui_disasm_window (the disassembly window).

	The two windows share a common concept: the left margin.

	With a hello world a.out, we can see the source window:
	...
	┌─/home/vries/hello.c───────────────────────────────────────┐
	│        5  {                                               │

	│
	...
	where the left margin is the part holding "B+>" and the line number, and the
	disassembly window:
	...
	┌───────────────────────────────────────────────────────────┐
	│    0x555555555149 <main>           endbr64                │
	│    0x55555555514d <main+4>         push   %rbp            │
	│    0x55555555514e <main+5>         mov    %rsp,%rbp       │
	│B+> 0x555555555151 <main+8>         lea    0xeac(%rip),%rax│
	│    0x555555555158 <main+15>        mov    %rax,%rdi       │
	...
	where the left margin is just the bit holding "B+>".

	Because the left margin contains some spaces, it's not clear where it starts
	and ends, making it harder to observe problems related to it.

	Add a new maintenance command "maint set tui-left-margin-verbose", that when
	set to on replaces the spaces in the left margin with either '_' or '0',
	giving us this for the source window:
	...
	┌─/home/vries/hello.c───────────────────────────────────────┐

	│___000008__}                                               │
	...
	and this for the disassembly window:
	...
	┌───────────────────────────────────────────────────────────┐
	│___ 0x555555555149 <main>           endbr64                │

	│___ 0x555555555158 <main+15>        mov    %rax,%rdi       │
	...

	Note the space between "B+>" and 0x555555555151.  The space shows that a bit
	of the left margin is not written, a problem reported as PR tui/30325.

	Specifically, PR tui/30325 is about the fact that the '[' character from the
	string "[ No Assembly Available ]" ends up in that same spot:
	...
	│B+>[0x555555555151 <main+8>         lea    0xeac(%rip),%rax│
	...
	which only happens for certain window widths.

	The new command allows us to spot the problem with any window width.

	Likewise, when we revert the fix from commit 1b6d4bb2232 ("Redraw both spaces
	between line numbers and source code"), we have:
	...
	┌─/home/vries/hello.c───────────────────────────────────────┐

	pe_ILF_object_p and bfd_check_format_matches
	If pe_ILF_object_p succeeds, pe_ILF_build_a_bfd will have changed the
	bfd from being file backed to in-memory.  This can have unfortunate
	results for targets checked by bfd_check_format_matches after that
	point as they will be matching against the created in-memory image
	rather than the file.  bfd_preserve_restore also has a problem if it
	flips the BFD_IN_MEMORY flag, because the flag affects iostream
	meaning and should be set if using _bfd_memory_iovec.  To fix these
	problems, save and restore iostream and iovec along with flags, and
	modify bfd_reinit to make the bfd file backed again.  Restoring the
	iovec and iostream allows the hack in bfd_reinit keeping BFD_IN_MEMORY
	(part of BFD_FLAGS_SAVED) to be removed.
	One more detail: If restoring from file backed to in-memory then the
	bfd needs to be forcibly removed from the cache lru list, since after
	the bfd becomes in-memory a bfd_close will delete the bfd's memory
	leaving the lru list pointing into freed memory.

	bfd: optimize bfd_elf_hash
	The bfd_elf_hash loop is taken straight from the sysV document, but it
	is poorly optimized. This refactoring removes about 5 x86 insns from
	the 15 insn loop.

	1) The if (..) is meaningless -- we're xoring with that value, and of
	course xor 0 is a nop. On x86 (at least) we actually compute the xor'd
	value and then cmov.  Removing the if test removes the cmov.

	2) The 'h ^ g' to clear the top 4 bits is not needed, as those 4 bits
	will be shifted out in the next iteration.  All we need to do is sink
	a mask of those 4 bits out of the loop.

	3) anding with 0xf0 after shifting by 24 bits can allow betterin
	encoding on RISC ISAs than masking with '0xf0 << 24' before shifting.
	RISC ISAs often require materializing larger constants.

	gdb: warn when converting h/w watchpoints to s/w
	On amd64 (at least) if a user sets a watchpoint before the inferior
	has started then GDB will assume that a hardware watchpoint can be
	created.

	When the inferior starts there is a chance that the watchpoint can't
	actually be create as a hardware watchpoint, in which case (currently)
	GDB will silently convert the watchpoint to a software watchpoint.
	Here's an example session:

	  (gdb) p sizeof var
	  $1 = 4000
	  (gdb) watch var
	  Hardware watchpoint 1: var
	  (gdb) info watchpoints
	  Num     Type           Disp Enb Address    What
	  1       hw watchpoint  keep y              var
	  (gdb) starti
	  Starting program: /home/andrew/tmp/watch

	  Program stopped.
	  0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
	  (gdb) info watchpoints
	  Num     Type           Disp Enb Address            What
	  1       watchpoint     keep y                      var
	  (gdb)

	Notice that before the `starti` command the watchpoint is showing as a
	hardware watchpoint, but afterwards it is showing as a software
	watchpoint.  Additionally, note that we clearly told the user we
	created a hardware watchpoint:

	  (gdb) watch var
	  Hardware watchpoint 1: var

	I think this is bad.  I used `starti`, but if the user did `start` or
	even `run` then the inferior is going to be _very_ slow, which will be
	unexpected -- after all, we clearly told the user that we created a
	hardware watchpoint, and the manual clearly says that hardware
	watchpoints are fast (at least compared to s/w watchpoints).

	In this patch I propose adding a new warning which will be emitted
	when GDB downgrades a h/w watchpoint to s/w.  The session now looks
	like this:

	  (gdb) p sizeof var
	  $1 = 4000
	  (gdb) watch var
	  Hardware watchpoint 1: var
	  (gdb) info watchpoints
	  Num     Type           Disp Enb Address    What
	  1       hw watchpoint  keep y              var
	  (gdb) starti
	  Starting program: /home/andrew/tmp/watch
	  warning: watchpoint 1 downgraded to software watchpoint

	  Program stopped.
	  0x00007ffff7fd3110 in _start () from /lib64/ld-linux-x86-64.so.2
	  (gdb) info watchpoints
	  Num     Type           Disp Enb Address            What
	  1       watchpoint     keep y                      var
	  (gdb)

	The important line is:

	  warning: watchpoint 1 downgraded to software watchpoint

	It's not much, but hopefully it will be enough to indicate to the user
	that something unexpected has occurred, and hopefully, they will not
	be surprised when the inferior runs much slower than they expected.

	I've added an amd64 only test in gdb.arch/, I didn't want to try
	adding this as a global test as other architectures might be able to
	support the watchpoint request in h/w.

	Also the test is skipped for extended-remote boards as there's a
	different set of options for limiting hardware watchpoints on remote
	targets, and this test isn't about them.

	gdb/riscv: Support c.li in prologue unwinder
	I was seeing some failures in gdb.threads/omp-par-scope.exp when run
	on a riscv64 target.  It turns out the cause of the problem is that I
	didn't have debug information installed for libgomp.so, which this
	test makes use of.  The test requires GDB to backtrace through a
	libgomp function, and the riscv prologue unwinder was failing to
	unwind this particular stack frame.

	The reason for the failure to unwind was that the function prologue
	includes a c.li (compressed load immediate) instruction, and the riscv
	prologue scanning unwinder doesn't know what to do with this
	instruction, though the unwinder does understand c.lui (compressed
	load unsigned immediate).

	This commit adds support for c.li.  After this GDB is able to unwind
	through libgomp, and I no longer see any unexpected failures in
	gdb.threads/omp-par-scope.exp.

	I've also included a new test in gdb.arch/ which specifically checks
	for our c.li support.

	Handle unwinding from SEGV on Windows
	PR win32/30255 points out that a call to a NULL function pointer will

	I tracked this down to the amd64 windows unwinder.  If we treat this

	I'm not completely sure this patch is the best way.  I considered
	having it check for 'pc==0' -- but then I figured this could affect
	any inaccessible PC, not just the special 0 value.

	libctf, link: fix CU-mapped links with CTF_LINK_EMPTY_CU_MAPPINGS
	This is a bug in the intersection of two obscure options that cannot
	even be invoked from ld with a feature added to stop ld of the
	same input file repeatedly from crashing the linker.

	The latter fix involved tracking input files (internally to libctf) not
	just with their input CU name but with a version of their input CU name
	that was augmented with a numeric prefix if their linker input file name
	was changed, to prevent distinct CTF dicts with the same cuname from
	overwriting each other. (We can't use just the linker input file name
	because one linker input can contain many CU dicts, particularly under
	ld -r).  If these inputs then produced conflicting types, those types
	were emitted into similarly-named output dicts, so we needed similar
	machinery to detect clashing output dicts and add a numeric prefix to
	them as well.

	This works fine, except that if you used the cu-mapping feature to force
	double-linking of CTF (so that your CTF can be grouped into output dicts
	larger than a single translation unit) and then also used
	CTF_LINK_EMPTY_CU_MAPPINGS to force every possible output dict in the
	mapping to be created (even if empty), we did the creation of empty dicts
	first, and then all the actual content got considered to be a clash. So
	you ended up with a pile of useless empty dicts and then all the content
	was in full dicts with the same names suffixed with a #0.  This seems
	likely to confuse consumers that use this facility.

	Fixed by generating all the EMPTY_CU_MAPPINGS empty dicts after linking
	is complete, not before it runs.

	No impact on ld, which does not do cu-mapped links or pass
	CTF_LINK_EMPTY_CU_MAPPINGS to ctf_link().

	libctf/
		* ctf-link.c (ctf_create_per_cu): Don't create new dicts iff one
	        already exists and we are making one for no input in particular.
	        (ctf_link): Emit empty CTF dicts corresponding to no input in
	        particular only after linkiing is complete.

2023-04-08  Nick Alcock  <nick.alcock@oracle.com>

	libctf: propagate errors from parents correctly
	CTF dicts have per-dict errno values: as with other errno values these
	are set on error and left unchanged on success.  This means that all
	errors *must* set the CTF errno: if a call leaves it unchanged, the
	caller is apt to find a previous, lingering error and misinterpret
	it as the real error.

	There are many places in libctf where we carry out operations on parent
	dicts as a result of carrying out other user-requested operations on
	child dicts (e.g. looking up information on a pointer to a type will
	look up the type as well: the pointer might well be in a child and the
	type it's a pointer to in the parent).  Those operations on the parent
	might fail; if they do, the error must be correctly reflected on the
	child that the user-visible operation was carried out on.  In many
	places this was not happening.

	So, audit and fix all those places.  Add tests for as many of those
	cases as possible so they don't regress.

	libctf, tests: do not assume host and target have identical field offsets
	The newly-introduced libctf-lookup unnamed-field-info test checks
	C compiler-observed field offsets against libctf-computed ones
	by #including the testcase in the lookup runner as well as
	generating CTF for it.  This only works if the host, on which
	the lookup runner is compiled and executed, is the same architecture as
	the target, for which the CTF is generated: when crossing, the trick
	may fail.

	So pass down an indication of whether this is a cross into the
	testsuite, and add a new no_cross flag to .lk files that is used to
	suppress test execution when a cross-compiler is being tested.

	Clang with LTO (clang -flto) garbage collects unused global variables,
	Thus, gdb.base/align-c.exp and gdb.base/align-c++.exp fail with
	hundreds of FAILs like so:

	 $ make check \
	    TESTS="gdb.*/align-*.exp" \
	    RUNTESTFLAGS="CC_FOR_TARGET='clang -flto' CXX_FOR_TARGET='clang++ -flto'"

	 FAIL: gdb.base/align-c.exp: get integer valueof "a_char_x_unsigned_char"
	 ...

	AIX GCC has the same issue, and there the easier way of adding
	__attribute__((used)) to globals does not help.

	So add explicit uses of all globals to the generated code.

	For the C++ test, that reveals that the static variable members of the
	generated structs are not defined anywhere, leading to undefined
	references.  Fixed by emitting initialization for all static members.

	Lastly, I noticed that CXX_FOR_TARGET was being ignored -- that's
	because the align-c++.exp testcase is compiling with the C compiler
	driver.  Fixed by passing "c++" as option to prepare_for_testing.

	gdb/python: allow Frame.read_var to accept named arguments
	This commit allows Frame.read_var to accept named arguments, and also
	improves (I think) some of the error messages emitted when values of
	the wrong type are passed to this function.

	The read_var method takes two arguments, one a variable, which is
	either a gdb.Symbol or a string, while the second, optional, argument
	is always a gdb.Block.

	I'm now using 'O!' as the format specifier for the second argument,
	which allows the argument type to be checked early on.  Currently, if
	the second argument is of the wrong type then we get this error:

	  (gdb) python print(gdb.selected_frame().read_var("a1", "xxx"))
	  Traceback (most recent call last):
	    File "<string>", line 1, in <module>
	  RuntimeError: Second argument must be block.
	  Error while executing Python code.
	  (gdb)

	After this commit, we now get an error like this:

	  (gdb) python print(gdb.selected_frame().read_var("a1", "xxx"))
	  Traceback (most recent call last):
	    File "<string>", line 1, in <module>
	  TypeError: argument 2 must be gdb.Block, not str
	  Error while executing Python code.
	  (gdb)

	Changes are:

	  1. Exception type is TypeError not RuntimeError, this is unfortunate
	  as user code _could_ be relying on this, but I think the improvement
	  is worth the risk, user code relying on the exact exception type is
	  likely to be pretty rare,

	  2. New error message gives argument position and expected argument
	  type, as well as the type that was passed.

	If the first argument, the variable, has the wrong type then the
	previous exception was already a TypeError, however, I've updated the
	text of the exception to more closely match the "standard" error
	message we see above.  If the first argument has the wrong type then
	before this commit we saw this:

	  (gdb) python print(gdb.selected_frame().read_var(123))
	  Traceback (most recent call last):
	    File "<string>", line 1, in <module>
	  TypeError: Argument must be a symbol or string.
	  Error while executing Python code.
	  (gdb)

	And after we see this:

	  (gdb) python print(gdb.selected_frame().read_var(123))
	  Traceback (most recent call last):
	    File "<string>", line 1, in <module>
	  TypeError: argument 1 must be gdb.Symbol or str, not int
	  Error while executing Python code.
	  (gdb)

	For existing code that doesn't use named arguments and doesn't rely on
	exceptions, there will be no changes after this commit.

	gdb/python: convert Frame.read_register to take named arguments
	Following on from the previous commit, this updates
	Frame.read_register to accept named arguments.  As with the previous
	commit there's no huge benefit for the users in accepting named
	arguments here -- this function only takes a single argument after
	all.

	But I do think it is worth keeping Frame.read_register method in sync
	with the PendingFrame.read_register method, this allows for the
	possibility that the user has some code that can operate on either a
	Frame or a Pending frame.

	Minor update to allow for named arguments, and an extra test to check
	the new functionality.

	gdb/python: have PendingFrame methods accept keyword arguments
	Update the two gdb.PendingFrame methods gdb.PendingFrame.read_register
	and gdb.PendingFrame.create_unwind_info to accept keyword arguments.

	There's no huge benefit for making this change, both of these methods
	only take a single argument, so it is (maybe) less likely that a user
	will take advantage of the keyword arguments in these cases, but I
	think it's nice to be consistent, and I don't see any particular draw
	backs to making this change.

	For PendingFrame.read_register I've changed the argument name from
	'reg' to 'register' in the documentation and used 'register' as the
	argument name in GDB.  My preference for APIs is to use full words
	where possible, and given we didn't support named arguments before
	this change should not break any existing code.

	There should be no user visible changes (for existing code) after this
	commit.

	gdb/python: have UnwindInfo.add_saved_register accept named args
	Update gdb.UnwindInfo.add_saved_register to accept named keyword
	arguments.

	As part of this update we now use gdb_PyArg_ParseTupleAndKeywords
	instead of PyArg_UnpackTuple to parse the function arguments.

	By switching to gdb_PyArg_ParseTupleAndKeywords, we can now use 'O!'
	as the argument format for the function's value argument.  This means
	that we can check the argument type (is gdb.Value) as part of the
	argument processing rather than manually performing the check later in
	the function.  One result of this is that we now get a better error
	message (at least, I think so).  Previously we would get something
	like:

	  ValueError: Bad register value

	Now we get:

	  TypeError: argument 2 must be gdb.Value, not XXXX

	It's unfortunate that the exception type changed, but I think the new
	exception type actually makes more sense.

	My preference for argument names is to use full words where that's not
	too excessive.  As such, I've updated the name of the argument from
	'reg' to 'register' in the documentation, which is the argument name
	I've made GDB look for here.

	For existing unwinder code that doesn't throw any exceptions nothing
	should change with this commit.  It is possible that a user has some
	code that throws and catches the ValueError, and this code will break
	after this commit, but I think this is going to be sufficiently rare
	that we can take the risk here.

	gdb: fix reg corruption from displaced stepping on amd64
	This commit aims to address a problem that exists with the current
	approach to displaced stepping, and was identified in PR gdb/22921.

	Displaced stepping is currently supported on AArch64, ARM, amd64,
	i386, rs6000 (ppc), and s390.  Of these, I believe there is a problem
	with the current approach which will impact amd64 and ARM, and can
	lead to random register corruption when the inferior makes use of
	asynchronous signals and GDB is using displaced stepping.

	The problem can be found in displaced_step_buffers::finish in
	displaced-stepping.c, and is this; after GDB tries to perform a
	displaced step, and the inferior stops, GDB classifies the stop into
	one of two states, either the displaced step succeeded, or the
	displaced step failed.

	If the displaced step succeeded then gdbarch_displaced_step_fixup is
	called, which has the job of fixing up the state of the current
	inferior as if the step had not been performed in a displaced manner.
	This all seems just fine.

	However, if the displaced step is considered to have not completed
	then GDB doesn't call gdbarch_displaced_step_fixup, instead GDB
	remains in displaced_step_buffers::finish and just performs a minimal
	fixup which involves adjusting the program counter back to its
	original value.

	The problem here is that for amd64 and ARM setting up for a displaced
	step can involve changing the values in some temporary registers.  If
	the displaced step succeeds then this is fine; after the step the
	temporary registers are restored to their original values in the
	architecture specific code.

	But if the displaced step does not succeed then the temporary
	registers are never restored, and they retain their modified values.

	In this context a temporary register is simply any register that is
	not otherwise used by the instruction being stepped that the
	architecture specific code considers safe to borrow for the lifetime
	of the instruction being stepped.

	In the bug PR gdb/22921, the amd64 instruction being stepped is
	an rip-relative instruction like this:

	  jmp    *0x2fe2(%rip)

	When we displaced step this instruction we borrow a register, and
	modify the instruction to something like:

	  jmp    *0x2fe2(%rcx)

	with %rcx having its value adjusted to contain the original %rip
	value.

	Now if the displaced step does not succeed, then %rcx will be left
	with a corrupted value.  Obviously corrupting any register is bad; in
	the bug report this problem was spotted because %rcx is used as a
	function argument register.

	And finally, why might a displaced step not succeed?  Asynchronous
	signals provides one reason.  GDB sets up for the displaced step and,
	at that precise moment, the OS delivers a signal (SIGALRM in the bug
	report), the signal stops the inferior at the address of the displaced
	instruction.  GDB cancels the displaced instruction, handles the
	signal, and then tries again with the displaced step.  But it is that
	first cancellation of the displaced step that causes the problem; in
	that case GDB (correctly) sees the displaced step as having not
	completed, and so does not perform the architecture specific fixup,
	leaving the register corrupted.

	The reason why I think AArch64, rs600, i386, and s390 are not effected
	by this problem is that I don't believe these architectures make use
	of any temporary registers, so when a displaced step is not completed
	successfully, the minimal fix up is sufficient.

	On amd64 we use at most one temporary register.

	On ARM, looking at arm_displaced_step_copy_insn_closure, we could
	modify up to 16 temporary registers, and the instruction being
	displaced stepped could be expanded to multiple replacement
	instructions, which increases the chances of this bug triggering.

	This commit only aims to address the issue on amd64 for now, though I
	believe that the approach I'm proposing here might be applicable for
	ARM too.

	What I propose is that we always call gdbarch_displaced_step_fixup.

	We will now pass an extra argument to gdbarch_displaced_step_fixup,
	this a boolean that indicates whether GDB thinks the displaced step
	completed successfully or not.

	When this flag is false this indicates that the displaced step halted
	for some "other" reason.  On ARM GDB can potentially read the
	inferior's program counter in order figure out how far through the
	sequence of replacement instructions we got, and from that GDB can
	figure out what fixup needs to be performed.

	On targets like amd64 the problem is slightly easier as displaced
	stepping only uses a single replacement instruction.  If the displaced
	step didn't complete the GDB knows that the single instruction didn't
	execute.

	The point is that by always calling gdbarch_displaced_step_fixup, each
	architecture can now ensure that the inferior state is fixed up
	correctly in all cases, not just the success case.

	On amd64 this ensures that we always restore the temporary register
	value, and so bug PR gdb/22921 is resolved.

	In order to move all architectures to this new API, I have moved the
	minimal roll-back version of the code inside the architecture specific
	fixup functions for AArch64, rs600, s390, and ARM.  For all of these
	except ARM I think this is good enough, as no temporaries are used all
	that's needed is the program counter restore anyway.

	For ARM the minimal code is no worse than what we had before, though I
	do consider this architecture's displaced-stepping broken.

	I've updated the gdb.arch/amd64-disp-step.exp test to cover the
	'jmpq*' instruction that was causing problems in the original bug, and
	also added support for testing the displaced step in the presence of
	asynchronous signal delivery.

	I've also added two new tests (for amd64 and i386) that check that GDB
	can correctly handle displaced stepping over a single instruction that
	branches to itself.  I added these tests after a first version of this
	patch relied too much on checking the program-counter value in order
	to see if the displaced instruction had executed.  This works fine in
	almost all cases, but when an instruction branches to itself a pure
	program counter check is not sufficient.  The new tests expose this
	problem.

	bfd+ld: when / whether to generate .c files
	Having been irritated by seeing bfd/elf{32,64}-aarch64.c to be re-
	generated in x86-only builds, I came across 769a27ade588 ("Re: bfd
	BLD-POTFILES.in dependencies"). I think this went slightly too far, as
	outside of maintainer mode dependencies will cause the subset of files
	to be (re-)generated which are actually needed for the build.
	Generating them all is only needed when wanting to update certain files
	under bfd/po/, i.e. in maintainer mode.

	In the course of looking around in an attempt to try to understand how
	things are meant to work, I further noticed that ld has got things
	slightly wrong too: BLD-POTFILES.in depending on $(BLD_POTFILES) isn't
	quite right (the output doesn't change when any of the enumerated files
	changes; it's the mere presence which matters); like in bfd it looks
	like we would better extend BUILT_SOURCES accordingly.

	Furthermore it became apparent that ld fails to enumerate the .c files
	generated from the .l and .y ones. While in their absence it was benign
	whether translatable strings in the source files were actually marked as
	such, this now becomes relevant. Mark respective strings at the same
	time, but skipping ones which look to be of interest for debugging
	purposes only (e.g. such used by printf() enclosed in #ifdef TRACE).

	Use bfd_alloc memory for read_debugging_info storage
	Trying to free malloc'd memory used by the stabs and coff debug info
	parsers is complicated, and traversing the trees generated requires a
	lot of code.  It's better to bfd_alloc the memory which allows it all
	to be freed without fuss when the bfd is closed.  In the process of
	doing this I reverted most of commit a6336913332.

	Some of the stabs handling code grows arrays of pointers with realloc,
	to deal with arbitrary numbers of fields, function args, etc.  The
	code still does that but copies over to bfd_alloc memory when
	finished.  The alternative is to parse twice, once to size, then again
	to populate the arrays.  I think that complication is unwarranted.

	Note that there is a greater than zero chance this patch breaks
	something, eg. that I missed an attempt to free obj_alloc memory.
	Also it seems there are no tests in the binutils testsuite aimed at
	exercising objdump --debugging.

	gdb: cleanup around some set_momentary_breakpoint_at_pc calls
	I noticed a couple of places in infrun.c where we call
	set_momentary_breakpoint_at_pc, and then set the newly created
	breakpoint's thread field, these are in:

	  insert_exception_resume_breakpoint
	  insert_exception_resume_from_probe

	Function set_momentary_breakpoint_at_pc calls
	set_momentary_breakpoint, which always creates the breakpoint as
	thread-specific for the current inferior_thread().

	The two insert_* functions mentioned above take an arbitrary
	thread_info* as an argument and set the breakpoint::thread to hold the
	thread number of that arbitrary thread.

	However, the insert_* functions store the breakpoint pointer within
	the current inferior_thread(), so we know that the thread being passed
	in must be the currently selected thread.

	What this means is that we can:

	  1. Assert that the thread being passed in is the currently selected
	  thread, and

	  2. No longer adjust the breakpoint::thread field, this will already
	  have been set correctly be calling set_momentary_breakpoint_at_pc.

	There should be no user visible changes after this commit.

	gdb: don't always print breakpoint location after failed condition check
	Consider the following session:

	  (gdb) list some_func
	  1	int
	  2	some_func ()
	  3	{
	  4	  int *p = 0;
	  5	  return *p;
	  6	}
	  7
	  8	void
	  9	foo ()
	  10	{
	  (gdb) break foo if (some_func ())
	  Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
	  (gdb) r
	  Starting program: /tmp/bpcond

	  Program received signal SIGSEGV, Segmentation fault.
	  0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  Error in testing condition for breakpoint 1:
	  The program being debugged stopped while in a function called from GDB.
	  Evaluation of the expression containing the function
	  (some_func) will be abandoned.
	  When the function is done executing, GDB will silently stop.

	  Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  (gdb)

	What happens here is the breakpoint condition includes a call to an
	inferior function, and the inferior function segfaults.  We can see
	that GDB reports the segfault, and then gives an error message that
	indicates that an inferior function call was interrupted.

	After this GDB appears to report that it is stopped at Breakpoint 1,
	inside some_func.

	I find this second stop report a little confusing.  While it is true
	that GDB stopped as a result of hitting breakpoint 1, I think the
	message GDB currently prints might give the impression that GDB is
	actually stopped at a location of breakpoint 1, which is not the case.

	Also, I find the second stop message draws attention away from
	the "Program received signal SIGSEGV, Segmentation fault" stop
	message, and this second stop might be thought of as replacing in
	someway the earlier message.

	In short, I think things would be clearer if the second stop message
	were not reported at all, so the output should, I think, look like
	this:

	  (gdb) list some_func
	  1	int
	  2	some_func ()
	  3	{
	  4	  int *p = 0;
	  5	  return *p;
	  6	}
	  7
	  8	void
	  9	foo ()
	  10	{
	  (gdb) break foo if (some_func ())
	  Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
	  (gdb) r
	  Starting program: /tmp/bpcond

	  Program received signal SIGSEGV, Segmentation fault.
	  0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  Error in testing condition for breakpoint 1:
	  The program being debugged stopped while in a function called from GDB.
	  Evaluation of the expression containing the function
	  (some_func) will be abandoned.
	  When the function is done executing, GDB will silently stop.
	  (gdb)

	The user can still find the number of the breakpoint that triggered
	the initial stop in this line:

	  Error in testing condition for breakpoint 1:

	But there's now only one stop reason reported, the SIGSEGV, which I
	think is much clearer.

	To achieve this change I set the bpstat::print field when:

	  (a) a breakpoint condition evaluation failed, and

	  (b) the $pc of the thread changed during condition evaluation.

	I've updated the existing tests that checked the error message printed
	when a breakpoint condition evaluation failed.

	gdb: avoid repeated signal reporting during failed conditional breakpoint
	Consider the following case:

	  (gdb) list some_func
	  1	int
	  2	some_func ()
	  3	{
	  4	  int *p = 0;
	  5	  return *p;
	  6	}
	  7
	  8	void
	  9	foo ()
	  10	{
	  (gdb) break foo if (some_func ())
	  Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
	  (gdb) r
	  Starting program: /tmp/bpcond

	  Program received signal SIGSEGV, Segmentation fault.
	  0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  Error in testing breakpoint condition:
	  The program being debugged was signaled while in a function called from GDB.
	  GDB remains in the frame where the signal was received.
	  To change this behavior use "set unwindonsignal on".
	  Evaluation of the expression containing the function
	  (some_func) will be abandoned.
	  When the function is done executing, GDB will silently stop.

	  Program received signal SIGSEGV, Segmentation fault.

	  Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  (gdb)

	Notice that this line:

	  Program received signal SIGSEGV, Segmentation fault.

	Appears twice in the output.  The first time is followed by the
	current location.  The second time is a little odd, why do we print
	that?

	Printing that line is controlled, in part, by a global variable,
	stopped_by_random_signal.  This variable is reset to zero in
	handle_signal_stop, and is set if/when GDB figures out that the
	inferior stopped due to some random signal.

	The problem is, in our case, GDB first stops at the breakpoint for
	foo, and enters handle_signal_stop and the stopped_by_random_signal
	global is reset to 0.

	Later within handle_signal_stop GDB calls bpstat_stop_status, it is
	within this function (via bpstat_check_breakpoint_conditions) that the
	breakpoint condition is checked, and, we end up calling the inferior
	function (some_func in our example above).

	In our case above the thread performing the inferior function call
	segfaults in some_func.  GDB catches the SIGSEGV and handles the stop,
	this causes us to reenter handle_signal_stop.  The global variable
	stopped_by_random_signal is updated, this time it is set to true
	because the thread stopped due to SIGSEGV.  As a result of this we
	print the first instance of the line (as seen above in the example).

	Finally we unwind GDB's call stack, the inferior function call is
	complete, and we return to the original handle_signal_stop.  However,
	the stopped_by_random_signal global is still carrying the value as
	computed for the inferior function call's stop, which is why we now
	print a second instance of the line, as seen in the example.

	To prevent this, I propose adding a scoped_restore before we start an
	inferior function call.  This will save and restore the global
	stopped_by_random_signal value.

	With this done, the output from our example is now this:

	 (gdb) list some_func
	  1	int
	  2	some_func ()
	  3	{
	  4	  int *p = 0;
	  5	  return *p;
	  6	}
	  7
	  8	void
	  9	foo ()
	  10	{
	  (gdb) break foo if (some_func ())
	  Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
	  (gdb) r
	  Starting program: /tmp/bpcond

	  Program received signal SIGSEGV, Segmentation fault.
	  0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  Error in testing condition for breakpoint 1:
	  The program being debugged stopped while in a function called from GDB.
	  Evaluation of the expression containing the function
	  (some_func) will be abandoned.
	  When the function is done executing, GDB will silently stop.

	  Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  (gdb)

	We now only see the 'Program received signal SIGSEGV, ...' line once,
	which I think makes more sense.

	Finally, I'm aware that the last few lines, that report the stop as
	being at 'Breakpoint 1', when this is not where the thread is actually
	located anymore, is not great.  I'll address that in the next commit.

	gdbserver: allow agent expressions to fail with invalid memory access
	This commit extends gdbserver to take account of a failed memory
	access from agent_mem_read, and to return a new eval_result_type
	expr_eval_invalid_memory_access.

	I have only updated the agent_mem_read calls related directly to
	reading memory, I have not updated any of the calls related to
	tracepoint data collection.  This is just because I'm not familiar
	with that area of gdb/gdbserver, and I don't want to break anything,
	so leaving the existing behaviour untouched seems like the safest
	approach.

	I've then updated gdb.base/bp-cond-failure.exp to test evaluating the
	breakpoints on the target, and have also extended the test so that it
	checks for different sizes of memory access.

2023-04-03  Andrew Burgess  <aburgess@redhat.com>

	gdbserver: allows agent_mem_read to return an error code
	Currently the gdbserver function agent_mem_read ignores any errors
	from calling read_inferior_memory.  This means that if there is an
	attempt to access invalid memory then this will appear to succeed.

	In this patch I update agent_mem_read so that if read_inferior_memory
	fails, agent_mem_read will return an error code.

	However, none of the callers of agent_mem_read actually check the
	return value, so this commit will have no effect on anything.  In the
	next commit I will update the users of agent_mem_read to check for the
	error code.

	I've also updated the header comments on agent_mem_read to better
	reflect what the function does, and its possible return values.

	gdb: include breakpoint number in testing condition error message
	When GDB fails to test the condition of a conditional breakpoint, for
	whatever reason, the error message looks like this:

	  (gdb) break foo if (*(int *) 0) == 1
	  Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
	  (gdb) r
	  Starting program: /tmp/bpcond
	  Error in testing breakpoint condition:
	  Cannot access memory at address 0x0

	  Breakpoint 1, foo () at bpcond.c:11
	  11	  int a = 32;
	  (gdb)

	The line I'm interested in for this commit is this one:

	  Error in testing breakpoint condition:

	In the case above we can figure out that the problematic breakpoint
	was #1 because in the final line of the message GDB reports the stop
	at breakpoint #1.

	However, in the next few patches I plan to change this.  In some cases
	I don't think it makes sense for GDB to report the stop as being at
	breakpoint #1, consider this case:

	  (gdb) list some_func
	  1	int
	  2	some_func ()
	  3	{
	  4	  int *p = 0;
	  5	  return *p;
	  6	}
	  7
	  8	void
	  9	foo ()
	  10	{
	  (gdb) break foo if (some_func ())
	  Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
	  (gdb) r
	  Starting program: /tmp/bpcond

	  Program received signal SIGSEGV, Segmentation fault.
	  0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  Error in testing breakpoint condition:
	  The program being debugged was signaled while in a function called from GDB.
	  GDB remains in the frame where the signal was received.
	  To change this behavior use "set unwindonsignal on".
	  Evaluation of the expression containing the function
	  (some_func) will be abandoned.
	  When the function is done executing, GDB will silently stop.

	  Program received signal SIGSEGV, Segmentation fault.

	  Breakpoint 1, 0x0000000000401116 in some_func () at bpcond.c:5
	  5	  return *p;
	  (gdb)

	Notice that, the final lines of output reports the stop as being at
	breakpoint #1, even though the inferior in not located within
	some_func, and it's certainly not located at the breakpoint location.

	I find this behaviour confusing, and propose that this should be
	changed.  However, if I make that change then every reference to
	breakpoint #1 will be lost from the error message.

	So, in this commit, in preparation for the later commits, I propose to
	change the 'Error in testing breakpoint condition:' line to this:

	  Error in testing condition for breakpoint NUMBER:

	where NUMBER will be filled in as appropriate.  Here's the first
	example with the updated error:

	  (gdb) break foo if (*(int *) 0) == 0
	  Breakpoint 1 at 0x40111e: file bpcond.c, line 11.
	  (gdb) r
	  Starting program: /tmp/bpcond
	  Error in testing condition for breakpoint 1:
	  Cannot access memory at address 0x0

	  Breakpoint 1, foo () at bpcond.c:11
	  11	  int a = 32;
	  (gdb)

	The breakpoint number does now appear twice in the output, but I don't
	see that as a negative.

	This commit just changes the one line of the error, and updates the
	few tests that either included the old error in comments, or actually
	checked for the error in the expected output.

	As the only test that checked the line I modified is a Python test,
	I've added a new test that doesn't rely on Python that checks the
	error message in detail.

	While working on the new test, I spotted that it would fail when run
	with native-gdbserver and native-extended-gdbserver target boards.
	This turns out to be due to a gdbserver bug.  To avoid cluttering this
	commit I've added a work around to the new test script so that the
	test passes for the remote boards, in the next few commits I will fix
	gdbserver, and update the test script to remove the work around.

	gdb/riscv: fix regressions in gdb.base/unwind-on-each-insn.exp
	This commit builds on the previous one to fix all the remaining
	failures in gdb.base/unwind-on-each-insn.exp for RISC-V.

	The problem we have in gdb.base/unwind-on-each-insn.exp is that, when
	we are in the function epilogue, the previous frame and stack pointer
	values are being restored, and so, the values that we calculated
	during the function prologue are no longer suitable.

	Here's an example from the function 'bar' in the mentioned test.  This
	was compiled for 64-bit RISC-V with compressed instruction support:

	  Dump of assembler code for function bar:
	     0x000000000001018a <+0>:	add	sp,sp,-32
	     0x000000000001018c <+2>:	sd	ra,24(sp)
	     0x000000000001018e <+4>:	sd	fp,16(sp)
	     0x0000000000010190 <+6>:	add	fp,sp,32
	     0x0000000000010192 <+8>:	sd	a0,-24(fp)
	     0x0000000000010196 <+12>:	ld	a0,-24(fp)
	     0x000000000001019a <+16>:	jal	0x10178 <foo>
	     0x000000000001019e <+20>:	nop
	     0x00000000000101a0 <+22>:	ld	ra,24(sp)
	     0x00000000000101a2 <+24>:	ld	fp,16(sp)
	     0x00000000000101a4 <+26>:	add	sp,sp,32
	     0x00000000000101a6 <+28>:	ret
	  End of assembler dump.

	When we are at address 0x101a4 the previous instruction has restored
	the frame-pointer, as such GDB's (current) preference for using the
	frame-pointer as the frame base address is clearly not going to work.
	We need to switch to using the stack-pointer instead.

	At address 0x101a6 the previous instruction has restored the
	stack-pointer value.  Currently GDB will not understand this and so
	will still assume the stack has been decreased by 32 bytes in this
	function.

	My proposed solution is to extend GDB such that GDB will scan the
	instructions at the current $pc looking for this pattern:

	  ld    fp,16(sp)
	  add   sp,sp,32
	  ret

	Obviously the immediates can change, but the basic pattern indicates
	that the function is in the process of restoring state before
	returning.  If GDB sees this pattern then GDB can use the inferior's
	position within this instruction sequence to help calculate the
	correct frame-id.

	With this implemented then gdb.base/unwind-on-each-insn.exp now fully
	passes.

	Obviously what I've implemented is just a heuristic.  It's not going
	to work for every function.  If the compiler reorders the
	instructions, or merges the epilogue back into the function body then
	GDB is once again going to get the frame-id wrong.

	I'm OK with that, we're no worse off that we are right now in that
	situation (plus we can always improve the heuristic later).

	Remember, this is for debugging code without debug information,
	and (in our imagined situation) with more aggressive levels of
	optimisation being used.  Obviously GDB is going to struggle in these
	situations.

	My thinking is, lets get something in place now.  Then, later, if
	possible, we might be able to improve the logic to cover more
	situations -- if there's an interest in doing so.  But I figure we
	need something in place as a starting point.

	After this commit gdb.base/unwind-on-each-insn.exp passes with no
	failures on RV64.

	gdb/riscv: support c.ldsp and c.lwsp in prologue scanner
	Add support to the RISC-V prologue scanner for c.ldsp and c.lwsp
	instructions.

	This fixes some of the failures in gdb.base/unwind-on-each-insn.exp,
	though there are further failures that are not fixed by this commit.

	This change started as a wider fix that would address all the failures
	in gdb.base/unwind-on-each-insn.exp, however, that wider fix needed
	support for the two additional compressed instructions.

	When I added support for those two compressed instructions I noticed
	that some of the failures in gdb.base/unwind-on-each-insn.exp resolved
	themselves!

	Here's what's going on:

	The reason for the failures is that GDB is trying to build the
	frame-id during the last few instructions of the function.  These are
	the instructions that restore the frame and stack pointers just prior
	to the return instruction itself.

	By the time we reach the function epilogue the stack offset that we
	calculated during the prologue scan is no longer valid, and so we
	calculate the wrong frame-id.

	However, in the particular case of interest here, the test function
	'foo', the function is so simple and short (the empty function) that
	GDB's prologue scan could, in theory, scan every instruction of the
	function.

	I say "could, in theory," because currently GDB stops the prologue
	scan early when it hits an unknown instruction.  The unknown
	instruction happens to be one of the compressed instructions that I'm
	adding support for in this commit.

	Now that GDB understands the compressed instructions the prologue scan
	really does go from the start of the function right up to the current
	program counter.  As such, GDB sees that the stack frame has been
	allocated, and then deallocated, and so builds the correct frame-id.

	Of course, most real functions are not as simple as the test function
	'foo'.  As such, we can't usually rely on scanning right up to the end
	of the function -- there are some instructions we always need to stop
	at because GDB can't reason about how they change the inferior
	state (e.g. a function call).  The test function 'bar' is just such an
	example.

	After this commit, we can now build the frame-id correctly for every
	instruction in 'foo', but there are some tests still failing in 'bar'.

	gdb/riscv: convert riscv debug settings to new debug print scheme
	Convert the RISC-V specific debug settings to use the new debug

	  set/show debug riscv breakpoints
	  set/show debug riscv gdbarch
	  set/show debug riscv infcall
	  set/show debug riscv unwinder

	All of these settings now take a boolean rather than an integer, and
	all print their output using the new debug scheme.

	There should be no visible change for anyone not turning on debug.

	      [gdb/testsuite] Fix gdb.server/server-kill.exp for remote target

	The first of these commits fixed an issue in GDB and tried to extend
	the gdb.server/server-kill.exp test to cover the GDB fix.

	Unfortunately, the changes to gdb.server/server-kill.exp were not
	correct, and were causing problems when trying to run with the
	remote-gdbserver-on-localhost board file.

	The second commit reverts some of the gdb.server/server-kill.exp
	changes introduced in the first commit so that the test will now work
	correctly with the remote-gdbserver-on-localhost board file.

	The second commit is just about GDB's testing infrastructure -- it's
	not about the original fix to GDB from the first commit, the actual
	GDB change was fine.

	While reviewing the second commit I wanted to check that the problem
	fixed in the first commit is still being tested by the
	gdb.server/server-kill.exp script, so I reverted the change to
	breakpoint.c that is the core of the first commit and ran the test
	script ..... and saw no failures.

	The first commit is about GDB discovering that gdbserver has died
	while trying to insert a breakpoint.  As soon as GDB spots that
	gdbserver is gone we mourn the remote inferior, which ends up deleting
	all the breakpoints associated with the remote inferiors.  We then
	throw an exception which is caught in the insert breakpoints code, and
	we try to display an error that includes the breakpoint number
	.... but the breakpoint has already been deleted ... and so GDB
	crashes.

	After digging a little, what I found is that today, when the test does
	'stepi' the first thing we end up doing is calculating the frame-id as
	part of the stepi logic, it is during this frame-id calculation that
	we mourn the remote inferior, delete the breakpoints, and throw an
	exception.  The exception is caught by the top level interpreter loop,
	and so we never try to print the breakpoint number which is what
	caused the original crash.

	If I add an 'info frame' command to the test script, prior to killing
	gdbserver, then now when we 'stepi' GDB already has the frame-id
	calculated, and the first thing we do is try to insert the
	breakpoints, this will trigger the original bug.

	In order to reproduce this experiment you'll need to change a function
	in breakpoint.c, like this:

	  static void
	  rethrow_on_target_close_error (const gdb_exception &e)
	  {
	    return;
	  }

	Then run gdb.server/server-kill.exp with and without this patch.  You
	should find that without this patch there are zero test failures,
	while with this patch there will be one failure like this:

	  (gdb) PASS: gdb.server/server-kill.exp: test_stepi: info frame
	  Executing on target: kill -9 4513    (timeout = 300)
	  builtin_spawn -ignore SIGHUP kill -9 4513
	  stepi
	  ../../src/gdb/breakpoint.c:2863: internal-error: insert_bp_location: Assertion `bl->owner != nullptr' failed.
	  A problem internal to GDB has been detected,
	  further debugging may prove unreliable.

	gdb/testsuite: fix failure in gdb.python/py-unwind.exp
	A potential test failure was introduced with commit:

	  commit 6bf5f25bb150c0fbcb125e3ee466ba8f9680310b
	  Date:   Wed Mar 8 16:11:30 2023 +0000

	      gdb/python: make the gdb.unwinder.Unwinder class more robust

	In this commit a new test was added, however the expected output
	pattern varies depending on which Python version GDB is linked
	against.

	Older versions of Python result in output like this:

	    (gdb) python global_test_unwinder.name = "foo"
	    Traceback (most recent call last):
	      File "<string>", line 1, in <module>
	    AttributeError: can't set attribute
	    Error while executing Python code.
	    (gdb)

	While more recent versions of Python give a similar, but slightly more
	verbose error message, like this:

	    (gdb) python global_test_unwinder.name = "foo"
	    Traceback (most recent call last):
	      File "<string>", line 1, in <module>
	    AttributeError: can't set attribute 'name'
	    Error while executing Python code.
	    (gdb)

	The test was only accepting the first version of the output.  This
	commit extends the test pattern so that either version will be
	accepted.

	[aarch64] tpidr2: Fix erroneous detection logic for TPIDR2
	The detection logic for TPIDR2 was implemented incorrectly.  Originally
	the detection was supposed to be through a ptrace error code, but in reality,
	for backwards compatibility, the detection should be based on the size of
	the returned iovec.

	For instance, if a target supports both TPIDR and TPIDR2, ptrace will return a
	iovec size of 16.  If a target only supports TPIDR and not TPIDR2, it will
	return a iovec size of 8, even if we asked for 16 bytes.

	This patch fixes this issue in code that is shared between gdb and gdbserver,
	therefore both gdb and gdbserver are fixed.

	Tested on AArch64/Linux Ubuntu 20.04.

	gdb/arm: Fix backtrace for pthread_cond_timedwait
	GDB expected PC should point right after the SVC instruction when the
	syscall is active. But some active syscalls keep PC pointing to the SVC
	instruction itself.

	This leads to a broken backtrace like:
	 Backtrace stopped: previous frame identical to this frame (corrupt stack?)
	 #0  0xb6f8681c in pthread_cond_timedwait@@GLIBC_2.4 () from /lib/arm-linux-gnueabihf/libpthread.so.0
	 #1  0xb6e21f80 in ?? ()

	The reason is that .ARM.exidx unwinder gives up if PC does not point
	right after the SVC (syscall) instruction. I did not investigate why but
	some syscalls will point PC to the SVC instruction itself. This happens
	for the "futex" syscall used by pthread_cond_timedwait.

	That normally does not matter as ARM prologue unwinder gets called
	instead of the .ARM.exidx one. Unfortunately some glibc calls have more
	complicated prologue where the GDB unwinder fails to properly determine
	the return address (that is in fact an orthogonal GDB bug). I expect it
	is due to the "vpush" there in this case but I did not investigate it more:

	Dump of assembler code for function pthread_cond_timedwait@@GLIBC_2.4:
	   0xb6f8757c <+0>:     push    {r4, r5, r6, r7, r8, r9, r10, r11, lr}
	   0xb6f87580 <+4>:     mov     r10, r2

	However, that doesn't work as expected in this case because the initial
	gdb_test_multiple "define remove" fails to match all resulting output, and

	In the case where a Fortran program has a program name of "main" and
	there is also a minimal symbol called main, such as with programs built
	with GCC version 4.4.7 or below, the backtrace will erroneously stop at
	the minimal symbol rather than the user specified main, e.g.:

	(gdb) bt
	#0  bar () at .../gdb/testsuite/gdb.fortran/backtrace.f90:17
	#1  0x0000000000402556 in foo () at .../gdb/testsuite/gdb.fortran/backtrace.f90:21

	#3  0x00000000004025aa in main ()
	(gdb)

	This patch fixes this issue by increasing the precedence of the full
	symbol when the language of the current frame is Fortran.

	Newer versions of GCC transform the program name to "MAIN__" in this

	RISC-V: Allocate "various" operand type
	This commit intends to move operands that require very special handling or
	operand types that are so minor (e.g. only useful on a few instructions)
	under "W".  I also intend this "W" to be "temporary" operand storage until
	we can find good two character (or less) operand type.

	In this commit, prefetch offset operand "f" for 'Zicbop' extension is moved
	to "Wif" because of its special handling (and allocating single character
	"f" for this operand type seemed too much).

	Current expected allocation guideline is as follows:

	1.  'W'
	2.  The most closely related single-letter extension in lowercase
	    (strongly recommended but not mandatory)
	3.  Identify operand type

	The author currently plans to allocate following three-character operand
	types (for operands including instructions from unratified extensions).

	1.  "Wif" ('Zicbop': fetch offset)
	2.  "Wfv" (unratified 'Zfa': value operand from FLI.[HSDQ] instructions)
	3.  "Wfm" / "WfM"
	    'Zfh', 'F', 'D', 'Q': rounding modes "m" with special handling
	                          solely for widening conversion instructions.

	gas/ChangeLog:

		* config/tc-riscv.c (validate_riscv_insn, riscv_ip): Move from
		"f" to "Wif".

	opcodes/ChangeLog:

		* riscv-dis.c (print_insn_args): Move from "f" to "Wif".
		* riscv-opc.c (riscv_opcodes): Reflect new operand type.

	x86: convert testcases to use .insn
	This can't be done for all insns currently encoded with .byte. For one
	outside of 64-bit mode unused (typically ignored) register encoding bits
	in VEX/XOP/EVEX prefixes can't be set to their non-default values, since
	the necessary registers cannot be specified (and some of these bits
	can't even be used outside of 64-bit mode). And then there are odd tests
	like the first one in bad-bcast.s: Its purpose is to illegaly set EVEX.b
	together with EVEX.W (which could be expressed; note though EVEX.W set
	is invalid on its own), but then it also clears EVEX.B and EVEX.R' plus
	it sets EVEX.vvvv to other than 0xf (rendering the test ambiguous,
	because that's another #UD reason).

	In {,x86-64-}disassem.s many bogus encodings exist - some with ModR/M
	byte but insufficient displacement bytes, some using SIB encoding with
	the SIB byte actually being the supposed immediate. Some of these could
	be expressed by .insn, but I don't want to introduce bogus examples.
	These will all need adjustment anyway once the disassembler is improved
	in the way it deals with unrecognized encodings.

	Generally generated code is meant to remain the same. {,x86-64-}nops.d
	are exceptions because insn prefixes are emitted in a different order.
	opcode{,-intel,-suffix}.d are also adjusted (along with an according
	correction to opcode.s) to cover an apparent typo in the original tests
	(xor when or was meant).

	Where necessary --divide is added as gas option, to allow for the use
	of the extension opcode functionality.

	Comments are being adjusted where obviously wrong/misleading.

2023-03-31  Jan Beulich  <jbeulich@suse.com>

	x86: handle immediate operands for .insn
	Since we have no insn suffix and it's also not realistic to infer
	immediate size from the size of other (typically register) operands
	(like optimize_imm() does), and since we also don't have a template
	telling us permitted size(s), a new syntax construct is introduced to
	allow size (and signedness) specification. In the absence of such, the
	size is inferred from significant bits (which obviously may yield
	inconsistent results at least for effectively negative values, depending
	on whether BFD64 is enabled), and only if supplied expressions can be
	evaluated at parsing time. Being explicit is generally recommended to
	users.

	Size specification is permitted at bit granularity, but of course the
	eventually emitted immediate values will be padded up to 8-, 16-, 32-,
	or 64-bit fields.

	In particular the scaling factor cannot always be determined from pre-
	existing operand attributes. Introduce a new {:d<N>} vector operand

	(at least) otherwise ambiguous cases.

	x86: process instruction operands for .insn
	Deal with register and memory operands; immediate operands will follow

	Note that because we can't really know how to encode their use, %cr8 and
	up cannot be used with .insn outside of 64-bit mode. Users would need to
	specify an explicit LOCK prefix in combination with %cr0 etc.

	Note that on targets where / starts a comment, --divide needs passing to
	gas in order to make use of the extension opcode functionality.

	x86: parse VEX and alike specifiers for .insn
	All encoding spaces can be used this way; there's a certain risk that

	road, but people using .insn are expected to know what they're doing
	anyway. Plus this way there's at least _some_ way to have those bits
	set.

	For now this will only allow operand-less insns to be encoded this way.

	PR gdb/30219: Clear sync_quit_force_run in quit_force
	PR 30219 shows an internal error due to a "Bad switch" in

	contains cases for RETURN_QUIT and RETURN_ERROR, but is missing a case
	for the recently added RETURN_FORCED_QUIT.  This commit adds that case.

	Making the above change allows the errant test case to pass, but does

	0x5576e6a896dd quit_force(int*, int)
	        /home/smarchi/src/binutils-gdb/gdb/top.c:1849

	The real problem is in quit_force; here's the try/catch which
	eventually leads to the internal error:

	  /* Get out of tfind mode, and kill or detach all inferiors.  */
	  try
	    {
	      disconnect_tracing ();
	      for (inferior *inf : all_inferiors ())
		kill_or_detach (inf, from_tty);
	    }
	  catch (const gdb_exception &ex)
	    {
	      exception_print (gdb_stderr, ex);
	    }

	While running the calls in the try-block, a QUIT check is being
	performed.  This check finds that sync_quit_force_run is (still) set,
	causing a gdb_exception_forced_quit to be thrown.  The exception
	gdb_exception_forced_quit is derived from gdb_exception, causing
	exception_print to be called.  As shown by the backtrace,
	print_exception is then called, leading to the internal error.

	The actual fix, also implemented by this commit, is to clear
	sync_quit_force_run along with the quit flag.  This will allow the
	various cleanup code, called by quit_force, to run without triggering
	a gdb_exception_forced_quit.  (Though, if another SIGTERM is sent to
	the gdb process, these flags will be set again and a QUIT check in the
	cleanup code will detect it and throw the exception.)

	aarch64: Add the RPRFM instruction
	This patch adds the RPRFM (range prefetch) instruction.
	It was introduced as part of SME2, but it belongs to the
	prefetch hint space and so doesn't require any specific
	ISA flags.

	The aarch64_rprfmop_array initialiser (deliberately) only
	fills in the leading non-null elements.

	aarch64: Add the SVE FCLAMP instruction

	aarch64: Add new SVE shift instructions
	This patch adds the new SVE SQRSHRN, SQRSHRUN and UQRSHRN
	instructions.

	aarch64: Add new SVE saturating conversion instructions
	This patch adds the SVE SQCVTN, SQCVTUN and UQCVTN instructions,
	which are available when FEAT_SME2 is implemented.

	aarch64: Add new SVE dot-product instructions
	This patch adds the SVE FDOT, SDOT and UDOT instructions,
	which are available when FEAT_SME2 is implemented.  The patch
	also reorders the existing SVE_Zm3_22_INDEX to keep the
	operands numerically sorted.

	aarch64: Add the SVE BFMLSL instructions
	This patch adds the SVE BFMLSLB and BFMLSLT instructions,
	which are available when FEAT_SME2 is implemented.

	aarch64: Add the SME2 UZP and ZIP instructions
	This patch adds UZP and ZIP, which combine UZP{1,2} and ZIP{1,2}
	into single instructions.

	aarch64: Add the SME2 UNPK instructions
	This patch adds SUNPK and UUNPK, which unpack one register's
	worth of elements to two registers' worth, or two registers'
	worth to four registers' worth.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 shift instructions
	There are two instruction formats here:

	- SQRSHR, SQRSHRU and UQRSHR, which operate on lists of two
	  or four registers.

	- SQRSHRN, SQRSHRUN and UQRSHRN, which operate on lists of
	  four registers.

	These are the first SME2 instructions to have immediate operands.
	The patch makes sure that, when parsing SME2 instructions with
	immediate operands, the new predicate-as-counter registers are
	parsed as registers rather than as #-less immediates.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 FP<->FP conversion instructions
	This patch adds the BFCVT{,N} and FCVT{,N} instructions,
	which narrow a pair of .S registers to a single .H register.

	aarch64: Add the SME2 FP<->int conversion instructions
	This patch adds the SME2 versions of the FP<->integer conversion
	instructions FCVT* and *CVTF.  It also adds FP rounding instructions
	FRINT*, which share the same format.

	aarch64: Add the SME2 CLAMP instructions
	FCLAMP, SCLAMP and UCLAMP share the same format, although FCLAMP
	doesn't have a .B form.

	aarch64: Add the SME2 MOPA and MOPS instructions
	[BSU]MOP[AS] share the same format.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 vertical dot-product instructions
	There are three instruction formats here:
	- BFVDOT + FVDOT
	- SVDOT + UVDOT
	- SUVDOT + USVDOT

	There are also 64-bit forms of SVDOT and UVDOT.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 dot-product instructions
	BFDOT, FDOT and USDOT share the same instruction format.
	SDOT and UDOT share a different format.  SUDOT does not
	have the multi vector x multi vector forms, since they
	would be redundant with USDOT.

	aarch64: Add the SME2 MLALL and MLSLL instructions
	SMLALL, SMLSLL, UMLALL and UMLSLL have the same format.
	USMLALL and SUMLALL allow the same operand types as those
	instructions, except that SUMLALL does not have the multi-vector
	x multi-vector forms (which would be redundant with USMLALL).

	aarch64: Add the SME2 MLAL and MLSL instructions
	The {BF,F,S,U}MLAL and {BF,F,S,U}MLSL instructions share the same
	encoding.  They are the first instance of a ZA (as opposed to ZA tile)
	operand having a range of offsets.  As with ZA tiles, the expected
	range size is encoded in the operand-specific data field.

	aarch64: Add the SME2 FMLA and FMLS instructions

	aarch64: Add the SME2 maximum/minimum instructions
	This patch adds the SME2 multi-register forms of F{MAX,MIN}{,NM}
	and {S,U}{MAX,MIN}.  SQDMULH, SRSHL and URSHL have the same form
	as SMAX etc., so the patch adds them too.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 ADD and SUB instructions
	Add support for the SME2 ADD. SUB, FADD and FSUB instructions.
	SUB and FSUB have the same form as ADD and FADD, except that
	ADD also has a 2-operand accumulating form.

	The 64-bit ADD/SUB instructions require FEAT_SME_I16I64 and the
	64-bit FADD/FSUB instructions require FEAT_SME_F64F64.

	These are the first instructions to have tied register list
	operands, as opposed to tied single registers.

	The parse_operands change prevents unsuffixed Z registers (width==-1)
	from being treated as though they had an Advanced SIMD-style suffix
	(.4s etc.).  It means that:

	  Error: expected element type rather than vector type at operand 2 -- `add za\.s\[w8,0\],{z0-z1}'

	becomes:

	  Error: missing type suffix at operand 2 -- `add za\.s\[w8,0\],{z0-z1}'

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 ZT0 instructions
	SME2 adds lookup table instructions for quantisation.  They use
	a new lookup table register called ZT0.

	LUTI2 takes an unsuffixed SVE vector index of the form Zn[<imm>],
	which is the first time that this syntax has been used.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 predicate-related instructions
	Implementation-wise, the main things to note here are:

	- the WHILE* instructions have forms that return a pair of predicate
	  registers.  This is the first time that we've had lists of predicate
	  registers, and they wrap around after register 15 rather than after
	  register 31.

	- the predicate-as-counter WHILE* instructions have a fourth operand
	  that specifies the vector length.  We can treat this as an enumeration,
	  except that immediate values aren't allowed.

	- PEXT takes an unsuffixed predicate index of the form PN<n>[<imm>].
	  This is the first instance of a vector/predicate index having
	  no suffix.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 multivector LD1 and ST1 instructions
	SME2 adds LD1 and ST1 variants for lists of 2 and 4 registers.
	The registers can be consecutive or strided.  In the strided case,
	2-register lists have a stride of 8, starting at register x0xxx.
	4-register lists have a stride of 4, starting at register x00xx.

	The instructions are predicated on a predicate-as-counter register in
	the range pn8-pn15.  Although we already had register fields with upper
	bounds of 7 and 15, this is the first plain register operand to have a
	nonzero lower bound.  The patch uses the operand-specific data field
	to record the minimum value, rather than having separate inserters
	and extractors for each lower bound.  This in turn required adding
	an extra bit to the field.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add the SME2 MOVA instructions
	SME2 defines new MOVA instructions for moving multiple registers
	to and from ZA.  As with SME, the instructions are also available
	through MOV aliases.

	One notable feature of these instructions (and many other SME2
	instructions) is that some register lists must start at a multiple
	of the list's size.  The patch uses the general error "start register
	out of range" when this constraint isn't met, rather than an error
	specifically about multiples.  This ensures that the error is
	consistent between these simple consecutive lists and later
	strided lists, for which the requirements aren't a simple multiple.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add support for predicate-as-counter registers
	SME2 adds a new format for the existing SVE predicate registers:
	predicates as counters rather than predicates as masks.  In assembly
	code, operands that interpret predicates as counters are written
	pn<N> rather than p<N>.

	This patch adds support for these registers and extends some
	existing instructions to support them.  Since the new forms
	are just a programmer convenience, there's no need to make them
	more restrictive than the earlier predicate-as-mask forms.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64; Add support for vector offset ranges
	Some SME2 instructions operate on a range of consecutive ZA vectors.
	This is indicated by syntax such as:

	   za[<Wv>, <imml>:<immh>]

	Like with the earlier vgx2 and vgx4 support, we get better error
	messages if the parser allows all ZA indices to have a range.
	We can then reject invalid cases during constraint checking.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add support for vgx2 and vgx4
	Many SME2 instructions operate on groups of 2 or 4 ZA vectors.
	This is indicated by adding a "vgx2" or "vgx4" group size to the
	ZA index.  The group size is optional in assembly but preferred
	for disassembly.

	There is not a binary distinction between mnemonics that have
	group sizes and mnemonics that don't, nor between mnemonics that
	take vgx2 and mnemonics that take vgx4.  We therefore get better
	error messages if we allow any ZA index to have a group size
	during parsing, and wait until constraint checking to reject
	invalid sizes.

	A quirk of the way errors are reported means that if an instruction
	is wrong both in its qualifiers and its use of a group size, we'll
	print suggested alternative instructions that also have an incorrect
	group size.  But that's a general property that also applies to
	things like out-of-range immediates.  It's also not obviously the
	wrong thing to do.  We need to be relatively confident that we're
	looking at the right opcode before reporting detailed operand-specific
	errors, so doing qualifier checking first seems resonable.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add _off4 suffix to AARCH64_OPND_SME_ZA_array
	SME2 adds various new fields that are similar to
	AARCH64_OPND_SME_ZA_array, but are distinguished by the size of
	their offset fields.  This patch adds _off4 to the name of the
	field that we already have.

	aarch64: Add a _10 suffix to FLD_imm3
	SME2 adds various new 3-bit immediate fields, so this patch adds
	an lsb position suffix to the name of the field that we already have.

	aarch64: Add +sme2
	This patch adds bare-bones support for +sme2.  Later patches
	fill in the rest.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Prefer register ranges & support wrapping
	Until now, binutils has supported register ranges such
	as { v0.4s - v3.4s } as an unofficial shorthand for
	{ v0.4s, v1.4s, v2.4s, v3.4s }.  The SME2 ISA embraces this form
	and makes it the preferred disassembly.  It also embraces wrapped
	lists such as { z31.s - z2.s }, which is something that binutils
	didn't previously allow.

	The range form was already binutils's preferred disassembly for 3- and
	4-register lists.  This patch prefers it for 2-register lists too.
	The patch also adds support for wrap-around.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add support for strided register lists
	SME2 has instructions that accept strided register lists,
	such as { z0.s, z4.s, z8.s, z12.s }.  The purpose of this
	patch is to extend binutils to support such lists.

	The parsing code already had (unused) support for strides of 2.
	The idea here is instead to accept all strides during parsing
	and reject invalid strides during constraint checking.

	The SME2 instructions that accept strided operands also have
	non-strided forms.  The errors about invalid strides therefore
	take a bitmask of acceptable strides, which allows multiple
	possibilities to be summed up in a single message.

	I've tried to update all code that handles register lists.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Sort fields alphanumerically
	This patch just sorts the field enum alphanumerically, which makes
	it easier to see if a particular field has already been defined.

	aarch64: Resync field names
	This patch just makes the comments in aarch64-opc.c:fields match
	the names of the associated FLD_* enum.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Regularise FLD_* suffixes
	Some FLD_imm* suffixes used a counting scheme such as FLD_immN,
	FLD_immN_2, FLD_immN_3, etc., while others used the lsb as the
	suffix.  The latter seems more mnemonic, and was a big help
	in doing the SME2 work.

	Similarly, the _10 suffix on FLD_SME_size_10 was nonobvious.
	Presumably it indicated a 2-bit field, but it actually starts
	in bit 22.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Rename some of GAS's REG_TYPE_* macros
	In GAS, the vector and predicate registers are identified by
	REG_TYPE_VN, REG_TYPE_ZN and REG_TYPE_PN.  This "N" is obviously
	a placeholder for the register number.  However, we don't use that
	convention for integer and FP registers, and (more importantly)
	SME2 adds "predicate-as-counter" registers that are denoted PN.

	This patch therefore drops the "N" suffix from the existing
	registers.  The main hitch is that Z was also used for the
	zero register in things like R_Z, but using ZR seems more
	consistent with the SP-based names.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add a aarch64_cpu_supports_inst_p helper
	Quite a lot of SME2 instructions have an opcode bit that selects
	between 32-bit and 64-bit forms of an instruction, with the 32-bit
	forms being part of base SME2 and with the 64-bit forms being part
	of an optional extension.  It's nevertheless useful to have a single
	opcode entry for both forms since (a) that matches the ISA definition
	and (b) it tends to improve error reporting.

	This patch therefore adds a libopcodes function called
	aarch64_cpu_supports_inst_p that tests whether the target
	supports a particular instruction.  In future it will depend
	on internal libopcodes routines.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Reorder some OP_SVE_* macros
	This patch just moves some out-of-order-looking OP_SVE_* macros.

	aarch64: Rename aarch64-tbl.h OP_SME_* macros
	This patch renames the OP_SME_* macros in aarch64-tbl.h so that
	they follow the same scheme as the OP_SVE_* ones.  It also uses
	OP_SVE_ as the prefix, since there is no real distinction between
	the SVE and SME uses of qualifiers: a macro defined for one can
	be useful for the other too.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Tweak priorities of parsing-related errors
	There are three main kinds of error reported during parsing,
	in increasing order of priority:

	- AARCH64_OPDE_RECOVERABLE (register seen instead of immediate)
	- AARCH64_OPDE_SYNTAX_ERROR
	- AARCH64_OPDE_FATAL_SYNTAX_ERROR

	This priority makes sense when comparing errors reported against the
	same operand.  But if we get to operand 3 (say) and see a register
	instead of an immediate, that's likely to be a better match than
	something that fails with a syntax error at operand 1.

	The idea of this patch is to prioritise parsing-related errors
	based on operand index first, then by error code.  Post-parsing
	errors still win over parsing errors, and their relative priorities
	don't change.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Try to report invalid variants against the closest match
	If an instruction has invalid qualifiers, GAS would report the
	error against the final opcode entry that got to the qualifier-
	checking stage.  It seems better to report the error against
	the opcode entry that had the closest match, just like we
	pick the closest match within an opcode entry for the
	"did you mean this?" message.

	This patch adds the number of invalid operands as an
	argument to AARCH64_OPDE_INVALID_VARIANT and then picks the
	AARCH64_OPDE_INVALID_VARIANT with the lowest argument.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Tweak register list errors
	The error for invalid register lists had the form:

	  invalid number of registers in the list; N registers are expected at operand M -- `insn'

	This seems a bit verbose.  Also, the "bracketing" is really:

	  (invalid number of registers in the list; N registers are expected) at operand M

	but the semicolon works against that.

	This patch goes for slightly shorter messages, setting a template
	that later patches can use for more complex cases.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Make AARCH64_OPDE_REG_LIST take a bitfield
	AARCH64_OPDE_REG_LIST took a single operand that specified the
	expected number of registers.  However, there are quite a few
	SME2 instructions that have both 2-register forms and (separate)
	4-register forms.  If the user tries to use a 3-register list,
	it isn't obvious which opcode entry they meant.  Saying that we
	expect 2 registers and saying that we expect 4 registers would
	both be wrong.

	This patch therefore switches the operand to a bitfield.  If a
	AARCH64_OPDE_REG_LIST is reported against multiple opcode entries,
	the patch ORs up the expected lengths.

	This has no user-visible effect yet.  A later patch adds more error
	strings, alongside tests that use them.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Add an operand class for SVE register lists
	SVE register lists were classified as SVE_REG, since there had been
	no particular reason to separate them out.  However, some SME2
	instructions have tied register list operands, and so we need to
	distinguish registers and register lists when checking whether two
	operands match.

	Also, the register list operands used a general error message,
	even though we already have a dedicated error code for register
	lists that are the wrong length.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Commonise checks for index operands
	This patch splits out the constraint checking for index operands,
	so that it can be reused by new SME2 operands.

	aarch64: Add an error code for out-of-range registers
	libopcodes currently reports out-of-range registers as a general
	AARCH64_OPDE_OTHER_ERROR.  However, this means that each register
	range needs its own hard-coded string, which is a bit cumbersome
	if the range is determined programmatically.  This patch therefore
	adds a dedicated error type for out-of-range errors.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Deprioritise AARCH64_OPDE_REG_LIST
	SME2 has many instructions that take a list of SVE registers.
	There are often multiple forms, with different forms taking
	different numbers of registers.

	This means that if, after a successful parse and qualifier match,
	we find that the number of registers does not match the opcode entry,
	the associated error should have a lower priority/severity than other
	errors reported at the same stage.  For example, if there are 2-register
	and 4-register forms of an instruction, and if the assembly code uses
	the 2-register form with an out-of-range value, the out-of-range value
	error against the 2-register instruction should have a higher priority
	than the "wrong number of registers" error against the 4-register
	instruction.

	This is tested by the main SME2 patches, but seemed worth splitting out.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Update operand_mismatch_kind_names
	The contents of operand_mismatch_kind_names were out of sync
	with the enum.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Rework reporting of failed register checks
	There are many opcode table entries that share the same mnemonic.
	Trying to parse an invalid assembly line will trigger an error for
	each of these entries, but the specific error might vary from one
	entry to another, depending on the exact nature of the problem.

	GAS has quite an elaborate system for picking the most appropriate
	error out of all the failed matches.  And in many cases it works well.
	However, one of the limitations is that the error is always reported
	against a single opcode table entry.  If that table entry isn't the
	one that the user intended to use, then the error can end up being
	overly specific.

	This is particularly true if an instruction has a typoed register
	name, or uses a type of register that is not accepted by any
	opcode table entry.  For example, one of the expected error
	matches for an attempted SVE2 instruction is:

	  Error: operand 1 must be a SIMD scalar register -- `addp z32\.s,p0/m,z32\.s,z0\.s'

	even though the hypothetical user was presumably attempting to use
	the SVE form of ADDP rather than the Advanced SIMD one.  There are
	many other instances of this in the testsuite.

	The problem becomes especially acute with SME2, since many SME2
	instructions reuse existing mnemonics.  This could lead to us
	reporting an SME-related error against a non-SME instruction,
	or a non-SME-related error against an SME instruction.

	This patch tries to improve things by collecting together all
	the register types that an opcode table entry expected for a
	given operand.  It also records what kind of register was
	actually seen, if any.  It then tries to summarise all this
	in a more directed way, falling back to a generic error if
	the combination defies a neat summary.

	The patch includes tests for all new messages except REG_TYPE_ZA,
	which only triggers with SME2.

	To test this, I created an assembly file that contained the cross
	product of all known mnemonics and one example from each register
	class.  I then looked for cases where the new routines fell back on the
	generic errors ("expected a register" or "unexpected register type").
	I locally added dummy messages for each one until there were no
	more hits.  The patch adds a specimen instruction to diagnostics.s
	for each of these combinations.  In each case, the combination didn't
	seem like something that could be summarised in a natural way, so the
	generic messages seemed better.  There's always going to be an element
	of personal taste around this kind of thing though.

	Adding more register types made 1<<REG_TYPE_MAX exceed the range

	aarch64: Try to avoid inappropriate default errors
	After parsing a '{' and the first register, parse_typed_reg would
	report errors in subsequent registers in the same way as for the
	first register.  It used set_default_error, which reports errors
	of the form "operand N must be X".

	The problem is that if there are multiple opcode entries for the
	same mnemonic, there could be several matches that lead to a
	default error.  There's no guarantee that the default error for
	the register list is the one that will be chosen.

	To take an example from the testsuite:

	    ext z0.b,{z31.b,z32.b},#0

	gave:

	    operand 2 must be an SVE vector register

	with the error being reported against the single-vector version
	of ext, even though the operand is clearly a list.

	This patch uses set_fatal_syntax_error to bump the priority of the
	error once we're sure that the operand is a list of the right type.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Improve errors for malformed register lists
	parse_typed_reg is used for parsing both bare registers and
	registers that occur in lists.  If it doesn't see a register,
	or sees an unexpected kind of register, it queues a default
	error to report the problem.  These default errors have the form
	"operand N must be an X", where X comes from the operand table.

	If there are multiple opcode entries that report default errors,
	GAS tries to pick the most appropriate one, using the opcode
	table order as a tiebreaker.  But this can lead to cases where
	a syntax error in a register list is reported against an opcode
	that doesn't accept register lists.  For example, the unlikely
	error:

	  ext z0.b,{,},#0

	is reported as:

	  operand 2 must be an SVE vector register -- `ext z0.b,{,},#0'

	even though operand 2 can be a register list.

	If we've parsed the opening '{' of a register list, and then see
	something that isn't remotely register-like, it seems better to
	report that directly as a syntax error, rather than rely on the
	default error.  The operand won't be a valid list of anything,
	so there's no need to pick a specific Y in "operand N must be
	a list of Y".

	aarch64: Tweak parsing of integer & FP registers
	Integer registers were parsed indirectly through
	aarch64_reg_parse_32_64 (and thus aarch64_addr_reg_parse) rather
	than directly through parse_reg.  This was because we need the
	qualifier associated with the register, and the logic to calculate
	that was buried in aarch64_addr_reg_parse.

	The code that parses FP registers had the same need, but it
	open-coded the calculation of the qualifier.

	This patch tries to handle both cases in the same way.  It is
	needed by a later patch that tries to improve the register-related
	diagnostics.

	aarch64: Tweak errors for base & offset registers
	parse_address_main currently uses get_reg_expected_msg to
	report invalid base and offset registers, but the disadvantage
	of doing that is that it isn't immediately clear which register
	is wrong (the base or the offset).

	A later patch moves away from using get_reg_expected_msg for failed
	type checks, but doing that here didn't seem like the best approach.
	The patch tries to use more tailored messages instead.

	aarch64: Move w12-w15 range check to libopcodes
	In SME, the vector select register had to be in the range
	w12-w15, so it made sense to enforce that during parsing.
	However, SME2 adds instructions for which the range is
	w8-w11 instead.

	This patch therefore moves the range check from the parsing
	stage to the constraint-checking stage.

	Also, the previous error used a capitalised range W12-W15,
	whereas other register range errors used lowercase ranges
	like p0-p7.  A quick internal poll showed a preference for
	the lowercase form, so the patch uses that.

	The patch uses "selection register" rather than "vector
	select register" so that the terminology extends more
	naturally to PSEL.

	aarch64: Consolidate ZA slice parsing
	Now that parse_typed_reg checks the range of tile register numbers
	and libopcodes checks the range of vector select offsets, there's
	very little difference between the parsing of ZA tile indices,
	ZA array indices, and PSEL indices.  The main one is that ZA
	array indices don't currently allow "za" to be qualified,
	but we need to remove that restriction for SME2.

	This patch therefore consolidates all three parsers into a single
	routine, parameterised by the type of register that they expect.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Move ZA range checks to aarch64-opc.c
	This patch moves the range checks on ZA vector select offsets from
	gas to libopcodes.  Doing the checks there means that the error
	messages contain the expected range.  It also fits in better
	with the error severity scheme, which becomes important later.
	(This is because out-of-range indices are treated as more severe than
	syntax errors, on the basis that parsing must have succeeded if we get
	to the point of checking the completed opcode.)

	The patch also adds a new check_za_access function for checking
	ZA accesses.  That's a bit over the top for one offset check, but the
	function becomes more complex with later patches.

	sme-9-illegal.s checked for an invalid .q suffix using:

	  psel p1, p15, p3.q[w15]

	but this is doubly invalid because it misses the immediate part
	of the index.  The patch keeps that test but adds another with
	a zero index, so that .q is the only thing wrong.

	The aarch64-tbl.h change includes neatening up the backslash
	positions.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Pass aarch64_indexed_za to parsers
	ZA indices have more parts than most operands, so passing these
	parts around individually is more awkward than for other operand
	types.  Things aren't too bad at the moment, but SME2 adds two
	further pieces: an offset range and a vector group size.

	This patch therefore replaces arguments for the individual pieces
	with a single argument for the index as a whole.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Make indexed_za use 64-bit immediates
	A later patch moves the range checking for ZA vector select
	offsets from gas to libopcodes.  That in turn requires the
	immediate field to be big enough to support all parsed values.

	This shouldn't be a particularly size-sensitive structure,
	so there should be no memory problems with doing this.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Rename za_tile_vector to za_index
	za_tile_vector is also used for indexing ZA as a whole, rather than
	just for indexing tiles.  The former is more common than the latter
	in SME2, so this patch generalises the name to "indexed_za".

	The patch also names the associated structure, so that later patches
	can reuse it during parsing.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Treat ZA as a register
	We already treat the ZA tiles ZA0-ZA15 as registers.  This patch
	does the same for ZA itself.  parse_sme_zero_mask can then parse
	ZA tiles and ZA in the same way, through parsed_type_reg.

	One important effect of going through parsed_type_reg (in general)
	is that it allows ZA to take qualifiers.  This is necessary for many
	SME2 instructions.

	However, to support existing unqualified uses of ZA, parse_reg_with_qual
	needs to treat the qualiier as optional.  Hopefully the net effect is
	to give better error messages, since now that SME2 makes "za.<T>"
	valid in some contexts, it might be natural to use it (incorrectly)
	in ZERO too.

	While there, the patch also tweaks the error messages for invalid
	ZA tiles, to try to make some cases more specific.

	For now, parse_sme_za_array just uses parse_reg, rather than
	parse_typed_reg/parse_reg_with_qual.  A later patch consolidates
	the parsing further.

2023-03-30  Richard Sandiford  <richard.sandiford@arm.com>

	aarch64: Consolidate ZA tile range checks
	Now that all parsing of ZA tile names goes through parse_typed_reg,
	we can check there for out-of-range tile numbers.  The other check
	performed by parse_sme_zada_operand was to reject .q, but that can
	now be done via F_STRICT instead.  (.q tiles are valid in other
	contexts, so they shouldn't be rejected in parse_typed_reg.)

	aarch64: Reuse parse_typed_reg for ZA tiles
	This patch reuses the general parse_typed_reg for ZA tiles.
	This involves adding a way of suppressing the usual treatment
	of register indices, since ZA indices look very different from
	Advanced SIMD and SVE vector indices.

	aarch64: Rework parse_typed_reg interface
	parse_typed_reg returned a register number and passed the
	register type back using a pointer parameter.  It seems simpler
	to return the register entry instead, since that has both pieces
	of information in one place.

	The patch also replaces the boolean in_reg_list parameter with
	a mask of flags.  This hopefully makes calls easier to read
	(more self-documenting than "true" or "false"), but more
	importantly, it allows a later patch to add a second flag.

	The ZA tile registers were called REG_TYPE_ZA, REG_TYPE_ZAH and

	a register type too, and REG_TYPE_ZA is the obvious name for that.

	This patch therefore adds "T" (tile) to the existing names.

	aarch64: Use aarch64_operand_error more widely
	GAS's aarch64_instruction had its own cut-down error record,
	but it's better for later patches if it reuses the binutils-wide
	aarch64_operand_error instead.  The main difference is that
	aarch64_operand_error can store arguments to the error while
	aarch64_instruction couldn't.

	aarch64: Make SME instructions use F_STRICT
	This patch makes all SME instructions use F_STRICT, so that qualifiers
	have to be provided explicitly rather than being inferred from other
	operands.  The main change is to move the qualifier setting from the
	operand-level decoders to the opcode level.

	This is one step towards consolidating the ZA parsing code and
	extending it to handle SME2.

	aarch64: Fix SVE2 register/immediate distinction
	GAS refuses to interpret register names like x0 as unadorned
	immediates, due to the obvious potential for confusion with
	register operands.  (An explicit #x0 is OK.)

	For compatibility reasons, we can't extend the set of registers
	that GAS rejects for existing instructions.  For example:

	   mov x0, z0

	was valid code before SVE was added, so it needs to stay valid
	code even when SVE is enabled.  But we can make GAS reject newer
	registers in newer instructions.  The SVE instruction:

	   and z0.s, z0.s, z0.h

	is therefore invalid, rather than z0.h being an immediate.

	This patch extends the SVE behaviour to SVE2.  The old call
	to AARCH64_CPU_HAS_FEATURE was technically the wrong way around,
	although it didn't matter in practice for base SVE instructions
	since their avariants only set SVE.

	gdb/python: Add new gdb.unwinder.FrameId class
	When writing an unwinder it is necessary to create a new class to act
	as a frame-id.  This new class is almost certainly just going to set a

	This commit adds a little helper class gdb.unwinder.FrameId that does
	this job.  Users can make use of this to avoid having to write out
	standard boilerplate code any time they write an unwinder.

	Of course, if the user wants their FrameId class to be more
	complicated in some way, then they can still write their own class,
	just like they could before.

	I've simplified the example code in the documentation to now use the

	testsuite.

	Any existing user code will continue to work just as it did before
	after this change.

	gdb/python: Allow gdb.UnwindInfo to be created with non gdb.Value args
	Currently when creating a gdb.UnwindInfo object a user must call
	gdb.PendingFrame.create_unwind_info and pass a frame-id object.

	The frame-id object should have at least a 'sp' attribute, and
	probably a 'pc' attribute too (it can also, in some cases have a
	'special' attribute).

	Currently all of these frame-id attributes need to be gdb.Value
	objects, but the only reason for that requirement is that we have some
	code in py-unwind.c that only handles gdb.Value objects.

	If instead we switch to using get_addr_from_python in py-utils.c then
	we will support both gdb.Value objects and also raw numbers, which
	might make things simpler in some cases.

	So, I started rewriting pyuw_object_attribute_to_pointer (in
	py-unwind.c) to use get_addr_from_python.  However, while looking at
	the code I noticed a problem.

	The pyuw_object_attribute_to_pointer function returns a boolean flag,
	if everything goes OK we return true, but we return false in two
	cases, (1) when the attribute is not present, which might be
	acceptable, or might be an error, and (2) when we get an error trying
	to extract the attribute value, in which case a Python error will have
	been set.

	Now in pending_framepy_create_unwind_info we have this code:

	  if (!pyuw_object_attribute_to_pointer (pyo_frame_id, "sp", &sp))
	    {
	      PyErr_SetString (PyExc_ValueError,
			       _("frame_id should have 'sp' attribute."));
	      return NULL;
	    }

	Notice how we always set an error.  This will override any error that
	is already set.

	So, if you create a frame-id object that has an 'sp' attribute, but
	the attribute is not a gdb.Value, then currently we fail to extract
	the attribute value (it's not a gdb.Value) and set this error in
	pyuw_object_attribute_to_pointer:

	  rc = pyuw_value_obj_to_pointer (pyo_value.get (), addr);
	  if (!rc)
	    PyErr_Format (
	        PyExc_ValueError,
	        _("The value of the '%s' attribute is not a pointer."),
	        attr_name);

	Then we return to pending_framepy_create_unwind_info and immediately
	override this error with the error about 'sp' being missing.

	This all feels very confused.

	Here's my proposed solution: pyuw_object_attribute_to_pointer will now
	return a tri-state enum, with states OK, MISSING, or ERROR.  The
	meanings of these states are:

	  OK - Attribute exists and was extracted fine,

	  MISSING - Attribute doesn't exist, no Python error was set.

	  ERROR - Attribute does exist, but there was an error while
	     extracting it, a Python error was set.

	We need to update pending_framepy_create_unwind_info, the only user of
	pyuw_object_attribute_to_pointer, but now I think things are much
	clearer.  Errors from lower levels are not blindly overridden with the
	generic meaningless error message, but we still get the "missing 'sp'
	attribute" error when appropriate.

	This change also includes the switch to get_addr_from_python which was
	what started this whole journey.

	For well behaving user code there should be no visible changes after
	this commit.

	For user code that hits an error, hopefully the new errors should be
	more helpful in figuring out what's gone wrong.

	Additionally, users can now use integers for the 'sp' and 'pc'
	attributes in their frame-id objects if that is useful.

	gdb: have value_as_address call unpack_pointer
	While refactoring some other code in gdb/python/* I wanted to merge
	two code paths.  One path calls value_as_address, while the other
	calls unpack_pointer.

	I suspect calling value_as_address is the correct choice, but, while
	examining the code I noticed that value_as_address calls unpack_long
	rather than unpack_pointer.

	Under the hood, unpack_pointer does just call unpack_long so there's
	no real difference here, but it feels like value_as_address should
	call unpack_pointer.

	I've updated the code to use unpack_pointer, and changed a related
	comment to say that we call unpack_pointer.  I've also adjusted the
	header comment on value_as_address.  The existing header refers to
	some code that is now commented out.

	Rather than trying to describe the whole algorithm of
	value_as_address, which is already well commented within the function,
	I've just trimmed the comment on value_as_address to be a brief

	gdb/python: remove Py_TPFLAGS_BASETYPE from gdb.UnwindInfo
	It is not currently possible to directly create gdb.UnwindInfo
	instances, they need to be created by calling
	gdb.PendingFrame.create_unwind_info so that the newly created
	UnwindInfo can be linked to the pending frame.

	As such there's no tp_init method defined for UnwindInfo.

	A consequence of all this is that it doesn't really make sense to
	allow sub-classing of gdb.UnwindInfo.  Any sub-class can't call the
	parents __init__ method to correctly link up the PendingFrame
	object (there is no parent __init__ method).  And any instances that
	sub-classes UnwindInfo but doesn't call the parent __init__ is going
	to be invalid for use in GDB.

	This commit removes the Py_TPFLAGS_BASETYPE flag from the UnwindInfo
	class, which prevents the class being sub-classed.  Then I've added a

	gdb/python: add some additional methods to gdb.PendingFrame
	The gdb.Frame class has far more methods than gdb.PendingFrame.  Given
	that a PendingFrame hasn't yet been claimed by an unwinder, there is a
	limit to which methods we can add to it, but many of the methods that
	the Frame class has, the PendingFrame class could also support.

	In this commit I've added those methods to PendingFrame that I believe
	are safe.

	In terms of implementation: if I was starting from scratch then I
	would implement many of these (or most of these) as attributes rather
	than methods.  However, given both Frame and PendingFrame are just
	different representation of a frame, I think there is value in keeping
	the interface for the two classes the same.  For this reason
	everything here is a method -- that's what the Frame class does.

	The new methods I've added are:

	  - gdb.PendingFrame.is_valid: Return True if the pending frame
	    object is valid.

	  - gdb.PendingFrame.name: Return the name for the frame's function,
	    or None.

	  - gdb.PendingFrame.pc: Return the $pc register value for this
	    frame.

	  - gdb.PendingFrame.language: Return a string containing the
	    language for this frame, or None.

	  - gdb.PendingFrame.find_sal: Return a gdb.Symtab_and_line object
	    for the current location within the pending frame, or None.

	  - gdb.PendingFrame.block: Return a gdb.Block for the current
	    pending frame, or None.

	  - gdb.PendingFrame.function: Return a gdb.Symbol for the current
	    pending frame, or None.

	In every case I've just copied the implementation over from gdb.Frame
	and cleaned the code slightly e.g. NULL to nullptr.  Additionally each
	function required a small update to reflect the PendingFrame type, but
	that's pretty minor.

	There are tests for all the new methods.

	For more extensive testing, I added the following code to the file
	gdb/python/lib/command/unwinders.py:

	  from gdb.unwinder import Unwinder

	  class TestUnwinder(Unwinder):
	      def __init__(self):
	          super().__init__("XXX_TestUnwinder_XXX")

	      def __call__(self,pending_frame):
	          lang = pending_frame.language()
	          try:
	              block = pending_frame.block()
	              assert isinstance(block, gdb.Block)
	          except RuntimeError as rte:
	              assert str(rte) == "Cannot locate block for frame."
	          function = pending_frame.function()
	          arch = pending_frame.architecture()
	          assert arch is None or isinstance(arch, gdb.Architecture)
	          name = pending_frame.name()
	          assert name is None or isinstance(name, str)
	          valid = pending_frame.is_valid()
	          pc = pending_frame.pc()
	          sal = pending_frame.find_sal()
	          assert sal is None or isinstance(sal, gdb.Symtab_and_line)
	          return None

	  gdb.unwinder.register_unwinder(None, TestUnwinder())

	This registers a global unwinder that calls each of the new
	PendingFrame methods and checks the result is of an acceptable type.
	The unwinder never claims any frames though, so shouldn't change how
	GDB actually behaves.

	I then ran the testsuite.  There was only a single regression, a test
	that uses 'disable unwinder' and expects a single unwinder to be
	disabled -- the extra unwinder is now disabled too, which changes the
	test output.  So I'm reasonably confident that the new methods are not
	going to crash GDB.

	though the type of the exceptions is still ValueError in all cases.

	I started writing some tests for this change and immediately ran into
	a problem: GDB would crash.  It turns out that the PendingFrame
	objects are not being marked as invalid!

	In pyuw_sniffer where the pending frames are created, we make use of a
	scoped_restore to invalidate the pending frame objects.  However, this
	only restores the pending_frame_object::frame_info field to its
	previous value -- and it turns out we never actually give this field
	an initial value, it's left undefined.

	So, when the scoped_restore (called invalidate_frame) performs its
	cleanup, it actually restores the frame_info field to an undefined
	value.  If this undefined value is not nullptr then any future
	accesses to the PendingFrame object result in undefined behaviour and
	most likely, a crash.

	As part of this commit I now initialize the frame_info field, which
	ensures all the new tests now pass.

	gdb/python: make the gdb.unwinder.Unwinder class more robust
	This commit makes a few related changes to the gdb.unwinder.Unwinder
	class attributes:

	  1. The 'name' attribute is now a read-only attribute.  This prevents
	  user code from changing the name after registering the unwinder.  It
	  seems very unlikely that any user is actually trying to do this in
	  the wild, so I'm not very worried that this will upset anyone,

	  2. We now validate that the name is a string in the
	  Unwinder.__init__ method, and throw an error if this is not the
	  case.  Hopefully nobody was doing this in the wild.  This should
	  make it easier to ensure the 'info unwinder' command shows sane
	  output (how to display a non-string name for an unwinder?),

	  3. The 'enabled' attribute is now implemented with a getter and
	  setter.  In the setter we ensure that the new value is a boolean,
	  but the real important change is that we call
	  'gdb.invalidate_cached_frames()'.  This means that the backtrace
	  will be updated if a user manually disables an unwinder (rather than
	  calling the 'disable unwinder' command).  It is not unreasonable to
	  think that a user might register multiple unwinders (relating to
	  some project) and have one command that disables/enables all the
	  related unwinders.  This command might operate by poking the enabled
	  attribute of each unwinder object directly, after this commit, this
	  would now work correctly.

	There's tests for all the changes, and lots of documentation updates
	that both cover the new changes, but also further improve (I think)
	the general documentation for GDB's Unwinder API.

	RISC-V: PR28789, Reject R_RISCV_PCREL relocations with ABS symbol in PIC/PIE.
	The non-preemptible SHN_ABS symbol with a pc-relative relocation should be
	disallowed when generating shared object (pic and pie).  Generally, the
	following cases, which refer to pr25749, will cause a symbol be
	non-preemptible,

	* -pie, or -shared with -symbolic
	* STV_HIDDEN, STV_INTERNAL, STV_PROTECTED
	* Have dynamic symbol table, but without the symbol
	* VER_NDX_LOCAL

	However, PCREL_HI20/LO12 relocs are always bind locally when generating
	shared object, so not only the non-preemptible absolute symbol need to
	be disallowed, all absolute symbol references need but except that they
	are defined in linker script.  If we also disallow the absolute symbol
	in linker script, then the glibc-linux toolchain build failed, so regard
	them as pc-relative symbols, just like what x86 did.

	Maybe we should add this check for all pc-relative relocations, rather
	than just handle in R_RISCV_PCREL relocs.  Ideally, since the value of
	SHN_ABS symbol is a constant, only S - A relocations should be allowed
	in the shared object, so only BFD_RELOC_8/16/32/64 are allowed, which
	means R_RISCV_32/R_RISCV_64.

	Use the correct frame when evaluating a dynamic property
	The test case in this patch shows an unusual situation: an Ada array
	has a dynamic bound, but the bound comes from a frame that's referred
	to by the static link.  This frame is correctly found when evaluating
	the array variable itself, but is lost when evaluating the array's
	bounds.

	This patch fixes the problem by passing this frame through to
	value_at_lazy in the DWARF expression evaluator.

	gdb: move displaced_step_dump_bytes into gdbsupport (and rename)
	It was pointed out during review of another patch that the function
	displaced_step_dump_bytes really isn't specific to displaced stepping,
	and should really get a more generic name and move into gdbsupport/.

	This commit does just that.  The function is renamed to
	bytes_to_string and is moved into gdbsupport/common-utils.{cc,h}.  The
	function implementation doesn't really change. Much...

	... I have updated the function to take an array view, which makes it
	slightly easier to call in a couple of places where we already have a
	gdb::bytes_vector.  I've then added an inline wrapper to convert a raw
	pointer and length into an array view, which is used in places where
	we don't easily have a gdb::bytes_vector (or similar).

	Updated all users of displaced_step_dump_bytes.

	There should be no user visible changes after this commit.

	Finally, I ended up having to add an include of gdb_assert.h into
	array-view.h.  When I include array-view.h into common-utils.h I ran
	into build problems because array-view.h calls gdb_assert.

	gdb: more debug output for displaced stepping
	While investigating a displaced stepping issue I wanted an easy way to
	see what GDB thought the original instruction was, and what
	instruction GDB replaced that with when performing the displaced step.

	We do print out the address that is being stepped, so I can track down
	the original instruction, I just need to go find the information
	myself.

	And we do print out the bytes of the new instruction, so I can figure
	out what the replacement instruction was, but it's not really easy.

	Also, the code that prints the bytes of the replacement instruction
	only prints 4 bytes, which clearly isn't always going to be correct.

	In this commit I remove the existing code that prints the bytes of the
	replacement instruction, and add two new blocks of code to
	displaced_step_prepare_throw.  This new code prints the original
	instruction, and the replacement instruction.  In each case we print
	both the bytes that make up the instruction and the completely
	disassembled instruction.

	Here's an example of what the output looks like on x86-64 (this is
	with 'set debug displaced on').  The two interesting lines contain the
	strings 'original insn' and 'replacement insn':

	  (gdb) step

	  0x00007ffff7e402c0 in puts () from /lib64/libc.so.6
	  (gdb)

	One final note.  For many targets that support displaced stepping (in
	fact all targets except ARM) the replacement instruction is always a
	single instruction.  But on ARM the replacement could actually be a
	series of instructions.

	The debug code tries to handle this by disassembling the entire
	displaced stepping buffer.  Obviously this might actually print more
	than is necessary, but there's (currently) no easy way to know how
	many instructions to disassemble; that knowledge is all locked in the
	architecture specific code.  Still I don't think it really hurts, if
	someone is looking at this debug then hopefully they known what to
	expect.

	Obviously we can imagine schemes where the architecture specific
	displaced stepping code could communicate back how many bytes its
	replacement sequence was, and then our debug print code could use this
	to limit the disassembly.  But this seems like a lot of effort just to
	save printing a few additional instructions in some debug output.

	I'm not proposing to do anything about this issue for now.

	gdb/testsuite: allow "require" callbacks to provide a reason
	When an allow_* proc returns false, it can be a bit difficult what check
	failed exactly, if the procedure does multiple checks.  To make
	investigation easier, I propose to allow the "require" callbacks to be
	able to return a list of two elements: the zero/non-zero value, and a
	reason string.

	Use the new feature in allow_hipcc_tests to demonstrate it (it's also
	where I hit actually hit this inconvenience).  On my computer (where GDB
	is built with amd-dbgapi support but where I don't have a suitable GPU
	target), I get:

	    UNSUPPORTED: gdb.rocm/simple.exp: require failed: allow_hipcc_tests (no suitable amdgpu targets found)

	vs before:

	    UNSUPPORTED: gdb.rocm/simple.exp: require failed: allow_hipcc_tests

	[gdb/testsuite] Fix local-remote-host-native.exp for gdb.server tests
	When running test-case gdb.server/stop-reply-no-thread-multi.exp with
	host+target board local-remote-host-native, I run into a time-out:
	...
	(gdb) PASS: gdb.server/stop-reply-no-thread-multi.exp: target-non-stop=off: \
	  to_disable=: disconnect
	builtin_spawn /usr/bin/ssh -t -l vries 127.0.0.1 gdbserver --once \

	FAIL: gdb.server/stop-reply-no-thread-multi.exp: target-non-stop=off: \
	  to_disable=: set remote threads-packet off (timeout)
	...

	This is due to this line in ${board}_spawn:
	...
	    set board_info($board,fileid) $spawn_id
	...

	We have the following series of events:
	- gdb is spawned, setting fileid
	- a few gdb commands (set height etc) are send using fileid, arrive at gdb and
	  are successful
	- gdbserver is spawned, overwriting fileid
	- the next gdb command is sent using fileid, so it's send
	  to gdbserver instead of gdb, and we run into the timeout.

	There is some notion of current gdb, tracked in both gdb_spawn_id and fileid
	of the host board (see switch_gdb_spawn_id).  And because the host and target
	board are the same, spawning something on the target overwrites the fileid on
	host, and consequently the current gdb.

	Fix this by only setting fileid when spawning gdb.

	Tested on x86_64-linux.

	Now gdb.server/*.exp passes for host+target board local-remote-host-native,
	except for file-transfer.exp.

	gprofng: 30089 [display text] Invalid number of threads
	The real problem is that libcollector doesn't interpose thread_create@GLIBC_2.34
	We interpose a lot of libC functions (dlopen, fork, pthread_create, etc.).
	Some of these functions have versions. For example, dlopen@GLIBC_2.34,
	dlopen@GLIBC_2.17, dlopen@GLIBC_2.2.5, etc.
	We have to interpose each of the functions because we don't know
	which version of libC will be used during profiling.
	Historically, we have used three versions of scripts (mapfile.aarch64-Linux,
	mapfile.amd64-Linux, mapfile.intel-Linux).
	Three are not needed. One is enough

	The fixes below include:
	 - merged all version symbols into one version script.
	 - added new version symbols which are defined in latest versions of libC.
	 - removed unused defines and duplicated code.
	 - added the DCL_FUNC_VER macro to define the version symbols.

	Tested on x86_64 and aarch64 (OL8/OL9). No regression.

	displaced step: pass down target_waitstatus instead of gdb_signal
	This commit tweaks displaced_step_finish & friends to pass down a

	make displaced_step_buffers::finish handle
	TARGET_WAITKIND_THREAD_EXITED.  It also helps with the
	TARGET_WAITKIND_THREAD_CLONED patch later in that same series.

	It's also a bit more logical this way, as we don't have to pass down

	[gdb/testsuite] Skip do_self_tests on remote host
	In do_self_tests we try to find out the location of the gdb to debug, which
	will then be copied and renamed to xgdb.

	In principle, the host board specifies the location of GDB, on host.

	With remote host, we could upload that gdb from host to build/target, but we
	would miss the data directory (which is listed as the reason to skip
	do_self_tests for remote target).

	We could fix that by instead taking the gdb from build instead, but that
	wouldn't work with installed testing.

	It seems easier to just skip this on remote host.

	It could be made to work for the "[is_remote host] && [is_remote target]
	&& host == target" scenario (see board local-remote-host-native.exp), but
	that doesn't seem worth the effort.

	Use value_true in value_equal and value_less
	Both value_equal and value_less use value_as_long to check a

	LONGEST.  Instead, rewrite this in a form that works for any size

	Simplify binop_promote

	Simplify this code, unify the C and non-C (but not OpenCL, as I don't
	know how to test this) cases, and handle 128-bit integers as well.

	This still doesn't exactly follow C or C++ rules.  This could be

	This renames gdb_mpz::safe_export to export_bits, and adds a new flag
	to export a truncated value.  This is needed by value arithmetic.

	Avoid a copy in gdb_mpz::safe_export
	Currently, gdb_mpz::safe_export will always make a copy of *this.
	However, this copy isn't always needed.  This patch makes this code
	slightly more efficient, by avoiding the copy when possible.

	Add many operators to gdb_mpz

	(before) Space used: 28909568 (+0 for this command)
	(after)  Space used: 28884992 (+0 for this command)

	What this means, btw, is that in gdb there are not many symbols that
	are both mentioned in many CUs and that also require name
	canonicalization.  It's possible this would differ in other programs.

2023-03-27  Tom de Vries  <tdevries@suse.de>

	[gdb/testsuite] Add test-case gdb.dlang/dlang-start-2.exp
	For test-case gdb.dlang/dlang-start.exp, I run into:
	...
	UNSUPPORTED: gdb.dlang/dlang-start.exp: require failed: can_compile d
	...

	My distro has no support for gdc, but I'd like to have the test-case
	running and passing, so let's rewrite the test-case using dwarf assembly
	and add it alongside (rather than replacing it, because it's good to use
	actual compiler output if we have it available).

	My distro does have a package providing dmd, so let's mimic that debug info in
	the dwarf assembly.  This gives us:
	...
	(gdb) start ^M
	Temporary breakpoint 1 at 0x4004ab^M
	Starting program: dlang-start-2 ^M
	^M
	Temporary breakpoint 1, 0x00000000004004ab in _Dmain ()^M
	...

	The "_Dmain ()" should probably be "D main", I've filed PR30276 about that.

	Also add a "show language" to check that we automatically set the language
	correctly to D.

	Note that the dwarf assembly also describes main, otherwise the test-case
	doesn't function as regression test for commit 47fe57c9281 ("Fix "start" for
	D, Rust, etc").

	Tested on x86_64-linux.

	Use stdint types in coff internal_auxent
	long is a poor choice of type to store 32-bit values read from
	objects files by H_GET_32.  H_GET_32 doesn't sign extend so tests like
	that in gdb/coffread.c for "negative" values won't work if long is
	larger than 32 bits.  If long is 32-bit then code needs to be careful
	to not accidentally index negative array elements.  (I'd rather see a
	segfault on an unmapped 4G array index than silently reading bogus
	data.)  long is also a poor choice for x_sect.s_scnlen, which might
	have 64-bit values.  It's better to use unsigned exact width types to
	avoid surprises.

	I decided to change the field names too, which makes most of this

	---------------------
	../../../repos/binutils-gdb/gdb/thread.c:86: internal-error: inferior_thread: Assertion `current_thread_ != nullptr' failed.
	A problem internal to GDB has been detected,
	further debugging may prove unreliable.
	Quit this debugging session? (y or n)

	We also see failures across the testsuite if the tests get executed on a target
	that has native support for the pointer authentication feature. But
	gdb.base/break.exp and gdb.base/access-mem-running.exp are two examples of
	tests that run into errors and internal errors.

	This issue started after commit d88cb738e6a7a7179dfaff8af78d69250c852af1, which
	enabled more broad use of pointer authentication masks to remove non-address
	bits of pointers, but wasn't immediately detected because systems with native
	support for pointer authentication are not that common yet.

	The above crash happens because gdb is in the middle of handling an event,
	and do_target_wait_1 calls switch_to_inferior_no_thread, nullifying the
	current thread.  This means a call to inferior_thread () will assert, and
	attempting to call get_current_regcache () will also call inferior_thread (),
	resulting in an assertion as well.

	target_has_registers was one function that seemed useful for detecting these
	types of situation where we don't have a register cache. The problem with that
	is the inconsistent state of inferior_ptid, which is used by
	target_has_registers.

	Despite the call to switch_to_no_thread in switch_to_inferior_no_thread from
	do_target_wait_1 in the backtrace above clearing inferior_ptid, the call to
	ps_xfer_memory sets inferior_ptid momentarily before reading memory:

	static ps_err_e
	ps_xfer_memory (const struct ps_prochandle *ph, psaddr_t addr,
	                gdb_byte *buf, size_t len, int write)
	{
	  scoped_restore_current_inferior restore_inferior;
	  set_current_inferior (ph->thread->inf);

	  scoped_restore_current_program_space restore_current_progspace;
	  set_current_program_space (ph->thread->inf->pspace);

	  scoped_restore save_inferior_ptid = make_scoped_restore (&inferior_ptid);
	  inferior_ptid = ph->thread->ptid;

	  CORE_ADDR core_addr = ps_addr_to_core_addr (addr);

	  int ret;
	  if (write)
	    ret = target_write_memory (core_addr, buf, len);
	  else
	    ret = target_read_memory (core_addr, buf, len);
	  return (ret == 0 ? PS_OK : PS_ERR);
	}

	Maybe this shouldn't happen, or maybe it is just an unfortunate state to be
	in. But this prevents the use of target_has_registers to guard against the
	lack of registers, since, although current_thread_ is still nullptr,
	inferior_ptid is valid and is not null_ptid.

	There is another crash scenario after we kill a previously active inferior, in
	which case the gdbarch will still say we support pointer authentication but we
	will also have no current thread (inferior_thread () will assert etc).

	If the target has support for pointer authentication, gdb needs to use
	a couple (or 4, for bare-metal) mask registers to mask off some bits of
	pointers, and for that it needs to access the registers.

	At some points, like the one from the backtrace above, there is no active
	thread/current regcache because gdb is in the middle of doing event handling
	and switching between threads.

	Simon suggested the use of inferior_ptid to fetch the register cache, as
	opposed to relying on the current register cache.  Though we need to make sure
	inferior_ptid is valid (not null_ptid), I think this works nicely.

	With inferior_ptid, we can do safety checks along the way, making sure we have
	a thread to fetch a register cache from and checking if the thread is actually
	stopped or running.

	The following patch implements this idea with safety checks to make sure we
	don't run into assertions or errors.  If any of the checks fail, we fallback to
	using a default mask to remove non-address bits of a pointer.

	I discussed with Pedro the possibility of caching the mask register values
	(which are per-process and can change mid-execution), but there isn't a good
	spot to cache those values. Besides, the mask registers can change constantly
	for bare-metal debugging when switching between exception levels.

	In some cases, it is just not possible to get access to these mask registers,
	like the case where threads are running. In those cases, using a default mask
	to remove the non-address bits should be enough.

	This can happen when we let threads run in the background and then we attempt
	to access a memory address (now that gdb is capable of reading memory even
	with threads running).  Thus gdb will attempt to remove non-address bits
	of that memory access, will attempt to access registers, running into errors.

	Regression-tested on aarch64-linux Ubuntu 20.04.

	[gdb/testsuite] Fix unbalanced quotes in mi_expect_stop argument
	In proc mi_expect_stop there's a proc argument reason that's handled like so:
	...
	set r "reason=\"$reason\","
	...

	That's fine for say:
	...
	set reason "foo"
	...
	for which this evaluates to:
	...
	set r "reason=\"foo\","
	...

	But there are more complex uses, for instance:
	...
	set reason "breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal"
	...
	which evaluates to:
	...
	set r "\"breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal\""
	...

	Note how in this reason argument, the first two '\"' seems to form a pair
	surrounding ',disp=', which is not the case, which is confusing.

	Fix this by only adding the quotes in mi_expect_stop if the string doesn't
	already contain quotes, such that we have the more readable:
	...
	set reason "\"breakpoint-hit\",disp=\"keep\",bkptno=\"$decimal\""
	...

	Tested on x86_64-linux.

	[gdb/testsuite] Fix gdb.cp/m-static.exp regression on Ubuntu 20.04
	In commit 722c4596034 ("[gdb/testsuite] Fix gdb.cp/*.exp for remote host"), I
	needed to change ".*/" into "(.*/)?" in:
	...
	gdb_test "info variable everywhere" \
	    "File .*/m-static\[.\]h.*const int gnu_obj_4::everywhere;"
	...

	However, due to the fact that I got this output:
	...
	(gdb) info variable everywhere^M
	All variables matching regular expression "everywhere":^M
	^M
	File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static.h:^M
	8:      const int gnu_obj_4::everywhere;^M
	^M
	File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static1.cc:^M
	8:      const int gnu_obj_4::everywhere;^M
	...
	I decided to make the matching somewhat stricter, to make sure that the two
	matched lines were subsequent.

	The commit turned out to be more strict than intended, and caused a regression
	on Ubuntu 20.04, where the output was instead:
	...
	(gdb) info variable everywhere^M
	All variables matching regular expression "everywhere":^M
	^M
	File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static.h:^M
	8:      const int gnu_obj_4::everywhere;^M
	...

	At that point I realized I'm looking at a bug (filed as PR symtab/30265),
	which manifests on openSUSE Leap 15.4 for native and readnow, and on Ubuntu
	20.04 for readnow, but not for native.

	Before my commit, the test-case passed whether the bug manifested or not.

	After my commit, the test-case only passed when the bug manifested.

	Fix the test-case regression by reverting to the situation before the commit:
	pass whether the bug manifests or not.  We could add an xfail for the PR, but
	I'm expecting a fix soon, so that doesn't look worth the effort.

	Tested on x86_64-linux, both on openSUSE Leap 15.4 and Ubuntu 20.04, both with
	native and readnow.

	Simon reported that doing:

	- downloading to a location which is safe for parallel testing, by

	gdb/riscv: add systemtap support
	This commit is initial support for SystemTap for RISC-V Linux.  The
	following two tests exercise SystemTap functionality, and are showing
	many failures, which are all fixed by this commit:

	  gdb.cp/exceptprint.exp
	  gdb.base/stap-probe.exp

	One thing I wasn't sure about is if the SystemTap support should be
	Linux specific, or architecture specific.  For aarch64, arm, ia64, and
	ppc, the SystemTap support seems to libe in the ARCH-linux-tdep.c
	file, while for amd64, i386, and s390 the implementation lives in
	ARCH-tdep.c.  I have no idea which of these is the better choice -- or
	maybe both choices are correct in the right circumstances, and I'm
	just not aware of how to choose between them.

	Anyway, for this patch I selected riscv-tdep.c (though clearly, moving
	the changes to riscv-linux-tdep.c is trivial if anyone thinks that's a
	more appropriate location).

	The stap-probe.exp file tests immediate, register, and register
	indirect operands, all of which appear to be working fine with this
	commit.  The generic expression support doesn't appear to be
	architecture specific, so I'd expect that to work fine too.

	gdb: remove gdbarch_displaced_step_fixup_p
	The comment on the gdbarch_displaced_step_fixup gdbarch method
	indicates that this method is optional and that GDB will perform some
	default if this method is not supplied.  As such we define a predicate
	gdbarch_displaced_step_fixup_p.

	It may have been true at one point that the fixup method was optional,
	but it is no longer true.  If this method is not defined and GDB tries
	to complete a displaced step, then GDB is going to crash.

	Additionally the gdbarch_displaced_step_fixup_p predicate is not used
	anywhere in GDB.

	In this commit I have removed the gdbarch_displaced_step_fixup_p
	predicate, and I have updated the validation check for the
	gdbarch_displaced_step_fixup method; if the
	gdbarch_displaced_step_copy_insn method is defined then the fixup
	method must also be defined.

	I believe I've manually checked all the current places where
	gdbarch_displaced_step_copy_insn is defined and they all also define
	the fixup method, so this change should cause no problems for anyone.

	There should be no user visible changes after this commit.

	gdb: make "maintenance info line-table" show relocated addresses again
	Commit 1acc9dca423f ("Change linetables to be objfile-independent")
	changed "maintenance info line-table" to print unrelocated addresses
	instead of relocated.  This breaks a few tests on systems where that
	matters.  The ones I see are:

	    Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/consecutive.exp ...
	    FAIL: gdb.base/consecutive.exp: stopped at bp, 2nd instr (missing hex prefix)
	    Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/async.exp ...
	    FAIL: gdb.base/async.exp: stepi&
	    FAIL: gdb.base/async.exp: nexti&
	    FAIL: gdb.base/async.exp: finish&

	These tests run "maintenance info line-table" to record the address of
	some lines, and then use these addresses in expected patterns.  It
	therefore expects these addresses to match the runtime addresses,
	therefore the relocated addresses.

	Add back the relocated addresses, next to the unrelocated addresses,
	like so:

	    INDEX  LINE   REL-ADDRESS        UNREL-ADDRESS      IS-STMT PROLOGUE-END
	    0      6      0x0000555555555119 0x0000000000001119 Y
	    1      7      0x000055555555511d 0x000000000000111d Y
	    2      8      0x0000555555555123 0x0000000000001123 Y
	    3      END    0x0000555555555125 0x0000000000001125 Y

	The unrelocated addresses can always be useful trying to map this
	information with a DWARF info dump.

	Adjust the is_stmt_addresses proc in the testsuite to match the new
	output.

	   PowerPC: fix for gdb.reverse/finish-precsave.exp and gdb.reverse/finish-reverse.exp

	   PPC64 multiple entry points, a normal entry point and an alternate entry
	   point.  The alternate entry point is to setup the Table of Contents (TOC)
	   register before continuing at the normal entry point.  When the TOC is
	   already valid, the normal entry point is used, this is typically the case.
	   The alternate entry point is typically referred to as the global entry
	   point (GEP) in IBM.  The normal entry point is typically referred to as
	   the local entry point (LEP).
	     .....

	Is causing regression failures on on PowerPC platforms.  The regression
	failures are in tests:

	  gdb.reverse/finish-precsave.exp
	  gdb.btrace/tailcall.exp
	  gdb.mi/mi-reverse.exp
	  gdb.btrace/step.exp
	  gdb.reverse/until-precsave.exp
	  gdb.reverse/finish-reverse.exp
	  gdb.btrace/tailcall-only.exp

	The issue is in gdb/infcmd.c, function finish_command.  The value of the
	two new variables ALT_ENTRY_POINT and ENTRY_POINT are being initializezed
	to SAL.PC.  However, SAL has just been declared.  The value of SAL.PC is
	zero at this point.  The intialization of ALT_ENTRY_POINT and ENTRY_POINT
	needs to be after the initialization of SAL.

	This patch moves the initialization of ALT_ENTRY_POINT and ENTRY_POINT
	variables to fix the regression failures.

	The patch has been tested on Power10 and on X86.

	[gdb/testsuite] Handle remotedir in remote_upload
	Dejagnu's remotedir implementation has support in remote_exec and
	remote_download, but not remote_upload.

	Consider the following scenario:
	- downloading an executable to target,
	- running it,
	- uploading a file produced by the executable
	while assuming remote target user remote-target with homedir
	/home/remote-target and remotedir set to /home/remote-target/tmp.

	Concretely, it looks like this:
	...
	 # binfile == "$outputs/gdb.abc/a.out"
	 set target_binfile [remote_download target $binfile]
	 # target_binfile == "/home/remote-target/tmp/a.out"
	 remote_exec target $target_binfile
	 # Running $target_binfile produced /home/remote-target/tmp/result.txt.
	 set result [remote_upload target /home/remote-target/tmp/result.txt \
	                 $outputs/gdb.abc/result.txt]
	 # result == $outputs/gdb.abc/result.txt.
	...

	Add a remote_upload implementation that also handles remotedir in lib/gdb.exp,
	overriding dejagnu's remote_upload, such that we can simplify the
	remote_upload call to:
	...
	 set result [remote_upload target result.txt $outputs/gdb.abc/result.txt]
	...

	Tested on x86_64-linux.

	gdb: fix crash during command completion
	In some cases GDB will fail when attempting to complete a command that
	involves a rust symbol, the failure can manifest as a crash.

	The problem is caused by the completion_match_for_lcd object being
	left containing invalid data during calls to cp_symbol_name_matches_1.

	The first question to address is why we are calling a C++ support
	function when handling a rust symbol.  That's due to GDB's auto
	language detection for msymbols, in some cases GDB can't tell if a
	symbol is a rust symbol, or a C++ symbol.

	The test application contains symbols for functions which are
	statically linked in from various rust support libraries.  There's no
	DWARF for these symbols, so all GDB has is the msymbols built from the
	ELF symbol table.

	Here's the problematic symbol that leads to our crash:

	    mangled: _ZN4core3str21_$LT$impl$u20$str$GT$5parse17h5111d2d6a50d22bdE
	  demangled: core::str::<impl str>::parse

	As an msymbol this is initially created with language auto, then GDB
	eventually calls symbol_find_demangled_name, which loops over all
	languages calling language_defn::sniff_from_mangled_name, the first
	language that can demangle the symbol gets assigned as the language
	for that symbol.

	Unfortunately, there's overlap in the mangled symbol names,
	some (legacy) rust symbols can be demangled as both rust and C++, see
	cplus_demangle in libiberty/cplus-dem.c where this is mentioned.

	And so, because we check the C++ language before we check for rust,
	then the msymbol is (incorrectly) given the C++ language.

	Now it's true that is some cases we might be able to figure out that a
	demangled symbol is not actually a valid C++ symbol, for example, in
	our case, the construct '::<impl str>::' is not, I believe, valid in a
	C++ symbol, we could look for ':<' and '>:' and refuse to accept this
	as a C++ symbol.

	However, I'm not sure it is always possible to tell that a demangled
	symbol is rust or C++, so, I think, we have to accept that some times
	we will get this language detection wrong.

	If we accept that we can't fix the symbol language detection 100% of
	the time, then we should make sure that GDB doesn't crash when it gets
	the language wrong, that is what this commit addresses.

	In our test case the user tries to complete a symbol name like this:

	  (gdb) complete break pars

	This results in GDB trying to find all symbols that match 'pars',
	eventually we consider our problematic symbol, and we end up with a
	call stack that looks like this:

	  #0  0x0000000000f3c6bd in strncmp_iw_with_mode
	  #1  0x0000000000706d8d in cp_symbol_name_matches_1
	  #2  0x0000000000706fa4 in cp_symbol_name_matches
	  #3  0x0000000000df3c45 in compare_symbol_name
	  #4  0x0000000000df3c91 in completion_list_add_name
	  #5  0x0000000000df3f1d in completion_list_add_msymbol
	  #6  0x0000000000df4c94 in default_collect_symbol_completion_matches_break_on
	  #7  0x0000000000658c08 in language_defn::collect_symbol_completion_matches
	  #8  0x0000000000df54c9 in collect_symbol_completion_matches
	  #9  0x00000000009d98fb in linespec_complete_function
	  #10 0x00000000009d99f0 in complete_linespec_component
	  #11 0x00000000009da200 in linespec_complete
	  #12 0x00000000006e4132 in complete_address_and_linespec_locations
	  #13 0x00000000006e4ac3 in location_completer

	In cp_symbol_name_matches_1 we enter a loop, this loop repeatedly
	tries to match the demangled problematic symbol name against the user
	supplied text ('pars').  Each time around the loop another component
	of the symbol name is stripped off, thus, we check 'pars' against
	these options:

	  core::str::<impl str>::parse
	  str::<impl str>::parse
	  <impl str>::parse
	  parse

	As soon as we get a match the cp_symbol_name_matches_1 exits its loop
	and returns.  In our case, when we're looking for 'pars', the match
	occurs on the last iteration of the loop, when we are comparing to
	'parse'.

	Now the problem here is that cp_symbol_name_matches_1 uses the
	strncmp_iw_with_mode, and inside strncmp_iw_with_mode we allow for
	skipping over template parameters.  This allows GDB to match the
	symbol name 'foo<int>(int,int)' if the user supplies 'foo(int,'.
	Inside strncmp_iw_with_mode GDB will record any template arguments
	that it has skipped over inside the completion_match_for_lcd object
	that is passed in as an argument.

	And so, when GDB tries to match against '<impl str>::parse', the first
	thing it sees is '<impl str>', GDB assumes this is a template argument
	and records this as a skipped region within the
	completion_match_for_lcd object.  After '<impl str>' GDB sees a ':'
	character, which doesn't match with the 'pars' the user supplied, so
	strncmp_iw_with_mode returns a value indicating a non-match.  GDB then
	removes the '<impl str>' component from the symbol name and tries
	again, this time comparing to 'parse', which does match.

	Having found a match, then in cp_symbol_name_matches_1 we record the
	match string, and the full symbol name within the
	completion_match_result object, and return.

	The problem here is that the skipped region, the '<impl str>' that we
	recorded in the penultimate loop iteration was never discarded, its
	still there in our returned result.

	If we look at what the pointers held in the completion_match_result
	that cp_symbol_name_matches_1 returns, this is what we see:

	  core::str::<impl str>::parse
	  |          \________/  |
	  |               |      '--- completion match string
	  |               '---skip range
	  '--- full symbol name

	When GDB calls completion_match_for_lcd::finish, GDB tries to create a
	string using the completion match string (parse), but excluding the
	skip range, as the stored skip range is before the start of the
	completion match string, then GDB tries to do some weird string
	creation, which will cause GDB to crash.

	The reason we don't often see this problem in C++ is that for C++
	symbols there is always some non-template text before the template
	argument.  This non-template text means GDB is likely to either match
	the symbol, or reject the symbol without storing a skip range.

	However, notice, I did say, we don't often see this problem.  Once I
	understood the issue, I was able to reproduce the crash using a pure
	C++ example:

	  template<typename S>
	  struct foo
	  {
	    template<typename T>
	    foo (int p1, T a)
	    {
	      s = 0;
	    }

	    S s;
	  };

	  int
	  main ()
	  {
	    foo<int> obj (2.3, 0);
	    return 0;
	  }

	Then in GDB:

	  (gdb) complete break foo(int

	The problem here is that the C++ symbol for the constructor looks like
	this:

	  foo<int>::foo<double>(int, double)

	When GDB enters cp_symbol_name_matches_1 the symbols it examines are:

	  foo<int>::foo<double>(int, double)
	  foo<double>(int, double)

	The first iteration of the loop will match the 'foo', then add the
	'<int>' template argument will be added as a skip range.  When GDB
	find the ':' after the '<int>' the first iteration of the loop fails
	to match, GDB removes the 'foo<int>::' component, and starts the
	second iteration of the loop.

	Again, GDB matches the 'foo', and now adds '<double>' as a skip
	region.  After that the '(int' successfully matches, and so the second
	iteration of the loop succeeds, but, once again we left the '<int>' in
	place as a skip region, even though this occurs before the start of
	our match string, and this will cause GDB to crash.

	This problem was reported to the mailing list, and a solution
	discussed in this thread:

	  https://sourceware.org/pipermail/gdb-patches/2023-January/195166.html

	The solution proposed here is similar to one proposed by the original
	bug reported, but implemented in a different location within GDB.
	Instead of placing the fix in strncmp_iw_with_mode, I place the fix in
	cp_symbol_name_matches_1.  I believe this is a better location as it
	is this function that implements the loop, and it is this loop, which
	repeatedly calls strncmp_iw_with_mode, that should be resetting the
	result object state (I believe).

	What I have done is add an assert to strncmp_iw_with_mode that the
	incoming result object is empty.

	I've also added some other asserts in related code, in
	completion_match_for_lcd::mark_ignored_range, I make some basic
	assertions about the incoming range pointers, and in
	completion_match_for_lcd::finish I also make some assertions about how
	the skip ranges relate to the match pointer.

	There's two new tests.  The original rust example that was used in the
	initial bug report, and a C++ test.  The rust example depends on which
	symbols are pulled in from the rust libraries, so it is possible that,
	at some future date, the problematic symbol will disappear from this
	test program.  The C++ test should be more reliable, as this only
	depends on symbols from within the C++ source code.

	Since I originally posted this patch to the mailing list, the
	following patch has been merged:

	  commit 6e7eef72164c00d6a5a7b0bce9fa01f5481f33cb
	  Date:   Sun Mar 19 09:13:10 2023 -0600

	      Use rust_demangle to fix a crash

	This solves the problem of a rust symbol ending up in the C++ specific
	code by changing the order languages are sorted.  However, this new
	commit doesn't address the issue in the C++ code which was fixed with
	this commit.

	Given that the C++ issue is real, and has a reproducer, I'm still
	going to merge this fix.  I've left the discussion of rust in this
	commit message as I originally wrote it, but it should be read within
	the context of GDB prior to commit 6e7eef72164c00d6a5a7.

	x86: drop identifier_chars[]
	It tries to resemble what's underlying is_part_of_name(), but doesn't
	quite achieve that: '$' for example is unconditionally marked as part of
	symbol names, but was included as identifier char for Intel syntax only.
	Note that i386_att_operand() checks for the immediate prefix first, so
	the wider coverage by starts_memory_operand() is has no real effect
	there, but it does matter for something like

		mov	%fs:$dollar, %eax

	which previously wasn't accepted (but which clearly is a memory
	reference - there's no point in forcing people to parenthesize the
	symbol name). Similarly including '%' as an identfier for Intel syntax
	had no real significance to the rest of the assembler. If '%' was to be
	valid in (unquoted) symbol names, LEX_PCT would need to be defined.

	Note further that this also addresses the latent issue of a sub-target
	defining LEX_AT or LEX_QM to zero: That would make '@' and/or '?' no
	valid part of symbol names, but would have included them in what
	is_identifier_char() considers a valid part of a name. (There's a minor
	related issue which is actually being eliminated: te-interix.h allows
	'@' only in the middle of symbol names, yet starts_memory_operand()
	specifically looks at the first character of [possibly] a symbol name.)

	In parse_real_register() there's no point also checking is_name_ender()
	as at this point no character is marked solely LEX_END_NAME by any sub-
	target. Checking is_name_beginner() is also pointless as the hash lookup
	will fail anyway for a zero-length name.

	While touching the check in parse_real_register() also drop the
	"allow_naked_reg" part of the condition: This has only led to
	inconsistent error messages.

	x86/AT&T: restrict recognition of the "absolute branch" prefix character
	While in principle merely rejecting this for .insn would be sufficient
	for the purposes there, be more generic and reject it for anything that
	isn't going to be a branch: All elements of same-mnemonic template
	groups either are branches, or are not, and the few cases possibly
	requiring a 2nd parsing pass aren't affected either. This then also
	improves diagnostics for misuses like

	x86: drop "shimm" special case template expansions
	With VexVVVV only being boolean, the SSE shift-by-immediate instructions

	x86: VexVVVV is now merely a boolean
	With the SDM long having dropped the NDS/NDD/DDS concept of identifying
	encoding variants, we can finally do away with this concept as well. Of
	the few consumers of the attribute, only an assertion was still checking
	for a particular value, which we don't really need to retain.

	When touching lines anyway, modernize other aspects as well. This often
	improves similarity to adjacent lines.

2023-03-20  Jan Beulich  <jbeulich@suse.com>

	x86: re-work build_modrm_byte()'s register assignment
	The function has accumulated a number of special cases for no real
	reason. Some were necessary because insn attributes (SwapSources in
	particular) weren't suitably utilized instead. Note that the addition of
	SwapSources actually increases consistency among the templates: Like
	others which already have the attribute, these are all insns where the
	VEX.VVVV-encoded register comes first (or last when looking at the SDM).

	Note that the vexvvvv attribute now has merely boolean meaning anymore,
	in line with the SDM long having dropped the NDS/NDD/DDS concept of
	identifying encoding variants. The fallout will be taken care of
	subsequently, though, to not further clutter the change here.

	As to the TILEZERO special case: If more instructions like this
	appeared, a new attribute would likely be the way to go. But as long as
	it's only a single insn, going from the mnemonic is cheaper.

	Use rust_demangle to fix a crash
	PR rust/30211 points out a crash caused by a particular completion.
	This turns out to happen because a Rust minsym winds up in a
	C++-specific path in strncmp_iw_with_mode, which ultimately causes the
	completer to pass invalid arguments to string::append.

	This patch fixes the bug by reordering the language constants so that
	Rust comes before C++, and then using rust_demangle.  This ensures
	that minsyms are correctly marked as "Rust", avoiding this code and
	thus the crash.

	gdb: don't use the global thread-id in the saved breakpoints file
	I noticed that breakpoint::print_recreate_thread was printing the
	global thread-id.  This function is used to implement the 'save
	breakpoints' command, and should be writing out suitable CLI commands
	for recreating the current breakpoints.  The CLI does not use global
	thread-ids, but instead uses the inferior specific thread-ids,
	e.g. "2.1".

	After some discussion on the mailing list it was suggested that the
	most consistent solution would be for the saved breakpoints file to
	always contain the inferior-qualified thread-id, so the file would
	include "thread 1.1" instead of just "thread 1", even when there is
	only a single inferior.

	So, this commit adds print_full_thread_id, which is just like the
	existing print_thread_id, only it always prints the inferior-qualified
	thread-id.

	I then update the existing print_thread_id to make use of this new
	function, and finally, I update  breakpoint::print_recreate_thread to
	also use this new function.

	There's a multi-inferior test that confirms the saved breakpoints file
	correctly includes the fully-qualified thread-id, and I've also
	updated the single inferior test gdb.base/save-bp.exp to have it
	validate that the saved breakpoints file includes the
	inferior-qualified thread-id, even for this single inferior case.

	Use builtin type when appropriate
	There are a few spots that check whether a type is objfile-owned, and
	then choose either the objfile- or arch-specific builtin type.  I
	don't think there is a need to do this any more (if there ever was),
	because it is ok for an objfile-allocated type to refer to an
	arch-allocated type.

	Fix line table regression
	Simon pointed out a line table regression, and after a couple of false
	starts, I was able to reproduce it by hand using his instructions.

	The bug is that most of the code in do_mixed_source_and_assembly uses
	unrelocated addresses, but one spot does:

	  pc = low;

	... after the text offset has been removed.

	This patch fixes the problem by introducing a new type to represent
	unrelocated addresses in the line table.  This prevents this sort of
	bug to some degree (it's still possible to manipulate a CORE_ADDR in a
	bad way, this is unavoidable).

	However, this did let the compiler flag a few spots in that function,
	and now it's not possible to compare an unrelocated address from a
	line table with an ordinary CORE_ADDR.

	Regression tested on x86-64 Fedora 36, though note this setup never
	reproduced the bug in the first place.  I also tested it by hand on
	the disasm-optim test program.

	gdb: introduce bp_loc_tracepoint
	Since commit cb1e4e32c2d9 ("catch catch/throw/rethrow", breakpoint ->
	catchpoint), this simple tracing scenario does not work:

	    $ gdb/gdb -nx -q --data-directory=gdb/data-directory ./test
	    Reading symbols from ./test...
	    (gdb) tar rem :1234
	    Remote debugging using :1234
	    Reading symbols from /lib64/ld-linux-x86-64.so.2...
	    (No debugging symbols found in /lib64/ld-linux-x86-64.so.2)
	    0x00007ffff7fe5730 in ?? () from /lib64/ld-linux-x86-64.so.2
	    (gdb) trace do_something
	    Tracepoint 1 at 0x555555555144: file test.c, line 5.
	    (gdb) tstart
	    (gdb) continue
	    Continuing.
	    Target returns error code '01'.

	The root cause is that the bp_location::nserted flag does not transfer
	anymore from an old bp_location to the new matching one.  When a shared
	library gets loaded, GDB computes new breakpoint locations for each
	breakpoint in update_breakpoint_locations.  The new locations are in the
	breakpoint::loc chain, while the old locations are still in the
	bp_locations global vector.  Later, update_global_location_list is
	called.  It tries to map old locations to new locations, and if
	necessary transfer some properties, like the inserted flag.

	Since commit cb1e4e32c2d9, the inserted flag isn't transferred for
	locations of tracepoints.  This is because bl_address_is_meaningful used
	to be implemented like this:

	    static int
	    breakpoint_address_is_meaningful (struct breakpoint *bpt)
	    {
	      enum bptype type = bpt->type;

	      return (type != bp_watchpoint && type != bp_catchpoint);
	    }

	and was changed to this:

	    static bool
	    bl_address_is_meaningful (bp_location *loc)
	    {
	      return loc->loc_type != bp_loc_other;
	    }

	Because locations for tracepoints have the bp_loc_other type,
	bl_address_is_meaningful started to return false for them, where it
	returned true before.  This made update_global_location_list skip the
	part where it calls swap_insertion.

	I think this can be solved by introduced a new bp_loc_tracepoint
	bp_loc_type.

	I don't know if it's accurate, but my understanding is that bp_loc_type
	describes roughly "how do we ask the target to insert that location".
	bp_loc_software_breakpoint are inserted using
	target_ops::insert_breakpoint_location.  bp_loc_hardware_breakpoint are
	inserted using target_ops::insert_hw_breakpoint.
	bp_loc_software_watchpoint and bp_loc_hardware_watchpoint are inserted
	using target_ops::insert_watchpoint.  For all these, the address is
	meaningful, as we ask the target to insert the point at a specific
	address.  bp_loc_other is a catch-all for "the rest", in practice for
	catchpoints that don't have a specific address (hence why
	bl_address_is_meaningful returns false for them).  For instance,
	inserting a signal catchpoint is done by asking the target to report
	that specific signal.  GDB doesn't associate an address to that.

	But tracepoints do have a meaningful address to thems, so they can't be
	bp_loc_other, with that logic.  They also can't be
	bp_loc_software_breakpoint, because we don't want GDB to insert
	breakpoints for them (even though they might be implemented using
	software breakpoints by the remote side).  So, the new bp_loc_tracepoint
	type describes that the way to insert these locations is with
	target_ops::download_tracepoint.  It makes bl_address_is_meaningful
	return true for them.  And they'll be ignored by insert_bp_location and
	GDB won't try to insert a memory breakpoint for them.

	With this, I see a few instances of 'Target returns error code: 01'
	disappearing from gdb.log, and the results of gdb.trace/*.exp improve a
	little bit:

	    -# of expected passes       3765
	    +# of expected passes       3781
	    -# of unexpected failures   518
	    +# of unexpected failures   498

	Things remain quite broken in that area though.

	PowerPC: fix for gdb.reverse/finish-precsave.exp and gdb.reverse/finish-reverse.exp
	PPC64 multiple entry points, a normal entry point and an alternate entry
	point.  The alternate entry point is to setup the Table of Contents (TOC)
	register before continuing at the normal entry point.  When the TOC is
	already valid, the normal entry point is used, this is typically the case.
	The alternate entry point is typically referred to as the global entry
	point (GEP) in IBM.  The normal entry point is typically referred to as
	the local entry point (LEP).

	When GDB is executing the finish command in reverse, the function
	finish_backward currently sets the break point at the alternate entry point.
	This issue is if the function, when executing in the forward direction,
	entered the function via the normal entry point, execution in the reverse
	direction will never sees the break point at the alternate entry point.  In
	this case, the reverse execution continues until the next break point is
	encountered thus stopping at the wrong place.

	This patch adds a new address to struct execution_control_state to hold the
	address of the alternate entry point (GEP).  The finish_backwards function
	is updated, if the stopping point is between the normal entry point (LEP)
	and the end of the function, a breakpoint is set at the normal entry point.
	If the stopping point is between the entry points, a breakpoint is set at
	the alternate entry point.  This ensures that GDB will always stop at the
	normal entry point.  If the function did enter via the alternate entry
	point, GDB will detect that and continue to execute backwards in the
	function until the alternate entry point is reached.

	The patch fixes the behavior of the reverse-finish command on PowerPC to
	match the behavior of the command on other platforms, specifically X86.
	The patch does not change the behavior of the command on X86.

	A new test is added to verify the reverse-finish command on PowerPC
	correctly stops at the instruction where the function call is made.

	The patch fixes 11 regression errors in test gdb.reverse/finish-precsave.exp
	and 11 regression errors in test gdb.reverse/finish-reverse.exp.

	The patch has been tested on Power 10 and X86 processor with no new
	regression failures.

	the new repeat_cmd_until procedure with the command set to "step" and an
	optional CURRENT string.  The default CURRENT string is set to "\}" to work
	with the existing uses of procedure gdb_step_until.

	gdb/doc: extended documentation for inferior function calls
	I noticed that the documentation for inferior function calls doesn't
	say much about what happens if/when an inferior function call is
	interrupted, i.e. it doesn't describe what the dummy frame looks like
	on the stack, or how GDB behaves when the inferior is continued and
	reaches the dummy frame.

	This commit aims to add some of this missing information.

	Re: Add --enable-linker-version option
	The recently-added ld-version*.d tests expect
	.*GNU ld \(GNU Binutils\) 2.*
	in the .comment section.

	However, when buidling --with-pkgversion=XXX, we get
	GNU ld (XXX) 2.[...]
	instead, leading to a spurious FAIL.

	This small patch replaces "GNU Binutils" with ".*" instead.

	I inspected other testcases to see if we already had similar
	occurrences but I couldn't see any, so I hope this fix is OK for the
	purpose?

	Thanks,

	gdb/doc: spring clean the Python unwinders documentation
	The documentation for the Python Unwinders API could do with some
	improvement.  The 'Unwinder Skeleton Code' has an error: it says
	'unwinders' when it should say 'unwinder' in one case.

	Additionally, by placing the 'Unwinder Skeleton Code' before the
	section 'Registering an Unwinder' we have skipping including the
	registration line in the skeleton code.  But this is confusion for
	users (I think) as the skeleton code is almost complete, except for
	one missing line which the user has to figure out for themselves.  By
	reordering the sections, it is now obvious that the registration
	should be included in the skeleton code, and the example is therefore
	almost complete.

	Additionally, in the example skeleton code the way in which the
	frame-id was being built (using the current stack point and program
	counter is (a) not correct, and (b) counter to what is laid out in the
	'Unwinder Input' section when describing building a frame-id.

	I've removed the incorrect code and replaced it with more generic
	comments indicating what needs to be done.  As the actual actions that
	need to be performed are both architecture specific, and dependent on
	the function being unwound, it's almost impossible to include more
	exact code here, but I think what I'm proposing is less misleading
	than what we had before.

	I've also added more cross references.

	gdb: add gdbarch::displaced_step_buffer_length
	The gdbarch::max_insn_length field is used mostly to support displaced
	stepping; it controls the size of the buffers allocated for the
	displaced-step instruction, and is also used when first copying the
	instruction, and later, when fixing up the instruction, in order to
	read in and parse the instruction being stepped.

	However, it has started to be used in other places in GDB, for
	example, it's used in the Python disassembler API, and it is used on
	amd64 as part of branch-tracing instruction classification.

	The problem is that the value assigned to max_insn_length is not
	always the maximum instruction length, but sometimes is a multiple of
	that length, as required to support displaced stepping, see rs600,
	ARM, and AArch64 for examples of this.

	It seems to me that we are overloading the meaning of the
	max_insn_length field, and I think that could potentially lead to
	confusion.

	I propose that we add a new gdbarch field,
	gdbarch::displaced_step_buffer_length, this new field will do
	exactly what it says on the tin; represent the required displaced step
	buffer size.  The max_insn_length field can then do exactly what it
	claims to do; represent the maximum length of a single instruction.

	As some architectures (e.g. i386, and amd64) only require their
	displaced step buffers to be a single instruction in size, I propose
	that the default for displaced_step_buffer_length will be the
	value of max_insn_length.  Architectures than need more buffer space
	can then override this default as needed.

	I've updated all architectures to setup the new field if appropriate,
	and I've audited all calls to gdbarch_max_insn_length and switched to
	gdbarch_displaced_step_buffer_length where appropriate.

	There should be no user visible changes after this commit.

	gdbarch: make invalid=True the default for all Components
	This commit switches the default value for the 'invalid' field from
	False to True.  All components that previous set the invalid field to
	True explicitly have had the field removed.

	I think that True is a good choice for the default, this means that we
	now get the validity checks by default, and if anyone adds a new
	Component they need to make a choice to add an 'invalid=False' line
	and disable the validation.

	The flip side of this is that 'invalid=False' seems to be far more
	common than 'invalid=True'.  But I don't see a huge problem with this,
	we shouldn't be aiming to reduce our typing, rather we should choose
	based on which is least likely to introduce bugs.  I think assuming
	that we should do a validity check will achieve that.

	Some additional components need to have an 'invalid=False' line added
	to their definition, these are components that have a predefault
	value, which is sufficient; the tdep code doesn't need to replace this
	value if it doesn't want to.

	Without adding the 'invalid=False' these components would be
	considered to be invalid if they have not changed from their
	predefault value -- but the predefault is fine.

	There's no change in the generated code after this commit, so there
	will be no user visible changes after this commit.

	gdbarch: remove some unneeded predefault="0" from gdbarch_components.py
	I noticed that there are a bunch of 'predefault="0"' lines in
	gdbarch_components.py, and that some (just some, not all) of these are
	not needed.

	The gdbarch is already zero initialized, but these lines seem to
	exists so that we can know when to compare against "0" and when to
	compare against "NULL".  At least, this seems to be useful in some
	places in the generated code.

	Specifically, if we remove the predefault="0" line from the
	max_insn_length component then we end up generating a line like:

	  gdb_assert (gdbarch->max_insn_length != NULL);

	which doesn't compile as we compare a ULONGEST to NULL.

	In this commit I remove all the predefault="0" lines that I claim are
	obviously not needed.  These are lines for components that are not
	Values (i.e. the component holds a function pointer anyway), or for
	Value components that hold a pointer type, in which case using NULL is
	fine.

	The only changes after this commit are some fields that have nullptr
	as their initial value, and gcore_bfd_target now compares to NULL not
	0 in gdbarch_gcore_bfd_target_p, which, given the field is of type
	'const char *', seems like an improvement.

	gdbarch: improve generation of validation in gdbarch getters
	We currently generate some validation code within the gdbarch getter
	methods.

	This commit adjusts the algorithm used to generate this validation
	slightly to make the gdbarch.py code (I think) clearer; there's no
	significant changes to what is generated.

	The validation algorithm for gdbarch values is now:

	  - If the Value has an 'invalid' field that is a string, use that for
	    validation,

	  - If the Value has its 'predicate' field set to true, then check the
	    predicate returns true, this ensures the predicate has been
	    called,

	  - If the Value has its 'invalid' field set to True, or the Value has
	    'postdefault' field, then check the fields has changed from its
	    initial value,

	  - Otherwise no validation is performed.

	The only changes after this commit are:

	  - Some comments change slightly, and

	  - For 'gcore_bfd_target' and 'max_insn_length' we now validate by
	    calling the predicate rather than checking the field value
	    directly, the underlying check being performed is unchanged
	    though.

	There should be no user visible changes after this commit.

	gdbarch: use predefault for more value components within gdbarch

	  bfloat16_format
	  half_format
	  float_format
	  double_format
	  long_double_format
	  so_ops

	All use a postdefault but no predefault to set the default value for
	the component.

	As the postdefault values for these components are all constant
	pointers that don't depend on other fields within the gdbarch, then I
	don't see any reason why we couldn't use a predefault instead.

	So lets do that.

	gdb/gdbarch: remove the 'invalid=None' state from gdbarch_components.py
	This commit ensures that the 'invalid' property of all components is
	either True, False, or a string.

	Additionally, this commit allows a component to have both a predicate
	and for the 'invalid' property to be a string.

	Removing the option for 'invalid' to be None allows us to simplify the
	algorithms in gdbarch.py a little.

	Allowing a component to have both a predicate and an 'invalid' string
	means that we can validate the value that a tdep sets into a field,
	but also allow a predicate to ensure that the field has changed from
	the default.

	This functionality isn't going to be used in this series, but I have
	tested it locally and believe that it would work, and this might make
	it easier for others to add new components in the future.

	In gdbarch_types.py, I've updated the type annotations to show that
	the 'invalid' field should not be None, and I've changed the default
	for this field from None to False.

	The change to using False as the default is temporary.  Later in this
	series I'm going to change the default to True, but we need more fixes
	before that can be done.

	Additionally, in gdbarch_types.py I've removed an assert from
	Component.get_predicate.  This assert ensured that we didn't have the
	predicate field set to True and the invalid field set to a string.
	However, no component currently uses this configuration, and after
	this commit, that combination is now supported, so the assert can be
	removed.

	As a consequence of the gdbarch_types.py changes we see some
	additional comments generated in gdbarch.c about verification being
	skipped due to the invalid field being False.  This comment is inline
	with plenty of other getters that also have a similar comment.  Plenty
	of the getters do have validation, so I think it is reasonable to have
	a comment noting that the validation has been skipped for a specific
	reason, rather than due to some bug.

	In gdbarch_components.py I've had to add 'invalid=True' for two
	components: gcore_bfd_target and max_insn_length, without this the
	validation in the gdbarch getter would disappear.

	And in gdbarch.py I've reworked the logic for generating the
	verify_gdbarch function, and for generating the getter functions.

	The logic for generating the getter functions is still not ideal,  I
	ended up having to add this additional logic block:

	  elif c.postdefault is not None and c.predefault is not None:
	      print("  /* Check variable changed from pre-default.  */", file=f)
	      print(f"  gdb_assert (gdbarch->{c.name} != {c.predefault});", file=f)

	which was needed to ensure we continued to generate the same code as
	before, without this the fact that invalid is now False when it would
	previously have been None, meant that we dropped the gdb_assert in
	favour of a comment like:

	  print(f"  /* Skip verify of {c.name}, invalid_p == 0 */", file=f)

	which is clearly not a good change.  We could potentially look at
	improving this in a later commit, but I don't plan to do that in this
	series.

	gdb/gdbarch: split postdefault setup from invalid check in gdbarch.py
	Restructure how gdbarch.py generates the verify_gdbarch function.
	Previously the postdefault handling was bundled together with the
	validation.  This means that a field can't have both a postdefault,
	and set its invalid attribute to a string.

	This doesn't seem reasonable to me, I see no reason why a field can't
	have both a postdefault (used when the tdep doesn't set the field),
	and an invalid expression, which can be used to validate the value
	that a tdep might set.

	In this commit I restructure the verify_gdbarch generation code to
	allow the above, there is no change in the actual generated code in
	this commit, that will come in later commit.

	Due to the algorithm used in gdbarch.py for generated verify_gdbarch,

	Fix crash in inside_main_func
	gdb 13.1 crashes while running the rust compiler's debugger tests.
	The crash has a number of causes.

	First, the rust compiler still uses the C++-like _Z mangling, but with
	its own twist -- some hex digits added to the end of a symbol.  So,
	while gdb finds the correct name of "main":

	(top-gdb) p name
	$13 = 0x292e0c0 "rustc_gdb_1031745::main"

	It isn't found in the minsyms, because C++ demangling yields:

	[99] t 0x90c0 _ZN17rustc_gdb_10317454main17h5b5be7fe16a97225E section .text  rustc_gdb_1031745::main::h5b5be7fe16a97225  zko06yobckx336v

	This could perhaps be fixed.  I also filed a new PR to suggest
	preferring the linkage name of the main program.

	Next, the rust compiler emits both a DW_TAG_subprogram and a
	DW_TAG_namespace for "main".  This happens because the file is named
	"main.rs" -- i.e., the bug is specific to the source file name.  The
	crash also seems to require the nested function inside of 'main', at
	least for me.  The namespace always is generated, but perhaps this
	changes the ordering in the DWARF.

	When inside_main_func looks up the main symbol, it finds the namespace
	symbol rather than the function.  (I filed a bug about fixing gdb's
	symbol tables -- long overdue.)

	Meanwhile, as I think it's important to fix this crash sooner rather
	than later, this patch changes inside_main_func to check that the
	symbol that is found is LOC_BLOCK.  This perhaps should have been done
	in the first place, anyway.

	[gdb/testsuite] Fix untested message in gdb.tui/corefile-run.exp
	In test-case gdb.tui/corefile-run.exp, we have this bit:
	...
	require !use_gdb_stub
	if { [target_info gdb_protocol] == "extended-remote" } {
	    untested "not supported"
	    return
	}
	...

	So with target board native-gdbserver we get:
	...
	UNSUPPORTED: gdb.tui/corefile-run.exp: require failed: !use_gdb_stub
	...
	and with target board native-extended-gdbserver instead:
	...
	UNTESTED: gdb.tui/corefile-run.exp: not supported
	...

	Fix this by:
	- adding an optional argument target_description to proc
	  target_can_use_run_cmd
	- handling the target_description == core &&
	  [target_info gdb_protocol] == "extended-remote" case in the proc
	- using require {target_can_use_run_cmd core}
	such that now in both cases we have:
	...
	UNSUPPORTED: gdb.tui/corefile-run.exp: require failed: \
	  target_can_use_run_cmd core

	gdb/testsuite: add regression test for per-objfile typeprinters
	PR python/17136 reported an unhandled exception when using typeprinters

	Change linetables to be objfile-independent
	This changes linetables to not add the text offset to the addresses
	they contain.  I did this in a few steps, necessarily combined
	together in one patch: I renamed the 'pc' member to 'm_pc', added the
	appropriate accessors, and then recompiled.  Then I fixed all the
	errors.  Where possible I generally chose to use the raw_pc accessor,
	as it is less expensive.

	Note that this patch discounts the possibility that the text section
	offset might cause wraparound in the addresses in the line table.
	However, this was already discounted -- in particular,
	objfile_relocate1 did not re-sort the table in this scenario.  (There
	was a bug open about this, but as far as I can tell this has never
	happened, it's not even clear what inspired that bug.)

	Some systems may install binutils headers into a system location
	(e.g. /usr/local/include on FreeBSD) which may also include headers
	for other external packages used by GDB such as zlib or zstd.  If a
	system include path such as /usr/local/include is added before local
	include paths to directories within a clone or release tarball, then
	headers from the external binutils package are used which can result
	in build failures if the external binutils package is out of sync with
	the version of GDB being built.

	To fix, sort the include paths in INTERNAL_CFLAGS_BASE to add CFLAGS
	for "local" componenets before external components.

	[gdb/testsuite] Fix gdb.python/py-cmd.exp
	[ Using $pp as shorthand for the pagination prompt
	"--Type <RET> for more, q to quit, c to continue without paging--". ]

	The test-case gdb.python/py-cmd.exp passes, but the handling of the
	test_multiline command output looks a bit odd:
	...
	(gdb) test_multiline
	test_multiline output
	  ...
	test_multiline output
	$ppPASS: gdb.python/py-cmd.exp: verify pagination from test_multiline
	q
	test_multiline
	Quit
	(gdb) test_multiline
	test_multiline output
	  ...
	test_multiline output
	$ppPASS: gdb.python/py-cmd.exp: verify pagination from test_multiline: q
	...

	What happens is:
	- a test_multiline command is issued
	- some output is printed, followed by a pagination prompt
	- the test-case concludes that pagination occurred, and produces a PASS
	- "q\n" is replied to the pagination prompt
	- without waiting for response to the "q\n", another test_multiline command is
	  issued
	- in response to the "q\n" we get "Quit\n(gdb) "
	- some output is printed, followed by a pagination prompt
	- the test-case concludes that there's a valid response to the "q\n", and
	  produces a PASS, consuming the second pagination prompt, but without a reply.

	My conclusion is that the second test_multiline command is unintentional, so fix
	this by removing it.

	Without it, we have the more straightforward:
	...
	(gdb) test_multiline
	test_multiline output
	  ...
	test_multiline output
	$ppPASS: gdb.python/py-cmd.exp: verify pagination from test_multiline

	Arm64/gas: drop redundant feature prereqs
	Logic exists to deal with prereqs or prereqs, and in many cases
	transitive prereqs are already not spelled out explicitly. Drop further
	ones:
	- FP is already a prereq to F16,
	- SIMD and F16 are already prereqs to COMPNUM, and
	- SVE2 and BFLOAT16 are already prereqs to SME.

	Arm64/gas: add missing prereq features
	A number of newer features are really SIMD or FP extensions, but don't
	have this properly specified.

	x86: decouple broadcast type and bytes fields
	Keep both representing exclusively what was parsed from input, to avoid
	the need for (potentially bogus) calculations when processing .insn.

	x86-64: adjust REX-prefix part of SSE2AVX test
	Before altering how build_modrm_byte() works, arrange for this part of
	the testcase to actually use distinguishable source and destination
	register numbers, such that incorrect propagation of, in particular, the
	high bit encodings (from REX to VEX) can be noticed (in turn
	specifically assertions [not] triggering in the respective code).

	x86: move more disp processing out of md_assemble()
	Put it in optimize_disp() such that it can then be re-used by .insn
	handling. The movement makes it necessary (or at least very desirable,
	to avoid introducing a fragile cast) to convert to local variable to
	"unsigned", which in turn requires an adjustment to the pre-existing
	loop header.

	Having the caller pass in the specific template under consideration has
	another benefit then: We can replace the two uses of current_templates
	in the function as well, thus no longer looking at some merely "related"
	template. (This may allow further tightening, but if so that's to be the
	subject of another change.)

	[gdb/testsuite] Fix gdb.server/server-kill.exp for remote target
	In commit 80dc83fd0e7 ("gdb/remote: handle target dying just before a stepi")
	an observation is made that test-case gdb.server/server-kill.exp claims to
	kill gdbserver, but actually kills the inferior.  Consequently, the commit
	adds testing of killing gdbserver alongside.

	The problem is that:
	- the original observation is incorrect (possibly caused by misreading getppid
	  as getpid)
	- consequently, the test-case doesn't test killing the inferior, instead it
	  tests killing gdbserver twice
	- the method to get the gdbserver PID added in the commit doesn't work
	  for target board remote-gdbserver-on-localhost, it returns the
	  PID of the ssh client session instead.

	Fixing the method for getting the inferior PID gives us fails, and there's no
	evidence that killing the inferior ever worked.

	So, fix this by reverting the commit and just killing gdbserver, using the
	original method of getting the gdbserver PID which does work for target board
	remote-gdbserver-on-localhost.

	Tested on x86_64-linux.

	[gdb/testsuite] Fix gdb.server/connect-with-no-symbol-file.exp for remote target
	Test-case gdb.server/connect-with-no-symbol-file.exp fails with target board
	remote-gdbserver-on-localhost.

	The problem is here:
	...
	       set target_exec [gdb_remote_download target $binfile.bak $binfile]
	...
	A "gdb_remote_download target" copies from build to target.  So $binfile is
	assumed to be a target path, but it's actually a build path.

	Fix this by:
	- fist copying $binfile.bak to $binfile, and
	- simply doing [gdb_remote_download target $binfile].

	Then, $binfile.bak is created here:
	...
	 # Make sure we have the original symbol file in a safe place to copy from.
	 gdb_remote_download host $binfile $binfile.bak
	...
	and since "gdb_remote_download host" copies from build to host, $binfile.bak
	is assumed to be a host path, but it's actually a build path.  This happens to
	cause no problems in this configuration (because build == host), but it would
	for a remote host configuration.

	So let's fix this by making build rather than host the "safe place to copy
	from".

	Tested on x86_64-linux.

	PowerPC, fix test gdb.arch/altivec-regs.exp
	The test fails on Power 10 with the RHEL9 distro.  It also fails on
	Power 9.

	The test set a the breakpoint in main that stops at line:
	a = 9; /* start here */.  The test then sets a break point at the same
	line where it wants to start the test and does a continue.  GDB does not
	stop again on the same line where it is stopped, but rather continues to
	the end of the program.

	Initialize variable A to zero so the break on main will stop before setting
	a break point on line a = 9; /* start here */.

	Make the match on the breakpoint number generic.

	Patch has been tested on Power 10 with RHEL 9, Power 10 with Ubuntu 22.04,
	and Power 9 with Fedora 36 with no regression failures.

	gdb/amdgpu: provide dummy implementation of gdbarch_return_value_as_value
	The AMD GPU support has been merged shortly after commit 4e1d2f5814b2
	("Add new overload of gdbarch_return_value"), which made it mandatory
	for architectures to provide either a return_value or
	return_value_as_value implementation.  Because of my failure to test
	properly after rebasing and before pushing, we get this with the current
	master:

	    $ gdb ./gdb -nx --data-directory=data-directory -q -ex "set arch amdgcn:gfx1010" -batch
	    /home/simark/src/binutils-gdb/gdb/gdbarch.c:517: internal-error: verify_gdbarch: the following are invalid ...
	            return_value_as_value

	I started trying to change GDB to not force architectures to provide a
	return_value or return_value_as_value implementation, but Andrew pointed
	out that any serious port will have an implementation one day or
	another, and it's easy to add a dummy implementation in the mean time.
	So it's better to not complicate the core of GDB to know how to deal
	with this.

	There is an implementation of return_value in the downstream ROCgdb port
	(which we'll need to convert to the new return_value_as_value), which
	we'll contribute soon-ish.  In the mean time, add a dummy implementation
	of return_value_as_value to avoid the failed assertion.

	Clean up attribute reprocessing
	I ran across the attribute reprocessing code recently and noticed that
	it unconditionally sets members of the CU when reading a DIE.  Also,
	each spot reading attributes needs to be careful to "reprocess" them
	as a separate step.

	This seemed excessive to me, because while reprocessing applies to any
	DIE, setting the CU members is only necessary for the toplevel DIE in
	any given CU.

	This patch introduces a new read_toplevel_die function and changes a
	few spots to call it.  This is easily done because reading the
	toplevel DIE is already special.

	I left the reprocessing flag and associated checks in attribute.  It
	could be stripped out, but I am not sure it would provide much value
	(maybe some iota of performance).

	Regression tested on x86-64 Fedora 36.

	gdb: make interp::m_name an `const char *`
	I realized that the memory for interp names does not need to be

	a literal string, so has static storage duration.  If we change
	interp_lookup to pass that name instead of the string that it receives
	as a parameter (which does not always have static storage duration),
	then interps can simply store pointers to the name.

	So, change interp_lookup to pass `factory.name` rather than `name`.

	[gdb/testsuite] Fix gdb.base/signals-state-child.exp for remote-gdbserver-on-localhost
	With test-case gdb.base/signals-state-child.exp on target board
	remote-gdbserver-on-localhost I run into:
	...
	builtin_spawn /usr/bin/ssh -t -l remote-target localhost \
	  $outputs/gdb.base/signals-state-child/signals-state-child-standalone^M
	bash: $outputs/gdb.base/signals-state-child/signals-state-child-standalone: \
	  Permission denied^M
	Connection to localhost closed.^M^M
	FAIL: gdb.base/signals-state-child.exp: collect standalone signals state
	...

	The problem is that we're trying to run an executable on the target board using
	a host path.

	After fixing this by downloading the exec to the target board, we run into:
	...
	builtin_spawn /usr/bin/ssh -t -l remote-target localhost \
	  signals-state-child-standalone^M
	bash: signals-state-child-standalone: command not found^M
	Connection to localhost closed.^M^M
	FAIL: gdb.base/signals-state-child.exp: collect standalone signals state
	...

	Fix this by using an absolute path name for the exec on the target board.

	The dejagnu proc standard_file does not support op == "absolute" for target
	boards, so add an implementation in remote-gdbserver-on-localhost.exp.

	Also:
	- fix a PATH-in-test-name issue
	- cleanup gdb.txt and standalone.txt on target board

	Tested on x86_64-linux.

	Fix these (and make things more similar to the gdb.exp procs) by:
	- factoring out mi_load_shlib out of mi_load_shlibs
	- making mi_load_shlib use gdb_download_shlib, like
	  gdb_load_shlib
	- factoring out mi_locate_shlib out of mi_load_shlib
	- making mi_locate_shlib check for mi_spawn_id, like

	gdbsupport: ignore -Wenum-constexpr-conversion in enum-flags.h
	When building with clang 16, we get:

	      CXX    gdb.o
	    In file included from /home/smarchi/src/binutils-gdb/gdb/gdb.c:19:
	    In file included from /home/smarchi/src/binutils-gdb/gdb/defs.h:65:
	    /home/smarchi/src/binutils-gdb/gdb/../gdbsupport/enum-flags.h:95:52: error: integer value -1 is outside the valid range of values [0, 15] for this enumeration type [-Wenum-constexpr-conversion]
	        integer_for_size<sizeof (T), static_cast<bool>(T (-1) < T (0))>::type
	                                                       ^

	The error message does not make it clear in the context of which enum
	flag this fails (i.e. what is T in this context), but it doesn't really
	matter, we have similar warning/errors for many of them, if we let the
	build go through.

	clang is right that the value -1 is invalid for the enum type we cast -1
	to.  However, we do need this expression in order to select an integer
	type with the appropriate signedness.  That is, with the same signedness
	as the underlying type of the enum.

	I first wondered if that was really needed, if we couldn't use
	std::underlying_type for that.  It turns out that the comment just above
	says:

	    /* Note that std::underlying_type<enum_type> is not what we want here,
	       since that returns unsigned int even when the enum decays to signed
	       int.  */

	I was surprised, because std::is_signed<std::underlying_type<enum_type>>
	returns the right thing.  So I tried replacing all this with
	std::underlying_type, see if that would work.  Doing so causes some
	build failures in unittests/enum-flags-selftests.c:

	      CXX    unittests/enum-flags-selftests.o

	      ^              ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

	This is a bit hard to decode, but basically enumerations have the
	following funny property that they decay into a signed int, even if
	their implicit underlying type is unsigned.  This code:

	    enum A {};
	    enum B {};

	    int main() {
	      std::cout << std::is_signed<std::underlying_type<A>::type>::value
	                << std::endl;
	      std::cout << std::is_signed<std::underlying_type<B>::type>::value
	                << std::endl;
	      auto result = true ? A() : B();
	      std::cout << std::is_signed<decltype(result)>::value << std::endl;
	    }

	produces:

	    0
	    0
	    1

	So, the "CHECK_VALID" above checks that this property works for enum flags the
	same way as it would if you were using their underlying enum types.  And
	somehow, changing integer_for_size to use std::underlying_type breaks that.

	Since the current code does what we want, and I don't see any way of doing it
	differently, ignore -Wenum-constexpr-conversion around it.

	gdb/testsuite: use `kill -FOO` instead of `kill -SIGFOO`
	When running gdb.base/bg-exec-sigint-bp-cond.exp when SHELL is dash,
	rather than bash, I get:

	    c&^M
	    Continuing.^M
	    (gdb) sh: 1: kill: Illegal option -S^M
	    ^M
	    Breakpoint 2, foo () at /home/jenkins/smarchi/binutils-gdb/build/gdb/testsuite/../../../gdb/testsuite/gdb.base/bg-exec-sigint-bp-cond.c:23^M
	    23        return 0;^M
	    FAIL: gdb.base/bg-exec-sigint-bp-cond.exp: no force memory write: SIGINT does not interrupt background execution (timeout)

	This is because it uses the kill command built-in the dash shell, and
	using the SIG prefix with kill does not work with dash's kill.  The
	difference is listed in the documentation for bash's POSIX-correct mode
	[1]:

	    The kill builtin does not accept signal names with a ‘SIG’ prefix.

	Replace SIGINT with INT in that test.

	By grepping, I found two other instances (gdb.base/sigwinch-notty.exp
	and gdb.threads/detach-step-over.exp).  Those were not problematic on my
	system though.  Since they are done through remote_exec, they don't go
	through the shell and therefore invoke /bin/kill.  On my Arch Linux,
	it's:

	    $ /bin/kill --version
	    kill from util-linux 2.38.1 (with: sigqueue, pidfd)

	and on my Ubuntu:

	    $ /bin/kill --version
	    kill from procps-ng 3.3.17

	These two implementations accept "-SIGINT".  But according to the POSIX
	spec [2], the kill utility should recognize the signal name without the
	SIG prefix (if it recognizes them with the SIG prefix, it's an
	extension):

	    -s  signal_name
	        Specify the signal to send, using one of the symbolic names defined
		in the <signal.h> header. Values of signal_name shall be recognized
		in a case-independent fashion, without the SIG prefix. In addition,
		the symbolic name 0 shall be recognized, representing the signal
		value zero. The corresponding signal shall be sent instead of SIGTERM.
	    -signal_name
	        [XSI] [Option Start]
	        Equivalent to -s signal_name. [Option End]

	So, just in case some /bin/kill implementation happens to not recognize
	the SIG prefixes, change these two other calls to remove the SIG
	prefix.

	gdb: fix -Wmaybe-uninitialized warning in value.c
	Since commit 11470e70ea0d ("gdb: store internalvars in an std::map"), bulding
	with -O2, with g++ 11.3.0 on Ubuntu 22.04, I see:

	      CXX    value.o
	    In constructor ‘internalvar::internalvar(internalvar&&)’,
	        inlined from ‘constexpr std::pair<_T1, _T2>::pair(_U1&&, _U2&&) [with _U1 = const char*&; _U2 = internalvar; typename std::enable_if<(std::_PCC<true, _T1, _T2>::_MoveConstructiblePair<_U1, _U2>() && std::_PCC<true, _T1, _T2>::_ImplicitlyMoveConvertiblePair<_U1, _U2>()), bool>::type <anonymous> = true; _T1 = const char*; _T2 = internalvar]’ at /usr/include/c++/11/bits/stl_pair.h:353:35,

	        inlined from ‘internalvar* create_internalvar(const char*)’ at /home/smarchi/src/binutils-gdb/gdb/value.c:1933:52:
	    /home/smarchi/src/binutils-gdb/gdb/value.c:1831:8: warning: ‘<unnamed>.internalvar::u’ may be used uninitialized [-Wmaybe-uninitialized]
	     1831 | struct internalvar

	    /home/smarchi/src/binutils-gdb/gdb/value.c: In function ‘internalvar* create_internalvar(const char*)’:
	    /home/smarchi/src/binutils-gdb/gdb/value.c:1933:76: note: ‘<anonymous>’ declared here

	This is because the union field internalvar::u is not initialized when
	constructing the temporary internalvar object above.  That object is then used
	for move-construction, and the (implicit) move constructor copies the
	uninitialized bytes of field u over from the temporary object to the new
	internalvar object.  The compiler therefore complains that we use uninitialized
	bytes.  I don't think it's really a problem, because the internalvar object is
	in the `kind == INTERNALVAR_VOID` state, in which the contents of the union is
	irrelevant.  Still, mute the warning by default-initializing the union.

	[gdb/symtab] Add set/show always-read-ctf on/off
	[ This is a simplified rewrite of an earlier submission "[RFC][gdb/symtab] Add
	maint set symbol-read-order", submitted here (
	https://sourceware.org/pipermail/gdb-patches/2022-September/192044.html
	). ]

	With the test-case included in this patch, we run into:
	...
	(gdb) file dwarf2-and-ctf
	(gdb) print var_ctf^M
	'var_ctf' has unknown type; cast it to its declared type^M
	...

	The problem is that the executable contains both ctf and dwarf2, so the ctf
	info (which contains the type information about var_ctf) is ignored.

	GDB has support for handling multiple debug formats, but the common use case
	for ctf is to be used when dwarf2 is not present, and gdb reflects that,
	assuming that by reading ctf in addition there won't be any extra information,
	so it's not worth the additional cycles and memory.

	Add a new command "set/show always-read-ctf on/off", that when on forces
	unconditional reading of ctf, allowing us to do:
	...
	(gdb) set always-read-ctf on
	(gdb) file dwarf2-and-ctf
	(gdb) print var_ctf^M
	$2 = 2^M
	...

	The setting is off by default, preserving current behaviour.

	A bit of background on the relevance of reading order: the formats have a
	priority relationship between them, where reading earlier means lower
	priority.  By reading the format with the most detail last, we ensure it has
	the highest priority, which makes sure that in case there is overlapping info,
	the most detailed info is found.  This explains the current reading order of
	mdebug, stabs and dwarf2.

	Add the unconditional reading of ctf before dwarf2, because it's less detailed
	than dwarf2.  The conditional reading of ctf is still done after the attempt to
	read dwarf2, necessarily so because we only know whether there's dwarf2 after
	we've tried to read it.

	The new command allow us to replace uses of -Wl,--strip-debug added in commit
	908a926ec4e ("[gdb/testsuite] Fix ctf test-cases on openSUSE Tumbleweed") by
	uses of "set always-read-ctf on", but I've left that for another commit.

	Tested on x86_64-linux.

	gdb: add HtabPrinter to gdb-gdb.py.in
	When debugging GDB, I find it a bit tedious to inspect htab_t objects.
	It is possible to find the entries by poking at the fields, but it's
	annoying to do each time.  I think a pretty printer would help.  Add a
	basic one to gdb-gdb.py.

	The pretty printer advertises itself as "array-like", and the result
	looks like:

	    $3 = htab_t with 3 elements = {0x6210003252a0, 0x62100032caa0, 0x62100033baa0}

	The htab_t itself doesn't know about the type of pointed objects.  But
	it's easy enough to cast the addresses to the right type to use them:

	    (top-gdb) print *((btrace_frame_cache *) 0x6210003252a0)
	    $6 = {tp = 0x61700002ed80, frame = 0x6210003251e0, bfun = 0x62000000b390}

	gdb: fix mi breakpoint-deleted notifications for thread-specific b/p
	Background
	----------

	When a thread-specific breakpoint is deleted as a result of the
	specific thread exiting the function remove_threaded_breakpoints is
	called which sets the disposition of the breakpoint to
	disp_del_at_next_stop and sets the breakpoint number to 0.  Setting
	the breakpoint number to zero has the effect of hiding the breakpoint
	from the user.  We also print a message indicating that the breakpoint
	has been deleted.

	It was brought to my attention during a review of another patch[1]
	that setting a breakpoints number to zero will suppress the MI
	breakpoint-deleted notification for that breakpoint, and indeed, this
	can be seen to be true, in delete_breakpoint, if the breakpoint number
	is zero, then GDB will not notify the breakpoint_deleted observer.

	It seems wrong that a user created, thread-specific breakpoint, will
	have a =breakpoint-created notification, but will not have a
	=breakpoint-deleted notification.  I suspect that this is a bug.

	[1] https://sourceware.org/pipermail/gdb-patches/2023-February/196560.html

	The First Problem
	-----------------

	During my initial testing I wanted to see how GDB handled the
	breakpoint after it's number was set to zero.  To do this I created
	the testcase gdb.threads/thread-bp-deleted.exp.  This test creates a
	worker thread, which immediately exits.  After the worker thread has
	exited the main thread spins in a loop.

	In GDB I break once the worker thread has been created and place a
	thread-specific breakpoint, then use 'continue&' to resume the
	inferior in non-stop mode.  The worker thread then exits, but the main
	thread never stops - instead it sits in the spin.  I then tried to use
	'maint info breakpoints' to see what GDB thought of the
	thread-specific breakpoint.

	Unfortunately, GDB crashed like this:

	  (gdb) continue&
	  Continuing.
	  (gdb) [Thread 0x7ffff7c5d700 (LWP 1202458) exited]
	  Thread-specific breakpoint 3 deleted - thread 2 no longer in the thread list.
	  maint info breakpoints
	  ... snip some output ...

	  Fatal signal: Segmentation fault

	  0x5b58b8 maintenance_info_breakpoints
	          ../../src/gdb/breakpoint.c:7009
	  ... etc ...

	As the thread-specific breakpoint is set to disp_del_at_next_stop, and
	GDB hasn't stopped yet, then the breakpoint still exists in the global
	breakpoint list.

	The breakpoint will not show in 'info breakpoints' as its number is
	zero, but it will show in 'maint info breakpoints'.

	As GDB prints the breakpoint, the thread-id for the breakpoint is
	printed as part of the 'stop only in thread ...' line.  Printing the
	thread-id involves calling find_thread_global_id to convert the global
	thread-id into a thread_info*.  Then calling print_thread_id to
	convert the thread_info* into a string.

	The problem is that find_thread_global_id returns nullptr as the
	thread for the thread-specific breakpoint has exited.  The
	print_thread_id assumes it will be passed a non-nullptr.  As a result
	GDB crashes.

	In this commit I've added an assert to print_thread_id (gdb/thread.c)
	to check that the pointed passed in is not nullptr.  This assert would
	have triggered in the above case before GDB crashed.

	MI Notifications: The Dangers Of Changing A Breakpoint's Number
	---------------------------------------------------------------

	Currently the delete_breakpoint function doesn't trigger the
	breakpoint_deleted observer for any breakpoint with the number zero.

	There is a comment explaining why this is the case in the code; it's
	something about watchpoints.  But I did consider just removing the 'is
	the number zero' guard and always triggering the breakpoint_deleted
	observer, figuring that I'd then fix the watchpoint issue some other
	way.

	But I realised this wasn't going to be good enough.  When the MI
	notification was delivered the number would be zero, so any frontend
	parsing the notifications would not be able to match
	=breakpoint-deleted notification to the earlier =breakpoint-created
	notification.

	What this means is that, at the point the breakpoint_deleted observer
	is called, the breakpoint's number must be correct.

	MI Notifications: The Dangers Of Delaying Deletion
	--------------------------------------------------

	The test I used to expose the above crash also brought another problem
	to my attention.  In the above test we used 'continue&' to resume,
	after which a thread exited, but the inferior didn't stop.  Recreating
	the same test in the MI looks like this:

	  -break-insert -p 2 main
	  ^done,bkpt={number="2",type="breakpoint",disp="keep",...<snip>...}
	  (gdb)
	  -exec-continue
	  ^running
	  *running,thread-id="all"
	  (gdb)
	  ~"[Thread 0x7ffff7c5d700 (LWP 987038) exited]\n"
	  =thread-exited,id="2",group-id="i1"
	  ~"Thread-specific breakpoint 2 deleted - thread 2 no longer in the thread list.\n"

	At this point the we have a single thread left, which is still
	running:

	  -thread-info
	  ^done,threads=[{id="1",target-id="Thread 0x7ffff7c5eb80 (LWP 987035)",name="thread-bp-delet",state="running",core="4"}],current-thread-id="1"
	  (gdb)

	Notice that we got the =thread-exited notification from GDB as soon as
	the thread exited.  We also saw the CLI line from GDB, the line
	explaining that breakpoint 2 was deleted.  But, as expected, we didn't
	see the =breakpoint-deleted notification.

	I say "as expected" because the number was set to zero.  But, even if
	the number was not set to zero we still wouldn't see the
	notification.  The MI notification is driven by the breakpoint_deleted
	observer, which is only called when we actually delete the breakpoint,
	which is only done the next time GDB stops.

	Now, maybe this is fine.  The notification is delivered a little
	late.  But remember, by setting the number to zero the breakpoint will
	be hidden from the user, for example, the breakpoint is removed from
	the MI's -break-info command output.

	This means that GDB is in a position where the breakpoint doesn't show
	up in the breakpoint table, but a =breakpoint-deleted notification has
	not yet been sent out.  This doesn't seem right to me.

	What this means is that, when the thread exits, we should immediately
	be sending out the =breakpoint-deleted notification.  We should not
	wait for GDB to next stop before sending the notification.

	The Solution
	------------

	My proposed solution is this; in remove_threaded_breakpoints, instead
	of setting the disposition to disp_del_at_next_stop and setting the
	number to zero, we now just call delete_breakpoint directly.

	The notification will now be sent out immediately; as soon as the
	thread exits.

	As the number has not changed when delete_breakpoint is called, the
	notification will have the correct number.

	And as the breakpoint is immediately removed from the breakpoint list,
	we no longer need to worry about 'maint info breakpoints' trying to
	print the thread-id for an exited thread.

	My only concern is that calling delete_breakpoint directly seems so
	obvious that I wonder why the original patch (that added
	remove_threaded_breakpoints) didn't take this approach.  This code was
	added in commit 49fa26b0411d, but the commit message offers no clues
	to why this approach was taken, and the original email thread offers
	no insights either[2].  There are no test regressions after making
	this change, so I'm hopeful that this is going to be fine.

	[2] https://sourceware.org/pipermail/gdb-patches/2013-September/106493.html

	The Complication
	----------------

	Of course, it couldn't be that simple.

	The script gdb.python/py-finish-breakpoint.exp had some regressions
	during testing.

	The problem was with the FinishBreakpoint.out_of_scope callback
	implementation.  This callback is supposed to trigger whenever the
	FinishBreakpoint goes out of scope; and this includes when the thread
	for the breakpoint exits.

	The problem I ran into is the Python FinishBreakpoint implementation.
	Specifically, after this change I was loosing some of the out_of_scope
	calls.

	The problem is that the out_of_scope call (of which I'm interested) is
	triggered from the inferior_exit observer.  Before my change the
	observers were called in this order:

	  thread_exit
	  inferior_exit
	  breakpoint_deleted

	The inferior_exit would trigger the out_of_scope call.

	After my change the breakpoint_deleted notification (for
	thread-specific breakpoints) occurs earlier, as soon as the
	thread-exits, so now the order is:

	  thread_exit
	  breakpoint_deleted
	  inferior_exit

	Currently, after the breakpoint_deleted call the Python object
	associated with the breakpoint is released, so, when we get to the
	inferior_exit observer, there's no longer a Python object to call the
	out_of_scope method on.

	My solution is to follow the model for how bpfinishpy_pre_stop_hook
	and bpfinishpy_post_stop_hook are called, this is done from
	gdbpy_breakpoint_cond_says_stop in py-breakpoint.c.

	I've now added a new bpfinishpy_pre_delete_hook
	gdbpy_breakpoint_deleted in py-breakpoint.c, and from this new hook
	function I check and where needed call the out_of_scope method.

	With this fix in place I now see the
	gdb.python/py-finish-breakpoint.exp test fully passing again.

	Testing
	-------

	Tested on x86-64/Linux with unix, native-gdbserver, and
	native-extended-gdbserver boards.

	New tests added to covers all the cases I've discussed above.

	gdb/testsuite: fix failure in gdb.mi/mi-pending.exp with extended-remote
	I currently see this failure when running the gdb.mi/mi-pending.exp
	test using the native-extended-remote board:

	  -break-insert -f -c x==4 mi-pendshr.c:pendfunc2
	  &"No source file named mi-pendshr.c.\n"
	  ^done,bkpt={number="2",type="breakpoint",disp="keep",enabled="y",addr="<PENDING>",pending="mi-pendshr.c:pendfunc2",cond="x==4",evaluated-by="host",times="0",original-location="mi-pendshr.c:pendfunc2"}
	  (gdb)
	  FAIL: gdb.mi/mi-pending.exp: MI pending breakpoint on mi-pendshr.c:pendfunc2 if x==4 (unexpected output)

	The failure is caused by the 'evaluated-by="host"' string, which only
	appears in the output when the test is run using the
	native-extended-remote board.

	I could fix this by just updating the pattern in
	gdb.mi/mi-pending.exp, but I have instead updated mi-pending.exp to
	make more use of the support procs in mi-support.exp.  This did
	require making a couple of adjustments to mi-support.exp, but I think
	the result is that mi-pending.exp is now easier to read, and I see no
	failures with native-extended-remote anymore.

	One of the test names has changed after this work, I think the old
	test name was wrong - it described a breakpoint as pending when the
	breakpoint was not pending, I suspect a copy & paste error.

	But there's no changes to what is actually being tested after this
	patch.

	gdb/testsuite: introduce is_target_non_stop helper proc

	gdb/testsuite introduce foreach_mi_ui_mode helper proc
	Introduce foreach_mi_ui_mode, a helper proc which can be used when
	tests are going to be repeated once with the MI in the main UI, and
	once with the MI on a separate UI.

	The proc is used like this:

	  foreach_mi_ui_mode VAR {
	    # BODY
	  }

	The BODY will be run twice, once with VAR set to 'main' and once with
	VAR set to 'separate', inside BODY we can then change the behaviour
	based on the current UI mode.

	The point of this proc is that we sometimes shouldn't run the separate
	UI tests (when gdb_debug_enabled is true), and this proc hides all
	this logic.  If the separate UI mode should not be used then BODY will
	be run just once with VAR set to 'main'.

	I've updated two tests that can make use of this helper proc.  I'm
	going to add another similar test in a later commit.

	There should be no change to what is tested with this commit.

	In this commit I add an extra (optional) argument to the

	flags to mi_gdb_start, and avoids having to otherwise duplicate the

	gdb: don't duplicate 'thread' field in MI breakpoint output
	When creating a thread-specific breakpoint with a single location, the
	'thread' field would be repeated in the MI output.  This can be seen
	in two existing tests gdb.mi/mi-nsmoribund.exp and
	gdb.mi/mi-pending.exp, e.g.:

	  (gdb)
	  -break-insert -p 1 bar
	  ^done,bkpt={number="1",type="breakpoint",disp="keep",
		      enabled="y",
		      addr="0x000000000040110a",func="bar",
		      file="/tmp/mi-thread-specific-bp.c",
		      fullname="/tmp/mi-thread-specific-bp.c",
		      line="32",thread-groups=["i1"],
		      thread="1",thread="1",  <================ DUPLICATION!
		      times="0",original-location="bar"}

	I know we need to be careful when adjusting MI output, but I'm hopeful
	in this case, as the field is duplicated, and the field contents are
	always identical, that we might get away with removing one of the
	duplicates.

	The change in GDB is a fairly trivial condition change.

	We did have a couple of tests that contained the duplicate fields in
	their expected output, but given there was no comment pointing out
	this oddity either in the GDB code, or in the test, I suspect this was
	more a case of copying whatever output GDB produced and using that as
	the expected results.  I've updated these tests to remove the
	duplication.

	I've update lib/mi-support.exp to provide support for building
	breakpoint patterns that contain the thread field, and I've made use
	of this in a new test I've added that is just about creating
	thread-specific breakpoints and checking the results.  The two tests I
	mentioned above as being updated could also use the new
	lib/mi-support.exp functionality, but I'm going to do that in a later
	patch, this way it is clear what changes I'm actually proposing to
	make to the expected output.

	As I said, I hope that frontends will be able to handle this change,
	but I still think its worth adding a NEWS entry, that way, if someone
	runs into problems, there's a chance they can figure out what's going
	on.

	This should not impact CLI output at all.

	Forced quit cases handled by resetting sync_quit_force_run
	During my audit of the use of gdb_exception with regard to QUIT
	processing, I found a try/catch in the scoped_switch_fork_info
	destructor.

	Static analysis found this call path from the destructor to
	maybe_quit():

	  scoped_switch_fork_info::~scoped_switch_fork_info()
	    -> remove_breakpoints()
	    -> remove_breakpoint(bp_location*)
	    -> remove_breakpoint_1(bp_location*, remove_bp_reason)
	    -> memory_validate_breakpoint(gdbarch*, bp_target_info*)
	    -> target_read_memory(unsigned long, unsigned char*, long)
	    -> target_read(target_ops*, target_object, char const*, unsigned char*, unsigned long, long)
	    -> maybe_quit()

	Since it's not safe to do a 'throw' from a destructor, we simply
	call set_quit_flag and, for gdb_exception_forced_quit, also
	set sync_quit_force_run.  This will cause the appropriate
	exception to be rethrown at the next QUIT check.

	Another case is the try / catch in tui_getc() in tui-io.c.  The
	existing catch swallows the exception.  I've added a catch for
	'gdb_exception_forced_quit', which also swallows the exception,
	but also sets sync_quit_force_run and calls set_quit_flag in
	order to restart forced quit processing at the next QUIT check.
	This is required because it isn't safe to throw into/through
	readline.

	Thanks to Pedro Alves for suggesting this idea.

	QUIT processing w/ explicit throw for gdb_exception_forced_quit
	This commit contains changes which have an explicit throw for
	gdb_exception_forced_quit, or, in a couple of cases for gdb_exception,
	but with a throw following a check to see if 'reason' is
	RETURN_FORCED_QUIT.

	Most of these are straightforward - it made sense to continue to allow
	an existing catch of gdb_exception to also catch gdb_exception_quit;
	in these cases, a catch/throw for gdb_exception_forced_quit was added.

	There are two cases, however, which deserve a more detailed
	explanation.

	1) remote_fileio_request in gdb/remote-fileio.c:

	The try block calls do_remote_fileio_request which can (in turn)
	call one of the functions in remote_fio_func_map[].  Taking the
	first one, remote_fileio_func_open(), we have the following call
	path to maybe_quit():

	  remote_fileio_func_open(remote_target*, char*)
	    -> target_read_memory(unsigned long, unsigned char*, long)
	    -> target_read(target_ops*, target_object, char const*, unsigned char*, unsigned long, long)
	    -> maybe_quit()

	Since there is a path to maybe_quit(), we must ensure that the
	catch block is not permitted to swallow a QUIT representing a
	SIGTERM.

	However, for this case, we must take care not to change the way that
	Ctrl-C / SIGINT is handled; we want to send a suitable EINTR reply to
	the remote target should that happen.  That being the case, I added a
	catch/throw for gdb_exception_forced_quit.  I also did a bit of
	rewriting here, adding a catch for gdb_exception_quit in favor of
	checking the 'reason' code in the catch block for gdb_exception.

	2) mi_execute_command in gdb/mi/mi-main.c:

	The try block calls captured_mi_execute_command(); there exists
	a call path to maybe_quit():

	  captured_mi_execute_command(ui_out*, mi_parse*)
	    -> mi_cmd_execute(mi_parse*)
	    -> get_current_frame()
	    -> get_prev_frame_always_1(frame_info*)
	    -> frame_register_unwind_location(frame_info*, int, int*, lval_type*, unsigned long*, int*)
	    -> frame_register_unwind(frame_info*, int, int*, int*, lval_type*, unsigned long*, int*, unsigned char*)
	    -> value_entirely_available(value*)
	    -> value_fetch_lazy(value*)
	    -> value_fetch_lazy_memory(value*)
	    -> read_value_memory(value*, long, int, unsigned long, unsigned char*, unsigned long)
	    -> maybe_quit()

	That being the case, we can't allow the exception handler (catch block)
	to swallow a gdb_exception_quit for SIGTERM.  However, it does seem
	reasonable to output the exception via the mi interface so that some
	suitable message regarding SIGTERM might be printed; therefore, I
	check the exception's 'reason' field for RETURN_FORCED_QUIT and
	do a throw for this case.

	Guile QUIT processing updates
	This commit contains QUIT processing updates for GDB's Guile support.
	As with the Python updates, we don't want to permit this code to
	swallow the exception, gdb_exception_forced_quit, which is associated
	with GDB receiving a SIGTERM.

	I've adopted the same solution that I used for Python; whereever
	a gdb_exception is caught in try/catch code in the Guile extension
	language support, a catch for gdb_exception_forced_quit has been
	added; this catch block will simply call quit_force(), which will
	cause the necessary cleanups to occur followed by GDB exiting.

	Python QUIT processing updates
	See the previous patches in this series for the motivation behind
	these changes.

	This commit contains updates to Python's QUIT handling.  Ideally, we'd
	like to throw gdb_exception_forced_quit through the extension
	language; I made an attempt to do this for gdb_exception_quit in an
	earlier version of this patch, but Pedro pointed out that it is
	(almost certainly) not safe to do so.

	Still, we definitely don't want to swallow the exception representing
	a SIGTERM for GDB, nor do we want to force modules written in the
	extension language to have to explicitly handle this case.  Since the
	idea is for GDB to cleanup and quit for this exception, we'll simply
	call quit_force() just as if the gdb_exception_forced_quit propagation
	had managed to make it back to the top level.

	Catch gdb_exception_error instead of gdb_exception (in many places)
	As described in the previous commit for this series, I became
	concerned that there might be instances in which a QUIT (due to either
	a SIGINT or SIGTERM) might not cause execution to return to the top
	level.  In some (though very few) instances, it is okay to not
	propagate the exception for a Ctrl-C / SIGINT, but I don't think that
	it is ever okay to swallow the exception caused by a SIGTERM.
	Allowing that to happen would definitely be a deviation from the
	current behavior in which GDB exits upon receipt of a SIGTERM.

	I looked at all cases where an exception handler catches a
	gdb_exception.  Handlers which did NOT need modification were those
	which satisifed one or more of the following conditions:

	  1) There is no call path to maybe_quit() in the try block.  I used a
	     static analysis tool to help make this determination.  In
	     instances where the tool didn't provide an answer of "yes, this
	     call path can result in maybe_quit() being called", I reviewed it
	     by hand.

	  2) The catch block contains a throw for conditions that it
	     doesn't want to handle; these "not handled" conditions
	     must include the quit exception and the new "forced quit" exception.

	  3) There was (also) a catch for gdb_exception_quit.

	Any try/catch blocks not meeting the above conditions could
	potentially swallow a QUIT exception.

	My first thought was to add catch blocks for gdb_exception_quit and
	then rethrow the exception.  But Pedro pointed out that this can be
	handled without adding additional code by simply catching
	gdb_exception_error instead.  That's what this patch series does.

	There are some oddball cases which needed to be handled differently,
	plus the extension languages, but those are handled in later patches.

	Handle gdb SIGTERM by throwing / catching gdb_exception_force_quit
	When a GDB process receives the SIGTERM signal, handle_sigterm() in
	event-top.c is called.  The global variable 'sync_quit_force_run' is
	set by this signal handler.  It does some other things too, but the
	setting of this global is the important bit for the SIGTERM part of
	this discussion.

	GDB will periodically check to see whether a Ctrl-C or SIGTERM has
	been received.  This is performed via use of the QUIT macro in
	GDB's code.  QUIT is defined to invoke maybe_quit(), which will be
	periodically called during any lengthy operation.  This is supposed to
	ensure that the user won't have to wait too long for a Ctrl-C or
	SIGTERM to be acted upon.

	When a Ctrl-C / SIGINT is received, quit_handler() will decide whether
	to pass the SIGINT onto the inferior or to call quit() which causes
	gdb_exception_quit to be thrown.  This exception (usually) propagates
	to the top level.  Control is then returned to the top level event
	loop.

	At the moment, SIGTERM is handled very differently.  Instead of
	throwing an exception, quit_force() is called.  This does eventually
	cause GDB to exit(), but prior to that happening, the inferiors
	are killed or detached and other target related cleanup occurs.
	As shown in this discussion between Pedro Alves and myself...

	https://sourceware.org/pipermail/gdb-patches/2021-July/180802.html
	https://sourceware.org/pipermail/gdb-patches/2021-July/180902.html
	https://sourceware.org/pipermail/gdb-patches/2021-July/180903.html

	...we found that it is possible for inferior_ptid and current_thread_
	to get out of sync.  When that happens, the "current_thread_ != nullptr"
	assertion in inferior_thread() can fail resulting in a GDB internal
	error.

	Pedro recommended that we "let the normal quit exception propagate all
	the way to the top level, and then have the top level call quit_force
	if sync_quit_force_run is set."  However, after the v2 series for this
	patch set, we tweaked that idea by introducing a new exception for
	handling SIGTERM.

	This commit implements the obvious part of Pedro's suggestion:
	Instead of calling quit_force from quit(), throw_forced_quit() is now
	called instead.  This causes the new exception 'gdb_exception_forced_quit'
	to be thrown.

	At the top level, I changed catch_command_errors() and captured_main()
	to catch gdb_exception_forced_quit and then call quit_force() from the
	catch block.  I also changed start_event_loop() to also catch
	gdb_exception_forced_quit; while we could also call quit_force() from
	that catch block, it's sufficient to simply rethrow the exception
	since it'll be caught by the newly added code in captured_main().

	Making these changes fixed the failure / regression that I was seeing
	for gdb.base/gdb-sigterm.exp when run on a machine with glibc-2.34.
	However, there are many other paths back to the top level which this
	test case does not test.  I did an audit of all of the try / catch
	code in GDB in which calls in the try-block might (eventually) call
	QUIT.  I found many cases where gdb_exception_quit and the new
	gdb_exception_forced_quit will be swallowed.  (When using GDB, have
	you ever hit Ctrl-C and not have it do anything; if so, it could be
	due to a swallowed gdb_exception_quit in one of the cases I've
	identified.)  The rest of the patches in this series deal with this
	concern.

	Introduce gdb_exception_forced_quit
	This commit adds a new exception 'gdb_exception_forced_quit', reason
	code 'REASON_FORCED_QUIT', return mask 'RETURN_MASK_FORCED_QUIT', and
	a wrapper for throwing the exception, throw_forced_quit().

	The addition of this exception plus supporting code will allow us to
	recognize that a SIGTERM has been received by GDB and then propagate
	recognition of that fact to the upper levels of GDB where it can be
	correctly handled.  At the moment, when GDB receives a SIGTERM, it
	will attempt to exit via a series of calls from the QUIT checking
	code.  However, before it can exit, it must do various cleanups, such
	as killing or detaching all inferiors.  Should these cleanups be
	attempted while GDB is executing very low level code, such as reading
	target memory from within ps_xfer_memory(), it can happen that some of
	GDB's state is out of sync with regard to the cleanup code's
	expectations.  In the case just mentioned, it's been observed that
	inferior_ptid and the current_thread_ are not in sync; this triggers
	an assert / internal error.

	This commit only introduces the exception plus supporting machinery;
	changes which use this new exception are in later commits in this

	Fix value chain use-after-free
	Hannes filed a bug showing a crash, where a pretty-printer written in
	Python could cause a use-after-free.  He sent a patch, but I thought a
	different approach was needed.

	In a much earlier patch (see bug #12533), we changed the Python code
	to release new values from the value chain when constructing a
	gdb.Value.  The rationale for this is that if you write a command that
	does a lot of computations in a loop, all the values will be kept live
	by the value chain, resulting in gdb using a large amount of memory.

	However, suppose a value is passed to Python from some code in gdb
	that needs to use the value after the call into Python.  In this
	scenario, value_to_value_object will still release the value -- and
	because gdb code doesn't generally keep strong references to values (a
	consequence of the ancient decision to use the value chain to avoid
	memory management), this will result in a use-after-free.

	This scenario can happen, as it turns out, when a value is passed to
	Python for pretty-printing.  Now, normally this route boxes the value
	via value_to_value_object_no_release, avoiding the problematic release
	from the value chain.  However, if you then call Value.cast, the
	underlying value API might return the same value, when is then
	released from the chain.

	This patch fixes the problem by changing how value boxing is done.
	value_to_value_object no longer removes a value from the chain.
	Instead, every spot in gdb that might construct new values uses a
	scoped_value_mark to ensure that the requirements of bug #12533 are
	met.  And, because incoming values aren't ever released from the chain
	(the Value.cast one comes earlier on the chain than the
	scoped_value_mark), the bug can no longer occur.  (Note that many
	spots in the Python layer already take this approach, so not many
	places needed to be touched.)

	In the future I think we should replace the use of raw "value *" with
	value_ref_ptr pretty much everywhere.  This will ensure lifetime
	safety throughout gdb.

	The test case in this patch comes from Hannes' original patch.  I only
	made a trivial ("require") change to it.  However, while this fails
	for him, I can't make it fail on this machine; nevertheless, he tried
	my patch and reported the bug as being fixed.

	all-stop "follow-fork parent" and selecting another thread
	With:

	 - catch a fork in thread 1
	 - select thread 2
	 - set follow-fork child
	 - next

	... follow_fork notices that thread 1 had last stopped for a fork
	which hasn't been followed yet, and because thread 1 is not the
	current thread, GDB aborts the execution command, presenting the stop
	in thread 1.

	That makes sense, as only the forking thread (thread 1) survives in
	the child, so better stop and let the user decide how to proceed.

	However, with:

	 - catch a fork in thread 1
	 - select thread 2
	 - set follow-fork parent << note difference here
	 - next

	... GDB does the same: follow_fork notices that thread 1 had last
	stopped for a fork which hasn't been followed yet, and because thread
	1 is not the current thread, GDB aborts the execution command,
	presenting the stop in thread 1.

	Aborting/stopping in this case doesn't make sense to me.  As we're
	following the parent, thread 2 will still continue to exist in the
	parent.  What the child does after we've followed the parent shouldn't
	matter -- it can go on running free, be detached, etc., depending on
	"set schedule-multiple", "set detach-on-fork", etc.  That does not
	influence the execution command that the user issued for the parent
	thread.

	So this patch changes GDB in that direction -- in follow_fork, if
	following the parent, and we've switched threads meanwhile, switch
	back to the unfollowed thread, follow it (stay with the parent), and
	don't abort/stop.  If we're following a fork (as opposed to vfork),
	then switch back again to the thread that the user was trying to
	resume.  If following a vfork, however, stay with the vforking-thread
	selected, as we will need to see a vfork_done event first, before we
	can resume any other thread.

	As I was working on this, I managed to end up calling target_resume
	for a solo-thread resume (to collect the vfork_done event), with
	scope_ptid pointing at the vfork parent thread, and inferior_ptid
	pointing to the vfork child.  For a solo-thread resume, the scope_ptid
	argument to target_resume must the same as inferior_ptid.  The mistake
	was caught by the assertion in target_resume, like so:

	...
	  [infrun] resume_1: step=0, signal=GDB_SIGNAL_0, trap_expected=0, current thread [1722839.1722839.0] at 0x5555555553c3
	  [infrun] do_target_resume: resume_ptid=1722839.1722939.0, step=0, sig=GDB_SIGNAL_0
	../../src/gdb/target.c:2661: internal-error: target_resume: Assertion `inferior_ptid.matches (scope_ptid)' failed.
	...

	but I think it doesn't hurt to catch such a mistake earlier, hence the
	change in internal_resume_ptid.

	Make follow_fork not rely on get_last_target_status
	Currently, if

	  - you're in all-stop mode,
	  - the inferior last stopped because of a fork catchpoint,

	when you next resume the program, gdb checks whether it had last
	stopped for a fork/vfork, and if so,

	 a) if the current thread is the one that forked, gdb follows the
	   parent/child, depending on "set follow-fork" mode.

	 b) if the current thread is some other thread (because you switched
	   threads meanwhile), gdb switches back to that thread, gdb follows
	   the parent/child, and stops the resumption command.

	There's a problem in b), however -- if you have "set schedule-multiple
	off", which is the default, or "set scheduler-locking on", gdb will
	still switch back to the forking thread, even if you didn't want to
	resume it.  For example, with:

	  (gdb) catch fork
	  (gdb) c
	  * thread 1 stops for fork
	  (gdb) thread 2
	  (gdb) set scheduler-locking on
	  (gdb) c

	gdb switches back to thread 1, and follows the fork.

	Or with:

	  (gdb) add-inferior -exec prog
	  (gdb) inferior 2
	  (gdb) start
	  (gdb) inferior 1
	  (gdb) catch fork
	  (gdb) c
	  * thread 1.1 stops for fork
	  (gdb) inferior 2
	  (gdb) set schedule-multiple off # this is the default
	  (gdb) c

	gdb switches back to thread 1.1, and follows the fork.

	Another issue is that, because follow_fork relies on
	get_last_target_status to find the thread that has a pending fork, it
	is possible to confuse it.  For example, "run" or "start" call
	init_wait_for_inferior, which clears the last target status, so this:

	  (gdb) catch fork
	  (gdb) c
	  * thread 1 stops for fork
	  (gdb) add-inferior -exec prog
	  (gdb) inferior 2
	  (gdb) start
	  (gdb) set follow-fork child
	  (gdb) inferior 1
	  (gdb) n

	... does not follow to the fork child of inferior 1, because the
	get_last_target_status call in follow_fork doesn't return a
	TARGET_WAITKIND_FORKED.  Thanks to Simon for this example.

	All of the above are fixed by this patch.  It changes follow_fork to
	not look at get_last_target_status, but to instead iterate over the
	set of threads that the user is resuming, and find the one that has a
	pending_follow kind of fork/vfork.

	gdb.base/foll-fork.exp is augmented to exercise the last "start"
	scenario described above.  The other cases will be exercised in the
	testcase added by the following patch.

	Improve "info program"
	With gdb.base/catch-follow-exec.exp, we currently see:

	~~~~~~~~~~~~~~~
	 (gdb)
	 continue
	 Continuing.
	 process 693251 is executing new program: /usr/bin/ls
	 [New inferior 2]
	 [New process 693251]
	 [Switching to process 693251]

	 Thread 2.1 "ls" hit Catchpoint 2 (exec'd /usr/bin/ls), 0x00007ffff7fd0100 in _start () from /lib64/ld-linux-x86-64.so.2
	 (gdb)
	 info prog
	 No selected thread.
	~~~~~~~~~~~~~~~

	Note the "No selected thread" output.  That is totally bogus, because
	there _is_ a selected thread.  What GDB really means, is that it can't
	find the thread that had the latest (user-visible) stop.  And that
	happens because "info program" gets that info from
	get_last_target_status, and the last target status has been cleared.

	However, GDB also checks if there is a selected thread, here:

	  if (ptid == null_ptid || ptid == minus_one_ptid)
	    error (_("No selected thread."));

	.. the null_ptid part.  That is also bogus, because what matters is
	the thread that last reported a stop, not the current thread:

	 - in all-stop mode, "info program" displays info about the last stop.
	   That may have happened on a thread different from the selected
	   thread.

	 - in non-stop mode, because all threads are controlled individually,
	   "info program" shows info about the last stop of the selected
	   thread.

	The current code already behaves this way, though in a poor way.  This
	patch reimplements it, such that the all-stop version now finds the
	thread that last reported an event via the 'previous_thread' strong
	reference.  Being a strong reference means that if that thread has
	exited since the event was reported, 'previous_thread' will still
	point to it, so we can say that the thread exited meanwhile.

	The patch also extends "info program" output a little, to let the user
	know which thread we are printing info for.  For example, for the
	gdb.base/catch-follow-exec.exp case we shown above, we now get:

	 (gdb) info prog
	 Last stopped for thread 2.1 (process 710867).
		 Using the running image of child process 710867.
	 Program stopped at 0x7ffff7fd0100.
	 It stopped at breakpoint 2.
	 Type "info stack" or "info registers" for more information.
	 (gdb)

	while in non-stop mode, we get:

	 (gdb) info prog
	 Selected thread 2.1 (process 710867).
		 Using the running image of child process 710867.
	 Program stopped at 0x7ffff7fd0100.
	 It stopped at breakpoint 2.
	 Type "info stack" or "info registers" for more information.
	 (gdb)

	In both cases, the first line of output is new.

	The existing code considered these running/exited cases as an error,
	but I think that that's incorrect, since this is IMO just plain
	execution info as well.  So the patch makes those cases regular
	prints, not errors.

	If the thread is running, we get, in non-stop mode:

	 (gdb) info prog
	 Selected thread 2.1 (process 710867).
	 Selected thread is running.

	... and in all-stop:

	 (gdb) info prog
	 Last stopped for thread 2.1 (process 710867).
	 Thread is now running.

	If the thread has exited, we get, in non-stop mode:

	 (gdb) info prog
	 Selected thread 2.1 (process 710867).
	 Selected thread has exited.

	... and in all-stop:

	 (gdb) info prog
	 Last stopped for thread 2.1 (process 710867).
	 Thread has since exited.

	The gdb.base/info-program.exp testcase was much extended to test
	all-stop/non-stop and single-threaded/multi-threaded.

	Convert previous_inferior_ptid to strong reference to thread_info
	I originally wrote this patch, because while working on some other
	patch, I spotted a regression in the
	gdb.multi/multi-target-no-resumed.exp.exp testcase.  Debugging the
	issue, I realized that the problem was related to how I was using
	previous_inferior_ptid to look up the thread the user had last
	selected.  The problem is that previous_inferior_ptid alone doesn't
	tell you which target that ptid is from, and I was just always using
	the current target, which was incorrect.  Two different targets may
	have threads with the same ptid.

	I decided to fix this by replacing previous_inferior_ptid with a
	strong reference to the thread, called previous_thread.

	I have since found a new motivation for this change -- I would like to
	tweak "info program" to not rely on get_last_target_status returning a
	ptid that still exists in the thread list.  With both the follow_fork
	changes later in this series, and the step-over-thread-exit changes,
	that can happen, as we'll delete threads and not clear the last
	waitstatus.

	A new update_previous_thread function is added that can be used to
	update previous_thread from inferior_ptid.  This must be called in
	several places that really want to get rid of previous_thread thread,
	and reset the thread id counter, otherwise we get regressions like
	these:

	  (gdb) info threads -gid

	I.e., GDB was failing to restart the thread counter back to 1, because
	the previous_thread thread was being help due to the strong reference.

	Tweak "Using the running image of ..." output
	Currently, "info files" and "info program" on a few native targets
	show:

	 (gdb) info files
	 Symbols from "/home/pedro/gdb/tests/threads".
	 Native process:
		 Using the running image of child Thread 0x7ffff7d89740 (LWP 1097968).
						  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
	 ...

	 (gdb) info program
		 Using the running image of child Thread 0x7ffff7d89740 (LWP 1097968).
						  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
	 Program stopped at 0x555555555278.
	 ...


	This patch changes them to:

	 (gdb) info files
	 Symbols from "/home/pedro/gdb/tests/threads".
	 Native process:
		 Using the running image of child process 1097968.
		                                  ^^^^^^^^^^^^^^^
	 ...

	 (gdb) info program
		 Using the running image of child process 1097968.
		                                  ^^^^^^^^^^^^^^^
	 Program stopped at 0x555555555278.
	 ...


	... which I think makes a lot more sense in this context.  The "info
	program" manual entry even says:

	  "Display information about the status of your program: whether it is
	   running or not, what process it is, and why it stopped."
	                        ^^^^^^^^^^^^^

	This change affects ptrace targets, procfs targets, and Windows.

	gdb: split gdbarch component types to gdbarch_types.py
	Editing gdbarch-components.py is not an experience in an editor that is
	minimally smart about Python.  Because gdbarch-components.py is read and
	exec'd by gdbarch.py, it doesn't import the  Info / Method / Function /
	Value types.  And because these types are defined in gdbarch.py, it
	can't import them, as that would make a cyclic dependency.

	Solve this by introducing a third file, gdbarch_types.py, to define
	these types.  Make gdbarch.py and gdbarch-components.py import it.
	Also, replace the read & exec of gdbarch-components.py by a regular
	import.  For this to work though, gdbarch-components.py needs to be
	renamed to gdbarch_components.py.

	gdb: pyproject.toml: set pyright typeCheckingMode = "strict"
	While working on other projects, I found the pyright type checker very
	helpful when editing Python code.  I don't think I have to explain the
	advantages of type checking to a crowd used to C/C++.

	Setting typeCheckingMode to "strict" makes pyright flag a bit more type
	issues than the default of "basic".

	gdb: gdbarch.py: remove Info.__init__
	Info.__init__ currently assigns `self.predicate = None`.  This was
	helpful to ensure that all component types had a `predicate` attribute.
	The generator code could then avoid having code like "if the component
	is anything but Info, use predicate".  Since the previous commit, all
	component types have a predicate attribute which defaults to False.  We
	can therefore remove the assignment in Info.__init__, and in turn remove
	Info.__init__.  We however need to make the printer parameter of
	_Component.__init__ optional, as Info don't need a printer.

	gdb: gdbarch.py: spell out parameters of _Component.__init__
	The way _Component uses kwargs is handy to save a few characters, but it
	doesn't play well with static analysis.  When editing gdbarch.py, my
	editor (which uses pylance under the hood) knows nothing about the
	properties of components.  So it's full of squiggly lines, and typing
	analysis (which I find really helpful) doesn't work.  I therefore think
	it would be better to spell out the parameters.

	gdb: remove invalid / dead code from gdbarch.py
	My editor flagged that the variable `c` (in the lines removed by this
	patch) was unknown.  I guess it ends up working because there is a `c`
	variable in the global scope.  I tried putting `assert False` inside
	that if, and it is not hit, showing that we never enter this if.  So,
	remove it.  There is no change in the generated files.

	Fix crash with "finish" in Rust
	PR rust/30090 points out that a certain "finish" in a Rust program
	will cause gdb to crash.  This happens due to some confusion about
	field indices in rust_language::print_enum.  The fix is to use
	value_primitive_field so that the correct type can be passed; other
	spots in rust-lang.c already do this.

	Note that the enclosed test case comes with an xfail.  This is needed
	because for this function, rustc doesn't follow the platform ABI.

	Handle range types in ax-gdb.c
	A range type can usually be treated the same as its underlying integer
	type, at least for the purposes of agent expressions.  This patch
	arranges for range types to be handled this way in ax-gdb.c, letting a
	somewhat larger subset of Ada expressions be compiled.

2023-02-27  Tom Tromey  <tromey@adacore.com>

	Implement some agent expressions for Ada
	Ada historically has not implemented agent expressions, and some Ada
	constructs probably cannot reasonably be converted to agent
	expressions.  However, a subset of simple operations can be, and this
	patch represents a first step in that direction.

	On one internal AdaCore test case, this improves the performance of a
	conditional breakpoint from 5 minutes to 5 seconds.

	The main tricky part in this patch is ensuring the converted
	expressions detect the cases that will not work.  This is done by
	examining the code in the corresponding evaluation methods.

	Regenerate Linux syscall group info
	This commit makes use of the new script to regenerate the Linux
	syscall group info against strace git hash
	e88e5e9ae6da68f22d15f9be3193b1412ac9aa02.

	Like so:

	 $ cd gdb/syscalls/
	 $ ./update-linux-defaults.sh ~/strace.git/
	 Generating linux-defaults.xml.in
	 $ make
	 for f in aarch64-linux.xml amd64-linux.xml arm-linux.xml bfin-linux.xml \
	          i386-linux.xml mips-n32-linux.xml mips-n64-linux.xml \
		  mips-o32-linux.xml ppc64-linux.xml ppc-linux.xml s390-linux.xml \
		  s390x-linux.xml sparc64-linux.xml sparc-linux.xml; do \
	   xsltproc --output $f apply-defaults.xsl $f.in; \
	 done

	The result is that a lot more syscalls end up assigned to groups.
	Some lose their group info, but that just mirrors what strace does.

	The gdb/syscalls/linux-defaults.xml.in file shows a large diff because
	the new version is ASCII sorted, while the current version was
	somewhat (but not consistently) sorted by "family" of syscalls.

	If I sort the old file and diff against the new, the difference is
	like this:

	Autogenerate gdb/syscalls/linux-defaults.xml.in (groups) from strace sources
	I noticed that "catch syscall group:process" doesn't catch clone3,
	while it does catch clone.

	The catch syscall group information is recorded in the
	gdb/syscalls/linux-defaults.xml.in file, which says:

	  <!-- The group field information was based on strace.  -->

	So I looked at the strace sources, to confirm that clone3 is in fact
	recorded in the "process" group there too, and to check what other
	syscalls might be missing groups.

	After some digging, I found that strace records the group info in C
	arrays, with entries like:
	...
	[ 61] = { 4,	TP,		SEN(wait4),			"wait4"			},
	[ 62] = { 2,	TS|TP,		SEN(kill),			"kill"			},
	[ 63] = { 1,	0,		SEN(uname),			"uname"			},
	...

	You can see the current master's table for Linux x86-64 here:

	  https://github.com/strace/strace/blob/e88e5e9ae6da68f22d15f9be3193b1412ac9aa02/src/linux/x86_64/syscallent.h

	The column with TS|TP above is what defines each syscall's groups.  So
	I wrote a script that extracts this information and generates
	linux-defaults.xml.in.

	gdb: don't treat empty enums as flag enums
	In C++ it is possible to use an empty enum as a strong typedef.  For
	example, a user could write:

	  enum class my_type : unsigned char {};

	Now my_type can be used like 'unsigned char' except the compiler will
	not allow implicit conversion too and from the native 'unsigned char'
	type.

	This is used in the standard library for things like std::byte.

	Currently, when GDB prints a value of type my_type, it looks like
	this:

	  (gdb) print my_var
	  $1 = (unknown: 0x4)

	Which isn't great.  This gets worse when we consider something like:

	  std::vector<my_type> vec;

	When using a pretty-printer, this could look like this:

	  std::vector of length 2, capacity 2 = {(unknown: 0x2), (unknown: 0x4)}

	Clearly not great.  This is described in PR gdb/30148.

	The problem here is in dwarf2/read.c, we assume all enums are flag
	enums unless we find an enumerator with a non-flag like value.
	Clearly an empty enum contains no non-flag values, so we assume the
	enum is a flag enum.

	I propose adding an extra check here; that is, an empty enum should
	never be a flag enum.

	With this the above cases look more like:

	  (gdb) print my_var
	  $1 = 4

	and:

	  std::vector of length 2, capacity 2 = {2, 4}

	Which look much better.

	gdb/testsuite: Improve testing of GDB's completion functions
	When looking at some failures of gdb.linespec/cp-completion-aliases.exp,
	I noticed that when a completion test will fail, it always fails with a
	timeout.  This is because most completion tests use gdb_test_multiple
	and only add a check for the correct output.  This commit adds new
	options for both, tab and command completion.

	For command completion, the new option will check if the prompt was
	printed, and fail in this case. This is enough to know that the test has
	failed because the check comes after the PASS path. For tab completion,
	we have to check if GDB outputted more than just the input line, because
	sometimes GDB would have printed a partial line before finishing with
	the correct completion.

	Remove struct buffer
	I've long wanted to remove 'struct buffer', and thanks to Simon's
	earlier patch, I was finally able to do so.  My feeling has been that
	gdb already has several decent structures available for growing
	strings: std::string of course, but also obstack and even objalloc
	from BFD and dyn-string from libiberty.  The previous patches in this
	series removed all the uses of struct buffer, so this one can remove
	the code and the remaining #includes.

	Don't use struct buffer in top.c
	This changes top.c to use std::string rather than struct buffer.  Like
	the event-top.c change, this is not completely ideal in that it
	requires a copy of the string.

	Don't use struct buffer in event-top.c
	This changes event-top.c to use std::string rather than struct buffer.
	This isn't completely ideal, in that it requires a copy of the string
	to be made.

	Don't use struct buffer in handle_qxfer_threads
	This changes handle_qxfer_threads, in gdbserver, to use std::string
	rather than struct buffer.

	Don't use struct buffer in handle_qxfer_btrace
	This changes handle_qxfer_btrace and handle_qxfer_btrace_conf, in
	gdbserver, to use std::string rather than struct buffer.

	Don't use struct buffer in handle_qxfer_traceframe_info
	This changes handle_qxfer_traceframe_info, in gdbserver, to use
	std::string rather than struct buffer.

	Remove struct buffer from tracefile-tfile.c
	This changes tracefile-tfile.c to use std::string rather than struct

	Write the DWARF index in the background
	The new DWARF cooked indexer interacts poorly with the DWARF index
	cache.  In particular, the cache will require gdb to wait for the
	cooked index to be finalized.  As this happens in the foreground, it
	means that users with this setting enabled will see a slowdown.

	This patch changes gdb to write the cache entry a worker thread.  (As
	usual, in the absence of threads, this work is simply done immediately
	in the main thread.)

	Some care is taken to ensure that this can't crash, and that gdb will
	not exit before the task is complete.

	To avoid use-after-free problems, the DWARF per-BFD object explicitly
	waits for the index cache task to complete.

	To avoid gdb exiting early, an exit observer is used to wait for all
	such pending tasks.

	In normal use, neither of these waits will be very visible.  For users
	using "-batch" to pre-generate the index, though, it would be.
	However I don't think there is much to be done about this, as it was
	the status quo ante.

2023-02-24  Tom Tromey  <tromey@adacore.com>

	Only use the per-BFD object to write a DWARF index
	The DWARF index does not need access to the objfile or per-objfile
	objects when writing -- it's entirely based on the objfile-independent
	per-BFD data.

	This patch implements this idea by changing the entire API to only be
	passed the per-BFD object.  This simplifies some lifetime reasoning
	for the next patch.

	This patch removes some code that ensures that the BFD came from a
	file.  It seems to me that checking for the existence of a build-id is
	good enough for the index cache.

	x86: allow to request ModR/M encoding
	Several insns have a (typically shorter) non-ModR/M and a (typically
	longer) ModR/M encoding. In most cases the former is used by default.
	This isn't too dissimilar from register-only insns sometimes having two
	encoding forms. In those cases {load} or {store} can be used to control
	the encoding used. Extend this to ModR/M-less encodings which have a
	ModR/M counterpart (note that BSWAP hasn't). For insn reading and
	writing their (explicit) memory operand, both prefixes are honored;
	otherwise only the applicable one is.

	Note that for some forms of XCHG, {store} has already been performing
	this function, apparently as an unnoticed side effect of adding D to
	the template.

	best confusing. An extreme example would be the two rotate-through-carry
	insns, where a negative value would _not_ mean rotating the
	corresponding number of bits in the other direction. To refuse such,
	give meaning to the combination of Imm8 and Imm8S in templates (so far
	these weren't used together anywhere). The issue was with
	smallest_imm_type() blindly setting .imm8 for signed numbers determined
	to fit in a byte.

	VPROT{B,W,D,Q} is a little special: The rotate count there is a signed
	quantity, so Imm8 is replaced by Imm8S. Adjust affected testcases
	accordingly as well.

	Another small adjustment to the testsuite is necessary: AAM and AAD were
	never sensible to use with 0xffffff90 operands. This should have been an
	error.

	gdb: remove --disable-gdbmi configure option
	I noticed that the --disable-gdbmi option was broken for almost a year
	(since 740b42ceb7c "gdb/python/mi: create MI commands using python").

	The problem today is the python/py-cmd.c file.  It is included in the
	build if Python support is enabled, and it calls into some MI functions
	(e.g. insert_mi_cmd_entry).  If MI support is disabled, we get some
	undefined symbols like:

	    mold: error: undefined symbol: insert_mi_cmd_entry(std::unique_ptr<mi_command, std::default_delete<mi_command> >)
	    >>> referenced by py-micmd.c
	    >>>               python/py-micmd.o:(micmdpy_install_command(micmdpy_object*))

	The python/py-cmd.c file should be included in the build if both Python
	and MI support are enabled.  It is not a case we support today, but it
	could be done with a bit more configure code.  However, I think we
	should just remove the --disable-gdbmi option, and just include MI
	support unconditionally.

	Tom Tromey proposed a while ago to remove this option, but it ended
	staying:

	  https://inbox.sourceware.org/gdb-patches/20180628172132.28843-1-tom@tromey.com/

	However, there was no strong opposition to remove it.  The argument was
	just "bah, it doesn't hurt anybody".

	But given today's case, I would rather remove complexity rather than add
	some.  I couldn't find anybody caring deeply for that option, and it's
	not like MI adds any external dependency.  It's just a bit more code.

	Removing the option will not break anybody using --disable-gdbmi (it can
	be found in many build scripts [1]), since we don't flag invalid
	configure flags.

	So, remove the option from configure.ac, and adjust Makefile.in
	accordingly to always include the MI objects in the build.

	gdb.reverse/time-reverse.exp: test both time syscall and C time function
	Instead of only testing this on systems that have a SYS_time syscall,
	test it everywhere using the time(2) C function, and in addition, run
	the tests again using the SYS_time syscall.

	The C variant ensures that if some platform uses some syscall we are
	not aware of yet, we'll still exercise it, and likely fail, at which
	point we should teach GDB about the syscall.

	The explicit syscall variant is useful on platforms where the C
	function does not call a syscall at all by default, e.g., on some
	systems the C time function wraps an implementation provided by the
	vDSO.

	gdb: add --with-curses to --configuration output
	'gdb --configuration' does not mention if GDB was built with curses.
	Since b5075fb68d4 (Rename to allow_tui_tests, 2023-01-08) it does show
	--enable-tui (or --disable-tui), but one might want to know if GDB was
	built with curses independently of the availability of the TUI.

	Since configure.ac uses AC_SEARCH_LIBS to check for the curses library,
	we do not get an automatically defined HAVE_LIBCURSES symbol in
	config.in. We do have symbols defined by AC_CHECK_HEADERS
	(HAVE_CURSES_H, etc.) but it would be cumbersome to use those in
	print_gdb_configuration because we would have to check for all 6 symbols
	corresponding the 6 headers listed. This would also increase the
	maintenance burden if support for other variations of curses are added.

	Instead, define 'HAVE_LIBCURSES' ourselves by adding an
	'action-if-found' argument to AC_SEARCH_LIBS, and use it in
	print_gdb_configuration.

	While at it, remove the condition on 'ac_cv_search_waddstr' and set
	'curses_found' directly in 'action-if-found'.

	gas/testsuite: adjust a test for case insensitive file systems
	When dealing with case insensitive file systems, ".file line.s" and
	".file Line.s" are identical and thus gas won't change the current
	input file.
	However, in line.l test, it's expecting to trigger an input file switch.
	As the second filename doesn't matter in it, change it to fit for those
	file systems.

	[aarch64] Enable pointer authentication support for aarch64 bare metal/kernel mode addresses
	At the moment GDB only handles pointer authentication (pauth) for userspace
	addresses and if we're debugging a Linux-hosted program.

	The Linux Kernel can be configured to use pauth instructions for some
	additional security hardening, but GDB doesn't handle this well.

	To overcome this limitation, GDB needs a couple things:

	1 - The target needs to advertise pauth support.
	2 - The hook to remove non-address bits from a pointer needs to be registered
	    in aarch64-tdep.c as opposed to aarch64-linux-tdep.c.

	There is a patch for QEMU that addresses the first point, and it makes
	QEMU's gdbstub expose a couple more pauth mask registers, so overall we will
	have up to 4 pauth masks (2 masks or 4 masks):

	pauth_dmask
	pauth_cmask
	pauth_dmask_high
	pauth_cmask_high

	pauth_dmask and pauth_cmask are the masks used to remove pauth signatures
	from userspace addresses. pauth_dmask_high and pauth_cmask_high masks are used
	to remove pauth signatures from kernel addresses.

	The second point is easily addressed by moving code around.

	When debugging a Linux Kernel built with pauth with an unpatched GDB, we get
	the following backtrace:

	 #0  __fput (file=0xffff0000c17a6400) at /repos/linux/fs/file_table.c:296
	 #1  0xffff8000082bd1f0 in ____fput (work=<optimized out>) at /repos/linux/fs/file_table.c:348

	 #3  0x30d48000080ade30 in ?? ()
	 Backtrace stopped: previous frame identical to this frame (corrupt stack?)

	With a patched GDB, we get something a lot more meaningful:

	 #0  __fput (file=0xffff0000c1bcfa00) at /repos/linux/fs/file_table.c:296
	 #1  0xffff8000082bd1f0 in ____fput (work=<optimized out>) at /repos/linux/fs/file_table.c:348

	gdb/doc: Consistency fixes for GDB/MI documentation
	I noticed two inconsistencies in the GDB/MI documentation, which this
	commit addresses:

	  1. Each MI command is introduced like this:

	     @subheading The @code{-command-name} Command

	     Except for a few of the tracing command, which just use:

	     @subheading -command-name

	     In this commit I've updated all these trace commands to use the
	     more common format.

	  2. Each MI command starts with a @subheading, and then the details
	     of that command are split up using multiple @subsubheading
	     entries.

	     Except for a few commands which use @subheading for the top-level
	     command, and then continue to use @subheading for each part of
	     the command description.

	     In this commit I've updated these to use @subsubheading where
	     appropriate.

	[gdb/symtab] Trust epilogue unwind info for unknown or non-gcc producer
	Currently we only trust epilogue unwind info only for gcc >= 4.5.0.

	This has the effect that we don't trust epilogue unwind info for:
	- unknown producers (CU without DW_AT_producer attribute)
	- non-gcc producers (say, clang).

	Instead, only distrust epilogue unwind info only for gcc < 4.5.0.

2023-02-20  Tom de Vries  <tdevries@suse.de>

	[gdb/symtab] Trust epilogue unwind info for unknown producer (-g0 case)
	For a -g0 -fasynchronous-unwind-tables exec (without .debug_info but with
	.eh_frame section), start using the dwarf2 unwinder instead of the
	"amd64 epilogue override" unwinder, by returning true in
	compunit_epilogue_unwind_valid for cust == nullptr.

	This has effect both on the amd64 and i386 targets, but only add amd64
	test-case gdb.base/unwind-on-each-insn-amd64-2.exp.

2023-02-20  Tom de Vries  <tdevries@suse.de>

	[gdb/tdep] Add amd64/i386 epilogue override unwinders
	For amd64 the current frame-unwinders are:
	...
	$ gdb -q -batch -ex "set arch i386:x86-64" -ex "maint info frame-unwinders"
	The target architecture is set to "i386:x86-64".
	dummy                   DUMMY_FRAME
	dwarf2 tailcall         TAILCALL_FRAME
	inline                  INLINE_FRAME
	python                  NORMAL_FRAME
	amd64 epilogue          NORMAL_FRAME
	dwarf2                  NORMAL_FRAME
	dwarf2 signal           SIGTRAMP_FRAME
	amd64 sigtramp          SIGTRAMP_FRAME
	amd64 prologue          NORMAL_FRAME
	...

	For a -g0 -fasynchronous-unwind-tables exec (without .debug_info but with
	.eh_frame section), we'd like to start using the dwarf2 unwinder instead of
	the "amd64 epilogue" unwinder, by returning true in
	compunit_epilogue_unwind_valid for cust == nullptr.

	But we'd run into the following problem for a -g0
	-fno-asynchronous-unwind-tables (without .debug_info and .eh_frame section)
	exec:
	- the "amd64 epilogue" unwinder would not run
	  (because compunit_epilogue_unwind_valid () == true)
	- the dwarf2 unwinder would also not run
	  (because there's no .eh_frame info).

	Fix this by:
	- renaming the "amd64 epilogue" unwinder to "amd64 epilogue override", and
	- adding a fallback "amd64 epilogue" after the dwarf unwinders,
	while making sure that only one of the two is active.  Likewise for i386.  NFC.

	For amd64, this results in this change:
	...
	 $ gdb -q -batch -ex "set arch i386:x86-64" -ex "maint info frame-unwinders"
	 The target architecture is set to "i386:x86-64".
	 dummy                   DUMMY_FRAME
	 dwarf2 tailcall         TAILCALL_FRAME
	 inline                  INLINE_FRAME
	 python                  NORMAL_FRAME
	-amd64 epilogue          NORMAL_FRAME
	+amd64 epilogue override NORMAL_FRAME
	 dwarf2                  NORMAL_FRAME
	 dwarf2 signal           SIGTRAMP_FRAME
	+amd64 epilogue          NORMAL_FRAME
	 amd64 sigtramp          SIGTRAMP_FRAME
	 amd64 prologue          NORMAL_FRAME
	...

	And for i386:
	...
	 $ gdb -q -batch -ex "set arch i386" -ex "maint info frame-unwinders"
	 The target architecture is set to "i386".
	 dummy                   DUMMY_FRAME
	 dwarf2 tailcall         TAILCALL_FRAME
	 iline                  INLINE_FRAME
	-i386 epilogue           NORMAL_FRAME

	Since commit 9af467b8240 ("[gdb/testsuite] Fix gdb.threads/schedlock.exp on
	fast cpu"), the test-case fails for gcc 4.8.5.

	The problem is that for gcc 4.8.5, the commit turned a two-line loop:
	...
	(gdb) next
	78          while (*myp > 0)
	(gdb) next
	81              MAYBE_CALL_SOME_FUNCTION(); (*myp) ++;
	(gdb) next
	78          while (*myp > 0)
	...
	into a three-line loop:
	...
	(gdb) next
	83              MAYBE_CALL_SOME_FUNCTION(); (*myp) ++;
	(gdb) next
	84              cnt++;
	(gdb) next

	(gdb) next
	83              MAYBE_CALL_SOME_FUNCTION(); (*myp) ++;
	(gdb)
	...
	and the test-case doesn't expect this.

	Fix this by reverting back to the original loop shape as much as possible by:
	- removing the cnt++ line
	- replacing "while (1)" with "while (one)", where one is a volatile variable
	  set to 1.

	Tested on x86_64-linux, using compilers:

	Fix "start" for D, Rust, etc
	The new DWARF indexer broke "start" for some languages.

	For D, it is broken because, while the code in cooked_index_shard::add
	specifically excludes Ada, it fails to exclude D.  This means that the
	C "main" will be detected as "main" here -- whereas what is intended
	is for the code in find_main_name to use d_main_name to find the name.

	The Rust compiler, on the other hand, uses DW_AT_main_subprogram.
	However, the code in dwarf2_build_psymtabs_hard fails to create a
	fully-qualified name, so the name always ends up as plain "main".

	For D and Ada, a very simple approach suffices: remove the check
	against "main" from cooked_index_shard::add.  This also has the
	benefit of slightly speeding up DWARF indexing.  I assume this
	approach will work for Pascal and Modula-2 as well, but I don't have a
	way to test those at present.

	For Rust, though, this is not sufficient.  And, computing the
	fully-qualified name in dwarf2_build_psymtabs_hard will crash, because
	cooked_index_entry::full_name uses the canonical name -- and that is
	not computed until after canonicalization.

	However, we don't want to wait for canonicalization to be done before
	computing the main name.  That would remove any benefit from doing
	canonicalization is the background.

	This patch solves this dilemma by noticing that languages using
	DW_AT_main_subprogram are, currently, disjoint from languages
	requiring canonicalization.  Because of this, we can add a parameter
	to full_name to let us avoid crashes, slowdowns, and races here.

	This is kind of tricky and ugly, so I've tried to comment it
	sufficiently.

	While doing this, I had to change gdb.dwarf2/main-subprogram.exp.  A
	different possibility here would be to ignore the canonicalization
	needs of C in this situation, because those only affect certain types.
	However, I chose this approach because the test case is artificial
	anyhow.

	A long time ago, in an earlier threading attempt, I changed the global
	current_language to be a function (hidden behind a macro) to let us
	attempt lazily computing the current language.  Perhaps this approach
	could still be made to work.  However, that also seemed rather tricky,
	more so than this patch.

	Fix multi-threaded debugging under AIX
	Multi-threaded debugging using the libpthdebug debug interface
	is currently broken due to multiple issues.

	When debugging a single inferior, we were getting assertion
	failures in get_aix_thread_info as no tp->priv structure was
	allocated for the main thread.

	We fixed this by switching the main
	thread from a (pid, 0, 0) ptid_t to a (pid, 0, tid) ptid_t and
	allocaing the tp->priv structure in sync_threadlists.

	As a result, the switch_to_thread call in pdc_read_data could
	now fail since the main thread no longer uses (pid, 0, 0).

	So we replaced the call by only switching inferior_ptid, the current
	inferior, and the current address space (like proc-service.c).
	Add similar switching to pdc_write_data where it was missing
	completely.

	When debugging multiple inferiors, an additional set of
	problems prevented correct multi-threaded debugging:

	First of all, aix-thread.c used to have a number of global
	variables holding per-inferior information.

	We switched hese
	to a per-inferior data structure instead.

	Also, sync_threadlists was getting confused as we were
	comparing the list of threads returned by libpthdebug
	for *one* process with GDB's list of threads for *all*
	processes. Now we only use he GDB threads of the current
	inferior instead.

	We also skip calling pd_activate
	from pd_enable if that in_initial_library_scan flag is
	true for the current inferior.

	Finally, the presence of the thread library in any but
	the first inferior was not correctly detected due to a
	bug in solib-aix.c, where the BFD file name for shared
	library members was changed when the library was loaded
	for the first time, which caused the library to no longer
	be recognized by name when loaded a second time.

	[gdb/testsuite] Simplify gdb.arch/amd64-disp-step-avx.exp
	On SLE-11, with glibc 2.11.3, I run into:
	...
	(gdb) PASS: gdb.arch/amd64-disp-step-avx.exp: vex3: \
	  var128 has expected value after
	continue^M
	Continuing.^M
	^M
	Program received signal SIGSEGV, Segmentation fault.^M
	0x0000000000400283 in _exit (status=0) at \
	  ../sysdeps/unix/sysv/linux/_exit.c:33^M
	33      ../sysdeps/unix/sysv/linux/_exit.c: No such file or directory.^M
	(gdb) FAIL: gdb.arch/amd64-disp-step-avx.exp: \
	  continue until exit at amd64-disp-step-avx
	...

	This is not related to gdb, we get the same result by just running the exec.

	The problem is that the test-case:
	- calls glibc's _exit, and
	- uses -nostartfiles -static, putting the burden for any necessary
	  initialization for calling glibc's _exit on the test-case itself.

	So, when we get to the second insn in _exit:
	...
	000000000040acb0 <_exit>:
	  40acb0:       48 63 d7                movslq %edi,%rdx
	  40acb3:       64 4c 8b 14 25 00 00    mov    %fs:0x0,%r10
	...
	no glibc-related initialization is done, and we run into the segfault.

	Adding this (borrowed from __libc_start_main) in _start in the .S file is
	sufficient to fix it:
	...
	         .rept 200
	         nop
	+        call __pthread_initialize_minimal
	         .endr
	...
	But that already doesn't compile with say glibc 2.31, and regardless I think
	this sort of fix is too fragile.

	We could of course fix this by simply not running to exit.  But ideally we'd
	have an exec that doesn't segfault when you just run it.

	Alternatively, we could hand-code an _exit syscall and bypass glibc
	all together.  But I'd rather fix this in a way that simplifies the test-case.

	Taking a step back, the -nostartfiles -static was added to address that the
	xmm registers were not zero at main (which AFAICT is a valid thing to happen).

	[ The change itself silently broke the test-case, needing further fixing by
	commit 40310f30a51 ("gdb: make gdb.arch/amd64-disp-step-avx.exp actually test
	displaced stepping"). ]

	Instead, simplify things by reverting to the original situation:
	- no -nostartfiles -static compilation flags,
	- no _start in the .S file,
	- use exit instead of _exit in the .S file,
	and fix the original problem by setting the xmm registers to zero rather than
	checking that they're zero.

	Now that we're no longer forcing -static, add nopie to the flags to prevent
	compilation failure with target board unix/-fPIE/-pie.

	Tested on x86_64-linux.

	The fix is to disable cooperative SIGINT handling while handling
	inferior events, so that SIGINT is saved in the global quit flag, and
	not in the extension language, while handling an event.

	This commit augments the testcase added by the previous commit to test
	this scenario as well.

	Don't throw quit while handling inferior events
	This implements what I suggested here:

	 https://inbox.sourceware.org/gdb-patches/ab97c553-f406-b094-cdf3-ba031fdea925@palves.net/

	Here is the current default quit_handler, a function that ends up
	called by the QUIT macro:

	 void
	 default_quit_handler (void)
	 {
	   if (check_quit_flag ())
	     {
	       if (target_terminal::is_ours ())
	 	quit ();
	       else
	 	target_pass_ctrlc ();
	      }
	 }

	As we can see above, when the inferior is running in the foreground,
	then a Ctrl-C is translated into a call to target_pass_ctrlc().

	The target_terminal::is_ours() case above is there to handle the
	scenario where GDB has the terminal, meaning it is handling some
	command the user typed, like "list", or "p a + b" or some such.

	However, when the inferior is running on the background, say with
	"c&", GDB also has the terminal.  Run control handling is now done in
	the "background".  The CLI is responsive to user commands.  If users
	type Ctrl-C, they're expecting it to interrupt whatever command they
	next type in the CLI, which again, could be "list", "p a + b", etc.
	It's as if background run control was handled by a separate thread,
	and the Ctrl-C is meant to go to the main thread, handling the CLI.

	However, when handling an event, inside fetch_inferior_event &
	friends, a Ctrl-C _also_ results in a Quit exception, from the same
	default_quit_handler function shown above.  This quit aborts run
	control handling, breakpoint condition evaluation, etc., and may even
	leave run control in an inconsistent state.

	The testcase added by this patch illustrates this.  The test program
	just loops a number of times calling the "foo" function.

	The idea is to set a breakpoint in the "foo" function with a condition
	that sends SIGINT to GDB, and then evaluates to false, which results
	in the program being re-resumed in the background.  The SIGINT-sending
	emulates pressing Ctrl-C just while GDB was evaluating the breakpoint
	condition, except, it's more deterministic.

	It looks like this:

	  (gdb) p $counter = 0
	  $1 = 0
	  (gdb) b foo if $counter++ == 10 || $_shell("kill -SIGINT `pidof gdb`") != 0
	  Breakpoint 2 at 0x555555555131: file gdb.base/bg-exec-sigint-bp-cond.c, line 21.
	  (gdb) c&
	  Continuing.
	  (gdb)

	After that background continue, the breakpoint should be hit 10 times,
	and we should see 10 "Quit" being printed on the screen.  As if the
	user typed Ctrl-C on the prompt a number of times with no inferior
	running:

	  (gdb)        <<< Ctrl-C
	  (gdb) Quit   <<< Ctrl-C
	  (gdb) Quit   <<< Ctrl-C
	  (gdb)

	However, here's what you see instead:

	  (gdb) c&
	  Continuing.
	  (gdb) Quit
	  (gdb)

	Just one Quit, and nothing else.  If we look at the thread's state, we see:

	  (gdb) info threads
	    Id   Target Id                                            Frame
	  * 1    Thread 0x7ffff7d6f740 (LWP 112192) "bg-exec-sigint-" foo () at gdb.base/bg-exec-sigint-bp-cond.c:21

	So the thread stopped, but we didn't report a stop...

	Issuing another continue shows the same immediate-and-silent-stop:

	  (gdb) c&
	  Continuing.
	  (gdb) Quit
	  (gdb) p $counter
	  $2 = 2

	As mentioned, since the run control handling, and breakpoint and
	watchpoint evaluation, etc. are running in the background from the
	perspective of the CLI, when users type Ctrl-C in this situation,
	they're thinking of aborting whatever other command they were typing
	or running at the prompt, not the run control side, not the previous
	"c&" command.

	So I think that we should install a custom quit_handler while inside
	fetch_inferior_event, where we already disable pagination and other
	things for a similar reason.  This custom quit handler does nothing if
	GDB has the terminal, and forwards Ctrl-C to the inferior otherwise.

	With the patch implementing that, and the same testcase, here's what
	you see instead:

	 (gdb) p $counter = 0
	 $1 = 0
	 (gdb) b foo if $counter++ == 10 || $_shell("kill -SIGINT `pidof gdb`") != 0
	 Breakpoint 2 at 0x555555555131: file gdb.base/bg-exec-sigint-bp-cond.c, line 21.
	 (gdb) c&
	 Continuing.
	 (gdb) Quit
	 (gdb) Quit
	 (gdb) Quit
	 (gdb) Quit
	 (gdb) Quit
	 (gdb) Quit
	 (gdb) Quit
	 (gdb) Quit
	 (gdb) Quit
	 (gdb) Quit
	 (gdb)
	 Breakpoint 2, foo () at gdb.base/bg-exec-sigint-bp-cond.c:21
	 21        return 0;

	Add new "$_shell(CMD)" internal function
	For testing a following patch, I wanted a way to send a SIGINT to GDB
	from a breakpoint condition.  And I didn't want to do it from a Python
	breakpoint or Python function, as I wanted to exercise non-Python code
	paths.  So I thought I'd add a new $_shell internal function, that
	runs a command under the shell, and returns the exit code.  With this,
	I could write:

	  (gdb) b foo if $_shell("kill -SIGINT $gdb_pid") != 0 || <other condition>

	I think this is generally useful, hence I'm proposing it here.

	Here's the new function in action:

	 (gdb) p $_shell("true")
	 $1 = 0
	 (gdb) p $_shell("false")
	 $2 = 1
	 (gdb) p $_shell("echo hello")
	 hello
	 $3 = 0
	 (gdb) p $_shell("foobar")
	 bash: line 1: foobar: command not found
	 $4 = 127
	 (gdb) help function _shell
	 $_shell - execute a shell command and returns the result.
	 Usage: $_shell (command)
	 Returns the command's exit code: zero on success, non-zero otherwise.
	 (gdb)

	Make "ptype INTERNAL_FUNCTION" in Ada print like other languages
	Currently, printing the type of an internal function in Ada shows
	double <>s, like:

	 (gdb) with language ada -- ptype $_isvoid
	 type = <<internal function>>

	while all other languages print it with a single <>, like:

	 (gdb) with language c -- ptype $_isvoid
	 type = <internal function>

	I don't think there's a reason that Ada needs to be different.  We
	currently print the double <>s because we take this path in
	ada_print_type:

	    switch (type->code ())
	      {
	      default:
		gdb_printf (stream, "<");
		c_print_type (type, "", stream, show, level, language_ada, flags);
		gdb_printf (stream, ">");
		break;

	... and the type's name already has the <>s.

	Fix this by simply adding an early check for
	TYPE_CODE_INTERNAL_FUNCTION.

2023-02-15  Pedro Alves  <pedro@palves.net>

	Fix "ptype INTERNAL_FUNC" (PR gdb/30105)
	Currently, looking at the type of an internal function, like below,
	hits an odd error:

	 (gdb) ptype $_isvoid
	 type = <internal function>type not handled in c_type_print_varspec_prefix()

	That is an error thrown from
	c-typeprint.c:c_type_print_varspec_prefix, where it reads:

	    ...
	    case TYPE_CODE_DECFLOAT:
	    case TYPE_CODE_FIXED_POINT:
	      /* These types need no prefix.  They are listed here so that
		 gcc -Wall will reveal any types that haven't been handled.  */
	      break;
	    default:
	      error (_("type not handled in c_type_print_varspec_prefix()"));
	      break;

	Internal function types have type code TYPE_CODE_INTERNAL_FUNCTION,
	which is not explicitly handled by that switch.

	That comment quoted above says that gcc -Wall will reveal any types
	that haven't been handled, but that's not actually true, at least with
	modern GCCs.  You would need to enable -Wswitch-enum for that, which
	we don't.  If I do enable that warning, then I see that we're missing
	handling for the following type codes:

	   TYPE_CODE_INTERNAL_FUNCTION,
	   TYPE_CODE_MODULE,
	   TYPE_CODE_NAMELIST,
	   TYPE_CODE_XMETHOD

	TYPE_CODE_MODULE and TYPE_CODE_NAMELIST and Fortran-specific, so it'd
	be a little weird to handle them here.

	I tried to reach this code with TYPE_CODE_XMETHOD, but couldn't figure
	out how to.  ptype on an xmethod isn't treated specially, it just
	complains that the method doesn't exist.  I've extended the
	gdb.python/py-xmethods.exp testcase to make sure of that.

	My thinking is that whatever type code we add next, the most likely
	scenario is that it won't need any special handling, so we'd just be
	adding another case to that "do nothing" list.  If we do need special
	casing for whatever type code, I think that tests added at the same
	time as the feature would uncover it anyhow.  If we do miss adding the
	special casing, then it still looks better to me to print the type
	somewhat incompletely than to error out and make it harder for users
	to debug whatever they need.  So I think that the best thing to do
	here is to just remove all those explicit "do nothing" cases, along
	with the error default case.

	After doing that, I decided to write a testcase that iterates over all
	supported languages doing "ptype INTERNAL_FUNC".  That revealed that
	Pascal has a similar problem, except the default case hits a
	gdb_assert instead of an error:

	 (gdb) with language pascal -- ptype $_isvoid
	 type =
	 ../../src/gdb/p-typeprint.c:268: internal-error: type_print_varspec_prefix: unexpected type
	 A problem internal to GDB has been detected,
	 further debugging may prove unreliable.

	That is fixed by this patch in the same way.

	You'll notice that the new testcase special-cases the Ada expected
	output:

		} elseif {$lang == "ada"} {
		    gdb_test "ptype \$_isvoid" "<<internal function>>"
		} else {
		    gdb_test "ptype \$_isvoid" "<internal function>"
		}

	That will be subject of the following patch.

	gdb: fix dealloc function not being called for frame 0
	Tom de Vries reported [1] a regression in gdb.btrace/record_goto.exp
	caused by 6d3717d4c4 ("gdb: call frame unwinders' dealloc_cache methods

	I managed to narrow it down to:

	    $ ./gdb -nx -q --data-directory=data-directory testsuite/outputs/gdb.btrace/record_goto/record_goto -ex "start" -ex "record btrace" -ex "next"

	... and then doing repeatedly "record goto 19" and "record goto 27".
	Eventually, I get:

	since been wiped by reinit_frame_cache.

	Before the aforementioned, unwinder deallocation functions were called
	by iterating on the frame chain, starting with the sentinel frame, like
	so:

	  /* Tear down all frame caches.  */
	  for (frame_info *fi = sentinel_frame; fi != NULL; fi = fi->prev)
	    {
	      if (fi->prologue_cache && fi->unwind->dealloc_cache)
		fi->unwind->dealloc_cache (fi, fi->prologue_cache);
	      if (fi->base_cache && fi->base->unwind->dealloc_cache)
		fi->base->unwind->dealloc_cache (fi, fi->base_cache);
	    }

	After that patch, we relied on the fact that all frames are (supposedly)
	in the frame_stash.  A deletion function was added to the frame_stash
	hash table, so that dealloc functions would be called when emptying the
	frame stash.  There is one case, however, where a frame_info is not in
	the frame stash.  That is when we create the frame_info for the current
	frame (level 0, unwound from the sentinel frame), but don't compute its
	frame id.  The computation of the frame id for that frame (and only that
	frame, AFAIK) is done lazily.  And putting a frame_info in the frame stash
	requires knowing its id.  So a frame 0 whose frame id is not computed
	yet is necessarily not in the frame stash.

	When replaying with btrace, record_btrace_frame_sniffer insert entries
	corresponding to frames in the "bfcache" hash table.  It then relies on
	record_btrace_frame_dealloc_cache being called for each frame to remove
	all those entries when the frames get invalidated.  If a frame reinit
	happens while frame 0's id is not computed  (and therefore that frame is
	not in frame_stash), record_btrace_frame_dealloc_cache does not get
	called for it, and it leaves a stale entry in bfcache.  That then leads
	to a use-after-free when that entry is accessed later, which ASan
	catches.

	The proposed solution is to explicitly call frame_info_del on frame 0,
	if it exists, and if its frame id is not computed.  If its frame id is
	computed, it is expected that it will be in the frame stash, so it will
	be "deleted" through that.

	Remove RETURNS from BFD chew comments
	When reading the BFD manual, I noticed text like this:

	     -- Function: bool bfd_close (bfd *abfd);
		 Close a BFD. If the BFD was open for writing, then pending
		 operations are completed and the file written out and closed.  If
	    ...
	       *Returns*
	    'TRUE' is returned if all is ok, otherwise 'FALSE'.

	The *Returns*, like the *Synopsis* in the earlier patch, is
	un-info-like.  It's also used inconsistently.

	This patch removes all the uses of the RETURNS word and removes it
	entirely from the chew scripts.  Now this example reads:

	     -- Function: bool bfd_close (bfd *abfd);
		 Close a BFD. If the BFD was open for writing, then pending
		 operations are completed and the file written out and closed.  If
	    ...
		 'TRUE' is returned if all is ok, otherwise 'FALSE'.

	In a few cases I had to slightly reword the comment.  There were also
	a couple of cases where there was redundant text.  In these cases I
	just dropped the RETURNS copy.

	Use @deftypefn in chew output
	When reading the BFD info manual, function definitions looked very
	strange to me:

	    *Synopsis*
		 long bfd_get_mtime (bfd *abfd);
	       *Description*
	    Return the file modification time (as read from the file system, or from
	    the archive header for archive members).

	The *Synopsis* and *Description* text in particular is very un-info-like.

	To fix this, I tried removing the *Synopsis* text and having FUNCTION
	use @deftypefn instead.  However, this ended up requiring some new
	state, because SYNOPSIS can appear without FUNCTION.  This in turn
	required "catstrif" (I considered adding FORTH-style if-else-then, but
	in the end decided on an ad hoc approach).

	After this the result looks like:

	 -- Function: long bfd_get_mtime (bfd *abfd);
	     Return the file modification time (as read from the file system, or
	     from the archive header for archive members).

	This patch also reorders a few documentation comments to ensure that
	SYNOPSIS comes before DESCRIPTION.  This is the more common style and
	is also now required by doc.str.

	gdb: store internalvars in an std::map
	In a test downstream in ROCgdb, we had a test case failing when
	GDB_REVERSE_INIT_FUNCTIONS was set.  The test was assuming a particular
	order in the output of "show convenience".  And the order changes when
	running with GDB_REVERSE_INIT_FUNCTIONS.

	I think that a nice way to fix it is to make the output of "show
	convenience" sorted, and therefore stable.  Ideally, I think that the
	the user-visible behavior of GDB should not change when using
	GDB_REVERSE_INIT_FUNCTIONS.  Plus, it makes the output of "show
	convenience" look nice, not that it's really important.

	Implement this by storing the internal vars in an std::map, which is a
	sorted container.

	Do not record a rejected target description
	When connecting to a certain target, gdb issues a warning about the
	target description:

	    (gdb) target remote localhost:7947
	    Remote debugging using localhost:7947
	    warning: Architecture rejected target-supplied description

	If you then kill the inferior and change the exec-file, this will
	happen:

	    (gdb) file bar
	    Architecture of file not recognized.

	After this, debugging doesn't work very well.

	What happens here is that, despite the warning,
	target_find_description records the downloaded description in the
	target_desc_info.  Then the "file" command ends up calling
	set_gdbarch_from_file, which uses that description.

	It seems to me that, because the architecture rejected the
	description, it should not be used.  That is what this patch
	implements.

	gdb/manual: Move @findex entries
	The manual currently has many cases like these:

	 @item $_gdb_setting_str (@var{setting})
	 @findex $_gdb_setting_str@r{, convenience function}

	As suggested by Eli, move the @findex entries before @item so that the
	index records the position of @item, and the Info reader places you
	there when you use index-search.

	I went over all @findex calls in the manual, and most are like the
	above.  Most either appear before @item, or before @subheading, like:

	 @subheading The @code{-break-after} Command
	 @findex -break-after

	I fixed all of them.

	There are findex entries in annotate.texinfo,python.texi, and
	stabs.texinfo as well, though those all look right to me already.

	Tested by typing "i _isvoid" (@item case) and "i -complete"
	(@subheading case) in an Info reader, and checking where those took
	me.

	Apparently I missed that the older ifort Intel compiler actually emits
	slightly different debug info again:

	                DW_AT_byte_size	(0x20)

	[gdb/testsuite] Add xfail in gdb.python/py-record-btrace.exp
	There's a HW bug affecting Processor Trace on some Intel processors
	(Ice Lake to Raptor Lake microarchitectures).

	The bug was exposed by linux kernel commit 670638477aed
	("perf/x86/intel/pt: Opportunistically use single range output mode"),
	added in version v5.5.0, and was worked around by commit ce0d998be927
	("perf/x86/intel/pt: Fix sampling using single range output") in version
	6.1.0.

	The bug manifests (on a Performance-core of an i7-1250U, an Alder Lake cpu) in
	a single test-case:
	...
	(gdb) python insn = r.instruction_history^M
	warning: Decode error (-20) at instruction 33 (offset = 0x3d6a, \
	  pc = 0x400501): compressed return without call.^M
	(gdb) FAIL: gdb.python/py-record-btrace.exp: prepare record: \
	  python insn = r.instruction_history
	...

	Add a corresponding XFAIL.

	Note that the i7-1250U has both Performance-cores and Efficient-cores, and on
	an Efficient-Core the test-case runs without any problems, so if the testsuite
	run is not pinned to a specific cpu, the test may either PASS or XFAIL.

	gas: improve interaction between read_a_source_file() and s_linefile()
	read_a_source_file() would bump line numbers only when seeing a newline,
	whereas is_end_of_line[] indicates further end-of-line characters, in
	particular the nul character. s_linefile() attempts to compensate for
	the bump, but was too aggressive with this so far: It should only adjust
	when a newline ends the line. To facilitate such a check, the check for
	nothing else on the line needs to move ahead, which luckily is easily
	possible: The relevant two conditions match, and the function can
	simply return from the body of that earlier instance of the conditional.

	The more strict treatment in s_linefile() then requires an adjustment
	to buffer_and_nest()'s invocation of the function: The line terminator
	now needs to be a newline, not nul.

	Rely on value_ref_ptr::operator->
	Simon pointed out some spots were doing val.get()->mumble, where val
	is a value_ref_ptr.  These were introduced by the function-to-method
	script, replacing older code that passed the result of .get() to a
	function.

	Now that value.h is using methods, we can instead rely on operator->.
	This patch replaces all the newly-introduced instances of this.

	gdb/python: deallocate tui window factories at Python shut down
	The previous commit relied on spotting when a Python defined TUI
	window factory was deleted.  I spotted that the window factories are
	not deleted when GDB shuts down its Python environment, they are only
	deleted when one window factory replaces another.  Consider this
	example Python script:

	  class TestWindowFactory:
	      def __init__(self, msg):
	          self.msg = msg
	          print("Entering TestWindowFactory.__init__: %s" % self.msg)

	      def __call__(self, tui_win):
	          print("Entering TestWindowFactory.__call__: %s" % self.msg)
	          return TestWindow(tui_win, self.msg)

	      def __del__(self):
	          print("Entering TestWindowFactory.__del__: %s" % self.msg)

	  gdb.register_window_type("test_window", TestWindowFactory("A"))
	  gdb.register_window_type("test_window", TestWindowFactory("B"))

	And this GDB session:

	  (gdb) source tui.py
	  Entering TestWindowFactory.__init__: A
	  Entering TestWindowFactory.__init__: B
	  Entering TestWindowFactory.__del__: B
	  (gdb) quit

	Notice that when the 'B' window replaces the 'A' window we see the 'A'
	object being deleted.  But, when Python is shut down (after the
	'quit') the 'B' object is never deleted.

	Instead, GDB retains a reference to the window factory object, which
	forces the Python object to remain live even after the Python
	interpreter itself has been shut down.

	The references themselves are held in a dynamically allocated
	std::unordered_map (in tui/tui-layout.c) which is never deallocated,
	thus the underlying Python references are never decremented to zero,
	and so GDB never tries to delete these Python objects.

	This commit is the first half of the work to clean up this edge case.

	All gdbpy_tui_window_maker objects (the objects that implement the
	TUI window factory callback for Python defined TUI windows), are now
	linked together into a global list using the intrusive list mechanism.

	When GDB shuts down the Python interpreter we can now walk this global
	list and release the reference that is held to the underlying Python
	object.  By releasing this reference the Python object will now be
	deleted.

	I've added a new assert in gdbpy_tui_window_maker::operator(), this
	will catch the case where we somehow end up in here after having
	reset the reference to the underlying Python object.  I don't think
	this should ever happen though as we only clear the references when
	shutting down the Python interpreter, and the ::operator() function is
	only called when trying to apply a new TUI layout - something that
	shouldn't happen while GDB itself is shutting down.

	This commit does not update the std::unordered_map in tui-layout.c,
	that will be done in the next commit.

	gdb/python: allow Python TUI windows to be replaced
	The documentation for gdb.register_window_type says:

	  "...  It's an error to try to replace one of the built-in windows,
	  but other window types can be replaced. ..."

	I take this to mean that if I imported a Python script like this:

	  gdb.register_window_type('my_window', FactoryFunction)

	Then GDB would have a new TUI window 'my_window', which could be
	created by calling FactoryFunction().  If I then, in the same GDB
	session imported a script which included:

	  gdb.register_window_type('my_window', UpdatedFactoryFunction)

	Then GDB would replace the old 'my_window' factory with my new one,
	GDB would now call UpdatedFactoryFunction().

	This is pretty useful in practice, as it allows users to iterate on
	their window implementation within a single GDB session.

	However, right now, this is not how GDB operates.  The second call to
	register_window_type is basically ignored and the old window factory
	is retained.

	This is because in tui_register_window (tui/tui-layout.c) we use
	std::unordered_map::emplace to insert the new factory function, and
	emplace doesn't replace an existing element in an unordered_map.

	In this commit, before the emplace call, I now search for an already
	existing element, and delete any matching element from the map, the
	emplace call will then add the new factory function.

	Fix doc build dependencies for --with-system-readline
	PR build/30108 concerns building gdb documentation with
	--with-sytem-readline.  If the in-tree readline directory is
	missing, though, the docs will fail to build:

	make[4]: Entering directory '/home/keiths/work/readline-doc-issue/linux/gdb/doc'
	make[4]: *** No rule to make target '../../../src/gdb/doc/../../readline/readline/doc/rluser.texi', needed by 'gdb.info'.  Stop.

	The listed file (and hsuser.texi) are conditionally included by gdb.texinfo.
	When system readline is used, gdb/configure.ac will leave
	READLINE_TEXI_INCFLAGS empty, causing doc/Makefile.in to output a line to
	$BUILD/doc/GDBvn.texi with "@set SYSTEM_READLINE".  This surpresses the
	inclusion of the missing files. They are not needed or used in this
	scenario.

	However, GDB_DOC_SOURCE_INCLUDES always lists these two files as dependencies,
	thus provoking the build error whenever readline/ is missing.

	This patch fixes this by creating (essentially) a conditional setting of the
	dependencies to be included from readline.

	unknown 32-bit microMIPS instructions were disassembled as a raw

	gdb/testsuite: look for hipcc in env(ROCM_PATH)
	If the hipcc compiler cannot be found in dejagnu's tool_root_dir, look
	for it in $::env(ROCM_PATH) (if set).  If hipcc is still not found,
	fallback to "hipcc" so the compiler will be searched in the PATH.  This
	removes the fallback to the hard-coded "/opt/rocm/bin" prefix.

	This change is done so ROCM tools are searched in a uniform manner.

	gdb/testsuite: allow_hipcc_tests tests the hipcc compiler
	Update allow_hipcc_tests so all gdb.rocm tests are skipped if we do not
	have a working hipcc compiler available.

	To achieve this, adjust gdb_simple_compile to ensure that the hip
	program is saved in a ".cpp" file before calling hipcc otherwise
	compilation will fail.

	One thing to note is that it is possible to have a hipcc installed with
	a CUDA backend.  Compiling with this back-end will successfully result
	in an application, but GDB cannot debug it (at least for the offload
	part). In the context of the gdb.rocm tests, we want to detect such
	situation where gdb_simple_compile would give a false positive.

	To achieve this, this patch checks that there is at least one AMDGPU
	device available and that hipcc can compile for this or those targets.
	Detecting the device is done using the rocm_agent_enumerator tool which
	is installed with the all ROCm installations (it is used by hipcc to
	detect identify targets if this is not specified on the comand line).

	This patch also makes the allow_hipcc_tests proc a cached proc.

	gdb/c++: fix handling of breakpoints on @plt symbols
	This commit should fix PR gdb/20091, PR gdb/17201, and PR gdb/17071.
	Additionally, PR gdb/17199 relates to this area of code, but is more
	of a request to refactor some parts of GDB, this commit does not
	address that request, but it is probably worth reading that PR when
	looking at this commit.

	When the current language is C++, and the user places a breakpoint on
	a function in a shared library, GDB will currently find two locations
	for the breakpoint, one location will be within the function itself as
	we would expect, but the other location will be within the PLT table
	for the call to the named function.  Consider this session:

	  $ gdb -q /tmp/breakpoint-shlib-func
	  Reading symbols from /tmp/breakpoint-shlib-func...
	  (gdb) start
	  Temporary breakpoint 1 at 0x40112e: file /tmp/breakpoint-shlib-func.cc, line 20.
	  Starting program: /tmp/breakpoint-shlib-func

	  Temporary breakpoint 1, main () at /tmp/breakpoint-shlib-func.cc:20
	  20	  int answer = foo ();
	  (gdb) break foo
	  Breakpoint 2 at 0x401030 (2 locations)
	  (gdb) info breakpoints
	  Num     Type           Disp Enb Address            What
	  2       breakpoint     keep y   <MULTIPLE>
	  2.1                         y   0x0000000000401030 <foo()@plt>
	  2.2                         y   0x00007ffff7fc50fd in foo() at /tmp/breakpoint-shlib-func-lib.cc:20

	This is not the expected behaviour.  If we compile the same test using
	a C compiler then we see this:

	  (gdb) break foo
	  Breakpoint 2 at 0x7ffff7fc50fd: file /tmp/breakpoint-shlib-func-c-lib.c, line 20.
	  (gdb) info breakpoints
	  Num     Type           Disp Enb Address            What
	  2       breakpoint     keep y   0x00007ffff7fc50fd in foo at /tmp/breakpoint-shlib-func-c-lib.c:20

	Here's what's happening.  When GDB parses the symbols in the main
	executable and the shared library we see a number of different symbols
	for foo, and use these to create entries in GDB's msymbol table:

	  - In the main executable we see a symbol 'foo@plt' that points at
	    the plt entry for foo, from this we add two entries into GDB's
	    msymbol table, one called 'foo@plt' which points at the plt entry
	    and has type mst_text, then we create a second symbol, this time
	    called 'foo' with type mst_solib_trampoline which also points at
	    the plt entry,

	  - Then, when the shared library is loaded we see another symbol
	    called 'foo', this one points at the actual implementation in the
	    shared library.  This time GDB creates a msymbol called 'foo' with
	    type mst_text that points at the implementation.

	This means that GDB creates 3 msymbols to represent the 2 symbols
	found in the executable and shared library.

	When the user creates a breakpoint on 'foo' GDB eventually ends up in
	search_minsyms_for_name (linespec.c), this function then calls
	iterate_over_minimal_symbols passing in the name we are looking for
	wrapped in a lookup_name_info object.

	In iterate_over_minimal_symbols we iterate over two hash tables (using
	the name we're looking for as the hash key), first we walk the hash
	table of symbol linkage names, then we walk the hash table of
	demangled symbol names.

	When the language is C++ the symbols for 'foo' will all have been
	mangled, as a result, in this case, the iteration of the linkage name
	hash table will find no matching results.

	However, when we walk the demangled hash table we do find some
	results.  In order to match symbol names, GDB obtains a symbol name
	matching function by calling the get_symbol_name_matcher method on the
	language_defn class.  For C++, in this case, the matching function we
	use is cp_fq_symbol_name_matches, which delegates the work to
	strncmp_iw_with_mode with mode strncmp_iw_mode::MATCH_PARAMS and
	language set to language_cplus.

	The strncmp_iw_mode::MATCH_PARAMS mode means that strncmp_iw_mode will
	skip any parameters in the demangled symbol name when checking for a
	match, e.g. 'foo' will match the demangled name 'foo()'.  The way this
	is done is that the strings are matched character by character, but,
	once the string we are looking for ('foo' here) is exhausted, if we
	are looking at '(' then we consider the match a success.

	Lets consider the 3 symbols GDB created.  If the function declaration
	is 'void foo ()' then from the main executable we added symbols
	'_Z3foov@plt' and '_Z3foov', while from the shared library we added
	another symbol call '_Z3foov'.  When these are demangled they become
	'foo()@plt', 'foo()', and 'foo()' respectively.

	Now, the '_Z3foov' symbol from the main executable has the type
	mst_solib_trampoline, and in search_minsyms_for_name, we search for
	any symbols of type mst_solib_trampoline and filter these out of the
	results.

	However, the '_Z3foov@plt' symbol (from the main executable), and the
	'_Z3foov' symbol (from the shared library) both have type mst_text.

	During the demangled name matching, due to the use of MATCH_PARAMS
	mode, we stop the comparison as soon as we hit a '(' in the demangled
	name.  And so, '_Z3foov@plt', which demangles to 'foo()@plt' matches
	'foo', and '_Z3foov', which demangles to 'foo()' also matches 'foo'.

	By contrast, for C, there are no demangled hash table entries to be
	iterated over (in iterate_over_minimal_symbols), we only consider the
	linkage name symbols which are 'foo@plt' and 'foo'.  The plain 'foo'
	symbol obviously matches when we are looking for 'foo', but in this
	case the 'foo@plt' will not match due to the '@plt' suffix.

	And so, when the user asks for a breakpoint in 'foo', and the language
	is C, search_minsyms_for_name, returns a single msymbol, the mst_text
	symbol for foo in the shared library, while, when the language is C++,
	we get two results, '_Z3foov' for the shared library function, and
	'_Z3foov@plt' for the plt entry in the main executable.

	I propose to fix this in strncmp_iw_with_mode.  When the mode is
	MATCH_PARAMS, instead of stopping at a '(' and assuming the match is a
	success, GDB will instead search forward for the matching, closing,
	')', effectively skipping the parameter list, and then resume
	matching.  Thus, when comparing 'foo' to 'foo()@plt' GDB will
	effectively compare against 'foo@plt' (skipping the parameter list),
	and the match will fail, just as it does when the language is C.

	There is one slight complication, which is revealed by the test
	gdb.linespec/cpcompletion.exp, when searching for the symbol of a
	const member function, the demangled symbol will have 'const' at the
	end of its name, e.g.:

	  struct_with_const_overload::const_overload_fn() const

	Previously, the matching would stop at the '(' character, but after my
	change the whole '()' is skipped, and the match resumes.  As a result,
	the 'const' modifier results in a failure to match, when previously
	GDB would have found a match.

	To work around this issue, in strncmp_iw_with_mode, when mode is
	MATCH_PARAMS, after skipping the parameter list, if the next character
	is '@' then we assume we are looking at something like '@plt' and
	return a value indicating the match failed, otherwise, we return a
	value indicating the match succeeded, this allows things like 'const'
	to be skipped.

	With these changes in place I now see GDB correctly setting a
	breakpoint only at the implementation of 'foo' in the shared library.

	gdb: use -1 for breakpoint::task default value
	Within the breakpoint struct we have two fields ::thread and ::task
	which are used for thread or task specific breakpoints.  When a
	breakpoint doesn't have a specific thread or task then these fields
	have the values -1 and 0 respectively.

	There's no particular reason (as far as I can tell) why these two
	"default" values are different, and I find the difference a little
	confusing.  Long term I'd like to potentially fold these two fields
	into a single field, but that isn't what this commit does.

	What this commit does is switch to using -1 as the "default" value for
	both fields, this means that the default for breakpoint::task has
	changed from 0 to -1.   I've updated all the code I can find that
	relied on the value of 0, and I see no test regressions, especially in
	gdb.ada/tasks.exp, which still fully passes.

	There should be no user visible changes after this commit.

	gdb: only allow one of thread or task on breakpoints or watchpoints
	After this mailing list posting:

	  https://sourceware.org/pipermail/gdb-patches/2023-February/196607.html

	it seems to me that in practice an Ada task maps 1:1 with a GDB
	thread, and so it doesn't really make sense to allow uses to give both
	a thread and a task within a single breakpoint or watchpoint
	condition.

	This commit updates GDB so that the user will get an error if both
	are specified.

	I've added new tests to cover the CLI as well as the Python and Guile
	APIs.  For the Python and Guile testing, as far as I can tell, this
	was the first testing for this corner of the APIs, so I ended up
	adding more than just a single test.

	For documentation I've added a NEWS entry, but I've not added anything
	to the docs themselves.  Currently we document the commands with a
	thread-id or task-id as distinct command, e.g.:

	  'break LOCSPEC task TASKNO'
	  'break LOCSPEC task TASKNO if ...'
	  'break LOCSPEC thread THREAD-ID'
	  'break LOCSPEC thread THREAD-ID if ...'

	As such, I don't believe there is any indication that combining 'task'
	and 'thread' would be expected to work; it seems clear to me in the
	above that those four options are all distinct commands.

	I think the NEWS entry is enough that if someone is combining these
	keywords (it's not clear what the expected behaviour would be in this
	case) then they can figure out that this was a deliberate change in
	GDB, but for a new user, the manual doesn't suggest combining them is
	OK, and any future attempt to combine them will give an error.

	The 'thread 2' in here is using the global thread-id, we should

	gdb: add test for readline handling very long commands
	The test added in this commit tests for a long fixed readline issue

	Which was merged into readline 6.0 (released ~2010).  The issue was

	  ---------------------

	I recreated the above crash by a little light hacking on GDB, and then
	linking GDB against readline 5.2.  The above stack trace was generated
	from the test included in this patch, and matches the trace that was
	included in the original bug report.

	It is worth acknowledging that without hacking things GDB has a
	minimum requirement of readline 7.0.  This test is not about checking
	whether GDB has been built against an older version of readline, it is
	about checking that readline doesn't regress in this area.

	gdb: remove unnecessary 'dir' commands from gdb-gdb.gdb script
	While debugging GDB I used 'show directories' and spotted lots of
	entries that didn't make much sense. Here are all the entries that are
	in my directories list:

	  /tmp/binutils-gdb/build
	  /tmp/binutils-gdb/build/../../src/gdb
	  /tmp/binutils-gdb/build/../../src/gdb/../bfd
	  /tmp/binutils-gdb/build/../../src/gdb/../libiberty
	  $cdir
	  $cwd

	Notice the second, third, and fourth entries in this list, these
	should really be:

	  /tmp/binutils-gdb/build/../src/gdb
	  /tmp/binutils-gdb/build/../src/gdb/../bfd
	  /tmp/binutils-gdb/build/../src/gdb/../libiberty

	The problem is because I generally run everything from the top level
	build directory, not the gdb/ sub-directory, thus, I start GDB like:

	  ./gdb/gdb --data-directory ./gdb/data-directory

	If run GDB under GDB, then I end up loading the gdb/gdb-gdb.gdb
	script, which contains these lines:

	  dir ../../src/gdb/../libiberty
	  dir ../../src/gdb/../bfd
	  dir ../../src/gdb
	  dir .

	These commands only make sense when running within the gdb/
	sub-directory.

	However, my debugging experience doesn't seem to be degraded at all, I
	can still see the GDB source code just fine; which is because the
	directory list still contains $cdir.

	The build/gdb/gdb-gdb.gdb script is created from the
	src/gdb/gdb-gdb.gdb.in template, which includes the automake @srcdir@
	markers.

	The 'dir' commands have mostly been around since the sourceware
	repository was first created, though this commit 67f0714670383a did
	reorder some of the 'dir' commands, which would seem to indicate these
	commands were important to some people, at some time.

	One possible fix would be to replace @srcdir@ with @abs_srcdir@, this
	would ensure that the entries added were all valid, no matter the
	user's current directory when debugging GDB.

	However... I'd like to propose that we instead remove all the extra
	directories completely.  My hope is that, with more recent tools, the
	debug information should allow us to correctly find all of the source
	files without having to add any extra 'dir' entries.  Obviously,
	commit 67f0714670383a does make me a little nervous, but the
	gdb-gdb.gdb script isn't something a non-maintainer will be using, so
	I think we can afford to be a little more aggressive here.  If it
	turns out the 'dir' entries are needed then we can add them back, but
	actually document why they are needed.  Plus, when we add them back we
	will use @abs_srcdir@ instead of @srcdir@.

	...

	ISTM me there's no reason for the i386 unwinders to be there for amd64.

	Furthermore, there's a generic need to play around with enabling and disabling
	unwinders, see PR8434.  Currently, that's only available for both the dwarf2
	unwinders at once using "maint set dwarf unwinders on/off".

	If I manually disable the "amd64 epilogue" unwinder, the "i386 epilogue"
	unwinder becomes active and gives the wrong answer, while I'm actually
	interested in the result of the dwarf2 unwinder.  Of course I can also
	manually disable the "i386 epilogue", but I take the fact that I have to do
	that as evidence that on amd64, the "i386 epilogue" is not only unnecessary,
	but in the way.

	Fix this by only adding the i386 unwinders if
	"info.bfd_arch_info->bits_per_word == 32".

	Note that the x32 abi (x86_64/-mx32):
	- has the same unwinder list as amd64 (x86_64/-m64) before this commit,
	- has info.bfd_arch_info->bits_per_word == 64, the same as amd64, and
	  consequently,
	- has the same unwinder list as amd64 after this commit.

	Tested on x86_64-linux, -m64 and -m32.  Not tested with -mx32.

	objdump -D of bss sections and -s with -j
	There is some inconsistency between the behaviour of objdump -D and
	objdump -s, both supposedly operating on all sections by default.
	objdump -s ignores bss sections, while objdump -D dissassembles the
	zeros.  Fix this by making objdump -D ignore bss sections too.

	Furthermore, "objdump -s -j .bss" doesn't dump .bss as it should,
	since the user is specifically asking to look at all those zeros.

	This change does find some tests that used objdump -D with expected
	output in bss-style sections.  I've updated all the msp430 tests that
	just wanted to find a non-empty section to look at section headers
	instead, making the tests slightly more stringent.  The ppc xcoff and
	spu tests are fixed by adding -j options to objdump, which makes the
	tests somewhat more lenient.

	gdb/source: Fix open_source_file error handling
	open_source_file relies on errno to communicate the reason for a missing
	source file.

	open_source_file may also call debuginfod_find_source.  It is possible
	for debuginfod_find_source to set errno to a value unrelated to the
	reason for a failed download.

	This can result in bogus error messages being reported as the reason for
	a missing source file.  The following error message should instead be
	"No such file or directory":

	  Temporary breakpoint 1, 0x00005555556f4de0 in main ()
	  (gdb) list
	  Downloading source file /usr/src/debug/glibc-2.36-8.fc37.x86_64/elf/<built-in>
	  1       /usr/src/debug/glibc-2.36-8.fc37.x86_64/elf/<built-in>: Directory not empty.

	Fix this by having open_source_file return a negative errno if it fails
	to open a source file.  Use this value to generate the error message
	instead of errno.

	GDB: Introduce limited array lengths while printing values
	This commit introduces the idea of loading only part of an array in
	order to print it, what I call "limited length" arrays.

	The motivation behind this work is to make it possible to print slices
	of very large arrays, where very large means bigger than
	`max-value-size'.

	Consider this GDB session with the current GDB:

	  (gdb) set max-value-size 100
	  (gdb) p large_1d_array
	  value requires 400 bytes, which is more than max-value-size
	  (gdb) p -elements 10 -- large_1d_array
	  value requires 400 bytes, which is more than max-value-size

	notice that the request to print 10 elements still fails, even though 10
	elements should be less than the max-value-size.  With a patched version
	of GDB:

	  (gdb) p -elements 10 -- large_1d_array
	  $1 = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9...}

	So now the print has succeeded.  It also has loaded `max-value-size'
	worth of data into value history, so the recorded value can be accessed
	consistently:

	  (gdb) p -elements 10 -- $1
	  $2 = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9...}
	  (gdb) p $1
	  $3 = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,
	    20, 21, 22, 23, 24, <unavailable> <repeats 75 times>}
	  (gdb)

	Accesses with other languages work similarly, although for Ada only
	C-style [] array element/dimension accesses use history.  For both Ada
	and Fortran () array element/dimension accesses go straight to the
	inferior, bypassing the value history just as with C pointers.

	GDB/testsuite: Add `-nonl' option to `gdb_test'

	GDB: Only make data actually retrieved into value history available
	While it makes sense to allow accessing out-of-bounds elements in the
	debuggee and see whatever there might happen to be there in memory (we
	are a debugger and not a programming rules enforcement facility and we
	want to make people's life easier in chasing bugs), e.g.:

	  (gdb) print one_hundred[-1]
	  $1 = 0
	  (gdb) print one_hundred[100]
	  $2 = 0
	  (gdb)

	we shouldn't really pretend that we have any meaningful data around
	values recorded in history (what these commands really retrieve are
	current debuggee memory contents outside the original data accessed,
	really confusing in my opinion).  Mark values recorded in history as
	such then and verify accesses to be in-range for them:

	  (gdb) print one_hundred[-1]
	  $1 = <unavailable>
	  (gdb) print one_hundred[100]
	  $2 = <unavailable>

	Add a suitable test case, which also covers integer overflows in data
	location calculation.

	GDB: Fix the mess with value byte/bit range types
	Consistently use the LONGEST and ULONGEST types for value byte/bit
	offsets and lengths respectively, avoiding silent truncation for ranges
	exceeding the 32-bit span, which may cause incorrect matching.  Also
	report a conversion overflow on byte ranges that cannot be expressed in
	terms of bits with these data types, e.g.:

	  (gdb) print one_hundred[1LL << 58]
	  Integer overflow in data location calculation
	  (gdb) print one_hundred[(-1LL << 58) - 1]
	  Integer overflow in data location calculation
	  (gdb)

	Previously such accesses would be let through with unpredictable results
	produced.

	GDB: Ignore `max-value-size' setting with value history accesses
	We have an inconsistency in value history accesses where array element
	accesses cause an error for entries exceeding the currently selected
	`max-value-size' setting even where such accesses successfully complete
	for elements located in the inferior, e.g.:

	  (gdb) p/d one
	  $1 = 0
	  (gdb) p/d one_hundred
	  $2 = {0 <repeats 100 times>}
	  (gdb) p/d one_hundred[99]
	  $3 = 0
	  (gdb) set max-value-size 25
	  (gdb) p/d one_hundred
	  value requires 100 bytes, which is more than max-value-size
	  (gdb) p/d one_hundred[99]
	  $7 = 0
	  (gdb) p/d $2
	  value requires 100 bytes, which is more than max-value-size
	  (gdb) p/d $2[99]
	  value requires 100 bytes, which is more than max-value-size
	  (gdb)

	According to our documentation the `max-value-size' setting is a safety
	guard against allocating an overly large amount of memory.  Moreover a
	statement in documentation says, concerning this setting, that: "Setting
	this variable does not affect values that have already been allocated
	within GDB, only future allocations."  While in the implementer-speak
	the sentence may be unambiguous I think the outside user may well infer
	that the setting does not apply to values previously printed.

	Therefore rather than just fixing this inconsistency it seems reasonable
	to lift the setting for value history accesses, under an implication
	that by having been retrieved from the debuggee they have already passed
	the safety check.  Do it then, by suppressing the value size check in
	`value_copy' -- under an observation that if the original value has been
	already loaded (i.e. it's not lazy), then it must have previously passed
	said check -- making the last two commands succeed:

	  (gdb) p/d $2
	  $8 = {0 <repeats 100 times>}
	  (gdb) p/d $2 [99]
	  $9 = 0
	  (gdb)

	Expand the testsuite accordingly, covering both value history handling
	and the use of `value_copy' by `make_cv_value', used by Python code.

	gdb/testsuite: fix gdb.gdb/selftest.exp for native-extended-gdbserver
	Following commit 4e2a80ba606 ("gdb/testsuite: expect SIGSEGV from top
	GDB spawn id"), the next failure I get in gdb.gdb/selftest.exp, using
	the native-extended-gdbserver, is:

	    (gdb) PASS: gdb.gdb/selftest.exp: send ^C to child process
	    signal SIGINT
	    Continuing with signal SIGINT.
	    FAIL: gdb.gdb/selftest.exp: send SIGINT signal to child process (timeout)

	The problem is that in this gdb_test_multiple:

	    set description "send SIGINT signal to child process"
	    gdb_test_multiple "signal SIGINT" "$description" {
		-re "^signal SIGINT\r\nContinuing with signal SIGINT.\r\nQuit\r\n.* $" {
		    pass "$description"
		}
	    }

	The "Continuing with signal SIGINT" portion is printed by the top GDB,
	while the Quit portion is printed by the bottom GDB.  As the
	gdb_test_multiple is written, it expects both the the top GDB's spawn
	id.

	Fix this by splitting the gdb_test_multiple in two.  The first one
	expects the "Continuing with signal SIGINT" from the top GDB.  The
	second one expect "Quit"  and the "(xgdb)" prompt from
	$inferior_spawn_id.  When debugging natively, this spawn id will be the
	same as the top GDB's spawn id, but it's different when debugging with
	GDBserver.

	The test-case intends to set the breakpoint on line number 63 in

	It tries to do so by specifying "break 63", which specifies a line in the
	"current source file".

	Due to the KFAIL PR, gdb stopped in __libc_siglongjmp, and because of presence
	of debug info, the "current source file" becomes glibc's ./setjmp/longjmp.c.

	Consequently, setting the breakpoint fails.

	Fix this by adding a $subdir/$srcfile: prefix to the breakpoint linespecs.

	I've managed to reproduce the FAIL on x86_64/-m32, by installing the

	generic bfd code when the bfd is closed.  bfd_check_format also
	releases memory when object_p fails, so while it wouldn't be wrong
	to bfd_release at bad_format_free in mmo_object_p, it's a little extra
	code and work for no gain.

		* mmo.c (mmo_object_p): bfd_alloc rather than bfd_malloc
		lop_stab_symbol.  Don't free/release on error.
		(mmo_get_spec_section): bfd_zalloc rather than bfd_zmalloc
		section buffer.
		(mmo_scan): Free fname on another error path.

	x86: drop use of VEX3SOURCES
	The attribute really specifies that the sum of register and memory
	operands is 4. Express it like that in most places, while using the 2nd
	(apart from XOP) CPU feature flags (FMA4) in reversed operand matching
	logic.

	With the use in build_modrm_byte() gone, part of an assertion there
	also becomes meaningless - simplify that at the same time.

	With all uses of the opcode modifier field gone, also drop that.

	x86: drop use of XOP2SOURCES

	With that added, the only further missing piece to use more generic code

	code.

	x86: limit use of XOP2SOURCES
	The VPROT* forms with an immediate operand are entirely standard in the
	way their ModR/M bytes are built. There's no reason to invoke special
	case code. With that the handling of an immediate there can also be
	dropped; it was partially bogus anyway, as in its "no memory operands"
	portion it ignores the possibility of an immediate operand (which was
	okay only because that case was already handled by more generic code).

	x86: move (and rename) opcodespace attribute
	This really isn't a "modifier" and rather ought to live next to the base
	opcode anyway. Use the bits we presently have available to fit in the
	field, renaming it to opcode_space. As an intended side effect this
	helps readability at the use sites, by shortening the references quite a
	bit.

	In generated code arrange for human readable output, by using the
	SPACE_* constants there rather than raw numbers. This may aid debugging
	down the road.

	Now that we have identifiers for the mnemonic strings we can avoid

	Note that the MOV optimization can be engaged by the earlier LEA one,

	Add full display feature to dwarf-mode.el
	I've found that I often use dwarf-mode with relatively small test
	files.  In this situation, it's handy to be able to expand all the
	DWARF, rather than moving to each "..." separately and using C-u C-m.

	This patch implements this feature.  It also makes a couple of other
	minor changes:

	* I removed a stale FIXME from dwarf-mode.  In practice I find I often
	  use "g" to restore the buffer to a pristine state; checking the file
	  mtime would work against this.

	* I tightened the regexp in dwarf-insert-substructure.  This prevents
	  the C-m binding from trying to re-read a DIE which has already been
	  expanded.

	* Finally, I've bumped the dwarf-mode version number so that this
	  version can easily be installed using package.el.

	Increase size of main_type::nfields
	main_type::nfields is a 'short', and has been for many years.  PR
	c++/29985 points out that 'short' is too narrow for an enum that
	contains more than 2^15 constants.

	This patch bumps the size of 'nfields'.  To verify that the field
	isn't directly used, it is also renamed.  Note that this does not
	affect the size of main_type on x86-64 Fedora 36.  And, if it does
	have a negative effect somewhere, it's worth considering that types
	could be shrunk more drastically by using subclasses for the different
	codes.

	This is v2 of this patch, which has these changes:

	* I changed nfields to 'unsigned', per Simon's request.  I looked at
	  changing all the uses, but this quickly fans out into a very large
	  patch.  (One additional tweak was needed, though.)

	* I wrote a test case.  I discovered that GCC cannot compile a large
	  enough C test case, so I resorted to using the DWARF assembler.
	  This test doesn't reproduce the crash, but it does fail without the
	  patch.

	Let user C-c when waiting for DWARF index finalization
	In PR gdb/29854, Simon pointed out that it would be good to be able to

	idea here is to be able to interrupt a command like "break" -- not to
	stop the finalization process itself, which runs in a worker thread.

	This patch implements this idea, by changing the index wait functions
	to, by default, allow a quit.  Polling is done, because there doesn't
	seem to be a better way to interrupt a wait on a std::future.

	Clear cached file size when bfd changed to BFD_IN_MEMORY
	If file size is calculated by bfd_get_file_size, as it is by
	_bfd_alloc_and_read calls in coff_object_p, then it is cached and when
	pe_ILF_build_a_bfd converts an archive entry over to BFD_IN_MEMORY,

	because caching is ignored by bfd_get_size when bfd_write_p.)

	I also think the PR 24707 fix is no longer neeeded.  All of the

	checks when reading the symbols from file.  So I'm reverting that fix,

	gdb: give sentinel for user frames distinct IDs, register sentinel frames to the frame cache
	The test gdb.base/frame-view.exp fails like this on AArch64:

	    frame^M
	    #0  baz (z1=hahaha, /home/simark/src/binutils-gdb/gdb/value.c:4056: internal-error: value_fetch_lazy_register: Assertion `next_frame != NULL' failed.^M
	    A problem internal to GDB has been detected,^M
	    further debugging may prove unreliable.^M
	    FAIL: gdb.base/frame-view.exp: with_pretty_printer=true: frame (GDB internal error)

	The sequence of events leading to this is the following:

	 - When we create the user frame (the "select-frame view" command), we
	   create a sentinel frame just for our user-created frame, in
	   create_new_frame.  This sentinel frame has the same id as the regular
	   sentinel frame.

	 - When printing the frame, after doing the "select-frame view" command,
	   the argument's pretty printer is invoked, which does an inferior
	   function call (this is the point of the test).  This clears the frame
	   cache, including the "real" sentinel frame, which sets the
	   sentinel_frame global to nullptr.

	 - Later in the frame-printing process (when printing the second
	   argument), the auto-reinflation mechanism re-creates the user frame
	   by calling create_new_frame again, creating its own special sentinel
	   frame again.  However, note that the "real" sentinel frame, the
	   sentinel_frame global, is still nullptr.  If the selected frame had
	   been a regular frame, we would have called get_current_frame at some
	   point during the reinflation, which would have re-created the "real"
	   sentinel frame.  But it's not the case when reinflating a user frame.

	 - Deep down the stack, something wants to fill in the unwind stop
	   reason for frame 0, which requires trying to unwind frame 1.  This
	   leads us to trying to unwind the PC of frame 1:

	 - AArch64 defines a special "prev register" function,
	   aarch64_dwarf2_prev_register, to handle unwinding the PC.  This
	   function does

	     frame_unwind_register_unsigned (this_frame, AARCH64_LR_REGNUM);

	 - frame_unwind_register_unsigned ultimately creates a lazy register
	   value, saving the frame id of this_frame->next.  this_frame is the
	   user-created frame, to this_frame->next is the special sentinel frame
	   we created for it.  So the saved ID is the sentinel frame ID.

	 - When time comes to un-lazify the value, value_fetch_lazy_register
	   calls frame_find_by_id, to find the frame with the ID we saved.

	 - frame_find_by_id sees it's the sentinel frame ID, so returns the
	   sentinel_frame global, which is, if you remember, nullptr.

	 - We hit the `gdb_assert (next_frame != NULL)` assertion in
	   value_fetch_lazy_register.

	The issues I see here are:

	 - The ID of the sentinel frame created for the user-created frame is
	   not distinguishable from the ID of the regular sentinel frame.  So
	   there's no way frame_find_by_id could find the right frame, in
	   value_fetch_lazy_register.
	 - Even if they had distinguishable IDs, sentinel frames created for
	   user frames are not registered anywhere, so there's no easy way
	   frame_find_by_id could find it.

	This patch addresses these two issues:

	 - Give sentinel frames created for user frames their own distinct IDs
	 - Register sentinel frames in the frame cache, so they can be found
	   with frame_find_by_id.

	I initially had this split in two patches, but I then found that it was
	easier to explain as a single patch.

	Rergarding the first part of the change: with this patch, the sentinel
	frames created for user frames (in create_new_frame) still have
	stack_status == FID_STACK_SENTINEL, but their code_addr and stack_addr
	fields are now filled with the addresses used to create the user frame.
	This ensures this sentinel frame ID is different from the "target"
	sentinel frame ID, as well as any other "user" sentinel frame ID.  If
	the user tries to create the same frame, with the same addresses,
	multiple times, create_sentinel_frame just reuses the existing frame.
	So we won't end up with multiple user sentinels with the same ID.

	Regular "target" sentinel frames remain with code_addr and stack_addr
	unset.

	The concrete changes for that part are:

	 - Remove the sentinel_frame_id constant, since there isn't one
	   "sentinel frame ID" now.  Add the frame_id_build_sentinel function
	   for building sentinel frame IDs and a is_sentinel_frame_id function
	   to check if a frame id represents a sentinel frame.
	 - Replace the sentinel_frame_id check in frame_find_by_id with a
	   comparison to `frame_id_build_sentinel (0, 0)`.  The sentinel_frame
	   global is meant to contain a reference to the "target" sentinel, so
	   the one with addresses (0, 0).
	 - Add stack and code address parameters to create_sentinel_frame, to be
	   able to create the various types of sentinel frames.
	 - Adjust get_current_frame to create the regular "target" sentinel.
	 - Adjust create_new_frame to create a sentinel with the ID specific to
	   the created user frame.
	 - Adjust sentinel_frame_prev_register to get the sentinel frame ID from
	   the frame_info object, since there isn't a single "sentinel frame ID"
	   now.
	 - Change get_next_frame_sentinel_okay to check for a
	   sentinel-frame-id-like frame ID, rather than for sentinel_frame
	   specifically, since this function could be called with another
	   sentinel frame (and we would want the assert to catch it).

	The rest of the change is about registering the sentinel frame in the
	frame cache:

	 - Change frame_stash_add's assertion to allow sentinel frame levels
	   (-1).
	 - Make create_sentinel_frame add the frame to the frame cache.
	 - Change the "sentinel_frame != NULL" check in reinit_frame_cache for a
	   check that the frame stash is not empty.  The idea is that if we only
	   have some user-created frames in the cache when reinit_frame_cache is
	   called, we probably want to emit the frames invalid annotation.  The
	   goal of that check is to avoid unnecessary repeated annotations, I
	   suppose, so the "frame cache not empty" check should achieve that.

	After this change, I think we could theoritically get rid of the
	sentienl_frame global.  That sentinel frame could always be found by
	looking up `frame_id_build_sentinel (0, 0)` in the frame cache.
	However, I left the global there to avoid slowing the typical case down
	for nothing.  I however, noted in its comment that it is an
	optimization.

	With this fix applied, the gdb.base/frame-view.exp now passes for me on
	AArch64.  value_of_register_lazy now saves the special sentinel frame ID
	in the value, and value_fetch_lazy_register is able to find that
	sentinel frame after the frame cache reinit and after the user-created
	frame was reinflated.

	gdb: call frame unwinders' dealloc_cache methods through destroying the frame cache
	Currently, some frame resources are deallocated by iterating on the
	frame chain (starting from the sentinel), calling dealloc_cache.  The
	problem is that user-created frames are not part of that chain, so we
	never call dealloc_cache for them.

	I propose to make it so the dealloc_cache callbacks are called when the
	frames are removed from the frame_stash hash table, by registering a
	deletion function to the hash table.  This happens when
	frame_stash_invalidate is called by reinit_frame_cache.  This way, all
	frames registered in the cache will get their unwinder's dealloc_cache
	callbacks called.

	Note that at the moment, the sentinel frames are not registered in the
	cache, so we won't call dealloc_cache for them.  However, it's just a
	theoritical problem, because the sentinel frame unwinder does not
	provide this callback.  Also, a subsequent patch will change things so
	that sentinel frames are registered to the cache.

	I moved the obstack_free / obstack_init pair below the
	frame_stash_invalidate call in reinit_frame_cache, because I assumed
	that some dealloc_cache would need to access some data on that obstack,
	so it would be better to free it after clearing the hash table.

	Remove block.h includes from some tdep files
	A few tdep files include block.h but do not need to.  This patch
	removes the inclusions.  I checked that this worked correctly by
	examining the resulting .Po file to make sure that block.h was not
	being included by some other route.

	Don't include block.h from expop.h
	expop.h needs block.h for a single inline function.  However, I don't
	think most of the check_objfile functions need to be defined in the
	header (just the templates).  This patch moves the one offending
	function and removes the include.

	Simplify interp::exec / interp_exec - let exceptions propagate
	This patch implements a simplication that I suggested here:

	  https://sourceware.org/pipermail/gdb-patches/2022-March/186320.html

	Currently, the interp::exec virtual method interface is such that
	subclass implementations must catch exceptions and then return them
	via normal function return.

	However, higher up the in chain, for the CLI we get to
	interpreter_exec_cmd, which does:

	  for (i = 1; i < nrules; i++)
	    {
	      struct gdb_exception e = interp_exec (interp_to_use, prules[i]);

	      if (e.reason < 0)
		{
		  interp_set (old_interp, 0);
		  error (_("error in command: \"%s\"."), prules[i]);
		}
	    }

	and for MI we get to mi_cmd_interpreter_exec, which has:

	  void
	  mi_cmd_interpreter_exec (const char *command, char **argv, int argc)
	  {
	  ...
	    for (i = 1; i < argc; i++)
	      {
		struct gdb_exception e = interp_exec (interp_to_use, argv[i]);

		if (e.reason < 0)
		  error ("%s", e.what ());
	      }
	  }

	Note that if those errors are reached, we lose the original
	exception's error code.  I can't see why we'd want that.

	And, I can't see why we need to have interp_exec catch the exception
	and return it via the normal return path.  That's normally needed when
	we need to handle propagating exceptions across C code, like across
	readline or ncurses, but that's not the case here.

	It seems to me that we can simplify things by removing some
	try/catch-ing and just letting exceptions propagate normally.

	Note, the "error in command" error shown above, which only exists in
	the CLI interpreter-exec command, is only ever printed AFAICS if you
	run "interpreter-exec console" when the top level interpreter is
	already the console/tui.  Like:

	 (gdb) interpreter-exec console "foobar"
	 Undefined command: "foobar".  Try "help".
	 error in command: "foobar".

	You won't see it with MI's "-interpreter-exec console" from a top
	level MI interpreter:

	 (gdb)
	 -interpreter-exec console "foobar"
	 &"Undefined command: \"foobar\".  Try \"help\".\n"
	 ^error,msg="Undefined command: \"foobar\".  Try \"help\"."
	 (gdb)

	nor with MI's "-interpreter-exec mi" from a top level MI interpreter:

	 (gdb)
	 -interpreter-exec mi "-foobar"
	 ^error,msg="Undefined MI command: foobar",code="undefined-command"
	 ^done
	 (gdb)

	in both these cases because MI's -interpreter-exec just does:

	  error ("%s", e.what ());

	You won't see it either when running an MI command with the CLI's
	"interpreter-exec mi":

	 (gdb) interpreter-exec mi "-foobar"
	 ^error,msg="Undefined MI command: foobar",code="undefined-command"
	 (gdb)

	This last case is because MI's interp::exec implementation never
	returns an error:

	 gdb_exception
	 mi_interp::exec (const char *command)
	 {
	   mi_execute_command_wrapper (command);
	   return gdb_exception ();
	 }

	Thus I think that "error in command" error is pretty pointless, and
	since it simplifies things to not have it, the patch just removes it.

	The patch also ends up addressing an old FIXME.

	Avoid FAILs in gdb.compile
	Many gdb.compile C++ tests fail for me on Fedora 36.  I think these
	are largely bugs in the plugin, though I didn't investigate too
	deeply.  Once one failure is seen, this often cascades and sometimes
	there are many timeouts.

	For example, this can happen:

	    (gdb) compile code var = a->get_var ()
	    warning: Could not find symbol "_ZZ9_gdb_exprP10__gdb_regsE1a" for compiled module "/tmp/gdbobj-0xdI6U/out2.o".
	    1 symbols were missing, cannot continue.

	I think this is probably a plugin bug because, IIRC, in theory these
	symbols should be exempt from a lookup via gdb.

	This patch arranges to catch any catastrophic failure and then simply
	exit the entire .exp file.

	Don't let .gdb_history file cause failures
	I had a .gdb_history file in my testsuite directory in the build tree,

	Merge fixup_section and fixup_symbol_section
	fixup_symbol_section delegates all its work to fixup_section, so merge
	the two.

	Because there is only a single caller to fixup_symbol_section, we can
	also remove some of the introductory logic.  For example, this will
	never be called with a NULL objfile any more.

	The LOC_BLOCK case can be removed, because such symbols are handled by
	the buildsym code now.

	Finally, a symbol can only appear in a SEC_ALLOC section, so the loop
	is modified to skip sections that do not have this flag set.

2023-02-08  Tom Tromey  <tromey@adacore.com>

	Remove most calls to fixup_symbol_section
	Nearly every call to fixup_symbol_section in gdb is incorrect, and if
	any such call has an effect, it's purely by happenstance.

	fixup_section has a long comment explaining that the call should only
	be made before runtime section offsets are applied.  And, the loop in
	this code (the fallback loop -- the minsym lookup code is "ok") is
	careful to remove these offsets before comparing addresses.

	However, aside from a single call in dwarf2/read.c, every call in gdb
	is actually done after section offsets have been applied.  So, these
	calls are incorrect.

	Now, these calls could be made when the symbol is created.  I
	considered this approach, but I reasoned that the code has been this
	way for many years, seemingly without ill effect.  So, instead I chose
	to simply remove the offending calls.

2023-02-08  Tom Tromey  <tromey@adacore.com>

	Set section index when setting a symbol's block
	When a symbol's block is set, the block has the runtime section offset
	applied.  So, it seems to me that the symbol implicitly is in the same
	section as the block.  Therefore, this patch sets the symbol's section
	index at this same spot.

	Remove compunit_symtab::m_block_line_section
	The previous patch hard-coded SECT_OFF_TEXT into the buildsym code.
	After this, it's clear that there is only one caller of
	compunit_symtab::set_block_line_section, and it always passes
	SECT_OFF_TEXT.  So, remove compunit_symtab::m_block_line_section and
	use SECT_OFF_TEXT instead.

	Do not pass section index to end_compunit_symtab
	Right now, the section index passed to end_compunit_symtab is always
	SECT_OFF_TEXT.  Remove this parameter and simply always use
	SECT_OFF_TEXT.

2023-02-08  Tom Tromey  <tromey@adacore.com>

	Set section indices when symbols are made
	Most places in gdb that create a new symbol will apply a section
	offset to the address.  It seems to me that the choice of offset here
	is also an implicit choice of the section.  This is particularly true
	if you examine fixup_section, which notes that it must be called
	before such offsets are applied -- meaning that if any such call has
	an effect, it's purely by accident.

	This patch cleans up this area by tracking the section index and
	applying it to a symbol when the address is set.  This is done for
	nearly every case -- the remaining cases will be handled in later
	patches.

2023-02-08  Tom Tromey  <tromey@adacore.com>

	Use default section indexes in fixup_symbol_section
	If fixup_section does not find a matching section, it arbitrarily
	chooses the first one.  However, it seems better to make this default
	depend on the type of the symbol -- i.e., default data symbols to
	.data and text symbols to .text.

	I've also made fixup_section static, as it only has one caller.

2023-02-08  Tom Tromey  <tom@tromey.com>

	Simplify checks of cooked_index
	This changes the cooked_index_functions to avoid an extra null check

	Fix this by using maint ignore-probes to simulate the absence of the relevant

	XFAIL: gdb.base/solib-corrupted.exp: make solibs looping
	UNTESTED: gdb.base/solib-corrupted.exp: no _r_debug symbol has been found

	This is incorrect, because an XFAIL indicates a known problem in the

	functioning as expected when glibc debuginfo is not installed.

	Fix this by using UNSUPPORTED instead, and make the message less cryptic:

	gdb: fix display of thread condition for multi-location breakpoints
	This commit addresses the issue in PR gdb/30087.

	If a breakpoint with multiple locations has a thread condition, then
	the 'info breakpoints' output is a little messed up, here's an example
	of the current output:

	  (gdb) break foo thread 1
	  Breakpoint 2 at 0x401114: foo. (3 locations)
	  (gdb) break bar thread 1
	  Breakpoint 3 at 0x40110a: file /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c, line 32.
	  (gdb) info breakpoints
	  Num     Type           Disp Enb Address            What
	  2       breakpoint     keep y   <MULTIPLE>          thread 1
	          stop only in thread 1
	  2.1                         y   0x0000000000401114 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
	  2.2                         y   0x0000000000401146 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
	  2.3                         y   0x0000000000401168 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
	  3       breakpoint     keep y   0x000000000040110a in bar at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:32 thread 1
	          stop only in thread 1

	Notice that, at the end of the location for breakpoint 3, the 'thread
	1' condition is printed, but this is then repeated on the next line
	with 'stop only in thread 1'.

	In contrast, for breakpoint 2, the 'thread 1' appears randomly, in the
	"What" column, though slightly offset, non of the separate locations
	have the 'thread 1' information.  Additionally for breakpoint 2 we
	also get a 'stop only in thread 1' line.

	There's two things going on here.  First the randomly placed 'thread
	1' for breakpoint 2 is due to a bug in print_one_breakpoint_location,
	where we check the variable part_of_multiple instead of
	header_of_multiple.

	If I fix this oversight, then the output is now:

	  (gdb) break foo thread 1
	  Breakpoint 2 at 0x401114: foo. (3 locations)
	  (gdb) break bar thread 1
	  Breakpoint 3 at 0x40110a: file /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c, line 32.
	  (gdb) info breakpoints
	  Num     Type           Disp Enb Address            What
	  2       breakpoint     keep y   <MULTIPLE>
	          stop only in thread 1
	  2.1                         y   0x0000000000401114 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25 thread 1
	  2.2                         y   0x0000000000401146 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25 thread 1
	  2.3                         y   0x0000000000401168 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25 thread 1
	  3       breakpoint     keep y   0x000000000040110a in bar at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:32 thread 1
	          stop only in thread 1

	The 'thread 1' condition is now displayed at the end of each location,
	which makes the output the same for single location breakpoints and
	multi-location breakpoints.

	However, there's still some duplication here.  Both breakpoints 2 and
	3 include a 'stop only in thread 1' line, and it feels like the
	additional 'thread 1' is redundant.  In fact, there's a comment to
	this very effect in the code:

	  /* FIXME: This seems to be redundant and lost here; see the
	     "stop only in" line a little further down.  */

	So, lets fix this FIXME.  The new plan is to remove all the trailing
	'thread 1' markers from the CLI output, we now get this:

	  (gdb) break foo thread 1
	  Breakpoint 2 at 0x401114: foo. (3 locations)
	  (gdb) break bar thread 1
	  Breakpoint 3 at 0x40110a: file /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c, line 32.
	  (gdb) info breakpoints
	  Num     Type           Disp Enb Address            What
	  2       breakpoint     keep y   <MULTIPLE>
	          stop only in thread 1
	  2.1                         y   0x0000000000401114 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
	  2.2                         y   0x0000000000401146 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
	  2.3                         y   0x0000000000401168 in foo at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:25
	  3       breakpoint     keep y   0x000000000040110a in bar at /tmp/src/gdb/testsuite/gdb.base/thread-bp-multi-loc.c:32
	          stop only in thread 1

	All of the above points are also true for the Ada 'task' breakpoint
	condition, and the changes I've made also update how the task
	information is printed, though in the case of the Ada task there was
	no 'stop only in task XXX' line printed, so I've added one of those.

	Obviously it can't be quite that easy.  For MI backwards compatibility
	I've retained the existing code (but now only for MI like outputs),
	which ensures we should generate backwards compatible output.

	I've extended an Ada test to cover the new task related output, and
	updated all the tests I could find that checked for the old output.

	(gdb) FAIL: gdb.threads/schedlock.exp: schedlock=on: cmd=continue: \
	  stop all threads (with lock) (timeout)
	...

	What happens is that this loop which is supposed to run "just short of forever":
	...
	    /* Don't run forever.  Run just short of it :)  */
	    while (*myp > 0)
	      {
	        /* schedlock.exp: main loop.  */
	        MAYBE_CALL_SOME_FUNCTION(); (*myp) ++;
	      }
	...
	finishes after 0x7fffffff iterations (when a signed wrap occurs), which on my
	system takes only about 1.5 seconds.

	Fix this by:
	- changing the pointed-at type of myp from signed to unsigned, which makes the
	  wrap defined behaviour (and which also make the loop run twice as long,
	  which is already enough to make it impossible for me to reproduce the FAIL.
	  But let's try to solve this more structurally).
	- changing the pointed-at type of myp from int to long long, making the wrap
	  unlikely.
	- making sure the loop runs forever, by setting the loop condition to 1.
	- making sure the loop still contains different lines (as far as debug info is
	  concerned) by incrementing a volatile counter in the loop.
	- making sure the program doesn't run forever in case of trouble, by adding an
	  "alarm (30)".

	Tested on x86_64-linux.

	gdb: error if 'thread' or 'task' keywords are overused
	When creating a breakpoint or watchpoint, the 'thread' and 'task'
	keywords can be used to create a thread or task specific breakpoint or
	watchpoint.

	Currently, a thread or task specific breakpoint can only apply for a
	single thread or task, if multiple threads or tasks are specified when
	creating the breakpoint (or watchpoint), then the last specified id
	will be used.

	The exception to the above is that when the 'thread' keyword is used
	during the creation of a watchpoint, GDB will give an error if
	'thread' is given more than once.

	In this commit I propose making this behaviour consistent, if the
	'thread' or 'task' keywords are used more than once when creating
	either a breakpoint or watchpoint, then GDB will give an error.

	I haven't updated the manual, we don't explicitly say that these
	keywords can be repeated, and (to me), given the keyword takes a
	single id, I don't think it makes much sense to repeat the keyword.
	As such, I see this more as adding a missing error to GDB, rather than
	making some big change.  However, I have added an entry to the NEWS
	file as I guess it is possible that some people might hit this new
	error with an existing (I claim, badly written) GDB script.

	I've added some new tests to check for the new error.

	Just one test needed updating, gdb.linespec/keywords.exp, this test
	did use the 'thread' keyword twice, and expected the breakpoint to be
	created.  Looking at what this test was for though, it was checking
	the use of '-force-condition', and I don't think that being able to
	repeat 'thread' was actually a critical part of this test.

	As such, I've updated this test to expect the error when 'thread' is
	repeated.

	Resetting section vma after _bfd_dwarf2_find_nearest_line
	There are failure paths in _bfd_dwarf2_slurp_debug_info that can
	result in altered section vmas.  Also, when setting ET_REL section
	vmas it's not too difficult to handle cases where the original vma was
	non-zero, so do that too.

	This patch was really in response to an addr2line buffer overflow
	processing a fuzzed mips relocatable object file.  The file had a
	number of .debug_info sections with relocations that included lo16 and
	hi16 relocs, and in that order.  At least one section VMA was
	non-zero.  This resulted in processing of DWARF info twice, once via
	the call to _bfd_dwarf2_find_nearest_line in
	_bfd_mips_elf_find_nearest_line, and because that failed leaving VMAs
	altered, the second via the call in _bfd_elf_find_nearest_line.  The
	first call left entries on mips_hi16_list pointing at buffers
	allocated during the first call, the second call processed the
	mips_hi16_list after the buffers had been freed.  (At least when
	running with asan and under valgrind.  Under gdb with a non-asan
	addr2line the second call allocated exactly the same buffer and the
	bug didn't show.)  Now I don't really care too much what happens with
	fuzzed files, but the logic in _bfd_dwarf2_find_nearest_line is meant
	to result in only one read of .debug_info, not multiple reads of the
	same info when there are errors.  This patch fixes that problem.

		* dwarf2.c (struct adjusted_section): Add orig_vma.
		(unset_sections): Reset vma to it.
		(place_sections): Handle non-zero vma too.  Save orig_vma.
		(_bfd_dwarf2_slurp_debug_info): Tidy.  Correct outdated comment.
		On error returns after calling place_sections, call
		unset_sections.
		(_bfd_dwarf2_find_nearest_line_with_alt): Simplify call to
		unset_sections.

	gdb/testsuite: don't try to set non-stop mode on a running target
	The test gdb.threads/thread-specific-bp.exp tries to set non-stop mode
	on a running target, something which the manual makes clear is not
	allowed.

	This commit restructures the test a little, we now set the non-stop
	mode as part of the GDBFLAGS, so the mode will be set before GDB
	connects to the target.  As a consequence I'm able to move the
	with_test_prefix out of the check_thread_specific_breakpoint proc.
	The check_thread_specific_breakpoint proc is now called within a loop.

	After this commit the gdb.threads/thread-specific-bp.exp test still
	has some failures, this is because of an issue GDB currently has
	printing "Thread ... exited" messages.  This problem should be
	addressed by this patch:

	ld: pru: Add optional section alignments
	The Texas Instruments SoCs with AARCH64 host processors have stricter
	alignment requirements than ones with ARM32 host processors.  It's not
	only the requirement for resource_table to be aligned to 8.  But also
	any loadable segment size must be a multiple of 4 [1].

	The current PRU default linker script may output a segment size not
	aligned to 4, which would cause firmware load failure on AARCH64 hosts.

	Fix this by using COMMONPAGESIZE and MAXPAGESIZE to signify respectively
	the section memory size requirement and the resource table section's
	start address alignment.  This would avoid penalizing the ARM32 hosts,
	for which the default values (1 and 1) are sufficient.

	For AARCH64 hosts, the alignments would be overwritten from GCC spec
	files using the linker command line, e.g.:
	  -z common-page-size=4 -z max-page-size=8

	[1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/remoteproc/pru_rproc.c?h=v6.1#n555

	ld/ChangeLog:

		* scripttempl/pru.sc (_data_end): Remove the alignment.
		(.data): Align output section size to COMMONPAGESIZE.
		(.resource_table): Ditto.

	ld: pru: Merge the bss input sections into data
	The popular method to load PRU firmware is through the remoteproc Linux
	kernel driver.  In order to save a few bytes from the firmware, the PRU
	CRT0 is spared from calling memset for the bss segment [1].  Instead the
	host loader is supposed to zero out the bss segment.  This is important
	for PRU, which typically has only 8KB for instruction memory.

	The legacy non-mainline PRU host driver relied on the default
	behaviour of the kernel core remoteproc [2].  That default is to zero
	out the loadable memory regions not backed by file storage (i.e. the
	bss sections).  This worked for the libgloss' CRT0.

	But the PRU loader merged in mainline Linux explicitly changes the
	default behaviour [3].  It no longer is zeroing out memory regions.
	Hence the bss sections are not initialized - neither by CRT0, nor by the
	host loader.

	This patch fixes the issue by aligning the GNU LD default linker script
	with the mainline Linux kernel expectation.  Since the mainline kernel
	driver is submitted by the PRU manufacturer itself (Text Instruments),
	we can consider that as defining the ABI.

	This change has been tested on Beaglebone AI-64 [4].  Static counter
	variables in the firmware are now always starting from zero, as
	expected.  There was only one new toolchain test failure in orphan3.d,
	due to reordering of the output sections.  I believe this is a harmless
	issue.  I could not rewrite the PASS criteria to ignore the output
	section ordering, so I have disabled that test case for PRU.

	gdb: initial support for ROCm platform (AMDGPU) debugging
	This patch adds the foundation for GDB to be able to debug programs
	offloaded to AMD GPUs using the AMD ROCm platform [1].  The latest
	public release of the ROCm release at the time of writing is 5.4, so
	this is what this patch targets.

	The ROCm platform allows host programs to schedule bits of code for
	execution on GPUs or similar accelerators.  The programs running on GPUs
	are typically referred to as `kernels` (not related to operating system
	kernels).

	Programs offloaded with the AMD ROCm platform can be written in the HIP
	language [2], OpenCL and OpenMP, but we're going to focus on HIP here.
	The HIP language consists of a C++ Runtime API and kernel language.
	Here's an example of a very simple HIP program:

	    #include "hip/hip_runtime.h"
	    #include <cassert>

	    __global__ void
	    do_an_addition (int a, int b, int *out)
	    {
	      *out = a + b;
	    }

	    int
	    main ()
	    {
	      int *result_ptr, result;

	      /* Allocate memory for the device to write the result to.  */
	      hipError_t error = hipMalloc (&result_ptr, sizeof (int));
	      assert (error == hipSuccess);

	      /* Run `do_an_addition` on one workgroup containing one work item.  */
	      do_an_addition<<<dim3(1), dim3(1), 0, 0>>> (1, 2, result_ptr);

	      /* Copy result from device to host.  Note that this acts as a synchronization
	         point, waiting for the kernel dispatch to complete.  */
	      error = hipMemcpyDtoH (&result, result_ptr, sizeof (int));
	      assert (error == hipSuccess);

	      printf ("result is %d\n", result);
	      assert (result == 3);

	      return 0;
	    }

	This program can be compiled with:

	    $ hipcc simple.cpp -g -O0 -o simple

	... where `hipcc` is the HIP compiler, shipped with ROCm releases.  This
	generates an ELF binary for the host architecture, containing another
	ELF binary with the device code.  The ELF for the device can be
	inspected with:

	    $ roc-obj-ls simple
	    1       host-x86_64-unknown-linux                                           file://simple#offset=8192&size=0
	    1       hipv4-amdgcn-amd-amdhsa--gfx906                                     file://simple#offset=8192&size=34216
	    $ roc-obj-extract 'file://simple#offset=8192&size=34216'
	    $ file simple-offset8192-size34216.co
	    simple-offset8192-size34216.co: ELF 64-bit LSB shared object, *unknown arch 0xe0* version 1, dynamically linked, with debug_info, not stripped
	                                                                                 ^
	                       amcgcn architecture that my `file` doesn't know about ----´

	Running the program gives the very unimpressive result:

	    $ ./simple
	    result is 3

	While running, this host program has copied the device program into the
	GPU's memory and spawned an execution thread on it.  The goal of this
	GDB port is to let the user debug host threads and these GPU threads
	simultaneously.  Here's a sample session using a GDB with this patch
	applied:

	think of the threads running on the GPU as part of the same program as
	the host threads, so showing them in the same inferior in GDB seems
	natural.  Also, the host and GPU threads share a global memory space,
	which fits the inferior model.

	Another thing to notice is the error messages when trying to read
	variables or printing a backtrace.  This is expected for the moment,
	since the AMD GPU compiler produces some DWARF that uses some
	non-standard extensions:

	  https://llvm.org/docs/AMDGPUDwarfExtensionsForHeterogeneousDebugging.html

	There were already some patches posted by Zoran Zaric earlier to make
	GDB support these extensions:

	  https://inbox.sourceware.org/gdb-patches/20211105113849.118800-1-zoran.zaric@amd.com/

	We think it's better to get the basic support for AMD GPU in first,
	which will then give a better justification for GDB to support these
	extensions.

	GPU threads are named `AMDGPU Wave`: a wave is essentially a hardware
	thread using the SIMT (single-instruction, multiple-threads) [3]
	execution model.

	GDB uses the amd-dbgapi library [4], included in the ROCm platform, for
	a few things related to AMD GPU threads debugging.  Different components
	talk to the library, as show on the following diagram:

	    +---------------------------+     +-------------+     +------------------+
	    | GDB   | amd-dbgapi target | <-> |     AMD     |     |    Linux kernel  |
	    |       +-------------------+     |   Debugger  |     +--------+         |
	    |       | amdgcn gdbarch    | <-> |     API     | <=> | AMDGPU |         |
	    |       +-------------------+     |             |     | driver |         |
	    |       | solib-rocm        | <-> | (dbgapi.so) |     +--------+---------+
	    +---------------------------+     +-------------+

	  - The amd-dbgapi target is a target_ops implementation used to control
	    execution of GPU threads.  While the debugging of host threads works
	    by using the ptrace / wait Linux kernel interface (as usual), control
	    of GPU threads is done through a special interface (dubbed `kfd`)
	    exposed by the `amdgpu` Linux kernel module.  GDB doesn't interact
	    directly with `kfd`, but instead goes through the amd-dbgapi library
	    (AMD Debugger API on the diagram).

	    Since it provides execution control, the amd-dbgapi target should
	    normally be a process_stratum_target, not just a target_ops.  More
	    on that later.

	  - The amdgcn gdbarch (describing the hardware architecture of the GPU
	    execution units) offloads some requests to the amd-dbgapi library,
	    so that knowledge about the various architectures doesn't need to be
	    duplicated and baked in GDB.  This is for example for things like
	    the list of registers.

	  - The solib-rocm component is an solib provider that fetches the list of
	    code objects loaded on the device from the amd-dbgapi library, and
	    makes GDB read their symbols.  This is very similar to other solib
	    providers that handle shared libraries, except that here the shared
	    libraries are the pieces of code loaded on the device.

	Given that Linux host threads are managed by the linux-nat target, and
	the GPU threads are managed by the amd-dbgapi target, having all threads
	appear in the same inferior requires the two targets to be in that
	inferior's target stack.  However, there can only be one
	process_stratum_target in a given target stack, since there can be only
	one target per slot.  To achieve it, we therefore resort the hack^W
	solution of placing the amd-dbgapi target in the arch_stratum slot of
	the target stack, on top of the linux-nat target.  Doing so allows the
	amd-dbgapi target to intercept target calls and handle them if they
	concern GPU threads, and offload to beneath otherwise.  See
	amd_dbgapi_target::fetch_registers for a simple example:

	    void
	    amd_dbgapi_target::fetch_registers (struct regcache *regcache, int regno)
	    {
	      if (!ptid_is_gpu (regcache->ptid ()))
	        {
	          beneath ()->fetch_registers (regcache, regno);
	          return;
	        }

	      // handle it
	    }

	ptids of GPU threads are crafted with the following pattern:

	  (pid, 1, wave id)

	Where pid is the inferior's pid and "wave id" is the wave handle handed
	to us by the amd-dbgapi library (in practice, a monotonically
	incrementing integer).  The idea is that on Linux systems, the
	combination (pid != 1, lwp == 1) is not possible.  lwp == 1 would always
	belong to the init process, which would also have pid == 1 (and it's
	improbable for the init process to offload work to the GPU and much less
	for the user to debug it).  We can therefore differentiate GPU and
	non-GPU ptids this way.  See ptid_is_gpu for more details.

	Note that we believe that this scheme could break down in the context of
	containers, where the initial process executed in a container has pid 1
	(in its own pid namespace).  For instance, if you were to execute a ROCm
	program in a container, then spawn a GDB in that container and attach to
	the process, it will likely not work.  This is a known limitation.  A
	workaround for this is to have a dummy process (like a shell) fork and
	execute the program of interest.

	The amd-dbgapi target watches native inferiors, and "attaches" to them
	using amd_dbgapi_process_attach, which gives it a notifier fd that is
	registered in the event loop (see enable_amd_dbgapi).  Note that this
	isn't the same "attach" as in PTRACE_ATTACH, but being ptrace-attached
	is a precondition for amd_dbgapi_process_attach to work.  When the
	debugged process enables the ROCm runtime, the amd-dbgapi target gets
	notified through that fd, and pushes itself on the target stack of the
	inferior.  The amd-dbgapi target is then able to intercept target_ops
	calls.  If the debugged process disables the ROCm runtime, the
	amd-dbgapi target unpushes itself from the target stack.

	This way, the amd-dbgapi target's footprint stays minimal when debugging
	a process that doesn't use the AMD ROCm platform, it does not intercept
	target calls.

	The amd-dbgapi library is found using pkg-config.  Since enabling
	support for the amdgpu architecture (amdgpu-tdep.c) depends on the
	amd-dbgapi library being present, we have the following logic for
	the interaction with --target and --enable-targets:

	 - if the user explicitly asks for amdgcn support with
	   --target=amdgcn-*-* or --enable-targets=amdgcn-*-*, we probe for
	   the amd-dbgapi and fail if not found

	 - if the user uses --enable-targets=all, we probe for amd-dbgapi,
	   enable amdgcn support if found, disable amdgcn support if not found

	 - if the user uses --enable-targets=all and --with-amd-dbgapi=yes,
	   we probe for amd-dbgapi, enable amdgcn if found and fail if not found

	 - if the user uses --enable-targets=all and --with-amd-dbgapi=no,
	   we do not probe for amd-dbgapi, disable amdgcn support

	 - otherwise, amd-dbgapi is not probed for and support for amdgcn is not
	   enabled

	Finally, a simple test is included.  It only tests hitting a breakpoint
	in device code and resuming execution, pretty much like the example
	shown above.

	gdb/solib-svr4: don't disable probes interface if probe not found
	In ROCm-GDB, we install an solib provider for the GPU code objects on
	top of the svr4 provider for the host, in order to add solibs
	representing the GPU code objects to the solib list containing the host
	process' shared libraries.  We override the target_so_ops::handle_event
	function pointer with our own, in which we call svr4_so_ops.handle_event
	(which contains svr4_handle_solib_event) manually.  When the host
	(un)loads a library, the ROCm part of handle_event is a no-op.  When the
	GPU (un)loads a code object, we want the host side (svr4) to be a no-op.

	The problem is that when handle_event is called because of a GPU event,
	svr4_handle_solib_event gets called while not stopped at an svr4
	probe.  It then assumes this means there's a problem with the probes
	interface and disables it through the following sequence of events:

	  - solib_event_probe_at return nullptr
	  - svr4_handle_solib_event returns early
	  - the make_scope_exit callback calls disable_probes_interface

	We could fix that by making the ROCm handle_event callback check if an
	svr4 probe is that the stop address, and only call
	svr4_so_ops.handle_event if so.  However, it doesn't feel right to
	include some svr4 implementation detail in the ROCm event handler.

	Instead, this patch changes svr4_handle_solib_event to not assume it is
	an error if called while not at an svr4 probe location, and therefore
	not disable the probes interface.  That just means moving the
	make_scope_exit call below where we lookup the probe by pc.

	The problem is that the above commit introduces a direct use of the

	exercised by the native-gdbserver board.

	To avoid this, in this commit I switch to using runto_main.  However,

	we need to avoid this breakpoint deleting behaviour.

	To do this I make use of with_override, and override the
	delete_breakpoints proc with a dummy proc which does nothing.

	By reverting the GDB changes in commit 7dd38e31d67c I have confirmed
	that even after my changes in this commit, the test still fails.  But

	gdb: defer warnings when loading separate debug files
	Currently, when GDB loads debug information from a separate debug
	file, there are a couple of warnings that could be produced if things
	go wrong.

	In find_separate_debug_file_by_buildid (build-id.c) GDB can give a
	warning if the separate debug file doesn't include any actual debug
	information, and in separate_debug_file_exists (symfile.c) we can warn
	if the CRC checksum in the separate debug file doesn't match the
	checksum in the original executable.

	The problem here is that, when looking up debug information, GDB will
	try several different approaches, lookup by build-id, lookup by
	debug-link, and then a lookup from debuginfod.  GDB can potentially
	give a warning from an earlier attempt, and then succeed with a later
	attempt.  In the cases I have run into this is primarily a warning
	about some out of date debug information on my machine, but then GDB
	finds the correct information using debuginfod.  This can be confusing
	to a user, they will see warnings from GDB when really everything is
	working just fine.

	For example:

	  warning: the debug information found in "/usr/lib/debug//lib64/ld-2.32.so.debug" \
	      does not match "/lib64/ld-linux-x86-64.so.2" (CRC mismatch).

	This diagnostic was printed on Fedora 33 even when the correct
	debuginfo was downloaded.

	In this patch I propose that we defer any warnings related to looking
	up debug information from a separate debug file.  If any of the
	approaches are successful then GDB will not print any of the warnings.
	As far as the user is concerned, everything "just worked".  Only if
	GDB completely fails to find any suitable debug information will the
	warnings be printed.

	The crc_mismatch test compiles two executables: crc_mismatch and
	crc_mismatch-2 and then strips them of debuginfo creating separate
	debug files. The test then replaces crc_mismatch-2.debug with
	crc_mismatch.debug to trigger "CRC mismatch" warning. A local
	debuginfod server is setup to supply the correct debug file, now when
	GDB looks up the debug info no warning is given.

	The build-id-no-debug-warning.exp is similar to the previous test. It
	triggers the "separate debug info file has no debug info" warning by
	replacing the build-id based .debug file with the stripped binary and
	then loading it to GDB.  It then also sets up local debuginfod server
	with the correct debug file to download to make sure no warnings are
	emitted.

	gdb/dwarf: rename cooked_index to cooked_index_shard
	I propose to rename cooked_index_vector and cooked_index such that the
	"main" object, that is the entry point to the index, is called
	cooked_index.  The fact that the cooked index is implemented as a vector
	of smaller indexes is an implementation detail.

	This patch renames cooked_index to cooked_index_shard.  The following
	patch renames cooked_index_vector to cooked_index.

	The problem is that when cooked_index_functions fails to build an index,
	per_objfile->index_table is nullptr.  Therefore, add a nullptr check,
	like other methods of cooked_index_functions already do.

	Print the "Cooked index in use" message after the nullptr check, such
	that if the cooked index failed to build, that message is not printed.

	gdb/dwarf: dump cooked index contents in cooked_index_functions::dump
	As I am investigating a crash I see with the cooked index, I thought it
	would be useful to have a way to dump the index contents.  For those not
	too familiar with it (that includes me), it can help get a feel of what
	it contains and how it is structured.

	The cooked_index_functions::dump function is called as part of the
	"maintenance print objfiles" command.  I tried to make the output
	well structured and indented to help readability, as this prints a lot
	of text.

	The dump function first dumps all cooked index entries, like this:

	    [25] ((cooked_index_entry *) 0x621000121220)
	    name:       __ioinit
	    canonical:  __ioinit
	    DWARF tag:  DW_TAG_variable
	    flags:      0x2 [IS_STATIC]
	    DIE offset: 0x21a4
	    parent:     ((cooked_index_entry *) 0x6210000f9610) [std]

	Then the information about the main symbol:

	    main: ((cooked_index_entry *) 0x621000123b40) [main]

	And finally the address map contents:

	    [1] ((addrmap *) 0x6210000f7910)

	      [0x0] ((dwarf2_per_cu_data *) 0)
	      [0x118a] ((dwarf2_per_cu_data *) 0x60c000007f00)
	      [0x1cc7] ((dwarf2_per_cu_data *) 0)
	      [0x1cc8] ((dwarf2_per_cu_data *) 0x60c000007f00)
	      [0x1cdf] ((dwarf2_per_cu_data *) 0)
	      [0x1ce0] ((dwarf2_per_cu_data *) 0x60c000007f00)

	The display of address maps above could probably be improved, to show it
	more as ranges, but I think this is a reasonable start.

	Note that this patch depends on Pedro Alves' patch "enum_flags
	to_string" [1].  If my patch is to be merged before Pedro's series, I
	will cherry-pick this patch from his series and merge it before mine.

	enum_flags to_string
	This commit introduces shared infrastructure that can be used to
	implement enum_flags -> to_string functions.  With this, if we want to
	support converting a given enum_flags specialization to string, we
	just need to implement a function that provides the enumerator->string
	mapping, like so:

	 enum some_flag
	   {
	     SOME_FLAG1 = 1 << 0,
	     SOME_FLAG2 = 1 << 1,
	     SOME_FLAG3 = 1 << 2,
	   };

	 DEF_ENUM_FLAGS_TYPE (some_flag, some_flags);

	 static std::string
	 to_string (some_flags flags)
	 {
	   static constexpr some_flags::string_mapping mapping[] = {
	     MAP_ENUM_FLAG (SOME_FLAG1),
	     MAP_ENUM_FLAG (SOME_FLAG2),
	     MAP_ENUM_FLAG (SOME_FLAG3),
	   };
	   return flags.to_string (mapping);
	 }

	.. and then to_string(SOME_FLAG2 | SOME_FLAG3) produces a string like
	"0x6 [SOME_FLAG2 SOME_FLAG3]".

	If we happen to forget to update the mapping array when we introduce a
	new enumerator, then the string representation will pretty-print the
	flags it knows about, and then the leftover flags in hex (one single
	number).  For example, if we had missed mapping SOME_FLAG2 above, we'd
	end up with:

	  to_string(SOME_FLAG2 | SOME_FLAG3)  => "0x6 [SOME_FLAG2 0x4]");

	Other than in the unit tests included, no actual usage of the
	functionality is added in this commit.

	Fix comparator bug in cooked index
	Simon pointed out that the cooked index template-matching patch
	introduced a failure in libstdc++ debug mode.  In particular, the new
	code violates the assumption of std::lower_bound and std::upper_bound
	that the range is sorted with respect to the comparison.

	When I first debugged this, I thought the problem was unfixable as-is
	and that a second layer of filtering would have to be done.  However,
	on irc, Simon pointed out that it could perhaps be solved if the
	comparison function were assured that one operand always came from the
	index, with the other always being the search string.

	This patch implements this idea.

	First, a new mode is introduced: a sorting mode for
	cooked_index_entry::compare.  In this mode, strings are compared
	case-insensitively, but we're careful to always sort '<' before any
	other printable character.  This way, two names like "func" and
	"func<param>" will be sorted next to each other -- i.e., "func1" will
	not be seen between them.  This is important when searching.

	Second, the compare function is changed to work in a strcmp-like way.
	This makes it easier to test and (IMO) understand.

	Third, the compare function is modified so that in non-sorting modes,
	the index entry is always the first argument.  This allows consistency
	in compares.

	I regression tested this in libstdc++ debug mode on x86-64 Fedora 36.
	It fixes the crash that Simon saw.

	This is v2.  I believe it addresses the review comments, except for
	the 'enum class' change, as I mentioned in email on the list.

	gdb: provide const-correct versions of addrmap::find and addrmap::foreach
	Users of addrmap::find and addrmap::foreach that have a const addrmap
	should ideally receive const pointers to objects, to indicate they
	should not be modified.  However, users that have a non-const addrmap
	should still receive a non-const pointer.

	To achieve this, without adding more virtual methods, make the existing
	find and foreach virtual methods private and prefix them with "do_".
	Add small non-const and const wrappers for find and foreach.

	Obviously, the const can be cast away, but if using static_cast
	instead of C-style casts, then the compiler won't let you cast
	the const away.  I changed all the callers of addrmap::find and
	addrmap::foreach I could find to make them use static_cast.

	gdb: Add per-remote target variables for memory read and write config
	This patch adds per-remote target variables for the configuration of
	memory read- and write packet size.  It is a further change to commit
	"gdb: Make global feature array a per-remote target array" to apply the
	fixme notes described in commit 5b6d1e4 "Multi-target support".

	The former global variables for that configuration are still available
	to allow the command line configuration for all future remote
	connections.  Similar to the command line configuration of the per-
	remote target feature array, the commands

	- set remotewritesize (deprecated)
	- set remote memory-read-packet-size
	- set remote memory-write-packet-size

	will configure the current target (if available).  If no target is
	available, the default configuration for future remote connections is
	adapted.  The show command will display the current remote target's
	packet size configuration.  If no remote target is selected, the default
	configuration for future connections will be shown.

	It is required to adapt the test gdb.base/remote.exp which is failing
	for --target_board=native-extended-gdbserver.  With that board GDB
	connects to gdbserver at gdb start time.  Due to this patch two loggings
	"The target may not be able to.." are shown if the command 'set remote
	memory-write-packet-size fixed' is executed while a target is connected
	for the current inferior.  To fix this, the clean_restart command is
	moved to a later time point of the test.  It is sufficient to be
	connected to the server when "runto_main" is executed.  Now the
	connection time is similar to a testrun with
	--target_board=native-gdbserver.

	To allow the user to distinguish between the packet-size configuration
	for future remote connections and for the currently selected target, the
	commands' loggings are adapted.

	"You'll notice that remote.c includes some FIXME notes.  These refer to
	the fact that the global arrays that hold data for the remote packets
	supported are still globals.  For example, if we connect to two
	different servers/stubs, then each might support different remote
	protocol features.  They might even be different architectures, like
	e.g., one ARM baremetal stub, and a x86 gdbserver, to debug a
	host/controller scenario as a single program.  That isn't going to
	work correctly today, because of said globals.  I'm leaving fixing
	that for another pass, since it does not appear to be trivial, and I'd
	rather land the base work first.  It's already useful to be able to
	debug multiple instances of the same server (e.g., a distributed
	cluster, where you have full control over the servers installed), so I
	think as is it's already reasonable incremental progress."

	Using this patch it is possible to configure per-remote targets'
	feature packets.

	Given the following setup for two gdbservers:

	~~~~
	gdbserver --multi :1234
	gdbserver --disable-packet=vCont --multi :2345
	~~~~

	Before this patch configuring of range-stepping was not possible for one
	of two connected remote targets with different support for the vCont
	packet.  As one of the targets supports vCont, it should be possible to
	configure "set range-stepping".  However, the output of GDB looks like:

	(gdb) target extended-remote :1234
	Remote debugging using :1234
	(gdb) add-inferior -no-connection
	[New inferior 2]
	Added inferior 2
	(gdb) inferior 2
	[Switching to inferior 2 [<null>] (<noexec>)]
	(gdb) target extended-remote :2345
	Remote debugging using :2345
	(gdb) set range-stepping on
	warning: Range stepping is not supported by the current target
	(gdb) inferior 1
	[Switching to inferior 1 [<null>] (<noexec>)]
	(gdb) set range-stepping on
	warning: Range stepping is not supported by the current target
	~~~~

	Two warnings are shown.  The warning for inferior 1 should not appear
	as it is connected to a target supporting the vCont package.

	~~~~
	(gdb) target extended-remote :1234
	Remote debugging using :1234
	(gdb) add-inferior -no-connection
	[New inferior 2]
	Added inferior 2
	(gdb) inferior 2
	[Switching to inferior 2 [<null>] (<noexec>)]
	(gdb) target extended-remote :2345
	Remote debugging using :2345
	(gdb) set range-stepping on
	warning: Range stepping is not supported by the current target
	(gdb) inferior 1
	[Switching to inferior 1 [<null>] (<noexec>)]
	(gdb) set range-stepping on
	(gdb)
	~~~~

	Now only one warning is shown for inferior 2, which is connected to
	a target not supporting vCont.

	The per-remote target feature array is realized by a new class
	remote_features, which stores the per-remote target array and
	provides functions to determine supported features of the target.
	A remote_target object now has a new member of that class.

	Each time a new remote_target object is initialized, a new per-remote
	target array is constructed based on the global remote_protocol_packets
	array.  The global array is initialized in the function _initialize_remote
	and can be configured using the command line.  Before this patch the
	command line configuration affected current targets and future remote
	targets (due to the global feature array used by all remote
	targets).  This behavior is different and the configuration applies as
	follows:

	 - If a target is connected, the command line configuration affects the
	   current connection.  All other existing remote targets are not
	   affected.

	 - If not connected, the command line configuration affects future
	   connections.

	The show command displays the current remote target's configuration.  If no
	remote target is selected the default configuration for future
	connections is shown.

	If we have for instance the following setup with inferior 2 being
	selected:
	~~~~
	(gdb) info inferiors
	  Num  Description       Connection                Executable
	  1    <null>             1 (extended-remote :1234)
	* 2    <null>             2 (extended-remote :2345)
	~~~~

	Before this patch, if we run 'set remote multiprocess-feature-packet', the
	following configuration was set:
	The feature array of all remote targets (in this setup the two connected
	targets) and all future remote connections are affected.

	After this patch, it will be configured as follows:
	The feature array of target with port :2345 which is currently selected
	will be configured.  All other existing remote targets are not affected.
	The show command 'show remote multiprocess-feature-packet' will display
	the configuration of target with port :2345.

	Due to this configuration change, it is required to adapt the test
	"gdb/testsuite/gdb.multi/multi-target-info-inferiors.exp" to configure the
	multiprocess-feature-packet before the connections are created.

	To inform the gdb user about the new behaviour of the 'show remote
	PACKET-NAME' commands and the new configuration impact for remote
	targets using the 'set remote PACKET-NAME' commands the commands'
	outputs are adapted.  Due to this change it is required to adapt each
	test using the set/show remote 'PACKET-NAME' commands.

	Recent commit 1d98e564c97 ("[gdb/testsuite] Add

	in the sense that gdb.base/unwind-on-each-insn.exp no longer uses

	which should instead be:
	...
	    lappend srcfile2_flags {*}$nodebug_flags

	gdb/tui: avoid extra refresh_window on vertical scroll
	While working on the previous couple of patches I noticed that when I
	scroll the src and asm windows vertically, I get two refresh_window
	calls.

	The two calls can be traced back to
	tui_source_window_base::update_source_window_as_is, in here we call
	show_source_content, which calls refresh_window, and then
	update_exec_info, which also calls refresh_window.

	In this commit I propose making the refresh_window call in
	update_exec_info optional.  In update_source_window_as_is I'll then
	call update_exec_info before calling show_source_content, and pass a
	flag to update_exec_info to defer the refresh.

	There are places where update_exec_info is used without any subsequent
	refresh_window call (e.g. when a breakpoint is updated), so
	update_exec_info does not to call refresh_window in some cases, which
	is why I'm using a flag to control the refresh.

	With this changes I'm now only seeing a single refresh_window call for
	each vertical scroll.

	There should be no user visible changes after this commit.

	gdb/tui: avoid extra refresh_window on horizontal scroll
	While working on the previous patches I noticed that in some cases I
	was seeing two calls to tui_source_window_base::refresh_window when
	scrolling the window horizontally.

	The two calls would trigger in for the tui-disasm-long-lines.exp test
	when the pad needed to be refilled.  The two called both come from
	tui_source_window_base::show_source_content.  The first call is nested
	within check_and_display_highlight_if_needed, while the second call is
	done directly at the end of show_source_content.

	The check_and_display_highlight_if_needed is being used to draw the
	window box to the window, this is needed here because
	show_source_content is what gets called when the window needs
	updating, e.g. after a resize.  We could potentially do the boxing in
	refresh_window, but then we'd be doing it each time we scroll, even
	though the box doesn't need changing in this case.

	However, we can move the check_and_display_highlight_if_needed to be
	the last thing done in show_source_content, this means that we can
	rely on the refresh_window call within it to be our single refresh
	call.

	There should be no user visible changes after this commit.

	gdb/tui: rewrite of tui_source_window_base to handle very long lines
	This commit addresses an issue that is exposed by the test script
	gdb.tui/tui-disasm-long-lines.exp, that is, tui_source_window_base
	does not handle very long lines.

	The problem can be traced back to the newpad call in
	tui_source_window_base::show_source_content, this is where we allocate
	a backing pad to hold the window content.

	Unfortunately, there appears to be a limit to the size of pad that can
	be allocated, and the gdb.tui/tui-disasm-long-lines.exp test goes
	beyond this limit.  As a consequence the newpad call fails and returns
	nullptr.

	It just so happens that the reset of the tui_source_window_base code
	can handle the pad being nullptr (this happens anyway when the window
	is first created, so we already depend on nullptr handling), so all
	that happens is the source window displays no content.

	... well, sort of ... something weird does happen in the command
	window, we seem to see a whole bunch of blank lines.  I've not
	bothered to track down exactly what's happening there, but it's some
	consequence of GDB attempting to write content to a WINDOW* that is
	nullptr.

	Before explaining my solution, I'll outline how things currently work:

	Consider we have the following window content to display:

	  aaaaaaaaaa
	  bbbbbbbbbbbbbbbbbbbb
	  ccccccccccccccc

	the longest line here is 20 characters.  If our display window is 10
	characters wide, then we will create a pad that is 20 characters wide,
	and then copy the lines of content into the pad:

	  .--------------------.
	  |aaaaaaaaaa          |
	  |bbbbbbbbbbbbbbbbbbbb|
	  |ccccccccccccccc     |
	  .--------------------.

	Now we will copy a 10 character wide view into this pad to the
	display, our display will then see:

	  .----------.
	  |aaaaaaaaaa|
	  |bbbbbbbbbb|
	  |cccccccccc|
	  .----------.

	As the user scrolls left and right we adjust m_horizontal_offset and
	use this to select which part of the pad is copied onto the display.

	The benefit of this is that we only need to copy the content to the
	pad once, which includes processing the ansi escape sequences, and
	then the user can scroll left and right as much as they want
	relatively cheaply.

	The problem then, is that if the longest content line is very long,
	then we try to allocate a very large pad, which can fail.

	What I propose is that we allow both the pad and the display view to
	scroll.  Once we allow this, then it becomes possible to allocate a
	pad that is smaller than the longest display line.  We then copy part
	of the content into the pad.  As the user scrolls the view left and
	right GDB will continue to copy content from the pad just as it does
	right now.  But, when the user scrolls to the edge of the pad, GDB
	will copy a new block of content into the pad, and then update the
	view as normal.  This all works fine so long as the maximum pad size
	is larger than the current window size - which seems a reasonable
	restriction, if ncurses can't support a pad of a given size it seems
	likely it will not support a display window of that size either.

	If we return to our example above, but this time we assume that the
	maximum pad size is 15 characters, then initially the pad would be
	loaded like this:

	  .---------------.
	  |aaaaaaaaaa     |
	  |bbbbbbbbbbbbbbb|
	  |ccccccccccccccc|
	  .---------------.

	Notice that the last 5 characters from the 'b' line are no longer
	included in the pad.  There is still enough content though to fill the
	10 character wide display, just as we did before.

	The pad contents remain unchanged until the user scrolls the display
	right to this point:

	  .----------.
	  |aaaaa     |
	  |bbbbbbbbbb|
	  |cccccccccc|
	  .----------.

	Now, when the user scrolls right once more GDB spots that the user has
	reached the end of the pad, and the pad contents are reloaded, like
	this:

	  .---------------.
	  |aaaaa          |
	  |bbbbbbbbbbbbbbb|
	  |cccccccccc     |
	  .---------------.

	The display can now be updated from the pad again just like normal.

	With this change in place the gdb.tui/tui-disasm-long-lines.exp test
	now correctly loads the assembler code, and we can scroll around as
	expected.

	Most of the changes are pretty mundane, just updating to match the
	above.  One interesting change though is the new member function
	tui_source_window_base::puts_to_pad_with_skip.  This replaces direct
	calls to tui_puts when copying content to the pad.

	The content strings contain ansi escape sequences.  When these strings
	are written to the pad these escape sequences are translated into
	ncurses attribute setting calls.

	Now however, we sometimes only write a partial string to the pad,
	skipping some of the leading content.  Imagine then that we have a
	content line like this:

	  "\033[31mABCDEFGHIJKLM\033[0m"

	Now the escape sequences in this content mean that the actual
	content (the 'ABCDEFGHIJKLM') will have a red foreground color.

	If we want to copy this to the pad, but skip the first 3 characters,
	then what we expect is to have the pad contain 'DEFGHIJKLM', but this
	text should still have a red foreground color.

	It is this problem that puts_to_pad_with_skip solves.  This function
	skips some number of printable characters, but processes all the
	escape sequences.  This means that when we do start printing the
	actual content the content will have the expected attributes.

	gdb/tui: make m_horizontal_offset private
	I noticed that tui_source_window_base::m_horizontal_offset was
	protected, but could be made private, so lets do that.

	This makes more sense in the context of a later commit where I plan to
	add another member variable that is similar to m_horizontal_offset.
	The new member variable could also be private.

	So I had to choose, place the new member variable next to
	m_horizontal_offset making it protected, but grouping similar
	variables together, or make m_horizontal_offset private, and then add
	the new variable as private too.

	I chose to make m_horizontal_offset private, which is this commit.

	There should be no user visible changes after this commit.

	gdb/tui: disable tui mode when an assert triggers
	When an assert triggers in tui mode the output is not great, the
	internal backtrace that is generated is printed directly to the file
	descriptor for gdb_stderr, and, as a result, does not currently format
	itself correctly - the output uses only '\n' at the end of each line,
	and so, when the terminal is in raw mode, the cursor does not return
	to the start of each line after the '\n'.

	This is mostly fixable, we could update bt-utils.c to use '\r\n'
	instead of just '\n', and this would fix most of the problems.  The
	one we can't easily fix is if/when GDB is built to use execinfo
	instead of libbacktrace, in this case we use backtrace_symbols_fd to
	print the symbols, and this function only uses '\n' as the line
	terminator.  Fixing this would require switching to backtrace_symbols,
	but that API uses malloc, which is something we're trying to
	avoid (this code is called when GDB hits an error, so ideally we don't
	want to rely on malloc).

	However, the execinfo code is only used when libbacktrace is not
	available (or the user specifically disables libbacktrace) so maybe we
	can ignore that problem...

	... but there is another problem.  When the backtrace is printed in
	raw mode, it is possible that the backtrace fills the screen.  With
	the terminal in raw mode we don't have the ability to scroll back,
	which means we loose some of the backtrace, which isn't ideal.

	In this commit I propose that we should disable tui mode whenever we
	handle a fatal signal, or when we hit the internal error code
	path (e.g. when an assert triggers).  With this done then we don't
	need to update the bt-utils.c code, and the execinfo version of the
	code (using backtrace_symbols_fd) works just fine.  We also get the
	ability to scroll back to view the error message and all of the
	backtrace, assuming the users terminal supports scrolling back.

	The only downside I see with this change is if the tui_disable call
	itself causes an error for some reason, or, if we handle a single at a
	time when it is not safe to call tui_disable, in these cases the extra
	tui_disable call might cause GDB to loose the original error.

	However, I think (just from personal experience) that the above two
	issues are pretty rare and the benefits from this change far out
	weighs the possible drawbacks.

2023-01-27  Andrew Burgess  <aburgess@redhat.com>

	gdb/tui: improve errors from tui focus command
	This commit improves (I think) the errors from the tui focus command.
	There are a number of errors that can be triggered by the focus
	command, they include:

	  (1) Window name "NAME" is ambiguous

	  (2) Unrecognized window name "NAME"

	  (3) Window "NAME" cannot be focused

	Error (1) is triggered when the user gives a partial window name, and
	the name matches multiple windows in the current layout.

	It is worth noting that the ambiguity must be within the current
	layout; if the partial name matches one window in the current layout,
	and one or more windows not in the current layout, then this is not
	ambiguous, and focus will shift to the matching window in the current
	layout.

	This error was not previous being tested, but in this commit I make
	use of the Python API to trigger and test this error.

	Error (3) is simple enough, and was already being tested.  This is
	triggered by something like 'focus status'.  The named window needs to
	be present in the current layout, and non-focusable in order to
	trigger the error.

	Error (2) is what I'd like to improve in this commit.  This error
	triggers if the name the user gives doesn't match any window in the
	current layout.  Even if GDB does know about the window, but the
	window isn't in the current layout, then GDB will say it doesn't
	recognize the window name.

	In this commit I propose to to split this error into three different
	errors.  These will be:

	  (a) Unrecognized window name "NAME"

	  (b) No windows matching "NAME" in the current layout

	  (c) Window "NAME" is not in the current layout

	Error (a) is the same as before, but will now only trigger if GDB
	doesn't know about window NAME at all.  If the window is known, but
	not in the current layout then one of the other errors will trigger.

	Error (b) will trigger if NAME is ambiguous for multiple windows that
	are not in the current layout.  If NAME identifies a single window in
	the current layout then that window will continue to be selected, just
	as it currently is.  Only in the case where NAME doesn't identify a
	window in the current layout do we then check all the other known
	windows, if NAME matches multiple of these, then (b) is triggered.

	Finally, error (c) is used when NAME uniquely identifies a single
	window that is not in the current layout.

	The hope with these new errors is that the user will have a better
	understanding of what went wrong.  Instead of GDB claiming to not know
	about a window, the mention of the current layout will hint to the
	user that they should first switch layouts.

	There are tests included for all the new errors.

	In a following commit I managed to trigger the line feed scrolling

	The implementation is pretty simple, just scroll all the content up

	x86: move reg_operands adjustment
	Ideally we'd do away with this somewhat questionable adjustment (leaving
	i.types[] untouched). That's non-trivial though as it looks, so only
	- move the logic into process_operands(), putting it closer to related
	  logic and eliminating a conditional for operand-less insns,
	- make it consistent (i.e. also affect %xmm0), eliminating an ugly
	  special case later in the function.

	x86: drop dead SSE2AVX-related code
	All (there are just two) SSE2AVX templates with %xmm0 as first operand
	also specify VEX3SOURCES. Hence there's no need for an "else" to the
	respective if(), and the if() itself can become an assertion.

	x86: use ModR/M for FPU insns with operands
	This is the correct way of expressing things; encoding the ModR/M byte
	directly in base_opcode has always been bogus.

	x86/Intel: improve special casing of certain insns
	Now that we have identifiers for the mnemonic strings we can avoid
	opcode based comparisons, for (in many cases) being more expensive and
	(in a few cases) being a little fragile and not self-documenting.

	gdb/testsuite/dap: fix gdb.dap/basic-dap.exp disassembly test for PIE
	Prior to this patch, I get:

	    >>> {"seq": 17, "type": "request", "command": "disassemble", "arguments": {"memoryReference": "0x115d", "instructionCount": 1}}
	    Content-Length: 147

	    FAIL: gdb.dap/basic-dap.exp: instructions in disassemble output

	The problem is that the PC to disassemble is taken from the breakpoint
	insertion response, which happens before running.  With a PIE
	executable, that PC is unrelocated, but the disassembly request happens
	after relocation.

	I chose to fix this by watching for a breakpoint changed event giving
	the new breakpoint address, and recording the address from there.  I
	think this is an interesting way to fix it, because it adds a bit of
	test coverage, I don't think these events are checked right now.

	Other ways to fix it would be:

	 - Get the address by doing a breakpoint insertion after the program is
	   started, or some other way.
	 - Do the disassembly by symbol instead of by address.
	 - Do the disassembly before running the program.

	gdb/testsuite/dap: pass around dicts instead of TON objects
	The DAP helper functions generally return TON objects.  However, callers
	almost all immediately use ton::2dict to convert them to dicts, to
	access their contents.  This commits makes things a bit simpler for them
	by having function return dicts directly instead.

	The downside is that the TON objects contain type information.  For
	instance, a "2" in a TCL dict could have been the integer 2 or the
	string "2" in JSON.  By converting to TCL dicts, we lose that
	information.  If some tests specifically want to check the types of some
	fields, I think we can add intermediary functions that return TON
	objects, without having to complicate other callers who don't care.

	[gdb/testsuite] Add gdb.base/unwind-on-each-insn-{amd64,i386}.exp
	The gcc 4.4.x (and earlier) compilers had the problem that the unwind info in
	the epilogue was inaccurate.

	In order to work around this in gdb, epilogue unwinders were added with a
	higher priority than the dwarf unwinders in the amd64 and i386 targets:
	- amd64_epilogue_frame_unwind, and
	- i386_epilogue_frame_unwind.

	Subsequently, the epilogue unwind info problem got fixed in gcc 4.5.0.

	However, the epilogue unwinders prevented gdb from taking advantage of the
	fixed epilogue unwind info, so the scope of the epilogue unwinders was
	limited, bailing out for gcc >= 4.5.0.

	There was no regression test added for this preference scheme, so if we now
	declare epilogue unwind info from all gcc versions as trusted, no test will
	start failing.

	Fix this by adding an amd64 and i386 regression test for this.

	I have no gcc 4.4.x lying around, so I fabricated the assembly files by:
	- commenting out some .cfi directives to break the epilogue unwind info, and
	- hand-editing the producer info to 4.4.7 to activate the fix.

	gdb/arm: Use new dwarf2 function cache
	This patch resolves the performance issue reported in pr/29738 by
	caching the values for the stack pointers for the inner frame.  By
	doing so, the impact can be reduced to checking the state and
	returning the appropriate value.

2023-01-25  Torbjörn SVENSSON  <torbjorn.svensson@foss.st.com>

	gdb: dwarf2 generic implementation for caching function data
	When there is no dwarf2 data for a register, a function can be called
	to provide the value of this register.  In some situations, it might
	not be trivial to determine the value to return and it would cause a
	performance bottleneck to do the computation each time.

	This patch allows the called function to have a "cache" object that it
	can use to store some metadata between calls to reduce the performance
	impact of the complex logic.

	The cache object is unique for each function and frame, so if there are
	more than one function pointer stored in the dwarf2_frame_cache->reg
	array, then the appropriate pointer will be supplied (the type is not
	known by the dwarf2 implementation).

	dwarf2_frame_get_fn_data can be used to retrieve the function unique
	cache object.
	dwarf2_frame_allocate_fn_data can be used to allocate and retrieve the
	function unique cache object.

	[gdb/testsuite] Improve leaf fn in gdb.base/unwind-on-each-insn.exp
	In test-case gdb.base/unwind-on-each-insn.exp, we stepi through function foo
	to check various invariants at each insn, in particular hoping to excercise
	insns that modify stack and frame pointers.

	For x86_64-linux, we have a reasonably complex foo (and similar for -m32):
	...
	  4004bc:       55                      push   %rbp
	  4004bd:       48 89 e5                mov    %rsp,%rbp
	  4004c0:       90                      nop
	  4004c1:       5d                      pop    %rbp
	  4004c2:       c3                      ret
	...
	Both stack pointer (%rsp) and frame pointer (%rbp) are modified.

	Also for s390x-linux (and similar for -m31):
	...
	0000000001000668 <foo>:
	 1000668:       e3 b0 f0 58 00 24       stg     %r11,88(%r15)
	 100066e:       b9 04 00 bf             lgr     %r11,%r15
	 1000672:       e3 b0 b0 58 00 04       lg      %r11,88(%r11)
	 1000678:       07 fe                   br      %r14
	...
	Frame pointer (%r11) is modified.

	Likewise for powerpc64le-linux:
	...
	00000000100006c8 <foo>:
	    100006c8:   f8 ff e1 fb     std     r31,-8(r1)
	    100006cc:   d1 ff 21 f8     stdu    r1,-48(r1)
	    100006d0:   78 0b 3f 7c     mr      r31,r1
	    100006d4:   00 00 00 60     nop
	    100006d8:   30 00 3f 38     addi    r1,r31,48
	    100006dc:   f8 ff e1 eb     ld      r31,-8(r1)
	    100006e0:   20 00 80 4e     blr
	...
	Both stack pointer (r1) and frame pointer (r31) are modified.

	But for aarch64-linux, we have:
	...
	00000000004005fc <foo>:
	  4005fc:       d503201f        nop
	  400600:       d65f03c0        ret
	...
	There's no insn that modifies stack or frame pointer.

	Fix this by making foo more complex, adding an (unused) argument:
	...
	0000000000400604 <foo>:
	  400604:       d10043ff        sub     sp, sp, #0x10
	  400608:       f90007e0        str     x0, [sp, #8]
	  40060c:       d503201f        nop
	  400610:       910043ff        add     sp, sp, #0x10
	  400614:       d65f03c0        ret
	...
	such that the stack pointer (sp) is modified.

	[ Note btw that we're seeing the effects of -momit-leaf-frame-pointer, with
	-mno-omit-leaf-frame-pointer we have instead:
	...
	0000000000400604 <foo>:
	  400604:       a9be7bfd        stp     x29, x30, [sp, #-32]!
	  400608:       910003fd        mov     x29, sp
	  40060c:       f9000fa0        str     x0, [x29, #24]
	  400610:       d503201f        nop
	  400614:       a8c27bfd        ldp     x29, x30, [sp], #32
	  400618:       d65f03c0        ret
	...
	such that also the frame pointer (x29) is modified. ]

	Having made foo more complex, we now run into the following fail on
	x86_64/-m32:
	...
	FAIL: gdb.base/unwind-on-each-insn.exp: instruction 1: $sp_value == $main_sp
	....

	The problem is that the stack pointer has changed inbetween the sampling of
	main_sp and *foo, in particular by the push insn:
	...
	 804841a:       68 c0 84 04 08          push   $0x80484c0
	 804841f:       e8 10 00 00 00          call   8048434 <foo>
	...

	Fix this by updating main_sp.

	On powerpc64le-linux, with gcc 7.5.0 I now run into PR tdep/30021:
	...
	FAIL: gdb.base/unwind-on-each-insn.exp: insn 7: $fba_value == $main_fba
	FAIL: gdb.base/unwind-on-each-insn.exp: insn 7: [string equal $fid $main_fid]
	...
	but I saw the same failure before this commit with gcc 4.8.5.

	Tested on:
	- x86_64-linux (-m64 and -m32)
	- s390x-linux (-m64 and -m31)
	- powerpc64le-linux
	- aarch64-linux

	Also I've checked that the test-case still functions as regression test for PR
	record/16678 on x86_64.

	gdb/tui: make use of a scoped_restore
	Make use of a scoped_restore object in tui_mld_read_key instead of
	doing a manual save/restore.

	I don't think the existing code can throw an exception, so this is
	just a cleanup rather than a bug fix.

	There should be no user visible changes after this commit.

	gdb/tui: better filtering of tab completion results for focus command
	While working on the previous couple of commits, I noticed that the
	'focus' command would happily suggest 'status' as a possible focus
	completion, even though the 'status' window is non-focusable, and,
	after the previous couple of commits, trying to focus the status
	window will result in an error.

	This commit improves the tab-completion results for the focus command
	so that the status window is not included.

	gdb/tui: convert if/error to an assert
	While working on the previous commit, I realised that there was an
	error in tui_set_focus_command that could never be triggered.

	Since the big tui rewrite (adding dynamic layouts) it is no longer
	true that there is a tui_win_info object for every window at all
	times.  We now only create a tui_win_info object for a particular
	window, when the window is part of the current layout.  As a result,
	if we have a tui_win_info pointer, then the window must be visible
	inside tui_set_focus_command (this function calls tui_enable as its
	first action, which makes the current layout visible).

	The gdb.tui/tui-focus.exp test script exercises this area of code, and
	doesn't trigger the assert, nor do any of our other existing tui
	tests.

	gdb/testsuite/tui: more testing of the 'focus' command
	I noticed that we didn't have many tests of the tui 'focus' command,
	so I started adding some.  This exposed a bug in GDB; we are able to
	focus windows that should not be focusable, e.g. the 'status' window.

	This is harmless until we then do 'focus next' or 'focus prev', along
	this code path we assert that the currently focused window is
	focusable, which obviously, is not always true, so GDB fails with an
	assertion error.

	The fix is simple; add a check to the tui_set_focus_command function
	to ensure that the selected window is focusable.  If it is not then an
	error is thrown.  The new tests I've added cover this case.

	gdb/testsuite: update gdb.tui/tui-nl-filtered-output.exp
	Following on from the previous commit, in this commit I am updating
	the test script gdb.tui/tui-nl-filtered-output.exp to take account of
	the changes in commit:

	  commit 9162a27c5f5828240b53379d735679e2a69a9f41
	  Date:   Tue Nov 13 11:59:03 2018 -0700

	      Change gdb test suite's TERM setting

	In the above commit the TERM environment variable was changed to be
	'dumb' by default, which means that tests, that previously activated
	tui mode, no longer do unless TERM is set to 'ansi'.

	As the gdb.tui/tui-nl-filtered-output.exp script didn't do this, the
	test stopped working.  As the expect patterns in this script were
	pretty generic no tests actually started failing, and we never
	noticed.

	In this commit I update the test script to correctly activate our
	terminal emulator, the test continues to pass after this update, but
	now we are testing in tui mode.

	gdb/testsuite: update gdb.tui/tui-disasm-long-lines.exp
	Following on from the previous commit, in this commit I am updating
	the test script gdb.tui/tui-disasm-long-lines.exp to take account of
	the changes in commit:

	  commit 9162a27c5f5828240b53379d735679e2a69a9f41
	  Date:   Tue Nov 13 11:59:03 2018 -0700

	      Change gdb test suite's TERM setting

	In the above commit the TERM environment variable was changed to be
	'dumb' by default, which means that tests, that previously activated
	tui mode, no longer do unless TERM is set to 'ansi'.

	As the gdb.tui/tui-disasm-long-lines.exp script didn't do this, the
	test stopped working.  As the expect patterns in this script were
	pretty generic no tests actually started failing, and we never
	noticed.

	In this commit I update the script to use Term::clean_restart, which
	correctly sets TERM to 'ansi'.  I've also added a check that the asm
	box does appear on the screen, which should indicate that tui mode has
	correctly activated.

	However, I also notice that GDB doesn't appear to fully work
	correctly.  The test should display the disassembly for the test
	program, but it doesn't.

	The test is trying to disassemble some code that (deliberately) uses a
	very long symbol name, this eventually results in GDB entering
	tui_source_window_base::show_source_content and trying to allocate an
	ncurses pad in order to hold the current page of disassembler output.

	Unfortunately, due to the very long line, the call to newpad fails,
	meaning that tui_source_window_base::m_pad is nullptr.  Luckily non of
	the following calls appear to crash when passed a nullptr, however,
	all the output that is written to the pad is lost, which is why we
	don't see any assembly code written to the screen.

	As the test history indicates that the script was originally checking
	for a crash in GDB when the long identifier was encountered, I think
	there is value in just leaving the test as it is for now, I have a fix
	for the issue of the newpad call failing, which I'll post in a follow
	up commit later.

	gdb/testsuite: extend gdb.tui/tui-layout.exp test script
	In passing I noticed that the gdb.tui/tui-layout.exp test script was a
	little strange, it tests the layout command multiple times, but never
	sets up our ANSI terminal emulator, so every layout command fails with
	a message about the terminal lacking the required abilities.

	It turns out that this was caused by this commit:

	  commit 9162a27c5f5828240b53379d735679e2a69a9f41
	  Date:   Tue Nov 13 11:59:03 2018 -0700

	      Change gdb test suite's TERM setting

	This was when we changed the testsuite to set the TERM environment
	variable to "dumb" by default.

	After this, any tui test that didn't set the terminal mode back to
	'ansi' would fail to activate tui mode.

	For the tui-layout.exp test it just so happens that the test patterns
	are generic enough that the test continued to pass, even after this
	change.

	In this commit I have updated the test so we now check the layout
	command both with a 'dumb' terminal and with the 'ansi' terminal.
	When testing with the 'ansi' terminal, I have some limited validation
	that GDB correctly entered tui mode.

	I figured that it is probably worth having at least one test in the
	test suite that deliberately tries to enter tui mode in a dumb
	terminal, it would be sad if we one day managed to break GDB such that
	this caused a crash, and never noticed.

	gdb/testsuite: rename test source file to match test script
	The previous commit touched the source file for the test script
	gdb.cp/cpcompletion.exp.  This source file is called pr9594.cc.  The
	source file is only used by the one test script.

	This commit renames the source file to cpcompletion.cc to match the

	[gdb/tdep, aarch64] Fix frame address of last insn
	Consider the test-case test.c, compiled without debug info:

	int
	main (void)
	{
	  foo ("foo");
	  return 0;

	...

	Disassembly of foo:
	...
	0000000000400564 <foo>:
	  400564:       d10043ff        sub     sp, sp, #0x10
	  400568:       f90007e0        str     x0, [sp, #8]

	Now, let's do "info frame" at each insn in foo, as well as printing $sp

	The frame address is calculated here in aarch64_make_prologue_cache_1:

	  unwound_fp = get_frame_register_unsigned (this_frame, cache->framereg);
	  if (unwound_fp == 0)
	    return;

	  cache->prev_sp = unwound_fp + cache->framesize;
	...

	For insns after the prologue, we have cache->framereg == sp and
	cache->framesize == 16, so unwound_fp + cache->framesize gives the wrong
	answer once sp has been restored to entry value by the before-last insn.

	Fix this by detecting the situation that the sp has been restored.

	This fixes PRs tdep/30010 and tdep/30011.

	This also fixes the aarch64 FAILs in gdb.reverse/solib-precsave.exp and

	[gdb/testsuite] Avoid using .eh_frame in gdb.base/unwind-on-each-insn.exp
	One purpose of the gdb.base/unwind-on-each-insn.exp test-case is to test the
	architecture-specific unwinders on foo, so unwind-on-each-insn-foo.c is
	compiled with nodebug, to prevent the dwarf unwinders from taking effect.

	For for instance gcc x86_64 though, -fasynchronous-unwind-tables is enabled by
	default, generating an .eh_frame section contribution which might enable the
	dwarf unwinders and bypass the architecture-specific unwinders.

	Currently, that happens to be not the case due to the current implementation
	of epilogue_unwind_valid, which assumes that in absence of debug info proving
	that the compiler is gcc >= 4.5.0, the .eh_frame contribution is invalid.

	That may change though, see PR30028, in which case
	gdb.base/unwind-on-each-insn.exp stops being a regression test for commit
	49d7cd733a7 ("Change calculation of frame_id by amd64 epilogue unwinder").

	Fix this by making sure that we don't use .eh_frame info regardless of
	epilogue_unwind_valid, simply by not generating it using
	-fno-asynchronous-unwind-tables.

	Tested on x86_64-linux, target boards unix/{-m64,-m32}, using compilers
	gcc 7.5.0 and clang 13.0.1.

	[gdb/testsuite] Simplify gdb.base/unwind-on-each-insn.exp
	In test-case gdb.base/unwind-on-each-insn.exp, we try to determine the last
	disassembled insn in function foo.

	This in it self is fragile, as demonstrated by commit 91836f41e20 ("Powerpc
	fix for gdb.base/unwind-on-each-insn.exp").

	The use of the last disassembled insn in the test-case is to stop stepping in
	foo once reaching it.

	However, the intent is to stop stepping just before returning to main.

	There is no guarantee that the last disassembled insn:
	- is actually executed
	- is executed just before returning to main
	- is executed only once.

	Fix this by simplying the test-case to continue stepping till stepping out of
	foo.

	Tested on x86_64-linux.

	gdb: make user-created frames reinflatable
	This patch teaches frame_info_ptr to reinflate user-created frames
	(frames created through create_new_frame, with the "select-frame view"
	command).

	Before this patch, frame_info_ptr doesn't support reinflating
	user-created frames, because it currently reinflates by getting the
	current target frame (for frame 0) or frame_find_by_id (for other
	frames).  To reinflate a user-created frame, we need to call
	create_new_frame, to make it lookup an existing user-created frame, or
	otherwise create one.

	So, in prepare_reinflate, get the frame id even if the frame has level
	0, if it is user-created.  In reinflate, if the saved frame id is user
	create it, call create_new_frame.

	In order to test this, I initially enhanced the gdb.base/frame-view.exp
	test added by the previous patch by setting a pretty-printer for the
	type of the function parameters, in which we do an inferior call.  This
	causes print_frame_args to not reinflate its frame (which is a
	user-created one) properly.  On one machine (my Arch Linux one), it
	properly catches the bug, as the frame is not correctly restored after
	printing the first parameter, so it messes up the second parameter:

	    frame
	    #0  baz (z1=hahaha, z2=<error reading variable: frame address is not available.>) at /home/simark/src/binutils-gdb/gdb/testsuite/gdb.base/frame-view.c:40
	    40        return z1.m + z2.n;

	    40        return z1.m + z2.n;
	    (gdb) FAIL: gdb.base/frame-view.exp: with_pretty_printer=true: frame again

	However, on another machine (my Ubuntu 22.04 one), it just passes fine,
	without the appropriate fix.  I then thought about writing a selftest
	for that, it's more reliable.  I left the gdb.base/frame-view.exp pretty
	printer test there, it's already written, and we never know, it might
	catch some unrelated issue some day.

	gdb: make it possible to restore selected user-created frames
	I would like to improve frame_info_ptr to automatically grab the
	information needed to reinflate a frame, and automatically reinflate it
	as needed.  One thing that is in the way is the fact that some frames
	can be created out of thin air by the create_new_frame function.  These
	frames are not the fruit of unwinding from the target's current frame.
	These frames are created by the "select-frame view" command.

	These frames are not correctly handled by the frame save/restore
	functions, save_selected_frame, restore_selected_frame and
	lookup_selected_frame.  This can be observed here, using the test
	included in this patch:

	Here, we create a custom frame for thread 1 (using the stack from thread
	2, for convenience):

	    (gdb) select-frame view 0x7ffff7cc3f80 0x5555555551a2

	The first calls to "frame" looks good:

	    (gdb) frame
	    #0  thread_func (p=0x7ffff7d4e630) at /home/simark/src/binutils-gdb/gdb/testsuite/gdb.base/frame-view.c:42
	    42        foo (11);

	But not the second one:

	    (gdb) frame
	    #0  0x00007ffff7d4b4b6 in ?? () from /usr/lib/libc.so.6

	This second "frame" command shows the current target frame instead of
	the user-created frame.

	It's not totally clear how the "select-frame view" feature is expected
	to behave, especially since it's not tested.  I heard accounts that it
	used to be possible to select a frame like this and do "up" and "down"
	to navigate the backtrace starting from that frame.  The fact that
	create_new_frame calls frame_unwind_find_by_frame to install the right
	unwinder suggest that it used to be possible.  But that doesn't work
	today:

	    (gdb) select-frame view 0x7ffff7cc3f80 0x5555555551a2
	    (gdb) up
	    Initial frame selected; you cannot go up.
	    (gdb) down
	    Bottom (innermost) frame selected; you cannot go down.

	and "backtrace" always shows the actual thread's backtrace, it ignores
	the user-created frame:

	    (gdb) bt
	    #0  0x00007ffff7d4b4b6 in ?? () from /usr/lib/libc.so.6
	    #1  0x00007ffff7d50403 in ?? () from /usr/lib/libc.so.6
	    #2  0x000055555555521a in main () at /home/simark/src/binutils-gdb/gdb/testsuite/gdb.base/frame-view.c:56

	I don't want to address all the `select-frame view` issues , but I think
	we can agree that the "frame" command changing the selected frame, as
	shown above, is a bug.  I would expect that command to show the
	currently selected frame and not change it.

	This happens because of the scoped_restore_selected_frame object in
	print_frame_args.  The frame information is saved in the constructor
	(the backtrace below), and restored in the destructor.

	Since the user-created frame has level 0 (identified by the saved level
	-1), lookup_selected_frame just reselects the target's current frame,
	and the user-created frame is lost.

	My goal here is to fix this particular problem.

	Currently, select_frame does not set selected_frame_id and
	selected_frame_level for frames with level 0.  It leaves them at
	null_frame_id / -1, indicating to restore_selected_frame to use the
	target's current frame.  User-created frames also have level 0, so add a
	special case them such that select_frame saves their selected id and
	level.

	save_selected_frame does not need any change.

	Change the assertion in restore_selected_frame that checks `frame_level
	!= 0` to account for the fact that we can restore user-created frames,
	which have level 0.

	Finally, change lookup_selected_frame to make it able to re-create
	user-created frame_info objects from selected_frame_level and
	selected_frame_id.

	Add a minimal test case for the case described above, that is the
	"select-frame view" command followed by the "frame" command twice.  In
	order to have a known stack frame to switch to, the test spawns a second
	thread, and tells the first thread to use the other thread's top frame.

	gdb: add user-created frames to stash
	A subsequent patch makes it possible for frame_info_ptr to reinflate
	user-created frames.  If two frame_info_ptr objects wrapping the same
	user-created frame_info need to do reinflation, we want them to end up
	pointing to the same frame_info instance, and not create two separate
	frame_infos.  Otherwise, GDB gets confused down the line, as the state
	kept in one frame_info object starts differing from the other
	frame_info.

	Achieve this by making create_new_frame place the user-created frames in
	the frame stash.  This way, when the second frame_info_ptr does
	reinflation, it will find the existing frame_info object, created by the
	other frame_info_ptr, in the frame stash.

	To make the frame stash differentiate between regular and user-created
	frame infos which would otherwise be equal, change frame_addr_hash and
	frame_id::operator== to account for frame_id::user_created_p.

	I made create_new_frame look up existing frames in the stash, and only
	create one if it doesn't find one.  The goal is to avoid the
	"select-frame view"/"info frame view"/"frame view" commands from
	overriding existing entries into the stash, should the user specify the
	same frame more than once.  This will also help in the subsequent patch
	that makes frame_info_ptr capable of reinflating user-created frames.
	It will be able to just call create_new_frame and it will do the right
	thing.

	When running gdb.ada/arrayptr.exp (and others) on Ubuntu 22.04, with the

	      low.set_const_val (low.const_val () | negative_mask);

	When the base type's length (16 bytes in this case) is larger than a
	ULONGEST (typically 8 bytes), the bit shift is too large.

	My obvious fix is just to skip the fixup for base types larger than a
	ULONGEST (8 bytes).  I don't think we really handle constant attribute
	values larger than 8 bytes anyway, so this is part of a much larger
	problem.

	Add a test that replicates this situation, but uses bounds that fit in a
	signed 64 bit, so we get a sensible result.

	gdb/testsuite: add test for negative subrange bounds with unsigned form
	I am looking at this code [1]:

	  /* Normally, the DWARF producers are expected to use a signed
	     constant form (Eg. DW_FORM_sdata) to express negative bounds.
	     But this is unfortunately not always the case, as witnessed
	     with GCC, for instance, where the ambiguous DW_FORM_dataN form
	     is used instead.  To work around that ambiguity, we treat
	     the bounds as signed, and thus sign-extend their values, when
	     the base type is signed.  */
	  negative_mask =
	    -((ULONGEST) 1 << (base_type->length () * TARGET_CHAR_BIT - 1));
	  if (low.kind () == PROP_CONST
	      && !base_type->is_unsigned () && (low.const_val () & negative_mask))
	    low.set_const_val (low.const_val () | negative_mask);
	  if (high.kind () == PROP_CONST
	      && !base_type->is_unsigned () && (high.const_val () & negative_mask))
	    high.set_const_val (high.const_val () | negative_mask);

	Nothing in the testsuite seems to exercise it, as when I remove it, all
	of gdb.dwarf2 still passes.  And tests in other directories would be
	compiler-dependent, so would rely on having a buggy compiler.

	Update gdb.dwarf2/subrange.exp to have a test for it.  When removing the
	code above, the new test fails with:

	  ptype array_with_buggy_negative_bounds_type^M
	  type = array [240..244] of signed_byte^M
	  (gdb) FAIL: gdb.dwarf2/subrange.exp: ptype array_with_buggy_negative_bounds_type

	instead of the expected:

	  ptype array_with_buggy_negative_bounds_type^M
	  type = array [-16..-12] of signed_byte^M
	  (gdb) PASS: gdb.dwarf2/subrange.exp: ptype array_with_buggy_negative_bounds_type

	makes it so that also the partially merged sections are conceptually
	SEC_EXCLUDED, except the first merge section (e.g. as if the very
	first object file already contains all strings).  So that second mapping
	symbol is now missing.  It never was needed anyway.

	So, adjust the test.

	Faster string merging
	* use power-of-two hash table
	* use better hash function (hashing 32bits at once and with better
	  mixing characteristics)
	* use input-offset-to-entry maps instead of retaining full input
	  contents for lookup time
	* don't reread SEC_MERGE section multiple times
	* care for cache behaviour for the hot lookup routine

	The overall effect is less usage in libz and much faster string merging
	itself.  On a debug-info-enabled cc1 the effect at the time of this
	writing on the machine I used was going from 14400 perf samples to 9300
	perf samples or from 3.7 seconds to 2.4 seconds, i.e. about 33% .

	bytes long. Otoh no register name is longer than 8 bytes. Hence even for
	32-bit builds using a pointer is only slightly more space efficient than
	embedding the strings. A level of indirection can be also avoided by
	embedding the names as an array of 8 characters directly in the arrays,
	and the number of base relocations in libopcodes.so (or PIE builds of
	statically linked executables) goes down as well.

	To amortize for the otherwise reduced folding of string literals by the
	linker, use att_names_seg[] in place of string literals in append_seg()
	and OP_ESreg().

	x86: embed register names in reg_entry
	Register names are (including their nul terminators) on average almost 4
	bytes long. Otoh no register name is longer than 7 bytes. Hence even for
	32-bit builds using a pointer is only slightly more space efficient than
	embedding the strings. A level of indirection can be also avoided by
	embedding the names as an array of 8 characters directly in the struct,
	and the number of base relocations in PIE builds of gas goes down as
	well.

	x86: avoid strcmp() in a few places
	Now that we have identifiers for the mnemonic strings we can avoid
	strcmp() in a number of places, comparing the offsets into the mnemonic
	string table instead. While doing this also
	- convert a leftover strncmp() to startswith() (apparently an oversight
	  when rebasing the original patch introducing the startswith() uses),
	- use the new shorthand for current_templates->start also elsewhere in
	  md_assemble() (valid up to the point where match_template() is
	  called).

	x86: absorb allocation in i386-gen
	When generating the mnemonic string table we already set up an
	identifier for the following entry in a number of cases. Re-use that on
	the next loop iteration rather than re-doing allocation and conversion.

	x86: re-use insn mnemonic strings as much as possible
	Compact the mnemonic string table such that the tails of longer
	mnemonics are re-used for shorter ones, going beyond what compilers
	would typically do, but matching what ELF linkers may do when processing
	SHF_MERGE|SHF_STRINGS sections. This reduces table size by about 12.5%.

2023-01-20  Jan Beulich  <jbeulich@suse.com>

	x86: move insn mnemonics to a separate table
	Using full pointers to reference the insn mnemonic strings is not very
	efficient. With overall string size presently just slightly over 20k,
	even a 16-bit value would suffice. Use "unsigned int" for now, as
	there's no good use we could presently make of the otherwise saved 16
	bits.

	For 64-bit builds this reduces table size by 6.25% (prior to the recent
	ISA extension additions it would have been 12.5%), with a similar effect
	on cache occupation of table entries accessed. For PIE builds of gas
	this also reduces the number of base relocations quite a bit (obviously
	independent of bitness).

	GDB/testsuite: Expand for character string limiting options
	Modify test cases that verify the operation of the array element limit
	with character strings such that they are executed twice, once with the
	`set print characters' option set to `elements' and the limit controlled
	with the `set print elements' option, and then again with the limit
	controlled with the `set print characters' option instead.  Similarly
	with the `-elements' and `-characters' options for the `print' command.
	Additionally verify that said `print' command options combined yield the
	expected result.

	Verify correct $_gdb_setting and $_gdb_setting_str values for the `print
	characters' setting, in particular the `void' value for the `elements'
	default, which has no corresponding integer value exposed.

	Add Guile and Python coverage for the `print characters' GDB setting.

	There are new tests for Ada and Pascal, as the string printing code for
	these languages is different than the generic string printing code used
	by other languages.  Modula2 also has different string printing code,
	but (a) this is similar to Pascal, and (b) there are no existing modula2
	tests written in Modula2, so I'm not sure how I'd even test the Modula2
	string printing.

	GDB: Add a character string limiting option
	This commit splits the `set/show print elements' option into two.  We
	retain `set/show print elements' for controlling how many elements of an
	array we print, but a new `set/show print characters' setting is added
	which is used for controlling how many characters of a string are
	printed.

	The motivation behind this change is to allow users a finer level of
	control over how data is printed, reflecting that, although strings can
	be thought of as arrays of characters, users often want to treat these
	two things differently.

	For compatibility reasons by default the `set/show print characters'
	option is set to `elements', which makes the limit for character strings
	follow the setting of the `set/show print elements' option, as it used
	to.  Using `set print characters' with any other value makes the limit
	independent from the `set/show print elements' setting, however it can
	be restored to the default with the `set print characters elements'
	command at any time.

	A corresponding `-characters' option for the `print' command is added,
	with the same semantics, i.e. one can use `elements' to make a given
	`print' invocation follow the limit of elements, be it set with the
	`-elements' option also given with the same invocation or taken from the
	`set/show print elements' setting, for characters as well regardless of
	the current setting of the `set/show print characters' option.

	The GDB changes are all pretty straightforward, just changing references
	to the old 'print_max' to use a new `get_print_max_chars' helper which
	figures out which of the two of `print_max' and `print_max_chars' values
	to use.

	Likewise, the documentation is just updated to reference the new setting
	where appropriate.

	To make people's life easier the message shown by `show print elements'
	now indicates if the setting also applies to character strings:

	(gdb) set print characters elements
	(gdb) show print elements
	Limit on string chars or array elements to print is 200.
	(gdb) set print characters unlimited
	(gdb) show print elements
	Limit on array elements to print is 200.
	(gdb)

	and the help text shows the dependency as well:

	(gdb) help set print elements
	Set limit on array elements to print.
	"unlimited" causes there to be no limit.
	This setting also applies to string chars when "print characters"
	is set to "elements".
	(gdb)

	In the testsuite there are two minor updates, one to add `-characters'
	to the list of completions now shown for the `print' command, and a bare
	minimum pair of checks for the right handling of `set print characters'
	and `show print characters', copied from the corresponding checks for
	`set print elements' and `show print elements' respectively.

	GDB: Allow arbitrary keywords in integer set commands
	Rather than just `unlimited' allow the integer set commands (or command
	options) to define arbitrary keywords for the user to use, removing
	hardcoded arrangements for the `unlimited' keyword.

	Remove the confusingly named `var_zinteger', `var_zuinteger' and
	`var_zuinteger_unlimited' `set'/`show' command variable types redefining
	them in terms of `var_uinteger', `var_integer' and `var_pinteger', which
	have the range of [0;UINT_MAX], [INT_MIN;INT_MAX], and [0;INT_MAX] each.

	Following existing practice `var_pinteger' allows extra negative values
	to be used, however unlike `var_zuinteger_unlimited' any number of such
	values can be defined rather than just `-1'.

	The "p" in `var_pinteger' stands for "positive", for the lack of a more
	appropriate unambiguous letter, even though 0 obviously is not positive;
	"n" would be confusing as to whether it stands for "non-negative" or
	"negative".

	Add a new structure, `literal_def', the entries of which define extra
	keywords allowed for a command and numerical values they correspond to.
	Those values are not verified against the basic range supported by the
	underlying variable type, allowing extra values to be allowed outside
	that range, which may or may not be individually made visible to the
	user.  An optional value translation is possible with the structure to
	follow the existing practice for some commands where user-entered 0 is
	internally translated to UINT_MAX or INT_MAX.  Such translation can now
	be arbitrary.  Literals defined by this structure are automatically used
	for completion as necessary.

	So for example:

	const literal_def integer_unlimited_literals[] =
	  {
	    { "unlimited", INT_MAX, 0 },
	    { nullptr }
	  };

	defines an extra `unlimited' keyword and a user-visible 0 value, both of
	which get translated to INT_MAX for the setting to be used with.

	Similarly:

	const literal_def zuinteger_unlimited_literals[] =
	  {
	    { "unlimited", -1, -1 },
	    { nullptr }
	  };

	defines the same keyword and a corresponding user-visible -1 value that
	is used for the requested setting.  If the last member were omitted (or
	set to `{}') here, then only the keyword would be allowed for the user
	to enter and while -1 would still be used internally trying to enter it
	as a part of a command would result in an "integer -1 out of range"
	error.

	Use said error message in all cases (citing the invalid value requested)
	replacing "only -1 is allowed to set as unlimited" previously used for
	`var_zuinteger_unlimited' settings only rather than propagating it to
	`var_pinteger' type.  It could only be used for the specific case where
	a single extra `unlimited' keyword was defined standing for -1 and the
	use of numeric equivalents is discouraged anyway as it is for historical
	reasons only that they expose GDB internals, confusingly different
	across variable types.  Similarly update the "must be >= -1" Guile error
	message.

	Redefine Guile and Python parameter types in terms of the new variable
	types and interpret extra keywords as Scheme keywords and Python strings
	used to communicate corresponding parameter values.  Do not add a new
	PARAM_INTEGER Guile parameter type, however do handle the `var_integer'
	variable type now, permitting existing parameters defined by GDB proper,
	such as `listsize', to be accessed from Scheme code.

	With these changes in place it should be trivial for a Scheme or Python
	programmer to expand the syntax of the `make-parameter' command and the
	`gdb.Parameter' class initializer to have arbitrary extra literals along
	with their internal representation supplied.

	Update the testsuite accordingly.

	PowerPC: fix for gdb.reverse/finish-precsave.exp and gdb.reverse/finish-reverse.exp
	PR record/29927 - reverse-finish requires two reverse next instructions to
	reach previous source line

	PowerPC uses two entry points called the local entry point (LEP) and the
	global entry point (GEP).  Normally the LEP is used when calling a
	function.  However, if the table of contents (TOC) value in register 2 is
	not valid the GEP is called to setup the TOC before execution continues at
	the LEP.  When executing in reverse, the function finish_backward sets the
	break point at the alternate entry point (GEP).  However if the forward
	execution enters via the normal entry point (LEP), the reverse execution
	never sees the break point at the GEP of the function.  Reverse execution
	continues until the next break point is encountered or the end of the
	recorded log is reached causing gdb to stop at the wrong place.

	This patch adds a new address to struct execution_control_state to hold the
	address of the alternate function start address, known as the GEP on
	PowerPC.  The finish_backwards function is updated.  If the stopping point
	is between the two entry points (the LEP and GEP on PowerPC), the stepping
	range is set to execute back to the alternate entry point (GEP on PowerPC).
	Otherwise, a breakpoint is inserted at the normal entry point (LEP on
	PowerPC).

	Function process_event_stop_test checks uses a stepping range to stop
	execution in the caller at the first instruction of the source code line.
	Note, on systems that only support one entry point, the address of the two
	entry points are the same.

	Test finish-reverse-next.exp is updated to include tests for the
	reverse-finish command when the function is entered via the normal entry
	point (i.e. the LEP) and the alternate entry point (i.e. the GEP).

	The patch has been tested on X86 and PowerPC with no regressions.

2023-01-17  Carl Love  <cel@us.ibm.com>

	X86: reverse-finish fix
	PR record/29927  - reverse-finish requires two reverse next instructions to
	reach previous source line

	Currently on X86, when executing the finish command in reverse, gdb does a
	single step from the first instruction in the callee to get back to the
	caller.  GDB stops on the last instruction in the source code line where
	the call was made.  When stopped at the last instruction of the source code
	line, a reverse next or step command will stop at the first instruction
	of the same source code line thus requiring two step/next commands to
	reach the previous source code line.  It should only require one step/next
	command to reach the previous source code line.

	By contrast, a reverse next or step command from the first line in a
	function stops at the first instruction in the source code line where the
	call was made.

	This patch fixes the reverse finish command so it will stop at the first
	instruction of the source line where the function call was made.  The
	behavior on X86 for the reverse-finish command now matches doing a
	reverse-next from the beginning of the function.

	The proceed_to_finish flag in struct thread_control_state is no longer
	used.  This patch removes the declaration, initialization and setting of
	the flag.

	This patch requires a number of regression tests to be updated.  Test
	gdb.mi/mi-reverse.exp no longer needs to execute two steps to get to the
	previous line.  The gdb output for tests gdb.reverse/until-precsave.exp
	and gdb.reverse/until-reverse.exp changed slightly.  The expected result in
	tests gdb.reverse/amd64-failcall-reverse.exp and
	gdb.reverse/singlejmp-reverse.exp are updated to the correct expected
	result.

	This patch adds a new test gdb.reverse/finish-reverse-next.exp to test the
	reverse-finish command when returning from the entry point and from the
	body of the function.

	The step_until proceedure in test gdb.reverse/step-indirect-call-thunk.exp
	was moved to lib/gdb.exp and renamed cmd_until.

	The patch has been tested on X86 and PowerPC to verify no additional
	regression failures occured.

	gdb/testsuite: expect SIGSEGV from top GDB spawn id

	This is because the -re that is supposed to match this SIGSEGV is after
	`-i $inferior_spawn_id`.  On native, the top and bottom GDB are on the
	same spawn id, so it ends up working.  But with a gdbserver board,
	that's not the case.  Move the SIGSEGV -re before the `-i

	Do the same fix in gdb.gdb/python-helper.exp.

	Move hash_entry and eq_entry into cooked_index::do_finalize
	I was briefly confused by the hash_entry and eq_entry functions in the

	table.  So, it seemed cleaner to move these there as well.

	Don't erase empty indices in DWARF reader
	The DWARF reader has some code to remove empty indices.  However, I
	think this code has been obsolete since some earlier changes to
	parallel_for_each.  This patch removes this code.

	Avoid submitting empty tasks in parallel_for_each
	I found that parallel_for_each would submit empty tasks to the thread
	pool.  For example, this can happen if the number of tasks is smaller
	than the number of available threads.  In the DWARF reader, this
	resulted in the cooked index containing empty sub-indices.  This patch
	arranges to instead shrink the result vector and process the trailing
	entries in the calling thread.

	gas: arm: Change warning message to not reference specific A-class architecture revision
	We noticed that a warning message about the use of scalar fp16
	instructions being UNPREDICTABLE when conditionalized in an IT
	block referenced the specific A-class architecture revision
	ARMv8.2-A.
	Many of these instructions are now also part of ARMv8.1-M, so
	the warning message had become misleading.  Here we just change
	the message to not specify an architecture revision at all and
	update all testing accordingly.  This was done with a simple
	find-n-replace within the binutils sources.  No tests have
	regressed for the arm target.

	gas: arm: Fix a further IT-predicated vcvt issue in the presense of MVE vcvtn
	Previously we had experienced issues with assembling a "VCVTNE" instruction
	in the presence of the MVE architecture extension, because it could be
	interpreted both as:

	* The base instruction VCVT + NE for IT predication when inside an IT block.
	* The MVE instruction VCVTN + E in the Else of a VPT block.

	Given a C reproducer of:
	```
	int test_function(float value)
	{
	  int ret_val = 10;
	  if (value != 0.0)
	  {
	    ret_val = (int) value;
	  }
	  return ret_val;
	}
	```
	GCC generates a VCVTNE instruction based on the `truncsisf2_vfp`
	pattern, which will look like:
	`vcvtne.s32.f32 s-reg, s-reg`
	This still triggers an error due to being misidentified as "vcvtn+e"
	Similar errors were found with other type combinations and instruction
	patterns (these have all been added to the testing of this patch).

	This class of errors was previously worked around by:
	https://sourceware.org/pipermail/binutils/2020-August/112728.html
	which addressed this by looking at the operand types, however,
	that isn't adequate to cover all the extra cases that have been
	found.  Instead, we add some special-casing logic earlier when
	the instructions are parsed that is conditional on whether we are
	in a VPT block or not, when the instruction is parsed.

	libctf: update regexp to allow makeinfo to build document
	While trying to build gdb on latest openSUSE Tumbleweed, I noticed the
	following warning,

	 checking for makeinfo... makeinfo --split-size=5000000
	 configure: WARNING:
	 *** Makeinfo is too old. Info documentation will not be built.

	then I checked the version of makeinfo, it said,

	$ makeinfo --version
	texi2any (GNU texinfo) 7.0.1

	======

	After digging a little bit, it became quite obvious that a dot is
	missing in regexp that makes it impossible to match versions higher than
	7.0, and here's the solution:

	-       | egrep 'texinfo[^0-9]*(6\.[3-9]|[7-9][0-9])' >/dev/null 2>&1; then
	+       | egrep 'texinfo[^0-9]*(6\.[3-9]|[7-9]\.[0-9])' >/dev/null 2>&1; then

	However, Eli pointed out that the solution above has another problem: it
	will stop working when Texinfo 10.1 will be released.  Meanwhile, he
	suggested to solve this problem permanently.  That is, we don't care
	about the minor version for Texinfo > 6.9, we only care about the major
	version.

	In this way, the problem will be resolved permanently, thanks to Eli.

	sim: assume sys/stat.h always exists (via gnulib)
	We have many uses of sys/stat.h that are unprotected by HAVE_SYS_STAT_H,
	so this is more formalizing the reality that we require this header.
	Since we switched to gnulib, it guarantees that a sys/stat.h exists
	for us to include, so we're doubly OK.

	sim: formally assume unistd.h always exists (via gnulib)
	We have many uses of unistd.h that are unprotected by HAVE_UNISTD_H,
	so this is more formalizing the reality that we require this header.
	Since we switched to gnulib, it guarantees that a unistd.h exists
	for us to include, so we're doubly OK.

	sim: build: stop probing system extensions (ourselves)
	This logic was added in order to expose the strsignal prototype for
	nrun.c.  Since then, we've migrated to gnulib as our portability layer,
	and it takes care of probing system extensions for us, so there's no
	need to duplicate the work.

	sim: modules.c: fix generation after recent refactors
	Add explicit arch-specific modules.c rules to keep the build from
	generating an incorrect common/modules.c.  Otherwise the pattern
	rules would cascade such that it'd look for $arch/modules.o which
	turned into common/modules.c which triggered the gen rule.

	My local testing of this code didn't catch this bug because of how
	Automake manages .Po (dependency files) in incremental builds -- it
	was adding extra rules that override the pattern rules which caused
	the build to generate correct modules.c files.  But when building
	from a cold cache, the pattern rules would force common/modules.c to
	be used leading to crashes at runtime.

	sim: m32r: fix typos in stamp depends
	Copying & pasting the first rule missed updating the dep to the right
	stamp file.

	sim: igen: simplify build logic a little
	Now that all ports (that use igen) build in the top-level and depend
	on igen, we can move the conditional logic out of configure.  We also
	switch from noinst_LIBRARIES to EXTRA_LIBRARIES so that the library
	is only built when needed (i.e. the igen tool is used).

	sim: build: drop depdir subdir hack
	Now that all the ports compile some C files in their arch dirs, Automake
	guarantees creating the depdir for us, so we can drop our configure hack.

	sim: common: simplify modules.c deps
	Now that all ports (other than ppc) build in the top-level, we don't
	need to expand all the modules.c targets as a recursive dep.  Each
	port depends on their respective file now, and the ppc port doesn't
	use it at all.

	sim: common: move modules.c to source tracking
	This makes sure the arch-specific modules.c wildcard is matched and
	not the common/%.c so that we compile it correctly.  It also makes
	sure each subdir has depdir logic enabled.

	sim: common: move libcommon.a dep to ppc code
	Rather than force this to be built ahead of time for all targets,
	move the dep to the ppc code since it's the only user of it now.

	sim: build: drop most recursive build deps
	Now that we build these objects in the top dir & generate modules.c
	there, we don't need to generate them all first -- we can let the
	normal dependency graph take care of building things in parallel.

	sim: common: move libcommon.a objects to sources
	This simplifies the build logic and avoids an Automake bug where the
	common_libcommon_a_OBJECTS variable isn't set in the arch libsim.a
	DEPENDENCIES for targets that, alphabetically, come before "common".
	We aren't affected by that bug with the current code, but as we move
	things out of SIM_ALL_RECURSIVE_DEPS and rely on finer dependencies,
	we will trip over it.

	sim: igen: simplify build dep
	Now that all ports (other than ppc) build in the top-level, we don't
	need to mark the igen tool as a recursive dep.  Each port depends on
	the tool if it actually uses it, and ppc doesn't use it at all.

	sim: common: simplify hw-config.h deps
	Now that all ports (other than ppc) build in the top-level, we don't
	need to expand all the hw-config.h targets as a recursive dep.  Each
	port depends on their respective header now, and the ppc port doesn't
	use it at all.

	sim: build: drop AM_MAKEFLAGS settings
	We don't have any recursive builds anymore, so we can drop this logic.

	Pass internal gdb flags to --configuration invocations
	The test suite uses the --configuration flag to feature-test gdb.
	However, when I added this, I neglected to pass the internal gdbflags
	to this, causing an error, which then caused failures in the test
	suite (which would not be seen if you'd ever run "make install").

	This patch fixes the bug.  Tested by removing my install tree first,
	to verify that I could reproduce the failure.

	Rename to allow_tui_tests
	This changes skip_tui_tests to invert the sense, and renames it to
	allow_tui_tests.  It also rewrites this function to use the output of
	"gdb --configuration", and it adds a note about the state of the TUI
	to that output.

	Rename to allow_guile_tests
	This changes skip_guile_tests to invert the sense, and renames it to
	allow_guile_tests.  It also rewrites this proc to check the output of
	"gdb --configuration", as was done for Python.  Then it changes the
	code to use "require" where possible.

	Rename to allow_hw_breakpoint_tests
	This changes skip_hw_breakpoint_tests to invert the sense, and renames

	renames it to allow_hw_watchpoint_access_tests.

	This changes skip_go_tests to invert the sense, and renames it to
	allow_go_tests.

	Rename to allow_gdbserver_tests

	to allow_debuginfod_tests.

	Rename to allow_ctf_tests

	allow_ctf_tests.

	Rename to allow_cplus_tests and allow_stl_tests
	This changes skip_cplus_tests to invert the sense, and renames it to
	allow_cplus_tests.  This one also converts skip_stl_tests to
	allow_stl_tests, as that was convenient to do at the same time.

	Rename to allow_btrace_tests
	This changes skip_btrace_tests to invert the sense, and renames it to
	allow_btrace_tests.

	Rename to allow_btrace_pt_tests

	This changes various tests to use "require" for the Python feature.

2023-01-13  Tom Tromey  <tom@tromey.com>

	Fix latent bug in default_prompt_gdb_start
	default_prompt_gdb_start mimics default_gdb_start, but does not set
	the use_gdb_stub global.  This caused one Python test to work only
	because it used the ordinary gdb_start before later using
	default_prompt_gdb_start.

	This patch updates default_prompt_gdb_start to set this global as
	well.

2023-01-13  Tom Tromey  <tom@tromey.com>

	Remove mi_skip_python_tests
	mi_skip_python_tests was necessary because skip_python_tests used the
	running gdb, and so needed to know what prompt to expect.  Now that
	skip_python_tests has been rewritten, mi_skip_python_tests is no
	longer needed.

	Rewrite skip_python_tests
	This rewrites skip_python_tests to examine the output of
	"gdb --configuration".  This is a bit nicer because it
	does not require an already-running gdb.

	Use unsupported in 'require'
	This changes 'require' to use 'unsupported' rather than 'untested'.
	The latter doesn't really seem to be correct according to the DejaGNU
	documentation:

	    Declares a test was not run.  `untested' writes in the log file a
	    message beginning with _UNTESTED_, appending the `message' argument.
	    For example, you might use this in a dummy test whose only role is to
	    record that a test does not yet exist for some feature.

	The example there, and some text elsewhere, is what makes me think
	this isn't a great fit.  On the other hand, 'unsupported' says:

	    Declares that a test case depends on some facility that does not exist
	    in the testing environment.

2023-01-13  Tom Tromey  <tom@tromey.com>

	Change 'require' to accept a list of predicates
	This changes 'require' to accept a list of simple predicates.  For
	now, each predicate is just the name of a proc, optionally prefixed
	with "!" to indicate that the result should be inverted.

	It's possible to make this fancier, but so far I haven't done so.  One
	idea I had is to allow a predicate to have associated text to display
	on failure.  Another is to convert the predicates that need a running
	gdb (e.g., skip_python_tests) to start their own gdb, and then
	'require' could enforce the rule that gdb not be running when it is
	called.

2023-01-13  Tom Tromey  <tom@tromey.com>

	Don't use ensure_gdb_index with require

	Disable ptype/o for dynamic types
	A user pointed out that "ptype/o" of a certain Ada type -- while in C
	mode -- caused gdb to crash.

	The bug here is that dynamic types can't really be printed this way.
	This patch avoids the bug by disabling the "/o" feature in this case.

	Note that using "ptype/o" in this way makes sense for the time being,
	because the Ada code doesn't support the "/o" feature (yet); and in
	any case gdb should not crash.

	ARM: Fix ld bloat introduced between binutils-2.38 and 2.39
	Since commit 9833b7757d24, "PR28824, relro security issues",
	ELF_MAXPAGESIZE matters much more, with regards to layout of
	the linked file.  That commit fixed an actual bug, but also
	exposes a problem for targets were that value is too high.

	For example, for ARM(32, a.k.a. "Aarch32") specifically
	bfd_arch_arm, it's set to 64 KiB, making all Linux(/GNU)
	targets pay an extra amount of up to 60 KiB of bloat in
	DSO:s and executables.  This matters when there are many
	such files, and where storage is expensive.

	It's *mostly* bloat when using a Linux kernel, as ARM(32) is
	a good example of an target where ELF_MAXPAGESIZE is set to
	an extreme value for an obscure corner-case.  The ARM
	(32-bit) kernel has 4 KiB pages, has had that value forever,
	and can't be configured to any other value.  The use-case is
	IIUC "Aarch32" emulation on an "Aarch64" (arm64) kernel, but
	not just that, but a setup where the Linux page-size is
	configured to something other than the *default* 4 KiB.  Not
	sure there actually any such systems in use, again with
	both Aarch32 compatibility support and a non-4KiB pagesize,
	with all the warnings in the kernel config and requiring the
	"EXPERT" level set on.

	So, let's do like x86-64 in a2267dbfc9e1 "x86-64: Use only
	one default max-page-size" and set ELF_MAXPAGESIZE to 4096.

	ld/testsuite: Adjust for ELF_MAXPAGESIZE 0x1000
	Many tests reflect a setting of ELF_MAXPAGESIZE to 64 KiB.
	With ELF_MAXPAGESIZE changed to 4 KiB, layout is sometimes
	different and symbols end up in other places.  Avoid churn
	and regexpification of old test patterns by passing the
	max-page-size setting active at the time.

	libctf: ctf-link outdated input check faulty
	This check has a pair of faults which, combined, can lead to memory
	corruption.  Firstly, it assumes that the values of the ctf_link_inputs
	hash are ctf_dict_t's: they are not, they are ctf_link_input_t's, a much
	shorter structure.  So the flags check which is the core of this is
	faulty (but happens, by chance, to give the right output on most
	architectures, since usually we happen to get a 0 here, so the test that
	checks this usually passes).  Worse, the warning that is emitted when
	the test fails is added to the wrong dict -- it's added to the input
	dict, whose warning list is never consumed, rendering the whole check
	useless.  But the dict it adds to is still the wrong type, so we end up
	overwriting something deep in memory (or, much more likely,
	dereferencing a garbage pointer and crashing).

	Fixing both reveals another problem: the link input is an *archive*
	consisting of multiple members, so we have to consider whether to check
	all of them for the outdated-func-info thing we are checking here.
	However, no compiler exists that emits a mixture of members with this
	flag on and members with it off, and the linker always reserializes (and
	upgrades) such things when it sees them: so all members in a given
	archive must have the same value of the flag, so we only need to check
	one member per input archive.

	try/catch and suppress the testsuite via an Automake conditional in its
	absence.

	But this turns out not to work: Automake produces a check-DEJAGNU target
	regardless of the value of this conditional and sticks it in an
	unconditionally-executed part of the makefile, so the testsuite gets
	executed anyway, and fails with a nasty-looking syntax error.  We can't
	disable it by taking "dejagnu" out of AUTOMAKE_OPTIONS, because if you
	do that Automake stops you using RUNTEST, RUNTESTFLAGS and other
	variables users would expect to work.

	So move to disabling the testsuite from inside the testsuite itself,
	importing the value of the former Automake conditional as a Tcl variable
	and exiting very early in default.exp if it's false.

		* configure.ac (TCL_TRY): No longer an Automake conditional.
		Rename to...
		(HAVE_TCL_TRY): ... this.
		* Makefile.am: Drop TCL_TRY.
		(development.exp): Set have_tcl_try.
		* testsuite/config/default.exp: Exit if have_tcl_try is false.

		* configure: Regenerated.
		* Makefile.in: Likewise.

	ctf: fix various dreadful typos in the ctf_archive format comments
	When defining a format it helps to a) get the endianness right when you
	explicitly state what it is and b) define things in terms of fields that
	exist rather than fields that don't.

	(A bunch of changes of names during implementation were not reflected in
	these comments...)

	Thanks to Jose "Eye of the Eagle" Marchesi for spotting these.

	include/
		* ctf.h (struct ctf_archive) [ctfa_ctfs]: The size element of
		this is in little-endian byte order, not network byte order.
		(struct ctf_archive_modent): This is positioned right after the
		end fo the struct ctf_archive, not at the offset of a
		nonexistent field.  The number of elements in the array depends
		on ctfa_ndicts, not another nonexistent field.

	Set _WIN32_WINNT in common.m4 configure check
	GCC recently added support for the Windows thread model, enabling
	libstdc++ to support Windows natively.  However, this supporrt
	requires a version of Windows later than the minimum version that is
	supported by GDB.

	PR build/29966 points out that the GDB configure test for std::thread
	does not work in this situation, because _WIN32_WINNT is not defined
	in test program, and so <thread> seems to be fine.

	This patch is an attempt to fix the problem, by using the same setting
	for _WIN32_WINNT at configure time as is used at build time.

	I don't have access to one of the older systems so I don't think I can
	truly test this.  I did do a mingw cross build, though.  I'm going to
	ask the bug reporter to test it.

	[gdb/testsuite] Fix gdb.threads/dlopen-libpthread.exp for upstream glibc, again
	On an x86_64 laptop running ubuntu 22.04.1 with unity desktop:
	...
	$ echo $XDG_CURRENT_DESKTOP
	Unity:Unity7:ubuntu
	...
	I have:
	...
	$ echo $LD_PRELOAD
	libgtk3-nocsd.so.0
	...
	due to package gtk3-nocsd, a package recommended by unity-session.

	Consequently, for each exec these dependencies are pulled in, including
	libpthread.so.0:
	...
	$ lddtree /lib/x86_64-linux-gnu/libgtk3-nocsd.so.0
	libgtk3-nocsd.so.0 => /lib/x86_64-linux-gnu/libgtk3-nocsd.so.0 (interpreter => none)
	    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2
	    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
	    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6
	        ld-linux-x86-64.so.2 => /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
	...

	So, while test-case gdb.threads/dlopen-libpthread.exp appears to run ok:
	...
	 # of expected passes		12
	 # of unsupported tests		1
	...
	with LD_PRELOAD="" we have instead:
	...
	(gdb) PASS: gdb.threads/dlopen-libpthread.exp: continue to breakpoint: notify
	info sharedlibrary^M
	From  To                  Syms Read   Shared Object Library^M
	$hex  $hex  Yes         /lib64/ld-linux-x86-64.so.2^M
	$hex  $hex  Yes         /lib/x86_64-linux-gnu/libc.so.6^M
	$hex  $hex  Yes         dlopen-libpthread.so^M
	(gdb) FAIL: gdb.threads/dlopen-libpthread.exp: libpthread.so found
	...

	The problem is that libpthread is expected as dependency of
	dlopen-libpthread.so, but it's missing:
	...
	$ lddtree dlopen-libpthread.so
	dlopen-libpthread.so => ./dlopen-libpthread.so (interpreter => none)
	    libc.so.6 => $outputs/gdb.threads/dlopen-libpthread/dlopen-libpthread.so.d/libc.so.6
	        ld-linux-x86-64.so.2 => /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
	...
	due to having glibc 2.35, which has libpthread integrated into libc.

	Fix this by:
	- adding a proc has_dependency
	- using [has_dependency $exec libpthread.so] as hint that libpthread
	  may be preloaded
	- using ![has_dependency $shlib libpthread.so] to detect that
	  the libpthread.so dependency is missing.

	Also add a missing return after untested "no matching probes".

	Tested on x86_64-linux, with and without LD_PRELOAD="".

	gas/RISC-V: adjust assembler for opcode table re-ordering
	PR gas/29940

	With the single-operand JAL entry now sitting ahead of the two-operand
	one, the parsing of a two-operand insn would first try to parse an 'a'-
	style operand, resulting in the insertion of bogus (and otherwise
	unused) undefined symbols in the symbol table, having register names.
	Since 'a' is used as 1st operand only with J and JAL, and since JAL is
	the only insn _also_ allowing for a register as 1st operand (and then
	there being a 2nd one), special case this parsing aspect right there.

	needed for PDBs, and the SEH pseudos used for C++ exceptions.

	This first patch fixes the size of RELSZ; I'm not sure why it was 14 in
	the first place. This is the size of the "Base Relocation Block" in

	gdb/dwarf2: Fix 'rw_pieced_value' for values casted to different type.
	The 'rw_pieced_value' function is executed when fetching a (lazy)
	variable described by 'DW_OP_piece' or 'DW_OP_bit_piece'.  The
	function checks the 'type' and 'enclosing_type' fields of the value
	for identity.

	  * The 'type' field describes the type of a value.
	  * In most cases, the 'enclosing_type' field is identical to the
	    'type' field.
	  * Scenarios where the 'type' and 'enclosing_type' of an object
	    differ are described in 'gdb/value.c'.  Possible cases are:
	    * If a value represents a C++ object, then the 'type' field
	      gives the object's compile-time type.  If the object actually
	      belongs to some class derived from `type', perhaps with other
	      base classes and additional members, then `type' is just a
	      subobject of the real thing, and the full object is probably
	      larger than `type' would suggest.
	    * If 'type' is a dynamic class (i.e. one with a vtable), then GDB
	      can actually determine the object's run-time type by looking at
	      the run-time type information in the vtable.  GDB may then elect
	      to read the entire object.
	    * If the user casts a variable to a different type
	      (e.g. 'print (<type> []) <variable>'), the value's type is
	      updated before reading the value.

	If a lazy value is fetched, GDB allocates space based on the enclosing
	type's length and typically reads the 'full' object.  This is not
	implemented for pieced values and causes an internal error if 'type'
	and 'enclosing_type' of a value are not identical.

	However, GDB can read the value based on its type.  Thus, this patch
	fixes the previously mentioned cases by removing the check for identity.

	The arch-specific flags are only used by the arch-specific modules,

	The code so far has been assuming that we only compile common/ objects.
	Now that we're ready to compile arch-specific objects, refactor some of
	the flags & checks a bit to support both.

	sim: modules.c: move generation to top-level
	Now that all arches create libsim.a from the top-level, we have full
	access to their inputs, and can move the actual generation from the
	subdir up to the top-level.  This avoids recursive makes and will
	help simplify state passing between the two.

	sim: build: drop common/nrun.o subdir hack
	Now that all the subdirs handle their own builds, we can drop this
	common rule as it's unused, and we don't want to use it anymore.

	sim: build: drop support for creating libsim.a in subdirs
	Now that all ports have moved to creating libsim.a in the top-level,
	drop all the support code to create it in a subdir.

	sim: v850: move libsim.a creation to top-level
	The objects are still compiled in the subdir, but the creation of the

	This currently builds off of the objects that go into the libsim.a as

	gdb/linespec.c: Fix missing source file during breakpoint re-set
	During breakpoint re-setting, the source_filename of an
	explicit_location_spec is used to lookup the symtabs associated with
	the breakpoint being re-set.  This source_filename is compared with each
	known symtab filename in order to retrieve the breakpoint's symtabs.

	However the source_filename may have been originally copied from a
	symtab's fullname (the path where GDB found the source file) when the
	breakpoint was first created.  If a breakpoint symtab's filename and
	fullname differ and there is no substitute-path rule that converts the
	fullname to the filename, this will cause a NOT_FOUND_ERROR to be thrown
	during re-setting.

	Fix this by using a symtab's filename to set the explicit_location_spec
	source_filename instead of the symtab's fullname.

	Move bfd_init to bfd.c
	init.c contains just one function that doesn't do much.  Move it to
	bfd.c and give it something to do, initialising static state.  So far
	the only initialisation is for bfd.c static variables.

	The idea behind reinitialising state is to see whether some set of
	flaky oss-fuzz crashes go away.  oss-fuzz stresses binutils in ways
	that can't occur in reality, feeding multiple testcases into the
	internals of binutils.  So one testcase may affect the result of the

	testsuite: add -O0 to Intel compilers if no 'optimize' option is given
	icpx/icx give the following warning if '-g' is used without '-O'.

	   icpx: remark: Note that use of '-g' without any optimization-level
	   option will turn off most compiler optimizations similar to use of
	   '-O0'; use '-Rno-debug-disables-optimization' to disable this
	   remark [-Rdebug-disables-optimization]

	The warning makes dejagnu think that compilation has failed.  E.g.:

	  $ make check TESTS="gdb.cp/local.exp" RUNTESTFLAGS="CXX_FOR_TARGET='icpx' CC_FOR_TARGET=icx"
	  ...
	  gdb compile failed, icpx: remark: Note that use of '-g' without any optimization-level option will turn off most compiler optimizations similar to use of '-O0'; use '-Rno-debug-disables-optimization' to disable this remark [-Rdebug-disables-optimization]

	                  === gdb Summary ===

	  # of untested testcases         1

	Furthermore, if no -O flag is passed, icx/icc optimize
	the code by default.  This breaks assumptions in many GDB tests
	that the code is unoptimized by default.  E.g.:

	  $ make check TESTS="gdb.cp/cmpd-minsyms.exp" RUNTESTFLAGS="CXX_FOR_TARGET='icpx' CC_FOR_TARGET=icx"
	  ...

	  # of unexpected failures        9

	To fix both problems, pass the -O0 flag explicitly, if no optimization
	option is given.

	With this patch we get, e.g.:

	  of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended

	As the testsuite compile fails when unexpected output by the compiler is
	seen this change in the compiler breaks all existing icc and icpc tests.
	This patch makes the gdb testsuite more forgiving by a) allowing the

	libsframe: adjust an incorrect check in flip_sframe
	When sframe_encoder_write needs to flip the buffer containing the SFrame
	section before writing, it is not necessary that the SFrame FDES are in
	the order of their sfde_func_start_fre_off.  On the contrary, SFrame
	FDEs will be sorted in the order of their start address.  So, remove
	this incorrect assumption which is basically assuming that the last
	sfde_func_start_fre_off seen will help determine the end of the flipped
	buffer.

	The function now keeps track of the bytes_flipped and then compares it with
	the expected value.  Also, added two more checks at appropriate places:
	 - check that the SFrame FDE read is within bounds
	 - check that the SFrame FRE read is within bounds

	gdb/c++: Detect ambiguous variables in imported namespaces
	When running gdb.cp/nsusing.cc and stopping at line 17, we can ask GDB
	to print x and get a compiler-dependent answer. Using gcc 12.2.1, GDB
	will print M::x, and using clang 16.0.0 prints N::x. Not only is this
	behavior confusing to users, it is also not consistent with compiler
	behaviors, which would warn that using x is ambiguous at this point.

	This commit makes GDB behavior consistent with compilers. it achieves
	this by making it so instead of exiting early when finding any symbol
	with the correct name, GDB continues searching through all include
	directives, storing all matching symbols in a relational map betwen the
	mangled name and the found symbols.

	If the resulting map has more than one entry, GDB says that the
	reference is ambiguous and lists all possibilities. Otherwise it returns
	the block_symbol structure for the desired symbol, or an empty struct if
	nothing was found.

	The commit also changes gdb.cp/nsusing.exp to test the ambiguous
	detection.

	gdbsupport: fix scoped_debug_start_end's move constructor
	I spotted a problem with scoped_debug_start_end's move constructor.
	When constructing a scoped_debug_start_end through it, it doesn't
	disable the moved-from object, meaning there are now two objects that
	will do the side-effects of decrementing the debug_print_depth global
	and printing the "end" message.  Decrementing the debug_print_depth
	global twice is actually problematic, because the increments and
	decrements get out of sync, meaning we should hit this assertion, in
	theory:

	    gdb_assert (debug_print_depth > 0);

	However, in practice, we don't see that.  This is because despite the
	move constructor being required for this to compile:

	    template<typename PT>
	    static inline scoped_debug_start_end<PT &> ATTRIBUTE_NULL_PRINTF (6, 7)
	    make_scoped_debug_start_end (PT &&pred, const char *module, const char *func,
	    			     const char *start_prefix,
	    			     const char *end_prefix, const char *fmt, ...)
	    {
	      va_list args;
	      va_start (args, fmt);
	      auto res = scoped_debug_start_end<PT &> (pred, module, func, start_prefix,
	    					   end_prefix, fmt, args);
	      va_end (args);

	      return res;
	    }

	... it is never actually called, because compilers elide the move
	constructors all the way (the scoped_debug_start_end gets constructed
	directly in the instance of the top-level caller).  To confirm this, I
	built GDB with -fno-elide-constructors, and now I see it:

	    /home/simark/src/binutils-gdb/gdb/../gdbsupport/common-debug.h:147: internal-error: ~scoped_debug_start_end: Assertion `debug_print_depth > 0' failed.

	Fix this by adding an m_disabled field to scoped_debug_start_end, and

	gdb: make gdbarch_alloc take ownership of the tdep
	It's currently not clear how the ownership of gdbarch_tdep objects
	works.  In fact, nothing ever takes ownership of it.  This is mostly
	fine because we never free gdbarch objects, and thus we never free
	gdbarch_tdep objects.  There is an exception to that however: when
	initialization fails, we do free the gdbarch object that is not going to
	be used, and we free the tdep too.  Currently, i386 and s390 do it.

	To make things clearer, change gdbarch_alloc so that it takes ownership
	of the tdep.  The tdep is thus automatically freed if the gdbarch is
	freed.

	Change all gdbarch initialization functions to pass a new gdbarch_tdep
	object to gdbarch_alloc and then retrieve a non-owning reference from
	the gdbarch object.

	Before this patch, the xtensa architecture had a single global instance
	of xtensa_gdbarch_tdep.  Since we need to pass a dynamically allocated
	gdbarch_tdep_base instance to gdbarch_alloc, remove this global
	instance, and dynamically allocate one as needed, like we do for all
	other architectures.  Make the `rmap` array externally visible and
	rename it to the less collision-prone `xtensa_rmap` name.

	      gdb: use libbacktrace to create a better backtrace for fatal signals

	The code is trying to select between using libbacktrace or using the
	execinfo supplied backtrace API.

	First we check to see if we can use libbacktrace.  If we can then we
	include some header files, and then set some defines to indicate that
	libbacktrace is being used.

	Then we check if execinfo is available, if it is then we include
	<execinfo.h> and set some alternative defines.

	In theory the second block of logic should not trigger if the first
	block (that uses libbacktrace) has also triggered, but we incorrectly
	check the define 'PRINT_BACKTRACE_ON_FATAL_SIGNAL' instead of checking
	for 'GDB_PRINT_INTERNAL_BACKTRACE_USING_LIBBACKTRACE', so the second
	block triggers more than it should.  The
	'PRINT_BACKTRACE_ON_FATAL_SIGNAL' define is not defined anywhere, this
	was a mistake in the original commit.

	In reality this is harmless, we include <execinfo.h> when we don't
	need too, but in by-utils.c the libbacktrace define is always checked
	for before the execinfo define, so we never actually end up using the
	execinfo path (when libbacktrace is available).  But I figure its
	still worth cleaning this up.

	I've tested GDB in a "default" build where libbacktrace is used, and
	when configuring with --disable-libbacktrace which causes the execinfo
	backtrace API to be used instead, both still appear to work fine.

	There should be no user visible changes after this commit.

	Avoid unaligned pointer reads in PEP .idata section
	This is something I discovered when working on aarch64, though it's
	relevant to x86_64 too.

	The PE32+ imports are located in the .idata section, which starts off
	with a 20-byte structure for each DLL, containing offsets into the rest
	of the section. This is the Import Directory Table in
	https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, which
	is a concatenation of the .idata$2 sections. This is then followed by an
	20 zero bytes generated by the linker script, which calls this .idata$3.

	After this comes the .idata$4 entries for each function, which the
	loader overwrites with the function pointers. Because there's no padding
	between .idata$3 and .idata$4, this means that if there's an even number
	of DLLs, the function pointers won't be aligned on an 8-byte boundary.

	Misaligned reads are slower on x86_64, but this is more important on
	aarch64, as the e.g. `ldr x0, [x0, :lo12:__imp__func]` the compiler
	might generate requires __imp__func (the .idata$4 entry) to be aligned
	to 8 bytes. Without this you get IMAGE_REL_ARM64_PAGEOFFSET_12L overflow
	errors.

	Add test case for "finish" with variably-sized types
	This adds a test case for "finish" with variably-sized types, and for
	inferior calls as well.  This also extends the "runto" proc to handle
	temporary breakpoints.

	Use value_at_non_lval in get_call_return_value
	get_call_return_value can handle RETURN_VALUE_STRUCT_CONVENTION,
	because the call is completely managed by gdb.  However, it does not
	handle variably-sized types correctly.  The simplest way to fix this
	is to use value_at_non_lval, which does type resolution.

	Fix inferior calls with variably-sized return type
	This patch updates the gdbarch_return_value_as_value implementations
	to work correctly with variably-sized return types.

	Convert selected architectures to gdbarch_return_value_as_value
	This converts a few selected architectures to use
	gdbarch_return_value_as_value rather than gdbarch_return_value.  The

	should not introduce any behavior changes.

2023-01-03  Tom Tromey  <tromey@adacore.com>

	Don't let property evaluation affect the current language
	On PPC, we saw that calling an inferior function could sometimes
	change the current language, because gdb would select the call dummy
	frame -- associated with _start.

	This patch changes gdb so that the current language is never affected
	by DWARF property evaluation.

2023-01-03  Tom Tromey  <tromey@adacore.com>

	Introduce value_at_non_lval
	In some cases, while a value might be read from memory, gdb should not
	record the value as being equivalent to that memory.

	In Ada, the inferior call code will call ada_convert_actual -- and
	here, if the argument is already in memory, that address will simply
	be reused.  However, for a call like "f(g())", the result of "g" might
	be on the stack and thus overwritten by the call to "f".

	This patch introduces a new function that is like value_at but that
	ensures that the result is non-lvalue.

2023-01-03  Tom Tromey  <tromey@adacore.com>

	Don't emit gdbarch_return_value
	The previous patch introduced a new overload of gdbarch_return_value.
	The intent here is that this new overload always be called by the core
	of gdb -- the previous implementation is effectively deprecated,
	because a call to the old-style method will not work with any
	converted architectures (whereas calling the new-style method is will
	delegate when needed).

	This patch changes gdbarch.py so that the old gdbarch_return_value
	wrapper function can be omitted.  This will prevent any errors from
	creeping in.

2023-01-03  Tom Tromey  <tromey@adacore.com>

	Add new overload of gdbarch_return_value
	The gdbarch "return_value" can't correctly handle variably-sized
	types.  The problem here is that the TYPE_LENGTH of such a type is 0,
	until the type is resolved, which requires reading memory.  However,
	gdbarch_return_value only accepts a buffer as an out parameter.

	Fixing this requires letting the implementation of the gdbarch method
	resolve the type and return a value -- that is, both the contents and
	the new type.

	After an attempt at this, I realized I wouldn't be able to correctly
	update all implementations (there are ~80) of this method.  So,
	instead, this patch adds a new method that falls back to the current
	method, and it updates gdb to only call the new method.  This way it's
	possible to incrementally convert the architectures that I am able to
	test.

	works when building objects recursively in subdirs.  As we move those
	out to the top-level, we don't have any recursive steps anymore.  The
	Automake approach is to declare those headers in BUILT_SOURCES.

	This isn't completely foolproof as the Automake manual documents: it
	only activates for `make all`, not `make foo.o`, but that shouldn't be
	a huge limitation as it only affects the initial compile.  After that,
	rebuilds should work fine.

	Initial implementation of Debugger Adapter Protocol
	The Debugger Adapter Protocol is a JSON-RPC protocol that IDEs can use
	to communicate with debuggers.  You can find more information here:

	    https://microsoft.github.io/debug-adapter-protocol/

	Frequently this is implemented as a shim, but it seemed to me that GDB
	could implement it directly, via the Python API.  This patch is the
	initial implementation.

	DAP is implemented as a new "interp".  This is slightly weird, because
	it doesn't act like an ordinary interpreter -- for example it doesn't
	implement a command syntax, and doesn't use GDB's ordinary event loop.
	However, this seemed like the best approach overall.

	To run GDB in this mode, use:

	    gdb -i=dap

	The DAP code will accept JSON-RPC messages on stdin and print
	responses to stdout.  GDB redirects the inferior's stdout to a new
	pipe so that output can be encapsulated by the protocol.

	The Python code uses multiple threads to do its work.  Separate
	threads are used for reading JSON from the client and for writing JSON
	to the client.  All GDB work is done in the main thread.  (The first
	implementation used asyncio, but this had some limitations, and so I
	rewrote it to use threads instead.)

	This is not a complete implementation of the protocol, but it does
	implement enough to demonstrate that the overall approach works.

	There is a rudimentary test suite.  It uses a JSON parser written in
	pure Tcl.  This parser is under the same license as Tcl itself, so I
	felt it was acceptable to simply import it into the tree.

	There is also a bit of documentation -- just documenting the new
	interpreter name.

	The cced7cacecad104fff0 ("gdb: preserve `|` in connection details string")
	commit added '|' detection and removal to ser-pipe.c, but missed to add it
	to ser-mingw.c.

	This results in the error message below for MinGW hosts:
	error starting child process '| <executable> <args>': CreateProcess: No such file or directory

	This commit add the missing '|' detection and removal to ser-mingw.c.

	Remove target: prefix from gdb_sysroot in find_separate_debug_file
	I noticed that, when using gdbserver, gdb might print:

	Reading /usr/lib/debug/lib64//libcap.so.2.48-2.48-4.fc36.x86_64.debug from remote target...
	Reading target:/usr/lib/debug/lib64//libcap.so.2.48-2.48-4.fc36.x86_64.debug from remote target...

	The second line has the "target:" prefix, but from the code it's clear
	that this string is being passed verbatim to gdbserver -- which seems
	wrong.

	I filed PR remote/29929 for this.

	The problem here is that find_separate_debug_file uses gdb_sysroot
	without checking to see if it starts with the "target:" prefix.  This
	patch changes this code to be a little more careful.

	ld: Handle LF_VFTABLE types in PDBs

2022-12-31  Mark Harmstone  <mark@harmstone.com>

	ld: Handle extended-length data structures in PDB types
	A few fixes to minor issues I've discovered in my PDB patches.

	* If sizes or offsets are greater than 0x8000, they get encoded as
	extended values in the same way as for enum values - e.g. a LF_ULONG
	.short followed by a .long.

	* I've managed to coax MSVC to produce another type, LF_VFTABLE, which
	is seen when dealing with COM. I don't think LLVM emits this. Note that
	we can't just implement everything in Microsoft's header files, as most
	of it is obsolete.

	* Fixes a stupid bug in the test program, where I was adding an index to
	a size. The index was hard-coded to 0, so this didn't cause any actual
	issues.

	[gdb/python] Fix gdb.python/py-finish-breakpoint2.exp for -m32
	[ Partial resubmission of an earlier submission by Andrew (
	https://sourceware.org/pipermail/gdb-patches/2012-September/096347.html ), so
	listing him as co-author. ]

	With x86_64-linux and target board unix/-m32, we have:
	...
	(gdb) continue^M
	Continuing.^M
	Exception #10^M
	^M
	Breakpoint 3, throw_exception_1 (e=10) at py-finish-breakpoint2.cc:23^M
	23        throw new int (e);^M
	(gdb) FAIL: gdb.python/py-finish-breakpoint2.exp: \
	  check FinishBreakpoint in catch()
	...

	The following scenario happens:
	- set breakpoint in throw_exception_1, a function that throws an exception
	- continue
	- hit breakpoint, with call stack main.c:38 -> throw_exception_1
	- set a finish breakpoint
	- continue
	- hit the breakpoint again, with call stack main.c:48 -> throw_exception
	  -> throw_exception_1

	Due to the exception, the function call did not properly terminate, and the
	finish breakpoint didn't trigger.  This is expected behaviour.

	However, the intention is that gdb detects this situation at the next stop
	and calls the out_of_scope callback, which would result here in this test-case
	in a rather confusing "exception did not finish" message.  So the problem is
	that this message doesn't show up, in other words, the out_of_scope callback
	is not called.

	[ Note that the fact that the situation is detected only at the next stop
	(wherever that happens to be) could be improved upon, and the earlier
	submission did that by setting a longjmp breakpoint.  But I'm considering this
	problem out-of-scope for this patch. ]

	Note that the message does show up later, at thread exit:
	...
	[Inferior 1 (process 20046) exited with code 0236]^M
	exception did not finish ...^M
	...

	The decision on whether to call the out_of_scope call back is taken in
	bpfinishpy_detect_out_scope_cb, and the interesting bit is here:
	...
	             if (b->pspace == current_inferior ()->pspace
	                 && (!target_has_registers ()
	                     || frame_find_by_id (b->frame_id) == NULL))
	               bpfinishpy_out_of_scope (finish_bp);
	...

	In the case of the thread exit, the callback triggers because
	target_has_registers () == 0.

	So why doesn't the callback trigger in the case of the breakpoint?

	Well, the b->frame_id is the frame_id of the frame of main (the frame
	in which the finish breakpoint is supposed to trigger), so AFAIU
	frame_find_by_id (b->frame_id) == NULL will only be true once we've
	left main, at which point I guess we don't stop till thread exit.

	Fix this by saving the frame in which the finish breakpoint was created, and
	using frame_find_by_id () == NULL on that frame instead, such that we have:
	...
	(gdb) continue^M
	Continuing.^M
	Exception #10^M
	^M
	Breakpoint 3, throw_exception_1 (e=10) at py-finish-breakpoint2.cc:23^M
	23        throw new int (e);^M
	exception did not finish ...^M
	(gdb) FAIL: gdb.python/py-finish-breakpoint2.exp: \
	  check FinishBreakpoint in catch()
	...

	Still, the test-case is failing because it's setup to match the behaviour that
	we get on x86_64-linux with target board unix/-m64:
	...
	(gdb) continue^M
	Continuing.^M
	Exception #10^M
	stopped at ExceptionFinishBreakpoint^M
	(gdb) PASS: gdb.python/py-finish-breakpoint2.exp: \
	  check FinishBreakpoint in catch()
	...

	So what happens here?  Again, due to the exception, the function call did not
	properly terminate, but the finish breakpoint still triggers.  This is somewhat
	unexpected.  This happens because it just so happens to be that the frame
	return address at which the breakpoint is set, is also the first instruction
	after the exception has been handled.  This is a know problem, filed as
	PR29909, so KFAIL it, and modify the test-case to expect the out_of_scope
	callback.

	Also add a breakpoint after setting the finish breakpoint but before throwing
	the exception, to check that we don't call the out_of_scope callback too early.

	Tested on x86_64-linux, with target boards unix/-m32.

	sim: build: clean up unused codegen logic
	Now that all igen ports are in the top-level makefile, we don't need
	this logic in any subdirs anymore, so clean it up.

	sim: mips: hoist "multi" igen rules up to common builds
	Since these are the last mips igen rules, we can clean up a number of
	bits in the local Makefile.in.

	sim: mips: hoist "m16" igen rules up to common builds

	sim: mips: hoist "single" igen rules up to common builds

	sim: mips: rename "igen" generation mode to "single"
	The naming in here has grown organically and is confusing to follow.
	Originally there was only one set of rules for generating code from
	the igen sources, so calling it "tmp-igen" and such made sense.  But
	when other multigen modes were added ("m16" & "multi") which also
	used igen, it's not clear what's common igen and what's specific to
	this generation  mode.  So rename the set of rules from "igen" to
	"single" so it's easier to follow.

	sim: mips: hoist itable igen rules up to common builds
	Since this rule is pretty simple, hoist it up to the common build.

2022-12-27  Mike Frysinger  <vapier@gentoo.org>

	sim: mips: unify itable generation (a bit)
	The m16 & multi targets generate itable once even when all the other
	modules are generated multiple times.  The default igen target will
	generate itable with everything else out of convenience.  This means
	flags are passed which don't affect the generated itable there.

	We can unify the itable generation by making sure the right -F/-M
	filter variables are passed down.  Since there's already a dedicated
	rule & variable in the multi build mode, generalize that and switch
	the m16 & igen builds over too.

	I spent a lot of time staring at this code, building for diff mips
	targets, and exploring all the shell code paths.  I think this is
	safe, but only time (and users) will really tell.

2022-12-27  Mike Frysinger  <vapier@gentoo.org>

	sim: mips: rename multi_flags to igen_itable_flags
	This variable is only used to generate the itable files.  In preparation
	for merging the itable logic among all ports, rename "multi_flags" to a
	more appropriate "igen_itable_flags" variable.  There should be no real
	chagnes here otherwise.

	sim: mips: drop unused micromips igen logic
	This code appears to be unused since it was first merged.  When
	micromips was enabled, it was via the "MULTI" config, not the
	"MICROMIPS" config, and the multi configs have sep vars.  Since
	nothing sets SIM_MIPS_GEN=MICROMIPS in the config, all of this
	should be unreachable, so punt it to simplify.  Further, the
	SIM_MIPS_MICROMIPS16_FLAGS & SIM_MIPS_MICROMIPS_FLAGS settings
	rely on sim_mips_micromips{,16}_{filter,machine} variables that
	are never set in the configure script.

	libsframe: write out SFrame FRE start address correctly
	The following test was failing on ppc64 and s390x:

	The offending stub was how we memcpy the FRE start address to the buffer
	(on-disk format).  When the host is big-endian, the address of the
	source buffer for the memcpy needs to point to the uint8_t/uint16_t sized
	value of the FRE start addr, not uint32_t sized value; we intend to copy
	out only the fre_start_addr_sz number of bytes.

		(sframe_encoder_write_fre): Use it instead of memcpy.

	sim: smp: plumb igen flag down to all users
	While mips has respected sim_igen_smp at configure time (which was
	always empty since it defaulted smp to off), no other igen port did.
	Move this to a makefile variable and plumb it through the common
	IGEN_RUN variable instead so everyone gets it by default.  We also
	clean up some redundant -N0 setting with multirun mips.

	sim: smp: make option available again
	At some point we want this to work, but it's not easy to test if
	the configure option isn't available.  Restore it, but keep the
	default off.

	sim: cpu: change default init to handle all cpus
	All the runtimes were only initializing a single CPU.  When SMP is
	enabled, things quickly crash as none of the other CPU structs are
	setup.  Change the default from 0 to the compile time value.

	sim: msp430: add basic SMP cpu init
	There's no need to assert there's only 1 CPU when setting them all
	up here is trivial.

	sim: m32r: fix iterator typo when setting up cpus
	This code loops over available cpus with "c", but then looks up the
	cpu with "i".  Fix the typo so the code works correctly with smp.

	sim: v850: fix SMP compile
	The igen tool sets up the SD & CPU defines for code fragments to use,
	but v850 was expecting "sd".  Change all the igen related code to use
	SD so it actually compiles, and fix a few places to use "CPU" instead
	of hardcoding cpu0.

	sim: or1k: fix iterator typo when setting up cpus
	This code loops over available cpus with "c", but then looks up the
	cpu with "i".  Fix the typo so the code works correctly with smp.

	sim: mn10300: fix SMP compile
	The igen tool sets up the SD define for code fragments to use, but
	mn10300 was expecting "sd".  Change all the igen related code to use
	SD so it actually compiles.

	sim: cpu: fix SMP msg prefix helper
	This code fails to compile when SMP is enabled due to some obvious
	errors.  Fix those and change the logic to avoid CPP to prevent any
	future rot from creeping back in.

	sim: mips: clean up a bit after mips/configure removal
	Now that there is no subdir configure script, we can clean up some
	logic that was spread between the files.

	sim: mips: move igen settings to top-level configure
	This is the last bit of logic that exists in the mips configure
	script, so move it to the top-level configure to kill it off.
	We still have to move the Makefile.in igen logic to local.mk,
	but this is a required first step for that.

	sim: mips: namespace igen configure vars
	To prepare moving this logic to the top-level configure, the vars
	need to be namespaced.  Do that here to make it easier to review.
	Basically sim_xxx -> SIM_MIPS_XXX when a var is exported from the
	configure script to the Makefile, and sim_xxx -> sim_mips_xxx when
	the var is internal in the configure script.

	sim: mips: add igen recursive dep
	Make sure the igen tool exists before trying to compile the mips
	subdir.  This happens to work when mips has a subconfigure, but
	hits a race condition when that is removed.

	sim: mips: drop unused ENGINE_ISSUE_POSTFIX_HOOK
	Nothing defines this, and it isn't called in all the engine runtimes,
	so drop it entirely to avoid confusion.

	sim: igen: drop move-if-changed usage
	Now that igen itself has this logic, drop these custom build rules
	to greatly simplify.

	sim: igen: support in-place updates ourself
	Every file that igen outputs is then processed with the move-if-changed
	shell script.  This creates a lot of boilerplate in the build and not an
	insignificant amount of build-time overhead.  Move the simple "is the file
	changed" logic into igen itself.

	sim: igen: constify itable data structures
	These are const data arrays of strings and numbers.  We don't want
	or need them to be writable, so mark them all const.

	      gdb/testsuite: new test for recent dwarf reader issue

	A new test (gdb.base/signed-builtin-types.exp) was added that made use
	of 'info sources' to figure out if the debug information for a
	particular object file had been fully expanded or not.  Unfortunately
	some lines of the 'info sources' output can be very long, this was
	observed on some systems where the debug information for the
	dynamic-linker was installed, in this case, the list of source files
	associated with the dynamic linker was so long it would cause expect's
	internal buffer to overflow.

	This commit switches from using 'info sources' to 'maint print
	objfile', the output from the latter command is more compact, but
	also, can be restricted to a single named object file.

	With this change in place I am no longer seeing buffer overflow errors
	from expect when running gdb.base/signed-builtin-types.exp.

	RISC-V: Reorder the prefixed extensions which are out of order.

	In the past we only allow to reorder the prefixed extensions.  But according
	to the PR 14 in the riscv-toolchain-convention, we can also relax the order
	checking to allow the whole extensions be written out of orders, including
	the single standard extensions and the prefixed multi-letter extensions.
	Just that we still need to follow the following rules as usual,

	1. prefixed extensions need to be seperated with `_'.
	2. prefixed extensions need complete <major>.<minor> version if set.

	Please see the details in the march-ok-reorder gas testcase.

	Passed the riscv-gnu-toolchain regressions.

	sim: switch sim_{read,write} APIs to 64-bit all the time [PR sim/7504]
	We've been using SIM_ADDR which has always been 32-bit.  This means
	the upper 32-bit address range in 64-bit sims is inaccessible.  Use
	64-bit addresses all the time since we want the APIs to be stable
	regardless of the active arch backend (which can be 32 or 64-bit).

	The length is also 64-bit because it's completely feasible to have
	a program that is larger than 4 GiB in size/image/runtime.  Forcing
	the caller to manually chunk those accesses up into 4 GiB at a time
	doesn't seem useful to anyone.

	sframe.h: add support for .cfi_b_key_frame
	ARM 8.3 provides five separate keys that can be used to authenticate

	  };

	Analogous to the above, in SFrame format V1, a bit is reserved in the SFrame
	FDE to indicate which key is used for signing the frame's return addresses:
	  - SFRAME_AARCH64_PAUTH_KEY_A has a value of 0
	  - SFRAME_AARCH64_PAUTH_KEY_B has a value of 1

	x86: correct dependencies of a few AVX512 sub-features
	Like AVX512-FP16, several other extensions require wider than 16-bit
	mask registers. As a result they take AVX512BW as a prereq, not (just)
	AVX512F. Which in turn points out wrong expectations in the noavx512-1
	testcase.

	x86: rework noavx512-1 testcase
	So far the set of ".noavx512*" has been accumulating, which isn't ideal.
	In particular this hides issues with dependencies between features.
	Switch back to the default ISA before disabling a particular subset.
	Furthermore limit redundancy by wrapping the repeated block of insns in
	an .irp.

	x86: add dependencies on AVX2
	Like AVX-VNNI both VAES and VPCLMUL take AVX2 as a prereq, for operating
	on up to 256-bit packed integer vectors.

	x86: correct SSE dependencies
	SSE itself takes FXSR as a prereq. Like AES, PCLMUL, and SHA both GFNI
	and KL take SSE2 as a prereq, for operating on packed integers. And
	while correcting KL also record it as a prereq to WIDEKL.

2022-12-22  Jan Beulich  <jbeulich@suse.com>

	x86: correct what gets disabled by certain ".arch .no*"
	Features with prereqs as well as features with dependents cannot re-use
	CPU_*_MASK for the 3rd argument of SUBARCH() - they need to use
	CPU_ANY_*_MASK in order to avoid disabling too many (when there are
	prereqs) and/or too few (when there are dependents) features.

	Generally any CPU_ANY_*_MASK which exist should not remain unused.
	Exceptions are
	- FISTTP which has no corresponding entry in cpu_arch[],
	- IAMCU which is a base architecture and hence uses ARCH(), not
	  SUBARCH() (only extensions can be disabled, but unlike for Cpu*86 it
	  would be a little more clumsy to suppress generating of the #define).

2022-12-22  Jan Beulich  <jbeulich@suse.com>

	x86: re-work ISA extension dependency handling
	Getting both forward and reverse ISA dependencies right / consistent has
	been a permanent source of mistakes. Reduce what needs specifying
	manually to just the direct forward dependencies. Transitive forward
	dependencies as well as reverse ones are now derived and hence cannot go
	out of sync anymore (at least in the vast majority of cases; there are a
	few special cases to still take care of manually). In the course of this
	several CPU_ANY_*_FLAGS disappear, requiring adjustment to the
	assembler's cpu_arch[].

	Note that to retain the correct reverse dependency of AVX512F wrt
	AVX512-VP2INTERSECT, the latter has the previously missing AVX512F
	prereq added.

	Note further that to avoid adding the following undue prereqs:
	* ATHLON, K8, and AMDFAM10 gain CMOV and FXSR,
	* IAMCU gains 387,
	auxiliary table entries (including a colon-separated modifier) are
	introduced in addition to the ones representing from converting the old
	table.

	To maintain forward-only dependencies between AVX (XOP) and SSE* (SSE4a)
	(i.e. "nosse" not disabling AVX), reverse dependency tracking is
	artifically suppressed.

	As a side effect disabling of SSE or SSE2 will now also disable AES,
	PCLMUL, and SHA (respective elements were missing from
	CPU_ANY_SSE2_FLAGS).

	sim: mips: match target on cpu settings
	We don't need to enforce larger target settings when the only thing

	target matches to only check the CPU.

	sim: mips: move fpu bitsize defines to top-level configure
	This drops support for the --enable-sim-float configure option,
	but it's not clear anyone ever actually used that.  Eventually
	we'll want this to be a runtime option anyways.

	sim: mips: move bitsize defines to top-level configure
	Since the msb value is always defined as the wordsize-1, stop
	hardcoding that value directly, and use a CPP value instead.

	sim: mips: move subtarget defines to top-level configure
	We want to kill off mips/configure entirely.  Move this small part

	sim: mips: always resolve active bfd mach dynamically
	Don't assume that the default bfd that we configured for is the one
	that is always active when running a program.  We already have access
	to the real runtime value, so use it directly.  This simplifies the
	code quite a bit, and will make it easier to support multiple mach's
	in a single binary.

	sim: hw-config.h: move generation to top-level
	In order to compile arch objects from the top-level, we need to
	generate the hw-config.h header, so move that logic up to the top
	level first.

	sim: build: hoist lists of hw devices up
	We need these in the top-level to generate libsim.a, but also in the
	subdirs to generate hw-config.h.  Move it to the local.mk, and pass
	it down when running recursive make.  This avoids duplication, and
	makes it available to both.  We can simplify this once we move the
	various steps up to the top-level too.

	sim: build: hoist lists of common objects up
	In order to create libsim.a in the common dir, we need the list of
	objects for each target.  To avoid duplicating the list with the
	recursive make in each port, pass it down as a variable.  This is
	a temporary hack until the top-level creates libsim.a for ports.

	Use toplevel configure for GMP and MPFR for gdb
	This patch uses the toplevel configure parts for GMP/MPFR for
	gdb. The only thing is that gdb now requires MPFR for building.
	Before it was a recommended but not required library.
	Also this allows building of GMP and MPFR with the toplevel
	directory just like how it is done for GCC.
	We now error out in the toplevel configure of the version
	of GMP and MPFR that is wrong.

	OK after GDB 13 branches? Build gdb 3 ways:
	with GMP and MPFR in the toplevel (static library used at that point for both)
	With only MPFR in the toplevel (GMP distro library used and MPFR built from source)
	With neither GMP and MPFR in the toplevel (distro libraries used)

	Changes from v1:
	* Updated gdb/README and gdb/doc/gdb.texinfo.
	* Regenerated using unmodified autoconf-2.69

	gdb/c++: validate 'using' directives based on the current line
	When asking GDB to print a variable from an imported namespace, we only
	want to see variables imported in lines that the inferior has already
	gone through, as is being tested last in gdb.cp/nsusing.exp. However
	with the proposed change to gdb.cp/nsusing.exp, we get the following
	failures:

	(gdb) PASS: gdb.cp/nsusing.exp: continue to breakpoint: marker10 stop
	print x
	$9 = 911
	(gdb) FAIL: gdb.cp/nsusing.exp: print x, before using statement
	next
	15        y += x;
	(gdb) PASS: gdb.cp/nsusing.exp: using namespace M
	print x
	$10 = 911
	(gdb) PASS: gdb.cp/nsusing.exp: print x, only using M

	Showing that the feature wasn't functioning properly, it just so
	happened that gcc ordered the namespaces in a convenient way.
	This happens because GDB doesn't take into account the line where the
	"using namespace" directive is written. So long as it shows up in the
	current scope, we assume it is valid.

	To fix this, add a new member to struct using_direct, that stores the
	line where the directive was written, and a new function that informs if
	the using directive is valid already.

	Unfortunately, due to a GCC bug, the failure still shows up. Compilers
	that set the declaration line of the using directive correctly (such as
	Clang) do not show such a bug, so the test includes an XFAIL for gcc
	code.

	Finally, because the final test of gdb.cp/nsusing.exp has turned into
	multiple that all would need XFAILs for older GCCs (<= 4.3), and that
	GCC is very old, if it is detected, the test just exits early.

	sim: sim_cpu: invert sim_cpu storage
	Currently all ports have to declare sim_cpu themselves in their
	sim-main.h and then embed the common sim_cpu_base in it.  This
	dynamic makes it impossible to share common object code among
	multiple ports because the core data structure is always different.

	Let's invert this relationship: common code declares sim_cpu, and
	the port uses the new arch_data field for its per-cpu state.

	This is the first in a series of changes: it adds a define to select
	between the old & new layouts, then converts all the ports that don't
	need custom state over to the new layout.  This includes mn10300 that,
	while it defines custom fields in its cpu struct, never uses them.

	sim: ppc: move spreg.[ch] files to the source tree
	Simplify the build by moving the generation of these files from
	build-time (via dgen.c that we have to compile & execute on the
	build system) to maintainer/release mode (via spreg-gen.py that
	we only ever execute when the spreg table actually changes).  It
	speeds up the build process and makes it easier for us to reason
	about & review changes to the code generator.

	The tool is renamed from "dgen" because it's hardcoded to only
	generated spreg files.  It isn't a generalized tool for creating
	lookup tables.

	sim: dv-core: add hw_detach_address method [PR sim/25211]
	The core device has an attach address method as the root of the tree
	which calls out to the sim API.  But it doesn't have a corresponding
	detach method which means we just crash if anything tries to detach
	itself from the core.  In practice, the m68hc11 is the only model
	that actually tries to detach itself on the fly, so no one noticed
	earlier.

	With this in place, we can delete the existing detach code from the
	m68hc11 model since it defaults to "passthru" callback which will in
	turn call the dv-core detach, and they have the same behavior -- call
	the sim core API to detach from the address space.

	gprofng/testsuite: skip Java test without JDK
	There's no point in even trying the Java test when gprofng was built
	without Java support, and when the building of the constituents of the
	testcase also would fail. On such systems this converts the respective
	tests from "unresolved" to "unsupported", making the overall testsuite
	run no longer report failure just because of this.

	gprofng/testsuite: eliminate bogus casts
	Casting pointers to unsigned int is generally problematic and hence
	compilers tend to warn about such. While here they're used only in
	fprintf(), it still seems better to omit such casts, even if only to
	avoid setting bad precedents.

	gprofng/testsuite: correct line continuation in endcases.c
	A backslash used to indicate line continuation (in a macro definition
	here) is not supposed to be followed by blanks or other white space; the
	end-of-line indicator is to follow immediately.

	gprofng/testsuite: correct names for signal handling tests
	The signal handling tests spend most of their time in the signal
	handlers, and hence for profile output to match anything in program
	output, the respective name fields need to hold the handler function
	names. This converts both respective tests from "unresolved" to actually
	succeeding.

	gprofng/testsuite: adjust linking of synprog
	In order for so_syn.so and so_syx.so to be able to access the main
	program's "testtime" variable, that variable needs exposing in the
	dynamic symbol table. Since this is a test program only, do it the brute
	force way and simply expose all global symbols.

	Arm: break gas dependency on libopcodes
	gas doesn't use anything from libopcodes (anymore?) - suppress linking

	Re: The problem with warning in elf_object_p
	Commit 5aa0f10c424e added a per_xvec_warn array to provide support for
	warnings from elf_object_p (and a later patch for warnings from
	pe_bfd_object_p) to be cached and then only printed if the target
	matches.  It was quite limited in the style of message supported, only
	one message could be printed, and didn't really meet the stated aim of
	only warning when a target matches:  There are many other errors and
	warnings that can be emitted by functions called from elf_object_p.

	So this patch extends the error handler functions to support printing
	to a string buffer, extends per_xvec_warn to support multiple errors/
	warnings, and hooks this all into bfd_check_format_matches.  If
	bfd_check_format_matches succeeds then any errors/warnings are printed
	for the matching target.  If bfd_check_format_matches fails either due
	to no match or to multiple matches and only one target vector produced
	errors, then those errors are printed.

	Delay checking whether /proc/pid/mem is writable (PR gdb/29907)
	As of 1bcb0708f229 ("gdb/linux-nat: Check whether /proc/pid/mem is
	writable"), GDB checks if /proc/pid/mem is writable.  This is done
	early at GDB startup, in order to get a consistent warning, instead of
	a warning that depends on whenever GDB writes to inferior memory.

	PR gdb/29907 points out that some build systems (like QEMU's,
	apparently) may call 'gdb --version' to check GDB's presence & its
	version on the system, and that Gentoo's build process has sandboxing
	which blocks the /proc/pid/mem access and thus GDB warns, which
	results in build fails.

	To help with that, this patch delays the /proc/pid/mem check until we
	start or attach to an inferior.  Ends up potentially emiting a warning
	close where we already emit other ptrace- and /proc- related warnings,
	which just Feels Right.

	gdb: fix crash when getting the value of a label symbol
	When the source program contains a goto label, it turns out it's
	actually pretty hard for a user to find out more about that label.
	For example:

	  (gdb) p some_label
	  No symbol "some_label" in current context.
	  (gdb) disassemble some_label
	  No symbol "some_label" in current context.
	  (gdb) x/10i some_label
	  No symbol "some_label" in current context.
	  (gdb) break some_label
	  Breakpoint 2 at 0x401135: file /tmp/py-label-symbol-value.c, line 35.

	In all cases, some_label is a goto label within the current frame.
	Only placing a breakpoint on the label worked.

	This all seems a little strange to me, it feels like asking about a
	goto label would not be an unreasonable thing for a user to do.

	This commit doesn't fix any of the above issues, I mention them just
	to provide a little context for why the following issue has probably
	not been seen before.

	It turns out there is one way a user can access the symbol for a goto
	label, through the Python API:

	  python frame = gdb.selected_frame()
	  python frame_pc = frame.pc()
	  python block = gdb.current_progspace().block_for_pc(frame_pc)
	  python symbol,_ = gdb.lookup_symbol('some_label', block, gdb.SYMBOL_LABEL_DOMAIN)
	  python print(str(symbol.value()))
	  ../../src/gdb/findvar.c:204: internal-error: store_typed_address: Assertion `type->is_pointer_or_reference ()' failed.

	The problem is that label symbols are created using the
	builtin_core_addr type, which is a pure integer type.

	When GDB tries to fetch the value of a label symbol then we end up in
	findvar.c, in the function language_defn::read_var_value, in the
	LOC_LABEL case.  From here store_typed_address is called to store the
	address of the label into a value object with builtin_core_addr type.

	The problem is that store_typed_address requires that the destination
	type be a pointer or reference, which the builtin_core_addr type is
	not.

	Now it's not clear what type a goto label address should have, but
	GCC has an extension that allows users to take the address of a goto
	label (using &&), in that case the result is of type 'void *'.

	I propose that when we convert the CORE_ADDR value to a GDB value
	object, we use builtin_func_ptr type instead of builtin_core_addr,
	this means the result will be of type 'void (*) ()'.  The benefit of
	this approach is that when gdbarch_address_to_pointer is called the
	target type will be correctly identified as a pointer to code, which
	should mean any architecture specific adjustments are done correctly.

	We can then cast the new value to 'void *' type with a call to
	value_cast_pointer, this should not change the values bit
	representation, but will just update the type.

	After this asking for the value of a label symbol works just fine:

	  (gdb) python print(str(symbol.value()))
	  0x401135 <main+35>

	And the type is maybe what we'd expect:

	  (gdb) python print(str(symbol.value().type))
	  void *

	[aarch64] Fix removal of non-address bits for PAuth
	PR gdb/28947

	The address_significant gdbarch setting was introduced as a way to remove
	non-address bits from pointers, and it is specified by a constant.  This
	constant represents the number of address bits in a pointer.

	Right now AArch64 is the only architecture that uses it, and 56 was a
	correct option so far.

	But if we are using Pointer Authentication (PAuth), we might use up to 2 bytes
	from the address space to store the required information.  We could also have
	cases where we're using both PAuth and MTE.

	We could adjust the constant to 48 to cover those cases, but this doesn't
	cover the case where GDB needs to sign-extend kernel addresses after removal
	of the non-address bits.

	This has worked so far because bit 55 is used to select between kernel-space
	and user-space addresses.  But trying to clear a range of bits crossing the
	bit 55 boundary requires the hook to be smarter.

	The following patch renames the gdbarch hook from significant_addr_bit to
	remove_non_address_bits and passes a pointer as opposed to the number of
	bits.  The hook is now responsible for removing the required non-address bits
	and sign-extending the address if needed.

	While at it, make GDB and GDBServer share some more code for aarch64 and add a
	new arch-specific testcase gdb.arch/aarch64-non-address-bits.exp.

	gdb: remove static buffer in command_line_input
	[I sent this earlier today, but I don't see it in the archives.
	Resending it through a different computer / SMTP.]

	The use of the static buffer in command_line_input is becoming
	problematic, as explained here [1].  In short, with this patch [2] that
	attempt to fix a post-hook bug, when running gdb.base/commands.exp, we
	hit a case where we read a "define" command line from a script file
	using command_command_line_input.  The command line is stored in
	command_line_input's static buffer.  Inside the define command's
	execution, we read the lines inside the define using command_line_input,
	which overwrites the define command, in command_line_input's static
	buffer.  After the execution of the define command, execute_command does
	a command look up to see if a post-hook is registered.  For that, it
	uses a now stale pointer that used to point to the define command, in
	the static buffer, causing a use-after-free.  Note that the pointer in
	execute_command points to the dynamically-allocated buffer help by the
	static buffer in command_line_input, not to the static object itself,
	hence why we see a use-after-free.

	Fix that by removing the static buffer.  I initially changed
	command_line_input and other related functions to return an std::string,
	which is the obvious but naive solution.  The thing is that some callees
	don't need to return an allocated string, so this this an unnecessary
	pessimization.  I changed it to passing in a reference to an std::string
	buffer, which the callee can use if it needs to return
	dynamically-allocated content.  It fills the buffer and returns a
	pointers to the C string inside.  The callees that don't need to return
	dynamically-allocated content simply don't use it.

	So, it started with modifying command_line_input as described above, all
	the other changes derive directly from that.

	One slightly shady thing is in handle_line_of_input, where we now pass a
	pointer to an std::string's internal buffer to readline's history_value
	function, which takes a `char *`.  I'm pretty sure that this function
	does not modify the input string, because I was able to change it (with
	enough massaging) to take a `const char *`.

	A subtle change is that we now clear a UI's line buffer using a
	SCOPE_EXIT in command_line_handler, after executing the command.
	This was previously done by this line in handle_line_of_input:

	  /* We have a complete command line now.  Prepare for the next
	     command, but leave ownership of memory to the buffer .  */
	  cmd_line_buffer->used_size = 0;

	I think the new way is clearer.

	libsframe asan: avoid generating misaligned loads
	There are two places where unaligned loads were seen on aarch64:
	  - #1. access to the SFrame FRE stack offsets in the in-memory
	    representation/abstraction provided by libsframe.
	  - #2. access to the SFrame FRE start address in the on-disk representation
	    of the frame row entry.

	For #1, we can fix this by reordering the struct members of
	sframe_frame_row_entry in libsframe/sframe-api.h.

	For #2, we need to default to using memcpy instead, and copy out the bytes
	to a location for output.

	SFrame format is an unaligned on-disk format. As such, there are other blobs
	of memory in the on-disk SFrame FRE that are on not on their natural
	boundaries.  But that does not pose further problems yet, because the users
	are provided access to the on-disk SFrame FRE data via libsframe's
	sframe_frame_row_entry, the latter has its' struct members aligned on their
	respective natural boundaries (and initialized using memcpy).

	gdb: use gdb_assert not internal_error
	Spotted a couple of places in findvar.c where we use:

	    internal_error ("...");

	this commit changes these to be:

	  gdb_assert ( CONDITION );

	which I think is better.

	Unless we happen to hit the internal_error calls (which was bad) there

	gdb: ensure all targets are popped before an inferior is destructed
	Now that the inferiors target_stack automatically manages target
	reference counts, we might think that we don't need to unpush targets
	when an inferior is deleted...

	...unfortunately that is not the case.  The inferior::unpush function
	can do some work depending on the type of target, so it is important
	that we still pass through this function.

	To ensure that this is the case, in this commit I've added an assert
	to inferior::~inferior that ensures the inferior's target_stack is
	empty (except for the ever present dummy_target).

	I've then added a pop_all_targets call to delete_inferior, otherwise
	the new assert will fire in, e.g. the gdb.python/py-inferior.exp test.

	gdb: remove the pop_all_targets (and friends) global functions
	This commit removes the global functions pop_all_targets,
	pop_all_targets_above, and pop_all_targets_at_and_above, and makes
	them methods on the inferior class.

	As the pop_all_targets functions will unpush each target, which
	decrements the targets reference count, it is possible that the target
	might be closed.

	Right now, closing a target, in some cases, depends on the current
	inferior being set correctly, that is, to the inferior from which the
	target was popped.

	To facilitate this I have used switch_to_inferior_no_thread within the
	new methods.  Previously it was the responsibility of the caller to
	ensure that the correct inferior was selected.

	In a couple of places (event-top.c and top.c) I have been able to
	remove a previous switch_to_inferior_no_thread call.

	In remote_unpush_target (remote.c) I have left the
	switch_to_inferior_no_thread call as it is required for the
	generic_mourn_inferior call.

	gdb: remove decref_target
	The decref_target function is not really needed.  Calling

	not just rename decref_target to target_ops::decref?

	That's what this commit does.

	It's not exactly renaming to target_ops::decref, because the decref
	functionality is handled by a policy class, so the new name is now
	target_ops_ref_policy::decref.

	gdb: have target_stack automate reference count handling
	This commit changes the target_stack class from using a C style array
	of 'target_ops *' to using a C++ std::array<target_ops_ref, ...>.  The
	benefit of this change is that some of the reference counting of
	target_ops objects is now done automatically.

	This commit fixes a crash in gdb.python/py-inferior.exp where GDB
	crashes at exit, leaving a core file behind.

	The crash occurs in connpy_connection_dealloc, and is actually
	triggered by this assert:

	gdb_assert (conn_obj->target == nullptr);

	Now a little aside...

	    ... the assert is never actually printed, instead GDB crashes due
	    to calling a pure virtual function.  The backtrace at the point of
	    crash looks like this:

	      #7  0x00007fef7e2cf747 in std::terminate() () from /lib64/libstdc++.so.6
	      #8  0x00007fef7e2d0515 in __cxa_pure_virtual () from /lib64/libstdc++.so.6
	      #9  0x0000000000de334d in target_stack::find_beneath (this=0x4934d78, t=0x2bda270 <the_dummy_target>) at ../../s>
	      #10 0x0000000000df4380 in inferior::find_target_beneath (this=0x4934b50, t=0x2bda270 <the_dummy_target>) at ../.>
	      #11 0x0000000000de2381 in target_ops::beneath (this=0x2bda270 <the_dummy_target>) at ../../src/gdb/target.c:3047
	      #12 0x0000000000de68aa in target_ops::supports_terminal_ours (this=0x2bda270 <the_dummy_target>) at ../../src/gd>
	      #13 0x0000000000dde6b9 in target_supports_terminal_ours () at ../../src/gdb/target.c:1112
	      #14 0x0000000000ee55f1 in internal_vproblem(internal_problem *, const char *, int, const char *, typedef __va_li>

	    Notice in frame #12 we called target_ops::supports_terminal_ours,
	    however, this is the_dummy_target, which is of type dummy_target,
	    and so we should have called dummy_target::supports_terminal_ours.
	    I believe the reason we ended up in the wrong implementation of
	    supports_terminal_ours (which is a virtual function) is because we
	    made the call during GDB's shut-down, and, I suspect, the vtables
	    were in a weird state.

	    Anyway, the point of this patch is not to fix GDB's ability to
	    print an assert during exit, but to address the root cause of the
	    assert.  With that aside out of the way, we can return to the main
	    story...

	Connections are represented in Python with gdb.TargetConnection
	objects (or its sub-classes).  The assert in question confirms that
	when a gdb.TargetConnection is deallocated, the underlying GDB
	connection has itself been removed from GDB.  If this is not true then
	we risk creating multiple different gdb.TargetConnection objects for
	the same connection, which would be bad.

	To ensure that we have one gdb.TargetConnection object for each
	connection, the all_connection_objects map exists, this maps the
	process_stratum_target object (the connection) to the
	gdb.TargetConnection object that represents the connection.

	When a connection is removed in GDB the connection_removed observer
	fires, which we catch with connpy_connection_removed, this function
	then sets conn_obj->target to nullptr, and removes the corresponding
	entry from the all_connection_objects map.

	The first issue here is that connpy_connection_dealloc is being called
	as part of GDB's exit code, which is run after the Python interpreter
	has been shut down.  The connpy_connection_dealloc function is used to
	deallocate the gdb.TargetConnection Python object.  Surely it is
	wrong for us to be deallocating Python objects after the interpreter
	has been shut down.

	The reason why connpy_connection_dealloc is called during GDB's exit
	is that the global all_connection_objects map is still holding a
	reference to the gdb.TargetConnection object.  When the map is
	destroyed during GDB's exit, the gdb.TargetConnection objects within
	the map can finally be deallocated.

	The reason why all_connection_objects has contents when GDB exits, and
	the reason the assert fires, is that, when GDB exits, there are still
	some connections that have not yet been removed from GDB, that is,
	they have a non-zero reference count.

	If we take a look at quit_force (top.c) you can see that, for each
	inferior, we call pop_all_targets before we (later in the function)
	call do_final_cleanups.  It is the do_final_cleanups call that is
	responsible for shutting down the Python interpreter.  The
	pop_all_targets calls should, in theory, cause all the connections to
	be removed from GDB.

	That this isn't working indicates that some targets have a non-zero
	reference count even after this final pop_all_targets call, and
	indeed, when I debug GDB, that is what I see.

	I tracked the problem down to delete_inferior where we do some house
	keeping, and then delete the inferior object, which calls
	inferior::~inferior.

	In neither delete_inferior or inferior::~inferior do we call
	pop_all_targets, and it is this missing call that means we leak some
	references to the target_ops objects on the inferior's target_stack.

	In this commit I will provide a partial fix for the problem.  I say
	partial fix, but this will actually be enough to resolve the crash.
	In a later commit I will provide the final part of the fix.

	As mentioned at the start of the commit message, this commit changes
	the m_stack in target_stack to hold target_ops_ref objects.  This
	means that when inferior::~inferior is called, and m_stack is
	released, we automatically decrement the target_ops reference count.
	With this change in place we no longer leak any references, and now,
	in quit_force the final pop_all_targets calls will release the final
	references.  This means that the targets will be correctly closed at
	this point, which means the connections will be removed from GDB and
	the Python objects deallocated before the Python interpreter shuts
	down.

	There's a slight oddity in target_stack::unpush, where we std::move
	the reference out of m_stack like this:

	  auto ref = std::move (m_stack[stratum]);

	the `ref' isn't used explicitly, but it serves to hold the
	target_ops_ref until the end of the scope while allowing the m_stack
	entry to be reset back to nullptr.  The alternative would be to
	directly set the m_stack entry to nullptr, like this:

	  m_stack[stratum] = nullptr;

	The problem here is that when we set the m_stack entry to nullptr we
	first decrement the target_ops reference count, and then set the array
	entry to nullptr.

	If the decrement means that the target_ops object reaches a zero
	reference count then the target_ops object will be closed by calling
	target_close.  In target_close we ensure that the target being closed
	is not in any inferiors target_stack.

	As we decrement before clearing, then this check in target_close will
	fail, and an assert will trigger.

	By using std::move to move the reference out of m_stack, this clears
	the m_stack entry, meaning the inferior no longer contains the
	target_ops in its target_stack.  Now when the REF object goes out of
	scope and the reference count is decremented, target_close can run
	successfully.

	I've made use of the Python connection_removed listener API to add a
	test for this issue.  The test installs a listener and then causes
	delete_inferior to be called, we can then see that the connection is
	then correctly removed (because the listener triggers).

	gdb/remote: remove some manual reference count handling
	While working on some other target_ops reference count related code, I
	spotted that in remote.c we do some manual reference count handling,
	i.e. we call target_ops::incref and decref_target (which wraps
	target_ops::decref).

	I think it would be better to make use of gdb::ref_ptr to automate the
	reference count management.

	So, this commit updates scoped_mark_target_starting in two ways,
	first, I use gdb::ref_ptr to handle the reference counts.  Then,
	instead of using the scoped_mark_target_starting constructor and
	destructor to set and reset the starting_up flag, I now use a
	scoped_restore_tmpl object to set and restore the flag.

	The above changes mean that the scoped_mark_target_starting destructor
	can be completely removed, and the constructor body is now empty.

	I've also fixed a typo in the class comment.

	The only change in behaviour after this commit is that previously we
	didn't care what the value of starting_up was, we just set it to true
	in the constructor and false in the destructor.

	Now, I assert that the flag is initially false, then set the flag true
	when the scoped_mark_target_starting is created.

	As the starting_up flag is initialized to false then, for the assert
	to fire, we would need to recursively enter
	remote_target::start_remote_1, which I don't think is something we
	should be doing, so I think the new assert is an improvement.

	gdb: add SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT
	After the previous commit converted symbol-lookup debug to use the new
	debug scheme, this commit adds SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT.

	The previous commit didn't add SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT
	because symbol-lookup debug is controlled by an 'unsigned int' rather
	than a 'bool' control variable, we use the numeric value to offer
	different levels of verbosity for symbol-lookup debug.

	The *_SCOPED_DEBUG_ENTER_EXIT mechanism currently relies on capturing
	a reference to the bool control variable, and evaluating the variable
	both on entry, and at exit, this is done in the scoped_debug_start_end
	class (see gdbsupport/common-debug.h).

	This commit templates scoped_debug_start_end so that the class can
	accept either a 'bool &' or an invokable object, e.g. a lambda
	function, or a function pointer.

	The existing scoped_debug_start_end and scoped_debug_enter_exit macros
	in common-debug.h are updated to support scoped_debug_enter_exit being
	templated, however, nothing outside of common-debug.h needs to change.

	I've then added SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT in symtab.h, and
	added a couple of token uses in symtab.c.  I didn't want to add too
	much in this first commit, this is really about updating
	common-debug.h to support this new functionality.

	Within symtab.h I created a couple of global functions that can be
	used to query the status of the symbol_lookup_debug control variable,
	these functions are then used within the two existing macros:

	  symbol_lookup_debug_printf
	  symbol_lookup_debug_printf_v

	and also in the new SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT macro.

	gdb/testsuite: new test for recent dwarf reader issue
	This commit provides a test for this commit:

	  commit 55fc1623f942fba10362cb199f9356d75ca5835b
	  Date:   Thu Nov 3 13:49:17 2022 -0600

	      Add name canonicalization for C

	Which resolves PR gdb/29105.  My reason for writing this test was a
	desire to better understand the above commit, my process was to study
	the commit until I thought I understood it, then write a test to
	expose the issue.  As the original commit didn't have a test, I
	thought it wouldn't hurt to commit this upstream.

	The problem tested for here is already described in the above commit,
	but I'll give a brief description here.  This description describes
	GDB prior to the above commit:

	  - Builtin types are added to GDB using their canonical name,
	    e.g. "short", not "signed short",

	  - When the user does something like 'p sizeof(short)', then this is
	    handled in c-exp.y, and results in a call to lookup_signed_type
	    for the name "int".  The "int" here is actually being looked up as
	    the type for the result of the 'sizeof' expression,

	  - In lookup_signed_type GDB first adds a 'signed' and looks for that
	    type, so in this case 'signed int', and, if that lookup fails, GDB
	    then looks up 'int',

	  - The problem is that 'signed int' is not the canonical name for a
	    signed int, so no builtin type with that name will be found, GDB
	    will then go to each object file in turn looking for a matching
	    type,

	  - When checking each object file, GDB will first check the partial
	    symtab to see if the full symtab should be expanded or not.
	    Remember, at this point GDB is looking for 'signed int', there
	    will be no partial symbols with that name, so GDB will not expand
	    anything,

	  - However, GDB checks each partial symbol using multiple languages,
	    not just the current language (C in this case), so, when GDB
	    checks using the C++ language, the symbol name is first
	    canonicalized (the code that does this can be found
	    lookup_name_info::language_lookup_name).  As the canonical form of
	    'signed int' is just 'int', GDB then looks for any symbols with
	    the name 'int', most partial symtabs will contain such a symbol,
	    so GDB ends up expanding pretty much every symtab.

	The above commit fixes this by avoiding the use of non-canonical names
	with C, now the initial builtin type lookup will succeed, and GDB
	never even considers whether to expand any additional symtabs.

	The test case creates a library that includes char, short, int, and
	long types, and a test program that links against the library.

	In the test script we start the inferior, but don't allow it to
	progress far enough that the debug information for the library has
	been fully expanded yet.

	Then we evaluate some 'sizeof(TYPE)' expressions.

	In the buggy version of GDB this would cause the debug information
	for the library to be fully expanded, while in the fixed version of
	GDB this will not be the case.

	We use 'info sources' to determine if the debug information has been
	fully expanded or not.

	gdb/testsuite: fix readnow detection
	The following commit broke the readnow detection in the testsuite:

	  commit dfaa040b440084dd73ebd359326752d5f44fc02c
	  Date:   Mon Mar 29 18:31:31 2021 -0600

	      Remove some "OBJF_READNOW" code from dwarf2_debug_names_index

	The testsuite checks if GDB was started with the -readnow flag by
	using the 'maintenance print objfiles' command, and looking for the
	string 'faked for "readnow"' in the output.  This is implemented in
	two helper procs `readnow` (gdb.exp) and `mi_readnow` (mi-support.exp).

	The following tests all currently depend on this detection:

	  gdb.base/maint.exp
	  gdb.cp/nsalias.exp
	  gdb.dwarf2/debug-aranges-duplicate-offset-warning.exp
	  gdb.dwarf2/dw2-stack-boundary.exp
	  gdb.dwarf2/dw2-zero-range.exp
	  gdb.dwarf2/gdb-index-nodebug.exp
	  gdb.mi/mi-info-sources.exp
	  gdb.python/py-symbol.exp
	  gdb.rust/traits.exp

	The following test also includes detection of 'readnow', but does the
	detection itself by checking $::GDBFLAGS for the readnow flag:

	  gdb.opt/break-on-_exit.exp

	The above commit removed from GDB the code that produced the 'faked
	for "readnow"' string, as a consequence the testsuite can no longer
	correctly spot when readnow is in use, and many of the above tests
	will fail (at least partially).

	When looking at the above tests, I noticed that gdb.rust/traits.exp
	does call `readnow`, but doesn't actually use the result, so I've
	removed the readnow call, this simplifies the next part of this patch
	as gdb.rust/traits.exp was the only place an extra regexp was passed
	to the readnow call.

	Next I have rewritten `readnow` to check the $GDBFLAGS for the
	-readnow flag, and removed the `maintenance print objfiles` check.  At
	least for all the tests above, when using the readnow board, this is
	good enough to get everything passing again.

	For the `mi_readnow` proc, I changed this to just call `readnow` from
	gdb.exp, I left the mi_readnow name in place - in the future it might
	be the case that we want to do some different checks here.

	Finally, I updated gdb.opt/break-on-_exit.exp to call the `readnow`
	proc.

	With these changes, all of the tests listed above now pass correctly
	when using the readnow board.

	RISC-V: Add string length check for operands in AS
	The current AS accepts invalid operands due to miss of operands length check.
	For example, "e6" is an invalid operand in (vsetvli a0, a1, e6, mf8, tu, ma),
	but it's still accepted by assembler.  In detail, the condition check "strncmp
	(array[i], *s, len) == 0" in arg_lookup function passes with "strncmp ("e64",
	"e6", 2)" in the case above.  So the generated encoding is same as that of
	(vsetvli a0, a1, e64, mf8, tu, ma).

	This patch fixes issue above by prompting an error in such case and also adds
	a new testcase.

2022-12-13  Tom Tromey  <tromey@adacore.com>

	Fix control-c handling on Windows
	As Hannes pointed out, the Windows target-async patches broke C-c
	handling there.  Looking into this, I found a few oddities, fixed
	here.

	First, windows_nat_target::interrupt calls GenerateConsoleCtrlEvent.
	I think this event can be ignored by the inferior, so it's not a great
	way to interrupt.  Instead, using DebugBreakProcess (or a more
	complicated thing for Wow64) seems better.

	Second, windows_nat_target did not implement the pass_ctrlc method.
	Implementing this lets us remove the special code to call
	SetConsoleCtrlHandler and instead integrate into gdb's approach to C-c
	handling.  I believe that this should also fix the race that's
	described in the comment that's being removed.

	Initially, I thought a simpler version of this patch would work.
	However, I think what happens is that some other library (I'm not sure
	what) calls SetConsoleCtrlHandler while gdb is running, and this
	intercepts and handles C-c -- so that the gdb SIGINT handler is not
	called.  C-break continues to work, presumably because whatever
	handler is installed ignores it.

	This patch works around this issue by ensuring that the gdb handler
	always comes first.

	Refactor code to check for terminal sharing
	This refactors the code to check for terminal sharing.
	is_gdb_terminal is exported, and sharing_input_terminal_1 is renamed,
	slightly refactored, and moved to posix-hdep.c.  A new
	Windows-specific implementation of this function is added to
	mingw-hdep.c.

	MSDN has a warning about GetConsoleProcessList

	    This API is not recommended and does not have a virtual terminal
	    equivalent. [...] Applications remoting via cross-platform
	    utilities and transports like SSH may not work as expected if
	    using this API.

	However, we believe this isn't likely to be an issue for gdb.

	[gdb/tdep] Fix s390_linux_nat_target::stopped_by_watchpoint
	On s390x-linux, I run into:
	...
	(gdb) continue^M
	Continuing.^M
	breakpoint.c:5784: internal-error: bpstat_stop_status_nowatch: \
	  Assertion `!target_stopped_by_watchpoint ()' failed.^M
	A problem internal to GDB has been detected,^M
	further debugging may prove unreliable.^M
	FAIL: gdb.threads/watchpoint-fork.exp: parent: singlethreaded: \
	  breakpoint after the first fork (GDB internal error)
	...

	What happens is the follow:
	- a watchpoint event triggers
	- the event is processed, s390_linux_nat_target::stopped_by_watchpoint is called and
	  it returns true, as expected
	- the watchpoint event is reported by gdb, and gdb stops
	- we issue a continue command
	- a fork event triggers
	- the event is processed, and during processing that event
	  s390_linux_nat_target::stopped_by_watchpoint is called again, and returns
	  true
	- the assertion fails, because the function is expected to return false

	The function s390_linux_nat_target::stopped_by_watchpoint returns true the
	second time, because it looks at the exact same data that was looked at when
	it was called the first time, and that data hasn't changed.

	There's code in the same function that intends to prevent that from happening:
	...
	      /* Do not report this watchpoint again.  */
	      memset (&per_lowcore, 0, sizeof (per_lowcore));
	      if (ptrace (PTRACE_POKEUSR_AREA, s390_inferior_tid (), &parea, 0) < 0)
	       perror_with_name (_("Couldn't clear watchpoint status"));
	...
	and that probably used to work for older kernels, but no longer does since
	linux kernel commit 5e9a26928f55 ("[S390] ptrace cleanup").

	Fix this by copying this:
	...
	  siginfo_t siginfo;
	  if (!linux_nat_get_siginfo (inferior_ptid, &siginfo))
	    return false;
	  if (siginfo.si_signo != SIGTRAP
	      || (siginfo.si_code & 0xffff) != TRAP_HWBKPT)
	    return false;
	...
	from aarch64_linux_nat_target::stopped_data_address and remove the
	obsolete watchpoint status clearing code.

	Tested on s390x-linux.

	gas: re-work line number tracking for macros and their expansions
	The PR gas/16908 workaround aimed at uniformly reporting line numbers
	to reference macro invocation sites. As mentioned in a comment this may
	be desirable for small macros, but often isn't for larger ones. As a
	first step improve diagnostics to report both locations, while aiming at
	leaving generated debug info unaltered.

	Note that macro invocation context is lost for any diagnostics issued
	only after all input was processed (or more generally for any use of
	as_*_where(), as the functions can't know whether the passed in location
	is related to [part of] the present stack of locations). To maintain the
	intended workaround behavior for PR gas/16908, a new as_where() is
	introduced to "look through" macro invocations, while the existing
	as_where() is renamed (and used in only very few places for now). Down
	the road as_where() will likely want to return a list of (file,line)
	pairs.

	gdb: fix possible use-after-free when executing commands
	In principle, `execute_command()` does following:

	   struct cmd_list_element *c;
	   c = lookup_cmd ( ... );
	   ...
	   /* If this command has been pre-hooked, run the hook first.  */
	   execute_cmd_pre_hook (c);
	   ...
	   /* ...execute the command `c` ...*/
	   ...
	   execute_cmd_post_hook (c);

	This may lead into use-after-free error.  Imagine the command
	being executed is a user-defined Python command that redefines
	itself.  In that case, struct `cmd_list_element` pointed to by
	`c` is deallocated during its execution so it is no longer valid
	when post hook is executed.

	To fix this case, this commit looks up the command once again
	after it is executed to get pointer to (possibly newly allocated)
	`cmd_list_element`.

	x86: further re-work insn/suffix recognition to also cover MOVSX
	PR gas/29524

	Having templates with a suffix explicitly present has always been
	quirky. After prior adjustment all that's left to also eliminate the
	anomaly from move-with-sign-extend is to consolidate the insn templates
	and to make may_need_pass2() cope (plus extend testsuite coverage).

	x86: drop (now) stray IsString
	The need for them on the operand-less string insns has gone away with
	the removal of maybe_adjust_templates() and associated logic. Since
	i386_index_check() needs adjustment then anyway, take the opportunity
	and also simplify it, possible again as a result of said removal (plus
	the opcode template adjustments done here).

	x86: move bad-use-of-TLS-reloc check
	Having it in match_template() is unhelpful. Neither does looking for the
	next template to possibly match make any sense in that case, nor is the
	resulting diagnostic making clear what the problem is.

	While moving the check, also generalize it to include all SIMD and VEX-
	encoded insns. This way an existing conditional can be re-used in
	md_assemble(). Note though that this still leaves a lof of insns which
	are also wrong to use with these relocations.

	Further fold the remaining check (BFD_RELOC_386_GOT32) with the XRELEASE
	related one a few lines down. This again allows re-using an existing
	conditional.

	x86-64: allow HLE store of accumulator to absolute 32-bit address
	In commit 1212781b35c9 ("ix86: allow HLE store of accumulator to
	absolute address") I was wrong to exclude 64-bit code. Dropping the
	check also leads to better diagnostics in 64-bit code ("MOV", after
	all, isn't invalid with "XRELEASE").

	While there also limit the amount of further checks done: The operand
	type checks that were there were effectively redundant with other ones
	anyway, plus it's quite fine to also have "xrelease mov <disp>, %eax"
	look for the next MOV template (in fact again also improving
	diagnostics).

	ix86: don't recognize/derive Q suffix in the common case
	Have its use, except where actually legitimate, result in the same "only
	supported in 64-bit mode" diagnostic as emitted for other 64-bit only
	insns. Also suppress deriving of the suffix in Intel mode except in the
	legitimate cases. This in exchange allows dropping the respective code
	from match_template().

	To maintain reasonable diagnostics (in particular to avoid "`mov' is
	only supported in 64-bit mode" on the SIMD forms of MOVQ) we need to
	defer parse_insn()'s emitting of errors unrelated to prefix parsing.
	Utilize i.error just like match_template() does.

	Oddly enough despite gcc's preference towards FILDQ and FIST{,T}Q we
	had no testcase whatsoever for these. Therefore such tests are being
	added. Note that the removed line in the x86-64-lfence-load testcase
	was redundant with the exact same one a few lines up.

2022-12-12  Jan Beulich  <jbeulich@suse.com>

	x86: re-work insn/suffix recognition
	Having templates with a suffix explicitly present has always been
	quirky. Introduce a 2nd matching pass in case the 1st one couldn't find
	a suitable template _and_ didn't itself already need to trim off a
	suffix to find a match at all. This requires error reporting adjustments
	(albeit luckily fewer than I was afraid might be necessary), as errors
	previously reported during matching now need deferring until after the
	2nd pass (because, obviously, we must not emit any error if the 2nd pass
	succeeds). While also related to PR gas/29524, it was requested that
	move-with-sign-extend be left as broken as it always was.

	PR gas/29525
	Note that with the dropped CMPSD and MOVSD Intel Syntax string insn
	templates taking operands, mixed IsString/non-IsString template groups
	(with memory operands) cannot occur anymore. With that
	maybe_adjust_templates() becomes unnecessary (and is hence being
	removed).

	PR gas/29526
	Note further that while the additions to the intel16 testcase aren't
	really proper Intel syntax, we've been permitting all of those except
	for the MOVD variant. The test therefore is to avoid re-introducing such
	an inconsistency.

	gas/codeview: avoid "shadowing" of glibc function name
	While not "index" this time, old enough glibc also has an (unguarded)
	declaration of fileno() in stdio.h, which triggers a "shadows a global
	declaration" warning with our choice of warning level and with at least
	some gcc versions.

	x86: generate template sets data at build time
	Speed up gas startup by avoiding runtime allocation of the instances of
	type "templates". At the same time cut the memory requirement to just
	very little over half (not even accounting for any overhead
	notes_alloc() may incur) by reusing the "end" slot of a preceding entry
	for the "start" slot of the subsequent one.

	x86: drop sentinel from i386_optab[]
	Now that the table is local to gas, ARRAY_SIZE() can be used to
	determine the end of the table. Re-arrange the processing loop in
	md_begin() accordingly, at the same time folding the two calls to
	notes_alloc() into just one.

	x86: add generated tables dependency check to gas
	As requested by H.J., just for the sake of people potentially building

	warning, but I can see how this may not be easily noticable among other
	make output (depending in particular on the verbosity level).

	gas doesn't use anything from libopcodes anymore - suppress linking in

	x86: remove i386-opc.c
	Remove the now empty i386-opc.c. To compensate, tie table generation in
	opcodes/ to the building of i386-dis.o, despite the file not really

	x86: instantiate i386_{op,reg}tab[] in gas instead of in libopcodes
	Unlike many other architectures, x86 does not share an opcode table
	between assembly and disassembly. Any consumer of libopcodes would only
	ever access one of the two. Since gas is the only consumer of the
	assembly data, move it there. While doing so mark respective entities
	"static" in i386-gen (we may want to do away with i386_regtab_size
	altogether).

	This also shrinks the number of relocations to be processed for
	libopcodes.so by about 30%.

	gas: sframe: fine tune the fragment fixup for SFrame func info
	SFrame function info is an unsigned 8-bit field comprising of the following
	(from LSB to MSB):
	  - 4-bits: FRE type
	  - 1-bit: FRE start address encoding
	  - 3-bits: Unused

	At the moment, the most-significat 4-bits are zero (The FRE start
	address encoding of SFRAME_FDE_TYPE_PCINC has a value of zero, and the upper
	3-bits are unused). So the current implementation works without this patch.

	To be precise, however, the fragment fixup logic is meant to fixup only the
	least-significant 4-bits (i.e., only the FRE type needs to be updated
	according to the function size).

	This patch makes the gas implementation a bit more resilient: In the
	future, when the format does evolve to make use of the currently unused
	3-bits in various ways, the values in those 3-bits can be propagated
	unchanged while the fragment fixup continues to update the lowermost
	4-bits to indicate the selected FRE type.

	ChangeLog:

		* gas/gen-sframe.c (create_func_info_exp): New definition.
		(output_sframe_funcdesc): Call create_func_info_exp.
		* gas/sframe-opt.c (sframe_estimate_size_before_relax): The

	[aarch64] Add TPIDR2 register support for Linux
	With the AArch64 Scalable Matrix Extension we have a new TPIDR2 register, and
	it will be added to the existing NT_ARM_TLS register set. Kernel patches are
	being reviewed here:

	https://lore.kernel.org/linux-arm-kernel/20220818170111.351889-1-broonie@kernel.org/

	From GDB's perspective, we handle it in a similar way to the existing TPIDR
	register. But we need to consider cases of systems that only have TPIDR and
	systems that have both TPIDR and TPIDR2.

	With that in mind, the following patch adds the required code to support
	TPIDR2 and turns the org.gnu.gdb.aarch64.tls feature into a
	dynamically-generated target description as opposed to a static target
	description containing only TPIDR.

	That means we can remove the gdb/features/aarch64-tls.xml file and replace the
	existing gdb/features/aarch64-tls.c auto-generated file with a new file that
	dynamically generates the target description containing either TPIDR alone or
	TPIDR and TPIDR2.

	In the future, when *BSD's start to support this register, they can just
	enable it as is being done for the AArch64 Linux target.

	The core file read/write code has been updated to support TPIDR2 as well.

	On GDBserver's side, there is a small change to the find_regno function to
	expose a non-throwing version of it.

	It always seemed strange to me how find_regno causes the whole operation to
	abort if it doesn't find a particular register name. The patch moves code
	from find_regno into find_regno_no_throw and makes find_regno call
	find_regno_no_throw instead.

	This allows us to do register name lookups to find a particular register
	number without risking erroring out if nothing is found.

	The patch also adjusts the feature detection code for aarch64-fbsd, since
	the infrastructure is shared amongst all aarch64 targets. I haven't added
	code to support TPIDR2 in aarch64-fbsd though, as I'm not sure when/if
	that will happen.

	PR28306, segfault in _bfd_mips_elf_reloc_unshuffle
	Access to section data during relocation processing should be bounds
	checked, as it is in bfd_perform_relocation.  bfd_perform_relocation
	does these checks after any special_function is called.  So a reloc
	special_function needs to do its own bounds checking before accessing
	section data.  This patch adds many such checks to the mips backend.

	Checking mips relocs is not without some difficulty.  See the comment
	in _bfd_mips_reloc_offset_in_range.  In a multitple reloc sequence
	applied to the same location, relocs that may appear somewhere other
	than the last one of the sequence need to be treated specially since
	they apply to the addend for the next relocation rather than the
	section contents.  If the addend is in the section then it needs to be
	checked but not when the addend is in the reloc.  check_inplace
	handles this situation.  _bfd_mips_reloc_offset_in_range with
	check_shuffle handles the case where contents are shuffled before
	applying the relocation.

	gdb/testsuite: update a pattern in gdb_file_cmd
	When building GDB with the following CFLAGS and CXXFLAGS as part of
	configure line:

	    CFLAGS=-std=gnu11 CXXFLAGS=-std=gnu++11

	Then run the selftest.exp, I see:

	It is the fact that when I use the previously mentioned CFLAGS and
	CXXFLAGS as part of the configuration line, the default value (-O2 -g)
	is overridden, then GDB has no debug information.  When there's no debug
	information, GDB should not run the testcase in selftest.exp.

	The root cause of this FAIL is that the $gdb_file_cmd_debug_info didn't
	get the right value ("nodebug") during the gdb_file_cmd procedure.

	That's because in this commit,

	  commit 3453e7e409f44a79ac6695589836edb8a49bfb08

	gdb: skip objfiles with no BFD in DWARF unwinder
	While playing with JIT reader I experienced GDB to crash on null-pointer
	dereference when stepping through non-jitted code.

	The problem was that dwarf2_frame_find_fde () assumed that all objfiles
	have BFD but that's not always true. To address this problem, this
	commit skips such objfiles.

	To test the fix we put breakpoint in jit_function_add (). The JIT reader
	does not know how unwind this function so unwinding eventually falls
	back to DWARF unwinder which in turn iterates over objfiles. Since the
	the code is jitted, it is guaranteed it would eventually process JIT
	objfile.

	[gdb/testsuite] Make gdb.base/longjmp.exp FAIL more stable across archs
	When running test-case gdb.base/longjmp.exp on x86_64-linux, the master
	longjmp breakpoint is set using probes and the test-case passes:
	...
	(gdb) PASS: gdb.base/longjmp.exp: next to longjmp (1)
	next^M
	0x00000000004005cc      49        if (setjmp (env) == 0) /* patt1 */^M
	(gdb) PASS: gdb.base/longjmp.exp: next over longjmp(1)
	next^M
	56            resumes++;^M
	(gdb) PASS: gdb.base/longjmp.exp: next into else block (1)
	...

	However, if I disable
	create_longjmp_master_breakpoint_probe, we have instead:
	...
	(gdb) PASS: gdb.base/longjmp.exp: next to longjmp (1)
	next^M
	56            resumes++;^M
	(gdb) FAIL: gdb.base/longjmp.exp: next over longjmp(1)
	...

	At first glance, the failure mode doesn't look too bad: we stop
	a few insns later than the passing scenario.

	For contrast, if we do the same on powerpc64le, the failure mode is:
	...
	(gdb) PASS: gdb.base/longjmp.exp: next to longjmp (1)
	next^M
	^M
	Breakpoint 3, main () at longjmp.c:59^M
	59        i = 1; /* miss_step_1 */^M
	(gdb) FAIL: gdb.base/longjmp.exp: next over longjmp(1)
	...
	Here we only stop because of running into the safety net breakpoint at
	miss_step_1.

	So, how does this happen on x86_64?  Let's look at the code:
	...
	4005c7: e8 94 fe ff ff    call 400460 <_setjmp@plt>
	4005cc: 85 c0             test %eax,%eax
	4005ce: 75 1e             jne  4005ee <main+0x3b>
	4005d0: 8b 05 8e 0a 20 00 mov  0x200a8e(%rip),%eax # 601064 <longjmps>
	4005d6: 83 c0 01          add  $0x1,%eax
	4005d9: 89 05 85 0a 20 00 mov  %eax,0x200a85(%rip) # 601064 <longjmps>
	4005df: be 01 00 00 00    mov  $0x1,%esi
	4005e4: bf 80 10 60 00    mov  $0x601080,%edi
	4005e9: e8 82 fe ff ff    call 400470 <longjmp@plt>
	4005ee: 8b 05 74 0a 20 00 mov  0x200a74(%rip),%eax # 601068 <resumes>
	...
	The next over the longjmp call at 4005e9 is supposed to stop at the longjmp
	target at 4005cc, but instead we stop at 4005ee, where we have the step-resume
	breakpoint inserted by the next.  In other words, we accidentally "return"
	from the longjmp call to the insn immediately after it (even though
	a longjmp is a noreturn function).

	Try to avoid this accident and make the failure mode on x86_64 the same as on
	powerpc64le, by switching the then and else branch.

	Tested on x86_64-linux.

	gdb/testsuite: remove perror calls when failing to run
	I noticed that when running these two tests in sequence:

	    Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/arrayptr.exp ...
	    ERROR: GDB process no longer exists
	    ERROR: Couldn't run foo-all
	    Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/assign_1.exp ...

	The results in gdb.sum are:

	    Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/arrayptr.exp ...
	    PASS: gdb.ada/arrayptr.exp: scenario=all: compilation foo.adb
	    ERROR: GDB process no longer exists
	    UNRESOLVED: gdb.ada/arrayptr.exp: scenario=all: gdb_breakpoint: set breakpoint at foo.adb:40 (eof)
	    ERROR: Couldn't run foo-all
	    Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.ada/assign_1.exp ...
	    UNRESOLVED: gdb.ada/assign_1.exp: changing the language to ada
	    PASS: gdb.ada/assign_1.exp: set convenience variable $xxx to 1

	The UNRESOLVED for arrayptr.exp is fine, as GDB crashes in that test,
	while trying to run to main.  However, the UNRESOLVED in assign_1.exp
	doesn't make sense, GDB behaves as expected in that test:

	    (gdb) set lang ada^M
	    (gdb) UNRESOLVED: gdb.ada/assign_1.exp: changing the language to ada
	    print $xxx := 1^M
	    $1 = 1^M
	    (gdb) PASS: gdb.ada/assign_1.exp: set convenience variable $xxx to 1

	The problem is that arrayptr.exp calls perror when failing to run to
	main, then returns.  perror makes it so that the next test (as in
	pass/fail) will be recorded as UNRESOLVED.  However, here, the next test
	(as in pass/fail) is in the next test (as in .exp).  Hence the spurious
	UNRESOLVED in assign_1.exp.

	These perror when failing to run to X are not really useful, especially
	since runto records a FAIL on error, by default.  Remove all the
	perrors on runto failure I could find.

	When there wasn't one already, add a return statement when failing to
	run, to avoid running the test of the test unnecessarily.

	I thought of adding a check ran between test (in gdb_finish
	probably) where we would emit a warning if errcnt > 0, meaning a test
	quit and left a perror "active".  However, reading that variable would
	poke into the DejaGNU internals, not sure it's a good idea.

	libopcodes/mips: add support for disassembler styling
	This commit adds disassembler styling support for MIPS.  After this
	commit objdump and GDB will style disassembler output.

	This is a pretty straight forward change, we switch to use the
	disassemble_info::fprintf_styled_func callback, and pass an
	appropriate style through as needed.  No additional tricks were
	needed (compared to say i386, or ARM).

	Tested by running all of the objdump commands used by the gas
	testsuite and manually inspecting the styled output, everything looks
	reasonable, though I'm not a MIPS expert, so it is possible that I've
	missed some corner cases.  Worst case though is that something will be
	styled incorrectly, the actual content should be unchanged.

	All the gas, ld, and binutils tests still pass for me.

	opcodes/mips: use .word/.short for undefined instructions
	While working on disassembler styling for MIPS, I noticed that

	with no assembler directive prefix (e.g. without .word or .short).

	I think adding something like .word, or .short, helps to make it
	clearer the size of the value that is being displayed, and is inline
	with what many of the other libopcode disassemblers do.

	In this commit I've added the .word and .short directives, and updated
	all the tests that I spotted that failed as a result.

	PowerPC, fix gdb.reverse/finish-reverse-bkpt.exp and gdb.reverse/next-reverse-bkpt-over-sr.exp
	The tests set a break point with the command break *func.  This sets a
	breakpoint on the first instruction of the function.  PowerPC uses
	Global Entry Points (GEP) and Local Entry Points (LEP).  The first
	instruction in the function is the GEP.  The GEP sets up register
	r2 before reaching the LEP.  When the function is called with func() the
	function is entered via the LEP and the test fails because GDB does not
	see the breakpoint on the GEP.  However, if the function is called via a
	function pointer, execution begins at the GEP as the test expects.

	Currently finish-reverse-bkpt.exp uses source file finish-reverse.c and
	next-reverse-bpkt-over-sr.exp uses source file step-reverse.c  A new
	source file was created for tests finish-reverse-bkpt.exp and
	next-reverse-bkpt-over-sr.exp.  The new files use the new function
	pointer method to call the functions so the tests will work correctly on
	both PowerPC with a GEP and LEP as well as on other systems.  The GEP is
	the same as the LEP on non PowerPC systems.

	The expect files were changed to use the new source files and to set the
	initial break point for the rest of the test on the function pointer call
	for the function.

	This patch fixes two PowerPC test failures in each of the tests
	gdb.reverse/finish-reverse-bkpt.exp and
	gdb.reverse/next-reverse-bkpt-over-sr.exp.

	Patch tested on PowerPC and Intel X86-64 with no regressions.

	Add name canonicalization for C
	PR symtab/29105 shows a number of situations where symbol lookup can
	result in the expansion of too many CUs.

	What happens is that lookup_signed_typename will try to look up a type
	like "signed int".  In cooked_index_functions::expand_symtabs_matching,
	when looping over languages, the C++ case will canonicalize this type
	name to be "int" instead.  Then this method will proceed to expand
	every CU that has an entry for "int" -- i.e., nearly all of them.  A
	crucial component of this is that the caller, objfile::lookup_symbol,
	does not do this canonicalization, so when it tries to find the symbol
	for "signed int", it fails -- causing the loop to continue.

	This patch fixes the problem by introducing name canonicalization for
	C.  The idea here is that, by making C and C++ agree on the canonical
	name when a symbol name can have multiple spellings, we avoid the bad
	behavior in objfile::lookup_symbol (and any other such code -- I don't
	know if there is any).

	Unlike C++, C only has a few situations where canonicalization is
	needed.  And, in particular, due to the lack of overloading (thus
	avoiding any issues in linespec) and due to the way c-exp.y works, I
	think that no canonicalization is needed during symbol lookup -- only
	during symtab construction.  This explains why lookup_name_info is not
	touched.

	The stabs reader is modified on a "best effort" basis.

	The DWARF reader needed one small tweak in dwarf2_name to avoid a
	regression in dw2-unusual-field-names.exp.  I think this is adequately
	explained by the comment, but basically this is a scenario that should
	not occur in real code, only the gdb test suite.

	lookup_signed_typename is simplified.  It used to search for two
	different type names, but now gdb can search just for the canonical
	form.

	gdb.dwarf2/enum-type.exp needed a small tweak, because the
	canonicalizer turns "unsigned integer" into "unsigned int integer".
	It seems better here to use the correct C type name.

	gdb: remove prune_threads in thread_db_target::update_thread_list
	Pedro mentioned that this prune_threads call in
	thread_db_target::update_thread_list was not needed, and it was probably
	an oversight to leave it there in the work following commit e8032dde10b
	("Push pruning old threads down to the target").  That commit changed
	the "find new threads" target operation to "update thread list", making
	the target responsible of adding new threads and removing exited
	threads, rather than just adding new threads.  Commit e8032dde10b moved
	the prune_threads calls previously done in common code into each
	target's update_thread_list method, in order to keep the existing
	behavior, which is why this prune_threads call ended up there.

	In the mean time, the linux-nat target was taught to update_thread_list,
	and thread_db_target::update_thread_list defers to that for any live
	inferior, so the prune_threads call is not needed there.  Otherwise, the
	thread_db_target::update_thread_list implementation based on
	td_ta_thr_iter_p only knows how to add new threads, not how to delete
	exited threads, but that is only used for non-live inferiors, where
	threads can't exit anyway.  So the prune_threads call is not needed for
	that case either.

	Avoid timeouts in gdb.compile
	PR compile/29541 points out that some of the C++ tests in gdb.compile
	will time out when the glibc debuginfo is installed.  This was
	interfering with my hacking on gdb by making test runs extremely long,
	so I looked into it.

	Internally the bug seems to be that gdb tries to convert multiple
	symbols named "var" via the compiler interface; one such symbol (I
	didn't track it down too far) causes the C++ compiler plugin to crash.

	Unfortunately, the crash is reported as a timeout, as the gdb side of
	the plugin simply hangs.  This seems like a bug in the plugin RPC
	mechanism and, worse, apparently when I wrote this stuff I didn't
	really consider error reporting very much at all, so gdb can't really
	detect failures in the first place.

	Anyway... this patch works around the timeout by compiling a simple
	test that should provoke this bug, and then using "untested" if it
	notices a GCC crash.

	x86: rework of match_template()'s suffix checking
	(Ab)using i386_opcode_modifier for this has been overkill, as the logic
	doesn't really require the full structure. With the removal of
	LONG_DOUBLE_MNEM_SUFFIX and No_ldSuf there's no good reason at all
	anymore to pull out such a loop invariant: We're dealing a check of a
	bit in the loop for a simple comparison. Do the original compares inside
	the loop, thus also making it easier to understand what is actually
	being checked.

	x86: drop No_ldSuf
	With LONG_DOUBLE_MNEM_SUFFIX gone there'salso no use for No_ldSuf
	anymore.

	x86/Intel: drop LONG_DOUBLE_MNEM_SUFFIX
	With the removal of its use for FPU insns the suffix is now finally
	properly misnamed. Drop its use altogether, replacing it by a separate
	boolean instead.

	x86/Intel: restrict use of LONG_DOUBLE_MNEM_SUFFIX
	As a comment near the top of match_template() already says: We really
	only need this pseudo-suffix for far branch handling. Stop "deriving" it
	for floating point insns. (Don't bother renaming the now properly
	misnamed LONG_DOUBLE_MNEM_SUFFIX, to e.g. FAR_BRANCH_SUFFIX - it's going
	to disappear anyway.)

	section-select: Fix exclude-file-3
	this testcase wasn't correctly testing everything, it passed, even
	though sections from an excluded file were included.  Fixing this
	reveals a problem in the new section selector.  This fixes that as
	well.

	section-select: Remove unused code
	walk_wild_file, hence walk_wild_section and walk_wild_section_handler
	aren't called with the prefix tree.  Hence initialization of the latter
	and all potential special cases for it aren't used anymore.  That also
	removes the need to handler_data[] and some associated helper functions.
	So, remove all of that.

2022-11-30  Michael Matz  <matz@suse.de>

	section-select: Implement a prefix-tree
	Now that we have a list of potentially matching sections per wild
	statement we can actually pre-fill that one by going once over all input
	sections and match their names against a prefix-tree that points to the
	potentially matching wild statements.

	So instead of looking at all sections names for each glob for each wild
	statement we now look at the sections only once and then only check
	against those globs that have a possibility of a match at all (usually
	only one or two).

	This pushes the whole section selection off the profiles.

2022-11-30  Michael Matz  <matz@suse.de>

	section-select: Completely rebuild matches
	The check_relocs callback (and others) might have created new
	section behind our back and some of them (e.g. on powerpc the
	"linker stubs" .got) need to come in front of all others, despite
	being created late (a symptom would be "TOC opt*" failing on powerpc).

	This resets all section matches before updating for newly created
	sections (i.e. completely rebuilds the matches).

2022-11-30  Michael Matz  <matz@suse.de>

	section-select: Lazily resolve section matches
	and remember the results.  Before this the order of section matching
	is basically:

	  foreach script-wild-stmt S
	    foreach pattern P of S
	      foreach inputfile I
	        foreach section S of I
		  match S against P
		    if match: do action for S

	And this process is done three or four times: for each top-level call to
	walk_wild() or wild(), that is: check_input_sections, lang_gc_sections,
	lang_find_relro_sections and of course map_input_to_output_sections.

	So we iterate over all sections of all files many many times (for each
	glob).  Reality is a bit more complicated (some special glob types don't
	need the full iteration over all sections, only over all files), but
	that's the gist of it.

	For future work this shuffles the whole ordering a bit by lazily doing
	the matching process and memoizing results, trading a little memory for
	a 75% speedup of the overall section selection process.

	This lazy resolution introduces a problem with sections added late
	that's corrected in the next patch.

	While looking into Ada tasking a little, I noticed that no bounds

	x86: clean up after removal of support for gcc <= 2.8.1
	At the very least a comment in process_operands() is stale. Beyond that
	there are effectively two options:
	1) It is possible that FADDP and FMULP were mistakenly not marked as
	   being in need of dealing with the compiler anomaly, and hence the
	   respective templates weren't removed at the time when they should
	   have been.
	2) It is also possible that there are indeed uses known beyond compiler
	   generated output for these two commutative opcodes, and hence the
	   templates need to stay.
	To be on the safe side assume 2: Update the comment and fold the
	templates into their "normal" ones (utilizing D), adjusting consuming
	code accordingly.

	For FMULP also add a comment paralleling a similar one FADDP has.

	x86: drop FloatR
	There are just 4 templates using it, which can be easily identified by
	other means, as D is set only on a very limited number of FPU templates.
	Also move the respective conditional out of the code path taken by all
	"reverse match" insns (it probably should have been this way already
	before, to avoid the one conditional in the common case).

	With this the templates which had FloatR dropped no longer differ from
	their AT&T syntax + mnemonic counterparts - the only difference is now
	which of the two would be recognized. For this, however, we don't need
	two templates - we can simply arrange the condition for setting
	Opcode_FloatR accordingly.

	DW_OP_entry_value resolving cannot find DW_TAG_call_site 0x100006b0 in main

	The call site lookup fails because the call site label .LVL4:

	...
	Cannot find matching parameter at DW_TAG_call_site 0x10000690 at main
	$1 = <optimized out>
	...
	due to the fact that the call site has no call site parameters.

	The call site does have a reference to the corresponding function f1, with

	                          DW_OP_stack_value)
	...
	and we could use the fact that the current pc is in the 1000067c-10000680
	range, and that that the range starts at the start of the function, to deduce
	that DW_OP_GNU_entry_value: (DW_OP_reg3 (r3)) == DW_OP_reg3 (r3).
	But that's a non-trivial enhancement, filed as enhancement PR symtab/29836.

	Fix this by allowing <optimized out> for target powerpc and the gcc compiler.

	gdb/testsuite: make gdb_test_multiple return immediately if send_gdb fails
	In the failure seen by Philippe here:

	  https://inbox.sourceware.org/gdb-patches/20221120173024.3647464-1-philippe.waroquiers@skynet.be/

	... the testsuite only outputs PASSes, and an ERROR, resulting from an
	uncaught exception.  This is a bit sneaky, because ERRORs are not
	reported in the test summary.  In certain circumstances, it can be easy
	to miss.

	Normally, gdb_test_multiple outputs an UNRESOLVED when GDB crashes.  But
	this is only if it manages to send the command, and it's that command
	that crashes GDB.  Here, the ERROR is due to the fact that GDB had
	already crashed by the time we entered gdb_test_multiple and tried to
	send a command.  GDB was crashed by the previous "file" command, sent by
	gdb_unload.  Because gdb_unload uses bare expect, it didn't record a
	test failure when crashing GDB (this will be addressed separately).

	In this patch, I propose to make gdb_test_multiple call unresolved
	directly and return -1 send_gdb fails.  This way, if GDB is already
	crashed by the time we enter gdb_test_multiple, it will leave a trace in
	the test results in the form of an UNRESOLVED.  It will also spare us
	the not-so-useful-in-my-opinion TCL backtrace.

	Before, it looks like:

	gdb: mark disassembler function callback types as noexcept
	In disasm.h we define a set of types that are used by the various
	disassembler classes to hold callback functions before passing the
	callbacks into libopcodes.

	Because libopcodes is C code, and on some (many?) targets, C code is
	compiled without exception support, it is important that GDB not try
	to throw an exception over libopcode code.

	In the previous commit all the existing callbacks were marked as
	noexcept, however, this doesn't protect us from a future change to GDB
	either adding a new callback that is not noexcept, or removing the
	noexcept keyword from an existing callback.

	In this commit I mark all the callback types as noexcept.  This means
	that GDB's disassembler classes will no longer compile if we try to
	pass a callback that is not marked as noexcept.

	At least, that's the idea.  Unfortunately, it's not that easy.

	Before C++17, the noexcept keyword on a function typedef would be
	ignored, thus:

	  using func_type = void (*) (void) noexcept;

	  void
	  a_func ()
	  {
	    throw 123;
	  }

	  void
	  some_func (func_type f)
	  {
	    f ();
	  }

	  int
	  main ()
	  {
	    some_func (a_func);
	    return 0;
	  }

	Will compile just fine for C++11 and C++14 with GCC.  Clang on the
	other hand complains that 'noexcept' should not appear on function
	types, but then does appear to correctly complain that passing a_func
	is a mismatch in the set of exceptions that could be thrown.

	Switching to C++17 and both GCC and Clang correctly point out that
	passing a_func is an invalid conversion relating to the noexcept
	keyword.  Changing a_func to:

	  void
	  a_func () noexcept
	  { /* Nothing.  */ }

	And for C++17 both GCC and Clang compile this just fine.

	My conclusion then is that adding the noexcept keyword to the function
	types is pointless while GDB is not compiled as C++17, and silencing
	the warnings would require us to jump through a bunch of hoops.

	And so, in this commit, I define a macro LIBOPCODE_CALLBACK_NOEXCEPT,
	this macro expands to noexcept when compiling for C++17, but otherwise
	expands to nothing.  I then add this macro to the function types.

	I've compiled GDB as the default C++11 and also forced the compile to
	C++17.  When compiling as C++17 I spotted a few additional places
	where callbacks needed to be marked noexcept (these fixes were merged
	into the previous commit, but this confirmed to be that the macro is
	working as expected).

2022-11-28  Andrew Burgess  <aburgess@redhat.com>

	gdb/disasm: mark functions passed to the disassembler noexcept
	While working on another patch, Simon pointed out that GDB could be
	improved by marking the functions passed to the disassembler as
	noexcept.

	  https://sourceware.org/pipermail/gdb-patches/2022-October/193084.html

	The reason this is important is the on some hosts, libopcodes, being C
	code, will not be compiled with support for handling exceptions.  As
	such, an attempt to throw an exception over libopcodes code will cause
	GDB to terminate.

	See bug gdb/29712 for an example of when this happened.

	In this commit all the functions that are passed to the disassembler,
	and which might be used as callbacks by libopcodes are marked
	noexcept.

	Ideally, I would have liked to change these typedefs:

	  using read_memory_ftype = decltype (disassemble_info::read_memory_func);
	  using memory_error_ftype = decltype (disassemble_info::memory_error_func);
	  using print_address_ftype = decltype (disassemble_info::print_address_func);
	  using fprintf_ftype = decltype (disassemble_info::fprintf_func);
	  using fprintf_styled_ftype = decltype (disassemble_info::fprintf_styled_func);

	which are declared in disasm.h, as including the noexcept keyword.
	However, when I tried this, I ran into this warning/error:

	  In file included from ../../src/gdb/disasm.c:25:
	  ../../src/gdb/disasm.h: In constructor ‘gdb_printing_disassembler::gdb_printing_disassembler(gdbarch*, ui_file*, gdb_disassemble_info::read_memory_ftype, gdb_disassemble_info::memory_error_ftype, gdb_disassemble_info::print_address_ftype)’:
	  ../../src/gdb/disasm.h:116:3: error: mangled name for ‘gdb_printing_disassembler::gdb_printing_disassembler(gdbarch*, ui_file*, gdb_disassemble_info::read_memory_ftype, gdb_disassemble_info::memory_error_ftype, gdb_disassemble_info::print_address_ftype)’ will change in C++17 because the exception specification is part of a function type [-Werror=noexcept-type]
	    116 |   gdb_printing_disassembler (struct gdbarch *gdbarch,
	        |   ^~~~~~~~~~~~~~~~~~~~~~~~~

	So I've left that change out.  This does mean that if somebody adds a
	new use of the disassembler classes in the future, and forgets to mark
	the callbacks as noexcept, this will compile fine.  We'll just have to
	manually check for that during review.

	gdb/python: avoid throwing an exception over libopcodes code
	Bug gdb/29712 identifies a problem with the Python disassembler API.
	In some cases GDB will try to throw an exception through the
	libopcodes disassembler code, however, not all targets include
	exception unwind information when compiling C code, for targets that
	don't include this information GDB will terminate when trying to pass
	the exception through libopcodes.

	To explain what GDB is trying to do, consider the following trivial
	use of the Python disassembler API:

	  class ExampleDisassembler(gdb.disassembler.Disassembler):

	      class MyInfo(gdb.disassembler.DisassembleInfo):
	          def __init__(self, info):
	              super().__init__(info)

	          def read_memory(self, length, offset):
	              return super().read_memory(length, offset)

	      def __init__(self):
	          super().__init__("ExampleDisassembler")

	      def __call__(self, info):
	          info = self.MyInfo(info)
	          return gdb.disassembler.builtin_disassemble(info)

	This disassembler doesn't add any value, it defers back to GDB to do
	all the actual work, but it serves to allow us to discuss the problem.

	The problem occurs when a Python exception is raised by the
	MyInfo.read_memory method.  The MyInfo.read_memory method is called
	from the C++ function gdbpy_disassembler::read_memory_func.  The C++
	stack at the point this function is called looks like this:

	So gdbpy_disassembler::read_memory_func is called from the libopcodes
	disassembler to read memory, this C++ function then calls into user
	supplied Python code to do the work.

	If the user supplied Python code raises an gdb.MemoryError exception
	indicating the memory read failed, this is fine.  The C++ code
	converts this exception back into a return value that libopcodes can
	understand, and returns to libopcodes.

	However, if the user supplied Python code raises some other exception,
	what we want is for this exception to propagate through GDB and appear
	as if raised by the call to gdb.disassembler.builtin_disassemble.  To
	achieve this, when gdbpy_disassembler::read_memory_func spots an
	unknown Python exception, we must pass the information about this
	exception from frame #0 to frame #8 in the above backtrace.  Frame #8
	is the C++ implementation of gdb.disassembler.builtin_disassemble, and
	so it is this function that we want to re-raise the unknown Python
	exception, so the user can, if they want, catch the exception in their
	code.

	The previous mechanism by which the exception was passed was to pack
	the details of the Python exception into a C++ exception, then throw
	the exception from frame #0, and catch the exception in frame #8,
	unpack the details of the Python exception, and re-raise it.

	However, this relies on the exception passing through frames #1 to #7,
	some of which are in libopcodes, which is C code, and so, might not be
	compiled with exception support.

	This commit proposes an alternative solution that does not rely on
	throwing a C++ exception.

	When we spot an unhandled Python exception in frame #0, we will store
	the details of this exception within the gdbpy_disassembler object
	currently in use.  Then we return to libopcodes a value indicating
	that the memory_read failed.

	libopcodes will now continue to disassemble as though that memory read
	failed (with one special case described below), then, when we
	eventually return to disasmpy_builtin_disassemble we check to see if
	there is an exception stored in the gdbpy_disassembler object.  If
	there is then this exception can immediately be installed, and then we
	return back to Python, when the user will be able to catch the
	exception.

	There is one extra change in gdbpy_disassembler::read_memory_func.
	After the first call that results in an exception being stored on the
	gdbpy_disassembler object, any future calls to the ::read_memory_func
	function will immediately return as if the read failed.  This avoids
	any additional calls into user supplied Python code.

	My thinking here is that should the first call fail with some unknown
	error, GDB should not keep trying with any additional calls.  This
	maintains the illusion that the exception raised from
	MyInfo.read_memory is immediately raised by
	gdb.disassembler.builtin_disassemble.  I have no tests for this change
	though - to trigger this issue would rely on a libopcodes disassembler
	that will try to read further memory even after the first failed
	read.  I'm not aware of any such disassembler that currently does
	this, but that doesn't mean such a disassembler couldn't exist in the
	future.

	With this change in place the gdb.python/py-disasm.exp test should now
	pass on AArch64.

	Remove reset_ecs and execution_control_state::reset
	I noticed that execution_control_state has a 'reset' method, and
	there's also a 'reset_ecs' function that calls it.  This patch cleans
	this area up a little by adding a parameter to the constructor and (a
	change Simon suggested) removing the reset method.  Some extraneous
	variables are also removed, like:

	-      struct execution_control_state ecss;
	-      struct execution_control_state *ecs = &ecss;

	Here 'ecs' is never changed, so this patch removes it entirely in
	favor of just using the object everywhere.

	Regression tested on x86-64 Fedora 34.

	gdb: relax requirement for the map_failed stap probe to be present
	From glibc 2.35 and later, the "map_failed" stap probe is no longer
	included in glibc.  The removal of the probe looks like an accident,
	but it was caused by a glibc commit which meant that the "map_failed"
	probe could no longer be reached; the compiler then helpfully
	optimised out the probe.

	In GDB, in solib-svr4.c, we have a list of probes that we look for
	related to the shared library loading detection.  If any of these
	probes are missing then GDB will fall back to the non-probe based
	mechanism for detecting shared library loading.  The "map_failed"
	probe is include in the list of required probes.

	This means that on glibc 2.35 (or later) systems, GDB is going to
	always fall back to the non-probes based mechanism for detecting
	shared library loading.

	I raised a glibc bug to discuss this issue:

	  https://sourceware.org/bugzilla/show_bug.cgi?id=29818

	But, whatever the ultimate decision from the glibc team, given there
	are version of glibc in the wild without the "map_failed" probe, we
	probably should update GDB to handle this situation.

	The "map_failed" probe is already a little strange, very early
	versions of glibc didn't include this probe, so, in some cases, if
	this probe is missing GDB is happy to ignore it.  This is fine, the
	action associated with this probe inside GDB is DO_NOTHING, this means
	the probe isn't actually required in order for GDB to correctly detect
	the loading of shared libraries.

	In this commit I propose changing the rules so that any probe whose
	action is DO_NOTHING, is optional.

	There is one possible downside to this change, and that concerns 'set
	stop-on-solib-events on'.  If a probe is removed from glibc, but the
	old style breakpoint based mechanism is still in place within glibc
	for that same event, then GDB will stop when using the old style
	non-probe based mechanism, but not when using the probes based
	mechanism.

	For the map_failed case this is not a problem, both the map_failed
	probe, and the call to the old style breakpoint location were
	optimised out, and so neither event (probes based, or breakpoint
	based) will trigger.  This would only become an issue if glibc removed
	a probe, but left the breakpoint in place (this would almost certainly
	be a bug in glibc).

	For now, I'm proposing that we just don't worry about this.  Because
	some probes have actions that are not DO_NOTHING, then we know the
	user will always seem _some_ stops when a shared library is
	loaded/unloaded, and (I'm guessing), in most cases, that's all they
	care about.  I figure when someone complains then we can figure out
	what the right solution is then.

	With this commit in place, then, when using a glibc 2.35 or later
	system, GDB will once again use the stap probes for shared library
	detection.

	On x86_64-linux (where the test-case passes), a hardware watchpoint is used:

	...
	and after forcing "set can-use-hw-watchpoints 0" we can intermittently
	reproduce the same failure.

	In the gdb documentation related to watchpoints in multi-threaded programs, we
	read:
	...
	Warning: In multi-threaded programs, software watchpoints have only limited
	usefulness.  If GDB creates a software watchpoint, it can only watch the value
	of an expression in a single thread.  If you are confident that the expression
	can only change due to the current thread’s activity (and if you are also
	confident that no other thread can become current), then you can use software
	watchpoints as usual.  However, GDB may not notice when a non-current thread’s
	activity changes the expression.  (Hardware watchpoints, in contrast, watch an
	expression in all threads.)
	...

	Since the ada task construct is mapped onto threads, it seems that the
	same limitation holds for tasks.

	Fix this by using skip_hw_watchpoint_tests.

	Only use wild_sort_fast
	there's no reason why the tree-based variant can't always be used
	when sorting is required, it merely needs to also support filename
	sorting and have a fast path for insertion at end (aka rightmost tree
	leaf).

	The filename sorting isn't tested anywhere and the only scripttempl
	that uses it is avr (for 'SORT(*)(.ctors)'), and I believe even there it
	was a mistake.  Either way, this adds a testcase for filename sorting as
	well.

	Then the non-BST based sorting can be simplified to only support
	the fast case of no sorting required at all (at the same time renaming
	the two variants to _sort and _nosort).

	Special case more simple patterns
	fnmatch is slow, so avoiding it in more cases is good.  This implements
	a more generic version of match_simple_wild which needs some
	pre-processing of patterns.  In particular it supports patterns of the
	form PREFIX*SUFFIX (where all parts are optional), i.e. a super set of
	what's handled now.  Most section matchers of this form and hence don't
	need any calls to fnmatch anymore.

	We retain the implementation of match_simple_wild for the filename
	matchers (they aren't called often enough to matter).

	gdb/testsuite: fail if gdb_start_cmd fails
	I broke gdb.ada/start.exp, and did not notice it, because it outputs an
	UNTESTED if gdb_start_cmd fails.  I don't really see when start would
	fail and it's not a problem that should be looked at.  Change all spots
	that call untested after a gdb_start_cmd failure, use fail instead.

	Doing so caused some failures with the native-gdbserver board.  Some
	tests that use "start" were relying on the fact that start would fail
	with that board to just return with "untested".  Change them to add an
	early return if use_gdb_stub returns true.

	Some gdb.pascal tests also failed with native-gdbserver, because they
	did use gdb_start_cmd to start the inferior, for no good reason.
	Convert them to use runto_main instead, which does the right thing if
	the target is a stub.

	A further refactoring could be to make gdb_start_cmd match the expected
	breakpoint hit and the prompt, which it doesn't do currently (it leaves
	that to the callers, but not all of them do).

	When running the kill command, commit_resumed_state for the
	process_stratum_target (linux-nat, here) is true.  After the kill, when
	there are no more threads, commit_resumed_state is still true, as
	nothing touches this flag during the kill operation.  During the
	subsequent run command, run_command_1 does:

	    scoped_disable_commit_resumed disable_commit_resumed ("running");

	We would think that this would clear the commit_resumed_state flag of
	our native target, but that's not the case, because
	scoped_disable_commit_resumed iterates on non-exited inferiors in order
	to find active process targets.  And after the kill, the inferior is
	exited, and the native target was unpushed from it anyway.  So
	scoped_disable_commit_resumed doesn't touch the commit_resumed_state
	flag of the native target, it stays true.  When reaching target_wait, in
	startup_inferior (to consume the initial expect stop events while the
	inferior is starting up and working its way through the shell),
	commit_resumed_state is true, breaking the contract saying that
	commit_resumed_state is always false when calling the targets' wait
	method.

	(note: to be correct, I think that startup_inferior should toggle
	commit_resumed between the target_wait and target_resume calls, but I'll
	ignore that for now)

	I can see multiple ways to fix this.  In the end, we need
	commit_resumed_state to be cleared by the time we get to that
	target_wait.  It could be done at the end of the kill command, or at the
	beginning of the run command.

	To keep things in a coherent state, I'd like to make it so that after
	the kill command, when the target is left with no threads, its
	commit_resumed_state flag is left to false.  This way, we can keep
	working with the assumption that a target with no threads (and therefore
	no running threads) has commit_resumed_state == false.

	Do this by adding a scoped_disable_commit_resumed in target_kill.  It
	clears the target's commit_resumed_state on entry, and leaves it false
	if the target does not have any resumed thread on exit.  That means,
	even if the target has another inferior with stopped threads,
	commit_resumed_state will be left to false, which makes sense.

	Add a test that tries to cover various combinations of actions done
	while an inferior is running (and therefore while commit_resumed_state
	is true on the process target).

	The reason is a wrong current process when find_one_thread is called.
	The current process is the 2nd one, which was just attached.  It does
	not yet have thread_db data (proc->priv->thread_db is nullptr).  As we
	iterate on all threads of all process to fulfull the qxfer:threads:read
	request, we get to a thread of process 1 for which we haven't read
	thread_db information yet (lwp_info::thread_known is false), so we get
	into find_one_thread.  find_one_thread uses
	`current_process ()->priv->thread_db`, assuming the current process
	matches the ptid passed as a parameter, which is wrong.  A segfault
	happens when trying to dereference that thread_db pointer.

	Fix this by making find_one_thread not assume what the current process /
	current thread is.  If it needs to call into libthread_db, which we know
	will try to read memory from the current process, then temporarily set
	the current process.

	In the case where the thread is already know and we return early, we
	don't need to switch process.

	Add a test to reproduce this specific situation.

	[gdb/testsuite] Fix gdb.opt/solib-intra-step.exp for powerpc64le
	On powerpc64le-linux, I run into:
	...
	(gdb) PASS: gdb.opt/solib-intra-step.exp: first-hit

	(gdb) FAIL: gdb.opt/solib-intra-step.exp: second-hit

	It's a bit easier to understand what happens if we do a full stepping session:

	and compare that to the line info:

	So we step from line 29 to line 28, and back to line 29, which is behaviour
	that matches the line table.  The peculiar order is due to using optimization.
	The problem is that the test-case doesn't expect this order.

	Fix this by allowing this order in the test-case.

	gdb: fix assert when quitting GDB while a thread is stepping
	This commit addresses one of the issues identified in PR gdb/28275.

	Bug gdb/28275 identifies a number of situations in which this assert:

	  Assertion `!proc_target->commit_resumed_state' failed.

	could be triggered.  There's actually a number of similar places where
	this assert is found in GDB, the two of interest in gdb/28275 are in
	target_wait and target_stop.

	In one of the comments:

	  https://sourceware.org/bugzilla/show_bug.cgi?id=28275#c1

	steps to trigger the assertion within target_stop were identified when
	using a modified version of the gdb.threads/detach-step-over.exp test
	script.

	In the gdb.threads/detach-step-over.exp test, we attach to a
	multi-threaded inferior, and continue the inferior in asynchronous
	(background) mode.  Each thread is continuously hitting a conditional
	breakpoint where the condition is always false.  While the inferior is
	running we detach.  The goal is that we detach while GDB is performing a
	step-over for the conditional breakpoint in at least one thread.

	While detaching, if a step-over is in progress, then GDB has to
	complete the step over before we can detach.  This involves calling
	target_stop and target_wait (see prepare_for_detach).

	As far as gdb/28275 is concerned, the interesting part here, is the
	the process_stratum_target::commit_resumed_state variable must be
	false when target_stop and target_wait are called.

	This is currently ensured because, in detach_command (infrun.c), we
	create an instance of scoped_disable_commit_resumed, this ensures that
	when target_detach is called, ::commit_resumed_state will be false.

	The modification to the test that I propose here, and which exposed
	the bug, is that, instead of using "detach" to detach from the
	inferior, we instead use "quit".  Quitting GDB after attaching to an
	inferior will cause GDB to first detach, and then exit.

	When we quit GDB we end up calling target_detach via a different code
	path, the stack looks like:

	  #0 target_detach
	  #1 kill_or_detach
	  #2 quit_force
	  #3 quit_command

	Along this path there is no scoped_disable_commit_resumed created.
	::commit_resumed_state can be true when we reach prepare_for_detach,
	which calls target_wait and target_stop, so the assertion will trigger.

	In this commit, I propose fixing this by adding the creation of a
	scoped_disable_commit_resumed into target_detach.  This will ensure
	that ::commit_resumed_state is false when calling prepare_for_detach
	from within target_detach.

	I did consider placing the scoped_disable_commit_resumed in
	prepare_for_detach, however, placing it in target_detach ensures that
	the target's commit_resumed_state flag is left to false if the detached
	inferior was the last one for that target.  It's the same rationale as
	for patch "gdb: disable commit resumed in target_kill" that comes later
	in this series, but for detach instead of kill.

	detach_command still includes a scoped_disable_commit_resumed too, but I
	think it is still relevant to cover the resumption at the end of the
	function.

	RISC-V: Better support for long instructions (assembler)
	Commit bb996692bd96 ("RISC-V/gas: allow generating up to 176-bit
	instructions with .insn") tried to start supporting long instructions but
	it was insufficient.

	1.  It heavily depended on the bignum internals (radix of 2^16),
	2.  It generates "value conflicts with instruction length" even if a big
	    number instruction encoding does not exceed its expected length and
	3.  Because long opcode was handled separately (from struct riscv_cl_insn),
	    some information like DWARF line number correspondence was missing.

	To resolve these problems, this commit:

	1.  Handles bignum (and its encodings) precisely and
	2.  Incorporates long opcode handling into regular instruction handling.

	This commit will be tested on the separate commit.

	RISC-V: Better support for long instructions (disassembler)
	Commit bb996692bd96 ("RISC-V/gas: allow generating up to 176-bit
	instructions with .insn") tried to start supporting long instructions but
	it was insufficient.

	On the disassembler, correct ".byte" output was limited to the first 64-bits
	of an instruction.  After that, zeroes are incorrectly printed.

	Note that, it only happens on ".byte" output (instruction part) and not on
	hexdump (data) part.  For example, before this commit, hexdump and ".byte"
	produces different values:

	Assembly:
	  .insn 22, 0xfedcba98765432100123456789abcdef55aa33cc607f
	objdump output example (before the fix):
	  10:   607f 33cc 55aa cdef     .byte   0x7f, 0x60, 0xcc, 0x33, 0xaa, 0x55, 0xef, 0xcd, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
	  18:   89ab 4567 0123 3210
	  20:   7654 ba98 fedc

	Note that, after 0xcd (after first 64-bits of the target instruction), all
	".byte" values are incorrectly printed as zero while hexdump prints correct
	instruction bits.

	To resolve this, this commit adds "packet" argument to support dumping
	instructions longer than 64-bits (to print correct instruction bits on
	".byte").  This commit will be tested on the separate commit.

	Fix leak in the dwarf reader
	Valgrind reports a leak in the dwarf reader (see details below).
	The function dw2_get_file_names_reader is interning in the per_objfile
	all the file names it finds, except the name of 'fnd file name and directory'.
	Instead, it was xstrdup-ing the name.
	Fix the leaks by also interning the name.

	This was validated running the tests natively, and under valgrind.
	Leaks have decreased as mentionned below.
	Valgrind detected no error such as double free or use after free.

	fix leak in gdb_environ
	valgrind reports a leak when assigning a gdb_environ to another gdb_environ.
	The memory allocated for the target gdb_environ env variables is not released.
	The gdb_environ selftest reproduces the leak (see below).
	Fix the leak by clearing the target gdb_environ before std::move-ing the
	members.

	Tested natively and re-running all tests under valgrind.

	[gdb/server] Emit warning for SIGINT failure
	Consider the executable from test-case gdb.base/interrupt-daemon.exp.

	When starting it using gdbserver:
	...
	$ ./build/gdbserver/gdbserver localhost:2345 \
	  ./outputs/gdb.base/interrupt-daemon/interrupt-daemon
	...
	and connecting to it using gdb:
	...
	$ gdb -q -ex "target remote localhost:2345" \
	    -ex "set follow-fork-mode child" \
	    -ex "break daemon_main" -ex cont
	...
	we are setup to do the same as in the test-case: interrupt a running inferior
	using ^C.

	So let's try:
	...
	(gdb) continue
	Continuing.
	^C
	...
	After pressing ^C, nothing happens.  This a known problem, filed as
	PR remote/18772.

	The problem is that in linux_process_target::request_interrupt, a kill is used
	to send a SIGINT, but it fails.  And it fails silently.

	Make the failure verbose by adding a warning, such that the gdbserver output
	becomes more helpful:
	...
	Process interrupt-daemon created; pid = 15068
	Listening on port 2345
	Remote debugging from host ::1, port 35148
	Detaching from process 15068
	Detaching from process 15085
	gdbserver: Sending SIGINT to process group of pid 15068 failed: \
	  No such process
	...

	Note that the failure can easily be reproduced using the test-case and target
	board native-gdbserver:
	...
	(gdb) continue^M
	Continuing.^M
	PASS: gdb.base/interrupt-daemon.exp: fg: continue
	^CFAIL: gdb.base/interrupt-daemon.exp: fg: ctrl-c stops process (timeout)
	...
	as reported in PR server/23382.

	[gdb/testsuite] Don't generate core in gdb.base/bt-on-fatal-signal.exp
	When running test-case gdb.base/bt-on-fatal-signal.exp on powerpc64le-linux I
	noticed:
	...
	FAIL: gdb.base/bt-on-fatal-signal.exp: SEGV: scan for backtrace (timeout)
	...

	The timeout is 10 seconds, but generating the core file takes more than a
	minute, probably due to slow NFS.

	I managed to reproduce this behaviour independently of gdb, by compiling
	"int main (void) { __builtin_abort (); }" and running it, which took 1.5
	seconds for a core file 50 times smaller than the one for gdb.

	Fix this by preventing the core file from being generated, using a wrapper
	around gdb that does "ulimit -c 0".

	Tested on x86_64-linux.

	x86: widen applicability and use of CheckRegSize
	First of all make operand_type_register_match() apply to all sized
	operands, i.e. in Intel Syntax also to respective memory ones. This
	addresses gas wrongly accepting certain SIMD insns where register and
	memory operand sizes should match but don't. This apparently has
	affected all templates with one memory-only operand and one or more
	register ones, both permitting at least two sizes, due to CheckRegSize
	not taking effect.

	Then also add CheckRegSize to a couple of non-SIMD templates matching
	that same pattern of memory-only vs register operands. This replaces
	bogus (for Intel Syntax) diagnostics referring to a wrong suffix (when
	none was used at all) by "type mismatch" ones, just like already emitted
	for insns where the template allows a register operand alongside a
	memory one at any particular position.

	This also is a prereq to limiting (ideally eliminating in the long run)
	suffix "derivation" in Intel Syntax mode.

	While making the code adjustment also flip order of checks to do the
	cheaper one first in both cases.

	x86: add missing CheckRegSize
	To properly and predictably determine operand size encoding (operand
	size or REX.W prefixes), consistent operand sizes need to be specified.
	Add CheckRegSize where this was previously missing.

	x86: correct handling of LAR and LSL
	Both uniformly only ever take 16-bit memory operands while at the same
	time requiring matching (in size) register operands, which then also
	should disassemble that way. This in particular requires splitting each
	of the templates for the assembler and separating decode of the
	register and memory forms in the disassembler.

	Fix gdb.cp/gdb2495.exp on powerpc64le
	On powerpc64le-linux I ran into this FAIL:
	...
	(gdb) p exceptions.throw_function()^M
	terminate called after throwing an instance of 'int'^M
	^M
	Program received signal SIGABRT, Aborted.^M
	0x00007ffff7979838 in raise () from /lib64/libc.so.6^M
	The program being debugged was signaled while in a function called from GDB.^M
	GDB remains in the frame where the signal was received.^M
	To change this behavior use "set unwindonsignal on".^M
	Evaluation of the expression containing the function^M
	(SimpleException::throw_function()) will be abandoned.^M
	When the function is done executing, GDB will silently stop.^M
	(gdb) FAIL: gdb.cp/gdb2495.exp: call a function that raises an exception \
	  without a handler.
	...

	The following happens:
	- we start an inferior call
	- an internal breakpoint is set on the global entry point of std::terminate
	- the inferior call uses the local entry point
	- the breakpoint is not triggered
	- we run into std::terminate

	We can fix this by simply adding the missing gdbarch_skip_entrypoint call in
	create_std_terminate_master_breakpoint, but we try to do this a bit more
	generic, by:
	- adding a variant of function create_internal_breakpoint which takes a
	  minimal symbol instead of an address as argument
	- in the new function:
	  - using both gdbarch_convert_from_func_ptr_addr and gdbarch_skip_entrypoint
	  - documenting why we don't need to use gdbarch_addr_bits_remove
	  - adding a note about possibly
	    needing gdbarch_deprecated_function_start_offset.
	- using the new function in:
	  - create_std_terminate_master_breakpoint
	  - create_exception_master_breakpoint_hook, which currently uses only
	    gdbarch_convert_from_func_ptr_addr.

	Note: we could use the new function in more locations in breakpoint.c, but
	as we're not aware of any related failures, we declare this out of scope for
	this patch.

	Tested on x86_64-linux, powerpc64le-linux.

	RISC-V: Make R_RISCV_SUB6 conforms to riscv ABI standard
	According to the riscv psabi, R_RISCV_SUB6 only allows 6 least significant
	bits are valid, but since binutils implementation, we usually get 8 bits
	field for it.  That means, the high 2 bits could be other field and have
	different purpose.  Therefore, we should filter the 8 bits to 6 bits before
	calculate, and then only encode the valid 6 bits back.  By the way, we also
	need the out-of-range check for R_RISCV_SUB6, and the overflow checks for
	all R_RISCV_ADD/SUB/SET relocations, but we can add them in the future patches.

	regcache: Add collect/supply_regset variants that accept a register base.
	Some register sets described by an array of regcache_map_entry
	structures do not have fixed register numbers in their associated
	architecture but do describe a block of registers whose numbers are at
	fixed offsets relative to some base register value.  An example of
	this are the TLS register sets for the ARM and AArch64 architectures.

	Currently OS-specific architectures create register maps and register
	sets dynamically using the register base number.  However, this
	requires duplicating the code to create the register map and register
	set.  To reduce duplication, add variants of the collect_regset and
	supply_regset regcache methods which accept a base register number.
	For valid register map entries (i.e. not REGCACHE_MAP_SKIP), add this
	base register number to the value from the map entry to determine the

	readelf: use fseeko64 or fseeko if possible
	Changes readelf to make use first of fseeko64 and then fseeko,
	depending on which of those is available. If neither is available,
	reverts to the previous behavior of using fseek.

	This is necessary when building readelf for LLP64 systems, where a
	long will only be 32 bits wide. If the elf file in question is >= 2 GiB,
	that is greater than the max long value and therefore fseek will fail
	indicating that the offset is negative. On such systems, making use of
	fseeko64 or fseeko will result in the ability so seek past the 2 GiB
	max long boundary.

	Note that large archive handling in readelf remains to be fixed.

	  Thread 1 "zeoes" hit Breakpoint 1.2, some_func () at somefunc1.c:5

	In mi mode, bkpt_print_id also (optionally) prints a new table field "locno":
	  locno is printed when the breakpoint hit has more than one location.
	Note that according to the GDB user manual node 'GDB/MI Development and Front
	Ends', it is ok to add new fields without changing the MI version.

	Also, when a breakpoint is reached, the convenience variables
	$_hit_bpnum and $_hit_locno are set to the encountered breakpoint number
	and location number.

	$_hit_bpnum and $_hit_locno can a.o. be used in the command list of a
	breakpoint, to disable the specific encountered breakpoint, e.g.
	   disable $_hit_bpnum.$_hit_locno

	In case the breakpoint has only one location, $_hit_locno is set to
	the value 1, so as to allow a command such as:
	  disable $_hit_bpnum.$_hit_locno
	to disable the breakpoint even when the breakpoint has only one location.

	This also fixes a strange behaviour: when a breakpoint X has only
	one location,
	  enable|disable X.1
	is accepted but transforms the breakpoint in a multiple locations
	breakpoint having only one location.

	The changes in RFA v4 handle the comments of Tom Tromey:
	 - Changed convenience var names from $bkptno/$locno to
	   $_hit_bpnum/$_hit_locno.
	 - updated the tests and user manual accordingly.
	   User manual also explictly describes that $_hit_locno is set to 1
	   for a breakpoint with a single location.
	 - The variable values are now set in bpstat_do_actions_1 so that
	   they are set for silent breakpoints, and when several breakpoints
	   are hit at the same time, that the variables are set to the printed
	   breakpoint.

	The changes in RFA v3 handle the additional comments of Eli:
	 GDB/NEW:
	  - Use max 80-column
	  - Use 'code location' instead of 'location'.
	  - Fix typo $bkpno
	  - Ensure that disable $bkptno and disable $bkptno.$locno have
	    each their explanation inthe example
	  - Reworded the 'breakpoint-hit' paragraph.
	 gdb.texinfo:
	  - Use 'code location' instead of 'location'.
	  - Add a note to clarify the distinction between $bkptno and $bpnum.
	  - Use @kbd instead of examples with only one command.

	Compared to RFA v1, the changes in v2 handle the comments given by
	Keith Seitz and Eli Zaretskii:
	  - Use %s for the result of paddress
	  - Use bkptno_numopt_re instead of 2 different -re cases
	  - use C@t{++}
	  - Add index entries for $bkptno and $locno
	  - Added an example for "locno" in the mi interface
	  - Added examples in the Break command manual.

	RISC-V: Add 'Ssstateen' extension and its CSRs
	This commit adds 'Ssstateen' extension, which is a supervisor-visible view
	of the 'Smstateen' extension.  It means, this extension implements sstateen*
	and hstateen* CSRs of the 'Smstateen' extension.

	implementation simplicity, it is implemented so that 'Smstateen' implies
	'Ssstateen' (just like 'M' implies 'Zmmul').

	gdbserver: use current_process in ps_getpid
	The following patch ("gdbserver: switch to right process in
	find_one_thread") makes it so find_one_thread calls into libthread_db
	with a current process but no current thread.  This tripped on ps_getpid
	using current_thread in order to get the process' pid.  Get the pid from
	`current_process ()` instead, which removes the need to have a current
	thread.  Eventually, it would be good to get it from the
	gdb_ps_prochandle_t structure, to avoid the need for a current process
	as well.

	gdbserver/linux-x86: make is_64bit_tdesc accept thread as a parameter
	ps_get_thread_area receives as a parameter the lwpid it must work on.
	It then calls is_64bit_tdesc, which uses the current_thread as the
	thread to work on.  However, it is not said that both are the same.

	This became a problem when working in a following patch that makes
	find_one_thread switch to a process but to no thread (current_thread ==
	nullptr).  When libthread_db needed to get the thread area,
	is_64bit_tdesc would try to get the regcache of a nullptr thread.

	Fix that by making is_64bit_tdesc accept the thread to work on as a
	parameter.  Find the right thread from the context, when possible (when
	we know the lwpid to work on).  Otherwise, pass "current_thread", to
	retain the existing behavior.

	gdb/testsuite: rewrite gdb.cp/call-method-register.exp with dwarf assembler
	Convert the gdb.cp/call-method-register.exp test to make use of the
	DWARF assembler.

	The existing gdb.cp/call-method-register.exp test relies on a GCC
	extension - forcing a local variable into a particular named register.

	This means that the test will only work with Clang, and, as we have to
	name the register into which the variable will be placed, will only
	work for those targets where we've selected a suitable register,
	currently this is x86-64, i386, and ppc64.

	By switching to the DWARF assembler, the test will work with gcc and
	clang, and should work on most, if not all, architectures.

	The test creates a small structure, something that can fit within a
	register, and then tries to call a method on the structure from within
	GDB.  This should fail because GDB can't take the address of the in
	register structure (for the `this` pointer).

	As the test is for a failure case, then we don't really care _which_
	register the structure is in, and I take advantage of this for the
	DWARF assembler test, I just declare that the variable is in
	DW_OP_reg0, whatever that might be.  I've tested the new test on
	x86-64, ppc, aarch64, and risc-v, and the test runs, and passes on all
	these architectures, which is already more than we used to cover.

	Additionally, on x86-64, I've tested with Clang and gcc, and the test
	runs and passed with both compilers.

	gdb/testsuite: fix gdb.debuginfod/fetch_src_and_symbols.exp with Clang
	The gdb.debuginfod/fetch_src_and_symbols.exp test is showing a single
	failure when run with some older versions of Clang, e.g. 9.0.1.

	The problem appears to be with Clang's generated line table.  The test
	source looks like this:

	  int
	  main()
	  {
	    asm ("main_label: .globl main_label");
	    return 0;
	  }

	In GDB, when we 'start', we expect to stop at the 'return 0;' line.
	This is the behaviour when the compiler is gcc, or later versions of
	Clang.

	However, with Clang 9.0.2, I see GDB stop on the 'asm' line.

	In this commit I'll fix this issue by placing a breakpoint on the
	return line, and then using gdb_continue_to_breakpoint to ensure we
	have stopped in the correct place.

	Of course, using gdb_continue_to_breakpoint will only work if we are
	not already stopped at the breakpoint location, so I've added some
	filler work before the 'return 0;' line.  With this done we can use
	gdb_continue_to_breakpoint in all cases.

	As a result of adding the new filler work, one of the later tests,
	that used the 'list' command, no longer see the correct expected
	output (the top line of the source file is no longer included in the
	output).  I've fixed this by listing a known specific line, the test
	is checking that GDB managed to find the source file, it doesn't
	matter which source line we list, as long as we can list something.

	gdb/testsuite: rename source file gdb.debuginfod/main.c
	The test gdb.debuginfod/fetch_src_and_symbols.exp uses a source file
	named main.c.  I can't see any particular reason why the file is named
	as such.

	Usually test source files are named after the test script.

	This commit just renames the source file inline with the test script,
	and updates the call to standard_testfile (removing the reference to
	main.c).

	There's no particular reason for this change other than seeing the
	file named main.c made me thing that the source file must be shared
	with some other test (it isn't).

	There should be no change in what is tested after this commit.

	gdb/testsuite: add (and use) a new build-id compile option
	I noticed that the gdb.debuginfod/fetch_src_and_symbols.exp test was
	failing when run with Clang as the compiler.

	This test relies on the compiled binaries having a build-id within
	them.  For GCC, really GNU ld, the default is to always include a
	build-id.

	When compiling with Clang though, the default is for no build-id.

	I did consider *always* turning on the build-id feature when the
	compiler is Clang, but that felt a little weird.

	Instead, I propose that we add a new 'build-id' compiler option to
	gdb_compile, this flag indicates that the test _requires_ a build-id.
	In gcc_compile we can then add the required flags if the compiler is
	Clang so that we do get a build-id.

	With this change the gdb.debuginfod/fetch_src_and_symbols.exp test
	now (mostly) passes with Clang 9.0.1 and 15.0.2, and still passes with
	gcc.  The 'mostly' part is an unrelated issue, and will be addressed
	in a later commit in this series.

	gdb/testsuite: fix gdb.compile/compile-ops.exp with clang
	I noticed that the gdb.compile/compile-ops.exp test was failing when
	run with Clang as the compiler.

	This test makes use of the DWARF assembler, and, it turns out, uses
	a technique which is not portable to Clang.   This problem is
	described in the comment on the function_range proc in lib/dwarf.exp,
	the explanation is:

	  # If the compiler is gcc, we can do the following to get function start
	  # and end address too:
	  #
	  # asm ("func_start: .globl func_start");
	  # static void func (void) {}
	  # asm ("func_end: .globl func_end");
	  #
	  # however, this isn't portable, because other compilers, such as clang,
	  # may not guarantee the order of global asms and function.  The code
	  # becomes:
	  #
	  # asm ("func_start: .globl func_start");
	  # asm ("func_end: .globl func_end");
	  # static void func (void) {}

	These start/end labels are used for computing the function start, end,
	and length.  The portable solution is to place a label within the
	function, like this:

	  #  int main (void)
	  #  {
	  #    asm ("main_label: .globl main_label");
	  #    return 0;
	  #  }

	And make use of 'proc function_range' (from lib/dwarf.exp).

	So, that's what I do in this commit.

	One consequence of this change is that we need to compile the source
	file, and have it loaded into a GDB session, before calling
	function_range, so I've added an early call to prepare_for_testing.

	Additionally, this test script was generating the DWARF assembler into
	a file called gdbjit-ops.S, I suspect a copy and paste issue there, so
	I've switched this to use compile-ops-dbg.S instead, which is more
	inline with what other DWARF assembler tests do.

	The only other change, which might be a problem, is that I also
	deleted these two lines from the source file:

	  asm (".section \".text\"");
	  asm (".balign 8");

	These lines were setting the alignment of the .text section.  What I
	don't know is whether this was significant or not.  If it is
	significant, then I can't see why.

	On x86-64, the test still passes fine without these lines, but that
	doesn't mean the test wont start failing on some other architecture.

	Still, I figure, lets remove them, then, if/when we find a test that
	starts failing, we can add the lines back, along with an explanation
	for why the extra alignment is required.

	But, if people would prefer to be more conservative, then I'm happy to
	just add the lines back.

	gdb/testsuite: fix gdb.trace/unavailable-dwarf-piece.exp with Clang
	I noticed that the test gdb.trace/unavailable-dwarf-piece.exp was
	failing when run with Clang.  Or rather, the test was not running as
	the test executable failed to compile.

	The problem is that Clang was emitting this warning:

	  warning: argument unused during compilation: '-fdiagnostics-color=never' [-Wunused-command-line-argument]

	This warning is emitted when compiling the assembler file generated
	by the DWARF assembler.

	Most DWARF assembler tests generate the assembler file into a file
	with the '.S' extension.  However, this particular test uses a '.s'
	extension.

	Now a .S file will be passed through the preprocessor, while a .s will
	be sent straight to the assembler.  My guess is that Clang doesn't
	support the -fdiagnostics-color=never option for the assembler, but
	does for the preprocessor.

	That's a little annoying, but easily worked around.  We don't care if
	our assembler file is passed through the preprocessor, so, in this
	commit, I just change the file extension from .s to .S, and the
	problem is fixed.

	Currently, the unavailable-dwarf-piece.exp script names the assembler
	file using standard_output_file, in this commit I've switched to make
	use of standard_testfile, as that seems to be the more common way of
	doing this sort of thing.

	With these changes the test now passes with Clang 9.0.1 and 15.0.2,
	and also still passes with gcc.

	gdb/testsuite: don't avoid DWARF assembler tests with Clang
	Two tests make the claim that the DWARF assembler requires gcc,
	however, this isn't true.  I think at one point, when the DWARF
	assembler was first added, we did use some techniques that were not
	portable (see the comments in lib/dwarf.exp on function_range for
	details), however, I think most DWARF assembler tests will now work
	fine with Clang.

	The two tests that I modify in this commit both work fine with Clang,
	at least, I've tested with Clang 9.0.1 and 15.0.2, and don't see any
	problems, so I'm removing the early return logic that stops these
	tests from running with Clang.

	PowerPC, fix gdb.base/retval-large-struct.exp
	Support for printining non-trivial return values was recently added in
	commit:

	  commit a0eda3df5b750ae32576a9be092b361281a41787
	  Author: Carl Love <cel@us.ibm.com>
	  Date:   Mon Nov 14 16:22:37 2022 -0500

	    PowerPC, fix support for printing the function return value for non-trivial values.

	The functionality can now be used to fix gdb.base/retval-large-struct.exp.
	The test just needs to be compiled with -fvar-tracking to enable GDB to
	determine the address off the return buffer when the function is called.

	The current output from the test:

	34        return big_struct;
	(gdb) PASS: gdb.base/retval-large-struct.exp: continue to breakpoint: Break in print_large_struct
	finish
	warning: Cannot determine the function return value.
	Try compiling with -fvar-tracking.
	Run till exit from #0  return_large_struct () at binutils-gdb-current/gdb/testsuite/gdb.base/retval-large-struct.c:34
	main (argc=1, argv=0x7fffffffcd58) at binutils-gdb-current/gdb/testsuite/gdb.base/retval-large-struct.c:44
	44        return 0;
	Value returned has type: struct big_struct_t. Cannot determine contents
	(gdb) FAIL: gdb.base/retval-large-struct.exp: finish from return_large_struct
	testcase binutils-gdb-current/gdb/testsuite/gdb.base/retval-large-struct.exp completed in 1 seconds

	This patch adds the command line argument -fvar-tracking to enable gdb to
	determine the return vaule and thus fixing the test.

	Patch tested on Power 10 with no regressions.

	Change NULL to nullptr in gdb/infcmd.c and gdb/infrun.c
	The GDB coding standard specifies that nullptr should be used instead of
	NULL.  There are numerous uses of NULL and nullptr in files infcmd.c and
	infrun.c.  This patch replaces the various uses of NULL with nullptr in
	the source files.  The use of NULL in the comments was not changed.

	The patch does not introduce any functional changes.

	The patch has been tested on PowerPC and Intel X86_64 with no new unexpected
	test failures, unresolved tests, new core files etc.

	Add a new convenience variable $_inferior_thread_count that contains
	the number of live (non-exited) threads in the current inferior.  This
	can be used in command scripts, or breakpoint conditions, etc to
	adjust the behaviour for multi-threaded inferiors.

	This value is only stable in all-stop mode.  In non-stop mode, where
	new threads can be started, and existing threads exit, at any time,
	this convenience variable can give a different value each time it is
	evaluated.

	gdb/testsuite: fix failure in gdb.python/py-send-packet.exp
	While working on another patch I noticed that, when run on an AArch64
	target, the test gdb.python/py-send-packet.exp was failing:

	  Traceback (most recent call last):
	    File "<string>", line 1, in <module>
	    File "/tmp/build/gdb/testsuite/outputs/gdb.python/py-send-packet/py-send-packet.py",
	  line 106, in run_auxv_send_packet_test
	      assert string == expected_result
	  AssertionError
	  Error while executing Python code.
	  (gdb) FAIL: gdb.python/py-send-packet.exp: call python run_auxv_send_packet_test function

	The test uses 'maint packet ...' to send a packet to gdbserver, and
	then captures the output in TCL.  This output is then passed through
	to a Python function, which performs some actions using the Python
	API, and compares the results from the Python API to the results
	captured in TCL from 'maint packet ...'.

	The problem is that the output captured in TCL contains lots of things
	like '\x000', when this is passed through to Python the '\x' causes
	this to be treated as an escape code, which isn't what we want - we
	want the actual string "\x000".

	So, in the TCL part of the test we were expanding '\x' to '\\x', this
	seemed to work fine for my testing on x86-64.

	However, on AArch64 what I see is that the results from 'maint packet
	...' contain a literal '\' character followed by a literal 'x'
	character.  When GDB prints this in the 'maint packet' output, GDB
	escapes the '\' for us, thus we get '\\x' printed by 'maint packet'.

	However, now our TCL test script kicks in and tries to "fix" the '\x',
	this means we now have '\\\x', which isn't correct.

	The problem is that in the TCL script we are too restrictive, we
	expand '\x' to '\\x', but really, we should be expanding all '\'
	characters, regardless of what follows them.  This is what this patch
	does.

	After this the gdb.python/py-send-packet.exp test passes on AArch64
	for me.

	gdb/fortran/testsuite: print values and types of string variables
	While looking through the Fortran tests, I couldn't find a test of GDB
	printing the value and type of a Fortran string defined using the
	'character*SIZE' notation.

	This works fine in GDB right now, but I thought it wouldn't hurt to
	have a test for this, so this commit adds such a test.

	The test also includes printing a string that includes some embedded
	special characters: \n \r \t \000 - that's right, as Fortran strings
	are stored as an address and length, it is fine to include an embedded
	null, so this test includes an example of that.

	Standard Fortran doesn't support backslash escape sequences within
	strings, the special characters must be generated using the `achar`
	function.  However, when GDB prints the strings we currently print
	using the standard C like backslash sequences.

	I'm not currently proposing to change that behaviour, the backslash
	sequences are more compact than the standard Fortran way of doing
	things, and are so widely used that I suspect most Fortran programmers
	will understand them.

	Fix various procfs.c compilation errors
	procfs.c has accumulated several compilation errors lately (some of them
	new with GCC 12), which are fixed by this patch:

	* auxv_parse gets:

	/vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:144:7: error: ‘int
	procfs_target::auxv_parse(gdb_byte**, gdb_byte*, CORE_ADDR*, CORE_ADDR*)’
	marked ‘override’, but does not override
	  144 |   int auxv_parse (gdb_byte **readptr,
	      |       ^~~~~~~~~~

	  Obviouly, procfs.c was missed in the auxv_parse constification.

	* dead_procinfo has:

	/vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c: In function ‘void
	dead_procinfo(procinfo*, const char*, int)’:
	/vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:563:11: warning: the address
	of ‘procinfo::pathname’ will never be NULL [-Waddress]
	  563 |   if (pi->pathname)
	      |       ~~~~^~~~~~~~
	/vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:238:8: note:
	‘procinfo::pathname’ declared here
	  238 |   char pathname[MAX_PROC_NAME_SIZE];    /* Pathname to /proc entry */
	      |        ^~~~~~~~

	  The warning is correct, so the code can lose support for the NULL
	  pathname case.

	* create_inferior has this ugly warning:

	/vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c: In member function ‘virtual void procfs_target::create_inferior(const char*, const std::string&, char**, int)’:
	/vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:2815:19: warning: ‘char* std::strncpy(char*, const char*, size_t)’ output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation]
	 2815 |           strncpy (tryname, p, len);
	      |           ~~~~~~~~^~~~~~~~~~~~~~~~~
	/vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:2814:26: note: length computed here
	 2814 |             len = strlen (p);
	      |                   ~~~~~~~^~~

	  It seems that this is another case of GCC PR middle-end/88059, which
	  Martin Sebor refuses to fix.  So I'm using the hack suggested in the
	  PR to use memcpy instead of strncpy.

	* find_memory_regions_callback fails with

	  Again, procfs.c was overlooked when adding the new memory_tagged arg.
	  Unfortunately, it wasn't even documented in gdb/defs.h when it was

	After de-installing bzip2, I run into:
	...
	Running ppc64-symtab-cordic.exp ...
	sh: bzip2: command not found
	PATH: gdb.arch/ppc64-symtab-cordic.exp: failed bzip2 for \
	  src/gdb/testsuite/gdb.arch/cordic.ko.bz2
	...

	Fix these by:
	- using remote_exec instead of catch system, and
	- using file tail in the untested message.

	I've tried making output redirection work with remote_exec, but that seems to
	be broken, so we now:
	- copy the file $f.bz2 into the desired location $dir/$f.bz2, and
	- decompress the bz2 file using "bzip2 -df $dir/$f.bz2", resulting in a file
	  $dir/$f.

	Factor out new function decompress_bz2 to make the test-case less verbose, and
	also use it in gdb.arch/i386-biarch-core.exp.

	Tested on x86_64-linux, without and with bzip2 installed.

	bfd: linker: merge .sframe sections
	The linker merges all the input .sframe sections.  When merging, the
	linker verifies that all the input .sframe sections have the same
	abi/arch.

	The linker uses libsframe library to perform key actions on the
	.sframe sections - decode, read, and create output data.  This
	implies buildsystem changes to make and install libsframe before
	libbfd.

	The linker places the output .sframe section in a new segment of its
	own: PT_GNU_SFRAME.  A new segment is not added, however, if the
	generated .sframe section is empty.

	When a section is discarded from the final link, the corresponding
	entries in the .sframe section for those functions are also deleted.

	The linker sorts the SFrame FDEs on start address by default and sets
	the SFRAME_F_FDE_SORTED flag in the .sframe section.

	This patch also adds support for generation of SFrame unwind
	information for the .plt* sections on x86_64.  SFrame unwind info is
	generated for IBT enabled PLT, lazy/non-lazy PLT.

	The existing linker option --no-ld-generated-unwind-info has been
	adapted to include the control of whether .sframe unwind information
	will be generated for the linker generated sections like PLT.

	Changes to the linker script have been made as necessary.

	libsframe: add the SFrame library
	libsframe is a library that allows you to:
	- decode a .sframe section
	- probe and inspect a .sframe section
	- encode (and eventually write) a .sframe section.

	This library is currently being used by the linker, readelf, objdump.
	This library will also be used by the SFrame unwinder which is still
	to be upstream'd.

	The file include/sframe-api.h defines the user-facing APIs for decoding,
	encoding and probing .sframe sections. A set of error codes together
	with their error message strings are also defined.

	Endian flipping is performed automatically at read and write time, if
	cross-endianness is detected.

	gas: generate .sframe from CFI directives
	Currently supported for x86_64 and aarch64 only.

	[PS: Currently, the compiler has not been adapted to generate
	".cfi_sections" with ".sframe" in it.  The newly added command line
	option of --gsframe provides an easy way to try out .sframe support
	in the toolchain.]

	gas interprets the CFI directives to generate DWARF-based .eh_frame
	info.  These internal DWARF structures are now consumed by
	gen-sframe.[ch] sub-system to, in turn, create the SFrame unwind
	information.  These internal DWARF structures are read-only for the
	purpose of SFrame unwind info generation.

	SFrame unwind info generation does not impact .eh_frame unwind info
	generation.  Both .eh_frame and .sframe can co-exist in an ELF file,
	if so desired by the user.

	Recall that SFrame unwind information only contains the minimal
	necessary information to generate backtraces and does not provide
	information to recover all callee-saved registers.  The reason being
	that callee-saved registers other than FP are not needed for stack
	unwinding, and hence are not included in the .sframe section.

	Consequently, gen-sframe.[ch] only needs to interpret a subset of
	DWARF opcodes in gas.  More details follow.

	[Set 1, Interpreted] The following opcodes are interpreted:
	- DW_CFA_advance_loc
	- DW_CFA_def_cfa
	- DW_CFA_def_cfa_register
	- DW_CFA_def_cfa_offset
	- DW_CFA_offset
	- DW_CFA_remember_state
	- DW_CFA_restore_state
	- DW_CFA_restore

	[Set 2, Bypassed] The following opcodes are acknowledged but are not
	necessary for generating SFrame unwind info:
	- DW_CFA_undefined
	- DW_CFA_same_value

	Anything else apart from the two above-mentioned sets is skipped
	altogether.  This means that any function containing a CFI directive not
	in Set 1 or Set 2 above, will not have any SFrame unwind information
	generated for them.  Holes in instructions covered by FREs of a single
	FDE are not representable in the SFrame unwind format.

	As few examples, following opcodes are not processed for .sframe
	generation, and are skipped:
	- .cfi_personality*
	- .cfi_*lsda
	- .cfi_escape
	- .cfi_negate_ra_state
	- ...

	Not processing .cfi_escape, .cfi_negate_ra_state will cause SFrame
	unwind information to be absent for SFrame FDEs that contain these CFI
	directives, hence affecting the asynchronicity.

	x86-64 and aarch64 backends need to have a few new definitions and
	functions for .sframe generation.  These provide gas with architecture
	specific information like the SP/FP/RA register numbers and an
	SFrame-specific ABI marker.

	Lastly, the patch also implements an optimization for size, where
	specific fragments containing SFrame FRE start address and SFrame FDE
	function are fixed up.  This is similar to other similar optimizations
	in gas, where fragments are sized and fixed up when the associated
	symbols can be resolved.  This optimization is controlled by a #define
	SFRAME_FRE_TYPE_SELECTION_OPT and should be easy to turn off if needed.
	The optimization is on by default for both x86_64 and aarch64.

	The commit bbaabc767a4293492817a0840819aef2768cce90 introduced an

	gdb: use libtool in GDB_AC_CHECK_BFD
	The GDB_AC_CHECK_BFD macro defined in gdb/acinclude.m4 uses the
	AC_LINK_IFELSE autoconf macro in order to link a simple program to
	check features of libbfd.

	If libbfd's link dependencies change, it was necessary to reflect them
	either in the definition of the macro, or as a consequence of checking
	for them with an autoconf macro resulting in an addition to LIBS.

	This patch modifies the definition of the GDB_CHECK_BFD macro in order
	to use libtool to perform the test link.  This makes it possible to
	not have to list dependencies of libbfd (which are indirect to GDB) at
	all.

	After this patch:

	  configure:28553: checking for ELF support in BFD
	  configure:28573: ./libtool --quiet --mode=link gcc -o conftest \

	gdb/testsuite: get_set_option_choices: expect \r\n after each item
	I get some random failures since commit 8d45c3a82a0e ("[gdb/testsuite]
	Set completions to unlimited in get_set_option_choices"), which can be
	reproduced with:

	    $ make check-read1 TESTS="gdb.base/parse_number.exp"

	For instance:

	    set architecture A^M
	    Ambiguous item "A".^M
	    (gdb) FAIL: gdb.base/parse_number.exp: arch=A: set architecture A

	The problem is the regexp in get_set_option_choices, it is possible that
	is only matches part of a completion result.  With check-read1, that is
	always one letter.

	Fix this by expecting the \r\n at the end of the line, so we only match
	entire results.  Use ^ in match patterns to ensure we don't miss any
	output.

	[gdb/testsuite] Add REMOTE_TARGET_USERNAME in remote-gdbserver-on-localhost.exp
	As reported here
	( https://sourceware.org/pipermail/gdb-patches/2022-October/193147.html ) a
	number of test-cases fails with a remote target setup, for instance test-case
	gdb.base/print-file-var.exp.

	So, why don't we see these fails with our remote target boards in
	gdb/testsuite/boards, say remote-gdbserver-on-localhost.exp?

	The problem is that the target board uses the same machine and user for
	both (by-definition-local) build and remote target, and when using absolute
	pathnames to refer to files on build, we can access those files on target,
	which in a real remote target setup wouldn't be the case: we'd have to
	download them to target first, and then the filename would also be different.

	For aforementioned test-case, this happens when the name of a shared library is
	passed as absolute file name to gcc:
	...
	gcc ...  -DSHLIB_NAME="$outputs/gdb.base/print-file-var/\
	  print-file-var-lib2-hidden0-dlopen1-version_id_main0_c.so"
	...

	Make these problems visible with remote-gdbserver-on-localhost.exp by
	adding an option to specify a test account (still on the same machine)
	using REMOTE_TARGET_USERNAME.

	We make sure by restricting file permissions, that the test account cannot see
	the build files on the $USER account, and that the $USER account cannot see
	the target files on the test account.

	And so we can reproduce the reported fails:
	...
	$ cd build/gdb
	$ tc="gdb.base/print-file-var.exp"
	$ tb="--target_board remote-gdbserver-on-localhost"
	$ tbu="REMOTE_TARGET_USERNAME=remote-target"
	$ make check RUNTESTFLAGS="$tb $tbu $tc"
	   ...
	FAIL: gdb.base/print-file-var.exp: lang=c: hidden=0: dlopen=1: \
	  version_id_main=0: continue to STOP marker
	...

	PowerPC, fix support for printing the function return value for non-trivial values.
	Currently, a non-trivial return value from a function cannot currently be
	reliably determined on PowerPC.  This is due to the fact that the PowerPC
	ABI uses register r3 to store the address of the buffer containing the
	non-trivial return value when the function is called.  The PowerPC ABI
	does not guarantee the value in register r3 is not modified in the
	function.  Thus the value in r3 cannot be reliably used to obtain the
	return addreses on exit from the function.

	This patch adds a new gdbarch method to allow PowerPC to access the value
	of r3 on entry to a function. On PowerPC, the new gdbarch method attempts
	to use the DW_OP_entry_value for the DWARF entries, when exiting the
	function, to determine the value of r3 on entry to the function.  This
	requires the use of the -fvar-tracking compiler option to compile the
	user application thus generating the DW_OP_entry_value in the binary.  The
	DW_OP_entry_value entries in the binary file allows GDB to resolve the
	DW_TAG_call_site entries.  This new gdbarch method is used to get the
	return buffer address, in the case of a function returning a nontrivial
	data type, on exit from the function.  The GDB function should_stop checks
	to see if RETURN_BUF is non-zero.  By default, RETURN_BUF will be set to
	zero by the new gdbarch method call for all architectures except PowerPC.
	The get_return_value function will be used to obtain the return value on
	all other architectures as is currently being done if RETURN_BUF is zero.
	On PowerPC, the new gdbarch method will return a nonzero address in
	RETURN_BUF if the value can be determined.  The value_at function uses the
	return buffer address to get the return value.

	This patch fixes five testcase failures in gdb.cp/non-trivial-retval.exp.
	The correct function return values are now reported.

	Note this patch is dependent on patch: "PowerPC, function
	ppc64_sysv_abi_return_value add missing return value convention".

	This patch has been tested on Power 10 and x86-64 with no regressions.

	      gdb: on x86-64 non-trivial C++ objects are returned in memory

	      Fixes PR gdb/28681.  It was observed that after using the `finish`
	      command an incorrect value was displayed in some cases.  Specifically,
	      this behaviour was observed on an x86-64 target.

	The function:

	  enum return_value_convention
	  ppc64_sysv_abi_return_value (struct gdbarch *gdbarch, struct value *function,
	                               struct type *valtype, struct regcache *regcache,
	                               gdb_byte *readbuf, const gdb_byte *writebuf)

	should return RETURN_VALUE_STRUCT_CONVENTION if the valtype->code() is
	TYPE_CODE_STRUCT and if the language_pass_by_reference is not
	trivially_copyable.

	This patch adds the needed code to return the value
	RETURN_VALUE_STRUCT_CONVENTION in this case.

	With this patch, the five test cases still fail but with the message "Value
	returned has type: A. Cannot determine contents".  The PowerPC ABI stores
	the address of the buffer containing the function return value in register
	r3 on entry to the function.  However, the PowerPC ABI does not guarentee
	that r3 will not be modified in the function.  So when the function returns,
	the return buffer address cannot be reliably obtained from register r3.
	Thus the message "Cannot determine contents" is appropriate in this case.

	gdb/unittests: PR28413, suppress warnings generated by Gnulib
	Gnulib generates a warning if the system version of certain functions
	are used (to redirect the developer to use Gnulib version).  It caused a
	compiler error when...

	-   Compiled with Clang
	-   -Werror is specified (by default)
	-   C++ standard used by Clang is before C++17 (by default as of 15.0.0)
	    when this unit test is activated.

	This issue is raised as PR28413.

	However, previous proposal to fix this issue (a "fix" to Gnulib):
	<https://lists.gnu.org/archive/html/bug-gnulib/2021-10/msg00003.html>
	was rejected because it ruins the intent of Gnulib warnings.

	So, we need a Binutils/GDB-side solution.

	This commit tries to address this issue on the GDB side.  We have
	"include/diagnostics.h" to disable certain warnings only when necessary.

	This commit suppresses the Gnulib warnings by surrounding entire #include
	block with DIAGNOSTIC_IGNORE_USER_DEFINED_WARNINGS to disable Gnulib-
	generated warnings on all standard C++ header files.

	[gdb/testsuite] Run gdb.arch/ppc64-symtab-cordic.exp for --enable-targets=all
	While looking at test-case gdb.arch/ppc64-symtab-cordic.exp I realized that
	the test-case is too restrictive here:
	...
	if {![istarget "powerpc*"] || ![is_lp64_target]} {
	    verbose "Skipping powerpc64 separate debug file symtab test."
	    return
	}
	...
	and can also be run on x86_64-linux, if "set arch powerpc:common64" is
	supported, which is the case if we've build gdb with --enable-targets=all.

	Fix this by instead checking if powerpc:common64 is in the completion list for
	"set arch".

	This allows us to remove the 'untested "powerpc:common64 is not supported"'.

	While we're at it, clean up the test-case by using clean_restart.

	gdb: fix start breakpoint expression not working in some languages
	Commit 0be837be9fb4 ("gdb: make "start" breakpoint inferior-specific")
	regresses gdb.ada/start.exp:

	    (gdb) start
	    Error in expression, near `1'.
	    (gdb) UNTESTED: gdb.ada/start.exp: start failed to land inside the right procedure

	This is because in Ada, the equality operator is =, not ==.

	I checked the other languages supported by GDB, these other languages
	use = for equality:

	 - Pascal: tests like gdb.pascal/hello.exp are affected too
	 - Modula-2: I tried building a Modula-2 hello world using gm2, but it
	   seems like the generated DWARF doesn't specify the Modula-2 language
	   in the CUs, it's C++ and C, so the selected language isn't
	   "modula-2".  But if I manually do "set language modula-2" on a dummy
	   program and then "start", I get the same error.

	Other languages all use ==.

	So, a short term fix would be to use = or == in the expression, based on
	the current language.  If this was meant to be permanent, I would
	suggest adding something like an "equality_operator" method to
	language_defn, that returns the right equality operator for the
	language.  But the goal is to replace all this with proper
	inferior-specific breakpoints, so I hope all this is temporary.

	[gdb/testsuite] Better error checking in has_hw_wp_support
	With gdb 12.1, on powerpc64le I ran into ERRORs related to has_hw_wp_support
	usage, which was already fixed on trunk by commits:
	- 13f72372413 ("gdb/testsuite: fix gdb.base/break-idempotent.exp on ppc"), and
	- 01a32ee0b8c ("PowerPC, fix gdb.base/watchpoint.exp on Power 9")

	While looking into these ERRORs and the commits that fix them, it occurred to
	me that while the commits fix the root cause, the failure mode is not great.

	The test-cases expect a running instance of gdb upon return, which is not
	there, so there's an long stream of ERRORs generated as a result.

	Fix this at the start of has_hw_wp_support, by (instead of accomodating a
	running gdb instance by calling gdb_exit), checking whether it's called
	without a running gdb instance, and erroring out otherwise.  This way, there's
	just one error.

	I also noticed that in case we do an early exit due to !runto_main, we don't
	clean up, so copy the missing cleanups (gdb_exit and $obj file deletion) from
	the regular exit.

	Tested on x86_64-linux, using has_hw_wp_support for x86_64 in
	skip_hw_watchpoint_tests.

	gdb/py-inferior: Keep inferior threads in a map
	The python code maintains a list of threads for each inferior.  This
	list is implemented as a linked list.  When the number of threads grows
	high, this implementation can begin to be a performance bottleneck as
	finding a particular thread_object in the list has a complexity of O(N).

	We see this in ROCgdb[1], a downstream port of GDB for AMDGUP.  On
	AMDGPU devices, the number of threads can get significantly higher than
	on usual GDB workloads.

	In some situations, we can reach the end of the inferior process with
	GDB still having a substantial list of known threads.  While running
	target_mourn_inferior, we end up in inferior::clear_thread_list which
	iterates over all remaining threads and marks each thread exited.  This
	fires the gdb::observers::thread_exit observer and eventually
	py-inferior.c:set_thread_exited gets called.  This function searches in
	the linked list with poor performances.

	This patch proposes to change the linked list that keeps the per
	inferior_object list of thread_objects into a std::unordered_map.  This
	allows to have the search operation complexity be O(1) on average
	instead of O(N).

	With this patch, we can complete clear_thread_list in about 2.5 seconds
	compared to 10 minutes without it.

	Except for the performance change, no user visible change is expected.

	Regression tested on Ubuntu-22.04 x86_64.

	Make sure a copy_insn_closure is available when we have a match in copy_insn_closure_by_addr
	PR gdb/29272

	Investigating PR29272, it was mentioned a particular test used to work on
	GDB 10, but it started failing with GDB 11 onwards. I tracked it down to
	some displaced stepping improvements on commit
	187b041e2514827b9d86190ed2471c4c7a352874.

	In particular, one of the corner cases using copy_insn_closure_by_addr got
	silently broken. It is hard to spot because it doesn't have any good tests
	for it, and the situation is quite specific to the Arm target.

	Essentially, the change from the displaced stepping improvements made it so
	we could still invoke copy_insn_closure_by_addr correctly to return the
	pointer to a copy_insn_closure, but it always returned nullptr due to
	the order of the statements in displaced_step_buffer::prepare.

	The way it is now, we first write the address of the displaced step buffer
	to PC and then save the copy_insn_closure pointer.

	The problem is that writing to PC for the Arm target requires figuring
	out if the new PC is thumb mode or not.

	With no copy_insn_closure data, the logic to determine the thumb mode
	during displaced stepping doesn't work, and gives random results that
	are difficult to track (SIGILL, SIGSEGV etc).

	Fix this by reordering the PC write in displaced_step_buffer::prepare
	and, for safety, add an assertion to
	displaced_step_buffer::copy_insn_closure_by_addr so GDB stops right
	when it sees this invalid situation. If this gets broken again in the
	future, it will be easier to spot.

	gdb/testsuite: skip gdb.cp/anon-struct.exp when using Clang
	When Clang compiles anonymous structures, it does not add linkage names in
	their dwarf representations. This is compounded by Clang not adding linkage
	names to subprograms of those anonymous structs (for instance, the
	constructor). With these 2 things together, GDB is unable to refer to
	any of them, so there is no way to pass any of the tests of
	gdb.cp/anon-struct.exp

	Since this isn't a bug on Clang or GDB according to the DWARF
	specifications as DW_AT_name is optional for all DIEs, the test was marked
	as untested.

	Since I was already touching the file, I also added a comment at the top

	gdb/testsuite: account for clang's nested destructor calls on gdb.cp/mb-ctor.exp
	When compiling virtual classes's destructors, two versions are compiled,
	one with a single parameter (this) and the other with 2 parameters (this
	and vtt).

	GCC's compilation makes it so either the version with 1
	parameter or the one with 2 parameters is called, depending on whether
	the destructor is being called by the class itself or by an inherited
	class. On the test gdb.cp/mb-ctor.exp, this means that the breakpoint
	set at the destructor will be hit 4 times.

	Clang, on the other hand, makes the single-parameter version call the 2
	parameter version, probably in an attempt to reduce the size of the
	resulting executable. This means that the gdb.cp/mb-ctor.exp will hit 6
	breakpoints before finishing, and is the reason why this test was
	failing. To make this test stop failing, a compiler check is added and
	another "continue" instruction is issued to account for this difference.

	gdb/testsuite: enable running gdb.cp/classes.exp with clang
	When attempting to run the gdb.cp/classes.exp test using Clang++, the
	test fails to prepare with -Wnon-c-typedef-for-linkage like the
	previously fixed gdb.cp/class2.exp. Upon fixing this, the test shows 5
	unexpected failures. One such failures is:

	ptype/r class class_with_public_typedef
	type = class class_with_public_typedef {
	  private:
	    int a;

	(gdb) FAIL: gdb.cp/classes.exp: ptype class class_with_public_typedef // wrong access specifier for typedef: private

	While g++ provided the following output:

	    typedef int INT;
	}
	(gdb) PASS: gdb.cp/classes.exp: ptype class class_with_public_typedef

	This error happens because Clang does not add DW_AT_accessibility to
	typedefs inside classes, and without this information GDB defaults to
	assuming the typedef is private.  Since there is nothing that GDB can do
	about this, these tests have been set as xfails, and Clang bug 57608 has
	been filed.

	PR28834, PR26946 sanity checking section size
	This patch provides a new function to sanity check section sizes.
	It's mostly extracted from what we had in bfd_get_full_section_contents
	but also handles compressed debug sections.
	Improvements are:
	- section file offset is taken into account,
	- added checks that a compressed section can be read from file.

	The function is then used when handling multiple .debug_* sections
	that need to be read into a single buffer, to sanity check sizes
	before allocating the buffer.

	    (gdb) FAIL: gdb.threads/vfork-multi-inferior.exp: method=non-stop: start inferior 1

	What happens is:

	 1. We start inferior 2 with "run&", it runs very slowly, takes time to
	    get to main
	 2. We switch to inferior 1, and run "start"
	 3. The temporary breakpoint inserted by "start" applies to all inferiors
	 4. Inferior 2 hits that breakpoint and GDB reports that hit

	To avoid this, breakpoints inserted by "start" should be
	inferior-specific.  However, we don't have a nice way to make
	inferior-specific breakpoints yet.  It's possible to make
	pspace-specific breakpoints (for example how the internal_breakpoint
	constructor does) by creating a symtab_and_line manually.  However,
	inferiors can share program spaces (usually on particular embedded
	targets), so we could have a situation where two inferiors run the same
	code in the same program space.  In that case, it would just not be
	possible to insert a breakpoint in one inferior but not the other.

	A simple solution that should work all the time is to add a condition to
	the breakpoint inserted by "start", to check the inferior reporting the
	hit is the expected one.  This is what this patch implements.

	Add a test that does:

	 - start in background inferior 1 that sleeps before reaching its main
	   function (using a sleep in a global C++ object's constructor)
	 - start inferior 2 with the "start" command, which also sleeps before
	   reaching its main function
	 - validate that we hit the breakpoint in inferior 2

	Without the fix, we hit the breakpoint in inferior 1 pretty much all the
	time.  There could be some unfortunate scheduling causing the test not
	to catch the bug, for instance if the scheduler decides not to schedule
	inferior 1 for a long time, but it would be really rare.  If the bug is
	re-introduced, the test will catch it much more often than not, so it
	will be noticed.

	gdb: add special handling for frame level 0 in frame_info_ptr
	I noticed this problem while preparing the initial submission for the
	ROCm GDB port.  One particularity of this patch set is that it does not
	support unwinding frames, that requires support of some DWARF extensions
	that will come later.  It was still possible to run to a breakpoint and
	print frame #0, though.

	When rebasing on top of the frame_info_ptr work, GDB started tripping on
	a prepare_reinflate call, making it not possible anymore to event print
	the frame when stopping on a breakpoint.  One thing to know about frame
	0 is that its id is lazily computed when something requests it through
	get_frame_id.  See:

	  https://gitlab.com/gnutools/binutils-gdb/-/blob/23912acd402f5af9caf91b257e5209ec4c58a09c/gdb/frame.c#L2070-2080

	So, up to that prepare_reinflate call, frame 0's id was not computed,
	and prepare_reinflate, calling get_frame_id, forces it to be computed.
	Computing the frame id generally requires unwinding the previous frame,
	which with my ROCm GDB patch fails.  An exception is thrown and the
	printing of the frame is simply abandonned.

	Regardless of this ROCm GDB problem (which is admittedly temporary, it
	will be possible to unwind with subsequent patches), we want to avoid
	prepare_reinflate to force the computing of the frame id, for the same
	reasons we lazily compute it in the first place.

	In addition, frame 0's id is subject to change across a frame cache
	reset.  This is why save_selected_frame and restore_selected_frame have
	special handling for frame 0:

	  https://gitlab.com/gnutools/binutils-gdb/-/blob/23912acd402f5af9caf91b257e5209ec4c58a09c/gdb/frame.c#L1841-1863

	For this last reason, we also need to handle frame 0 specially in
	prepare_reinflate / reinflate.  Because the frame id of frame 0 can
	change across a frame cache reset, we must not rely on the frame id from
	that frame to reinflate it.  We should instead just re-fetch the current
	frame at that point.

	This patch adds a frame_info_ptr::m_cached_level field, set in
	frame_info_ptr::prepare_reinflate, so we can tell if a frame is frame 0.
	There are cases where a frame_info_ptr object wraps a sentinel frame,
	for which frame_relative_level returns -1, so I have chosen the value -2
	to represent "invalid frame level", for when the frame_info_ptr object
	is empty.

	In frame_info_ptr::prepare_reinflate, only cache the frame id if the
	frame level is not 0.  It's fine to cache the frame id for the sentinel
	frame, it will be properly handled by frame_find_by_id later.

	In frame_info_ptr::reinflate, if the frame level is 0, call
	get_current_frame to get the target's current frame.  Otherwise, use
	frame_find_by_id just as before.

	This patch should not have user-visible changes with upstream GDB.  But
	it will avoid forcing the computation of frame 0's when calling
	prepare_reinflate.  And, well, it fixes the upcoming ROCm GDB patch
	series.

	gdb: add missing prepare_reinflate call in print_frame_info
	print_frame_info calls frame_info_ptr::reinflate, but not
	frame_info_ptr::prepare_reinflate, add the call to prepare_reinflate.
	It works right now, because all callers of print_frame_info that could
	possibly lead to the pretty printers being called, and the frame_info
	objects being invalidated, do call prepare_reinflate themselves.  And
	since the cached frame id is copied when passing a frame_info_ptr by
	value, print_frame_info does have a cached frame id on entry.  So
	technically, this change isn't needed.  But I don't think it's good for
	a function to rely on its callers to have called prepare_reinflate, if
	it intends to call reinflate.

	    /home/smarchi/src/binutils-gdb/gdb/frame-info.c:42: internal-error: reinflate: Assertion `frame_id_p (m_cached_id)' failed.

	This is because the code in backtrace_command_1 to manually reinflate
	`fi` steps overs frame_info_ptr's toes.

	When calling

	    fi.prepare_reinflate ();

	`fi` gets properly filled with the cached frame id.  But when this
	happens:

	    fi = frame_find_by_id (frame_id);

	`fi` gets replaced by a brand new frame_info_ptr that doesn't have a
	cached frame id.  Then this is called without a cached frame id:

	    fi.reinflate ();

	That doesn't cause any problem currently, since

	 - the gdb_assert in the reinflate method doesn't actually do anything
	   (the following patch fixes that)
	 - `fi.m_ptr` will always be non-nullptr, since we just got it from
	   frame_find_by_id, so reinflate will not do anything, it won't try to
	   use m_cached_id

	Fix that by removing the code to manually re-fetch the frame.  That
	should be taken care of by frame_info_ptr::reinflate.

	Note that the old code checked if we successfully re-inflated the frame
	or not, and if not it did emit a warning.  The equivalent in
	frame_info_ptr::reinflate asserts that the frame has been successfully
	re-inflated.  It's not clear if / when this can happen, but if it can
	happen, we'll need to find a solution to this problem globally
	(everywhere a frame_info_ptr can be re-inflated), not just here.  So I
	propose to leave it like this, until it does become a problem.

	This is another case of frame_info being invalidated under a function's

	print_frame_args knows that print_frame_arg can invalidate frame_info
	objects, and therefore calls prepare_reinflate/reinflate.  However,
	info_frame_command_core has a separate frame_info_ptr instance (it is
	passed by value / copy).  So info_frame_command_core needs to know that

	gdb: clear other.m_cached_id in frame_info_ptr's move ctor
	We do it in the move assignment operator, so I think it makes sense to
	do it here too for consistency.  I don't think it's absolutely necessary
	to clear the other object's fields (in other words, copy constructor and
	move constructor could be the same), as there is no exclusive resource
	being transfered.  The important thing is to leave the moved-from object
	in an unknown, but valid state.  But still, I think that clearing the
	fields of the moved-from object is not a bad idea, it helps ensure we
	don't rely on the moved-from object after.

	gdb/c++: Improve error messages in overload resolution
	When resolving overloaded functions, GDB relies on knowing relationships
	between types, i.e. if a type inherits from another. However, some
	compilers may not add complete information for given types as a way to
	reduce unnecessary debug information. In these cases, GDB would just say
	that it couldn't resolve the method or function, with no extra
	information.

	The problem is that sometimes the user may not know that the type
	information is incomplete, and may just assume that there is a bug in
	GDB. To improve the user experience, we attempt to detect if the
	overload match failed because of an incomplete type, and warn the user
	of this.

	This commit also adds a testcase confirming that the message is only
	triggered in the correct scenario. This test was not developed as an
	expansion of gdb.cp/overload.cc because it needed the dwarf assembler,
	and porting all of overload.cc seemed unnecessary.

	gdb/testsuite: Fix rtld-step-nodebugsym.exp
	The test case introduced in bafcc335266 (Fix stepping in rtld without
	debug symbol) fails on some systems as reported by PR/29768.  This can
	be seen if the system does not have debug info for the libc:

	  (gdb) step^M
	  Single stepping until exit from function main,^M
	  which has no line number information.^M
	  hello world[Inferior 1 (process 48203) exited normally]^M
	  (gdb) PASS: gdb.base/rtld-step-nodebugsym.exp: step
	  continue^M
	  The program is not being run.^M
	  (gdb) FAIL: gdb.base/rtld-step-nodebugsym.exp: continue until exit (the program is no longer running)

	Without glibc debug info, GDB steps until the program finishes, and
	then "gdb_continue_to_end" fails.

	As this test was designed to check that GDB does not crash in the "step"
	command, the continue does not carry real meaning to the test.

	Replace it by "print 0" so we still check that after the step command
	GDB is still alive, which is what we care about.

	Tested on Ubuntu-22.04 x86_64, with and without libc6-dbg.

	gdb/linux-nat: get core count using /sys/devices/system/cpu/possible
	I get this test failure on my CI;

	  FAIL: gdb.base/info-os.exp: get process list

	The particularity of this setup is that builds are done in containers
	who are allocated 4 CPUs on a machine that has 40.  The code in
	nat/linux-osdata.c fails to properly fetch the core number for each
	task.

	linux_xfer_osdata_processes uses `sysconf (_SC_NPROCESSORS_ONLN)`, which
	returns 4, so it allocates an array of 4 integers.  However, the core
	numbers read from /proc/pid/task/tid/stat, by function
	linux_common_core_of_thread, returns a value anywhere between 0 and 39.
	The core numbers above 3 are therefore ignored, many processes end up
	with no core value, and the regexp in the test doesn't match (it
	requires an integer as the core field).

	The way this the CPUs are exposed to the container is that the container
	sees 40 CPUs "present" and "possible", but only 4 arbitrary CPUs
	actually online:

	    root@ci-node-jammy-amd64-04-08:~# cat /sys/devices/system/cpu/present
	    0-39
	    root@ci-node-jammy-amd64-04-08:~# cat /sys/devices/system/cpu/online
	    5,11,24,31
	    root@ci-node-jammy-amd64-04-08:~# cat /sys/devices/system/cpu/possible
	    0-39

	The solution proposed in this patch is to find out the number of
	possible CPUs using /sys/devices/system/cpu/possible.  In practice, this
	will probably always contain `0-N`, where N is the number of CPUs, minus
	one.  But the documentation [1] doesn't such guarantee, so I'll assume
	that it can contain a more complex range list such as `2,4-31,32-63`,
	like the other files in that directory can have.  The solution is to
	iterate over these numbers to find the highest possible CPU id, and
	use that that value plus one as the size of the array to allocate.

	[gdb/cli] Make quit really quit after remote connection closed
	Consider a hello world a.out, started using gdbserver:
	...
	$ gdbserver --once 127.0.0.1:2345 ./a.out
	Process ./a.out created; pid = 15743
	Listening on port 2345
	...
	that we can connect to using gdb:
	...
	$ gdb -ex "target remote 127.0.0.1:2345"
	Remote debugging using 127.0.0.1:2345
	Reading /home/vries/a.out from remote target...
	  ...
	0x00007ffff7dd4550 in _start () from target:/lib64/ld-linux-x86-64.so.2
	(gdb)
	...

	After that, we can for instance quit with confirmation:
	...
	(gdb) quit
	A debugging session is active.

	        Inferior 1 [process 16691] will be killed.

	Quit anyway? (y or n) y
	$
	...

	Or, kill with confirmation and quit:
	...
	(gdb) kill
	Kill the program being debugged? (y or n) y
	[Inferior 1 (process 16829) killed]
	(gdb) quit
	$
	...

	Or, monitor exit, kill with confirmation, and quit:
	...
	(gdb) monitor exit
	(gdb) kill
	Kill the program being debugged? (y or n) y
	Remote connection closed
	(gdb) quit
	$
	...

	But when doing monitor exit followed by quit with confirmation, we get the gdb
	prompt back, requiring us to do quit once more:
	...
	(gdb) monitor exit
	(gdb) quit
	A debugging session is active.

	        Inferior 1 [process 16944] will be killed.

	Quit anyway? (y or n) y
	Remote connection closed
	(gdb) quit
	$
	...

	So, the first quit didn't quit.  This happens as follows:
	- quit_command calls query_if_trace_running
	- a TARGET_CLOSE_ERROR is thrown
	- it's caught in remote_target::get_trace_status, but then
	  rethrown because it's TARGET_CLOSE_ERROR
	- catch_command_errors catches the error, at which point the quit command
	  has been aborted.

	The TARGET_CLOSE_ERROR is defined as:
	...
	  /* Target throwing an error has been closed.  Current command should be
	     aborted as the inferior state is no longer valid.  */
	  TARGET_CLOSE_ERROR,
	...
	so in a way this is expected behaviour.  But aborting quit because the inferior
	state (which we've already confirmed we're not interested in) is no longer
	valid, and having to type quit again seems pointless.

	Furthermore, the purpose of not catching errors thrown by
	query_if_trace_running as per commit 2f9d54cfcef ("make -gdb-exit call
	disconnect_tracing too, and don't lose history if the target errors on
	"quit""), was to make sure that error (_("Not confirmed.") had effect.

	Fix this in quit_command by catching only the TARGET_CLOSE_ERROR exception
	during query_if_trace_running and reporting it:
	...
	(gdb) monitor exit
	(gdb) quit
	A debugging session is active.

	        Inferior 1 [process 19219] will be killed.

	Quit anyway? (y or n) y
	Remote connection closed
	$
	...

	sim: mips: call Unpredictable instead of setting bogus values [PR sim/29276]
	The intention of this code seems to be to indicate that this insn
	should not be used and produces undefined behavior, so instead of
	setting registers to bogus values, call Unpredictable.  This fixes
	build warnings due to 32-bit/64-bit type conversions, and outputs

	gdb: link executables with libtool
	This patch changes the GDB build system in order to use libtool to
	link the several built executables.  This makes it possible to refer
	to libtool libraries (.la files) in CLIBS.

	As an application of the above,

	  BFD              now refers to ../libbfd/libbfd.la
	  OPCODES          now refers to ../opcodes/libopcodes.la
	  LIBBACKTRACE_LIB now refers to ../libbacktrace/libbacktrace.la
	  LIBCTF           now refers to ../libctf/libctf.la

	NOTE1: The addition of libtool adds a few new configure-time options
	       to GDB.  Among these, --enable-shared and --disable-shared, which were
	       previously ignored.  Now GDB shall honor these options when linking,
	       picking up the right version of the referred libtool libraries
	       automagically.

	NOTE2: I have not tested the insight build.

	NOTE3: For regenerating configure I used an environment with Autoconf
	       2.69 and Automake 1.15.1.  This should match the previously
	       used version as announced in the configure script.

	NOTE4: Now the installed shared objects libbfd.so, libopcodes.so and
	       libctf.so are used by gdb if binutils is installed with
	       --enable-shared.

	Testing performed:

	- --enable-shared and --disable-shared (the default in binutils) work
	  as expected: the linked executables link with the archive or shared
	  libraries transparently.

	- Makefile.in modified for EXEEXT = .exe.  It installs the binaries
	  just fine.  The installed gdb.exe runs fine.

	- Native build regtested in x86_64. No regressions found.

	- Cross build for aarch64-linux-gnu built to exercise
	  program_transform_name and friends.  The installed
	  aarch64-linux-gnu-gdb runs fine.

	Don't explicitly set clone child ptrace options
	linux_handle_extended_wait calls target_post_attach if we're handling
	a PTRACE_EVENT_CLONE, and libthread_db.so isn't active.
	target_post_attach just calls linux_init_ptrace_procfs to set the
	lwp's ptrace options.  However, this is completely unnecessary,
	because, as man ptrace [1] says, options are inherited:

	  "Flags are inherited by new tracees created and "auto-attached" via
	   active PTRACE_O_TRACEFORK, PTRACE_O_TRACEVFORK, or PTRACE_O_TRACECLONE
	   options."

	configure: require libzstd >= 1.4.0
	gas uses ZSTD_compressStream2 which is only available with libzstd >=
	1.4.0, leading to build errors when an older version is installed.

	This patch updates the check libzstd presence to check its version is
	>= 1.4.0. However, since gas seems to be the only component requiring
	such a recent version this may imply that we disable ZSTD support for
	all components although some would still benefit from an older
	version.

	I ran 'autoreconf -f' in all directories containing a configure.ac
	file, using vanilla autoconf-2.69 and automake-1.15.1. I noticed
	several errors from autoheader in readline, as well as warnings in
	intl, but they are unrelated to this patch.

	This should fix some of the buildbots.

	OK for trunk?

	RISC-V: Remove RV32EF conflict
	Despite that the RISC-V ISA Manual version 2.2 prohibited "RV32EF", later
	versions beginning with the version 20190608-Base-Ratified removed this
	restriction.  Because the 'E' extension is still a draft, the author chose
	to *just* remove the conflict (not checking the ISA version).

	Note that, because RV32E is only used with a soft-float calling convention,
	there's no valid official ABI for RV32EF.  It means, even if we can assemble
	a program with -march=rv32ef -mabi=ilp32e, floating-point registers are kept
	in an unmanaged state (outside ABI management).

	The purpose of this commit is to suppress unnecessary errors while parsing
	an ISA string and/or disassembling, not to allow hard-float with RVE.

		* elfxx-riscv.c (riscv_parse_check_conflicts): Accept RV32EF

2022-11-05  Mike Frysinger  <vapier@gentoo.org>

	sim: run: move linking into top-level
	Automake will run each subdir individually before moving on to the next
	one.  This means that the linking phase, a single threaded process, will
	not run in parallel with anything else.  When we have to link ~32 ports,
	that's 32 link steps that don't take advantage of parallel systems.  On
	my really old 4-core system, this cuts a multi-target build from ~60 sec
	to ~30 sec.  We eventually want to move all compile+link steps to this
	common dir anyways, so might as well move linking now for a nice speedup.

	We use noinst_PROGRAMS instead of bin_PROGRAMS because we're taking care
	of the install ourselves rather than letting automake process it.

	sim: build: add uninstall support
	This never worked before, but adding it to the common top-level dir
	is pretty easy to do now that we're unified.

	sim: build: move install steps to the top-level
	We still have to maintain custom install rules due to how we rename
	arch-specific files with an arch prefix in their name, but we can at
	least unify the logic in the common dir.

	sim: cris: move rvdummy linking to top-level
	This is only used by `make check`, so we can move it out of the
	default build too.

	sim: build: add SIM_HW_CFLAGS to top-level build too
	This matches what we do with targets already.

	sim: drop unused SIM_HARDWARE variable
	This hasn't been used since the refactor way back in commit
	f872d0d643968c1101bb8c07b252edd54f626da2 ("Only enable H/W
	on some mips targets."), so punt it.

	sim: adjust sim_hw options style
	We use uppercase for other variables, and are already turning it to
	uppercase in the arch-subdir.mk, so convert it in the configure step.

	sim: ppc: drop unused /dev/zero logic
	Nothing in the tree checks this option, or has checked for decades.
	The pre-cvs-import ChangeLog suggests this was added & removed back
	then, but can't be sure as that history doesn't exist in the VCS.

	sim: ppc: delete unused host bitsize settings
	Nothing checks this define anywhere, so drop all the logic.  We don't
	want this to be a configure option in the first place as all such usage
	should be automatic & following proper types.

	sim: ppc: inline the sim-packages option
	This has only ever had a single option that's enabled by default.
	The objects it adds are pretty small and don't add overhead at
	runtime if it isn't used, so just enable it all the time to make
	the build code simpler.

	The blr instruction is the last instruction in function foo.  The lines
	with .long following the blr instruction need to be ignored.

	This patch adds a new condition to the gdb_test_multiple "disassemble foo"
	test to ignore the lines with the .long.

	The patch has been tested on PowerPC and Intel X86-64.

	opcodes/arm: silence compiler warning about uninitialized variable use
	After this commit:

	  commit 6576bffe6cbbb53c5756b2fccd2593ba69b74cdf
	  Date:   Thu Jul 7 13:43:45 2022 +0100

	      opcodes/arm: add disassembler styling for arm

	Some people were seeing their builds failing with complaints about a
	possible uninitialized variable usage.  I previously fixed an instance
	of this issue in this commit:

	  commit 2df82cd4b459fbc32120e0ad1ce19e26349506fe
	  Date:   Tue Nov 1 10:36:59 2022 +0000

	      opcodes/arm: silence compiler warning about uninitialized variable use

	which did fix the build problems that the sourceware buildbot was
	hitting, however, an additional instance of the same problem was
	brought to my attention, and that is fixed in this commit.

	Where commit 2df82cd4b4 fixed the uninitialized variable problem in
	print_mve_unpredictable, this commit fixes the same problem in
	print_mve_undefined.

	As with the previous commit, I don't believe we could really ever get
	an uninitialized variable usage, based on the current usage of the
	function, so I have just initialized the reason variable to "??".

	Further, some of the source file generation (e.g. .c files, or igen,

	sim: drop -lm from SIM_EXTRA_LIBS
	We have configure tests for this in the top-level configure script
	to link this when necessary, so we don't need to explicitly list it
	for specific ports.

	sim: build: change AC_CHECK_LIB to AC_SEARCH_LIBS
	With more C libraries moving functions entirely into the main -lc,
	change the AC_CHECK_LIB calls to AC_SEARCH_LIBS so we look in there
	first and avoid extra linkage when possible.

	sim: build: drop duplicate $(LIBS) usage
	COMMON_LIBS is set to $(LIBS), and CONFIG_LIBS is set to that plus
	@LIBS@.  This leds to the values being used twice.  Inline the
	CONFIG_LIBS variable without @LIBS@ since it's used only once.

	sim: build: switch to bfd & opcodes libtool linker scripts
	Now that we use libtool to link, we don't need to duplicate all the
	libs that bfd itself uses.  This simplifies the configure & Makefile.

	sim: build: switch to libtool for linking
	The top-level already sets up a libtool script for the host, so use
	that when linking rather than invoking CC directly.  This will also
	happen when we (someday) move the building to pure automake.

	sim: testsuite: fix cris stat3 in diff setups
	This test uses the test itself as an input to stating regular files.
	This gets funky though: when we run check in parallel, the output
	object dir is the subdir that matches the .exp file.  When we run
	with -j1, the output object dir is the sim builddir itself.

	The old test would append argv[0] to find the file, while the new
	test uses basename on it.  Each method works in only one of the
	aforementioned build scenarios.  Rather than complicate this any
	more, switch to a different file that we know will always exist:
	the Makefile.

2022-11-03  Mike Frysinger  <vapier@gentoo.org>

	sim: testsuite: fix cris badarch in multi-target builds
	This test assumes that /bin/sh will never be a CRIS ELF by way of
	assuming that the current bfd cannot load it (since a basic cris
	cross-compiler only understands CRIS ELFs).  In a multi-target
	build though, bfd understands just about every ELF out there, so
	we're able to read the /bin/sh format before failing at a diff
	point in the cris code.

	Let's switch to using / instead since it'll fail for a similar
	reason (at least similar enough for what this test is testing).

	sim: erc32: link sis to run program
	The erc32 sim does a lot itself, including handling of the CLI.  It
	used to provide a run-compatible interface in the pre-nrun days, but
	it was dropped when the old run interface was punted.  Since the old
	commit 465fb143c87076b6416a8d0d5dd79bb016060fe3 ("sim: make nrun the
	default run program"), the erc32 run & sis programs have been the
	same, and erc32 hasn't provide a real run-compatible interface.

	Simplify this by linking the two programs via ln/cp instead of running
	the linking phase twice to produce the same result.  If/when we fix up
	the erc32 port to have a proper run interface, it should be easy to
	split these back apart into real programs.

	Note: the interf.o reference in here is a bit of a misdirect.  Since
	that object is placed into libsim.a, it's never been linked into the
	programs since the linker ignores objects that aren't referenced, and
	only gdb uses those symbols.

	gdb: Fix issue with Clang CLI macros
	Clang up to version 15 (current) adds macros that were defined in the
	command line or by "other means", according to the Dwarf specification,
	after the last DW_MACRO_end_file, instead of before the first
	DW_MACRO_start_file, as the specification dictates.  When GDB reads the
	macros after the last file is closed, the macros never end up "in scope"
	and so we can't print them.  This has been submitted as a bug to Clang
	developers (https://github.com/llvm/llvm-project/issues/54506), and PR
	macros/29034 was opened for GDB to keep track of this.

	Seeing as there is no expected date for it to be fixed, add a workaround
	for all current versions of Clang.  The workaround detects when
	the main file would be closed and if the producer is Clang, and turns
	that operation into a noop, so we keep a reference to the current_file
	as those macros are read.

	A test case was added to confirm the functionality, and the KFAIL for
	running gdb.base/macro-source-path when using clang.

	sim: move common flags to default AM_CPPFLAGS
	Since all host files we compile use these settings, move them out of
	libcommon.a and into the default AM_CPPFLAGS.  This has the effect of
	dropping the custom per-target automake rules.  Currently it saves us
	~150 lines, but since it's about ~8 lines per object, the overhead
	will increase quite a bit as we merge more files into a single build.

	This also changes the object output names, so we have to tweak the
	rules that were pulling in the common objects when linking.

	Prior to commit 1cb0ab18ad24 ("x86/Intel: restrict suffix derivation")
	the Tbyte modifier on the FLDT and FSTPT templates was pointless, as

	nature of LONG_DOUBLE_MNEM_SUFFIX said commit, however, has led to these

	Comparing the sum of the relevant .imm<N> fields against a constant imo

	RISC-V: Fixed the missing $x+arch when adding odd paddings for alignment.

	.option norelax
	.option arch, +c
	.byte   1
	.align  2
	addi    a0, zero, 1

	Assembler adds $d for the odd .byte, and then adds $x+arch for the
	alignment.  Since norelax, riscv_add_odd_padding_symbol will add the
	$d and $x for the odd alignment, but accidently remove the $x+arch because
	it has the same address as $d.  Therefore, we will get the unexpected result
	before applying this patch,

	.byte   1            # $d
	.align  2            # odd alignment, $xrv32ic replaced by $d + $x

	After this patch, the expected result should be,

	.byte   1            # $d
	.align  2            # odd alignment, $xrv32ic replaced by $d + $xrv32ic

	opcodes/arm: silence compiler warning about uninitialized variable use
	The earlier commit:

	  commit 6576bffe6cbbb53c5756b2fccd2593ba69b74cdf
	  Date:   Thu Jul 7 13:43:45 2022 +0100

	      opcodes/arm: add disassembler styling for arm

	was causing a compiler warning about a possible uninitialized variable
	usage within opcodes/arm-dis.c.

	The problem is in print_mve_unpredictable, and relates to the reason
	variable, which is set by a switch table.

	Currently the switch table does cover every valid value, though there
	is no default case.  The variable switched on is passed in as an
	argument to the print_mve_unpredictable function.

	Looking at how print_mve_unpredictable is used, there is only one use,
	the second argument is the one that is used for the switch table,
	looking at how this argument is set, I don't believe it is possible
	for this argument to take an invalid value.

	So, I think the compiler warning is a false positive.  As such, my
	proposed solution is to initialize the reason variable to the string
	"??", this will silence the warning, and the "??" string should never
	end up being printed.

	opcodes/arm: add disassembler styling for arm
	This commit adds disassembler styling for the ARM architecture.

	The ARM disassembler is driven by several instruction tables,
	e.g. cde_opcodes, coprocessor_opcodes, neon_opcodes, etc

	The type for elements in each table can vary, but they all have one
	thing in common, a 'const char *assembler' field.  This field
	contains a string that describes the assembler syntax of the
	instruction.

	Embedded within that assembler syntax are various escape characters,
	prefixed with a '%'.  Here's an example of a very simple instruction
	from the arm_opcodes table:

	  "pld\t%a"

	The '%a' indicates a particular type of operand, the function
	print_insn_arm processes the arm_opcodes table, and includes a switch
	statement that handles the '%a' operand, and takes care of printing
	the correct value for that instruction operand.

	It is worth noting that there are many print_* functions, each
	function handles a single *_opcodes table, and includes its own switch
	statement for operand handling.  As a result, every *_opcodes table
	uses a different mapping for the operand escape sequences.  This means
	that '%a' might print an address for one *_opcodes table, but in a
	different *_opcodes table '%a' might print a register operand.

	Notice as well that in our example above, the instruction mnemonic
	'pld' is embedded within the assembler string.  Some instructions also
	include comments within the assembler string, for example, also from
	the arm_opcodes table:

	  "nop\t\t\t@ (mov r0, r0)"

	here, everything after the '@' is a comment that is displayed at the
	end of the instruction disassembly.

	The next complexity is that the meaning of some escape sequences is
	not necessarily fixed.  Consider these two examples from arm_opcodes:

	  "ldrex%c\tr%12-15d, [%16-19R]"
	  "setpan\t#%9-9d"

	Here, the '%d' escape is used with a bitfield modifier, '%12-15d' in
	the first instruction, and '%9-9d' in the second instruction, but,
	both of these are the '%d' escape.

	However, in the first instruction, the '%d' is used to print a
	register number, notice the 'r' immediately before the '%d'.  In the
	second instruction the '%d' is used to print an immediate, notice the
	'#' just before the '%d'.

	We have two problems here, first, the '%d' needs to know if it should
	use register style or immediate style, and secondly, the 'r' and '#'
	characters also need to be styled appropriately.

	The final thing we must consider is that some escape codes result in
	more than just a single operand being printed, for example, the '%q'
	operand as used in arm_opcodes ends up calling arm_decode_shift, which
	can print a register name, a shift type, and a shift amount, this
	could end up using register, sub-mnemonic, and immediate styles, as
	well as the text style for things like ',' between the different
	parts.

	I propose a three layer approach to adding styling:

	(1) Basic state machine:

	    When we start printing an instruction we should maintain the idea
	    of a 'base_style'.  Every character from the assembler string will
	    be printed using the base_style.

	   The base_style will start as mnemonic, as each instruction starts
	   with an instruction mnemonic.  When we encounter the first '\t'
	   character, the base_style will change to text.  When we encounter
	   the first '@' the base_style will change to comment_start.

	   This simple state machine ensures that for simple instructions the
	   basic parts, except for the operands themselves, will be printed in
	   the correct style.

	(2) Simple operand styling:

	    For operands that only have a single meaning, or which expand to
	    multiple parts, all of which have a consistent meaning, then I
	    will simply update the operand printing code to print the operand
	    with the correct style.  This will cover a large number of the
	    operands, and is the most consistent with how styling has been
	    added to previous architectures.

	(3) New styling syntax in assembler strings:

	    For cases like the '%d' that I describe above, I propose adding a
	    new extension to the assembler syntax.  This extension will allow
	    me to temporarily change the base_style.  Operands like '%d', will
	    then print using the base_style rather than using a fixed style.

	    Here are the two examples from above that use '%d', updated with
	    the new syntax extension:

	      "ldrex%c\t%{R:r%12-15d%}, [%16-19R]"
	      "setpan\t%{I:#%9-9d%}"

	    The syntax has the general form '%{X:....%}' where the 'X'
	    character changes to indicate a different style.  In the first
	    instruction I use '%{R:...%}' to change base_style to the register
	    style, and in the second '%{I:...%}' changes base_style to
	    immediate style.

	    Notice that the 'r' and '#' characters are included within the new
	    style group, this ensures that these characters are printed with
	    the correct style rather than as text.

	    The function decode_base_style maps from character to style.  I've
	    included a character for each style for completeness, though only
	    a small number of styles are currently used.

	I have updated arm-dis.c to the above scheme, and checked all of the
	tests in gas/testsuite/gas/arm/, and the styling looks reasonable.

	There are no regressions on the ARM gas/binutils/ld tests that I can
	see, so I don't believe I've changed the output layout at all.  There
	were two binutils tests for which I needed to force the disassembler
	styling off.

	I can't guarantee that I've not missed some untested corners of the
	disassembler, or that I might have just missed some incorrectly styled
	output when reviewing the test results, but I don't believe I've
	introduced any changes that could break the disassembler - the worst
	should be some aspect is not styled correctly.

2022-11-01  Andrew Burgess  <aburgess@redhat.com>

	opcodes/arm: use '@' consistently for the comment character
	Looking at the ARM disassembler output, every comment seems to start
	with a ';' character, so I assumed this was the correct character to
	start an assembler comment.

	I then spotted a couple of places where there was no ';', but instead,
	just a '@' character.  I thought that this was a case of a missing
	';', and proposed a patch to add the missing ';' characters.

	Turns out I was wrong, '@' is actually the ARM assembler comment
	character, while ';' is the statement separator.  Thus this:

	    nop    ;@ comment

	is two statements, the first is the 'nop' instruction, while the
	second contains no instructions, just the '@ comment' comment text.

	This:

	    nop    @ comment

	is a single 'nop' instruction followed by a comment.  And finally,
	this:

	    nop    ; comment

	is two statements, the first contains the 'nop' instruction, while the
	second contains the instruction 'comment', which obviously isn't
	actually an instruction at all.

	Why this matters is that, in the next commit, I would like to add
	libopcodes syntax styling support for ARM.

	The question then is how should the disassembler style the three cases
	above?

	As '@' is the actual comment start character then clearly the '@' and
	anything after it can be styled as a comment.  But what about ';' in
	the second example?  Style as text?  Style as a comment?

	And the third example is even harder, what about the 'comment' text?
	Style as an instruction mnemonic?  Style as text?  Style as a comment?

	I think the only sensible answer is to move the disassembler to use
	'@' consistently as its comment character, and remove all the uses of
	';'.

	Then, in the next commit, it's obvious what to do.

	There's obviously a *lot* of tests that get updated by this commit,
	the only actual code changes are in opcodes/arm-dis.c.

	Add missing TYPE_CODE_* constants to Python
	A user noticed that TYPE_CODE_FIXED_POINT was not exported by the gdb
	Python layer.  This patch fixes the bug, and prevents future
	occurences of this type of bug.

2022-10-31  Carl Love  <cel@us.ibm.com>

	Remove REPARSE condition to force hardware resource checking when updating watchpoints
	Currently the resource checking is done if REPARSE is true.  The hardware
	watchpoint resource checking in update_watchpoint needs to be redone on
	each call to function update_watchpoints as the value chain may have
	changed.  The number of hardware registers needed for a watchpoint can
	change if the variable being watched changes.  This situation occurs in
	this test when watching variable **global_ptr_ptr.  Initially when the
	watch command is issued, only two addresses need to be watched as
	**global_ptr_ptr has not yet been initialized.  Once the value of
	**global_ptr_ptr is initialized the locations to be tracked increase to
	three addresses.  However, update_watchpoints is not called again with
	REPARSE set to 1 to force the resource checking to be redone.  When the
	test is run on Power 10, an internal gdb error occurs when the PowerPC
	routine tries to setup the three hardware watchpoint address since the hw
	only has two hardware watchpoint registers.  The error occurs because the
	resource checking was not redone in update_watchpoints after
	**global_ptr_ptr changed.

	The following descibes the situation in detail that occurs on Power 10 with
	gdb running on the binary for gdb.base/watchpoint.c.

	1 break func4
	2 run
	3 watch *global_ptr
	4 next      execute source code:   buf[0] = 3;
	5 next      execute source code:   global_ptr = buf;
	6 next      execute source code:   buf[0] = 7;
	7 delete 2  (delete watch *global_ptr)
	8 watch **global_ptr_ptr
	9 next       execute source code:   buf[1] = 5;
	10 next      global_ptr_ptr = &global_ptr;
	11 next      buf[0] = 9;

	In step 8, the the watch **global_ptr_prt command calls update_watchpoint
	in breakpoint.c with REPARSE set to 1.  The function update_watchpoint
	calls can_use_hardware_watchpoint to see if there are enough
	resources available to add the watchpoint since REPARSE is set to 1.  At
	this point, **global_ptr_ptr has not been initialized so only two addresses
	are watched.  The val_chain contains the address for **global_ptr_ptr and 0
	since **global_ptr_ptr has not been initialized.  The update_watchpoint
	updates the breakpoint list as follows:

	  breakpoint 0
	   loc 0: b->address = 0x100009c0
	  breakpoint 1
	   loc 1: b->address = 0x7ffff7f838a0
	  breakpoint 2
	   loc 2: b->address = 0x7ffff7b7fc54
	  breakpoint 3
	   loc 3: b->address = 0x7ffff7a5788c
	  breakpoint 4
	   loc 4: b->address = 0x0         <-- location pointed to by global_ptr_ptr
	   loc 5: b->address = 0x100200b8  <-- global_ptr_ptr watchpoint
	  breakpoint 5
	   loc 6: b->address = 0x7ffff7b7fc54

	In step 10, the next command executes the source code
	global_ptr_ptr = &global_ptr.  This changes the set of locations to be
	watched for the watchpoint **global_ptr_prt.  The list of addresses for the
	breakpoint consist of the address for global_ptr_prt, global_ptr and buf.
	The breakpoint list gets updated by update_watchpoint as follows:

	  breakpoint 0
	   loc 0: b->address = 0x100009c0
	  breakpoint 1
	   loc 1: b->address = 0x7ffff7f838a0
	  breakpoint 2
	   loc 2: b->address = 0x7ffff7b7fc54
	  breakpoint 3
	   loc 3: b->address = 0x7ffff7a5788c
	  breakpoint 4
	   loc 4: b->address = 0x10020050           buf
	   loc 5: b->address = 0x100200b0           watch *global_ptr
	   loc 6: b->address = 0x100200b8           watch **global_ptr_ptr
	  breakpoint 5
	   loc 7: b->address = 0x7ffff7b7fc54
	  breakpoint 6

	However, the hardware resource checking was not redone because
	update_breakpoint was called with REPARSE equal to  0.

	Step 11, execute the third next command.  The function
	ppc_linux_nat_target::low_prepare_to_resume() attempts a ptrace
	call to setup each of the three address for breakpoint 4.  The slot
	value returned for the third ptrace call is -1 indicating an error
	because there are only two hardware watchpoint registers available on
	Power 10.

	This patch removes just the statement "if (reparse)" in function
	update_watchpoint to force the resources to be rechecked on every call to
	the function.  This ensures that any changes to the val_chain resulting
	in needing more resources then available will be caught.

	The patch has been tested on Power 8, Power 10 and X86-64.  Note the patch
	has no effect on Power 9 since hardware watchpoint support is disabled on
	that processor.

	PowerPC, add support for recording pipe2 system call.
	Test gdb.reverse/pipe-reverse.exp fails on Power 10 running the fedora 36
	distro.  The gdb record error message is:

	  Process record and replay target doesn't support syscall number 317.

	System call 317 on PowerPC maps to the pipe2 system call.

	This patch adds support for the missing pipe2 system call for PowerPC.

	Patch fixes the test failure in gdb.reverse/pipe-reverse.exp.

	The patch has been tested on Power 10 with no regression failures.

	x86: minor improvements to optimize_imm() (part III)
	Earlier tidying still missed an opportunity: There's no need for the
	"anyimm" static variable. Instead of using it in the loop to mask
	"allowed" (which is necessary to satisfy operand_type_or()'s assertions)
	simply use "mask", requiring it to be calculated first. That way the
	post-loop masking by "mask" ahead of the operand_type_all_zero() can be
	dropped.

	Fix regression in pointer-to-member printing
	PR c++/29243 points out that "info func" on a certain C++ executable
	will cause an infinite loop in gdb.

	I tracked this down to a bug introduced by commit 6b5a7bc76 ("Handle
	member pointers directly in generic_value_print").  Before this
	commit, the C++ code to print a member pointer would wind up calling
	value_print_scalar_formatted; but afterward it simply calls
	generic_value_print and gets into a loop.

	This patch restores the previous behavior and adds a regression test.

	Fuzzers have found a weakness in the code stashing pool section

	than each index pointing to its own set distinct from other sets),
	it's possible to overflow the space allocated, losing the NULL

	[gdb/testsuite] Use ssh -t in remote-*.exp
	When running test-case gdb.server/multi-ui-errors.exp on target board
	remote-gdbserver-on-localhost.exp, I run into:
	...
	(gdb) PASS: gdb.server/multi-ui-errors.exp: connect to gdbserver
	continue^M
	Continuing.^M
	PASS: gdb.server/multi-ui-errors.exp: continue - extra UI
	Remote debugging from host ::1, port 35466^M
	FAIL: gdb.server/multi-ui-errors.exp: ensure inferior is running
	...

	The problem is that the target board uses ssh -T, which fails to guarantee
	that output from the inferior will be available.

	Fix this by copying proc ${board}_spawn from local-remote-host.exp, which
	ensures using ssh -t.  [ It would be nice to define an ssh base board to
	get rid of the copies, but I'm not addressing that in this commit. ]

	Likewise for target board remote-stdio-gdbserver.exp.

	(gdb) PASS: gdb.server/multi-ui-errors.exp: main UI, prompt after gdbserver dies
	...

	The test-case issues a kill, which results in a "Remote connection closed"
	message and a prompt.

	The problem is that the prompt is not consumed, so the subsequent echo may be
	issued before that prompt, which causes a mismatch when matching the result
	of the echo.

	sim, sim/{m32c,ppc,rl78}: Use getopt_long
	Because of a Libiberty hack, getopt on GNU libc (2.25 or earlier) is
	currently unusable on sim, causing a regression on CentOS 7.

	This is caused as follows:

	1.  If HAVE_DECL_GETOPT is defined (getopt declaration with known prototype
	    is detected while configuration), a declaration of getopt in
	    "include/getopt.h" is suppressed.
	    The author started to define HAVE_DECL_GETOPT in sim with the commit
	    340aa4f6872c ("sim: Check known getopt definition existence").
	2.  GNU libc (2.25 or earlier)'s <unistd.h> includes <getopt.h> with a
	    special purpose macro defined to declare only getopt function but due
	    to include path (not tested while configuration), it causes <unistd.h>
	    to include Libiberty's "include/getopt.h".
	3.  If both 1. and 2. are satisfied, despite that <unistd.h> tries to
	    declare getopt by including <getopt.h>, "include/getopt.h" does not do
	    so, causing getopt function undeclared.

	Getting rid of "include/getopt.h" (e.g. renaming this header file) is the
	best solution to avoid hacking but as a short-term solution, this commit
	replaces getopt with getopt_long under sim/.

2022-10-27  Tom de Vries  <tdevries@suse.de>

	[gdb/testsuite] Fix silent timeouts in gdb.mi/mi-exec-run.exp with remote host
	I noticed that running test-case gdb.mi/mi-exec-run.exp with host board
	local-remote-host.exp takes about 44 seconds.

	I found two silent timeouts responsible for this.

	The first is in mi_gdb_exit, where we have:
	...
	    if { [is_remote host] && [board_info host exists fileid] } {
	        send_gdb "999-gdb-exit\n"
	        gdb_expect 10 {
	            -re "y or n" {
	                send_gdb "y\n"
	                exp_continue
	            }
	            -re "Undefined command.*$gdb_prompt $" {
	                send_gdb "quit\n"
	                exp_continue
	            }
	            -re "DOSEXIT code" { }
	        }
	    }
	...
	so in gdb.log we see:
	...
	999-gdb-exit^M
	999^exit^M
	=thread-exited,id="1",group-id="i1"^M
	=thread-group-exited,id="i1"^M
	...
	after which expect just waits for the timeout.

	Fix this by adding a gdb_expect clause to parse the exit:
	...
	            -re "\r\n999\\^exit\r\n" { }
	...

	Note that we're not parsing the thread-exited/thread-group-exited messages, because
	they may not be present:
	...
	$ gdb -i=mi
	=thread-group-added,id="i1"
	(gdb)
	999-gdb-exit
	999^exit
	$
	...

	After fixing that, we have:
	...
	(gdb) ^M
	saw mi error
	PASS: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: \
	  force-fail=1: run failure detected
	quit^M
	&"quit\n"^M
	...

	What seems to be happening is that default_gdb_exit sends a cli interpreter
	quit command to an mi interpreter, after which again expect just waits for the
	timeout.

	Fix this by adding mi_gdb_exit to the end of the test-case, as in many other
	gdb.mi/*.exp test-cases.

	After these two fixes, the test-case takes about 4 seconds.

	Tested on x86_64-linux.

	[gdb/testsuite] Use remote_exec chmod instead of remote_spawn
	I build gdb using -O2, and ran the testsuite using taskset -c 0, and ran into:
	...
	(gdb) PASS: gdb.server/connect-with-no-symbol-file.exp: sysroot=: \
	  action=delete: setup: adjust sysroot
	builtin_spawn gdbserver --once localhost:2385 /connect-with-no-symbol-file^M
	/bin/bash: connect-with-no-symbol-file: Permission denied^M
	/bin/bash: line 0: exec: connect-with-no-symbol-file: cannot execute: \
	  Permission denied^M
	During startup program exited with code 126.^M
	Exiting^M
	target remote localhost:2385^M
	`connect-with-no-symbol-file' has disappeared; keeping its symbols.^M
	localhost:2385: Connection timed out.^M
	(gdb) FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: \
	  action=delete: connection to GDBserver succeeded
	...

	The expected series of events is (skipping disconnect and detach as I don't
	think they're relevant to the problem):
	- enter scenario "permission"
	- cp $exec.bak $exec
	- gdbserver start with $exec
	- chmod 000 $exec
	- connect to gdbserver
	- enter scenario "delete"
	- cp $exec.bak $exec
	- gdbserver start with $exec
	- delete $exec
	- connect to gdbserver

	The problem is that the chmod is executed using remote_spawn:
	...
	       } elseif { $action == "permission" } {
	         remote_spawn target "chmod 000 $target_exec"
	       }
	...
	without waiting on the resulting spawn id, so we're not sure when the
	chmod will have effect.

	The FAIL we're seeing above is explained by the chmod having effect during the
	delete scenario, after the "cp $exec.bak $exec" and before the "gdbserver
	start with $exec".

	Fix this by using remote_exec instead.

	Likewise, fix a similar case in gdb.mi/mi-exec-run.exp.

	Tested on x86_64-linux.

	gdb/testsuite: fix gdb.guile/scm-parameter.exp "wrong type argument" test pattern for Guile >= 2.2
	Since commit 90319cefe3 ("GDB/Guile: Don't assert that an integer value
	is boolean"), I see:

	    FAIL: gdb.guile/scm-parameter.exp: kind=PARAM_ZINTEGER: test-PARAM_ZINTEGER-param: guile (set-parameter-value! test-PARAM_ZINTEGER-param #:unlimited)
	    FAIL: gdb.guile/scm-parameter.exp: kind=PARAM_ZUINTEGER: test-PARAM_ZUINTEGER-param: guile (set-parameter-value! test-PARAM_ZUINTEGER-param #:unlimited)

	This comes from the fact that GDB outputs this:

	    ERROR: In procedure set-parameter-value!:
	    In procedure gdbscm_set_parameter_value_x: Wrong type argument in position 2 (expecting integer): #:unlimited
	    Error while executing Scheme code.

	while the test expects an additional "ERROR:" on the second line,
	something like this:

	    ERROR: In procedure set-parameter-value!:
	    ERROR: In procedure gdbscm_set_parameter_value_x: Wrong type argument in position 2 (expecting integer): #:unlimited
	    Error while executing Scheme code.

	Guile 2.0 outputs the `ERROR:` on the second line, while later versions
	do not.  Change the pattern to accept both outputs.  This is similar to
	commit 6bbe1a929c6 ("[gdb/testsuite] Fix gdb.guile/scm-breakpoint.exp
	with guile 3.0").

	gdb/arm: Fix M-profile EXC_RETURN
	Arm v8-M Architecture Reference Manual,
	D1.2.95 EXC_RETURN, Exception Return Payload
	describes ES bit:

	"ES, bit [0]
	     Exception Secure. The security domain the exception was taken to.
	     The possible values of this bit are:
	       0 Non-secure.
	       1 Secure"

	arm-tdep.c:3443, arm_m_exception_cache () function tests this bit:

	  exception_domain_is_secure = (bit (lr, 0) == 0);

	The test is negated!

	Later on line 3553, the condition evaluates if an additional state
	context is stacked:

	  /* With the Security extension, the hardware saves R4..R11 too.  */
	  if (tdep->have_sec_ext && secure_stack_used
	      && (!default_callee_register_stacking || exception_domain_is_secure))

	RM, B3.19 Exception entry, context stacking
	reads:
	RPLHM "In a PE with the Security Extension, on taking an exception,
	the PE hardware:
	  ...
	  2. If exception entry requires a transition from Secure state to
	     Non-secure state, the PE hardware extends the stack frame and also
	     saves additional state context."

	So we should test for !exception_domain_is_secure instead of non-negated
	value!
	These two bugs compensate each other so unstacking works correctly.

	But another test of exception_domain_is_secure (negated due to the
	first bug) prevents arm_unwind_secure_frames to work as expected:

	  /* Unwinding from non-secure to secure can trip security
	     measures.  In order to avoid the debugger being
	     intrusive, rely on the user to configure the requested
	     mode.  */
	  if (secure_stack_used && !exception_domain_is_secure
	      && !arm_unwind_secure_frames)

	Test with GNU gdb (GDB) 13.0.50.20221016-git.

	gdb/arm: Terminate frame unwinding in M-profile lockup
	In the lockup state the PC value of the the outer frame is irreversibly
	lost. The other registers are intact so LR likely contains
	PC of some frame next to the outer one, but we cannot analyze
	the nearest outer frame without knowing its PC
	therefore we do not know SP fixup for this frame.

	The frame unwinder possibly gets mad due to the wrong SP value.
	To prevent problems terminate unwinding if PC contains the magic
	value of the lockup state.

	x86-64: Use only one default max-page-size
	On x86-64 the default ELF_MAXPAGESIZE depends on a configure
	option (--disable-separate-code).  Since 9833b775
	("PR28824, relro security issues") we use max-page-size for relro
	alignment (with a short interval, from 31b4d3a ("PR28824, relro
	security issues, x86 keep COMMONPAGESIZE relro") to its revert
	a1faa5ea, where x86-64 only used COMMONPAGESIZE as relro alignment
	target).

	But that means that a linker configured with --disable-separate-code
	behaves different from one configured with --enable-separate-code
	(the default), _even if using "-z {no,}separate-code" option to use
	the non-configured behaviour_ .  In particular it means that when
	configuring with --disable-separate-code the linker will produce
	binaries aligned to 2MB pages on disk, and hence generate 2MB
	executables for a hello world (and even 6MB when linked with
	"-z separate-code").

	Generally we can't have constants that ultimately land in static
	variables be depending on configure options if those only influence
	behaviour that is overridable by command line options.

	So, do away with that, make the default MAXPAGESIZE be 4k (as is default
	for most x86-64 configs anyway, as most people won't configure with
	--disable-separate-code).  If people need more they can use the
	"-z max-page-size" (with would have been required right now for a
	default configure binutils).

	gdb/testsuite: make sure to consume the prompt in gdb.base/unwind-on-each-insn.exp
	This test fails quite reliably for me when ran as:

	    $ taskset -c 1 make check TESTS="gdb.base/unwind-on-each-insn.exp" RUNTESTFLAGS="--target_board=native-gdbserver"

	or more simply:

	    $ make check-read1 TESTS="gdb.base/unwind-on-each-insn.exp"

	The problem is that the gdb_test_multiple call that grabs the frame id
	from "maint print frame-id" does not consume the prompt.  Well, it does
	sometimes due to the trailing .*, but not always.  If the prompt is not
	consumed, the tests that follow get confused:

	    FAIL: gdb.base/unwind-on-each-insn.exp: gdb_breakpoint: set breakpoint at *foo
	    FAIL: gdb.base/unwind-on-each-insn.exp: disassemble foo
	    FAIL: gdb.base/unwind-on-each-insn.exp: get $sp and frame base in foo: get hexadecimal valueof "$sp"
	    ... many more ...

	Use -wrap to make gdb_test_multiple consume the prompt.

	While at it, remove the bit that consumes the command name and do
	exp_continue, it's not really necessary.  And for consistency, do the
	same changes to the gdb_test_multiple that consumes the stack address,
	although that one was fine, it did consume the prompt explicitly.

	Fix the dwarf assembly test-cases by adding the missing .note.GNU-stack in

	Fix the hard-coded test-cases using this command:
	...
	$ for f in $(find gdb/testsuite/gdb.* -name *.S); do

	      echo -e "\t.section\t.note.GNU-stack,\"\",@progbits" >> $f;
	    fi;
	  done
	...

	Likewise for .s files, and gdb/testsuite/lib/my-syscalls.S.

	The idiom for arm seems to be to use %progbits instead, see commit 9a5911c08be
	("gdb/testsuite/gdb.dwarf2: Replace @ with % for ARM compatability"), so
	hand-edit gdb/testsuite/gdb.arch/arm-disp-step.S to use %progbits instead.

	Note that dwarf assembly testcases use %progbits as decided by proc _section.

	RISC-V: Improve link time complexity.
	The riscv port does deletion and symbol table update for each relocation
	while relaxing, so we are moving section bytes and scanning symbol table once
	for each relocation.  Compared to microblaze port, they record the relaxation
	changes into a table, then do the deletion and symbol table update once per
	section, rather than per relocation.  Therefore, they should have better link
	time complexity than us.

	To improve the link time complexity, this patch try to make the deletion in
	linear time.  Compared to record the relaxation changes into a table, we
	replace the unused relocation with R_RISCV_DELETE for the deleted bytes, and
	then resolve them at the end of the section.  Assuming the number of
	R_RISCV_DELETE is m, and the number of symbols is n, the total link complexity
	should be O(m) for moving section bytes, and O(m*n^2) for symbol table update.
	If we record the relaxation changes into the table, and then sort the symbol
	table by values, then probably can reduce the time complexity to O(m*n*log(n))
	for updating symbol table, but it doesn't seem worth it for now.

	bfd/
	    * elfnn-riscv.c (_riscv_relax_delete_bytes): Renamed from

	sim/lm32: fix some missing function declaration warnings
	In the lm32 simulator, I was seeing some warnings about missing
	function declarations.

	The lm32 simulator has a weird header structure, in order to pull in
	the full cpu.h header we need to define WANT_CPU_LM32BF.  This is done
	in some files, but not in others.  Critically, it's not done in some
	files that then use functions declared in cpu.h

	In this commit I added the missing #define so that the full cpu.h can
	be included.

	After doing this there are still a few functions that are used
	undeclared, these functions appear to be missing any declarations at
	all, so I've added some to cpu.h.

	With this done all the warnings when compiling lm32 are resolved for
	both gcc and clang, so I've removed the SIM_WERROR_CFLAGS line from
	Makefile.in, this allows lm32 to build with -Werror.

	sim/ppc: fix for operator precedence warning from clang
	In the ppc simulator, clang was warning about some code like this:

	  busy_ptr->nr_writebacks = 1 + (PPC_ONE_BIT_SET_P(out_vmask)) ? 1 : 2;

	The warning was:

	  operator '?:' has lower precedence than '+'; '+' will be evaluated first

	I suspect that this is not the original authors intention.
	PPC_ONE_BIT_SET_P is going to be 0 or 1, so if we evaluate the '+'
	first, the condition will always be non-zero, so true.  The whole
	expression could then be simplified to just '1', which doesn't make
	much sense.

	I suspect the answer the author was expecting was either 2 or 3.  Why
	they didn't just write:

	  busy_ptr->nr_writebacks = (PPC_ONE_BIT_SET_P(out_vmask)) ? 2 : 3;

	I have no clue, however, to keep the structure of the code unchanged,
	I've updated things to:

	  busy_ptr->nr_writebacks = 1 + (PPC_ONE_BIT_SET_P (out_vmask) ? 1 : 2);

	which silences the warning from clang, and is, I am guessing, what the
	original author intended.

	sim/ppc: initialize a memory buffer in all cases
	In the ppc simulator's do_fstat function, which provides the fstat
	call for the simulator, if the fstat is going to fail then we
	currently write an uninitialized buffer into the simulated target.

	In theory, I think this is fine, we also write the error status into
	the simulated target, so, given that the fstat has failed, the target
	shouldn't be relying on the buffer contents.

	However, writing an uninitialized buffer means we might leak simulator
	private data into the simulated target, which is probably a bad thing.
	Plus it probably makes life easier if something consistent, like all
	zeros, is written rather than random junk, which might look like a
	successful call (except for the error code).

	So, in this commit, I initialize the stat buffer to zero before
	it is potentially used.  If the stat call is not made then the buffer
	will be left initialized as all zeros.

2022-10-21  Tom Tromey  <tromey@adacore.com>

	Fix incorrect .gdb_index with new DWARF scanner
	PR symtab/29694 points out a regression caused by the new DWARF
	scanner when the cc-with-gdb-index target board is used.

	What happens here is that an older version of gdb will make an index
	describing the "A" type as:

	[737] A: 1 [global, type]

	whereas the new gdb says:

	[1008] A: 0 [global, type]

	Here the old one is correct because the A in CU 0 is just a
	declaration without a size:

	 <1><45>: Abbrev Number: 10 (DW_TAG_structure_type)
	    <46>   DW_AT_name        : A
	    <48>   DW_AT_declaration : 1
	    <48>   DW_AT_sibling     : <0x6d>

	This patch fixes the problem by introducing the idea of a "type
	declaration".  I think gdb still needs to recurse into these types,
	searching for methods, but by marking the type itself as a
	declaration, gdb can skip this type during lookups and when writing
	the index.

	Regression tested on x86-64 using the cc-with-gdb-index board.

	Fix crash in value_print_array_elements
	A user noticed that gdb would crash when printing a packed array after
	doing "set lang c".  Packed arrays don't exist in C, but it's
	occasionally useful to print things in C mode when working in a non-C
	language -- this lets you see under the hood a little bit.

	The bug here is that generic value printing does not handle packed
	arrays at all.  This patch fixes the bug by introducing a new function
	to extract a value from a bit offset and width.

	The new function includes a hack to avoid problems with some existing
	test cases when using -fgnat-encodings=all.  Cleaning up this code
	looked difficult, and since "all" is effectively deprecated, I thought
	it made sense to simply work around the problems.

	Fix bug in Ada packed array handling
	A user found a bug where an array of packed arrays was printed

	update_static_array_size does not distinguish between an array of
	packed arrays and a multi-dimensional packed array, and for the
	latter, only the innermost array will end up with a stride.

	This patch fixes the problem by adding a flag to indicate whether a
	given array type is a constituent of a multi-dimensional array.

	gdb/reverse: Fix stepping over recursive functions
	Currently, when using GDB to do reverse debugging, if we try to use the
	command "reverse next" to skip a recursive function, instead of skipping
	all of the recursive calls and stopping in the previous line, we stop at
	the second to last recursive call, and need to manually step backwards
	until we leave the first call.  This is well documented in PR gdb/16678.

	This bug happens because when GDB notices that a reverse step has
	entered into a function, GDB will add a step_resume_breakpoint at the
	start of the function, then single step out of the prologue once that
	breakpoint is hit.  The problem was happening because GDB wouldn't give
	that step_resume_breakpoint a frame-id, so the first time the breakpoint
	was hit, the inferior would be stopped.  This is fixed by giving the
	current frame-id to the breakpoint.

	This commit also changes gdb.reverse/step-reverse.c to contain a
	recursive function and attempt to both, skip it altogether, and to skip
	the second call from inside the first call, as this setup broke a
	previous version of the patch.

2022-10-21  Bruno Larsen  <blarsen@redhat.com>

	Change calculation of frame_id by amd64 epilogue unwinder
	When GDB is stopped at a ret instruction and no debug information is
	available for unwinding, GDB defaults to the amd64 epilogue unwinder, to
	be able to generate a decent backtrace. However, when calculating the
	frame id, the epilogue unwinder generates information as if the return
	instruction was the whole frame.

	This was an issue especially when attempting to reverse debug, as GDB
	would place a step_resume_breakpoint from the epilogue of a function if
	we were to attempt to skip that function, and this breakpoint should
	ideally have the current function's frame_id to avoid other problems
	such as PR record/16678.

	This commit changes the frame_id calculation for the amd64 epilogue,
	so that it is always the same as the dwarf2 unwinder's frame_id.

	It also adds a test to confirm that the frame_id will be the same,
	regardless of using the epilogue unwinder or not, thanks to Andrew
	Burgess.

	gdb/python: break more dependencies between gdbpy_initialize_* functions
	In a later commit in this series I will propose removing all of the
	explicit gdbpy_initialize_* calls from python.c and replace these
	calls with a more generic mechanism.

	One of the side effects of this generic mechanism is that the order in
	which the various Python sub-systems within GDB are initialized is no
	longer guaranteed.

	On the whole I don't think this matters, most of the sub-systems are
	independent of each other, though testing did reveal a few places
	where we did have dependencies, though I don't think those
	dependencies were explicitly documented in comment anywhere.

	This commit is similar to the previous one, and fixes the second
	dependency issue that I found.

	In this case the finish_breakpoint_object_type uses the
	breakpoint_object_type as its tp_base, this means that
	breakpoint_object_type must have been initialized with a call to
	PyType_Ready before finish_breakpoint_object_type can be initialized.

	Previously we depended on the ordering of calls to
	gdbpy_initialize_breakpoints and gdbpy_initialize_finishbreakpoints in
	python.c.

	After this commit a new function gdbpy_breakpoint_init_breakpoint_type
	exists, this function ensures that breakpoint_object_type has been
	initialized, and can be called from any gdbpy_initialize_* function.

	I feel that this change makes the dependency explicit, which I think
	is a good thing.

	There should be no user visible changes after this commit.

	This commit removes the first dependency issue, with this and the next
	commit, all of the implicit inter-sub-system dependencies will be
	replaced by explicit dependencies, which will allow me to, I think,
	clean up how the sub-systems are initialized.

	The dependency is around the py_insn_type.  This type is setup in
	gdbpy_initialize_instruction and used in gdbpy_initialize_record.
	Rather than depend on the calls to these two functions being in a
	particular order, in this commit I propose adding a new function
	py_insn_get_insn_type.  This function will take care of setting up the
	py_insn_type type and calling PyType_Ready.  This helper function can
	be called from gdbpy_initialize_record and
	gdbpy_initialize_instruction, and the py_insn_type will be initialized
	just once.

	To me this is better, the dependency is now really obvious, but also,
	we no longer care in which order gdbpy_initialize_record and
	gdbpy_initialize_instruction are called.

	[gdb/testsuite] Fix gdb.debuginfod/fetch_src_and_symbols.exp with check-read1

	Test stepping within a runtime loader / dynamic linker
	See the remarks in rtld-step.exp for a description of what this
	test is about.

	This test case has been tested using gcc on the following x86-64 Linux
	distributions/releases:

	    Fedora 28
	    Fedora 32
	    Fedora 33
	    Fedora 34
	    Fedora 35
	    Fedora 36
	    Fedora 37
	    rawhide (f38)
	    RHEL 9.1
	    Ubuntu 22.04.1 LTS

	It's also been tested (and found to be working) with
	RUNTESTFLAGS="CC_FOR_TARGET=clang" on all of the above expect for
	Fedora 28.  The (old) version of clang available on F28 did not
	accept the -static-pie option.

	I also tried to make this test work on FreeBSD 13.1.  While I think I
	made significant progress, I was ultimately stymied by this message
	which occurs when attempting to run the main program which has been
	set to use the fake/pretend RTLD as the ELF interpreter:

	ELF interpreter /path/to/rtld-step-rtld not found, error 22

	I have left one of the flags (-static) in place which I believe
	to be needed for FreeBSD (though since I never got it to work, I
	don't know for sure.)  I've also left some declarations needed
	for FreeBSD in rtld-step-rtld.c.  They're currently disabled via
	a #if 0; you'll need to enable them if you want to try to make
	it work on FreeBSD.

	Allow debugging of runtime loader / dynamic linker
	At present, GDB does not allow for the debugging of the runtime loader
	and/or dynamic linker.  Much of the time, this makes sense.  An
	application programmer doesn't normally want to see symbol resolution
	code when stepping into a function that hasn't been resolved yet.

	But someone who wishes to debug the runtime loader / dynamic linker
	might place a breakpoint in that code and then wish to debug it
	as normal.  At the moment, this is not possible.  Attempting to step
	will cause GDB to internally step (and not stop) until code
	unrelated to the dynamic linker is reached.

	This commit makes a minor change to infrun.c which allows the dynamic
	loader / linker to be debugged in the case where a step, next, etc.
	is initiated from within that code.

	While developing this fix, I tried some approaches which weren't quite
	right.  The GDB testusite definitely contains tests which FAIL when
	it's done incorrectly.  (At one point, I saw 17 regressions!) This
	commit has been tested on x86-64 linux with no regressions.

	internal_error: remove need to pass __FILE__/__LINE__
	Currently, every internal_error call must be passed __FILE__/__LINE__
	explicitly, like:

	  internal_error (__FILE__, __LINE__, "foo %d", var);

	The need to pass in explicit __FILE__/__LINE__ is there probably
	because the function predates widespread and portable variadic macros
	availability.  We can use variadic macros nowadays, and in fact, we
	already use them in several places, including the related
	gdb_assert_not_reached.

	So this patch renames the internal_error function to something else,
	and then reimplements internal_error as a variadic macro that expands
	__FILE__/__LINE__ itself.

	The result is that we now should call internal_error like so:

	  internal_error ("foo %d", var);

	Likewise for internal_warning.

	The patch adjusts all calls sites.  99% of the adjustments were done
	with a perl/sed script.

	The non-mechanical changes are in gdbsupport/errors.h,
	gdbsupport/gdb_assert.h, and gdb/gdbarch.py.

	sim/iq2000: silence pointer-sign warnings

	  /tmp/build/sim/../../src/sim/iq2000/iq2000.c:50:54: error: pointer targets in passing argument 3 of ‘sim_read’ differ in signedness [-Werror=pointer-sign]
	     50 |   sim_read (CPU_STATE (current_cpu), CPU2DATA(addr), buf, nr);
	        |                                                      ^~~

	I've silenced these warnings by casting buf to 'unsigned char *'.
	With this change I now see no warnings when compiling iq2000.c, so
	I've removed the line from Makefile.in that disables -Werror.

	Makefile.in was also disabling -Werror when compiling mloop.c,
	however, I'm not seeing any warnings when compiling that file, so I've
	removed the -Werror disable in that case too.

	sim/erc32: avoid dereferencing type-punned pointer warnings
	When building the erc32 simulator I get a few warnings like this:

	  /tmp/build/sim/../../src/sim/erc32/exec.c:1377:21: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
	   1377 |   sregs->fs[rd] = *((float32 *) & ddata[0]);
	        |                    ~^~~~~~~~~~~~~~~~~~~~~~~

	The type of '& ddata[0]' will be 'uint32_t *', which is what triggers
	the warning.

	This commit makes use of memcpy when performing the type-punning,
	which resolves the above warnings.

	With this change, I now see no warnings when compiling exec.c, which
	means that the line in Makefile.in that disables -Werror can be
	removed.

	sim/ppc: mark device_error function as ATTRIBUTE_NORETURN
	The device_error function always ends up calling the error function,
	which is itself marked as ATTRIBUTE_NORETURN, so it makes sense that
	device_error should also be marked ATTRIBUTE_NORETURN.

	Doing this resolves a few warnings from hw_ide.c about possibly
	uninitialized variables - the variables are only uninitialized after
	passing through a call to device_error, which obviously means the
	variables are never really used uninitialized, the simulation will
	terminate with the device_error call.

	sim/cgen: mask uninitialized variable warning in cgen-run.c
	I see an uninitialized variable warning (with gcc 9.3.1) from
	cgen-run.c, like this:

	  /tmp/build/sim/../../src/sim/cris/../common/cgen-run.c: In function ‘sim_resume’:
	  /tmp/build/sim/../../src/sim/cris/../common/cgen-run.c:259:5: warning: ‘engine_fns$’ may be used uninitialized in this function [-Wmaybe-uninitialized]
	    259 |    (* engine_fns[next_cpu_nr]) (cpu);
	        |    ~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
	  /tmp/build/sim/../../src/sim/cris/../common/cgen-run.c:232:14: note: ‘engine_fns$’ was declared here
	    232 |   ENGINE_FN *engine_fns[MAX_NR_PROCESSORS];
	        |              ^~~~~~~~~~

	This is a false positive - we over allocate engine_fn, and then only
	initialize the nr_cpus entries which we will later go on to use.

	However, we can easily silence this warning by initializing the unused
	entries in engine_fns to NULL, this might also help if anyone ever
	looks at engine_fns in a debugger, it should now be obvious which
	entries are in use, and which are not.

	With this change the warning is gone.

	There should be no change in behaviour with this commit.

	gdb/testsuite: avoid temporary file in gdb/testsuite (unittest.exp)
	I spotted that the gdb.gdb/unittest.exp script causes a temporary file
	inserters_extractors-2.txt to be created in build/gdb/testsuite/
	instead of in build/gdb/testsuite/output/gdb.gdb/unittest/.

	This is because some of the 'maint selftest' tests create temporary
	files in GDB's current directory, specifically, the two source files:

	  gdb/unittests/basic_string_view/inserters/wchar_t/2.cc
	  gdb/unittests/basic_string_view/inserters/char/2.cc

	both create a temporary file called inserters_extractors-2.txt, though
	we only run the second of these as part of GDB's selftests.

	I initially proposed just using GDB's 'cd' command in unittest.exp to
	switch to the test output directory before running the selftests,
	however, Pedro pointed out that there was a risk here that, if GDB
	crashed during shutdown, the generated core file would be left in the
	test output directory rather than in the testsuite directory.  As a
	result, our clever core file spotting logic would fail to spot the
	core file and alert the user.

	Instead, I propose this slightly more involved solution.  I've added a
	new with_gdb_cwd directory proc, used like this:

	  with_gdb_cwd $directory {
	    # Tests here...
	  }

	The new proc temporarily switches to $directory and then runs the
	tests within the block.  After running the tests the previous current
	working directory is restored.

	Additionally, after switching back to the previous cwd, we check that
	GDB is still responsive.  This means that if GDB crashed immediately
	prior to restoring the previous directory, and left the core file in
	the wrong place, then the responsiveness check will fail, and a FAIL
	will be emitted, this should be enough to alert the user that
	something has gone wrong.

	With this commit in place the unittest.exp script now leaves its
	temporary file in the test output directory.

	gdb/testsuite: avoid creating files in gdb/testsuite directory
	I spotted that the test gdb.dwarf2/dw2-using-debug-str.exp was
	creating an output file called debug_str_section in the root
	build/gdb/testsuite directory instead of using the
	build/gdb/testsuite/output/gdb.dwarf2/dw2-using-debug-str/ directory.

	This appears to be caused by a missing '$' character.  We setup a
	variable debug_str_section which contains a path within the output
	directory, but then when we build the objcopy command we use
	'debug_str_section' without a '$' prefix, as a result, we create the
	debug_str_section file.

	This commit adds the missing '$', the file is now created in the
	output directory.

	Update tests to use skip_hw_watchpoint_tests to test for HW watchpoint support.
	The hardware watchpoint check has been updated in a couple of recent
	patches.  This patch updates the hardware watchpoint test in the remaining
	gdb tests.

	The issue is the PowerPC processors support hardware watchpoints with the
	exception of Power 9. The hardware watchpoint support is disabled on
	Power 9.  The test skip_hw_watchpoint_tests must be used to correctly
	determine if the PowerPC processor supports hardware watchpoints.

	This patch fixes 6 test failures in test gdb.threads/watchpoint-fork.exp.

	Test gdb.base/watch-vfork.exp runs with can-use-hw-watchpoints set to
	true and false.  When the test is run with can-use-hw-watchpoints set to
	true, gdb just falls back to using software watchpoints.  The
	patch reduces the number of expected passes by 2 since because it now
	only runs once with can-use-hw-watchpoints set to false.

	Test gdb.mi/mi-watch.exp runs the test with argument hw and sw.  If the
	argument is hw and hardware watchpoints are not supported the test exits.
	The number of expected passes is cut in half with the patch as it now only
	runs the test using software breakpoints.  Previously the pass to use
	hardware watchpoints was not skipped and the test actually ran using
	software watchpoints.

	The following tests run the same with and without the patch.  The tests
	are supposed to execute the gdb command "set can-use-hw-watchpoints 0" if
	the processor does not support hardware bwatchpoints.  However the command
	was not being executed and gdb was falling back to using software
	watchpoints since the Power 9 watchpoint resource check fails.  With the
	patch, the tests now execute the command and the test runs using software
	watchpoints as it did previously.  The tests are:

	gdb.base/commands.exp
	gdb.base/cond-eval-mode.exp
	gdb.base/display.exp
	gdb.base/gdb11531.exp
	gdb.base/recurse.exp

	gdb.base/watch-cond-infcall.exp
	gdb.base/watch-cond.exp
	gdb.base/watchpoint-solib.exp
	gdb.base/watchpoints.exp

	The following two tests are not supported on the Power 9 system used to
	test the changes.  The patch does not change the tests results for these
	tests:

	gdb.python/py-breakpoint.exp
	gdb.mi/mi-watch-nonstop.exp

	gdb, solib-svr4: support namespaces in DSO iteration
	When looking up names, GDB needs to stay within one linker namespace to
	find the correct instance in case the same name is provided in more than
	one namespace.

	Modify svr4_iterate_over_objfiles_in_search_order() to stay within the
	namespace of the current_objfile argument.  If no current_objfile is
	provided (i.e. it is nullptr), iterate over objfiles in the initial
	namespace.

	For objfiles that do not have a corresponding so_list to provide the
	namespace, assume that the objfile was loaded into the initial namespace.
	This would cover the main executable objfile (which is indeed loaded into
	the initial namespace) as well as manually added symbol files.

	Expected fails:

	  - gdb.base/non-lazy-array-index.exp: the expression parser may lookup
	    global symbols, which may result in xfers to read auxv for determining
	    the debug base as part of svr4_iterate_over_objfiles_in_search_order().

	  - gdb.server/non-lazy-array-index.exp: symbol lookup may access the
	    target to read AUXV in order to determine the debug base for SVR4
	    linker namespaces.

	Known issues:

	  - get_symbol_address() and get_msymbol_address() search objfiles for a
	    'better' match.  This was introduced by

	        4b610737f02 Handle copy relocations

	    to handle copy relocations but it now causes a wrong address to be
	    read after symbol lookup actually cound the correct symbol.  This can
	    be seen, for example, with gdb.base/dlmopen.exp when compiled with
	    clang.

	  - gnu ifuncs are only looked up in the initial namespace.

	  - lookup_minimal_symbol() and lookup_minimal_symbol_text() directly
	    iterate over objfiles and are not aware of linker namespaces.

	Update elf_gnu_ifunc_resolve_by_cache() and elf_gnu_ifunc_resolve_by_got()
	to use gdbarch_iterate_over_objfiles_in_search_order() in order to
	restrict the objfile traversal to the initial namespace.

	In order to extend this to other namespaces, we'd need to provide context,
	e.g. via an objfile inside that namespace.

	gdb, symtab: inline find_quick_global_symbol_language
	There is only one use of find_quick_global_symbol_language that calls it

	Inline the function as it is probably not correct in the general case
	where we may have multiple instances of global symbols with the same name
	but different languages in different libraries in different linker
	namespaces.

	Further, change the objfiles iteration into a call to
	gdbarch_iterate_over_objfiles_in_search_order, which would only search the
	initial linker namespace, where we expect "main" to be located.

	gdb, python: use gdbarch_iterate_over_objfiles_in_search_order
	The implementation of gdb.lookup_objfile() iterates over all objfiles and
	compares their name or build id to the user-provided search string.

	This will cause problems when supporting linker namespaces as the first
	objfile in any namespace will be found.  Instead, use
	gdbarch_iterate_over_objfiles_in_search_order to only consider the
	namespace of gdb.current_objfile() for the search, which defaults to the
	initial namespace when gdb.current_objfile() is None.

2022-10-18  Markus Metzger  <markus.t.metzger@intel.com>

	gdb, compile: unlink objfile stored in module
	When cleaning up after a compile command, we iterate over all objfiles and
	unlink the first objfile with the same name as the one we compiled.

	Since we already store a pointer to that objfile in the module and use it
	to get the name we're comparing against, there's no reason to iterate, at
	all.  We can simply use that objfile.

	This further avoids potential issues when an objfile with the same name is
	loaded into a different linker namespace.

	This implementation uses the address of a namespace's r_debug object as

	gdbserver: move main_lm handling into caller
	When listing SVR4 shared libraries, special care has to be taken about the

	an attribute of the library-list-svr4 element.

	Move that code from where we enumerate libraries inside a single namespace
	to where we generate the rest of the library-list-svr4 element.  This

	gdb, gdbserver: support dlmopen()
	In glibc, the r_debug structure contains (amongst others) the following
	fields:

	  int r_version:
	    Version number for this protocol.  It should be greater than 0.

	If r_version is 2, struct r_debug is extended to struct r_debug_extended
	with one additional field:

	  struct r_debug_extended *r_next;
	    Link to the next r_debug_extended structure.  Each r_debug_extended
	    structure represents a different namespace.  The first r_debug_extended
	    structure is for the default namespace.

	1. Change solib_svr4_r_map argument to take the debug base.

	Add gdb.base/dlmopen.exp to test this.

	To remain backwards compatible with older gdbserver, we reserve the

	Change .gdb_index de-duplication implementation
	While investigating PR symtab/29179, I found that one Ada test failed

	This patch changes how symbol de-duplication is done, deferring the

	More uses of checked_static_cast
	This patch changes a few more uses of static_cast to use
	checked_static_cast.  In this patch, cast-to-references are converted
	by moving the dereference outside of the cast, as checked_static_cast
	only handles pointers.

	PowerPC se_rfmci and VLE, SPE2 and LSP insns with -many
	I noticed recently that se_rfmci, a VLE mode instruction, was being
	accepted by non-VLE cpus, and also that se_rfmci by itself in a
	section did not cause SHF_PPC_VLE to be set.  ie. both testcases added
	by this patch fail without the changes to tc-ppc.c here.

	Also, VLE, SPE2 and LSP insns were not accepted by the assembler with
	-many nor were SPE2 and LSP being disassembled with -Many.

	zlib-gabi to zstd woes
	So we had a zlib-gabi .debug_info section that increased in size with
	zstd, so much so that it was better to leave the section
	uncompressed.  Things went horribly wrong when the section was read
	again later.  The section was read again off disk using the
	uncompressed size.  So you get the zlib section again with some
	garbage at the end.  Fix that particular problem by setting the
	section flag SEC_IN_MEMORY.  Any future read will get sec->contents.

	Also, if the section is to be left uncompressed, the input
	SHF_COMPRESSED flag needs to be reset otherwise objcopy will copy it
	to output.

	Finally, bfd_convert_section_contents needed a small update to handle
	zstd compressed sections, and I've deleted bfd_cache_section_contents.

		* bfd.c (bfd_convert_section_contents): Handle zstd.
		* compress.c (bfd_compress_section_contents): When section
		contents are uncompressed set SEC_IN_MEMORY flag,
		compress_status to COMRESS_SECTION_NONE, and clear
		SHF_COMPRESSED.  Set SEC_IN_MEMORY for compressed contents.
		(bfd_get_full_section_contents): Don't check section size
		against file size when SEC_IN_MEMORY.
		(bfd_cache_section_contents): Delete function.

	[gdb/testsuite] Fix host board local-remote-host-notty.exp timeouts
	With test-case gdb.server/stop-reply-no-thread-multi.exp and host board
	local-remote-host-notty.exp we occasionally run into a silent out, due to
	getting:
	...
	(gdb) kill^M
	(gdb) The program is not being run.^M
	...
	instead of the expected:
	...
	(gdb) kill^M
	The program is not being run.^M
	(gdb)
	...

	Likewise, we occasionally run into a nonsilent timeout:
	...
	(gdb) disconnect^M
	(gdb) You can't do that when your target is `exec'^M
	FAIL: gdb.server/stop-reply-no-thread.exp: to_disable=Tthread: t_nonstop=on: \
	  disconnect (timeout)
	...

	Typically, this results in the test-case taking more than two minutes to run.

	The problem can be reproduced using just:
	...
	$ ssh -l $USER 127.0.0.1 gdb -q -ex kill
	...

	Note that ssh by default uses -T which disables pseudo-tty allocation (as
	opposed to -t which forces pseudo-tty allocation):
	...
	$ ssh -l $USER 127.0.0.1 -T tty
	not a tty
	$ ssh -l $USER 127.0.0.1 -t tty
	/dev/pts/5
	Connection to 127.0.0.1 closed.
	...
	and according to https://stackoverflow.com/a/63241102 the behaviour we're
	seeing is specific to using '-T'.

	The related host board local-remote-host.exp does use '-t', and the only
	difference between the two boards mentioned is whether editing is on or off.

	Fix this by:
	- moving the content of local-remote-host-notty.exp into
	  local-remote-host.exp
	- consequently, extending the copyright years in local-remote-host.exp
	- including local-remote-host.exp in local-remote-host-notty.exp
	  (making local-remote-host-notty.exp use '-t')
	- adding -iex "set editing off" to GDBFLAGS in local-remote-host-notty.exp

	This results in the test-case taking just 6 seconds to run.

	[gdb/testsuite] Disable styling in host board local-remote-host.exp
	With test-case gdb.server/stop-reply-no-thread.exp and host board
	local-remote-host.exp, I run into:
	...

	(gdb) FAIL: gdb.server/stop-reply-no-thread.exp: to_disable=: t_nonstop=off: \
	  continue to main
	...

	The problem is that styling is enabled, and that is causing a regexp mismatch.

	With native, styling is disabled in default_gdb_init by doing
	'setenv TERM "dumb"', but that only has effect because the build (where we
	execute runtest, and consequently the setenv) and the host (where we execute
	gdb) are the same.  For this host board however, gdb executes on a remote
	host, and the setenv has no effect.

	We could try to make some generic way to set TERM on the host, but for the
	purposes of this test-case it seems sufficient to just add:
	...
	set GDBFLAGS "${GDBFLAGS} -iex \"set style enabled off\""
	...
	so let's go with that for now.

	e200 LSP support
	It has bothered me for a long time that we have disabled LSP (and SPE)
	tests.  Also the LSP test comment indicating there is something wrong
	with get_powerpc_dialect.  I don't think there is.  Decoding of a VLE
	instruction depends on whether the processor is in VLE mode (some
	processors support both VLE and standard PPC) which we flag per
	section with SHF_PPC_VLE for decoding when disassembling.

	Background: Some versions of powerpc e200 have "Lightweight Signal
	Processing" support, examples being e200z215 and e200z425.  As far as
	I can tell, LSP and SPE are mutually exclusive.  This seems to be
	borne out by insn encoding, for example LSP "zvaddih" and SPE "evaddw"
	have the same encoding.  So none of the processor descriptions in
	ppc_opts ought to have both PPC_OPCODE_LSP and PPC_OPCODE_SPE/2, if we
	want disassembly to work.  I also could not find anything to suggest
	that the LSP insns are enabled only in VLE mode, which means the LSP
	insns should not be in vle_opcodes.

	Fix all this by moving the LSP insns to their own table, and add a new
	e200z2 cpu entry with LSP support, removing LSP from -me200z4 and from
	-mvle.  (Yes, I know, as I said above some of the e200z4 processors
	have LSP.  Others have SPE.  It's hard to choose good options.  Think
	of z2 as meaning earlier, z4 as later.)  Also add -mlsp to allow
	adding the LSP insn set.

	[gdb/testsuite] Fix nopie test-cases with target board unix/-fPIE/-pie
	Compilers default to either PIE or no-PIE executables.

	In order to test PIE executables with a compiler that produces non-PIE by
	default, we can use target board unix/-fPIE/-pie, which set the multilib_flags
	of the target board to "-fPIE -pie".

	Likewise, we can use target board unix/-fno-PIE/-no-pie with a compiler that
	produces PIE by default.

	The target board unix/-fno-PIE/-no-pie has a potential problem when compiling
	shared libs, because the multilib_flags will override the attempts of
	gdb_compile_shlib to compile with -fPIC.  This is taken care of by running the
	body of gdb_compile_shlib wrapped in with_PIE_multilib_flags_filtered.

	The target board unix/-fPIE/-pie has a problem with nopie compilations.  The
	current approach is to do the compilation hoping for the best, and if we find
	out that the resulting executable is PIE despite specifying nopie, we error
	out with the standard error message "nopie failed to prevent PIE executable".

	That however does not work for hard-coded assembly nopie test-cases, which will
	just noisily refuse to compile:
	...
	ld: amd64-disp-step0.o: relocation R_X86_64_32S against `.text' can not be \
	  used when making a PIE object; recompile with -fPIE^M
	...

	Fix this in gdb_compile by filtering out the PIE settings in the target board
	multilib_flags when pie or nopie is specified.

	Tested on x86_64-linux.

	Volume II: Privileged Architecture of the RISC-V ISA Manual states that the

	As a workaround, we should add implications from privileged extensions that

	PowerPC, fix gdb.base/watchpoint.exp on Power 9
	Test gdb.base/watchpoint.exp generates 4 test errors on Power 9.  The
	test uses the test [target_info exists gdb,no_hardware_watchpoints] to
	determine if the processor supports hardware watchpoints.  The check
	only examines the processor type to determine if it supports hardware
	watchpoints.

	The PowerPC processors support hardware watchpoints with the
	exception of Power 9. The hardware watchpoint support is disabled on
	Power 9.  The test skip_hw_watchpoint_tests must be used to correctly
	determine if the PowerPC processor supports hardware watchpoints.

	This patch replaces the [target_info exists gdb,no_hardware_watchpoints]
	with the skip_hw_watchpoint_tests_p check.  With the patch, the test runs
	on Power 9 with hardware watchpoint force-disabled.  The test runs on
	all other PowerPC processors with and without hardware watchpoints
	enabled.

	The patch has been tested on Power 9 to verify the test only runs with
	hardware breakpoints disabled.  The patch has been tested on X86-64 with
	no regression failures.  The test fails on Power 10 due to an internal GDB
	error due to resource management.  The resource management issue will be
	addressed in another patch.

	[gdb/testsuite] Fix gdb.dwarf2/macro-source-path.exp with -m32
	With test-case gdb.dwarf2/macro-source-path.exp and target board unix/-m32, I
	run into:
	...
	as: macro-source-path-gcc11-ld238-dw5-filename-641.o: \
	  unsupported relocation type: 0x1^M
	...

	The problem is that we have 64-bit dwarf so the debug_line offset in the
	.debug_macro section is an 8-byte entity, emitted using ".8byte":
	...
	        .section .debug_macro
	.Lcu_macros4:
	        .2byte        5                 /* version */
	        .byte        3                  /* flags */
	        .8byte        .LLlines3         /* debug_line offset */
	...
	but the linker doesn't support 8-byte relocation types on a 32-bit architecture.

	This is similar to what was fixed in commit a5ac8e7fa3b
	("[gdb/testsuite] Fix 64-bit dwarf test-cases with -m32") for for instance
	.debug_abbrev.

	Fix this in the same way, by using _op_offset to emit the debug_line offset.

	Tested on x86_64-linux with native and target board unix/-m32.

	The problem is that the test-cases selects an amd64 .S file based on the check:
	...
	if { [istarget "x86_64-*-linux*"] } {
	...
	which is also true for target board unix/-m32 on x86_64-linux.

	[gdb/testsuite] Fix gdb.mi/mi-disassemble.exp with -m32
	With target board unix/-m32 and test-case gdb.mi/mi-disassemble.exp we have:

	FAIL: gdb.mi/mi-disassemble.exp: byte at 0x8048485 matches
	...
	The test-case passes with native.

	With native we see in gdb.log that variable longest_insn_bytes is:
	...
	Longest instruction at 0x0000000000400549 with bytes '48 8b 05 20 01 00 00'
	...
	and variable split_bytes (added debug puts) ends up as:
	...
	SPLIT_BYTES: 48 8b 05 20 01 00 00
	...

	But with unix/-m32 we have longest_insn_byte:
	...
	Longest instruction at 0x08048481 with bytes '8d 4c 24 04        '
	...
	and split_bytes ends up as:
	...
	SPLIT_BYTES: 8d 4c 24 04 {} {} {} {} {} {} {} {}
	...
	so the trailing whitespace is translated by split to empty bytes, and the
	mismatch FAILs are generated for those.

	Fix this by stripping the whitespace, which makes us end up with a different
	and indeed longer insn:
	...
	Longest instruction at 0x08048492 with bytes 'dd 05 98 85 04 08'

	When running test-case gdb.base/ctf-constvars.exp on openSUSE Tumbleweed (with

	(gdb) FAIL: gdb.base/ctf-constvars.exp: print vox

	There are two causes for this:
	- the linker flags are missing --ctf-variables, so the information for variable
	  vox is missing (reported in PR29468), and
	- the executable contains some dwarf2 due to some linked-in glibc objects,
	  so the ctf info is ignored (reported in PR29160).

	By using:
	- -Wl,--ctf-variable,

	sim/ppc: fixes for arguments to printf style functions
	After the recent series of fixes to mark more functions in the
	simulator with ATTRIBUTE_PRINTF, there were some build failures in the
	ppc sim due, in some cases, to bugs with the arguments being passed,
	and in other cases, the issues were (maybe) less serious, with
	arguments being the wrong size, or type, for the printf format being
	used.

	This commit fixes all of the issues that I ran into.

	In each case I selected the easiest solution to the problem, which is
	usually just casting the argument to the correct type.  If anyone
	later on thinks the print format should change, please feel free to do
	that.  What we have here should keep the simulator basically working
	as it does currently, which is my goal with this commit.

	gdb: fix auxv caching
	There's a flaw in the interaction of the auxv caching and the fact that
	target_auxv_search allows reading auxv from an arbitrary target_ops
	(passed in as a parameter).  This has consequences as explained in this
	thread:

	  https://inbox.sourceware.org/gdb-patches/20220719144542.1478037-1-luis.machado@arm.com/

	In summary, when loading an AArch64 core file with MTE support by
	passing the executable and core file names directly to GDB, we see the
	MTE info:

	    $ ./gdb -nx --data-directory=data-directory -q aarch64-mte-gcore aarch64-mte-gcore.core
	    ...
	    Program terminated with signal SIGSEGV, Segmentation fault
	    Memory tag violation while accessing address 0x0000ffff8ef5e000
	    Allocation tag 0x1
	    Logical tag 0x0.
	    #0  0x0000aaaade3d0b4c in ?? ()
	    (gdb)

	But if we do it as two separate commands (file and core) we don't:

	    $ ./gdb -nx --data-directory=data-directory -q -ex "file aarch64-mte-gcore" -ex "core aarch64-mte-gcore.core"
	    ...
	    Program terminated with signal SIGSEGV, Segmentation fault.
	    #0  0x0000aaaade3d0b4c in ?? ()
	    (gdb)

	The problem with the latter is that auxv data gets improperly cached
	between the two commands.  When executing the file command, auxv gets
	first queried here, when loading the executable:

	Here, target_auxv_search is called on the inferior's target stack.  The
	target stack only contains the exec target, so the query returns empty
	auxv data.  This gets cached for that inferior in `auxv_inferior_data`.

	In its constructor (before it is pushed to the inferior's target stack),
	the core_target needs to identify the right target description from the
	core, and for that asks the gdbarch to read a target description from
	the core file.  Because some implementations of
	gdbarch_core_read_description (such as AArch64's) need to read auxv data
	from the core in order to determine the right target description, the
	core_target passes a pointer to itself, allowing implementations to call
	target_auxv_search it.  However, because we have previously cached
	(empty) auxv data for that inferior, target_auxv_search searched that
	cached (empty) auxv data, not auxv data read from the core.  Remember
	that this data was obtained by reading auxv on the inferior's target
	stack, which only contained an exec target.

	The problem I see is that while target_auxv_search offers the
	flexibility of reading from an arbitrary (passed as an argument) target,
	the caching doesn't do the distinction of which target is being queried,
	and where the cached data came from.  So, you could read auxv from a
	target A, it gets cached, then you try to read auxv from a target B, and
	it returns the cached data from target A.  That sounds wrong.  In our
	case, we expect to read different auxv data from the core target than
	what we have read from the target stack earlier, so it doesn't make
	sense to hit the cache in this case.

	To fix this, I propose splitting the code paths that read auxv data from
	an inferior's target stack and those that read from a passed-in target.
	The code path that reads from the target stack will keep caching,
	whereas the one that reads from a passed-in target won't.  And since,
	searching in auxv data is independent from where this data came from,
	split the "read" part from the "search" part.

	From what I understand, auxv caching was introduced mostly to reduce
	latency on remote connections, when doing many queries.  With the change
	I propose, only the queries done while constructing the core_target
	end up not using cached auxv data.  This is fine, because there are just
	a handful of queries max, done at this point, and reading core files is
	local.

	The changes to auxv functions are:

	 - Introduce 2 target_read_auxv functions.  One reads from an explicit
	   target_ops and doesn't do caching (to be used in
	   gdbarch_core_read_description context).  The other takes no argument,
	   reads from the current inferior's target stack (it looks just like a
	   standard target function wrapper) and does caching.

	   The first target_read_auxv actually replaces get_auxv_inferior_data,
	   since it became a trivial wrapper around it.

	 - Change the existing target_auxv_search to not read auxv data from the
	   target, but to accept it as a parameter (a gdb::byte_vector).  This
	   function doesn't care where the data came from, it just searches in
	   it.  It still needs to take a target_ops and gdbarch to know how to
	   parse auxv entries.

	 - Add a convenience target_auxv_search overload that reads auxv
	   data from the inferior's target stack and searches in it.  This
	   overload is useful to replace the exist target_auxv_search calls that
	   passed the `current_inferior ()->top_target ()` target and keep the
	   call sites short.

	 - Modify parse_auxv to accept a target_ops and gdbarch to use for
	   parsing entries.  Not strictly related to the rest of this change,
	   but it seems like a good change in the context.

	Changes in architecture-specific files (tdep and nat):

	 - In linux-tdep, linux_get_hwcap and linux_get_hwcap2 get split in two,
	   similar to target_auxv_search.  One version receives auxv data,
	   target and arch as parameters.  The other gets everything from the
	   current inferior.  The latter is for convenience, to avoid making
	   call sites too ugly.

	 - Call sites of linux_get_hwcap and linux_get_hwcap2 are adjusted to
	   use either of the new versions.  The call sites in
	   gdbarch_core_read_description context explicitly read auxv data from
	   the passed-in target and call the linux_get_hwcap{,2} function with
	   parameters.  Other call sites use the versions without parameters.

	 - Same idea for arm_fbsd_read_description_auxv.

	 - Call sites of target_auxv_search that passed
	   `current_inferior ()->top_target ()` are changed to use the
	   target_auxv_search overload that works in the current inferior.

	sim: Check known getopt definition existence
	Clang generates a warning if there is a function declaration/definition
	with zero arguments.  Such declarations/definitions without a prototype (an
	argument list) are deprecated forms of indefinite arguments
	("-Wdeprecated-non-prototype").  On the default configuration, it causes a
	build failure (unless "--disable-werror" is specified).

	include/getopt.h defines some getopt function definitions but one of them
	has a form "extern int getopt ();".  If this form is selected in
	include/getopt.h, Clang generates a warning and the build fails by default.

	In really old environments, this getopt definition with no arguments is
	necessary (because the definition may change between environments).
	However, this definition is now a cause of problems on modern environments.

	A good news is, this definition is not always selected (e.g. if used by
	binutils/*.c).  This is because configuration scripts of binutils, gas,
	gprof and ld tries to find known definition of getopt function is used and
	defines HAVE_DECL_GETOPT macro.  If this macro is defined when getopt.h is
	included, a good form of getopt is used and Clang won't generate warnings.

	This commit adds a modified portion of ld/configure.ac to find the known
	getopt definition.  If we could find one (and we *will* in most modern
	environments), we don't need to rely on the deprecated definition.

	[gdb/testsuite] Fix prompt parsing in capture_command_output
	I noticed in capture_command_output that the output of a single command is
	matched using two gdb_test_multiples:
	- the first one matching the echoed command and skipping an optional prefix,
	- the second one matching the output and the prompt.

	This is error-prone, because the first gdb_test_multiple has implicit
	clauses which may consume the prompt.

	The problem is easy to spot with an example.  First consider:
	...
	set output [capture_command_output "print 1" "\\\$1 = "]
	gdb_assert { [string equal $output "1"] }
	...
	for which we get:
	...
	PASS: [string equal $output "1"]
	...

	If we change the prefix string to a no-match, say "1 = ", and update the
	output string match accordingly, we get instead:
	...
	FAIL: capture_command_output for print 1
	FAIL: [string equal $output "\$1 = 1"]
	...

	The first FAIL is produced by the first gdb_test_multiple, consuming the prompt.

	The second gdb_test_multiple then silently times out waiting for another prompt,
	after which the second FAIL is produced.  Note that the timeout is silent
	because the gdb_test_multiple is called with an empty message argument.

	The second FAIL is because capture_command_output returns "", given that all
	the command output was consumed by the first gdb_test_multiple.

	Fix this by rewriting capture_command_output to use only a single
	gdb_test_multiple.

	Tested on x86_64-linux.

	gdb/testsuite: fix race in gdb.base/async-shell.exp
	I see some random failures in this test:

	    FAIL: gdb.base/async-shell.exp: run & (timeout)

	It can be reliably reproduced on a recent enough GNU/Linux with this
	change:

	    diff --git a/gdb/testsuite/lib/gdb.exp b/gdb/testsuite/lib/gdb.exp
	    index 44cc28b30051..2a3c8253ba5a 100644

	    +    sleep 2
	         set result 0
	         set code [catch {gdb_expect $code} string]

	"recent enough" means a system where libpthread.so was merged with
	libc.so, so at least glibc 2.34.

	The problem is that the `run &` command prints some things after the
	prompt:

	    (gdb) [Thread debugging using libthread_db enabled]
	    Using host libthread_db library "/usr/lib/../lib/libthread_db.so.1".

	If expect is quick enough, it will consume only up to the prompt.  But
	if it is slow enough, it will consume those messages at the same time as
	the prompt, in which case the gdb_test used for "run &" won't match.  By
	default, the prompt used by gdb_test uses a `$` to anchor the match at
	the end of the buffer.  If there's anything following the prompt, it
	won't match.

	The diff above adds a delay between sending the command and consuming
	the output, giving GDB more time to output the messages, giving a good
	chance that expect consumes them at the same time as the prompt.

	This is normally handled by using gdb_test_multiple and specifying a
	pattern that ends with "$gdb_prompt", but not a trailing $.  I think
	this is common enough that it deserves its own gdb_test option.
	Therefore, add the -no-anchor-prompt option to gdb_test, and
	gdb_test_no_output for completeness.  Use it in
	gdb.base/async-shell.exp.

	Fix a latent bug in print_wchar
	print_wchar keeps track of when escape sequences are emitted, to force
	an escape sequence if needed by a subsequent character.  For example
	for the string concatenation "\0" "1", gdb will print "\000\061" --
	because printing "\0001" might be confusing.

	However, this code has two errors.  First, this logic is not needed
	for octal escapes, because there is a length limit of 3 for octal
	escapes, and gdb always prints these with "%.3o".  Second, though,
	this *is* needed for hex escapes, because those do not have a length
	limit.

	This patch fixes these problems and adds the appropriate tests.

	gdb: include the base address in in-memory bfd filenames
	The struct target_buffer (in gdb_bfd.c) is used to hold information
	about an in-memory BFD object created by GDB.  For now this mechanism
	is used by GDB when loading information about JIT symfiles.

	This commit updates target_buffer (in gdb_bfd.c) to be more C++ like,
	and, at the same time, adds the base address of the symfile into the
	BFD filename.

	Right now, every in-memory BFD is given the filename "<in-memory>".
	This filename is visible in things like 'maint info symtabs' and
	'maint info line-table'.  If there are multiple in-memory BFD objects
	then it can be hard to match keep track if which BFD is which.  This
	commit changes the name to be "<in-memory@ADDRESS>" where ADDRESS is
	replaced with the base address for where the in-memory symbol file was
	read from.

	As an example of how this is useful, here's the output of 'maint info
	jit' showing a single loaded JIT symfile:

	  (gdb) maintenance info jit
	  jit_code_entry address symfile address    symfile size
	  0x00000000004056b0     0x0000000007000000 17320

	And here's part of the output from 'maint info symtabs':

	  (gdb) maintenance info symtabs
	  ...snip...
	  { objfile <in-memory@0x7000000> ((struct objfile *) 0x5258250)
	    { ((struct compunit_symtab *) 0x4f0afb0)
	      debugformat DWARF 4
	      producer GNU C17 9.3.1 20200408 (Red Hat 9.3.1-2) -mtune=generic -march=x86-64 -g -fno-stack-protector -fpic
	      name jit-elf-solib.c
	      dirname /tmp/binutils-gdb/build/gdb/testsuite
	      blockvector ((struct blockvector *) 0x5477850)
	      user ((struct compunit_symtab *) (null))
	  	{ symtab /tmp/binutils-gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.base/jit-elf-solib.c ((struct symtab *) 0x4f0b030)
	  	  fullname (null)
	  	  linetable ((struct linetable *) 0x5477880)
	  	}
	    }
	  }

	I've added a new test that checks the new in-memory file names are
	generated correctly, and also checks that the in-memory JIT files can
	be dumped back out using 'dump binary memory'.

	gdb: remove filename arg from gdb_bfd_open_from_target_memory
	The filename argument to gdb_bfd_open_from_target_memory was never
	used; this argument had a default value of nullptr, and the only call
	to this function, in jit.c, relied on the default value.

	In the next commit I'm going to make some changes to the
	gdb_bfd_open_from_target_memory function, and, though I could take
	account of a filename parameter, it seems pointless to maintain an
	unused argument.

	gdb/frame: Add reinflation method for frame_info_ptr
	Currently, despite having a smart pointer for frame_infos, GDB may
	attempt to use an invalidated frame_info_ptr, which would cause internal
	errors to happen.  One such example has been documented as PR
	python/28856, that happened when printing frame arguments calls an
	inferior function.

	To avoid failures, the smart wrapper was changed to also cache the frame
	id, so the pointer can be reinflated later.  For this to work, the
	frame-id stuff had to be moved to their own .h file, which is included
	by frame-info.h.

	Frame_id caching is done explicitly using the prepare_reinflate method.
	Caching is done manually so that only the pointers that need to be saved
	will be, and reinflating has to be done manually using the reinflate
	method because the get method and the -> operator must not change
	the internals of the class.  Finally, attempting to reinflate when the
	pointer is being invalidated causes the following assertion errors:

	check_ptrace_stopped_lwp_gone: assertion `lp->stopped` failed.
	get_frame_pc: Assertion `frame->next != NULL` failed.

	As for performance concerns, my personal testing with `time make
	chec-perf GDB_PERFTEST_MODE=run` showed an actual reduction of around
	10% of time running.

	This commit also adds a testcase that exercises the python/28856 bug with
	7 different triggers, run, continue, step, backtrace, finish, up and down.
	Some of them can seem to be testing the same thing twice, but since this
	test relies on stale pointers, there is always a chance that GDB got lucky
	when testing, so better to test extra.

	Regression tested on x86_64, using both gcc and clang.

	Change GDB to use frame_info_ptr
	This changes GDB to use frame_info_ptr instead of frame_info *

	sed 's/struct frame_info \*/frame_info_ptr /g' - which left some

	sed 's/\<frame_info \*/frame_info_ptr /g'
	sed 's/frame_info_ptr $/frame_info_ptr/g' - used to remove whitespace
	    problems.

	The changed files were then manually checked and some 'sed' changes
	undone, some constructors and some gets were added, according to what

	This adds frame_info_ptr, a smart pointer class.  Every instance of

	gdb/testsuite: use 'end' at the end of python blocks
	Within the testsuite, use the keyword 'end' to terminate blocks of
	Python code being sent to GDB, rather than sending \004.  I could only
	find three instances of this, all in tests that I originally wrote.  I
	have no memory of there being any special reason why I used \004
	instead of 'end' - I assume I copied this from somewhere else that has
	since changed.

	Non of the tests being changed here are specifically about whether
	\004 can be used to terminate a Python block, so I think switching to
	the more standard 'end' keyword is the right choice.

	[gdb/testsuite] Fix silent fail in gdb.server/connect-with-no-symbol-file.exp
	With native and target boards native-gdbserver, remote-gdbserver-on-localhost and
	remote-stdio-gdbserver I have for gdb.server/connect-with-no-symbol-file.exp:
	...
	 # of expected passes            8
	...
	but with native-extended-gdbserver I have instead:
	...
	 # of expected passes            8
	 # of unexpected failures        4
	...

	The extra FAILs are of the form:
	...
	(gdb) detach^M
	Detaching from pid process 28985^M
	[Inferior 1 (process 28985) detached]^M
	(gdb) FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: \
	  action=permission: connection to GDBserver succeeded
	...
	and are due to the fact that the actual gdb output doesn't match the regexp:
	...
	    gdb_test "detach" \
	       ".*Detaching from program: , process.*Ending remote debugging.*" \
	       "connection to GDBserver succeeded"
	...

	With native, the actual gdb output is:
	...

	Ending remote debugging.^M
	[Inferior 1 (process 29657) detached]^M
	(gdb) Remote debugging from host ::1, port 51028^M
	...
	and because the regexp doesn't match, it triggers an implicit clause for
	"Ending remote debugging" in gdb_test_multiple, which has the consequence
	that the FAIL is silent.

	Fix:
	- the regexp by making it less strict
	- the silent fail by rewriting into a gdb_test_multiple, and adding an
	  explicit fail clause.

	PR29653, objcopy/strip: fuzzed small input file induces large output file
	_bfd_check_format functions should not print errors or warnings if

	gdb/arm: Handle lazy FPU state preservation
	Read LSPEN, ASPEN and LSPACT bits from FPCCR and use them together
	with FPCAR to identify if lazy FPU state preservation is active for
	the current frame.  See "Lazy context save of FP state", in B1.5.7,
	also ARM AN298, supported by Cortex-M4F architecture for details on
	lazy FPU register stacking.  The same conditions are valid for other
	Cortex-M cores with FPU.

	This patch has been verified on a STM32F4-Discovery board by:
	a) writing a non-zero value (lets use 0x1122334455667788 as an
	   example) to all the D-registers in the main function
	b) configured the SysTick to fire
	c) in the SysTick_Handler, write some other value (lets use
	   0x0022446688aaccee as an example) to one of the D-registers (D0 as
	   an example) and then do "SVC #0"
	d) in the SVC_Handler, write some other value (lets use
	   0x0099aabbccddeeff) to one of the D-registers (D0 as an example)

	In GDB, suspend the execution in the SVC_Handler function and compare
	the value of the D-registers for the SVC_handler frame and the
	SysTick_Handler frame.  With the patch, the value of the modified
	D-register (D0) should be the new value (0x009..eff) on the
	SVC_Handler frame, and the intermediate value (0x002..cee) for the
	SysTick_Handler frame.  Now compare the D-register value for the
	SysTick_Handler frame and the main frame.  The main frame should
	have the initial value (0x112..788).

	RISC-V: Fix T-Head immediate types on printing
	This commit fixes two minor typing-related issues for
	T-Head immediate operands.

	1.  A signed type must be specified when printing with %i.
	2.  unsigned/signed int is not portable enough for max 32-bit immediates.
	    Instead, we should use unsigned/signed long.
	    The format string is changed accordingly.

	[AArch64] Fix pseudo-register numbering in the presence of unexpected additional registers
	When using AArch64 GDB with the QEMU debugging stub (in user mode), we get
	additional system registers that GDB doesn't particularly care about, so
	it doesn't number those explicitly.

	But given the pseudo-register numbers are above the number of real registers,
	we need to setup/account for the real registers first before going ahead and
	numbering the pseudo-registers.  This has to happen at the end of
	aarch64_gdbarch_init, after the call to tdesc_use_registers, as that
	updates the total number of real registers.

	This is in preparation to supporting pointer authentication for bare metal

	Improve GDB's baseclass detection with typedefs
	When a class inherits from a typedef'd baseclass, GDB may be unable to
	find the baseclass if the user is not using the typedef'd name, as is
	tested on gdb.cp/virtbase2.exp; the reason that test case is working
	under gcc is that the dwarf generated by gcc links the class to the
	original definition of the baseclass, not to the typedef.  If the
	inheritance is linked to the typedef, such as how clang does it,
	gdb.cp/virtbase2.exp starts failing.

	This can also be seen in gdb.cp/impl-this.exp, when attempting to print
	D::Bint::i, and GDB not being able to find the baseclass Bint.

	This happens because searching for baseclasses only uses the macro
	TYPE_BASECLASS_NAME, which returns the typedef'd name. However, we can't
	switch that macro to checking for typedefs, otherwise we wouldn't be
	able to find the typedef'd name anymore. This is fixed by searching for
	members or baseclasses by name, we check both the saved name and the
	name after checking for typedefs.

	This also fixes said long-standing bug in gdb.cp/impl-this.exp when the
	compiler adds information about typedefs in the debuginfo.

	For a while, I didn't spot that DejaGnu had failed at all, I saw the
	115 passes, and thought everything had run correctly - though I was
	puzzled that make was reporting an error.

	What happens is that in gdb/testsuite/Makefile, in the check-single
	rule, we first run DejaGnu, then run the dg-add-core-file-count.sh
	script, and finally, we use sed to extract the results from the
	gdb.sum file.

	In my case, with the invalid test name, DejaGnu fails, but the
	following steps are still run, the final result, the 115 passes, is
	then extracted from the pre-existing gdb.sum file.

	If I use 'make -jN' then the 'check-parallel' rule, rather than the
	'check-single' rule is used.  In this case the behaviour is slightly
	different, the tail end of the output now looks like this:

	  No matching tests found.

	Rather than DejaGnu failing, we now get a nice 'No matching tests
	found' message, followed by some other noise.  This other noise is
	first `find` failing, followed by the dg-extract-results.py script
	failing.

	What happens here is that, in the check-parallel rule, the outputs
	directory is deleted before DejaGnu is invoked.  Then we try to run
	all the tests, and finally we use find and dg-extract-results.py to
	combine all the separate .sun and .log files together.  However, if
	there are no tests run then the outputs/ directory is never created,
	so the find command and consequently the dg-extract-results.py script,
	fail.

	This commit aims to fix the following issues:

	 (1) For check-single and check-parallel rules, don't run any of the
	 post-processing steps if DejaGnu failed to run.  This will avoid all
	 the noise after the initial failure of DejaGnu,

	 (2) For check-single ensure that we don't accidentally report
	 previous results, this is related to the above, but is worth calling
	 out as a separate point, and

	 (3) For check-single, print the 'No matching tests found' message
	 just like we do for a parallel test run.  This makes the parallel and
	 non-parallel testing behaviour more similar, and I think is clearer
	 than the current 'Illegal Argument' error message.

	Points (1) and (2) will be handled by moving the post processing steps
	inside an if block within the recipe.  For check-single I propose
	deleting the gdb.sum and gdb.log files before running DejaGnu, this is
	similar (I think) to how we delete the outputs/ directory in the
	check-parallel rule.

	For point (3) I plan to split the check-single rule in two, the
	existing check-single will be renamed do-check-single, then a new
	check-single rule will be added.  The new check-single rule can either
	depend on the new do-check-single, or will ensure the 'No matching
	tests found' message is printed when appropriate.

	gdb/disasm: better intel flavour disassembly styling with Pygments
	This commit was inspired by this stackoverflow post:

	  https://stackoverflow.com/questions/73491793/why-is-there-a-%C2%B1-in-lea-rax-rip-%C2%B1-0xeb3

	One of the comments helpfully links to this Python test case:

	  from pygments import formatters, lexers, highlight

	  def colorize_disasm(content, gdbarch):
	      try:
	          lexer = lexers.get_lexer_by_name("asm")
	          formatter = formatters.TerminalFormatter()
	          return highlight(content, lexer, formatter).rstrip().encode()
	      except:
	          return None

	  print(colorize_disasm("lea [rip+0x211]  # COMMENT", None).decode())

	Run the test case and you should see that the '+' character is
	underlined, and could be confused with a combined +/- symbol.

	What's happening is that Pygments is failing to parse the input text,
	and the '+' is actually being marked in the error style.  The error
	style is red and underlined.

	It is worth noting that the assembly instruction being disassembled
	here is an x86-64 instruction in the 'intel' disassembly style, rather
	than the default att style.  Clearly the Pygments module expects the
	att syntax by default.

	If we change the test case to this:

	  from pygments import formatters, lexers, highlight

	  def colorize_disasm(content, gdbarch):
	      try:
	          lexer = lexers.get_lexer_by_name("asm")
	          lexer.add_filter('raiseonerror')
	          formatter = formatters.TerminalFormatter()
	          return highlight(content, lexer, formatter).rstrip().encode()
	      except:
	          return None

	  res = colorize_disasm("lea rax,[rip+0xeb3] # COMMENT", None)
	  if res:
	      print(res.decode())
	  else:
	      print("No result!")

	Here I've added the call: lexer.add_filter('raiseonerror'), and I am
	now checking to see if the result is None or not.  Running this and
	the test now print 'No result!' - instead of styling the '+' in the
	error style, we instead give up on the styling attempt.

	There are two things we need to fix relating to this disassembly
	text.  First, Pygments is expecting att style disassembly, not the
	intel style that this example uses.  Fortunately, Pygments also
	supports the intel style, all we need to do is use the 'nasm' lexer
	instead of the 'asm' lexer.

	However, this leads to the second problem; in our disassembler line we
	have '# COMMENT'.  The "official" Intel disassembler style uses ';'
	for its comment character, however, gas and libopcodes use '#' as the
	comment character, as gas uses ';' for an instruction separator.

	Unfortunately, Pygments expects ';' as the comment character, and
	treats '#' as an error, which means, with the addition of the
	'raiseonerror' filter, that any line containing a '#' comment, will
	not get styled correctly.

	However, as the i386 disassembler never produces a '#' character other
	than for comments, we can easily "fix" Pygments parsing of the
	disassembly line.  This is done by creating a filter.  This filter
	looks for an Error token with the value '#', we then change this into
	a comment token.  Every token after this (until the end of the line)
	is also converted into a comment.

	In this commit I do the following:

	  1. Check the 'disassembly-flavor' setting and select between the
	  'asm' and 'nasm' lexers based on the setting.  If the setting is not
	  available then the 'asm' lexer is used by default,

	  2. Use "add_filter('raiseonerror')" to ensure that the formatted
	  output will not include any error text, which would be underlined,
	  and might be confusing,

	  3. If the 'nasm' lexer is selected, then add an additional filter
	  that will format '#' and all other text on the line, as a comment,
	  and

	  4. If Pygments throws an exception, instead of returning None,
	  return the original, unmodified content.  This will mean that this
	  one instruction is printed without styling, but GDB will continue to
	  call into the Python code to style later instructions.

	I haven't included a test specifically for the above error case,
	though I have manually check that the above case now styles
	correctly (with no underline).  The existing style tests check that
	the disassembler styling still works though, so I know I've not
	generally broken things.

	One final thought I have after looking at this issue is that I wonder
	now if using Pygments for styling disassembly from every architecture
	is actually a good idea?

	Clearly, the 'asm' lexer is OK with att style x86-64, but not OK with
	intel style x86-64, so who knows how well it will handle other random
	architectures?

	When I first added this feature I tested it against some random
	RISC-V, ARM, and X86-64 (att style) code, and it seemed fine, but I
	never tried to make an exhaustive check of all instructions, so its
	quite possible that there are corner cases where things are styled
	incorrectly.

	With the above changes I think that things should be a bit better
	now.  If a particular instruction doesn't parse correctly then our
	Pygments based styling code will just not style that one instruction.
	This is combined with the fact that many architectures are now moving
	to libopcodes based styling, which is much more reliable.

	So, I think it is fine to keep using Pygments as a fallback mechanism
	for styling all architectures, even if we know it might not be perfect
	in all cases.

	gdb: improve disassembler styling when Pygments raises an exception
	While working on another issue relating to GDB's use of the Python
	Pygments package for disassembly styling I noticed an issue in the
	case where the Pygments package raises an exception.

	The intention of the current code is that, should the Pygments package
	raise an exception, GDB will disable future attempts to call into the
	Pygments code.  This was intended to prevent repeated errors during
	disassembly if, for some reason, the Pygments code isn't working.

	Since the Pygments based styling was added, GDB now supports
	disassembly styling using libopcodes, but this is only available for
	some architectures.  For architectures not covered by libopcodes
	Pygments is still the only option.

	What I observed is that, if I disable the libopcodes styling, then
	setup GDB so that the Pygments based styling code will indicate an
	error (by returning None), GDB does, as expected, stop using the
	Pygments based styling.  However, the libopcodes based styling will
	instead be used, despite this feature having been disabled.

	The problem is that the disassembler output is produced into a
	string_file buffer.  When we are using Pygments, this buffer is
	created without styling support.  However, when Pygments fails, we
	recreate the buffer with styling support.

	The problem is that we should only recreate the buffer with styling
	support only if libopcodes styling is enabled.  This was an oversight
	in commit:

	  commit 4cbe4ca5da5cd7e1e6331ce11f024bf3c07b9744
	  Date:   Mon Feb 14 14:40:52 2022 +0000

	      gdb: add support for disassembler styling using libopcodes

	This commit:

	  1. Factors out some of the condition checking logic into two new
	  helper functions use_ext_lang_for_styling and
	  use_libopcodes_for_styling,

	  2. Reorders gdb_disassembler::m_buffer and gdb_disassembler::m_dest,
	  this allows these fields to be initialised m_dest first, which means
	  that the new condition checking functions can rely on m_dest being
	  set, even when called from the gdb_disassembler constructor,

	  3. Make use of the new condition checking functions each time
	  m_buffer is initialised,

	  4. Add a new test that forces the Python disassembler styling
	  function to return None, this will cause GDB to disable use of
	  Pygments for styling, and

	  5. When we reinitialise m_buffer, and re-disassemble the
	  instruction, call reset the in-comment flag.  If the instruction
	  being disassembler ends in a comment then the first disassembly pass
	  will have set the in-comment flag to true.  This shouldn't be a
	  problem as we will only be using Pygments, and thus performing a
	  re-disassembly pass, if libopcodes is disabled, so the in-comment
	  flag will never be checked, even if it is set incorrectly.  However,
	  I think that having the flag set correctly is a good thing, even if
	  we don't check it (you never know what future uses might come up).

	gdb/testsuite: extend styling test for libopcodes styling
	This commit extends the gdb.base/style.exp test to cover disassembler
	styling using libopcodes (where available).

	The test will try to enable libopcode based styling, if this
	works (because such styling is available) then some tests are run to
	check that the output is styled, and that the styling can be disabled
	using 'set style disassembler enabled off'.  If libopcodes styling is
	not available on the current architecture then these new tests will be
	skipped.

	I've moved the Python Pygments module check inside the
	test_disable_disassembler_styling function now, so that the test will
	be run even when Python Pygments is not available, this allows the new
	tests discussed above.

	If the Pygments module is not available then the Pygments based tests
	will be skipped just as they were before.

	gdb: update now gdbarch_register_name doesn't return nullptr
	After the previous few commit, gdbarch_register_name no longer returns
	nullptr.  This commit audits all the calls to gdbarch_register_name
	and removes any code that checks the result against nullptr.

	There should be no visible change after this commit.

	gdb: final cleanup of various gdbarch_register_name methods
	Building on the previous commits, this commit goes through the various
	gdbarch_register_name methods and removes all the remaining 'return
	NULL' cases, I claim that these either couldn't be hit, or should be
	returning the empty string.

	In all cases the return of NULL was used if the register number being
	passed to gdbarch_register_name was "invalid", i.e. negative, or
	greater than the total number of declared registers.  I don't believe
	either of these cases can occur, and the previous commit asserts that
	this is the case.  As a result we can simplify the code by removing
	these checks.  In many cases, where the register names are held in an
	array, I was able to add a static assert that the array contains the
	correct number of strings, after that, a direct access into the array
	is fine.

	I don't have any means of testing these changes.

	gdb/csky: remove nullptr return from csky_pseudo_register_name
	Building on the previous commits, in this commit I remove two
	instances of 'return NULL' from csky_pseudo_register_name, and replace
	them with a return of the empty string.

	These two are particularly interesting, and worth pulling into their
	own commit, because these returns of NULL appear to be depended on
	within other parts of the csky code.

	In csky-linux-tdep.c in the register collect/supply code, GDB checks
	for the register name being nullptr in order to decide if a target
	supports a particular feature or not.  I've updated the code to check
	for the empty string.

	I have no way of testing this change.

	gdb: add asserts to gdbarch_register_name
	This commit adds asserts to gdbarch_register_name that validate the
	parameters, and the return value.

	The interesting thing here is that gdbarch_register_name is generated
	by gdbarch.py, and so, to add these asserts, I need to update the
	generation script.

	I've added two new arguments for Functions and Methods (as declared in
	gdbarch-components.py), these arguments are 'param_checks' and
	'result_checks'.  Each of these new arguments can be used to list some
	expressions that are then used within gdb_assert calls in the
	generated code.

	The asserts that validate the API as described in the comment I added
	to gdbarch_register_name a few commits back; the register number
	passed in needs to be a valid cooked register number, and the result
	being returned should not be nullptr.

2022-10-02  Andrew Burgess  <aburgess@redhat.com>

	gdb: check for duplicate register names in selftest
	Building on the previous commit, this commit extends the register_name
	selftest to check for duplicate register names.

	If two registers in the cooked register set (real + pseudo registers)
	have the same name, then this will show up as duplicate registers in
	the 'info all-registers' output, but the user will only be able to
	interact with one copy of the register.

	In this commit I extend the selftest that I added in the previous
	commit to check for duplicate register names, I didn't include this
	functionality in the previous commit because one architecture needed
	fixing, and I wanted to keep those fixes separate from the fixes in
	the previous commit.

	The problematic architecture(s) are powerpc:750 and powerpc:604.  In
	both of these cases the 'dabr' register appears twice, there's a
	definition of dabr in power-oea.xml which is included into both
	powerpc-604.xml and powerpc-750.xml.  Both of these later two xml
	files also define the dabr register.

	I'm hopeful that this change shouldn't break anything, but I don't
	have the ability to actually test this change, however:

	On the gdbserver side, neither powerpc-604.xml nor powerpc-750.xml are
	mentioned in gdbserver/configure.srv, which I think means that
	gdbserver will never use these descriptions, and,

	Within GDB the problematic descriptions are held in the variables
	tdesc_powerpc_604 and tdesc_powerpc_750, which are only mentioned in
	the variants array in rs6000-tdep.c, this is used when looking up a
	description based on the architecture.

	For a native Linux target however, this will not be used as
	ppc_linux_nat_target::read_description exists, which calls
	ppc_linux_match_description, which I don't believe can return either
	of the problematic descriptions.

	This leaves the other native targets, FreeBSD, AIX, etc.  These don't
	appear to override the ::read_description method, so will potentially
	return the problematic descriptions, but, in each case I think the
	::fetch_registers and ::store_registers methods will ignore the dabr
	register, which will leave the register as <unavailable>.

	So, my proposed solution is to just remove the duplicate register from
	each of powerpc-604.xml and powerpc-750.xml, then regenerate the
	corresponding C++ source file.  With this change made, the selftest
	now passes for all architectures.

2022-10-02  Andrew Burgess  <aburgess@redhat.com>

	gdb: add a gdbarch_register_name self test, and fix some architectures
	This commit adds a self-test that checks that gdbarch_register_name
	never returns nullptr for any valid register number.

	Most architectures already met this requirement, there were just 6
	that failed the new selftest, and are updated in this commit.

	Beyond the self-tests I don't have any facilities to test that the
	architectures I've adjusted still work correctly.

	If you review all the various gdbarch_register_name implementations
	then you will see that there are far more architectures that seem like
	they might return nullptr in some situations, e.g. alpha, avr, bpf,
	etc.  This commit doesn't attempt to address these cases as non of
	them are hit during the selftest.  Many of these cases can never be
	hit, for example, in alpha_register_name GDB checks for a register
	number less than zero, this case can't happen and could be changed
	into an assert.

	A later commit in this series will have a general cleanup of all the
	various register_name methods, and remove all references to NULL from
	their code, however, as that commit will be mostly adjusting code that
	is never hit, I want to keep those changes separate.

	The selftest has been tested on x86-64, but I don't have access to
	suitable systems to fully test any of the *-tdep.c code I've changed
	in this commit.

2022-10-02  Andrew Burgess  <aburgess@redhat.com>

	gdb/gdbarch: add a comment to gdbarch_register_name
	After the previous commit, this commit sets out to formalise the API
	for gdbarch_register_name.  Not every architecture is actually in
	compliance with the API I set out here, but I believe that most are.

	I think architectures that don't comply with the API laid out here
	will fail the gdb.base/completion.exp test.

	The claims in the comment are I feel, best demonstrated with the
	asserts in this code:

	  const char *
	  gdbarch_register_name (struct gdbarch *gdbarch, int regnr)
	  {
	    gdb_assert (regnr >= 0);
	    gdb_assert (regnr < gdbarch_num_cooked_regs (gdbarch));

	    const char *name = gdbarch->register_name (gdbarch, regnr);

	    gdb_assert (name != nullptr);

	    return name;
	  }

	Like I said, I don't believe every architecture follows these rules
	right now, which is why I'm not actually adding any asserts.  Instead,
	this commit adds a comment to gdbarch_register_name, this comment is
	where I'd like to get to, rather than where we are right now.

	Subsequent commits will fix all targets to be in compliance with this
	comment, and will even add the asserts shown above to
	gdbarch_register_name.

2022-10-02  Andrew Burgess  <aburgess@redhat.com>

	gdb/riscv: fix failure in gdb.base/completion.exp
	I noticed a test failure in gdb.base/completion.exp for RISC-V on
	a native Linux target, this is the failure:

	  (gdb) FAIL: gdb.base/completion.exp: complete 'info registers '

	The problem is caused by a mismatch in the output of 'maint print
	registers' and the completion list for 'info registers'.  The 'info
	registers' completion list contains less registers than
	expected. Additionally, the list of registers extracted from the
	'maint print registers' list was wrong too, in some cases the test was
	grabbing the register number, rather than a register name,

	Both of these problems have the same root cause, riscv_register_name
	returns nullptr for some registers when it should return an empty
	string.

	The gdbarch_register_name API is not clearly documented anywhere, and
	at first glance it would appear that the function can return either
	nullptr, or an empty string to indicate that a register is not
	available on the current target.  Indeed, there are plenty of places
	in GDB where we compare the output of gdbarch_register_name to both
	nullptr and '\0' in order to see if a register is supported or not,
	and there are plenty of targets that return empty string in some
	cases, and nullptr in others.

	However, the 'info registers' completion code (reg_or_group_completer)
	clearly depends on user_reg_map_regnum_to_name only returning nullptr
	when the passed in regnum is greater than the maximum possible
	register number (i.e. after all physical registers, pseudo-registers,
	and user-registers), this means that gdbarch_register_name should not
	be returning nullptr.

	I did consider "fixing" user_reg_map_regnum_to_name, if
	gdbarch_register_name returns nullptr, I could convert to an empty
	string at this point, but that felt like a real hack, so I discarded
	that plan.

	The next possibility I considered was "fixing" reg_or_group_completer
	to not rely on nullptr to indicate the end marker.  Or rather, I could
	have reg_or_group_completer use gdbarch_num_cooked_regs, we know that
	we should check at least that many register numbers.  Then, once we're
	passed that limit, we keep checking until we hit a nullptr.  This
	would absolutely work, and didn't actually feel that bad, but, it
	still felt a little weird that gdbarch_register_name could return
	nullptr OR the empty string to mean the same thing, so I wondered if
	the "right" solution was to have gdbarch_register_name not return
	nullptr.  With this in mind I tried an experiment:

	I added a self-test that, for each architecture, calls
	gdbarch_register_name for every register number up to the
	gdbarch_num_cooked_regs limit, and checks that the name is not
	nullptr.

	Only a handful of architectures failed this test, RISC-V being one of
	them.

	This seems to suggest that most architectures agree that the correct
	API for gdbarch_register_name is to return an empty string for
	registers that are not supported on the current target, and that
	returning nullptr is really a mistake.

	In this commit I will update the RISC-V target so that GDB no longer
	returns nullptr from riscv_register_name, instead we return the empty
	string.

	In subsequent commits I will add the selftest that I mention above,
	and will fix the targets that fail the selftest.

	With this change the gdb.base/completion.exp test now passes.

	gdb/testsuite: rewrite capture_command_output proc
	I noticed a test failure in gdb.base/completion.exp for RISC-V on a
	native Linux target.  Upon investigation I discovered a couple of
	reasons for the failure, this commit addresses one of them.  A later
	commit will address the other issue.

	The completion.exp test makes use of the capture_command_output proc
	to collect the output of the 'maint print registers' command.  For
	RISC-V this command produces a lot of output.

	Currently the capture_command_output proc tries to collect the
	complete command output in a single expect buffer, and what I see is
	an error caused by the expect buffer becoming full.

	This commit rewrites capture_command_output to make use of
	gdb_test_multiple to collect the command output line at a time, in
	this way we avoid overflowing the expect buffer.

	The capture_command_output proc has some logic for skipping a prefix
	pattern, which is passed in to the proc as an argument.  In order to
	handle this correctly (only matching the prefix at the start of the
	command output), I use two gdb_test_multiple calls, the first spots
	and discards the echoed command and the (optional) prefix pattern, the
	second gdb_test_multiple call then collects the rest of the command
	output line at a time until a prompt is seen.

	There is one slight oddity with the current implementation, which I
	have changed in my rewrite, this does, slightly, change the behaviour
	of the proc.

	The current implementation uses this pattern:

	  -re "[string_to_regexp ${command}]\[\r\n\]+${prefix}(.*)\[\r\n\]+$gdb_prompt $"

	Now a typical command output will look like this:

	  output here\r\n
	  (gdb)

	As the TCL regexp matching is greedy, TCL will try to match as much as
	possible in one part of the pattern before moving on to the next.
	Thus, when this matches against (.*)[\r\n]+, the (.*) will end up
	matching against 'output here\r' and the [\r\n]+ will match '\n' only.

	In short the previous implementation would leave the '\r' on the end
	of the returned text, but not the final trailing '\n'.

	Now clearly I could make a new version of capture_command_output that
	maintained this behaviour, but I couldn't see any reason to do this.
	So, my new implementation drops the final '\r\n' completely, in our
	example above we now return 'output here' with no '\r'.

	This change doesn't seem to affect any of the existing tests, but I
	thought it was worth mentioning.

	gdb/mi: new options for -data-disassemble command
	Now that the disassembler has two different strategies for laying out
	the opcode bytes of an instruction (see /r vs /b for the disassemble
	command), I wanted to add support for this to the MI disassemble
	command.

	Currently the -data-disassemble command takes a single 'mode' value,
	which currently has 6 different values (0 -> 5), 3 of these modes
	relate to opcode display.

	So, clearly I should just add an additional 3 modes to handle the new
	opcode format, right?

	No, I didn't think that was a great idea either.

	So, I wonder, could I adjust the -data-disassemble command in a
	backward compatible way, that would allow GDB to move away from using
	the mode value altogether?

	I think we can.

	In this commit, I propose adding two new options to -data-disassemble,
	these are:

	  --opcodes none|bytes|display
	  --source

	Additionally, I will make the mode optional, and default to mode 0 if
	no mode value is given.  Mode 0 is the simplest, no source code, no
	opcodes disassembly mode.

	The two new options are only valid for mode 0, if they are used with
	any other mode then an error is thrown.

	The --opcodes option can add opcodes to the result, with 'bytes' being
	equivalent to 'disassemble /b' and 'display' being 'disassemble /r'.

	The --source option will enable the /s style source code display, this
	is equivalent to modes 4 and 5.  There is no way, using the new
	command options to get the now deprecated /m style source code
	display, that is mode 1 and 3.

	My hope is that new users of the MI will not use the mode at all, and
	instead will just use the new options to achieve the output they need.
	Existing MI users can continue to use the mode, and will not need to
	be updated to use the new options.

	gdb/mi: some int to bool conversion
	Just some simple int to bool conversion in mi_cmd_disassemble.  There
	should be no user visible changes after this commit.

2022-10-02  Andrew Burgess  <aburgess@redhat.com>

	gdb/doc: update syntax of -data-disassemble command arguments
	The argument documentation for -data-disassemble looks like this:

	   -data-disassemble
	      [ -s @var{start-addr} -e @var{end-addr} ]
	    | [ -a @var{addr} ]
	    | [ -f @var{filename} -l @var{linenum} [ -n @var{lines} ] ]
	    -- @var{mode}

	However, I believe, according to the 'Notation and Terminology'
	section, this means that the there are 3 optional location
	specification argument groups for the command, followed by a
	non-optional '-- mode'.

	However, this is not true, one of the location specifications must be
	given, i.e. we can't choose to give NO location specification, which
	is what the above implies.

	I propose that we change this to instead be:

	   -data-disassemble
	    ( -s @var{start-addr} -e @var{end-addr}
	    | -a @var{addr}
	    | -f @var{filename} -l @var{linenum} [ -n @var{lines} ] )
	    -- @var{mode}

	By placing all the location specifications within '( ... )' we
	indication that these are a group, from which one of the options,
	separated by '|', must be selected.

	However, the 'Notation and Terminology' section only describes two
	uses for parenthesis: '( GROUP )*' and '( GROUP )+', in the first case
	GROUP is repeated zero or more times, and in the second GROUP is
	repeated 1 or more times.

	Neither of those exactly describe what I want, which is GROUP must
	appear exactly once.  I propose to extend 'Notation and Terminology'
	to include '( GROUP )' which means that GROUP should appear exactly
	once.

	This change is important because, in a later commit, I want to add
	additional optional arguments to the -data-disassemble command, and
	things start to get confusing with the original syntax.

	gdb: disassembler opcode display formatting
	This commit changes the format of 'disassemble /r' to match GNU
	objdump.  Specifically, GDB will now display the instruction bytes in
	as 'objdump --wide --disassemble' does.

	Here is an example for RISC-V before this patch:

	  (gdb) disassemble /r 0x0001018e,0x0001019e
	  Dump of assembler code from 0x1018e to 0x1019e:
	     0x0001018e <call_me+66>:     03 26 84 fe     lw      a2,-24(s0)
	     0x00010192 <call_me+70>:     83 25 c4 fe     lw      a1,-20(s0)
	     0x00010196 <call_me+74>:     61 65   lui     a0,0x18
	     0x00010198 <call_me+76>:     13 05 85 6a     addi    a0,a0,1704
	     0x0001019c <call_me+80>:     f1 22   jal     0x10368 <printf>
	  End of assembler dump.

	And here's an example after this patch:

	  (gdb) disassemble /r 0x0001018e,0x0001019e
	  Dump of assembler code from 0x1018e to 0x1019e:
	     0x0001018e <call_me+66>:     fe842603                lw      a2,-24(s0)
	     0x00010192 <call_me+70>:     fec42583                lw      a1,-20(s0)
	     0x00010196 <call_me+74>:     6561                    lui     a0,0x18
	     0x00010198 <call_me+76>:     6a850513                addi    a0,a0,1704
	     0x0001019c <call_me+80>:     22f1                    jal     0x10368 <printf>
	  End of assembler dump.

	There are two differences here.  First, the instruction bytes after
	the patch are grouped based on the size of the instruction, and are
	byte-swapped to little-endian order.

	Second, after the patch, GDB now uses the bytes-per-line hint from
	libopcodes to add whitespace padding after the opcode bytes, this
	means that in most cases the instructions are nicely aligned.

	It is still possible for a very long instruction to intrude into the
	disassembled text space.  The next example is x86-64, before the
	patch:

	  (gdb) disassemble /r main
	  Dump of assembler code for function main:
	     0x0000000000401106 <+0>:     55      push   %rbp
	     0x0000000000401107 <+1>:     48 89 e5        mov    %rsp,%rbp
	     0x000000000040110a <+4>:     c7 87 d8 00 00 00 01 00 00 00   movl   $0x1,0xd8(%rdi)
	     0x0000000000401114 <+14>:    b8 00 00 00 00  mov    $0x0,%eax
	     0x0000000000401119 <+19>:    5d      pop    %rbp
	     0x000000000040111a <+20>:    c3      ret
	  End of assembler dump.

	And after the patch:

	  (gdb) disassemble /r main
	  Dump of assembler code for function main:
	     0x0000000000401106 <+0>:     55                      push   %rbp
	     0x0000000000401107 <+1>:     48 89 e5                mov    %rsp,%rbp
	     0x000000000040110a <+4>:     c7 87 d8 00 00 00 01 00 00 00   movl   $0x1,0xd8(%rdi)
	     0x0000000000401114 <+14>:    b8 00 00 00 00          mov    $0x0,%eax
	     0x0000000000401119 <+19>:    5d                      pop    %rbp
	     0x000000000040111a <+20>:    c3                      ret
	  End of assembler dump.

	Most instructions are aligned, except for the very long instruction.
	Notice too that for x86-64 libopcodes doesn't request that GDB group
	the instruction bytes.  This matches the behaviour of objdump.

	In case the user really wants the old behaviour, I have added a new
	modifier 'disassemble /b', this displays the instruction byte at a
	time.  For x86-64, which never groups instruction bytes, /b and /r are
	equivalent, but for RISC-V, using /b gets the old layout back (except
	that the whitespace for alignment is still present).  Consider our
	original RISC-V example, this time using /b:

	  (gdb) disassemble /b 0x0001018e,0x0001019e
	  Dump of assembler code from 0x1018e to 0x1019e:
	     0x0001018e <call_me+66>:     03 26 84 fe             lw      a2,-24(s0)
	     0x00010192 <call_me+70>:     83 25 c4 fe             lw      a1,-20(s0)
	     0x00010196 <call_me+74>:     61 65                   lui     a0,0x18
	     0x00010198 <call_me+76>:     13 05 85 6a             addi    a0,a0,1704
	     0x0001019c <call_me+80>:     f1 22                   jal     0x10368 <printf>
	  End of assembler dump.

	Obviously, this patch is a potentially significant change to the
	behaviour or /r.  I could have added /b with the new behaviour and
	left /r alone.  However, personally, I feel the new behaviour is
	significantly better than the old, hence, I made /r be what I consider
	the "better" behaviour.

	The reason I prefer the new behaviour is that, when I use /r, I almost
	always want to manually decode the instruction for some reason, and
	having the bytes displayed in "instruction order" rather than memory
	order, just makes this easier.

	The 'record instruction-history' command also takes a /r modifier, and
	has been modified in the same way as disassemble; /r gets the new
	behaviour, and /b has been added to retain the old behaviour.

	Finally, the MI command -data-disassemble, is unchanged in behaviour,
	this command now requests the raw bytes of the instruction, which is
	equivalent to the /b modifier.  This means that the MI output will
	remain backward compatible.

	gdb/disasm: read opcodes bytes with a single read_code call
	This commit reduces the number of times we call read_code when

	gdb_pretty_print_disassembler class, in line with all the other
	buffers that gdb_pretty_print_disassembler needs.  This byte_vector is

	gdb/testsuite: new test for -data-disassemble opcodes format
	Add another test for the output of MI command -data-disassemble.  The
	new check validates the format of the 'opcodes' field, specifically,
	this test checks that the field contains a series of bytes, separated
	by a single space.

	We also check that the bytes are in the correct order, that is, the
	first byte is from the lowest address, and subsequent bytes are from
	increasing addresses.

	The motivation for this test (besides more tests being generally good)
	is that I plan to make changes to how opcode bytes are displayed in
	the disassembler output, and I want to ensure that I don't break any
	existing MI behaviour.

	There should be no user visible changes to GDB after this commit.

	RISC-V: fallout from "re-arrange opcode table for consistent alias handling"
	Several new testcasee have appeared since the submission of said change,
	some of which now also need adjustment.

	RISC-V: fix build after "Add support for arbitrary immediate encoding formats"
	Pre- and post-increment/decrement are side effects, the behavior of
	which is undefined when combined with passing an address of the accessed
	variable in the same function invocation. There's no need for the
	increments here - simply adding 1 achieves the intended effect without
	triggering compiler diagnostics (which are fatal with -Werror).

	objcopy: avoid "shadowing" of remove() function name
	remove() is a standard library function (declared in stdio.h), which
	triggers a "shadows a global declaration" warning with some gcc versions.

	RISC-V: drop stray INSN_ALIAS flags
	FENCE.TSO isn't an alias. ZIP and UNZIP in the long run likely are, but
	presently they aren't. This fixes disassembly of these insns with
	-Mno-aliases.

2022-09-30  Jan Beulich  <jbeulich@suse.com>

	RISC-V: re-arrange opcode table for consistent alias handling
	For disassembly to pick up aliases in favor of underlying insns (helping
	readability in the common case), the aliases need to come ahead of the
	"base" insns. Slightly more code movement is needed because of insns
	with the same name needing to stay next to each other.

	Note that the "rorw" alias entry also has the missing INSN_ALIAS added
	here.

	Clone a few testcases to exercise -Mno-aliases some more, better
	covering the differences between the default and that disassembly mode.

	With the command in the rule merely being "echo", i386-tbl.h won't be

	up-to-date. Use a pattern rule instead to express the multiple targets
	correctly (the &: rule separator is supported only by GNU make 4.3 and
	newer). Note that now, for the opposite case to work (i386-tbl.h is
	up-to-date but i386-init.h is missing), i386-init.h also needs
	mentioning as a dependency somewhere: Add a fake dependency for
	i386-opc.lo ("fake" because i386-opc.c doesn't include that header).

	At the same time use $(AM_V_GEN) in the actual rule, replacing the
	earlier (open-coded) "echo". And while there also drop a duplicate
	dependency of i386-gen.o on i386-opc.h.

	x86: improve match_template()'s diagnostics
	At the example of

		extractps $0, %xmm0, %xmm0
		insertps $0, %xmm0, %eax

	(both having respectively the same mistake of using the wrong kind of
	destination register) it is easy to see that current behavior is far
	from ideal: The former results in "unsupported instruction" for 32-bit
	code simply because the 2nd template we have is a Cpu64 one. Instead we
	should aim at emitting the "best" possible error, which will typically
	be the one where we passed the largest number of checks. Generalize the
	original "specific_error" approach by making it apply to the entire
	matching loop, utilizing that line numbers increase as we pass further
	checks.

	x86/Intel: restrict suffix derivation
	While in some cases deriving an AT&T-style suffix from an Intel syntax
	memory operand size specifier is necessary, in many cases this is not
	only pointless, but has led to the introduction of various workarounds:
	Excessive use of IgnoreSize and NoRex64 as well as the ToDword and
	ToQword attributes. Suppress suffix derivation when we can clearly tell
	that the memory operand's size isn't going to be needed to infer the
	possible need for the low byte/word opcode bit or an operand size prefix
	(0x66 or REX.W).

	As a result ToDword and ToQword can be dropped entirely, plus a fair
	number of IgnoreSize and NoRex64 can also be got rid of. Note that
	IgnoreSize needs to remain on legacy encoded SIMD insns with GPR
	operand, to avoid emitting an operand size prefix in 16-bit mode. (Since
	16-bit code using SIMD insns isn't well tested, clone an existing
	testcase just enough to cover a few insns which are potentially
	problematic but are being touched here.)

	Note that while folding the VCVT{,T}S{S,D}2SI templates, VCVT{,T}SH2SI
	isn't included there. This is to fulfill the request of not allowing L
	and Q suffixes there, despite the inconsistency with VCVT{,T}S{S,D}2SI.

	[gdb/testsuite] Fix gdb.mi/mi-sym-info.exp on openSUSE Tumbleweed
	On openSUSE Tumbleweed, I run into:
	...
	FAIL: gdb.mi/mi-sym-info.exp: List all functions from debug information only
	...

	The problem is in matching this string:
	...
	{name="_start",type="void (void)",description="void _start(void);"}
	...
	using regexp fun_re, which requires a line field:
	...
	set fun_re \
	    "\{line=\"$decimal\",name=${qstr},type=${qstr},description=${qstr}\}"
	...

	Fix this by making the line field optional in fun_re.

	Tested on x86_64-linux.

	RISC-V: Add privileged extensions without instructions/CSRs
	Currently, GNU Binutils does not support following privileged extensions:

	-   'Smepmp'
	-   'Svnapot'
	-   'Svpbmt'

	as they do not provide new CSRs or new instructions ('Smepmp' extends the
	privileged architecture CSRs but does not define the CSR itself).  However,
	adding them might be useful as we no longer have to "filter" ISA strings
	just for toolchains (if full ISA string is given by a vendor, we can
	straightly use it).

	And there's a fact that supports this theory: there's already an
	(unprivileged) extension which does not provide CSRs or instructions (but
	only an architectural guarantee): 'Zkt' (constant timing guarantee for
	certain subset of RISC-V instructions).

	This simple commit simply adds three privileged extensions listed above.

	bfd/ChangeLog:

		* elfxx-riscv.c (riscv_supported_std_s_ext): Add 'Smepmp',
		'Svnapot' and 'Svpbmt' extensions.

	gdb: Remove unused extra_lines variable
	Clang generates a warning if there is a variable that is set but not used

	causes a build failure (unless "--disable-werror" is specified).

	The only extra_lines use in arrange_linetable function is removed on the

	("gdb: change subfile::line_vector to an std::vector").  So, this variable

	[gdb/c++] Print destructor the same for gcc and clang
	Consider the test-case contained in this patch.

	With g++ (7.5.0) we have for "ptype A":
	...
	type = class A {
	  public:
	    int a;

	    A(void);
	    ~A();
	}
	...
	and with clang++ (13.0.1):
	...
	type = class A {
	  public:
	    int a;

	    A(void);
	    ~A(void);
	}
	...
	and we observe that the destructor is printed differently.

	There's a difference in debug info between the two cases: in the clang case,
	there's one artificial parameter, but in the g++ case, there are two, and
	these similar cases are handled differently in cp_type_print_method_args.

	This is due to this slightly convoluted bit of code:
	...
	  i = staticp ? 0 : 1;
	  if (nargs > i)
	    {
	      while (i < nargs)
	        ...
	    }
	  else if (varargs)
	    gdb_printf (stream, "...");
	  else if (language == language_cplus)
	    gdb_printf (stream, "void");
	...

	The purpose of "i = staticp ? 0 : 1" is to skip the printing of the implicit
	this parameter.

	In commit 5f4d1085085 ("c++/8218: Destructors w/arguments"), skipping of other
	artificial parameters was added, but using a different method: rather than
	adjusting the potential loop start, it skips the parameter in the loop.

	The observed difference in printing is explained by whether we enter the loop:
	- in the clang case, the loop is not entered and we print "void".
	- in the gcc case, the loop is entered, and nothing is printed.

	Fix this by rewriting the code to:
	- always enter the loop
	- handle whether arguments need printing in the loop
	- keep track of how many arguments are printed, and
	  use that after the loop to print void etc.
	such that we have the same for both gcc and clang:
	...
	    A(void);
	    ~A(void);
	...

	Note that I consider the discussion of whether we want to print:
	- A(void) / ~A(void), or
	- A() / ~A()
	out-of-scope for this patch.

	Tested on x86_64-linux.

	Constify target_desc declarations
	This patch changes various global target_desc declarations to const, thereby
	correcting a prominent source of ODR violations in PowerPC-related target code.
	The majority of files/changes are mechanical const-ifications accomplished by
	regenerating the C files in features/.

	This also required manually updating mips-linux-tdep.h,  s390-linux-tdep.h,
	nios2-tdep.h, s390-tdep.h, arch/ppc-linux-tdesc.h, arch/ppc-linux-common.c,
	and rs6000-tdep.c.

	Patch tested against the sourceware trybot, and fully regression tested against
	our (Red Hat's) internal  test infrastructure on Rawhide aarch64, s390x, x86_64,
	and powerpcle.

	With this patch, I can finally enable LTO in our GDB package builds. [Tested

	cleanup: Add missing feature/ XML files to Makefile
	This patch adds some missing .xml files to features/Makefile so that when the

	This has demonstrated that there have been several "misses" in regenerating
	files in this directory. Namely, arm-secext.c and sparc{32,64}-solaris.c. For
	the former case, there was what essentially amounts to a typo regarding the
	create feature function's name. In the later case, this file has missed at least
	one important update in July, 2020, when allocate_target_description was
	changed to return a unique pointer.

	Those undefined functions exist in gdb/gcore-elf.c, which is only

	isn't ELF, which is incorrect.

	For the ELF support check, gdb/config.log shows:

	Note how above, in the gcc command line, "-lzstd" appears before

	-lz does.

	This commit fixes it, by moving ZSTD_LIBS from LDFLAGS to LIBS, next
	to -lz, in GDB_AC_CHECK_BFD, and regenerating gdb/configure.

	Since debugging GDB with GDB is (unfortunately) a bit slow, bump the

	gdb/source.c: Fix undefined behaviour dereferencing empty string
	When a source file's dirname is solely made up of directory separators
	we end up trying to dereference the last character of an empty string
	with std::string::back, which results in undefined behaviour. A typical
	use case where this can happen is when the root directory "/" is used as
	a compilation directory.

	With libstdc++.so.6.0.28 we get no out-of-bounds checks and the byte
	preceding the storage of the empty string is returned. The character
	value of this byte depends on heap implementation and usage, but when
	this byte happens to hold the value of the directory separator character
	we go on to call std::string::pop_back on the empty string which results
	in an out_of_range exception which terminates GDB.

	Fix this by using path_join. prepare_path_for_appending ensures that the
	filename component is relative.

	The testsuite has been run before and after the change and no
	regressions were found.

	The problem with warning in elf_object_p
	elfcode.h can emit three warnings in elf_object_p for various things,
	"section extending past end of file", "corrupt string table index",
	and "program header with invalid alignment".  The problem with doing
	this is that the warning can be emitted for multiple possible targets
	as each one is tried.  I was looking at a fuzzer testcase that had an
	object file with 6144 program headers, 5316 of which had invalid
	alignment.  It would be bad enough to get 5316 messages all the same,
	but this object was contained in an archive and resulted in 4975776
	repeats.

	Some trimming can be done by not warning if the bfd is already marked
	read_only, as is done for the "section extending past end of file"
	warning, but that still results in an unacceptable number of
	warnings for object files in archives.  Besides that, it is just wrong
	to warn about a problem detected by a target elf_object_p other than
	the one that actually matches.  At some point we might have more
	target specific warnings.

	So what to do?  One obvious solution is to remove the warnings.
	Another is to poke any warning strings into the target xvec, emitting
	them if that xvec is the final one chosen.  This also has the benefit
	of solving the archive problem.  A warning when recursing into
	_bfd_check_format for the first element of the archive (to find the
	correct target for the archive) will still be on the xvec at the point
	that target is chosen for the archive.  However, target xvecs are
	read-only.  Thus the need for per_xvec_warn to logically extend
	bfd_target with a writable field.  I've made per_xvec_warn one larger
	than bfd_target_vector to provide one place for user code that makes
	private copies of target xvecs.

	gdb/testsuite/tui: start GDB with "set filename-display basename"
	The test gdb.tui/tui-missing-src.exp fails on my CI machine, and I
	concluded that it is caused by the long source directory name:

	  /home/jenkins/workspace/binutils-gdb_master_linuxbuild/platform/jammy-amd64/target_board/unix/src/binutils-gdb

	The long name causes some particular redrawing that doesn't happen for
	shorter directories, and causes a Term::command call to return too
	early.

	This can be reproduced by cloning the binutils-gdb repo in a directory
	with a name similar to the one shown above.

	When running the `Term::command "step"` just before, GDB writes the
	"step", which makes the `wait_for` proc go in the "looking for the
	prompt" mode, to know when the command's execution is complete.  As some
	new output appears, lines that must disappear are deleted using the
	"Delete Line" operation [1] and some new ones are drawn.  The source
	window gets redrawn with the contents of the f2.c file.  Then, GDB
	writes the prompt (at line 23 above), which satisfies `wait_for`, which
	then returns.  The state of the terminal is therefore correct for the
	"check if inside f2" and "f2.c must be displayed in the source window"
	tests.

	In the non-working case, the terminal looks like this by the time the

	What happened is: GDB wrote the "step" command, which make the
	`wait_for` proc go in its "looking for the prompt" mode.  However,
	curses decided to redraw whatever scrolled up to line 17 using some
	standard character insertion operations:

	    +++ Cursor Down (1), cursor: (16, 0) -> (17, 0)
	    +++ Inserting string '('
	    +++   Inserted char '(', cursor: (17, 0) -> (17, 1)
	    +++ Inserted string '(', cursor: (17, 0) -> (17, 1)
	    +++ Inserting string 'g'
	    +++   Inserted char 'g', cursor: (17, 1) -> (17, 2)
	    +++ Inserted string 'g', cursor: (17, 1) -> (17, 2)
	    +++ Inserting string 'd'
	    +++   Inserted char 'd', cursor: (17, 2) -> (17, 3)
	    +++ Inserted string 'd', cursor: (17, 2) -> (17, 3)
	    +++ Inserting string 'b'
	    +++   Inserted char 'b', cursor: (17, 3) -> (17, 4)
	    +++ Inserted string 'b', cursor: (17, 3) -> (17, 4)
	    +++ Inserting string ')'
	    +++   Inserted char ')', cursor: (17, 4) -> (17, 5)
	    +++ Inserted string ')', cursor: (17, 4) -> (17, 5)
	    +++ Inserting string ' '
	    +++   Inserted char ' ', cursor: (17, 5) -> (17, 6)
	    +++ Inserted string ' ', cursor: (17, 5) -> (17, 6)

	And that causes `wait_for` to think the "step" command is complete.
	This is wrong, as the prompt at line 17 isn't the prompt drawn after the
	completion of the "step" command.  The subsequent tests now run with a
	partially updated screen (what is shown above) and obviously fail.

	The ideal way to fix this would be for `wait_for` to be smarter, to
	avoid it confusing the different prompts drawn.

	However, I would also like to reduce the variations in TUI test results
	due to the directories (source and build) in which tests are ran.  TUI
	tests are more prone to differences in test results due to variations in
	directory names than other tests, as it makes curses take different
	redrawing decisions.  So in this patch, I propose to make TUI tests use
	"set filename-display basename", which makes GDB omit directory names
	when it prints file names.  This way, regardless of where you run the
	tests, you should get the same results (all other things being equal).

	Doing this happens to fix my failures and makes my CI happy (which in
	turns makes me happy).  To be clear, I understand that this does not fix
	the root issue of `proc wait_for` being confused.  However, it makes TUI
	test runs be more similar for everyone, such that there's less chance of
	TUI tests randomly failing for somebody.  If some other change triggers
	the `wait_for` problem again in the future, hopefully everybody will see
	the problem and we can work on getting it fixed more easily than if just
	one unlucky person sees the problem.

	Note that there are other reasons why TUI tests could vary, like
	different curses library versions taking different re-drawing decisions.
	However, I think my change is a good step towards more stable test
	results.

	pdb: _bfd_generic_close_and_cleanup
	Every format that might appear inside a generic archive needs to call
	_bfd_generic_close_and_cleanup, so that the archive element lookup
	htab can be tidied on closing an element.  Otherwise you get stale
	entries in the htab pointing at freed and perhaps reused memory,
	resulting in segfaults when the archive is closed.

	Calling _bfd_generic_close_and_cleanup on close means tdata needs to
	be set up too, since pdb claims to be of format bfd_archive.

	gdb/testsuite/lib/future.exp: follow dejagnu default_target_compile
	GDB's testsuite can override dejagnu's default_target_compile if the
	system provided dejagnu installation does not provide support to compile
	languages GDB needs.

	Recent version of dejagnu (1.6.3, installed on RHEL-9) includes ba60272
	"Establish a default C compiler by evaluating [find_gcc] if no other
	compiler is given."[1].  This commit removed calls such as
	`set_board_info compiler  "[find_gcc]"` from the various baseboards
	and has default_target_compile call `find_gcc` itself to find a compiler
	if none was specified by the board description.

	On systems with dejagnu-1.6.3, if GDB's overrides is needed to support
	languages still unknown to dejagnu, we end up in the following
	situation:
	  - The system board files do not set the C compiler anymore,
	  - GDB's replacement for default_target_compile assumes that the
	    compiler should have been set up by the board file.

	In this situation, no one sets the C compiler for the board and as a
	result many test are not compiled and not executed:

	    [...]
	    Running .../gdb/testsuite/gdb.base/bt-on-error-and-warning.exp ...
	    gdb compile failed, default_target_compile: No compiler to compile with
	    Running .../gdb/testsuite/gdb.base/dprintf-non-stop.exp ...
	    gdb compile failed, default_target_compile: No compiler to compile with
	    Running .../gdb/testsuite/gdb.base/structs3.exp ...
	    gdb compile failed, default_target_compile: No compiler to compile with
	    [...]

	We are observing this error with ROCgdb[2], a downstream port of GDB
	supporting AMD GPUs.  This port needs to use GDB's override of
	default_target_compile to compile HIP programs since dejagnu does not
	provide support for this language yet.

	This patch changes gdb_default_target_compile_1 in a similar way
	default_target_compile has been updated so both implementations remain
	compatible.  Even if this is not strictly required by GDB just yet,
	I believe keeping both implementations in sync desirable.

	Using board files provided with dejagnu <=1.6.2 is still supported: if
	the compiler is set by the board file, gdb_default_target_compile_1 uses
	it and does not need `find_gcc`.

	Patch tested on x86_64 RHEL-9 and ubuntu-20.04 on top of GDB and ROCgdb.

	gdb/python: restrict the names accepted by gdb.register_window_type
	I noticed that, from Python, I could register a new TUI window that
	had whitespace in its name, like this:

	  gdb.register_window_type('my window', MyWindowType)

	however, it is not possible to then use this window in a new TUI
	layout, e.g.:

	  (gdb) tui new-layout foo my window 1 cmd 1
	  Unknown window "my"
	  (gdb) tui new-layout foo "my window" 1 cmd 1
	  Unknown window ""my"
	  (gdb) tui new-layout foo my\ window 1 cmd 1
	  Unknown window "my\"

	GDB clearly uses the whitespace to split the incoming command line.

	I could fix this by trying to add a mechanism by which we can use
	whitespace within a window name, but it seems like an easier solution
	if we just forbid whitespace within a window name.  Not only is this
	easier, but I think this is probably the better solution, identifier
	names with spaces in would mean we'd need to audit all the places a
	window name could be printed and ensure that the use of a space didn't
	make the output ambiguous.

	So, having decided to disallow whitespace, I then thought about other
	special characters.  We currently accept anything as a window name,
	and I wondered if this was a good idea.

	My concerns were about how special characters used in a window name
	might cause confusion, for example, we allow '$' in window names,
	which is maybe fine now, but what if one day we wanted to allow
	variable expansion when creating new layouts?  Or what about starting
	a window name with '-'?  We already support a '-horizontal' option,
	what if we want to add more in the future?  Or use of the special
	character '{' which has special meaning within a new layout?

	In the end I figured it might make sense to place some restrictive
	rules in place, and then relax the rules later if/when users complain,
	we can consider each relaxation as its requested.

	So, I propose that window names should match this regular expression:

	  [a-zA-Z][-_.a-zA-Z0-9]*

	There is a chance that there is user code in the wild which will break
	with the addition of this change, but hopefully adapting to the new
	restrictions shouldn't be too difficult.

	gdb/testsuite: Add test to step through function epilogue
	The testsuite implicitly tests GDB's ability to step through epilogues
	in multiple tests, without doing it explicitly anywhere.  This is
	unfortunate, as clang does not emit epilogue information, so using clang
	on our testsuite makes many tests fail.  This patch adds a central,
	explicit test for walking through the epilogue so we can safely remove
	this from other tests and have them working with clang.

	The test created attempts to step through a simple epilogue, an
	epilogue that ends on another epilogue, and epilogues leading to other
	function calls.

	gdb.base/skip.exp: Use finish to exit functions
	gdb.base/skip.exp was making use of a fixed number of step commands to
	exit some functions.  This caused some problems when using clang to test
	GDB, as GDB would need fewer steps to reach the desired spots.  For
	instance, when testing in the section "step after disabling 3", the log
	looks like this:

	    Breakpoint 4, main () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:32
	    32        x = baz ((bar (), foo ()));
	    (gdb) step
	    bar () at binutils-gdb/gdb/testsuite/gdb.base/skip1.c:21
	    21        return 1;
	    (gdb) PASS: gdb.base/skip.exp: step after disabling 3: step 1
	    step
	    foo () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:42
	    42        return 0;
	    (gdb) PASS: gdb.base/skip.exp: step after disabling 3: step 2
	    step
	    main () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:34
	    34        test_skip_file_and_function ();
	    (gdb) step
	    test_skip_file_and_function () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:59
	    59        test_skip ();
	    (gdb) FAIL: gdb.base/skip.exp: step after disabling 3: step 3
	    step
	    test_skip () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:48
	    48      }
	    (gdb) PASS: gdb.base/skip.exp: step after disabling 3: step 4
	    step
	    test_skip_file_and_function () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:60
	    60        skip1_test_skip_file_and_function ();
	    (gdb) FAIL: gdb.base/skip.exp: step after disabling 3: step 5

	This shows that the feature is working but because the inferior lands in
	a different location, it registers as a failure.  Seeing as along with
	this difference, there are also some differences that depend on gcc
	versions (where gdb might stop back at line 32 before entering foo), it
	would not be easy to test for this behavior using steps and analzing
	where the inferior stops at each point. On the other hand, using
	gdb_step_until is not feasible because we'd possibly gloss over stepping
	into baz and rendering the whole test useless.  Instead, skip.exp now
	uses finish to leave functions, synchronizing through compilers and
	compiler versions.  Some test names were also changed to be a bit more
	descriptive.  The new log looks like this, independently of compiler used:

	    Breakpoint 4, main () at binutils-gdb/gdb/testsuite/gdb.base/skip.c:32
	    32        x = baz ((bar (), foo ()));

	little to allow the relative path.

	gdb/testsuite: fix gdb.base/msym-bp-shl when running with Clang
	When trying to test gdb.base/msym-bp-shl.exp using clang, it would have
	many failures because one of the version of the foo function was being

	gdb/testsuite: fix testing gdb.base/skip-inline.exp with clang
	When testing gdb.base/skip-inline.exp using clang, we get failures
	when trying to step out of functions, since clang requires one fewer
	step when compared to gcc.  The inferior gets increasingly out of sync
	as the test continues because of this difference, which generates those
	failures.

	This commit fixes this by switching those hardcoded steps to
	gdb_step_until, to guarantee that the inferior is always synced to what
	the test expects.  This approach does not work for the parts that use
	step 2 or step 3, so when we identify that clang is being used, those
	tests are skipped.

	Change gdb.base/skip-solib.exp deal with lack of epilogue information
	When running gdb.base/skip-solib.exp, the backtrace tests could fail with
	compilers that associated epilogue instructions with the last statement
	line of the function, instead of associating it with the closing brace,
	despite the feature being fully functional.  As an example, when testing
	skipping the function square, the testsuite would show

	Breakpoint 1, main () at (...)/binutils-gdb/gdb/testsuite/gdb.base/skip-solib-main.c:5
	5         return square(0);
	(gdb) step
	0x00007ffff7cef560 in __libc_start_call_main () from /lib64/libc.so.6
	(gdb) PASS: gdb.base/skip-solib.exp: ignoring solib file: step
	bt
	 #0  0x00007ffff7cef560 in __libc_start_call_main () from /lib64/libc.so.6
	 #1  0x00007ffff7cef60c in __libc_start_main_impl () from /lib64/libc.so.6
	 #2  0x0000000000401065 in _start ()
	(gdb) FAIL: gdb.base/skip-solib.exp: ignoring solib file: bt

	Which means that the feature is working, the testsuite is just
	mis-identifying it.  To avoid this problem, the skipped function calls
	have been sent to a line before `return`, so epilogues won't factor in.

	gdb/testsuite: Add a proc to test where compiler links the epilogue
	Different compilers link the epilogue of functions to different lines.
	As an example, gcc links it to the closing brace of the function,
	whereas clang links it to the last statement of the function.  This
	difference is important for the testsuite, since the where GDB will land
	after a step can be wildly different.  Where possible, this dependency
	should be side-stepped in the testsuite, but it isn't always possible,
	so this commit adds a gdb_caching_proc that is able to detect where the
	epilogue is linked, so tests can react accordingly.

	ld/testsuite: allow to force another directory for gcc linker
	Add a new variable "ld_testsuite_tmpdir" to enable manual configuration
	of the -B flag added to gcc calls. This flag ensure that gcc is invoking
	the linker and the assembler we want to test.

	When launching the testsuite outside of the build tree, the links made
	by the testsuite in tmpdir/ld will point to nothing. Thus, even with the
	PATH correctly setup towards the linker directory, gcc might end up
	falling back to its default linker. Hence this variable to ensure that
	gcc, whatever happens, is using the linker we want.

	RISC-V: Remove "b" operand type from disassembler
	There are a few operand types not used by any RISC-V instructions.

	-   Cx
	-   Vf
	-   Ve
	-   [
	-   ]
	-   b

	But most of them has a reasoning to keep them:

	-   Cx     : Same as "Ct" except it has a constraint to have rd == rs2
		     (similar to "Cw").  Although it hasn't used, its role is clear
		     enough to implement a new instruction with this operand type.
	-   Vf, Ve : Used by vector AMO instructions (not ratified and real
		     instructions are not upstreamed yet).
	-   [, ]   : Unused tokenization symbols.  Reserving them is not harmful
		     and a vendor may use this symbol for special purposes.

	... except "b".  I could not have found any reference to this operand type
	except it works like the "s" operand type.  Historically, it seems... it's
	just unused from the beginning.  Its role is not clear either.

	On such cases, we should vacate this room for the new operand type with
	much clearer roles.

	Following this convention, this commit adds three remaining macro-only

	gdbsupport: convert FILEIO_* macros to an enum
	Converting from free-form macros to an enum gives a bit of type-safety.
	This caught places where we would assign host error numbers to what
	should contain a target fileio error number, for instance in
	target_fileio_pread.

	I added the FILEIO_SUCCESS enumerator, because
	remote.c:remote_hostio_parse_result initializes the remote_errno output
	variable to 0.  It seems better to have an explicit enumerator than to
	assign a value for which there is no enumerator.  I considered
	initializing this variable to FILEIO_EUNKNOWN instead, such that if the
	remote side replies with an error and omits the errno value, we'll get
	an errno that represents an error instead of 0 (which reprensents no
	error).  But it's not clear what the consequences of that change would
	be, so I prefer to err on the side of caution and just keep the existing
	behavior (there is no intended change in behavior with this patch).

	Note that remote_hostio_parse_resul still reads blindly what the remote
	side sends as a target errno into this variable, so we can still end up
	with a nonsensical value here.  It's not good, but out of the scope of
	this patch.

	Convert host_to_fileio_error and fileio_errno_to_host to return / accept
	a fileio_error instead of an int, and cascade the change in the whole
	chain that uses that.

	The problem is this line in path_join:

	    gdb_assert (strlen (path) == 0 || !IS_ABSOLUTE_PATH (path));

	... where `path` is "x".  IS_ABSOLUTE_PATH eventually calls
	HAS_DRIVE_SPEC_1:

	    #define HAS_DRIVE_SPEC_1(dos_based, f)                  \
	      ((f)[0] && ((f)[1] == ':') && (dos_based))

	This macro accesses indices 0 and 1 of the input string.  However, `f`
	is a string_view of length 1, so it's incorrect to try to access index
	1.  We know that the string_view's underlying object is a null-terminated
	string, so in practice there's no harm.  But as far as the string_view
	is concerned, index 1 is considered out of bounds.

	This patch makes the easy fix, that is to change the path_join parameter
	from a vector of to a vector of `const char *`.  Another solution would
	be to introduce a non-standard gdb::cstring_view class, which would be a
	view over a null-terminated string.  With that class, it would be
	correct to access index 1, it would yield the NUL character.  If there
	is interest in having this class (it has been mentioned a few times in
	the past) I can do it and use it here.

	This was found by running tests such as gdb.ada/arrayidx.exp, which
	produce 1-char long filenames, so adding a new test is not necessary.

	PR29573, addr2line doesn't display file/line for local symbols
	The DWARF standard is clear that DW_AT_linkage_name is optional.
	Compilers may not provide the attribute on functions and variables,
	even though the language mangles names.  g++ does not for local
	variables and functions.  Without DW_AT_linkage_name, mangled object
	file symbols can't be directly matched against the source-level
	DW_AT_name in DWARF info.  One possibility is demangling the object
	file symbols, but that comes with its own set of problems:
	1) A demangler might not be available for the compiler/language.
	2) Demangling doesn't give the source function name as stored in
	   DW_AT_name.  Class and template parameters must be stripped at
	   least.

	So this patch takes a simpler approach.  A symbol matches DWARF info
	if the DWARF address matches the symbol address, and if the symbol
	name contains the DWARF name as a sub-string.  Very likely the name
	matching is entirely superfluous.

	RISC-V: Always generate R_RISCV_CALL_PLT reloc for call in assembler.
	Since we have the same behaviors of CALL and CALL_PLT relocs in linker for now,
	https://github.com/bminor/binutils-gdb/commit/3b1450b38c644f99aa2e211747b428b9f8d15cca

	And the psabi already deprecate the CALL reloc,
	https://github.com/riscv-non-isa/riscv-elf-psabi-doc/commit/a0dced85018d7a0ec17023c9389cbd70b1dbc1b0

	Therefore, we should always generate R_RISCV_CALL_PLT reloc for call, even if
	it has @plt postfix.  I believe LLVM (https://reviews.llvm.org/D132530) already
	support this, so GNU as should do the same thing.

	gdb/testsuite: add a debuginfod-support.exp helper library
	We currently have a single test for GDB's debuginfod support, this is
	gdb.debuginfod/fetch_src_and_symbols.exp, this script does all the
	setup, starts debuginfod, and then does the testing.

	This commit tries to split the existing script in two, there is a new
	library lib/debuginfod-support.exp, which contains a helper functions
	related to running debuginfod tests.  All the code in the new library
	is basically copied from the existing test case (which is why I
	retained the copyright date range on the new library), with some minor
	adjustments to try and make the code a little more generic.

	One change I made, for example, is the library offers functions to
	shut down debuginfod, previously we just relied on expect shutting
	down debuginfod when dejagnu completed.

	The existing test script is updated to make use of the new library
	code, and this test is still passing for me.  The only change in the
	test results is a single test where I changed the name to remove the
	port number from the test name - the port number can change from run
	to run, so could make it hard to compare test results.

	I have also done a little light house keeping on the original test
	script, updating and adding new comments, and making use of
	proc_with_prefix in a couple of places.

	LoongArch: Fix R_LARCH_IRELATIVE insertion after elf_link_sort_relocs
	loongarch_elf_finish_dynamic_symbol is called after elf_link_sort_relocs
	if -z combreloc.  elf_link_sort_relocs redistributes the contents of
	.rela.* sections those would be merged into .rela.dyn, so the slot for
	R_LARCH_IRELATIVE may be out of relplt->contents now.

	To make things worse, the boundary check

	    dyn < dyn + relplt->size / sizeof (*dyn)

	is obviously wrong ("x + 10 < x"? :), causing the issue undetected
	during the linking process and the resulted executable suddenly crashes
	at runtime.

	The issue was found during an attempt to add static-pie support to the
	toolchain.

	Fix it by iterating through the inputs of .rela.dyn to find the slot.

	LoongArch: Don't write into GOT for local ifunc
	Local ifuncs are always resolved at runtime via R_LARCH_IRELATIVE, so
	there is no need to write anything into GOT.  And when we write the GOT
	we actually trigger a heap-buffer-overflow: If a and b are different
	sections, we cannot access something in b with "a->contents + (offset
	from a)" because "a->contents" and "b->contents" are heap buffers
	allocated separately, not slices of a large buffer.

	So stop writing into GOT for local ifunc now.

	During symbol reading: file index out of range^M
	$1 = 0^M
	(gdb) FAIL: gdb.dwarf2/dw2-no-code-cu.exp: p var with no complaints

	This is a regression since commit 6d263fe46e0 ("Avoid bad breakpoints with

	+  if (lowpc != highpc)
	+    handle_DW_AT_stmt_list (die, cu, fnd, lowpc);

	The change intends to avoid a problem with a check in
	lnp_state_machine::check_line_address, but also prevents the file and dir

	BFD error message suppression test case
	This commit adds a GDB test case which tests GDB's BFD error handler
	hook for suppressing output of all but the first identical messages.

	See the comment at the beginning of bfd-errors.exp for details about
	this new test.

	I've tested this test for both 32- and 64-bit ELF files and also
	on both little endian and big endian machines.  It also works for
	both native and remote targets.  The only major restriction is that
	it only works for ELF targets.

2022-09-17  Kevin Buettner  <kevinb@redhat.com>

	Suppress printing of superfluous BFD error messages
	This commit adds a hook to the BFD error handler for suppressing
	identical messages which have been output once already.

	It's motivated by this Fedora bug...

	https://bugzilla.redhat.com/show_bug.cgi?id=2083315

	...in which over 900,000 BFD error messages are output when attaching
	to firefox.  From the bug report, the messages all say:

	BFD: /usr/lib/debug/usr/lib64/firefox/libxul.so-100.0-2.fc35.x86_64.debug: attempt to load strings from a non-string section (number 38)

	Since there's no (additional) context which might assist the user in
	determining what's wrong, there's really no point in outputting more
	than one message.  Of course, if BFD should output some
	other/different message, it should be output too, but all future
	messages identical to those already output should be suppressed.

	For the firefox problem, it turned out that there were only 37
	sections, but something was referring to section #38.  I haven't
	investigated further to find out how this came to be.

	Despite this problem, useful debugging might still be done, especially
	if the user doesn't care about debugging the problematic library.

	If it turns out that knowing the quantity of messages might be useful,
	I've implemented the suppression mechanism by keeping a count of each
	identical message.  A new GDB command, perhaps a 'maintenance'
	command, could be added to print out each message along with the
	count.  I haven't implemented this though because I'm not convinced of
	its utility.  Also, the BFD message printer has support for BFD-
	specific format specifiers.  The BFD message strings that GDB stores
	in its map are sufficient for distinguishing messages from each
	other, but are not identical to those output by BFD's default error
	handler.  So, that problem would need to be solved too.

	[gdb] Handle pending ^C after rl_callback_read_char
	In completion tests in various test-cases, we've been running into these
	"clearing input line" timeouts:
	...
	(gdb) $cmd^GPASS: gdb.gdb/unittest.exp: tab complete "$cmd"
	FAIL: gdb.gdb/unittest.exp: tab complete "$cmd" (clearing input line) (timeout)
	...
	where $cmd == "maintenance selftest name_that_does_not_exist".

	AFAIU, the following scenario happens:
	- expect sends "$cmd\t"
	- gdb detects the stdin event, and calls rl_callback_read_char until it
	  comes to handle \t
	- readline interprets the \t as completion, tries to complete, fails to do so,
	  outputs a bell (^G)
	- expect sees the bell, and proceeds to send ^C
	- readline is still in the call to rl_callback_read_char, and stores the
	  signal in _rl_caught_signal
	- readline returns from the call to rl_callback_read_char, without having
	  handled _rl_caught_signal
	- gdb goes to wait for the next event
	- expect times out waiting for "Quit", the expected reaction for ^C

	Fix this by handling pending signals after each call to rl_callback_read_char.

	The fix is only available for readline 8.x, if --with-system-readline provides
	an older version, then the fix is disabled due to missing function
	rl_check_signals.

	Tested on x86_64-linux.

	bfd: Stop using -Wstack-usage=262144 when built with Clang
	Some components of GNU Binutils will pass "-Wstack-usage=262144" when
	"GCC >= 5.0" is detected.  However, Clang does not support "-Wstack-usage",
	despite that related configuration part in bfd/warning.m4 handles the latest
	Clang (15.0.0 as of this writing) as "GCC >= 5.0".

	The option "-Wstack-usage" was ignored when the first version of Clang is
	released but even this "ignoring" behavior is removed before Clang 4.0.0.
	So, if we give Clang "-Wstack-usage=262144", it generates a warning, making
	the build failure.

	This commit checks "__clang__" macro to prevent adding the option if the
	compiler is identified as Clang.

	gdb/testsuite: Update gdb.base/so-impl-ld.exp
	gdb.base/so-impl-ld.exp was setup assuming that the compiler would add
	epilogue information and that GDB would stop in the } line.  This would
	make clang tests fail like so:

	 step^M
	 solib_main (arg=10000) at ../../../common/git-repos/binutils-gdb/gdb/testsuite/gdb.base/solib1.c:7^M
	 7|__  return arg*arg;|__|___/* HERE */^M
	 (gdb) PASS: gdb.base/so-impl-ld.exp: step into solib call
	 next^M
	 main () at ../../../common/git-repos/binutils-gdb/gdb/testsuite/gdb.base/so-impl-ld.c:22^M

	 (gdb) FAIL: gdb.base/so-impl-ld.exp: step out of solib call

	This patch changes it so solib_main has 2 lines where GDB can stop
	regardless of compiler choices, and updates the exp file to
	generically deal with unknown number of steps until leaving that
	function.

	gdb/testsuite: introduce gdb_step_until
	Currently, GDB's testsuite uses a set amount of step commands to exit
	functions. This is a problem if a compiler emits different epilogue
	information from gcc, or emits no epilogue information at all. It was
	most noticeable if Clang was used to test GDB.

	To fix this unreliability, this commit introduces a new proc that will
	step the inferior until it is stopped at a line that matches the given
	regexp, or until it steps too many times - defined as an optional
	argument. If the line is found, it shows up as a single PASS in the
	test, and if the line is not found, a single FAIL is emitted.

	This patch only introduces this proc, but does not add it to any
	existing tests, these will be introduced in the following commit.

2022-09-13  Bruno Larsen  <blarsen@redhat.com>

	explicitly test for stderr in gdb.base/dprintf.exp
	Not all compilers add stderr debug information when compiling a
	program. Clang, for instance, prefers to add nothing from standard
	libraries and let an external debug package have this information.
	Because of this, gdb.base/dprintf.exp was failing when GDB attempted to
	use dprintf as a call to fprintf(stderrr, ...), like this:

	 (gdb) PASS: gdb.base/dprintf.exp: call: fprintf: set dprintf style to call
	 continue
	 Continuing.
	 kickoff 1234
	 also to stderr 1234
	 'stderr' has unknown type; cast it to its declared type
	 (gdb) FAIL: gdb.base/dprintf.exp: call: fprintf: 1st dprintf (timeout)

	To avoid this false positive, we explicitly test to see if
	the compiler has added information about stderr at all, and abort
	testing dprintf as an fprintf call if it is unavailable.

	Fix gdb.base/call-ar-st to work with Clang
	When running gdb.base/call-ar-st.exp against Clang, we see one FAIL,
	like so:

	 print_all_arrays (array_i=<main.integer_array>, array_c=<main.char_array> "ZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZa
	 ZaZaZaZaZaZaZaZaZaZaZaZa", array_f=<main.float_array>, array_d=<main.double_array>) at ../../../src/gdb/testsuite/gdb.base/call-ar-st.c:274
	 274       print_int_array(array_i);     /* -step1- */
	 (gdb) FAIL: gdb.base/call-ar-st.exp: step inside print_all_arrays

	With GCC we instead see:

	 print_all_arrays (array_i=<integer_array>, array_c=<char_array> "ZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZaZa", array_f=<float_array>, array_d=<double_array>) at /home/pedro/gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.base/call-ar-st.c:274
	 274       print_int_array(array_i);     /* -step1- */
	 (gdb) PASS: gdb.base/call-ar-st.exp: step inside print_all_arrays

	The difference is that with Clang we get:

	 array_i=<main.integer_array>, ...

	instead of

	 array_i = <integer_array>, ...

	These symbols are local static variables, and "main" is the name of
	the function they are defined in.  GCC instead appends a sequence
	number to the linkage name:

	 $ nm -A call-ar-st.gcc | grep integer_
	 call-ar-st/call-ar-st:00000000000061a0 b integer_array.3968

	 $ nm -A call-ar-st.clang | grep integer_
	 call-ar-st:00000000004061a0 b main.integer_array

	This commit changes the testcase to accept both outputs, as they are
	functionally identical.

	Clang was optimizing global_var away because it was not being used
	anywhere. this commit fixes that by adding the attribute used it.

	update gdb.base/info-program.exp to not fail with clang
	The test specifically mentions that it doesn't care where the program
	stops, however it was still testing for a specific location.  The clang
	compiler emits different line information for epilogue, so GDB reports a
	different stopping location, depending on the used compiler.  With this
	patch the test works even with clang.

	gdb/testsuite: change gdb.base/nodebug.exp to not fail with clang
	Clang organizes the variables differently to gcc in the original version

	gcc:
	$16 = (int *) 0x404034 <datalocal>

	clang:
	$16 = (int *) 0x404034 <dataglobal8>

	However, since the important part of this test doesn't seem to be which
	symbol is linked, but rather if GDB is correctly increasing the
	address. This test was changed to actually measure address changes,
	instead of assuming the ordering and naming of symbols.

	ld: pe: Apply review suggestions on the existing exports/imports arrays
	Use a separate explicit max_exports/imports field, instead of
	deducing it from the number of allocated elements. Use a named
	constant for the incremental growth of the array.

	Use bool instead of int for boolean values.

	Remove an unnecessary if statement/scope in the def_file_free
	function.

	Add more verbose comments about parameters, and about insertion
	into an array of structs.

	Generally use unsigned integers for all array indices and sizes.
	The num_exports/imports fields are kept as is as signed integers,
	since changing them to unsigned would require a disproportionate
	amount of changes ti pe-dll.c to avoid comparisons between signed
	and unsigned.

	Simply use xrealloc instead of a check and xmalloc/xrealloc;
	xrealloc can take NULL as the first parameter (and does a similar
	check internally). (This wasn't requested in review though,
	but noticed while working on the code.)

	ld: pe: Improve performance of object file exclude symbol directives
	Store the list of excluded symbols in a sorted list, speeding up
	checking for duplicates when inserting new entries.

	This is done in the same way as is done for exports and imports
	(while the previous implementation was done with a linked list,
	based on the implementation for aligncomm).

	When linking object files with excluded symbols, there can potentially
	be very large numbers of excluded symbols (just like builds with
	exports can have a large number of exported symbols).

	This improves the link performance somewhat, when linking with large
	numbers of excluded symbols.

	The later actual use of the excluded symbols within pe-dll.c
	handles them via an unordered linked list still, though.

	...
	Running selftest run_on_main_thread.

	  done = false;

	  {

	     something.  */
	  SELF_CHECK (done);

	  thread.join ();
	}
	...

	The error message we see is due to the destructor of thread being called while
	thread is joinable.

	This is supposed to be taken care of by thread.join (), but the ^C prevents
	that one from being called, while the destructor is still called.

	Fix this by ensuring thread.join () is called (if indeed required) before the
	destructor using SCOPE_EXIT.

	In commit cd919f5533c ("[gdb/testsuite] Fix
	gdb.dwarf2/dw2-dir-file-name.exp"), I made gdb.dwarf2/dw2-dir-file-name.exp
	independent of prologue analyzers, using this change:
	...
	-       gdb_breakpoint $func
	+       gdb_breakpoint *$func
	...

	That however caused a regression on ppc64le.  For PowerPC, as described in the
	ELFv2 ABI, a function can have a global and local entry point.

	Setting a breakpoint on *$func effectively creates a breakpoint for the global
	entry point, so if the function is entered through the local entry point, the
	breakpoint doesn't trigger.

	Fix this by reverting commit cd919f5533c, and setting the breakpoint on
	${func}_label instead.

	Tested on x86_64-linux and ppc64le-linux.

	x86: avoid i386_dis_printf()'s staging area for a fair part of output
	While PR binutils/29483 has now been addressed differently, this
	originally proposed change still has its merits: Avoiding vsnprintf()
	for typically far more than half of the overall output results in a 2-3%
	performance gain in my testing (with debug builds of objdump, libbfd,
	and libopcodes).

	With that part of output no longer using staging_area[], the array also
	doesn't need to be quite as large anymore (the largest presently used
	size is 27, from "64-bit address is disabled").

	While limiting the scope of "res" it became apparent that
	- no caller cares about the function's return value,
	- the comment about the return value was wrong,
	- a particular positive return value would have been meaningless to the
	  caller.
	Therefore convert the function to return "void" at the same time.

	RISC-V: PR28509, the default visibility symbol cannot be referenced by R_RISCV_JAL.

	may relax the R_RISCV_CALL relocations to R_RISCV_JAL or R_RISCV_RVC_JUMP,

	(gdb) p (int) foo ()^M
	Invalid cast.^M
	(gdb) FAIL: gdb.dwarf2/dw2-unspecified-type.exp: p (int) foo ()
	...
	because DW_TAG_unspecified_type is translated as void.

	There's some code in read_unspecified_type that marks the type as stub, but
	that's only active for ada:
	...
	  if (cu->lang () == language_ada)
	    type->set_is_stub (true);

	Fix this by:

	RISC-V: Fix vector CSR requirements
	Vector CSRs are also required on smaller vector subsets.

	Not only that the most of vector CSRs are general purpose (and must be
	accessible for every vector subsets), current minimum vector subset 'Zve32x'
	requires fixed point arithmetic, making remaining non-general purpose
	(fixed point arithmetic only) CSRs mandatory for such subsets.

	gdbsupport: Fix config.status dependency
	Commit 171fba11ab27 ("Make GDBserver abort on internal error in development mode")
	created a new substitution CONFIG_STATUS_DEPENDENCIES but this is used by
	Makefile.in (which is not regenerated by that commit).  After regenerating
	it, it is found that CONFIG_STATUS_DEPENDENCIES value is not valid, making
	gdbsupport fail to build.

	Since the CONFIG_STATUS_DEPENDENCIES value is used in the Makefile, macro
	substitution must have a Makefile format but commit 171fba11ab27 used shell
	format "$srcdir/../bfd/development.sh".

	This commit fixes this issue by substituting "$srcdir" (shell format) to
	"$(srcdir)" (Makefile format).  It preserves the dependency as Pedro
	intended and fixes the build problem.

	The difference comes from the gdbarch_skip_prologue implementation.

	The amd64_skip_prologue implementation doesn't use gcc line numbers, and falls
	back to the architecture-specific prologue analyzer, which correctly skips

	The second entry is interpreted as end-of-prologue, so 0x402580 is used, while

	  40259c:       d503201f        nop

	Note that the architecture-specific prologue analyzer would have gotten this
	right:
	...
	(gdb) p /x aarch64_analyze_prologue (gdbarch, pc, pc + 128, 0)
	$2 = 0x40258c

	Fix endianness handling for arm record self tests
	v2:

	- Add 32-bit Arm instruction selftest
	- Refactored abstract memory reader into abstract instruction reader
	- Adjusted code to use templated type and to use host endianness as
	  opposed to target endianness.

	The arm record tests handle 16-bit and 32-bit thumb instructions, but the
	code is laid out in a way that handles the 32-bit thumb instructions as
	two 16-bit parts.

	This is fine, but it is prone to host-endianness issues given how the two
	16-bit parts are stored and how they are accessed later on. Arm is
	little-endian by default, so running this test with a GDB built with
	--enable-targets=all and on a big endian host will run into the following:

	Running selftest arm-record.
	Process record and replay target doesn't support syscall number -2036195
	Process record does not support instruction 0x7f70ee1d at address 0x0.
	Self test failed: self-test failed at ../../binutils-gdb/gdb/arm-tdep.c:14482

	It turns out the abstract memory reader class is more generic than it needs to
	be, and we can simplify the code a bit by assuming we have a simple instruction
	reader that only reads up to 4 bytes, which is the length of a 32-bit
	instruction.

	Instead of returning a bool, we return instead the instruction that has been
	read. This way we avoid having to deal with the endianness conversion, and use
	the host endianness instead. The Arm selftests can be executed on non-Arm
	hosts.

	While at it, Tom suggested adding a 32-bit Arm instruction selftest to increase
	the coverage of the selftests.

	[gdb/testsuite] Use prototype to call libc functions
	On openSUSE Tumbleweed (using glibc 2.36), I run into:
	...

	(gdb) FAIL: gdb.base/break-main-file-remove-fail.exp: cmdline: \
	  get integer valueof "(int) munmap (4198400, 4096)"
	...

	The problem is that after starting the executable, the symbol has type
	"void (*) (void)":
	...
	(gdb) p munmap
	$1 = {<text variable, no debug info>} 0x401030 <munmap@plt>
	(gdb) start
	  ...
	(gdb) p munmap
	$2 = {void (void)} 0x7ffff7feb9a0 <__GI_munmap>
	...
	which causes the "Invalid cast" error.

	Looking at the debug info for glibc for symbol __GI_munmap:
	...

	    <189691>   DW_AT_name        : ../sysdeps/unix/syscall-template.S

	    <1896bc>   DW_AT_high_pc     : 37
	...
	that's probably caused by this bit (or similar bits for other munmap aliases).

	This is fixed in gas on trunk by commit 5578fbf672e ("GAS: Add a return type
	tag to DWARF DIEs generated for function symbols").

	Work around this (for say gas 2.39) by explicitly specifying the prototype for

	gdb: Add non-enum disassembler options
	This is paired with "opcodes: Add non-enum disassembler options".

	There is a portable mechanism for disassembler options and used on some
	architectures:

	-   ARC
	-   Arm
	-   MIPS
	-   PowerPC
	-   RISC-V
	-   S/390

	However, it only supports following forms:

	-   [NAME]
	-   [NAME]=[ENUM_VALUE]

	Valid values for [ENUM_VALUE] must be predefined in
	disasm_option_arg_t.values. For instance, for -M cpu=[CPU] in ARC
	architecture, opcodes/arc-dis.c builds valid CPU model list from
	include/elf/arc-cpu.def.

	In this commit, it adds following format:

	-   [NAME]=[ARBITRARY_VALUE] (cannot contain "," though)

	This is identified by NULL value of disasm_option_arg_t.values
	(normally, this is a non-NULL pointer to a NULL-terminated list).

	[gdb/symtab] Support .debug_names section with TUs in .debug_info
	When running test-case gdb.cp/cpexprs-debug-types.exp on target board
	cc-with-debug-names/gdb:debug_flags=-gdwarf-5, we get an executable with
	a .debug_names section, but no .debug_types section.  For dwarf-5, the TUs
	are no longer put in a separate unit, but instead they're put in the
	.debug_info section.

	When loading the executable, the .debug_names section is silently ignored
	because of this check in dwarf2_read_debug_names:
	...
	  if (map->tu_count != 0)
	    {
	      /* We can only handle a single .debug_types when we have an
	         index.  */
	      if (per_bfd->types.size () != 1)
	        return false;
	...
	which triggers because per_bfd->types.size () == 0.

	The intention of the check is to make sure we don't have more that one
	.debug_types section, as can happen in a object file (see PR12984):
	...
	$ grep "\.debug_types" 11.s
	        .section        .debug_types,"G",@progbits,wt.75c042c23a9a07ee,comdat

	Fix this by:
	- changing the check condition to "per_bfd->types.size () > 1", and
	- handling per_bfd->types.size () == 0.

	sim/erc32: fix gdb with simulator build
	In commit:

	      sim: fixes for libopcodes styled disassembler

	changes were made to the simulator source to handle the new libopcodes
	disassembler styling API.

	Unfortunately, these changes broke building GDB with the erc32 (sparc)
	simulator, like this:

	  ../src/configure --target=sparc-linux
	  make all-gdb
	  ....
	  /usr/bin/ld: ../sim/erc32/libsim.a(interf.o): in function `sim_open':
	  /tmp/build/sim/../../src/sim/erc32/interf.c:247: undefined reference to `fprintf_styled'
	  collect2: error: ld returned 1 exit status

	The problem is that in commit 7b01c1cc1d11 the fprintf_styled function
	was added into sis.c.  This file is only used when building the 'run'
	binary, that is, the standalone simulator, and is not included in the
	libsim.a library.

	Now, the obvious fix would be to move fprintf_styled into libsim.a,
	however, that turns out to be tricky.

	The erc32 simulator currently has two copies of the function run_sim,
	one in sis.c, and one in interf.c, both of these copies are global.

	Currently, the 'run' binary links fine, though I suspect this might be
	pure luck.  When I tried moving fprintf_styled into interf.c, I ran
	into multiple-definition (of run_sim) errors.  I suspect that by
	requiring the linker to pull in fprintf_styled from libsim.a I was
	changing the order in which symbols were loaded, and the linker was
	now seeing both copies of run_sim, while currently we only see one
	copy.

	The ideal solution of course, would be to merge the two similar, but
	slightly different copies of run_sim, and just use the one copy.  Then
	we could safely move fprintf_styled into interf.c too, and all would
	be good.

	But I don't have time right now to start debugging the erc32
	simulator, so I wanted a solution that fixes the build without
	introducing multiple definition errors.

	The easiest solution I think is to just have two copies of
	fprintf_styled, one in sis.c, and one in interf.c.  Unlike run_sim,
	these two copies are both static, so we will not run into multiple
	definition issues with this function.  The functions themselves are
	not very big, so it's not a huge amount of duplicate code.

	I am very aware that this is not an ideal solution, and I would
	welcome anyone who wants to take on fixing the run_sim problem
	properly, and then cleanup the fprintf_styled duplication.

	Remove a call to clear_interpreter_hooks
	mi_interp::resume does not need to call clear_interpreter_hooks,
	because this is already done by interp_set.

	TUI stdout buffering cleanup
	The TUI checks against gdb_stdout to decide when to buffer.  It seems
	much cleaner to me to simply record this as an attribute of the stream
	itself.

	Remove a ui-related memory leak
	gdb_setup_readline makes new streams and assigns to the various stream
	members of struct ui.  However, these assignments cause the previous
	values to leak.  As far as I can, this code is simply unnecessary and
	can be removed -- with the exception of the assignment to gdb_stdtarg,
	which is not initialized anywhere else.

	Remove tui_out_new
	tui_out_new is just a simple wrapper for 'new' and can be removed,
	simplifying gdb a tiny bit.

	Use scoped_restore in safe_parse_type
	This changes safe_parse_type to use scoped_restore rather than
	explicit assignments.

	Use member initialization in 'struct ui'
	This changes 'struct ui' to use member initialization.  This is
	simpler to understand.

	Remove two unused members from mi_interp
	These members of mi_interp aren't used and can be removed.

	Remove obsolete filtering comment
	top.h has an obsolete comment about the use of _unfiltered.

	Remove the "for moment" comments
	A few spots setting some gdb output stream variables have a "for
	moment" comment.  These comments aren't useful and I think the moment
	has passed -- these are permanent now.

	Use ui_out_redirect_pop in more places
	This changes ui_out_redirect_pop to also perform the redirection, and
	then updates several sites to use this, rather than explicit
	redirects.

	Free ui::line_buffer
	A ui initializes its line_buffer, but never calls buffer_free on it.
	This patch fixes the oversight.  I found this by inspection.

	Remove some dead code
	This patch removes some dead code and an old FIXME.  These no longer
	seem useful, even for documentation purposes.

	Let ui::input_fd be -1
	This changes gdb so that, if ui::input_fd is set to -1, then it will
	not be registered with the event loop.  This is useful for the DAP
	support code I wrote, but as it turns out to also be useful to
	Insight, it seems best to check it in separately.

	gdb/riscv: better support for fflags and frm registers
	First, some background on the RISC-V registers fflags, frm, and fcsr.

	These three registers all relate to the floating-point status and
	control mechanism on RISC-V.  The fcsr is the floatint-point control
	status register, and consists of two parts, the flags (bits 0 to 4)
	and the rounding-mode (bits 5 to 7).

	The fcsr register is just one of many control/status registers (or
	CSRs) available on RISC-V.  The fflags and frm registers are also
	CSRs.  These CSRs are aliases for the relevant parts of the fcsr
	register.  So fflags is an alias for bits 0 to 4 of fcsr, and frm is
	an alias for bits 5 to 7 of fcsr.

	This means that a user can change the floating-point rounding mode
	either, by writing a complete new value into fcsr, or by writing just
	the rounding mode into frm.

	How this impacts on GDB is like this: a target description could,
	legitimately include all three registers, fcsr, fflags, and frm.  The
	QEMU target currently does this, and this makes sense.  The target is
	emulating the complete system, and has all three CSRs available, so
	why not tell GDB about this.

	In contrast, the RISC-V native Linux target only has access to the
	fcsr.  This is because the ptrace data structure that the kernel uses
	for reading and writing floating point state only contains a copy of
	the fcsr, after all, this one field really contains both the fflags
	and frm fields, so why carry around duplicate data.

	So, we might expect that the target description for the RISC-V native
	Linux GDB would only contain the fcsr register.  Unfortunately, this
	is not the case.  The RISC-V native Linux target uses GDB's builtin
	target descriptions by calling riscv_lookup_target_description, this
	will then add an fpu feature from gdb/features/riscv, either
	32bit-fpu.xml or 64bit-fpu.xml.  The problem, is that these features
	include an entry for fcsr, fflags, and frm.  This means that GDB
	expects the target to handle reading and writing these registers.  And
	the RISC-V native Linux target currently doesn't.

	In riscv_linux_nat_target::store_registers and
	riscv_linux_nat_target::fetch_registers only the fcsr register is
	handled, this means that, for RISC-V native Linux, the fflags and frm
	registers always show up as <unavailable> - they are present in the
	target description, but the target doesn't know how to access the
	registers.

	A final complication relating to these floating pointer CSRs is which
	target description feature the registers appear in.

	These registers are CSRs, so it would seem sensible that these
	registers should appear in the CSR target description feature.

	However, when I first added RISC-V target description support, I was
	using a RISC-V simulator that didn't support any CSRs other than the
	floating point related ones.  This simulator bundled all the float
	related CSRs into the fpu target feature.  This didn't feel completely
	unreasonable to me, and so I had GDB check for these registers in
	either target feature.

	In this commit I make some changes relating to how GDB handles the
	three floating point CSR:

	1. Remove fflags and frm from 32bit-fpu.xml and 64bit-fpu.xml.  This
	means that the default RISC-V target description (which RISC-V native
	FreeBSD), and the target descriptions created for RISC-V native Linux,
	will not include these registers.  There's nothing stopping some other
	target (e.g. QEMU) from continuing to include all three of these CSRs,
	the code in riscv-tdep.c continues to check for all three of these
	registers, and will handle them correctly if they are present.

	2. If a target supplied fcsr, but does not supply fflags and/or frm,
	then RISC-V GDB will now create two pseudo registers in order to
	emulate the two missing CSRs.  These new pseudo-registers do the
	obvious thing of just reading and writing the fcsr register.

	3. With the new pseudo-registers we can no longer make use of the GDB
	register numbers RISCV_CSR_FFLAGS_REGNUM and RISCV_CSR_FRM_REGNUM.
	These will be the numbers used if the target supplies the registers in
	its target description, but, if GDB falls back to using
	pseudo-registers, then new, unique numbers will be used.  To handle
	this I've added riscv_gdbarch_tdep::fflags_regnum and
	riscv_gdbarch_tdep::frm_regnum, I've then updated the RISC-V code to
	compare against these fields.

	When adding the pseudo-register support, it is important that the
	pseudo-register numbers are calculated after the call to
	tdesc_use_registers.  This is because we don't know the total number
	of physical registers until after this call, and the psuedo-register
	numbers must follow on from the real (target supplied) registers.

	I've updated some tests to include more testing of the fflags and frm
	registers, as well as adding a new test.

	gdb: Add tdesc_found_register function to tdesc API
	This commit adds a new function to the target description API within
	GDB.  This new function is not used in this commit, but will be used
	in the next commit, I'm splitting it out into a separate patch for
	easier review.

	What I want to do in the next commit is check to see if a target
	description supplied a particular register, however, the register in
	question could appear in one of two possible features.

	The new function allows me to ask the tdesc_arch_data whether a
	register was found and assigned a particular GDB register number once
	all of the features have been checked.  I think this is a much simpler
	solution than adding code such that, while checking each feature, I
	spot if the register I'm processing is the one I care about.

	No tests here as the new code is not used, but this code will be
	exercised in the next commit.

	gdb/riscv: improve (and fix) display of frm field in 'info registers'
	On RISC-V the FCSR (float control/status register) is split into two
	parts, FFLAGS (the flags) and FRM (the rounding mode).  Both of these
	two fields are part of the FCSR register, but can also be accessed as
	separate registers in their own right.  And so, we have three separate
	registers, $fflags, $frm, and $fcsr, with the last of these being the
	combination of the first two.

	Here's how the bits of FCSR are split between FRM and FFLAGS:

	         ,--------- FFLAGS
	       |---|
	    76543210 <----- FCSR
	    |-|
	     '--------------FRM

	Here's how GDB currently displays these registers:

	  (gdb) info registers $fflags $frm $fcsr
	  fflags         0x0      RD:0 NV:0 DZ:0 OF:0 UF:0 NX:0
	  frm            0x0      FRM:0 [RNE (round to nearest; ties to even)]
	  fcsr           0x0      RD:0 NV:0 DZ:0 OF:0 UF:0 NX:0 FRM:0 [RNE (round to nearest; ties to even)]

	Notice the 'RD' field which is present in both $fflags and $fcsr.
	This field contains the value of the FRM field, which makes sense when
	displaying the $fcsr, but makes no sense when displaying $fflags, as
	the $fflags doesn't include the FRM field.

	Additionally, the $fcsr already includes an FRM field, so the
	information in 'RD' is duplicated.  Consider this:

	  (gdb) set $frm = 0x3
	  (gdb) info registers $fflags $frm $fcsr                             │
	  fflags         0x0      RD:0 NV:0 DZ:0 OF:0 UF:0 NX:0
	  frm            0x3      FRM:3 [RUP (Round up towards +INF)]
	  fcsr           0x60     RD:3 NV:0 DZ:0 OF:0 UF:0 NX:0 FRM:3 [RUP (Round up towards +INF)]

	See how the 'RD' field in $fflags still displays 0, while the 'RD' and
	'FRM' fields in $fcsr show the same information.

	The first change I propose in this commit is to remove the 'RD'
	field.  After this change the output now looks like this:

	  (gdb) info registers $fflags $frm $fcsr
	  fflags         0x0      NV:0 DZ:0 OF:0 UF:0 NX:0
	  frm            0x0      FRM:0 [RNE (round to nearest; ties to even)]
	  fcsr           0x0      NV:0 DZ:0 OF:0 UF:0 NX:0 FRM:0 [RNE (round to nearest; ties to even)]

	Next, I spotted that the text that goes along with the 'FRM' field was
	not wrapped in the i18n markers for internationalisation, so I added
	those.

	Next, I spotted that:

	  (gdb) set $frm=0x7
	  (gdb) info registers $fflags $frm $fcsr
	  fflags         0x0      RD:0 NV:0 DZ:0 OF:0 UF:0 NX:0
	  frm            0x7      FRM:3 [RUP (Round up towards +INF)]
	  fcsr           0xe0     RD:7 NV:0 DZ:0 OF:0 UF:0 NX:0 FRM:3 [RUP (Round up towards +INF)]

	Notice that despite being a 3-bit field, FRM masks to 2-bits.
	Checking the manual I can see that the FRM field is 3-bits, and is
	defined for all 8 values.  That GDB masks to 2-bits is just a bug I
	think, so I've fixed this.

	Finally, the 'FRM' text for value 0x7 is wrong.  Currently we use the
	text 'dynamic rounding mode' for value 0x7.  However, this is not
	really correct.

	A RISC-V instruction can either encode the rounding mode within the
	instruction, or a RISC-V instruction can choose to use a global,
	dynamic rounding mode.

	So, for the rounding-mode field of an _instruction_ the value 0x7
	indicates "dynamic round mode", the instruction should defer to the
	rounding mode held in the FRM field of the $fcsr.

	But it makes no sense for the FRM of $fcsr to itself be set to
	0x7 (dynamic rounding mode), and indeed, section 11.2, "Floating-Point
	Control and Status Register" of the RISC-V manual, says that a value
	of 0x7 in the $fcsr FRM field is invalid, and if an instruction has
	_its_ round-mode set to dynamic, and the FRM field is also set to 0x7,
	then an illegal instruction exception is raised.

	And so, I propose changing the text for value 0x7 of the FRM field to
	be "INVALID[7] (Dynamic rounding mode)".  We already use the text
	"INVALID[5]" and "INVALID[6]" for the two other invalid fields,
	however, I think adding the extra "Dynamic round mode" hint might be
	helpful.

	I've added a new test that uses 'info registers' to check what GDB
	prints for the three registers related to this patch.  There is one
	slight oddity with this test - for the fflags and frm registers, the
	test accepts both the "normal" output (as described above), but also
	allows these registers to be reported as '<unavailable>'.

	The reason why I accept <unavailable> is that currently, the RISC-V,
	native Linux target advertises these registers in its target
	description, but then doesn't support reading or writing of these
	registers, this results in the registers being reported as
	unavailable.

	A later patch in this series will address this issue, and will remove
	this check for <unavailable>.

	gdb, dwarf: create symbols for template tags without names
	The following GDB behavior was also reported as a GDB bug in

	  https://sourceware.org/bugzilla/show_bug.cgi?id=28396

	I will reiterate the problem a bit and give some more information here.
	This patch closes the above mentioned bug.

	The DWARF 5 standard 2.23 'Template Parameters' reads:

	   A template type parameter is represented by a debugging information
	   entry with the tag DW_TAG_template_type_parameter.  A template value
	   parameter is represented by a debugging information entry with the tag
	   DW_TAG_template_value_parameter.  The actual template parameter entries
	   appear in the same order as the corresponding template formal
	   parameter declarations in the source progam.

	   A type or value parameter entry may have a DW_AT_name attribute, whose
	   value is a null-terminated string containing the name of the
	   corresponding formal parameter.

	So the DW_AT_name attribute for DW_TAG_template_type_parameter and
	DW_TAG_template_value_parameter is optional.

	Within GDB, creating a new symbol from some read DIE usually requires the
	presence of a DW_AT_name for the DIE (an exception here is the case of
	unnamed namespaces or the existence of a linkage name).

	This patch makes the presence of the DW_AT_name for template value/type
	tags optional, similar to the unnamed namespaces.

	For unnamed namespaces dwarf2_name simply returns the constant string
	CP_ANONYMOUS_NAMESPACE_STR '(anonymous namespace)'.  For template tags a
	case was added to the switch statement calling the
	unnamed_template_tag_name helper.  Within the scope of parent which
	the template parameter is a child of, the helper counts the position
	of the template tag within the unnamed template tags and returns
	'<unnamedNUMBER>' where NUMBER is its position.  This way we end up with
	unique names within the respective scope of the function/class/struct
	(these are the only currenltly supported template kinds within GDB and
	usually the compilers) where we discovered the template tags in.

	While I do not know of a way to bring GCC to emit template tags without
	names there is one for clang/icpx.  Consider the following example

	  template<typename A, typename B, typename C>
	  class Foo {};

	  template<typename, typename B, typename>
	  class Foo;

	  int main () {
	    Foo<double, int, float> f;
	    return 0;
	  }

	The forward declaration for 'Foo' with the missing template type names
	'A' and 'C' makes clang emit a bunch of template tags without names:

	 ...
	  <2><43>: Abbrev Number: 3 (DW_TAG_variable)
	    <44>   DW_AT_location    : 2 byte block: 91 78      (DW_OP_fbreg: -8)
	    <47>   DW_AT_name        : (indirect string, offset: 0x63): f
	    <4b>   DW_AT_decl_file   : 1
	    <4c>   DW_AT_decl_line   : 8
	    <4d>   DW_AT_type        : <0x59>
	 ...
	 <1><59>: Abbrev Number: 5 (DW_TAG_class_type)
	    <5a>   DW_AT_calling_convention: 5  (pass by value)
	    <5b>   DW_AT_name        : (indirect string, offset: 0x74): Foo<double, int, float>
	    <5f>   DW_AT_byte_size   : 1
	    <60>   DW_AT_decl_file   : 1
	    <61>   DW_AT_decl_line   : 2
	 <2><62>: Abbrev Number: 6 (DW_TAG_template_type_param)
	    <63>   DW_AT_type        : <0x76>
	 <2><67>: Abbrev Number: 7 (DW_TAG_template_type_param)
	    <68>   DW_AT_type        : <0x52>
	    <6c>   DW_AT_name        : (indirect string, offset: 0x6c): B
	 <2><70>: Abbrev Number: 6 (DW_TAG_template_type_param)
	    <71>   DW_AT_type        : <0x7d>
	 ...

	Befor this patch, GDB would not create any symbols for the read template
	tag DIEs and thus lose knowledge about them.  Breaking at the return
	statement and printing f's type would read

	  (gdb) ptype f
	  type = class Foo<double, int, float> [with B = int] {
	      <no data fields>
	  }

	After this patch GDB does generate symbols from the DWARF (with their
	artificial names:

	  (gdb) ptype f
	  type = class Foo<double, int, float> [with <unnamed0> = double, B = int,
	  <unnamed1> = float] {
	      <no data fields>
	  }

	The same principle theoretically applies to template functions.  Also
	here, GDB would not record unnamed template TAGs but I know of no visual
	way to trigger and test this changed behavior.  Template functions do
	not emit a '[with...]' list and their name generation also does not
	suffer from template tags without names.  GDB does not check whether or
	not a template tag has a name in 'dwarf2_compute_name' and thus, the
	names of the template functions are created independently of whether or
	not the template TAGs have a DW_TAT_name attribute.  A testcase has
	been added in the gdb.dwarf2 for template classes and structs.

	gdb, testsuite: adapt function_range expected name
	When writing a dwarf testcase for some C++ code I wanted to use the
	MACRO_AT_range which in turn uses the function_range proc in dwarf.exp
	to extract the bounds of 'main'.

	However, the macro failed as GDB prints the C++ 'main' with its
	arguments as 'main(int, char**)' or 'main()'.

	The reason for this is that in read.c::dwarf2_compute_name we call
	c_type_print_args on C++ functions and append their arguments to the
	function name.  This happens to all C++ functions, but is only visible
	when the function doesn't have a linkage name.

	An example might make this more clear.  Given the following code

	  >> cat c.cpp
	  int foo (int a, float b)
	  {
	    return 0;
	  }

	  int main (int argc, char **argv)
	  {
	    return 0;
	  }

	which is legal in both languages, C and C++, and compiling it with
	e.g. clang or gcc will make the disassemble command look like:

	  >> clang --version
	  clang version 10.0.0-4ubuntu1
	  ...
	  >> clang -O0 -g ./c.cpp
	  >> gdb -q ./a.out -ex "start"
	  ...
	  (gdb) disassemble main
	  Dump of assembler code for function main(int, char**):
	     0x0000000000401120 <+0>:     push   %rbp
	     0x0000000000401121 <+1>:     mov    %rsp,%rbp
	  ...
	     0x0000000000401135 <+21>:    ret
	  End of assembler dump.
	  (gdb) disassemble foo
	  Dump of assembler code for function _Z3fooif:
	     0x0000000000401110 <+0>:     push   %rbp
	     0x0000000000401111 <+1>:     mov    %rsp,%rbp
	  ...
	     0x000000000040111f <+15>:    ret
	  End of assembler dump.

	Note, that main is emitted with its arguments while for foo the linkage
	name is being printed, as also visible in its DWARF:

	  >> objdump ./a.out --dwarf=info | grep "foo" -A3 -B3
	      <2b>   DW_AT_low_pc      : 0x401110
	      <33>   DW_AT_high_pc     : 0x10
	      <37>   DW_AT_frame_base  : 1 byte block: 56         (DW_OP_reg6 (rbp))
	      <39>   DW_AT_linkage_name: (indirect string, offset: 0x39): _Z3fooif
	      <3d>   DW_AT_name        : (indirect string, offset: 0x42): foo
	      <41>   DW_AT_decl_file   : 1
	      <42>   DW_AT_decl_line   : 1
	      <43>   DW_AT_type        : <0x9a>

	Now, let's rename the C++ file and compile it as C:

	  >> mv c.cpp c.c
	  >> clang -O0 -g ./c.c
	  >> gdb -q ./a.out -ex "start'
	  ...
	  (gdb) disassemble main
	  Dump of assembler code for function main:
	     0x0000000000401120 <+0>:     push   %rbp
	     0x0000000000401121 <+1>:     mov    %rsp,%rbp
	  ...
	     0x0000000000401135 <+21>:    ret
	  End of assembler dump.
	  (gdb) disassemble foo
	  Dump of assembler code for function foo:
	     0x0000000000401110 <+0>:     push   %rbp
	     0x0000000000401111 <+1>:     mov    %rsp,%rbp
	  ...
	     0x000000000040111f <+15>:    ret
	  End of assembler dump.

	Note, for foo we did not get a linkage name emitted in DWARF, so
	it is printed by its name:

	  >> objdump --dwarf=info ./a.out | grep foo -A3 -B3
	      <2b>   DW_AT_low_pc      : 0x401110
	      <33>   DW_AT_high_pc     : 0x10
	      <37>   DW_AT_frame_base  : 1 byte block: 56         (DW_OP_reg6 (rbp))
	      <39>   DW_AT_name        : (indirect string, offset: 0x37): foo
	      <3d>   DW_AT_decl_file   : 1
	      <3e>   DW_AT_decl_line   : 1
	      <3f>   DW_AT_prototyped  : 1

	To make the macro and proc work with C++ as well, an optional argument
	list was added to the regex matching the function name in the
	disassemble command in function_range.  This does not change any used
	behavior as currently, there exists no C++ test using the proc
	function_range.

	gdb/elfread.c: Use bfd filename instead of objfile->original_name

	In some cases original_name is prefixed with gdb's working directory

	ld: pe: Fix linking against Microsoft import libraries with multiple DLLs
	Initially, since c6c37250e98f113755e0d787f7070e2ac80ce77e (in 1999),
	in order to fix linking against Microsoft import libraries, ld did
	internally rename members of such libraries. At that point, the
	criteria for being considered a Microsoft import library was that
	every archive member had the same name (no regard for exactly what
	that name was).

	This was later amended in 44dbf3639f127af46d569ad96b6242dfbc4c0a89
	(in 2003) to allow for Microsoft import libraries with intermixed
	static object files. At this point, the criteria were extended, so
	that all members following the first member named *.dll either had
	the exact same member name, or be named *.obj. (Curiously, this would
	allow members with any name if it precedes the first one named *.dll.)

	In practice, Microsoft style import libraries can contain
	members for linking against more than one DLL (built by merging
	multiple regular import libraries into one).

	Instead of trying to do validation of the whole archive before
	considering it a Microsoft style import library, relax the criteria
	for doing the member renaming: If an archive member is named *.dll
	and it contains .idata sections, assume that that member is a
	Microsoft import file, and apply the renaming scheme.

	This works for imports for any number of DLLs in the same library,
	intermixed with other static object files (regardless of their
	names), and vastly simplifies the code.

	LLVM generates Microsoft style import libraries, and Rust builds
	seem to bundle up multiple import libraries together with some
	Rust specific static objects. This fixes linking directly against
	them with ld.bfd.

	[gdb/symtab] Fix assert in set_length
	When running the included test-case, we run into:
	...
	(gdb) break _start^M
	read.h:309: internal-error: set_length: \
	  Assertion `m_length == length' failed.^M
	...

	The problem is that while there are two CUs:
	...
	$ readelf -wi debug-names-missing-cu | grep @
	  Compilation Unit @ offset 0x0:
	  Compilation Unit @ offset 0x2d:
	...
	the CU table in the .debug_names section only contains the first one:
	...
	CU table:
	[  0] 0x0
	...

	The incomplete CU table makes create_cus_from_debug_names_list set the size of
	the CU at 0x0 to the actual size of both CUs combined.

	This eventually leads to the assert, when we read the actual size from the CU
	header.

	While having an incomplete CU table in a .debug_names section is incorrect,
	we need a better failure mode than asserting.

	The easiest way to fix this is to set the length to 0 (meaning: unkown) in
	create_cus_from_debug_names_list.

	This makes the failure mode to accept the incomplete CU table, but to ignore
	the missing CU.

	It would be nice to instead reject the .debug_names index, and build a
	complete CU list, but the point where we find this out is well after
	dwarf2_initialize_objfile, so it looks rather intrusive to restart at that
	point.

	Tested on x86_64-linux.

	[gdb/tdep] Declare score-*-* target obsolete
	I tried out the script gdb/gdb_mbuild.sh, and ran into:
	...
	score-elf ...
	... configure --target=score-elf
	... make score-elf
	... run score-elf
	score-elf: gdb dumped core
	Terminated
	...

	Gdb runs into this internal error in initialize_current_architecture:
	...
	  if (! gdbarch_update_p (info))
	    internal_error (__FILE__, __LINE__,
	                    _("initialize_current_architecture: Selection of "
	                      "initial architecture failed"));
	...

	The call to gdbarch_update_p fails because commit 575b4c298a6 ("gdb: Remove
	support for S+core") removed support for the architecture.

	Fix this by adding score-*-* to the list of obsolete targets in
	gdb/configure.tgt, such that we're no longer able to build the configuration:
	...
	*** Configuration score-unknown-elf is obsolete.
	*** Support has been REMOVED.
	make: *** [Makefile:12806: configure-gdb] Error 1
	...

	Also remove the related line from the "Target Instruction Set Architectures"
	list in gdb/MAINTAINERS, such that gdb/gdb_mbuild.sh no longer tries to build
	it.

	Allow to document user-defined aliases.
	Compared to the previous version, this version fixes the comments reported by
	Tom Tromey and ensures that the 'help some-user-documented-alias'
	shows the alias definition to ensure the user understands this is an
	alias even if specifically documented.

	When using 'help ALIASNAME', GDB shows the help of the aliased command.
	This is a good default behaviour.

	However, GDB alias command allows to define aliases with arguments
	possibly changing or tuning significantly the behaviour of
	the aliased command.  In such a case, showing the help of the aliased
	command might not be ideal.

	This is particularly true when defining an alias as a set of
	nested 'with' followed by a last command to launch, such as:
	  (gdb) alias pp10 = with print pretty -- with print elements 10 -- print
	Asking 'help pp10' shows the help of the 'with' command, which is
	not particularly useful:
	  (gdb) help pp10
	  with, pp10, w
	    alias pp10 = with print pretty -- with print elements 10 -- print
	  Temporarily set SETTING to VALUE, run COMMAND, and restore SETTING.
	  Usage: with SETTING [VALUE] [-- COMMAND]
	  ....

	Such an alias can now be documented by the user:
	  (gdb) document pp10
	  >Pretty printing an expressiong, printing 10 elements.
	  >Usage: pp10 [PRINT-COMMAND-OPTIONS] EXP
	  >See 'help print' for more information.
	  >end
	  (gdb) help pp10
	    alias pp10 = with print pretty -- with print elements 10 -- print
	  Pretty printing an expressiong, printing 10 elements.
	  Usage: pp10 [PRINT-COMMAND-OPTIONS] EXP
	  See 'help print' for more information.
	  (gdb)

	When a user-defined alias is documented specifically, help and apropos
	use the provided alias documentation instead of the documentation of
	the aliased command.

	Such a documented alias is also not shown anymore in the help of the
	aliased command, and the alias is not listed anymore in the help
	of the aliased command.  In particular for cases such as pp10 example above,
	indicating that pp10 is an alias of the 'with' command is confusing.

	x86: Ignore protected visibility in shared libraries on Solaris
	On x86, the PLT entry in executable may be used as function address for
	functions in shared libraries.  If functions are protected, the function
	address used in executable can be different from the function address
	used in shared library.  This will lead to incorrect run-time behavior
	if function pointer equality is needed.  By default, x86 linker issues
	an error in this case.

	On Solaris, linker issued an error for

	struct tm *tb = (kind == CPP_time_kind::FIXED ? gmtime : localtime) (&tt);

	where gmtime is a protected function in libc.so.  Use gmtime's PLT entry
	in executable as function address is safe since function pointer equality
	isn't needed.  Ignore protected visibility in shared libraries on Solaris
	to disable linker error.  If function pointer equality is needed, linker
	will silently generate executable with incorrect run-time behavior on
	Solaris.

	Implement target async for Windows
	This implements target async for Windows.  The basic idea is to have
	the worker thread block in WaitForDebugEvent, then notify the event
	loop when an event is seen.  In a few situations, this blocking
	behavior is undesirable, so the functions passed to do_synchronously
	are changed to return a boolean indicating which behavior is needed.

2022-08-22  Tom Tromey  <tromey@adacore.com>

	Move some Windows operations to worker thread
	On Windows, certain debugging APIs can only be called from the thread
	that started (or attached) to the inferior.  Also, there is no way on
	Windows to wait for a debug event in addition to other events.
	Therefore, in order to implement target async for Windows, gdb will
	have to call some functions in a worker thread.

	This patch implements the worker thread and moves the necessary
	operations there.  Target async isn't yet implemented, so this patch
	does not cause any visible changes.

	Avoid crash with Ravenscar tasks
	When using Ravenscar, gdb can crash if the user sets a breakpoint very
	early in task startup.  This happens because gdb thinks the runtime is
	initialized, but in practice the particular task isn't sufficiently
	initialized.  This patch avoids the issue by turning an assertion into
	an early return.

	I tested this using the AdaCore internal test suite.  I don't know how
	to test Ravenscar using the FSF test suite.

	symbols for bfd_simple_get_relocated_section_contents
	If symbols are provided by the caller of this function they are
	passed on to bfd_get_relocated_section_contents.  No surprises there.
	It gets a little weird if they are not provided.  In that case they
	are read from the bfd by _bfd_generic_link_add_symbols, and global
	symbols are added to the generic linker hash table.  Global symbols
	are not added to the linker hash table if symbols *are* provided.  Now
	the linker hash table symbols are not used by the generic
	bfd_get_relocated_section_conents, and also not by most target
	versions when called from bfd_simple_get_relocated_section_contents
	except for symbols like "_gp".  So it mostly doesn't matter whether
	symbols are in the linker hash table, but it's odd that there is a
	difference.  We could always add them, but I'm inclined to think that
	is unnecessary work so this patch always leaves them out.

	Also, symbols are canonicalized and written into a malloc'd buffer.
	The buffer isn't freed, see commit 8e16317ca5eb.  I don't know whether
	that matters any more, but in any case I can't see why we need another
	copy of the symbols when _bfd_generic_link_read_symbols has already
	cached symbols.

		* simple.c (bfd_simple_get_relocated_section_contents): If not
		provided, read symbols via bfd_generic_link_read_symbols.  Do
		not create another copy of symbols.  Tidy failure exits.
		Minor tidy of bfd_get_relocated_section_contents and
		bfd_get_full_section_contents arguments.

	gdb/testsuite: re-compile entry-value-typedef .S files with -fPIE
	As Luis pointed out here [1], the AArch64 variant of the test doesn't
	work on systems that use PIE by default.  For example, on this Debian
	11:

	    $ make check TESTS="gdb.dwarf2/entry-value-typedef.exp"
	    gdb compile failed, /usr/bin/ld: /tmp/ccJE8ZSr.o: relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `_ZNSsD1Ev@@GLIBCXX_3.4' which may bind externally can not be used when making a shared object; recompile with -fPIC
	    /usr/bin/ld: /tmp/ccJE8ZSr.o(.text+0x38): unresolvable R_AARCH64_ADR_PREL_PG_HI21 relocation against symbol `_ZNSsD1Ev@@GLIBCXX_3.4'

	This is because entry-value-typedef-aarch64.S was generated on an old
	system that does not generate position-independent code by default, but
	the system the test runs on tries to link the test executable as
	position-independent.  Fix this by regenerating the same binary on the
	same system as the original one, but with -fPIE this time.  Do the same
	for the amd64 binary, although this one was already position-independent
	so the generated code doesn't change.

	With this patch applied, the test passes on the Debian 11 AArch64
	system.

	gdb, testsuite: Adapt gdb.base/callfuncs.exp for new clang warning.
	Clang 15.0.0 enabled the warning for deprecated non-prototype functions
	by default: https://reviews.llvm.org/D122895
	Callfuncs.exp is impacted and won't run due to new warnings:

	callfuncs.c:339:5: warning: a function declaration without a prototype is
	deprecated in all versions of C and is not supported in C2x
	[-Wdeprecated-non-prototype]
	int t_float_values (float_arg1, float_arg2)

	This patch disables those warnings with -Wno-deprecated-non-prototype.
	Removing the test for deprecated syntax would also be an option. But I will
	leave that up for others to decide/implement.

2022-08-19  Felix Willgerodt  <felix.willgerodt@intel.com>

	gdb, testsuite: Enable testcases that suppress specific warnings, for icc/icx.
	To cite gdb.exp:
	Some C/C++ testcases unconditionally pass -Wno-foo as additional
	options to disable some warning.  That is OK with GCC, because
	by design, GCC accepts any -Wno-foo option, even if it doesn't
	support -Wfoo.  Clang however warns about unknown -Wno-foo by
	default, unless you pass -Wno-unknown-warning-option as well.
	We do that here, so that individual testcases don't have to
	worry about it.

	This patch adds the same option that already exists for clang for icx and
	adds the equivalent icc option.

	The problem is that the type that gets passed down to
	dwarf_expr_context::fetch_result (the type of a variable of which we're
	trying to read the entry value) is a typedef whose size has never been
	computed yet (check_typedef has never been called on it).  As we get in
	the DWARF_VALUE_STACK case (line 1028 of dwarf2/expr.c), the `len`
	variable is therefore set to 0, instead of the actual type length.  We
	then call allocate_value on subobj_type, which does call check_typedef,
	so the length of the typedef gets filled in at that point.  We end up
	passing to the copy function a source array view of length 0 and a
	target array view of length 4, and the assertion fails.

	Fix this by calling check_typedef on both type and subobj_type at the
	beginning of fetch_result.

	I tried writing a test for this using the DWARF assembler, but I haven't
	succeeded.  It's possible that we need to get into this specific code
	path (value_of_dwarf_reg_entry and all) to manage to get to
	dwarf_expr_context::fetch_result with a typedef type that has never been
	resolved.  In all my attempts, the typedef would always be resolved
	already, so the bug wouldn't show up.

	As a fallback, I made a gdb.dwarf2 test with compiler-generated .S
	files.  I don't particularly like those, but I think it's better than no
	test.  The .cpp source code is the smallest reproducer I am able to make
	from the reproducer given in the bug (thanks to Pedro for suggestions on
	how to minimize it further than I had).  Since I tested on both amd64
	and aarch64, I added versions of the test for these two architectures.

	[aarch64] Remove handling of ADR/ADRP from prologue analyzer
	As reported by Tom in https://sourceware.org/pipermail/gdb-patches/2022-August/191357.html,
	the aarch64 prologue analyzer considers the adrp instruction in the
	gdb.dwarf2/dw2-dir-file-name.exp testcase to be part of a prologue.

	The function has no prologue though, and it only loads the volatile variable
	from memory.  GDB should not skip any instructions in this case.

	Doing some archaeology, it seems handling for adr/adrp in prologues was
	included with the original aarch64 port.  It might've been an oversight.

	In the particular case of gdb.dwarf2/dw2-dir-file-name.exp, the analyzer skips
	a couple instructions and leaves us in a nice spot where the address to the
	variable "v" is already in w0. But no prologues exists.

	Notice that register tpidr disappeared when vg (which holds the vector
	length) changed from 8 to 4.  The tpidr register is provided by the
	org.gnu.gdb.aarch64.tls feature.

	This happens because the code that searches for a new gdbarch to match the
	new vector length in aarch64_linux_nat_target::thread_architecture doesn't

	gdbsupport/event-loop: add a timeout parameter to gdb_do_one_event
	Since commit b2d8657, having a per-interpreter event/command loop is not
	possible anymore.

	As Insight uses a GUI that has its own event loop, gdb and GUI event
	loops have then to be "merged" (i.e.: work together). But this is
	problematic as gdb_do_one_event is not aware of this alternate event
	loop and thus may wait forever.

	A solution is to delegate GUI events handling to the gdb events handler.
	Insight uses Tck/Tk as GUI and the latter offers a "notifier" feature to
	implement such a delegation. The Tcl notifier spec requires the event wait
	function to support a timeout parameter. Unfortunately gdb_do_one_event
	does not feature such a parameter.
	This timeout cannot be implemented externally with a gdb timer, because
	it would become an event by itself and thus can cause a legitimate event to
	be missed if the timeout is 0.
	Tcl implements "idle events" that are (internally) triggered only when no
	other event is pending. For this reason, it can call the event wait function
	with a 0 timeout quite often.

	This patch implements a wait timeout to gdb_do_one_event. The initial
	pending events monitoring is performed as before without the possibility
	to enter a wait state. If no pending event has been found during this
	phase, a timer is then created for the given timeout in order to re-use
	the implemented timeout logic and the event wait is then performed.
	This "internal" timer only limits the wait time and should never be triggered.
	It is deleted upon gdb_do_one_event exit.

	The new parameter defaults to "no timeout" (-1): as it is used by Insight
	only, there is no need to update calls from the gdb source tree.

	x86: move / quiesce pre-386 non-16-bit warning
	Emitting this warning for every insn, including ones having actual

	just once on the first insn after .arch may have changed the things, and
	move the warning to output_insn(). (I didn't want to go as far as
	checking whether the .arch actually turned off the i386 bit, but doing

	gdb/riscv: fix gdb.arch/riscv-unwind-long-insn.exp on RV64
	I noticed that the gdb.arch/riscv-unwind-long-insn.exp test was
	failing when run on a 64-bit RISC-V target.

	The problem was that GDB was failing to stop after a finish command,
	and was then running to an unexpected location.

	The reason GDB failed to stop at the finish breakpoint was that the
	frame-id of the inferior, when we reached the finish breakpoint,
	didn't match the expected frame-id that was stored on the breakpoint.

	The reason for this mismatch was that the assembler code that is
	included in this test, was written only taking 32-bit RISC-V into
	account, as a result, the $fp register was being corrupted, and this
	was causing the frame-id mismatch.

	Specifically, the $fp register would end up being sign-extended from
	32 to 64 bits.  If the expected $fp value has some significant bits
	above bit 31 then the computed and expected frame-ids would not match.

	To fix this I propose merging the two .s files into a single .S file,
	and making use of preprocessor macros to specialise the file for the
	correct size of $fp.  There are plenty of existing tests that already
	make use of preprocessor macros in assembler files, so I assume this
	approach is fine.

	Once I'd decided to make use of preprocessor macros to solve the 32/64
	bit issue, then I figured I might as well merge the two test assembler
	files, they only differed by a single instruction.

	With this change in place I now see this test fully passing on 32 and
	64 bit RISC-V targets.

	PR29495, rewrite_elf_program_header looping
	This patch, in order of significance:
	1) Replaces some macros with inline functions.
	2) Those inline functions catch and avoid arithmetic overflows when
	   comparing addresses.
	3) When assigning sections to segments (IS_SECTION_IN_INPUT_SEGMENT)
	   use bed->want_p_paddr_set_to_zero to decide whether lma vs p_paddr
	   or vma vs p_vaddr should be tested.  When remapping, use the same
	   test, and use is_note rather than the more restrictive
	   IS_COREFILE_NOTE.

	It's important that the later tests not be more restrictive.  If they
	are it can lead to the situation triggered by the testcases, where a
	section seemingly didn't fit and thus needed a new mapping.  It didn't
	fit the new mapping either, and this repeated until memory exhausted.

	disambiguation purposes in AT&T syntax. All of these gorups follow
	certain patterns. Introduce "xy" and "xyz" templates to reduce
	redundancy.

	To facilitate using a uniform name for both AVX and AVX512, further
	introduce a means to purge a previously defined template: A standalone
	<name> will be recognized to have this effect.

	Note that in the course of the conversion VFPCLASSPH is properly split
	to separate AT&T and Intel syntax forms, matching VFPCLASSP{S,D} and
	yielding the intended "ambiguous operand size" diagnostic in Intel mode.

	Note that in the course of the conversion
	- the AVX VPEXTRW template which is not being touched needs to remain
	  ahead of the new "combined" ones, as (a) this should be tried first
	  when matching insns against templates and (b) its Load attributes
	  requires it to be first,

	  insns with multiple forms (i.e. the same Cpu64 attributes on {,V}MOVQ,
	  {,V}PEXTRQ, and  {,V}PINSRQ are useful to keep),

	x86: template-ize packed/scalar vector floating point insns

	For element-size Disp8 shift generalize i386-gen's broadcast size
	determination, allowing Disp8MemShift to be specified without an operand
	in the affected templated templates. While doing the adjustment also
	eliminate an unhelpful (lost information) diagnostic combined with a use
	after free in what is now get_element_size().

	Note that in the course of the conversion
	- the AVX512F form of VMOVUPD has a stray (leftover) Load attribute
	  dropped,
	- VMOVSH has a benign IgnoreSize added (the attribute is still strictly
	  necessary for VMOVSD, and necessary for VMOVSS as long as we permit
	  strange combinations like "-march=i286+avx"),

	gdb/riscv: improve a comment about fcsr, fflags, and frm registers
	There's a comment in riscv-tdep.c that explains some of the background
	about how we check for the fcsr, fflags, and frm registers within a
	riscv target description.

	This comment (and the functionality it describes) relates to how QEMU
	advertises these registers within its target description.

	Unfortunately, QEMU includes these three registers in both the fpu and
	crs target description features.  To work around this GDB uses one of
	the register declarations, and ignores the other, this means the GDB
	user sees a single copy of each register, and things just work.

	When I originally wrote the comment I thought it didn't matter which
	copy of the register GDB selected, the fpu copy or the csr copy, so
	long as we just used one of them.  The comment reflected this belief.

	Upon further investigation, it turns out I was wrong.  GDB has to use
	the csr copy of the register.  If GDB tries to use the register from
	the fpu feature then QEMU will return an error when GDB tries to read
	or write the register.

	Luckily, the code within GDB (currently) will always select the csr
	copy of the register, so nothing is broken, but the comment is wrong.
	This commit updates the comment to better describe what is actually
	going on.

	Of course, I should probably also send a patch to QEMU to fix up the
	target description that is sent to GDB.

	Don't use bfd_vma in readelf.c
	This replaces bfd_vma with uint64_t in readelf, defines BFD64

	removes quite a few now unnecessary casts.

	Don't use bfd_size_type in readelf.c and dwarf.c
	Replacing bfd_size_type with dwarf_size_type or uint64_t is mostly
	cosmetic.  The point of the change is to avoid use of a BFD type
	in readelf, where we'd like to keep as independent of BFD as
	possible.  Also, the patch is a step towards using standard types.

	Replace elf_vma with uint64_t
	This patch replaces all uses of elf_vma with uint64_t, removes

	...

	And because the line table info is rudamentary:
	...

	File name                    Line number    Starting address    View    Stmt

	...
	the address does not fall at an actual line, so the breakpoint is shown with
	address, both when setting it and hitting it.

	when running the test-case with aarch64-linux, we have similarly:
	...
	(gdb) break compdir_missing__ldir_missing__file_basename^M
	Breakpoint 2 at 0x400618: file tmp-dw2-dir-file-name.c, line 999.^M
	...
	due to the architecture-specific prologue skipper starting at 0x400610 and
	skipping past two insns, to 0x400618:
	...
	0000000000400610 <compdir_missing__ldir_missing__file_basename>:
	  400610:       90000100        adrp    x0, 420000 <__libc_start_main@GLIBC_2.17>

	  400630:       d65f03c0        ret
	...

	But interestingly, the aarch64 architecture-specific prologue skipper is
	wrong.  There is no prologue, and the breakpoint should be set at 0x400610.

	By using "break *compdir_missing__ldir_missing__file_basename"
	we can get the breakpoint set at 0x400610:
	...
	(gdb) break *compdir_missing__ldir_missing__file_basename^M
	Breakpoint 2 at 0x400610: file tmp-dw2-dir-file-name.c, line 999.^M
	...
	and make the test-case independent of prologue analysis.

	This requires us to update the expected patterns.

	The fix ensures that once the aarch64 architecture-specific prologue skipper
	will be fixed, this test-case won't start failing.

	Tested on x86_64-linux.

	gdb/varobj: Only re-evaluate invalid globals during re_set
	When doing varobj_re_set, we currently try to recreate floating varobj.
	This was introduced by 4e969b4f0128 "Re-evaluate floating varobj as part
	of varobj_invalidate" to deal with use a after free issue.  However
	since bc20e562ec0 "Fix use after free in varobj" we now ensure that we
	never have dangling pointers so this all recreation is not strictly
	needed anymore for floating varobjs.

	This commit proposes to remove this recreation process for floating
	varobjs.

	gdb/varobj: Reset varobj after relocations have been computed
	[This patch is a followup to the discussion in
	https://sourceware.org/pipermail/gdb-patches/2022-August/191188.html]

	PR/29426 shows failures when running the gdb.mi/mi-var-invalidate-shlib
	test when using a compiler which does not produce a PIE executable by
	default.

	In the testcase, a varobj is created to track a global variable, and
	then the main binary is reloaded in GDB (using the file command).

	During the load of the new binary, GDB tries to recreate the varobj to
	track the global in the new binary (varobj_invalidate_iter).  At this
	point, the old process is still in flight.  So when we try to access to
	the value of the global, in a PIE executable we only have access to the
	unrelocated address (the objfile's text_section_offset () is 0).  As a
	consequence down the line read_value_memory fails to read the unrelated
	address, so cannot evaluate the value of the global.  Note that the
	expression used to access to the global’s value is valid, so the varobj
	can be created.  When using a non PIE executable, the address of the
	global GDB knows about at this point does not need relocation, so
	read_value_memory can access the (old binary’s) value.

	So at this point, in the case of a non-PIE executable the value field is
	set, while it is cleared in the case of PIE executable.  Later when the
	test issues a "-var-update global_var", the command sees no change in
	the case of the non-PIE executable, while in the case of the PIE
	executable install_new_value sees that value changes, leading to a
	different output.

	This patch makes sure that, as we do for breakpoints, we wait until
	relocation has happened before we try to recreate varobjs.  This way we
	have a consistent behavior between PIE and non-PIE binaries.

	Tested on x86_64-linux.

	gdb/varobj: Do not invalidate locals in varobj_invalidate_iter
	The varobj_invalidate_iter function has logic to invalidate any local
	varobj it can find.  However since bc20e562ec0 "gdb/varobj: Fix use
	after free in varobj" all varobj containing references to an objfile are
	cleared when the objfile goes out of scope.  This means that at this
	point any local varobj seen by varobj_invalidate_iter either has
	already been invalidated by varobj_invalidate_if_uses_objfile or only
	contains valid references and there is no reason to invalidate it.

	This patch proposes to remove this unnecessary invalidation and adds a
	testcase which exercises a scenario where a local varobj can legitimately
	survive a call to varobj_invalidate_iter.

	At this point the varobj_invalidate and varobj_invalidate_iter seem
	misnamed since they deal with re-creating invalid objects and do not do
	invalidation, but this will be fixed in a following patch.

	Tested on x86_64-linux.

	PR29466, APP/NO_APP with .linefile
	Commit 53f2b36a54b9 exposed a bug in sb_scrub_and_add_sb that could
	result in losing input.  If scrubbing results in expansion past the
	holding capacity of do_scrub_chars output buffer, then do_scrub_chars
	stashes the extra input for the next call.  That call never came
	because sb_scrub_and_add_sb wrongly decided it was done.  Fix that by
	allowing sb_scrub_and_add_sb to see whether there is pending input.
	Also allow a little extra space so that in most cases we won't need
	to resize the output buffer.

	sb_scrub_and_add_sb also limited output to the size of the input,
	rather than the actual output buffer size.  Fixing that resulted in a
	fail of gas/testsuite/macros/dot with an extra warning: "end of file
	not at end of a line; newline inserted".  OK, so the macro in dot.s
	really does finish without end-of-line.  Apparently the macro
	expansion code relied on do_scrub_chars returning early.  So fix that
	too by adding a newline if needed in macro_expand_body.

	gdb/mi: fix breakpoint script field output
	The "script" field, output whenever information about a breakpoint with
	commands is output, uses wrong MI syntax.

	    $ ./gdb -nx -q --data-directory=data-directory -x script -i mi
	    =thread-group-added,id="i1"
	    =breakpoint-created,bkpt={number="1",type="breakpoint",disp="keep",enabled="y",addr="0x000000000000111d",func="main",file="test.c",fullname="/home/simark/build/binutils-gdb-one-target/gdb/test.c",line="3",thread-groups=["i1"],times="0",original-location="main"}
	    =breakpoint-modified,bkpt={number="1",type="breakpoint",disp="keep",enabled="y",addr="0x000000000000111d",func="main",file="test.c",fullname="/home/simark/build/binutils-gdb-one-target/gdb/test.c",line="3",thread-groups=["i1"],times="0",script={"aaa","bbb","ccc"},original-location="main"}
	    (gdb)
	    -break-info
	    ^done,BreakpointTable={nr_rows="1",nr_cols="6",hdr=[{width="7",alignment="-1",col_name="number",colhdr="Num"},{width="14",alignment="-1",col_name="type",colhdr="Type"},{width="4",alignment="-1",col_name="disp",colhdr="Disp"},{width="3",alignment="-1",col_name="enabled",colhdr="Enb"},{width="18",alignment="-1",col_name="addr",colhdr="Address"},{width="40",alignment="2",col_name="what",colhdr="What"}],body=[bkpt={number="1",type="breakpoint",disp="keep",enabled="y",addr="0x000000000000111d",func="main",file="test.c",fullname="/home/simark/build/binutils-gdb-one-target/gdb/test.c",line="3",thread-groups=["i1"],times="0",script={"aaa","bbb","ccc"},original-location="main"}]}
	    (gdb)

	In both the =breakpoint-modified and -break-info output, we have:

	     script={"aaa","bbb","ccc"}

	According to the output syntax [1], curly braces means tuple, and a
	tuple contains key=value pairs.  This looks like it should be a list,
	but uses curly braces by mistake.  This would make more sense:

	    script=["aaa","bbb","ccc"]

	Fix it, keeping the backwards compatibility by introducing a new MI
	version (MI4), in exactly the same way as was done when fixing
	multi-locations breakpoint output in [2].

	 - Add a fix_breakpoint_script_output uiout flag.  MI uiouts will use
	   this flag if the version is >= 4.
	 - Add a fix_breakpoint_script_output_globally variable and the
	   -fix-breakpoint-script-output MI command to set it, if frontends want
	   to use the fixed output for this without using the newer MI version.
	 - When emitting the script field, use list instead of tuple, if we want
	   the fixed output (depending on the two criteria above)

	gdb/riscv: implement cannot_store_register gdbarch method
	The x0 (zero) register is read-only on RISC-V.  Implement the
	cannot_store_register gdbarch method to tell GDB this.

	Without this method GDB will try to write to x0, and relies on the
	target to ignore such writes.  If you are using a target that
	complains (or throws an error) when writing to x0, this change will
	prevent this from happening.

	The gdb.arch/riscv-reg-aliases.exp test exercises writing to x0, and
	will show the errors when using a suitable target.

	Disable year 2038 support on 32-bit hosts by default
	With a recent import of gnulib, code has been pulled that tests and enables
	64-bit time_t by default on 32-bit hosts that support it.

	Although gdb can use the gnulib support, bfd doesn't use gnulib and currently
	doesn't do these checks.

	As a consequence, if we have a 32-bit host that supports 64-bit time_t, we'll
	have a mismatch between gdb's notion of time_t and bfd's notion of time_t.

	This will lead to mismatches in the struct stat size, leading to memory
	corruption and crashes.

	This patch disables the year 2038 check for now, which makes things work
	reliably again.

	I'd consider this a temporary fix until we have proper bfd checks for the year
	2038, if it makes sense.  64-bit hosts seems to be more common these days, so
	I'm not sure how important it is to have this support enabled and how soon
	we want to enable it.

	Thoughts?

	gas/Dwarf: properly skip zero-size functions
	PR gas/29451

	While out_debug_abbrev() properly skips such functions, out_debug_info()
	mistakenly didn't. It needs to calculate the high_pc expression ahead of
	time, in order to skip emitting any data for the function if the value
	is zero.

	The one case which would still leave a zero-size entry is when
	symbol_get_obj(symp)->size ends up evaluating to zero. I hope we can
	expect that to not be the case, otherwise we'd need to have a way to
	post-process .debug_info contents between resolving expressions and
	actually writing the data out to the file. Even then it wouldn't be
	entirely obvious in which way to alter the data.

	bfd: Add support for LoongArch64 EFI (efi-*-loongarch64).
	This adds support for efi-loongarch64 by virtue of adding a new PEI target
	pei-loongarch64.  This is not a full target and only exists to support EFI at
	this time.

	This means that this target does not support relocation processing and is mostly
	a container format.  This format has been added to elf based loongarch64 targets
	such that efi images can be made natively on Linux.

	However this target is not valid for use with gas but only with objcopy.

	We should't limit addresses to 32-bits for 64-bit vma, otherwise there will be
	"RVA truncated" error when using objcopy on loongarch64.

	With these changes the resulting file is recognized as an efi image.

	Any magic number is based on the Microsoft PE specification [1].

	The test results are as follows:

	gdb/riscv/testsuite: fix failures in gdb.arch/riscv-reg-aliases.exp
	When running on a native RISC-V Linux target I currently see failures
	in the gdb.arch/riscv-reg-aliases.exp test like this:

	  set $ft0.float = 501
	  (gdb) PASS: gdb.arch/riscv-reg-aliases.exp: write non-zero value to ft0
	  p/d $ft0.float
	  $263 = 1140490240
	  (gdb) FAIL: gdb.arch/riscv-reg-aliases.exp: read ft0 after non-zero write to ft0

	This test started failing after this commit:

	  commit 56262a931b7ca8ee3ec9104bc7e9e0b40cf3d64e
	  Date:   Thu Feb 17 13:43:59 2022 -0700

	      Change how "print/x" displays floating-point value

	The problem is that when 501 is written to $ft0.float the value is
	converted to floating point format and stored in the register.  Prior
	to the above commit printing with /x and /d would first extract the
	value as a float, and then convert the value to an integer for
	display.  After the above commit GDB now uses the raw register value
	when displaying /x and /d, and so we see this behaviour:

	  (gdb) info registers $ft0
	  ft0            {float = 501, double = 5.6347704700123827e-315}	(raw 0x0000000043fa8000)
	  (gdb) p/f $ft0.float
	  $1 = 501
	  (gdb) p/d $ft0.float
	  $2 = 1140490240
	  (gdb) p/x $ft0.float
	  $3 = 0x43fa8000

	To fix this test I now print the float registers using the /f format
	rather than /d.  With this change the test now passes.

	gdb/gdbserver: LoongArch: Improve implementation of fcc registers
	The current implementation of the fcc register is referenced to the
	user_fp_state structure of the kernel uapi [1].

	struct user_fp_state {
		uint64_t    fpr[32];
		uint64_t    fcc;
		uint32_t    fcsr;
	};

	But it is mistakenly defined as a 64-bit fputype register, resulting
	in a confusing output of "info register".

	According to "Condition Flag Register" in "LoongArch Reference Manual"
	[2], there are 8 condition flag registers of size 1. Use 8 registers of
	uint8 to make it easier for users to view the fcc register groups.

	Fix-for-multiple-thread-detection-in-AIX.
	In AIX multiple threads were not added. This patch is a fix for the same

	When we create a pthread debug session we have callbacks to read
	symbols and memory.  One of those call backs is pdc_read_data.

	Before we come into aix-thread wait() we switch to no thread and
	therefore the current thread is null.

	When we get into pdc_read_data we have a dependency that we need to
	be in the correct current thread that has caused an event of new
	thread, inorder to read memory.

	Hence we switch to the correct thread.

	This is done by passing the pid in the pthdb_user_t user_current_pid
	parameter in every call back.

	x86-64: adjust MOVQ to/from SReg attributes
	It is unclear to me why the corresponding MOV (no Q suffix) can be
	issued without REX.W, but MOVQ has to have that prefix (bit). Add
	NoRex64 and in exchange drop Size64.

	x86: adjust MOVSD attributes
	The non-SSE2AVX form of the SIMD variant of the instruction needlessly
	has the (still multi-purpose) IgnoreSize attribute. All other similar
	SSE2 insns use NoRex64 instead. Make this consistent, noting that the
	SSE2AVX form can't have the same change made - there the memory operand
	doesn't at the same time permit RegXMM (which logic uses when deciding
	whether a Q suffix is okay outside of 64-bit mode).

	x86: fold AVX VGATHERDPD / VPGATHERDQ
	While the other three variants each differ in attributes and hence can't
	be folded, these two pairs actually can be (and were previously
	overlooked). This effectively matches their AVX512VL counterparts, which
	are also expressed as a single template.

	x86: allow use of broadcast with X/Y/Z-suffixed AVX512-FP16 insns
	While the x/y/z suffix isn't necessary to use in this case, it is still
	odd that these forms don't support broadcast (unlike their AVX512F /
	AVX512DQ counterparts). The lack thereof can e.g. make macro-ized
	programming more difficult.

	x86/Intel: split certain AVX512-FP16 VCVT*2PH templates
	One more place where pre-existing templates should have been taken as a
	basis: In Intel syntax we want to consistently issue an "ambiguous
	operand size" error when a size-less memory operand is specified for an
	insn where register use alone isn't sufficient for disambiguation.

	[gdb/testsuite] Add support for .debug_names in dwarf assembler
	Add:
	- support for a per-module .debug_names section in the dwarf assembler, and
	- a test-case excercising this new functionality.

	A per-module .debug_names section needs to have an entry in the CU list for
	each CU in the module, which is made more difficult by two things:
	- linking in other objects, which may contain additional CUs
	  (typically the case on openSUSE), and
	- adding dummy CUs in the dwarf assembler.
	We handle this by:
	- compiling with -nostartfiles (so the test-case contains _start rather than
	  main), and
	- disabling the dummy CU generation for the test-case.

	I've kept things simple by having the test-case specify the hash value, rather
	than adding that functionality in the dwarf assembler.

	Also I've kept the bucket count to 1, which makes it trivial to satisfy the
	requirement that "the symbol is entered into a bucket whose index is the hash
	value modulo bucket_count".

	The readelf dump of the .debug_names section from the test-case looks like:
	...
	Version 5
	Augmentation string: 47 44 42 00  ("GDB")
	CU table:
	[  0] 0x0

	TU table:

	Foreign TU table:

	Used 1 of 1 bucket.
	Out of 2 items there are 1 bucket clashes (longest of 1 entries).

	Symbol table:
	[  0] #eddb6232 _start: <1> DW_TAG_subprogram DW_IDX_compile_unit=0
	[  1] #0b888030 int: <2> DW_TAG_base_type DW_IDX_compile_unit=0
	...

	[gdb] Add unit test for gdb::sequential_for_each
	With commit 18a5766d09c ("[gdbsupport] Add sequential_for_each") I added a

	[gdb/symtab] Use task size in parallel_for_each in dwarf2_build_psymtabs_hard
	In dwarf2_build_psymtabs_hard, we use a parallel_for_each to distribute CUs
	over threads.

	Ensuring a fair distribution over the worker threads and main thread in terms
	of number of CUs might not be the most efficient way, given that CUs can vary
	in size.

	Fix this by using per_cu->get_length () as the task size.

	I've used this experiment to verify the performance impact:
	...
	$ for n in $(seq 1 10); do \
	    time gdb -q -batch ~/firefox/libxul.so-93.0-1.1.x86_64.debug \
	    2>&1 \
	    | grep "real:"; \
	  done
	...
	and without the patch got:
	...
	real: 4.71
	real: 4.88
	real: 4.29
	real: 4.30
	real: 4.65
	real: 4.27
	real: 4.27

	real: 3.69
	real: 3.74

	real: 3.74

	so that seems a reasonable improvement.

	With parallel_for_each_debug set to true, we get some more detail about

	Introduce gdb::make_function_view
	This adds gdb::make_function_view, which lets you create a function
	view from a callable without specifying the function_view's template
	parameter.  For example, this:

	    auto lambda = [&] (int) { ... };
	    auto fv = gdb::make_function_view (lambda);

	instead of:

	    auto lambda = [&] (int) { ... };
	    gdb::function_view<void (int)> fv = lambda;

	It is particularly useful if you have a template function with an
	optional function_view parameter, whose type depends on the function's
	template parameters.  Like:

	    template<typename T>
	    void my_function (T v, gdb::function_view<void(T)> callback = nullptr);

	For such a function, the type of the callback argument you pass must
	already be a function_view.  I.e., this wouldn't compile:

	    auto lambda = [&] (int) { ... };
	    my_function (1, lambda);

	With gdb::make_function_view, you can write the call like so:

	    auto lambda = [&] (int) { ... };
	    my_function (1, gdb::make_function_view (lambda));

	Unit tests included.

	Tested by building with GCC 9.4, Clang 10, and GCC 4.8.5, on x86_64
	GNU/Linux, and running the unit tests.

	Use registry in gdbarch
	gdbarch implements its own registry-like approach.  This patch changes
	it to instead use registry.h.  It's a rather large patch but largely
	uninteresting -- it's mostly a straightforward conversion from the old
	approach to the new one.

	The main benefit of this change is that it introduces type safety to
	the gdbarch registry.  It also removes a bunch of code.

	One possible drawback is that, previously, the gdbarch registry
	differentiated between pre- and post-initialization setup.  This
	doesn't seem very important to me, though.

	Allow registry to refer to const types
	So far, the registry hasn't been used to refer to a 'const' type, but

	method.

	[gdb/testsuite] Fix ERROR in gdb.base/watchpoint-unaligned.exp
	In PR23888 an error is reported:
	...
	ERROR: tcl error sourcing watchpoint-unaligned.exp.
	ERROR: expected boolean value but got ""
	    while executing
	"if {$wpnum} {
	...

	This presumably happens when:
	- skip_hw_watchpoint_tests returns 0 meaning hw watchpoints are supported
	- gdb fails to set a hw watchpoint and instead sets a sw watchpoint

	That particular situation is handled for arm:
	...
	    -re "Watchpoint (\[0-9\]+): .*\r\n$gdb_prompt $" {
	        if {[istarget "arm*-*-*"]} {
	            untested $test
	            set wpnum 0
	        }
	    }
	...
	but not for any other targets so wpnum remains "", triggering the ERROR.

	Possibly this has been fixed for powerpc by commit 8d4e4d13afb ("gdb Power 9
	add test for HW watchpoint support."), but it's still possible for other
	targets.

	Fix this by:
	- initializing wpnum to 0 instead of ""
	- signalling the failure to set a hw watchpoint by a fail

	Tested on x86_64-linux, also by adding:
	...
	gdb_test_no_output "set can-use-hw-watchpoints 0"
	...
	and verifying that it triggers the fail.

	Don't use BFD_VMA_FMT in binutils
	BFD_VMA_FMT can't be used in format strings that need to be
	translated, because the translation won't work when the type of
	bfd_vma differs from the machine used to compile .pot files.  We've
	known about this for a long time, but patches slip through review.

	So just get rid of BFD_VMA_FMT, instead using the appropriate PRId64,
	PRIu64, PRIx64 or PRIo64 and SCN variants for scanf.  The patch is
	mostly mechanical, the only thing requiring any thought is casts
	needed to preserve PRId64 output from bfd_vma values, or to preserve

	Re: Get rid of fprintf_vma and sprintf_vma
	Commit f493c2174e messed the formatting in linker map files,
	particularly for 32-bit builds where a number of tests using map files
	regressed.  I should have noticed the BFD64 conditional printing of
	spaces to line up output due to the original %V printing hex vmas with
	16 digits when BFD64 and 8 digits when not.  Besides that, it is nicer
	to print 32-bit vmas for 32-bit targets.  So change %V back to be
	target dependent, now using bfd_sprintf_vma.  Since minfo doesn't
	return the number of chars printed, that means some places that
	currently use %V must instead sprintf to a buffer in order to find the
	length printed.

	Use unique_ptr to destroy per-bfd object
	In some cases, the objfile owns the per-bfd object.  This is yet
	another object that can sometimes be destroyed before the registry is
	destroyed, possibly reslting in a use-after-free.  Also, I noticed
	that the condition for deleting the object is not the same as the
	condition used to create it -- so it could possibly result in a memory
	leak in some situations.  This patch fixes the problem by introducing
	a new unique_ptr that holds this object when necessary.

	Use auto_obstack in objfile
	This changes objfile to use an auto_obstack.  This helps prevent
	use-after-free bugs, because it ensures that anything allocated on the
	objfile obstack will live past the point at which the registry object

	Use gdb_bfd_ref_ptr in objfile
	This changes struct objfile to use a gdb_bfd_ref_ptr.  In addition to
	removing some manual memory management, this fixes a use-after-free
	that was introduced by the registry rewrite series.  The issue there
	was that, in some cases, registry shutdown could refer to memory that
	had already been freed.  This help fix the bug by delaying the
	destruction of the BFD reference (and thus the per-bfd object) until
	after the registry has been shut down.

	gdb: Fix regression in varobj recreation
	Commit bc20e562ec0 "Fix use after free in varobj" introduced a
	regression.  This commit makes sure that the varobj object does not
	keeps stale references to object being freed when we unload an objfile.
	This includes the "valid_block" field which is reset to nullptr if the
	pointed to block is tied to an objfile being freed.

	However, at some point varobj_invalidate_iter might try to recreate
	varobjs tracking either floating or globals.  Varobj tracking globals
	are identified as having the "valid_block" field set nullptr, but as
	bc20e562ec0 might clear this field, we have lost the ability to
	distinguish between varobj referring to globals and non globals.

	Fix this by introducing a "global" flag which tracks if a given varobj
	was initially created as tracking a global.

	Re: PE objdump -x
	All of these buffer overrun tests are better written as a comparison
	against size remaining, due to ISO C 9899 standard 6.5.2 para 8
	regarding adding a constant to a pointer:

	"If both the pointer operand and the result point to elements of the
	same array object, or one past the last element of the array object,
	the evaluation shall not produce an overflow; otherwise, the behavior
	is undefined."

	So "ex_dta + 4" might be undefined behaviour, if you interpret "the
	array object" in this case to be the malloc'd section contents!

	Even when there are no symbols (e.g. all relocations being against

	the relocations. The respective checks in assign_section_numbers() and

	ld: aarch64: Adjust TLS relaxation condition
	In aarch64_tls_transition_without_check and elfNN_aarch64_tls_relax we
	choose whether to perform a relaxation to an IE access model or an LE
	access model based on whether the symbol itself is marked as local (i.e.
	`h == NULL`).

	This is problematic in two ways.  The first is that sometimes a global
	dynamic access can be relaxed to an initial exec access when creating a
	shared library, and if that happens on a local symbol then we currently
	relax it to a local exec access instead.  This usually does not happen
	since we only relax an access if aarch64_can_relax_tls returns true and
	aarch64_can_relax_tls does not have the same problem.  However, it can
	happen when we have seen both an IE and GD access on the same symbol.
	This case is exercised in the newly added testcase tls-relax-gd-ie-2.

	The second problem is that deciding based on whether the symbol is local
	misses the case when the symbol is global but is still non-interposable
	and known to be located in the executable.  This happens on all global
	symbols in executables.
	This case is exercised in the newly added testcase tls-relax-ie-le-4.

	Here we adjust the condition we base our relaxation on so that we relax
	to local-exec if we are creating an executable and the relevant symbol
	we're accessing is stored inside that executable.

	-- Updating tests for new relaxation criteria

	Many of the tests added to check our relaxation to IE were implemented
	by taking advantage of the fact that we did not relax a global symbol
	defined in an executable.

	Since a global symbol defined in an executable is still not
	interposable, we know that a TLS version of such a symbol will be in the
	main TLS block.  This means that we can perform a stronger relaxation on
	such symbols and relax their accesses to a local-exec access.

	Hence we have to update all tests that relied on the older suboptimal
	decision making.

	The two cases when we still would want to relax a general dynamic access
	to an initial exec one are:
	1) When in a shared library and accessing a symbol which we have already
	   seen accessed with an initial exec access sequence.
	2) When in an executable and accessing a symbol defined in a shared
	   library.

	Both of these require shared library support, which means that these
	tests are now only available on targets with that.

	I have chosen to switch the existing testcases from a plain executable
	to one dynamically linked to a shared object as that doesn't require
	changing the testcases quite so much (just requires accessing a
	different variable rather than requiring adding another code sequence).

	The tls-relax-all testcase was an outlier to the above approach, since
	it included a general dynamic access to both a local and global symbol
	and inspected for the difference accordingly.

	ld: aarch64: Update test linker scripts relocs.ld and relocs-ilp32.ld

	RWX segment and avoid the corresponding warning.

	We get this warning when testing aarch64-none-elf with -mcmodel=tiny.
	N.b. this changes quite a few testcases from fail to pass.

	arm: Use DWARF numbering convention for pseudo-register representation
	This patch modifies the internal `struct reg_entry' numbering of DWARF
	pseudo-registers to match values assigned in DWARF standards (see "4.1
	DWARF register names" in [1])so ra_auth_code goes from 12 to 143 and
	amends the unwinder .save directive-processing code to correctly handle
	mixed register-type save directives.

	The mechanism for splitting the register list is also re-written to
	comply with register ordering on push statements, being that registers
	are stored on the stack in numerical order, with the lowest numbered
	register at the lowest address [2].

	Consequently, the parsing of the hypothetical directive

	        .save{r4-r7, r10, ra_auth_core, lr}

	has been changed such as rather than producing

	        .save{r4-r7, r10}
	        .save{ra_auth_code}
	        .save{lr}

	as was the case with previous implementation, now produces:

	[gdb/symtab] Fix .debug_aranges duplicate offset warning
	The function read_addrmap_from_aranges contains code to issue a warning:

	      if (!insertpair.second)
	       {
	         warning (_("Section .debug_aranges in %s has duplicate "
	                    "debug_info_offset %s, ignoring .debug_aranges."),

	         return false;
	       }
	...
	but the warning is in fact activated when all_comp_units has duplicate
	entries, which is very misleading.

	Fix this by:
	- adding a test-case that should trigger the warning,
	- replacing the current implementation of the warning with an
	  assert that all_comp_units should not contain duplicates, and
	- properly re-implementing the warning, such that it is triggered

	      /* Note: Interprets ULLONG_MAX as -1.  */
	      yylval.typed_val.type = type_long_long (par_state);
	...

	With aarch64, we have instead:
	...
	(gdb) p int_bits
	$1 = 32
	(gdb) p long_bits
	$2 = 64
	(gdb) p long_long_bits
	$3 = 64
	...
	and so in processInt we hit the fits-in-unsigned-long case where we use
	as type unsigned long:
	...
	      yylval.typed_val.type
	        = builtin_type (par_state->gdbarch ())->builtin_unsigned_long;
	...

	It's not clear why for ada we're using long long for the
	fits-in-unsigned-long-long case.

	Fix this by using unsigned long long for the fits-in-unsigned-long-long case,
	meaning the new reference output is 18446744073709551615 instead of -1.

	Tested on x86_64-linux.

	gdb/testsuite: add macros test for source files compiled in various ways
	Using different ways of passing source file paths to compilers results n
	different file and directory paths in the line header.  For example:

	  - gcc foo.c
	  - gcc ./foo.c
	  - gcc ../cwd/foo.c
	  - gcc $PWD/foo.c

	Because of this, GDB sometimes failed to look up macros.  The previous
	patch fixed that as much as possible.  This patch adds the corresponding
	tests.

	Add both a DWARF assembler-based test and a regular test.  The DWARF
	assembled-based one tests some hard-coded debug info based on what I
	have observed some specific versions of gcc and clang generate.  We want
	to make sure that GDB keeps handling all these cases correctly, even if
	it's not always clear whether they are really valid DWARF.  Also, they
	will be tested no matter what the current target compiler is for a given
	test run.

	The regular test is compiled using the target compiler, so it may help
	find bugs when testing against some other toolchains than what was used
	to generate the DWARF assembler-based test.

	For the DWARF assembler-based test, add to testsuite/lib/dwarf.exp the
	necessary code to generate a DWARF5 .debug_macro section.  The design of
	the new procs is based on what was done for rnglists and loclists.

	To test against a specific compiler one can use this command, for
	example:

	    $ make check TESTS="gdb.base/macro-source-path.exp" RUNTESTFLAGS="CC_FOR_TARGET=clang --target_board unix/gdb:debug_flags=-gdwarf-5"

	gdb: remove code to prepend comp dir in buildsym_compunit::start_subfile
	The bit of code removed by this patch was introduced to fix the same
	kind of problem that the previous patch fixes.  That is, to try to match
	existing subfiles when different name forms are used to refer to a same
	file.

	The thread for the patch that introduced this code is:

	  https://pi.simark.ca/gdb-patches/45F8CBDF.9090501@hq.tensilica.com/

	The important bits are that the compiler produced a compilation unit
	with:

	    DW_AT_name : test.c
	    DW_AT_comp_dir : /home/maxim/W/BadgerPass/PR_14999

	and DWARF v2 line table with:

	    The Directory Table:
	    /home/maxim/W/BadgerPass/PR_14999

	    The File Name Table:
	    Entry Dir Time Size Name
	    1 1 1173897037 152 test.c

	Because the main symtab was created with only DW_AT_name, it was named
	"test.c".  And because the path built from the line header contained the
	"directory" part, it was "/home/maxim/W/BadgerPass/PR_14999/test.c".
	Because of this mismatch, thing didn't work, so they added this code to
	prepend the compilation directory to the existing subfile names, so that
	this specific case would work.

	With the changes done earlier in this series, where subfiles are
	identified using the "most complete path possible", this case would be
	handled.  The main subfile's would be
	"/home/maxim/W/BadgerPass/PR_14999/test.c" from the start
	(DW_AT_comp_dir + DW_AT_name).  It's not so different from some DWARF 5
	cases actually, which make the compilation directory explicit in the
	line table header.

	I therefore think that this code is no longer needed.  It does feel like
	a quick hack to make one specific case work, and we have a more general
	solution now.  Also, this code was introduced to work around a problem
	in the DWARF debug info or the DWARF debug info reader.  In general, I
	think it's preferable for these hacks to be located in the specific
	debug info reader code, rather than in the common code.

	Even though this code was added to work around a DWARF reader problem,
	it's possible that some other debug info reader has started taking
	advantage of this code in the mean time.  It's very difficult to
	know or verify, but I think the likelyhood is quite small, so I'm
	proposing to get rid of it to simplify things a little bit.

	gdb: add "id" fields to identify symtabs and subfiles
	Printing macros defined in the main source file doesn't work reliably
	using various toolchains, especially when DWARF 5 is used.  For example,
	using the binaries produced by either of these commands:

	    $ gcc --version
	    gcc (GCC) 11.2.0
	    $ ld --version
	    GNU ld (GNU Binutils) 2.38
	    $ gcc test.c -g3 -gdwarf-5

	    $ clang --version
	    clang version 13.0.1
	    $ clang test.c -gdwarf-5 -fdebug-macro

	I get:

	    $ ./gdb -nx -q --data-directory=data-directory a.out
	    (gdb) start
	    Temporary breakpoint 1 at 0x111d: file test.c, line 6.
	    Starting program: /home/simark/build/binutils-gdb-one-target/gdb/a.out

	    Temporary breakpoint 1, main () at test.c:6
	    6         return ZERO;
	    (gdb) p ZERO
	    No symbol "ZERO" in current context.

	When starting to investigate this (taking the gcc-compiled binary as an
	example), we see that GDB fails to look up the appropriate macro scope
	when evaluating the expression.  While stopped in
	macro_lookup_inclusion:

	    (top-gdb) p name
	    $1 = 0x62100011a980 "test.c"
	    (top-gdb) p source.filename
	    $2 = 0x62100011a9a0 "/home/simark/build/binutils-gdb-one-target/gdb/test.c"

	`source` is the macro_source_file that we would expect GDB to find.
	`name` comes from the symtab::filename field of the symtab we are
	stopped in.  GDB doesn't find the appropriate macro_source_file because
	the name of the macro_source_file doesn't match exactly the name of the
	symtab.

	The name of the main symtab comes from the compilation unit's
	DW_AT_name, passed to the buildsym_compunit's constructor:

	  https://gitlab.com/gnutools/binutils-gdb/-/blob/4815d6125ec580cc02a1094d61b8c9d1cc83c0a1/gdb/dwarf2/read.c#L10627-10630

	The contents of DW_AT_name, in this case, is "test.c".  It is typically
	(what I witnessed all compilers do) the same string that was passed to
	the compiler on the command-line.

	The name of the macro_source_file comes from the line number program
	header's file table, from the call to the line_header::file_file_name
	method:

	  https://gitlab.com/gnutools/binutils-gdb/-/blob/4815d6125ec580cc02a1094d61b8c9d1cc83c0a1/gdb/dwarf2/macro.c#L54-65

	line_header::file_file_name prepends the directory path that the file
	entry refers to, in the file table (if the file name is not already
	absolute).  In this case, the file name is "test.c", appended to the
	directory "/home/simark/build/binutils-gdb-one-target/gdb".

	Because the symtab's name is not created the same way as the
	macro_source_file's name is created, we get this mismatch.  GDB fails to
	find the appropriate macro scope for the symtab, and we can't print
	macros when stopped in that symtab.

	To make this work, we must ensure that paths produced in these two ways
	end up identical.  This can be tricky because of the different ways a
	path can be passed to the compiler by the user.

	Another thing to consider is that while the main symtab's name (or
	subfile, before it becomes a symtab) is created using DW_AT_name, the
	main symtab is also referred to using its entry in the line table
	header's file table, when processing the line table.  We must therefore
	ensure that the same name is produced in both cases, so that a call to
	"start_subfile" for the main subfile will correctly find the
	already-created subfile, created by buildsym_compunit's constructor.  If
	we fail to do that, things still often work, because of a fallback: the
	watch_main_source_file_lossage method.  This method determines that if
	the main subfile has no symbols but there exists another subfile with
	the same basename (e.g. "test.c") that does have symbols, it's probably
	because there was some filename mismatch.  So it replaces the main
	subfile with that other subfile.  I think that heuristic is useful as a
	last effort to work around any bug or bad debug info, but I don't think
	we should design things such as to rely on it.  It's a heuristic, it can
	get things wrong.  So in my search for a fix, it is important that given
	some good debug info, we don't end up relying on that for things to
	work.

	A first attempt at fixing this was to try to prepend the compilation
	directory here or not prepend it there.  In practice, because of all the
	possible combinations of debug info the compilers produce, it was not
	possible to get something that would produce reliable, consistent paths.

	Another attempt at fixing this was to make both macro_source_file
	objects and symtab objects use the most complete form of path possible.
	That means to prepend directories at least until we get an absolute
	path.  In theory, we should end up with the same path in all cases.
	This generally worked, but because it changed the symtab names, it
	resulted in user-visible changes (for example, paths to source files in
	Breakpoint hit messages becoming always absolute).  I didn't find this
	very good, first because there is a "set filename-display" setting that
	lets the user control how they want the paths to be displayed, and that
	would suddenly make this setting completely ineffective (although even
	today, it is a bit dependent on the debug info).  Second, it would
	require a good amount of testsuite tweaks to make tests accept these
	suddenly absolute paths.

	This new patch is a slight variation of that: it adds a new field called
	"filename_for_id" in struct symtab and struct subfile, next to the
	existing filename field. The goal is to separate the internal ids used
	for finding objects from the names used for presentation.  This field is
	used for identifying subfiles, symtabs and macro_source_files
	internally.  For DWARF symtabs, this new field is meant to contain the
	"most complete possible" path, as discussed above.  So for a given file,
	it must always be in the same form, everywhere.  The existing
	symtab::filename field remains the one used for printing to the user, so
	there shouldn't be any change in how paths are printed.

	Changes in the core symtab files are:

	 - Add "name_for_id" and "filename_for_id" fields to "struct subfile"
	   and "struct symtab", next to existing "name" and "filename" fields.
	 - Make buildsym_compunit::buildsym_compunit and
	   buildsym_compunit::start_subfile accept a "name_for_id" parameter
	   next to the existing "name" ones.
	 - Make buildsym_compunit::start_subfile use "name_for_id" for looking
	   up existing subfiles.  This is the key thing for making calls
	   to start_subfile for the main source file look up the existing
	   subfile successfully, and avoid relying on
	   watch_main_source_file_lossage.
	 - Make sal_macro_scope pass "filename_for_id", rather than "filename",
	   to macro_lookup_inclusion.  This is the key thing to making the
	   lookup work and macro printing work.

	Changes in the DWARF files are:

	 - Make line_header::file_file_name return the "most complete possible"
	   name.  The only pre-existing user of this method is the macro code,
	   to give the macro_source_file objects their name.  And we now want
	   them to have this "most complete possible" name, which will match the
	   corresponding symtab's "filename_for_id".
	 - Make dwarf2_cu::start_compunit_symtab pass the "most complete
	   possible" name for the main symtab's "filename_for_id".  In this
	   context, where the info comes from the compilation unit's DW_AT_name
	   / DW_AT_comp_dir, it means prepending DW_AT_comp_dir to DW_AT_name if
	   DW_AT_name is not already absolute.
	 - Change dwarf2_start_subfile to build a name_for_id for the subfile
	   being started.  The simplest way is to re-use
	   line_header::file_file_name, since the callers always have a
	   file_entry handy.  This ensures that it will get the exact same path
	   representation as the macro code does, for the same file (since it
	   also uses line_header::file_file_name).
	 - Update calls to allocate_symtab to pass the "name_for_id" from the
	   subfile.

	Tests exercising all this are added by the following patch.

	Of all the cases I tried, the only one I found that ends up relying on
	watch_main_source_file_lossage is the following one:

	    $ clang --version
	    clang version 13.0.1
	    Target: x86_64-pc-linux-gnu
	    Thread model: posix
	    InstalledDir: /usr/bin
	    $ clang  ./test.c -g3 -O0 -gdwarf-4
	    $ ./gdb -nx --data-directory=data-directory -q -readnow -iex "set debug symtab-create 1"  a.out
	    ...
	    [symtab-create] start_subfile: name = test.c, name_for_id = /home/simark/build/binutils-gdb-one-target/gdb/test.c
	    [symtab-create] start_subfile: name = ./test.c, name_for_id = /home/simark/build/binutils-gdb-one-target/gdb/./test.c
	    [symtab-create] start_subfile: name = ./test.c, name_for_id = /home/simark/build/binutils-gdb-one-target/gdb/./test.c
	    [symtab-create] start_subfile: found existing symtab with name_for_id /home/simark/build/binutils-gdb-one-target/gdb/./test.c (/home/simark/build/binutils-gdb-one-target/gdb/./test.c)
	    [symtab-create] watch_main_source_file_lossage: using subfile ./test.c as the main subfile

	As we can see, there are two forms used for "test.c", one with a "." and
	one without.  This comes from the fact that the compilation unit DIE
	contains:

	    DW_AT_name ("test.c")
	    DW_AT_comp_dir ("/home/simark/build/binutils-gdb-one-target/gdb")

	without a ".", and the line table for that file contains:

	    include_directories[  1] = "."
	    file_names[  1]:
	               name: "test.c"
	          dir_index: 1

	When assembling the filename from that entry, we get a ".".

	It is a bit unexpected that the main filename resulting from the line
	table header does not match exactly the name in the compilation unit.
	For instance, gcc uses "./test.c" for the DW_AT_name, which gives
	identical paths in the compilation unit and in the line table header.

	Similarly, with DWARF 5:

	    $ clang  ./test.c -g3 -O0 -gdwarf-5

	clang create two entries that refer to the same file but are of in a different
	form.

	    include_directories[  0] = "/home/simark/build/binutils-gdb-one-target/gdb"
	    include_directories[  1] = "."
	    file_names[  0]:
	               name: "test.c"
	          dir_index: 0
	    file_names[  1]:
	               name: "test.c"
	          dir_index: 1

	The first file name produces a path without a "." while the second does.
	This is not caught by watch_main_source_file_lossage, because of
	dwarf_decode_lines that creates a symtab for each file entry in the line
	table.  It therefore appears as "non-empty" to
	watch_main_source_file_lossage.  This results in two symtabs:

	    (gdb) maintenance info symtabs
	    { objfile /home/simark/build/binutils-gdb-one-target/gdb/a.out ((struct objfile *) 0x613000005d00)
	      { ((struct compunit_symtab *) 0x62100011aca0)
	        debugformat DWARF 5
	        producer clang version 13.0.1
	        name test.c
	        dirname /home/simark/build/binutils-gdb-one-target/gdb
	        blockvector ((struct blockvector *) 0x621000129ec0)
	        user ((struct compunit_symtab *) (null))
	            { symtab test.c ((struct symtab *) 0x62100011ad20)
	              fullname (null)
	              linetable ((struct linetable *) 0x0)
	            }
	            { symtab ./test.c ((struct symtab *) 0x62100011ad60)
	              fullname (null)
	              linetable ((struct linetable *) 0x621000129ef0)
	            }
	      }
	    }

	I am not sure what is the consequence of this, but this is also what
	happens before my patch, so I think its acceptable to leave it as-is.

	To handle these two cases nicely, I think we will need a function that
	removes the unnecessary "." from path names, something that can be done
	later.

	Finally, I made a change in find_file_and_directory is necessary to
	avoid breaking test

	    gdb.dwarf2/dw2-compdir-oldgcc.exp: info source gcc42

	Without that change, we would get:

	    (gdb) info source
	    Current source file is /dir/d/dw2-compdir-oldgcc42.S
	    Compilation directory is /dir/d

	whereas the expected result is:

	    (gdb) info source
	    Current source file is dw2-compdir-oldgcc42.S
	    Compilation directory is /dir/d

	This test was added here:

	  https://sourceware.org/pipermail/gdb-patches/2012-November/098144.html

	Long story short, GCC <= 4.2 apparently had a bug where it would
	generate a DW_AT_name with a full path ("/dir/d/dw2-compdir-oldgcc42.S")
	and no DW_AT_comp_dir.  The line table has one entry with filename
	"dw2-compdir-oldgcc42.S", which refers to directory 0.  Directory 0
	normally refers to the compilation unit's comp dir, but it is
	non-existent in this case.

	This caused some symtab lookup problems, and to work around them, some
	workaround was added, which today reads as:

	    if (res.get_comp_dir () == nullptr
	        && producer_is_gcc_lt_4_3 (cu)
	        && res.get_name () != nullptr
	        && IS_ABSOLUTE_PATH (res.get_name ()))
	      res.set_comp_dir (ldirname (res.get_name ()));

	Source: https://gitlab.com/gnutools/binutils-gdb/-/blob/6577f365ebdee7dda71cb996efa29d3714cbccd0/gdb/dwarf2/read.c#L9428-9432

	It extracts an artificial DW_AT_comp_dir from DW_AT_name, if there is no
	DW_AT_comp_dir and DW_AT_name is absolute.

	Prior to my patch, a subfile would get created with filename
	"/dir/d/dw2-compdir-oldgcc42.S", from DW_AT_name, and another would get
	created with filename "dw2-compdir-oldgcc42.S" from the line table's
	file table.  Then watch_main_source_file_lossage would kick in and merge
	them, keeping only the "dw2-compdir-oldgcc42.S" one:

	    [symtab-create] start_subfile: name = /dir/d/dw2-compdir-oldgcc42.S
	    [symtab-create] start_subfile: name = dw2-compdir-oldgcc42.S
	    [symtab-create] start_subfile: name = dw2-compdir-oldgcc42.S
	    [symtab-create] start_subfile: found existing symtab with name dw2-compdir-oldgcc42.S (dw2-compdir-oldgcc42.S)
	    [symtab-create] watch_main_source_file_lossage: using subfile dw2-compdir-oldgcc42.S as the main subfile

	And so "info source" would show "dw2-compdir-oldgcc42.S" as the
	filename.

	With my patch applied, but without the change in
	find_file_and_directory, both DW_AT_name and the line table would try to
	start a subfile with the same filename_for_id, and there was no need for
	watch_main_source_file_lossage - which is what we want:

	[symtab-create] start_subfile: name = /dir/d/dw2-compdir-oldgcc42.S, name_for_id = /dir/d/dw2-compdir-oldgcc42.S
	[symtab-create] start_subfile: name = dw2-compdir-oldgcc42.S, name_for_id = /dir/d/dw2-compdir-oldgcc42.S
	[symtab-create] start_subfile: found existing symtab with name_for_id /dir/d/dw2-compdir-oldgcc42.S (/dir/d/dw2-compdir-oldgcc42.S)
	[symtab-create] start_subfile: name = dw2-compdir-oldgcc42.S, name_for_id = /dir/d/dw2-compdir-oldgcc42.S
	[symtab-create] start_subfile: found existing symtab with name_for_id /dir/d/dw2-compdir-oldgcc42.S (/dir/d/dw2-compdir-oldgcc42.S)

	But since the one with name == "/dir/d/dw2-compdir-oldgcc42.S", coming
	from DW_AT_name, gets created first, it wins, and the symtab ends up
	with "/dir/d/dw2-compdir-oldgcc42.S" as the name, "info source" shows
	"/dir/d/dw2-compdir-oldgcc42.S" and the test breaks.

	This is not wrong per-se, after all DW_AT_name is
	"/dir/d/dw2-compdir-oldgcc42.S", so it wouldn't be wrong to report the
	current source file as "/dir/d/dw2-compdir-oldgcc42.S".  If you compile
	a file passing "/an/absolute/path.c", DW_AT_name typically contains (at
	least with GCC) "/an/absolute/path.c" and GDB tells you that the source
	file is "/an/absolute/path.c".  But we can also keep the existing
	behavior fairly easily with a little change in find_file_and_directory.
	When extracting an artificial DW_AT_comp_dir from DW_AT_name, we now
	modify the name to just keep the file part.  The result is coherent with
	what compilers do when you compile a file by just passing its filename
	("gcc path.c -g"):

	      DW_AT_name        ("path.c")
	      DW_AT_comp_dir    ("/home/simark/build/binutils-gdb-one-target/gdb")

	With this change, filename_for_id is still the full name,
	"/dir/d/dw2-compdir-oldgcc42.S", but the filename of the subfile /
	symtab (what ends up shown by "info source") is just
	"dw2-compdir-oldgcc42.S", and that makes the test happy.

	gdb/dwarf: pass a file_entry to line_header::file_file_name
	In the following patch, there will be some callers of file_file_name
	that will already have access to the file_entry object for which they
	want the file name.  It would be inefficient to have them pass an index,
	only for line_header::file_file_name to re-lookup the same file_entry
	object.  Change line_header::file_file_name to accept a file_entry
	object reference, instead of an index to look up.

	I think this change makes sense in any case.  Callers that have an index
	can first obtain a file_entry using line_header::file_name_at or
	line_header::file_names.

	When passing a file_entry object, we can assume that the file_entry's
	index is valid, unlike when passing an index.  So, push the special case
	about an invalid index to the sole current caller of file_file_name,
	macro_start_file.  I think that error belongs there anyway, since it
	specifically talks about "bad file number in macro information".

	This requires recording the file index in the file_entry structure, so
	add that.

	gdb/dwarf: pass compilation directory to line header
	The following patch changes line_header::file_file_name to prepend the
	compilation directory to the file name, if needed.  For that, the line
	header needs to know about the compilation directory.  Prepare for that
	by adding a constructor that takes it as a parameter, and passing the
	value down everywhere needed.  Add a second constructor for the special
	case of building a line_header for doing a hash table lookup, since that
	case doesn't require a compilation directory value.

	libopcodes/aarch64: add support for disassembler styling
	This commit enables disassembler styling for AArch64.  After this
	commit it is possible to have objdump style AArch64 disassembler
	output (using --disassembler-color option).  Once the required GDB
	patches are merged, GDB will also style the disassembler output.

	The changes to support styling are mostly split between two files
	opcodes/aarch64-dis.c and opcodes/aarch64-opc.c.

	The entry point for the AArch64 disassembler can be found in
	aarch64-dis.c, this file handles printing the instruction mnemonics,
	and assembler directives (e.g. '.byte', '.word', etc).  Some operands,
	mostly relating to assembler directives are also printed from this
	file.  This commit changes all of this to pass through suitable
	styling information.

	However, for most "normal" instructions, the instruction operands are
	printed using a two step process.  From aarch64-dis.c, in the
	print_operands function, the function aarch64_print_operand is called,
	this function is in aarch64-opc.c, and converts an instruction operand
	into a string.  Then, back in print_operands (aarch64-dis.c), the
	operand string is printed.

	Unfortunately, the string returned by aarch64_print_operand can be
	quite complex, it will include syntax elements, like '[' and ']', in
	addition to register names and immediate values.  In some cases, a
	single operand will expand into what will appear (to the user) as
	multiple operands separated with a ','.

	This makes the task of styling more complex, all these different
	components need to by styled differently, so we need to get the
	styling information out of aarch64_print_operand in some way.

	The solution that I propose here is similar to the solution that I
	used for the i386 disassembler.

	Currently, aarch64_print_operand uses snprintf to write the operand
	text into a buffer provided by the caller.

	What I propose is that we pass an extra argument to the
	aarch64_print_operand function, this argument will be a structure, the
	structure contains a callback function and some state.

	When aarch64_print_operand needs to format part of its output this can
	be done by using the callback function within the new structure, this
	callback returns a string with special embedded markers that indicate
	which mode should be used for each piece of text.  Back in
	aarch64-dis.c we can spot these special style markers and use this to
	split the disassembler output up and apply the correct style to each
	piece.

	To make aarch64-opc.c clearer a series of new static functions have
	been added, e.g. 'style_reg', 'style_imm', etc.  Each of these
	functions formats a piece of text in a different style, 'register' and
	'immediate' in this case.

	Here's an example taken from aarch64-opc.c of the new functions in
	use:

	    snprintf (buf, size, "[%s, %s]!",
	              style_reg (styler, base),
	              style_imm (styler, "#%d", opnd->addr.offset.imm));

	The aarch64_print_operand function is also called from the assembler
	to aid in printing diagnostic messages.  Right now I have no plans to
	add styling to the assembler output, and so, the callback function
	used in the assembler ignores the styling information and just returns
	an plain string.

	I've used the source files in gas/testsuite/gas/aarch64/ for testing,
	and have manually gone through and checked that the styling looks
	reasonable, however, I'm not an AArch64 expert, so it is possible that
	the odd piece is styled incorrectly.  Please point out any mistakes
	I've made.

	With objdump disassembler color turned off, there should be no change
	in the output after this commit.

	x86: drop stray NoRex64 from KeyLocker insns
	It's entirely unclear why some of the KeyLocker insns had NoRex64 on
	them - there's nothing here which could cause emission of REX.W (except
	of course a user-specified "rex.w", which we ought to honor anyway).

2022-07-29  Jan Beulich  <jbeulich@suse.com>

	Arm64: re-work PR gas/27217 fix
	The original approach has resulted in anomalies when . is involved in an
	operand of one of the affected insns. We cannot leave . unresolved, or
	else it'll be resolved at the end of assembly, then pointing to the
	address of a section rather than at the insn of interest. Undo part of
	the original change and instead check whether a relocation cannot be
	omitted in md_apply_fix().

	By resolving the expressions again, equates (see the adjustment of the
	respective testcase) will now be evaluated, and hence relocations
	against absolute addresses be emitted. This ought to be okay as long as
	the equates aren't global (and hence can't be overridden). If a need
	for such arises, quite likely the only way to address this would be to
	invent yet another expression evaluation mode, leaving everything
	_except_ . un-evaluated.

	There's a further anomaly in how transitive equates are handled. In

		.set x, 0x12345678
		.eqv bar, x
	foo:
		adrp	x0, x
		add	x0, x0, :lo12:x

		adrp	x0, bar
		add	x0, x0, :lo12:bar

	the first two relocations are now against *ABS*:0x12345678 (as said
	above), whereas the latter two relocations would be against x. (Before
	the change here, the first two relocations are against x and the latter
	two against bar.) But this is an issue seen elsewhere as well, and would
	likely require adjustments in the target-independent parts of the
	assembler instead of trying to hack around this for every target.

	Remove some unneeded checks in Guile code
	The Guile code generally checks to see if an htab is non-null before
	destroying it.  However, the registry code already ensures this, so we
	can change these checks to asserts and simplify the code a little.

	Change registry to use less memory
	The registry code creates "registry_data" objects that hold the free
	function and the index; then the registry keys refer to this object.
	However, only the index is really useful, and now that registries have
	a private implementation, just the index can be stored and we can
	reduce the memory use of registries a little bit.  This also
	simplifies the code somewhat.

	Rewrite registry.h
	This rewrites registry.h, removing all the macros and replacing it
	with relatively ordinary template classes.  The result is less code
	than the previous setup.  It replaces large macros with a relatively
	straightforward C++ class, and now manages its own cleanup.

	The existing type-safe "key" class is replaced with the equivalent
	template class.  This approach ended up requiring relatively few
	changes to the users of the registry code in gdb -- code using the key
	system just required a small change to the key's declaration.

	All existing users of the old C-like API are now converted to use the
	type-safe API.  This mostly involved changing explicit deletion
	functions to be an operator() in a deleter class.

	The old "save/free" two-phase process is removed, and replaced with a
	single "free" phase.  No existing code used both phases.

	The old "free" callbacks took a parameter for the enclosing container
	object.  However, this wasn't truly needed and is removed here as
	well.

	Change allocation of type-copying hash table
	When an objfile is destroyed, types that are still in use and
	allocated on that objfile are copied.  A temporary hash map is created
	during this process, and it is allocated on the destroyed objfile's
	obstack -- which normally is fine, as that is going to be destroyed
	shortly anyway.

	However, this approach requires that the objfile be passed to registry
	destruction, and this won't be possible in the rewritten registry.
	This patch changes the copied type hash table to simply use the heap
	instead.  It also removes the 'objfile' parameter from
	copy_type_recursive, to make this all more clear.

	This patch also fixes an apparent bug in copy_type_recursive.
	Previously it was copying the dynamic property list to the dying
	objfile's obstack:

	-      = copy_dynamic_prop_list (&objfile->objfile_obstack,

	However I think this is incorrect -- that obstack is about to be
	destroyed.

	gdb/python: Add BreakpointLocation type
	PR python/18385

	v7:
	This version addresses the issues pointed out by Tom.

	Added nullchecks for Python object creations.

	Changed from using PyLong_FromLong to the gdb_py-versions.

	Re-factored some code to make it look more cohesive.

	Also added the more safe Python reference count decrement PY_XDECREF,
	even though the BreakpointLocation type is never instantiated by the
	user (explicitly documented in the docs) decrementing < 0 is made
	impossible with the safe call.

	Tom pointed out that using the policy class explicitly to decrement a
	reference counted object was not the way to go, so this has instead been
	wrapped in a ref_ptr that handles that for us in blocpy_dealloc.

	Moved macro from py-internal to py-breakpoint.c.

	Renamed section at the bottom of commit message "Patch Description".

	v6:
	This version addresses the points Pedro gave in review to this patch.

	Added the attributes `function`, `fullname` and `thread_groups`
	as per request by Pedro with the argument that it more resembles the
	output of the MI-command "-break-list".  Added documentation for these attributes.

	Cleaned up left overs from copy+paste in test suite, removed hard coding
	of line numbers where possible.

	Refactored some code to use more c++-y style range for loops
	wrt to breakpoint locations.

	Changed terminology, naming was very inconsistent. Used a variety of "parent",
	"owner". Now "owner" is the only term used, and the field in the
	gdb_breakpoint_location_object now also called "owner".

	v5:

	Changes in response to review by Tom Tromey:
	- Replaced manual INCREF/DECREF calls with
	  gdbpy_ref ptrs in places where possible.
	- Fixed non-gdb style conforming formatting
	- Get parent of bploc increases ref count of parent.
	- moved bploc Python definition to py-breakpoint.c

	The INCREF of self in bppy_get_locations is due
	to the individual locations holding a reference to
	it's owner. This is decremented at de-alloc time.

	The reason why this needs to be here is, if the user writes
	for instance;

	py loc = gdb.breakpoints()[X].locations[Y]

	The breakpoint owner object is immediately going
	out of scope (GC'd/dealloced), and the location
	object requires it to be alive for as long as it is alive.

	Thanks for your review, Tom!

	v4:
	Fixed remaining doc issues as per request
	by Eli.

	v3:
	Rewritten commit message, shortened + reworded,
	added tests.

	Patch Description

	Currently, the Python API lacks the ability to
	query breakpoints for their installed locations,
	and subsequently, can't query any information about them, or
	enable/disable individual locations.

	This patch solves this by adding Python type gdb.BreakpointLocation.
	The type is never instantiated by the user of the Python API directly,
	but is produced by the gdb.Breakpoint.locations attribute returning
	a list of gdb.BreakpointLocation.

	gdb.Breakpoint.locations:
	The attribute for retrieving the currently installed breakpoint
	locations for gdb.Breakpoint. Matches behavior of
	the "info breakpoints" command in that it only
	returns the last known or currently inserted breakpoint locations.

	BreakpointLocation contains 7 attributes

	6 read-only attributes:
	owner: location owner's Python companion object
	source: file path and line number tuple: (string, long) / None
	address: installed address of the location
	function: function name where location was set
	fullname: fullname where location was set
	thread_groups: thread groups (inferiors) where location was set.

	1 writeable attribute:
	enabled: get/set enable/disable this location (bool)

	Access/calls to these, can all throw Python exceptions (documented in
	the online documentation), and that's due to the nature
	of how breakpoint locations can be invalidated
	"behind the scenes", either by them being removed
	from the original breakpoint or changed,
	like for instance when a new symbol file is loaded, at
	which point all breakpoint locations are re-created by GDB.
	Therefore this patch has chosen to be non-intrusive:
	it's up to the Python user to re-request the locations if
	they become invalid.

	Also there's event handlers that handle new object files etc, if a Python
	user is storing breakpoint locations in some larger state they've
	built up, refreshing the locations is easy and it only comes
	with runtime overhead when the Python user wants to use them.

	gdb.BreakpointLocation Python type
	struct "gdbpy_breakpoint_location_object" is found in python-internal.h

	Its definition, layout, methods and functions
	are found in the same file as gdb.Breakpoint (py-breakpoint.c)

	1 change was also made to breakpoint.h/c to make it possible
	to enable and disable a bp_location* specifically,
	without having its LOC_NUM, as this number
	also can change arbitrarily behind the scenes.

	Updated docs & news file as per request.

	Testsuite: tests the .source attribute and the disabling of
	individual locations.

	gdb/linux_nat: Write memory using ptrace if /proc/pid/mem is not writable
	Commit 05c06f318fd9a112529dfc313e6512b399a645e4 enabled GDB to access
	memory while threads are running.  It did this by accessing
	/proc/PID/task/LWP/mem.

	Unfortunately, this interface is not implemented for writing in older
	kernels (such as RHEL6).  This means that GDB is unable to insert
	breakpoints on these hosts:

	 $ ./gdb -q gdb -ex start
	 Reading symbols from gdb...
	 Temporary breakpoint 1 at 0x40fdd5: file ../../src/gdb/gdb.c, line 28.
	 Starting program: /home/rhel6/fsf/linux/gdb/gdb
	 Warning:
	 Cannot insert breakpoint 1.
	 Cannot access memory at address 0x40fdd5

	 (gdb)

	Before this patch, linux_proc_xfer_memory_partial (previously called
	linux_proc_xfer_partial) would return TARGET_XFER_EOF if the write to
	/proc/PID/mem failed. [More specifically, linux_proc_xfer_partial
	would not "bother for one word," but the effect is the essentially
	same.]

	This status was checked by linux_nat_target::xfer_partial, which would
	then fallback to using ptrace to perform the operation.

	This is the specific hunk that removed the fallback:

	-  xfer = linux_proc_xfer_partial (object, annex, readbuf, writebuf,
	-                                 offset, len, xfered_len);
	-  if (xfer != TARGET_XFER_EOF)
	-    return xfer;
	+      return linux_proc_xfer_memory_partial (readbuf, writebuf,
	+                                            offset, len, xfered_len);
	+    }

	   return inf_ptrace_target::xfer_partial (object, annex, readbuf, writebuf,
	                                          offset, len, xfered_len);

	This patch makes linux_nat_target::xfer_partial go straight to writing
	memory via ptrace if writing via /proc/pid/mem is not possible in the
	running kernel, enabling GDB to insert breakpoints on these older
	kernels.  Note that a recent patch changed the return status from
	TARGET_XFER_EOF to TARGET_XFER_E_IO.

	Tested on {unix,native-gdbserver,native-extended-gdbserver}/-m{32,64}
	on x86_64, s390x, aarch64, and ppc64le.

	gdb: rename gdbarch_tdep struct to fix g++ 4.8 build
	After the commit:

	  commit 08106042d9f5fdff60c129bf33190639f1a98b2a
	  Date:   Thu May 19 13:20:17 2022 +0100

	      gdb: move the type cast into gdbarch_tdep

	GDB would no longer build using g++ 4.8.  The issue appears to be some
	confusion caused by GDB having 'struct gdbarch_tdep', but also a
	templated function called 'gdbarch_tdep'.  Prior to the above commit
	the gdbarch_tdep function was not templated, and this compiled just
	fine.  Note that the above commit compiles just fine with later
	versions of g++, so this issue was clearly fixed at some point, though
	I've not tried to track down exactly when.

	In this commit I propose to fix the g++ 4.8 build problem by renaming
	'struct gdbarch_tdep' to 'struct gdbarch_tdep_base'.  This rename
	better represents that the struct is only ever used as a base class,
	and removes the overloading of the name, which allows GDB to build
	with g++ 4.8.

	I've also updated the comment on 'struct gdbarch_tdep_base' to fix a
	typo, and the comment on the 'gdbarch_tdep' function, to mention that
	in maintainer mode a run-time type check is performed.

	gdb/varobj: Fix varobj_invalidate_iter
	The varobj_invalidate function is meant to be called when restarting a
	process, and check at this point if some of the previously existing
	varobj can be recreated in the context of the new process.

	Two kind of varobj are subject to re-creation:  global varobj (i.e.
	varobj which reference a global variable), and floating varobj (i.e.
	varobj which are always re-evaluated in the context of whatever is
	the currently selected frame at the time of evaluation).

	However, in the re-creation process, the varobj_invalidate_iter
	recreates floating varobj as non-floating, due to an invalid parameter.
	This patches fixes this and adds an assertion to check that if a varobj
	is indeed recreated, it matches the original varobj "floating" property.

	Another issue is that if at this recreation time the expression watched
	by the floating varobj is not in scope, then the varobj is marked as
	invalid.  If later the user selects a frame where the expression becomes
	valid, the varobj remains invalid and this is wrong.  This patch also
	make sure that floating varobj are not invalidated if they cannot be
	evaluated.

	The last important thing to note is that due to the previous patch, when
	varobj_invalidate is executed (in the context of a new process), any
	global var have already been invalidated (this has been done when the
	objfile it referred to got invalidated).  As a consequence,
	varobj_invalidate tries to recreate vars which are already marked as
	invalid.  This does not entirely feels right, but I keep this behavior
	for backward compatibility.

	Tested on x86_64-linux

	gdb/varobj: Fix use after free in varobj
	Varobj object contains references to types, variables (i.e. struct
	variable) and expression.  All of those can reference data on an
	objfile's obstack.  It is possible for this objfile to be deleted (and
	the obstack to be feed), while the varobj remains valid.  Later, if the
	user uses the varobj, this will result in a use-after-free error.  With
	address sanitizer build, this leads to a plain error.  For non address
	sanitizer build we might see undefined behaviour, which manifest
	themself as assertion failures when accessing data backed by feed
	memory.

	This can be observed if we create a varobj that refers to ta symbol in a
	shared library, after either the objfile gets reloaded (using the `file`
	command) or after the shared library is unloaded (with a call to dlclose
	for example).

	This patch fixes those issues by:

	- Adding cleanup procedure to the free_objfile observable.  When
	  activated this observer clears expressions referencing the objfile
	  being freed, and removes references to blocks belonging to this
	  objfile.
	- Adding varobj support in the `preserve_values` (gdb.value.c).  This
	  ensures that before the objfile is unloaded, any type owned by the
	  objfile referenced by the varobj is replaced by an equivalent type
	  not owned by the objfile.  This process is done here instead of in the
	  free_objfile observer in order to reuse the type hash table already
	  used for similar purpose when replacing types of values kept in the
	  value history.

	This patch also makes sure to keep a reference to the expression's
	gdbarch and language_defn members when the varobj->root->exp is
	initialized.  Those structures outlive the objfile, so this is safe.
	This is done because those references might be used initialize a python
	context even after exp is invalidated.  Another approach could have been
	to initialize the python context with default gdbarch and language_defn
	(i.e. nullptr) if expr is NULL, but since we might still try to display
	the value which was obtained by evaluating exp when it was still valid,
	keeping track of the context which was used at this time seems
	reasonable.

	Tested on x86_64-Linux.

	MI: mi_runto -pending
	With the CLI testsuite's runto proc, we can pass "allow-pending" as an
	option, like:

	  runto func allow-pending

	That is currently not possible with MI's mi_runto, however.  This
	patch makes it possible, by adding a new "-pending" option to
	mi_runto.

	A pending breakpoint shows different MI attributes compared to a
	breakpoint with a location, so the regexp returned by
	mi_make_breakpoint isn't suitable.  Thus, add a new
	mi_make_breakpoint_pending proc for pending breakpoints.

	Tweak mi_runto to let it take and pass down arguments.

	set/show python dont-write-bytecode fixes
	GDB uses the environment variable PYTHONDONTWRITEBYTECODE to
	determine whether or not to write the result of byte-compiling
	python modules when the "python dont-write-bytecode" setting
	is "auto".  Simon noticed that GDB's implementation doesn't
	follow the Python documentation.

	At present, GDB only checks for the existence of this environment
	variable.  That is not sufficient though.  Regarding
	PYTHONDONTWRITEBYTECODE, this document...

	    https://docs.python.org/3/using/cmdline.html

	...says:

	    If this is set to a non-empty string, Python won't try to write
	    .pyc files on the import of source modules.

	This commit fixes GDB's handling of PYTHONDONTWRITEBYTECODE by adding
	an empty string check.

	This commit also corrects the set/show command documentation for
	"python dont-write-bytecode".  The current doc was just a copy
	of that for set/show python ignore-environment.

	During his review of an earlier version of this patch, Eli Zaretskii
	asked that the help text that I proposed for "set/show python
	dont-write-bytecode" be expanded.  I've done that in addition to
	clarifying the documentation of this option in the GDB manual.

	gdb/python: fix invalid use disassemble_info::stream

	      gdb: have gdb_disassemble_info carry 'this' in its stream pointer

	The disassemble_info::stream field will no longer be a ui_file*.  That
	commit failed to update one location in py-disasm.c though.

	While running some tests using the Python disassembler API, I
	triggered a call to gdbpy_disassembler::print_address_func, and, as I
	had compiled GDB with the undefined behaviour sanitizer, GDB crashed
	as the code currently (incorrectly) casts the stream field to be a
	ui_file*.

	In this commit I fix this error.

	In order to test this case I had to tweak the existing test case a
	little.  I also spotted some debug printf statements in py-disasm.py,
	which I have removed.

	gdb: fix use of uninitialised gdb_printing_disassembler::m_in_comment
	Simon pointed out that gdb_printing_disassembler::m_in_comment can be
	used uninitialised by the Python disassembler API code.  This issue
	was spotted when GDB was built with the undefined behaviour sanitizer,
	and causes the gdb.python/py-disasm.exp test to fail like this:

	  (gdb) PASS: gdb.python/py-disasm.exp: global_disassembler=GlobalPreInfoDisassembler: python add_global_disassembler(GlobalPreInfoDisassembler)

	  /home/user/src/binutils-gdb/gdb/disasm.h:144:12: runtime error: load of value 118, which is not a valid value for type 'bool'

	The problem is that in disasmpy_builtin_disassemble we create a new
	instance of gdbpy_disassembler, which is a sub-class of
	gdb_printing_disassembler, however, the m_in_comment field is never
	initialised.

	This commit fixes the issue by providing a default initialisation
	value for m_in_comment in disasm.h.  As we only ever disassemble a
	single instruction in disasmpy_builtin_disassemble then we don't need
	to worry about reseting m_in_comment back to false after the single
	instruction has been disassembled.

	With this commit the above issue is resolved and
	gdb.python/py-disasm.exp now passes.

	The issue is that mingw gcc defaults to "-mms-bitfields", which
	affects how bitfields are laid out.  We can however tell GCC that we
	want the regular GCC layout instead using attribute gcc_struct.

	binutils-gdb/git: highlight whitespace errors in source files
	For a long time I've had this in my ~/.gitconfig:

	  [core]
	          whitespace = space-before-tab,indent-with-non-tab,trailing-space

	which causes git to show me if I muck up and use spaces instead of
	tabs, or leave in trailing whitespace.  I find this really useful.

	I recently proposed adding something like this to the .gitattributes
	files for the GDB sub-directories (gdb, gdbsupport, and gdbserver)[1],
	however, the question was asked - couldn't this be done at the top
	level?

	So, in this commit, I propose to update the top-level .gitattributes
	file, after this commit, any git diff on a C, C++, Expect, or TCL
	source file, will highlight the following whitespace errors:

	  (a) Use a space before a tab at the start of a line,

	  (b) Use of spaces where a tab could be used at the start of a line,
	  and

	  (c) Any trailing whitespace.

	Errors are only highlighted in the diff on new or modified lines, so
	you don't get spammed for errors on context lines that you haven't
	modified.

	The only downside I see to adding this at the top level is if there
	are any sub-directories that don't follow the tabs/spaces indentation
	rules very well already, in those directories you'll end up hitting
	issues any time you edit a line.  For GDB we're usually pretty good,
	so having this highlighting isn't an issue.

	gdb/arm: Sync sp with other *sp registers
	For Arm Cortex-M33 with security extensions, there are 4 different
	stack pointers (msp_s, msp_ns, psp_s, psp_ns), without security
	extensions and for other Cortex-M targets, there are 2 different
	stack pointers (msp and psp).

	With this patch, sp will always be in sync with one of the real stack
	pointers on Arm targets that contain more than one stack pointer.

	gdb/arm: Use if-else if instead of switch
	As the register numbers for the alternative Arm SP registers are not
	constant, it's not possible to use switch statement to define the
	rules.  In order to not have a mix, replace the few existing
	switch statements with regular if-else if statements

	gdb: handle dis_style_sub_mnemonic disassembler style

	      opcodes: add new sub-mnemonic disassembler style

	I added a new disassembler style dis_style_sub_mnemonic, but forgot to
	add GDB support for this style.  Fix this oversight in this commit.

2022-07-25  Andrew Burgess  <aburgess@redhat.com>

	libopcodes/ppc: add support for disassembler styling
	This commit adds disassembler styling to the libopcodes ppc
	disassembler.  This conversion was pretty straight forward, I just
	converted the fprintf_func calls to fprintf_styled_func calls and
	added an appropriate style.

	For testing the new styling I just assembled then disassembled the
	source files in gas/testsuite/gas/ppc and manually checked that the
	styling looked reasonable.

	I think the only slightly weird case was how things like '4*cr1+eq'
	are styled.  As best I can tell, this construct, used for example in
	this instruction:

	  crand   4*cr1+lt,4*cr1+gt,4*cr1+eq

	is used to access a field of a control register.  I initially tried
	styling this whole construct as a register[1], but during review it
	was suggested that instead different parts of the text should have
	different styles.  In this commit I propose styling '4*cr1+lt' like
	this:

	  4    - immediate,
	  *    - text,
	  cr1  - register
	  +    - text
	  lt   - sub-mnemonic

	If the user does not request styled output from objdump, then there
	should be no change in the disassembler output after this commit.

	opcodes: add new sub-mnemonic disassembler style
	When adding libopcodes disassembler styling support for AArch64, it
	feels like the results would be improved by having a new sub-mnemonic
	style.  This will be used in cases like:

	  add    w16, w7, w1, uxtb #2
	                      ^^^^----- Here

	And:

	  cinc   w0, w1, ne
	                 ^^----- Here

	This commit just adds the new style, and prepares objdump to handle
	the style.  A later commit will add AArch64 styling, and will actually
	make use of the style.

	As this style is currently unused, there should be no user visible
	changes after this commit.

	Re: PowerPC64 .branch_lt address
	On seeing PR29369 my suspicion was naturally on a recent powerpc64
	change, commit 0ab80031430e.  Without a reproducer, I spent time
	wondering what could have gone wrong, and while I doubt this patch
	would have fixed the PR, there are some improvements that can be made
	to cater for user silliness.

	I also noticed that when -z relro -z now sections are created out of
	order, with .got before .plt in the section headers but .got is laid
	out at a higher address.  That's due to the address expression for
	.branch_lt referencing SIZEOF(.got) and so calling init_os (which
	creates a bfd section) for .got before the .plt section is created.
	Fix that by ignoring SIZEOF in exp_init_os.  Unlike ADDR and LOADADDR
	which need to reference section vma and lma respectively, SIZEOF can
	and does cope with a missing bfd section by returning zero for its
	size, which of course is correct.

		PR 29369
		* ldlang.c (exp_init_os): Don't create a bfd section for SIZEOF.
		* emulparams/elf64ppc.sh (OTHER_RELRO_SECTIONS_2): Revise
		.branch_lt address to take into account possible user sections
		with alignment larger than 8 bytes.

	[gdb/symtab] Fix duplicate CUs in all_comp_units
	When running test-case gdb.cp/cpexprs-debug-types.exp with target board
	cc-with-debug-names on a system with gcc 12.1.1 (defaulting to dwarf 5), I
	run into:
	...
	(gdb) file cpexprs-debug-types^M
	Reading symbols from cpexprs-debug-types...^M
	warning: Section .debug_aranges in cpexprs-debug-types has duplicate \
	  debug_info_offset 0x0, ignoring .debug_aranges.^M
	gdb/dwarf2/read.h:309: internal-error: set_length: \
	  Assertion `m_length == length' failed.^M
	...

	The exec contains a .debug_names section, which gdb rejects due to
	.debug_names containing a list of TUs, while the exec doesn't contain a
	.debug_types section (which is what you'd expect for dwarf 4).

	Gdb then falls back onto the cooked index, which calls create_all_comp_units
	to create all_comp_units.  However, the failed index reading left some
	elements in all_comp_units, so we end up with duplicates in all_comp_units,
	which causes the misleading complaint and the assert.

	Fix this by:
	- asserting at the start of create_all_comp_units that all_comp_units is empty,
	  as we do in create_cus_from_index and create_cus_from_debug_names, and
	- cleaning up all_comp_units when failing in dwarf2_read_debug_names.

	Add a similar cleanup in dwarf2_read_gdb_index.

	Tested on x86_64-linux.

	gdb: ensure the cast in gdbarch_tdep is valid
	This commit makes use of gdb::checked_static_cast when casting the
	generic gdbarch_tdep pointer to a specific sub-class type.  This means
	that, when compiled in developer mode, GDB will validate that the cast
	is correct.

	In order to use gdb::checked_static_cast the types involved must have
	RTTI, which is why the gdbarch_tdep base class now has a virtual
	destructor.

	Assuming there are no bugs in GDB where we cast a gdbarch_tdep pointer
	to the wrong type, then there should be no changes after this commit.

	If any bugs do exist, then GDB will now assert (in a developer build).

2022-07-21  Andrew Burgess  <aburgess@redhat.com>

	gdbsupport: add checked_static_cast
	This commit was inspired by these mailing list posts:

	  https://sourceware.org/pipermail/gdb-patches/2022-June/190323.html
	  https://sourceware.org/pipermail/gdb-patches/2022-April/188098.html

	The idea is to add a new function gdb::checked_static_cast, which can,
	in some cases, be used as a drop-in replacement for static_cast.  And
	so, if I previously wrote this:

	  BaseClass *base = get_base_class_pointer ();
	  DerivedClass *derived = static_cast<DerivedClass *> (base);

	I can now write:

	  BaseClass *base = get_base_class_pointer ();
	  DerivedClass *derived = gdb::checked_static_cast<DerivedClass *> (base);

	The requirement is that BaseClass and DerivedClass must be
	polymorphic.

	The benefit of making this change is that, when GDB is built in
	developer mode, a run-time check will be made to ensure that `base`
	really is of type DerivedClass before the cast is performed.  If
	`base` is not of type DerivedClass then GDB will assert.

	In a non-developer build gdb::checked_static_cast is equivalent to a
	static_cast, and there should be no performance difference.

	This commit adds the support function, but does not make use of this
	function, a use will be added in the next commit.

	gdb: move the type cast into gdbarch_tdep
	I built GDB for all targets on a x86-64/GNU-Linux system, and
	then (accidentally) passed GDB a RISC-V binary, and asked GDB to "run"
	the binary on the native target.  I got this error:

	  (gdb) show architecture
	  The target architecture is set to "auto" (currently "i386").
	  (gdb) file /tmp/hello.rv32.exe
	  Reading symbols from /tmp/hello.rv32.exe...
	  (gdb) show architecture
	  The target architecture is set to "auto" (currently "riscv:rv32").
	  (gdb) run
	  Starting program: /tmp/hello.rv32.exe
	  ../../src/gdb/i387-tdep.c:596: internal-error: i387_supply_fxsave: Assertion `tdep->st0_regnum >= I386_ST0_REGNUM' failed.

	What's going on here is this; initially the architecture is i386, this
	is based on the default architecture, which is set based on the native
	target.  After loading the RISC-V executable the architecture of the
	current inferior is updated based on the architecture of the
	executable.

	When we "run", GDB does a fork & exec, with the inferior being
	controlled through ptrace.  GDB sees an initial stop from the inferior
	as soon as the inferior comes to life.  In response to this stop GDB
	ends up calling save_stop_reason (linux-nat.c), which ends up trying
	to read register from the inferior, to do this we end up calling
	target_ops::fetch_registers, which, for the x86-64 native target,
	calls amd64_linux_nat_target::fetch_registers.

	After this I eventually end up in i387_supply_fxsave, different x86
	based targets will end in different functions to fetch registers, but
	it doesn't really matter which function we end up in, the problem is
	this line, which is repeated in many places:

	  i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch);

	The problem here is that the ARCH in this line comes from the current
	inferior, which, as we discussed above, will be a RISC-V gdbarch, the
	tdep field will actually be of type riscv_gdbarch_tdep, not
	i386_gdbarch_tdep.  After this cast we are relying on undefined
	behaviour, in my case I happen to trigger an assert, but this might
	not always be the case.

	The thing I tried that exposed this problem was of course, trying to
	start an executable of the wrong architecture on a native target.  I
	don't think that the correct solution for this problem is to detect,
	at the point of cast, that the gdbarch_tdep object is of the wrong
	type, but, I did wonder, is there a way that we could protect
	ourselves from incorrectly casting the gdbarch_tdep object?

	I think that there is something we can do here, and this commit is the
	first step in that direction, though no actual check is added by this
	commit.

	This commit can be split into two parts:

	 (1) In gdbarch.h and arch-utils.c.  In these files I have modified
	 gdbarch_tdep (the function) so that it now takes a template argument,
	 like this:

	    template<typename TDepType>
	    static inline TDepType *
	    gdbarch_tdep (struct gdbarch *gdbarch)
	    {
	      struct gdbarch_tdep *tdep = gdbarch_tdep_1 (gdbarch);
	      return static_cast<TDepType *> (tdep);
	    }

	  After this change we are no better protected, but the cast is now
	  done within the gdbarch_tdep function rather than at the call sites,
	  this leads to the second, much larger change in this commit,

	  (2) Everywhere gdbarch_tdep is called, we make changes like this:

	    -  i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch);
	    +  i386_gdbarch_tdep *tdep = gdbarch_tdep<i386_gdbarch_tdep> (arch);

	There should be no functional change after this commit.

	In the next commit I will build on this change to add an assertion in
	gdbarch_tdep that checks we are casting to the correct type.

	gdb: select suitable thread for gdbarch_adjust_breakpoint_address
	The three targets that implement gdbarch_adjust_breakpoint_address are
	arm, frv, and mips.  In each of these targets the adjust breakpoint
	address function does some combination of reading the symbol table, or
	reading memory at the location the breakpoint could be placed.

	The problem is that performing these actions requires that the current
	inferior and program space be the one in which the breakpoint will be
	placed, and this is not currently always the case.

	Consider a GDB session with multiple inferiors.  One inferior might be
	a native target while another could be a remote target of a completely
	different architecture.  Alternatively, if we consider ARM and
	AArch64, one native inferior might be AArch64, while a second native
	inferior could be ARM.

	In these cases it is possible, and valid, for a user to have one
	inferior selected, and place a breakpoint in the other inferior by
	placing a breakpoint on a particular symbol.

	If this happens, then currently, when
	gdbarch_adjust_breakpoint_address is called, the wrong inferior (and
	program space) will be selected, and memory reads, and symbol look
	ups, will not return the expected results, this could lead to
	breakpoints being placed in the wrong location.

	There are currently two places where gdbarch_adjust_breakpoint_address
	is called:

	  1. In infrun.c, in the function handle_step_into_function.  In this
	  case, I believe that the correct inferior and program space will
	  already be selected as this is called as part of the stop event
	  handling, so I don't think we need to worry about this case, and

	  2. In breakpoint.c, in the function adjust_breakpoint_address, which
	  is itself called from code_breakpoint::add_location and
	  watch_command_1.

	  The watch_command_1 case I don't think we need to worry about, this
	  is for when a local watch expression is created, which can only be
	  in the currently selected inferior, so this case should be fine.

	  The code_breakpoint::add_location case is the one that needs fixing,
	  this is what allows a breakpoint to be created between inferiors.

	To fix the code_breakpoint::add_location case, I propose that we pass
	the "correct" program_space (i.e. the program space in which the
	breakpoint will be created) to the adjust_breakpoint_address function.
	Then in adjust_breakpoint_address we can make use of
	switch_to_program_space_and_thread to switch program_space and
	inferior before calling gdbarch_adjust_breakpoint_address.

	I discovered this issue while working on a later patch in this
	series.  This later patch will detect when we cast the result of
	gdbarch_tdep to the wrong type.

	With this later patch in place I ran gdb.multi/multi-arch.exp on an
	AArch64 target.  In this situation, two inferiors are created, an
	AArch64 inferior, and an ARM inferior.  The test selected the AArch64
	inferior and tries to create a breakpoint in the ARM inferior.

	As a result of this we end up in arm_adjust_breakpoint_address, which
	calls arm_pc_is_thumb.  Before this commit the AArch64 inferior would
	be current.  As a result, all of the checks in arm_pc_is_thumb would
	fail (they rely on reading symbols from the current program space),
	and so, at the end of arm_pc_is_thumb we would call
	arm_frame_is_thumb.  However, remember, at this point the current
	inferior is the AArch64 inferior, so the current frame is an AArch64
	frame.

	In arm_frame_is_thumb we call arm_psr_thumb_bit, which calls
	gdbarch_tdep and casts the result to arm_gdbarch_tdep.  This is wrong,
	the tdep field is of type aarch64_gdbarch_tdep.  After this we have
	undefined behaviour.

	With this patch in place, we will have switched to a thread in the ARM
	program space before calling arm_adjust_breakpoint_address.  As a
	result, we now succeed in looking up the required symbols in
	arm_pc_is_thumb, and so we never call arm_frame_is_thumb.

	However, in the worst case scenario, if we did end up calling
	arm_frame_is_thumb, as the current inferior should now be the ARM
	inferior, the current frame should be an ARM frame, so we still should
	not hit undefined behaviour.

	I have added an assert to arm_frame_is_thumb.

	gdb/mips: rewrite show_mask_address
	This commit is similar to the previous commit, but in this case GDB is
	actually relying on undefined behaviour.

	Consider building GDB for all targets on x86-64/GNU-Linux, then doing
	this:

	  (gdb) show mips mask-address
	  Zeroing of upper 32 bits of 64-bit addresses is auto.
	  The 32 bit address mask is set automatically.  Currently disabled
	  (gdb)

	The 'show mips mask-address' command ends up in show_mask_address in
	mips-tdep.c, and this function does this:

	  mips_gdbarch_tdep *tdep
	    = (mips_gdbarch_tdep *) gdbarch_tdep (target_gdbarch ());

	Later we might pass TDEP to mips_mask_address_p.  However, in my
	example above, on an x86-64 native target, the current target
	architecture will be an x86-64 gdbarch, and the tdep field within the
	gdbarch will be of type i386_gdbarch_tdep, not of type
	mips_gdbarch_tdep, as a result the cast above was incorrect, and TDEP
	is not pointing at what it thinks it is.

	I also think the current output is a little confusing, we appear to
	have two lines that show the same information, but using different
	words.

	The first line comes from calling deprecated_show_value_hack, while
	the second line is printed directly from show_mask_address.  However,
	both of these lines are printing the same mask_address_var value.  I
	don't think the two lines actually adds any value here.

	Finally, none of the text in this function is passed through the
	internationalisation mechanism.

	It would be nice to remove another use of deprecated_show_value_hack
	if possible, so this commit does a complete rewrite of
	show_mask_address.

	After this commit the output of the above example command, still on my
	x86-64 native target is:

	    (gdb) show mips mask-address
	    Zeroing of upper 32 bits of 64-bit addresses is "auto" (current architecture is not MIPS).

	The 'current architecture is not MIPS' text is only displayed when the
	current architecture is not MIPS.  If the architecture is mips then we
	get the more commonly seen 'currently "on"' or 'currently "off"', like
	this:

	  (gdb) set architecture mips
	  The target architecture is set to "mips".
	  (gdb) show mips mask-address
	  Zeroing of upper 32 bits of 64-bit addresses is "auto" (currently "off").
	  (gdb)

	All the text is passed through the internationalisation mechanism, and
	we only call gdbarch_tdep when we know the gdbarch architecture is
	bfd_arch_mips.

	gdb/arm: move fetch of arm_gdbarch_tdep to a more inner scope
	This is a small refactor to resolve an issue before it becomes a
	problem in a later commit.

	Move the fetching of an arm_gdbarch_tdep into a more inner scope
	within two functions in arm-tdep.c.

	The problem with the current code is that the functions in question
	are used as the callbacks for two set/show parameters.  These set/show
	parameters are available no matter the current architecture, but are
	really about controlling an ARM architecture specific setting.  And
	so, if I build GDB for all targets on an x86-64/GNU-Linux system, I
	can still do this:

	  (gdb) show arm fpu
	  (gdb) show arm abi

	After these calls we end up in show_fp_model and arm_show_abi
	respectively, where we unconditionally do this:

	  arm_gdbarch_tdep *tdep
	    = (arm_gdbarch_tdep *) gdbarch_tdep (target_gdbarch ());

	However, the gdbarch_tdep() result will only be a arm_gdbarch_tdep if
	the current architecture is ARM, otherwise the result will actually be
	of some other type.

	This isn't actually a problem, as in both cases the use of tdep is
	guarded by a later check that the gdbarch architecture is
	bfd_arch_arm.

	This commit just moves the call to gdbarch_tdep() after the
	architecture check.

	In a later commit gdbarch_tdep() will be able to spot when we are
	casting the result to the wrong type, and this function will trigger
	assertion failures if things are not fixed.

	There should be not user visible changes after this commit.

	[gdb/symtab] Fix bad compile unit index complaint
	I noticed this code in dw2_debug_names_iterator::next:
	...
	        case DW_IDX_compile_unit:
	          /* Don't crash on bad data.  */
	          if (ull >= per_bfd->all_comp_units.size ())
	            {
	              complaint (_(".debug_names entry has bad CU index %s"
	                           " [in module %s]"),
	                         pulongest (ull),
	                         objfile_name (objfile));
	              continue;
	            }
	          per_cu = per_bfd->get_cu (ull);
	          break;
	...

	This code used to DTRT, before we started keeping both CUs and TUs in
	all_comp_units.

	Fix by using "per_bfd->all_comp_units.size () - per_bfd->tu_stats.nr_tus"
	instead.

	It's hard to produce a test-case for this, but let's try at least to trigger
	the complaint somehow.  We start out by creating an exec with .debug_types and
	.debug_names:
	...
	$ gcc -g ~/hello.c -fdebug-types-section
	$ gdb-add-index -dwarf-5 a.out
	...
	and verify that we don't see any complaints:
	...
	$ gdb -q -batch -iex "set complaints 100" ./a.out
	...

	We look at the CU and TU table using readelf -w and conclude that we have
	nr_cus == 6 and nr_tus == 1.

	Now override ull in dw2_debug_names_iterator::next for the DW_IDX_compile_unit
	case to 6, and we have:
	...
	$ gdb -q -batch -iex "set complaints 100" ./a.out
	During symbol reading: .debug_names entry has bad CU index 6 [in module a.out]
	...

	After this, it still crashes because this code in
	dw2_debug_names_iterator::next:
	...
	  /* Skip if already read in.  */
	  if (m_per_objfile->symtab_set_p (per_cu))
	    goto again;
	...
	is called with per_cu == nullptr.

	Fix this by skipping the entry if per_cu == nullptr.

	Now revert the fix and observe that the complaint disappears, so we've
	confirmed that the fix is required.

	A somewhat similar issue for .gdb_index in dw2_symtab_iter_next has been filed
	as PR29367.

	Tested on x86_64-linux, with native and target board cc-with-debug-names.

	Handle Python 3.11 deprecation of PySys_SetPath and Py_SetProgramName
	Python 3.11 deprecates PySys_SetPath and Py_SetProgramName.  The
	PyConfig API replaces these and other functions.  This commit uses the
	PyConfig API to provide equivalent functionality while also preserving
	support for older versions of Python, i.e. those before Python 3.8.

	A beta version of Python 3.11 is available in Fedora Rawhide.  Both
	Fedora 35 and Fedora 36 use Python 3.10, while Fedora 34 still used
	Python 3.9.  I've tested these changes on Fedora 34, Fedora 36, and
	rawhide, though complete testing was not possible on rawhide due to
	a kernel bug.  That being the case, I decided to enable the newer
	PyConfig API by testing PY_VERSION_HEX against 0x030a0000.  This
	corresponds to Python 3.10.

	We could try to use the PyConfig API for Python versions as early as 3.8,
	but I'm reluctant to do this as there may have been PyConfig related
	bugs in earlier versions which have since been fixed.  Recent linux
	distributions should have support for Python 3.10.  This should be
	more than adequate for testing the new Python initialization code in
	GDB.

	Information about the PyConfig API as well as the motivation behind
	deprecating the old interface can be found at these links:

	https://github.com/python/cpython/issues/88279
	https://peps.python.org/pep-0587/
	https://docs.python.org/3.11/c-api/init_config.html

	The v2 commit also addresses several problems that Simon found in
	the v1 version.

	In v1, I had used Py_DontWriteBytecodeFlag in the new initialization
	code, but Simon pointed out that this global configuration variable
	will be deprecated in Python 3.12.  This version of the patch no longer
	uses Py_DontWriteBytecodeFlag in the new initialization code.
	Additionally, both Py_DontWriteBytecodeFlag and Py_IgnoreEnvironmentFlag
	will no longer be used when building GDB against Python 3.10 or higher.
	While it's true that both of these global configuration variables are
	deprecated in Python 3.12, it makes sense to disable their use for
	gdb builds against 3.10 and higher since those are the versions for
	which the PyConfig API is now being used by GDB.  (The PyConfig API
	includes different mechanisms for making the same settings afforded
	by use of the soon-to-be deprecated global configuration variables.)

	Simon also noted that PyConfig_Clear() would not have be called for
	one of the failure paths.  I've fixed that problem and also made the
	rest of the "bail out" code more direct.  In particular,
	PyConfig_Clear() will always be called, both for success and failure.

	The v3 patch addresses some rebase conflicts related to module
	initialization .  Commit 3acd9a692dd ("Make 'import gdb.events' work")
	uses PyImport_ExtendInittab instead of PyImport_AppendInittab.  That
	commit also initializes a struct for each module to import.  Both the
	initialization and the call to were moved ahead of the ifdefs to avoid
	having to replicate (at least some of) the code three times in various
	portions of the ifdefs.

	GNU/Linux), if you use the "step N" (or "stepi/next/nexti N") to step
	a thread a number of times:

	 (gdb) help step
	 step, s
	 Step program until it reaches a different source line.
	 Usage: step [N]
	 Argument N means step N times (or till program stops for another reason).

	... GDB prematurely stops all threads after the first step, and
	doesn't re-resume them for the subsequent N-1 steps.  It's as if for
	the 2nd and subsequent steps, the command was running with
	scheduler-locking enabled.

	This can be observed with the testcase added by this commit, which
	looks like this:

	 static pthread_barrier_t barrier;

	 static void *
	 thread_func (void *arg)
	 {
	   pthread_barrier_wait (&barrier);
	   return NULL;
	 }

	 int
	 main ()
	 {
	   pthread_t thread;
	   int ret;

	   pthread_barrier_init (&barrier, NULL, 2);

	   /* We run to this line below, and then issue "next 3".  That should
	      step over the 3 lines below and land on the return statement.  If
	      GDB prematurely stops the thread_func thread after the first of
	      the 3 nexts (and never resumes it again), then the join won't
	      ever return.  */
	   pthread_create (&thread, NULL, thread_func, NULL); /* set break here */
	   pthread_barrier_wait (&barrier);
	   pthread_join (thread, NULL);

	   return 0;
	 }

	The test hangs and times out without the GDB fix:

	 (gdb) next 3
	 [New Thread 0x7ffff7d89700 (LWP 525772)]
	 FAIL: gdb.threads/step-N-all-progress.exp: non-stop=off: target-non-stop=on: next 3 (timeout)

	The problem is a core gdb bug.

	When you do "step/stepi/next/nexti N", GDB internally creates a
	thread_fsm object and associates it with the stepping thread.  For the
	stepping commands, the FSM's class is step_command_fsm.  That object
	is what keeps track of how many steps are left to make.  When one step
	finishes, handle_inferior_event calls stop_waiting and returns, and
	then fetch_inferior_event calls the "should_stop" method of the event
	thread's FSM.  The implementation of that method decrements the
	steps-left counter.  If the counter is 0, it returns true and we
	proceed to presenting the stop to the user.  If it isn't 0 yet, then
	the method returns false, indicating to fetch_inferior_event to "keep
	going".

	Focusing now on when the first step finishes -- we're in "all-stop"
	mode, with the target in non-stop mode.  When a step finishes,
	handle_inferior_event calls stop_waiting, which itself calls
	stop_all_threads to stop everything.  I.e., after the first step
	completes, all threads are stopped, before handle_inferior_event
	returns.  And after that, now in fetch_inferior_event, we consult the
	thread's thread_fsm::should_stop, which as we've seen, for the first
	step returns false -- i.e., we need to keep_going for another step.
	However, since the target is in non-stop mode, keep_going resumes
	_only_ the current thread.  All the other threads remain stopped,
	inadvertently.

	If the target is in non-stop mode, we don't actually need to stop all
	threads right after each step finishes, and then re-resume them again.
	We can instead defer stopping all threads until all the steps are
	completed.

	So fix this by delaying the stopping of all threads until after we
	called the FSM's "should_stop" method.  I.e., move it from
	stop_waiting, to handle_inferior_events's callers,
	fetch_inferior_event and wait_for_inferior.

	New test included.  Tested on x86-64 GNU/Linux native and gdbserver.

	x86: Make protected symbols local for -shared
	Call _bfd_elf_symbol_refs_local_p with local_protected==true.  This has
	2 noticeable effects for -shared:

	* GOT-generating relocations referencing a protected data symbol no
	  longer lead to a GLOB_DAT (similar to a hidden symbol).
	* Direct access relocations (e.g. R_X86_64_PC32) no longer has the
	  confusing diagnostic below.

	    __attribute__((visibility("protected"))) void *foo() {
	      return (void *)foo;
	    }

	    // gcc -fpic -shared -fuse-ld=bfd
	    relocation R_X86_64_PC32 against protected symbol `foo' can not be used when making a shared object

	The new behavior matches arm, aarch64 (commit
	83c325007c5599fa9b60b8d5f7b84842160e1d1b), and powerpc ports, and other
	linkers: gold and ld.lld.

	Note: if some code tries to use direct access relocations to take the
	address of foo, the pointer equality will break, but the error should be
	reported on the executable link, not on the innocent shared object link.
	glibc 2.36 will give a warning at relocation resolving time.

	With this change, `#define elf_backend_extern_protected_data 1` is no
	longer effective.  Just remove it.

	Remove the test "Run protected-func-1 without PIE" since -fno-pic
	address taken operation in the executable doesn't work with protected
	symbol in a shared object by default.  Similarly, remove
	protected-data-1a and protected-data-1b.  protected-data-1b can be made
	working by removing HAVE_LD_PIE_COPYRELOC from GCC
	(https://sourceware.org/pipermail/gcc-patches/2022-June/596678.html).

	[AArch64] MTE corefile support
	Teach GDB how to dump memory tags for AArch64 when using the gcore command
	and how to read memory tag data back from a core file generated by GDB
	(via gcore) or by the Linux kernel.

	The format is documented in the Linux Kernel documentation [1].

	Each tagged memory range (listed in /proc/<pid>/smaps) gets dumped to its
	own PT_AARCH64_MEMTAG_MTE segment. A section named ".memtag" is created for each
	of those segments when reading the core file back.

	To save a little bit of space, given MTE tags only take 4 bits, the memory tags
	are stored packed as 2 tags per byte.

	When reading the data back, the tags are unpacked.

	I've added a new testcase to exercise the feature.

	Build-tested with --enable-targets=all and regression tested on aarch64-linux
	Ubuntu 20.04.

	[AArch64] Support AArch64 MTE memory tag dumps in core files
	The Linux kernel can dump memory tag segments to a core file, one segment
	per mapped range. The format and documentation can be found in the Linux
	kernel tree [1].

	The following patch adjusts bfd and binutils so they can handle this new
	segment type and display it accordingly. It also adds code required so GDB
	can properly read/dump core file data containing memory tags.

	Upon reading, each segment that contains memory tags gets mapped to a
	section named "memtag". These sections will be used by GDB to lookup the tag
	data. There can be multiple such sections with the same name, and they are not
	numbered to simplify GDB's handling and lookup.

	There is another patch for GDB that enables both reading
	and dumping of memory tag segments.

	Tested on aarch64-linux Ubuntu 20.04.

	gdb/python: look for python, then python 3 at configure time
	It is possible that a system might have a python3 executable, but no
	python executable.  For example, on my Fedora system the python2
	package provides /usr/bin/python2, the python3 package provides
	/usr/bin/python3, and the python-unversioned-command package provides
	/usr/bin/python, which picks between python2 and python3.

	It is quite possible to only have python3 available on a system.

	Currently, when GDB configures, it looks for a 'python' executable.
	If non is found then GDB will be built without python support.  Or the
	user needs to configure using --with-python=/usr/bin/python3.

	This commit updates GDB's configure.ac script to first look for
	'python', and then 'python3'.  Now, on a system that only has a
	python3 executable, GDB will automatically find, and use that in order
	to provide python support, no user supplied configure arguments are
	needed.

	I've tested this on my local machine by removing the
	python-unversioned-command package, confirming that there is no longer
	a 'python' executable in my $PATH, and then rebuilding GDB from
	scratch.  GDB with this patch has python support.

	Note that there are 4 active threads, and scheduling elts_per_thread on each

	gdb-add-index always generates an error when libdebuginfod wasn't compiled in
	gdb-add-index runs gdb with -iex 'set debuginfod enabled off'.  If gdb
	is not compiled against libdebuginfod this causes an unnecessary error
	message to be printed to stderr indicating that gdb was not built with
	debuginfod support.

	Fix this by changing the 'set debuginfod enabled off' command to a
	no-op when gdb isn't built with libdebuginfod.

	gdb/testsuite: modernize gdb.base/maint.exp
	gdb.base/maint.exp was using several gdb_expect statements, probably
	because this test case predates the existance of gdb_test_multiple. This
	commit updates the test case to use gdb_test_multiple, making it more
	resilient to internal errors and such.

	The only gdb_expect left in the testcase is one that specifically looks
	for an internal error being triggered as a PASS.

	PowerPC: Add support for IEEE 128-bit format.
	The test gdb.base/infcall-nested-structs-c.exp fails on a gdb assert
	in function ppc64_sysv_abi_return_value in file gdb/ppc-sysv-tdep.c.  The
	assert is due to the missing IEEE 128-bit support in file
	gdb/ppc-sysv-tdep.c.

	The IBM long double was the initial float 128-bit support added by IBM
	The IEEE 128-bit support, which is similar IBM long double support, was
	made the default starting with GCC 12.  The floating point format
	differences include the number of bits used to encode the exponent
	and significand.  Also, IBM long double values are passed in a pair of
	floating point registers.  The  IEEE 128-bit value is passed in a single
	vector register.

	This patch fixes the gdb_assert (ok); in function
	ppc64_sysv_abi_return_value in gdb/ppc-sysv-tdep.c by adding IEEE FLOAT
	128-bit type support for PowerPC.

	The patch has been tested on Power 10, ELFv2.  It fixes the following list
	of regression failures on Power 10:

	gdb.base/infcall-nested-structs-c.exp      192
	gdb.base/infcall-nested-structs-c++.exp     76
	gdb.base/structs.exp                         9

	The patch has been tested on Power 8 BE which is ELFv1.

	Add 'summary' mode to Value.format_string
	This adds a 'summary' mode to Value.format_string and to
	gdb.print_options.  For the former, it lets Python code format values
	using this mode.  For the latter, it lets a printer potentially detect
	if it is being called in a backtrace with 'set print frame-arguments'
	set to 'scalars'.

	I considered adding a new mode here to let a pretty-printer see
	whether it was being called in a 'backtrace' context at all, but I'm
	not sure if this is really desirable.

	Expose current 'print' settings to Python
	PR python/17291 asks for access to the current print options.  While I
	think this need is largely satisfied by the existence of
	Value.format_string, it seemed to me that a bit more could be done.

	First, while Value.format_string uses the user's settings, it does not
	react to temporary settings such as "print/x".  This patch changes
	this.

	Second, there is no good way to examine the current settings (in
	particular the temporary ones in effect for just a single "print").
	This patch adds this as well.

	PowerPC: fix for gdb.base/eh_return.exp
	Disable the Traceback Table generation on PowerPC for this test.  The
	Traceback Table consists of a series of bit fields to indicate things like
	the Traceback Table version, language, and specific information about the
	function.  The Traceback Table is generated following the end of the code
	for every function by default.  The Traceback Table is defined in the
	PowerPC ELF ABI and is intended to support debuggers and exception
	handlers.  The Traceback Table is displayed in the disassembly of functions
	by default and is part of the function length.  The table is typically
	interpreted by the disassembler as data represented by .long xxx entries.

	Generation of the Traceback Table is disabled in this test using the
	PowerPC specific gcc compiler option -mtraceback=no, the xlc option
	additional_flags-qtable=none and the clang optons
	 -mllvm -xcoff-traceback-table=false.  Disabling the Traceback Table
	generation in this test results in the gdb_test_multiple statement
	correctly locating the address of the bclr instruction before the statement
	"End of assembler dump." in the disassembly output.

	Tighten gdb.threads/no-unwaited-for-left.exp regexps
	A WIP version of a patch

	 The current thread <Thread ID 1> has terminated.  See `help thread'.
	 (gdb) PASS: gdb.threads/no-unwaited-for-left.exp: only thread 3 left, main thread terminated

	Somehow, above, GDB re-added the zombie leader back before printing
	"No unwaited-for children left.".  The "only thread 3 left, main
	thread terminated" test should have caught this, but didn't.  That is
	because the test's regexp has a ".*" after the part that matches
	thread 3.  This commit tightens that regexp to catch such a bug.  It
	also tightens the "only main thread left, thread 2 terminated" test's
	regexp in the same way.

	Fix "until LINE" in main, when "until" runs into longjmp
	With a test like this:

	1       #include <dlfcn.h>
	2       int
	3       main ()
	4       {
	5          dlsym (RTLD_DEFAULT, "FOO");
	6          return 0;
	7       }

	and then "start" followed by "until 6", GDB currently incorrectly
	stops inside the runtime loader, instead of line 6.  Vis:

	  ...
	  Temporary breakpoint 1, main () at until.c:5
	  4       {
	  (gdb) until 6
	  0x00007ffff7f0a90d in __GI__dl_catch_exception (exception=exception@entry=0x7fffffffdb00, operate=<optimized out>, args=0x7ffff7f0a90d <__GI__dl_catch_exception+109>) at dl-error-skeleton.c:206
	  206     dl-error-skeleton.c: No such file or directory.
	  (gdb)

	The problem is related to longjmp handling -- dlsym internally
	longjmps on error.  The testcase can be reduced to this:

	1       #include <setjmp.h>
	2       void func () {
	3         jmp_buf buf;
	4         if (setjmp (buf) == 0)
	5           longjmp (buf, 1);
	6       }
	7
	8       int main () {
	9         func ();
	10        return 0; /* until to here */
	11      }

	and then with "start" followed by "until 10", GDB currently
	incorrectly stops at line 4 (returning from setjmp), instead of line
	10.

	The problem is that the BPSTAT_WHAT_CLEAR_LONGJMP_RESUME code in
	infrun.c fails to find the initiating frame, and so infrun thinks that
	the longjmp jumped somewhere outer to "until"'s originating frame.

	Here:

	    case BPSTAT_WHAT_CLEAR_LONGJMP_RESUME:
	      {
		struct frame_info *init_frame;

		/* There are several cases to consider.

		   1. The initiating frame no longer exists.  In this case we
		   must stop, because the exception or longjmp has gone too
		   far.

	        ...

		init_frame = frame_find_by_id (ecs->event_thread->initiating_frame);

		if (init_frame)   // this is NULL!
		  {
		     ...
		  }

		/* For Cases 1 and 2, remove the step-resume breakpoint, if it
		   exists.  */
		delete_step_resume_breakpoint (ecs->event_thread);

		end_stepping_range (ecs);   // case 1., so we stop.
	      }

	The initiating frame is set by until_break_command ->
	set_longjmp_breakpoint.  The initiating frame is supposed to be the
	frame that is selected when the command was issued, but
	until_break_command instead passes the frame id of the _caller_ frame
	by mistake.  When the "until LINE" command is issued from main, the
	caller frame is the caller of main.  When later infrun tries to find
	that frame by id, it fails to find it, because frame_find_by_id
	doesn't unwind past main.

	The bug is that we passed the caller frame's id to
	set_longjmp_breakpoint.  We should have passed the selected frame's id
	instead.

	[gdb/symtab] Add dwarf2_cu::lang ()
	The cu->per_cu->lang field was added to carry information from the initial
	partial symtabs phase to the symtab expansion phase, for the benefit of a
	particular optimization in process_imported_unit_die.

	Other uses have been added, but since the first phase now has been
	parallelized, those have become problematic and sources of race conditions.

	Fix this by adding dwarf2_cu::lang () and using it where we can to replace
	cu->per_cu->lang () with cu->lang ().

	Also assert in dwarf2_cu::lang () that we're not returning language_unknown.

	Tested on x86_64-linux.

	The problem is that the written fields are part of the same memory location as
	the read fields, so executing a read and write in different threads is
	undefined behavour.

	Making the written fields separate memory locations, using the new

	The set of fields has been established experimentally to be the
	minimal set to get rid of this type of -fsanitize=thread errors, but
	more fields might require the same treatment.

	Looking at the properties of the lang field, unlike dwarf_version it's
	not available in the unit header, so it will be set the first time
	during the parallel cooked index reading.  The same holds for
	unit_type, and likewise for addresses_seen.

	dwarf2_per_cu_data::addresses_seen is moved so that the bitfields that
	currently follow it can be merged in the same memory location as the
	bitfields that currently precede it, for better packing.

	Tested on x86_64-linux.

	Introduce struct packed template
	When building gdb with -fsanitize=thread and gcc 12, and running test-case
	gdb.dwarf2/dwz.exp, we run into a few data races.  For example, between:

	 ...
	   Write of size 1 at 0x7b200000300e by thread T4:
	     #0 process_psymtab_comp_unit gdb/dwarf2/read.c:6789 (gdb+0x830720)
	 ...

	and:

	 ...
	   Previous read of size 1 at 0x7b200000300e by main thread:
	     #0 cutu_reader::cutu_reader(dwarf2_per_cu_data*, dwarf2_per_objfile*, \
	     abbrev_table*, dwarf2_cu*, bool, abbrev_cache*) gdb/dwarf2/read.c:6164 \
	     (gdb+0x82edab)
	 ...

	In other words, between:

	 ...
	       this_cu->unit_type = DW_UT_partial;
	 ...

	and:

	 ...
	   if (this_cu->reading_dwo_directly)
	 ...

	The problem is that the written fields are part of the same memory
	location as the read fields, so executing a read and write in
	different threads is undefined behavour.

	Making the written fields separate memory locations, like this:

	...
	  struct {
	    ENUM_BITFIELD (dwarf_unit_type) unit_type : 8;
	  };
	...

	fixes it, however that also increases the size of struct
	dwarf2_per_cu_data, because it introduces padding due to alignment of
	these new structs, which align on the natural alignment of the
	specified type of their fields.  We can fix that with
	__attribute__((packed)), like so:

	  struct {
	    ENUM_BITFIELD (dwarf_unit_type) unit_type : 8 __attribute__((packed));
	  };

	but to avoid having to write that in several places and add suitable
	comments explaining how that concoction works, introduce a new struct
	packed template that wraps/hides this.  Instead of the above, we'll be
	able to write:

	    packed<dwarf_unit_type, 1> unit_type;

	Note that we can't change the type of dwarf_unit_type, as that is
	defined in include/, and shared with other projects, some of those
	written in C.

	This patch just adds the struct packed type.  Following patches will
	make use of it.  One of those patches will want to wrap a struct
	packed in an std::atomic, like:

	  std::atomic<std::packed<language, 1>> m_lang;

	so the new gdbsupport/packed.h header adds some operators to make
	comparisions between that std::atomic and the type that the wrapped
	struct packed wraps work, like in:

	   if (m_lang == language_c)

	It would be possible to implement struct packed without using
	__attribute__((packed)), by having it store an array of bytes of the
	appropriate size instead, however that would make it less convenient
	to debug GDB.  The way it's implemented, printing a struct packed
	variable just prints its field using its natural type, which is
	particularly useful if the type is an enum.  I believe that
	__attribute__((packed)) is supported by all compilers that are able to
	build GDB.  Even a few BFD headers use on ATTRIBUTE_PACKED on external
	types:

	 include/coff/external.h:  } ATTRIBUTE_PACKED
	 include/coff/external.h:} ATTRIBUTE_PACKED ;
	 include/coff/external.h:} ATTRIBUTE_PACKED ;
	 include/coff/pe.h:} ATTRIBUTE_PACKED ;
	 include/coff/pe.h:} ATTRIBUTE_PACKED;
	 include/elf/external.h:} ATTRIBUTE_PACKED  Elf_External_Versym;

	It is not possible to build GDB with MSVC today, but if it could, that
	would be one compiler that doesn't support this attribute.  However,
	it supports packing via pragmas, so there's a way to cross that bridge
	if we ever get to it.  I believe any compiler worth its salt supports
	some way of packing.

	In any case, the worse that happens without the attribute is that some
	types become larger than ideal.  Regardless, I've added a couple
	static assertions to catch such compilers in action:

	    /* Ensure size and aligment are what we expect.  */
	    gdb_static_assert (sizeof (packed) == Bytes);
	    gdb_static_assert (alignof (packed) == 1);

	PR29355, ld segfaults with -r/-q and custom-named section .rela*
	The bug testcase uses an output section named .rel or .rela which has

	relocations.  When counting output relocations SHT_REL and SHT_RELA
	section reloc_count is ignored, with the justification that reloc
	sections themselves can't have relocations and some backends use
	reloc_count in reloc sections.  However, the test wrongly used the

	.rel/.rela section type as SHT_REL/SHT_RELA when non-empty non-reloc
	sections are written to it, but I'm not going to change that since it

	Always emit =thread-exited notifications, even if silent
	[Note: the testcased added by this commit depends on
	https://sourceware.org/pipermail/gdb-patches/2022-June/190259.html,
	otherwise GDB just crashes when detaching the core]

	Currently, in MI, =thread-created are always emitted, like:

	 =thread-group-started,id="i1",pid="195680"
	 =thread-created,id="1",group-id="i1"
	 ...

	but on teardown, if the target uses exit_inferior_silent, then you'll
	only see the inferior exit notification (thread-group-exited), no
	notification for threads.

	The core target is one of the few targets that use
	exit_inferior_silent.  Here's an example session:

	 -target-select core $corefile
	 =thread-group-started,id="i1",pid="195680"
	 =thread-created,id="1",group-id="i1"
	 ...
	 ^connected,frame=....
	 (gdb)
	 -target-detach
	 =thread-group-exited,id="i1"
	 ^done
	 (gdb)

	This imbalance of emitting =thread-created but then not =thread-exited
	seems off to me.  (And, it complicates changes I want to do to
	centralize emitting thread exit notifications for the CLI, which is
	why I'm looking at this.)

	And then, since most other targets use exit_inferior instead of
	exit_inferior_silent, MI is already emitting =thread-exited
	notifications when tearing down an inferior, for most targets.

	This commit makes MI always emit the =thread-exited notifications,
	even for exit_inferior_silent.

	Afterwards, when debugging a core, MI outputs:

	 (gdb)
	 -target-detach
	 =thread-exited,id="1",group-id="i1"    << new line
	 =thread-group-exited,id="i1"
	 ^done
	 (gdb)

	Surprisingly, there's no MI testcase debugging a core file.  This
	commit adds the first.

	       if (proc_target->commit_resumed_state)
	           ^^^^^^^^^^^

	With 'proc_target' above being null.  all_non_exited_inferiors filters
	out inferiors that have pid==0.  We get here at the end of
	detach_command, after core_target::detach has already run, at which
	point the inferior _should_ have pid==0 and no process target.  It is
	clear it no longer has a process target, but, it still has a pid!=0
	somehow.

	The reason the inferior still has pid!=0, is that core_target::detach
	just unpushes, and relies on core_target::close to actually do the
	getting rid of the core and exiting the inferior.  The problem with
	that is that detach_command grabs an extra strong reference to the
	process stratum target, so the unpush_target inside
	core_target::detach doesn't actually result in a call to
	core_target::close.

	Fix this my moving the cleaning up the core inferior to a shared
	routine called by both core_target::close and core_target::detach.  We
	still need to cleanup the inferior from within core_file::close
	because there are paths to it that want to get rid of the core without
	going through detach.  E.g., "core-file" -> "run".

	This commit includes a new test added to gdb.base/corefile.exp to
	cover the "core-file core" -> "detach" scenario.

	gdb: add support for disassembler styling using libopcodes
	This commit extends GDB to make use of libopcodes styling support
	where available, currently this is just i386 based architectures, and
	RISC-V.

	For architectures that don't support styling using libopcodes GDB will
	fall back to using the Python Pygments package, when the package is
	available.

	The new libopcodes based styling has the disassembler identify parts
	of the disassembled instruction, e.g. registers, immediates,
	mnemonics, etc, and can style these components differently.
	Additionally, as the styling is now done in GDB we can add settings to
	allow the user to configure which colours are used right from the GDB
	CLI.

	There's some new maintenance commands:

	  maintenance set libopcodes-styling enabled on|off
	  maintenance show libopcodes-styling

	These can be used to manually disable use of libopcodes styling.  This
	is a maintenance command as it's not anticipated that a user should
	need to do this.  But, this could be useful for testing, or, in some
	rare cases, a user might want to override the Python hook used for
	disassembler styling, and then disable libopcode styling so that GDB
	falls back to using Python.  Right now I would consider this second
	use case a rare situation, which is why I think a maintenance command
	is appropriate.

	When libopcodes is being used for styling then the user can make use
	of the following new styles:

	  set/show style disassembler comment
	  set/show style disassembler immediate
	  set/show style disassembler mnemonic
	  set/show style disassembler register

	The disassembler also makes use of the 'address' and 'function'
	styles to style some parts of the disassembler output.  I have also
	added the following aliases though:

	  set/show style disassembler address
	  set/show style disassembler symbol

	these are aliases for:

	  set/show style address
	  set/show style function

	respectively, and exist to make it easier for users to discover
	disassembler related style settings.  The 'address' style is used to
	style numeric addresses in the disassembler output, while the 'symbol'
	or 'function' style is used to style the names of symbols in
	disassembler output.

	As not every architecture supports libopcodes styling, the maintenance
	setting 'libopcodes-styling enabled' has an "auto-off" type behaviour.
	Consider this GDB session:

	  (gdb) show architecture
	  The target architecture is set to "auto" (currently "i386:x86-64").
	  (gdb) maintenance show libopcodes-styling enabled
	  Use of libopcodes styling support is "on".

	the setting defaults to "on" for architectures that support libopcodes
	based styling.

	  (gdb) set architecture sparc
	  The target architecture is set to "sparc".
	  (gdb) maintenance show libopcodes-styling enabled
	  Use of libopcodes styling support is "off" (not supported on architecture "sparc")

	the setting will show as "off" if the user switches to an architecture
	that doesn't support libopcodes styling.  The underlying setting is
	still "on" at this point though, if the user switches back to
	i386:x86-64 then the setting would go back to being "on".

	  (gdb) maintenance set libopcodes-styling enabled off
	  (gdb) maintenance show libopcodes-styling enabled
	  Use of libopcodes styling support is "off".

	now the setting is "off" for everyone, even if the user switches back
	to i386:x86-64 the setting will still show as "off".

	  (gdb) maintenance set libopcodes-styling enabled on
	  Use of libopcodes styling not supported on architecture "sparc".
	  (gdb) maintenance show libopcodes-styling enabled
	  Use of libopcodes styling support is "off".

	attempting to switch the setting "on" for an unsupported architecture
	will give an error, and the setting will remain "off".

	  (gdb) set architecture auto
	  The target architecture is set to "auto" (currently "i386:x86-64").
	  (gdb) maintenance show libopcodes-styling enabled
	  Use of libopcodes styling support is "off".
	  (gdb) maintenance set libopcodes-styling enabled on
	  (gdb) maintenance show libopcodes-styling enabled
	  Use of libopcodes styling support is "on".

	the user will need to switch back to a supported architecture before
	they can one again turn this setting "on".

	passed as an argument to the fprintf_func and fprintf_styled_func
	callbacks when the disassembler wants to print anything.

	Previously, GDB would store a pointer to a ui_file object in the
	'stream' field, then, when the disassembler wanted to print anything,
	the content would be written to the ui_file object.  An example of an
	fprintf_func callback, from gdb/disasm.c is:

	  int
	  gdb_disassembler::dis_asm_fprintf (void *stream, const char *format, ...)
	  {
	    /* Write output to STREAM here.  */
	  }

	This is fine, but has one limitation, within the print callbacks we
	only have access to STREAM, we can't access any additional state
	stored within the gdb_disassemble_info object.

	Right now this isn't a problem, but in a future commit this will
	become an issue, how we style the output being written to STREAM will
	depend on the state of the gdb_disassemble_info object, and this state
	might need to be updated, depending on what is being printed.

	In this commit I propose changing the 'stream' field of the
	disassemble_info to carry a pointer to the gdb_disassemble_info
	sub-class, rather than the stream itself.

	We then have the two sub-classes of gdb_disassemble_info to consider,
	the gdb_non_printing_disassembler class never cared about the stream,
	previously, for this class, the stream was nullptr.  With the change
	to make stream be a gdb_disassemble_info pointer, no further updates
	are needed for gdb_non_printing_disassembler.

	The other sub-class is gdb_printing_disassembler.  In this case the
	sub-class now carries around a pointer to the stream object.  The
	print callbacks are updated to cast the incoming stream object back to
	a gdb_printing_disassembler, and then extract the stream.

	This is purely a refactoring commit.  A later commit will add
	additional state to the gdb_printing_disassembler, and update the
	print callbacks to access this state.

	There should be no user visible changes after this commit.

	[gdb/symtab] Fix data race in per_cu->length
	With gdb build with -fsanitize=thread and test-case
	gdb.dwarf2/dw4-sig-types.exp and target board cc-with-dwz-m we run into a data
	race between:
	...
	  Write of size 4 at 0x7b2800002268 by thread T4:^M
	    #0 cutu_reader::cutu_reader(dwarf2_per_cu_data*, dwarf2_per_objfile*, \
	    abbrev_table*, dwarf2_cu*, bool, abbrev_cache*) gdb/dwarf2/read.c:6236 \
	    (gdb+0x82f525)^M
	...
	and this read:
	...
	  Previous read of size 4 at 0x7b2800002268 by thread T1:^M
	    #0 dwarf2_find_containing_comp_unit gdb/dwarf2/read.c:23444 \
	    (gdb+0x86e22e)^M
	...

	In other words, between this write:
	...
		    this_cu->length = cu->header.get_length ();
	...
	and this read:
	...
		      && mid_cu->sect_off + mid_cu->length > sect_off))
	...
	of per_cu->length.

	Fix this similar to the per_cu->dwarf_version case, by only setting it if
	needed, and otherwise verifying that the same value is used.  [ Note that the
	same code is already present in the other cutu_reader constructor. ]

	Move this logic into into a member function set_length to make sure it's used
	consistenly, and make the field private in order to enforce access through the
	member functions, and rename it to m_length.

	This exposes (running test-case gdb.dwarf2/fission-reread.exp) that in
	fill_in_sig_entry_from_dwo_entry, the m_length field is overwritten.
	For now, allow for that exception.

	While we're at it, make sure that the length is set before read.

	Tested on x86_64-linux.

	gas: tc-tic54x.c hash tables
	Cleaning up the subsym_hash memory is a real pain.  Keys and values
	entered into the table are quite diverse.  In some cases the key is
	allocated and thus needs to be freed, in others the key is a const
	string.  Values are similar, and in some cases not even a string.
	Tidy this by inserting a new subsym_ent_t that describes key/value
	type.  This meant the math_hash table was no longer needed.  The patch
	also tidies how math functions are called, those that are supposed to
	return int now no longer return their value in a float.

	gas: use notes_calloc in string hash
	Using notes_calloc means all of the string hash table memory should
	now be freed before gas exits, even though htab_delete isn't called.
	This also means that the hash table free_f and del_f must be NULL,
	because freeing notes obstack memory results in all more recently
	allocated notes memory being freed too.  So hash table resizing won't
	free any memory, and will be a little faster.  Also, htab_delete won't
	do anything (and be quick about it).

	Since htab_traverse can also resize hash tables (to make another
	traversal faster if the table is largely empty), stop that happening
	when only one traversal is done.

		* as.h: Reorder hash.h after symbols.h for notes_calloc decl.

	i386 gas: don't leak op_hash or reg_hash memory
	This tidies memory used by the two x86 gas string hash tables before

	core_optab memory on the notes obstack.  It would be possible to free
	core_optab memory by using a custom hash table del_f on x86, as I do

	gas: rename md_end to md_finish
	Currently md_end is typically used for some final actions rather than
	freeing memory like other *_end functions.  Rename it to md_finish,
	and rename target implementation.  The renaming of target functions
	makes it possible to find them all with "grep md_finish",
	eg. md_mips_end is renamed to mips_md_finish, not md_mips_finish.
	This patch leaves a number of md_end functions unchanged, those that
	either do nothing or deallocate memory, and calls them late.

	The idea here is that target maintainers implement md_end functions to
	tidy memory, if anyone cares.  Freeing persistent memory in gas is
	not at all important, except that it can hide more important memory
	leaks, those that happen once per some frequent gas operation, amongst
	these unimportant memory leaks.

	Regenerate with automake-1.15.1

	Fix this by disabling the specific deprecation warning.

	Also handle upcoming guile versions > 3.0, in which the variable will be
	removed, by limiting the usage of the variable to guile versions <= 3.0.

	This does not break anything.  The variable was merely used to address a
	problem present in guile versions <= v3.0.5.

	Note that we don't limit the usage of the variable to guile versions <= 3.0.5,
	because we want to support f.i. building against 3.0.6 and then using a shared
	lib with 3.0.5.

	Tested on x86_64-linux.

	libopcodes/s390: add support for disassembler styling
	This commit adds disassembler style to the libopcodes s390
	disassembler.  This conversion was pretty straight forward, I just
	converted the fprintf_func calls to fprintf_styled_func calls and
	added an appropriate style.

	For testing the new styling I just assembled then disassembled the
	source files in gas/testsuite/gas/s390 and manually checked that the
	styling looked reasonable.

	If the user does not request styled output from objdump, then there
	should be no change in the disassembler output after this commit.

	    ---------------------
	    ../../src/binutils-gdb/gdb/inferior.c:304: internal-error: find_inferior_pid: Assertion `pid != 0' failed.
	    A problem internal to GDB has been detected,
	    further debugging may prove unreliable.
	    Quit this debugging session? (y or n)

	This is due to some bit-rot in the AIX port, still relying on the entry
	value of inferior_ptid in the wait methods.

	Problem #1 is in rs6000_nat_target::wait, here:

	      /* Ignore terminated detached child processes.  */
	      if (!WIFSTOPPED (status) && pid != inferior_ptid.pid ())
		pid = -1;

	At this point, waitpid has returned an "exited" status for some pid, so
	pid is non-zero.  Since inferior_ptid is set to null_ptid on entry, the
	pid returned by wait is not equal to `inferior_ptid.pid ()`, so we reset
	pid to -1 and go to waiting again.  Since there are not more children to
	wait for, waitpid then returns -1 so we get here:

	      if (pid == -1)
		{
		  gdb_printf (gdb_stderr,
			      _("Child process unexpectedly missing: %s.\n"),
			      safe_strerror (save_errno));

		  /* Claim it exited with unknown signal.  */
		  ourstatus->set_signalled (GDB_SIGNAL_UNKNOWN);
		  return inferior_ptid;
		}

	We therefore return a "signalled" status with a null_ptid (again,
	inferior_ptid is null_ptid).  This confuses infrun, because if the
	target returns a "signalled" status, it should be coupled with a ptid
	for an inferior that exists.

	So, the first step is to fix the snippets above to not use
	inferior_ptid.  In the first snippet, use find_inferior_pid to see if
	we know the event process.  If there is no inferior with that pid, we
	assume it's a detached child process to we ignore the event.  That
	should be enough to fix the problem, because it should make it so we
	won't go into the second snippet.  But still, fix the second snippet to
	return an "ignore" status.  This is copied from inf_ptrace_target::wait,
	which is where rs6000_nat_target::wait appears to be copied from in the
	first place.

	These changes, are not sufficient, as the aix_thread_target, which sits
	on top of rs6000_nat_target, also relies on inferior_ptid.
	aix_thread_target::wait, by calling pd_update, assumes that
	rs6000_nat_target has set inferior_ptid to the appropriate value (the
	ptid of the event thread), but that's not the case.  pd_update
	returns inferior_ptid - null_ptid - and therefore
	aix_thread_target::wait returns null_ptid too, and we still hit the
	assert shown above.

	Fix this by changing pd_activate, pd_update, sync_threadlists and
	get_signaled_thread to all avoid using inferior_ptid.  Instead, they
	accept as a parameter the pid of the process we are working on.

	With this patch, I am able to run the program to completion:

	    (gdb) r
	    Starting program: /scratch/simark/build/gdb/a.out
	    [Inferior 1 (process 11010794) exited normally]

	As well as break on main:

	    Breakpoint 1 at 0x1000036c
	    (gdb) r
	    Starting program: /scratch/simark/build/gdb/a.out

	    Breakpoint 1, 0x1000036c in main ()
	    (gdb) c
	    Continuing.
	    [Inferior 1 (process 26083688) exited normally]

2022-07-07  Pedro Alves  <pedro@palves.net>

	Fix pedantically invalid DWARF in gdb.trace/unavailable-dwarf-piece.exp
	The DWARF spec says:

	  Any debugging information entry representing the declaration of an object,
	  module, subprogram or type may have DW_AT_decl_file, DW_AT_decl_line and
	  DW_AT_decl_column attributes, each of whose value is an unsigned integer
								  ^^^^^^^^
	  constant.

	Grepping around the DWARF-assembler-based testcases, I noticed that
	gdb.trace/unavailable-dwarf-piece.exp emits decl_line with
	DW_FORM_sdata, a signed integer form.  This commit tweaks it to use
	DW_FORM_udata instead.

	Unsurprisingly, this:

	  $ make check \
	      TESTS="gdb.trace/unavailable-dwarf-piece.exp" \
	      RUNTESTFLAGS="--target_board=native-gdbserver"

	... still passes cleanly for me after this change.

	I've noticed this because current llvm-dwarfdump crashed on an
	ROCm-internal DWARF-assembler-based testcase that incorrectly used
	signed forms for DW_AT_decl_file/DW_AT_decl_line.

	The older llvm-dwarfdump found on Ubuntu 20.04 (LLVM 10) reads the
	line numbers with signed forms as "0" instead of crashing.  Here's the
	before/after fix for gdb.trace/unavailable-dwarf-piece.exp with that
	llvm-dwarfdump version:

	x86: make D attribute usable for XOP and FMA4 insns
	This once again allows to reduce redundancy in (and size of) the opcode
	table.

	Don't go as far as also making D work on the two 5-operand XOP insns:
	This would significantly complicate the code, as there the first
	(immediate) operand would need special treatment in several places.

	Note that the .s suffix isn't being enabled to have any effect, for
	being deprecated. Whereas neither {load} nor {store} pseudo prefixes
	make sense here, as the respective operands are inputs (loads) only
	anyway, regardless of order. Hence there is (as before) no way for the
	programmer to request the alternative encoding to be used for register-
	only insns.

	Note further that it is always the first original template which is
	retained (and altered), to make sure the same encoding as before is
	used for register-only insns. This has the slightly odd (but pre-
	existing) effect of XOP register-only insns having XOP.W clear, but FMA4
	ones having VEX.W set.

	causing an internal error. Alongside dealing with this also drop a
	related comment, which hasn't been applicable anymore since the
	introduction of 3-operand patterns with D set (and which perhaps never
	had been logical to be there, as reverse-matched insns don't make it
	there in the first place).

	perhaps many "negative" ones. Like some other architectures allow
	saving (pushing) and restoring (popping) present/prior state.

	For now require the same .code<N> to be in effect for ".arch pop" that
	was in effect for the corresponding ".arch push".

	gdb: LoongArch: add orig_a0 into register set
	The basic support for LoongArch has been merged into the upstream Linux
	kernel since 5.19-rc1 on June 5, 2022.  This commit adds orig_a0 which
	is added into struct user_pt_regs [1] to match the upstream kernel, and
	then the upstream GDB will work with the upstream kernel.

	Note that orig_a0 was added into struct user_pt_regs in the development
	cycle for merging LoongArch port into the upstream Linux kernel, so
	earlier kernels (notably, the product kernel with version 4.19 used in
	distros like UOS and Loongnix) don't have it.  Inspect
	arch/loongarch/include/uapi/asm/ptrace.h in the kernel tree to make sure.
	To build upstream GDB for a kernel lacking orig_a0, it's necessary to
	revert this commit locally.

	x86: fold Disp32S and Disp32
	The only case where 64-bit code uses non-sign-extended (can also be
	considered zero-extended) displacements is when an address size override
	is in place for a memory operand (i.e. particularly excluding
	displacements of direct branches, which - if at all - are controlled by
	operand size, and then are still sign-extended, just from 16 bits).
	Hence the distinction in templates is unnecessary, allowing code to be
	simplified in a number of places. The only place where logic becomes
	more complicated is when signed-ness of relocations is determined in
	output_disp().

	The other caveat is that Disp64 cannot be specified anymore in an insn
	template at the same time as Disp32. Unlike for non-64-bit mode,
	templates don't specify displacements for both possible addressing
	modes; the necessary adjustment to the expected ones has already been
	done in match_template() anyway (but of course the logic there needs
	tweaking now). Hence the single template so far doing so is split.

	x86: restore masking of displacement kinds
	Commit 7d5e4556a375 rendered the check near the end of what is now
	i386_finalize_displacement() entirely dead for AT&T mode, since for
	operands involving a displacement .unspecified will always be set. But
	the logic there is bogus anyway - Intel syntax operand size specifiers
	are of no interest there either. The only thing which matters in the
	"displacement only" determination is .baseindex.

	Of course when masking displacement kinds we should not at the same time
	also mask off other attributes.

	Furthermore the type mask returned by lex_got() also needs to be
	adjusted: The only case where we want Disp32 (rather than Disp32S) is
	when dealing with 32-bit addressing mode in 64-bit code.

	When building gdb with -fsanitize=thread and gcc 12, and running test-case

	Fix this by setting the field earlier, in read_comp_units_from_section.

	The write in cutu_reader::cutu_reader() is still needed, in case
	read_comp_units_from_section is not used (run the test-case with say, target
	board cc-with-gdb-index).

	Make the write conditional, such that it doesn't trigger if the field is
	already set by read_comp_units_from_section.  Instead, verify that the
	field already has the value that we're trying to set it to.

	Move this logic into into a member function set_version (in analogy to the
	already present member function version) to make sure it's used consistenly,
	and make the field private in order to enforce access through the member
	functions, and rename it to m_dwarf_version.

	While we're at it, make sure that the version is set before read, to avoid
	say returning true for "per_cu.version () < 5" if "per_cu.version () == 0".

	GDB: Add `NUMBER' completion to `set' integer commands
	Fix a completion consistency issue with `set' commands accepting integer
	values and the special `unlimited' keyword:

	(gdb) complete print -elements
	print -elements NUMBER
	print -elements unlimited
	(gdb)

	vs:

	(gdb) complete set print elements
	set print elements unlimited
	(gdb)

	(there is a space entered at the end of both commands, not shown here)
	which also means if you strike <Tab> with `set print elements ' input,
	it will, annoyingly, complete to `set print elements unlimited' right
	away rather than showing a choice between `NUMBER' and `unlimited'.

	Add `NUMBER' then as an available completion for such `set' commands:

	(gdb) complete set print elements
	set print elements NUMBER
	set print elements unlimited
	(gdb)

	Adjust the testsuite accordingly.  Also document the feature in the
	Completion section of the manual in addition to the Command Options
	section already there.

	Above we see that in the non-existing-program case, the process gets
	deleted before the starting_up flag gets restored to false.

	This happens because startup_inferior calls target_mourn_inferior
	before throwing an error, and in GDBserver, unlike in GDB, mourning
	deletes the process.

	Fix this by not using a scoped_restore to manage the starting_up flag,
	since we should only clear it when startup_inferior doesn't throw.

	opcodes/aarch64: split off creation of comment text in disassembler
	The function aarch64_print_operand (aarch64-opc.c) is responsible for
	converting an instruction operand into the textual representation of
	that operand.

	In some cases, a comment is included in the operand representation,
	though this (currently) only happens for the last operand of the
	instruction.

	In a future commit I would like to enable the new libopcodes styling
	for AArch64, this will allow objdump and GDB[1] to syntax highlight
	the disassembler output, however, having operands and comments
	combined in a single string like this makes such styling harder.

	In this commit, I propose to extend aarch64_print_operand to take a
	second buffer.  Any comments for the instruction are written into this
	extra buffer.  The two callers of aarch64_print_operand are then
	updated to pass an extra buffer, and print any resulting comment.

	In this commit no styling is added, that will come later.  However, I
	have adjusted the output slightly.  Before this commit some comments
	would be separated from the instruction operands with a tab character,
	while in other cases the comment was separated with two single spaces.

	After this commit I use a single tab character in all cases.  This
	means a few test cases needed updated.  If people would prefer me to
	move everyone to use the two spaces, then just let me know.  Or maybe
	there was a good reason why we used a mix of styles, I could probably
	figure out a way to maintain the old output exactly if that is
	critical.

	Other than that, there should be no user visible changes after this
	commit.

	gdb/testsuite: fix gdb.base/break-idempotent.exp on ppc
	When running the gdb.base/break-idempotent.exp test on ppc, I was
	seeing some test failures (or rather errors), that looked like this:

	  (gdb) watch local
	  Hardware watchpoint 2: local

	  has_hw_wp_support: Hardware watchpoint detected
	  ERROR: no fileid for gcc2-power8
	  ERROR: Couldn't send delete breakpoints to GDB.
	  ERROR OCCURED: can't read "gdb_spawn_id": no such variable
	      while executing
	  "expect {
	  -i 1000 -timeout 100
	          -re ".*A problem internal to GDB has been detected" {
	              fail "$message (GDB internal error)"
	              gdb_internal_erro..."
	      ("uplevel" body line 1)
	      invoked from within

	What happens is that in break-idempotent.exp we basically do this:

	    if {[prepare_for_testing "failed to prepare" $binfile $srcfile $opts]} {
	        continue
	    }

	    # ....

	    if {![skip_hw_watchpoint_tests]} {
	        test_break $always_inserted "watch"
	    }

	The problem with this is that skip_hw_watchpoint_tests, includes this:

	    if { [istarget "i?86-*-*"]
		 || [istarget "x86_64-*-*"]
		 || [istarget "ia64-*-*"]
		 || [istarget "arm*-*-*"]
		 || [istarget "aarch64*-*-*"]
		 || ([istarget "powerpc*-*-linux*"] && [has_hw_wp_support])
		 || [istarget "s390*-*-*"] } {
		return 0
	    }

	For powerpc only we call has_hw_wp_support.  This is a caching proc
	that runs a test within GDB to detect if we have hardware watchpoint
	support or not.

	Unfortunately, to run this test we restart GDB, and when the test has
	completed, we exit GDB.  This means that in break-idempotent.exp, when
	we call skip_hw_watchpoint_tests for the first time on powerpc, GDB
	will unexpectedly be exited.  When we later call delete_breakpoints we
	see the errors I reported above.

	The fix is to call skip_hw_watchpoint_tests early, before we start GDB
	as part of the break-idempotent.exp script, and store the result in a
	variable, we can then check this variable in the script as needed.

	After this change break-idempotent.exp runs fine on powerpc.

	gdb+gdbserver/Linux: avoid reading registers while going through shell
	For every stop, Linux GDB and GDBserver save the stopped thread's PC,
	in lwp->stop_pc.  This is done in save_stop_reason, in both
	gdb/linux-nat.c and gdbserver/linux-low.cc.  However, while we're
	going through the shell after "run", in startup_inferior, we shouldn't
	be reading registers, as we haven't yet determined the target's
	architecture -- the shell's architecture may not even be the same as
	the final inferior's.

	In gdb/linux-nat.c, lwp->stop_pc is only needed when the thread has
	stopped for a breakpoint, and since when going through the shell, no
	breakpoint is going to hit, we could simply teach save_stop_reason to
	only record the stop pc when the thread stopped for a breakpoint.

	However, in gdbserver/linux-low.cc, lwp->stop_pc is used in more cases
	than breakpoint hits (e.g., it's used in tracepoints & the
	"while-stepping" feature).

	So to avoid GDB vs GDBserver divergence, we apply the same approach to
	both implementations.

	We set a flag in the inferior (process in GDBserver) whenever it is
	being nursed through the shell, and when that flag is set,
	save_stop_reason bails out early.  While going through the shell,
	we'll only ever get process exits (normal or signalled), random
	signals, and exec events, so nothing is lost.

	gdb:csky add pseudo regs for float and vector regs
	In the existing CSKY architecture, there are at most 32 floating
	and 16 vector registers. Float registers's count can be configured
	as 16 or 32. In the future, the vector registers's count may be
	extended to 32.

	The bit width of floating-point register is 64bits, and the bit
	width of vector register is 128bit.

	Special points: in fr0~fr15 and vr0~vr15, each FRx is the lower
	64 bits of the corresponding VRx.

	Here, we will split each floating-point and vector register to
	32bits wide, add the corresponding pseudo registers, and finally
	use them for the dwarf registers.

	There are 128 pseudo registers in total, s0~s127, including:
	1. s0 and s1 correspond to fr0, s4 and s5 correspond to fr1, and so on.
	Every two separated pseudo registers correspond to a float register.
	2. s0, s1, s2 and s3 correspond to vr0; s4, s5, s6 and s7 correspond to vr1,
	and so on. Every four pseudo registers corresponds to a vector register.

	Therefore, in s64~s127, there are general registers that are not actually
	used. This part is to prepare for the expansion of vector registers to 32

	Therefore, in s64~s127, half of the registers are actually unused. This
	part is to prepare for the expansion of the vector register to 32.

	Make GDBserver abort on internal error in development mode
	Currently, if GDBserver hits some internal assertion, it exits with
	error status, instead of aborting.  This makes it harder to debug
	GDBserver, as you can't just debug a core file if GDBserver fails an
	assertion.  I've had to hack the code to make GDBserver abort to debug
	something several times before.

	I believe the reason it exits instead of aborting, is to prevent
	potentially littering the filesystem of smaller embedded targets with
	core files.  I think I recall Daniel Jacobowitz once saying that many
	years ago, but I can't be sure.  Anyhow, that seems reasonable to me.

	Since we nowadays have a distinction between development and release
	modes, I propose to make GDBserver abort on internal error if in
	development mode, while keeping the status quo when in release mode.

	Thus, after this patch, in development mode, you get:

	 $ ../gdbserver/gdbserver
	 ../../src/gdbserver/server.cc:3711: A problem internal to GDBserver has been detected.
	 captured_main: Assertion `0' failed.
	 Aborted (core dumped)
	 $

	while in release mode, you'll continue to get:

	 $ ../gdbserver/gdbserver
	 ../../src/gdbserver/server.cc:3711: A problem internal to GDBserver has been detected.
	 captured_main: Assertion `0' failed.
	 $ echo $?
	 1

	I do not think that this requires a separate configure switch.

	A "--target_board=native-extended-gdbserver" run on Ubuntu 20.04 ends
	up with:

			 === gdb Summary ===

	 # of unexpected core files      29
	 ...

	for me, of which 8 are GDBserver core dumps, 7 more than without this
	patch.

	[gdb/symtab] Fix parsing of .debug_str_offsets header
	When running test-case gdb.dwarf2/fission-mix.exp with target board dwarf64
	and gcc-12 (defaulting to DWARF5), I run into:
	...
	(gdb) break func2^M
	Offset from DW_FORM_GNU_str_index or DW_FORM_strx pointing outside of \
	  .debug_str.dwo section in CU at offset 0x0 [in module fission-mix]^M
	(gdb) FAIL: gdb.dwarf2/fission-mix.exp: break func2
	...

	The .debug_str_offsets section has version 5, so as per the standard it has
	it's own header, with initial length and version:
	...
	Contents of the .debug_str_offsets.dwo section (loaded from fission-mix2.dwo):

	    Length: 0x1c
	    Version: 0x5
	       Index   Offset [String]
	           0        0 build/gdb/testsuite
	           1       33 GNU C17
	           2       8f src/gdb/testsuite/gdb.dwarf2/fission-mix-2.c
	...

	But when trying to read the string offset at index 0 in the table (which
	is 0), we start reading at offset 8, which points in the header, at the last
	4 bytes of the initial length (it's 12 bytes because of 64-bit dwarf), as well
	at the 2-byte version field and 2 bytes of padding, so we get:
	...
	(gdb) p /x str_offset
	$1 = 0x500000000
	...
	which indeed is an offset that doesn't fit in the .debug_str section.

	The offset 8 is based on reader->cu->header.addr_size:
	...
	static const char *
	read_dwo_str_index (const struct die_reader_specs *reader, ULONGEST str_index)
	{
	 ULONGEST str_offsets_base = reader->cu->header.version >= 5
	                             ? reader->cu->header.addr_size : 0;
	...
	which doesn't in look in agreement with the standard.

	Note that this happens to give the right answer for 32-bit dwarf and
	addr_size == 8, because then we have header size ==
	(initial length (4) + version (2) + padding (2)) == 8.

	Conversely, for 32-bit dwarf and addr_size == 4 (target board unix/-m32)
	we run into a similar problem.  It just happens to not trigger the warning,
	instead we get the wrong strings, like "func2" for DW_AT_producer and
	"build/gdb/testsuite" for DW_AT_name of the DW_TAG_compile_unit DIE.

	Fix this by parsing the .debug_str_offsets header in read_dwo_str_index.

	Add a FIXME that we should not parse this for every call.

	Tested on x86_64-linux.

	which looks similar to what is described in commit 78e49486944 ("[gdb/build]
	Fix gdbserver build with -fsanitize=address").

	The gdbserver component builds a shared library libinproctrace.so, which uses
	libiberty and therefore requires the pic variant.  The gdbserver Makefile is
	setup to use this variant, if available, but it's not there.

	Fix this by listing gdbserver in the toplevel configure alongside libcc1, as a

	because changes in offset to PLT entries might mean a change in stub
	sizes.  When -z relro, the relro layout does this by laying out
	sections from the end of the relro segment.  So for example, a change
	in .eh_frame (which happens after stub sizing) will keep the same GOT
	to PLT offset when -z relro.  Not so when -z norelro, because then the
	usual forward layout of section is done and .got is more aligned than
	.branch_lt.

		* emulparams/elf64ppc.sh: Set .branch_lt address fixed relative
		to .got.
		* testsuite/ld-powerpc/elfv2exe.d: Adjust to suit.

	-z relro relaxation and ld script SIZEOF
	A number of targets use assignments like:
	. = DATA_SEGMENT_RELRO_END (SIZEOF (.got.plt) >= 12 ? 12 : 0, .);
	(from i386) in linker scripts to put the end of the relro segment past
	the header in .got.plt.  Examination of testcases like those edited by
	this patch instead sees the end of the relro segment being placed at
	the start of .got.plt.  For the i386 pie1 test:

	Fix corrupt DWARF in dw2-double-set-die-type
	The dw2-double-set-die-type.exp test case caused an AddressSanitizer
	failure in the new DWARF scanner.

	The immediate cause was bad DWARF in the test -- in particular, the
	the sibling attribute here:

	     <2><181>: Abbrev Number: 33 (DW_TAG_subprogram)
		<182>   DW_AT_external    : 1
		<183>   DW_AT_name        : address
		<18b>   DW_AT_type        : <0x171>
		<18f>   DW_AT_declaration : 1
		<190>   DW_AT_sibling     : <0x1a1>
	    ...
	     <1><1a1>: Abbrev Number: 23 (DW_TAG_pointer_type)
		<1a2>   DW_AT_byte_size   : 4
		<1a3>   DW_AT_type        : <0x1a7>

	...points to a "sibling" DIE that is at a different child depth.

	Because this test case doesn't really require sibling attributes, this
	patch fixes the problem by removing them from the test.

	Note that gdb is not generally robust against malformed DWARF.
	Detecting and compensating for this problem would probably be
	expensive and, IMO, is better left to some (still hypothetical) DWARF
	linter.

	Eliminate TUI/CLI observers duplication
	For historical reasons, the CLI and the TUI observers are basically
	exact duplicates, except for the downcast:

	 cli:
	       struct cli_interp *cli = as_cli_interp (interp);
	 tui:
	       struct interp *tui = as_tui_interp (interp);

	and how they get at the interpreter's ui_out:

	 cli:
	       cli->cli_uiout
	 tui:
	       tui->interp_ui_out ()

	Since interp_ui_out() is a virtual method that also works for the CLI
	interpreter, and, both the CLI and the TUI interpreters inherit from
	the same base class (cli_interp_base), we can convert the CLI
	observers to cast to cli_interp_base instead and use interp_ui_out()
	too.  With that, the CLI observers will work for the TUI interpreter
	as well.  This lets us completely eliminate the TUI observers.  That's
	what this commit does.

	gdb/testsuite: remove unneeded calls to get_compiler_info
	It is not necessary to call get_compiler_info before calling
	test_compiler_info, and, after recent commits that removed setting up
	the gcc_compiled, true, and false globals from get_compiler_info,
	there is now no longer any need for any test script to call
	get_compiler_info directly.

	As a result every call to get_compiler_info outside of lib/gdb.exp is
	redundant, and this commit removes them all.

	There should be no change in what is tested after this commit.

2022-06-24  Andrew Burgess  <aburgess@redhat.com>

	gdb/testsuite: remove global gcc_compiled from gdb.exp
	After this commit the gcc_compiled global is no longer exported from
	lib/gdb.exp.  In theory we could switch over all uses of gcc_compiled
	to instead call test_compiler_info directly, however, I have instead
	added a new proc to gdb.exp: 'is_c_compiler_gcc'.  I've then updated
	the testsuite to call this proc instead of using the global.

	Having a new proc specifically for this task means that we have a
	single consistent pattern for detecting gcc.  By wrapping this logic
	within a proc that calls test_compiler_info, rather than using the
	global, means that test scripts don't need to call get_compiler_info
	before they read the global, simply calling the new proc does
	everything in one go.

	As a result I've been able to remove the get_compiler_info calls from
	all the test scripts that I've touched in this commit.

	In some of the tests e.g. gdb.dwarf2/*.exp, the $gcc_compiled flag was
	being checked at the top of the script to decide if the whole script
	should be skipped or not.  In these cases I've called the new proc
	directly and removed all uses of gcc_compiled.

	In other cases, e.g. most of the gdb.base scripts, there were many
	uses of gcc_compiled.  In these cases I set a new global gcc_compiled
	near the top of the script, and leave the rest of the script
	unchanged.

	There should be no changes in what is tested after this commit.

	Include count of unexpected core files in gdb.sum summary
	If GDB, GDBserver, a testcase program, Valgrind, etc. unexpectedly
	crash while running the GDB testsuite, and you've setup your machine
	such that core files are dumped in the current directory instead of
	being shoved somewhere by abrt, apport, or similar (as you should for
	proper GDB testing), you'll end up with an unexpected core file in the
	$build/gdb/testsuite/ directory.

	It can happen that GDB, GDBserver, etc. even crashes _after_ gdb_exit,
	during teardown, and thus such a crash won't be noticed by looking at
	the gdb.sum file at all.  This commit aims at improving that, by
	including a new "unexpected core files" line in the testrun summary.

	For example, here's what I get on x86-64 Ubuntu 20.04, with this
	patch:

			 === gdb Summary ===

	 # of unexpected core files      12          << new info
	 # of expected passes            107557
	 # of unexpected failures        35
	 # of expected failures          77
	 # of unknown successes          2
	 # of known failures             114
	 # of untested testcases         31
	 # of unsupported tests          139

	I have my core pattern setup like this:

	 $ cat /proc/sys/kernel/core_pattern
	 core.%e.%p.%h.%t

	That's:

	 %e: executable filename
	 %p: pid
	 %h: hostname
	 %t: UNIX time of dump

	and so I get these core files:

	 $ ls -1 testsuite/core.*
	 testsuite/core.connect-with-no.216191.nelson.1656002431
	 testsuite/core.connect-with-no.217729.nelson.1656002431
	 testsuite/core.gdb.194247.nelson.1656002423
	 testsuite/core.gdb.226014.nelson.1656002435
	 testsuite/core.gdb.232078.nelson.1656002438
	 testsuite/core.gdb.352268.nelson.1656002441
	 testsuite/core.gdb.4152093.nelson.1656002337
	 testsuite/core.gdb.4154515.nelson.1656002338
	 testsuite/core.gdb.4156668.nelson.1656002339
	 testsuite/core.gdb.4158871.nelson.1656002341
	 testsuite/core.gdb.468495.nelson.1656002444
	 testsuite/core.vgdb.4192247.nelson.1656002366

	where we can see that GDB crashed a number of times, but also
	Valgrind's vgdb, and a couple testcase programs.  Neither of which is
	good.

	If your core_pattern is just "core" (but why??), then I guess that you
	may end up with just a single core file in testsuite/.  Still, that is
	one core file too many.

	Above, we see a couple cores for "connect-with-no", which are the
	result of gdb.server/connect-with-no-symbol-file.exp.  This is a case
	mentioned above -- while the program crashed, that happens during
	testcase teardown, and it goes unnoticed (without this commit) by
	gdb.sum results.  Vis:

	 $ make check TESTS="gdb.server/connect-with-no-symbol-file.exp"
	 ...
			 === gdb Summary ===

	 # of unexpected core files      2
	 # of expected passes            8

	 ...
	 $

	The tests fully passed, but still the testcase program crashed
	somehow:

	 $ ls -1 testsuite/core.*
	 testsuite/core.connect-with-no.941561.nelson.1656003317
	 testsuite/core.connect-with-no.941682.nelson.1656003317

	Against --target_board=native-extended-gdbserver it's even worse.  I
	get:

	 # of unexpected core files      26

	and note that when GDBserver hits an assertion failure, it exits with
	error, instead of crashing with SIGABRT.  I think that should be
	changed, at least on development builds, but that would be for another
	patch.  After such patch, I suspect the number of unexpected cores
	will be higher, as there are likely teardown GDBserver assertions that
	we're not noticing.

	I decided to put this new info in the "gdb Summary" section, as that's
	a place people already are used to looking at, either when looking at
	the tail of gdb.sum, or when diffing gdb.sum files, and we've already
	extended this section before, to include the count of DUPLICATE and
	PATH problems, so there's precedent.

	Implementation-wise, the new line is appended after DejaGnu is
	finished, with a shell script that is invoked by the Makefile.  It is
	done this way so that serial and parallel testing work the same way.
	My initial cut at an implementation was in TCL, straight in
	testsuite/lib/check-test-names.exp, where DUPLICATES and PATH are
	handled, like so:

	 @@ -148,6 +159,10 @@ namespace eval ::CheckTestNames {
		     $counts(paths,$which)
		 maybe_show_count "# of duplicate test names\t" \
		     $counts(duplicates,$which)
	 +
	 +       set cores [glob -nocomplain -directory $::objdir core*]
	 +       maybe_show_count "# of unexpected core files\t" \
	 +           [llength $cores]
	      }

	But that would only work for serial testing, as in parallel testing,
	the final gdb.sum is generated by aggregating the results of all the
	individual gdb.sum files, and dg-extract-results.sh doesn't know about
	our new summary line.  And I don't think that dg-extract-results.sh
	should be taught about it, since the count of core files is not
	something that we want to count many times, once per testcase, and
	then add up the subcounts at the end.  Every time we count the core
	files, we're already counting the final count.

	I considered using the Tcl implementation in serial mode, and the
	script approach for parallel testing, but that has the obvious
	downside of implementing and maintaining the same thing twice.  In the
	end, I settled on the script approach for serial mode too, which
	requires making the "check-single" rule print the tail end of the
	gdb.sum file, with a side effect being that if you look at the
	terminal after a run (instead of at the gdb.sum file), you'll see the
	"gdb Summary" section twice, once without the unexpected core lines
	printed, and then another with.  IMO, this isn't an issue; when
	testing in parallel mode, if you look at the terminal after "make -jN
	check", you'll also see multiple "gdb Summary" sections printed.

	Improve core file path detection & put cores in output dir
	After a testrun, I noticed that I have some kernel-produced cores for
	testcase programs, under build/gdb/testsuite/, which shouldn't be
	there:

	 $ ls -1 testsuite/core.*
	 testsuite/core.annota1.1274351.nelson.1656004407
	 testsuite/core.annota3.1288474.nelson.1656004414
	 testsuite/core.exitsignal.1240674.nelson.1656004391

	I have my core pattern setup like this:

	 $ cat /proc/sys/kernel/core_pattern
	 core.%e.%p.%h.%t

	That's:

	 %e: executable filename
	 %p: pid
	 %h: hostname
	 %t: UNIX time of dump

	so it's easy to tell which program produced the core from the core
	file name.

	From above, we can tell that the corresponding testcases are
	gdb.base/annota1.exp, gdb.base/annota3.exp and
	gdb.base/exitsignal.exp.

	At least gdb.base/annota1.exp and gdb.base/annota3.exp have code in
	them to delete the core file.  However, that isn't working for me,
	because said code only looks for cores named exactly either "core" or
	"core.PID", and my core_pattern doesn't match that.

	Another issue I noticed, is that I have not been running
	gdb.base/bigcore.exp, for a similar reason.  I get:

	  Program terminated with signal SIGABRT, Aborted.
	  The program no longer exists.
	  (gdb) PASS: gdb.base/bigcore.exp: signal SIGABRT
	  UNTESTED: gdb.base/bigcore.exp: can't generate a core file

	But I actually have a core file under the testcase's output dir:

	 $ find . -name "core.*"
	 ./testsuite/outputs/gdb.base/bigcore/core.bigcore.2306705.nelson.1656005213
	 $

	This commit fixes these things, by adding a find_core_file routine
	that searches core files in a way that works with my core pattern as
	well.  This then also adds a convenience remove_core routine as a
	wrapper around find_core_file that removes the found core file.

	In addition, it changes some testcases that expect to have their
	program dump core, to switch the inferior's cwd to the testcase's
	output dir, so that the core is dumped there instead of in
	build/gdb/testsuite/.  Some testcases were already doing that, but not
	all.  The idea is that any core file dumped in build/gdb/testsuite/ is
	an unexpected core file.  The next patch will add a count of such
	unexpected core files to gdb.sum.

	Another change is that the directory changing is now done with "set
	cwd" instead of with "cd".  "set cwd" only affects the inferior cwd,
	while "cd" affects GDB's cwd too.  By using "set cwd" instead of "cd",
	if GDB dumps core in these testcases, the GDB core dump will still end
	up in build/gdb/testsuite/, and can thus be detected as an unexpected
	core.

	gdb: make use of RAII in run_inferior_call
	In passing I noticed that there are three local variables in
	run_inferior_call that are used to save, and then restore some state,
	I think these could all be replaced with a RAII style scoped_restore
	instead.

	Of the three locals that I've changed, the only one that I believe is
	now restored in a different location is ui::async, before this commit
	the async field was restored after a call to either delete_file_handle
	or ui_register_input_event_handler, and after this commit, the field
	is restored before these calls.  However, I don't believe that either
	of these functions depend on the value of the async field, so I
	believe the commit is fine.

	aarch64: Define elf_backend_extern_protected_data to 0 [PR 18705]
	Follow-up to commit 90b7a5df152a64d2bea20beb438e8b81049a5c30
	("aarch64: Disallow copy relocations on protected data").

	Commit 32f573bcb3aaa1c9defcad79dbb5851fcc02ae2d changed ld to produce
	R_AARCH64_GLOB_DAT but that defeated the purpose of protected visibility
	as an optimization.  Restore the previous behavior (which matches
	ld.lld) by defining elf_backend_extern_protected_data to 0.

	Use std::string for interpreter_p
	The global interpreter_p is a manually-managed 'char *'.  This patch
	changes it to be a std::string instead, and removes some erroneous
	comments.

	Move mi_interpreter to mi-interp.h
	I noticed that touching interps.h caused a lot of recompilation.  I
	tracked this down to mi-common.h including this file.  This patch
	moves the MI interpreter to mi-interp.h, which cuts down on
	recompilation when modifying interps.h.

	Use unique_xmalloc_ptr in interp
	This changes interp::m_name to be a unique_xmalloc_ptr, removing some
	manual memory management.  It also cleans up the initialization of the
	'inited' member, and moves the 'private:' and 'public:' keywords to
	their proper spots.

	aarch64: Disallow copy relocations on protected data
	If an executable has copy relocations for extern protected data, that
	can only work if the shared object containing the definition is built
	with assumptions (a) the compiler emits GOT-generating relocations (b)
	the linker produces R_*_GLOB_DAT instead of R_*_RELATIVE.  Otherwise the
	shared object uses its own definition directly and the executable
	accesses a stale copy.  Note: the GOT relocations defeat the purpose of
	protected visibility as an optimization, and it turns out this never
	worked perfectly.

	glibc 2.36 will warn on copy relocations on protected data.  Let's
	produce a warning at link time, matching ld.lld which has been used on
	many aarch64 OSes.

	Note: x86 requires GNU_PROPERTY_NO_COPY_ON_PROTECTED to have the error.
	This is to largely due to GCC 5's "x86-64: Optimize access to globals in
	PIE with copy reloc" which started to use direct access relocations for
	external data symbols in -fpie mode.

	GCC's aarch64 port does not have the change.  Nowadays with most builds
	switching to -fpie/-fpic, aarch64 mostly doesn't need to worry about
	copy relocations.  So for aarch64 we simply don't check
	GNU_PROPERTY_NO_COPY_ON_PROTECTED.

	libctf: fix linking together multiple objects derived from the same source
	Right now, if you compile the same .c input repeatedly with CTF enabled
	and different compilation flags, then arrange to link all of these
	together, then things misbehave in various ways.  libctf may conflate
	either inputs (if the .o files have the same name, say if they are
	stored in different .a archives), or per-CU outputs when conflicting
	types are found: the latter can lead to entirely spurious errors when
	it tries to produce multiple per-CU outputs with the same name
	(discarding all but the last, but then looking for types in the earlier
	ones which have just been thrown away).

	Fixing this is multi-pronged.  Both inputs and outputs need to be
	differentiated in the hashtables libctf keeps them in: inputs with the
	same cuname and filename need to be considered distinct as long as they
	have different associated CTF dicts, and per-CU outputs need to be
	considered distinct as long as they have different associated input
	dicts.  Right now there is nothing tying the two together other than the
	CU name: fix this by introducing a new field in the ctf_dict_t named
	ctf_link_in_out, which (for input dicts) points to the associated per-CU
	output dict (if any), and for output dicts points to the associated
	input dict.  At creation time the name used is completely arbitrary:
	it's only important that it be distinct if CTF dicts are distinct.  So,
	when a clash is found, adjust the CU name by sticking the number of
	elements in the input on the end.  At output time, the CU name will
	appear in the linked object, so it matters a little more that it look
	slightly less ugly: in conflicting cases, append an incrementing
	integer, starting at 0.

	This naming scheme is not very helpful, but it's hard to see what else
	we can do.  The input .o name may be the same.  The input .a name is not
	even visible to ctf_link, and even *that* might be the same, because
	.a's can contain many members with the same name, all of which
	participate in the link.  All we really know is that the two have
	distinct dictionaries with distinct types in them, and at least this way
	they are all represented, any any symbols, variables etc referring to
	those types are accurately stored.

	(As a side-effect this also fixes a use-after-free and double-free when
	errors are found during variable or symbol emission.)

	Use the opportunity to prevent a couple of sources of problems, to wit
	changing the active CU mappings when a link has already been done
	(no effect on ld, which doesn't use CU mappings at all), and causing
	multiple consecutive ctf_link's to have the same net effect as just
	doing the last one (no effect on ld, which only ever does one
	ctf_link) rather than having the links be a sort of half-incremental
	not-really-intended mess.

	PR29256, memory leak in obj_elf_section_name
	When handling section names in quotes obj_elf_section_name calls
	demand_copy_C_string, which puts the name on the gas notes obstack.
	Such strings aren't usually freed, since obstack_free frees all more
	recently allocated objects as well as its arg.  When handling
	non-quoted names, obj_elf_section_name mallocs the name.  Due to the
	mix of allocation strategies it isn't possible for callers to free
	names, if that was desirable.  Partially fix this by always creating

	Fix this by not using aggregate initialization for struct line_offset.
	The default member initization already leaves line_offset as {0,
	LINE_OFFSET_UNKNOWN}, so initialization to those values can just go
	away.  The remaining cases are of the form {0, LINE_OFFSET_NONE}, and
	those cases can be better rewritten to delay setting the sign field
	until we know we have a valid offset.

	Eliminate the two-level data structures behind location_specs
	Currently, there's the location_spec hierarchy, and then some
	location_spec subclasses have their own struct type holding all their
	data fields.

	I.e., there is this:

	 location_spec
	   explicit_location_spec
	   linespec_location_spec
	   address_location_spec
	   probe_location_spec

	and then these separate types:

	  explicit_location
	  linespec_location

	where:

	  explicit_location_spec
	     has-a explicit_location
	  linespec_location_spec
	     has-a linespec_location

	This patch eliminates explicit_location and linespec_location,
	inlining their members in the corresponding location_spec type.

	The location_spec subclasses were the ones currently defined in
	location.c, so they are moved to the header.  Since the definitions of
	the classes are now visible, we no longer need location_spec_deleter.

	Some constructors that are used for cloning location_specs, like:

	  explicit explicit_location_spec (const struct explicit_location *loc)

	... were converted to proper copy ctors.

	In the process, initialize_explicit_location is eliminated, and some
	functions that returned the "data type behind a locspec", like
	get_linespec_location are converted to downcast functions, like
	as_linespec_location_spec.

2022-06-17  Pedro Alves  <pedro@palves.net>

	event_location -> location_spec
	Currently, GDB internally uses the term "location" for both the
	location specification the user input (linespec, explicit location, or
	an address location), and for actual resolved locations, like the
	breakpoint locations, or the result of decoding a location spec to
	SaLs.  This is expecially confusing in the breakpoints module, as
	struct breakpoint has these two fields:

	  breakpoint::location;
	  breakpoint::loc;

	"location" is the location spec, and "loc" is the resolved locations.

	And then, we have a method called "locations()", which returns the
	resolved locations as range...

	The location spec type is presently called event_location:

	  /* Location we used to set the breakpoint.  */
	  event_location_up location;

	and it is described like this:

	  /* The base class for all an event locations used to set a stop event
	     in the inferior.  */

	  struct event_location
	  {

	and even that is incorrect...  Location specs are used for finding
	actual locations in the program in scenarios that have nothing to do
	with stop events.  E.g., "list" works with location specs.

	To clean all this confusion up, this patch renames "event_location" to
	"location_spec" throughout, and then all the variables that hold a
	location spec, they are renamed to include "spec" in their name, like
	e.g., "location" -> "locspec".  Similarly, functions that work with
	location specs, and currently have just "location" in their name are
	renamed to include "spec" in their name too.

	gdb/arm: Make sp alias for one of the other stack pointers
	For Cortex-M targets, SP register is never detached from msp or
	psp, it always has the same value as one of them.  Let GDB treat

2022-06-15  Yvan Roux  <yvan.roux@foss.st.com>

	gdb/arm: Track msp and psp
	For Arm Cortex-M33 with security extensions, there are 4 different
	stack pointers (msp_s, msp_ns, psp_s, psp_ns).  To be compatible
	with earlier Cortex-M derivates, the msp and psp registers are
	aliases for one of the 4 real stack pointer registers.

	These are the combinations that exist:
	sp -> msp -> msp_s
	sp -> msp -> msp_ns
	sp -> psp -> psp_s
	sp -> psp -> psp_ns

	This means that when the GDB client is to show the value of "msp",
	the value should always be equal to either "msp_s" or "msp_ns".
	Same goes for "psp".

	To add a bit more context; GDB does not really use the register msp
	(or psp) internally, but they are part of the set of registers which
	are provided by the target.xml file.  As a result, they will be part
	of the set of registers printed by the "info r" command.

	Without this particular patch, GDB will hit the assert in the bottom
	of arm_cache_get_sp_register function.

	gdb: unify two dis_asm_read_memory functions in disasm.c
	After the recent restructuring of the disassembler code, GDB has ended
	up with two identical class static functions, both called
	dis_asm_read_memory, with identical implementations.

	My first thought was to move these out of their respective classes,
	and just make them global functions, then I'd only need a single
	copy.

	And maybe that's the right way to go.  But I disliked that by doing
	that I loose the encapsulation of the method with the corresponding
	disassembler class.

	So, instead, I placed the static method into its own class, and had
	both the gdb_non_printing_memory_disassembler and gdb_disassembler
	classes inherit from this new class as an additional base-class.

	In terms of code generated, I don't think there's any significant
	difference with this approach, but I think this better reflects how
	the function is closely tied to the disassembler.

	There should be no user visible changes after this commit.

2022-06-15  Andrew Burgess  <aburgess@redhat.com>

	gdb: refactor the non-printing disassemblers
	This commit started from an observation I made while working on some
	other disassembler patches, that is, that the function
	gdb_buffered_insn_length, is broken ... sort of.

	I noticed that the gdb_buffered_insn_length function doesn't set up
	the application data field if the disassemble_info structure.

	Further, I noticed that some architectures, for example, ARM, require
	that the application_data field be set, see gdb_print_insn_arm in
	arm-tdep.c.

	And so, if we ever use gdb_buffered_insn_length for ARM, then GDB will
	likely crash.  Which is why I said only "sort of" broken.  Right now
	we don't use gdb_buffered_insn_length with ARM, so maybe it isn't
	broken yet?

	Anyway to prove to myself that there was a problem here I extended the
	disassembler self tests in disasm-selftests.c to include a test of
	gdb_buffered_insn_length.  As I run the test for all architectures, I
	do indeed see GDB crash for ARM.

	To fix this we need gdb_buffered_insn_length to create a disassembler
	that inherits from gdb_disassemble_info, but we also need this new
	disassembler to not print anything.

	And so, I introduce a new gdb_non_printing_disassembler class, this is
	a disassembler that doesn't print anything to the output stream.

	I then observed that both ARC and S12Z also create non-printing
	disassemblers, but these are slightly different.  While the
	disassembler in gdb_non_printing_disassembler reads the instruction
	from a buffer, the ARC and S12Z disassemblers read from target memory
	using target_read_code.

	And so, I further split gdb_non_printing_disassembler into two
	sub-classes, gdb_non_printing_memory_disassembler and
	gdb_non_printing_buffer_disassembler.

	The new selftests now pass, but otherwise, there should be no user
	visible changes after this commit.

	gdb/python: implement the print_insn extension language hook
	This commit extends the Python API to include disassembler support.

	The motivation for this commit was to provide an API by which the user
	could write Python scripts that would augment the output of the
	disassembler.

	To achieve this I have followed the model of the existing libopcodes
	disassembler, that is, instructions are disassembled one by one.  This
	does restrict the type of things that it is possible to do from a
	Python script, i.e. all additional output has to fit on a single line,
	but this was all I needed, and creating something more complex would,
	I think, require greater changes to how GDB's internal disassembler
	operates.

	The disassembler API is contained in the new gdb.disassembler module,
	which defines the following classes:

	  DisassembleInfo

	      Similar to libopcodes disassemble_info structure, has read-only
	  properties: address, architecture, and progspace.  And has methods:
	  __init__, read_memory, and is_valid.

	      Each time GDB wants an instruction disassembled, an instance of
	  this class is passed to a user written disassembler function, by
	  reading the properties, and calling the methods (and other support
	  methods in the gdb.disassembler module) the user can perform and
	  return the disassembly.

	  Disassembler

	      This is a base-class which user written disassemblers should
	  inherit from.  This base class provides base implementations of
	  __init__ and __call__ which the user written disassembler should
	  override.

	  DisassemblerResult

	      This class can be used to hold the result of a call to the
	  disassembler, it's really just a wrapper around a string (the text
	  of the disassembled instruction) and a length (in bytes).  The user
	  can return an instance of this class from Disassembler.__call__ to
	  represent the newly disassembled instruction.

	The gdb.disassembler module also provides the following functions:

	  register_disassembler

	      This function registers an instance of a Disassembler sub-class
	  as a disassembler, either for one specific architecture, or, as a
	  global disassembler for all architectures.

	  builtin_disassemble

	      This provides access to GDB's builtin disassembler.  A common
	  use case that I see is augmenting the existing disassembler output.
	  The user code can call this function to have GDB disassemble the
	  instruction in the normal way.  The user gets back a
	  DisassemblerResult object, which they can then read in order to
	  augment the disassembler output in any way they wish.

	      This function also provides a mechanism to intercept the
	  disassemblers reads of memory, thus the user can adjust what GDB
	  sees when it is disassembling.

	The included documentation provides a more detailed description of the
	API.

	There is also a new CLI command added:

	  maint info python-disassemblers

	This command is defined in the Python gdb.disassemblers module, and
	can be used to list the currently registered Python disassemblers.

	gdb: add extension language print_insn hook
	This commit is setup for the next commit.

	In the next commit I will add a Python API to intercept the print_insn
	calls within GDB, each print_insn call is responsible for
	disassembling, and printing one instruction.  After the next commit it
	will be possible for a user to write Python code that either wraps
	around the existing disassembler, or even, in extreme situations,
	entirely replaces the existing disassembler.

	This commit does not add any new Python API.

	What this commit does is put the extension language framework in place
	for a print_insn hook.  There's a new callback added to 'struct
	extension_language_ops', which is then filled in with nullptr for Python
	and Guile.

	Finally, in the disassembler, the code is restructured so that the new
	extension language function ext_lang_print_insn is called before we
	delegate to gdbarch_print_insn.

	After this, the next commit can focus entirely on providing a Python
	implementation of the new print_insn callback.

	There should be no user visible change after this commit.

2022-06-15  Andrew Burgess  <andrew.burgess@embecosm.com>

	gdb: add new base class to gdb_disassembler
	The motivation for this change is an upcoming Python disassembler API
	that I would like to add.  As part of that change I need to create a
	new disassembler like class that contains a disassemble_info and a
	gdbarch.  The management of these two objects is identical to how we
	manage these objects within gdb_disassembler, so it might be tempting
	for my new class to inherit from gdb_disassembler.

	The problem however, is that gdb_disassembler has a tight connection
	between its constructor, and its print_insn method.  In the
	constructor the ui_file* that is passed in is replaced with a member
	variable string_file*, and then in print_insn, the contents of the
	member variable string_file are printed to the original ui_file*.

	What this means is that the gdb_disassembler class has a tight
	coupling between its constructor and print_insn; the class just isn't
	intended to be used in a situation where print_insn is not going to be
	called, which is how my (upcoming) sub-class would need to operate.

	My solution then, is to separate out the management of the
	disassemble_info and gdbarch into a new gdb_disassemble_info class,
	and make this class a parent of gdb_disassembler.

	In arm-tdep.c and mips-tdep.c, where we used to cast the
	disassemble_info->application_data to a gdb_disassembler, we can now
	cast to a gdb_disassemble_info as we only need to access the gdbarch
	information.

	Now, my new Python disassembler sub-class will still want to print
	things to an output stream, and so we will want access to the
	dis_asm_fprintf functionality for printing.

	However, rather than move this printing code into the
	gdb_disassemble_info base class, I have added yet another level of
	hierarchy, a gdb_printing_disassembler, thus the class structure is
	now:

	  struct gdb_disassemble_info {};
	  struct gdb_printing_disassembler : public gdb_disassemble_info {};
	  struct gdb_disassembler : public gdb_printing_disassembler {};

	In a later commit my new Python disassembler will inherit from
	gdb_printing_disassembler.

	The reason for adding the additional layer to the class hierarchy is
	that in yet another commit I intend to rewrite the function
	gdb_buffered_insn_length, and to do this I will be creating yet more
	disassembler like classes, however, these will not print anything,
	thus I will add a gdb_non_printing_disassembler class that also
	inherits from gdb_disassemble_info.  Knowing that that change is
	coming, I've gone with the above class hierarchy now.

	There should be no user visible changes after this commit.

	gdb/python: convert gdbpy_err_fetch to use gdbpy_ref
	Convert the gdbpy_err_fetch class to make use of gdbpy_ref, this
	removes the need for manual reference count management, and allows the
	destructor to be removed.

	There should be no functional change after this commit.

	I think this cleanup is worth doing on its own, however, in a later
	commit I will want to copy instances of gdbpy_err_fetch, and switching
	to using gdbpy_ref means that I can rely on the default copy
	constructor, without having to add one that handles the reference
	counts, so this is good preparation for that upcoming change.

	Implement lazy FPU initialization for ravenscar
	Some ravenscar runtimes implement lazy FPU handling.  On these
	runtimes, the FPU is only initialized when a task tries to use it.
	Furthermore, the FP registers aren't automatically saved on a task
	switch -- instead, the save is deferred until the new task tries to
	use the FPU.  Furthermore, each task's context area has a flag
	indicating whether the FPU has been initialized for this task.

	This patch teaches GDB to understand this implementation.  When
	fetching or storing registers, GDB now checks to see whether the live
	FP registers should be used.  If not, the task's saved FP registers
	will be used if the task has caused FPU initialization.

	Currently only AArch64 uses this code.  bb-runtimes implements this
	for ARM as well, but GDB doesn't yet have an arm-ravenscar-thread.c.

2022-06-14  Tom Tromey  <tromey@adacore.com>

	Reimplement ravenscar registers using tables
	Currently, the ravenscar-thread implementation for each architecture
	is written by hand.  However, these are actually written by
	copy-paste.  It seems better to switch to a table-driven approach.

	The previous code also fetched all registers whenever any register was
	requested.  This is corrected in the new implementation.

	Fix bugs in aarch64-ravenscar-thread.c
	We found a few bugs in aarch64-ravenscar-thread.c.

	First, some of the register offsets were incorrect.  The "bb-runtimes"
	file for this runtime had the wrong offsets in comments, which GDB
	took to be correct.  However, those comments didn't account for
	alignment.  This patch adjusts the offsets.

	Next, the "FPU Saved field" is not a register -- it is an
	implementation detail of the runtime.  This is removed.

	Finally, I think the FP registers are actually named V0-V31, and the
	"Q" names are pseudo-registers.  This patch fixes the comment.

	Yes, the commit 0aabe54e6222 changes likely should go in too.  I'm a
	little wary of adding all the sanity checks to elf_core_file_p since

	Debug support for global alias variable
	Starting with (future) Clang 15 (since
	https://reviews.llvm.org/D120989), Clang emits the DWARF information
	of global alias variables as DW_TAG_imported_declaration.  However,
	GDB does not handle it.  It incorrectly always reads this tag as
	C++/Fortran imported declaration (type alias, namespace alias and
	Fortran module).  This commit adds support to handle this tag as an
	alias variable.

	This change fixes the failures in the gdb.base/symbol-alias.exp
	testcase with current git Clang.  This testcase is also updated to
	test nested (recursive) aliases.

	BFD_RELOC_MIPS_16
	MIPS should not be using BFD_RELOC_16 for its R_MIPS_16 relocation,
	since R_MIPS_16 specifies a 16-bit field in a 32-bit word.
	BFD_RELOC_16, emitted by generic code to handle fixups on 16-bit data
	directives, expects fixups to operate on the whole of a 16-bit word.

	This patch corrects the problem by using BFD_RELOC_MIPS_16, a new bfd
	reloc that is used to generate R_MIPS_16.  BFD_RELOC_16 is handled in
	md_apply_fix for cases where the fixup can be applied at assembly
	time.  Like BFD_RELOC_8, BFD_RELOC_16 now has no corresponding object
	file relocation, and thus .half, .hword, .short and .dc.w must be
	resolved at assembly time.  BFD_RELOC_MIPS_REL16 is removed by this
	patch since it isn't used.

2022-06-13  Jan Beulich  <jbeulich@suse.com>

	x86: replace global scratch buffer
	With its movement to the stack, and with the subsequent desire to
	initialize the entire instr_info instances, this has become doubly
	inefficient. Individual users have better knowledge of how big a buffer
	they need, and in a number of cases going through an intermediate buffer
	can be avoided altogether.

	Having got confirmation that it wasn't intentional to print memory
	operand displacements with inconsistent style, print_displacement() is
	now using dis_style_address_offset consistently (eliminating the need
	for callers to pass in a style).

	While touching print_operand_value() also convert its "hex" parameter to
	bool. And while altering (and moving) oappend_immediate(), fold
	oappend_maybe_intel_with_style() into its only remaining caller. Finally
	where doing adjustments, use snprintf() in favor of sprintf().

	x86: shrink prefix related disassembler state fields
	By changing the values used for "artificial" prefix values,
	all_prefixes[] can be shrunk to array of unsigned char. All that
	additionally needs adjusting is the printing of possible apparently
	standalone prefixes when recovering from longjmp(): Simply check
	whether any prefixes were successfully decoded, to avoid converting
	opcode bytes matching the "artificial" values to prefix mnemonics.

	Similarly by re-arranging the bits assigned to PREFIX_* mask values
	we can fit all segment register masks in a byte and hence shrink
	active_seg_prefix to unsigned char.

	Somewhat similarly with last_*_prefix representing offsets into the
	opcode being disassembled, signed char is sufficient to hold all possible

	x86: properly initialize struct instr_info instance(s)
	Commit 39fb369834a3 ("opcodes: Make i386-dis.c thread-safe") introduced
	a lot of uninitialized data. Alan has in particular observed ubsan
	taking issue with the loop inverting the order of operands, where
	op_riprel[] - an array of bool - can hold values other than 0 or 1.

	Move instantiation of struct instr_info into print_insn() (thus having
	just a single central point), and make use of C99 dedicated initializers
	to fill fields right in the initializer where possible. This way all
	fields not explicitly initialized will be zero-filled, which in turn
	allows dropping of some other explicit initialization later in the
	function or in ckprefix(). Additionally this removes a lot of
	indirection, as all "ins->info" uses can simply become "info".

	Make one further arrangement though, to limit the amount of data needing
	(zero)initializing on every invocation: Convert the op_out structure
	member to just an array of pointers, with the actual arrays living
	inside print_insn() (and, as befoe, having just their 1st char filled
	with nul).

	While there, instead of adjusting print_insn()'s forward declaration,
	arrange for no such declaration to be needed in the first place.

	Fix self-test failure in addrmap
	Mark pointed out that my recent addrmap C++-ficiation changes caused a
	regression in the self-tests.  This patch fixes the problem by
	updating this test not to allocate the mutable addrmap on an obstack.

	Remove psymtab_addrmap
	While working on addrmaps, I noticed that psymtab_addrmap is no longer
	needed now.  It was introduced in ancient times as an optimization for
	DWARF, but no other symbol reader was ever updated to use it.  Now
	that DWARF does not use psymtabs, it can be deleted.

	Use malloc for mutable addrmaps
	Mutable addrmaps currently require an obstack.  This was probably done
	to avoid having to call splay_tree_delete, but examination of the code
	shows that all mutable obstacks have a limited lifetime -- now it's
	simple to treat them as ordinary C++ objects, in some cases
	stack-allocating them, and have a destructor to make the needed call.
	This patch implements this change.

	Remove addrmap::create_fixed
	addrmap::create_fixed is just a simple wrapper for 'new', so remove it
	in favor of uses of 'new'.

	Remove addrmap_create_mutable
	This removes addrmap_create_mutable in favor of using 'new' at the
	spots where the addrmap is created.

	Remove addrmap wrapper functions
	This removes the various addrmap wrapper functions in favor of simple
	method calls on the objects themselves.

	Move addrmap classes to addrmap.h
	This moves the addrmap class definitions to addrmap.h.  This is safe
	to do now that the contents are private.

	Privacy for addrmap_mutable
	This changes addrmap_mutable so that its data members are private.

	Privacy for addrmap_fixed
	This changes addrmap_fixed so that its data members are private.
	It also makes struct addrmap_transition private as well.

	Use inheritance for addrmap
	This is a simply C++-ification of the basics of addrmap: it uses
	virtual methods rather than a table of function pointers, and it
	changes the concrete implementations to be subclasses.

	Fix warning-avoidance initialization in xcoffread.c
	With the registry rewrite series, on Fedora 34, I started seeing this
	error in xcoffread.c:

	../../binutils-gdb/gdb/xcoffread.c: In function ‘void read_xcoff_symtab(objfile*, legacy_psymtab*)’:
	../../binutils-gdb/gdb/xcoffread.c:948:25: error: ‘main_aux’ is used uninitialized [-Werror=uninitialized]

	I don't know why this error started suddenly... that seems weird,
	because it's not obviously related to the changes I made.

	Looking into it, it seems this line was intended to avoid a similar

	This patch avoids the warning by initializing using "{}".  I'm

	Fix comparison of unsigned long int to int in record_linux_system_call.
	The if statement in case gdb_sys_ioctl in function
	record_linux_system_call in file gdb/linux-record.c is as follows:

	   if (tmpulongest == tdep->ioctl_FIOCLEX
	      || tmpulongest == tdep->ioctl_FIONCLEX
	    ....
	      || tmpulongest == tdep->ioctl_TCSETSW
	     ...
	   }

	The PowerPC ioctl value for ioctl_TCSETW is 0x802c7415.  The variable
	ioctl_TCSETW is defined in gdb/linux-record.h as an int.  The TCSETW value
	has the MSB set to one so it is a negative integer.  The comparison of the
	unsigned long value tmpulongest to a negative integer value for
	ioctl_TCSETSW fails.

	This patch changes the declarations for the ioctl_* values in struct
	linux_record_tdep to unsigned long to fix the comparisons between
	tmpulongest and the tdep->ioctl_* values.

	An additional test gdb.reverse/test_ioctl_TCSETSW.exp is added to verify
	the gdb record_linux_system_call() if statement for the ioctl TCSETSW
	succeeds.

	This patch has been tested on Power 10 and Intel with no test failures.

	PowerPC, correct the gdb ioctl values for TCGETS, TCSETS, TCSETSW and TCSETSF.
	Some of the ioctl numbers are based on the size of kernel termios structure.
	Currently the PowerPC GDB definitions are "hard coded" into the ioctl
	number.

	The current PowerPC values for TCGETS, TCSETS, TCSETSW and TCSETSF are
	defined in gdb/ppc-linux-tdep.c as:

	  record_tdep->ioctl_TCGETS = 0x403c7413;
	  record_tdep->ioctl_TCSETS = 0x803c7414;
	  record_tdep->ioctl_TCSETSW = 0x803c7415;
	  record_tdep->ioctl_TCSETSF = 0x803c7416;

	Where the termios structure size is in hex digits [5:4] as 0x3c.

	The definition for the PowerPC termios structure is given in:
	  arch/powerpc/include/uapi/asm/termbits.h

	The size of the termios data structure in this file is 0x2c not 0x3c.

	This patch changes the hex digits for the size of the PowerPC termios size
	in the ioctl values for TCGETS, TCSETS, TCSETSW and TCSETSF to 0x2c.
	This patch also changes the hard coding to generate the number based on a
	it easier to update the ioctl numbers.

2022-06-10  Andrew Burgess  <aburgess@redhat.com>

	gdb/testsuite: remove definition of true/false from gdb_compiler_info
	Since pretty much forever the get_compiler_info function has included
	these lines:

	    # Most compilers will evaluate comparisons and other boolean
	    # operations to 0 or 1.
	    uplevel \#0 { set true 1 }
	    uplevel \#0 { set false 0 }

	These define global variables true (to 1) and false (to 0).

	It seems odd to me that these globals are defined in
	get_compiler_info, I guess maybe the original thinking was that if a
	compiler had different true/false values then we would detect it there
	and define true/false differently.

	I don't think we should be bundling this logic into get_compiler_info,
	it seems weird to me that in order to use $true/$false a user needs to
	first call get_compiler_info.

	It would be better I think if each test script that wants these
	variables just defined them itself, if in the future we did need
	different true/false values based on compiler version then we'd just
	do:

	  if { [test_compiler_info "some_pattern"] } {
	    # Defined true/false one way...
	  } else {
	    # Defined true/false another way...
	  }

	But given the current true/false definitions have been in place since
	at least 1999, I suspect this will not be needed any time soon.

	Given that the definitions of true/false are so simple, right now my
	suggestion is just to define them in each test script that wants
	them (there's not that many).  If we ever did need more complex logic
	then we can always add a function in gdb.exp that sets up these
	globals, but that seems overkill for now.

	There should be no change in what is tested after this commit.

	gdb/aarch64: fix 32-bit arm compatibility
	GDB's ability to run 32-bit ARM processes on an AArch64 native target
	is currently broken.  The test gdb.multi/multi-arch.exp currently
	fails with a timeout.

	The cause of these problems is the following three functions:

	  aarch64_linux_nat_target::thread_architecture
	  aarch64_linux_nat_target::fetch_registers
	  aarch64_linux_nat_target::store_registers

	What has happened, over time, is that these functions have been
	modified, forgetting that any particular thread (running on the native
	target) might be an ARM thread, or might be an AArch64 thread.

	The problems always start with a line similar to this:

	  aarch64_gdbarch_tdep *tdep
	    = (aarch64_gdbarch_tdep *) gdbarch_tdep (inf->gdbarch);

	The problem with this line is that if 'inf->gdbarch' is an ARM
	architecture, then gdbarch_tdep will return a pointer to an
	arm_gdbarch_tdep object, not an aarch64_gdbarch_tdep object.  The
	result of the above cast will, as a consequence, be undefined.

	In aarch64_linux_nat_target::thread_architecture, after the undefined
	cast we then proceed to make use of TDEP, like this:

	  if (vq == tdep->vq)
	    return inf->gdbarch;

	Obviously at this point the result is undefined, but, if this check
	returns false we then proceed with this code:

	  struct gdbarch_info info;
	  info.bfd_arch_info = bfd_lookup_arch (bfd_arch_aarch64, bfd_mach_aarch64);
	  info.id = (int *) (vq == 0 ? -1 : vq);
	  return gdbarch_find_by_info (info);

	As a consequence we will return an AArch64 gdbarch object for our ARM
	thread!  Things go downhill from there on.

	There are similar problems, with similar undefined behaviour, in the
	fetch_registers and store_registers functions.

	The solution is to make use of a check like this:

	  if (gdbarch_bfd_arch_info (inf->gdbarch)->bits_per_word == 32)

	If the word size is 32 then we know we have an ARM architecture.  We
	just need to make sure that we perform this check before trying to
	read the tdep field.

	In aarch64_linux_nat_target::thread_architecture a little reordering,
	and the addition of the above check allows us to easily avoid the
	undefined behaviour.

	For fetch_registers and store_registers I made the decision to split
	each of the functions into two new helper functions, and so
	aarch64_linux_nat_target::fetch_registers now calls to either
	aarch64_fetch_registers or aarch32_fetch_registers, and there's a
	similar change for store_registers.

	One thing I had to decide was whether to place the new aarch32_*
	functions into the aarch32-linux-nat.c file.  In the end I decided to
	NOT place the functions there, but instead leave them in
	aarch64-linux-nat.c, my reasoning was this:

	The existing functions in that file are shared from arm-linux-nat.c
	and aarch64-linux-nat.c, this generic code to support 32-bit ARM
	debugging from either native target.

	In contrast, the two new aarch32 functions I have added _only_ make
	sense when debugging on an AArch64 native target.  These function
	shouldn't be called from arm-linux-nat.c at all, and so, if we places
	the functions into aarch32-linux-nat.c, the functions would be built
	into a 32-bit ARM GDB, but never used.

	With that said, there's no technical reason why they couldn't go in
	aarch32-linux-nat.c, so if that is preferred I'm happy to move them.

	After this commit the gdb.multi/multi-arch.exp passes.

	gdb/testsuite: solve problems with compiler_info caching
	After this commit:

	  commit 44d469c5f85a4243462b8966722dafa62b602bf5
	  Date:   Tue May 31 16:43:44 2022 +0200

	      gdb/testsuite: add Fortran compiler identification to GDB

	Some regressions were noticed:

	  https://sourceware.org/pipermail/gdb-patches/2022-May/189673.html

	The problem is associated with how compiler_info variable is cached
	between calls to get_compiler_info.

	Even before the above commit, get_compiler_info supported two
	language, C and C++.  Calling get_compiler_info would set the global
	compiler_info based on the language passed as an argument to
	get_compiler_info, and, in theory, compiler_info would not be updated
	for the rest of the dejagnu run.

	This obviously is slightly broken behaviour.  If the first call to
	get_compiler_info was for the C++ language then compiler_info would be
	set based on the C++ compiler in use, while if the first call to
	get_compiler_info was for the C language then compiler_info would be
	set based on the C compiler.

	This probably wasn't very noticable, assuming a GCC based test
	environment then in most cases the C and C++ compiler would be the
	same version.

	However, if the user starting playing with CC_FOR_TARGET or
	CXX_FOR_TARGET, then they might not get the behaviour they expect.

	Except, to make matters worse, most of the time, the user probably
	would get the behaviour they expected .... except when they didn't!
	I'll explain:

	In gdb.exp we try to avoid global variables leaking between test
	scripts, this is done with the help of the two procs
	gdb_setup_known_globals and gdb_cleanup_globals.  All known globals
	are recorded before a test script starts, and then, when the test
	script ends, any new globals are deleted.

	Normally, compiler_info is only set as a result of a test script
	calling get_compiler_info or test_compiler_info.  This means that the
	compiler_info global will not exist when the test script starts, but
	will exist when the test script end, and so, the compiler_info
	variable is deleted at the end of each test.

	This means that, in reality, the compiler_info is recalculated once
	for each test script, hence, if a test script just checks on the C
	compiler, or just checks on the C++ compiler, then compiler_info will
	be correct and the user will get the behaviour they expect.

	However, if a single test script tries to check both the C and C++
	compiler versions then this will not work (even before the above
	commit).

	The situation is made worse be the behaviour or the load_lib proc.
	This proc (provided by dejagnu) will only load each library once.
	This means that if a library defines a global, then this global would
	normally be deleted at the end of the first test script that includes
	the library.

	As future attempts to load the library will not actually reload it,
	then the global will not be redefined and would be missing for later
	test scripts that also tried to load that library.

	To work around this issue we override load_lib in gdb.exp, this new
	version adds all globals from the newly loaded library to the list of
	globals that should be preserved (not deleted).

	And this is where things get interesting for us.  The library
	trace-support.exp includes calls, at the file scope, to things like
	is_amd64_regs_target, which cause get_compiler_info to be called.
	This means that after loading the library the compiler_info global is
	defined.

	Our override of load_lib then decides that this new global has to be
	preserved, and adds it to the gdb_persistent_globals array.

	From that point on compiler_info will never be recomputed!

	This commit addresses all the caching problems by doing the following:

	Change the compiler_info global into compiler_info_cache global.  This
	new global is an array, the keys of this array will be each of the
	supported languages, and the values will be the compiler version for
	that language.

	Now, when we call get_compiler_info, if the compiler information for
	the specific language has not been computed, then we do that, and add
	it to the cache.

	Next, compiler_info_cache is defined by calling
	gdb_persistent_global.  This automatically adds the global to the list
	of persistent globals.  Now the cache will not be deleted at the end
	of each test script.

	This means that, for a single test run, we will compute the compiler
	version just once for each language, this result will then be cached
	between test scripts.

	Finally, the legacy 'gcc_compiled' flag is now only set when we call
	get_compiler_info with the language 'c'.  Without making this change
	the value of 'gcc_compiled' would change each time a new language is
	passed to get_compiler_info.  If the last language was e.g. Fortran,
	then gcc_compiled might be left false.

	gdb/testsuite: handle errors better in test_compiler_info
	Now that get_compiler_info might actually fail (if the language is not
	handled), then we should try to handle this failure better in
	test_compiler_info.

	After this commit, if get_compiler_info fails then we will return a
	suitable result depending on how the user called test_compiler_info.

	If the user does something like:

	  set version [test_compiler_info "" "unknown-language"]

	Then test_compiler_info will return an empty string.  My assumption is
	that the user will be trying to match 'version' against something, and
	the empty string hopefully will not match.

	If the user does something like:

	  if { [test_compiler_info "some_pattern" "unknown-language"] } {
	    ....
	  }

	Then test_compiler_info will return false which seems the obvious
	choice.

	There should be no change in the test results after this commit.

2022-06-09  Andrew Burgess  <aburgess@redhat.com>

	gdb/testsuite: make 'c' default language for get/test compiler info
	This commit is a minor cleanup for the two functions (in gdb.exp)
	get_compiler_info and test_compiler_info.

	Instead of using the empty string as the default language, and just
	"knowing" that this means the C language.  Make this explicit.  The
	language argument now defaults to "c" if not specified, and the if
	chain in get_compiler_info that checks the language not explicitly
	handles "c" and gives an error for unknown languages.

	This is a good thing, now that the API appears to take a language, if
	somebody does:

	  test_compiler_info "xxxx" "rust"

	to check the version of the rust compiler then we will now give an
	error rather than just using the C compiler and leaving the user
	having to figure out why they are not getting the results they
	expect.

	After a little grepping, I think the only place we were explicitly
	passing the empty string to either get_compiler_info or
	test_compiler_info was in gdb_compile_shlib_1, this is now changed to
	pass "c" as the default language.

	There should be no changes to the test results after this commit.

	compiler_info to retrieve gcc's major version.  This is discouraged and
	(as can be read in a comment in compiler.c) compiler_info should be
	local to get_compiler_info and test_compiler_info.

	The preferred way of getting the compiler string is via calling
	test_compiler_info without arguments.  Gcc_major_version was changed to
	do that.

	gdb/testsuite: resolve duplicate test names in gdb.threads/tls.exp
	While running the gdb.threads/tls.exp test with a GDB configured
	without Python, I noticed some duplicate test names.

	This is caused by a call to skip_python_tests that is within a proc
	that is called multiple times by the test script.  Each call to
	skip_python_tests results in a call to 'unsupported', and this causes
	the duplicate test names.

	After this commit we now call skip_python_tests just once and place
	the result into a variable.  Now, instead of calling skip_python_tests
	multiple times, we just check the variable.

	There should be no change in what is tested after this commit.

	gdb/testsuite: resolve duplicate test name in gnu_vector.exp
	While testing on AArch64 I spotted a duplicate test name in the

	While I was in the area I updated a 'gdb_test_multiple' call to make
	use of $gdb_test_name.

	gdb: make throw_perror_with_name static
	The throw_perror_with_name function is not used outside of utils.c
	right now.  And as perror_with_name is just a wrapper around
	throw_perror_with_name, then any future calls would be to
	perror_with_name.

	Lets make throw_perror_with_name static.

	gdb: remove trailing '.' from perror_with_name calls
	I ran into this error while working on AArch64 GDB:

	  Unable to fetch VFP registers.: Invalid argument.

	Notice the '.:' in the middle of this error message.

	This is because of this call in aarch64-linux-nat.c:

	  perror_with_name (_("Unable to fetch VFP registers."));

	The perror_with_name function take a string, and adds ': <message>' to
	the end the string, so I don't think the string that we pass to
	perror_with_name should end in '.'.

	This commit removes all of the trailing '.' characters from
	perror_with_name calls, which give more readable error messages.

	I don't believe that any of these errors are tested in the
	testsuite (after a little grepping).

	Move CU queue to dwarf2_per_objfile
	The CU queue is a member of dwarf2_per_bfd, but it is only used when
	expanding CUs.  Also, the dwarf2_per_objfile destructor checks the
	queue -- however, if the per-BFD object is destroyed first, this will
	not work.  This was pointed out Lancelot as fallout from the patch to
	rewrite the registry system.

	This patch avoids this problem by moving the queue to the per-objfile
	object.

	libopcodes: extend the styling within the i386 disassembler
	The i386 disassembler is pretty complex.  Most disassembly is done
	indirectly; operands are built into buffers within a struct instr_info
	instance, before finally being printed later in the disassembly
	process.

	Sometimes the operand buffers are built in a different order to the
	order in which they will eventually be printed.

	Each operand can contain multiple components, e.g. multiple registers,
	immediates, other textual elements (commas, brackets, etc).

	When looking for how to apply styling I guess the ideal solution would
	be to move away from the operands being a single string that is built
	up, and instead have each operand be a list of "parts", where each
	part is some text and a style.  Then, when we eventually print the
	operand we would loop over the parts and print each part with the
	correct style.

	But it feels like a huge amount of work to move from where we are
	now to that potentially ideal solution.  Plus, the above solution
	would be pretty complex.

	So, instead I propose a .... different solution here, one that works
	with the existing infrastructure.

	As each operand is built up, piece be piece, we pass through style
	information.  This style information is then encoded into the operand
	buffer (see below for details).  After this the code can continue to
	operate as it does right now in order to manage the set of operand
	buffers.

	Then, as each operand is printed we can split the operand buffer into
	chunks at the style marker boundaries, with each chunk being printed
	with the correct style.

	For encoding the style information I use a single character, currently
	\002, followed by the style encoded as a single hex digit, followed
	again by the \002 character.

	This of course relies on there not being more than 16 styles, but that
	is currently true, and hopefully will remain true for the foreseeable
	future.

	The other major concern that has arisen around this work is whether
	the escape character could ever be encountered in output naturally
	generated by the disassembler.  If this did happen then the escape
	characters would be stripped from the output, and the wrong styling
	would be applied.

	However, I don't believe that this is currently a problem.
	Disassembler content comes from a number of sources.  First there's
	content that copied directly from the i386-dis.c file, this is things
	like register names, and other syntax elements (brackets, commas,
	etc).  We can easily check that the i386-dis.c file doesn't contain
	our special character.

	The next source of content are immediate operands.  The text for these
	operands is generated by calls into libc.  By selecting a
	non-printable character we can be confident that this is not something
	that libc will generate as part of an immediate representation.

	The other output that appears to be from the disassembler is operands
	that contain addresses and (possibly) symbol names.  It is quite
	possible that a symbol name might contain any special character we
	could imagine, so is this a problem?

	I don't think it is, we don't actually print address and symbol
	operands through the disassembler, instead, the disassembler calls
	back to the user (objdump, gdb, etc) to print the address and symbol
	on its behalf.  This content is printed directly to the output stream,
	it does not pass through the i386 disassembler output buffers.  As a
	result, we never check this particular output for styling escape
	characters.

	In some (not very scientific) benchmarking on my machine,
	disassembling a reasonably large (142M) shared library, I'm not seeing
	any significant slow down in disassembler speed with this change.

	Most instructions are now being fully syntax highlighted when I
	disassemble using the --disassembler-color=extended-color option.  I'm
	sure that there are probably still a few corner cases that need fixing
	up, but we can come back to them later I think.

	When disassembler syntax highlighting is not being used, then there
	should be no user visible changes after this commit.

	Use subclasses of windows_process_info
	This changes windows_process_info to use virtual methods for its
	callbacks, and then changes the two clients of this code to subclass
	this class to implement the methods.

	I considered using CRTP here, but that would require making the new
	structures visible to the compilation of of nat/windows-nat.c.  This
	seemed like a bit of a pain, so I didn't do it.

	This change then lets us change all the per-inferior globals to be
	members of the new subclass.  Note that there can still only be a
	single inferior -- currently there's a single global of the new type.
	This is just another step toward possibly implementing multi-inferior
	for Windows.

	It's possible this could be cleaned up further... ideally I'd like to
	move more of the data into the base class.  However, because gdb
	supports Cygwin and gdbserver does not, and because I don't have a way
	to build or test Cygwin, larger refactorings are difficult.

	Turn some windows-nat.c static functions into methods
	This patch turns some windows-nat.c static functions into methods on

	Allow ASLR to be disabled on Windows
	On Windows, it is possible to disable ASLR when creating a process.
	This patch adds code to do this, and hooks it up to gdb's existing
	disable-randomization feature.  Because the Windows documentation
	cautions that this isn't available on all versions of Windows, the
	CreateProcess wrapper function is updated to make the attempt, and
	then fall back to the current approach if it fails.

	Introduce wrapper for CreateProcess
	This is a small refactoring that introduces a wrapper for the Windows
	CreateProcess function.  This is done to make the next patch a bit

	Consolidate "Python API" sections in NEWS
	I noticed that the gdb NEWS file had two "Python API" sections in
	"Changes since GDB 12".  This patch consolidates the two.  I chose to
	preserve the second one, first because it is longer, and second
	because I felt that user command changes should come before API
	changes.

	Simplify varobj "change" logic
	varobj used to store 'print_value' as a C string, where NULL was a
	valid value, and so it had logic to handle this situation.  However,
	at some point this was changed to be a std::string, and so the code
	can be simplified in this spot.

	Running selftest unpack_field_as_long::A6.
	...

	By now I know that A6 is an arc architecture, but for others that's less

	Fix this by using unpack_field_as_long::arc::A6 instead.

	This then introduces redundant names like arm::arm, so try to avoid those,

	...

	The insn is written to gdb_stdout, and there is code in the selftest to add a
	newline after the insn, which writes to stream().

	The stream() ui_file points into a string buffer, which the disassembler uses
	before writing to gdb_stdout, so writing into it after the disassembler has
	finished has no effect.

	Fix this by using gdb_stdlog and debug_printf (which is what the unit test
	infrastructure itself uses) instead, such that we have:
	...
	Running selftest print_one_insn::A6.
	.shor   0x783e

	[gdb/fortran] Fix literal truncation
	As mentioned in commit 5b758627a18 ("Make gdb.base/parse_number.exp test all

	...
	    There might be a bug that 32-bit fortran truncates 64-bit values to
	    32-bit, given "p/x 0xffffffffffffffff" returns "0xffffffff".
	...

	More concretely, we have:
	...
	$ for arch in i386:x86-64 i386; do \
	    gdb -q -batch -ex "set arch $arch" -ex "set lang fortran" \
	      -ex "p /x 0xffffffffffffffff"; \

	The target architecture is set to "i386:x86-64".
	$1 = 0xffffffffffffffff
	The target architecture is set to "i386".
	$1 = 0xffffffff
	...

	Fix this by adding a range check in parse_number in gdb/f-exp.y.

	[gdb/c] Fix type of 2147483648 and literal truncation
	[ Assuming arch i386:x86-64, sizeof (int) == 4,
	sizeof (long) == sizeof (long long) == 8. ]

	Currently we have (decimal for 0x80000000):
	...
	(gdb) ptype 2147483648
	type = unsigned int
	...

	According to C language rules, unsigned types cannot be used for decimal
	constants, so the type should be long instead (reported in PR16377).

	Fix this by making sure the type of 2147483648 is long.

	The next interesting case is (decimal for 0x8000000000000000):
	...
	(gdb) ptype 9223372036854775808
	type = unsigned long
	...

	According to the same rules, unsigned long is incorrect.

	Current gcc uses __int128 as type, which is allowed, but we don't have that
	available in gdb, so the strict response here would be erroring out with
	overflow.

	Older gcc without __int128 support, as well as clang use an unsigned type, but with
	a warning.  Interestingly, clang uses "unsigned long long" while gcc uses
	"unsigned long", which seems the better choice.

	Given that the compilers allow this as a convience, do the same in gdb
	and keep type "unsigned long", and make this explicit in parser and test-case.

	Furthermore, make sure we error out on overflow instead of truncating in all
	cases.

	[gdb/testsuite] Test more values in gdb.base/parse_numbers.exp
	Currently we only test value 0xffffffffffffffff in test-case
	gdb.base/parse_numbers.exp.

	Test more interesting values, both in decimal and hex format, as well as
	negative decimals for language modula-2.

	This results in an increase in total tests from 15572 to 847448 (55 times
	more tests).

	Balance out the increase in runtime by reducing the number of architectures
	tested: only test one architecture per sizeof longlong/long/int/short
	combination, while keeping the possibility intact to run with all
	architectures (through setting a variable in the test-case)

	Results in slight reduction of total tests: 15572 -> 13853.

	Document interesting cases in the expected results:
	- wrapping from unsigned to signed
	- truncation
	- PR16377: using unsigned types to represent decimal constants in C

	Running the test-case with a gdb build with -fsanitize=undefined, we trigger
	two UB errors in the modula-2 parser, filed as PR29163.

	[gdb] Fix warning in foreach_arch selftests
	When running the selftests, I run into:
	...
	$ gdb -q -batch -ex "maint selftest"
	  ...
	Running selftest execute_cfa_program::aarch64:ilp32.
	warning: A handler for the OS ABI "GNU/Linux" is not built into this
	configuration of GDB.  Attempting to continue with the default aarch64:ilp32
	settings.
	...
	and likewise for execute_cfa_program::i8086 and
	execute_cfa_program::ia64-elf32.

	The warning can easily be reproduced outside the selftests by doing:
	...
	$ gdb -q -batch -ex "set arch aarch64:ilp32"
	...
	and can be prevented by first doing "set osabi none".

	Fix the warning by setting osabi to none while doing selftests that iterate
	over all architectures.

	This causes a regression in the print_one_insn selftests for the ARC
	architecture.

	The problem is pre-existing, and can be demonstrated (already without this
	patch) using:
	...
	$ gdb -q -batch -ex "set osabi none" -ex "maint selftest print_one_insn::A6"
	Running selftest print_one_insn::A6.
	Self test failed: Cannot access memory at address 0x0
	Ran 1 unit tests, 1 failed
	$
	...

	For ARC, we use the generic case in print_one_insn_test, containing this code:
	...
	       int kind = gdbarch_breakpoint_kind_from_pc (gdbarch, &pc);
	       ...
	       insn = gdbarch_sw_breakpoint_from_kind (gdbarch, kind, &bplen);
	...

	The problem is that with osabi linux we trigger:
	...
	static int
	arc_linux_breakpoint_kind_from_pc (struct gdbarch *gdbarch, CORE_ADDR *pcptr)
	{
	  return trap_size;
	}
	...
	but with osabi none:
	...
	arc_breakpoint_kind_from_pc (struct gdbarch *gdbarch, CORE_ADDR *pcptr)
	{
	  size_t length_with_limm = gdb_insn_length (gdbarch, *pcptr);
	...
	which needs access to memory, and will consequently fail.

	Fix this in print_one_insn_test, in the default case, by iterating over
	supported osabi's to makes sure we trigger arc_linux_breakpoint_kind_from_pc
	which will give us a usable instruction to disassemble.

	Tested on x86_64-linux.

	The problem is that the test-case attempts to detect a change in the cb

	Fix this by first initializing to 0, and then changing the value to 12:
	...

	+  int cb = 0;
	+  cb = 12;

	and detecting that change.

	gdb: Do not add empty sections to the section map
	From: Ulrich Weigand <ulrich.weigand@de.ibm.com>

	build_objfile_section_table () creates four synthetic sections per
	objfile, which are collected by update_section_map () and passed to
	std::sort ().  When there are a lot of objfiles, for example, when
	debugging JITs, the presence of these sections slows down the sorting
	significantly.

	The output of update_section_map () is used by find_pc_section (),
	which can never return any of these sections: their size is 0, so they
	cannot be accepted by bsearch_cmp ().

	Filter them (and all the other empty sections) out in
	insert_section_p (), which is used only by update_section_map ().

	gas read_a_source_file #APP processing
	This fixes some horrible code using do_scrub_chars.  What we had ran
	text through do_scrub_chars twice, directly in read_a_source_file and
	again via the input_scrub_include_sb call.  That's silly, and since
	do_scrub_chars is a state machine, possibly wrong.  More silliness is
	evident in the temporary malloc'd buffer for do_scrub_chars output,
	which should have been written directly to sbuf.

	So, get rid of the do_scrub_chars call and support functions, leaving
	scrubbing to input_scrub_include_sb.  I did wonder about #NO_APP
	overlapping input_scrub_next_buffer buffers, but that should only
	happen if the string starts in one file and finishes in another.

	It is possible for sb_scrub_and_add_sb to not consume all of the input

	on a STM32F407-DISC0 board, but the upper 8 registers on Cortex-M33
	should be handled in the same way.

	The test consisted of running a program compiled with float-abi=hard.
	In the main function, a function taking a double as an argument was
	called. After the function call, a hardware timer was used to
	trigger an interrupt.

	In the debug session, a breakpoint was set in the function called
	from main to verify the content of the registers using "info float"
	and another breakpoint in the interrupt handler was used to check
	the same registers using "info float" on frame 2 (the frame just
	before the dummy frame created for the signal handler in gdb).

	Use unique_ptr for objfiles
	A while back, I changed objfiles to be held via a shared_ptr.  The
	idea at the time was that this was a step toward writing to the index
	cache in the background, and this would let gdb keep a reference alive
	to do so.  However, since then we've rewritten the DWARF reader, and
	the new index can do this without requiring a shared pointer -- in
	fact there are patches pending to implement this.

	This patch switches objfile management to unique_ptr, which makes more
	sense now.

	gdb, testsuite, fortran: fixup mixed-lang-stack for Intel/LLVM compilers
	When value-printing a pointer within GDB by default GDB will look for
	defined symbols residing at the address of the pointer.  For the given
	test the Intel/LLVM compiler stacks both display a symbol associated
	with a printed pointer while the gnu stack does not.  This leads to
	failures in the test when running the test with CC_FOR_TARGET='clang'
	CXX_FOR_TARGET='clang' F90_FOR_TARGET='flang'"

	  (gdb) b 37
	  (gdb) r
	  (gdb) f 6
	  (gdb) info args
	  a = 1
	  b = 2
	  c = 3
	  d = 4 + 5i
	  f = 0x419ed0 "abcdef"
	  g = 0x4041a0 <.BSS4>

	or CC_FOR_TARGET='icx' CXX_FOR_TARGET='icpx' F90_FOR_TARGET='ifx'"

	  c = 3
	  d = 4 + 5i
	  f = 0x52eee0 "abcdef"
	  g = 0x4ca210 <mixed_func_1a_$OBJ>

	For the compiled binary the Intel/LLVM compilers both decide to move the
	local variable g into the .bss section of their executable.  The gnu
	stack will keep the variable locally on the stack and not define a
	symbol for it.

	Since the behavior for Intel/LLVM is actually expected I adapted the
	testcase at this point to be a bit more allowing for other outputs.
	I added the optional "<SYMBOLNAME>" to the regex testing for g.

	The given changes reduce the test fails for Intel/LLVM stack by 4 each.

	since derived_type contains a heap allocated string and the copy
	constructor is not implemented it will only be able to shallow copy the
	object.  Right after each of the functions the object gets freed - on the
	other hand the d'tor of derived_type actually is implemented and calls
	free on the heap allocated string which leads to a double free.  Instead
	of obeying the rule of 3/5 I just got rid of all that since it does not
	serve the test.  The string is now just a const char* = ".." object
	member.

	testsuite, fortran: allow additional completions in module.exp
	For ifort, ifx, and flang the tests "complete modm" and "complete
	modmany" fail.  This is because all three emit additional completion
	suggestions.  These additional suggestions have their origin in symbols
	emitted by the compilers which can also be completed from the respective
	incomplete word (modm or modmany).  For this specific example gfortran
	does not emit any additional symbols.

	For example, in this test the linkage name for var_a in ifx is
	"modmany_mp_var_a_" while gfortran uses "__modmany_MOD_var_a" instead.
	Since modmany_mp_var_a can be completed from modm and also modmany they
	will get displayed, while gfortran's symbol starts with "__" and thus will
	be ignored (it cannot be a completion of a word starting with "m").

	Similar things happen in flang and ifort.  Some example output is shown
	below:

	FLANG
	  (gdb) complete p modm
	  p modmany
	  p modmany::var_a
	  p modmany::var_b
	  p modmany::var_c
	  p modmany::var_i
	  p modmany_

	IFX/IFORT
	  (gdb) complete p modm
	  p modmany
	  p modmany._
	  p modmany::var_a
	  p modmany::var_b
	  p modmany::var_c
	  p modmany::var_i
	  p modmany_mp_var_a_
	  p modmany_mp_var_b_
	  p modmany_mp_var_c_
	  p modmany_mp_var_i_

	GFORTRAN
	  (gdb) complete p modm
	  p modmany
	  p modmany::var_a
	  p modmany::var_b
	  p modmany::var_c
	  p modmany::var_i

	I want to emphasize: for Fortran (and also C/C++) the complete command
	does not actually check whether its suggestions make sense - all it does
	is look for any symbol (in the minimal symbols, partial symbols etc.)
	that a given substring can be completed to (meaning that the given substring
	is the beginning of the symbol).  One can easily produce a similar
	output for the gfortran compiled executable.  For this look at the
	slightly modified "complete p mod" in gfortran:

	  (gdb) complete p mod
	  p mod1
	  p mod1::var_const
	  ...
	  p mod_1.c
	  p modcounter
	  p mode_t
	  p modf
	  ...
	  p modify_ldt
	  p modmany
	  p modmany::var_a
	  p modmany::var_b
	  p modmany::var_c
	  p modmany::var_i
	  p module
	  p module.f90
	  p module_entry
	  p moduse
	  p moduse::var_x
	  p moduse::var_y

	Many of the displayed symbols do not actually work with print:

	  (gdb) p mode_t
	  Attempt to use a type name as an expression
	  (gdb) p mod_1.c
	  No symbol "mod_1" in current context.
	  (gdb)

	I think that in the given test the output for gfortran only looks nice
	"by chance" rather than is actually expected.  Expected is any output
	that also contains the completions

	  p modmany

	  p modmany::var_a
	  p modmany::var_b
	  p modmany::var_c
	  p modmany::var_i

	while anythings else can be displayed as well (depending on the
	compiler and its emitted symbols).

	This, I'd consider all three outputs as valid and expected - one is just
	somewhat lucky that gfortran does not produce any additional symbols that
	got matched.

	The given patch improves test performance for all three compilers
	by allowing additional suggested completions inbetween and after
	the two given blocks in the test.  I did not allow additional print
	within the modmany_list block since the output is ordered alphabetically
	and there should normally not appear any additional symbols there.

	For flang/ifx/ifort I each see 2 failures less (which are exactly the two
	complete tests).

	As a side note and since I mentioned C++ in the beginning: I also tried
	the gdb.cp/completion.exp.  The output seems a bit more reasonable,
	mainly since C++ actually has a demangler in place and linkage symbols
	do not appear in the output of complete.  Still, with a poor enough
	to-be-completed string one can easily produce similar results:

	  (gdb) complete p t
	  ...
	  p typeinfo name for void
	  p typeinfo name for void const*
	  p typeinfo name for void*
	  p typeinfo name for wchar_t
	  p typeinfo name for wchar_t const*
	  p typeinfo name for wchar_t*
	  p t *** List may be truncated, max-completions reached. ***
	  (gdb) p typeinfo name for void*
	  No symbol "typeinfo" in current context.
	  (gdb) complete p B
	  p BACK_SLASH
	  p BUF_FIRST
	  p BUF_LAST
	  ...
	  p Base
	  p Base::Base()
	  p Base::get_foo()
	  p bad_key_err
	  p buf
	  p buffer
	  p buffer_size
	  p buflen
	  p bufsize
	  p build_charclass.isra
	  (gdb) p bad_key_err
	  No symbol "bad_key_err" in current context.

	(compiled with gcc/g++ and breaking at main).

	This patch is only about making the referenced test more 'fair' for the
	other compilers.  Generally, I find the behavior of complete a bit
	confusing and maybe one wants to change this at some point but this
	would be a bigger task.

2022-05-31  Nils-Christian Kempke  <nils-christian.kempke@intel.com>

	testsuite, fortran: fix info-types for intel compilers
	This info-types.exp test case had a few issues that this patch fixes.

	First, the emitted symbol character(kind=1)/character*1 (different
	compilers use different naming converntions here) which is checkedin the
	test is not actually expected given the test program.  There is no
	variable of that type in the test.  Still, gfortran emits it for every
	Fortran program there is.  The reason is the way gfortran handles Fortran's
	named main program.  It generates a wrapper around the Fortran program
	that is quite similar to a C main function.  This C-like wrapper has
	argc and argv arguments for command line argument passing and the argv
	pointer type has a base type character(kind=1) DIE emitted at CU scope.

	Given the program

	  program prog
	  end program prog

	the degbug info gfortran emits looks somewhat like

	   <0><c>: Abbrev Number: 3 (DW_TAG_compile_unit)
	      ...
	   <1><2f>: Abbrev Number: 4 (DW_TAG_subprogram)
	      <30>   DW_AT_external    : 1
	      <30>   DW_AT_name        : (indirect string, ...): main
	      ...
	   <2><51>: Abbrev Number: 1 (DW_TAG_formal_parameter)
	      <52>   DW_AT_name        : (indirect string, ...): argc
	      ...
	   <2><5d>: Abbrev Number: 1 (DW_TAG_formal_parameter)
	      <5e>   DW_AT_name        : (indirect string, ...): argv
	      ...
	      <62>   DW_AT_type        : <0x77>
	      ...
	   <2><6a>: Abbrev Number: 0
	   ...
	   <1><77>: Abbrev Number: 6 (DW_TAG_pointer_type)
	      <78>   DW_AT_byte_size   : 8
	      <79>   DW_AT_type        : <0x7d>
	   <1><7d>: Abbrev Number: 2 (DW_TAG_base_type)
	      <7e>   DW_AT_byte_size   : 1
	      <7f>   DW_AT_encoding    : 8        (unsigned char)
	      <80>   DW_AT_name        : (indirect string, ...): character(kind=1)
	   <1><84>: Abbrev Number: 7 (DW_TAG_subprogram)
	      <85>   DW_AT_name        : (indirect string, ...): prog
	   ...

	Ifx and flang do not emit any debug info for a wrapper main method so
	the type is missing here.  There was the possibility of actually adding
	a character*1 type variable to the Fortran executable, but both, ifx and
	gfortran chose to emit this variable's type as a DW_TAG_string_type of
	length one (instead of a character(kind=1), or whatever the respective
	compiler naming convention is).  While string types are printed as
	character*LENGHT in the fortran language part (e.g. when issuing a
	'ptype') they do not generate any symbols inside GDB.  In read.c it says

	   /* These dies have a type, but processing them does not create
	      a symbol or recurse to process the children.  Therefore we can
	      read them on-demand through read_type_die.  */

	So they did not add any output to 'info types'.  Only flang did emit a
	character type here.
	As adding a type would have a) not solved the problem for ifx and would
	have b) somehow hidden the curious behavior of gfortran, instead, the
	check for this character type was chagened to optional with the
	check_optional_entry to allow for the symbols's absence and to allow
	flang and ifx to pass this test as well.

	Second, the line checked for s1 was hardcoded as 37 in the test.  Given
	that the type is actually defined on line 41 (which is what is emitted by
	ifx) it even seems wrong.  The line check for s1 was changed to actually
	check for 41 and a gfortran bug has been filed here

	   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105454

	The test is now marked as xfail for gfortran.

	Third, the whole test of checking for the 'Type s1' in info types seemed
	questionable.  The type s1 is declared iside the scope of the Fortran
	program info_types_test.  Its DIE however is emitted as a child of the
	whole compilation unit making it visible outside of the program's scope.
	The 'info types' command checks for types stored in the GLOBAL_BLOCK,
	or STATIC_BLOCKm wgucm according to block.h

	   The GLOBAL_BLOCK contains all the symbols defined in this compilation
	   whose scope is the entire program linked together.
	   The STATIC_BLOCK contains all the symbols whose scope is the
	   entire compilation excluding other separate compilations.

	so for gfortran, the type shows up in the output of 'info types'.  For
	flang and ifx on the other hand this is not the case.  The two compilers
	emit the type (correctly) as a child of the Fortran program, thus not
	adding it to either, the GLOBAL_BLOCK nor the LOCAL_BLOCK.  A bug has
	been opened for the gfortran scoping issue:

	   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105454

	While the most correct change might have been removing the check for s1,
	the change made here was to only check for this type in case of gfortran
	being used as the compiler, as this check also covers the declaration
	line issue mentioned above.  A comment was added to maybe remove this
	check once the scoping issue is resolved (and it starts to fail with
	newer gfortran versions).  The one used to test these changes was 13.0.

	testsuite/lib: add check_optional_entry for GDBInfoSymbols
	There was already a similar functionality for the GDBInfoModuleSymbols.
	This just extends the GDBInfoSymbols.  We will use this feature in a
	later commit to make a testcase less GNU specific and more flexible for
	other compilers.

	Namely, in gdb.fortran/info-types.exp currenlty
	GDBInfoSymbols::check_entry is used to verify and test the output of the
	info symbols command.  The test, however was written with gfortran as a
	basis and some of the tests are not fair with e.g. ifx and ifort as
	they test for symbols that are not actually required to be emitted.  The
	lines
	   GDBInfoSymbols::check_entry "${srcfile}" "" "${character1}"
	and
	   GDBInfoSymbols::check_entry "${srcfile}" "37" "Type s1;"

	check for types that are either not used in the source file (character1)
	or should not be emitted by the compiler at global scope (s1) thus no
	appearing in the info symbols command.  In order to fix this we will
	later use the newly introduced check_optional_entry over check_entry.

	a bug and there is an open gcc ticket for this here:

	   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=50377

	Adding the keyword does not change the gfortran compiling of the example.
	It will, however, prevent a future fail once 50377 has been addressed.

	    Nils-Christian Kempke  <nils-christian.kempke@intel.com>

	gdb/testsuite: add Fortran compiler identification to GDB
	This commit adds a separate Fortran compiler identification mechanism to
	the testsuite, similar to the existing one for C/C++.  Before this
	change, the options and version for the Fortran compiler specified when
	running the testsuite with F90_FOR_TARGET set, was detected via its
	respective C compiler.  So running the testsuite as

	  make check TEST=gdb.fortran/*.exp CC_FOR_TARGET=gcc F90_FOR_TARGET=ifx

	or even

	  make check TEST=gdb.fortran/*.exp F90_FOR_TARGET=ifx

	would use the gcc compiler inside the procedures get_compiler_info and
	test_compiler_info to identify compiler flags and the compiler version.
	This could sometimes lead to unpredictable outputs.  It also limited
	testsuite execution to combinations where C and Fortran compiler would
	come from the same family of compiers (gcc/gfortran, icc/ifort, icx/ifx,
	clang/flang ..).  This commit enables GDB to detect C and Fortran
	compilers independently of each other.

	As most/nearly all Fortran compilers have a mechanism for preprocessing
	files in a C like fashion we added the exact same meachnism that already
	existed for C/CXX.  We let GDB preprocess a file with the compilers
	Fortran preprocessor and evaluate the preprocessor defined macros in that
	file.

	This enables GDB to properly run heterogeneous combinations of C and
	Fortran compilers such as

	  CC_FOR_TARGET='gcc' and F90_FOR_TARGET='ifort'

	or enables one to run the testsuite without specifying a C compiler as in

	  make check TESTS=gdb.fortran/*.exp F90_FOR_TARGET='ifx'
	  make check TESTS=gdb.fortran/*.exp F90_FOR_TARGET='flang'

	On the other hand this also requires one to always specify a
	identification mechanism for Fortran compilers in the compiler.F90 file.

	We added identification for GFORTRAN, FLANG (CLASSIC and LLVM) IFX,
	IFORT, and ARMFLANG for now.

	Classic and LLVM flang were each tested with their latest releases on
	their respective release pages.  Both get recognized by the new compiler
	identification and we introduced the two names flang-classic and
	flang-llvm to distinguish the two.  While LLVM flang is not quite mature
	enough yet for running the testsuite we still thought it would be a good
	idea to include it already.  For this we added a case for the fortran_main
	procedure.  LLVM flang uses 'MAIN__' as opposed to classic flang which
	uses 'MAIN_' here.

	We did not have the possibility to test ARMFLANG - the versioning scheme
	here was extracted from its latest online documentation.

	We changed the test_compiler_info procedure to take another optional
	argument, the language string, which will be passed though to the
	get_compiler_info procedure.  Passing 'f90' or 'c++' here will then
	trigger the C++/Fortran compiler identification within
	get_compiler_info.  The latter procedure was extended to also handle
	the 'f90' argument (similarly to the already existing 'c++' one).

2022-05-31  Nils-Christian Kempke  <nils-christian.kempke@intel.com>

	gdb/testsuite: move getting_compiler_info to front of gdb_compile
	The procedure gdb_compile queries its options via

	   [lsearch -exact $options getting_compiler_info]

	to check whether or not it was called in with the option
	getting_compiler_info.  If it was called with this option it would
	preprocess some test input to try and figure out the actual compiler
	version of the compiler used.  While doing this we cannot again try to
	figure out the current compiler version via the 'getting_compiler_info'
	option as this would cause infinite recursion.  As some parts of the
	procedure do recursively test for the compiler version to e.g. set
	certain flags, at several places gdb_compile there are checks for the
	getting_compiler_info option needed.

	In the procedure, there was already a variable 'getting_compiler_info'
	which was set to the result of the 'lsearch' query and used instead of
	again and again looking for getting_compiler_info in the procedure
	options.  But, this variable was actually set too late within the code.
	This lead to a mixture of querying 'getting_compiler_info' or
	doing an lserach on the options passed to the procedure.

	I found this inconsistent and instead moved the variable
	getting_compiler_info to the front of the procedure.  It is set to true
	or false depending on whether or not the argument is found in the
	procedure's options (just as before) and queried instead of doing an
	lsearch on the procedure options in the rest of the procedure.

	The last uses of the F77_FOR_TARGET via passing f77 to GDB's compile
	procedure were removed in this commit

	   commit 0ecee54cfd04a60e7ca61ae07c72b20e21390257
	   Author: Tom Tromey <tromey@redhat.com>
	   Date:   Wed Jun 29 17:50:47 2011 +0000

	over 10 years ago.  The last .f files in the testsuite by now are all
	being compiled by passing 'f90' to the GDB compile, thus only actually
	using F90_FOR_TARGET (array-element.f, block-data.f, subarray.f).
	Gfortran in this case is backwards compatible with most f77 code as
	claimed on gcc.gnu.org/fortran.

	The reason we'd like to get rid of this now is, that we'll be
	implementing a Fortran compiler identification mechanism, similar to the
	C/Cpp existing ones.  It would be using the Fortran preprocessor macro
	defines to identify the Fortran compiler version at hand.  We found it
	inconsequent to only implement this for f90 but, on the other hand, f77
	seems deprecated.  So, with this commit we remove the remaining lines for
	its support.

	  202be274a41a ("opcodes/i386: remove trailing whitespace from insns with zero operands")

	causes this regression:

	  FAIL: gdb.trace/signal.exp: find syscall insn in kill

	It's because the test still expects to match a whitespace after the

	gdb/manual: Introduce location specs
	The current "Specify Location" section of the GDB manual starts with:

	 "Several @value{GDBN} commands accept arguments that specify a location
	 of your program's code."

	And then, such commands are documented as taking a "location"
	argument.  For example, here's a representative subset:

	 @item break @var{location}
	 @item clear @var{location}
	 @item until @var{location}
	 @item list @var{location}
	 @item edit @var{location}
	 @itemx info line @var{location}
	 @item info macros @var{location}
	 @item trace @var{location}
	 @item info scope @var{location}
	 @item maint agent @r{[}-at @var{location}@r{,}@r{]} @var{expression}

	The issue here is that "location" isn't really correct for most of
	these commands.  Instead, the "location" argument is really a
	placeholder that represent an umbrella term for all of the
	"linespecs", "explicit location", and "address location" input
	formats.  GDB parses these and then finds the actual code locations
	(plural) in the program that match.  For example, a "location"
	specified like "-function func" will actually match all the code
	locations in the program that correspond to the address/file/lineno of
	all the functions named "func" in all the loaded programs and shared
	libraries of all the inferiors.  A location specified like "-function
	func -label lab" matches all the addresses of C labels named "lab" in
	all functions named "func".  Etc.

	This means that several of the commands that claim they accept a
	"location", actually end up working with multiple locations, and the
	manual doesn't explain that all that well.  In some cases, the command
	will work with all the resolved locations.  In other cases, the
	command aborts with an error if the location specification resolves to
	multiple locations in the program.  In other cases, GDB just
	arbitrarily and silently picks whatever is the first resolved code
	location (which sounds like should be improved).

	To clarify this, I propose we use the term "Location Specification",
	with shorthand "locaction spec", when we're talking about the user
	input, the argument or arguments that is/are passed to commands to
	instruct GDB how to find locations of interest.  This is distinct from
	the actual code locations in the program, which are what GDB finds
	based on the user-specified location spec.  Then use "location
	specification or the shorter "location spec" thoughout instead of
	"location" when we're talking about the user input.

	Thus, this commit does the following:

	- renames the "Specify Location" section of the manual to "Location
	  Specifications".

	- It then introduces the term "Location Specification", with
	  corresponding shorthand "location spec", as something distinct from
	  an actual code location in the program.  It explains what a concrete
	  code location is.  It explains that a location specification may be
	  incomplete, and that may match multiple code locations in the
	  program, or no code location at all.  It gives examples.  Some
	  pre-existing examples were moved from the "Set Breaks" section, and
	  a few new ones that didn't exist yet were added.  I think it is
	  better to have these centralized in this "Location Specification"
	  section, since all the other commands that accept a location spec
	  have an xref that points there.

	- Goes through the manual, and where "@var{location}" was used for a
	  command argument, updated it to say "@var{locspec}" instead.  At the
	  same time, tweaks the description of the affected commands to
	  describe what happens when the location spec resolves to more than
	  one location.  Most commands just did not say anything about that.

	  One command -- "maint agent -at @var{location}" -- currently says it
	  accepts a "location", suggesting it can accept address and explicit
	  locations too, but that's incorrect.  In reality, it only accepts
	  linespecs, so fix it accordingly.

	  One MI command -- "-trace-find line" -- currently says it accepts a
	  "line specification", but it can accept address and explicit
	  locations too, so fix it accordingly.

	Special thanks goes to Eli Zaretskii for reviews and rewording
	suggestions.

	gdb/python: improve formatting of help text for user defined commands
	Consider this command defined in Python (in the file test-cmd.py):

	  class test_cmd (gdb.Command):
	    """
	    This is the first line.
	      Indented second line.
	    This is the third line.
	    """

	    def __init__ (self):
	      super ().__init__ ("test-cmd", gdb.COMMAND_OBSCURE)

	    def invoke (self, arg, from_tty):
	      print ("In test-cmd")

	  test_cmd()

	Now, within a GDB session:

	  (gdb) source test-cmd.py
	  (gdb) help test-cmd

	    This is the first line.
	      Indented second line.
	    This is the third line.

	  (gdb)

	I think there's three things wrong here:

	  1. The leading blank line,
	  2. The trailing blank line, and
	  3. Every line is indented from the left edge slightly.

	The problem of course, is that GDB is using the Python doc string
	verbatim as its help text.  While the user has formatted the help text
	so that it appears clear within the .py file, this means that the text
	appear less well formatted when displayed in the "help" output.

	The same problem can be observed for gdb.Parameter objects in their
	set/show output.

	In this commit I aim to improve the "help" output for commands and
	parameters.

	To do this I have added gdbpy_fix_doc_string_indentation, a new
	function that rewrites the doc string text following the following
	rules:

	  1. Leading blank lines are removed,
	  2. Trailing blank lines are removed, and
	  3. Leading whitespace is removed in a "smart" way such that the
	  relative indentation of lines is retained.

	With this commit in place the above example now looks like this:

	  (gdb) source ~/tmp/test-cmd.py
	  (gdb) help test-cmd
	  This is the first line.
	    Indented second line.
	  This is the third line.
	  (gdb)

	Which I think is much neater.  Notice that the indentation of the
	second line is retained.  Any blank lines within the help text (not
	leading or trailing) will be retained.

	I've added a NEWS entry to note that there has been a change in
	behaviour, but I didn't update the manual.  The existing manual is
	suitably vague about how the doc string is used, so I think the new
	behaviour is covered just as well by the existing text.

2022-05-28  Andrew Burgess  <aburgess@redhat.com>

	gdb: use gdb::unique_xmalloc_ptr<char> for docs in cmdpy_init
	Make use of gdb::unique_xmalloc_ptr<char> to hold the documentation
	string in cmdpy_init (when creating a custom GDB command in Python).
	I think this is all pretty straight forward, the only slight weirdness
	is the removal of the call to free toward the end of this function.

	Prior to this commit, if an exception was thrown after the GDB command
	was created then we would (I think) end up freeing the documentation
	string even though the command would remain registered with GDB, which
	would surely lead to undefined behaviour.

	After this commit we release the doc string at the point that we hand
	it over to the command creation routines.  If we throw _after_ the
	command has been created within GDB then the doc string will be left
	live.  If we throw during the command creation itself (either from
	add_prefix_cmd or add_cmd) then it is up to those functions to free
	the doc string (I suspect we don't, but I think in general the
	commands are pretty bad at cleaning up after themselves, so I don't
	think this is a huge problem).

	opcodes/i386: remove trailing whitespace from insns with zero operands
	While working on another patch[1] I had need to touch this code in
	i386-dis.c:

	  ins->obufp = ins->mnemonicendp;
	  for (i = strlen (ins->obuf) + prefix_length; i < 6; i++)
	    oappend (ins, " ");
	  oappend (ins, " ");
	  (*ins->info->fprintf_styled_func)
	    (ins->info->stream, dis_style_mnemonic, "%s", ins->obuf);

	What this code does is add whitespace after the instruction mnemonic
	and before the instruction operands.

	The problem I ran into when working on this code can be seen by
	assembling this input file:

	    .text
	    nop
	    retq

	Now, when I disassemble, here's the output.  I've replaced trailing
	whitespace with '_' so that the issue is clearer:

	    Disassembly of section .text:

	    0000000000000000 <.text>:
	       0:	90                   	nop
	       1:	c3                   	retq___

	Notice that there's no trailing whitespace after 'nop', but there are
	three spaces after 'retq'!

	What happens is that instruction mnemonics are emitted into a buffer
	instr_info::obuf, then instr_info::mnemonicendp is setup to point to
	the '\0' character at the end of the mnemonic.

	When we emit the whitespace, this is then added starting at the
	mnemonicendp position.  Lets consider 'retq', first the buffer is
	setup like this:

	  'r' 'e' 't' 'q' '\0'

	Then we add whitespace characters at the '\0', converting the buffer
	to this:

	  'r' 'e' 't' 'q' ' ' ' ' ' ' '\0'

	However, 'nop' is actually an alias for 'xchg %rax,%rax', so,
	initially, the buffer is setup like this:

	  'x' 'c' 'h' 'g' '\0'

	Then in NOP_Fixup we spot that we have an instruction that is an alias
	for 'nop', and adjust the buffer to this:

	  'n' 'o' 'p' '\0' '\0'

	The second '\0' is left over from the original buffer contents.
	However, when we rewrite the buffer, we don't afjust mnemonicendp,
	which still points at the second '\0' character.

	Now, when we insert whitespace we get:

	  'n' 'o' 'p' '\0' ' ' ' ' ' ' ' ' '\0'

	Notice the whitespace is inserted after the first '\0', so, when we
	print the buffer, the whitespace is not printed.

	The fix for this is pretty easy, I can change NOP_Fixup to adjust
	mnemonicendp, but now a bunch of tests start failing, we now produce
	whitespace after the 'nop', which the tests don't expect.

	So, I could update the tests to expect the whitespace....

	...except I'm not a fan of trailing whitespace, so I'd really rather
	not.

	Turns out, I can pretty easily update the whitespace emitting code to
	spot instructions that have zero operands and just not emit any
	whitespace in this case.  So this is what I've done.

	I've left in the fix for NOP_Fixup, I think updating mnemonicendp is
	probably a good thing, though this is not really required any more.

	I've then updated all the tests that I saw failing to adjust the
	expected patterns to account for the change in whitespace.

	Replace bfd_hostptr_t with uintptr_t

	or a pointer.  It mostly appears in the coff backend code in casts.
	include/coff/internal.h struct internal_syment and union
	internal_auxent have the only uses in data structures, where
	comparison with include/coff/external.h and other code reveals that
	the type only needs to be large enough for a 32-bit integer or a
	pointer.  That should mean replacing with uintptr_t is OK.

	Remove much of BFD_HOST configury
	This patch removes the definition of bfd_uint64_t and bfd_int64_t as
	well as most BFD_HOST_* which are now unused.

	Remove use of bfd_uint64_t and similar

	BFD_HOST_64_BIT.  This patch does that, removes #ifdef BFD_HOST_*
	and tidies a few places that print 64-bit values.

	gdb: Change psymbol_functions::require_partial_symbols to partial_symbols
	The previous patch ensured that partial symbols are read before calling
	most of the quick_function's methods.

	The psymbol_functions class has the require_partial_symbols method which
	serves this exact purpose, and does not need to do it anymore.

	This patch renames this method to partial_symbols and makes it an accessor
	which asserts that partial symbols have been read at this point.

	Regression tested on x86_64-linux.

	gdb: Require psymtab before calling quick_functions in objfile
	The recent DWARF indexer rewrite introduced a regression when debugging
	a forking program.

	Here is a way to reproduce the issue (there might be other ways, but one
	is enough and this one mimics the situation we encountered).  Consider a
	program which forks, and the child loads a shared library and calls a
	function in this shared library:

	    if (fork () == 0)
	      {
	        void *solib = dlopen (some_solib, RTLD_NOW);
	        void (*foo) () = dlsym (some_solib, "foo");
	        foo ();
	      }

	Suppose that this program is compiled without debug info, but the shared
	library it loads has debug info enabled.

	When debugging such program with the following options:

	  - set detach-on-fork off
	  - set follow-fork-mode child

	we see something like:

	    (gdb) b foo
	    Function "foo" not defined.
	    Make breakpoint pending on future shared library load? (y or [n]) y
	    Breakpoint 1 (foo) pending.
	    (gdb) run
	    Starting program: a.out
	    [Attaching after process 19720 fork to child process 19723]
	    [New inferior 2 (process 19723)]
	    [Switching to process 19723]

	    Thread 2.1 "a.out" hit Breakpoint 1, 0x00007ffff7fc3101 in foo () from .../libfoo.so
	    (gdb) list

	    ---------------------
	    A fatal error internal to GDB has been detected, further
	    debugging is not possible.  GDB will now terminate.

	    This is a bug, please report it.  For instructions, see:
	    <https://www.gnu.org/software/gdb/bugs/>.

	The first issue observed is in the message printed when hitting the
	breakpoint.  It says that there was a break in the .so file as if there
	was no debug info associated with it, but there is.  Later, if we try to
	display the source where the execution stopped, we have a segfault.

	Note that not having the debug info on the main binary is not strictly
	required to encounter some issues, it only is to encounter the segfault.
	If the main binary has debug information, GDB shows some source form the
	main binary, unrelated to where we stopped.

	The core of the issue is that GDB never loads the psymtab for the
	library.  It is not loaded when we first see the .so because in case of
	detach-on-fork off, follow-fork-mode child, infrun.c sets
	child_inf->symfile_flags = SYMFILE_NO_READ to delay the psymtab loading
	as much as possible.  If we compare to what was done to handle this
	before the new indexer was activated, the psymatb construction for the
	shared library was done under
	psymbol_functions::expand_symtabs_matching:

	    bool
	    psymbol_functions::expand_symtabs_matching (...)
	    {
	        for (partial_symtab *ps : require_partial_symbols (objfile))
	        ...
	    }

	The new indexer's expand_symtabs_matching callback does not have a call
	to the objfile's require_partial_symbols, so if the partial symbol table
	is not loaded at this point, there is no mechanism to fix this.

	Instead of requiring each implementation of the quick_functions to check
	that partial symbols have been read, I think it is safer to enforce this
	when calling the quick functions.  The general pattern for calling the
	quick functions is:

	    for (auto *iter : qf)
	      iter->the_actual_method_call (...)

	This patch proposes to wrap the access of the `qf` field with an accessor
	which ensures that partial symbols have been read before iterating:
	qf_require_partial_symbols.  All calls to quick functions are updated
	except:

	- quick_functions::dump
	- quick_functions::read_partial_symbols (from
	  objfile::require_partial_symbols)
	- quick_functions::can_lazily_read_symbols and quick_functions::has_symbols
	  (from objfile::has_partial_symbols)

	Regression tested on x86_64-gnu-linux.

	Fix crash in new DWARF indexer
	PR gdb/29128 points out a crash in the new DWARF index code.  This
	happens if the aranges for a CU claims a PC, but the symtab that is
	created during CU expansion does not actually contain the PC.  This
	can only occur due to bad debuginfo, but at the same time, gdb should
	not crash.

	This patch fixes the bug and further merges some code into
	dwarf2_base_index_functions.  This merger helps prevent the same issue
	from arising from the other index implementations.

	Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29128

2022-05-26  Tom Tromey  <tromey@adacore.com>

	Finalize each cooked index separately
	After DWARF has been scanned, the cooked index code does a
	"finalization" step in a worker thread.  This step combines all the
	index entries into a single master list, canonicalizes C++ names, and
	splits Ada names to synthesize package names.

	While this step is run in the background, gdb will wait for the
	results in some situations, and it turns out that this step can be
	slow.  This is PR symtab/29105.

	This can be sped up by parallelizing, at a small memory cost.  Now
	each index is finalized on its own, in a worker thread.  The cost
	comes from name canonicalization: if a given non-canonical name is
	referred to by multiple indices, there will be N canonical copies (one
	per index) rather than just one.

	This requires changing the users of the index to iterate over multiple
	results.  However, this is easily done by introducing a new "chained
	range" class.

	When run on gdb itself, the memory cost seems rather low -- on my
	current machine, "maint space 1" reports no change due to the patch.

	For performance testing, using "maint time 1" and "file" will not show
	correct results.  That approach measures "time to next prompt", but
	because the patch only affects background work, this shouldn't (and
	doesn't) change.  Instead, a simple way to make gdb wait for the
	results is to set a breakpoint.

	Before:

	    $ /bin/time -f%e ~/gdb/install/bin/gdb -nx -q -batch \
	        -ex 'break main' /tmp/gdb
	    Breakpoint 1 at 0x43ec30: file ../../binutils-gdb/gdb/gdb.c, line 28.

	 arm: avoid use of GNU builtin function in s_arm_unwind_save_mixed
	Whilst reviewing Luis' proposed change to s_arm_unwind_save_mixed
	yesterday I noticed that we were making use of __builting_clzl
	directly within the main function, which is not guaranteed to be
	portable.  Whilst studying the code further, I also realized that it
	could be rewritten without using it and also reworked to remove a lot
	of unnecessary iterations steps.  So this patch does that (and also
	removes the source of the warning that Luis was trying to fix).
	Finally, with the rewrite we can also simplify the caller of this
	routine as the new version can handle all the cases directly.

		* config/tc-arm.c (s_arm_unwind_save_mixed): Rewrite without
		using __builtin_clzl.
		(s_arm_unwind_save): Simplify logic for simple/mixed register saves.

	gdb/linux-nat: xfer_memory_partial return E_IO on error
	When accessing /proc/PID/mem, if pread64/pwrite64/read/write encounters
	an error and return -1, linux_proc_xfer_memory_partial return
	TARGET_XFER_EOF.

	I think it should return TARGET_XFER_E_IO in this case.  TARGET_XFER_EOF
	is returned when pread64/pwrite64/read/frite returns 0, which indicates
	that the address space is gone and the whole process has exited or
	execed.

	This patch makes this change.

	gdb/testsuite: prefer gdb_test in gdb.dwarf2/calling-convention
	Since ed01945057c "Make gdb_test's question non-optional if specified",
	if the question and response parameters are given to gdb_test, the
	framework enforces that GDB asks the question.  Before this patch, tests
	needed to use gdb_test_multiple to enforce this.

	This patch updates the gdb.dwarf2/calling-convention.exp testcase to use
	gdb_test to check that GDB asks a question.  This replaces the more
	complicated gdb_test_multiple based implementation.

	Tested on x86_64-gnu-linux.

	Show enabled locations with disabled breakpoint parent as "y-"
	Currently, breakpoint locations that are enabled while their parent
	breakpoint is disabled are displayed with "y" in the Enb colum of
	"info breakpoints":

	 (gdb) info breakpoints
	 Num     Type           Disp Enb Address            What
	 1       breakpoint     keep n   <MULTIPLE>
	 1.1                         y   0x00000000000011b6 in ...
	 1.2                         y   0x00000000000011c2 in ...
	 1.3                         n   0x00000000000011ce in ...

	Such locations won't trigger a break, so to avoid confusion, show "y-"
	instead.  For example:

	 (gdb) info breakpoints
	 Num     Type           Disp Enb Address            What
	 1       breakpoint     keep n   <MULTIPLE>
	 1.1                         y-  0x00000000000011b6 in ...
	 1.2                         y-  0x00000000000011c2 in ...
	 1.3                         n   0x00000000000011ce in ...

	The "-" sign is inspired on how the TUI represents breakpoints on the
	left side of the source window, with "b-" for a disabled breakpoint.

	gdb: Fix DUPLICATE and PATH regressions throughout
	The previous patch to add -prompt/-lbl to gdb_test introduced a
	regression: Before, you could specify an explicit empty message to
	indicate you didn't want to PASS, like so:

	  gdb_test COMMAND PATTERN ""

	After said patch, gdb_test no longer distinguishes
	no-message-specified vs empty-message, so tests that previously would
	be silent on PASS, now started emitting PASS messages based on
	COMMAND.  This in turn introduced a number of PATH/DUPLICATE
	violations in the testsuite.

	This commit fixes all the regressions I could see.

	This patch uses the new -nopass feature introduced in the previous
	commit, but tries to avoid it if possible.  Most of the patch fixes
	DUPLICATE issues the usual way, of using with_test_prefix or explicit
	unique messages.

	See previous commit's log for more info.

	In addition to looking for DUPLICATEs, I also looked for cases where
	we would now end up with an empty message in gdb.sum, due to a
	gdb_test being passed both no message and empty command.  E.g., this
	in gdb.ada/bp_reset.exp:

	 gdb_run_cmd
	 gdb_test "" "Breakpoint $decimal, foo\\.nested_sub \\(\\).*"

	was resulting in this in gdb.sum:

	 PASS: gdb.ada/bp_reset.exp:

	I fixed such cases by passing an explicit message.  We may want to
	make such cases error out.

	Tested on x86_64 GNU/Linux, native and native-extended-gdbserver.  I
	see zero PATH cases now.  I get zero DUPLICATEs with native testing
	now.  I still see some DUPLICATEs with native-extended-gdbserver, but
	those were preexisting, unrelated to the gdb_test change.

	Add -nopass option to gdb_test/gdb_test_multiple
	The previous patch to add -prompt/-lbl to gdb_test introduced a
	regression: Before, you could specify an explicit empty message to
	indicate you didn't want to PASS, like so:

	  gdb_test COMMAND PATTERN ""

	After said patch, gdb_test no longer distinguishes
	no-message-specified vs empty-message, so tests that previously would
	be silent on PASS, now started emitting PASS messages based on
	COMMAND.  This in turn introduced a number of PATH/DUPLICATE
	violations in the testsuite.

	I think that not issuing a PASS should be restricted to only a few
	cases -- namely in shared routines exported by gdb.exp, which happen
	to use gdb_test internally.  In tests that iterate an unknown number
	of tests exercising some racy scenario.  In the latter case, if we
	emit PASSes for each iteration, we run into the situation where
	different testsuite runs emit a different number of PASSes.

	Thus, this patch preserves the current behavior, and, instead, adds a
	new "-nopass" option to gdb_test and gdb_test_no_output.  Compared to
	the old way of supressing PASS with an empty message, this has the
	advantage that you can specify a FAIL message that is distinct from
	the command string, and, it's also more explicit.

	field present in binutils sources. Also, per 1.6.2, BC has the same

	[gdb/testsuite] Fix gdb.opt/clobbered-registers-O2.exp with clang
	When running test-case gdb.opt/clobbered-registers-O2.exp with clang 12.0.1, I
	get:
	...
	(gdb) run ^M
	Starting program: clobbered-registers-O2 ^M
	^M
	Program received signal SIGSEGV, Segmentation fault.^M
	gen_movsd (operand0=<optimized out>, operand1=<optimized out>) at \
	  clobbered-registers-O2.c:31^M
	31              return *start_sequence(operand0, operand1);^M
	(gdb) FAIL: gdb.opt/clobbered-registers-O2.exp: runto: run to start_sequence
	...

	The problem is that the breakpoint in start_sequence doesn't trigger, because:
	- the call to start_sequence in gen_movsd is optimized away, despite the
	  __attribute__((noinline)), so the actual function start_sequence doesn't get
	  called, and
	- the debug info doesn't contain inlined function info, so there's only one
	  breakpoint location.

	Adding noclone and noipa alongside the noinline attribute doesn't fix this.

	Adding the clang-specific attribute optnone in start_sequence does, but since
	it inhibits all optimization, that's not a preferred solution in a gdb.opt
	test-case, and it would work only for clang and not other compilers that
	possibly have the same issue.

	Fix this by moving functions start_sequence and gen_movsd into their own
	files, as a way of trying harder to enforce noinline/noipa/noclone.

	Tested on x86_64-linux.

	[gdb/testsuite] Fix gdb.opt/clobbered-registers-O2.exp with gcc-12
	When running test-case gdb.opt/clobbered-registers-O2.exp with gcc-12, I run

	(gdb) print *operand0^M
	$2 = 4195541^M
	(gdb) FAIL: gdb.opt/clobbered-registers-O2.exp: print operand0
	...

	The problem is that starting gcc-12, the assignments to x and y in main are
	optimized away:
	...
	int main(void)
	{
	  unsigned x, y;

	  x = 13;
	  y = 14;
	  return (int)gen_movsd (&x, &y);
	...

	Fix this by making x and y volatile.

	Note that the test-case intends to check the handling of debug info for
	optimized code in function gen_movsd, so inhibiting optimization in main
	doesn't interfere with that.

	Tested on x86_64-linux.

	$1 = ()^M
	(gdb) FAIL: gdb.ada/dynamic-iface.exp: print local as interface

	More concretely, we have trouble finding the type of obj.  With gcc 8:

	$ gdb -q -batch main -ex "b concrete.adb:20" -ex run -ex "ptype obj"
	  ...
	type = <ref> new concrete.intermediate with record

	The translation from tagged type to "full view" type happens in

	      offset_to_top = value_as_long (value_ind (tem));
	    }
	...
	resulting in an offset_to_top for gcc 8:
	...
	(gdb) p offset_to_top
	$1 = -16
	...
	and for gcc 7:
	...
	(gdb) p offset_to_top
	$1 = 16

	The difference is expected, it bisects to gcc commit d0567dc0dbf ("[multiple

	There's some code right after the code quoted above that deals with this
	change:
	...
	  else if (offset_to_top > 0)
	    {
	      /* OFFSET_TO_TOP used to be a positive value to be subtracted
		 from the base address.  This was however incompatible with
		 C++ dispatch table: C++ uses a *negative* value to *add*
		 to the base address.  Ada's convention has therefore been
		 changed in GNAT 19.0w 20171023: since then, C++ and Ada
		 use the same convention.  Here, we support both cases by
		 checking the sign of OFFSET_TO_TOP.  */
	      offset_to_top = -offset_to_top;
	    }
	...
	but it's not activated because of the 'else'.

	Fix this by removing the 'else'.

	Accept functions with DW_AT_linkage_name present
	Currently GDB is not able to debug (Binary generated with Clang) variables
	present in shared/private clause of OpenMP Task construct. Please note that
	LLVM debugger LLDB is able to debug.

	In case of OpenMP, compilers generate artificial functions which are not
	present in actual program. This is done to apply parallelism to block of
	code.

	For non-artifical functions, DW_AT_name attribute should contains the name
	exactly as present in actual program.
	(Ref# http://wiki.dwarfstd.org/index.php?title=Best_Practices)
	Since artificial functions are not present in actual program they not having
	DW_AT_name and having DW_AT_linkage_name instead should be fine.

	Currently GDB is invalidating any function not havnig DW_AT_name which is why
	it is not able to debug OpenMP (Clang).

	It should be fair to fallback to check DW_AT_linkage_name in case DW_AT_name
	is absent.

	Rename base_breakpoint -> code_breakpoint
	Even after the previous patches reworking the inheritance of several
	breakpoint types, the present breakpoint hierarchy looks a bit
	surprising, as we have "breakpoint" as the superclass, and then
	"base_breakpoint" inherits from "breakpoint".  Like so, simplified:

	   breakpoint
	       base_breakpoint
	          ordinary_breakpoint
		  internal_breakpoint
		  momentary_breakpoint
		  ada_catchpoint
		  exception_catchpoint
	       tracepoint
	       watchpoint
	       catchpoint
		  exec_catchpoint
		  ...

	The surprising part to me is having "base_breakpoint" being a subclass
	of "breakpoint".  I'm just refering to naming here -- I mean, you'd
	expect that it would be the top level baseclass that would be called
	"base".

	Just flipping the names of breakpoint and base_breakpoint around
	wouldn't be super great for us, IMO, given we think of every type of
	*point as a breakpoint at the user visible level.  E.g., "info
	breakpoints" shows watchpoints, tracepoints, etc.  So it makes to call
	the top level class breakpoint.

	Instead, I propose renaming base_breakpoint to code_breakpoint.  The
	previous patches made sure that all code breakpoints inherit from
	base_breakpoint, so it's fitting.  Also, "code breakpoint" contrasts
	nicely with a watchpoint also being typically known as a "data
	breakpoint".

	After this commit, the resulting hierarchy looks like:

	   breakpoint
	       code_breakpoint
	          ordinary_breakpoint
		  internal_breakpoint
		  momentary_breakpoint
		  ada_catchpoint
		  exception_catchpoint
	       tracepoint
	       watchpoint
	       catchpoint
		  exec_catchpoint
		  ...

	... which makes a lot more sense to me.

	I've left this patch as last in the series in case people want to
	bikeshed on the naming.

	"code" has a nice property that it's exactly as many letters as
	"base", so this patch didn't require any reindentation.  :-)

	Make sure momentary breakpoints are always thread-specific
	This adds a new ctor to momentary_breakpoints with a few parameters
	that are always necessary for momentary breakpoints.

	In particular, I noticed that set_std_terminate_breakpoint doesn't
	make the breakpoint be thread specific, which looks like a bug to me.

	The point of that breakpoint is to intercept std::terminate calls that
	happen as result of the called thread throwing an exception that won't
	be caught by the dummy frame.  If some other thread calls
	std::terminate, IMO, it's no different from some other thread calling
	exit/_exit, for example.

	decrementing) the internal breakpoint count.

	Indeed, set_momentary_breakpoint installs the created breakpoint
	without a number.

	However, momentary_breakpoint_from_master incorrectly gives an
	internal breakpoint number to the new breakpoint.  This commit fixes
	that.

	Move add_location(sal) to base_breakpoint
	After the previous patches, only base_breakpoint subclasses use
	add_location(sal), so we can move it to base_breakpoint (a.k.a. base
	class for code breakpoints).

	This requires a few casts here and there, but always at spots where
	you can see from context what the breakpoint's type actually is.

	I inlined new_single_step_breakpoint into its only caller exactly for
	this reason.

	I did try to propagate more use of base_breakpoint to avoid casts, but
	that turned out unwieldy for this patch.

	Make catchpoint inherit breakpoint, eliminate init_raw_breakpoint
	struct catchpoint's ctor currently calls init_raw_breakpoint, which is
	a bit weird, as that ctor-like function takes a sal argument, but
	catchpoints don't have code locations.

	Instead, make struct catchpoint's ctor add the catchpoint's dummy
	location using add_dummy_location.

	init_raw_breakpoint uses add_location under the hood, and with a dummy
	sal it would ultimately use the breakpoint's gdbarch for the
	location's gdbarch, so replace the references to loc->gdbarch (which
	is now NULL) in syscall_catchpoint to references to the catchpoint's
	gdbarch.

	struct catchpoint's ctor was the last user of init_raw_breakpoint, so
	this commit eliminates the latter.

	Since catchpoint locations aren't code locations, make struct
	catchpoint inherit struct breakpoint instead of base_breakpoint.  This
	let's us delete the tracepoint::re_set override too.

	Make breakpoint_address_bits look at the location kind
	Software watchpoints allocate a special dummy location using
	software_watchpoint_add_no_memory_location, and then
	breakpoint_address_bits checks whether the location is that special
	location to decide whether the location has a meaninful address to
	print.

	Introduce a new bp_loc_software_watchpoint location kind, and make
	breakpoint_address_bits use bl_address_is_meaningful instead, which
	returns false for bp_loc_other, which is in accordance with we
	document for bp_location::address:

	  /* (... snip ...)  Valid for all types except
	     bp_loc_other.  */
	  CORE_ADDR address = 0;

	Rename software_watchpoint_add_no_memory_location to
	add_dummy_location, and simplify it.  This will be used by catchpoints
	too in a following patch.

	Note that neither "info breakpoints" nor "maint info breakpoints"
	actually prints the addresses of watchpoints, but I think it would be
	useful to do so in "maint info breakpoints".  This approach let's us
	implement that in the future.

	Finally, init_breakpoint_sal can take a base_breakpoint pointer as

	PowerPC: Make test gdb.arch/powerpc-power10.exp Endian independent.
	The .quad statement stores the 64-bit hex value in Endian order.  When used
	to store a 64-bit prefix instructions on Big Endian (BE) systems, the .quad
	statement stores the 32-bit suffix followed by the 32-bit prefix rather
	than the expected order of prefix word followed by the suffix word.  GDB
	fetches 32-bits at a time when disassembling instructions.  The disassembly
	on BE gets messed up since GDB fetches the suffix first and interprets it
	as a word instruction not a prefixed instruction.  When gdb fetches the
	prefix part of the instruction, following the initial suffix word, gdb
	associates the prefix word incorrectly with the following 32-bits as the
	suffix for the instruction when in fact it is the following instruction.

	For example on BE we have two prefixed instructions stored using the
	.quad statement as follows:

	 addr    word                GDB action
	---------------------------------------------
	  1      suffix inst A   <- GDB interprets as a word instruction
	  2      prefix inst A   <- GDB uses this prefix with

	  3      suffix inst B   <- this suffix rather than the suffix at addr 1.
	  4      prefix inst B

	This patch changes the .quad statement into two .longs to explicitly store
	the prefix followed by the suffix of the instruction.

	The patch rearranges the instructions to put all of the word instructions
	together followed by the prefix instructions for clarity.

	The patch has been tested on Power 10 and Power 7 BE and LE to verify
	the change works as expected.

	add a trie to map quickly from address range to compilation unit
	When using perf to profile large binaries, _bfd_dwarf2_find_nearest_line()
	becomes a hotspot, as perf wants to get line number information
	(for inline-detection purposes) for each and every sample. In Chromium
	in particular (the content_shell binary), this entails going through
	475k address ranges, which takes a long time when done repeatedly.

	Add a radix-256 trie over the address space to quickly map address to
	compilation unit spaces; for content_shell, which is 1.6 GB when some
	(but not full) debug information turned is on, we go from 6 ms to
	0.006 ms (6 µs) for each lookup from address to compilation unit, a 1000x
	speedup.

	There is a modest RAM increase of 180 MB in this binary (the existing
	linked list over ranges uses about 10 MB, and the entire perf job uses
	between 2–3 GB for a medium-size profile); for smaller binaries with few
	ranges, there should be hardly any extra RAM usage at all.

	The problem is that we're passing an empty string_view to
	IS_ABSOLUTE_PATH.  IS_ABSOLUTE_PATH accesses [0] on that string_view,
	which is out-of-bounds.

	The reason this is not seen with -std less than c++17 is that our local
	copy of string_view (used with C++ < 17) does not have the assert in
	operator[], as that wouldn't work in a constexpr method:

	IS_ABSOLUTE_PATH is normally used with null-terminated string.  It's
	fine to pass an empty null-terminated string to IS_ABSOLUTE_PATH,
	because index 0 in such a string is valid.  But not with an empty
	string_view.

	Fix that by avoiding the "call" to IS_ABSOLUTE_PATH if the string_view

	Arm64: force emission of ILP32-dependent relocs
	Like the placeholder types added in 04dfe7aa5217 ("Arm64: follow-on to
	PR gas/27217 fix"), these are also placeholders which are subsequently
	resolved (albeit later, hence this being a separate issue). As for the
	resolved types 1 is returned, these pseudo-relocs should also have 1
	returned to force retaining of the [eventual] relocations. This is also
	spelled out individually for each of them in md_apply_fix().

	COFF: use hash for string table also when copying / stripping
	Otherwise the string table may grow and hence e.g. change a final binary
	(observed with PE/COFF ones) even if really there's no change. Doing so
	in fact reduces the overall amount of code, and in particular the number
	of places which need to remain in sync.

	Afaics there's no real equivalent to the "traditional_format" field used
	when linking, so hashing is always enabled when copying / stripping.

	COFF/PE: keep linker version during objcopy / strip
	Neither of the tools is really a linker, so whatever was originally
	recorded should be retained rather than being overwritten by these
	tools' versions.

	COFF/PE: don't leave zero timestamp after objcopy / strip
	Fill the timestamp field suitably for _bfd_XXi_only_swap_filehdr_out().
	Instead of re-arranging the present if(), fold this logic with that of
	copying the optional header.

	statements with identical code.

	don't over-align file positions of PE executable sections
	When a sufficiently small alignment was specified via --file-alignment,
	individual section alignment shouldn't affect placement within the file.
	This involves first of all clearing D_PAGED for images when section and
	file alignment together don't permit paging of the image. The involved
	comparison against COFF_PAGE_SIZE in turn helped point out (through a
	compiler warning) that 'page_size' should be of unsigned type (as in
	particular FileAlignment is). This yet in turn pointed out a dubious
	error condition (which is being deleted).

	For the D_PAGED case I think the enforced file alignment may still be
	too high, but I'm wary of changing that logic without knowing of
	possible corner cases.

	Furthermore file positions in PE should be independent of the alignment
	recorded in section headers anyway. Otherwise there are e.g. anomalies
	following commit 6f8f6017a0c4 ("PR27567, Linking PE files adds alignment
	section flags to executables") in that linking would use information a
	subsequent processing step (e.g. stripping) wouldn't have available
	anymore, and hence a binary could change in that 2nd step for no actual
	reason. (Similarly stripping a binary linked with a linker pre-dating
	that commit would change the binary again when stripping it a 2nd time.)

	gas: avoid octal numbers being accepted when processing .linefile
	Compilers would put decimal numbers there, so I think we should treat
	finding octal numbers the same as finding bignums - ignore them as
	actually being comments of some very specific form.

2022-05-18  Jan Beulich  <jbeulich@suse.com>

	gas: avoid bignum related errors when processing .linefile
	Any construct which to the scrubber looks like a C preprocessor
	line/file "directive" is converted to .linefile, but the amount of
	checking the scrubber does is minimal (albeit it does let through only
	decimal digits for the line part of the contruct). Since the scrubber
	conversion is further tied to # being a line comment character, anything
	which upon closer inspection turns out not to be a line/file "directive"
	is supposed to be treated as a comment, i.e. ignored. Therefore we
	cannot use get_absolute_expression(), as this may raise errors. Open-
	code the function instead, treating everything not resulting in
	O_constant as a comment as well.

	Furthermore also bounds-check the parsed value. This bounds check tries
	to avoid implementation defined behavior (which may be the raising of an
	implementation defined signal), but for now makes the assumption that
	int has less than 64 bits. The way bfd_signed_vma (which is what offsetT
	aliases) is defined in bfd.h for the BFD64 case I cannot really see a
	clean way of avoiding this assumption. Omitting the #ifdef, otoh, would
	risk "condition is always false" warnings by compilers.

	Convert get_linefile_number() to return bool at this occasion as well.

	gas: fold do_repeat{,_with_expander}()
	do_repeat_with_expander() already deals with the "no expander" case
	quite fine, so there's really little point having two functions. What it
	lacks compared with do_repeat() is a call to sb_build(), which can
	simply be moved (and the then redundant sb_new() be avoided). Along with
	this moving also flip if the main if()'s condition such that the "no
	expander" case is handled first.

	gas: don't ignore .linefile inside false conditionals
	When assembling code previously pre-processed by a C compiler, long
	enough comments may have been collapsed into "# <line> <file>"
	constructs. If we skip these, line numbers (and possibly even file
	names) will be off / wrong in both diagnostics and debug info.

	gas: simplify ignore_input()
	First of all convert to switch(), in preparation of adding another
	directive here which may not be ignored. While doing so drop dead code:
	A string the first two characters of which do not match "if" also wont
	match "ifdef" or "ifndef".

	Make gdb_test's question non-optional if specified
	gdb_test supports handling scenarios where GDB asks a question before
	finishing handling some command.  The full prototype of gdb_test is:

	  # gdb_test COMMAND PATTERN MESSAGE QUESTION RESPONSE

	However, QUESTION is a question that GDB _may_ ask, not one that GDB
	_must_ ask:

	 # QUESTION is a question GDB may ask in response to COMMAND, like
	 #   "are you sure?"
	 # RESPONSE is the response to send if QUESTION appears.

	If GDB doesn't raise the question, the test still passes.

	I think that this is a misfeature.  If GDB regresses and stops asking
	a question, the testsuite won't notice.  So I think that if a QUESTION
	is specified, gdb_test should ensure it comes out of GDB.

	Running the testsuite exposed a number of tests that pass
	QUESTION/RESPONSE to GDB, but no question comes out.  The previous
	commits fixed them all, so this commit changes gdb_test's behavior.

	A related issue is that gdb_test doesn't enforce that if you specify
	QUESTION, that you also specify RESPONSE.  I.e., you should pass 1, 2,
	3, or 5 arguments to gdb_test, but never 4, or more than 5.  Making
	gdb_test detect bogus arguments actually regressed some testcases,
	also all fixed in previous commits.

	gdb.base/skip.exp: Don't abuse gdb_test's question support
	gdb.base/skip.exp abuses gdb_test's support for answering a GDB
	question to do this:

	    # With gcc 9.2.0 we jump once back to main before entering foo here.
	    # If that happens try to step a second time.
	    gdb_test "step" "foo \\(\\) at.*" "step 3" \
		"main \\(\\) at .*\r\n$gdb_prompt " "step"

	After a patch later in this series, gdb_test will FAIL if GDB does NOT
	issue the question, so this test would start failing on older GCCs.

	Switch to using gdb_test_multiple instead.  There are three spots in
	the file that have the same pattern, and they're actually in a
	sequence of commands that is repeated those 3 times.  Factor all that
	out to a procedure.

	I don't have gcc 9.2 handy, but I do have gcc 6.5, and that one is

	does:

	A following patch will make gdb_test expect the question out of GDB if
	one is passed down as argument to gdb_test.  With that, this test
	starts failing.  This is because connect_no_symbol_file is called in a
	loop, and the first time around, there's a loaded file, so "file" asks
	the "Discard symbol table ... ?" question, while in the following
	iterations there's no file, so there's no question.

	gdb.base/scope.exp: Remove bogus gdb_test questions
	This test is abusing the QUESTION/RESPONSE feature to send an
	alternative command to GDB if the first command fails.  Like so:

	   gdb_test "print 'scope0.c'::filelocal" \
		    "\\\$$decimal = 1" "print 'scope0.c'::filelocal at main" \
		    "No symbol \"scope0.c\" in current context.*" \
		    "print '$srcdir/$subdir/scope0.c'::filelocal"

	So if 'scope0.c' doesn't work, we try again with
	'$srcdir/$subdir/scope0.c'.  I strongly suspect this is really an
	obsolete test.  I think that if '$srcdir/$subdir/scope0.c' works, then
	'scope0.c' should have worked too, thus I'd think that if we pass due
	to the question path, then it's a bug.  So just remove the question
	part passed to gdb_test.

	Reindent gdbsupport/event-loop.cc:handle_file_event
	The handle_file_event function has a few unnecessary {} lexical

	conditions were removed, or something along those lines.

	Remove the unnecessary blocks, and reindent.

	gdbsupport/event-loop.cc: simplify !HAVE_POLL paths
	gdbsupport/event-loop.cc throughout handles the case of use_poll being
	true on a system where HAVE_POLL is not defined, by calling
	internal_error if that situation ever happens.

	Simplify this by moving the "use_poll" global itself under HAVE_POLL,
	so that it's way more unlikely to ever end up in such a situation.
	Then, move the code that checks the value of use_poll under HAVE_POLL
	too, and remove the internal_error calls.  Like, from:

	    if (use_poll)
	      {
	  #ifdef HAVE_POLL
	        // poll code
	  #else
	      internal_error (....);
	  #endif /* HAVE_POLL */
	      }
	    else
	      {
		// select code
	      }

	to

	  #ifdef HAVE_POLL
	    if (use_poll)
	      {
	        // poll code
	      }
	    else
	  #endif /* HAVE_POLL */
	      {
		// select code
	      }

	While at it, make use_poll be a bool.  The current code is using
	unsigned char most probably to save space, but I don't think it really
	matters here.

	Fix Ada exception regression on Windows
	The breakpoint c++-ification series introduced another bug in Ada --
	it caused "catch exception" and related commands to fail on Windows.
	The problem is that the re_set method calls the wrong superclass
	method, so the breakpoint doesn't get correctly re-set when the
	runtime offsets change.  This patch fixes the problem.

	gdb/testsuite: fix "continue outside of loop" TCL errors
	Many test cases had a few lines in the beginning that look like:

	if { condition } {
	  continue
	}

	Where conditions varied, but were mostly in the form of ![runto_main] or
	[skip_*_tests], making it quite clear that this code block was supposed
	to finish the test if it entered the code block. This generates TCL
	errors, as most of these tests are not inside loops.  All cases on which
	this was an obvious mistake are changed in this patch.

	Implement pid_to_exec_file for Windows in gdbserver
	I noticed that gdbserver did not implement pid_to_exec_file for
	Windows, while gdb did implement it.  This patch moves the code to
	nat/windows-nat.c, so that it can be shared.  This makes the gdbserver
	implementation trivial.

	Remove windows_process_info::id
	I noticed that windows_process_info::id is only used by gdbserver, and
	not really necessary.  This patch removes it.

	Constify target_pid_to_exec_file
	This changes target_pid_to_exec_file and target_ops::pid_to_exec_file
	to return a "const char *".  I couldn't build many of these targets,
	but did examine the code by hand -- also, as this only affects the
	return type, it's normally pretty safe.  This brings gdb and gdbserver
	a bit closer, and allows for the removal of a const_cast as well.

	Put corefile-run.core into test subdirectory
	I noticed that corefile-run.core ends up in the 'runtest' directory.
	It's better, when at all possible, for test files to end up in the

	This changes coffread.c to avoid re-reading minimal symbols when

	Tested using the AdaCore internal test suite on Windows.  I also did
	some local builds to ensure that no warnings crept in.

	Fix "gdb --write" with core files
	If you load a core file into GDB with the --write option, or "set
	write on" (equivalent), and then poke memory expecting it to patch the
	core binary, you'll notice something odd -- the write seems to
	succeed, but in reality, it doesn't.  The value you wrote doesn't
	persist.  Like so:

	 $ gdb -q --write -c testsuite/outputs/gdb.base/patch/gcore.test
	 [New LWP 615986]
	 Core was generated by `/home/pedro/gdb/build/gdb/testsuite/outputs/gdb.base/patch/patch'.
	 Program terminated with signal SIGTRAP, Trace/breakpoint trap.
	 #0  0x0000555555555131 in ?? ()
	 (gdb) p *(unsigned char *)0x0000555555555131 = 1
	 $1 = 1 '\001'
	 (gdb) p *(unsigned char *)0x0000555555555131
	 $2 = 185 '\271'
	 (gdb)

	Diffing hexdumps of before/after patching, reveals that a "0x1" was
	actually written somewhere in the file.  The problem is that the "0x1"
	was written at the wrong offset in the file...

	That happens because _bfd_elf_set_section_contents does this to seek
	to the section's offset:

	  pos = hdr->sh_offset + offset;
	  if (bfd_seek (abfd, pos, SEEK_SET) != 0
	      || bfd_bwrite (location, count, abfd) != count)
	    return false;

	... and 'hdr->sh_offset' is zero, so we seek to just OFFSET, which is
	incorrect.  The reason 'hdr->sh_offset' is zero is that
	kernel-generated core files normally don't even have a section header
	table (gdb-generated ones do, but that's more an accident than a
	feature), and indeed elf_core_file_p doesn't even try to read sections
	at all:

	  /*  Core files are simply standard ELF formatted files that partition
	      the file using the execution view of the file (program header table)
	      rather than the linking view.  In fact, there is no section header
	      table in a core file.

	      The process status information (including the contents of the general
	      register set) and the floating point register set are stored in a
	      segment of type PT_NOTE.  We handcraft a couple of extra bfd sections
	      that allow standard bfd access to the general registers (.reg) and the
	      floating point registers (.reg2).  */

	  bfd_cleanup
	  elf_core_file_p (bfd *abfd)

	Changing _bfd_elf_set_section_contents from:

	  pos = hdr->sh_offset + offset;

	to:

	  pos = section->filepos + offset;

	fixes it.  If we do that however, the tail end of
	_bfd_elf_set_section_contents ends up as a copy of
	_bfd_generic_set_section_contents, so just call the latter, thus
	eliminating some duplicate code.

	New GDB testcase included, which exercises both patching an executable
	and patching a core file.  Patching an executable already works
	without this fix, because in that case BFD reads in the sections
	table.  Still, we had no testcase for that yet.  In fact, we have no
	"set write on" testcases at all, this is the first one.

	Tested on x86-64 GNU/Linux, gdb, ld, binutils, and gas.

	Make gdb.ada/float-bits.exp more generic
	There are assumptions in the test about the long double format
	being used. While the results are OK for i387 128-bit long doubles, it
	is not correct for IEEE quad 128-bit long doubles.

	Also, depending on the target (64-bit/32-bit), long doubles may not
	be available at all. And it may be the case that the compiler for a 64-bit
	target doesn't support 128-bit long doubles, but GDB might still support it
	internally.

	Lastly, not every long double format has invalid values. Some formats
	consider all values as valid floating point numbers.

	These divergences cause the following FAIL's on aarch64/arm:

	FAIL: gdb.ada/float-bits.exp: print val_long_double
	FAIL: gdb.ada/float-bits.exp: print val_long_double after assignment

	With the above in mind, extend the test a little so it behaves well on
	different architectures and so it works with different long double
	formats.

	Main changes:

	- Use long double values appropriate for the long double format.
	- Test long double assignment to compiler-generated long
	  double variables.
	- Test long double assignment to GDB internal variables.

	Tested on x86_64 (16 PASS), i686 (16 PASS), aarch64 (12 PASS) and arm (9 PASS).

	There are two problems here:
	- the test-case contains a hardcoded "DW_LNS_advance_pc 1" which causes the
	  breakpoint pointing in the middle of an insn
	- the FAIL triggers on aarch64-linux, but not on x86_64-linux, because the
	  test-case uses 'main_label' as the address of the first and only valid entry
	  in the line table, and:
	  - on aarch64-linux, there's no prologue, so main_label and main coincide,
	    while
	  - on x86_64-linux, there's a prologue, so main_label is different from main.

	Fix these problems by:
	- eliminating the use of "DW_LNS_advance_pc 1", and using
	  "DW_LNE_set_address $main_end" instead, and
	- eliminating the use of main_label, using "DW_LNE_set_address $main_start"

	Fix --disable-threading build
	PR build/29110 points out that GDB fails to build on mingw when the
	"win32" thread model is in use.  It turns out that the Fedora cross
	tools using the "posix" thread model, which somehow manages to support
	std::future, whereas the win32 model does not.

	While looking into this, I found that the configuring with
	--disable-threading will also cause a build failure.

	This patch fixes this build by introducing a compatibility wrapper for
	std::future.

	I am not able to test the win32 thread model build, but I'm going to
	ask the reporter to try this patch.

	Fix "b f(std::string)" when current language is C
	If you try to set a breakpoint at a function such as "b
	f(std::string)", and the current language is C, the breakpoint fails
	to be set, like so:

	  (gdb) set language c
	  break f(std::string)
	  Function "f(std::string)" not defined.
	  Make breakpoint pending on future shared library load? (y or [n]) n
	  (gdb)

	The problem is that the code in GDB that expands the std::string
	typedef hits this in c-typeprint.c:

	      /* If we have "typedef struct foo {. . .} bar;" do we want to
		 print it as "struct foo" or as "bar"?  Pick the latter for
		 C++, because C++ folk tend to expect things like "class5
		 *foo" rather than "struct class5 *foo".  We rather
		 arbitrarily choose to make language_minimal work in a C-like
		 way. */
	      if (language == language_c || language == language_minimal)
		{
		  if (type->code () == TYPE_CODE_UNION)
		    gdb_printf (stream, "union ");
		  else if (type->code () == TYPE_CODE_STRUCT)
		    {
		      if (type->is_declared_class ())
			gdb_printf (stream, "class ");
		      else
			gdb_printf (stream, "struct ");
		    }
		  else if (type->code () == TYPE_CODE_ENUM)
		    gdb_printf (stream, "enum ");
		}

	I.e., std::string is expanded to "class std::..." instead of just
	"std::...", and then the "f(class std::..." symbol doesn't exist.

	Fix this by making cp-support.c:inspect_type print the expanded
	typedef type using the language of the symbol whose type we're
	expanding the typedefs for -- in the example in question, the
	"std::string" typedef symbol, which is a C++ symbol.

	Use type_print_raw_options as it seems to me that in this scenario we
	always want raw types, to match the real symbol names.

	Adjust the gdb.cp/break-f-std-string.exp testcase to try setting a
	breakpoint at "f(std::string)" in both C and C++.

	Always pass an explicit language down to c_type_print
	The next patch will want to do language->print_type(type, ...), to
	print a type in a given language, avoiding a dependency on the current
	language.  That doesn't work correctly currently, however, because
	most language implementations of language_defn::print_type call
	c_print_type without passing down the language.  There are two
	overloads of c_print_type, one that takes a language, and one that
	does not.  The one that does not uses the current language, defeating
	the point of calling language->print_type()...

	This commit removes the c_print_type overload that does not take a
	language, and adjusts the codebase throughout to always pass down a
	language.  In most places, there's already an enum language handy.
	language_defn::print_type implementations naturally pass down
	this->la_language.  In a couple spots, like in ada-typeprint.c and
	rust-lang.c there's no enum language handy, but the code is written
	for a specific language, so we just hardcode the language.

	In gnuv3_print_method_ptr, I wasn't sure whether we could hardcode C++
	here, and we don't have an enum language handy, so I made it use the
	current language, just like today.  Can always be improved later.

	Fix "b f(std::string)", always use DMGL_VERBOSE
	Currently, on any remotely modern GNU/Linux system,
	gdb.cp/no-dmgl-verbose.exp fails like so:

	  break 'f(std::string)'
	  Function "f(std::string)" not defined.
	  (gdb) FAIL: gdb.cp/no-dmgl-verbose.exp: gdb_breakpoint: set breakpoint at 'f(std::string)'
	  break 'f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
	  Function "f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)" not defined.
	  (gdb) PASS: gdb.cp/no-dmgl-verbose.exp: DMGL_VERBOSE-demangled f(std::string) is not defined

	This testcase was added back in 2011, here:

	  [patch] Remove DMGL_VERBOSE
	  https://sourceware.org/pipermail/gdb-patches/2011-June/083081.html

	Back then, the testcase would pass cleanly.  It turns out that the
	reason it fails today is that the testcase is exercising something in
	GDB that only makes sense if the program is built for the pre-C++11
	libstc++ ABI.  Back then the C++11 ABI didn't exist yet, but nowadays,
	you need to compile with -D_GLIBCXX_USE_CXX11_ABI=0 to use the old
	ABI.  See "Dual ABI" in the libstdc++ manual, at
	<https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html>.

	If we tweak the gdb.cp/no-dmgl-verbose.exp testcase to force the old
	ABI with -D_GLIBCXX_USE_CXX11_ABI=0, then it passes cleanly.

	So why is it that setting a breakpoint at "f(std::string)" fails with
	modern ABI, but passes with old ABI?

	This is where libiberty demangler's DMGL_VERBOSE option comes in.  The
	Itanium ABI mangling scheme has a shorthand form for std::string (and
	some other types).  See
	<https://itanium-cxx-abi.github.io/cxx-abi/abi.html>:

	  "In addition, the following catalog of abbreviations of the form "Sx" are used:

	     <substitution> ::= St # ::std::
	     <substitution> ::= Sa # ::std::allocator
	     <substitution> ::= Sb # ::std::basic_string
	     <substitution> ::= Ss # ::std::basic_string < char,
							   ::std::char_traits<char>,
							   ::std::allocator<char> >
	     <substitution> ::= Si # ::std::basic_istream<char,  std::char_traits<char> >
	     <substitution> ::= So # ::std::basic_ostream<char,  std::char_traits<char> >
	     <substitution> ::= Sd # ::std::basic_iostream<char, std::char_traits<char> >
	  "

	When the libiberty demangler encounters such a abbreviation, by
	default, it expands it to the user-friendly typedef "std::string",
	"std::iostream", etc..  If OTOH DMGL_VERBOSE is specified, the
	abbreviation is expanded to the underlying, non-typedefed fullname
	"std::basic_string<char, std::char_traits<char>, std::allocator<char> >"
	etc. as documented in the Itanium ABI, and pasted above.  You can see
	the standard abbreviations/substitutions in
	libiberty/cp-demangle.c:standard_subs.

	Back before Jan's patch in 2011, there were parts of GDB that used
	DMGL_VERBOSE, and others that did not, leading to mismatches.  The
	solution back then was to stop using DMGL_VERBOSE throughout.

	GDB has code in place to let users set a breakpoint at a function with
	typedefs in its parameters, like "b f(uint32_t)".  Demangled function
	names as they appear in the symbol tables almost (more on this is in a
	bit) never have typedefs in them, so when processing "b f(uint32_t)"
	GDB first replaces "uint32_t" for its underlying type, and then sets a
	breakpoint on the resulting prototype, in this case "f(unsigned int)".

	Now, if DMGL_VERBOSE is _not_ used, then the demangler demangles the
	mangled name of a function such as "void f(std::string)" that was
	mangled using the standard abbreviations mentioned above really as:

	  "void f(std::string)".

	For example, the mangled name of "void f(std::string)" if you compile
	with old pre-C++11 ABI is "_Z1fSs".  That uses the abbreviation "Ss",
	so if you demangle that without DMGL_VERBOSE, you get:

	  $ echo "_Z1fSs" | c++filt --no-verbose
	  f(std::string)

	while with DMGL_VERBOSE you'd get:

	  $ echo "_Z1fSs" | c++filt
	  f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)

	If, when the user sets a breakpoint at "f(std::string)", GDB would
	replace the std::string typedef for its underlying type using the same
	mechanism I mentioned for the "f(uint32_t)" example above, then GDB
	would really try to set a breakpoint at "f(std::basic_string<char,
	std::char_traits<char>, std::allocator<char> >)", and that would fail,
	as the function symbol GDB knows about for that function, given no
	DMGL_VERBOSE, is "f(std::string)".

	For this reason, the code that expands typedefs in function parameter
	names has an exception for std::string (and other standard
	abbreviation types), such that "std::string" is never
	typedef-expanded.

	And here lies the problem when you try to do "b f(std::string)" with a
	program compiled with the C++11 ABI.  In that case, std::string
	expands to a different underlying type, like so:

	  f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)

	and this symbol naturally mangles differently, as:

	  _Z1fNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE

	and then because this doesn't use the shorthand mangling abbreviation
	for "std::string" anymore, it always demangles as:

	  f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)

	Now, when using the C++11 ABI, and you set a breakpoint at
	"f(std::string)", GDB's typedefs-in-parameters expansion code hits the
	exception for "std::string" and doesn't expand it, so the breakpoint
	fails to be inserted, because the symbol that exists is really the

	  f(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)

	one, not "f(std::string)".

	So to fix things for C++11 ABI, clearly we need to remove the
	"std::string" exception from the typedef-in-parameters expansion
	logic.  If we do just that, then "b f(std::string)" starts working
	with the C++11 ABI.

	However, if we do _just_ that, and nothing else, then we break
	pre-C++11 ABI...

	The solution is then to in addition switch GDB to always use
	DMGL_VERBOSE.  If we do this, then pre-C++11 ABI symbols works the
	same as C++11 ABI symbols overall -- the demangler expands the
	standard abbreviation for "std::string" as "std::basic_string<char,
	std::char_traits<char>, std::allocator<char> >" and letting GDB expand
	the "std::string" typedef (etc.) too is no longer a problem.

	To avoid getting in the situation where some parts of GDB use
	DMGL_VERBOSE and others not, this patch adds wrappers around the
	demangler's entry points that GDB uses, and makes those force
	DMGL_VERBOSE.

	The point of the gdb.cp/no-dmgl-verbose.exp testcase was to try to
	ensure that DMGL_VERBOSE doesn't creep back in:

	 gdb_test {break 'f(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'} \
		  {Function ".*" not defined\.} \
		  "DMGL_VERBOSE-demangled f(std::string) is not defined"

	This obviously no longer makes sense to have, since we now depend on
	DMGL_VERBOSE.  So the patch replaces gdb.cp/no-dmgl-verbose.exp with a
	new gdb.cp/break-f-std-string.exp testcase whose purpose is to make
	sure that setting a breakpoint at "f(std::string)" works.  It
	exercises both pre-C++11 ABI and C++11 ABI.

	gdb/testsuite: fix testsuite regressions for unix/-m32 board
	This commit fixes two regressions introduced by
	891e4190ba705373eec7b374209478215fff5401.

	Reason for the failures was, that on a 32 bit machine the maximum
	array length as well as the maximum allocatable memory for arrays
	(in bytes) both seem to be limited by the maximum value of a 4
	byte (signed) Fortran integer.  This lead to compiler errors/unexpected
	behavior when compiling/running the test with the -m32 board.  This
	behavior is compiler dependent and can differ for different compiler
	implementations, but generally, it seemed like a good idea to simply
	avoid such situations.

	The affected tests check for GDB's overflow behavior when using KIND
	parameters with GDB implemented Fortran intrinsic functions.  If these
	KIND parameters are too small to fit the actual intrinsic function's
	result, an overflow is expected.  This was done for 1, 2, and 4
	byte overflows.  The last one caused problems, as it tried to allocate
	arrays of length/byte-size bigger than the 4 byte signed integers which
	would then be used with the LBOUND/UBOUND/SIZE intrinsics.

	The tests were adapted to only execute the 4 byte overflow tests when
	running on targets with 64 bit.  For this, the compiled tests evaluate the
	byte size of a C_NULL_PTR via C_SIZEOF, both defined in the ISO_C_BINDING
	module.  The ISO_C_BINDING constant C_NULL_PTR is a Fortran 2003, the
	C_SIZEOF a Fortran 2008 extension.  Both have been implemented in their
	respective compilers for while (e.g. C_SIZEOF is available since
	gfortran 4.6).  If this byte size evaluates to less than 8 we skip the
	4 byte overflow tests in the compiled tests of size.f90 and
	lbound-ubound.f90.  Similarly, in the lbound-ubound.exp testsfile we skip
	the 4 byte overflow tests if the procedure is_64_target evaluates to false.

	In size.f90, additionally, the to-be-allocated amount of bytes did not
	fit into 4 byte signed integers for some of the arrays, as it was
	approximately 4 times the maximum size of a 4 byte signed integer.  We
	adapted the dimensions of the arrays in question as the meaningfulness
	of the test does not suffer from this.

	With this patch both test run fine with the unix/-m32 board and
	gcc/gfortran (9.4) as well as the standard board file.

	We also thought about completely removing the affected test from the
	testsuite.  We decided against this as the 32 bit identification comes
	with Fortran 2008 and removing tests would have decreased coverage.

	A last change that happened with this patch was due to gfortran's and
	ifx's type resolution when assigning big constants to Fortran Integer*8
	variables.  Before the above changes this happened in a parameter
	statement.  Here, both compilers happily accepted a line like

	  integer*8, parameter :: var = 2147483647 + 5.

	After this change the assignment is not done as a parameter
	anymore, as this triggered compile time overflow errors.  Instead,
	the assignment is done dynamically, depending on the kind of machine one
	is on.  Sadly, just changing this line to

	  integer*8 :: var
	  var = 2147483647 + 5

	does not work with ifx (or flang for that matter, they behave similarly
	here).  It will create an integer overflow in the addition as ifx deduces
	the type the additon is done in as Integer*4.  So var will actually
	contain the value -2147483644 after this.  The lines

	  integer*8 :: var
	  var = 2147483652

	on the other hand fail to compile with gfortran (9.4.0) as the compiler
	identifies an Integer overflow here.  Finally, to make this work with
	all three compilers an additional parameter has been introduced

	  integer*8, parameter :: helper = 2147483647
	  integer*8 :: var
	  var = helper + 5.

	This works on all 3 compilers as expected.

	enum class visit_state is defined inside the class template

	IBM zSystems: Accept (. - 0x100000000) PCRel32 operands
	as does not accept instructions like brasl %r0,.-0x100000000, because
	of two problems with the generic overflow check:

	1. PCRel32 operands are signed, but are treated as unsigned.

	2. The allowed range for these operands is [-(1 << 32), (1 << 32) - 1],
	   and not [-(1 << 31), (1 << 31) - 1].

	Fix both by disabling the generic overflow check - it's not needed,
	because s390_insert_operand () performs its own.

	gdb/testsuite: fix occasional failure in gdb.mi/mi-multi-commands.exp
	In bug PR gdb/29036, another failure was reported for the test
	gdb.mi/mi-multi-commands.exp.  This test sends two commands to GDB as
	a single write, and then checks that both commands are executed.

	The problem that was encountered here is that the output of the first
	command, which looks like this:

	  ^done,value="\"FIRST COMMAND\""

	Is actually produced in parts, first the '^done' is printed, then the
	',value="\"FIRST COMMAND\"" is printed.

	What was happening is that some characters from the second command
	were being echoed after the '^done' had been printed, but before the
	value part had been printed.  To avoid this issue I've relaxed the
	pattern that checks for the first command a little.  With this fix in
	place the occasional failure in this test is no longer showing up.

	[gdb] Update syscalls/{amd64,i386}-linux.xml
	- Add a script syscalls/gen-header.py, based on syscalls/arm-linux.py.
	- Add a script syscalls/update-linux.sh (alongside update-freebsd.sh and
	  update-netbsd.sh).
	- Use syscalls/update-linux.sh to update syscalls/{amd64,i386}-linux.xml.in.
	- Regenerate syscalls/{amd64,i386}-linux.xml using syscalls/Makefile.

	In gdb/syscalls/i386-linux.xml.in, updating has the following notable effect:
	...
	-  <syscall name="madvise1" number="220"/>
	-  <syscall name="getdents64" number="221"/>
	-  <syscall name="fcntl64" number="222"/>
	+  <syscall name="getdents64" number="220"/>

	gdb: fix for gdb.base/eof-exit.exp test failures
	This fix relates to PR gdb/29032, this makes the test more stable by
	ensuring that the Ctrl-D is only sent once the prompt has been
	displayed.  This issue was also discussed on the mailing list here:

	  https://sourceware.org/pipermail/gdb-patches/2022-April/187670.html

	The problem identified in the bug report is that sometimes the Ctrl-D
	(that the test sends to GDB) arrives while GDB is processing a
	command.  When this happens the Ctrl-D is handled differently than if
	the Ctrl-D is sent while GDB is waiting for input at a prompt.

	The original intent of the test was that the Ctrl-D be sent while GDB
	was waiting at a prompt, and that is the case the occurs most often,
	but, when the Ctrl-D arrives during command processing, then GDB will
	ignore the Ctrl-D, and the test will fail.

	This commit ensures the Ctrl-D is always sent while GDB is waiting at
	a prompt, which makes this test stable.

	But, that still leaves an open question, what should happen when the
	Ctrl-D arrives while GDB is processing a command?  This commit doesn't
	attempt to answer that question, which is while bug PR gdb/29032 will
	not be closed once this commit is merged.

	The current glibc on Tumbleweed is 2.35, which contains commit

	Fix this by detecting whether syscall pipe or pipe2 is used before running the
	tests.

	Tested on x86_64-linux, specifically on:
	- openSUSE Tumbleweed (with glibc 2.35), and
	- openSUSE Leap 15.3 (with glibc 2.31).

	On openSUSE Tumbleweed + target board unix/-m32, this exposes:

	    6 $19 = 18
	    7 (gdb) p 19
	FAIL: gdb.tui/scroll.exp: check cmd window in flip layout
	...

	The "p 19" command is handled by Term::command, which sends the command and then
	does Term::wait_for "^$gdb_prompt [string_to_regexp $cmd]", which:
	- matches the line with "(gdb) p 19", and
	- tries to match the following prompt "(gdb) "

	The problem is that scrolling results in reissuing output before the "(gdb) p
	19", and the second matching triggers on that.  Consequently, wait_for no
	longer translates gdb output into screen actions, and the screen does not
	reflect the result of "p 19".

	Fix this by using a new proc wait_for_region_contents, which in contrast to
	wait_for can handle a multi-line regexp.

	Tested on x86_64-linux with make targets check and check-read1.

	$34 = false^M
	(gdb) FAIL: gdb.cp/casts.exp: print (unsigned long long) &gd == gd_value
	...

	The gd_value is set by this assignment:
	...
	  unsigned long long gd_value = (unsigned long long) &gd;
	...

	The problem here is directly casting from a pointer to a non-pointer-sized
	integer.

	Fix this by adding an intermediate cast to std::uintptr_t.

	with many more UNRESOLVED following.

	The ERROR is a common problem, filed as

	But the many UNRESOLVEDs are due to not checking whether the setup as done in
	the test_setup function succeeds or not.

	Fix this by:
	- making test_setup return an error upon failure
	- handling test_setup error at the call site
	- adding a "setup done" pass/fail to be turned into an unresolved
	  in case of error during setup.

	gdb/readline: fix extra 'quit' message problem
	After these two commits:

	      readline: back-port changes needed to properly detect EOF

	  commit 91395d97d905c31ac38513e4aaedecb3b25e818f
	  Date:   Tue Feb 15 17:28:03 2022 +0000

	      gdb: handle bracketed-paste-mode and EOF correctly

	It was observed that, if a previous command is selected at the
	readline prompt using the up arrow key, then when the command is
	accepted (by pressing return) an unexpected 'quit' message will be
	printed by GDB.  Here's an example session:

	  (gdb) p 123
	  $1 = 123
	  (gdb) p 123
	  quit
	  $2 = 123
	  (gdb)

	In this session the second 'p 123' was entered not by typing 'p 123',
	but by pressing the up arrow key to select the previous command.  It
	is important that the up arrow key is used, typing Ctrl-p will not
	trigger the bug.

	The problem here appears to be readline's EOF detection when handling
	multi-character input sequences.  I have raised this issue on the
	readline mailing list here:

	  https://lists.gnu.org/archive/html/bug-readline/2022-04/msg00012.html

	a solution has been proposed here:

	  https://lists.gnu.org/archive/html/bug-readline/2022-04/msg00016.html

	This patch includes a test for this issue as well as a back-port of
	(the important bits of) readline commit:

	  commit 2ef9cec8c48ab1ae3a16b1874a49bd1f58eaaca1
	  Date:   Wed May 4 11:18:04 2022 -0400

	      fix for setting RL_STATE_EOF in callback mode

	That commit also includes some updates to the readline documentation
	and tests that I have not included in this commit.

	With this commit in place the unexpected 'quit' messages are resolved.

	Introduce catchpoint class
	This introduces a catchpoint class that is used as the base class for
	all catchpoints.  init_catchpoint is rewritten to be a constructor
	instead.

	This changes the hierarchy a little -- some catchpoints now inherit
	from base_breakpoint whereas previously they did not.  This isn't a
	problem, as long as re_set is redefined in catchpoint.

	Add initializers to tracepoint
	This adds some initializers to tracepoint.  I think right now these
	may not be needed, due to obscure rules about zero initialization.
	However, this will change in the next patch, and anyway it is clearer
	to be explicit.

	Remove init_raw_breakpoint_without_location
	This removes init_raw_breakpoint_without_location, replacing it with a
	constructor on 'breakpoint' itself.  The subclasses and callers are
	all updated.

	Disable copying for breakpoint
	It seems to me that breakpoint should use DISABLE_COPY_AND_ASSIGN.
	This patch does this.

	Add constructor to exception_catchpoint
	This adds a constructor to exception_catchpoint and simplifies the
	caller.

	Add constructor to syscall_catchpoint
	This adds a constructor to syscall_catchpoint and simplifies the
	caller.

	Add constructor to signal_catchpoint
	This adds a constructor to signal_catchpoint and simplifies the
	caller.

	Add constructor to solib_catchpoint
	This adds a constructor to solib_catchpoint and simplifies the caller.

	Add constructor to fork_catchpoint
	This adds a constructor to fork_catchpoint and simplifies the caller.

	Remove unnecessary line from catch_exec_command_1
	catch_exec_command_1 clears the new catchpoint's "exec_pathname"
	field, but this is already done by virtue of calling "new".

	Constify breakpoint::print_recreate
	This constifies breakpoint::print_recreate.

	Constify breakpoint::print_mention
	This constifies breakpoint::print_mention.

	Constify breakpoint::print_one
	This constifies breakpoint::print_one.

	Constify breakpoint::print_it
	This constifies breakpoint::print_it.  Doing this pointed out some
	code in ada-lang.c that can be simplified a little as well.

	Move works_in_software_mode to watchpoint
	works_in_software_mode is only useful for watchpoints.  This patch
	moves it from breakpoint to watchpoint, and changes it to return bool.

	Boolify breakpoint::explains_signal
	This changes breakpoint::explains_signal to return bool.

	Remove breakpoint::ops
	The breakpoint::ops field is set but never used.  This removes it.

	Change print_recreate_thread to a method
	This changes print_recreate_thread to be a method on breakpoint.  This
	function is only used as a helper by print_recreate methods, so I
	thought this transformation made sense.

	signal handler function test_signal_handler.  The code at the break point
	looks like:

	     0x<hex address> <test_signal_handler>: endbr64

	On PowerPC with a Linux 5.9 kernel or latter, the address where gdb stops
	after the stepi is in the vdso code inserted by the kernel.  The code at the
	breakpoint looks like:

	  0x<hex address>  <__kernel_start_sigtramp_rt64>:	bctrl

	This is different from other architectures.  As discussed below, recent
	kernel changes involving the vdso for PowerPC have been made changes to the
	signal handler code flow.  PowerPC is now stopping in function
	__kernel_start_sigtramp_rt64.  PowerPC now requires an additional stepi to
	reach the user signal handler unlike other architectures.

	The bp-permanent.exp and kill-after-signal tests run fine on PowerPC with an
	kernel that is older than Linux 5.9.

	The PowerPC 64 signal handler was updated by the Linux kernel 5.9-rc1:

	    commit id: 0138ba5783ae0dcc799ad401a1e8ac8333790df9
	    powerpc/64/signal: Balance return predictor stack in signal trampoline

	An additional change to the PowerPC 64 signal handler was made in Linux
	kernel version 5.11-rc7 :

	     commit id: 24321ac668e452a4942598533d267805f291fdc9
	     powerpc/64/signal: Fix regression in __kernel_sigtramp_rt64() semantics

	The first kernel change, puts code into the user space signal handler (in
	the vdso) as a performance optimization to prevent the call/return stack
	from getting out of balance.  The patch ensures that the entire
	user/kernel/vdso cycle is balanced with the addition of the "brctl"
	instruction.

	The second patch, fixes the semantics of __kernel_sigtramp_rt64().  A new
	symbol is introduced to serve as the jump target from the kernel to the
	trampoline which now consists of two parts.

	The above changes for PowerPC signal handler, causes gdb to stop in the
	kernel code not the user signal handler as expected.  The kernel dispatches
	to the vdso code which in turn calls into the signal handler.  PowerPC is
	special in that the kernel is using a vdso instruction (bctrl) to enter the
	signal handler.

	I do not have access to a system with the first patch but not the second.  I did
	test on Power 9 with the Linux 5.15.0-27-generic kernel.  Both tests fail on
	this Power 9 system.  The two tests also fail on Power 10 with the Linux
	5.14.0-70.9.1.el9_0.ppc64le kernel.

	The following patch fixes the issue by checking if gdb stopped at "signal
	handler called".  If gdb stopped there, the tests verifies gdb is in the kernel
	function __kernel_start_sigtramp_rt64 then does an additional stepi to reach the
	user signal handler.  With the patch below, the tests run without errors on both
	the Power 9 and Power 10 systems with out any failures.

	[gdb/testsuite] Fix gdb.dwarf2/locexpr-data-member-location.exp with nopie
	When running test-case gdb.dwarf2/locexpr-data-member-location.exp with
	target board unix/-fno-PIE/-no-pie/-m32 I run into:
	...
	(gdb) step^M
	26        return 0;^M
	(gdb) FAIL: gdb.dwarf2/locexpr-data-member-location.exp: step into foo
	...

	The problem is that the test-case tries to mimic some gdb_compile_shlib
	behaviour using:
	...
	set flags {additional_flags=-fpic debug}
	get_func_info foo $flags
	...
	but this doesn't work with the target board setting, because we end up doing:
	...
	gcc locexpr-data-member-location-lib.c -fpic -g -lm -fno-PIE -no-pie -m32 \
	  -o func_addr23029.x
	...
	while gdb_compile_shlib properly filters out the -fno-PIE -no-pie.

	Consequently, the address for foo determined by get_func_info doesn't match
	the actual address of foo.

	Fix this by printing the address of foo using the result of gdb_compile_shlib.

	This is because the native-extended-gdbserver automatically connects GDB
	to a GDBserver on startup, and therefore pushes a remote target on the
	initial inferior.  cooked_write_test is currently written in a way that
	errors out if the current inferior has a process_stratum_target pushed.

	Rewrite it to use scoped_mock_context, so it doesn't depend on the
	current inferior (the current one upon entering the function).

	This sequence of functions is invoked due to a series of conditions:

	 1 - The probe-based breakpoint mechanism failed (for some reason) so ...

	 2 - ... gdbserver has to know what type of architecture it is dealing
	     with so it can pick the right breakpoint kind, so it wants to
	     check if we have a 64-bit target.

	 3 - To determine the size of a register, we currently fetch the
	     current thread's register cache, and the current thread pointer
	     is now nullptr.

	In #3, the current thread is nullptr because gdb_read_memory clears it
	on purpose, via set_desired_process, exactly to expose code relying on
	the current thread when it shouldn't.  It was always possible to end
	up in this situation (when the current thread exits), but it was
	harder to reproduce before.

	This commit fixes it by tweaking is_64bit_tdesc to look at the current
	process's tdesc instead of the current thread's tdesc.

	Note that the thread's tdesc is itself filled from the process's
	tdesc, so this should be equivalent:

	 struct regcache *
	 get_thread_regcache (struct thread_info *thread, int fetch)
	 {
	   struct regcache *regcache;

	   regcache = thread_regcache_data (thread);

	 ...
	   if (regcache == NULL)
	     {
	       struct process_info *proc = get_thread_process (thread);

	       gdb_assert (proc->tdesc != NULL);

	       regcache = new_register_cache (proc->tdesc);
	       set_thread_regcache_data (thread, regcache);
	     }
	 ...

	gdb/remote: send qSymbol to all inferiors on startup
	start_remote_1 calls remote_check_symbols after things are set up to
	give the remote side a chance to look up symbols.  One call to
	remote_check_symbols sets the "general thread", if needed, and sends one
	qSymbol packet.  However, a remote target could have more than one
	process on initial connection, and this would send a qSymbol for only
	one of these processes.

	Change it to iterate on all the target's inferiors and send a qSymbol
	packet for each one.

	I tested this by changing gdbserver to spawn two processes on startup:

	gdb/remote: iterate on pspace inferiors in remote_new_objfile
	Commit 152a17495663 ("gdb: prune inferiors at end of
	fetch_inferior_event, fix intermittent failure of
	gdb.threads/fork-plus-threads.exp") broke some tests with the
	native-gdbserver board, such as:

	    (gdb) PASS: gdb.base/step-over-syscall.exp: detach-on-fork=off: follow-fork=child: break cond on target : vfork: break marker
	    continue^M
	    Continuing.^M
	    terminate called after throwing an instance of 'gdb_exception_error'^M

	I can manually reproduce the issue by running (just the commands that
	the test does as a one liner):

	    $ ./gdb -q --data-directory=data-directory \
	          testsuite/outputs/gdb.base/step-over-syscall/step-over-vfork \
		  -ex "tar rem | ../gdbserver/gdbserver - testsuite/outputs/gdb.base/step-over-syscall/step-over-vfork" \
		  -ex "b main" \
		  -ex c \
		  -ex "d 1" \
		  -ex "set displaced-stepping off" \
		  -ex "b *0x7ffff7d7ac5a if main == 0" \
		  -ex "set detach-on-fork off" \
		  -ex "set follow-fork-mode child" \
		  -ex c \
		  -ex "inferior 1" \
		  -ex "b marker" \
		  -ex c

	... where 0x7ffff7d7ac5a is the exact address of the vfork syscall
	(which can be found by looking at gdb.log).

	The important part of the above is that a vfork syscall creates inferior
	2, then inferior 2 executes until exit, then we switch back to inferior
	1 and try to resume it.

	The uncaught exception happens here:

	    #4  0x00005596969d81a9 in error (fmt=0x559692da9e40 "Cannot execute this command while the target is running.\nUse the \"interrupt\" command to stop the target\nand then try again.")

	      [infrun] maybe_call_commit_resumed_all_targets: calling commit_resumed for target remote
	    terminate called after throwing an instance of 'gdb_exception_error'

	What happens is:

	 - After doing the "continue" on inferior 1, the remote target gives us
	   a VFORK_DONE event.  The core ignores it and resumes inferior 1.
	 - Since prune_inferiors is now called after each handled event, in
	   fetch_inferior_event, it is called after we handled that VFORK_DONE
	   event and resumed inferior 1.
	 - Inferior 2 is pruned, which (see backtrace above) causes its program
	   space to be deleted, which clears the symtabs for that program space,
	   which calls the new_objfile observable and remote_new_objfile
	   observer (with a nullptr objfile, to indicate that the previously
	   loaded symbols have been discarded), which calls
	   remote_check_symbols.

	remote_check_symbols is the function that sends the qSymbol packet, to
	let the remote side ask for symbol addresses.  The problem is that the
	remote target is working in all-stop / sync mode and is currently
	resumed.  It has sent a vCont packet to resume the target and is waiting
	for a stop reply.  It can't send any packets in the mean time.  That
	causes the exception to be thrown.

	This wasn't a problem before, when prune_inferiors was called in
	normal_stop, because it was always called at a time the target was not
	resumed.

	An important observation here is that the new_objfile observable is
	invoked for a change in inferior 2's program space (inferior 2's program
	space is the current program space).  Inferior 2 isn't bound to any
	process on the remote side (it has exited, that's why it's being
	pruned).  It doesn't make sense to try to send a qSymbol packet for a
	process that doesn't exist on the remote side.  remote_check_symbols
	actually attempts to avoid that:

	   /* The remote side has no concept of inferiors that aren't running
	     yet, it only knows about running processes.  If we're connected
	     but our current inferior is not running, we should not invite the
	     remote target to request symbol lookups related to its
	     (unrelated) current process.  */
	  if (!target_has_execution ())
	    return;

	The problem here is that while inferior 2's program space is the current
	program space, inferior 1 is the current inferior.  So the check above
	passes, since inferior has execution.  We therefore try to send a
	qSymbol packet for inferior 1 in reaction to a change in inferior 2's
	program space, that's wrong.

	This exposes a conceptual flaw in remote_new_objfile.  The "new_objfile"
	event concerns a specific program space, which can concern multiple
	inferiors, as inferiors can share a program space.  We shouldn't
	consider the current inferior at all, but instead all inferiors bound to
	the affected program space.  Especially since the current inferior can
	be unrelated to the current program space at that point.

	To be clear, we are in this state because ~program_space sets itself as
	the current program space, but there is no more inferior having that
	program space to switch to, inferior 2 has already been unlinked.

	To fix this, make remote_new_objfile iterate on all inferiors bound to
	the affected program space.  Remove the target_has_execution check from
	remote_check_symbols, replace it with an assert.  All callers must
	ensure that the current inferior has execution before calling it.

	gdbserver: track current process as well as current thread
	The recent commit 421490af33bf ("gdbserver/linux: Access memory even
	if threads are running") caused a regression in
	gdb.threads/access-mem-running-thread-exit.exp with gdbserver, which I
	somehow missed.  Like so:

	 (gdb) print global_var
	 Cannot access memory at address 0x555555558010
	 (gdb) FAIL: gdb.threads/access-mem-running-thread-exit.exp: non-stop: access mem (print global_var after writing, inf=2, iter=1)

	The problem starts with GDB telling GDBserver to select a thread, via
	the Hg packet, which GDBserver complies with, then that thread exits,
	and GDB, without knowing the thread is gone, tries to write to memory,
	through the context of the previously selected Hg thread.

	GDBserver's GDB-facing memory access routines, gdb_read_memory and
	gdb_write_memory, call set_desired_thread to make GDBserver re-select
	the thread that GDB has selected with the Hg packet.  Since the thread
	is gone, set_desired_thread returns false, and the memory access
	fails.

	Now, to access memory, it doesn't really matter which thread is
	selected.  All we should need is the target process.  Even if the
	thread that GDB previously selected is gone, and GDB does not yet know
	about that exit, it shouldn't matter, GDBserver should still know
	which process that thread belonged to.

	Fix this by making GDBserver track the current process separately,
	like GDB also does.  Add a new set_desired_process routine that is
	similar to set_desired_thread, but just sets the current process,
	leaving the current thread as NULL.  Use it in the GDB-facing memory
	read and write routines, to avoid failing if the selected thread is
	gone, but the process is still around.

	Fix gdb.threads/access-mem-running-thread-exit.exp w/ native-extended-gdbserver
	When testing gdb.threads/access-mem-running-thread-exit.exp with
	--target_board=native-extended-gdbserver, we get:

	  Running gdb.threads/access-mem-running-thread-exit.exp ...
	  FAIL: gdb.threads/access-mem-running-thread-exit.exp: non-stop: second inferior: runto: run to main
	  WARNING: Timed out waiting for EOF in server after monitor exit

			  === gdb Summary ===

	  # of expected passes            3
	  # of unexpected failures        1
	  # of unsupported tests          1

	The problem is that the testcase spawns a second inferior with
	-no-connection, and then runto_main does "run", which fails like so:

	 (gdb) run
	 Don't know how to run.  Try "help target".
	 (gdb) FAIL: gdb.threads/access-mem-running-thread-exit.exp: non-stop: second inferior: runto: run to main

	That "run" above failed because native-extended-gdbserver forces "set
	auto-connect-native-target off", to prevent testcases from mistakenly
	running programs with the native target, which would exactly be the
	case here.

	Fix this by letting the second inferior share the first inferior's
	connection everywhere except on targets that do reload on run (e.g.,
	--target_board=native-gdbserver).

	gdb: add some additional thread status debug output
	While working on this patch:

	  https://sourceware.org/pipermail/gdb-patches/2022-January/185109.html

	I found it really useful to print the executing/resumed status of all
	threads (or all threads in a particular inferior) at various
	places (e.g. when a new inferior is started, when GDB attaches, etc).

	This debug was originally part of the above patch, but I wanted to
	rewrite this as a separate patch and move the code into a new function
	in infrun.h, which is what this patch does.

	Unless 'set debug infrun on' is in effect, then there should be no

	gdb/testsuite: small cleanup in mi-break-qualified.exp
	It is not necessary to pass an empty string to mi_gdb_start, passing
	the empty string is equivalent to passing no arguments, which is what
	we do everywhere else (that we don't need to specify an actual
	argument).

	The only place we use 'mi_gdb_start ""' is in
	gdb.mi/mi-break-qualified.exp, so in this commit I just replace that
	with a call to 'mi_gdb_start' - just for consistency.

	There should be no change in what is tested after this commit.

2022-05-03  Andrew Burgess  <aburgess@redhat.com>

	gdb/testsuite: change mi_gdb_start to take a list of flags
	After this previous commit I was thinking about the API of
	mi_gdb_start.  I felt that the idea of passing flags as separate
	arguments and using 'args' to gather these into a list, though clever,
	was not an intuitive API.

	In this commit I modify mi_gdb_start so that it expects a single
	argument, which should be a list of flags.  Thus, where we previously
	would have said:

	  mi_gdb_start separate-mi-tty separate-inferior-tty

	We would now say:

	  mi_gdb_start { separate-mi-tty separate-inferior-tty }

	However, it turns out we never actually call mi_gdb_start passing two
	arguments in this way at all.  We do in some places do this:

	  mi_gdb_start separate-inferior-tty

	But that's fine, a single string like this works equally well as a
	single item list, so this will not need updating.

	There is also one place where we do this:

	  eval mi_gdb_start $start_ops

	where $start_ops is a list that might contains 0, 1, or 2 items.  The
	eval here is used to expand the $start_ops list so mi_gdb_start sees
	the list contents as separate arguments.  In this case we just need to
	drop the use of eval.

	I think that the new API is more intuitive, but others might
	disagree, in which case I can drop this change.

	There should be no change in what is tested after this commit.

2022-05-03  Andrew Burgess  <aburgess@redhat.com>

	gdb/testsuite: fix mi-exec-run.exp with native-extended-gdbserver board
	When running with the native-extended-gdbserver board, I currently see
	one failure in gdb.mi/mi-exec-run.exp:

	    FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: force-fail=0: breakpoint hit reported on console (timeout)

	In this test the MI interface should be started in a separate tty,
	which means we should have a CLI tty and an MI tty, however, this is
	not happening.  Instead GDB is just started in MI mode and there is no
	CLI tty.

	The test script tries to switch between the CLI an MI terminals and
	look for some expected output on each, however, as there is no CLI
	terminal the expected output never arrives, and the test times out.

	It turns out that this is not a GDB problem, rather, this is an issue
	with argument passing within the test script.

	The proc default_mi_gdb_start expects to take a set of flags (strings)
	as arguments, each of flag is expected to be a separate argument.  The
	default_mi_gdb_start proc collects all its arguments into a list using
	the special 'args' parameter name, and then iterates over this list to
	see which flags were passed.

	In mi_gdb_start, which forwards to default_mi_gdb_start, the arguments
	are also gathered into the 'args' parameter list, but are then
	expanded back to be separate arguments using the eval trick, i.e.:

	  proc mi_gdb_start { args } {
	    return [eval default_mi_gdb_start $args]
	  }

	This ensures that when we arrive in default_mi_gdb_start each flag is
	a separate argument, rather than appearing as a single list containing
	all arguments.

	When using the native-extended-gdbserver board however, the file
	boards/native-extended-gdbserver.exp is loaded, and this file replaces
	the default mi_gdb_start with its own version.

	This new mi_gdb_start also gathers the arguments into an 'args' list,
	but forgets to expand the arguments out using the eval trick.

	As a result, when using the native-extended-gdbserver board, by the
	time we get to default_mi_gdb_start, we end up with the args list
	containing a single item, which is a list containing all the arguments
	the user passed.

	What this means is that if the user passes two arguments, then, in
	default_mi_gdb_start, instead of seeing two separate arguments, we see
	a single argument made by concatenating the two arguments together.

	The only place this is a problem is in the test mi-exec-run.exp,
	which (as far as I can see) is the only test where we might try to
	pass both arguments at the same time.  Currently we think we passed
	both arguments to mi_gdb_start, but mi_gdb_start behaves as if no
	arguments were passed.

	gdb: fix failures in gdb.mi/mi-exec-run.exp with native-extended-gdbserver
	When running the gdb.mi/mi-exec-run.exp test using the
	native-extended-gdbserver I see failures like this:

	  FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=main: mi=main: force-fail=1: run failure detected
	  FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=main: mi=separate: force-fail=1: run failure detected
	  FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: force-fail=1: run failure detected

	There's a race condition here, so you might see a slightly different
	set of failures, but I always see some from the 'run failure detected'
	test.

	NOTE: I also see an additional test failure:

	 FAIL: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: force-fail=0: breakpoint hit reported on console (timeout)

	but that is a completely different issue, and is not being addressed
	in this commit.

	The problem for the 'run failure detected' test is that we end up
	in gdb_expect looking for output from two spawn-ids, one from
	gdbserver, and one from gdb.  We're looking for one output pattern
	from each spawn-id, and for the test to pass we need to see both
	patterns.

	Now, if gdb exits then this is a test failure (this would indicate gdb
	crashing, which is bad), so we have an eof pattern associated with
	the gdb spawn-id.

	However, in this particular test we expect gdbserver to fail to
	execute the binary (the test binary is set non-executable), and so we
	get an error message from gdbserver (which matches the pattern), and
	then gdbserver exits, this is expected.

	The problem is that after spotting the pattern from gdbserver, we
	often see the eof from gdbserver before we see the pattern from gdb.
	If this happens then we drop out of the gdb_expect without ever seeing
	the pattern from gdb, and fail the test.

	In this commit, I place the spawn-id of gdbserver into a global
	variable, and then use this global variable as the -i option within
	the gdb_expect.

	Now, once we have seen the expected pattern on the gdbserver spawn-id,
	the global variable is cleared.  After this the gdb_expect no longer
	checks the gdbserver spawn-id for additional output, and so never sees
	the eof event.  This leaves the gdb_expect running, which allows the
	pattern from gdb to be seen, and for the test to pass.

	I now see no failures relating to 'run failure detected'.

	Fix Ada catchpoint regression
	The breakpoint C++-ification series introduced a regression for Ada
	catchpoints.  Specifically, commit 2b5ab5b8 ("Convert base breakpoints

	because testing Ada using a Linux distro compiler requires installing
	the GNAT debuginfo, which I hadn't done.

	Remove create_breakpoints_sal_default
	create_breakpoints_sal_default is just a simple wrapper, so remove it.

	Remove allocate_bp_location
	allocate_bp_location is just a small wrapper for a method call, so
	inline it everywhere.

	Constify breakpoint_ops
	Now that all breakpoint_ops are statically initialized, they can all
	be made const.

	Remove breakpoint ops initialization
	initialize_breakpoint_ops does not do much any more, so remove it in
	favor of statically-initialize objects.

	Remove vtable_breakpoint_ops
	There's no need to have vtable_breakpoint_ops any more, so remove it
	in favor of base_breakpoint_ops.

	Remove most fields from breakpoint_ops
	At this point, all implementations of breakpoints use the vtable.  So,
	we can now remove most function pointers from breakpoint_ops and
	switch to using methods directly in the callers.  Only the two "static
	virtual" methods remain in breakpoint_ops.

	Remove breakpoint_ops from init_catchpoint
	init_catchpoint is only ever passed a single breakpoint_ops pointer,
	so remove the parameter.

	Remove breakpoint_ops from init_ada_exception_breakpoint
	init_ada_exception_breakpoint is only ever passed a single
	breakpoint_ops structure, so remove the parameter.

	Right now, probe tracepoints are handled by a separate ops object.

	Right now, probe breakpoints are handled by a separate ops object.
	However, they differ only in a small way from ordinary breakpoints,
	and furthermore can be distinguished by their "probe" object.

	This patch merges the two cases.  This avoids having to introduce a
	new bp_ constant (which can be quite subtle to do correctly) and a new
	subclass.

2022-04-29  Tom Tromey  <tom@tromey.com>

	Remove bkpt_base_breakpoint_ops
	An earlier patch removed the last use of bkpt_base_breakpoint_ops, so
	remove the object entirely.

	Convert static marker tracepoints to vtable ops
	This converts static marker tracepoints to use vtable_breakpoint_ops.

	Add bp_static_marker_tracepoint
	Because the actual construction of a breakpoint is buried deep in
	create_breakpoint, at present it's necessary to have a new bp_
	enumerator constant any time a new subclass is needed.  Static marker
	tracepoints are one such case, so this patch introduces
	bp_static_marker_tracepoint and updates various spots to recognize it.

	Convert ranged breakpoints to vtable ops
	This converts ranged breakpoints to use vtable_breakpoint_ops.  This
	requires introducing a new ranged_breakpoint type, but this is
	relatively simple because ranged breakpoints can only be created by
	break_range_command.

	Convert dprintf to vtable ops
	This converts dprintf to use vtable_breakpoint_ops.

	Convert Ada catchpoints to vtable ops
	This converts Ada catchpoints to use vtable_breakpoint_ops.

	Convert ordinary breakpoints to vtable ops
	This converts "ordinary" breakpoint to use vtable_breakpoint_ops.
	Recall that an ordinary breakpoint is both the kind normally created
	by users, and also a base class used by other classes.

	Change inheritance of dprintf
	The dprintf breakpoint ops is mostly a copy of bpkt_breakpoint_ops,
	except it's written out explicitly -- and, importantly, there's
	nothing that bpkt_breakpoint_ops overrides that dprintf does not.
	This changes dprintf to simply inherit directly, and updates struct
	dprintf_breakpoint to reflect the change as well.

	Convert momentary breakpoints to vtable ops
	This converts momentary breakpoints to use vtable_breakpoint_ops.

	Convert internal breakpoints to vtable ops
	This converts internal breakpoints to use vtable_breakpoint_ops.

	Convert break-catch-throw to vtable ops
	This converts break-catch-throw.c to use vtable_breakpoint_ops.

	Convert base breakpoints to vtable ops
	This converts base breakpoints to use vtable_breakpoint_ops.

2022-04-29  Tom Tromey  <tom@tromey.com>

	Add some new subclasses of breakpoint
	This adds a few new subclasses of breakpoint.  The inheritance
	hierarchy is chosen to reflect what's already present in
	initialize_breakpoint_ops -- it mirrors the way that the _ops
	structures are filled in.

	This patch also changes new_breakpoint_from_type to create the correct
	sublcass based on bptype.  This is important due to the somewhat
	inverted way in which create_breakpoint works; and in particular later
	patches will change some of these entries.

2022-04-29  Tom Tromey  <tom@tromey.com>

	Convert tracepoints to vtable ops
	This converts tracepoints to use vtable_breakpoint_ops.

	Convert watchpoints to vtable ops
	This converts watchpoints and masked watchpoints. to use
	vtable_breakpoint_ops.  For masked watchpoints, a new subclass must be
	introduced, and watch_command_1 is changed to create one.

	Convert break-catch-load to vtable ops
	This converts break-catch-load.c to use vtable_breakpoint_ops.

	Convert break-catch-fork to vtable ops
	This converts break-catch-fork.c to use vtable_breakpoint_ops.

	Convert break-catch-exec to vtable ops
	This converts break-catch-exec.c to use vtable_breakpoint_ops.

	Convert break-catch-syscall to vtable ops
	This converts break-catch-syscall.c to use vtable_breakpoint_ops.

	Convert break-catch-sig to use vtable ops
	This converts break-catch-sig.c to use vtable_breakpoint_ops.

2022-04-29  Tom Tromey  <tom@tromey.com>

	Add a vtable-based breakpoint ops
	This adds methods to struct breakpoint.  Each method has a similar
	signature to a corresponding function in breakpoint_ops, with the
	exceptions of create_sals_from_location and create_breakpoints_sal,
	which can't be virtual methods on breakpoint -- they are only used
	during the construction of breakpoints.

	Then, this adds a new vtable_breakpoint_ops structure and populates it
	with functions that simply forward a call from breakpoint_ops to the
	corresponding virtual method.  These are all done with lambdas,
	because they are just a stepping stone -- by the end of the series,
	this structure will be deleted.

2022-04-29  Tom Tromey  <tom@tromey.com>

	Return bool from breakpoint_ops::print_one
	This changes breakpoint_ops::print_one to return bool, and updates all
	the implementations and the caller.  The caller is changed so that a
	NULL check is no longer needed -- something that will be impossible
	with a real method.

	Delete some unnecessary wrapper functions
	This patch deletes a few unnecessary wrapper functions from
	breakpoint.c.

	Add an assertion to clone_momentary_breakpoint
	This adds an assertion to clone_momentary_breakpoint.  This will
	eventually be removed, but in the meantime is is useful for helping
	convince oneself that momentary breakpoints will always use
	momentary_breakpoint_ops.  This understanding will help when cleaning
	up the code later.

	Boolify print_solib_event
	Change print_solib_event to accept a bool parameter and update the
	callers.

	Move "catch load" to a new file
	The "catch load" code is reasonably self-contained, and so this patch
	moves it out of breakpoint.c and into a new file, break-catch-load.c.
	One function from breakpoint.c, print_solib_event, now has to be
	exposed, but this seems pretty reasonable.

	De-duplicate .gdb_index
	This de-duplicates variables and types in .gdb_index, making the new
	index closer to what gdb generated before the new DWARF scanner
	series.  Spot-checking the resulting index for gdb itself, it seems
	that the new scanner picks up some extra symbols not detected by the
	old one.  I tested both the new and old versions of gdb on both new
	and old versions of the index, and startup time in all cases is
	roughly the same (it's worth noting that, for gdb itself, the index no
	longer provides any benefit over the DWARF scanner).  So, I think this
	fixes the size issue with the new index writer.

2022-04-29  Tom Tromey  <tromey@adacore.com>

	Fix .debug_names regression with new indexer
	At AdaCore, we run the internal gdb test suite in several modes,
	including one using the .debug_names index.  This caught a regression
	caused by the new DWARF indexer.

	First, the psymtabs-based .debug_names generator was completely wrong.
	However, to avoid making the rewrite series even bigger (fixing the
	writer will also require rewriting the .debug_names reader), it
	attempted to preserve the weirdness.

	However, this was not done properly.  For example the old writer did
	this:

	-      case STRUCT_DOMAIN:
	-	return DW_TAG_structure_type;

	The new code, instead, simply preserves the actual DWARF tag -- but
	this makes future lookups fail, because the .debug_names reader only
	looks for DW_TAG_structure_type.

	This patch attempts to revert to the old behavior in the writer.

	After handling the EXITED event for inferior 2, inferior 2 should have
	stayed the current inferior, which should have prevented it from getting
	pruned.  When debugging, we find that when getting at the
	prune_inferiors call, the current inferior is inferior 1.  Further
	debugging shows that prior to the call to
	clean_up_just_stopped_threads_fsms, the current inferior is inferior 2,
	and after, it's inferior 1.  Then, back in fetch_inferior_event, the
	restore_thread object is disabled, due to:

		    /* If we got a TARGET_WAITKIND_NO_RESUMED event, then the
		       previously selected thread is gone.  We have two
		       choices - switch to no thread selected, or restore the
		       previously selected thread (now exited).  We chose the
		       later, just because that's what GDB used to do.  After
		       this, "info threads" says "The current thread <Thread
		       ID 2> has terminated." instead of "No thread
		       selected.".  */
		    if (!non_stop
			&& cmd_done
			&& ecs->ws.kind () != TARGET_WAITKIND_NO_RESUMED)
		      restore_thread.dont_restore ();

	So in the end, inferior 1 stays current, and inferior 2 gets wrongfully
	pruned.

	I'd say clean_up_just_stopped_threads_fsms is the culprit here.  It
	actually attempts to restore the event_thread to be current at the end,
	after the loop (I presume the current thread on entry is always supposed
	to be the event thread).  But in this case, the event is of kind EXITED,
	and ecs->event_thread is not set, so the current inferior isn't
	restored.

	Fix that by using scoped_restore_current_thread.  If there is no current
	thread, scoped_restore_current_thread will still restore the current
	inferior, and that's what we want.

	Random note: the thread_info object for inferior 2's thread is never
	freed.  It is held (by refcount) by the restore_thread object in
	fetch_inferior_event, while the inferior's thread list gets cleared, in
	the exit event processing.  When the refcount reaches 0 (when the
	restore_thread object is destroyed), there's nothing that actually
	deletes the thread_info object.  And I think that nothing in GDB points
	to it anymore, so it leaks.  I don't want to fix that in this patch, but
	thought it would be good to mention it, in case somebody has an idea for
	how to fix that.

	Slightly tweak and clarify target_resume's interface
	The current target_resume interface is a bit odd & non-intuitive.
	I've found myself explaining it a couple times the recent past, while
	reviewing patches that assumed STEP/SIGNAL always applied to the
	passed in PTID.  It goes like this today:

	  - if the passed in PTID is a thread, then the step/signal request is
	    for that thread.

	  - otherwise, if PTID is a wildcard (all threads or all threads of
	    process), the step/signal request is for inferior_ptid, and PTID
	    indicates which set of threads run free.

	Because GDB always switches the current thread to "leader" thread
	being resumed/stepped/signalled, we can simplify this a bit to:

	  - step/signal are always for inferior_ptid.

	  - PTID indicates the set of threads that run free.

	Still not ideal, but it's a minimal change and at least there are no
	special cases this way.

	That's what this patch does.  It renames the PTID parameter to
	SCOPE_PTID, adds some assertions to target_resume, and tweaks
	target_resume's description.  In addition, it also renames PTID to
	SCOPE_PTID in the remote and linux-nat targets, and simplifies their
	implementation a little bit.  Other targets could do the same, but
	they don't have to.

	gdb: fix nullptr dereference in block::ranges()
	This commit:

	  commit f5cb8afdd297dd68273d98a10fbfd350dff918d8
	  Date:   Sun Feb 6 22:27:53 2022 -0500

	      gdb: remove BLOCK_RANGES macro

	introduces a potential nullptr dereference in block::ranges, this is
	breaking most tests, e.g. gdb.base/break.exp is failing for me.

	In the above patch BLOCK_CONTIGUOUS_P is changed from this:

	  #define BLOCK_CONTIGUOUS_P(bl)  (BLOCK_RANGES (bl) == nullptr \
	                                   || BLOCK_NRANGES (bl) <= 1)

	to this:

	  #define BLOCK_CONTIGUOUS_P(bl)  ((bl)->ranges ().size () == 0 \
	                                   || (bl)->ranges ().size () == 1)

	So, before the commit we checked for the block ranges being nullptr,
	but afterwards we just call block::ranges() in all cases.

	The problem is that block::ranges() looks like this:

	  /* Return a view on this block's ranges.  */
	  gdb::array_view<blockrange> ranges ()
	  { return gdb::make_array_view (m_ranges->range, m_ranges->nranges); }

	where m_ranges is:

	  struct blockranges *m_ranges;

	And so, we see that the nullptr check has been lost, and we might end
	up dereferencing a nullptr.

	My proposed fix is to move the nullptr check into block::ranges, and
	return an explicit empty array_view if m_ranges is nullptr.

	After this, everything seems fine again.

	libctf: impose an ordering on conflicting types
	When two types conflict and they are not types which can have forwards
	(say, two arrays of different sizes with the same name in two different
	TUs) the CTF deduplicator uses a popularity contest to decide what to
	do: the type cited by the most other types ends up put into the shared
	dict, while the others are relegated to per-CU child dicts.

	This works well as long as one type *is* most popular -- but what if
	there is a tie?  If several types have the same popularity count,
	we end up picking the first we run across and promoting it, and
	unfortunately since we are working over a dynhash in essentially
	arbitrary order, this means we promote a random one.  So multiple
	runs of ld with the same inputs can produce different outputs!
	All the outputs are valid, but this is still undesirable.

	Adjust things to use the same strategy used to sort types on the output:
	when there is a tie, always put the type that appears in a CU that
	appeared earlier on the link line (and if there is somehow still a tie,
	which should be impossible, pick the type with the lowest type ID).

	Add a testcase -- and since this emerged when trying out extern arrays,
	check that those work as well (this requires a newer GCC, but since all
	GCCs that can emit CTF at all are unreleased this is probably OK as
	well).

	Fix up one testcase that has slight type ordering changes as a result
	of this change.

	Make gdb.base/parse_number.exp test all architectures
	There are some subtle differences between architectures, like the size
	of a "long" type, and this isn't currently accounted for in
	gdb.base/parse_number.exp.

	For example, on aarch64 a long type is 8 bytes, whereas a long type is
	4 bytes for x86_64.  This causes the following FAIL's:

	 FAIL: gdb.base/parse_number.exp: lang=asm: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=auto: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=c: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=c++: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=fortran: p/x 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=fortran: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=go: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=local: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=minimal: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=objective-c: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=opencl: ptype 0xffffffffffffffff
	 FAIL: gdb.base/parse_number.exp: lang=pascal: ptype 0xffffffffffffffff

	There are some fortran-specific divergences as well, where 32-bit
	architectures show "unsigned int" for both 32-bit and 64-bit integers
	and 64-bit architectures show "unsigned int" and "unsigned long" for
	32-bit and 64-bit integers.

	There might be a bug that 32-bit fortran truncates 64-bit values to
	32-bit, given "p/x 0xffffffffffffffff" returns "0xffffffff".

	Here's what we get for aarch64:

	 (gdb) ptype 0xffffffff
	 type = unsigned int
	 (gdb) ptype 0xffffffffffffffff
	 type = unsigned long
	 (gdb) p sizeof (0xffffffff)
	 $1 = 4
	 (gdb) p sizeof (0xffffffffffffffff)
	 quit
	 $2 = 8
	 (gdb) ptype 0xffffffff
	 type = unsigned int
	 (gdb) ptype 0xffffffffffffffff
	 type = unsigned long

	And for arm:

	 (gdb) ptype 0xffffffff
	 type = unsigned int
	 (gdb) ptype 0xffffffffffffffff
	 quit
	 type = unsigned long long
	 (gdb) p sizeof (0xffffffff)
	 quit
	 $1 = 4
	 (gdb) p sizeof (0xffffffffffffffff)
	 quit
	 $2 = 8
	 (gdb) ptype 0xffffffff
	 type = unsigned int
	 (gdb) ptype 0xffffffffffffffff
	 type = unsigned long

	This patch...

	* Makes the testcase iterate over all architectures, thus covering all
	  the different combinations of types/sizes every time.

	* Adjusts the expected values and types based on the sizes of long
	  long, long and int.

	A particularly curious architecture is s12z, which has 32-bit long
	long, and thus no way to represent 64-bit integers in C-like
	languages.

	gdb/arm: Extend arm_m_addr_is_magic to support FNC_RETURN, add unwind-secure-frames command
	This patch makes use of the support for several stack pointers
	introduced by the previous patch to switch between them as needed
	during unwinding.

	It introduces a new 'unwind-secure-frames' arm command to enable/disable
	mode switching during unwinding. It is enabled by default.

	It has been tested using an STM32L5 board (with cortex-m33) and the
	sample applications shipped with the STM32Cube development
	environment: GTZC_TZSC_MPCBB_TrustZone in
	STM32CubeL5/Projects/NUCLEO-L552ZE-Q/Examples/GTZC.

	The test consisted in setting breakpoints in various places and check
	that the backtrace is correct: SecureFault_Callback (Non-secure mode),
	__gnu_cmse_nonsecure_call (before and after the vpush instruction),
	SecureFault_Handler (Secure mode).

	This implies that we tested only some parts of this patch (only MSP*
	were used), but remaining parts seem reasonable.

	GDB PowerPC record test cases for ISA 2.06 and ISA 3.1
	This patch adds PowerPC specific tests to verify recording of various
	instructions.  The first test case checks the ISA 2.06 lxvd2x instruction.
	The second test case tests several of the ISA 3.01 instructions.  Specifically,
	it checks the word and prefixed instructions and some of the Matrix
	Multiply Assist (MMA) instructions.

	The patch has been run on both Power 10 and Power 9 to verify the ISA
	2.06 test case runs on both platforms without errors.  The ISA 3.1 test
	runs without errors on Power 10 and is skipped as expected on Power 9.

	   commit 56262a931b7ca8ee3ec9104bc7e9e0b40cf3d64e

	   Date:   Thu Feb 17 13:43:59 2022 -0700

	       Change how "print/x" displays floating-point value

	       Currently, "print/x" will display a floating-point value by first
	       casting it to an integer type.  This yields weird results like:

	           (gdb) print/x 1.5
	           $1 = 0x1
	        ...
	        Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=16242

	The above change results in 417 regression test failures since the expected
	Power vector register output no longer match.

	This patch updates the expected Altivec floating point register prints to
	the hexadecimal format for both big endian and little endian systems.  The
	patch also fixes a formatting isue with the decimal_vector expected value
	assign statements.

	The expected VSX vector_register1, vector_register1_vr, vector_register2,
	vector_register2_vr variables are updated to include the new float128 entry.
	Additionally, the comment in the vsx expect file about the initialization
	of the vs registers is updated.

	The patch has been tested on Power 10, Power 8 LE and Power 8 BE.

	gdb/infrun: assert !step_over_info_valid_p in restart_threads
	While working in gdb/infrun.c:restart_threads, I was wondering what are
	the preconditions to call the function.  It seems to me that
	!step_over_info_valid_p should be a precondition (i.e. if we are doing
	an inline step over breakpoint, we do not want to resume non stepping
	threads as one of them might miss the breakpoint which is temporally
	disabled).

	To convince myself that this is true, I have added an assertion to
	enforce this, and got one regression in the testsuite:

	    FAIL: gdb.base/step-over-syscall.exp: vfork: displaced=off: single step over vfork (GDB internal error)

	This call to restart_threads originates from handle_vfork_done which
	does not check if a step over is active when restarting other threads:

	    if (target_is_non_stop_p ())
	      {
	        scoped_restore_current_thread restore_thread;

	        insert_breakpoints ();
	        restart_threads (event_thread, event_thread->inf);
	        start_step_over ();
	      }

	In this patch, I propose to:
	- Call start_step_over before restart_threads.  If a step over is already
	  in progress (as it is the case in the failing testcase),
	  start_step_over return immediately, and there is no point in restarting
	  all threads just to stop them right away for a step over breakpoint.
	- Only call restart_threads if no step over is in progress at this
	  point.

	In this patch, I also propose to keep the assertion in restart_threads
	to help enforce this precondition, and state it explicitly.

	I have also checked all other places which call restart_threads, and
	they all seem to check that there is no step over currently active
	before doing the call.

	As for infrun-related things, I am never completely sure I did not miss
	something.  So as usual, all feedback and thoughts are very welcome.

	Tested on x86_64-linux-gnu.

	      gdb: unbuffer all input streams when not using readline

	Issues were reported with some MS-Windows hosts, see the thread
	starting here:

	  https://sourceware.org/pipermail/gdb-patches/2022-March/187004.html

	Filed in bugzilla as: PR mi/29002

	The problem seems to be that calling setbuf on terminal file handles
	is not always acceptable, see this mail for more details:

	  https://sourceware.org/pipermail/gdb-patches/2022-April/187310.html

	This commit does two things, first moving the setbuf calls out of
	gdb_readline_no_editing_callback so that we don't end up calling
	setbuf so often.

	Then, for MS-Windows hosts, we don't call setbuf for terminals, this
	appears to resolve the issues that have been reported.

	gdb: handle_no_resumed: only update thread list of event target
	When running:

	    $ make check TESTS="gdb.multi/multi-re-run.exp" RUNTESTFLAGS="--target_board=native-gdbserver"

	I get:

	    target remote localhost:2347^M

	    and then try again.^M
	    (gdb) FAIL: gdb.multi/multi-re-run.exp: re_run_inf=1: iter=1: runto: run to all_started

	The test does:

	 - Connect to a remote target with inferior 2, continue and stop on the
	   all_started function
	 - Connect to a separate remote target / GDBserver instance with inferior 1,
	   continue and (expect to) stop on the all_started function

	The failure seen above happens when trying to continue inferior 1.

	What happens is:

	 - GDB tells inferior 1's remote target to continue
	 - We go into fetch_inferior_event, try to get an event at random from
	   the targets
	 - do_target_wait happens to pick inferior 2's target
	 - That target return TARGET_WAITKIND_NO_RESUMED, which makes sense:
	   inferior 2 is stopped, that target has no resumed thread
	 - handle_no_resumed tries to update the thread list of all targets:

	   for (auto *target : all_non_exited_process_targets ())
	     {
	       switch_to_target_no_thread (target);
	       update_thread_list ();
	     }

	 - When trying to update the thread list of inferior 1's target, it hits
	   the "Cannot execute this command while the target is running" error.
	   This target is working in "remote all-stop" mode, and it is currently
	   waiting for a stop reply, so it can't send packets to update the
	   thread list at this time.

	To handle the problem described in the comment in handle_no_resumed, I
	don't think it is necessary to update the thread list of all targets,
	but only the event target.  That comment describes a kind of race
	condition where some target reports a breakpoint hit for a thread and
	then its last remaining resumed thread exits, so sends a "no resumed"
	event.  If we ended up resuming the thread that hit a breakpoint, we
	want to ignore the "no resumed" and carry on.

	But I don't really see why we need to update the thread list on the
	other targets.  I can't really articulate this, it's more a gut feeling,
	maybe I just fail to imagine the situation where this is needed.  But
	here is the patch anyway, so we can discuss it.  The patch changes
	handle_no_resumed to only update the thread list of the event target.
	This fixes the test run shown above.

	The way I originally tried to fix this was to make
	remote_target::update_thread_list return early if the target is
	currently awaiting a stop reply, since there's no way it can update the
	thread list at that time.  But that felt more like papering over the
	problem.  I then thought that we probably shouldn't be asking the target
	to update the thread list unnecessarily.

	Instead, add a linux_process_target::remove_linux_process helper method

	This commit replaces this earlier commit:

	      gdb: work around prompt corruption caused by bracketed-paste-mode

	Please read that commit for a full description of the bug, and why is
	occurs.

	In this commit I extend GDB to use readline's rl_deprep_term_function
	hook to call a new function gdb_rl_deprep_term_function.  From this
	new function we can now print the 'quit' message, this replaces the
	old printing of 'quit' in command_line_handler.  Of course, we only
	print 'quit' in gdb_rl_deprep_term_function when we are handling EOF,
	but thanks to the previous commit (to readline) we now know when this
	is.

	There are two aspects of this commit that are worth further
	discussion, the first is in the new gdb_rl_deprep_term_function
	function.  In here I have used a scoped_restore_tmpl to disable the
	readline global variable rl_eof_found.

	The reason for this is that, in rl_deprep_terminal, readline will
	print an extra '\n' character before printing the escape sequence to
	leave bracketed paste mode.  You might then think that in the
	gdb_rl_deprep_term_function function, we could simply print "quit" and
	rely on rl_deprep_terminal to print the trailing '\n'.  However,
	rl_deprep_terminal only prints the '\n' when bracketed paste mode is
	on.  If the user has turned this feature off, no '\n' is printed.
	This means that in gdb_rl_deprep_term_function we need to print
	"quit" when bracketed paste mode is on, and "quit\n" when bracketed
	paste mode is off.

	We could absolutely do that, no problem, but given we know how
	rl_deprep_terminal is implemented, it's easier (I think) to just
	temporarily clear rl_eof_found, this prevents the '\n' being printed
	from rl_deprep_terminal, and so in gdb_rl_deprep_term_function, we can
	now always print "quit\n" and this works for all cases.

	The second issue that should be discussed is backwards compatibility
	with older versions of readline.  GDB can be built against the system
	readline, which might be older than the version contained within GDB's
	tree.  If this is the case then the system readline might not contain
	the fixes needed to support correctly printing the 'quit' string.

	To handle this situation I have retained the existing code in
	command_line_handler for printing 'quit', however, this code is only
	used now if the version of readline we are using doesn't not include
	the required fixes.  And so, if a user is using an older version of
	readline, and they have bracketed paste mode on, then they will see
	the 'quit' sting printed on the line below the prompt, like this:

	  (gdb)
	  quit

	I think this is the best we can do when someone builds GDB against an
	older version of readline.

	Using a newer version of readline, or the patched version of readline
	that is in-tree, will now give a result like this in all cases:

	  (gdb) quit

	Which is what we want.

	readline: back-port changes needed to properly detect EOF
	This commit is a partial back-port of this upstream readline commit:

	            screen line

	I have only pulled in the parts of this commit that relate to the new
	rl_eof_found global, and the RL_STATE_EOF state flag.  These changes
	are needed in order to fix PR cli/28833, and are discussed in this
	thread to the bug-readline mailing list:

	  https://lists.gnu.org/archive/html/bug-readline/2022-02/msg00021.html

	The above commit is not yet in any official readline release, but my
	hope is that now it has been merged into the readline tree it should
	be safe enough to back port this fix to GDB's tree.

	At some point in the future we will inevitably want to roll forward
	the version of readline that we maintain in the binutils-gdb
	repository.  When that day comes the changes in this commit can be
	replaced with the latest upstream readline code, as I have not changed
	the meaning of this code at all from what is in upstream readline.

	This commit alone does not fix the PR cli/28833 issue, for that see
	the next commit, which changes GDB itself.

	gdb: improved EOF handling when using readline 7
	In this commit:

	  commit a6b413d24ccc5d76179bab866834e11fd6fec294
	  Date:   Fri Mar 11 14:44:03 2022 +0000

	      gdb: work around prompt corruption caused by bracketed-paste-mode

	a change was made to GDB to work around bug PR gdb/28833.  The
	consequence of this work around is that, when bracketed paste mode is
	enabled in readline, and GDB is quit by sending EOF, then the output
	will look like this:

	  (gdb)
	  quit

	The ideal output, which is what we get when bracketed paste mode is
	off, is this:

	  (gdb) quit

	The reason we need to make this change is explained in the original
	commit referenced above.  What isn't mentioned in the above commit, is
	that the change that motivated this work around was only added in
	readline 8, older versions of readline don't require the change.

	In later commits in this series I will add a fix to GDB's in-tree copy
	of readline (this fix is back-ported from upstream readline), and then
	I will change GDB so that, when using the (patched) in-tree readline,
	we can have the ideal output in all cases.

	However, GDB can be built against the system readline.  When this is
	done, and the system readline is version 8, then we will still have to
	use the work around (two line) style output.

	But, if GDB is built against the system readline, and the system
	readline is an older version 7 readline, then there's no reason why we
	can't have the ideal output, after all, readline 7 doesn't include the
	change that we need to work around.

	This commit changes GDB so that, when using readline 7 we get the
	ideal output in all cases.  This change is trivial (a simple check
	against the readline version number) so I think this should be fine to
	include.

	For testing this commit, you need to configure GDB including the
	'--with-system-readline' flag, and build GDB on a system that uses
	readline 7, for example 'Ubuntu 18.04'.  Then run the test
	'gdb.base/eof-exit.exp', you should expect everything to PASS.

	    (gdb) FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left (the program exited)

	I can get it to fail quite reliably by pinning it to a core:

	  $ taskset -c 5 make check TESTS="gdb.threads/fork-plus-threads.exp"

	The previous attempt at fixing this was:

	  https://sourceware.org/pipermail/gdb-patches/2021-October/182846.html

	What we see is part due to a possible unfortunate ordering of events
	given by the kernel, and what could be considered a bug in GDB.

	The test program makes a number of forks, waits them all, then exits.
	Most of the time, GDB will get and process the exit event for inferior 1
	after the exit events of all the children.  But this is not guaranteed.
	After the last child exits and is waited by the parent, the parent can
	exit quickly, such that GDB collects from the kernel the exit events for
	the parent and that child at the same time.  It then chooses one event
	at random, which can be the event for the parent.  This will result in
	the parent appearing to exit before its child.  There's not much we can
	do about it, so I think we have to adjust the test to cope.

	After expect has seen the "exited normally" notification for inferior 1,
	it immediately does an "info thread" that it expects to come back empty.
	But at this point, GDB might not have processed inferior 11's (the last
	child) exit event, so it will look like there is still a thread.  Of
	course that thread is dead, we just don't know it yet.  But that makes
	the "no thread" test fail.  If the test waited just a bit more for the
	"exited normally" notification for inferior 11, then the list of threads
	would be empty.

	So, first change, make the test collect all the "exited normally"
	notifications for all inferiors before proceeding, that should ensure we
	see an empty thread list.  That would fix the first FAIL above.

	However, we would still have the second FAIL, as we expect inferior 11
	to not be there, it should have been deleted automatically.  Inferior 11
	is normally deleted when prune_inferiors is called.  That is called by
	normal_stop, which is only called by fetch_inferior_event only if the
	event thread completed an execution command FSM (thread_fsm).  But the
	FSM for the continue command completed when inferior 1 exited.  At that
	point inferior 11 was not prunable, as it still had a thread.  When
	inferior 11 exits, prune_inferiors is not called.

	I think that can be considered a GDB bug.  From the user point of view,
	there's no reason why in one case inferior 11 would be deleted and not
	in the other case.

	This patch makes the somewhat naive change to call prune_inferiors in
	fetch_inferior_event, so that it is called in this case.  It is placed
	at this particular point in the function so that it is called after the
	user inferior / thread selection is restored.  If it was called before
	that, inferior 11 wouldn't be pruned, because it would still be the
	current inferior.

	I'm sorry about this.  I don't understand how it happened, because I
	definitely built and tested the series on Windows, and I didn't change

	More const use and alloca avoidance in coff-pe-read.c
	This changes another function in coff-pe-read.c to use 'const' more,
	and to avoid the use of alloca by instead using std::string.

	Use std::string in coff-pe-read.c
	coff-pe-read.c uses xsnprintf and alloca, but using std::string is
	better, and just as easy.  In general I think alloca is something to
	be avoided, and unbounded uses especially so.

	Remove a const-removing cast from coff-pe-read.c
	coff-pe-read.c casts away const at one spot, but this is easily
	replaced by calling bfd_get_filename directly in a couple of debugging
	prints.

	Simplify BFD section iteration in coff-pe-read.c
	coff-pe-read.c iterates over BFD sections using bfd_map_over_sections,
	but it's much simpler to use a for-each loop.  This allows for the
	removal of helper functions and types.

	Fix method naming bug in new DWARF indexer
	Pedro pointed out that gdb-add-index is much slower with the new DWARF
	indexer.  He also noticed that, in some cases, the generated
	.gdb_index would have the wrong fully-qualified name for a method.

	I tracked this down to a bug in the indexer.  If a type could have
	methods but was marked as a declaration, the indexer was ignoring it.
	However, this meant that the internal map to find the qualified name
	was not updated for this container.

	Fix for gdb.base/solib-search.exp test.
	The variable right_lib_flags is not being set correctly to define RIGHT.
	The value RIGHT is needed to force the address of the library functions
	lib1_func3 and lib2_func4 to occur at different address in the wrong and
	right libraries.

	With RIGHT defined correctly, functions lib1_func3 and lib2_func4 occur
	at different addresses the test runs correctly on Powerpc.

	The test needs the lib2 addresses to be different in the right and
	wrong cases.  That is the point of introducing function lib2_spacer
	with the ifdef RIGHT compiler directive.

	On Intel, the ARRAY_SIZE of 1 versus 8192 is sufficient to get the
	dynamic linker to move the addresses of the library.  You can also get
	the same effect on PowerPC but you must use a value much larger than
	8192.

	The key thing is that the test was not properly setting RIGHT to
	defined to get the lib2_spacer function on Intel and Powerpc.

	Without the patch, we have the Intel backtrace for the bad libraries:

	backtrace
	#0  break_here () at /home/ ... /gdb/testsuite/gdb.base/solib-search.c:30
	#1  0x00007ffff7fae156 in ?? ()

	#3  0x00007ffff7fbb156 in ?? ()

	#7  0x00007ffff7fbb146 in ?? ()

	#9  0x0000555555555156 in main () at /home/ ... /binutils-gdb/gdb/testsuite/gdb.base/solib-search.c:23
	Backtrace stopped: previous frame inner to this frame (corrupt stack?)
	(gdb) PASS: gdb.base/solib-search.exp: backtrace (with wrong libs) (data collection)

	The backtrace on Intel with the good libraries is:

	backtrace
	#0  break_here () at /.../binutils-gdb/gdb/testsuite/gdb.base/solib-search.c:30
	#1  0x00007ffff7fae156 in lib2_func4 () at /.../binutils-gdb/gdb/testsuite/gdb.base/solib-search-lib2.c:49
	#2  0x00007ffff7fbb156 in lib1_func3 () at /.../gdb.base/solib-search-lib1.c:49
	#3  0x00007ffff7fae146 in lib2_func2 () at /.../testsuite/gdb.base/solib-search-lib2.c:30
	#4  0x00007ffff7fbb146 in lib1_func1 () at /.../gdb.base/solib-search-lib1.c:30
	#5  0x0000555555555156 in main () at /...solib-search.c:23
	(gdb) PASS: gdb.base/solib-search.exp: backtrace (with right libs) (data collection)
	PASS: gdb.base/solib-search.exp: backtrace (with right libs)

	In one case the backtrace is correct and the other it
	is wrong on Intel.  This is due to the fact that the ARRAY_SIZE caused
	the dynamic linker to move the library function addresses around.  I
	believe it has to do with the default size of the data and code
	sections used by the dynamic linker.

	So without the patch the backtrace on PowerPC looks like:

	 backtrace
	#0  break_here () at /.../solib-search.c:30
	#1  0x00007ffff7f007f4 in lib2_func4 () at /.../solib-search-lib2.c:49
	#2  0x00007ffff7f307f4 in lib1_func3 () at /.../solib-search-lib1.c:49
	#3  0x00007ffff7f007ac in lib2_func2 () at /.../solib-search-lib2.c:30
	#4  0x00007ffff7f307ac in lib1_func1 () at /.../solib-search-lib1.c:30
	#5  0x000000001000074c in main () at /.../solib-search.c:23

	for both the good and bad libraries.

	The patch fixes defining RIGHT in solib-search-lib1.c and solib-search-
	lib2.c.  Note, without the patch the lib1_spacer and lib2_spacer
	functions do not show up in the object dump of the Intel or Powerpc
	libraries as it should.  The patch fixes that by making sure RIGHT gets
	defined.

	Now with the patch the backtrace for the bad library on PowerPC looks
	like:

	backtrace
	#0  break_here () at /.../solib-search.c:30
	#1  0x00007ffff7f0083c in __glink_PLTresolve () from /.../solib-search-lib2.so
	Backtrace stopped: frame did not save the PC

	And the backtrace for the good libraries on PowerPC looks like:

	backtrace
	#0  break_here () at /.../solib-search.c:30
	#1  0x00007ffff7f0083c in lib2_func4 () at /.../solib-search-lib2.c:49
	#2  0x00007ffff7f3083c in lib1_func3 () at /.../solib-search-lib1.c:49
	#3  0x00007ffff7f007cc in lib2_func2 () at /.../solib-search-lib2.c:30
	#4  0x00007ffff7f307cc in lib1_func1 () at /.../solib-search-lib1.c:30
	#5  0x000000001000074c in main () at /.../solib-search.c:23
	(gdb) PASS: gdb.base/solib-search.exp: backtrace (with right libs) (data collection)
	PASS: gdb.base/solib-search.exp: backtrace (with right libs)

	The issue then is on Power where the ARRAY_SIZE of 1 versus 8192 is not
	sufficient to cause the dymanic linker to allocate the libraries at
	different addresses.  I don't claim to understand the specifics of how
	the dynamic linker works and what the default size is for the data and
	code sections are.  My guess is by default PowerPC allocates a larger
	data size by default, which is large enough to hold array[8192].  The
	default size of the data section allocated by the dynamic linker on
	Intel is not large enough to hold array[8192] thus causing the code
	section on Intel to have to move when the large array is defined.

	Note on PowerPC, if you make ARRAY_SIZE big enough, then you will cause
	the library addresses to occur at different addresses as the larger
	data section forces the code section to a different address.  That was
	actually my original fix for the program until I spoke with Doug Evans
	who originally wrote the test.  Doug noticed that RIGHT was not getting
	defined as he originally intended in the test.

	With the patch to fix the definition of RIGHT, PowerPC has a bad and a
	good backtrace because the address of lib1_func3 and lib2_func4 both
	move because lib1_spacer and lib2_spacer are now defined
	before lib1_func3 and lib2_func4.

	Without the patch, the lib1_spacer and lib2_spacer function doesn't show
	up in the binary for the correct or incorrect library on Intel or PowerPC.
	With the patch, RIGHT gets defined as originally intended for the test on
	both architectures and lib1_spacer and lib2_spacer function show up in the
	binaries on both architectures changing the other function addresses as
	intended thus causing the test work as intended on PowerPC.

	gdb/testsuite: fix "set temporary breakpoint" DUPLICATEs
	Commit c67f4e538 ("gdb/testsuite: make gdb.ada/mi_prot.exp stop at
	expected location") introduced some DUPLICATEs in MI tests using
	mi_continue_to_line, for example:

	    DUPLICATE: gdb.ada/mi_ref_changeable.exp: mi_continue_to_line: set temporary breakpoint

	These test names were previously differentiated by the location passed
	to mi_continue_to_line.  Since the location can contain a path, that
	commit removed the location from the test name, in favor of a hardcoded
	string "set temporary breakpoint", hence removing the differentiator.

	mi_continue_to_line receives a "test" parameter, containing a test
	name.  Add a "with_test_prefix" with that name, so that all tests
	recorded during mi_continue_to_line have this in their name.

	mi_continue_to_line passes that "test" string to mi_get_stop_line, that
	is a bit superfluous.  mi_get_stop_line only uses that string in case of
	failures (it doesn't record a pass if everything goes fine).  Since it's
	not crucial, just remove it, and adjust all callers.

	Adjust three gdb.mi/mi-var-*.exp tests to use prefixes to differentiate
	the multiple calls to mi_run_inline_test (which calls
	mi_continue_to_line).

	Always use dwarf2_initialize_objfile
	Internally we noticed that some tests would fail like so on Windows:

	warning: Section .debug_aranges in [...] has duplicate debug_info_offset 0x0, ignoring .debug_aranges.

	Debugging showed that, in fact, a second CU was being created at this
	offset.  We tracked this down to the fact that, while the ELF reader
	is careful to re-use the per-BFD data, other readers are not, and
	could re-read the DWARF data multiple times.

	However, since the change to allow an objfile to have multiple "quick
	symbol" implementations, there's no reason for this approach -- it's
	safe and easy for all symbol readers to reuse the per-BFD data when
	reading DWARF.

	This patch implements this idea, simplifying dwarf2_build_psymtabs and
	making it private, and then switching to dwarf2_initialize_objfile as
	the sole way to start the DWARF reader.

	Note that, while I think the call to dwarf2_build_frame_info in
	machoread.c is also obsolete, I haven't attempted to remove it here.

	Note the message mentions the 'p' packet.  This is a regression since
	this commit:

	  commit 8579fd136a614985bd27f20539c7bb7c5a51287d
	  Date:   Mon Nov 8 14:58:46 2021 +0000

	      gdb/gdbsupport: make xstrprintf and xstrvprintf return a unique_ptr

	Before this commit the behaviour was:

	  (gdb) show remote X-packet
	  Support for the `X' packet is auto-detected, currently unknown.

	The problem was caused by a failed attempt to ensure that some
	allocated strings were deleted when GDB exits.  The code in the above
	commit attempted to make use of 'static' to solve this problem,
	however, the solution was just wrong.

	In this new commit I instead allocate a static vector into which all
	the allocated strings are stored, this ensures the strings are
	released when GDB exits (which makes output from tools like valgrind
	cleaner), but each string within the vector can be unique, which fixes
	the regression.

	gdbsupport: add path_join function
	In this review [1], Eli pointed out that we should be careful when
	concatenating file names to avoid duplicated slashes.  On Windows, a
	double slash at the beginning of a file path has a special meaning.  So
	naively concatenating "/"  and "foo/bar" would give "//foo/bar", which
	would not give the desired results.  We already have a few spots doing:

	  if (first_path ends with a slash)
	    path = first_path + second_path
	  else
	    path = first_path + slash + second_path

	In general, I think it's nice to avoid superfluous slashes in file
	paths, since they might end up visible to the user and look a bit
	unprofessional.

	Introduce the path_join function that can be used to join multiple path
	components together (along with unit tests).

	I initially wanted to make it possible to join two absolute paths, to
	support the use case of prepending a sysroot path to a target file path,
	or the prepending the debug-file-directory to a target file path.  But
	the code in solib_find_1 shows that it is more complex than this anyway
	(for example, when the right hand side is a Windows path with a drive
	letter).  So I don't think we need to support that case in path_join.
	That also keeps the implementation simpler.

	Change a few spots to use path_join to show how it can be used.  I
	believe that all the spots I changed are guarded by some checks that
	ensure the right hand side operand is not an absolute path.

	Regression-tested on Ubuntu 18.04.  Built-tested on Windows, and I also
	ran the new unit-test there.

	gdb_spawn_attach_cmdline: use unsupported instead of untested
	In a previous commit (b750766ac96: gdb/testsuite: Introduce and use
	gdb_spawn_attach_cmdline), if gdb_spawn_attach_cmdline cannot have GDB
	attach to the process because of ptrace restrictions (operation not

	gdb.debuginfod/fetch_src_and_symbols.exp: Fix "notice empty URL" test
	The gdb_test_multiple pattern for the "notice empty URL" test in
	gdb.debuginfod/fetch_src_and_symbols.exp misses expecting the prompt.
	Fix it by using -re -wrap.

	Also, by using "confirm off", the message GDB prints if Debuginfod
	downloading is available doesn't contain "Enable debuginfod" any
	longer.  E.g.:

	gdb/testsuite: Introduce and use gdb_spawn_attach_cmdline
	Following a7e6a19e87f3d719ea23c65b580a6d9bca4ccab3 "gdb: testsuite: add
	new gdb_attach to check "attach" command", this commit proposes to
	introduce the gdb_spawn_attach_cmdline helper and use it in
	gdb.base/attach.exp.

	This helper starts GDB and adds the "--pid=$PID" argument.

	Also note that both the original and new implementation use
	gdb_spawn_with_cmdline_opts, which in the end uses default_gdb_spawn.
	This makes sure that we use $INTERNAL_GDBFLAGS, which by default already
	contain "-iex \"set height 0\" -iex \"set width 0\"".  To avoid
	repetition of those arguments, gdb_spawn_attach_cmdline does not repeat
	those arguments.

	To maintain a behavior similat to what gdb.base/attach.exp used to do,
	gdb_spawn_attach_cmdline keeps the -quiet flag.

	Tested on x86_64-gnu-linux

	Replace symbol_symtab with symbol::symtab
	This turns symbol_symtab into a method on symbol.  It also replaces
	symbol_set_symtab with a method.

	Replace symbol_arch with symbol::arch
	This turns symbol_arch into a method on symbol.

	Replace symbol_objfile with symbol::objfile
	This turns symbol_objfile into a method on symbol.

	Remove symbol::aclass_index
	Symbols have an aclass_index method, but this isn't needed, because
	the aclass index isn't useful outside of the symbol implementation.

	Use array_view for symbol_impls
	It seemed to me that using array_view for symbol_impls would give a
	bit more error checking, at least when gdb is built in libstdc++ debug
	mode.

	Add accessors for symbol's artificial field
	For a series I'm experimenting with, it was handy to hide a symbol's
	"artificial" field behind accessors.  This patch is the result.

	Unify the DWARF index holders
	The dwarf2_per_bfd object has a separate field for each possible kind
	of index.  Until an earlier patch in this series, two of these were
	even derived from a common base class, but still had separate slots.
	This patch unifies all the index fields using the common base class
	that was introduced earlier in this series.  This makes it more
	obvious that only a single index can be active at a time, and also
	removes some code from dwarf2_initialize_objfile.

	Add an ad hoc version check to dwarf_scanner_base
	Some generic code in the DWARF reader has a special case for older
	versions of .gdb_index.  This patch adds an ad hoc version check
	method so that these spots can work without specific knowledge of
	which index is in use.

	Simplify version check in dw2_symtab_iter_next
	This simplifies the index versio check in dw2_symtab_iter_next, by
	passing a reference to the index object to this function.  This avoids
	an indirection via the per_bfd object.

	Introduce and use dwarf_scanner_base
	This introduces dwarf_scanner_base, a base class for all the index
	readers in the DWARF code.  Then, it changes both mapped_index_base
	and cooked_index_vector to derive from this new base class.

	Introduce readnow_functions
	This introduces readnow_functions, a new subclass of
	dwarf2_base_index_functions, and changes the DWARF reader to use it.
	This lets us drop the "index is NULL" hack from the gdb index code.

	Remove some "OBJF_READNOW" code from dwarf2_debug_names_index
	The dwarf2_debug_names_index code treats a NULL debug_names_table as
	if it were from OBJF_READNOW.  However, this trick is only done for
	gdb_index, never for debug_names -- see dwarf2_initialize_objfile.

	Let mapped index classes create the quick_symbol_functions object
	This changes the mapped index classes to create the
	quick_symbol_functions objects.  This is a step toward having a more
	abstract interface to mapped indices.

	Give mapped_index_base a virtual destructor
	This changes mapped_index_base to have a virtual destructor, so it can
	be destroyed via its base class.

	Move mapped_index_base to new header file
	This moves mapped_index_base and the helper struct name_component to a
	new header file in gdb/dwarf2/.

	gdb/selftest-arch: Make register_test_foreach_arch generate arch tests lazily
	The register_test_foreach_arch is used to instantiate a given selftest
	for all architectures supported by GDB.  It is used in many _initialize_*
	functions (under initialize_all_files, called by gdb_init).

	Because the call is done during GDB's initialization, and because there
	is no guaranty about the order in which all the _initialize_* functions
	are executed, when register_test_foreach_arch is called, GDB is not
	fully initialized.  Specifically, when a particular initialize function
	is executed, only the architectures registered at that point are listed
	by gdbarch_printable_names.

	As a consequence, the list of selftest effectively executed depends on
	the order the _initialize_* functions are called.  This can be observed
	with the following:

	    $ ./gdb/gdb \
	        -data-directory ./gdb/data-directory \
	        -quiet -batch -ex "maint selftest" 2>&1 \
	        | grep -E "Ran [0-9]+ unit tests"
	    Ran 145 unit tests, 0 failed
	    $ GDB_REVERSE_INIT_FUNCTIONS=1 ./gdb/gdb \
	        -data-directory ./gdb/data-directory \
	        -quiet -batch -ex "maint selftest" 2>&1 \
	        | grep -E "Ran [0-9]+ unit tests"
	    Ran 82 unit tests, 0 failed

	To fix this, make register_test_foreach_arch register a lazy selftest
	generator.  This way when the test generator is eventually executed, all
	architectures are registered and we do not have a dependency on the
	order the initialize functions are executed in.

	x86: don't mistake ordinary immediates for SAE / rounding control
	The way SAE templates are constructed was always puzzling me (including
	the need for separate templates in the first place), and expressing the
	extzra attribute via Imm8 actually has a bad effect: Ordinary immediates
	would also be accepted, leading to an extra byte being added after the
	instruction (i.e. generating bad code). Before re-working this (in
	particular to accept proper Intel syntax there), fix the immediate issue
	by adding the so far missing check.

	x86: VCMPSH is Evex.LLIG
	These were mistakenly flagged as Evex.128. Getting the LLIG status right
	for insns allowing for SAE is a prereq for planned further work.

	x86: drop stray CheckRegSize from VFPCLASSPH
	Like VFPCLASSP{S,D} it has only a single operand allowing multiple
	sizes, hence there are no pairs of operands to check for consistent
	size.

	x86/Intel: test non-legacy VCVT{,U}SI2SH insn forms
	For an unclear reason corresponding AVX512F tests were apparently not
	cloned or used as reference here, and instead the bogus legacy forms of
	the insns (with the embedded rounding specifier not last) were used.

	x86: correct and simplify NOP disassembly
	It's not just REX.W which is ignored with opcode 0x90. The same goes for
	REX.R and REX.X as well as empty REX. None of these are forms of
	"xchg %eax,%eax" (which would mean zero-extending %eax to %rax), so they
	also shouldn't be disassembled this way.

	While there simplify things: A single hook function suffices, thus
	making it unnecessary to keep two expressions in sync. And checking
	ins->address_mode for mode_64bit also is unnecessary, as "rex" can be
	non-zero only in that case anyway.

	gdb/testsuite/dwarf: don't automatically add directory and file entry for DWARF 5
	To support DWARF 5 in the DWARF assembler line tables, we currently copy
	the first user-provided directory and the first user-provided files and
	make them elements at indices 0 in the directory and file name tables.
	That was a sufficient behavior at the time (see commit 44fda089397a
	("[gdb/testsuite] Support .debug_line v5 in dwarf assembler")), but in
	the following patches, I would need to have finer grained control on
	what is generated exactly.  For example, I'd like to generate a DWARF 5 line
	table with just a single file and a single directory.

	Get rid of this behavior, and implement what is suggested in
	44fda089397a: make include_dir return the directory index that can be
	used to refer to that directory entry (based on the DWARF version), and
	use it afterwards.

	Adjust dw2-lines.exp and dw2-prologue-end.exp accordingly.  Their produced
	DWARF5 binaries will change a bit, in that they will now have a single
	directory and file, where they had two before.  But it doesn't change
	the expected GDB behavior.

	Fix C++ cast of derived class to base class
	PR c++/28907 points out that casting from a derived class to a base
	class fails in some situations.  The problem turned out to be a
	missing use of value_embedded_offset.  One peculiarity here is that,
	if you managed to construct a pointer-to-derived with an embedded
	offset of 0, the cast would work -- for example, one of the two new
	tests here passes without the patch.

	This embedded offset stuff is an endless source of bugs.  I wonder if
	it's possible to get rid of it somehow.

	Regression tested on x86-64 Fedora 34.

	gdb/testsuite: make gdb.ada/mi_prot.exp stop at expected location
	This test attempts to run until the line marked "STOP", which is at
	prot.adb:34.  It first runs until the "main" symbol, then tries to place
	a breakpoint by line at line 34, without specifying the source file.  When looking at the logs:

	    -break-insert -t 34^M
	    ^done,bkpt={number="2",type="breakpoint",disp="del",enabled="y",addr="0x0000555555558a6c",func="adafinal",file="/home/simark/build/binutils-gdb-one-target/gdb/testsuite/outputs/gdb.ada/mi_pro    t/b~prot.adb",fullname="/home/simark/build/binutils-gdb-one-target/gdb/testsuite/outputs/gdb.ada/mi_prot/b~prot.adb",line="44",thread-groups=["i1"],times="0",original-location="/home/simark/b    uild/binutils-gdb-one-target/gdb/testsuite/outputs/gdb.ada/mi_prot/b~prot.adb:34"}^M
	    ... continues ...
	     *stopped,reason="breakpoint-hit",disp="del",bkptno="2",frame={addr="0x0000555555558a6c",func="adafinal",args=[],file="/home/simark/build/binutils-gdb-one-target/gdb/testsuite/outputs/gdb.ada/    mi_prot/b~prot.adb",fullname="/home/simark/build/binutils-gdb-one-target/gdb/testsuite/outputs/gdb.ada/mi_prot/b~prot.adb",line="44",arch="i386:x86-64"},thread-id="1",stopped-threads="all",co    re="8"^M

	... we see that the breakpoint is placed in some generated file, not in
	the test source file as we expect.  The problem is that "b main" in Ada
	does not place a breakpoint on the "Ada main", but on some symbol in a
	generated source file.  So when stopped at the "main" symbol, we are not
	stopped in the file that contains the STOP marker at line 34.

	The test passes anyway today, so it doesn't seem to matter that we are
	stopped at an unexpected location.  But it starts failing with this
	patch [1], because b~prot.adb:34 happens to be between two functions, so
	the breakpoint doesn't resolve.

	Fix this by placing the breakpoint at "$srcfile:$line", which works
	regardless of what is the current source file.

	However, this ends up introducing a path in the test name.  Modify
	mi_tbreak and mi_continue_to_line to avoid that.

	gdb/testsuite: add text_segment option to gdb_compile
	LLVM's lld linker doesn't have the "-Ttext-segment" option, but
	"--image-base" can be used instead.

	gdbserver/linux: Access memory even if threads are running
	Similarly to how the native Linux target was changed
	and subsequently reworked in these commits:

	 05c06f318fd9 Linux: Access memory even if threads are running
	 8a89ddbda2ec Avoid /proc/pid/mem races (PR 28065)

	... teach GDBserver to access memory even when the current thread is
	running, by always accessing memory via /proc/PID/mem.

	The existing comment:

	  /* Neither ptrace nor /proc/PID/mem allow accessing memory through a
	     running LWP.  */

	... is incorrect for /proc/PID/mem does allow that.

	Actually, from GDB's perspective, GDBserver could already access
	memory while threads were running, but at the expense of pausing all
	threads for the duration of the memory access, via
	prepare_to_access_memory.  This new implementation does not require
	pausing any thread, thus
	linux_process_target::prepare_to_access_memory /
	linux_process_target::done_accessing_memory become nops.  A subsequent
	patch will remove the whole prepare_to_access_memory infrastructure
	completely.

	The GDBserver linux-low.cc implementation is simpler than GDB's
	linux-nat.c's, because GDBserver always adds the unfollowed vfork/fork
	children to the process list immediately when the fork/vfork event is
	seen out of ptrace.  I.e., there's no need to keep the file descriptor
	stored on a side map, we can store it directly in the process
	structure.

	gdbserver: special case target_write_memory len==0
	The next patch in this series adds a common helper routine for both
	memory reads and writes, like this:

	 static int
	 proc_xfer_memory (CORE_ADDR memaddr, unsigned char *readbuf,
			  const gdb_byte *writebuf, int len)
	 {
	   gdb_assert ((readbuf == nullptr) != (writebuf == nullptr));
	   ...
	 }

	 int
	 linux_process_target::read_memory (CORE_ADDR memaddr,
	                                    unsigned char *myaddr, int len)
	 {
	   return proc_xfer_memory (memaddr, myaddr, nullptr, len);
	 }

	 linux_process_target::write_memory (CORE_ADDR memaddr,
	                                    const unsigned char *myaddr, int len)
	 {
	   return proc_xfer_memory (memaddr, nullptr, myaddr, len);
	 }

	Surprisingly, the assertion fails.  That happens because it can happen
	that target_write_memory is called with LEN==0, due to this in
	gdb/remote.c:

	 /* Determine whether the remote target supports binary downloading.
	    This is accomplished by sending a no-op memory write of zero length
	    to the target at the specified address. (...) */

	 void
	 remote_target::check_binary_download (CORE_ADDR addr)
	 {
	 ...
	       p = rs->buf.data ();
	       *p++ = 'X';
	       p += hexnumstr (p, (ULONGEST) addr);
	       *p++ = ',';
	       p += hexnumstr (p, (ULONGEST) 0);
	       *p++ = ':';
	       *p = '\0';

	In this scenario, in gdbserver's target_write_memory, the "myaddr"
	argument of the_target->write_memory is passed the data() of a local
	gdb::byte_vector (which is a specialized std::vector).  It's valid for
	std::vector::data() to return NULL when the vector is empty.

	This commit adds an early return to target_write_memory to avoid
	target backends having to care about this.  For good measure, do the
	same on the read side, in read_inferior_memory.

	Ignore 0,0 entries in .debug_aranges
	When running the internal AdaCore test suite against the new DWARF
	indexer, I found one regression on RISC-V.  The test in question uses
	--gc-sections, and winds up with an entry in the middle of a
	.debug_aranges that has both address and length of 0.  In this
	scenario, gdb assumes the entries are terminated and then proceeds to
	reject the section because it reads a subsequent entry as if it were a
	header.

	It seems to me that, because each header describes the size of each
	.debug_aranges CU, it's better to simply ignore 0,0 entries and simply
	read to the end.  That is what this patch does.

	I've patched an existing test to provide a regression test for this.

	This patch isn't likely to be useful to many people in the short term,

	(AdaCore uses it, and sent it upstream, but it did not land, I don't

	Implement thread_name for gdbserver
	This changes gdbserver to implement thread_name method.

	Share handle_ms_vc_exception with gdbserver
	Currently, gdb's native Windows target implements the exception-based
	approach for setting thread names, but gdbserver does not.  This patch
	moves handle_ms_vc_exception to the shared nat/windows-nat.c code, as
	preparation for adding this support to gdbserver.

	Move target_read_string to target/target.c
	This moves the two overloads of target_read_string to a new file,
	target/target.c, and updates both gdb and gdbserver to build this.

	Remove the byte order parameter to target_read_string
	target_read_string takes a byte order parameter, but only uses this to
	check whether a given character is zero.  This is readily done without
	requiring the parameter, so remove it.

	Rename read_string
	This renames read_string to be an overload of target_read_string.
	This makes it more consistent for the eventual merger with gdbserver.

	Don't call QUIT in read_string
	read_string does not need to call QUIT, because target_read_memory
	already does.  This change is needed to make string-reading usable by
	gdbserver.

	Fix possible Cygwin build problem
	I noticed that nat/windows-nat.c checks __USEWIDE, but nothing sets it
	there -- I forgot to copy over the definition when making this file.
	This patch tries to fix the problem.  I don't have a Cygwin setup, so

	gdb/testsuite: Fix race in gdb.dwarf2/calling-convention.exp
	Pedro Alves warned me that there is a race in
	gdb.dwarf2/calling-convention.exp making the test sometimes fail on his
	setup.  This can be reliably reproduced using :

	    make check-read1 TESTS="gdb.dwarf2/calling-convention.exp"

	The relevant part of the gdb.log file is:

	    return 35
	    Function 'foo' does not follow the target calling convention.
	    If you continue, setting the return value will probably lead to unpredictable behaviors.
	    Make foo return now? (y or n) PASS: gdb.dwarf2/calling-convention.exp: return 35
	    n
	    Not confirmed
	    (gdb) FAIL: gdb.dwarf2/calling-convention.exp: finish

	The issue is that when doing the test for "return 35", the DejaGnu test
	sends "n" (to tell GDB not to perform the return action) but never
	consumes the "Not confirmed" acknowledgment sent by GDB.  Later, when
	trying to do the next test, DejaGnu tries to match the leftover output
	from the "return" test. As this output is not expected, the test fails.

	Fix by using gdb_test to send the "n" answer and match the confirmation
	and consume all output to the prompt.

	Also do minor adjustments to the main regex:
	  - Remove the leading ".*" which is not required.
	  - Ensure that the "?" from the question is properly escaped.

	Tested on x86_64-gnu-linux, using

	- make check TESTS="gdb.dwarf2/calling-convention.exp"
	- make check-read1 TESTS="gdb.dwarf2/calling-convention.exp"
	- make check-readmore TESTS="gdb.dwarf2/calling-convention.exp"

	Silence -Wmaybe-uninitialized warning from target_waitstatus
	Currently, one use of target_waitstatus yields a warning:

	     target/waitstatus.h: In function 'void stop_all_threads()':
	     target/waitstatus.h:175:13: warning: 'ws.target_waitstatus::m_value' may be used uninitialized in this function [-Wmaybe-uninitialized]
	       175 |     m_value = other.m_value;
		   |     ~~~~~~~~^~~~~~~~~~~~~~~

	This patch silences the warning.  I tried the "volatile member"
	approach that was used for gdb::optional, but that didn't work, so
	this patch simply initializes the member.

	Fix regression on Windows with WOW64
	Internally at AdaCore, we recently started testing a 64-bit gdb
	debugging 32-bit processes.  This failed with gdb head, but not with
	gdb 11.

	The tests fail like this:

	     Starting program: [...].exe
	     warning: Could not load shared library symbols for WOW64_IMAGE_SECTION.
	     Do you need "set solib-search-path" or "set sysroot"?
	     warning: Could not load shared library symbols for WOW64_IMAGE_SECTION.
	     Do you need "set solib-search-path" or "set sysroot"?
	     warning: Could not load shared library symbols for NOT_AN_IMAGE.
	     Do you need "set solib-search-path" or "set sysroot"?
	     warning: Could not load shared library symbols for NOT_AN_IMAGE.
	     Do you need "set solib-search-path" or "set sysroot"?

	After some debugging and bisecting, to my surprise the bug was
	introduced by commit 183be222 ("gdb, gdbserver: make target_waitstatus
	safe").

	The problem occurs in handle_exception.  Previously the code did:

	    -  ourstatus->kind = TARGET_WAITKIND_STOPPED;
	    [...]
		 case EXCEPTION_BREAKPOINT:
	    [...]
	    -	  ourstatus->kind = TARGET_WAITKIND_SPURIOUS;
	    [...]
		   /* FALLTHROUGH */
		 case STATUS_WX86_BREAKPOINT:
		   DEBUG_EXCEPTION_SIMPLE ("EXCEPTION_BREAKPOINT");
	    -      ourstatus->value.sig = GDB_SIGNAL_TRAP;
	    [...]
	    -  last_sig = ourstatus->value.sig;

	However, in the new code, the fallthrough case does:

	    +      ourstatus->set_stopped (GDB_SIGNAL_TRAP);

	... which changes the 'kind' in 'ourstatus' after falling through.

	This patch rearranges the 'last_sig' setting to more closely match
	what was done before (this is probably not strictly needed but also
	seemed harmless), and removes the fall-through in the
	'ignore_first_breakpoint' case when __x86_64__ is defined.

	Reorganize Python events documentation
	This slightly reorganizes the Python events documentation.  It hoists
	the "ThreadEvent" text out of the list of events, where it seemed to
	be misplaced.  It tidies the formatting a little bit (adding some
	vertical space for easier reading in info), fixes a typo, adds some
	missing commas, and fixes an incorrect reference to NewInferiorEvent.

	We explicitly make cooked_index have a default move constructor and

	We don't actually need cooked_index to be movable at the moment, so
	remove those lines.

	Let std::thread check pass even without pthreads
	Currently, the configure check for std::thread relies on pthreads
	existing.  However, this means that if std::thread is implemented for
	a non-pthreads host, then the check will yield the wrong answer.  This
	happened in AdaCore internal builds.  Here, we have this GCC patch:

	    https://gcc.gnu.org/legacy-ml/gcc-patches/2019-06/msg01840.html

	... which adds mingw support to GCC's gthreads implementation, and
	also to std::thread.

	This configure change fixes this problem and enables threading for
	gdb.

	M68K: avoid quadratic slowdlow in label alignment check
	Before the change tc-m68k maintained a list of seen labels.
	Alignment check traversed label list to resolve symbol to label.
	This caused quadratic slowdown as each symbol was checked against

	enabled as DWARF generates many labels.

	The change embeds auxiliary label information right into symbol using

	    $ gcc -DONE=1 -gdwarf-4 -g3  test.c

	It looks like even if the size is 0 (the size of the `entries` vector is
	0), we shouldn't be passing a NULL pointer to memcpy.  And
	`entries.data ()` returns NULL.

	Fix that by using std::vector::insert to insert the items of entries
	into m_entries.  I haven't checked, but it should essentially compile
	down to a memcpy, since the vector elements are trivially copyiable.

	gdb: change subfile::line_vector to an std::vector
	Change this field to an std::vector to facilitate memory management.
	Since the linetable_entry array is copied into the symtab resulting from
	the subfile, it is possible to change it without changing how symtab
	stores the linetable entries (which would be a much larger change).

	There is a small change in buildsym_compunit::record_line to avoid
	accessing a now invalid linetable_entry.  Before this patch, we keep a
	pointer to the last linetable entry, pop it from the vector, and then
	read last->line.  It works with the manually-maintained array, but since
	we now use std::vector::pop_back, I am afraid that it could be flagged
	as an invalid access by the various static / dynamic analysis tools to
	access the linetable_entry object after popping it from the vector.
	Instead, record just the line number in an optional and use it.

	There are substantial changes in xcoffread.c that simplify the code, but
	I can't test them.  I was hesitant to do this change because of that,
	but I decided to send it anyway.  I don't think that an almost dead
	platform should hold back improving the code in the common parts of GDB.

	The changes in xcoffread.c are:

	 - Make arrange_linetable "arrange" the linetable passed as a parameter,
	   instead of returning possibly a new one, possibly the same one.
	 - In the "Process main file's line numbers.", I'm not too sure what
	   happens.  We get the lintable from "main_subfile", "arrange" it, but
	   then assign the result to the current subfile, obtained with
	   get_current_subfile.  I assume that the current subfile is also the
	   main one, so now I just call arrange_linetable on the main subfile's
	   line table.
	 - Remove that weird "Useless if!!!" FIXME comment.  It's been there
	   forever, but the "if" is still there, so I guess the "if" can stay
	   there.

	simply move the members from dwarf2_per_cu_quick_data into
	dwarf2_per_cu_data and remove the "quick" object entirely.

	Delete DWARF psymtab code
	This removes the DWARF psymtab reader.

	Enable the new DWARF indexer
	This patch finally enables the new indexer.  It is left until this
	point in the series to avoid any regressions; in particular, it has to
	come after the changes to the DWARF index writer to avoid this
	problem.

	However, if you experiment with the series, this patch can be moved
	anywhere from the patch to wire in the new reader to this point.
	Moving this patch around is how I got separate numbers for the
	parallelization and background finalization patches.

	In the ongoing performance example, this reduces the time from the
	baseline of 1.598869 to 0.903534.

	Genericize addrmap handling in the DWARF index writer
	This updates the DWARF index writing code to make the addrmap-writing
	a bit more generic.  Now, it can handle multiple maps, and it can work
	using the maps generated by the new indexer.

	Note that the new addrmap_index_data::using_index field will be
	deleted in a future patch, when the rest of the DWARF psymtab code is
	removed.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Change parameters to write_address_map
	To support the removal of partial symtabs from the DWARF index writer,
	this makes a small change to have write_address_map accept the address
	map as a parameter, rather than assuming it always comes from the
	per-BFD object.

	Change the key type in psym_index_map
	In order to change the DWARF index writer to avoid partial symtabs,
	this patch changes the key type in psym_index_map (and renames that
	type as well).  Using the dwarf2_per_cu_data as the key makes it
	simpler to reuse this code with the new indexer.

	Rename write_psymtabs_to_index
	We'll be removing all the psymtab code from the DWARF reader.  As a
	preparatory step, this renames write_psymtabs_to_index to avoid the
	"psymtab" name.

2022-04-12  Tom Tromey  <tom@tromey.com>

	"Finalize" the DWARF index in the background
	After scanning the CUs, the DWARF indexer merges all the data into a
	single vector, canonicalizing C++ names as it proceeds.  While not
	necessarily single-threaded, this process is currently done in just
	one thread, to keep memory costs lower.

	However, this work is all done without reference to any data outside
	of the indexes.  This patch improves the apparent performance of GDB
	by moving it to the background.  All uses of the index are then made
	to wait for this process to complete.

	In our ongoing example, this reduces the scanning time on gdb itself
	to 0.173937 (wall).  Recall that before this patch, the time was
	0.668923; and psymbol reader does this in 1.598869.  That is, at the
	end of this series, we see about a 10x speedup.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Parallelize DWARF indexing
	This parallelizes the new DWARF indexer.  The indexer's storage was
	designed so that each storage object and each indexer is fully
	independent.  This setup makes it simple to scan different CUs
	independently.

	This patch creates a new cooked index storage object per thread, and
	then scans a subset of all the CUs in each such thread, using gdb's
	existing thread pool.

	In the ongoing "gdb gdb" example, this patch reduces the wall time
	down to 0.668923, from 0.903534.  (Note that the 0.903534 is the time
	for the new index -- that is, when the "enable the new index" patch is
	rebased to before this one.  However, in the final series, that patch
	appears toward the end.  Hopefully this isn't too confusing.)

2022-04-12  Tom Tromey  <tom@tromey.com>

	Pre-read DWARF section data
	Because BFD is not thread-safe, we need to be sure that any section
	data that is needed is read before trying to do any DWARF indexing in
	the background.

	This patch takes a simple approach to this -- it pre-reads the
	"info"-related sections.  This is done for the main file, but also any
	auxiliary files as well, such as the DWO file.

	This patch could be perhaps enhanced by removing some now-redundant
	calls to dwarf2_section_info::read.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Introduce thread-safe handling for complaints
	This introduces a new class that can be used to make the "complaint"
	code thread-safe.  Instantiating the class installs a new handler that
	collects complaints, and then prints them all when the object is
	destroyed.

	This approach requires some locks.  I couldn't think of a better way
	to handle this, though, because the I/O system is not thread-safe.

	It seemed to me that only GDB developers are likely to enable
	complaints, and because the complaint macro handle this case already
	(before any locks are required), I reasoned that any performance
	degradation that would result here would be fine.

	As an aside about complaints -- are they useful at all?  I just ignore
	them, myself, since mostly they seem to indicate compiler problems
	that can't be solved in the GDB world anyway.  I'd personally prefer
	them to be in a separate tool, like a hypothetical 'dwarflint'.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Wire in the new DWARF indexer
	This wires the new DWARF indexer into the existing reader code.  That
	is, this patch makes the modification necessary to enable the new
	indexer.  It is not actually enabled by this patch -- that will be
	done later.

	I did a bit of performance testing for this patch and a few others.  I
	copied my built gdb to /tmp, so that each test would be done on the
	same executable.  Then, each time, I did:

	    $ ./gdb -nx
	    (gdb) maint time 1
	    (gdb) file /tmp/gdb

	This patch is the baseline and on one machine came in at 1.598869 wall
	time.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Implement quick_symbol_functions for cooked DWARF index
	This implements quick_symbol_functions for the cooked DWARF index.
	This is the code that interfaces between the new index and the rest of
	gdb.  Cooked indexes still aren't created by anything.

	For the most part this is straightforward.  It shares some concepts
	with the existing DWARF indices.  However, because names are stored
	pre-split in the cooked index, name lookup here is necessarily
	different; see expand_symtabs_matching for the gory details.

2022-04-12  Tom Tromey  <tom@tromey.com>

	The new DWARF indexer
	This patch adds the code to index DWARF.  This is just the scanner; it
	reads the DWARF and constructs the index, but nothing calls it yet.

	The indexer is split into two parts: a storage object and an indexer
	object.  This is done to support the parallelization of this code -- a
	future patch will create a single storage object per thread.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Introduce the new DWARF index class
	This patch introduces the new DWARF index class.  It is called
	"cooked" to contrast against a "raw" index, which is mapped from disk
	without extra effort.

	Nothing constructs a cooked index yet.  The essential idea here is
	that index entries are created via the "add" method; then when all the
	entries have been read, they are "finalize"d -- name canonicalization
	is performed and the entries are added to a sorted vector.

	Entries use the DWARF name (DW_AT_name) or linkage name, not the full
	name as is done for partial symbols.

	These two facets -- the short name and the deferred canonicalization
	-- help improve the performance of this approach.  This will become
	clear in later patches, when parallelization is added.

	Some special code is needed for Ada, because GNAT only emits mangled
	("encoded", in the Ada lingo) names, and so we reconstruct the
	hierarchical structure after the fact.  This is also done in the
	finalization phase.

	One other aspect worth noting is that the way the "main" function is
	found is different in the new code.  Currently gdb will notice
	DW_AT_main_subprogram, but won't recognize "main" during reading --
	this is done later, via explicit symbol lookup.  This is done
	differently in the new code so that finalization can be done in the
	background without then requiring a synchronization to look up the
	symbol.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Update skip_one_die for new abbrev properties
	This updates skip_one_die to speed it up in the cases where either
	sibling_offset or size_if_constant are set.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Statically examine abbrev properties
	The new DIE scanner works more or less along the lines indicated by
	the text for the .debug_names section, disregarding the bugs in the
	specification.

	While working on this, I noticed that whether a DIE is interesting is
	a static property of the DIE's abbrev.  It also turns out that many
	abbrevs imply a static size for the DIE data, and additionally that
	for many abbrevs, the sibling offset is stored at a constant offset
	from the start of the DIE.

	This patch changes the abbrev reader to analyze each abbrev and stash
	the results on the abbrev.  These combine to speed up the new indexer.
	If the "interesting" flag is false, GDB knows to skip the DIE
	immediately.  If the sibling offset is statically known, skipping can
	be done without reading any attributes; and in some other cases, the
	DIE can be skipped using simple arithmetic.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Introduce DWARF abbrev cache
	The replacement for the DWARF psymbol reader works in a somewhat
	different way.  The current reader reads and stores all the DIEs that
	might be interesting.  Then, if it is missing a DIE, it re-scans the
	CU and reads them all.  This approach is used for both intra- and
	inter-CU references.

	I instrumented the partial DIE hash to see how frequently it was used:

	    [  0] -> 1538165
	    [  1] ->    4912
	    [  2] ->   96102
	    [  3] ->     175
	    [  4] ->     244

	That is, most DIEs are never used, and some are looked up twice -- but
	this is just an artifact of the implementation of
	partial_die_info::fixup, which may do two lookups.

	Based on this, the new implementation doesn't try to store any DIEs,
	but instead just re-scans them on demand.  In order to do this,
	though, it is convenient to have a cache of DWARF abbrevs.  This way,
	if a second CU is needed to resolve an inter-CU reference, the abbrevs
	for that CU need only be computed a single time.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Add "fullname" handling to file_and_directory
	This changes the file_and_directory object to be able to compute and
	cache the "fullname" in the same way that is done by other code, like
	the psymtab reader.

	Specialize std::hash for gdb_exception
	This adds a std::hash specialization for gdb_exception.  This lets us
	store these objects in a hash table, which is used later in this
	series to de-duplicate the exception output from multiple threads.

	Return vector of results from parallel_for_each
	This changes gdb::parallel_for_each to return a vector of the results.
	However, if the passed-in function returns void, the return type
	remains 'void'.  This functionality is used later, to parallelize the
	new indexer.

	Add batching parameter to parallel_for_each
	parallel_for_each currently requires each thread to process at least
	10 elements.  However, when indexing, it's fine for a thread to handle
	just a single CU.  This patch parameterizes this, and updates the one
	user.

	Refactor build_type_psymtabs_reader
	The new DWARF scanner needs to save the entire cutu_reader object, not
	just parts of it.  In order to make this possible, this patch
	refactors build_type_psymtabs_reader.  This change is done separately
	because it is easy to review in isolation and it helps make the later
	patches smaller.

	Add new overload of dwarf5_djb_hash
	This adds a new overload of dwarf5_djb_hash.  This is used in
	subsequent patches.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Add name splitting
	The new DWARF index code works by keeping names pre-split.  That is,
	rather than storing a symbol name like "a::b::c", the names "a", "b",
	and "c" will be stored separately.

	This patch introduces some helper code to split a full name into its
	components.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Let skip_one_die not skip children
	This patch adds an option to skip_one_die that causes it not to skip
	child DIEs.  This is needed in the new scanner.

	Allow ada_decode not to decode operators
	The new DWARF scanner records names as they appear in DWARF.  However,
	because Ada is unusual, it also decodes the Ada names to synthesize
	package components for them.  In order for this to work out properly,
	gdb also needs a mode where ada_decode can be instructed not to decode
	Ada operator names.  That is what this patch implements.

	Refactor dwarf2_get_pc_bounds
	This changes dwarf2_get_pc_bounds so that it does not directly access
	a psymtab or psymtabs_addrmap.  Instead, both the addrmap and the
	desired payload are passed as parameters.  This makes it suitable to
	be used by the new indexer.

	Add dwarf2_per_cu_data::addresses_seen
	This adds a new member to dwarf2_per_cu_data that indicates whether
	addresses have been seen for this CU.  This is then set by the
	.debug_aranges reader.  The idea here is to detect when a CU does not
	have address information, so that the new indexer will know to do
	extra scanning in that case.

	Fix latent bug in read_addrmap_from_aranges
	Tom de Vries found a failure that we tracked down to a latent bug in
	read_addrmap_from_aranges (previously create_addrmap_from_aranges).
	The bug is that this code can erroneously reject .debug_aranges when
	dwz is in use, due to CUs at duplicate offsets.  Because aranges can't
	refer to a CU coming from the dwz file, the fix is to simply skip such
	CUs in the loop.

	Split create_addrmap_from_aranges
	This patch splits create_addrmap_from_aranges into a wrapper function
	and a worker function.  The worker function is then used in a later
	patch.

2022-04-12  Tom Tromey  <tom@tromey.com>

	Allow thread-pool.h to work without threads
	thread-pool.h requires CXX_STD_THREAD in order to even be included.
	However, there's no deep reason for this, and during review we found
	that one patch in the new DWARF indexer series unconditionally
	requires the thread pool.

	Because the thread pool already allows a task to be run in the calling
	thread (for example if it is configured to have no threads in the
	pool), it seemed straightforward to make this code ok to use when host
	threads aren't available at all.

	This patch implements this idea.  I built it on a thread-less host
	(mingw, before my recent configure patch) and verified that the result
	builds.

	After the thread-pool change, parallel-for.h no longer needs any
	CXX_STD_THREAD checks at all, so this patch removes these as well.

	gas: new_logical_line{,_flags}() can return "void"
	With the sole user of the return value gone, convert the return type to
	void. This in turn allows simplifying another construct, by moving it
	slightly later in the function.

	gas: drop .appfile and .appline
	These were used originally to represent "# <line> <file>" constructs
	inserted by (typically) compilers when pre-processing. Quite some time
	ago they were replaced by .linefile though. Since the original
	directives were never documented, we ought to be able to remove support

	gas: further adjust file/line handling for .macro
	Commit 7992631e8c0b ("gas/Dwarf: improve debug info generation from .irp
	and alike blocks"), while dealing okay with actual assembly source files
	not using .file/.line and alike outside but not inside of .macro, has
	undue effects when the logical file/line pair was already overridden:
	Line numbers would continuously increment while processing the expanded
	macro, while the goal of the PR gas/16908 workaround is to keep the
	expansion associated with the line invoking the macro. However, as soon
	as enough state was overridden _inside_ the macro to cause as_where() to
	no longer fall back top as_where_physical(), honor this by resuming the
	bumping of the logical line number.

	Note that from_sb_is_expansion's initializer was 1 for an unknown
	reason. While renaming the variable and changing its type, also change
	the initializer to "expanding_none", which would have been "0" in the
	original code. Originally the initializer value itself wasn't ever used
	anyway (requiring sb_index != -1), as it necessarily had changed in
	input_scrub_include_sb() alongside setting sb_index to other than -1.

	Strictly speaking input_scrub_insert_line() perhaps shouldn't use
	expanding_none, yet none of the other enumerators fit there either. And
	then strictly speaking that function probably shouldn't exist in the
	first place. It's used only by tic54x.

	gas: further adjust file/line handling for .irp and alike
	Commit 7992631e8c0b ("gas/Dwarf: improve debug info generation from .irp
	and alike blocks"), while dealing okay with actual assembly source files
	not using .file/.line and alike outside but not inside of .irp et al,
	has undue effects when the logical file/line pair was already
	overridden: Line numbers would continuously increment upon every
	iteration, thus potentially getting far off. Furthermore it left it to
	the user to actually insert .file/.line inside such constructs. Note
	though that before aforementioned change things weren't pretty either:
	Diagnostics (and debug info) would be associated with the directive
	terminating the iteration construct, rather than with the actual lines.

	Handle this automatically by simply latching the present line and then
	re-instating coordinates first thing on every iteration; note that the
	file can't change from what was previously pushed on the scrubber's
	state stack, and hence can be taken from there by using a new flavor of
	.linefile (which is far better memory-footprint-wise than recording the
	full path in the inserted directive). (This then leaves undisturbed any
	file/line control occurring in the body of the construct, as these will
	only be seen and processed afterwards.)

	gdb/doc: add section about Fortran intrinsic functions and types
	The earlier version of this document had no sections about the
	available Fortran intrinsic functions or the Fortran builtin types.

	I added two sections 'Fortran intrinsics' and 'Fortran types' to
	document the available Fortran language features.  The subsection
	'Fortran Defaults' has been integrated into the Fortran subsection.

	gdb/fortran: rewrite intrinsic handling and add some missing overloads
	The operators FLOOR, CEILING, CMPLX, LBOUND, UBOUND, and SIZE accept
	(some only with Fortran 2003) the optional parameter KIND.  This
	parameter determines the kind of the associated return value.  So far,
	implementation of this kind parameter has been missing in GDB.
	Additionally, the one argument overload for the CMPLX intrinsic function
	was not yet available.

	This patch adds overloads for all above mentioned functions to the
	Fortran intrinsics handling in GDB.

	It re-writes the intrinsic function handling section to use the helper
	methods wrap_unop_intrinsic/wrap_binop_intrinsic/wrap_triop_intrinsic.
	These methods define the action taken when a Fortran intrinsic function
	is called with a certain amount of arguments (1/2/3). The helper methods
	fortran_wrap2_kind and fortran_wrap3_kind have been added as equivalents
	to the existing wrap and wrap2 methods.

	After adding more overloads to the intrinsics handling, some of the
	operation names were no longer accurate.  E.g. UNOP_FORTRAN_CEILING
	has been renamed to FORTRAN_CEILING as it is no longer a purely unary
	intrinsic function.  This patch also introduces intrinsic functions with
	one, two, or three arguments to the Fortran parser and the
	UNOP_OR_BINOP_OR_TERNOP_INTRINSIC token has been added.

	gdb/fortran: Change GDB print for fortran default types
	Currently, when asking GDB to print the type of a Fortran default type
	such as INTEGER or REAL, GDB will return the default name of that type,
	e.g. "integer"/"real":

	   (gdb) ptype integer
	   type = integer
	   (gdb) ptype real
	   type = real

	For LOGICAL and COMPLEX it would return the actual underlying types

	   (gdb) ptype logical
	   type = logical*4
	   (gdb) ptype complex
	   type = complex*4

	Similarly, GDB would print the default integer type for the underlying
	default type:

	   (gdb) ptype integer*4
	   type = integer
	   (gdb) ptype real*4
	   type = real
	   (gdb) ptype logical
	   type = logical*4
	   (gdb) ptype complex*4
	   type = complex*4

	This is inconsistent and a bit confusing.  Both options somehow indicate
	what the internal underlying type for the default type is - but I think
	the logical/complex version is a bit clearer.

	Consider again:

	   (gdb) ptype integer
	   type = integer

	This indicates to a user that the type of "integer" is Fortran's default
	integer type.  Without examining "ptype integer*4" I would expect, that
	any variable declared integer in the actual code would also fit into a
	GDB integer.  But, since we cannot adapt out internal types to the
	compiler flags used at compile time of a debugged binary, this might be
	wrong.  Consider debugging Fortran code compiled with GNU and e.g. the
	"-fdefault-integer-8" flag.  In this case the gfortran default integer
	would be integer*8 while GDB internally still would use a builtin_integer,
	so an integer of the size of an integer*4 type.  On the other hand having
	GDB print

	   (gdb) ptype integer
	   type = integer*4

	makes this clearer.  I would still be tempted to fit a variable declared
	integer in the code into a GDB integer - but at least ptype would
	directly tell me what is going on.  Note, that when debugging a binary
	compiled with "-fdefault-integer-8" a user will always see the actual
	underlying type of any variable declared "integer" in the Fortran code.
	So having the code

	   program test
	     integer :: a = 5
	     print *, a ! breakpt
	   end program test

	will, when breaking at breakpt print

	   (gdb) ptype var
	   type = integer(kind=4)

	or

	   (gdb) ptype var
	   type = integer(kind=8)

	depending on the compiler flag.

	This patch changes the outputs for the REAL and INTEGER default types to
	actually print the internally used type over the default type name.

	The new behavior for the above examples is:

	   (gdb) ptype integer
	   type = integer*4
	   (gdb) ptype integer*4
	   type = integer*4

	Existing testcases have been adapted to reflect the new behavior.

	gdb/fortran: clean-up Fortran intrinsic types
	The currently implemented intrinsic type handling for Fortran missed some
	tokens and their parsing.  While still not all Fortran type kinds are
	implemented this patch at least makes the currently handled types
	consistent.  As an example for what this patch does, consider the
	intrinsic type INTEGER.  GDB implemented the handling of the
	keywords "integer" and "integer_2" but missed "integer_4" and "integer_8"
	even though their corresponding internal types were already available as
	the Fortran builtin types builtin_integer and builtin_integer_s8.
	Similar problems applied to LOGICAL, REAL, and COMPLEX.  This patch adds
	all missing tokens and their parsing.  Whenever a section containing the
	type handling was touched, it also was reordered to be in a more easy to
	grasp order.  All INTEGER/REAL/LOGICAL/COMPLEX types were grouped
	together and ordered ascending in their size making a missing one more
	easy to spot.

	Before this change GDB would print the following when tyring to use the
	INTEGER keywords:

	   (gdb) set language fortran
	   (gdb) ptype integer*1
	   unsupported kind 1 for type integer
	   (gdb) ptype integer_1
	   No symbol table is loaded.  Use the "file" command.
	   (gdb) ptype integer*2
	   type = integer*2
	   (gdb) ptype integer_2
	   type = integer*2
	   (gdb) ptype integer*4
	   type = integer
	   (gdb) ptype integer_4
	   No symbol table is loaded.  Use the "file" command.
	   (gdb) ptype integer*8
	   type = integer*8
	   (gdb) ptype integer_8
	   No symbol table is loaded.  Use the "file" command.
	   (gdb) ptype integer
	   type = integer

	With this patch all keywords are available and the GDB prints:

	   (gdb) set language fortran
	   (gdb) ptype integer*1
	   type = integer*1
	   (gdb) ptype integer_1
	   type = integer*1
	   (gdb) ptype integer*2
	   type = integer*2
	   (gdb) ptype integer_2
	   type = integer*2
	   (gdb) ptype integer*4
	   type = integer*4
	   (gdb) ptype integer_4
	   type = integer*4
	   (gdb) ptype integer*8
	   type = integer*8
	   (gdb) ptype integer_8
	   type = integer*8
	   (gdb) ptype integer
	   type = integer

	The described changes have been applied to INTEGER, REAL, COMPLEX,
	and LOGICAL. Existing testcases have been adapted to reflect the
	new behavior.  Tests for formerly missing types have been added.

	gdb/fortran: change default logical type to builtin_logical
	According to the Fortran standard, logical is of the size of a
	'single numeric storage unit' (just like real and integer). For
	gfortran, flang and ifx/ifort this storage unit (or the default
	logical type) is of size kind 4, actually occupying 4 bytes of
	storage, and so the default type for logical expressions in
	Fortran should probably also be Logical*4 and not Logical*2.  I
	adapted GDB's behavior to be in line with
	gfortran/ifort/ifx/flang.

2022-04-11  Nils-Christian Kempke  <nils-christian.kempke@intel.com>

	gdb/fortran: fix complex type in Fortran builtin types
	Before this patch things like

	  (gdb) ptype complex*8
	  complex*16
	  (gdb) ptype complex*4
	  complex*8

	were possible in GDB, which seems confusing for a user.  The reason
	is a mixup in the implementation of the Fortran COMPLEX type.  In
	Fortran the "*X" after a type would normally (I don't think this
	is language required) specify the type's size in memory.  For the
	COMPLEX type the kind parameters usually (at least for GNU, Intel, Flang)
	specify not the size of the whole type but the size of the individual
	two REALs used to form the COMPLEX.  Thus, a COMPLEX*4 will usually
	consist of two REAL*4s.  Internally this type was represented by a
	builtin_complex_s8 - but here I think the s8 actually meant the raw
	size of the type.  This is confusing and I renamed the types (e.g.
	builting_complex_s8 became builtin_complex_s4 according to its most
	common useage) and their printed names to their language equivalent.
	Additionally, I added the default COMPLEX type "COMPLEX" being the same
	as a COMPLEX*4 (as is normally the case) and removed the latter.  I added
	a few tests for this new behavior as well.

	The new behavior is

	  (gdb) ptype complex*8
	  complex*8
	  (gdb) ptype complex*4
	  complex*4

	[gdb/testsuite] Fix gdb.dwarf2/dw2-lines.exp for m32 pie
	As reported in PR29043, when running test-case gdb.dwarf2/dw2-lines.exp with

	...
	Breakpoint 2, 0x56555540 in bar ()^M

	(gdb) FAIL: gdb.dwarf2/dw2-lines.exp: cv=2: cdw=32: lv=2: ldw=32: \

	...

	The problem is that the bar breakpoint ends up at an unexpected location
	because:
	- the synthetic debug info is incomplete and doesn't provide line info
	  for the prologue part of the function, so consequently gdb uses the i386
	  port prologue skipper to get past the prologue
	- the i386 port prologue skipper doesn't get past a get_pc_thunk call.

	Work around this in the test-case by breaking on bar_label instead.

	gdb: Avoid undefined shifts, fix Go shifts
	I noticed that a build of GDB with GCC + --enable-ubsan, testing
	against GDBserver showed this GDB crash:

	  (gdb) PASS: gdb.trace/trace-condition.exp: trace: 0x00abababcdcdcdcd << 46 == 0x7373400000000000: advance to trace begin
	  tstart
	  ../../src/gdb/valarith.c:1365:15: runtime error: left shift of 48320975398096333 by 46 places cannot be represented in type 'long int'
	  ERROR: GDB process no longer exists
	  GDB process exited with wait status 269549 exp9 0 1
	  UNRESOLVED: gdb.trace/trace-condition.exp: trace: 0x00abababcdcdcdcd << 46 == 0x7373400000000000: start trace experiment

	The problem is that, "0x00abababcdcdcdcd << 46" is an undefined signed
	left shift, because the result is not representable in the type of the
	lhs, which is signed.  This actually became defined in C++20, and if
	you compile with "g++ -std=c++20 -Wall", you'll see that GCC no longer
	warns about it, while it warns if you specify prior language versions.

	While at it, there are a couple other situations that are undefined
	(and are still undefined in C++20) and result in GDB dying: shifting
	by a negative ammount, or by >= than the bit size of the promoted lhs.
	For the latter, GDB shifts using (U)LONGEST internally, so you have to
	shift by >= 64 bits to see it:

	 $ gdb --batch -q -ex "p 1 << -1"
	 ../../src/gdb/valarith.c:1365:15: runtime error: shift exponent -1 is negative
	 $ # gdb exited

	 $ gdb --batch -q -ex "p 1 << 64"
	 ../../src/gdb/valarith.c:1365:15: runtime error: shift exponent 64 is too large for 64-bit type 'long int'
	 $ # gdb exited

	Also, right shifting a negative value is implementation-defined
	(before C++20, after which it is defined).  For this, I chose to
	change nothing in GDB other than adding tests, as I don't really know
	whether we need to do anything.  AFAIK, most implementations do an
	arithmetic right shift, and it may be we don't support any host or
	target that behaves differently.  Plus, this becomes defined in C++20
	exactly as arithmetic right shift.

	Compilers don't error out on such shifts, at best they warn, so I
	think GDB should just continue doing the shifts anyhow too.

	Thus:

	- Adjust scalar_binop to avoid the undefined paths, either by adding
	  explicit result paths, or by casting the lhs of the left shift to
	  unsigned, as appropriate.

	  For the shifts by a too-large count, I made the result be what you'd
	  get if you split the large count in a series of smaller shifts.
	  Thus:

	     Left shift, positive or negative lhs:

	       V << 64
		 =>  V << 16 << 16 << 16 << 16
		   => 0

	     Right shift, positive lhs:

	       Vpos >> 64
		 =>  Vpos >> 16 >> 16 >> 16 >> 16
		   => 0

	     Right shift, negative lhs:

	       Vneg >> 64
		 =>  Vneg >> 16 >> 16 >> 16 >> 16
		   => -1

	  This is actually Go's semantics (the compiler really emits
	  instructions to make it so that you get 0 or -1 if you have a
	  too-large shift).  So for that language GDB does the shift and
	  nothing else.  For other C-like languages where such a shift is
	  undefined, GDB warns in addition to performing the shift.

	  For shift by a negative count, for Go, this is a hard error.  For
	  other languages, since their compilers only warn, I made GDB warn
	  too.  The semantics I chose (we're free to pick them since this is
	  undefined behavior) is as-if you had shifted by the count cast to
	  unsigned, thus as if you had shifted by a too-large count, thus the
	  same as the previous scenario illustrated above.

	  Examples:

	    (gdb) set language go
	    (gdb) p 1 << 100
	    $1 = 0
	    (gdb) p -1 << 100
	    $2 = 0
	    (gdb) p 1 >> 100
	    $3 = 0
	    (gdb) p -1 >> 100
	    $4 = -1
	    (gdb) p -2 >> 100
	    $5 = -1
	    (gdb) p 1 << -1
	    left shift count is negative

	    (gdb) set language c
	    (gdb) p -2 >> 100
	    warning: right shift count >= width of type
	    $6 = -1
	    (gdb) p -2 << 100
	    warning: left shift count >= width of type
	    $7 = 0
	    (gdb) p 1 << -1
	    warning: left shift count is negative
	    $8 = 0
	    (gdb) p -1 >> -1
	    warning: right shift count is negative
	    $9 = -1

	- The warnings' texts are the same as what GCC prints.

	- Add comprehensive tests in a new gdb.base/bitshift.exp testcase, so
	  that we exercise all these scenarios.

	Pass PKG_CONFIG_PATH down from top-level Makefile
	[Sending to binutils, gdb-patches and gcc-patches, since it touches the
	top-level Makefile/configure]

	I have my debuginfod library installed in a non-standard location
	(/opt/debuginfod), which requires me to set
	PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config.  If I just set it during
	configure:

	    $ PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config ./configure --with-debuginfod
	    $ make

	or

	    $ ./configure --with-debuginfod PKG_CONFIG_PATH=/opt/debuginfod/lib/pkg-config
	    $ make

	Then PKG_CONFIG_PATH is only present (and ignored) during the top-level
	configure.  When running make (which runs gdb's and binutils'
	configure), PKG_CONFIG_PATH is not set, which results in their configure
	script not finding the library:

	    checking for libdebuginfod >= 0.179... no
	    configure: error: "--with-debuginfod was given, but libdebuginfod is missing or unusable."

	Change the top-level configure/Makefile system to capture the value
	passed when configuring the top-level and pass it down to
	subdirectories (similar to CFLAGS, LDFLAGS, etc).

	I don't know much about the top-level build system, so I really don't
	know if I did this correctly.  The changes are:

	 - Use AC_SUBST(PKG_CONFIG_PATH) in configure.ac, so that
	   @PKG_CONFIG_PATH@ gets replaced with the actual PKG_CONFIG_PATH value
	   in config files (i.e. Makefile)
	 - Add a PKG_CONFIG_PATH Makefile variable in Makefile.tpl, initialized
	   to @PKG_CONFIG_PATH@
	 - Add PKG_CONFIG_PATH to HOST_EXPORTS in Makefile.tpl, which are the
	   variables set when running the sub-configures

	I initially added PKG_CONFIG_PATH to flags_to_pass, in Makefile.def, but
	I don't think it's needed.  AFAIU, this defines the flags to pass down
	when calling "make" in subdirectories.  We only need PKG_CONFIG_PATH to
	be passed down during configure.  After that, it's captured in
	gdb/config.status, so even if a "make" causes a re-configure later
	(because gdb/configure has changed, for example), the PKG_CONFIG_PATH
	value will be remembered.

	ChangeLog:

		* configure.ac: Add AC_SUBST(PKG_CONFIG_PATH).
		* configure: Re-generate.
		* Makefile.tpl (HOST_EXPORTS): Pass PKG_CONFIG_PATH.
		(PKG_CONFIG_PATH): New.
		* Makefile.in: Re-generate.

	The test loads the binary in GDB, grabs the address of a symbol, strips
	the binary, reloads it in GDB, runs the program, and then tries to place
	a breakpoint at that address.  The problem is that the binary is built
	as position independent, so the address GDB grabs in the first place
	isn't where the code ends up after running.

	Fix this by linking the binary as non-position-independent.  The
	alternative would be to compute the relocated address where to place the
	breakpoint, but that's not very straightforward, unfortunately.

	I was confused for a while, I was trying to load the binary in GDB
	manually to get the symbol address, but GDB was telling me the symbol
	could not be found.  Meanwhile, it clearly worked in gdb.log.  The thing
	is that GDB strips the binary in-place, so we don't have access to the
	intermediary binary with symbols.  Change the test to output the
	stripped binary to a separate file instead.

	gdb/fortran: print fortran extended types with ptype
	Add the print of the base-class of an extended type to the output of

	for the extended type.

	gdb/fortran: add support for accessing fields of extended types
	Fortran 2003 supports type extension.  This patch allows access
	to inherited members by using their fully qualified name as described
	in the Fortran standard.

	In doing so the patch also fixes a bug in GDB when trying to access the
	members of a base class in a derived class via the derived class' base
	class member.

	This patch fixes PR22497 and PR26373 on GDB side.

	Using the example Fortran program from PR22497

	program mvce
	  implicit none

	  type :: my_type
	     integer :: my_int
	  end type my_type

	  type, extends(my_type) :: extended_type
	  end type extended_type

	  type(my_type) :: foo
	  type(extended_type) :: bar

	  foo%my_int = 0
	  bar%my_int = 1

	  print*, foo, bar

	end program mvce

	and running this with GDB and setting a BP at 17:

	Before:
	(gdb) p bar%my_type
	A syntax error in expression, near `my_type'.
	(gdb) p bar%my_int
	There is no member named my_int.
	(gdb) p bar%my_type%my_int
	A syntax error in expression, near `my_type%my_int'.
	(gdb) p bar
	$1 = ( my_type = ( my_int = 1 ) )

	After:
	(gdb) p bar%my_type
	$1 = ( my_int = 1 )
	(gdb) p bar%my_int
	$2 = 1                 # this line requires DW_TAG_inheritance to work
	(gdb) p bar%my_type%my_int
	$3 = 1
	(gdb) p bar
	$4 = ( my_type = ( my_int = 1 ) )

	In the above example "p bar%my_int" requires the compiler to emit
	information about the inheritance relationship between extended_type
	and my_type which gfortran and flang currently do not de.  The
	respective issue gcc/49475 has been put as kfail.

	gdb/fortran: fix fetching assumed rank array content
	Commit:

	  commit df7a7bdd9766adebc6b117c31bc617d81c1efd43

	      gdb: add support for Fortran's ASSUMED RANK arrays

	Added support for Fortran assumed rank arrays.  Unfortunately, this
	commit contained a bug that means though GDB can correctly calculate
	the rank of an assumed rank array, GDB can't fetch the contents of an
	assumed rank array.

	The history of this patch can be seen on the mailing list here:

	  https://sourceware.org/pipermail/gdb-patches/2022-January/185306.html

	The patches that were finally committed can be found here:

	  https://sourceware.org/pipermail/gdb-patches/2022-March/186906.html

	The original patches did support fetching the array contents, it was
	only the later series that introduced the regression.

	The problem is that when calculating the array rank the result is a
	count of the number of ranks, i.e. this is a 1 based result, 1, 2, 3,
	etc.

	In contrast, when computing the details of any particular rank the
	value passed to the DWARF expression evaluator should be a 0 based
	rank offset, i.e. a 0 based number, 0, 1, 2, etc.

	In the patches that were originally merged, this was not the case, and
	we were passing the 1 based rank number to the expression evaluator,
	e.g. passing 1 when we should pass 0, 2 when we should pass 1, etc.
	As a result the DWARF expression evaluator was reading the
	wrong (undefined) memory, and returning garbage results.

	In this commit I have extended the test case to cover checking the
	array contents, I've then ensured we make use of the correct rank
	value, and extended some comments, and added or adjusted some asserts
	as appropriate.

	gdb/testsuite: add "macros" option to gdb_compile
	Make gdb_compile handle a new "macros" option, which makes it pass the
	appropriate flag to make the compiler include macro information in the
	debug info.  This will help simplify tests using macros, reduce
	redundant code, and make it easier to add support for a new compiler.

	Right now it only handles clang specially (using -fdebug-macro) and
	falls back to -g3 otherwise (which works for gcc).  Other compilers can
	be added as needed.

	There are some tests that are currently skipped if the compiler is nor
	gcc nor clang.  After this patch, the tests will attempt to run (the -g3
	fall back will be used).  That gives a chance to people using other
	compilers to notice something is wrong and maybe add support for their
	compiler.  If it is needed to support a compiler that doesn't have a way
	to include macro information, then we can always introduce a
	"skip_macro_tests" that can be used to skip over them.

	The problem is that the libthread_db message occurs at a location where it's

	Fix this by making the matching more robust:
	- rewrite the regexp such that each annotation is on a single line,

	- add a regexp variable optional_re, that matches all possible optional

	gdb: remove symtab::dirname
	I think the symtab::dirname method is bogus, or at least very
	misleading.  It makes you think that it returns the directory that was
	used to find that symtab's file during compilation (i.e. the directory
	the file refers to in the DWARF line header file table), or the
	directory part of the symtab's filename maybe.  In fact, it returns the
	compilation unit's directory, which is the CWD of the compiler, at
	compilation time.  At least for DWARF, if the symtab's filename is
	relative, it will be relative to that directory.  But if the symtab's
	filename is absolute, then the directory returned by symtab::dirname has
	nothing to do with the symtab's filename.

	Remove symtab::dirname to avoid this confusion, change all users to
	fetch the same information through the compunit.  At least, it will be
	clear that this is a compunit property, not a symtab property.

	gdb: remove reggroup_next and reggroup_prev
	Add a new function gdbarch_reggroups that returns a reference to a

	Make use of this function throughout GDB instead of the existing

	Finally, delete the reggroup_next and reggroup_prev functions.

	Most of these changes are pretty straight forward, using range based
	for loops instead of the old style look using reggroup_next.  There
	are two places where the changes are less straight forward.

	In gdb/python/py-registers.c, the register group iterator needed to
	change slightly.  As the iterator is tightly coupled to the gdbarch, I
	just fetch the register group vector from the gdbarch when needed, and
	use an index counter to find the next item from the vector when
	needed.

	In gdb/tui/tui-regs.c the tui_reg_next and tui_reg_prev functions are
	just wrappers around reggroup_next and reggroup_prev respectively.
	I've just inlined the logic of the old functions into the tui
	functions.  As the tui function had its own special twist (wrap around
	behaviour) I think this is OK.

2022-04-07  Andrew Burgess  <aburgess@redhat.com>

	gdb: always add the default register groups
	There's a set of 7 default register groups.  If we don't add any
	gdbarch specific register groups during gdbarch initialisation, then
	when we iterate over the register groups using reggroup_next and
	reggroup_prev we will make use of these 7 default groups.  See the use
	of default_groups in gdb/reggroups.c for details on this.

	However, if the gdbarch adds its own groups during gdbarch
	initialisation, then these groups will be used in preference to the
	default groups.

	A problem arises though if the particular architecture makes use of
	the target description mechanism.  If the default target
	description(s) (i.e. those internal to GDB that are used when the user
	doesn't provide their own) don't mention any additional register
	groups then the default register groups will be used.

	But if the target description does mention additional groups then the
	default groups are not used, and instead, the groups from the target
	description are used.

	The problem with this is that what usually happens is that the target
	description will mention additional groups, e.g. groups for special
	registers.  Most architectures that use target descriptions work
	around this by adding all (or most) of the default register groups in
	all cases.  See i386_add_reggroups, aarch64_add_reggroups,
	riscv_add_reggroups, xtensa_add_reggroups, and others.

	In this patch, my suggestion is that we should just add the default
	register groups for every architecture, always.  This change is in
	gdb/reggroups.c.

	All the remaining changes are me updating the various architectures to
	not add the default groups themselves.

	So, where will this change be visible to the user?  I think the
	following commands will possibly change:

	* info registers / info all-registers:

	  The user can provide a register group to these commands.  For example,
	  on csky, we previously never added the 'vector' group.  Now, as a
	  default group, this will be available, but (presumably) will not
	  contain any registers.  I don't think this is necessarily a bad
	  thing, there's something to be said for having some consistent
	  defaults available.  There are other architectures that didn't add
	  all 7 of the defaults, which will now have gained additional groups.

	* maint print reggroups

	  This prints the set of all available groups.  As a maintenance
	  command I'm less concerned with the output changing here.
	  Obviously, for the architectures that didn't previously add all the
	  defaults, this list just got bigger.

	* maint print register-groups

	  This prints all the registers, and the groups they are in.  If the
	  defaults were not previously being added then a register (obviously)
	  can't appear in one of the default groups.  Now the groups are
	  available then registers might be in more groups than previously.
	  However, this is again a maintenance command, so I'm less concerned
	  about this changing.

	gdb/tui: fix 'tui reg next/prev' command when data window is hidden
	Start GDB like:

	  $ gdb -q executable
	  (gdb) start
	  (gdb) layout src
	  ... tui windows are now displayed ...
	  (gdb) tui reg next

	At this point the data (register) window should be displayed, but will
	contain the message 'Register Values Unavailable', and at the console
	you'll see the message "unknown register group 'next'".

	The same happens with 'tui reg prev' (but the error message is
	slightly different).

	At this point you can continue to use 'tui reg next' and/or 'tui reg
	prev' and you'll keep getting the error message.

	The problem is that when the data (register) window is first
	displayed, it's current register group is nullptr.  As a consequence
	tui_reg_next and tui_reg_prev (tui/tui-regs.c) will always just return
	nullptr, which triggers an error in tui_reg_command.

	In this commit I change tui_reg_next and tui_reg_prev so that they
	instead return the first and last register group respectively if the
	current register group is nullptr.

	So, after this, using 'tui reg next' will (in the above case) show the
	first register group, while 'tui reg prev' will display the last
	register group.

	gdb/tui: avoid theoretical bug with 'tui reg' command
	While looking at the 'tui reg' command as part of another patch, I
	spotted a theoretical bug.

	The 'tui reg' command takes the name of a register group, but also
	handles partial register group matches, though the partial match has to
	be unique.  The current command logic goes:

	With the code as currently written, if a target description named a
	register group either 'prev' or 'next' then GDB would see this as an
	ambiguous register name, and refuse to switch groups.

	Naming a register group 'prev' or 'next' seems pretty unlikely, but,
	by adding a single else block we can prevent this problem.

	Now, if there's a 'prev' or 'next' register group, the user will not
	be able to select the group directly, the 'prev' and 'next' names will
	always iterate through the available groups instead.  But at least the
	user could select their groups by iteration, rather than direct
	selection.

	  (More stack frames follow...)

	It turns out that the problem is that the async event handler
	mechanism has been invoked, but this has not yet been initialized.

	If we look at gdb_init (in gdb/top.c) we can indeed see the call to
	gdb_init_signals is after the call to initialize_current_architecture.

	If I reorder the calls, moving gdb_init_signals earlier, then the
	initial error is resolved, however, things are still broken.  I now
	see the same "Quit this debugging session? (y or n)" prompt, but when
	I provide an answer and press return GDB immediately crashes.

	So what's going on now?  The next problem is that the call_readline
	field within the current_ui structure is not initialized, and this
	callback is invoked to process the reply I entered.

	The problem is that call_readline is setup as a result of calling
	set_top_level_interpreter, which is called from captured_main_1.
	Unfortunately, set_top_level_interpreter is called after gdb_init is
	called.

	I wondered how to solve this problem for a while, however, I don't
	know if there's an easy "just reorder some lines" solution here.
	Looking through captured_main_1 there seems to be a bunch of
	dependencies between printing various things, parsing config files,
	and setting up the interpreter.  I'm sure there is a solution hiding
	in there somewhere.... I'm just not sure I want to spend any longer
	looking for it.

	So.

	I propose a simpler solution, more of a hack/work-around.  In utils.c
	we already have a function filtered_printing_initialized, this is
	checked in a few places within internal_vproblem.  In some of these
	cases the call gates whether or not GDB will query the user.

	My proposal is to add a new readline_initialized function, which
	checks if the current_ui has had readline initialized yet.  If this is
	not the case then we should not attempt to query the user.

	After this change GDB prints the error message, the backtrace, and
	then aborts (including dumping core).  This actually seems pretty sane
	as, if GDB has not yet made it through the initialization then it
	doesn't make much sense to allow the user to say "no, I don't want to
	quit the debug session" (I think).

	gas/Dwarf: record functions
	To help tools like addr2line looking up function names, in particular
	when dealing with e.g. PE/COFF binaries (linked from ELF objects), where
	there's no ELF symbol table to fall back to, emit minimalistic
	information for functions marked as such and having their size
	specified.

	Notes regarding the restriction to (pure) ELF:
	- I realize this is a layering violation; I don't see how to deal with
	  that in a better way.
	- S_GET_SIZE(), when OBJ_MAYBE_ELF is defined, looks wrong: Unlike
	  S_SET_SIZE() it does not check whether the hook is NULL.
	- symbol_get_obj(), when OBJ_MAYBE_ELF is defined, looks unusable, as
	  its return type can only ever be one object format's type (and this
	  may then not be ELF's).

	The new testcases are limited to x86 because I wanted to include the
	case where function size can't be determined yet at the time Dwarf2 info
	is generated. As .nops gains support by further targets, they could also
	be added here then (with, as necessary, expecations suitably relaxed to
	cover for insn size differences).

	gdb: don't copy entirely optimized out values in value_copy
	Bug 28980 shows that trying to value_copy an entirely optimized out
	value causes an internal error.  The original bug report involves MI and
	some Python pretty printer, and is quite difficult to reproduce, but
	another easy way to reproduce (that is believed to be equivalent) was
	proposed:

	    $ ./gdb -q -nx --data-directory=data-directory -ex "py print(gdb.Value(gdb.Value(5).type.optimized_out()))"
	    /home/smarchi/src/binutils-gdb/gdb/value.c:1731: internal-error: value_copy: Assertion `arg->contents != nullptr' failed.

	This is caused by 5f8ab46bc691 ("gdb: constify parameter of
	value_copy").  It added an assertion that the contents buffer is
	allocated if the value is not lazy:

	  if (!value_lazy (val))
	    {
	      gdb_assert (arg->contents != nullptr);

	This was based on the comment on value::contents, which suggest that
	this is the case:

	  /* Actual contents of the value.  Target byte-order.  NULL or not
	     valid if lazy is nonzero.  */
	  gdb::unique_xmalloc_ptr<gdb_byte> contents;

	However, it turns out that it can also be nullptr also if the value is
	entirely optimized out, for example on exit of
	allocate_optimized_out_value.  That function creates a lazy value, marks
	the entire value as optimized out, and then clears the lazy flag.  But
	contents remains nullptr.

	This wasn't a problem for value_copy before, because it was calling
	value_contents_all_raw on the input value, which caused contents to be
	allocated before doing the copy.  This means that the input value to
	value_copy did not have its contents allocated on entry, but had it
	allocated on exit.  The result value had it allocated on exit.  And that
	we copied bytes for an entirely optimized out value (i.e. meaningless
	bytes).

	From here I see two choices:

	 1. respect the documented invariant that contents is nullptr only and
	    only if the value is lazy, which means making
	    allocate_optimized_out_value allocate contents
	 2. extend the cases where contents can be nullptr to also include
	    values that are entirely optimized out (note that you could still
	    have some entirely optimized out values that do have contents
	    allocated, it depends on how they were created) and adjust
	    value_copy accordingly

	Choice #1 is safe, but less efficient: it's not very useful to allocate
	a buffer for an entirely optimized out value.  It's even a bit less
	efficient than what we had initially, because values coming out of
	allocate_optimized_out_value would now always get their contents
	allocated.

	Choice #2 would be more efficient than what we had before: giving an
	optimized out value without allocated contents to value_copy would
	result in an optimized out value without allocated contents (and the
	input value would still be without allocated contents on exit).  But
	it's more risky, since it's difficult to ensure that all users of the
	contents (through the various_contents* accessors) are all fine with
	that new invariant.

	In this patch, I opt for choice #2, since I think it is a better
	direction than choice #1.  #1 would be a pessimization, and if we go
	this way, I doubt that it will ever be revisited, it will just stay that
	way forever.

	Add a selftest to test this.  I initially started to write it as a
	Python test (since the reproducer is in Python), but a selftest is more
	straightforward.

	Fix for v850e divq instruction
	This is the last of the correctness fixes I've been carrying around for the
	v850.

	Like the other recent fixes, this is another case where we haven't been as
	careful as we should WRT host vs target types.   For the divq instruction
	both operands are 32 bit types.  Yet in the simulator code we convert them
	from unsigned int to signed long by assignment.  So 0xfffffffb (aka -5)
	turns into 4294967291 and naturally that changes the result of our division.

	The fix is simple, insert a cast to int32_t to force interpretation as a
	signed value.

	Testcase for the simulator is included.  It has a trivial dependency on the
	bins patch.

2022-04-06  Jeff Law  <jeffreyalaw@gmail.com>

	Fix "bins" simulation for v850e3v5
	I've been carrying this for a few years.   One test in the GCC testsuite is
	failing due to a bug in the handling of the v850e3v5 instruction "bins".

	When the "bins" instruction specifies a 32bit bitfield size, the simulator
	exhibits undefined behavior by trying to shift a 32 bit quantity by 32 bits.
	In the case of a 32 bit shift, we know what the resultant mask should be.  So
	we can just set it.

	That seemed better than using 1UL for the constant (on a 32bit host unsigned
	long might still just be 32 bits) or needlessly forcing everything to
	long long types.

	Thankfully the case where this shows up is only bins <src>, 0, 32, <dest>
	which would normally be encoded as a simple move.

	Enable ARMv8.1-m PACBTI support
	This set of changes enable support for the ARMv8.1-m PACBTI extensions [1].

	The goal of the PACBTI extensions is similar in scope to that of a-profile
	PAC/BTI (aarch64 only), but the underlying implementation is different.

	One important difference is that the pointer authentication code is stored
	in a separate register, thus we don't need to mask/unmask the return address
	from a function in order to produce a correct backtrace.

	The patch introduces the following modifications:

	- Extend the prologue analyser for 32-bit ARM to handle some instructions
	from ARMv8.1-m PACBTI: pac, aut, pacg, autg and bti. Also keep track of
	return address signing/authentication instructions.

	- Adds code to identify object file attributes that indicate the presence of
	ARMv8.1-m PACBTI (Tag_PAC_extension, Tag_BTI_extension, Tag_PACRET_use and
	Tag_BTI_use).

	- Adds support for DWARF pseudo-register RA_AUTH_CODE, as described in the
	aadwarf32 [2].

	- Extends the dwarf unwinder to track the value of RA_AUTH_CODE.

	- Decorates backtraces with the "[PAC]" identifier when a frame has signed
	the return address.

	- Makes GDB aware of a new XML feature "org.gnu.gdb.arm.m-profile-pacbti". This
	feature is not included as an XML file on GDB's side because it is only
	supported for bare metal targets.

	- Additional documentation.

	gdb: move gdb_disassembly_flag into a new disasm-flags.h file
	While working on the disassembler I was getting frustrated.  Every
	time I touched disasm.h it seemed like every file in GDB would need to
	be rebuilt.  Surely the disassembler can't be required by that many
	parts of GDB, right?

	Turns out that disasm.h is included in target.h, so pretty much every
	file was being rebuilt!

	The only thing from disasm.h that target.h needed is the
	gdb_disassembly_flag enum, as this is part of the target_ops api.

	In this commit I move gdb_disassembly_flag into its own file.  This is
	then included in target.h and disasm.h, after which, the number of
	files that depend on disasm.h is much reduced.

	I also audited all the other includes of disasm.h and found that the
	includes in mep-tdep.c and python/py-registers.c are no longer needed,
	so I've removed these.

	Now, after changing disasm.h, GDB rebuilds much quicker.

	gdb/testsuite: fix intermittent failure in gdb.base/vfork-follow-parent.exp
	Tom de Vries reported some failures in this test:

	    (gdb) FAIL: gdb.base/vfork-follow-parent.exp: resolution_method=schedule-multiple: continue to break_parent (the program exited)

	Here, we continue both the vfork parent and child, since
	schedule-multiple is on.  The child exits, which un-freezes the parent
	and makes an exit event available to GDB.  We expect GDB to consume this
	exit event and present it to the user.  Here, we see that GDB shows the
	parent hitting a breakpoint before showing the child exit.

	Because of the vfork, we know that chronologically, the child exiting
	must have happend before the parent hitting a breakpoint.  However,
	scheduling being what it is, it is possible for the parent to un-freeze
	and exit quickly, such that when GDB pulls events out of the kernel,
	exit events for both processes are available.  And then, GDB may chose
	at random to return the one for the parent first.  This is what I
	imagine what causes the failure shown above.

	We could change the test to expect both possible outcomes, but I wanted
	to avoid complicating the .exp file that way.  Instead, add a variable
	that the parent loops on that we set only after we confirmed the exit of
	the child.  That should ensure that the order is always the same.

	Note that I wasn't able to reproduce the failure, so I can't tell if
	this fix really fixes the problem.

	gdb/testsuite: fix intermittent failures in gdb.mi/mi-cmd-user-context.exp
	I got failures like this once on a CI:

	    frame^M
	    &"frame\n"^M
	    ~"#0  child_sub_function () at /home/jenkins/workspace/binutils-gdb_master_build/arch/amd64/target_board/unix/src/binutils-gdb/gdb/testsuite/gdb.mi/user-selected-context-sync.c:33\n"^M
	    ~"33\t    dummy = !dummy; /* thread loop line */\n"^M
	    ^done^M
	    (gdb) ^M
	    FAIL: gdb.mi/mi-cmd-user-context.exp: frame 1 (unexpected output)

	The problem is that the test expects the following regexp:

	  ".*#0  0x.*"

	And that typically works, when the output of the frame command looks
	like:

	  #0  0x00005555555551bb in child_sub_function () at ...

	Note the lack of hexadecimal address in the failing case.  Whether or
	not the hexadecimal address is printed (roughly) depends on whether the
	current PC is at the beginning of a line.  So depending on where thread
	2 was when GDB stopped it (after thread 1 hit its breakpoint), we can
	get either output.  Adjust the regexps to not expect an hexadecimal
	prefix (0x) but a function name instead (either child_sub_function or
	child_function).  That one is always printed, and is also a good check
	that we are in the frame we expect.

	Note that for test "frame 5", we are showing a pthread frame (on my
	system), so the function name is internal to pthread, not something we
	can rely on.  In that case, it's almost certain that we are not at the
	beginning of a line, or that we don't have debug info, so I think it's
	fine to expect the hex prefix.

	And for test "frame 6", it's ok to _not_ expect a hex prefix (what the
	test currently does), since we are showing thread 1, which has hit a
	breakpoint placed at the beginning of a line.

	When testing this, Tom de Vries pointed out that the current test code
	doesn't ensure that the child threads are in child_sub_function when
	they are stopped.  If the scheduler chooses so, it is possible for the
	child threads to be still in the pthread_barrier_wait or child_function
	functions when they get stopped.  So that would be another racy failure
	waiting to happen.

	The only way I can think of to ensure the child threads are in the
	child_sub_function function when they get stopped is to synchronize the
	threads using some variables instead of pthread_barrier_wait.  So,
	replace the barrier with an array of flags (one per child thread).  Each
	child thread flips its flag in child_sub_function to allow the main
	thread to make progress and eventually hit the breakpoint.

	I copied user-selected-context-sync.c to a new mi-cmd-user-context.c and
	made modifications to that, to avoid interfering with
	user-selected-context-sync.exp.

	Fix qRcmd error code parsing
	Someone at IRC spotted a bug in qRcmd handling. This looks like an oversight
	or it is that way for historical reasons.

	The code in gdb/remote.c:remote_target::rcmd uses isdigit instead of
	isxdigit. One could argue that we are expecting decimal numbers, but further
	below we use fromhex ().

	Update the function to use isxdigit instead and also update the documentation.

	I see there are lots of other cases of undocumented number format for error
	messages, mostly described as NN instead of nn. For now I'll just update
	this particular function.

	gdb: resume ongoing step after handling fork or vfork
	The test introduced by this patch would fail in this configuration, with
	the native-gdbserver or native-extended-gdbserver boards:

	    FAIL: gdb.threads/next-fork-other-thread.exp: fork_func=fork: target-non-stop=auto: non-stop=off: displaced-stepping=auto: i=2: next to for loop

	The problem is that the step operation is forgotten when handling the
	fork/vfork.  With "debug infrun" and "debug remote", it looks like this
	(some lines omitted for brevity).  We do the next:

	    [infrun] proceed: enter
	      [infrun] proceed: addr=0xffffffffffffffff, signal=GDB_SIGNAL_DEFAULT
	      [infrun] resume_1: step=1, signal=GDB_SIGNAL_0, trap_expected=0, current thread [4154304.4154304.0] at 0x5555555553bf

	    [infrun] proceed: exit

	We then handle a fork event:

	    [infrun] fetch_inferior_event: enter
	      [remote] wait: enter
	        [remote] Packet received: T05fork:p3f63ee.3f63ee;06:0100000000000000;07:b08e59f6ff7f0000;10:bf60e8f7ff7f0000;thread:p3f63c0.3f63c6;core:17;
	      [remote] wait: exit
	      [infrun] print_target_wait_results: target_wait (-1.0.0 [process -1], status) =
	      [infrun] print_target_wait_results:   4154304.4154310.0 [Thread 4154304.4154310],
	      [infrun] print_target_wait_results:   status->kind = FORKED, child_ptid = 4154350.4154350.0
	      [infrun] handle_inferior_event: status->kind = FORKED, child_ptid = 4154350.4154350.0

	      [remote] Sending packet: $vCont;c:p3f63c0.-1#73
	    [infrun] fetch_inferior_event: exit

	In the first snippet, we resume the stepping thread with the range-stepping (r)
	vCont command.  But after handling the fork (detaching the fork child), we
	resumed the whole process freely.  The stepping thread, which was paused by
	GDBserver while reporting the fork event, was therefore resumed freely, instead
	of confined to the addresses of the stepped line.  Note that since this
	is a "next", it could be that we have entered a function, installed a
	step-resume breakpoint, and it's ok to continue freely the stepping
	thread, but that's not the case here.  The two snippets shown above were
	next to each other in the logs.

	For the fork case, we can resume stepping right after handling the
	event.

	However, for the vfork case, where we are waiting for the
	external child process to exec or exit, we only resume the thread that
	called vfork, and keep the others stopped (see patch "gdb: fix handling of
	vfork by multi-threaded program" prior in this series).  So we can't
	resume the stepping thread right now.  Instead, do it after handling the
	vfork-done event.

	gdbserver: report correct status in thread stop race condition
	The test introduced by the following patch would sometimes fail in this
	configuration:

	    FAIL: gdb.threads/next-fork-other-thread.exp: fork_func=vfork: target-non-stop=on: non-stop=off: displaced-stepping=auto: i=14: next to for loop

	The test has multiple threads constantly forking or vforking while the
	main thread keep doing "next"s.

	(After writing the commit message, I realized this also fixes a similar
	failure in gdb.threads/forking-threads-plus-breakpoint.exp with the
	native-gdbserver and native-extended-gdbserver boards.)

	As stop_all_threads is called, because the main thread finished its
	"next", it inevitably happens at some point that we ask the remote
	target to stop a thread and wait() reports that this thread stopped with
	a fork or vfork event, instead of the SIGSTOP we sent to try to stop it.

	While running this test, I attached to GDBserver and stopped at
	linux-low.cc:3626.  We can see that the status pulled from the kernel
	for 2742805 is indeed a vfork event:

	    (gdb) p/x w
	    $3 = 0x2057f
	    (gdb) p WIFSTOPPED(w)
	    $4 = true
	    (gdb) p WSTOPSIG(w)
	    $5 = 5
	    (gdb) p/x (w >> 8) & (PTRACE_EVENT_VFORK << 8)
	    $6 = 0x200

	However, the statement at line 3626 overrides that:

	    ourstatus->set_stopped (gdb_signal_from_host (WSTOPSIG (w)));

	OURSTATUS becomes "stopped by a SIGTRAP".  The information about the
	fork or vfork is lost.

	It's then all downhill from there, stop_all_threads eventually asks for
	a thread list update.  That thread list includes the child of that
	forgotten fork or vfork, the remote target goes "oh cool, a new process,
	let's attach to it!", when in fact that vfork child's destiny was to be
	detached.

	My reverse-engineered understanding of the code around there is that the
	if/else between lines 3562 and 3583 (in the original code) makes sure
	OURSTATUS is always initialized (not "ignore").  Either the details are
	already in event_child->waitstatus (in the case of fork/vfork, for
	example), in which case we just copy event_child->waitstatus to
	ourstatus.  Or, if the event is a plain "stopped by a signal" or a
	syscall event, OURSTATUS is set to "stopped", but without a signal
	number.  Lines 3601 to 3629 (in the original code) serve to fill in that
	last bit of information.

	The problem is that when `w` holds the vfork status, the code wrongfully
	takes this branch, because WSTOPSIG(w) returns SIGTRAP:

	  else if (current_thread->last_resume_kind == resume_stop
	       && WSTOPSIG (w) != SIGSTOP)

	The intent of this branch is, for example, when we sent SIGSTOP to try
	to stop a thread, but wait() reports that it stopped with another signal
	(that it must have received from somewhere else simultaneously), say
	SIGWINCH.  In that case, we want to report the SIGWINCH.  But in our
	fork/vfork case, we don't want to take this branch, as the thread didn't
	really stop because it received a signal.  For the non "stopped by a
	signal" and non "syscall signal" cases, we would ideally skip over all
	that snippet that fills in the signal or syscall number.

	The fix I propose is to move this snipppet of the else branch of the
	if/else above.  In addition to moving the code, the last two "else if"
	branches:

	  else if (current_thread->last_resume_kind == resume_stop
		   && WSTOPSIG (w) != SIGSTOP)
	    {
	      /* A thread that has been requested to stop by GDB with vCont;t,
		 but, it stopped for other reasons.  */
	      ourstatus->set_stopped (gdb_signal_from_host (WSTOPSIG (w)));
	    }
	  else if (ourstatus->kind () == TARGET_WAITKIND_STOPPED)
	    ourstatus->set_stopped (gdb_signal_from_host (WSTOPSIG (w)));

	are changed into a single else:

	  else
	    ourstatus->set_stopped (gdb_signal_from_host (WSTOPSIG (w)));

	This is the default path we take if:

	 - W is not a syscall status
	 - W does not represent a SIGSTOP that have sent to stop the thread and
	   therefore want to suppress it

	gdb: fix handling of vfork by multi-threaded program (follow-fork-mode=parent, detach-on-fork=on)
	There is a problem with how GDB handles a vfork happening in a
	multi-threaded program.  This problem was reported to me by somebody not
	using vfork directly, but using system(3) in a multi-threaded program,
	which may be implemented using vfork.

	This patch only deals about the follow-fork-mode=parent,
	detach-on-fork=on case, because it would be too much to chew at once to
	fix the bugs in the other cases as well (I tried).

	The problem
	-----------

	When a program vforks, the parent thread is suspended by the kernel
	until the child process exits or execs.  Specifically, in a
	multi-threaded program, only the thread that called vfork is suspended,
	other threads keep running freely. This is documented in the vfork(2)
	man page ("Caveats" section).

	Let's suppose GDB is handling a vfork and the user's desire is to detach
	from the child. Before detaching the child, GDB must remove the software
	breakpoints inserted in the shared parent/child address space, in case
	there's a breakpoint in the path the child is going to take before
	exec'ing or exit'ing (unlikely, but possible). Otherwise the child could
	hit a breakpoint instruction while running outside the control of GDB,
	which would make it crash.  GDB must also avoid re-inserting breakpoints
	in the parent as long as it didn't receive the "vfork done" event (that
	is, when the child has exited or execed): since the address space is
	shared with the child, that would re-insert breakpoints in the child
	process also. So what GDB does is:

	  1. Receive "vfork" event for the parent
	  2. Remove breakpoints from the (shared) address space and set
	     program_space::breakpoints_not_allowed to avoid re-inserting them
	  3. Detach from the child thread
	  4. Resume the parent
	  5. Wait for and receive "vfork done" event for the parent
	  6. Clean program_space::breakpoints_not_allowed and re-insert
	     breakpoints
	  7. Resume the parent

	Resuming the parent at step 4 is necessary in order for the kernel to
	report the "vfork done" event.  The kernel won't report a ptrace event
	for a thread that is ptrace-stopped.  But the theory behind this is that
	between steps 4 and 5, the parent won't actually do any progress even
	though it is ptrace-resumed, because the kernel keeps it suspended,
	waiting for the child to exec or exit.  So it doesn't matter for that
	thread if breakpoints are not inserted.

	The problem is when the program is multi-threaded.  In step 4, GDB
	resumes all threads of the parent. The thread that did the vfork stays
	suspended by the kernel, so that's fine. But other threads are running
	freely while breakpoints are removed, which is a problem because they
	could miss a breakpoint that they should have hit.

	The problem is present with all-stop and non-stop targets.  The only
	difference is that with an all-stop targets, the other threads are
	stopped by the target when it reports the vfork event and are resumed by
	the target when GDB resumes the parent.  With a non-stop target, the
	other threads are simply never stopped.

	The fix
	-------

	There many combinations of settings to consider (all-stop/non-stop,
	target-non-stop on/off, follow-fork-mode parent/child, detach-on-fork
	on/off, schedule-multiple on/off), but for this patch I restrict the
	scope to follow-fork-mode=parent, detach-on-fork=on.  That's the
	"default" case, where we detach the child and keep debugging the
	parent.  I tried to fix them all, but it's just too much to do at once.
	The code paths and behaviors for when we don't detach the child are
	completely different.

	The guiding principle for this patch is that all threads of the vforking
	inferior should be stopped as long as breakpoints are removed.  This is
	similar to handling in-line step-overs, in a way.

	For non-stop targets (the default on Linux native), this is what
	happens:

	 - In follow_fork, we call stop_all_threads to stop all threads of the
	   inferior
	 - In follow_fork_inferior, we record the vfork parent thread in
	   inferior::thread_waiting_for_vfork_done
	 - Back in handle_inferior_event, we call keep_going, which resumes only
	   the event thread (this is already the case, with a non-stop target).
	   This is the thread that will be waiting for vfork-done.
	 - When we get the vfork-done event, we go in the (new) handle_vfork_done
	   function to restart the previously stopped threads.

	In the same scenario, but with an all-stop target:

	 - In follow_fork, no need to stop all threads of the inferior, the
	   target has stopped all threads of all its inferiors before returning
	   the event.
	 - In follow_fork_inferior, we record the vfork parent thread in
	   inferior::thread_waiting_for_vfork_done.
	 - Back in handle_inferior_event, we also call keep_going.  However, we
	   only want to resume the event thread here, not all inferior threads.
	   In internal_resume_ptid (called by resume_1), we therefore now check
	   whether one of the inferiors we are about to resume has
	   thread_waiting_for_vfork_done set.  If so, we only resume that
	   thread.

	   Note that when resuming multiple inferiors, one vforking and one not
	   non-vforking, we could resume the vforking thread from the vforking
	   inferior plus all threads from the non-vforking inferior.  However,
	   this is not implemented, it would require more work.
	 - When we get the vfork-done event, the existing call to keep_going
	   naturally resumes all threads.

	Testing-wise, add a test that tries to make the main thread hit a
	breakpoint while a secondary thread calls vfork.  Without the fix, the
	main thread keeps going while breakpoints are removed, resulting in a
	missed breakpoint and the program exiting.

	gdb/infrun: add inferior parameters to stop_all_threads and restart_threads
	A following patch will want to stop all threads of a given inferior (as
	opposed to all threads of all inferiors) while handling a vfork, and
	restart them after.  To help with this, add inferior parameters to
	stop_all_threads and restart_threads.  This is done as a separate patch
	to make sure this doesn't cause regressions on its own, and to keep the
	following patches more concise.

	No visible changes are expected here, since all calls sites pass
	nullptr, which should keep the existing behavior.

	gdb: replace inferior::waiting_for_vfork_done with inferior::thread_waiting_for_vfork_done
	The inferior::waiting_for_vfork_done flag indicates that some thread in
	that inferior is waiting for a vfork-done event.  Subsequent patches
	will need to know which thread precisely is waiting for that event.

	Replace the boolean flag (waiting_for_vfork_done) with a thread_info
	pointer (thread_waiting_for_vfork_done).

	I think there is a latent buglet in that waiting_for_vfork_done is
	currently not reset on inferior exec or exit.  I could imagine that if a
	thread in the parent process calls exec or exit while another thread of
	the parent process is waiting for its vfork child to exec or exit, we
	could end up with inferior::waiting_for_vfork_done without a thread
	actually waiting for a vfork-done event anymore.  And since that flag is
	checked in resume_1, things could misbehave there.

	Since the new field points to a thread_info object, and those are
	destroyed on exec or exit, it could be worse now since we could try to
	access freed memory, if thread_waiting_for_vfork_done were to point to a
	stale thread_info.  To avoid this, clear the field in
	infrun_inferior_exit and infrun_inferior_execd.

	gdb/testsuite: fix timeout in server-pipe.exp test
	I noticed that the gdb.server/server-pipe.exp test would sometimes
	timeout when my machine was more heavily loaded.  Turns out the test
	is reading all the shared libraries over GDB's remote protocol, which
	can be slow.

	We avoid this in other tests by setting the sysroot in GDBFLAGS,
	something which is missing from the gdb.server/server-pipe.exp test.

	Fix the timeouts by setting sysroot in GDBFLAGS, after this the shared
	libraries are no longer copied over the remote protocol, and I no
	longer see the test timeout.

	Handle TLS variable lookups when using separate debug files.
	Commit df22c1e5d53c38f38bce6072bb46de240f9e0e2b handled the case that
	a separate debug file was passed as the objfile for a shared library
	to svr4_fetch_objfile_link_map.  However, a separate debug file can
	also be passed for TLS variables in the main executable.  In addition,

	objfile rather than a separate debug file, so pull the code to resolve

	gdb: Add maint set ignore-prologue-end-flag
	The previous patch added support for the DWARF prologue-end flag in line
	table. This flag can be used by DWARF producers to indicate where to
	place breakpoints past a function prologue.  However, this takes
	precedence over prologue analyzers. So if we have to debug a program
	with erroneous debug information, the overall debugging experience will
	be degraded.

	This commit proposes to add a maintenance command to instruct GDB to
	ignore the prologue_end flag.

	gdb: Add support for DW_LNS_set_prologue_end in line-table
	Add support for DW_LNS_set_prologue_end when building line-tables.  This
	attribute can be set by the compiler to indicate that an instruction is
	an adequate place to set a breakpoint just after the prologue of a
	function.

	The compiler might set multiple prologue_end, but considering how
	current skip_prologue_using_sal works, this commit modifies it to accept
	the first instruction with this marker (if any) to be the place where a
	breakpoint should be placed to be at the end of the prologue.

	The need for this support came from a problematic usecase generated by
	hipcc (i.e. clang).  The problem is as follows:  There's a function
	(lets call it foo) which covers PC from 0xa800 to 0xa950.  The body of
	foo begins with a call to an inlined function, covering from 0xa800 to
	0xa94c.   The issue is that when placing a breakpoint at 'foo', GDB
	inserts the breakpoint at 0xa818.  The 0x18 offset is what GDB thinks is
	foo's first address past the prologue.

	Later, when hitting the breakpoint, GDB reports the stop within the
	inlined function because the PC falls in its range while the user
	expects to stop in FOO.

	Looking at the line-table for this location, we have:

	    INDEX  LINE   ADDRESS            IS-STMT
	    [...]
	    14     293    0x000000000000a66c Y
	    15     END    0x000000000000a6e0 Y
	    16     287    0x000000000000a800 Y
	    17     END    0x000000000000a818 Y
	    18     287    0x000000000000a824 Y
	    [...]

	For comparison, let's look at llvm-dwarfdump's output for this CU:

	    Address            Line   Column File   ISA Discriminator Flags

	    [...]

	The main difference we are interested in here is that llvm-dwarfdump's
	output tells us that 0xa800 is an adequate place to place a breakpoint
	past a function prologue.  Since we know that foo covers from 0xa800 to
	0xa94c, 0xa800 is the address at which the breakpoint should be placed
	if the user wants to break in foo.

	This commit proposes to add support for the prologue_end flag in the
	line-program processing.

	The processing of this prologue_end flag is made in skip_prologue_sal,
	before it calls gdbarch_skip_prologue_noexcept.  The intent is that if
	the compiler gave information on where the prologue ends, we should use
	this information and not try to rely on architecture dependent logic to
	guess it.

	The testsuite have been executed using this patch on GNU/Linux x86_64.
	Testcases have been compiled with both gcc/g++ (verison 9.4.0) and
	clang/clang++ (version 10.0.0) since at the time of writing GCC does not
	set the prologue_end marker.  Tests done with GCC 11.2.0 (not over the
	entire testsuite) show that it does not emit this flag either.

	No regression have been observed with GCC or Clang.  Note that when
	using Clang, this patch fixes a failure in
	gdb.opt/inline-small-func.exp.

	gdb/buildsym: Line record use a record flag
	Currently when recording a line entry (with
	buildsym_compunit::record_line), a boolean argument argument is used to
	indicate that the is_stmt flag should be set for this particular record.
	As a later commit will add support for new flags, instead of adding a
	parameter to record_line for each possible flag, transform the current
	is_stmt parameter into a enum flag.  This flags parameter will allow
	greater flexibility in future commits.

	This enum flags type is not propagated into the linetable_entry type as
	this would require a lot of changes across the codebase for no practical
	gain (it currently uses a bitfield where each interesting flag only
	occupy 1 bit in the structure).

	gdb: remove assertion in psymbol_functions::expand_symtabs_matching

	primary symtab of the partial symtab has no symbols.  However,
	psymbol_functions::expand_symtabs_matching asserts that the result of
	psymtab_to_symtab as non-nullptr.

	I caught this assert by trying the CTF symbol reader on a library I

	It contains a single type, and it is skipped by ctf_add_type_cb, because
	an identical type was already seen earlier in this objfile.  As a
	result, no compunit_symtab is created.

	Change psymbol_functions::expand_symtabs_matching to expect that
	psymtab_to_symtab can return nullptr.

	Another possibility would be to make the CTF symbol reader always create
	a compunit_symtab, even if there are no symbols in it (like the DWARF
	parser does), but so far I don't see any advantage in doing so.

	Remove some globals from nat/windows-nat.c
	nat/windows-nat.c has a number of globals that it uses to communicate
	with its clients (gdb and gdbserver).  However, if we ever want the
	Windows ports to be multi-inferior, globals won't work.

	This patch takes a step toward that by moving most nat/windows-nat.c
	globals into a new struct windows_process_info.  Many functions are
	converted to be methods on this object.

	A couple of globals remain, as they are needed to truly be global due
	to the way that the Windows debugging APIs work.

	The clients still have a global for the current process.  That is,
	this patch is a step toward the end goal, but doesn't implement the
	goal itself.

	Add context-sensitive field name completion to Ada parser
	This updates the Ada expression parser to implement context-sensitive
	field name completion.  This is PR ada/28727.

	This is somewhat complicated due to some choices in the Ada lexer --
	it chooses to represent a sequence of "."-separated identifiers as a
	single token, so the parser must partially recreate the completer's
	logic to find the completion word boundaries.

	Despite the minor warts in this patch, though, it is a decent
	improvement.  It's possible that the DWARF reader rewrite will help
	fix the package completion problem pointed out in this patch as well.

	Consolidate single-char tokens in ada-lex.l
	There are two rules in ada-lex.l that match single-character tokens.
	This merges them.

	Also, this removes '.' from the list of such tokens.  '.' is not used

	subsequent completion patches.

	Remove the Ada DOT_ALL token
	The Ada parser has a DOT_ALL token to represent ".all", and another
	token to represent other ".<identifier>" forms.  However, for
	completion it is a bit more convenient to unify these cases, so this
	patch removes DOT_ALL.

	Refactor ada-lex.l:processId
	processId in ada-lex.l is a bit funny -- it uses an "if" and a
	"switch", and a nested loop.  This patch cleans it up a bit, changing
	it to use a boolean flag and a simpler "if".

	Implement completion for Ada attributes
	This adds a completer for Ada attributes.  Some work in the lexer is
	required in order to match end-of-input correctly, as flex does not
	have a general-purpose way of doing this.  (The approach taken here is
	recommended in the flex manual.)

	Refactor expression completion
	This refactors the gdb expression completion code to make it easier to
	add more types of completers.

	In the old approach, just two kinds of completers were supported:
	field names for some sub-expression, or tag names (like "enum
	something").  The data for each kind was combined in single structure,
	"expr_completion_state", and handled explicitly by
	complete_expression.

	In the new approach, the parser state just holds an object that is
	responsible for implementing completion.  This way, new completion
	types can be added by subclassing this base object.

	The structop completer is moved into structop_base_operation, and new
	objects are defined for use by the completion code.  This moves much
	of the logic of expression completion out of completer.c as well.

	In a subsequent patch, it's handy if the 'attributes' array in

	Handle ghost entities in symbol lookup
	Normally, SPARK ghost entities are removed from the executable.
	However, with -gnata, they will be preserved.  In this situation, it's

	the "___ghost_" prefix in the appropriate places.

	bar1's size is 2 while bar2, bar3, bar4's is 1. The behavior of bar1 makes sense
	(generally directives on the new symbol should win) and is relied upon by glibc
	stdio-common/errlist.c:

	```
	        .hidden _sys_errlist_internal
	        .globl  _sys_errlist_internal
	        .type   _sys_errlist_internal, @object
	        .size   _sys_errlist_internal, 1072
	_sys_errlist_internal:

	        .globl __GLIBC_2_1_sys_errlist
	        .set __GLIBC_2_1_sys_errlist, _sys_errlist_internal
	        .type __GLIBC_2_1_sys_errlist, %object
	        .size __GLIBC_2_1_sys_errlist, 125 * (64 / 8)

	// glibc expects that .size __GLIBC_2_1_sys_errlist, 125 * (64 / 8) wins.
	```

	The behavior of bar2/bar3/bar4 seems brittle. To avoid the reordering of the two
	code blocks which will result in the bar3 situation, glibc compiles errlist.c
	with gcc -fno-toplevel-reorder (previously -fno-unit-at-a-time).

	To fix the inconsistency and improve robustness, make bar2/bar3/bar4 match bar1,
	removing the directive order sensitivity.

	There is a pity that `.size dest, 0` is indistinguishable from the case where
	dest is unset, but the compromise seems fine.

	opcodes/i386: partially implement disassembler style support
	This commit adds partial support for disassembler styling in the i386
	disassembler.

	The i386 disassembler collects the instruction arguments into an array
	of strings, and then loops over the array printing the arguments out
	later on.  The problem is that by the time we print the arguments out
	it's not obvious what the type of each argument is.

	Obviously this can be fixed, but I'd like to not do that as part of
	this commit, rather, I'd prefer to keep this commit as small as
	possible to get the basic infrastructure in place, then we can improve
	on this, to add additional styling, in later commits.

	For now then, I think this commit should correctly style mnemonics,
	some immediates, and comments.  Everything else will be printed as
	plain text, which will include most instruction arguments, unless the
	argument is printed as a symbol, by calling the print_address_func
	callback.

	Ignoring colours, there should be no other user visible changes in the
	output of the disassembler in either objdump or gdb.

	opcodes/ChangeLog:

		* disassembler.c (disassemble_init_for_target): Set
		created_styled_output for i386 based targets.
		* i386-dis.c: Changed throughout to use fprintf_styled_func
		instead of fprintf_func.

	objdump/opcodes: add syntax highlighting to disassembler output
	This commit adds the _option_ of having disassembler output syntax
	highlighted in objdump.  This option is _off_ by default.  The new
	command line options are:

	  --disassembler-color=off		# The default.
	  --disassembler-color=color
	  --disassembler-color=extended-color

	I have implemented two colour modes, using the same option names as we
	use of --visualize-jumps, a basic 8-color mode ("color"), and an
	extended 8bit color mode ("extended-color").

	The syntax highlighting requires that each targets disassembler be
	updated; each time the disassembler produces some output we now pass
	through an additional parameter indicating what style should be
	applied to the text.

	As updating all target disassemblers is a large task, the old API is
	maintained.  And so, a user of the disassembler (i.e. objdump, gdb)
	must provide two functions, the current non-styled print function, and
	a new, styled print function.

	I don't currently have a plan for converting every single target
	disassembler, my hope is that interested folk will update the
	disassemblers they are interested in.  But it is possible some might
	never get updated.

	In this initial series I intend to convert the RISC-V disassembler
	completely, and also do a partial conversion of the x86 disassembler.
	Hopefully having the x86 disassembler at least partial converted will
	allow more people to try this out easily and provide feedback.

	In this commit I have focused on objdump.  The changes to GDB at this
	point are the bare minimum required to get things compiling, GDB makes
	no use of the styling information to provide any colors, that will
	come later, if this commit is accepted.

	This first commit in the series doesn't convert any target
	disassemblers at all (the next two commits will update some targets),
	so after this commit, the only color you will see in the disassembler
	output, is that produced from objdump itself, e.g. from
	objdump_print_addr_with_sym, where we print an address and a symbol
	name, these are now printed with styling information, and so will have
	colors applied (if the option is on).

	Finally, my ability to pick "good" colors is ... well, terrible.  I'm
	in no way committed to the colors I've picked here, so I encourage
	people to suggest new colors, or wait for this commit to land, and
	then patch the choice of colors.

	I do have an idea about using possibly an environment variable to
	allow the objdump colors to be customised, but I haven't done anything
	like that in this commit, the color choices are just fixed in the code
	for now.

	The test-case KFAILs some tests.  However, the analysis in the corresponding

	The KFAILs are setup for pre-gcc-12, but apparantly the fix has been
	backported to system compiler 7.5.0, hence the KPASS.

	Fix this by:
	- using an XFAIL instead of a KFAIL

	gdb: add support for Fortran's ASSUMED RANK arrays
	This patch adds a new dynamic property DYN_PROP_RANK, this property is
	read from the DW_AT_rank attribute and stored within the type just
	like other dynamic properties.

	As arrays with dynamic ranks make use of a single
	DW_TAG_generic_subrange to represent all ranks of the array, support
	for this tag has been added to dwarf2/read.c.

	The final piece of this puzzle is to add support in gdbtypes.c so that
	we can resolve an array type with dynamic rank.  To do this the
	existing resolve_dynamic_array_or_string function is split into two,
	there's a new resolve_dynamic_array_or_string_1 core that is
	responsible for resolving each rank of the array, while the now outer
	resolve_dynamic_array_or_string is responsible for figuring out the
	array rank (which might require resolving a dynamic property) and then
	calling the inner core.

	The resolve_dynamic_range function now takes a rank, which is passed
	on to the dwarf expression evaluator.  This rank will only be used in
	the case where the array itself has dynamic rank, but we now pass the
	rank in all cases, this should be harmless if the rank is not needed.

	The only small nit is that resolve_dynamic_type_internal actually
	handles resolving dynamic ranges itself, which now obviously requires
	us to pass a rank value.  But what rank value to use?  In the end I
	just passed '1' through here as a sane default, my thinking is that if
	we are in resolve_dynamic_type_internal to resolve a range, then the
	range isn't part of an array with dynamic rank, and so the range
	should actually be using the rank value at all.

	An alternative approach would be to make the rank value a
	gdb::optional, however, this ends up adding a bunch of complexity to
	the code (e.g. having to conditionally build the array to pass to
	dwarf2_evaluate_property, and handling the 'rank - 1' in
	resolve_dynamic_array_or_string_1) so I haven't done that, but could,
	if people think that would be a better approach.

	Finally, support for assumed rank arrays was only fixed very recently
	in gcc, so you'll need the latest gcc in order to run the tests for
	this.

	Here's an example test program:

	  PROGRAM arank
	    REAL :: a1(10)
	    CALL sub1(a1)

	  CONTAINS

	    SUBROUTINE sub1(a)
	      REAL :: a(..)
	      PRINT *, RANK(a)
	    END SUBROUTINE sub1
	  END PROGRAM arank

	Compiler Version:
	gcc (GCC) 12.0.0 20211122 (experimental)

	Compilation command:
	gfortran assumedrank.f90 -gdwarf-5 -o assumedrank

	Without Patch:

	  gdb -q assumedrank
	  Reading symbols from assumedrank...
	  (gdb) break sub1
	  Breakpoint 1 at 0x4006ff: file assumedrank.f90, line 10.
	  (gdb) run
	  Starting program: /home/rupesh/STAGING-BUILD-2787/bin/assumedrank

	  10       PRINT *, RANK(a)
	  (gdb) print RANK(a)
	  'a' has unknown type; cast it to its declared type

	With patch:

	  gdb -q assumedrank

	gdb/dwarf: pass an array of values to the dwarf evaluator
	When we need to evaluate a DWARF expression in order to resolve some
	dynamic property of a type we call the dwarf2_evaluate_property
	function, which is declared in gdb/dwarf/loc.h and defined in
	gdb/dwarf/loc.c.

	Currently, this function takes (amongst other things) an argument of
	type property_addr_info called addr_stack and a boolean called
	push_initial_value.  When push_initial_value then the top value of
	addr_stack is pushed onto the dwarf expression evaluation stack before
	the expression is evaluated.

	So far this has worked fine, as the only two cases we needed to handle
	are the case the DWARF expression doesn't require the object
	address (what the top of addr_stack represents), and the case where
	the DWARF expression does require the address.

	In the next commit this is going to change.  As we add support for
	Fortran assumed rank arrays, we need to start resolving the dynamic
	properties of arrays.  To do this, we need to push the array rank onto
	the dwarf expression evaluation stack before the expression is
	evaluated.

	This commit is a refactoring commit aimed at making it easier to
	support Fortran assumed rank arrays.  Instead of passing a boolean,
	and using this to decide if we should push the object address or not,
	we instead pass an array (view) of values that should be pushed to the
	dwarf expression evaluation stack.

	In the couple of places where we previously passed push_initial_value
	as true (mostly this was defaulting to false), we now have to pass the
	address from the addr_stack as an item in the array view.

	In the next commit, when we want to handle passing the array rank,
	this will easily be supported too.

	There should be no user visible changes after this commit.

	gdb: small simplification in dwarf2_locexpr_baton_eval
	While examining the dwarf expression evaluator, I noticed that in
	dwarf2_locexpr_baton_eval, whenever push_initial_value is true, the
	addr_stack will never be nullptr.

	This allows for a small cleanup, replacing an if/then/else with an
	assertion.

	There should be no user visible changes after this commit.

	gdb/testsuite: resolve some duplicate test names in gdb.base
	This commit resolves all the duplicate test names that I see in the
	script:

	  gdb.base/attach-pie-misread.exp

	The duplicate names all come from a second call to
	build_executable_own_libs, so in this commit I've places the second
	call inside a with_test_prefix block.

	While I was making this change I've also modified the value being
	passed as the testname for the second build_executable_own_libs call.
	Previously we used ${test}, however, I think this was likely a
	mistake, the 'test' variable is setup for the previous test.  I
	suspect that ${testfile} is a better choice - especially now we have a
	testname prefix.

	As the testname is only used (after various calls) from within
	build_executable_from_specs should the build fail, I don't think this
	change really makes much difference though.

	There should be no change in what is tested after this commit.

	gdb/Makefile.in: move ALLDEPFILES earlier in Makefile.in
	If I do 'make tags' in the gdb build directory, the tags target does
	complete, but I see these warnings:

	  ../../src/gdb/arm.c: No such file or directory
	  ../../src/gdb/arm-get-next-pcs.c: No such file or directory
	  ../../src/gdb/arm-linux.c: No such file or directory

	The reason for this is the ordering of build rules and make variables
	in gdb/Makefile.in, specifically, the placement of the tags related
	rules, and the ALLDEPFILES variable.  The ordering is like this:

	  TAGFILES_NO_SRCDIR = .... $(ALLDEPFILES) ....

	  TAGS: $(TAGFILES_NO_SRCDIR) ....
	          # Recipe uses $(TAGFILES_NO_SRCDIR)

	  tags: TAGS

	  ALLDEPFILES = .....

	When the TAGS rule is parsed TAGFILES_NO_SRCDIR is expanded, which
	then expands ALLDEPFILES, which, at that point in the Makefile is
	undefined, and so expands to the empty string.  As a result TAGS does
	not depend on any file listed in ALLDEPFILES.

	However, when the TAGS recipe is invoked ALLDEPFILES is now defined.
	As a result, all the files in ALLDEPFILES are passed to the etags
	program.

	The ALLDEPFILES references three files, arm.c, arm-get-next-pcs.c, and
	arm-linux.c, which are actually in the gdb/arch/ directory, but, in
	ALLDEPFILES these files don't include the arch/ prefix.  As a result,
	the etags program ends up looking for these files in the wrong
	location.

	As ALLDEPFILES is only used by the TAGS rule, this mistake was not
	previously noticed (the TAGS rule itself was broken until a recent
	commit).

	In this commit I make two changes, first, I move ALLDEPFILES to be
	defined before TAGFILES_NO_SRCDIR, this means that the TAGS rule will
	depend on all the files in ALLDEPFILES.  With this change the TAGS
	rule now breaks complaining that there's no rule to build the 3 files
	mentioned above.

	Next, I have added all *.c files in gdb/arch/ to ALLDEPFILES,
	including their arch/ prefix, and removed the incorrect (missing arch/
	prefix) references.

	With these two changes the TAGS (or tags if you prefer) target now
	builds without any errors or warnings.

	gdb/tui: fair split of delta after a resize
	Currently, in master gdb, when a tui window is changed in size, the
	screen delta is mostly just added to the next available window.  We
	do take care to respect the min/max size, but in most cases, these
	limits are just "the terminal size", and so, we end up placing the
	whole delta on the next window.

	Consider these steps in an 80 column, 24 line terminal:

	  (gdb) tui enable
	  (gdb) layout src
	  (gdb) layout split
	  (gdb) info win
	  Name       Lines Columns Focus
	  src            8      80 (has focus)
	  asm            8      80
	  status         1      80
	  cmd            8      80
	  (gdb) winheight cmd +2
	  (gdb) info win
	  Name       Lines Columns Focus
	  src            6      80 (has focus)
	  asm            8      80
	  status         1      80
	  cmd           10      80

	Notice that initially, the windows were balanced, 8 lines each for the
	major windows.  Then, when the cmd window was adjusted, the extra two
	lines were given to the asm window.

	I think it would be nicer if the delta was spread more evenly over the
	available windows.  In the example above, after the adjustment the
	layout now looks like:

	  (gdb) info win
	  Name       Lines Columns Focus
	  src            7      80 (has focus)
	  asm            7      80
	  status         1      80
	  cmd           10      80

	This is achieved within tui_layout_split::set_size, by just handing
	out the delta in increments of 1 to each window (except for the window
	the user adjusted), until there's no more delta left.  Of course, we
	continue to respect the min/max window sizes.

	gdb/tui: relax restrictions on window max height and width
	This commit removes some arbitrary adjustments made in
	tui_cmd_window::max_height, tui_win_info::max_height, and
	tui_win_info::max_width.

	These member functions all subtract some constant from the theoretical
	maximum height or width.  I've looked back through the history a
	little and can see no real reason why these adjustments should be
	needed, with these adjustments removed all the existing tui tests
	still pass.

	However, retaining these restrictions causes some bugs, consider:

	  (gdb) tui new-layout hsrc {-horizontal src 1 cmd 1} 1

	When this layout is selected with current master, gdb will leave a 4
	line gap at the bottom of the terminal.

	The problem is that the maximum height is restricted, for the cmd
	window, to 4 less than the terminal height.

	By removing this restriction gdb is able to size the windows to the
	complete terminal height, and the layout is done correctly.

	This 4 line restriction is also what prevents this layout from working
	correctly:

	  (gdb) tui new-layout conly cmd 1

	Previously, this layout would present a cmd window only, but there
	would be a 4 line gap at the bottom of the terminal.  This issue was
	mentioned in an earlier commit in this series (when a different bug
	was fixed), but with this commit, the above layout now correctly fills
	the terminal.  The associated test is updated.

	After removing the adjustment in tui_cmd_window::max_height, the
	implementation is now the same as the implementation in the parent
	class tui_win_info, so I've completely removed the max_height call
	from tui_cmd_window.

	gdb/testsuite: some additional tests in gdb.tui/scroll.exp
	This commit just adds an extra check of the src window size prior to
	sending all the commands to gdb.  We also set the cmd window height to
	its existing height, this (obviously) shouldn't change the window

	My main motivation was adding the initial window layout check, the
	winheight and recheck are just extras.  All of these test pass both

	gdb/tui: support placing the cmd window into a horizontal layout
	This commit allows the user to place the cmd window within horizontal
	tui layouts.  Consider this set of steps, carried out in an 80 columns
	by 24 lines terminal, using current master gdb:

	  (gdb) tui new-layout hsrc { -horizontal src 1 cmd 1 } 1 status 1
	  (gdb) tui layout hsrc

	What you end up with is a full width cmd window with the status bar
	beneath.  Where's the src window gone?  We then try:

	  (gdb) info win
	  Name       Lines Columns Focus
	  src           23       3 (has focus)
	  cmd           23      80
	  status         1      80
	  (gdb)

	Something weird has gone on, gdb has overlapped the cmd window with
	the src window.  If we trigger the src window to redraw is content,
	for example, 'list main', then we see corruption in the cmd window as
	the src window overwrites it.

	So, what's going on?

	The problem is some code in tui_layout_split::apply, in tui-layout.c.
	Within 'Step 1', there is a loop that calculates the min/max window
	sizes for all windows within a tui_layout_split.  However, there's a
	special case for the cmd window.

	This special case is trying to have the cmd window retain its current
	size when a layout is re-applied, or a new layout is applied.  This
	makes sense, consider moving from the 'src' layout to the 'asm'
	layout, this looks something like this (status window removed):

	    .-------.         .-------.
	    |  src  |         |  asm  |
	    |-------|  ====>  |-------|
	    |  cmd  |         |  cmd  |
	    '-------'         '-------'

	If the user has gone to the effort of adjusting the cmd window size,
	then, the thinking goes, we shouldn't reset the cmd window size when
	switching layouts like this.

	The problem though, is that when we do a switch more like this:

	    .-----------.         .-----------.
	    |    src    |         |     |     |
	    |-----------|  ====>  | asm | cmd |
	    |    cmd    |         |     |     |
	    '-----------'         '-----------'

	Now retaining the cmd window width makes no sense; the new layout has
	a completely different placement for the cmd window, instead of sizing
	by height, we're now sizing by width.  The existing code doesn't
	understand this though, and tried to retain the full width for the cmd
	window.

	To solve this problem, I propose we introduce the idea of a layout
	"fingerprint".  The fingerprint tries to capture, in an abstract way,
	where the cmd window lives within the layout.

	Only when two layouts have the same fingerprint will we attempt to
	retain the cmd window size.

	The fingerprint for a layout is represented as a string, the string is
	a series of 'V' or 'H' characters, ending with a single 'C'
	character.  The series of 'V' and 'H' characters represent the
	vertical or horizontal layouts that must be passed through to find the
	cmd window.

	Here are a few examples:

	  # This layout is equivalent to the builtin 'src' layout.
	  # Fingerprint: VC
	  tui new-layout example1 src 2 status 0 cmd 1

	  # This layout is equivalent to the builtin 'split' layout.
	  # Fingerprint: VC
	  tui new-layout example2 src 1 asm 1 status 0 cmd 1

	  # This is the same layout that was given at the top.
	  # Fingerprint: VHC
	  tui new-layout hsrc { -horizontal src 1 cmd 1 } 1 status 1

	And so, when switching between example1 and example2, gdb knows that
	the cmd window is, basically, in the same sort of position within the
	layout, and will retain the cmd window size.

	In contrast, when switching to the hsrc layout, gdb understands that
	the position of the cmd window is different, and does not try to
	retain the cmd window size.

2022-04-03  Andrew Burgess  <aburgess@redhat.com>

	gdb/tui: allow cmd window to change size in tui_layout_split::apply
	When we switch layouts we call the tui_layout_split::apply member
	function to reapply the layout, and recalculate all the window sizes.

	One special case is the cmd window, which we try to keep at its
	existing size.

	However, in some cases it is not appropriate to keep the cmd window at
	its existing size.  I will describe two such cases here, in one, we
	want the cmd window to reduce in size, and in the other, we want the
	cmd window to grow in size.

	Try these steps in a 80 columns, by 24 lines terminal:

	  (gdb) tui enable
	  (gdb) layout src
	  (gdb) winheight cmd 20
	  (gdb) layout split

	You should see that the status window is missing from the new layout,
	and that the cmd window has been placed over the border of the asm
	window.  The 'info win' output is:

	  (gdb) info win
	  Name       Lines Columns Focus
	  src            3      80 (has focus)
	  asm            3      80
	  status         1      80
	  cmd           20      80

	Notice that gdb has assigned 27 lines of screen space, even with the
	border overlap between the src and asm windows, this is still 2 lines
	too many.

	The problem here is that after switching layouts, gdb has forced the
	cmd window to retain its 20 line height.  Really, we want the cmd
	window to reduce in height so that the src and asm windows can occupy
	their minimum required space.

	This commit allows this (details on how are below).  After this
	commit, in the above situation, we now see the status window displayed
	correctly, and the 'info win' output is:

	  (gdb) info win
	  Name       Lines Columns Focus
	  src            3      80 (has focus)
	  asm            3      80
	  status         1      80
	  cmd           18      80

	The cmd window has been reduced in size by 2 lines so that everything
	can fit on the screen.

	The second example is one which was discussed in a recent commit,
	consider this case (still in the 80 column, 24 line terminal):

	  (gdb) tui enable
	  (gdb) tui new-layout conly cmd 1
	  (gdb) layout conly
	  (gdb) info win
	  Name       Lines Columns Focus
	  cmd            8      80 (has focus)
	  (gdb)

	This layout only contains a cmd window, which we would expect to
	occupy the entire terminal.  But instead, the cmd window only occupies
	the first 8 lines, and the rest of the terminal is unused!

	The reason is, again, that the cmd window is keeping its previous
	size (8 lines).

	After this commit things are slightly different, the 'info win' output
	is now:

	  (gdb) info win
	  Name       Lines Columns Focus
	  cmd           20      80 (has focus)

	Which is a little better, but why only 20 lines?  Turns out there's
	yet another bug hitting this case.  That bug will be addressed in a
	later commit, so, for now, we're accepting the 20 lines.

	What this commit does is modify the phase of tui_layout_split::apply
	that handles any left over space.  Usually, in "Step 2", each
	sub-layout has a size calculated.  As the size is an integer, then,
	when all sizes are calculated we may have some space left over.

	This extra space is then distributed between all the windows fairly
	until all the space is used up.

	When we consider windows minimum size, or fixed size windows, then it
	is possible that we might try to use more space than is available,
	this was our first example above.  The same code that added extra
	space to the windows, can also be used to reclaim space (in the over
	allocation case) to allow all windows to fit.

	The problem then is the cmd window, which we often force to a fixed
	size.  Inside the loop that handles the allocation of excess space, if
	we find that we have tried every window, and still have space either
	left to give, or we need to claim back more space, then, if the cmd
	window was changed to a fixed size, we can change the cmd window back
	to a non-fixed-size window, and proceed to either give, or take space
	from the cmd window as needed.

2022-04-03  Andrew Burgess  <aburgess@redhat.com>

	gdb/tui: fairer distribution of excess space during apply
	When applying layouts gdb computes the size of each window (or rather,
	each sub-layout within a layout) using integer arithmetic.  As this
	rounds down the results, then, when all sub-layouts are sized, there
	is the possibility that we have some space left over.

	Currently, this space is just assigned to an arbitrary sub-layout.

	This can result in some unbalanced results.  Consider this set of
	steps with current master:

	  (gdb) tui enable
	  (gdb) layout regs
	  (gdb) info win
	  Name       Lines Columns Focus
	  regs           7      80
	  src            9      80 (has focus)
	  status         1      80
	  cmd            8      80

	Notice the weird split between the src and regs windows, the original
	layout specification has these windows given equal weight.  The
	problem is that, with rounding, both the regs and src windows are
	initially sized to 7, the extra 2 lines are then arbitrarily added to
	the src window.

	In this commit, rather than add all the extra space to one single
	window, I instead hand out the extra space 1 line at a time, looping
	over all the sub-layouts.  We take care to respect the min/max sizes,
	and so, we now get this result:

	  (gdb) tui enable
	  (gdb) layout regs
	  (gdb) info win
	  Name       Lines Columns Focus
	  regs           8      80
	  src            8      80 (has focus)
	  status         1      80
	  cmd            8      80

	This looks more natural to me.

	This is obviously a change in behaviour, and so, lots of the existing
	tests need to be updated to take this into account.  None of the
	changes are huge, it's just a line or two (or column for width) moved
	between windows.

	gdb/tui: avoid fp exception when applying layouts
	Consider:

	  (gdb) tui enable
	  (gdb) layout src
	  (gdb) tui new-layout conly cmd 1
	  (gdb) layout conly

	After this, with current master, gdb crashes with a floating-point
	exception.

	The problem is that in tui_layout_split::apply, when we switch from
	'src' to 'conly', we will try to retain the cmd window height.  As
	such, the cmd window will become a fixed size window, which decreases
	the available_size, but doesn't count towards the total_weight.

	As the cmd window is the only window, the total_weight stays at zero,
	and, when we move into step 2, where we attempt to size the windows,
	we perform a divide by zero, and crash.

	After this commit we avoid the divide by zero, and just directly set
	the window size based on the fixed size.

	There is still a problem after this commit, when the conly layout is
	selected the cmd window retains its original height, which will only
	be part of the terminal.  The rest of the terminal is left unused.
	This issue will be addressed in a later commit, this commit is just
	about the floating-point exception.

	gdb/tui: add left_boxed_p and right_boxed_p member functions
	When I initially saw this code in tui_layout_split::apply, I assumed
	that this must be a bug:

	    /* Two adjacent boxed windows will share a border, making a bit
	       more size available.  */
	    if (i > 0
	        && m_splits[i - 1].layout->bottom_boxed_p ()
	        && m_splits[i].layout->top_boxed_p ())
	      ...

	After all, the apply might be laying out a horizontal layout, right?
	So checking bottom_boxed_p and top_boxed_p is clearly wrong.

	Well, it turns on, that due to the implementations of these things,
	bottom_boxed_p is equivalent to an imagined right_boxed_p, and
	top_boxed_p is equivalent to an imagined left_boxed_p.

	In this commit I've renamed both top_boxed_p and bottom_boxed_p to
	first_edge_has_border_p and last_edge_has_border_p respectively, and
	extended the comments in tui_layout_base to mention that these methods
	handle both horizontal and vertical layouts.

	Now, hopefully, the code shouldn't look like it only applies for
	vertical layouts.

	There should be no user visible changes after this commit.

	gdb/tui: add a tui debugging flag
	This commit adds 'set debug tui on|off' and 'show debug tui'.  This
	commit adds the control variable, and the printing macros in
	tui/tui.h.  I've then added some uses of these in tui.c and
	tui-layout.c.

	To help produce more useful debug output in tui-layout.c, I've added
	some helper member functions in the class tui_layout_split, and also
	moved the size_info struct out of tui_layout_split::apply into the
	tui_layout_split class.

	If tui debug is not turned on, then there should be no user visible
	changes after this commit.

	One thing to note is that, due to the way that the tui terminal is
	often cleared, the only way I've found this useful is when I do:

	  (gdb) tui enable
	  (gdb) set logging file /path/to/file
	  (gdb) set logging debugredirect on
	  (gdb) set logging enable on

	Additionally, gdb has some quirks when it comes to setting up logging
	redirect and switching interpreters.  Thus, the above only really
	works if the logging is enabled after the tui is enabled, and disabled
	again before the tui is disabled.

	Enabling logging and switching interpreters can cause undefined
	results, including crashes.  This is an existing bug in gdb[1], and
	has nothing directly to do with tui debug, but it is worth mentioning
	here I think.

2022-04-03  Andrew Burgess  <aburgess@redhat.com>

	gdb/tui: add new 'tui window width' command and 'winwidth' alias
	This commit adds a new command 'tui window width', and an alias
	'winwidth'.  This command is equivalent to the old 'winheight'
	command (which was recently renamed 'tui window height').

	Even though I recently moved the old tui commands under the tui
	namespace, and I would strongly encourage all new tui commands to be
	added as 'tui ....' only (users can create their own top-level aliases
	if they want), I'm breaking that suggestion here, and adding a
	'winwidth' alias.

	Given that we already have 'winheight' and have done for years, it
	just didn't seem right to no have the matching 'winwidth'.

	You might notice in the test that the window resizing doesn't quite
	work right.  I setup a horizontal layout, then grow and shrink the
	windows.  At the end of the test the windows should be back to their
	original size...

	... they are not.  This isn't my fault, honest!  GDB's window resizing
	is a little ... temperamental, and is prone to getting things slightly
	wrong during resizes, off by 1 type things.  This is true for height
	resizing, as well as the new width resizing.

	Later patches in this series will rework the resizing algorithm, which
	should improve things in this area.  For now, I'm happy that the width
	resizing is as good as the height resizing, given the existing quirks.

	For the docs side I include a paragraph that explains how multiple
	windows are required before the width can be adjusted.  For
	completeness, I've added the same paragraph to the winheight
	description.  With the predefined layouts this extra paragraph is not
	really needed for winheight, as there are always multiple windows on
	the screen.  However, with custom layouts, this might not be true, so
	adding the paragraph seems like a good idea.

	As for the changes in gdb itself, I've mostly just taken the existing
	height adjustment code, changed the name to make it generic 'size'
	adjustment, and added a boolean flag to indicate if we are adjusting
	the width or the height.

	gdb/tui: rename tui_layout_split:set_weights_from_heights
	In a following commit I'm going to add the ability to change the width
	of a tui window (when in a horizontal layout).  As a result, some of
	the places where we currently hard-code references to height need to
	be changed to handle either height, or width, based on whether we are
	in a vertical, or horizontal layout.

	This commit renames set_weights_from_heights to
	set_weights_from_sizes, and makes the function use either the height,
	or width as appropriate.

	Currently, the only place that we call this function is from the
	tui_layout_split::set_height function, in a part of the code we will
	only reach for vertical layouts, so the new code is not actually being
	used, but, this small change will help make later patches smaller, so
	I'm proposing this as a stand alone change.

	There should be no user visible changes after this commit.

	gdb: move some commands into the tui namespace
	There are a lot of tui related commands that live in the top-level
	command name space, e.g. layout, focus, refresh, winheight.

	Having them at the top level means less typing for the user, which is
	good, but, I think, makes command discovery harder.

	In this commit, I propose moving all of the above mentioned commands
	into the tui namespace, so 'layout' becomes 'tui layout', etc.  But I
	will then add aliases so that the old commands will still work,
	e.g. I'll make 'layout' an alias for 'tui layout'.

	The benefit I see in this work is that tui related commands can be
	more easily discovered by typing 'tui ' and then tab-completing.  Also
	the "official" command is now a tui-sub-command, this is visible in,
	for example, the help output, e.g.:

	  (gdb) help layout
	  tui layout, layout
	  Change the layout of windows.
	  Usage: tui layout prev | next | LAYOUT-NAME

	  List of tui layout subcommands:

	  tui layout asm -- Apply the "asm" layout.
	  tui layout next -- Apply the next TUI layout.
	  tui layout prev -- Apply the previous TUI layout.
	  tui layout regs -- Apply the TUI register layout.
	  tui layout split -- Apply the "split" layout.
	  tui layout src -- Apply the "src" layout.

	Which I think is a good thing, it makes it clearer that this is a tui
	command.

	I've added a NEWS entry and updated the docs to mention the new and
	old command names, with the new name being mentioned first.

	gdb/ctf: pass partial symtab's filename to buildsym_compunit
	I noticed that the CTF symbol reader passes the objfile's name to all
	buildsym_compunit instances it creates.  The result is that all
	compunit_symtabs created have the same name, that of the objfile:

	    { objfile /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0 ((struct objfile *) 0x613000005d00)
	      { ((struct compunit_symtab *) 0x621000286760)
	        debugformat ctf
	        producer (null)
	        name libbabeltrace2.so.0.0.0
	        dirname (null)
	        blockvector ((struct blockvector *) 0x6210003911d0)
	        user ((struct compunit_symtab *) (null))
	            { symtab /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0 ((struct symtab *) 0x6210003911f0)
	              fullname (null)
	              linetable ((struct linetable *) 0x0)
	            }
	      }
	      { ((struct compunit_symtab *) 0x621000275c10)
	        debugformat ctf
	        producer (null)
	        name libbabeltrace2.so.0.0.0
	        dirname (null)
	        blockvector ((struct blockvector *) 0x621000286710)
	        user ((struct compunit_symtab *) (null))
	            { symtab /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0 ((struct symtab *) 0x621000286730)
	              fullname (null)
	              linetable ((struct linetable *) 0x0)
	            }
	      }

	Notice the two "name libbabeltrace2.so.0.0.0".

	Change it to pass the partial_symtab's filename instead.  The output
	becomes:

	    { objfile /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0 ((struct objfile *) 0x613000005d00)
	      { ((struct compunit_symtab *) 0x621000295610)
	        debugformat ctf
	        producer (null)
	        name libbabeltrace2.so.0.0.0
	        dirname (null)
	        blockvector ((struct blockvector *) 0x6210003a15d0)
	        user ((struct compunit_symtab *) (null))
	            { symtab /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0 ((struct symtab *) 0x6210003a15f0)
	              fullname (null)
	              linetable ((struct linetable *) 0x0)
	            }
	      }
	      { ((struct compunit_symtab *) 0x621000288700)
	        debugformat ctf
	        producer (null)
	        name current-thread.c
	        dirname (null)
	        blockvector ((struct blockvector *) 0x6210002955c0)
	        user ((struct compunit_symtab *) (null))
	            { symtab /home/simark/src/babeltrace/src/lib/current-thread.c ((struct symtab *) 0x6210002955e0)
	              fullname (null)
	              linetable ((struct linetable *) 0x0)
	            }
	      }

	Note that the first compunit_symtab still has libbabeltrace2.so.0.0.0 as
	its name.  This is because the CTF symbol reader really creates a
	partial symtab named like this.  It appears to be because the debug info
	contains information that has been factored out of all CUs and is at the
	"top-level" of the objfile, outside any real CU.  So it creates a
	partial symtab and an artificial CU that's named after the objfile.

	gdb: print compunit_symtab name in "maint info symtabs"
	I think it would make sense to print a compunit_symtab's name in "maint
	info symtabs".  If you are looking for a given CU in the list, that's
	probably the field you will be looking at.  As the doc of
	compunit_symtab::name says, it is not meant to be a reliable file name,
	it is for debugging purposes (and "maint info symtabs" exists for
	debugging purposes).

	Sample output with the new field:

	gdb/ctf: don't create a buildsym_compunit when building partial symbols
	I am trying to do some changes to buildsym_compunit, so I am auditing
	the current uses.  Something seems odd with this use of
	buildsym_compunit (that this patch removes).

	A buildsym_compunit is normally used when building a compunit_symtab.
	That is, when expanding a partial symtab into a full compunit symtab.
	In ctfread.c, a buildsym_compunit is created in ctf_start_archive, which
	is only used when creating partial symtabs.  At this moment, I don't
	see how that's useful.  ctf_start_archive creates a new
	buildsym_compunit and starts a subfile.  But that buildsym_compunit is
	never used again.  It's just overriden in ctf_start_symtab, which means
	we leak the old buildsym_compunit, I suppose.

	Remove ctf_start_archive completely.  Add an assert in
	ctf_start_symtab to verify that we are not overwriting an existing
	buildsym_compunit (meaning we'd leak the existing one).  This assert
	triggers without the other part of the fix.  When doing:

	  $ ./gdb --data-directory=data-directory /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0
	  ...
	  (gdb) maintenance expand-symtabs
	  /home/simark/src/binutils-gdb/gdb/ctfread.c:1255: internal-error: ctf_start_symtab: Assertion `!ccp->builder' failed.

	Style URLs in GDB output
	I noticed that GDB will display URLs in a few spots.  This changes
	them to be styled.  Originally I thought I'd introduce a new "url"
	style, but there aren't many places to use this, so I just reused
	filename styling instead.  This patch also changes the debuginfod URL
	list to be printed one URL per line.  I think this is probably a bit
	easier to read.

	gdb: initialize ctf_context::builder in create_partial_symtab
	I built a random project with -gctf, in order to test the CTF support in
	GDB.  With my ASan/UBSan/etc-enabled build of GDB, I get:

	    $ ./gdb --data-directory=data-directory /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0
	    ...
	    Reading symbols from /tmp/babeltrace-ctf/src/lib/.libs/libbabeltrace2.so.0.0.0...
	    /home/simark/src/binutils-gdb/gdb/ctfread.c:1545:31: runtime error: member call on misaligned address 0xbebebebebebebebe for type 'struct buildsym_compunit', which requires 8 byte alignment
	    0xbebebebebebebebe: note: pointer points here

	The 0xbebebebebebebebe value is a sign that the ctf_context::builder
	field is uninitialized.  The problem probably goes under the radar if
	the field happens to be zero-initialized, because ctf_start_archive
	contains this code:

	  if (ccx->builder == nullptr)
	    {
	      ccx->builder = new buildsym_compunit (of,
			      of->original_name, nullptr, language_c, 0);

	If the field was zero-initialized (by chance), this will create a new
	buildsym_compunit.  But if the field was purposely filled with random
	bytes by one of the sanitizers, we won't create a buildsym_compunit here
	and we'll continue with ccx->builder equal to 0xbebebebebebebebe.

	Fix this the easy way by initializing ccx->builder where the other
	ctf_context fields are initialized (yeah, this code could be made nicer
	C++, but I am going for the obvious fix here).

	With this patch, this passes cleanly on my system:

	  $ make check TESTS="gdb.ctf/*.exp" RUNTESTFLAGS="CC_FOR_TARGET=/opt/gcc/git/bin/gcc"
	  # of expected passes            40

	... where /opt/gcc/git/bin/gcc is a gcc with CTF support, given my
	system gcc does not have it.

	gdb/linux-nat: remove check based on current_inferior in linux_handle_extended_wait
	The check removed by this patch, using current_inferior, looks wrong.
	When debugging multiple inferiors with the Linux native target and
	linux_handle_extended_wait is called, there's no guarantee about which
	is the current inferior.  The vfork-done event we receive could be for
	any inferior.  If the vfork-done event is for a non-current inferior, we
	end up wrongfully ignoring it.  As a result, the core never processes a
	TARGET_WAITKIND_VFORK_DONE event, program_space::breakpoints_not_allowed
	is never cleared, and breakpoints are never reinserted.  However,
	because the Linux native target decided to ignore the event, it resumed
	the thread - while breakpoints out.  And that's bad.

	The proposed fix is to remove this check.  Always report vfork-done
	events and let infrun's logic decide if it should be ignored.  We don't
	save much cycles by filtering the event here.

	Add a test that replicates the situation described above.  See comments
	in the test for more details.

	gdbserver/linux: set lwp !stopped when failing to resume
	I see some failures, at least in gdb.multi/multi-re-run.exp and
	gdb.threads/interrupted-hand-call.exp.  Running `stress -C $(nproc)` at
	the same time as the test makes those tests relatively frequent.

	Let's take gdb.multi/multi-re-run.exp as an example.  The failure looks
	like this, an unexpected "no resumed":

	    continue
	    Continuing.
	    No unwaited-for children left.
	    (gdb) FAIL: gdb.multi/multi-re-run.exp: re_run_inf=2: iter=1: continue until exit

	The situation is:

	 - Inferior 1 is stopped somewhere, it won't really play a role here.
	 - Inferior 2 has 2 threads, both stopped.
	 - We resume inferior 2, the leader thread is expected to exit, making
	   the process exit.

	From GDB's perspective, a failing run looks like this:

	What happens is:

	 - We resume the leader (713935) successfully.
	 - The leader exits.
	 - We resume the secondary thread (713936), we get ESRCH.  This is
	   expected this the leader has exited.
	 - resume_one_lwp_throw throws, it's caught by resume_one_lwp.
	 - resume_one_lwp checks with check_ptrace_stopped_lwp_gone that the
	   failure can be explained by the LWP becoming zombie, and swallows the
	   error.
	 - Note that this means that the secondary lwp still has stopped==1.
	 - wait_1 is called, probably because linux_process_target::resume marks
	   the async pipe at the end.
	 - The exit event isn't ready yet, probably because the machine is under
	   load, so waitpid returns nothing.
	 - check_zombie_leaders detects that the leader is zombie and deletes
	 - We try to find a resumed (non-stopped) LWP to get an event from,
	   there's none since the leader (that was resumed) is now deleted, and
	   the secondary thread is still marked stopped.
	   wait_for_event_filtered returns -1, causing wait_1 to return
	   NO_RESUMED.

	What I notice here is that there is some kind of race between the
	availability of the process' exit notification and the call to wait_1
	that results from marking the async pipe at the end of resume.

	I think what we want from this wait_1 invocation is to keep waiting, as
	we will eventually get thread exit notifications for both of our
	threads.

	The fix I came up with is to mark the secondary thread as !stopped (or
	resumed) when we fail to resume it.  This makes wait_1 see that there is
	at least one resume lwp, so it won't return NO_RESUMED.  I think this
	makes sense to consider it resumed, because we are going to receive an
	exit event for it.  Here's the GDBserver logs with the fix applied:

	gdb/testsuite/tui: implement _csi_P proc
	Since commit 3cd522938792 ("Change the pager to a ui_file"), I see these

	gdb/testsuite: add tests for Term
	While trying to review Andrew's patch here [1], I thought I spotted a
	bug in the handling of a CSI, but I had no way to know for sure.  So I
	thought it would be useful to have unit tests for the handling of
	control characters and control sequences of our toy terminal
	implementation.  It might help avoid chasing bugs in the GDB TUI when in
	reality it's a problem with the testsuite's terminal implementation.

	Add the gdb.tui/tuiterm.exp file to do that.  All currently supported
	control sequences and characters are tested, except _csi_m (the one that
	handles colors and stuff).  _csi_m should probably be tested too, but it
	will require more work.

	Fix a few issues that the tests spotted:

	 - backspace: according to [3] (table 4-1), a backspace when the cursor
	   is at the beginning of a line should have no effect.  Our
	   implementation did wrap to the end of the previous line.  Change our
	   implementation to match the doc (and the test).
	 - insert character: this control sequence is supposed to insert blank
	   characters, shifting all the rest of the line right.  The current
	   implementation moves N characters right, but it overwrites the
	   characters on the right instead of shifting them.  It also doesn't
	   insert blank characters at the cursor.
	 - Cursor down, forward, next line: off-by-one error when reaching the
	   end of the display.
	 - erase in display, line: off-by-one errors.
	 - vertical line position absolute: allowed setting the cursor outside
	   the display, when it should clamp it to the display size.

	I found that this web page [2] gave some good clues on the expected
	behavior of some control characters or sequences that some other pages
	didn't.

	Only allow QUIT on the main thread
	Pedro pointed out that gdb worker threads should not react to quits.
	While I don't think that the new DWARF reader can call QUIT from a
	worker thread (and I don't think the existing minsym threading code
	can either), it seems safest to address this before checking in the
	new code.  This patch arranges for the QUIT macro to only work on the
	main thread.

	Use gdb_printf and gdb_vprintf in more places
	Luis pointed out that I missed a spot in the gdb_printf conversion --
	namely aarch64-nat.c.  While looking at this, I found another spot in
	darwin-nat.c that I also missed.  I can't build either of these, but I
	think this patch should fix the problems.

	Consolidate definition of current_directory
	I noticed that both gdbserver and gdb define current_directory.
	However, as it is referenced by gdbsupport, it seemed better to define
	it there as well.  This patch also moves the declaration to
	pathstuff.h.  Tested by rebuilding.

	Decode "dynamic" interface types in Ada
	In Ada, if a class implements an interface and has a dynamic

	turn a pointer to the interface into a pointer to the whole object --
	is stored in the object itself.  This patch changes GDB to understand
	this.

	Because this only touches Ada code, and because Joel already reviewed
	it internally, I am checking it in.

	Remove unnecessary calls to wrap_here and gdb_flush
	Various spots in gdb currently know about the wrap buffer, and so are
	careful to call wrap_here to be certain that all output has been
	flushed.

	Now that the pager is just an ordinary stream, this isn't needed, and
	a simple call to gdb_flush is enough.

	Similarly, there are places where gdb prints to gdb_stderr, but first
	flushes gdb_stdout.  stderr_file already flushes gdb_stdout, so these
	aren't needed.

2022-03-29  Tom Tromey  <tom@tromey.com>

	Minor comment updates in utils.h
	This patch updates some comments in utils.h to more closely reflect
	the new reality.

	Remove vfprintf_styled
	Nothing calls vfprintf_styled any more, so remove it.

	Remove ui_out_flag::unfiltered_output
	There is no longer any need for ui_out_flag::unfiltered_output --
	nothing ever sets this flag.  This used to be needed to make the
	_unfiltered output work, but now only printf_unfiltered can be used,
	and it uses the puts_unfiltered method.  This patch removes the flag
	and the dead code.

	Rename fprintf_symbol_filtered
	fprintf_symbol_filtered is misnamed, because whether filtering happens
	is now up to the stream.  This renames it to fprintf_symbol, which
	isn't a great name (the first "f" doesn't mean much and the second one
	is truly meaningless here), but "print_symbol" was already taken.

	Rename puts_filtered_tabular
	puts_filtered_tabular is now misnamed, because whether filtering
	happens is now up to the stream.  So, rename it.  (This function is
	pretty weird, and should probably be rewritten to avoid using the
	chars_printed global, and moved into objc-lang.c.  However, I haven't
	done so.)

	Rename print_spaces_filtered
	print_spaces_filtered is now misnamed, because whether filtering
	happens is up to the stream.  So, rename it.

	Unify gdb printf functions
	Now that filtered and unfiltered output can be treated identically, we
	can unify the printf family of functions.  This is done under the name
	"gdb_printf".  Most of this patch was written by script.

	Unify gdb putc functions
	Now that filtered and unfiltered output can be treated identically, we
	can unify the putc family of functions.  This is done under the name
	"gdb_putc".  Most of this patch was written by script.

	Unify gdb puts functions
	Now that filtered and unfiltered output can be treated identically, we
	can unify the puts family of functions.  This is done under the name
	"gdb_puts".  Most of this patch was written by script.

	Unify vprintf functions
	Now that filtered and unfiltered output can be treated identically, we
	can unify the vprintf family of functions: vprintf_filtered,
	vprintf_unfiltered, vfprintf_filtered and vfprintf_unfiltered.  (For
	the gdb_stdout variants, recall that only printf_unfiltered gets truly
	unfiltered output at this point.)  This removes one such function and
	renames the remaining two to "gdb_vprintf".  All callers are updated.
	Much of this patch was written by script.

	Remove fputs_styled_unfiltered
	fputs_styled_unfiltered is only called from cli_ui_out, so remove it.
	This area will be further simplified in future patches.

	Change the pager to a ui_file
	This rewrites the output pager as a ui_file implementation.

	A new header is introduced to declare the pager class.  The
	implementation remains in utils.c for the time being, because there
	are some static globals there that must be used by this code.  (This
	could be cleaned up at some future date.)

	I went through all the text output in gdb to ensure that this change
	should be ok.  There are a few cases:

	* Any existing call to printf_unfiltered is required to be avoid the
	  pager.  This is ensured directly in the implementation.

	* All remaining calls to the f*_unfiltered functions -- the ones that
	  take an explicit ui_file -- either send to an unfiltered stream
	  (e.g., gdb_stderr), which is obviously ok; or conditionally send to
	  gdb_stdout

	  I investigated all such calls by searching for:

	    grep -e '\bf[a-z0-9_]*_unfiltered' *.[chyl] */*.[ch] | grep -v gdb_stdlog | grep -v gdb_stderr

	  This yields a number of candidates to check.

	  * The breakpoint _print_recreate family, and
	    save_trace_state_variables.  These are used for "save" commands
	    and so are fine.

	  * Things printing to a temporary stream.  Obviously ok.

	  * Disassembly selftests.

	  * print_gdb_help - this is non-obvious, but ok because paging isn't
	    yet enabled at this point during startup.

	  * serial.c - doens't use gdb_stdout

	  * The code in compile/.  This is all printing to a file.

	  * DWARF DIE dumping - doesn't reference gdb_stdout.

	* Calls to the _filtered form -- these are all clearly ok, because if
	  they are using gdb_stdout, then filtering will still apply; and if
	  not, then filtering never applied and still will not.

	Therefore, at this point, there is no longer any distinction between
	all the other _filtered and _unfiltered calls, and they can be
	unified.

	In this patch, take special note of the vfprintf_maybe_filtered and
	ui_file::vprintf change.  This is one instance of the above idea,
	erasing the distinction between filtered and unfiltered -- in this
	part of the change, the "unfiltered_output" flag is never passe to
	cli_ui_out.  Subsequent patches will go much further in this
	direction.

	Also note the can_emit_style_escape changes in ui-file.c.  Checking
	against gdb_stdout or gdb_stderr was always a bit of a hack; and now
	it is no longer needed, because this is decision can be more fully
	delegated to the particular ui_file implementation.

	ui_file::can_page is removed, because this patch removed the only call
	to it.

	I think this is the main part of fixing PR cli/7234.

	Remove vfprintf_styled_no_gdbfmt
	This removes vfprintf_styled_no_gdbfmt, inlining it at the sole point
	of call.

	Add style-escape methods to ui_file
	This adds emit_style_escape and reset_style methods to ui_file.  These
	aren't used yet, but they will be once the pager is converted to be a
	ui_file subclass.

	Add puts_unfiltered method to ui_file
	When the pager is rewritten as a ui_file, gdb will still need a way to
	bypass the filtering.  After examining a few approaches, I chose this
	patch, which adds a puts_unfiltered method to ui_file.  For most
	implementations of ui_file, this will just delegate to puts.  This
	patch also switches printf_unfiltered to use the new method.

	Only have one API for unfiltered output
	At the end of this series, the use of unfiltered output will be very
	restricted -- only places that definitely need it will use it.  To
	this end, I thought it would be good to reduce the number of
	_unfiltered APIs that are exposed.  This patch changes gdb so that
	only printf_unfiltered exists.  (After this patch, the f* variants
	still exist as well, but those will be removed later.)

2022-03-29  Tom Tromey  <tom@tromey.com>

	Remove some uses of printf_unfiltered
	A number of spots call printf_unfiltered only because they are in code
	that should not be interrupted by the pager.  However, I believe these
	cases are all handled by infrun's blanket ban on paging, and so can be
	converted to the default (_filtered) API.

	After this patch, I think all the remaining _unfiltered calls are ones
	that really ought to be.  A few -- namely in complete_command -- could
	be replaced by a scoped assignment to pagination_enabled, but for the
	remainder, the code seems simple enough like this.

2022-03-29  Tom Tromey  <tom@tromey.com>

	Use unfiltered output in annotate.c
	It seems to me that annotations should not be filtered.  While it
	might be weird for an annotation-based UI to use the pager, it's not,
	I think, out of the question.  This patch makes this change.

	gdb/remote: use current_inferior in read_ptid if multi-process not supported
	When parsing the ptid out of a reply package, if the multi-process
	extensions are not supported, use current_inferior's pid as the pid of
	the reported thread, instead of inferior_ptid.  This is needed because
	the inferior_ptid may be null_ptid although a legit context exists,
	due to a prior context switch via switch_to_inferior_no_thread.

	Below is a scenario that illustrates what could go wrong.  First,
	setup a multi-target scenario.  This is needed, because in a
	multi-target setting, the inferior_ptid is cleared out before waiting
	on targets.  The second inferior below sits on top of a remote target.
	Multi-process packets are disabled.

	GDB tried to stop Thread 42000.26253.0, which does not exist, and we
	are waiting for a stop event that will never happen.  The PID in
	'42000.26253.0', namely 42000, is the PID of magic_null_ptid.
	It comes from gdb/remote.c:read_ptid:

	  /* Since the stub is not sending a process id, then default to
	     what's in inferior_ptid, unless it's null at this point.  If so,
	     then since there's no way to know the pid of the reported
	     threads, use the magic number.  */
	  if (inferior_ptid == null_ptid)
	    pid = magic_null_ptid.pid ();
	  else
	    pid = inferior_ptid.pid ();

	  if (obuf)
	    *obuf = pp;
	  return ptid_t (pid, tid);

	Because multi-process was turned off, GDB did not parse an explicitly
	specified PID.  Furthermore, inferior_ptid == null_ptid, and
	eventually GDB picked the PID from magic_null_ptid.

	If target-non-stop is not turned on at the beginning, the same bug
	reveals itself as a duplicated thread as shown below.

	gdb/testsuite: fix test failure when building against readline v7
	The test added in the commit:

	  commit a6b413d24ccc5d76179bab866834e11fd6fec294
	  Date:   Fri Mar 11 14:44:03 2022 +0000

	      gdb: work around prompt corruption caused by bracketed-paste-mode

	Was not written with readline 7 in mind, only readline 8+.  Between
	readline 7 and 8 the escape sequence used to disable bracketed paste
	mode changed, an additional '\r' character was added to the end.  In
	fact, it was the addition of this '\r' character that triggered the
	issue for which the above commit is part of the solution.

	Anyway, the test tries to spot the case where the output from GDB is
	not perfect, but does have the above work around applied.  However,
	the pattern in the test assumes that the problematic '\r' will be
	present, and this is only true for readline 8+.  With readline 7 the
	test was failing.

	In this commit I generalise the pattern a little so that the test will
	still KFAIL with readline 7.

	It's a little unfortunate that the test is KFAILing with readline 7,
	as without the problematic '\r' there's actually no reason that GDB
	couldn't "do the right thing" in this case, in which case, the test
	would PASS, but that would require changes within GDB itself.

	My preference then is that initially we patch the test to get it
	KFAILing, then in a separate commit I can modify GDB so that it can
	PASS with readline 7.

	gdb/testsuite: fix copy & paste error in gdb.python/py-format-address.exp
	The test gdb.python/py-format-address.exp, added in commit:

	  commit 25209e2c6979c3838e14e099f0333609810db280
	  Date:   Sat Oct 23 09:59:25 2021 +0100

	      gdb/python: add gdb.format_address function

	included 3 copy & paste errors where the wrong address was used in the
	expected output patterns.

	The test compiles two almost identical test binaries (one function
	changes its name, that's the only difference), two inferiors are
	created, each inferior using one of the test binaries.

	We then take the address of the name changing function in both
	inferiors ('foo' in inferior 1 and 'bar' in inferior 2) and the tests
	are carried out using these addresses.

	What we're checking for is that symbols 'foo' and 'bar' show up in the
	correct inferior, and that (as this test is for a Python API feature),
	the user can have one inferior selected, but ask about the other
	inferior, and see the correct symbol in the result.

	The hope is that the two binaries will be laid out identically by the
	compiler, and that 'foo' and 'bar' will be at the same address.  This
	is fine, unless the executable is compiled as PIE (position
	independent executable), in which case there is a problem.

	The problem is that though inferior 1 is set running, the inferior 2
	never is.  If the executables are compiled as PIE, then the address in
	the inferior 2 will not have been resolved, while the address in the
	inferior 1 will have been, and so the two addresses we use in the
	tests will be different.

	This issue was reported here:

	  https://sourceware.org/pipermail/gdb-patches/2022-March/186911.html

	The first part of the fix is to use the correct address variable in
	the expected output patterns, with this change the tests pass even
	when the executables are compiled as PIE.

	A second part of this fix is to pass the 'nopie' option when we
	compile the tests, this should ensure that the address obtained in
	inferior 2 is the same as the address from inferior 1, which makes the
	test more useful.

	gdb/mi: fix use after free of frame_info causing spurious notifications
	In commit:

	  commit a2757c4ed693cef4ecc4dcdcb2518353eb6b3c3f
	  Date:   Wed Mar 16 15:08:22 2022 +0000

	      gdb/mi: consistently notify user when GDB/MI client uses -thread-select

	Changes were made to GDB to address some inconsistencies in when
	notifications are sent from a MI terminal to a CLI terminal (when
	multiple terminals are in use, see new-ui command).

	Unfortunately, in order to track when the currently selected frame has
	changed, that commit grabs a frame_info pointer before and after an MI
	command has executed, and compares the pointers to see if the frame
	has changed.

	This is not safe.

	If the frame cache is deleted for any reason then the frame_info
	pointer captured before the command started, is no longer valid, and
	any comparisons based on that pointer are undefined.

	This was leading to random test failures for some folk, see:

	  https://sourceware.org/pipermail/gdb-patches/2022-March/186867.html

	This commit changes GDB so we no longer hold frame_info pointers, but
	instead store the frame_id and frame_level, this is safe even when the
	frame cache is flushed.

	bfd/Dwarf2: gas doesn't mangle names
	Include the language identifier emitted by gas in the set of ones where
	no mangled names are expected. Even if there could be "hand-mangled"
	names, gas doesn't emit DW_AT_linkage_name in the first place.

	bfd/Dwarf2: make find-nearest-line returned function name consistent
	Prior to entering the enclosing "else if()" the earlier associated if()
	checks function->is_linkage and, if set, uses function->name. The
	comment in patch context precedes (and explains) the setting
	function->is_linkage. Yet with the flag set, we should then also return
	the function name, just like said earlier if() would do when we came
	here a 2nd time for the same "addr". And indeed passing the same address
	twice on addr2line's command line would resolve the function for the 2nd
	instance, but not for the 1st (if this code path is taken). (This,
	obviously, is particularly relevant when there's no ELF symbol table in
	the first place, like would be the case - naturally - in PE/COFF
	binaries, for example.)

	gas/Dwarf: special-case .linefile only for macros
	Restrict the PR gas/16908 workaround to just macros, matching the
	original intention as well as the comment there. For constructs like
	.irp or .rept the reasoning doesn't apply, as there's no separate
	"invocation" point which may be of interest to record (for, as said
	there, short macros).

	RISC-V: correct FCVT.Q.L[U]
	While the spec isn't explicit about this, it pointing out the similarity
	with the D extension ought to extend to the ignoring of a meaningless
	rounding mode: "Note FCVT.D.W[U] always produces an exact result and is
	unaffected by rounding mode." Hence the chosen encodings also ought to
	match.

	Note that to avoid breaking existing code the forms with a 3rd operand
	are not removed, which means there continues to be a difference to
	FCVT.D.W[U].

	Add Rust parser check for end of expression
	I noticed that "print 5," passed in Rust -- the parser wasn't checking
	that the entire input was used.  This patch fixes the problem.  This
	in turn pointed out another bug in the parser, namely that it didn't
	lex the next token after handling a string token.  This is also fixed
	here.

	Switch gdb_stdlog to use timestamped_file
	Currently, timestamps for logging are done by looking for the use of
	gdb_stdlog in vfprintf_unfiltered.  This seems potentially buggy, in
	that during logging or other redirects (like execute_fn_to_ui_file) we
	might have gdb_stdout==gdb_stdlog and so, conceivably, wind up with
	timestamps in a log when they were not desired.

	It seems better, instead, for timestamps to be a property of the
	ui_file itself.

	This patch changes gdb to use the new timestamped_file for gdb_stdlog
	where appropriate, and removes the special case from
	vfprintf_unfiltered.

	Note that this may somewhat change the output in some cases -- in
	particular, when going through execute_fn_to_ui_file (or the _string
	variant), timestamps won't be emitted.  This could be fixed in those
	functions, but it wasn't clear to me whether this is really desirable.

	Note also that this changes the TUI to send gdb_stdlog to gdb_stderr.
	I imagine that the previous use of gdb_stdout here was inadvertent.
	(And in any case it probably doesn't matter.)

2022-03-28  Tom Tromey  <tom@tromey.com>

	Add new timestamped_file class
	This adds a "timestamped_file" subclass of ui_file.  This class adds a
	timestamp to its output when appropriate.  That is, it follows the
	rule already used in vfprintf_unfiltered of adding a timestamp at most

	Use unique_ptr in CLI logging code
	This changes the CLI logging code to avoid manual memory management
	(to the extent possible) by using unique_ptr in a couple of spots.
	This will come in handy in a later patch.

	Simplify the CLI set_logging logic
	The CLI's set_logging logic seemed unnecessarily complicated to me.
	This patch simplifies it, with an eye toward changing it to use RAII
	objects in a subsequent patch.

	I did not touch the corresponding MI code.  That code seems incorrect
	(nothing ever uses raw_stdlog, and nothing ever sets
	saved_raw_stdlog).  I didn't attempt to fix this, because I question
	whether this is even useful for MI.

	Handle multiple addresses in call_site_target
	A large customer program has a function that is partitioned into hot
	and cold parts.  A variable in a callee of this function is described
	using DW_OP_GNU_entry_value, but gdb gets confused when trying to find
	the caller.  I tracked this down to dwarf2_get_pc_bounds interpreting
	the function's changes so that the returned low PC is the "wrong"
	function.

	Intead, when processing DW_TAG_call_site, the low PC of each range in
	DW_AT_ranges should be preserved in the call_site_target.  This fixes
	the variable lookup in the test case I have.

	I didn't write a standalone test for this as it seemed excessively
	complicated.

2022-03-28  Tom Tromey  <tromey@adacore.com>

	Change call_site_target to iterate over addresses
	In order to handle the case where a call site target might refer to
	multiple addresses, we change the code to use a callback style.  Any
	spot using call_site_target::address now passes in a callback function
	that may be called multiple times.

2022-03-28  Tom Tromey  <tromey@adacore.com>

	Change call_site_find_chain_1 to work recursively
	call_site_find_chain_1 has a comment claiming that recursive calls
	would be too expensive.  However, I doubt this is so expensive; and
	furthermore the explicit state management approach here is difficult
	both to understand and to modify.  This patch changes this code to use
	explicit recursion, so that a subsequent patch can generalize this
	code without undue trauma.

	Additionally, I think this patch detects a latent bug in the recursion
	code.  (It's hard for me to be completely certain.)  The bug is that
	when a new target_call_site is entered, the code does:

		  if (target_call_site)
		    {
		      if (addr_hash.insert (target_call_site->pc ()).second)
			{
			  /* Successfully entered TARGET_CALL_SITE.  */

			  chain.push_back (target_call_site);
			  break;
			}
		    }

	Here, if entering the target_call_site fails, then any tail_call_next
	elements in this call site are not visited.  However, if this code
	does happen to enter a call site, then the tail_call_next elements
	will be visited during backtracking.  This applies when doing the
	backtracking as well -- it will only continue through a given chain as
	long as each element in the chain can successfully be visited.

	I'd appreciate some review of this.  If this behavior is intentional,
	it can be added to the new implementation.

2022-03-28  Tom Tromey  <tromey@adacore.com>

	Constify chain_candidate
	While investigating this bug, I wasn't sure if chain_candidate might
	update 'chain'.  I changed it to accept a const reference, making it
	clear that it cannot.  This simplifies the code a tiny bit as well.

	Make call_site_target members private
	This makes the data members of call_site_target 'private'.  This lets
	us remove most of its public API.  call_site_to_target_addr is changed
	to be a method of this type.  This is a preparatory refactoring for
	the fix at the end of this series.

	Change call_site_target to use custom type and enum
	call_site_target reuses field_loc_kind and field_location.  However,
	it has never used the full range of the field_loc_kind enum.  In a
	subsequent patch, I plan to add a new 'kind' here, so it seemed best
	to avoid this reuse and instead introduce new types here.

	libtool.m4: fix the NM="/nm/over/here -B/option/with/path" case
	My previous nm patch handled all cases but one -- if the user set NM in
	the environment to a path which contained an option, libtool's nm
	detection tries to run nm against a copy of nm with the options in it:
	e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
	test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
	This is unlikely to be desirable: in this case we should run
	"/usr/bin/nm --blargle /usr/bin/nm".

	Furthermore, as part of this nm has to detect when the passed-in $NM
	contains a path, and in that case avoid doing a path search itself.
	This too was thrown off if an option contained something that looked
	like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
	"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
	to see whether that nm exists, finds it doesn't, and wrongly concludes
	that nm -p or whatever does not work).

	Fix all of these by clipping all options (defined as everything
	including and after the first " -") before deciding whether nm
	contains a path (but not using the clipped value for anything else),
	and then removing all options from the path-modified nm before
	looking to see whether that nm existed.

	NM=my-nm now does a path search and runs e.g.
	  /usr/bin/my-nm -B /usr/bin/my-nm

	NM=/usr/bin/my-nm now avoids a path search and runs e.g.
	  /usr/bin/my-nm -B /usr/bin/my-nm

	NM="my-nm -p../wombat" now does a path search and runs e.g.
	  /usr/bin/my-nm -p../wombat -B /usr/bin/my-nm

	NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
	  ../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm

	This seems to be all combinations, including those used by GCC bootstrap
	(which, before this commit, fails to bootstrap when configured
	--with-build-config=bootstrap-lto, because the lto plugin is now using
	--export-symbols-regex, which requires libtool to find a working nm,
	while also using -B../prev-gcc to point at the lto plugin associated
	with the GCC just built.)

	Regenerate all affected configure scripts.

	Remove download size from debuginfod progress messages if unavailable
	Currently debuginfod progress update messages include the size of
	each download:

	This value originates from the Content-Length HTTP header of the

	      gdb/testsuite: relax pattern in new gdb.mi/mi-multi-commands.exp test

	The second of these commits was intended to address periodic test
	failures that I was seeing, and this change did fix some problems,
	but, unfortunately, introduced other issues.

	The problem is that the test relies on sending two commands to GDB in
	a single write.  As the characters that make these two commands arrive
	they are echoed to GDB's console.  However, there is a race between
	how quickly the characters are echoed and how quickly GDB decides to
	act on the incoming commands.

	Usually, both commands are echoed in full before GDB acts on the first
	command, but sometimes this is not the case, and GDB can execute the
	first command before both commands are fully echoed to the console.
	In this case, the output of the first command will be mixed in with
	the echoing of the second command.

	This mixing of the command echoing and the first command output is
	what was causing failures in the original version of the test.

	The second commit relaxed the expected output pattern a little, but
	was still susceptible to failures, so this commit further relaxes the
	pattern.

	Now, we look for the first command output with no regard to what is
	before, or after the command.  Then we look for the first mi prompt to
	indicate that the first command has completed.

	I believe that this change should make the test more stable than it
	was before.

	libctf: add LIBCTF_WRITE_FOREIGN_ENDIAN debugging option
	libctf has always handled endianness differences by detecting
	foreign-endian CTF dicts on the input and endian-flipping them: dicts
	are always written in native endianness.  This makes endian-awareness
	very low overhead, but it means that the foreign-endian code paths
	almost never get routinely tested, since "make check" usually reads in
	dicts ld has just written out: only a few corrupted-CTF tests are
	actually in fixed endianness, and even they only test the foreign-
	endian code paths when you run make check on a big-endian machine.
	(And the fix is surely not to add more .s-based tests like that, because
	they are a nightmare to maintain compared to the C-code-based ones.)

	To improve on this, add a new environment variable,
	LIBCTF_WRITE_FOREIGN_ENDIAN, which causes libctf to unconditionally
	endian-flip at ctf_write time, so the output is always in the wrong
	endianness.  This then tests the foreign-endian read paths properly
	at open time.

	Make this easier by restructuring the writeout code in ctf-serialize.c,
	which duplicates the maybe-gzip-and-write-out code three times (once
	for ctf_write_mem, with thresholding, and once each for
	ctf_compress_write and ctf_write just so those can avoid thresholding
	and/or compression).  Instead, have the latter two call the former
	with thresholds of 0 or (size_t) -1, respectively.

	The endian-flipping code itself gains a bit of complexity, because
	one single endian-flipper (flip_types) was assuming the input to be
	in foreign-endian form and assuming it could pull things out of the
	input once they had been flipped and make sense of them. At the
	cost of a few lines of duplicated initializations, teach it to
	read before flipping if we're flipping to foreign-endianness instead
	of away from it.

	libctf, ld: diagnose corrupted CTF header cth_strlen
	The last section in a CTF dict is the string table, at an offset
	represented by the cth_stroff header field.  Its length is recorded in
	the next field, cth_strlen, and the two added together are taken as the
	size of the CTF dict.  Upon opening a dict, we check that none of the
	header offsets exceed this size, and we check when uncompressing a
	compressed dict that the result of the uncompression is the same length:
	but CTF dicts need not be compressed, and short ones are not.
	Uncompressed dicts just use the ctf_size without checking it.  This
	field is thankfully almost unused: it is mostly used when reserializing
	a dict, which can't be done to dicts read off disk since they're
	read-only.

	However, when opening an uncompressed foreign-endian dict we have to
	copy it out of the mmaped region it is stored in so we can endian-
	swap it, and we use ctf_size when doing that.  When the cth_strlen is
	corrupt, this can overrun.

	Fix this by checking the ctf_size in all uncompressed cases, just as we
	already do in the compressed case.  Add a new test.

	This came to light because various corrupted-CTF raw-asm tests had an
	incorrect cth_strlen: fix all of them so they produce the expected
	error again.

	include, libctf, ld: extend variable section to contain functions too
	The CTF variable section is an optional (usually-not-present) section in
	the CTF dict which contains name -> type mappings corresponding to data
	symbols that are present in the linker input but not in the output
	symbol table: the idea is that programs that use their own symbol-
	resolution mechanisms can use this section to look up the types of
	symbols they have found using their own mechanism.

	Because these removed symbols (mostly static variables, functions, etc)
	all have names that are unlikely to appear in the ELF symtab and because
	very few programs have their own symbol-resolution mechanisms, a special
	linker flag (--ctf-variables) is needed to emit this section.

	Historically, we emitted only removed data symbols into the variable
	section.  This seemed to make sense at the time, but in hindsight it
	really doesn't: functions are symbols too, and a C program can look them
	up just like any other type.  So extend the variable section so that it
	contains all static function symbols too (if it is emitted at all), with
	types of kind CTF_K_FUNCTION.

	This is a little fiddly.  We relied on compiler assistance for data
	symbols: the compiler simply emits all data symbols twice, once into the
	symtypetab as an indexed symbol and once into the variable section.

	Rather than wait for a suitably adjusted compiler that does the same for
	function symbols, we can pluck unreported function symbols out of the
	symtab and add them to the variable section ourselves.  While we're at
	it, we do the same with data symbols: this is redundant right now
	because the compiler does it, but it costs very little time and lets the
	compiler drop this kludge and save a little space in .o files.

	ld, testsuite: improve CTF-availability test
	The test for -gctf support in the compiler is used to determine when to
	run the ld-ctf tests and most of those in libctf.  Unfortunately,
	because it uses check_compiler_available and compile_one_cc, it will
	fail whenever the compiler emits anything on stderr, even if it
	actually does support CTF perfectly well.

	So, instead, ask the compiler to emit assembler output and grep it for
	references to ".ctf": this is highly unlikely to be present if the
	compiler does not support CTF.  (This will need adjusting when CTF grows
	support for non-ELF platforms that don't dot-prepend their section
	names, but right now the linker doesn't link CTF on any such platforms
	in any case.)

	With this in place we can do things like run all the libctf tests under
	leak sanitizers etc even if those spray warnings on simple CTF
	compilations, rather than being blocked from doing so just when we would
	most like to.

	gdb/python: remove Python 2 support
	New in this version:

	 - Add a PY_MAJOR_VERSION check in configure.ac / AC_TRY_LIBPYTHON.  If
	   the user passes --with-python=python2, this will cause a configure
	   failure saying that GDB only supports Python 3.

	Support for Python 2 is a maintenance burden for any patches touching
	Python support.  Among others, the differences between Python 2 and 3
	string and integer types are subtle.  It requires a lot of effort and
	thinking to get something that behaves correctly on both.  And that's if
	the author and reviewer of the patch even remember to test with Python
	2.

	See this thread for an example:

	  https://sourceware.org/pipermail/gdb-patches/2021-December/184260.html

	So, remove Python 2 support.  Update the documentation to state that GDB
	can be built against Python 3 (as opposed to Python 2 or 3).

	Update all the spots that use:

	 - sys.version_info
	 - IS_PY3K
	 - PY_MAJOR_VERSION
	 - gdb_py_is_py3k

	... to only keep the Python 3 portions and drop the use of some
	now-removed compatibility macros.

	I did not update the configure script more than just removing the
	explicit references to Python 2.  We could maybe do more there, like
	check the Python version and reject it if that version is not
	supported.  Otherwise (with this patch), things will only fail at
	compile time, so it won't really be clear to the user that they are
	trying to use an unsupported Python version.  But I'm a bit lost in the
	configure code that checks for Python, so I kept that for later.

	x86: reject relocations involving registers
	To prevent fatal or even internal errors, add a simple check to

	reason).

	x86: improve resolution of register equates
	Allow transitive (or recursive) equates to work in addition to direct

	- the equate being straight of a register, i.e. no expressions involved

	- at the point of use there's no forward ref left which cannot be
	  resolved, yet.

	x86: don't attempt to resolve equates and alike from i386_parse_name()

	Perhaps right from its introduction in 4d1bb7955a8b it was wrong for
	i386_parse_name() to call parse_register(). This being a hook from the
	expression parser, it shouldn't be resolving e.g. equated symbols.
	That's relevant only for all other callers of parse_register().

	To compensate, in Intel syntax mode check_register() needs calling;
	perhaps not doing so was an oversight right when the function was
	introduced. This is necessary in particular to force EVEX encoding when
	VRex registers are used (but of course also to reject bad uses of
	registers, i.e. fully matching what parse_register() needs it for).

	gas/Dwarf5: re-use file 0 line string table entry when faking file 0
	No need to emit the same string a 2nd time for file 1 in this case.

	gas/Dwarf5: adjust .debug_line file 0 checking
	First of all when a table entry has a NULL filename, the two inner if()s
	are better done the other way around: The 2nd doesn't depend on what the
	first does. This then renders redundant half of the conditions of the
	other if() and clarifies that subsequently only entry 0 is dealt with
	(indicating that part of the comment was wrong). Finally for there to be
	a usable name in slot 1, files_in_use needs to be larger than 1 and slot
	1's (rather than slot 0's) name needs to be non-NULL.

	gas/Dwarf5: drop dead code
	Commit 3417bfca676f ("GAS: DWARF-5: Ensure that the 0'th entry in the
	directory table contains the current... ") added a "dwarf_level < 5"
	check to out_dir_and_file_list(). This rendered dead that branch of the
	construct, due to the enclosing if()'s "DWARF2_LINE_VERSION >= 5".
	Delete that code as well as the corresponding part of the comment.

	While there also drop a redundant "dirs != NULL": "dirs" will always be
	non-NULL when dirs_in_use is not zero.

	gas/Dwarf: improve debug info generation from .irp and alike blocks
	Tying the bumping of the logical line number to reading from the
	original source file looks wrong: Upon finishing of the processing of an
	sb the original values will be restored anyway. Yet without bumping the
	line counter uses of .line inside e.g. an .irp construct won't have the
	intended effect: Such uses may be necessary to ensure proper debug info
	is emitted in particular when switching sections inside the .irp body,
	as dwarf2_gen_line_info() would bail without doing anything when it
	finds the line number unchanged from what it saw last.

	ELF32: don't silently truncate relocation addends
	At least x86-64's x32 sub-mode and RISC-V's 32-bit mode calculate
	addends as 64-bit values, but store them in signed 32-bit fields when
	generating the file without encountering any earlier error. When the
	relocated field is a 64-bit one, the value resulting after processing
	the relocation record when linking (or the latest when loading) may
	thus be wrong due to the truncation.

	With the code change in place, one x32 testcase actually triggers the
	new diagnostic. That one case of too large a (negative) addend is being
	adjusted alongside the addition of a new testcase to actually trigger
	the new error. (Note that due to internal BFD behavior the relocation in
	.data doesn't get processed anymore after the errors in .text.)

	Note that in principle it is possible to express 64-bit relocations in
	ELF32, but this would require .rel relocations, i.e. with the addend
	stored in the 64-bit field being relocated. But I guess it would be a
	lot of effort for little gain to actually support this.

	gas: retain whitespace between strings
	Macro arguments may be separated by commas or just whitespace. Macro
	arguments may also be quoted (where one level of quotes is removed in
	the course of determining the values for the respective formal
	parameters). Furthermore this quote removal knows _two_ somewhat odd
	escaping mechanisms: One, apparently in existence forever, is that a
	pair of quotes counts as the escaping of a quote, with the pair being
	transformed to a single quote in the course of quote removal. The other
	(introduced by c06ae4f232e6) looks more usual on the surface in that it
	deals with \" sequences, but it _retains_ the escaping \. Hence only the
	former mechanism is suitable when the value to be used by the macro body
	is to contain a quote. Yet this results in ambiguity of what "a""b" is
	intended to mean; elsewhere (e.g. for .ascii) it represents two
	successive string literals. However, in any event is the above different
	from "a" "b": I don't think this can be viewed the same as "a""b" when
	processing macro arguments.

	Change the scrubber to retain such whitespace, by making the processing
	of strings more similar to that of symbols. And indeed this appears to
	make sense when taking into account that for quite a while gas has been
	supporting quoted symbol names.

	Taking a more general view, however, the change doesn't go quite far
	enough. There are further cases where significant whitespace is removed
	by the scrubber. The new testcase enumerates a few in its ".if 0"
	section. I'm afraid the only way that I see to deal with this would be
	to significantly simplify the scrubber, such that it wouldn't do much
	more than collapse sequences of unquoted whitespace into a single blank.
	To be honest problems in this area aren't really surprising when seeing
	that there's hardly any checking of .macro use throughout the testsuite
	(and in particular in the [relatively] generic tests under all/).

	Automatic date update in version.in

2022-03-22  John Baldwin  <jhb@FreeBSD.org>

	Add support for hardware breakpoints/watchpoints on FreeBSD/Aarch64.
	This shares aarch64-nat.c and nat/aarch64-hw-point.c with the Linux
	native target.  Since FreeBSD writes all of the debug registers in one
	ptrace op, use an unordered_set<> to track the "dirty" state for
	threads rather than bitmasks of modified registers.

	fbsd-nat: Add a low_prepare_to_resume virtual method.
	This method can be overridden by architecture-specific targets to
	perform additional work before a thread is resumed.

2022-03-22  John Baldwin  <jhb@FreeBSD.org>

	fbsd-nat: Add a low_delete_thread virtual method.
	This method can be overridden by architecture-specific targets to
	perform additional work when a thread is deleted.

	Note that this method is only invoked on systems supporting LWP
	events, but the pending use case (aarch64 debug registers) is not
	supported on older kernels that do not support LWP events.

2022-03-22  John Baldwin  <jhb@FreeBSD.org>

	fbsd-nat: Add helper routine to fetch siginfo_t for a ptid.

2022-03-22  John Baldwin  <jhb@FreeBSD.org>

	aarch64: Add an aarch64_nat_target mixin class.
	This class includes platform-independent target methods for hardware
	breakpoints and watchpoints using routines from
	nat/aarch64-hw-point.c.

	stopped_data_address is not platform-independent since the FAR
	register holding the address for a breakpoint hit must be fetched in a
	platform-specific manner.  However, aarch64_stopped_data_address is
	provided as a helper routine which performs platform-independent
	validation given the value of the FAR register.

	For tracking the per-process debug register mirror state, use an
	unordered_map indexed by pid as recently adopted in x86-nat.c rather
	than a manual linked-list.

2022-03-22  John Baldwin  <jhb@FreeBSD.org>

	nat: Split out platform-independent aarch64 debug register support.
	Move non-Linux-specific support for hardware break/watchpoints from
	nat/aarch64-linux-hw-point.c to nat/aarch64-hw-point.c.  Changes
	beyond a simple split of the code are:

	- aarch64_linux_region_ok_for_watchpoint and
	  aarch64_linux_any_set_debug_regs_state renamed to drop linux_ as
	  they are not platform specific.

	- Platforms must implement the aarch64_notify_debug_reg_change
	  function which is invoked from the platform-independent code when a
	  debug register changes for a given debug register state.  This does
	  not use the indirection of a 'low' structure as is done for x86.

	- The handling for kernel_supports_any_contiguous_range is not
	  pristine.  For non-Linux it is simply defined to true.  Some uses of
	  this could perhaps be implemented as new 'low' routines for the
	  various places that check it instead?

	- Pass down ptid into aarch64_handle_breakpoint and
	  aarch64_handle_watchpoint rather than using current_lwp_ptid which
	  is only defined on Linux.  In addition, pass the ptid on to
	  aarch64_notify_debug_reg_change instead of the unused state
	  argument.

2022-03-22  John Baldwin  <jhb@FreeBSD.org>

	x86-fbsd-nat: Copy debug register state on fork.
	Use the FreeBSD native target low_new_fork hook to copy the
	per-process debug state from the parent to the child on fork.

	fbsd-nat: Add a low_new_fork virtual method.
	This method can be overridden by architecture-specific targets to
	perform additional work when a new child process is forked.

2022-03-22  John Baldwin  <jhb@FreeBSD.org>

	Add an x86_fbsd_nat_target mixin class for FreeBSD x86 native targets.
	This class implements debug register support common between the i386
	and amd64 native targets.

	While here, remove #ifdef's for HAVE_PT_GETDBREGS in FreeBSD-specific
	code.  The ptrace request has been present on FreeBSD x86
	architectures since 4.0 (released in March 2000).  The last FreeBSD
	release without this support is 3.5 released in June 2000.

2022-03-22  John Baldwin  <jhb@FreeBSD.org>

	x86-nat: Add x86_lookup_debug_reg_state.
	This function returns nullptr if debug register state does not yet
	exist for a given process rather than creating new state.

	x86-nat: Use an unordered_map to store per-pid debug reg state.
	This replaces a manual linked list which used O(n) lookup and removal.

	Remove USE_SIGTRAP_SIGINFO condition for FreeBSD/x86 debug regs support.
	For BSD x86 targets, stopped_by_hw_breakpoint doesn't check siginfo_t
	but inspects the DR6 register directly via PT_GETDBREGS.

	gdb/python: add gdb.format_address function
	Add a new function, gdb.format_address, which is a wrapper around
	GDB's print_address function.

	This method takes an address, and returns a string with the format:

	  ADDRESS <SYMBOL+OFFSET>

	Where, ADDRESS is the original address, formatted as hexadecimal,
	SYMBOL is a symbol with an address lower than ADDRESS, and OFFSET is
	the offset from SYMBOL to ADDRESS in decimal.

	If there's no SYMBOL suitably close to ADDRESS then the
	<SYMBOL+OFFSET> part is not included.

	This is useful if a user wants to write a Python script that
	pretty-prints addresses, the user no longer needs to do manual symbol
	lookup, or worry about correctly formatting addresses.

	Additionally, there are some settings that effect how GDB picks
	SYMBOL, and whether the file name and line number should be included
	with the SYMBOL name, the gdb.format_address function ensures that the
	users Python script also benefits from these settings.

	The gdb.format_address by default selects SYMBOL from the current
	inferiors program space, and address is formatted using the
	architecture for the current inferior.  However, a user can also
	explicitly pass a program space and architecture like this:

	  gdb.format_address(ADDRESS, PROGRAM_SPACE, ARCHITECTURE)

	In order to format an address for a different inferior.

	Notes on the implementation:

	In py-arch.c I extended arch_object_to_gdbarch to add an assertion for
	the type of the PyObject being worked on.  Prior to this commit all
	uses of arch_object_to_gdbarch were guaranteed to pass this function a
	gdb.Architecture object, but, with this commit, this might not be the
	case.

	So, with this commit I've made it a requirement that the PyObject be a
	gdb.Architecture, and this is checked with the assert.  And in order
	that callers from other files can check if they have a
	gdb.Architecture object, I've added the new function
	gdbpy_is_architecture.

	In py-progspace.c I've added two new function, the first
	progspace_object_to_program_space, converts a PyObject of type
	gdb.Progspace to the associated program_space pointer, and
	gdbpy_is_progspace checks if a PyObject is a gdb.Progspace or not.

	Add debuginfod support to core_target::build_file_mappings and

	missing executables and shared libraries referenced in core files.

	Also add debuginfod support to solib_map_sections so that previously

	cache.

	When core file shared libraries are found locally, verify that their
	build-ids match the corresponding build-ids found in the core file.
	If there is a mismatch, attempt to query debuginfod for the correct
	build and print a warning if unsuccessful:

	  warning: Build-id of /lib64/libc.so.6 does not match core file.

	Also disable debuginfod when gcore invokes gdb.  Debuginfo is not

	Watchpoint followed by catchpoint misreports watchpoint (PR gdb/28621)
	If GDB reports a watchpoint hit, and then the next event is not
	TARGET_WAITKIND_STOPPED, but instead some event for which there's a
	catchpoint, such that GDB calls bpstat_stop_status, GDB mistakenly
	thinks the watchpoint triggered.  Vis, using foll-fork.c:

	  (gdb) awatch v
	  Hardware access (read/write) watchpoint 2: v
	  (gdb) catch fork
	  Catchpoint 3 (fork)
	  (gdb) c
	  Continuing.

	  Hardware access (read/write) watchpoint 2: v

	  Old value = 0
	  New value = 5
	  main () at gdb.base/foll-fork.c:16
	  16        pid = fork ();
	  (gdb)
	  Continuing.

	  Hardware access (read/write) watchpoint 2: v      <<<<
	                                                    <<<< these lines are spurious
	  Value = 5                                         <<<<

	  Catchpoint 3 (forked process 1712369), arch_fork (ctid=0x7ffff7fa4810) at arch-fork.h:49
	  49      arch-fork.h: No such file or directory.
	  (gdb)

	The problem is that when we handle the fork event, nothing called
	watchpoints_triggered before calling bpstat_stop_status.  Thus, each
	watchpoint's watchpoint_triggered field was still set to
	watch_triggered_yes from the previous (real) watchpoint stop.
	watchpoint_triggered is only current called in the handle_signal_stop
	path, when handling TARGET_WAITKIND_STOPPED.

	This fixes it by adding watchpoint_triggered calls in the other events
	paths that call bpstat_stop_status.  But instead of adding them
	explicitly, it adds a new function bpstat_stop_status_nowatch that
	wraps bpstat_stop_status and calls watchpoint_triggered, and then
	replaces most calls to bpstat_stop_status with calls to
	bpstat_stop_status_nowatch.

	This required constifying watchpoints_triggered.

	New test included, which fails without the fix.

	gdb/x86: handle stap probe arguments in xmm registers
	On x86 machines with xmm register, and with recent versions of
	systemtap (and gcc?), it can occur that stap probe arguments will be
	placed into xmm registers.

	I notice this happening on a current Fedora Rawhide install with the
	following package versions installed:

	  $ rpm -q glibc systemtap gcc
	  glibc-2.35.9000-10.fc37.x86_64
	  systemtap-4.7~pre16468670g9f253544-1.fc37.x86_64
	  gcc-12.0.1-0.12.fc37.x86_64

	If I check the probe data in libc, I see this:

	  $ readelf -n /lib64/libc.so.6
	  ...
	  stapsdt              0x0000004d       NT_STAPSDT (SystemTap probe descriptors)
	    Provider: libc
	    Name: pthread_start
	    Location: 0x0000000000090ac3, Base: 0x00000000001c65c4, Semaphore: 0x0000000000000000
	    Arguments: 8@%xmm1 8@1600(%rbx) 8@1608(%rbx)
	  stapsdt              0x00000050       NT_STAPSDT (SystemTap probe descriptors)
	    Provider: libc
	    Name: pthread_create
	    Location: 0x00000000000912f1, Base: 0x00000000001c65c4, Semaphore: 0x0000000000000000
	    Arguments: 8@%xmm1 8@%r13 8@8(%rsp) 8@16(%rsp)
	  ...

	Notice that for both of these probes, the first argument is a uint64_t
	stored in the xmm1 register.

	Unfortunately, if I try to use this probe within GDB, then I can't
	view the first argument.  Here's an example session:

	  $ gdb $(which gdb)
	  (gdb) start
	  ...
	  (gdb) info probes stap  libc pthread_create
	  ...
	  (gdb) break *0x00007ffff729e2f1       # Use address of probe.
	  (gdb) continue
	  ...
	  (gdb) p $_probe_arg0
	  Invalid cast.

	What's going wrong?  If I re-run my session, but this time use 'set
	debug stap-expression 1', this is what I see:

	  (gdb) set debug stap-expression 1
	  (gdb) p $_probe_arg0
	  Operation: UNOP_CAST
	   Operation: OP_REGISTER
	    String: xmm1
	   Type: uint64_t
	  Operation: UNOP_CAST

	  (gdb)

	The important bit is this:

	  Operation: UNOP_CAST
	   Operation: OP_REGISTER
	    String: xmm1
	   Type: uint64_t

	Which is where we cast the xmm1 register to uint64_t.  And the final
	piece of the puzzle is:

	  (gdb) ptype $xmm1
	  type = union vec128 {
	      v8bf16 v8_bfloat16;
	      v4f v4_float;
	      v2d v2_double;
	      v16i8 v16_int8;
	      v8i16 v8_int16;
	      v4i32 v4_int32;
	      v2i64 v2_int64;
	      uint128_t uint128;
	  }

	So, we are attempting to cast a union type to a scalar type, which is
	not supporting in C/C++, and as a consequence GDB's expression
	evaluator throws an error when we attempt to do this.

	The first approach I considered for solving this problem was to try
	and make use of gdbarch_stap_adjust_register.  We already have a
	gdbarch method (gdbarch_stap_adjust_register) that allows us to tweak
	the name of the register that we access.  Currently only x86
	architectures use this to transform things like ax to eax in some
	cases.

	I wondered, what if we change gdbarch_stap_adjust_register to do more
	than just change the register names?  What if this method instead
	became gdbarch_stap_read_register.  This new method would return a
	operation_up, and would take the register name, and the type we are
	trying to read from the register, and return the operation that
	actually reads the register.

	The default implementation of this method would just use
	user_reg_map_name_to_regnum, and then create a register_operation,
	like we already do in stap_parse_register_operand.  But, for x86
	architectures this method would fist possibly adjust the register
	name, then do the default action to read the register.  Finally, for
	x86 this method would spot when we were accessing an xmm register,
	and, based on the type being pulled from the register, would extract
	the correct field from the union.

	The benefit of this approach is that it would work with the expression
	types that GDB currently supports.  The draw back would be that this
	approach would not be very generic.  We'd need code to handle each
	sub-field size with an xmm register.  If other architectures started
	using vector registers for probe arguments, those architectures would
	have to create their own gdbarch_stap_read_register method.  And
	finally, the type of the xmm registers comes from the type defined in
	the target description, there's a risk that GDB might end up
	hard-coding the names of type sub-fields, then if a target uses a
	different target description, with different field names for xmm
	registers, the stap probes would stop working.

	And so, based on all the above draw backs, I rejected this first
	approach.

	My second plan involves adding a new expression type to GDB called
	unop_extract_operation.  This new expression takes a value and a type,
	during evaluation the value contents are fetched, and then a new value
	is extracted from the value contents (based on type).  This is similar
	to the following C expression:

	  result_value = *((output_type *) &input_value);

	Obviously we can't actually build this expression in this case, as the
	input_value is in a register, but hopefully the above makes it clearer
	what I'm trying to do.

	The benefit of the new expression approach is that this code can be
	shared across all architectures, and it doesn't care about sub-field
	names within the union type.

	The draw-backs that I see are potential future problems if arguments
	are not stored within the least significant bytes of the register.
	However if/when that becomes an issue we can adapt the
	gdbarch_stap_read_register approach to allow architectures to control
	how a value is extracted.

	For testing, I've extended the existing gdb.base/stap-probe.exp test
	to include a function that tries to force an argument into an xmm
	register.  Obviously, that will only work on a x86 target, so I've
	guarded the new function with an appropriate GCC define.  In the exp
	script we use readelf to check if the probe exists, and is using the
	xmm register.

	If the probe doesn't exist then the associated tests are skipped.

	If the probe exists, put isn't using the xmm register (which will
	depend on systemtap/gcc versions), then again, the tests are skipped.

	Otherwise, we can run the test.  I think the cost of running readelf
	is pretty low, so I don't feel too bad making all the non-xmm targets
	running this step.

	I found that on a Fedora 35 install, with these packages installed, I
	was able to run this test and have the probe argument be placed in an
	xmm register:

	  $ rpm -q systemtap gcc glibc
	  systemtap-4.6-4.fc35.x86_64
	  gcc-11.2.1-9.fc35.x86_64
	  glibc-2.34-7.fc35.x86_64

	Finally, as this patch adds a new operation type, then I need to
	consider how to generate an agent expression for the new operation
	type.

	I have kicked the can down the road a bit on this.  In the function
	stap_parse_register_operand, I only create a unop_extract_operation in
	the case where the register type is non-scalar, this means that in
	most cases I don't need to worry about generating an agent expression
	at all.

	In the xmm register case, when an unop_extract_operation will be
	created, I have sketched out how the agent expression could be
	handled, however, this code is currently not reached.  When we try to
	generate the agent expression to place the xmm register on the stack,
	GDB hits this error:

	  (gdb) trace -probe-stap test:xmmreg
	  Tracepoint 1 at 0x401166
	  (gdb) actions
	  Enter actions for tracepoint 1, one per line.
	  End with a line saying just "end".
	  >collect $_probe_arg0
	  Value not scalar: cannot be an rvalue.

	This is because GDB doesn't currently support placing non-scalar types
	on the agent expression evaluation stack.  Solving this is clearly
	related to the original problem, but feels a bit like a second
	problem.  I'd like to get feedback on whether my approach to solving
	the original problem is acceptable or not before I start looking at
	how to handle xmm registers within agent expressions.

	x86: don't suppress overflow diagnostics in x32 mode
	Unlike in 64-bit mode, where values wrap at the 64-bit boundary anyway,
	there's no wrapping at the 32-bit boundary here, and hence overflow
	detection shouldn't be suppressed just because rela relocations are
	going to be used.

	The extra check against NO_RELOC is actually a result of an ilp32 test
	otherwise failing. But thinking about it, reporting overflows for
	not-really-relocations (typically because of earlier errors) makes
	little sense in general. Perhaps this should even be extended to non-
	64-bit modes.

	[gdb/testsuite] test a function call by hand from pretty printer
	The test case added here is testing the bug gdb/28856, where calling a
	function by hand from a pretty printer makes GDB crash. There are 6
	mechanisms to trigger this crash in the current test, using the commands
	backtrace, up, down, finish, step and continue. Since the failure happens
	because of use-after-free (more details below) the tests will always
	have a chance of passing through sheer luck, but anecdotally they seem
	to fail all of the time.

	The reason GDB is crashing is a use-after-free problem. The above
	mentioned functions save a pointer to the current frame's information,
	then calls the pretty printer, and uses the saved pointer for different
	reasons, depending on the function. The issue happens because
	call_function_by_hand needs to reset the obstack to get the current
	frame, invalidating the saved pointer.

	gdb/testsuite: Installed-GDB testing & data-directory
	In testsuite/README, we suggest that you can run the testsuite against
	some other GDB binary by using:

	    make check RUNTESTFLAGS=GDB=/usr/bin/gdb

	However, that example isn't fully correct, because with that command
	line, the testsuite will still pass

	  -data-directory=[pwd]/../data-directory

	to /usr/bin/gdb, like e.g.:

	  ...
	  builtin_spawn /usr/bin/gdb -nw -nx -data-directory /home/pedro/gdb/build/gdb/testsuite/../data-directory -iex set height 0 -iex set width 0
	  ...

	while if you're testing an installed GDB (the system GDB being the
	most usual scenario), then you should normally let it use its own
	configured directory, not the just-built GDB's data directory.

	This commit improves the status quo with the following two changes:

	 - if the user specifies GDB on the command line, then by default,
	   don't start GDB with the -data-directory command line option.
	   I.e., let the tested GDB use its own configured data directory.

	 - let the user override the data directory, via a new
	   GDB_DATA_DIRECTORY global.  This replaces the existing
	   BUILD_DATA_DIRECTORY variable in testsuite/lib/gdb.exp, which
	   wasn't overridable, and was a bit misnamed for the new purpose.

	So after this, the following commands I believe behave intuitively:

	 # Test the non-installed GDB in some build dir:

	    make check \
	      RUNTESTFLAGS="GDB=/path/to/other/build/gdb \
	                    GDB_DATA_DIRECTORY=/path/to/other/build/gdb/data-directory"

	 # Test the GDB installed in some prefix:

	    make check \
	      RUNTESTFLAGS="GDB=/opt/gdb/bin/gdb"

	 # Test the built GDB with some alternative data directory, e.g., the
	   system GDB's data directory:

	    make check \
	      RUNTESTFLAGS="GDB_DATA_DIRECTORY=/usr/share/gdb"

	gdb/python: remove gdb._mi_commands dict
	The motivation for this patch is the fact that py-micmd.c doesn't build
	with Python 2, due to PyDict_GetItemWithError being a Python 3-only
	function:

	      CXX    python/py-micmd.o
	    /home/smarchi/src/binutils-gdb/gdb/python/py-micmd.c: In function ‘int micmdpy_uninstall_command(micmdpy_object*)’:
	    /home/smarchi/src/binutils-gdb/gdb/python/py-micmd.c:430:20: error: ‘PyDict_GetItemWithError’ was not declared in this scope; did you mean ‘PyDict_GetItemString’?
	      430 |   PyObject *curr = PyDict_GetItemWithError (mi_cmd_dict.get (),
	          |                    ^~~~~~~~~~~~~~~~~~~~~~~
	          |                    PyDict_GetItemString

	A first solution to fix this would be to try to replace
	PyDict_GetItemWithError equivalent Python 2 code.  But I looked at why
	we are doing this in the first place: it is to maintain the
	`gdb._mi_commands` Python dictionary that we use as a `name ->
	gdb.MICommand object` map.  Since the `gdb._mi_commands` dictionary is
	never actually used in Python, it seems like a lot of trouble to use a
	Python object for this.

	My first idea was to replace it with a C++ map
	(std::unordered_map<std::string, gdbpy_ref<micmdpy_object>>).  While
	implementing this, I realized we don't really need this map at all.  The
	mi_command_py objects registered in the main MI command table can own
	their backing micmdpy_object (that's a gdb.MICommand, but seen from the
	C++ code).  To know whether an mi_command is an mi_command_py, we can
	use a dynamic cast.  Since there's one less data structure to maintain,
	there are less chances of messing things up.

	 - Change mi_command_py::m_pyobj to a gdbpy_ref, the mi_command_py is
	   now what keeps the MICommand alive.
	 - Set micmdpy_object::mi_command in the constructor of mi_command_py.
	   If mi_command_py manages setting/clearing that field in
	   swap_python_object, I think it makes sense that it also takes care of
	   setting it initially.
	 - Move a bunch of checks from micmdpy_install_command to
	   swap_python_object, and make them gdb_asserts.
	 - In micmdpy_install_command, start by doing an mi_cmd_lookup.  This is
	   needed to know whether there's a Python MI command already registered
	   with that name.  But we can already tell if there's a non-Python
	   command registered with that name.  Return an error if that happens,
	   rather than waiting for insert_mi_cmd_entry to fail.  Change the
	   error message to "name is already in use" rather than "may already be
	   in use", since it's more precise.

	I asked Andrew about the original intent of using a Python dictionary
	object to hold the command objects.  The reason was to make sure the
	objects get destroyed when the Python runtime gets finalized, not later.
	Holding the objects in global C++ data structures and not doing anything
	more means that the held Python objects will be decref'd after the
	Python interpreter has been finalized.  That's not desirable.  I tried
	it and it indeed segfaults.

	Handle this by adding a gdbpy_finalize_micommands function called in
	finalize_python.  This is the mirror of gdbpy_initialize_micommands
	called in do_start_initialization.  In there, delete all Python MI
	commands.  I think it makes sense to do it this way: if it was somehow
	possible to unload Python support from GDB in the middle of a session
	we'd want to unregister any Python MI command.  Otherwise, these MI
	commands would be backed with a stale PyObject or simply nothing.

	Delete tests that were related to `gdb._mi_commands`.

	This instruction modifies the frame base calculation, and so the test

	but it's also worth noting that this test passes for aarch64 in some
	configurations -- I don't know what causes one to fail and another to
	succeed.

	x86: also fold remaining multi-vector-size shift insns
	By slightly relaxing the checking in operand_type_register_match() we
	can fold the vector shift insns with an XMM source as well. While
	strictly speaking an overlap in just one size (see the code comment) is
	not enough (both operands could have multiple sizes with just a single
	common one), this is good enough for all templates we have, or which
	could sensibly / usefully appear (within the scope of the present
	operand matching model).

	Tightening this a little would be possible, but would require broadcast
	related information to be passed into the function.

	x86: don't accept base architectures as extensions
	The -march= intentions are quite clear: A base architecture may be
	followed by any number of extensions. Accepting a base architecture in
	place of an extension will at best result in confusion, as the first of
	the two (or more) items specified simply would not take effect, due to
	being overridden by the later one(s).

	x86: never set i386_cpu_flags' "unused" field
	Setting this field risks cpu_flags_all_zero() mistakenly returning
	"false" when the object passed in was e.g. the result of ANDing together
	two objects which had the bit set, or ANDNing together an object with
	the field set and one with the field clear.

	While there also avoid setting CpuNo64: Like Cpu64 this is driven
	differently anyway and hence shouldn't be set anywhere by default.

	Note that the moving of the two items in i386-gen.c's cpu_flags[] is
	only for documentation purposes (and slight reducing of overhead), as
	the fields are sorted anyway upon program start.

	While there exclude CpuIAMCU from CPU_UNKNOWN_FLAGS - CPU_IAMCU_FLAGS

	architecture cannot be changed.

	x86: drop L1OM/K1OM support from gas
	This was only rudimentary support anyway; none of the sub-architecture
	specific insns were ever supported.

	x86: assorted IAMCU CPU checking fixes
	The checks done by check_cpu_arch_compatible() were halfway sensible
	only at the time where only L1OM support was there. The purpose,
	however, has always been to prevent bad uses of .arch (turning off the
	base CPU "feature" flag) while at the same time permitting extensions to
	be enabled / disabled. In order to achieve this (and to prevent
	regressions when L1OM and K1OM support are removed)
	- set CpuIAMCU in CPU_IAMCU_FLAGS,
	- adjust the IAMCU check in the function itself (the other two similarly
	  broken checks aren't adjusted as they're slated to be removed anyway),
	- avoid calling the function for extentions (which would never have the
	  base "feature" flag set),
	- add a new testcase actually exercising ".arch iamcu" (which would also
	  regress with the planned removal).

	gdb: work around prompt corruption caused by bracketed-paste-mode
	In this commit:

	  commit b4f26d541aa7224b70d363932e816e6e1a857633
	  Date:   Tue Mar 2 13:42:37 2021 -0700

	      Import GNU Readline 8.1

	We imported readline 8.1 into GDB.  As a consequence bug PR cli/28833
	was reported.  This bug spotted that, when the user terminated GDB by
	sending EOF (usually bound to Ctrl+d), the last prompt would become
	corrupted.  Here's what happens, the user is sat at a prompt like
	this:

	  (gdb)

	And then the user sends EOF (Ctrl+d), we now see this:

	  quit)
	  ... gdb terminates, and we return to the shell ...

	Notice the 'quit' was printed over the prompt.

	This problem is a result of readline 8.1 enabling bracketed paste mode
	by default.  This problem is present in readline 8.0 too, but in that
	version of readline bracketed paste mode is off by default, so a user
	will not see the bug unless they specifically enable the feature.

	Bracketed paste mode is available in readline 7.0 too, but the bug
	is not present in this version of readline, see below for why.

	What causes this problem is how readline disables bracketed paste
	mode.  Bracketed paste mode is a terminal feature that is enabled and
	disabled by readline emitting a specific escape sequence.  The problem
	for GDB is that the escape sequence to disable bracketed paste mode
	includes a '\r' character at the end, see this thread for more
	details:

	  https://lists.gnu.org/archive/html/bug-bash/2018-01/msg00097.html

	The change to add the '\r' character to the escape sequence used to
	disable bracketed paste mode was introduced between readline 7.0 and
	readline 8.0, this is why the bug would not occur when using older
	versions of readline (note: I don't know if its even possible to build
	GDB using readline 7.0.  That really isn't important, I'm just
	documenting the history of this issue).

	So, the escape sequence to disable bracketed paste mode is emitted
	from the readline function rl_deprep_terminal, this is called after
	the user has entered a complete command and pressed return, or, if the
	user sends EOF.

	However, these two cases are slightly different.  In the first case,
	when the user has entered a command and pressed return, the cursor
	will have moved to the next, empty, line, before readline emits the
	escape sequence to leave bracketed paste mode.  The final '\r'
	character moves the cursor back to the beginning of this empty line,
	which is harmless.

	For the EOF case though, this is not what happens.  Instead, the
	escape sequence to leave bracketed paste mode is emitted on the same
	line as the prompt.  The final '\r' moves the cursor back to the start
	of the prompt line.  This leaves us ready to override the prompt.

	It is worth noting, that this is not the intended behaviour of
	readline, in rl_deprep_terminal, readline should emit a '\n' character
	when EOF is seen.  However, due to a bug in readline this does not
	happen (the _rl_eof_found flag is never set).  This is the first
	readline bug that effects GDB.

	GDB prints the 'quit' message from command_line_handler (in
	event-top.c), this function is called (indirectly) from readline to
	process the complete command line, but also in the EOF case (in which
	case the command line is set to nullptr).  As this is part of the
	callback to process a complete command, this is called after readline
	has disabled bracketed paste mode (by calling rl_deprep_terminal).

	And so, when bracketed paste mode is in use, rl_deprep_terminal leaves
	the cursor at the start of the prompt line (in the EOF case), and
	command_line_handler then prints 'quit', which overwrites the prompt.

	The solution to this problem is to print the 'quit' message earlier,
	before rl_deprep_terminal is called.  This is easy to do by using the
	rl_deprep_term_function hook.  It is this hook that usually calls
	rl_deprep_terminal, however, if we replace this with a new function,
	we can print the 'quit' string, and then call rl_deprep_terminal
	ourselves.  This allows the 'quit' to be printed before
	rl_deprep_terminal is called.

	The problem here is that there is no way in rl_deprep_terminal to know
	if readline is processing EOF or not, and as a result, we don't know
	when we should print 'quit'.  This is the second readline bug that
	effects GDB.

	Both of these readline issues are discussed in this thread:

	  https://lists.gnu.org/archive/html/bug-readline/2022-02/msg00021.html

	The result of that thread was that readline was patched to address
	both of these issues.

	Now it should be easy to backport the readline fix to GDB's in tree
	copy of readline, and then change GDB to make use of these fixes to
	correctly print the 'quit' string.

	However, we are just about to branch GDB 12, and there is concern from
	some that changing readline this close to a new release is a risky
	idea, see this thread:

	  https://sourceware.org/pipermail/gdb-patches/2022-March/186391.html

	So, this commit doesn't change readline at all.  Instead, this commit
	is the smallest possible GDB change in order to avoid the prompt
	corruption.

	In this commit I change GDB to print the 'quit' string on the line
	after the prompt, but only when bracketed paste mode is on.  This
	avoids the overwriting issue, the user sees this:

	  (gdb)
	  quit
	  ... gdb terminates, and returns to the shell ...

	This isn't ideal, but is better than the existing behaviour.  After
	GDB 12 has branched, we can backport the readline fix, and apply a
	real fix to GDB.

	Reimplement array concatenation for Ada and D
	This started as a patch to implement string concatenation for Ada.
	However, while working on this, I looked at how this code could
	possibly be called.  It turns out there are only two users of
	concat_operation: Ada and D.  So, in addition to implementing this for
	Ada, this patch rewrites value_concat, removing the odd "concatenate
	or repeat" semantics, which were completely unused.  As Ada and D both
	seem to represent strings using TYPE_CODE_ARRAY, this removes the
	TYPE_CODE_STRING code from there as well.

	Remove eval_op_concat
	eval_op_concat has code to search for an operator overload of
	BINOP_CONCAT.  However, the operator overloading code is specific to
	C++, which does not have this operator.  And,
	binop_types_user_defined_p rejects this case right at the start, and
	value_x_binop does not handle this case.  I think this code has been
	dead for a very long time.  This patch removes it and hoists the
	remaining call into concatenation::evaluate, removing eval_op_concat
	entirely.

	The patch updates an existing test case.  Note that another test,
	namely something like:

	    ptype Wide_Wide_String'("literal")

	... would be nice to add, but when tested against a distro GNAT, this
	did not work (probably due to lack of debuginfo); so, I haven't
	included it here.

	Powerpc fix for gdb.base/ending-run.exp
	The last two tests in gdb.base/ending-run.exp case fail on Powerpc when the
	system does not have the needed glibc debug-info files loaded.  In this
	case, gdb is not able to determine where execution stopped.  This behavior
	looks as follows for the test case:

	The next to the last test does a next command when the program is stopped
	at the closing bracket for main.  The message printed is:

	0x00007ffff7d01524 in ?? () from /lib/powerpc64le-linux-gnu/libc.so.6

	which fails to match any of the test_multiple options.

	The test then does another next command.  On Powerpc, the
	message printed it:

	Cannot find bounds of current function

	The test fails as the output does not match any of the options for the
	gdb_test_multiple.

	I checked the behavior on Powerpc to see if this is typical.
	I ran gdb on the following simple program as shown below.

	#include <stdio.h>
	int
	main(void)
	{
	  printf("Hello, world!\n");
	  return 0;
	}

	So it would seem that the messages seen from the test case are
	"normal" output for Powerpc when the debug-info is not available.

	The following patch adds the output from Powerpc as an option
	to the gdb_test_multiple statement, identifying the output as the expected
	output on Powerpc without the needed debug-info files installed.

	The patch has been tested on a Power 10 system and an Intel
	64-bit system.  No additional regression failures were seen on
	either platform.

	gdb/mi: consistently notify user when GDB/MI client uses -thread-select
	GDB notifies users about user selected thread changes somewhat
	inconsistently as mentioned on gdb-patches mailing list here:

	  https://sourceware.org/pipermail/gdb-patches/2022-February/185989.html

	Consider GDB debugging a multi-threaded inferior with both CLI and GDB/MI
	interfaces connected to separate terminals.

	Assuming inferior is stopped and thread 1 is selected, when a thread
	2 is selected using '-thread-select 2' command on GDB/MI terminal:

	    -thread-select 2
	    ^done,new-thread-id="2",frame={level="0",addr="0x00005555555551cd",func="child_sub_function",args=[],file="/home/jv/Projects/gdb/users_jv_patches/gdb/testsuite/gdb.mi/user-selected-context-sync.c",fullname="/home/uuu/gdb/gdb/testsuite/gdb.mi/user-selected-context-sync.c",line="30",arch="i386:x86-64"}
	    (gdb)

	and on CLI terminal we get the notification (as expected):

	    [Switching to thread 2 (Thread 0x7ffff7daa640 (LWP 389659))]
	    #0  child_sub_function () at /home/uuu/gdb/gdb/testsuite/gdb.mi/user-selected-context-sync.c:30
	    30        volatile int dummy = 0;

	However, now that thread 2 is selected, if thread 1 is selected
	using 'thread-select --thread 1 1' command on GDB/MI terminal
	terminal:

	   -thread-select --thread 1 1
	   ^done,new-thread-id="1",frame={level="0",addr="0x0000555555555294",func="main",args=[],file="/home/jv/Projects/gdb/users_jv_patches/gdb/testsuite/gdb.mi/user-selected-context-sync.c",fullname="/home/jv/Projects/gdb/users_jv_patches/gdb/testsuite/gdb.mi/user-selected-context-sync.c",line="66",arch="i386:x86-64"}
	   (gdb)

	but no notification is printed on CLI terminal, despite the fact
	that user selected thread has changed.

	The problem is that when `-thread-select --thread 1 1` is executed
	then thread is switched to thread 1 before mi_cmd_thread_select () is
	called, therefore the condition "inferior_ptid != previous_ptid"
	there does not hold.

	To address this problem, we have to move notification logic up to
	mi_cmd_execute () where --thread option is processed and notify
	user selected contents observers there if context changes.

	However, this in itself breaks GDB/MI because it would cause context
	notification to be sent on MI channel. This is because by the time
	we notify, MI notification suppression is already restored (done in
	mi_command::invoke(). Therefore we had to lift notification suppression
	logic also up to mi_cmd_execute (). This change in made distinction
	between mi_command::invoke() and mi_command::do_invoke() unnecessary
	as all mi_command::invoke() did (after the change) was to call
	do_invoke(). So this patches removes do_invoke() and moves the command
	execution logic directly to invoke().

	With this change, all gdb.mi tests pass, tested on x86_64-linux.

	binutils/readelf: build against msgpack, dump NT_AMDGPU_METADATA note contents
	The AMDGPU HSA OS ABI (code object v3 and above) defines the
	NT_AMDGPU_METADATA ELF note [1].  The content is a msgpack object
	describing, among other things, the kernels present in the code object
	and how to call them.

	I think it would be useful for readelf to be able to display the content
	of those notes.  msgpack is a structured format, a bit like JSON, except
	not text-based.  It is therefore possible to dump the contents in
	human-readable form without knowledge of the specific layout of the
	note.

	Add configury to binutils to optionally check for the msgpack C library
	[2].  Add There is a new --with{,out}-msgpack configure flag, and the actual
	library lookup is done using pkg-config.

	If msgpack support is enabled, dumping a NT_AMDGPU_METADATA note looks
	like:

	    $ readelf --notes amdgpu-code-object
	    Displaying notes found in: .note
	      Owner                Data size        Description
	      AMDGPU               0x0000040d       NT_AMDGPU_METADATA (code object metadata)
	        {
	          "amdhsa.kernels": [
	            {
	              ".args": [
	                {
	                  ".address_space": "global",
	                  ".name": "out.coerce",
	                  ".offset": 0,
	                  ".size": 8,
	                  ".value_kind": "global_buffer",
	                },
	      <snip>

	If msgpack support is disabled, dump the contents as hex, as is done
	with notes that are not handled in a special way.  This allows one to
	decode the contents manually (maybe using a command-line msgpack
	decoder) if really needed.

	binutils/readelf: decode AMDGPU-specific e_flags
	Decode and print the AMDGPU-specific fields of e_flags, as documented
	here:

	  https://llvm.org/docs/AMDGPUUsage.html#header

	That is:

	 - The specific GPU model
	 - Whether the xnack and sramecc features are enabled

	The result looks like:

	-  Flags:                             0x52f
	+  Flags:                             0x52f, gfx906, xnack any, sramecc any

	The flags for the "HSA" OS ABI are properly versioned and documented on
	that page.  But the NONE, PAL and MESA3D OS ABIs are not well documented
	nor versioned.  Taking a peek at the LLVM source code, we see that they
	encode their flags the same way as HSA v3.  For example, for PAL:

	  https://github.com/llvm/llvm-project/blob/c8b614cd74a92d85936aed5ac7c642af75ffdc29/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp#L601

2022-03-16  Pedro Alves  <pedro@palves.net>

	Make gdb.fortran/{array-slices,lbound-ubound} work against gdbserver
	gdb.fortran/array-slices.exp and gdb.fortran/lbound-ubound.exp were
	recently disabled unless testing with the native target, because they
	rely on inferior I/O.  However, when testing against gdbserver using
	the native-gdbserver/native-extended-gdbserver boards, we do have
	access to inferior I/O.

	The right way to check whether the board can do I/O, is via checking
	the gdb,noinferiorio board variable.  Switch to using that.

	And then, tweak the testcases to expect output to appear in
	inferior_spawn_id, instead of gdb_spawn_id.  When testing against the
	native target, inferior_spawn_id is the same as gdb_spawn_id.  When
	testing against gdbserver, it maps to gdbserver_spawn_id.

	This exposed a buglet in gdb.fortran/array-slices.f90's show_1d
	subroutine -- it was missing printing newline at the end of the
	"Expected GDB Output" text, leading to a test timeout.  All other
	subroutines end with advance=yes, except this one.  Fix it by using
	advance=yes here too.

	PowerPC64 extended instructions in powerpc_macros
	The extended instructions implemented in powerpc_macros aren't used by
	the disassembler.  That means instructions like "sldi r3,r3,2" appear
	in disassembly as "rldicr r3,r3,2,61", which is annoying since many
	other extended instructions are shown.

	Note that some of the instructions moved out of the macro table to the
	opcode table won't appear in disassembly, because they are aliases
	rather than a subset of the underlying raw instruction.  If enabled,
	rotrdi, extrdi, extldi, clrlsldi, and insrdi would replace all
	occurrences of rotldi, rldicl, rldicr, rldic and rldimi.  (Or many

	gdb/testsuite: rename a proc and fix a typo
	Rename a proc in gdb.mi/user-selected-context-sync.exp, I think the
	old name was most likely a typo.  The old name
	match_re_or_ensure_not_output seems (to me) to imply we're in some way
	checking that the regexp was not output.  But that's not what we are
	doing, we're checking either for the regexp, or for no output, hence
	the new name match_re_or_ensure_no_output.

	Additionally, I found a definite typo in one of the comments that I've
	also fixed.

	I also updated some test names.  These tests (probably due to copy &
	paste errors) has 'on MI' on their name, when they were actually
	checking CLI output.  For these test I changed the name to use 'on
	CLI'.

	There should be no change in what is tested after this commit.

	gdb/python/mi: create MI commands using python
	This commit allows a user to create custom MI commands using Python
	similarly to what is possible for Python CLI commands.

	A new subclass of mi_command is defined for Python MI commands,
	mi_command_py. A new file, gdb/python/py-micmd.c contains the logic
	for Python MI commands.

	This commit is based on work linked too from this mailing list thread:

	  https://sourceware.org/pipermail/gdb/2021-November/049774.html

	Which has also been previously posted to the mailing list here:

	  https://sourceware.org/pipermail/gdb-patches/2019-May/158010.html

	And was recently reposted here:

	  https://sourceware.org/pipermail/gdb-patches/2022-January/185190.html

	The version in this patch takes some core code from the previously
	posted patches, but also has some significant differences, especially
	after the feedback given here:

	  https://sourceware.org/pipermail/gdb-patches/2022-February/185767.html

	A new MI command can be implemented in Python like this:

	  class echo_args(gdb.MICommand):
	      def invoke(self, args):
	          return { 'args': args }

	  echo_args("-echo-args")

	The 'args' parameter (to the invoke method) is a list
	containing (almost) all command line arguments passed to the MI
	command (--thread and --frame are handled before the Python code is
	called, and removed from the args list).  This list can be empty if
	the MI command was passed no arguments.

	When used within gdb the above command produced output like this:

	  (gdb)
	  -echo-args a b c
	  ^done,args=["a","b","c"]
	  (gdb)

	The 'invoke' method of the new command must return a dictionary.  The
	keys of this dictionary are then used as the field names in the mi
	command output (e.g. 'args' in the above).

	The values of the result returned by invoke can be dictionaries,
	lists, iterators, or an object that can be converted to a string.
	These are processed recursively to create the mi output.  And so, this
	is valid:

	  class new_command(gdb.MICommand):
	      def invoke(self,args):
	          return { 'result_one': { 'abc': 123, 'def': 'Hello' },
	                   'result_two': [ { 'a': 1, 'b': 2 },
	                                   { 'c': 3, 'd': 4 } ] }

	Which produces output like:

	  (gdb)
	  -new-command
	  ^done,result_one={abc="123",def="Hello"},result_two=[{a="1",b="2"},{c="3",d="4"}]
	  (gdb)

	I have required that the fields names used in mi result output must
	match the regexp: "^[a-zA-Z][-_a-zA-Z0-9]*$" (without the quotes).
	This restriction was never written down anywhere before, but seems
	sensible to me, and we can always loosen this rule later if it proves
	to be a problem.  Much harder to try and add a restriction later, once
	people are already using the API.

	What follows are some details about how this implementation differs
	from the original patch that was posted to the mailing list.

	In this patch, I have changed how the lifetime of the Python
	gdb.MICommand objects is managed.  In the original patch, these object
	were kept alive by an owned reference within the mi_command_py object.
	As such, the Python object would not be deleted until the
	mi_command_py object itself was deleted.

	This caused a problem, the mi_command_py were held in the global mi
	command table (in mi/mi-cmds.c), which, as a global, was not cleared
	until program shutdown.  By this point the Python interpreter has
	already been shutdown.  Attempting to delete the mi_command_py object
	at this point was causing GDB to try and invoke Python code after
	finalising the Python interpreter, and we would crash.

	To work around this problem, the original patch added code in
	python/python.c that would search the mi command table, and delete the
	mi_command_py objects before the Python environment was finalised.

	In contrast, in this patch, I have added a new global dictionary to
	the gdb module, gdb._mi_commands.  We already have several such global
	data stores related to pretty printers, and frame unwinders.

	The MICommand objects are placed into the new gdb.mi_commands
	dictionary, and it is this reference that keeps the objects alive.
	When GDB's Python interpreter is shut down gdb._mi_commands is deleted,
	and any MICommand objects within it are deleted at this point.

	This change avoids having to make the mi_cmd_table global, and walk
	over it from within GDB's python related code.

	This patch handles command redefinition entirely within GDB's python
	code, though this does impose one small restriction which is not
	present in the original code (detailed below), I don't think this is a
	big issue.  However, the original patch relied on being able to
	finish executing the mi_command::do_invoke member function after the
	mi_command object had been deleted.  Though continuing to execute a
	member function after an object is deleted is well defined, it is
	also (IMHO) risky, its too easy for someone to later add a use of the
	object without realising that the object might sometimes, have been
	deleted.  The new patch avoids this issue.

	The one restriction that is added to avoid this, is that an MICommand
	object can't be reinitialised with a different command name, so:

	  (gdb) python cmd = MyMICommand("-abc")
	  (gdb) python cmd.__init__("-def")
	  can't reinitialize object with a different command name

	This feels like a pretty weird edge case, and I'm happy to live with
	this restriction.

	I have also changed how the memory is managed for the command name.
	In the most recently posted patch series, the command name is moved
	into a subclass of mi_command, the python mi_command_py, which
	inherits from mi_command is then free to use a smart pointer to manage
	the memory for the name.

	In this patch, I leave the mi_command class unchanged, and instead
	hold the memory for the name within the Python object, as the lifetime
	of the Python object always exceeds the c++ object stored in the
	mi_cmd_table.  This adds a little more complexity in py-micmd.c, but
	leaves the mi_command class nice and simple.

	Next, this patch adds some extra functionality, there's a
	MICommand.name read-only attribute containing the name of the command,
	and a read-write MICommand.installed attribute that can be used to
	install (make the command available for use) and uninstall (remove the
	command from the mi_cmd_table so it can't be used) the command.  This
	attribute will be automatically updated if a second command replaces
	an earlier command.

	This patch adds additional error handling, and makes more use the
	gdbpy_handle_exception function.

	gdb/gdbarch: compare some fields against 0 verify_gdbarch
	After the previous commit, which removes the predicate function
	gdbarch_register_type_p, I noticed that the gdbarch->register_type
	field was not checked at in the verify_gdbarch function.

	More than not being checked, the field wasn't mentioned at all.

	I find this strange, I would expect that every field would at least be
	mentioned - we already generate comments for some fields saying that
	this field is _not_ being checked, so the fact that this field isn't
	being checked looks (to me), like this field is somehow slipping
	through the cracks.

	The comment at the top of gdbarch-components.py tries to explain how
	the validation is done.  I didn't understand this comment completely,
	but, I think this final sentence:

	  "Otherwise, the check is done against 0 (really NULL for function
	  pointers, but same idea)."

	Means that, if non of the other cases apply, then the field should be
	checked against 0, with 0 indicating that the field is invalid (was
	not set by the tdep code).  However, this is clearly not being done.

	Looking in gdbarch.py at the code to generate verify_gdbarch we do
	find that there is a case that is not handled, the case where the
	'invalid' field is set true True, but non of the other cases apply.

	In this commit I propose two changes:

	 1. Handle the case where the 'invalid' field of a property is set to
	 True, this should perform a check for the field of gdbarch still
	 being set to 0, and

	 2. If the if/else series that generates verify_gdbarch doesn't handle
	 a property then we should raise an exception.  This means that if a
	 property is added which isn't handled, we should no longer silently
	 ignore it.

	After doing this, I re-generated the gdbarch files and saw that the
	following gdbarch fields now had new validation checks:

	  register_type
	  believe_pcc_promotion
	  register_to_value
	  value_to_register
	  frame_red_zone_size
	  displaced_step_restore_all_in_ptid
	  solib_symbols_extension

	Looking at how these are currently set in the various -tdep.c files, I
	believe the only one of these that is required to be set for all
	architectures is the register_type field.

	And so, for all of the other fields, I've changed the property
	definition on gdbarch-components.py, setting the 'invalid' field to
	False.

	Now, after re-generation, the register_type field is checked against
	0, thus an architecture that doesn't set_gdbarch_register_type will
	now fail during validation.  For all the other fields we skip the
	validation, in which case, it is find for an architecture to not set
	this field.

	My expectation is that there should be no user visible changes after
	this commit.  Certainly for all fields except register_type, all I've
	really done is cause some extra comments to be generated, so I think
	that's clearly fine.

	For the register_type field, my claim is that any architecture that
	didn't provide this would fail when creating its register cache, and I
	couldn't spot an architecture that doesn't provide this hook.  As
	such, I think this change should be fine too.

2022-03-14  Andrew Burgess  <aburgess@redhat.com>

	gdb/gdbarch: remove the predicate function for gdbarch_register_type
	I don't believe that the gdbarch_register_type_p predicate is called
	anywhere in GDB, and the gdbarch_register_type function is called
	without checking the gdbarch_register_type_p predicate function
	everywhere it is used, for example in
	init_regcache_descr (regcache.c).

	My claim is that the gdbarch_register_type function is required for
	every architecture, and GDB will not work if this function is not
	supplied.

	And so, in this commit, I remove the 'predicate=True' from
	gdbarch-components.py for the 'register_type' field, and regenerate
	the gdbarch files.

	There should be no user visible changes after this commit.

	Replace deprecated_target_wait_hook by observers
	Commit b60cea7 (Make target_wait options use enum flags) broke
	deprecated_target_wait_hook usage: there's a commit comment telling
	this hook has not been converted.

	Rather than trying to mend it, this patch replaces the hook by two
	target_wait observers:

	target_pre_wait (ptid_t ptid)
	target_post_wait (ptid_t event_ptid)

	Upon target_wait entry, target_pre_wait is notified with the ptid
	passed to target_wait. Upon exit, target_post_wait is notified with
	the event ptid returned by target_wait. Should an exception occur,
	event_ptid is null_ptid.

	This change benefits to Insight (out-of-tree): there's no real use of the
	late hook in gdb itself.

	Correctly print subrange types in generic_value_print
	I noticed that generic_value_print assumes that a subrange type is
	always a subrange of an integer type.  However, this isn't necessarily
	the case.  In Ada, for example, one has subranges of character and
	enumeration types.

	This code isn't often exercised, I think, because languages with real
	subrange types tend to implement their own printers.  However, it
	still seemed worth fixing.

	[aarch64/arm] Properly extract the return value returned in memory
	When running gdb.cp/non-trivial-retval.exp, the following shows up for
	both aarch64-linux and armhf-linux:

	Breakpoint 3, f1 (i1=23, i2=100) at src/gdb/testsuite/gdb.cp/non-trivial-retval.cc:35
	35        A a;
	(gdb) finish
	Run till exit from #0  f1 (i1=23, i2=100) at src/gdb/testsuite/gdb.cp/non-trivial-retval.cc:35
	main () at /src/gdb/testsuite/gdb.cp/non-trivial-retval.cc:163
	163       B b = f2 (i1, i2);
	Value returned is $6 = {a = -11952}
	(gdb)

	The return value should be {a = 123} instead. This happens because the
	backends don't extract the return value from the correct location. GDB should
	fetch a pointer to the memory location from X8 for aarch64 and r0 for armhf.

	With the patch, gdb.cp/non-trivial-retval.exp has full passes on
	aarch64-linux and armhf-linux on Ubuntu 20.04/18.04.

	The problem only shows up with the "finish" command. The "call" command
	works correctly and displays the correct return value.

	This is also related to PR gdb/28681
	(https://sourceware.org/bugzilla/show_bug.cgi?id=28681) and fixes FAIL's in
	gdb.ada/mi_var_array.exp.

	A new testcase is provided, and it exercises GDB's ability to "finish" a
	function that returns a large struct (> 16 bytes) and display the
	contents of this struct correctly. This has always been incorrect for
	these backends, but no testcase exercised this particular scenario.

	What's happening here is that the core file lists some shared
	libraries.  These aren't available via the solib search path, and so
	gdb finds the local (x86-64) libraries.  This is not ideal, but on the
	other hand, it is what was asked for -- while the test does set
	solib-search-path, it does not set the sysroot.

	But, because gdb isn't configured to handle these libraries, it
	crashes.

	It seems to me that it's better to avoid the crash by having
	solib_bfd_open fail in the case where a library is incompatible.  That
	is what this patch does.  Now it looks like:

	    | [New LWP 15488]
	    | Error while mapping shared library sections:
	    | `/lib64/libc.so.6': Shared library architecture unknown is not compatible with target architecture powerpc:common64.

	... and does not crash gdb.

	I don't have a good setup for testing this using dejagnu, so I don't
	know whether an existing gdb test covers this scenario.

	Change how "print/x" displays floating-point value
	Currently, "print/x" will display a floating-point value by first
	casting it to an integer type.  This yields weird results like:

	    (gdb) print/x 1.5
	    $1 = 0x1

	This has confused users multiple times -- see PR gdb/16242, where
	there are several dups.  I've also seen some confusion from this
	internally at AdaCore.

	The manual says:

	    'x'
		 Regard the bits of the value as an integer, and print the integer
		 in hexadecimal.

	... which seems more useful.  So, perhaps what happened is that this
	was incorrectly implemented (or maybe correctly implemented and then
	regressed, as there don't seem to be any tests).

	This patch fixes the bug.

	There was a previous discussion where we agreed to preserve the old
	behavior:

	    https://sourceware.org/legacy-ml/gdb-patches/2017-06/msg00314.html

	Process exit status is leader exit status testcase
	This adds a multi-threaded testcase that has all threads in the
	process exit with a different exit code, and ensures that GDB reports
	the thread group leader's exit status as the whole-process exit
	status.  Before this set of patches, this would randomly report the
	exit code of some other thread, and thus fail.

	Tested on Linux-x86_64, native and gdbserver.

	Re-add zombie leader on exit, gdbserver/linux
	Same as the previous patch, but for GDBserver.

	In summary, the current zombie leader detection code in linux-low.cc
	has a race -- if a multi-threaded inferior exits just before
	check_zombie_leaders finds that the leader is now zombie via checking
	/proc/PID/status, check_zombie_leaders deletes the leader, assuming we
	won't get an event for that exit (which we won't in some scenarios,
	but not in this one), which is a false-positive scenario, where the
	whole process is simply exiting.  Later when we see the last LWP in
	our list exit, we report that LWP's exit status as exit code, even
	though for the (real) parent process, the exit code that counts is the
	child's leader thread's exit code.

	Like for GDB, the solution here is to:

	   - only report whole-process exit events for the leader.
	   - re-add the leader back to the LWP list when we finally see it
	     exit.

	Re-add zombie leader on exit, gdb/linux
	The current zombie leader detection code in linux-nat.c has a race --
	if a multi-threaded inferior exits just before check_zombie_leaders
	finds that the leader is now zombie via checking /proc/PID/status,
	check_zombie_leaders deletes the leader, assuming we won't get an
	event for that exit (which we won't in some scenarios, but not in this
	one).  That might seem mostly harmless, but it has some downsides:

	 - later when we continue pulling events out of the kernel, we will
	   collect the exit event of the non-leader threads, and once we see
	   the last lwp in our list exit, we return _that_ lwp's exit code as
	   whole-process exit code to infrun, instead of the leader's exit
	   code.

	 - this can cause a hang in stop_all_threads in infrun.c.  Say there
	   are 2 threads in the process.  stop_all_threads stops each of those
	   threads, and then waits for two stop or exit events, one for each
	   thread.  If the whole process exits, and check_zombie_leaders hits
	   the false-positive case, linux-nat.c will only return one event to
	   GDB (the whole-process exit returned when we see the last thread,
	   the non-leader thread, exit), making stop_all_threads hang forever
	   waiting for a second event that will never come.

	However, in this false-positive scenario, where the whole process is
	exiting, as opposed to just the leader (with pthread_exit(), for
	example), we _will_ get an exit event shortly for the leader, after we
	collect the exit event of all the other non-leader threads.  Or put
	another way, we _always_ get an event for the leader after we see it
	become zombie.

	I tried a number of approaches to fix this:

	#1 - My first thought to address the race was to make GDB always
	report the whole-process exit status for the leader thread, not for
	whatever is the last lwp in the list.  We _always_ get a final exit
	(or exec) event for the leader, and when the race triggers, we're not
	collecting it.

	#2 - My second thought was to try to plug the race in the first place.

	I thought of making GDB call waitpid/WNOHANG for all non-leader
	threads immediately when the zombie leader is detected, assuming there
	would be an exit event pending for each of them waiting to be
	collected.  Turns out that that doesn't work -- you can see the leader
	become zombie _before_ the kernel kills all other threads.  Waitpid in
	that small time window returns 0, indicating no-event.  Thankfully we
	hit that race window all the time, which avoided trading one race for
	another.  Looking at the non-leader thread's status in /proc doesn't
	help either, the threads are still in running state for a bit, for the
	same reason.

	#3 - My next attempt, which seemed promising, was to synchronously
	stop and wait for the stop for each of the non-leader threads.  For
	the scenario in question, this will collect all the exit statuses of
	the non-leader threads.  Then, if we are left with only the zombie
	leader in the lwp list, it means we either have a normal while-process
	exit or an exec, in which case we should not delete the leader.  If
	_only_ the leader exited, like in gdb.threads/leader-exit.exp, then
	after pausing threads, we will still have at least one live non-leader
	thread in the list, and so we delete the leader lwp.  I got this
	working and polished, and it was only after staring at the kernel code
	to convince myself that this would really work (and it would, for the
	scenario I considered), that I realized I had failed to account for
	one scenario -- if any non-leader thread is _already_ stopped when
	some thread triggers a group exit, like e.g., if you have some threads
	stopped and then resume just one thread with scheduler-locking or
	non-stop, and that thread exits the process.  I also played with
	PTRACE_EVENT_EXIT, see if it would help in any way to plug the race,
	and I couldn't find a way that it would result in any practical
	difference compared to looking at /proc/PID/status, with respect to
	having a race.

	So I concluded that there's no way to plug the race, we just have to
	deal with it.  Which means, going back to approach #1.  That is the
	approach taken by this patch.

	Fix gdb.threads/current-lwp-dead.exp race
	If we make GDB report the process EXIT event for the leader thread, as
	will be done in a latter patch of this series, then
	gdb.threads/current-lwp-dead.exp starts failing:

	 (gdb) break fn_return
	 Breakpoint 2 at 0x5555555551b5: file /home/pedro/rocm/gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.threads/current-lwp-dead.c, line 45.

	 [Inferior 1 (process 2138459) exited normally]
	 (gdb) FAIL: gdb.threads/current-lwp-dead.exp: continue to breakpoint: fn_return (the program exited)

	The inferior exit reported is actually correct.  The main thread has
	indeed exited, and that's the thread that has the right exit code to
	report to the user, as that's the exit code that is reported to the
	program's parent.  In this case, GDB managed to collect the exit code
	for the leader thread before reaping the other thread, because in
	reality, the testcase isn't creating standard threads, it is using raw
	clone, and the new clones are put in their own thread group.

	Fix it by making the main "thread" not exit until the scenario we're
	exercising plays out.  Also, run the program to completion for
	completeness.

	The original program really wanted the leader thread to exit before
	the fn_return function was reached -- it was important that the
	current thread as pointed by inferior_ptid was gone when infrun got
	the breakpoint event.  I've tweaked the testcase to ensure that that
	condition is still held, though it is no longer the main thread that
	exits.  This required a bit of synchronization between the threads,
	which required using CLONE_VM unconditionally.  The #ifdef guards were
	added as a fix for
	https://sourceware.org/bugzilla/show_bug.cgi?id=11214, though I don't
	think they were necessary because the program is not using TLS.  If it
	turns out they were necessary, we can link the testcase with "-z now"
	instead, which was mentioned as an alternative workaround in that
	Bugzilla.

	 (gdb) FAIL: gdb.threads/clone-new-thread-event.exp: catch SIGUSR1 (the program exited)

	This is a testcase race -- the main thread does not wait for the
	spawned clone "thread" to finish before exiting, so the main program
	may exit before the second thread is scheduled and reports its
	SIGUSR1.  With the change to make GDB report the EXIT for the leader,
	the race is 100% reproducible by adding a sleep(), like so:

	This caused problems for frontends that provide access to CLI because UI
	may silently change the context for CLI commands (as demonstrated above).

	This commit fixes the problem by restoring thread and frame in
	mi_cmd_execute (). With this change, there are only two GDB/MI commands
	that can change user selected context: -thread-select and -stack-select-frame.
	This allows us to remove all and rather complicated logic of notifying
	about user selected context change from mi_execute_command (), leaving it
	to these two commands themselves to notify.

	gdb/testsuite: add new test for comparing char types in Python
	There's an interesting property of the 'char' type in C and C++, the
	three types 'char', 'unsigned char', and 'signed char', are all
	considered distinct.

	In contrast, and 'int' is signed by default, and so 'int' and 'signed
	int' are considered the same type.

	This commit adds a test to ensure that this edge case is visible to a
	user from Python.

	It is worth noting that for any particular compiler implementation (or
	the flags a compiler was invoked with), a 'char' will be either signed
	or unsigned; it has to be one or the other, and a user can access this
	information by using the Type.is_signed property.  However, for
	something like function overload resolution, the 'char' type is
	considered distinct from the signed and unsigned variants.

	There's no change to GDB with this commit, this is just adding a new
	test to guard some existing functionality.

2022-03-07  Andrew Burgess  <aburgess@redhat.com>

	gdb/python: add Type.is_signed property
	Add a new read-only property, Type.is_signed, which is True for signed
	types, and False otherwise.

	This property should only be read on types for which Type.is_scalar is
	true, attempting to read this property for non-scalar types will raise
	a ValueError.

	I chose 'is_signed' rather than 'is_unsigned' in order to match the
	existing Architecture.integer_type method, which takes a 'signed'
	parameter.  As far as I could find, that was the only existing
	signed/unsigned selector in the Python API, so it seemed reasonable to
	stay consistent.

	gdb/mi: add --no-connection to MI -add-inferior command
	Following on from the previous commit, where the -add-inferior command
	now uses the same connection as the current inferior, this commit adds
	a --no-connection option to -add-inferior.

	This new option matches the existing option of the same name for the
	CLI version of add-inferior; the new inferior is created with no
	connection.

	I've added a new 'connection' field to the MI output of -add-inferior,
	which includes the connection number and short name.  I haven't
	included the longer description field, this is the MI after all.  My
	expectation would be that if the frontend wanted to display all the
	connection details then this would be looked up from 'info
	connection' (or the MI equivalent if/when such a command is added).

	The existing -add-inferior tests are updated, as are the docs.

	gdb/mi: fix regression in mi -add-inferior command
	Prior to the multi-target support commit:

	  commit 5b6d1e4fa4fc6827c7b3f0e99ff120dfa14d65d2
	  Date:   Fri Jan 10 20:06:08 2020 +0000

	      Multi-target support

	When a new inferior was added using the MI -add-inferior command, the
	new inferior would be using the same target as all the other
	inferiors.  This makes sense, GDB only supported a single target stack
	at a time.

	After the above commit, each inferior has its own target stack.

	To maintain backward compatibility, for the CLI add-inferior command,
	when a new inferior is added the above commit has the new inferior
	inherit a copy of the target stack from the current inferior.

	Unfortunately, this same backward compatibility is missing for the MI.

	This commit fixes this oversight.

	Now, when the -add-inferior MI command is used, the new inferior will
	inherit a copy of the target stack from the current inferior.

	Deprecate dbx mode
	GDB has a dbx emulation mode that adds a few aliases and helper

	deprecating it for GDB 12, and then removing it in GDB 13.

	Fix bug in ada_print_floating
	ada_print_floating rewrites a floating-point string representation to
	conform to Ada syntax.  However, if you managed to get a floating
	point error, you might see:

	    (gdb) print whatever
	    $2 = <invalid float valu.0e>

	What's happening here is that ada_print_floating doesn't recognize
	this error case, and proceeds to modify the error text.

	This patch fixes this problem.

2022-03-07  Tom Tromey  <tromey@adacore.com>

	Implement real literal extension for Ada
	Sometimes it is convenient to be able to specify the exact bits of a
	floating-point literal.  For example, you may want to set a
	floating-point register to a denormalized value, or to a particular
	NaN.

	In C, you can do this by combining the "{}" cast with an array
	literal, like:

	    (gdb) p {double}{0x576488BDD2AE9FFE}
	    $1 = 9.8765449999999996e+112

	This patch adds a somewhat similar idea to Ada.  It extends the lexer
	to allow "l" and "f" suffixes in a based literal.  The "f" indicates a
	floating-point literal, and the "l"s control the size of the
	floating-point type.

	Note that this differs from Ada's based real literals.  I believe
	those can also be used to control the bits of a floating-point value,
	but they are a bit more cumbersome to use (simplest is binary but
	that's also very lengthy).  Also, these aren't implemented in GDB.

	I chose not to allow this extension to work with based integer
	literals with exponents.  That didn't seem very useful.

2022-03-07  Tom Tromey  <tromey@adacore.com>

	Fix Ada integer literals with exponents
	While working on another patch, I noticed that Ada integer literals
	with exponents did not work.  For example, with one form you get an
	error:

	    (gdb) print 8e2
	    Invalid digit `e' in based literal

	And with another form you get an incorrect value:

	    (gdb) print 16#8#e2
	    $2 = 8

	This patch fixes the bugs and adds tests.

	Fix gdb.ada/arrayptr.exp results
	PR ada/28115 points out that gdb.ada/arrayptr.exp works with GNAT 12,
	but fails with minimal encodings in earlier versions.

	This patch updates the test to try to report the results correctly.  I
	tried this with the Fedora 34 system gcc (GCC 11) and with a GCC 12
	built from git trunk sometime relatively recently.

	Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28115

2022-03-07  Tom Tromey  <tromey@adacore.com>

	Handle non-ASCII identifiers in Ada
	Ada allows non-ASCII identifiers, and GNAT supports several such
	encodings.  This patch adds the corresponding support to gdb.

	GNAT encodes non-ASCII characters using special symbol names.

	For character sets like Latin-1, where all characters are a single
	byte, it uses a "U" followed by the hex for the character.  So, for
	example, thorn would be encoded as "Ufe" (0xFE being lower case
	thorn).

	For wider characters, despite what the manual says (it claims
	Shift-JIS and EUC can be used), in practice recent versions only
	support Unicode.  Here, characters in the base plane are represented
	using "Wxxxx" and characters outside the base plane using
	"WWxxxxxxxx".

	GNAT has some further quirks here.  Ada is case-insensitive, and GNAT
	emits symbols that have been case-folded.  For characters in ASCII,
	and for all characters in non-Unicode character sets, lower case is
	used.  For Unicode, however, characters that fit in a single byte are
	converted to lower case, but all others are converted to upper case.

	Furthermore, there is a bug in GNAT where two symbols that differ only
	in the case of "Y WITH DIAERESIS" (and potentially others, I did not
	check exhaustively) can be used in one program.  I chose to omit
	handling this case from gdb, on the theory that it is hard to figure
	out the logic, and anyway if the bug is ever fixed, we'll regret
	having a heuristic.

	This patch introduces a new "ada source-charset" setting.  It defaults
	to Latin-1, as that is GNAT's default.  This setting controls how "U"
	characters are decoded -- W/WW are always handled as UTF-32.

	The ada_tag_name_from_tsd change is needed because this function will
	read memory from the inferior and interpret it -- and this caused an
	encoding failure on PPC when running a test that tries to read
	uninitialized memory.

	This patch implements its own UTF-32-based case folder.  This avoids
	host platform quirks, and is relatively simple.  A short Python
	program to generate the case-folding table is included.  It simply
	relies on whatever version of Unicode is used by the host Python,
	which seems basically acceptable.

	Test cases for UTF-8, Latin-1, and Latin-3 are included.  This
	exercises most of the new code paths, aside from Y WITH DIAERESIS as
	noted above.

2022-03-07  Tom Tromey  <tromey@adacore.com>

	Define HOST_UTF32 in charset.h
	rust-parse.c has a #define for the host-specific UTF-32 charset name.
	A later patch needs the same thing, so this patch moves the definition
	to charset.h for easier reuse.

	Let phex and phex_nz handle sizeof_l==1
	Currently, neither phex nor phex_nz handle sizeof_l==1 -- they let
	this case fall through to the default case.  However, a subsequent
	patch in this series needs this case to work correctly.

	I looked at all calls to these functions that pass a 1 for the
	sizeof_l parameter.  The only such case seems to be correct with this
	change.

2022-03-07  Tom Tromey  <tromey@adacore.com>

	Don't pre-size result string in ada_decode
	Currently, ada_decode pre-sizes the output string, filling it with 'X'
	characters.  However, it's a bit simpler and more flexible to let
	std::string do the work here, and simply append characters to the
	string as we go.  This turns out to be useful for a subsequent patch.

	Simplify a regular expression in ada-lex.l
	ada-lex.l uses "%option case-insensitive", so there is no need for
	regular expressions to match upper case.

	MIPS/opcodes: Fix alias annotation for branch instructions
	Correct issues with INSN2_ALIAS annotation for branch instructions:

	- regular MIPS BEQZ/L and BNEZ/L assembly instructions are idioms for
	  BEQ/L and BNE/L respectively with the `rs' operand equal to $0,

	- microMIPS 32-bit BEQZ and BNEZ assembly instructions are idioms for
	  BEQ and BNE respectively with the `rt' operand equal to $0,

	- regular MIPS BAL assembly instruction is an idiom for architecture
	  levels of up to the MIPSr5 ISA and a machine instruction on its own
	  from the MIPSr6 ISA up.

	Add missing annotation to BEQZ/L and BNEZ/L accordingly then and add a
	new entry for BAL for the MIPSr6 ISA, correcting a disassembly bug:

	$ mips-linux-gnu-objdump -m mips:isa64r6 -M no-aliases -d bal.o

	Use function view when iterating over block symbols
	This changes iterate_over_block_local_vars and

	gdb: constify parameter of value_copy
	In a following patch, I have a const value I want to copy using a
	value_copy.  However, value_copy takes a non-const source value, at the
	moment.  Change the paramter to be const,

	If the source value is not lazy, we currently call
	value_contents_all_raw, which calls allocate_value_contents, to get a
	view on the contents.  They both take a non-const value, that's a
	problem.  My first attempt at solving it was to add a const version of
	value_contents_all_raw, make allocate_value_contents take a const value,
	and either:

	 - make value::contents mutable
	 - make allocate_value_contents cast away the const

	The idea being that allocating the value contents buffer does modify the
	value at the bit level, but logically that doesn't change its state.

	That was getting a bit complicated, so what I ended up doing is make
	value_copy not call value_contents_all_raw.  We know at this point that
	the value is not lazy, so value::contents must have been allocate
	already.

	Rewrite make-target-delegates in Python
	I think gdb is probably better off having fewer languages involved
	when generating code.  'sh' is unavoidable for build-time generation,
	but for other things, let's use Python.

	This rewrites make-target-delegates in Python.  I've stuck pretty
	closely to the original code in this rewrite, so it may look slightly
	weird from a Python perspective.

	The only output difference is that a copyright header is now
	generated, using the code introduced in the previous patch.

	make-target-delegates.py is simpler to invoke, as it knows the correct
	input file to scan and it creates the output file itself.

	in a future patch.

	This involved minor changes to the output of gdbarch.py.  Also, I've
	updated copyright.py to remove the reference to gdbarch.sh.  We don't
	need to mention gdbarch.py there, either.

	Most of the breakage comes from other projects in the tree, but we can

	Note that the yacc output files, like c-exp.c, are left alone.  In a
	source distribution, these are included in the tarball, and if the
	user builds in-tree, we would not want to remove them.

	While that seems a bit obscure, it seems to me that "distclean" is

	gdb: testsuite: fix wrong expected result in attach-pie-noexec.exp
	If /proc/sys/kernel/yama/ptrace_scope is 1, when execute the test case
	gdb.base/attach-pie-noexec.exp without superuser, the gdb.log shows the
	following info:

	  (gdb) attach 6500
	  Attaching to process 6500
	  ptrace: Operation not permitted.
	  (gdb) PASS: gdb.base/attach-pie-noexec.exp: attach

	It is obviously wrong, the expected result should be UNSUPPORTED in such
	a case.

	It is better to make can_spawn_for_attach to return false for this case.
	It would have to setup a small test program, compile it to exec, spawn it
	and try to attach to it.

	With this patch, we can see "Operation not permitted" in the log info,
	and then we can do the following processes to test:
	(1) set ptrace_scope as 0
	    $ echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
	    $ make check-gdb TESTS="gdb.base/attach-pie-noexec.exp"
	(2) use sudo

	Fix "spawn id XYZ not open" errors in gdb.mi/mi-exec-run.exp
	Running mi-exec-run.exp on native-extended-gdbserver/-m{32,64}
	causes several Tcl errors to appear. For example,

	(gdb)
	ERROR: : spawn id exp20 not open
	    while executing
	"expect {
	-i exp11 -timeout 10
	                -i "$inferior_spawn_id"
	                -re ".*Cannot exec.*Permission denied" {
	                    set saw_perm_error 1
	                    verbose -log "saw..."
	    ("uplevel" body line 1)
	    invoked from within
	"uplevel $body" NONE : spawn id exp20 not open
	UNRESOLVED: gdb.mi/mi-exec-run.exp: inferior-tty=separate: mi=separate: force-fail=1: run failure detected (eof)

	This is happening because of the way this test is implemented:

	        while {1} {
	            gdb_expect {
	                -i "$inferior_spawn_id"
	                -re ".*Cannot exec.*Permission denied" {
	                    set saw_perm_error 1
	                    verbose -log "saw mi error"
	                }
	                -i "$gdb_spawn_id"
	                -re "\\^error,msg=\"During startup program exited with code 127" {
	                    set saw_mi_error 1
	                    verbose -log "saw mi error"
	                }
	               # and so on
	            }
	        }

	The first time this loop is executed, `inferior_spawn_id' is valid. When the
	first branch of the expect statement is reached, gdbserver has exited, closing
	the spawn_id.  Since we haven't seen the gdb-side error yet, the loop is executed
	again.  The first branch now refers to a non-existent spawn_id, leading to the error.

	This can be fixed by using exp_continue to loop in expect instead of looping around
	expect, which is the approach I have used[1].  Note I've had to update the expected
	message for the "During startup..." error message when running with gdbserver.

	One other small change I've made is to add a log entry which spills the values of
	the two variables, saw_mi_error and saw_perm_error (and updated the log output
	for the later).  This should make the log output clearer about why the test failed.

	With this patch installed, all the ERRORs disappear, leaving previously masked
	FAILs (which I have not attempted to fix).

	[1] Anyone know why this test doesn't simply use gdb_test_multiple? I can only
	assume that it was intentionally written this way, and I've modified the code with
	that assumption. I have tested a version using gdb_test_multiple, and that appears
	to work fine, too, if that is preferred. [It still employs exp_continue to fix the
	spawn_id errors.]

	../../binutils-gdb/gdb/python/py-infthread.c:102:30: warning: ‘extra_info’ may be used uninitialized in this function [-Wmaybe-uninitialized]

	I think this happens because GDB_PY_HANDLE_EXCEPTION expands to an
	'if' whose condition is always true -- but GCC can't know this.  This
	patch avoids the warning by adding a harmless initialization.

	Handle multi-byte bracket sequences in Ada lexer
	As noted in an earlier patch, the Ada lexer does not handle multi-byte
	bracket sequences.  This patch adds support for these for character
	literals.  gdb does not generally seem to handle the Ada wide string
	types, so for the time being these continue to be excluded -- but an
	explicit error is added to make this more clear.

2022-02-28  Tom Tromey  <tromey@adacore.com>

	Handle 'QWW' encoding case in Ada enums
	In Ada, an enum can contain character literals.  GNAT encodes these
	values in a special way.  For example, the Unicode character U+0178
	would be represented as 'QW0178' in the DWARF:

	 <3><112f>: Abbrev Number: 2 (DW_TAG_enumerator)
	    <1130>   DW_AT_name        : (indirect string, offset: 0x19ff): QW0178
	    <1134>   DW_AT_const_value : 2

	gdb handles this reasonably well, but failed to handle the 'QWW'
	encoding, which is used for characters outside the base plane.

	Also, while working on this, I noticed that gdb will print the decimal
	value for an enum character constant:

	    (gdb) print Char_X
	    $2 = 1 'x'

	This is a nice feature, IMO, because in this situation the 'x' enum
	constant does not have its usual decimal value -- it has the value
	that's assigned based on the enumeration type.

	However, gdb did not do this when it decided to print the constant
	using the bracket notation:

	    (gdb) print Char_Thorn
	    $3 = ["de"]

	This patch changes gdb to print the decimal value here as well, and to
	put the bracket notation in single quotes -- otherwise gdb will be
	printing something that it can't then read.  Now it looks like:

	    (gdb) print Char_Thorn
	    $3 = 4 '["de"]'

	Note that gdb can't read longer bracket notations, like the other ones
	printed in this test case:

	    (gdb) print Char_King
	    $4 = 3 '["01fa00"]'

	While I think this is a bug, I plan to fix it separately.

	Finally, in the new test case, the copyright dates are chosen this way
	because this all started as a copy of an existing test.

	gdb/python: Add gdb.InferiorThread.details attribute
	This adds a new read-only attribute gdb.InferiorThread.details, this
	attribute contains a string, the results of target_extra_thread_info
	for the thread, or None, if target_extra_thread_info returns nullptr.

	As the string returned by target_extra_thread_info is unstructured,
	this attribute is only really useful for echoing straight through to
	the user, but, if a user wants to write a command that displays the
	same, or a similar 'Thread Id' to the one seen in 'info threads', then
	they need access to this string.

	Given that the string produced by target_extra_thread_info varies by
	target, there's only minimal testing of this attribute, I check that
	the attribute can be accessed, and that the return value is either
	None, or a string.

	Error when gdb_is_target_1 is called without running gdb instance
	This is a snafu that I encountered while implementing the previous

	cannot be called without gdb already running.

	This patch adds appropriate warning comments to these procs and
	causes gdb_is_target_1 to issue a Tcl error if it is called without a
	gdb instance already running.  This should prevent unwitting callers
	from using this at the wrong time.

	gdb: add operator+= and operator+ overload for std::string
	This commit adds operator+= and operator+ overloads for adding
	gdb::unique_xmalloc_ptr<char> to a std::string.  I could only find 3
	places in GDB where this was useful right now, and these all make use
	of operator+=.

	I've also added a self test for gdb::unique_xmalloc_ptr<char>, which
	makes use of both operator+= and operator+, so they are both getting
	used/tested.

	There should be no user visible changes after this commit, except when
	running 'maint selftest', where the new self test is visible.

	Print MI prompt on interrupted command
	Joel noticed that if the remote dies unexpectedly during a command --
	you can simulate this by using "continue" and then killing gdbserver
	-- then the CLI will print a new prompt, but MI will not.  Later, we
	found out that this was also filed in bugzilla as PR mi/23820.

	The output looks something like this:

	    | (gdb)
	    | cont
	    | &"cont\n"
	    | ~"Continuing.\n"
	    | ^running
	    | *running,thread-id="all"
	    | (gdb)
	    | [... some output from GDB during program startup...]
	    | =thread-exited,id="1",group-id="i1"
	    | =thread-group-exited,id="i1"
	    | &"Remote connection closed\n"

	Now, what about that "(gdb)" in the middle?

	That prompt comes from this questionable code in
	mi-interp.c:mi_on_resume_1:

	      /* This is what gdb used to do historically -- printing prompt
		 even if it cannot actually accept any input.  This will be
		 surely removed for MI3, and may be removed even earlier.  */
	      if (current_ui->prompt_state == PROMPT_BLOCKED)
		fputs_unfiltered ("(gdb) \n", mi->raw_stdout);

	... which seems like something to remove.  But maybe the intent here
	is that this prompt is sufficient, and MI clients must be ready to
	handle output coming after a prompt.  On the other hand, if this code
	*is* removed, then nothing would print a prompt in this scenario.

	Anyway, the CLI and the TUI handle emitting the prompt here by hooking
	into gdb::observers::command_error, but MI doesn't install an observer
	here.

	This patch adds the missing observer and arranges to show the MI
	prompt.  Regression tested on x86-64 Fedora 34.

	It seems like this area could be improved a bit, by having
	start_event_loop call the prompt-displaying code directly, rather than
	indirecting through an observer.  However, I haven't done this.

	Support template lookups in strncmp_iw_with_mode
	This patch adds support for wild template parameter list matches, similar
	to how ABI tags or function overloads are now handled.

	With this patch, users will be able to "gloss over" the details of matching
	template parameter lists.  This is accomplished by adding (yet more) logic
	to strncmp_iw_with_mode to skip parameter lists if none is explicitly given
	by the user.

	Here's a simple example using gdb.linespec/cpls-ops.exp:

	Similar to how scope lookups work, passing "-qualified" to the break command
	will cause a literal lookup of the symbol.  In the example immediately above,
	this will cause GDB to only find the three non-template functions.

	Revert "do_target_wait_1: Clear TARGET_WNOHANG if the target isn't async."
	Commit 14b3360508b1 ("do_target_wait_1: Clear
	TARGET_WNOHANG if the target isn't async.") broke some multi-target
	tests, such as gdb.multi/multi-target-info-inferiors.exp.  The symptom
	is that execution just hangs at some point.  What happens is:

	1. One remote inferior is started, and now sits stopped at a breakpoint.
	   It is not "async" at this point (but it "can async").

	2. We run a native inferior, the event loop gets woken up by the native
	   target's fd.

	3. In do_target_wait, we randomly choose an inferior to call target_wait
	   on first, it happens to be the remote inferior.

	4. Because the target is currently not "async", we clear
	   TARGET_WNOHANG, resulting in synchronous wait.  We therefore block
	   here:

	Before the aforementioned commit, we would not have cleared

	After applying this revert, the testsuite state looks as good as before

	gdb/darwin: skip over WIFSTOPPED wait4 status
	On modern Darwin's, there appears to be a new circumstance in which a

	previously accounted for: to signal the WIFSTOPPED condition in the
	debuggee. In that case the debuggee is not dead yet (and in fact,
	counting it as dead would cause a zombie leak - A process in such a
	state reparents to PID 1, but cannot be killed).

	 - Read and ignore such messages (counting on the next exception message
	   to let us know of the inferior's new state again)
	 - Refactor logging so as to clearly distinguish between the
	   MACH_NOTIFY_DEAD_NAME cases (WIFEXITED, WIFSTOPPED, signal, or
	   something else), and warn in the last case

	gdb/linux-tdep: move "Perms" column right
	Commit 29ef4c0699e1 ("gdb/linux-tdep.c: Add Perms to the 'info proc
	mappings' output") has broken test gdb.base/info-proc.exp on Linux,
	because it changes the output of "info proc mappings" in a way that the
	test does not expect (my bad for not testing before pushing).

	I looked at how FreeBSD handles this, since I remembered it did show
	permission flags.  It looks like this:

	          Start Addr           End Addr       Size     Offset   Flags   File
	            0x200000           0x243000    0x43000        0x0  r-- CN-- /usr/local/bin/tmux

	(I think that `Flags` and the flags not being aligned is not
	intentional)

	The test passes on FreeBSD, because the test looks for four hex numbers
	in a row and ignores the rest:

	    ".*Mapped address spaces:.*${hex}${ws}${hex}${ws}${hex}${ws}${hex}.*"

	I suggest fixing it on Linux by moving the flags column to the same
	place as in the FreeBSD output.  It makes things a bit more consistent
	between OSes, and we don't have to touch the test.

	At the same time, make use of the actual length of the permission's
	string to specify the number of characters to print.

	Before this patch, the output looks like:

	          Start Addr           End Addr   Perms       Size     Offset objfile
	      0x55dd4b544000     0x55dd4b546000   r--p      0x2000        0x0 /usr/bin/sleep

	and after, it looks like:

	          Start Addr           End Addr       Size     Offset  Perms  objfile
	      0x5622ae662000     0x5622ae664000     0x2000        0x0  r--p   /usr/bin/sleep

	Fix bug in C++ overload resolution
	PR c++/28901 points out a bug in C++ overload resolution.  When

	Instead, a valid-but-not-apparently-quite-as-good overload should be

	NEWS: Note that the FreeBSD async target supports async mode.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	inf-ptrace: Add an event_pipe to be used for async mode in subclasses.
	Subclasses of inf_ptrace_target have to opt-in to using the event_pipe
	by implementing the can_async_p and async methods.  For subclasses
	which do this, inf_ptrace_target provides is_async_p, async_wait_fd
	and closes the pipe in the close target method.

	inf_ptrace_target also provides wrapper routines around the event pipe
	(async_file_open, async_file_close, async_file_flush, and
	async_file_mark) for use in target methods such as async.
	inf_ptrace_target also exports a static async_file_mark_if_open
	function which can be used in SIGCHLD signal handlers.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	Enable async mode in the target in attach_cmd.
	If the attach target supports async mode, enable it after the
	attach target's ::attach method returns.

	fbsd-nat: Return nullptr rather than failing ::thread_name.
	ptrace on FreeBSD cannot be used against running processes and instead
	fails with EBUSY.  This meant that 'info threads' would fail if any of
	the threads were running (for example when using schedule-multiple=on
	in gdb.base/fork-running-state.exp).  Instead of throwing errors, just
	return nullptr as no thread name is better than causing info threads to
	fail completely.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	fbsd-nat: Various cleanups to the ::resume entry debug message.
	Move the message from 'show debug fbsd-lwp' to 'show debug fbsd-nat'
	since it is helpful for debugging async target support and not just
	LWP support.

	Use target_pid_to_str to format the ptid and log the step and signo
	arguments.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	fbsd-nat: Include ptrace operation in error messages.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	fbsd-nat: Implement async target support.
	This is a fairly simple version of async target support.

	Synchronous mode still uses blocking waitpid() calls in
	inf_ptrace::wait() unlike the Linux native target which always uses
	WNOHANG and uses sigsuspend() for synchronous operation.

	Asynchronous mode registers an event pipe with the core as a file
	handle and writes to the pipe when SIGCHLD is raised.  TARGET_WNOHANG
	is handled by inf_ptrace::wait().

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	inf-ptrace: Support async targets in inf_ptrace_target::wait.
	- Handle TARGET_WNOHANG by passing WNOHANG to waitpid and returning
	  TARGET_WAITKIND_IGNORE if there are no events to report.

	- Handle a race in async mode where SIGCHLD might signal the event
	  pipe for an event that has already been reported.  If the event was
	  the exit of the last child process, waitpid() will fail with ECHILD
	  rather than returning a pid of 0.  For this case, return
	  TARGET_WAITKIND_NO_RESUMED.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	inf-ptrace: Return an IGNORE event if waitpid() fails.
	Previously this returned a TARGET_WAITKIND_SIGNALLED event for
	inferior_ptid.  However, inferior_ptid is invalid during ::wait()
	methods after the multi-target changes, so this was triggering an
	assertion further up the stack.

	do_target_wait_1: Clear TARGET_WNOHANG if the target isn't async.
	Previously, TARGET_WNOHANG was cleared if a target supported async
	mode even if async mode wasn't currently enabled.  This change only
	permits TARGET_WNOHANG if async mode is enabled.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	Don't enable async mode at the end of target ::resume methods.
	Now that target_resume always enables async mode after target::resume
	returns, these calls are redundant.

	The other place that target resume methods are invoked outside of
	target_resume are as the beneath target in record_full_wait_1.  In
	this case, async mode should already be enabled when supported by the
	target before the resume method is invoked due to the following:

	  In general, targets which support async mode run as async until
	  ::wait returns TARGET_WAITKIND_NO_RESUMED to indicate that there are
	  no unwaited for children (either they have exited or are stopped).
	  When that occurs, the loop in wait_one disables async mode.  Later
	  if a stopped child is resumed, async mode is re-enabled in
	  do_target_resume before waiting for the next event.

	  In the case of record_full_wait_1, this function is invoked from the
	  ::wait target method when fetching an event.  If the underlying
	  target supports async mode, then an earlier call to do_target_resume
	  to resume the child reporting an event in the loop in
	  record_full_wait_1 would have already enabled async mode before
	  ::wait was invoked.  In addition, nothing in the code executed in
	  the loop in record_full_wait_1 disables async mode.  Async mode is
	  only disabled higher in the call stack in wait_one after ::wait
	  returns.

	  It is also true that async mode can be disabled by an
	  INF_EXEC_COMPLETE event passed to inferior_event_handle, but all of
	  the places that invoke that are in the gdb core which is "above" a
	  target ::wait method.

	Note that there is an earlier call to enable async mode in
	linux_nat_target::resume.  That call also marks the async event pipe
	to report an existing event after enabling async mode, so it needs to
	stay.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	Enable async mode on supported targets in target_resume.
	Enabling async mode above the target layer removes duplicate code in
	::resume methods of async-capable targets.  Commit 5b6d1e4fa4f
	("Multi-target support") enabled async mode in do_target_resume after
	target_resume returns which is a step in this direction.  However,
	other callers of target_resume such as target_continue do not enable
	async mode.  Rather than enabling async mode in each of the callers
	after target_resume returns, enable async mode at the end of
	target_resume.

	gdbserver linux-low: Convert linux_event_pipe to the event_pipe class.
	Use event_pipe from gdbsupport in place of the existing file
	descriptor array.

	gdb linux-nat: Convert linux_nat_event_pipe to the event_pipe class.
	Use event_pipe from gdbsupport in place of the existing file
	descriptor array.

2022-02-22  John Baldwin  <jhb@FreeBSD.org>

	gdbsupport: Add an event-pipe class.
	This pulls out the implementation of an event pipe used to implement
	target async support in both linux-low.cc (gdbserver) and linux-nat.c
	(gdb).

	This will be used to replace the existing event pipe in linux-low.cc
	and linux-nat.c in future commits.

	gdb: fix detection of compilation and linking flags for source-highlight
	Currently there are two problems with the detection of
	source-highlight via pkg-config in GDB's configure script:

	1. The LDFLAGS variable is used to pass the 'pkg-config --libs' output
	to AC_LINK_IFELSE, which results in the "-L/some/path
	-lsource-highlight" preceding the conftest.cpp, which can result in a
	failure to find symbols referenced in conftest.cpp, if the linker is
	using --as-needed by default.

	2. The CFLAGS variable is used to pass the 'pkg-config --cflags'
	output to AC_LINK_IFELSE.  However, as the current language is C++,
	AC_LINK_IFELSE will actuall use CXXFLAGS, not CFLAGS, so any flags
	returned from pkg-config will not be seen.

	This patch fixes both of these mistakes, allowing GDB to correctly
	configure and build using source-highlight installed into a custom
	prefix, e.g. ~/opt/gdb-git (because the system version of
	source-highlight is too old).

	to point to the data directory, but its default value mentioned in the
	testsuite's README was not kept up to date.

	To avoid it getting out of sync even more, point the reader to the
	definition of the variable in lib/gdb.exp, and move the explanation of
	the different flags there. Also adjust the example in the README
	so it follows the flags added in 55c3ad88013.

	gdb/testsuite: relax pattern in new gdb.mi/mi-multi-commands.exp test
	I saw some failures in the test gdb.mi/mi-multi-commands.exp that I
	added recently.  This test was added in commit:

	  commit d08cbc5d3203118da5583296e49273cf82378042
	  Date:   Wed Dec 22 12:57:44 2021 +0000

	      gdb: unbuffer all input streams when not using readline

	The failures I see only occurred when my machine was very heavily
	loaded.

	In this test I send multiple commands from dejagnu to gdb with a
	single send_gdb call.  In a well behaving world what I want to happen
	is that the gdb console sees both commands arrive and echos the text
	of those commands.  Then gdb starts processing the first command,
	prints the result, and then processes the second command, and prints
	the result.

	However, what I saw in my loaded environment was that only after
	sending the two commands, only the first command was echoed to gdb's
	terminal.  Then gdb started processing the first command, and started
	to write the output.  Now, mixed in with the first command output, the
	second command was echoed to gdb's terminal.  Finally, gdb would
	finish printing the first command output, and would read and handle
	the second command.

	This mixing of command echoing with the first command output was
	causing the test matching patterns to fail.

	In this commit I change the command I use in the test from a CLI
	command to an MI command, this reduces the number of lines of output
	that come from the test, CLI commands sent through the MI interpreter
	are echoed back like this:

	  (gdb)
	  set $a = "FIRST COMMAND"
	  &"set $a = \"FIRST COMMAND\"\n"
	  ^done
	  (gdb)

	While this is not the case for true MI command:

	  (gdb)
	  -data-evaluate-expression $a
	  ^done,value="\"FIRST COMMAND\""
	  (gdb)

	Less output makes for simpler patterns to match against.

	Next, when sending two command to gdb I was previously trying to spot
	the output of the first command followed by the prompt with nothing
	between.  This is not really needed, for the first command I can look
	for just the ^done,value="\"FIRST COMMAND\"" string, then I can start
	looking for the output of the second command.

	So long as the second pattern matches up to the gdb prompt, then I can
	be sure than nothing is left over in the expect buffer to muck up
	later matches.

	As to see the second command output gdb must have read in the second
	command, the second command output never suffers from the corruption
	that the first command output does.

	Since making this change, I've not seen a failure in this test.

	gdb: avoid nullptr access in dbxread.c from read_dbx_symtab
	This fixes a GDB crash reported in bug pr/28900, related to reading in
	some stabs debug information.

	In this commit my goal is to stop GDB crashing.  I am not trying to
	ensure that GDB makes the best possible use of the available stabs
	debug information.  At this point I consider stabs a legacy debug
	format, with only limited support in GDB.

	So, the problem appears to be that, when reading in the stabs data, we
	need to find a N_SO entry, this is the entry that defines the start of
	a compilation unit (or at least the location of a corresponding source
	file).

	It is while handling an N_SO that GDB creates a psymtab to hold the
	incoming debug information (symbols, etc).

	The problem we hit in the bug is that we encounter some symbol
	information (an N_PC entry) outside of an N_SO entry - that is we find
	some symbol information that is not associated with any source file.

	We already have some protection for this case, look (in
	read_dbx_symtab) at the handling of N_PC entries of type 'F' and 'f',
	if we have no psymtab (the pst variable is nullptr) then we issue a
	complaint.  However, for whatever reason, in both 'f' and 'F'
	handling, there is one place where we assume that the pst
	variable (the psymtab) is not nullptr.  This is a mistake.

	In this commit, I guard these two locations (in 'f' and 'F' handling)
	so we no longer assume pst is not nullptr.

	While I was at it, I audited all the other uses of pst in
	read_dbx_symtab, and in every potentially dangerous case I added a
	nullptr check, and issue a suitable complaint if pst is found to be
	nullptr.

	It might well be true that we could/should do something smarter if we
	see a debug symbol outside of an N_SO entry, and if anyone wanted to
	do that work, they're welcome too.  But this commit is just about
	preventing the nullptr access, and the subsequent GDB crash.

	I don't have any tests for this change, I have no idea how to generate
	weird stabs data for testing.  The original binary from the bug report
	now loads just fine without GDB crashing.

	gdb: Only paginate for filtered output in fputs_maybe_filtered
	A have had situation where a unfiltered output (done using
	fputs_unfiltered) ended up triggering pagination.  The backtrace for this was:

	    ...
	    #24 0x000055839377ee4e in check_async_event_handlers () at ../../gdb/async-event.c:335
	    #25 0x0000558394b67b57 in gdb_do_one_event () at ../../gdbsupport/event-loop.cc:216
	    #26 0x0000558394587454 in gdb_readline_wrapper (prompt=0x7ffd907712d0 "--Type <RET> for more, q to quit, c to continue without paging--") at ../../gdb/top.c:1148
	    #27 0x0000558394707270 in prompt_for_continue () at ../../gdb/utils.c:1438
	    #28 0x00005583947088b3 in fputs_maybe_filtered (linebuffer=0x60c0000f4000 "   [...quite big message...]", stream=0x60300028e9d0, filter=0) at ../../gdb/utils.c:1752
	    #29 0x0000558394708e57 in fputs_unfiltered (linebuffer=0x60c0000f4000 "   [...quite big message...]", stream=0x60300028e9d0) at ../../gdb/utils.c:1811
	    ...

	This comes from what appears to be a oversight in fputs_maybe_filtered.  This
	function has a FILTER parameter which if true makes the function pause after
	every screenful (i.e. triggers pagination).

	The filter parameter is correctly used to guard the first place where
	prompt_for_continue.  There is a second place in the function which can call
	prompt_for_continue, but is currently unguarded.  I believe that this is an
	oversight, this patch fixes that.

	Tested on Linux-x86_64, no regression observed.

	gdb/darwin: remove not-so-harmless spurious call to `wait4`
	As seen in https://sourceware.org/bugzilla/show_bug.cgi?id=24069 this
	code will typically wait4() a second time on the same process that was
	already wait4()'d a few lines above. While this used to be
	harmless/idempotent (when we assumed that the process already exited),
	this now causes a deadlock in the WIFSTOPPED case.

	The early (~2019) history of bug #24069 cautiously suggests to use
	WNOHANG instead of outright deleting the call. However, tests on the
	current version of Darwin (Big Sur) demonstrate that gdb runs just fine
	without a redundant call to wait4(), as would be expected.
	Notwithstanding the debatable value of conserving bug compatibility with
	an OS release that is more than a decade old, there is scant evidence of
	what that double-wait4() was supposed to achieve in the first place - A
	cursory investigation with `git blame` pinpoints commits bb00b29d7802
	and a80b95ba67e2 from the 2008-2009 era, but fails to answer the
	"why" question conclusively.

	What to do when sh_addralign isn't a power of two
	BFD generally doesn't handle anything but a power of two section
	alignment, and ELF sh_addralign is required to be an integral power of
	two (or zero) by the ELF spec.  Of course this is ignored by fuzzers,
	and because bfd_log2 rounds up, we can end up with alignment_power
	being 32 on a 32-bit object or 64 on a 64-bit object.  That then
	triggers ubsan warnings in places like bfd_update_compression_header
	where we want to convert from alignment_power back to an alignment.
	I suppose we could reject object files that have non-compliant
	sh_addralign, but I think it's also reasonable to use the greatest

	gdb: Respect the DW_CC_nocall attribute
	It is possible for a compiler to optimize a function in a such ways that
	the function does not follow the calling convention of the target.  In
	such situation, the compiler can use the DW_AT_calling_convention
	attribute with the value DW_CC_nocall to tell the debugger that it is
	unsafe to call the function.  The DWARF5 standard states, in 3.3.1.1:

	  > If the value of the calling convention attribute is the constant
	  > DW_CC_nocall, the subroutine does not obey standard calling
	  > conventions, and it may not be safe for the debugger to call this
	  > subroutine.

	Non standard calling convention can affect GDB's assumptions in multiple
	ways, including how arguments are passed to the function, how values are
	returned, and so on.  For this reason, it is unsafe for GDB to try to do
	the following operations on a function with marked with DW_CC_nocall:

	- call / print an expression requiring the function to be evaluated,
	- inspect the value a function returns using the 'finish' command,
	- force the value returned by a function using the 'return' command.

	This patch ensures that if a command which relies on GDB's knowledge of
	the target's calling convention is used on a function marked nocall, GDB
	prints an appropriate message to the user and does not proceed with the
	operation which is unreliable.

	Note that it is still possible for someone to use a vendor specific
	value for the DW_AT_calling_convention attribute for example to indicate
	the use of an alternative calling convention.  This commit does not
	prevent this, and target dependent code can be adjusted if one wanted to
	support multiple calling conventions.

	Tested on x86_64-Linux, with no regression observed.

	Calls to basename were added here as part of commit
	e1e1ae6e9b5e "sim: testsuite: fix objdir handling", but that
	commit missed adding "#include <libgen.h>" or the equivalent
	GNU extension, see basename(3).  Fixing that shows a logical
	error in the change to openpf1.c; the non-/-prefixed
	code-path was changed instead of the "/"-prefixed code-path,
	which is the one executed after that commit.

	For "newlib" these tests failed linking after that commit.
	Recent newlib has the (asm-renamed) GNU-extension-variant of
	basename, but we're better off not using it at all.

	Unfortunately, compilation failures for C tests run by the
	machinery in c.exp are currently just marked "unresolved",
	in contrast to C and assembler tests run by calling
	run_sim_test.

	The interaction of calling with the full program-path vs.
	use of --sysroot exposes a consistency problem: when
	--sysroot is used, argv[0] isn't the path by which the
	program can find itself.  It's undecided whether argv[0] for
	the program running in the simulator should be edited
	(related to the naked argument to the simulator before
	passing on to the simulated program) to remove a leading
	--sysroot.  Either way, such a change would be out of scope
	for this commit.

	in toplev/configure.ac but without the NCN_STRICT_CHECK_TARGET_TOOLS
	step, for each X to find a value for $(<X>_FOR_TARGET).  N.B.: in-tree
	tools still override any ${target}-${tool} found in $PATH, i.e. only
	previously broken builds are affected.

	The variables $(<X>_FOR_TARGET) are usually overridden by the toplevel
	Makefile to the same value or better, but has to be set here too, as
	automake "wants" Makefiles to be self-contained (you get an error
	pointing out that the variable may be empty).  If it hadn't been for
	that, SIM_AC_CHECK_TOOLCHAIN_FOR_PRIMARY_TARGET would not be needed.
	This detail should only (positively) affect users invoking "make
	check" in sim/ instead of "make check-sim" (or "make check") at the
	toplevel.  Now the output from "configure" matches the target tools
	actually used by sim at test-time, for the "primary target".

	Using $(CC) for "example-" targets CC_FOR_TARGET is not changed, as
	that appears to be a deliberate special-case.

	Note that all tools still have to be installed and present in
	$PATH at configure-time to be properly used at test-time.

	sim cris: Unbreak --disable-sim-hardware builds
	With --disable-sim-hardware (--enable-sim-hardware=no),
	whose default was changed to --enable-sim-hardware(=yes) in
	commit 34cf51120683, building for cris-elf fails as
	sim_hw_parse then doesn't exist.

	A cris-elf simulator configured for --enable-sim-hardware
	(or the default after to the mentioned commit) runs about
	2.5x slower than one configured --disable-sim-hardware.
	A further 2-5% performance regression was not investigated.

	When sim_hw_parse doesn't exist, --cris-900000xx can't be
	supported.  The best action here is to remove it completely,
	so its absence can be identified through --help, but
	avoiding littering the code with "#if WITH_HW".

	sim/testsuite: Support "requires: simoption <--name-of-option>"
	Simulator features can be present or not, typically
	depending on different-valued configure options, like
	--enable-sim-hardware[=off|=on].  To avoid failures in
	test-suite-runs when testing such configurations, a new
	predicate is needed, as neither "target", "progos" nor
	"mach" fits cleanly.

	The immediate need was to check for presence of a simulator
	option, but rather than a specialized "requires-simoption:"
	predicate I thought I'd handle the general (parametrized)
	need, so here's a generic predicate machinery and a (first)
	predicate to use together with it; checking whether a
	particular option is supported, by looking at "run --help"
	output.  This was inspired by the check_effective_target_
	machinery in the gcc test-suite.

	sim/testsuite/cris/c: Use -sim3 but only for newlib targets
	Commit a39487c6685f "sim: cris: use -sim with C tests for cris-elf
	targets" caused " -sim" to be appended to CFLAGS_FOR_TARGET for
	cris*-*-elf, where testing had until then relied on
	"RUNTESTFLAGS=--target_board=cris-sim" being passed when running "make
	check-sim", adding the right options.  While "-sim" happens to work,
	the baseboard-file cris-sim.exp uses "-sim3" so for consistency use
	that instead.

	Then commit b42f20d2ac72 "sim: testsuite: drop most specific istarget
	checks" caused " -sim" to be appended for *all* targets, which just
	doesn't work.  For example, for crisv32-linux-gnu, that's not a
	recognized option and will cause a dejagnu error and further testing
	in c.exp will be aborted.

	While cris-sim.exp appends "-static" for *-linux-gnu, further changes
	in the test-suite have caused "linux"-specific tests to break, so that
	part will be tended to separately.

	But, save and restore CFLAGS_FOR_TARGET around the modification and

	sim/testsuite: Set global_cc_os also when no compiler is found
	If we don't set this variable, it doesn't exist, and using "#progos:"
	in an assembler-file will cause an error rather than just skipping the

	    (procedure "run_sim_test" line 102)

	Neither the commit introducing progos, nor the top comment
	in run_sim_test, mentions progos as intended only for C
	tests, or that its use must be gated on $global_cc_works !=
	0, so (not) setting it in the no-working-compiler path seems
	just overlooked.

	Allowing it to be used for assembler tests makes it usable
	for e.g. an always-false predicate and in expressions in
	.exp files without gating on $global_cc_works != 0.

	With this patch, global_cc_os is set to "", just as for "unknown OS".

	sim/testsuite/cris: Assembler testcase for PRIx32 usage bug
	Several C test-cases exposed the bug, but let's have one for
	people who test using just the assembler and linker.

		* asm/endmem1.ms: New test.

2022-02-14  Hans-Peter Nilsson  <hp@axis.com>

	sim cris: Correct PRIu32 to PRIx32
	In 5ee0bc23a68f "sim: clean up bfd_vma printing" there was
	an additional introduction of PRIx32 and PRIu32 but just in
	sim/cris/sim-if.c.  One type of bug was fixed in commit
	d16ce6e4d581 "sim: cris: fix memory setup typos" but one
	remained; the PRIu32 usage is wrong, as hex output is
	desired; note the 0x prefix.

	Without this fix, you'll see output like:
	 memory map 0:0x4000..0x5fff (8192 bytes) overlaps 0:0x0..0x16383 (91012 bytes)
	 program stopped with signal 6 (Aborted).
	for some C programs, like some of the ones in the sim/cris/c
	testsuite from where the example is taken (freopen2.c).

	The bug behavior was with memory allocation.  With an
	attempt to allocate memory using the brk syscall such that
	the room up to the next 8192-byte "page boundary" wasn't
	sufficient, the simulator memory allocation machinery horked
	on a consistency error when trying to allocate a memory
	block to raise the "end of the data segment": there was
	already memory allocated at that address.

	Unfortunately, none of the programs in sim/cris/asm exposed
	this bug at the time, but an assembler test-case is
	committed after this fix.

	gdb/python: move styling support to gdb.styling
	This commit moves the two Python functions that are used for styling
	into a new module, gdb.styling, there's then a small update in
	python.c so GDB can find the functions in their new location.

	The motivation for this change is purely to try and reduce the clutter
	in the top-level gdb module, and encapsulate related functions into
	modules.  I did ponder documenting these functions as part of the
	Python API, however, doing so would effectively "fix" the API, and I'm
	still wondering if there's improvements that could be made, also, the
	colorize function is only called in some cases now that GDB prefers
	libsource-highlight, so it's not entirely sure how this would work as
	part of a user facing API.

	Still, despite these functions never having been part of a documented
	API, it is possible that a user out there has overridden these to, in
	some way, customize how GDB performs styling.  Moving the function as
	I propose in this patch could break things for that user, however,
	fixing this breakage is trivial, and, as these functions were never
	documented, I don't think we should be obliged to not break user code
	that relies on them.

	gdb: use python to colorize disassembler output
	This commit adds styling support to the disassembler output, as such
	two new commands are added to GDB:

	  set style disassembler enabled on|off
	  show style disassembler enabled

	In this commit I make use of the Python Pygments package to provide
	the styling.  I did investigate making use of libsource-highlight,
	however, I found the highlighting results to be inferior to those of
	Pygments; only some mnemonics were highlighted, and highlighting of
	register names such as r9d and r8d (on x86-64) was incorrect.

	To enable disassembler highlighting via Pygments, I've added a new
	extension language hook, which is then implemented for Python.  This
	hook is very similar to the existing hook for source code
	colorization.

	One possibly odd choice I made with the new hook is to pass a
	gdb.Architecture through, even though this is currently unused.  The
	reason this argument is not used is that, currently, styling is
	performed identically for all architectures.

	However, even though the Python function used to perform styling of
	disassembly output is not part of any documented API, I don't want
	to close the door on a user overriding this function to provide
	architecture specific styling.  To do this, the user would inevitably
	require access to the gdb.Architecture, and so I decided to add this
	field now.

	The styling is applied within gdb_disassembler::print_insn, to achieve
	this, gdb_disassembler now writes its output into a temporary buffer,
	styling is then applied to the contents of this buffer.  Finally the
	gdb_disassembler buffer is copied out to its final destination stream.

	There's a new test to check that the disassembler output includes some
	escape sequences, though I don't check for specific colours; the
	precise colors will depend on which instructions are in the
	disassembler output, and, I guess, how pygments is configured.

	The only negative change with this commit is how we currently style
	addresses in GDB.

	Currently, when the disassembler wants to print an address, we call
	back into GDB, and GDB prints the address value using the `address`
	styling, and the symbol name using `function` styling.  After this
	commit, if pygments is used, then all disassembler styling is done
	through pygments, and this include the address and symbol name parts
	of the disassembler output.

	I don't know how much of an issue this will be for people.  There's
	already some precedent for this in GDB when we look at source styling.
	For example, function names in styled source listings are not styled
	using the `function` style, but instead, either GNU Source Highlight,
	or pygments gets to decide how the function name should be styled.

	If the Python pygments library is not present then GDB will continue
	to behave as it always has, the disassembler output is mostly
	unstyled, but the address and symbols are styled using the `address`
	and `function` styles, as they are today.

	However, if the user does `set style disassembler enabled off`, then
	all disassembler styling is switched off.  This obviously covers the
	use of pygments, but also includes the minimal styling done by GDB
	when pygments is not available.

2022-02-13  Alan Modra  <amodra@gmail.com>

	PR28824, relro security issues
	Background
	==========
	There are constraints on layout of binaries to meet demand paging and
	memory protection requirements.  Demand paged binaries must have file
	offset mod pagesize equal to vma mod pagesize.  Memory protection
	(executable, read, write status) can only change at page boundaries.
	The linker's MAXPAGESIZE variable gives the page size for these layout
	constraints.

	In a typical basic executable with two memory segments, text (RE) and
	data (RW), the data segment must start on a different page to the
	last text segment page.  For example, with 64k pages and a small
	executable of 48k text and 1k data, the text segment might start at
	address 0x10000 and data at 0x20000 for a total of two 64k memory
	pages.  Demand paging would require the image on disk to be 64k+1k
	in size.  We can do better than that.  If the data segment instead
	starts at 0x2c000 (the end of the text segment plus one 64k page) then
	there are still only two memory pages, but the disk image is now
	smaller, 48k+1k in size.  This is why the linker normally starts the
	data segment at the end of the text segment plus one page.  That
	simple heuristic isn't ideal in all cases.  Changing our simple
	example to one with 64k-1 text size, following that heuristic would
	result in data starting at 0x2ffff.  Now we have two 64k memory data
	pages for a data segment of 1k!  If the data segment instead started
	at 0x30000 we'd get a single data segment page at the cost of 1 byte
	extra in the disk image, which is likely a good trade-off.  So the
	linker does adjust the simple heuristic.  Just how much disk image
	size increase is allowed is controlled by the linker's COMMONPAGESIZE
	variable.

	A PT_GNU_RELRO segment overlays the initial part of the data segment,
	saying that those pages should be made read-only after relocation by
	the dynamic loader.  Page granularity for memory protection means that
	the end of the relro segment must be at a page boundary.

	The problem
	===========
	Unfortunately most targets currently only align the end of the relro
	segment to COMMONPAGESIZE.  That results in only partial relro
	protection if an executable is running with MAXPAGESIZE pages, since
	any part of the relro segment past the last MAXPAGESIZE boundary can't
	be made read-only without also affecting sections past the end of the
	relro segment.  I believe this problem arose because x86 always runs
	with 4k (COMMPAGESIZE) memory pages, and therefore using a larger
	MAXPAGESIZE on x86 is for reasons other than the demand paging and
	memory page protection boundary requirements.

	The solution
	============
	Always end the relro segment on a MAXPAGESIZE boundary, except for
	x86.  Note that the relro segment, comprising of sections at the start
	of the data segment, is sized according to how those sections are laid
	out.  That means the start of the relro segment is fixed relative to
	its end.  Which also means the start of the data segment must be at a
	fixed address mod MAXPAGESIZE.  So for relro the linker can't play
	games with the start of the data segment to save disk space.  At
	least, not without introducing gaps between the relro sections.  In
	fact, because the linker was starting layout using its simple
	heuristic of starting the data segment at the end of the text segment
	plus one page, it was sometimes introducing page gaps for no reason.
	See pr28743.

	x86: Disallow invalid relocation against protected symbol
	I am checking this into master and will backport it to 2.38 branch.

	H.J
	----
	On x86, GCC 12 supports -mno-direct-extern-access to enable canonical
	reference to protected function and disable copy relocation.  With
	-mno-direct-extern-access, the canonical protected function symbols must
	be accessed via canonical reference and the protected data symbols in
	shared libraries are non-copyable. Under glibc 2.35, non-canonical
	reference to the canonical protected function will get the run-time error:

	./y: internal_f: ./libfoo.so: non-canonical reference to canonical protected function

	and copy relocations against the non-copyable protected symbols will get
	the run-time error:

	./x: internal_i: ./libfoo.so: copy relocation against non-copyable protected symbol

	Update x86 linker to disallow non-canonical reference to the canonical
	protected function:

	ld: plt.o: non-canonical reference to canonical protected function `internal_f' in libfoo.so
	ld: failed to set dynamic section sizes: bad value

	and copy relocation against the non-copyable protected symbol:

	gdb: fix until behavior with trailing !is_stmt lines
	When using the command "until", it is expected that GDB will exit a
	loop if the current instruction is the last one related to that loop.
	However, if there were trailing non-statement instructions, "until"
	would just behave as "next".  This was noticeable in clang-compiled
	code, but might happen with gcc-compiled as well.  PR gdb/17315 relates
	to this problem, as running gdb.base/watchpoint.exp with clang
	would fail for this reason.

	To better understand this issue, consider the following source code,
	with line numbers marked on the left:

	  10:	for (i = 0; i < 10; ++i)
	  11:     loop_body ();
	  12:   other_stuff ();

	If we transform this to pseudo-assembler, and generate a line table,
	we could end up with something like this:

	  Address | Pseudo-Assembler | Line | Is-Statement?

	  0x100   | i = 0            | 10   | Yes
	  0x104   | loop_body ()     | 11   | Yes
	  0x108   | i = i + 1        | 10   | Yes
	  0x10c   | if (i < 10):     | 10   | No
	  0x110   |     goto 0x104   | 10   | No
	  0x114   | other_stuff ()   | 12   | Yes

	Notice the two non-statement instructions at the end of the loop.

	The problem is that when we reach address 0x108 and use 'until',
	hoping to leave the loop, GDB sets up a stepping range that runs from
	the start of the function (0x100 in our example) to the end of the
	current line table entry, that is 0x10c in our example.  GDB then
	starts stepping forward.

	When 0x10c is reached GDB spots that we have left the stepping range,
	that the new location is not a statement, and that the new location is
	associated with the same source line number as the previous stepping
	range.  GDB then sets up a new stepping range that runs from 0x10c to
	0x114, and continues stepping forward.

	Within that stepping range the inferior hits the goto (at 0x110) and
	loops back to address 0x104.

	At 0x104 GDB spots that we have left the previous stepping range, that
	the new address is marked as a statement, and that the new address is
	for a different source line.  As a result, GDB stops and returns
	control to the user.  This is not what the user was expecting, they
	expected GDB to exit the loop.

	The fix proposed in this patch, is that, when the user issues the
	'until' command, and GDB sets up the initial stepping range, GDB will
	check subsequent SALs (symtab_and_lines) to see if they are
	non-statements associated with the same line number.  If they are then
	the end of the initial stepping range is extended to the end of the
	non-statement SALs.

	In our example above, the user is at 0x108 and uses 'until', GDB now
	sets up a stepping range from the start of the function 0x100 to
	0x114, the first address associated with a different line.

	Now as GDB steps around the loop it never leaves the initial stepping
	range.  It is only when GDB exits the loop that we leave the stepping
	range, and the stepping finishes at address 0x114.

	This patch also adds a test case that can be run with gcc to test that
	this functionality is not broken in the future.

	This commit updates the output of 'maint info jit' to print not just

	symfile size.

	The new information could be obtained by looking into target memory at
	the contents of the jit_code_entry, but, by storing this information
	within gdb at the time the jit object is loaded, it is now possible to
	check if the jit_code_entry has been modified in target memory behind

	Additionally, the symfile address is the same address that is now used

	gdb/linux: remove ptrace support check for exec, fork, vfork, vforkdone, clone, sysgood
	I think it's safe to remove checking support for these ptrace features,
	they have all been added in what is now ancient times (around the
	beginning of Linux 2.6).  This allows removing a bit of complexity in
	linux-nat.c and nat/linux-ptrace.c.

	It also allows saving one extra fork every time we start debugging on
	Linux: linux_check_ptrace_features forks a child process to test if some
	ptrace features are supported.  That child process forks a grand-child,
	to test whether ptrace reports an event for the fork by the child.  This
	is no longer needed, if we assume the kernel supports reporting forks.

	gdb: make thread_info::m_thread_fsm a std::unique_ptr
	While working on function calls, I realized that the thread_fsm member
	of struct thread_info is a raw pointer to a resource it owns.  This
	commit changes the type of the thread_fsm member to a std::unique_ptr in
	order to signify this ownership relationship and slightly ease resource
	management (no need to manually call delete).

	To ensure consistent use, the field is made a private member
	(m_thread_fsm).  The setter method (set_thread_fsm) can then check
	that it is incorrect to associate a FSM to a thread_info object if
	another one is already in place.  This is ensured by an assertion.

	The function run_inferior_call takes an argument as a pointer to a
	call_thread_fsm and installs it in it in a thread_info instance.  Also
	change this function's signature to accept a unique_ptr in order to
	signify that the ownership of the call_thread_fsm is transferred during
	the call.

	No user visible change expected after this commit.

	Tested on x86_64-linux with no regression observed.

	gdb: unbuffer all input streams when not using readline
	This commit should fix PR gdb/28711.  What's actually going on is
	pretty involved, and there's still a bit of the story that I don't
	understand completely, however, from my observed results, I think that
	the change I propose making here (or something very similar) is going
	to be needed.

	The original bug report involves using eclipse to drive gdb using mi
	commands.  A separate tty is spun off in which to send gdb the mi
	commands, this tty is created using the new-ui command.

	The behaviour observed is that, given a particular set of mi commands
	being sent to gdb, we sometimes see an ESPIPE error from a lseek
	call, which ultimately results in gdb terminating.

	The problems all originate from gdb_readline_no_editing_callback in
	gdb/event-top.c, where we can (sometimes) perform calls to fgetc, and
	allow glibc to perform buffering on the FILE object being used.

	I say sometime, because, gdb_readline_no_editing_callback already
	includes a call to disable the glibc buffering, but this is only done
	if the input stream is not a tty.  In our case the input stream is a
	tty, so the buffering is left in place.

	The first step to understanding why this problem occurs is to
	understand that eclipse sends multiple commands to gdb very quickly
	without waiting for and answer to each command, eclipse plans to
	collect all of the command results after sending all the commands to
	gdb.  In fact, eclipse sends the commands to gdb that they appear to
	arrive in the gdb process as a single block of data.  When reproducing
	this issue within the testsuite I find it necessary to send multiple
	commands using a single write call.

	The next bit of the story gets a little involved, and this is where my
	understanding is not complete.  I can describe the behaviour that I
	observe, and (for me at least) I'm happy that what I'm seeing, if a
	little strange, is consistent.  In order to fully understand what's
	going on I think I would likely need to dive into kernel code, which
	currently seems unnecessary given that I'm happy with the solution I'm
	proposing.

	The following description all relates to input from a tty in which I'm
	not using readline.  I see the same problems either when using a
	new-ui tty, or with gdb's standard, non-readline, mi tty.

	Here's what I observe happening when I send multiple commands to gdb
	using a single write, if I send gdb this:

	  command_1\ncommand_2\ncommand_3

	then gdb's event loop will wake up (from its select) as it sees there
	is input available.  We call into gdb_readline_no_editing_callback,
	where we call fgetc, glibc will do a single big read, and get back
	just:

	  command_1\n

	that is, despite there being multiple lines of input available, I
	consistently get just a single line.  From glibc a single character is
	returned from the fgetc call, and within gdb we accumulate characters,
	one at a time, into our own buffer.  Eventually gdb sees the '\n'
	character, and dispatches the whole 'command_1' into gdb's command
	handler, which processes the command and prints the result.  We then
	return to gdb_readline_no_editing_callback, which in turn returns to
	gdb's event loop where we re-enter the select.

	Inside the select we immediately see that there is more input waiting
	on the input stream, drop out of the select, and call back into
	gdb_readline_no_editing_callback.  In this function we again call
	fgetc where glibc performs another big read.  This time glibc gets:

	  command_2\n

	that is, we once again get just a single line, despite there being a
	third line available.  Just like the first command we copy the whole
	string, character by character into gdb's buffer, then handle the
	command.  After handling the command we go to the event loop, enter,
	and then exit the select, and call back to the function
	gdb_readline_no_editing_callback.

	In gdb_readline_no_editing_callback we again call fgetc, this time
	glibc gets the string:

	  command_3\n

	like before, we copy this to gdb's buffer and handle the command, then
	we return to the event loop.  At this point the select blocks while we
	wait for more input to arrive.

	The important bit of this is that someone, somewhere is, it appears,
	taking care to split the incoming write into lines.

	My next experiment is to try something like:

	  this_is_a_very_long_command\nshort_command\n

	However, I actually make 'this_is_a_very_long_command' very long, as
	in many hundreds of characters long.  One way to do this is:

	  echo xxxxxx.....xxxxx

	and just adding more and more 'x' characters as needed.  What I'm
	aiming for is to have the first command be longer than glibc's
	internal read buffer, which, on my machine, is 1024 characters.

	However, for this discussion, lets imagine that glibc's buffer is just
	8 characters (we can create just this situation by adding a suitable
	setbuf call into gdb_readline_no_editing_callback).

	Now, if I send gdb this data:

	  abcdefghij\nkl\n

	The first read from glibc will get 'abcdefgh', that is a full 8
	character buffer.  Once gdb has copied these to its buffer we call
	fgetc again, and now glibc will get 'ij\n', that is, just like before,
	multiple lines are split at the '\n' character.  The full command,
	which is now in gdb's buffer can be handled 'abcdefghij', after which
	we go (via the event loop) back to gdb_readline_no_editing_callback.
	Now we call fgetc, and glibc will get 'kl\n', which is then handled in
	the normal way.

	So far, so good.  However, there is, apparently, one edge case where
	the above rules don't apply.

	If the '\n' character is the first character read from the kernel,
	then the incoming lines are not split up.  So, given glibc's 8
	character buffer, if I send gdb this:

	  abcdefgh\nkl\n

	that is the first command is 8 characters plus a newline, then, on the
	first read (from within glibc) we get 'abcdefgh' in a single buffer.
	As there's no newline gdb calls fgetc again, and glibc does another
	large read, now we get:

	  \nkl\n

	which doesn't follow the above pattern - the lines are not split into
	separate buffers!

	So, gdb reads the first character from glibc using fgetc, this is the
	newline.  Now gdb has a complete command, and so the command is
	handled.  We then return to the event loop and enter the select.

	The problem is that, as far as the kernel is concerned, there is no
	more input pending, it's all been read into glibc's buffer, and so the
	select doesn't return.  The second command is basically stuck in
	glibc's buffer.

	If I send another command to gdb, or even just send an empty
	command (a lone newline) then the select returns, we call into
	gdb_readline_no_editing_callback, and now gdb sees the second
	command.

	OK, so the above is interesting, but it doesn't explain the ESPIPE
	error.

	Well, that's a slightly different, but related issue.  The ESPIPE
	case will _only_ show up when using new-ui to create the separate tty
	for mi commands, and is a consequence of this commit:

	  commit afe09f0b6311a4dd1a7e2dc6491550bb228734f8
	  Date:   Thu Jul 18 17:20:04 2019 +0100

	      Fix for using named pipes on Windows

	Prior to this commit, the new-ui command would open the tty three
	times, once each for stdin, stderr, and stdout.  After this commit we
	open the tty just once and reuse the FILE object for all three roles.

	Consider the problem case, where glibc has (unexpectedly) read the
	second command into its internal buffer.  When we handle the first
	command we usually end up having to write something to the mi output
	stream.

	After the above commit the same FILE object represents both the input
	and output streams, so, when gdb tries to write to the FILE object,
	glibc spots that there is input pending within the input buffer, and
	so assumes that we have read ahead of where we should be in the input
	file.  To correct for this glibc tries to do an lseek call to
	reposition the file offset of the output stream prior to writing to
	it.  However, as the output stream is a tty, and seeking is not
	supported on a tty, this lseek call fails, this results in the ESPIPE,
	which ultimately causes gdb to terminate.

	So, now we understand why the ESPIPE triggers (which was what caused
	the gdb crash in the original bug report), and we also understand that
	sometime gdb will not handle the second command in a timely
	fashion (if the first command is just the wrong length). So, what to
	do about all this?

	We could revert the commit mentioned above (and implement its
	functionality another way).  This would certainly resolve the ESPIPE
	issue, the buffered input would now only be on the input stream, the
	output stream would have no buffered input, and so glibc would never
	try to lseek, and so we'd never get the ESPIPE error.

	However, this only solves one of the two problems.  We would still
	suffer from the problem where, if the first command is just the wrong
	length, the second command will not (immediately) get handled.

	The only solution I can see to this problem is to unbuffer the input
	stream.  If glibc is not buffering the input, but instead, we read
	incoming data character by character from the kernel, then everything
	will be fine.  As soon as we see the newline at the end of the first
	command we will handle the first command.  As glibc will have no
	buffered input it will not be tempted to lseek, so no ESPIPE error.
	When we go have to the event loop there will be more data pending in
	the kernel, so the select will immediately return, and the second
	command will be processed.

	I'm tempted to suggest that we should move the unbuffering of the
	input stream out of gdb_readline_no_editing_callback and do it
	somewhere earlier, more like when we create the input streams.
	However, I've not done that in this commit for a couple of reasons:

	  1. By keeping the unbuffering in gdb_readline_no_editing_callback
	  I'm making the smallest possible change that fixes the bug.  Moving
	  the unbuffering somewhere better can be done as a refactor later, if
	  that 's felt to be important,

	  2. I don't think making repeated calls to unbuffer the input will
	  have that much performance impact.  We only make the unbuffer call
	  once per call to gdb_readline_no_editing_callback, and, if the input
	  stream is already unbuffered we'll return pretty quickly, so I don't
	  see this as being massively costly,

	  3. Tom is currently doing lots of gdb stream management changes and
	  I want to minimise the chances we'll conflict.

	So, this commit just changes gdb_readline_no_editing_callback to
	always unbuffer the input stream.

	The test for this issue sends two commands in a loop, with the first
	command growing bigger each time around the loop.  I actually make the
	first command bigger by just adding whitespace to the front, as gdb
	still has to read the complete command (including whitespace) via
	glibc, so this is enough to trigger the bug.

	The original bug was reported when using a virtual machine, and in
	this situation we see this in the strace output:

	  read(9, "70-var-info-path-expression var1.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", 1024) = 64
	  read(9, "\n71-var-info-path-expression var1.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\n", 1024) = 67

	I'm not completely sure what's going on here, but it appears that the
	kernel on the virtual machine is delivering the input to glibc slower
	than I see on my real hardware; glibc asks for 1024 bytes, but only
	gets 64 bytes the first time.  In the second read we see the problem
	case, the first character is the newline, but then the entire second
	command is included.

	If I run this exact example on my real hardware then the first command
	would not be truncated at 64 bytes, instead, I'd expect to see the
	newline included in the first read, with the second command split into
	a second read.

	So, for testing, I check cases where the first command is just a few
	characters (starting at 8 character), all the way up to 2048
	characters.  Hopefully, this should mean we hit the problem case for
	most machine setups.

	The only last question relates to commit afe09f0b6311a4d that I
	mentioned earlier.  That commit was intended to provide support for
	Microsoft named pipes:

	  https://docs.microsoft.com/en-us/windows/win32/ipc/named-pipes

	I know next to nothing about this topic beyond a brief scan of the
	above link, but I think these windows named pipe are closer in
	behaviour to unix sockets than to unix named fifos.

	I am a little nervous that, after the above commit, we now use the
	same FILE for in, err, and out streams.  In contrast, in a vanilla C
	program, I would expect different FILE objects for each stream.

	Still, I'm reluctant to revert the above commit (and provide the same
	functionality a different way) without a specific bug to point at,
	and, now that the streams are unbuffered, I expect a lot of the read
	and write calls are going straight to the kernel with minimal glibc
	involvement, so maybe it doesn't really matter.  Anyway, I haven't
	touched the above patch, but it is something to keep in mind when
	working in this area.

	gdb/disasm: combine the no printing disassembler setup code
	We have three places in gdb where we initialise a disassembler that
	will not print anything (used for figuring out the length of
	instructions, or collecting other information from the disassembler).

	Each of these places has its own stub function to act as a print like
	callback, the stub function is identical in each case, and just does
	nothing.

	In this commit I create a new function to initialise a disassembler
	that doesn't print anything, and have all three locations use this new
	function.  There's now only one non-printing stub function.

	There should be no user visible changes after this commit.

	gdb: add the 'set/show suppress-cli-notifications' command
	GDB already has a flag to suppress printing notification events, such
	as thread and inferior context switches, on the CLI.  This is used
	internally when executing commands.  Make the flag available to the
	user via a new command.  This is expected to be useful in scripts.

	For instance, suppose that when Inferior 1 gets to a certain state,
	you want to add and set up a new inferior using the commands below,
	but you also want to have a reduced/clean output.

	  define do-setup
	    printf "Setting up Inferior 2...\n"
	    add-inferior -exec a.out
	    inferior 2
	    break file.c:3
	    run
	    inferior 1
	    printf "Done\n"
	  end

	Currently, GDB prints

	  (gdb) do-setup
	  Setting up Inferior 2...
	  [New inferior 2]
	  Added inferior 2 on connection 1 (native)
	  [Switching to inferior 2 [<null>] (/tmp/a.out)]
	  Breakpoint 2 at 0x1155: file file.c, line 3.

	  Thread 2.1 "a.out" hit Breakpoint 2, main () at file.c:3
	  3         return 0;
	  [Switching to inferior 1 [process 7670] (/tmp/test)]
	  [Switching to thread 1.1 (process 7670)]
	  #0  main () at test.c:2
	  2         int a = 1;
	  Done

	GDB's Python API make it possible to capture and return GDB's output,
	but this does not work for all the streams.  In particular, CLI
	notification events are not captured:

	  (gdb) python gdb.execute("do-setup", False, True)
	  [Switching to inferior 2 [<null>] (/tmp/a.out)]

	  Thread 2.1 "a.out" hit Breakpoint 2, main () at file.c:3
	  3         return 0;
	  [Switching to inferior 1 [process 8263] (/tmp/test)]
	  [Switching to thread 1.1 (process 8263)]
	  #0  main () at test.c:2
	  2         int a = 1;

	You can use the new "set suppress-cli-notifications" command to
	suppress the output:

	  (gdb) set suppress-cli-notifications on
	  (gdb) do-setup
	  Setting up Inferior 2...
	  [New inferior 2]
	  Added inferior 2 on connection 1 (native)
	  Breakpoint 2 at 0x1155: file file.c, line 3.
	  Done

	Allow non-ASCII characters in Rust identifiers
	Rust 1.53 (quite a while ago now) ungated the support for non-ASCII
	identifiers.  This didn't work in gdb.  This is PR rust/20166.

	This patch fixes the problem by allowing non-ASCII characters to be
	considered as identifier components.  It seemed simplest to just pass
	them through -- doing any extra checking didn't seem worthwhile.

	The new test also verifies that such characters are allowed in strings
	and character literals as well.  The latter also required a bit of
	work in the lexer.

	function-valued field 'f' in 'obj'.  The Rust parser in gdb currently
	gets this wrong.  This is PR rust/24082.

	The expression and Rust parser rewrites made this simple to fix --
	simply wrapping a parenthesized expression in a new operation handles
	it.  This patch has a slight hack because I didn't want to introduce a
	new exp_opcode enumeration constant just for this.  IMO this doesn't
	matter, since we should work toward removing dependencies on these
	opcodes anyway; but let me know what you think of this.

	Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=24082

	gdb/doc: update docs for 'info win' and 'winheight' commands
	This started by noticing that the docs for 'winheight' are out of
	date, the docs currently give a specific list of possible window
	names.  However, now that windows can be implemented in Python, it is
	not possible to list all possible names.

	I now link the user to a mechanism by which they can discover the
	valid names for themselves at run time (by using 'info win').  That,
	and the fact that gdb provides tab-completion of the name at the
	command line, feels good enough.

	Finally, I noticed that the docs for 'win info' don't explicitly say
	that the name of the window is given in the output.  This could
	probably have been inferred, but given I'm now linking to this as a
	mechanism to find the window name, I'd prefer to mention that the name
	can be found in the output.

2022-02-06  Andrew Burgess  <aburgess@redhat.com>

	gdb/tui: add window width information to 'info win' output
	Now that we support horizontal window placement in the tui, it makes
	sense to have 'info win' include the width, as well as the height, of
	the currently visible windows.

	That's what this commit does.  Example output is now:

	  (gdb) info win
	  Name       Lines Columns Focus
	  src           12      40 (has focus)
	  asm           12      41
	  status         1      80
	  cmd           11      80

	I've added a NEWS entry, but the documentation was already suitably
	vague, it just says that 'info win' displays the size of the visible
	windows, so I don't think anything needs to be added there.

	I've also added some tests, as far as I could find, the 'info win'
	command was previously untested.

	sim: Allow toggling of quiet NaN-bit semantics
	IEEE754-1985 specifies the top bit of the mantissa as an indicator
	of signalling vs. quiet NaN, but does not define the precise semantics.
	Most architectures treat this bit as indicating quiet NaN, but legacy
	(pre-R6) MIPS goes the other way and treats it as signalling NaN.

	This used to be controlled by a macro that was only defined for MIPS.
	This patch replaces the macro with a variable to track the current
	semantics of the NaN bit and allows differentiation between older
	(pre-R6) and and newer MIPS cores.

	gdb: include jit_code_entry::symfile_addr value in names of objfiles created by jit reader API
	This commit includes the JIT object's symfile address in the names of
	objfiles created by JIT reader API (e.g., << JIT compiled code at
	0x7ffd8a0c77a0 >>).  This allows one to at least differentiate one from
	another.

	The address is the one that the debugged program has put in
	jit_code_entry::symfile_addr, and that the JIT reader's read function
	receives.  As we can see in gdb.base/jit-reader-host.c and
	gdb.base/jit-reader.c, that may not be the actual value of where the
	JIT-ed code is.  But it is a value chosen by the author of the JIT
	engine and the JIT reader, so including this value in the objfile name
	may help them correlate the JIT objfiles created by with their logs /
	data structures.

	To access this field, we need to pass down a reference to the
	jit_code_entry.  So make jit_dbg_reader_data a structure (instead of an
	alias for a CORE_ADDR) that includes the address of the code entry in
	the inferior's address space (the previous meaning of
	jit_dbg_reader_data) plus a reference to the jit_code_entry as read into
	GDB's address space.  And while at it, pass down the gdbarch, so that we
	don't have to call target_gdbarch.

	Improve Ada unchecked union type printing
	Currently, "ptype" of an Ada unchecked union may show a

	Remove host_hex_value
	I noticed that host_hex_value is redundant, because gdbsupport already
	has fromhex.  This patch removes the former in favor of the latter.

	Support symbol+offset lookup in addr2line
	The Linux kernel usually ouputs symbol+offset instead of plain code
	addresses these days, to avoid leaking ASLR secrets and to handle
	dynamically loaded modules.

	Converting those with addr2line is somewhat involved: it requires
	looking up the symbol first using nm and then manually compute the
	offset, and then pass it to addr2line.

	This patch implements the necessary steps directly in addr2line,
	by looking up the symbol (with demangling if needed) and computing
	the offset.

	It's possible that a symbol is ambigious with a hex number. In this
	case it uses the symbol lookup if the string contains a +. When it isn't
	ambigious the + is optional.

	gdb: fix formatting for help set/show extended-prompt
	The formatting of the help text for 'help set extended-prompt' and
	'help show extended-prompt' is a little off.

	Here's the offending snippet:

	    Substitutions are applied to VALUE to compute the real prompt.

	    The currently defined substitutions are:
	      \[	Begins a sequence of non-printing characters.
	  \\	A backslash.
	  \]	Ends a sequence of non-printing characters.
	  \e	The ESC character.

	Notice that the line for '\[' is indented more that the others.

	Turns out this is due to how we build this help text, something which
	is done in Python.  We extended a classes __doc__ string with some
	dynamically generated text.

	The classes doc string looks like this:

	    """Set the extended prompt.

	    Usage: set extended-prompt VALUE

	    Substitutions are applied to VALUE to compute the real prompt.

	    The currently defined substitutions are:
	    """

	Notice the closing """ are in a line of their own, and include some
	white space just before.  It's this extra white space that's causing
	the problem.

	Fix the formatting issue by moving the """ to the end of the previous
	line.  I then add the extra newline in at the point where the doc
	string is merged with the dynamically generated text.

	Now everything lines up correctly.

	gdb: test to check one aspect of the linespec parsing code
	While working on the fix for PR cli/28665 (see previous couple of
	commits), I was playing with making a change in the linespec parsing
	code.  Specifically, I was thinking about whether the spec_string for
	LINESPEC_LOCATION locations should ever be nullptr.

	I made a change to prevent the spec_string from ever being nullptr,
	tested gdb, and saw no regressions.

	However, as part of this work I was reviewing how the breakpoint code
	handles this case (spec_string being nullptr), and spotted that in
	parse_breakpoint_sals the nullptr case is specifically handled, so
	changing this should have caused a regression.  But I didn't see one.

	So, this commit adds a comment in location.c mentioning that the
	nullptr case is (a) not an oversight, and (b) is required.  Then I add
	a new test to gdb.base/break.exp that ensures a change in this area
	will cause a regression.

	This test passes on current gdb, but with my modified (and broken)
	gdb, the test would fail.

	gdb: handle calls to edit command passing only a linespec condition
	While working on the previous commit to fix PR cli/28665, I noticed
	that the 'edit' command would suffer from the same problem.  That is,
	something like:

	  (gdb) edit task 123

	would cause GDB to break.  For a full explanation of what's going on
	here, see the commit message for the previous commit.

	As with the previous commit, this issue can be prevented by detecting,
	and throwing, a junk at the end of the line error earlier, before
	calling decode_line_1.

	So, that's what this commit does.  I've also added some tests for this
	issue.

	Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28665

2022-02-02  Andrew Burgess  <aburgess@redhat.com>

	gdb: handle calls to list command passing only a linespec condition
	In PR cli/28665, it was reported that GDB would crash when given a
	command like:

	  (gdb) list task 123

	The problem here is that in cli/cli-cmd.c:list_command, the string
	'task 123' is passed to string_to_event_location in find a location
	specification.  However, this location parsing understands about
	breakpoint conditions, and so, will stop parsing when it sees
	something that looks like a condition, in this case, the 'task 123'
	looks like a breakpoint condition.

	As a result, the location we get back from string_to_event_location
	has no actual location specification attached to it.  The actual call
	path is:

	  list_command
	    string_to_event_location
	      string_to_event_location_basic
	        new_linespec_location

	In new_linespec_location we call linespec_lex_to_end, which looks at
	'task 123' and decides that there's nothing there that describes a
	location.  As such, in new_linespec_location, the spec_string field of
	the location is left as nullptr.

	Back in list_command we then call decode_line_1, which calls
	event_location_to_sals, which calls parse_linespec, which takes the
	spec_string we found earlier, and tries to converts this into a list
	of sals.

	However, parse_linespec is not intended to be passed a nullptr, for
	example, calling is_ada_operator will try to access through the
	nullptr, causing undefined behaviour.  But there are other cases
	within parse_linespec which don't expect to see a nullptr.

	When looking at how to fix this issue, I first considered having
	linespec_lex_to_end detect the problem.  That function understands
	when the first thing in the linespec is a condition keyword, and so,
	could throw an error saying something like: "no linespec before
	condition keyword", however, this is not going to work, at least, not
	without additional changes to GDB, it is valid to place a breakpoint
	like:

	  (gdb) break task 123

	This will place a breakpoint at the current location with the
	condition 'task 123', and changing linespec_lex_to_end breaks this
	behaviour.

	So, next, I considered what would happen if I added a condition to an
	otherwise valid list command, this is what I see:

	  (gdb) list file.c:1 task 123
	  Junk at end of line specification.
	  (gdb)

	So, then I wondered, could we just pull the "Junk" detection forward,
	so that we throw the error earlier, before we call decode_line_1?

	It turns out that yes we can.  Well, sort of.

	It is simpler, I think, to add a separate check into the list_command
	function, after calling string_to_event_location, but before calling
	decode_line_1.  We know when we call string_to_event_location that the
	string in question is not empty, so, after calling
	string_to_event_location, if non of the string has been consumed, then
	the content of the string must be junk - it clearly doesn't look like
	a location specification.

	I've reused the same "Junk at end of line specification." error for
	consistency, and added a few tests to cover this issue.

	While the first version of this patch was on the mailing list, a
	second bug PR gdb/28797 was raised.  This was for a very similar
	issue, but this time the problem command was:

	  (gdb) list ,,

	Here the list command understands about the first comma, list can have
	two arguments separated by a comma, and the first argument can be
	missing.  So we end up trying to parse the second command "," as a
	linespec.

	However, in linespec_lex_to_end, we will stop parsing a linespec at a
	comma, so, in the above case we end up with an empty linespec (between
	the two commas), and, like above, this results in the spec_string
	being nullptr.

	As with the previous case, I've resolved this issue by adding an extra
	check for junk at the end of the line - after parsing (or failing to
	parse) the nothing between the two commas, we still have the "," left
	at the end of the list command line - when we see this we can throw
	the same "junk at the end of the line" error, and all is good.

	I've added tests for this case too.

	gdb/testsuite: move linespec test into gdb.linespec/ directory
	The gdb.base/linespecs.exp test should really live in the gdb.linespec
	directory, so lets move it there.

	As we already have gdb.linespec/linespec.exp, I've renamed the test to
	gdb.linespec/errors.exp, as this better reflects what the test is
	actually checking.

	Finally, the test script doesn't have its own source file, it was
	reusing a random other source file, gdb.base/memattr.c.  Now the tests
	script is in gdb.linespec/, I've updated the test to use a different
	source file from that directory.

2022-02-02  Andrew Burgess  <aburgess@redhat.com>

	gdb: add empty string check in parse_linespec
	If parse_linespec (linespec.c) is passed ARG as an empty string then
	we end up calling `strchr (linespec_quote_characters, '\0')`, which
	will return a pointer to the '\0' at the end of
	linespec_quote_characters.  This then results in GDB calling
	skip_quote_char with `ARG + 1`, which is undefined behaviour (as ARG
	only contained a single character, the '\0').

	Fix this by checking for the first character of ARG being '\0' before
	the call to strchr.

	I have additionally added an assertion that ARG can't itself be
	nullptr, as calling is_ada_operator with nullptr can end up calling
	'startswith' on the nullptr, which is undefined behaviour.

	Finally, I moved the declaration of TOKEN into the body of
	parse_linespec, to where TOKEN is defined.

	This patch came about while I was working on fixes for PR cli/28665
	and PR gdb/28797.  The actual fixes for these two issues will be in a
	later commit in this series, but, with this patch in place, both of
	the above bugs would hit the new assertion rather than accessing
	invalid memory and crashing.  The '\0' check is not currently ever
	hit, but just makes the code a little safer.

	Because this patch only changes the nature of the failure for the

	gdb: update the comment on string_to_event_location
	The comment on string_to_event_location is (I believe) out of date.
	This commit fixes the two issues I see:

	  1. This function can't return NULL any more.  The implementation
	  calls string_to_explicit_location which can return NULL, but if this
	  is the case we then call string_to_event_location_basic, which I
	  don't believe can ever return NULL.

	  2. I've removed the mention that the returned string is malloc'd,
	  though this is true, now that we return a managed pointer, I believe
	  the source of the memory allocation is irrelevant, and so, shouldn't
	  be discussed in the header comment.

	There should be no user visible changes after this commit.

	or1k: Avoid R_OR1K_GOT16 signed overflow by using special howto
	Previously when fixing PR 21464 we masked out upper bits of the
	relocation value in order to avoid overflow complaints when acceptable.
	It turns out this does not work when the relocation value ends up being
	signed.

	To fix this this patch introduces a special howto with
	complain_on_overflow set to complain_overflow_dont.  This is used in
	place of the normal R_OR1K_GOT16 howto when we detect R_OR1K_GOT_AHI16
	relocations.

	Fix flex rule in gdb

	It's better for the rule to fail such that the .c file is not updated.

	gdb, testsuite, fortran: adapt info symbol expected output for intel compilers
	Info symbol is expected to print the symbol table name of a symbol, since
	symbol lookup happens via the minimal symbol table.  This name
	corresponds to the linkage name in the full symbol table.

	For gfortran (and maybe others) these names currently have the form
	XXXX.NUMBER where XXXX is the symbol name and NUMBER a compiler
	generated appendix for mangling.
	An example taken from the modified nested-funcs-2.exp would be

	~~~~
	$ objdump -t ./outputs/gdb.fortran/nested-funcs-2/nested-funcs-2 | grep \
	increment
	00000000000014ab l  F .text  0000000000000095  increment.3883
	000000000000141c l  F .text  000000000000008f  increment_program_global.3881
	~~~~

	This mangled name gets recognized by the Ada demangler/decoder and decoded as
	Ada to XXXX (setting the symbol language to Ada).  This leads to output
	of XXXX over XXXX.NUMBER for info symbol on gfortran symbols.

	For ifort and ifx the generated linkage names have the form
	SCOPEA_SCOPEB_XXXX_ which are not recognized by the Ada decoder (or any
	other demangler for that matter) and thus printed as is.
	The respective objdump in the above case looks like

	~~~~
	$ objdump -t ./outputs/gdb.fortran/nested-funcs-2/nested-funcs-2 | grep \
	increment
	0000000000403a44 l  F .text  0000000000000074  contains_keyword_IP_increment_
	0000000000403ab8 l  F .text  0000000000000070
	contains_keyword_IP_increment_program_global_
	~~~~

	In the unmodified testcase this results in 'fails' when ran with the intel
	compilers:

	~~~~
	>> make check RUNTESTFLAGS="gdb.fortran/nested-funcs-2.exp \
	GDBFLAGS='$GDBFLAGS' CC_FOR_TARGET='icpc' F90_FOR_TARGET='ifort'"

	...

	                === gdb Summary ===

	\# of expected passes            80
	\# of unexpected failures        14
	~~~~

	Note that there is no Fortran mangling standard.  We keep the gfortran
	behavior as is and modify the test to reflect ifx and ifort mangled
	names which fixes above fails.

	FreeBSD x86 nat: Use register maps for GP register sets.
	Rather than using the x86-specific register offset tables, use
	register maps to describe the layout of the general purpose registers
	fetched via PT_GETREGS.  The sole user-visible difference is that
	FreeBSD/amd64 will now report additional segment registers ($ds, $es,
	$fs, and $gs) for both 32-bit and 64-bit processes.

	As part of these changes, the FreeBSD x86 native targets no longer use
	amd64-bsd-nat.c or i386-bsd-nat.c.  Remove FreeBSD-specific register
	handling (for $fs_base, $gs_base, and XSAVE state) from these files.
	Similarly, remove the global x86bsd_xsave_len from x86-bsd-nat.c.  The
	FreeBSD x86 native targets use a static xsave_len instead.

	While here, rework the probing of PT_GETXMMREGS on FreeBSD/i386.
	Probe the ptrace op once in the target read_description method and
	cache the result for the future similar to the way the status of XSAVE
	support is probed in the read_description method.  In addition, return
	the proper xcr0 mask (X87-only) for old kernels or systems without
	either XSAVE or XMM support.

	FreeBSD x86: Use tramp-frame for signal frames.
	Use a register map to describe the registers in mcontext_t as part of
	the signal frame as is done on several other FreeBSD arches.  This
	permits fetching the fsbase and gsbase register values from the signal
	frame for both amd64 and i386 and permits fetching additional segment
	registers stored as 16-bit values on amd64.

	While signal frames on FreeBSD do contain floating point/XSAVE state,
	these unwinders do not attempt to supply those registers.  The
	existing x86 signal frame uwinders do not support these registers, and
	the only existing functions which handle FSAVE/FXSAVE/XSAVE state all
	work with regcaches.  In the future these unwinders could create a
	tempory regcache, collect floating point registers, and then supply
	values out of the regcache into the trad-frame.

2022-01-28  John Baldwin  <jhb@FreeBSD.org>

	Use register maps for gp regsets on FreeBSD/x86 core dumps.
	In particular, this permits reporting the value of the $ds, $es, $fs,
	and $gs segment registers from amd64 core dumps since they are stored
	as 16-bit values rather than the 32-bit size assumed by i386_gregset.

	regcache: Zero-extend small registers described by a register map.
	When registers are supplied via regcache_supply_register from a
	register block described by a register map, registers may be stored in
	slots smaller than GDB's native register size (e.g. x86 segment
	registers are 16 bits, but the GDB registers for those are 32-bits).
	regcache_collect_regset is careful to zero-extend slots larger than a
	register size, but regcache_supply_regset just used
	regcache::raw_supply_part and did not initialize the upper bytes of a
	register value.

	trad_frame_set_reg_regmap assumes these semantics (zero-extending
	short registers).  Upcoming patches also require these semantics for
	handling x86 segment register values stored in 16-bit slots on
	FreeBSD.  Note that architecturally x86 segment registers are 16 bits,
	but the x86 gdb architectures treat these registers as 32 bits.

	FreeBSD x86: Remove fallback for detecting signal trampolines by address.
	A few FreeBSD releases did not include the page holding the signal
	code in core dumps.  As a workaround, a sysctl was used to fetch the
	default location of the signal code instead.  The youngest affected
	FreeBSD release is 10.1 released in November 2014 and EOLed in
	December 2016.  The fallback only works for native processes and would
	require a separate unwinder once the FreeBSD arches are converted to
	use tramp_frame for signal frames.

	Remove support for pre-5.0 FreeBSD/i386 signal trampolines.
	The last relevant release (FreeBSD 4.11) was released in January of
	2005.

	Remove vestigal FreeBSD/i386 3.x support.

	PR28827, assertion building LLVM 9 on powerpc64le-linux-gnu
	The assertion is this one in ppc_build_one_stub
	  BFD_ASSERT (stub_entry->stub_offset >= stub_entry->group->stub_sec->size);
	It is checking that a stub doesn't overwrite the tail of a previous
	stub, so not something trivial.

	Normally, stub sizing iterates until no stubs are added, detected by
	no change in stub section size.  Iteration also continues if no stubs
	are added but one or more stubs increases in size, which also can be
	detected by a change in stub section size.  But there is a
	pathological case where stub section sizing decreases one iteration
	then increases the next.  To handle that situation, stub sizing also
	stops at more than STUB_SHRINK_ITER (20) iterations when calculated
	stub section size is smaller.  The previous larger size is kept for
	the actual layout (so that building the stubs, which behaves like
	another iteration of stub sizing, will see the stub section sizes
	shrink).  The problem with that stopping condition is that it assumes
	that stub sizing is only affected by addresses external to the stub
	sections, which isn't always true.

	This patch fixes that by also keeping larger individual stub_offset
	addresses past STUB_SHRINK_ITER.  It also catches a further
	pathological case where one stub shrinks and another expands in such a
	way that no stub section size change is seen.

	Since there are some binaries with this in the wild, I think it would be
	useful for GDB to work around this.  I did the obvious simple thing, if
	the DW_AT_data_member_location's value is -1, replace it with 0.  I
	added a producer check to only apply this fixup for GCC 11.  The idea is
	that if some other compiler ever uses a DW_AT_data_member_location value
	of -1 by mistake, we don't know (before analyzing the bug at least) if
	they did mean 0 or some other value.  So I wouldn't want to apply the
	fixup in that case.

	Fix GDB internal error by using text (instead of data) section offset
	Fedora Rawhide is now using gcc-12.0.  As part of updating to the
	gcc-12.0 package set, Rawhide is also now using a version of libgcc_s
	which lacks a .data section.  This causes gdb to fail in the following
	fashion while debugging a program (such as gdb) which uses libgcc_s:

	    (top-gdb) run
	    Starting program: rawhide-master/bld/gdb/gdb
	    ...
	    objfiles.h:467: internal-error: sect_index_data not initialized
	    A problem internal to GDB has been detected,
	    further debugging may prove unreliable.
	    ...

	I snipped the backtrace from the above output.  Instead, here's a
	portion of a backtrace obtained using GDB's backtrace command.
	(Obviously, in order to obtain it, I used a GDB which has been patched
	with this commit.)

	    ...

	The function 'relocate_address' in gdb/stap-probe.c attempts to do
	its "relocation" by using objfile->data_section_offset().  That
	method, data_section_offset() is defined as follows in objfiles.h:

	  CORE_ADDR data_section_offset () const
	  {
	    return section_offsets[SECT_OFF_DATA (this)];
	  }

	The internal error occurs when the SECT_OFF_DATA macro finds that the
	'sect_index_data' field is -1:

	    #define SECT_OFF_DATA(objfile) \
		 ((objfile->sect_index_data == -1) \
		  ? (internal_error (__FILE__, __LINE__, \
				     _("sect_index_data not initialized")), -1)	\
		  : objfile->sect_index_data)

	relocate_address() is obtaining the section offset in order to compute
	a relocated address.  For some ABIs, such as the System V ABI, the
	section offsets will all be the same.  So for those ABIs, it doesn't
	matter which offset is used.  However, other ABIs, such as the FDPIC
	ABI, will have different offsets for the various sections.  Thus, for
	those ABIs, it is vital that this and other relocation code use the
	correct offset.

	In stap_probe::get_relocated_address, the address to which to add the
	offset (thus forming the relocated address) is obtained via
	this->get_address (); get_address is a getter for m_address in
	probe.h.  It's documented/defined as follows (also in probe.h):

	  /* The address where the probe is inserted, relative to
	     SECT_OFF_TEXT.  */
	  CORE_ADDR m_address;

	(Thanks to Tom Tromey for this observation.)

	So, based on this, the current use of data_section_offset /
	SECT_OFF_DATA is wrong.  This relocation code should have been using
	text_section_offset / SECT_OFF_TEXT all along.  That being the
	case, I've adjusted the stap-probe.c relocation code accordingly.

	Searching the sources turned up one other use of data_section_offset,
	in gdb/dtrace-probe.c, so I've updated that code as well.  The same
	reasoning presented above applies to this case too.

	Summary:

		* gdb/dtrace-probe.c (dtrace_probe::get_relocated_address):
		Use method text_section_offset instead of data_section_offset.
		* gdb/stap-probe.c (relocate_address): Likewise.

	gdb, remote, btrace: move switch_to_thread call right before xfer call
	In remote_target::remote_btrace_maybe_reopen, we switch to the currently
	iterated thread in order to set inferior_ptid for a subsequent xfer.

	Move the switch_to_thread call directly before the target_read_stralloc
	call to clarify why we need to switch threads.

	gdb, gdbserver: update thread identifier in enable_btrace target method
	The enable_btrace target method takes a ptid_t to identify the thread on
	which tracing shall be enabled.

	Change this to thread_info * to avoid translating back and forth between
	the two.  This will be used in a subsequent patch.

	gdb, btrace: switch threads in remote_btrace_maybe_reopen()
	In remote_btrace_maybe_reopen() we iterate over threads and use
	set_general_thread() to set the thread from which to transfer the btrace
	configuration.

	This sets the remote general thread but does not affect inferior_ptid.  On
	the xfer request later on, remote_target::xfer_partial() again sets the
	remote general thread to inferior_ptid, overwriting what
	remote_btrace_maybe_reopen() had done.

	In one case, this led to inferior_ptid being null_ptid when we tried to
	enable tracing on a newly created thread inside a newly created process
	during attach.

	This, in turn, led to find_inferior_pid() asserting when we iterated over
	threads in record_btrace_is_replaying(), which was called from
	record_btrace_target::xfer_partial() when reading the btrace configuration
	of the new thread to check whether it was already being recorded.

	The bug was exposed by

	gdb/python: handle non utf-8 characters when source highlighting
	This commit adds support for source files that contain non utf-8
	characters when performing source styling using the Python pygments
	package.  This does not change the behaviour of GDB when the GNU
	Source Highlight library is used.

	For the following problem description, assume that either GDB is built
	without GNU Source Highlight support, of that this has been disabled
	using 'maintenance set gnu-source-highlight enabled off'.

	The initial problem reported was that a source file containing non
	utf-8 characters would cause GDB to print a Python exception, and then
	display the source without styling, e.g.:

	  Python Exception <class 'UnicodeDecodeError'>: 'utf-8' codec can't decode byte 0xc0 in position 142: invalid start byte
	  /* Source code here, without styling...  */

	Further, as the user steps through different source files, each time
	the problematic source file was evicted from the source cache, and
	then later reloaded, the exception would be printed again.

	Finally, this problem is only present when using Python 3, this issue
	is not present for Python 2.

	What makes this especially frustrating is that GDB can clearly print
	the source file contents, they're right there...  If we disable
	styling completely, or make use of the GNU Source Highlight library,
	then everything is fine.  So why is there an error when we try to
	apply styling using Python?

	The problem is the use of PyString_FromString (which is an alias for
	PyUnicode_FromString in Python 3), this function converts a C string
	into a either a Unicode object (Py3) or a str object (Py2).  For
	Python 2 there is no unicode encoding performed during this function
	call, but for Python 3 the input is assumed to be a uft-8 encoding
	string for the purpose of the conversion.  And here of course, is the
	problem, if the source file contains non utf-8 characters, then it
	should not be treated as utf-8, but that's what we do, and that's why
	we get an error.

	My first thought when looking at this was to spot when the
	PyString_FromString call failed with a UnicodeDecodeError and silently
	ignore the error.  This would mean that GDB would print the source
	without styling, but would also avoid the annoying exception message.

	However, I also make use of `pygmentize`, a command line wrapper
	around the Python pygments module, which I use to apply syntax
	highlighting in the output of `less`.  And this command line wrapper
	is quite happy to syntax highlight my source file that contains non
	utf-8 characters, so it feels like the problem should be solvable.

	It turns out that inside the pygments module there is already support
	for guessing the encoding of the incoming file content, if the
	incoming content is not already a Unicode string.  This is what
	happens for Python 2 where the incoming content is of `str` type.

	We could try and make GDB smarter when it comes to converting C
	strings into Python Unicode objects; this would probably require us to
	just try a couple of different encoding schemes rather than just
	giving up after utf-8.

	However, I figure, why bother?  The pygments module already does this
	for us, and the colorize API is not part of the documented external
	API of GDB.  So, why not just change the colorize API, instead of the
	content being a Unicode string (for Python 3), lets just make the
	content be a bytes object.  The pygments module can then take
	responsibility for guessing the encoding.

	So, currently, the colorize API receives a unicode object, and returns
	a unicode object.  I propose that the colorize API receive a bytes
	object, and return a bytes object.

	Remove global wrap_here function
	This removes the global wrap_here function, so that future calls
	cannot be introduced.  Instead, all callers must use the method on the
	appropriate ui_file.

	This temporarily moves the implementation of this method to utils.c.
	This will change once the remaining patches to untangle the pager have
	been written.

2022-01-26  Tom Tromey  <tom@tromey.com>

	Always call the wrap_here method
	This changes all existing calls to wrap_here to call the method on the
	appropriate ui_file instead.  The choice of ui_file is determined by
	context.

2022-01-26  Tom Tromey  <tom@tromey.com>

	Add ui_file::wrap_here
	Right now, wrap_here is a global function.  In the long run, we'd like
	output streams to be relatively self-contained objects, and having a
	global function like this is counter to that goal.  Also, existing
	code freely mixes writes to some parameterized stream with calls to
	wrap_here -- but wrap_here only really affects gdb_stdout, so this is
	also incoherent.

	This step is a patch toward making wrap_here more sane.  It adds a
	wrap_here method to ui_file and changes ui_out implementations to use
	it.

2022-01-26  Tom Tromey  <tom@tromey.com>

	Convert wrap_here to use integer parameter
	I think it only really makes sense to call wrap_here with an argument
	consisting solely of spaces.  Given this, it seemed better to me that
	the argument be an int, rather than a string.  This patch is the
	result.  Much of it was written by a script.

	gdb/python: improve the auto help text for gdb.Parameter
	This commit attempts to improve the help text that is generated for
	gdb.Parameter objects when the user fails to provide their own
	documentation.

	Documentation for a gdb.Parameter is currently pulled from two
	sources: the class documentation string, and the set_doc/show_doc
	class attributes.  Thus, a fully documented parameter might look like
	this:

	  class Param_All (gdb.Parameter):
	     """This is the class documentation string."""

	     show_doc = "Show the state of this parameter"
	     set_doc = "Set the state of this parameter"

	     def get_set_string (self):
	        val = "on"
	        if (self.value == False):
	           val = "off"
	        return "Test Parameter has been set to " + val

	     def __init__ (self, name):
	        super (Param_All, self).__init__ (name, gdb.COMMAND_DATA, gdb.PARAM_BOOLEAN)
	        self._value = True

	  Param_All ('param-all')

	Then in GDB we see this:

	  (gdb) help set param-all
	  Set the state of this parameter
	  This is the class documentation string.

	Which is fine.  But, if the user skips both of the documentation parts
	like this:

	  class Param_None (gdb.Parameter):

	     def get_set_string (self):
	        val = "on"
	        if (self.value == False):
	           val = "off"
	        return "Test Parameter has been set to " + val

	     def __init__ (self, name):
	        super (Param_None, self).__init__ (name, gdb.COMMAND_DATA, gdb.PARAM_BOOLEAN)
	        self._value = True

	  Param_None ('param-none')

	Now in GDB we see this:

	  (gdb) help set param-none
	  This command is not documented.
	  This command is not documented.

	That's not great, the duplicated text looks a bit weird.  If we drop
	different parts we get different results.  Here's what we get if the
	user drops the set_doc and show_doc attributes:

	  (gdb) help set param-doc
	  This command is not documented.
	  This is the class documentation string.

	That kind of sucks, we say it's undocumented, then proceed to print
	the documentation.  Finally, if we drop the class documentation but
	keep the set_doc and show_doc:

	  (gdb) help set param-set-show
	  Set the state of this parameter
	  This command is not documented.

	That seems OK.

	So, I think there's room for improvement.

	With this patch, for the four cases above we now see this:

	  # All values provided by the user, no change in this case:
	  (gdb) help set param-all
	  Set the state of this parameter
	  This is the class documentation string.

	  # Nothing provided by the user, the first string is now different:
	  (gdb) help set param-none
	  Set the current value of 'param-none'.
	  This command is not documented.

	  # Only the class documentation is provided, the first string is
	  # changed as in the previous case:
	  (gdb) help set param-doc
	  Set the current value of 'param-doc'.
	  This is the class documentation string.

	  # Only the set_doc and show_doc are provided, this case is unchanged
	  # from before the patch:
	  (gdb) help set param-set-show
	  Set the state of this parameter
	  This command is not documented.

	The one place where this change might be considered a negative is when
	dealing with prefix commands.  If we create a prefix command but don't
	supply the set_doc / show_doc strings, then this is what we saw before
	my patch:

	  (gdb) python Param_None ('print param-none')
	  (gdb) help set print
	  set print, set pr, set p
	  Generic command for setting how things print.

	  List of set print subcommands:

	  ... snip ...
	  set print param-none -- This command is not documented.
	  ... snip ...

	And after my patch:

	  (gdb) python Param_None ('print param-none')
	  (gdb) help set print
	  set print, set pr, set p
	  Generic command for setting how things print.

	  List of set print subcommands:

	  ... snip ...
	  set print param-none -- Set the current value of 'print param-none'.
	  ... snip ...

	This seems slightly less helpful than before, but I don't think its
	terrible.

	Additionally, I've changed what we print when the get_show_string
	method is not provided in Python.

	Back when gdb.Parameter was first added to GDB, we didn't provide a
	show function when registering the internal command object within
	GDB.  As a result, GDB would make use of its "magic" mangling of the
	show_doc string to create a sentence that would display the current
	value (see deprecated_show_value_hack in cli/cli-setshow.c).

	However, when we added support for the get_show_string method to
	gdb.Parameter, there was an attempt to maintain backward compatibility
	by displaying the show_doc string with the current value appended, see
	get_show_value in py-param.c.  Unfortunately, this isn't anywhere
	close to what deprecated_show_value_hack does, and the results are
	pretty poor, for example, this is GDB before my patch:

	  (gdb) show param-none
	  This command is not documented. off

	I think we can all agree that this is pretty bad.

	After my patch, we how show this:

	  (gdb) show param-none
	  The current value of 'param-none' is "off".

	Which at least is a real sentence, even if it's not very informative.

	This patch does change the way that the Python API behaves slightly,
	but only in the cases when the user has missed providing GDB with some
	information.  In most cases I think the new behaviour is a lot better,
	there's the one case (noted above) which is a bit iffy, but I think is
	still OK.

	I've updated the existing gdb.python/py-parameter.exp test to cover
	the modified behaviour.

	Finally, I've updated the documentation to (I hope) make it clearer
	how the various bits of help text come together.

	gdb/python: add gdb.history_count function
	Add a new function gdb.history_count to the Python api, this function
	returns an integer, the number of items in GDB's value history.

	This is useful if you want to pull items from the history by their
	absolute number, for example, if you wanted to show a complete history
	list.  Previously we could figure out how many items are in the
	history list by trying to fetch the items, and then catching the
	exception when the item is not available, but having this function
	seems nicer.

	Reference array of structs instead of first member during memcpy
	aarch64-tdep.c defines the following macro:

	#define MEM_ALLOC(MEMS, LENGTH, RECORD_BUF) \
	        do  \
	          { \
	            unsigned int mem_len = LENGTH; \
	            if (mem_len) \
	              { \
	                MEMS =  XNEWVEC (struct aarch64_mem_r, mem_len);  \
	                memcpy(&MEMS->len, &RECORD_BUF[0], \
	                       sizeof(struct aarch64_mem_r) * LENGTH); \
	              } \
	          } \
	          while (0)

	This is simlpy allocating a new array and copying it. However, for
	the destination address, it is actually copying into the first member
	of the first element of the array (`&MEMS->len"). This elicits a
	warning with GCC 12:

	../../binutils-gdb/gdb/aarch64-tdep.c: In function ‘int aarch64_process_record(gdbarch*, regcache*, CORE_ADDR)’:
	../../binutils-gdb/gdb/aarch64-tdep.c:3711:23: error: writing 16 bytes into a region of size 8 [-Werror=stringop-overflow=]

	../../binutils-gdb/gdb/aarch64-tdep.c:4394:3: note: in expansion of macro ‘MEM_ALLOC’

	 3721 |   uint64_t len;    /* Record length.  */
	      |            ^~~

	The simple fix is to reference the array, `MEMS' as the destination of the copy.

	Tested by rebuilding.

	gdb: add string_file::release method
	A common pattern for string_file is to want to move out the internal
	string buffer, because it is the result of the computation that we want
	to return.  It is the reason why string_file::string returns a non-const
	reference, as explained in the comment.  I think it would make sense to
	have a dedicated method for that instead and make string_file::string
	return a const reference.

	This allows removing the explicit std::move in the typical case.  Note
	that compile_program::compute was missing a move, meaning that the
	resulting string was copied.  With the new version, it's not possible to
	forget to move.

	Add a way to temporarily set a gdb parameter from Python
	It's sometimes useful to temporarily set some gdb parameter from
	Python.  Now that the 'endian' crash is fixed, and now that the
	current language is no longer captured by the Python layer, it seems
	reasonable to add a helper function for this situation.

	This adds a new gdb.with_parameter function.  This creates a context
	manager which temporarily sets some parameter to a specified value.
	The old value is restored when the context is exited.  This is most
	useful with the Python "with" statement:

	   with gdb.with_parameter('language', 'ada'):
	      ... do Ada stuff

	This also adds a simple function to set a parameter,
	gdb.set_parameter, as suggested by Andrew.

	Fix another crash with gdb parameters in Python
	While looking into the language-capturing issue, I found another way
	to crash gdb using parameters from Python:

	(gdb) python print(gdb.parameter('endian'))

	(This is related to PR python/12188, though this patch isn't going to
	fix what that bug is really about.)

	The problem here is that the global variable that underlies the
	"endian" parameter is initialized to NULL.  However, that's not a
	valid value for an "enum" set/show parameter.

	My understanding is that, in gdb, an "enum" parameter's underlying
	variable must have a value that is "==" (not just strcmp-equal) to one
	of the values coming from the enum array.  This invariant is relied on
	in various places.

	I started this patch by fixing the problem with "endian".  Then I
	added some assertions to add_setshow_enum_cmd to try to catch other
	problems of the same type.

	This patch fixes all the problems that I found.  I also looked at all
	the calls to add_setshow_enum_cmd to ensure that they were all
	included in the gdb I tested.  I think they are: there are no calls in
	nat-* files, or in remote-sim.c; and I was trying a build with all
	targets, Python, and Guile enabled.

2022-01-26  Tom Tromey  <tromey@adacore.com>

	Change how Python architecture and language are handled
	Currently, gdb's Python layer captures the current architecture and
	language when "entering" Python code.  This has some undesirable
	effects, and so this series changes how this is handled.

	First, there is code like this:

	  gdbpy_enter enter_py (python_gdbarch, python_language);

	This is incorrect, because both of these are NULL when not otherwise
	assigned.  This can cause crashes in some cases -- I've added one to
	the test suite.  (Note that this crasher is just an example, other
	ones along the same lines are possible.)

	Second, when the language is captured in this way, it means that
	Python code cannot affect the current language for its own purposes.
	It's reasonable to want to write code like this:

	    gdb.execute('set language mumble')
	    ... stuff using the current language
	    gdb.execute('set language previous-value')

	However, this won't actually work, because the language is captured on
	entry.  I've added a test to show this as well.

	This patch changes gdb to try to avoid capturing the current values.
	The Python concept of the current gdbarch is only set in those few
	cases where a non-default value is computed or needed; and the
	language is not captured at all -- instead, in the cases where it's
	required, the current language is temporarily changed.

	We found a case where --gc-sections can cause gdb to set an invalid

	two locations, one of which is 0x0.

	The code in lnp_state_machine::check_line_address is intended to
	filter out this sort of problem, but in this case, the entire CU is
	empty, causing unrelocated_lowpc==0x0 -- which circumvents the check.

	It seems to me that if a CU is empty like this, then it is ok to

	Add `set print repeats' tests for C/C++ arrays
	Add `set print repeats' tests for C/C++ arrays, complementing one for
	Fortran arrays and covering the different interpretation of the `set
	print elements' setting in particular where the per-dimension count of
	the elements handled is matched against the trigger rather than the
	total element count as with Fortran arrays.

2022-01-19  Maciej W. Rozycki  <macro@embecosm.com>

	Respect `set print repeats' with Fortran arrays
	Implement `set print repeats' handling for Fortran arrays.  Currently
	the setting is ignored and always treated as if no limit was set.

	Unlike the generic array walker implemented decades ago the Fortran one
	is a proper C++ class.  Rather than trying to mimic the old walker then,
	which turned out a bit of a challenge where interacting with the `set
	print elements' setting, write it entirely from scratch, by adding an
	extra specialization handler method for processing dimensions other than
	the innermost one and letting the specialization class call the `walk_1'
	method from the handler as it sees fit.  This way repeats can be tracked
	and the next inner dimension recursed into as a need arises only, or
	unconditionally in the base class.

	Keep track of the dimension number being handled in the class rather as
	a parameter to the walker so that it does not have to be passed across
	by the specialization class.

	Use per-dimension element count tracking, needed to terminate processing
	early when the limit set by `set print elements' is hit.  This requires
	extra care too where the limit triggers exactly where another element
	that is a subarray begins.  In that case rather than recursing we need
	to terminate processing or lone `(...)' would be printed.  Additionally
	if the skipped element is the last one in the current dimension we need
	to print `...' by hand, because `continue_walking' won't print it at the
	upper level, because it can see the last element has already been taken
	care of.

	Preserve the existing semantics of `set print elements' where the total
	count of the elements handled is matched against the trigger level which
	is unlike with the C/C++ array printer where the per-dimension element
	count is used instead.

	Output now looks like:

	(gdb) set print repeats 4
	(gdb) print array_2d
	$1 = ((2, <repeats 5 times>) <repeats 5 times>)
	(gdb) set print elements 12
	(gdb) print array_2d
	$2 = ((2, <repeats 5 times>) (2, <repeats 5 times>) (2, 2, ...) ...)
	(gdb)

	for a 5 by 5 array filled with the value of 2.

	Amend existing test cases accordingly that rely on the current incorrect
	behavior and explicitly request that there be no limit for printing
	repeated elements there.

	Add suitable test cases as well covering sliced arrays in particular.

	Simplify Ada catchpoints
	All the Ada catchpoints use the same breakpoint_ops contents, because
	the catchpoint itself records its kind.  This patch simplifies the
	code by removing the redundant ops structures.

	Move "catch exec" to a new file
	The "catch exec" code is reasonably self-contained, and so this patch
	moves it out of breakpoint.c (the second largest source file in gdb)
	and into a new file, break-catch-exec.c.

	Move "catch fork" to a new file
	The "catch fork" code is reasonably self-contained, and so this patch
	moves it out of breakpoint.c (the second largest source file in gdb)
	and into a new file, break-catch-fork.c.

	Unify "catch fork" and "catch vfork"
	I noticed that "catch fork" and "catch vfork" are nearly identical.
	This patch simplifies the code by unifying these two cases.

	Move gdb_regex to gdbsupport
	This moves the gdb_regex convenience class to gdbsupport.

	Introduce gdb-hashtab module in gdbsupport
	gdb has some extensions and helpers for working with the libiberty
	hash table.  This patch consolidates these and moves them to
	gdbsupport.

	Move gdb obstack code to gdbsupport
	This moves the gdb-specific obstack code -- both extensions like
	obconcat and obstack_strdup, and things like auto_obstack -- to
	gdbsupport.

	Move gdb_argv to gdbsupport
	This moves the gdb_argv class to a new header in gdbsupport.

	Simplify event_location_probe
	event_location_probe currently stores two strings, but really only
	needs one.  This patch simplifies it and removes some unnecessary
	copies as well.

	Use std::string in event_location
	This changes event_location to use std::string, removing some manual
	memory management, and an unnecessary string copy.

	Split event_location into subclasses
	event_location uses the old C-style discriminated union approach.
	However, it's better to use subclassing, as this makes the code
	clearer and removes some chances for error.  This also enables future
	cleanups to avoid manual memory management and copies.

	Remove EL_* macros from location.c
	This patch removes the old-style EL_* macros from location.c.  This
	cleans up the code by itself, IMO, but also enables further cleanups
	in subsequent patches.

	Boolify explicit_to_string_internal
	This changes explicit_to_string_internal to use 'bool' rather than
	'int'.

	Remove a use of xfree in location.c
	This small cleanup removes a use of xfree from location.c, by
	switching to unique_xmalloc_ptr.  One function is only used in
	location.c, so it is made static.  And, another function is changed to
	avoid a copy.

	gdb: preserve `|` in connection details string
	Consider this GDB session:

	  $ gdb -q
	  (gdb) target remote  | gdbserver - ~/tmp/hello.x
	  Remote debugging using | gdbserver - ~/tmp/hello.x
	  ... snip ...
	  (gdb) info connections
	    Num  What                              Description
	  * 1    remote gdbserver - ~/tmp/hello.x  Remote target using gdb-specific protocol
	  (gdb) python conn = gdb.selected_inferior().connection
	  (gdb) python print(conn.details)
	  gdbserver - ~/tmp/hello.x
	  (gdb)

	I think there are two things wrong here, first in the "What" column of
	the 'info connections' output, I think the text should be:

	  remote | gdbserver - ~/tmp/hello.x

	to correctly show the user how the connection was established.  And in
	a similar fashion, I think that the `details` string of the
	gdb.TargetConnection object should be:

	  | gdbserver - ~/tmp/hello.x

	This commit makes this change.  Currently the '|' is detected and
	removed in gdb/serial.c.  The string passed to the pipe_ops
	structure (from gdb/ser-pipe.c), doesn't then, contain the `|`, this
	is instead implied by the fact that it is a pipes based implementation
	of the serial_ops interface.

	After this commit we still detect the `|` in gdb/serial.c, but we now
	store the full string (including the `|`) in the serial::name member
	variable.

	For pipe based serial connections, this name is only used for
	displaying the two fields I mention above, and in pipe_open (from
	gdb/ser-pipe.c), and in pipe_open, we now know to skip over the `|`.

	The benefit I see from this change is that GDB's output now more
	accurately reflects the commands used to start a target, thus making
	it easier for a user to understand what is going on.

	bfd/elf64-ppc.c: fix clang -Wbitwise-instead-of-logical warning in ppc64_elf_check_init_fini
	I see this error with clang-14:

	      CC       elf64-ppc.lo
	    /home/smarchi/src/binutils-gdb/bfd/elf64-ppc.c:13131:11: error: use of bitwise '&' with boolean operands [-Werror,-Wbitwise-instead-of-logical]
	      return (check_pasted_section (info, ".init")
	             ~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

	Fix by replacing & with &&.  But given that the check_pasted_section
	function has side-effects and we want to make sure both calls are made,
	assign to temporary variables before evaluating the `&&`.

	PR28029, debuginfod tests
	binutils/NEWS says of the change in --process-links semantics:
	  If other debug section display options are also enabled (eg
	  --debug-dump=info) then the contents of matching sections in both the main
	  file and the separate debuginfo file *will* be displayed.  This is because in
	  most cases the debug section will only be present in one of the files.

	Implying that debug info is dumped without --process-links.  Indeed
	that appears to be the case for readelf.  This does the same for
	objdump.

	PowerPC64 DT_RELR
	PowerPC64 takes a more traditional approach to DT_RELR than x86.  Count
	relative relocs in check_relocs, allocate space for them and output in
	the usual places but not doing so when enable_dt_relr.  DT_RELR is
	sized in the existing ppc stub relaxation machinery, run via the
	linker's ldemul_after_allocation hook.  DT_RELR is output in the same
	function that writes ppc stubs, run via ldemul_finish.

	This support should be considered experimental.

	x86: adjust struct instr_info field types
	Now that this lives on the stack, let's have it be a little less
	wasteful in terms of space. Switch boolean fields to "bool" (also when
	this doesn't change their size) and also limit the widths of "rex",
	"rex_used", "op_ad", and "op_index". Do a little bit of re-ordering as
	well to limit the number of padding holes.

	x86: drop index16 field
	There's a single use on a generally infrequently taken code path. Put
	the necessary conditional there instead.

	x86: drop most Intel syntax register name arrays
	By making use of, in particular, oappend_maybe_intel() there's no need
	for this redundant set of static data.

	x86: fold variables in memory operand index handling
	There's no real need for the pseudo-boolean "haveindex" or for separate
	32-bit / 64-bit index pointers. Fold them into a single "indexes" and
	set that uniformly to AT&T names, compensating by emitting the register
	name via oappend_maybe_intel().

	x86: constify disassembler static data
	Now that the code is intended to be largely thread-safe, we'd better not
	have any writable static objects.

	gdb.dlang/demangle.exp: update expected output for _D8demangle4testFnZv
	Since commit ce2d3708bc8b ("Synchronize binutils libiberty sources with
	gcc version."), I see this failure:

	    demangle _D8demangle4testFnZv^M
	    demangle.test(typeof(null))^M
	    (gdb) FAIL: gdb.dlang/demangle.exp: _D8demangle4testFnZv

	The commit imported the commit 0e32a5aa8bc9 ("libiberty: Add support for
	D `typeof(*null)' types") from the gcc repository.  That commit includes
	an update to libiberty/testsuite/d-demangle-expected, which updates a
	test for the exact same mangled name:

	     _D8demangle4testFnZv
	    -demangle.test(none)
	    +demangle.test(typeof(null))

	I don't know anything about D, but give that the change was made by Iain
	Buclaw, the D language maintainer, I trust him on that.

	Fix our test by updating the expected output in the same way.

	Note: it's not really useful to have all these D demangling tests in the
	GDB testsuite, since there are demangling tests in libiberty.  We should
	consider removing them, but we first need to make sure that everything
	that is covered in gdb/testsuite/gdb.dlang/demangle.exp is also covered
	in libiberty/testsuite/d-demangle-expected.

	x86: drop ymmxmm_mode
	This enumerator is not used by any table entry.

	x86: share yet more VEX table entries with EVEX decoding
	On top of prior similar work more opportunities have appeared in the
	meantime. Note that this also happens to address the prior lack of
	decoding of EVEX.L'L for VMOV{L,H}P{S,D} and VMOV{LH,HL}PS.

	x86: consistently use scalar_mode for AVX512-FP16 scalar insns
	For some reason the original AVFX512F insns were not taken as a basis
	here, causing unnecessary divergence. While not an active issue, it is
	still relevant to note that OP_XMM() has special treatment of e.g.
	scalar_mode (marking broadcast as invalid). Such would better be
	consistent for all sufficiently similar insns.

	x86: record further wrong uses of EVEX.b
	For one EVEX.W set does not imply EVEX.b is uniformly valid. Reject it
	for modes which occur for insns allowing for EVEX.W to be set (noticed
	with VMOV{H,L}PD and VMOVDDUP, and only in AT&T mode, but not checked
	whether further insns would also have been impacted; I expect e.g.
	VCMPSD would have had the same issue). And then the present concept of
	broadcast makes no sense at all when the memory operand of an insn is
	the destination.

2022-01-14  Jan Beulich  <jbeulich@suse.com>

	x86: reduce AVX512 FP set of insns decoded through vex_w_table[]
	Like for AVX512-FP16, there's not that many FP insns where going through
	this table is easier / cheaper than using suitable macros. Utilize %XS
	and %XD more to eliminate a fair number of table entries.

	While doing this I noticed a few anomalies. Where lines get touched /
	moved anyway, these are being addressed right here:
	- vmovshdup used EXx for its 2nd operand, thus displaying seemingly
	  valid broadcast when EVEX.b is set with a memory operand; use
	  EXEvexXNoBcst instead just like vmovsldup already does
	- vmovlhps used EXx for its 3rd operand, when all sibling entries use
	  EXq; switch to EXq there for consistency (the two differ only for
	  memory operands)

2022-01-14  Jan Beulich  <jbeulich@suse.com>

	x86: reduce AVX512-FP16 set of insns decoded through vex_w_table[]
	Like already indicated during review of the original submission, there's
	really only very few insns where going through this table is easier /
	cheaper than using suitable macros. Utilize %XH more and introduce
	similar %XS and %XD (which subsequently can be used for further table
	size reduction).

	While there also switch to using oappend() in 'XH' macro processing.

	elf: Remove the 1-page gap before the RELRO segment
	The existing RELRO scheme may leave a 1-page gap before the RELRO segment
	and align the end of the RELRO segment to the page size:

	  [18] .eh_frame    PROGBITS    408fa0 008fa0 005e80 00   A  0   0  8

	gdb: don't use -Wmissing-prototypes with g++
	This commit aims to not make use of -Wmissing-prototypes when
	compiling with g++.

	Use of -Wmissing-prototypes was added with this commit:

	  commit a0761e34f054767de6d6389929d27e9015fb299b
	  Date:   Wed Mar 11 15:15:12 2020 -0400

	      gdb: enable -Wmissing-prototypes warning

	Because clang can provide helpful warnings with this flag.
	Unfortunately, g++ doesn't accept this flag, and will give this
	warning:

	  cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC but not for C++

	In theory the fact that this flag is not supported should be detected
	by the configure check in gdbsupport/warning.m4, but for users of
	ccache, this check doesn't work due to a long standing ccache issue:

	  https://github.com/ccache/ccache/issues/738

	The ccache problem is that -W... options are reordered on the command
	line, and so -Wmissing-prototypes is seen before -Werror.  Usually
	this doesn't matter, but the above warning (about the flag not being
	valid) is issued before the -Werror flag is processed, and so is not
	fatal.

	There have been two previous attempts to fix this that I'm aware of.
	The first is:

	  https://sourceware.org/pipermail/gdb-patches/2021-September/182148.html

	In this attempt, instead of just relying on a compile to check if a
	flag is valid, the proposal was to both compile and link.  As linking
	doesn't go through ccache, we don't suffer from the argument
	reordering problem, and the link phase will correctly fail when using
	-Wmissing-prototypes with g++.  The configure script will then disable
	the use of this flag.

	This approach was rejected, and the suggestion was to only add the
	-Wmissing-prototypes flag if we are compiling with gcc.

	The second attempt, attempts this approach, and can be found here:

	  https://sourceware.org/pipermail/gdb-patches/2021-November/183076.html

	This attempt only adds the -Wmissing-prototypes flag is the value of
	GCC is not 'yes'.  This feels like it is doing the right thing,
	unfortunately, the GCC flag is really a 'is gcc like' flag, not a
	strict, is gcc check.  As such, GCC is set to 'yes' for clang, which
	would mean the flag was not included for clang or gcc.  The entire
	point of the original commit was to add this flag for clang, so
	clearly the second attempt is not sufficient either.

	In this new attempt I have added gdbsupport/compiler-type.m4, this
	file defines AM_GDB_COMPILER_TYPE.  This macro sets the variable
	GDB_COMPILER_TYPE to either 'gcc', 'clang', or 'unknown'.  In future
	the list of values might be extended to cover other compilers, if this
	is ever useful.

	I've then modified gdbsupport/warning.m4 to only add the problematic
	-Wmissing-prototypes flag if GDB_COMPILER_TYPE is not 'gcc'.

	I've tested this with both gcc and clang and see the expected results,
	gcc no longer attempts to use the -Wmissing-prototypes flag, while
	clang continues to use it.

	When compiling using ccache, I am no longer seeing the warning.

	gdb: add some extra debug information to attach_command
	While working on another patch I wanted to add some extra debug
	information to the attach_command function.  This required me to add a
	new function to convert the thread_info::state variable to a string.

	The new debug might be useful to others, and the state to string
	function might be useful in other locations, so I thought I'd merge
	it.

	gdb: testsuite: make string[] type as char in gdb.base/charset.c
	This reverts the commit ff656e2e1cb1 ("gdb: testsuite: fix failed
	testcases in gdb.base/charset.exp").

	The original test code has no problem. On an architecture where
	char is signed, then both 'A' and ebcdic_us_string[7] will yield
	-63, which makes the equality true. On an architecture where char
	is unsigned, then both 'A' and ebcdic_us_string[7] will yield 193,
	which also makes the equality true.

	The test cases only failed on LoongArch. The default type of char
	is signed char on LoongArch, like x86-64. But when use gdb print
	command on LoongArch, the default type of char is unsigned char,
	this is wrong, I will look into it later, sorry for that.

	On LoongArch:

	  $ cat test_char.c
	  #include <stdio.h>

	  int main()
	  {
	          char c1 = 193;
	          unsigned char c2 = 193;

	          printf("%d\n", c1);
	          printf("%d\n", c1 == c2);

	          return 0;
	  }
	  $ gcc test_char.c -o test_char
	  $ ./test_char
	  -63
	  0

	  (gdb) set target-charset EBCDIC-US
	  (gdb) print 'A'
	  $1 = 193 'A'
	  (gdb) print /c 'A'
	  $2 = 193 'A'
	  (gdb) print /u 'A'
	  $3 = 193
	  (gdb) print /d 'A'
	  $4 = -63
	  (gdb) print /x 'A'
	  $5 = 0xc1

	supports HW watchpoints or not.  If the Power processor doesn't support HW
	watchpoints the proceedure skip_hw_watchpoint_tests will return 1 to
	disable the various HW watchpoint tests.

	The patch has been tested on Power 9, processor revesions 2.2 and 2.3.  The

	gdb/testsuite: fix gdb.python/py-events.exp for finding process id
	When executed with --target_board=native-extended-gdbserver, the
	gdb.python/py-events.exp test errors out with

	  ERROR: tcl error sourcing /path/to/gdb/testsuite/gdb.python/py-events.exp.
	  ERROR: can't read "process_id": no such variable
	      while executing
	  "lappend expected "ptid: \\($process_id, $process_id, 0\\)" "address: $addr""

	  "uplevel #0 source /path/to/gdb/testsuite/gdb.python/py-events.exp"
	      invoked from within
	  "catch "uplevel #0 source $test_file_name""

	There are multiple problems around this:

	1. The process_id variable is not initialized to a default value.

	2. The test attempts to find the PID of the current thread, but the
	   regexp that it uses is not tailored for the output printed by the
	   remote target.

	3. The test uses "info threads" to find the current thread PID.
	   Using the "thread" command instead is simpler.

	Fix these problems.

	Don't mention "serial" in target remote description
	PR remote/9177 points out that "info files" mentions "serial" a couple
	of times:

	    Remote serial target in gdb-specific protocol:
	    Debugging a target over a serial line.

	However, often the remote target isn't really a serial connection.

	It seems to me that this text could be a bit clearer; and furthermore
	since "info files" prints the target's long description,
	remote_target::files_info doesn't really add much and can simply be
	removed.

	Regression tested on x86-64 Fedora 34.

	x86: Add DT_RELR support
	DT_RELR is implemented with linker relaxation:

	1. During linker relaxation, we scan input relocations with the same
	logic in relocate_section to determine if a relative relocation should
	be generated and save the relative relocation candidate information for
	sizing the DT_RELR section later after all symbols addresses can be
	determined.  For these relative relocations which can't be placed in
	the DT_RELR section, they will be placed in the rela.dyn/rel.dyn
	section.
	2. When DT_RELR is enabled, _bfd_elf_map_sections_to_segments calls a
	backend function to size the DT_RELR section which will compute the
	DT_RELR section size and tell ldelf_map_segments to layout sections
	again when the DT_RELR section size has been increased.
	3. After regular symbol processing is finished, bfd_elf_final_link calls
	a backend function to finish the DT_RELR section.

	gdb: add 'maint set/show gnu-source-highlight enabled' command
	In a later commit I want to address an issue with the Python pygments
	based code styling solution.  As this approach is only used when the
	GNU Source Highlight library is not available, testing bugs in this
	area can be annoying, as it requires GDB to be rebuilt with use of GNU
	Source Highlight disabled.

	This commit adds a pair of new maintenance commands:

	  maintenance set gnu-source-highlight enabled on|off
	  maintenance show gnu-source-highlight enabled

	these commands can be used to disable use of the GNU Source Highlight
	library, allowing me, in a later commit, to easily test bugs that
	would otherwise be masked by GNU Source Highlight being used.

	I made this a maintenance command, rather than a general purpose
	command, as it didn't seem like this was something a general user
	would need to adjust.  We can always convert the maintenance command
	to a general command later if needed.

	There's no test for this here, but this feature will be used in a
	later commit.

2022-01-12  Andrew Burgess  <aburgess@redhat.com>

	gdb: erase items from the source_cache::m_offset_cache
	The source_cache class has two member variables m_source_map, which
	stores the file contents, and m_offset_cache, which stores offsets
	into the file contents.

	As source files are read the contents of the file, as well as the
	offset data, are stored in the cache using these two member variables.

	Whenever GDB needs either the files contents, or the offset data,
	source_cache::ensure is called.  This function looks for the file in
	m_source_map, and if it's found then this implies the file is also in
	m_offset_cache, and we're done.

	If the file is not in m_source_map then GDB calls
	source_cache::get_plain_source_lines to open the file and read its
	contents.  ::get_plain_source_lines also calculates the offset data,
	which is then inserted into m_offset_cache.

	Back in ::ensure, the file contents are added into m_source_map.  And
	finally, if m_source_map contains more than MAX_ENTRIES, an entry is
	removed from m_source_map.

	The problem is entries are not removed from m_offset_cache at the same
	time.

	This means that if a program contains enough source files, GDB will
	hold at most MAX_ENTRIES cached source file contents, but can contain
	offsets data for every source file.

	Now, the offsets data is going to be smaller than the cached file
	contents, so maybe there's no harm here.  But, when we reload the file
	contents we always recalculate the offsets data.  And, when we
	::get_line_charpos asking for offset data we still call ::ensure which
	will ends up loading and caching the file contents.

	So, given the current code does the work of reloading the offset data
	anyway, we may as well save memory by capping m_offset_cache to
	MAX_ENTRIES just like we do m_source_map.

	That's what this commit does.

	There should be no user visible changes after this commit, except for
	ever so slightly lower memory usage in some cases.

2022-01-12  Andrew Burgess  <aburgess@redhat.com>

	gdb: new 'maint flush source-cache' command
	This commit adds a new 'maint flush source-cache' command, this
	flushes the cache of source file contents.

	After flushing GDB is forced to reread source files the next time any
	source lines are to be displayed.

	I've added a test for this new feature.  The test is a little weird,
	in that it modifies a source file after compilation, and makes use of
	the cache flush so that the changes show up when listing the source
	file.  I'm not sure when such a situation would ever crop up in real
	life, but maybe we can imagine such cases.

	In reality, this command is useful for testing the syntax highlighting
	within GDB, we can adjust the syntax highlighting settings, flush the
	cache, and then get the file contents re-highlighted using the new
	settings.

	gdb: rename lin-lwp to linux-nat in set/show debug
	Rename 'set debug lin-lwp' to 'set debug linux-nat' and 'show debug
	lin-lwp' to 'show debug linux-nat'.

	I've updated the documentation and help text to match, as well as
	making it clear that the debug that is coming out relates to all
	aspects of Linux native inferior support, not just the LWP aspect of
	it.

	The boundary between general "native" target debug, and the lwp
	specific part of that debug was always a little blurry, but the actual
	debug variable inside GDB is debug_linux_nat, and the print routine
	linux_nat_debug_printf, is used throughout the linux-nat.c file, not
	just for lwp related debug, so the new name seems to make more sense.

	objdump, readelf: Emit "CU:" format only when wide output is requested
	As pre-approved by Alan in
	https://sourceware.org/pipermail/binutils/2021-September/118019.html
	and I believe people have run into getting testsuite failures for
	test-environments with "long" directory names, at least once more
	since that time.  Enough.  I grepped the gas, binutils and ld
	testsuites for "CU:" to catch target-specific occurrences, but I
	noticed none.  I chose to remove "CU:" on the objdump tests instead of
	changing options to get the wide format, so as to keep the name of the
	test consistent with actual options; but added it to the readelf
	options for the gas test as I believe the "CU:" format is preferable.

	Tested for cris-elf and native x86_64-pc-linux-gnu.

	I had cause to regenerate gdbsupport/Makefile.in, and noticed some

	I suspect that this was caused by the end of year date range update

	The Makefile.in contains two date ranges.  The first range appears to
	be the date range for the version of automake being used, that is the
	range runs up to 2017 only, when automake 1.15.1 was released.

	The second date range in Makefile.in represents the date range for the

	Reduce use of unfiltered output in Darwin code
	The Darwin code uses unfiltered output liberally.  This patch changes
	this code to send some output to gdb_stdlog (in some cases via the use
	of debug_prefixed_printf_cond_nofunc), or to gdb_stderr, or to simply
	switch to filtered output.

	Note that I didn't switch inferior_debug to use
	debug_prefixed_printf_cond_nofunc, because that would affect the
	output by removing the information about the inferior.  I wasn't sure
	if this was important or not, so I left it in.

	v2 of this patch uses warning rather than prints to gdb_stderr, and
	removes some trailing whitespace.

	I can't compile this patch, so it's "best effort".

	gdb/hurd: handle inferiors exiting
	While testing on GNU/Hurd (i386) I noticed that GDB crashes when an
	inferior exits, with this error:

	  inferior.c:293: internal-error: inferior* find_inferior_pid(process_stratum_target*, int): Assertion `pid != 0' failed.

	The problem appears to be in gnu_nat_target::wait.

	We always set inferior_ptid to null_ptid before calling target_wait,
	this has been the case since the multi-target changes were made to GDB
	in commit:

	  commit 5b6d1e4fa4fc6827c7b3f0e99ff120dfa14d65d2
	  Date:   Fri Jan 10 20:06:08 2020 +0000

	      Multi-target support

	With follow up changes in commit:

	  commit 24ed6739b699f329c2c45aedee5f8c7d2f54e493
	  Date:   Thu Jan 30 14:35:40 2020 +0000

	      gdb/remote: Restore support for 'S' stop reply packet

	Unfortunately, the GNU/Hurd target is still relying on the value of
	inferior_ptid in the case where an inferior exits - we return the
	value of inferior_ptid as the pid of the process that exited.  This
	was fine in the single target world, where inferior_ptid identified
	the one running inferior, but this is no longer good enough.

	Instead, we should return a ptid containing the pid of the process
	that exited, as obtained from the wait event, and this is what this
	commit does.

	I've not run the full testsuite on GNU/Hurd as there appear to be lots
	of other issues with this target that makes running the full testsuite
	very painful, but I think this looks like a small easy improvement.

	ld: Extract _bfd_elf_link_iterate_on_relocs
	DT_RELR encodes consecutive R_*_RELATIVE relocations in GOT (the global
	offset table) and data sections in a compact format:

	https://groups.google.com/g/generic-abi/c/bX460iggiKg

	On some targets, R_*_RELATIVE relocations are counted and the GOT offsets
	are allocated when setting the dynamic section sizes after seeing all
	relocations.  R_*_RELATIVE relocations are generated while relocating
	sections after section layout has been finalized.

	To prepare for DT_RELR implementation on these targets, extract
	_bfd_elf_link_iterate_on_relocs from _bfd_elf_link_check_relocs so
	that a backend can scan relocations in elf_backend_always_size_sections

	For x86 targets, the old check_relocs is renamed to scan_relocs and a
	new check_relocs is added to chek input sections and create dynamic
	relocation sections so that they will be mapped to output sections.
	scan_relocs is now called from elf_backend_always_size_sections.

	Since relocations are scanned after __start, __stop, .startof. and
	.sizeof. symbols have been finalized on x86, __[start|stop]_SECNAME for
	--gc-sections -z start-stop-gc are now zero when all SECNAME sections
	been garbage collected.  This is no need for elf_x86_start_stop_gc_p.

	gdb: completion-support.exp: improve leading whitespace support
	There is a expect support library in the source tree designed to help
	developers test the auto-completion capabilities of GDB.

	One of the functions is test_gdb_complete_unique_re.  It is used
	(usually indirectly via test_gdb_complete_unique) to test that a given
	input line is completed as a given output line.  The test checks for two
	ways to do the completion: using tab-completion, or using the
	'complete' command.  To do this, calls to two dedicated functions are
	performed.  If we omit few details, we can consider that a call to

	    test_gdb_complete_unique $input $expected

	is equivalent to the two following calls:

	    test_gdb_complete_tab_unique $input $expected
	    test_gdb_complete_cmd_unique $input $expected

	When using the tab-completion, everything works as expected, but some
	care must be taken when using the 'complete' command if the given input
	has leading whitespaces.  In such situation, the output of the
	'complete' command will drop the leading whitespaces.

	The current approach is that in such situation, the input and expected
	outputs are right trimmed (i.e. all leading whitespaces are removed)
	when performing the command completion check.

	This means that the following call:

	    test_gdb_complete_unique "   $input" "   $expected"

	is almost equivalent to (again, omitting few details and arguments):

	    test_gdb_complete_tab_unique "   $input" "   $expected"
	    test_gdb_complete_cmd_unique "$input" "$expected"

	This approach comes with a problem that we encounter when running the
	tests in complete-empty.exp.  When doing so, we have:

	    Running .../gdb/testsuite/gdb.base/complete-empty.exp ...
	    DUPLICATE: gdb.base/complete-empty.exp: empty-input-line: cmd complete ""

	This is because the test file does something like:

	    test_gdb_complete_unique "" "!" " " 1
	    test_gdb_complete_unique "   " "   !" " " 1¬

	which, if we do the substitution introduced above is equivalent to:

	    test_gdb_complete_tab_unique "" "!"
	    test_gdb_complete_cmd_unique "" "!"
	    test_gdb_complete_tab_unique "   " "   !"
	    test_gdb_complete_cmd_unique "" "!"

	We see that the lines 2 and 4 are now the same, and for this reason the
	testing framework complains about DUPLICATE test names.

	To fix that, this commit proposes that instead of left trimming both
	input and expected outputs, only the expected output is trimmed.

	Care must be taken in the case the completion gives more possibilities
	than allowed by the max-completions setting.  In this case, the input
	will be repeated in the output in its left trimmed version.  This commit
	also ensures that this is taken care of.

	With this commit, the gdb.base/complete-empty.exp still passes all its
	tests but does not report the DUPLICATE anymore.

	Tested on x86_64-linux.

	gdb/testsuite: Remove duplicates from gdb.base/solib-display.exp
	When running the testsuite, I have:

	    Running .../gdb/testsuite/gdb.base/solib-display.exp ...
	    DUPLICATE: gdb.base/solib-display.exp: NO: break 25

	    DUPLICATE: gdb.base/solib-display.exp: SEP: break 25
	    DUPLICATE: gdb.base/solib-display.exp: SEP: continue

	The 'break 25' appears because the test inserts two breakpoints at the
	same location.  Fix this by only inserting the breakpoint once.

	Fix the 'continue' DUPLICATE by giving a phony name to the second
	continue: 'continue two'.

	While at it, this commit also removes a trailing space.

	This is due to the fact that the test restarts GDB twice and each time
	sets the basenames-may-differ setting.  This patch proposes to fix this
	by not restarting GDB so the setting is maintained.  It just clears the

	When running the testsuite I have:

	    Running .../gdb/testsuite/gdb.base/interp.exp ...
	    DUPLICATE: gdb.base/interp.exp: interpreter-exec mi "-var-update *"

	This is due to the fact that multiple successive instances of
	gdb_test_multiple use 'pass $cmd', but one of them forgets to reset $cmd
	to a new test name.

	Fix by using 'pass $gdb_test_name', given that the gdb_test_name is set
	by gdb_test_multiple.

	While fixing this, this patch refactors all occurrences of the following
	pattern:

	    set cmd foo
	    gdb_test_multiple $cmd $cmd {
	        -re ... {
	            pass $cmd

	        -re ... {
	            pass $gdb_test_name
	         }

	    DUPLICATE: gdb.base/miscexprs.exp: print value of !ibig.i[100]

	This is due to an explicit test name repeated across multiple tests.
	The actual test explicit names do not add much over the command from
	wich default test names are derived.

	Fix by removing the explicit test names across the file where they do
	not add value.  While at doing some cleaning, also use $gdb_test_name in
	the various uses of gdb_test_multiple.

	gdb/doc: shorten some source lines, and prevent some line breaks
	Building on the previous commit, this makes use of a trailing @ to
	split long @deffn lines in the guile.texi source file.  This splitting
	doesn't change how the document is laid out by texinfo.

	I have also wrapped keyword and argument name pairs in @w{...} to
	prevent line breaks appearing between the two.  I've currently only
	done this for the longer @deffn lines, where a line break is
	possible.  This makes the @deffn lines much nicer to read in the
	generated pdf.

2022-01-07  Andrew Burgess  <aburgess@redhat.com>

	gdb/doc: Remove (...) around guile procedure names in @deffn lines
	Most guile procedures in the guile.texi file are defined like:

	  @deffn {Scheme Procedure} name arg1 arg2 arg3

	But there are two places where we do this:

	  @deffn {Scheme Procedure} (name arg1 arg2 arg3)

	Notice the added (...).  Though this does represent how a procedure
	call is written in scheme, it's not the normal style throughout the
	manual.  I also checked the 'info guile' info page to see how they
	wrote there declarations, and they use the first style too.

	The second style also has the drawback that index entries are added as
	'(name', and so they are grouped in the '(' section of the index,
	which is not very user friendly.

	In this commit I've changed the definitions of make-command and
	make-parameter to use the first style.

	The procedure declaration lines can get pretty long with all of the
	arguments, and this was true for both of the procedures I am changing
	in this commit.  I have made use of a trailing '@' to split the deffn
	lines, and keep them under 80 characters in the texi source.  This
	makes no difference to how the final document looks.

	Finally, our current style for keyword arguments, appears to be:

	  [#:keyword-name argument-name]

	I don't really understand the reason for this, 'info guile' just seems
	to use:

	  [#:keyword-name]

	which seems just as good to me.  But I don't propose to change
	that just now.  What I do notice though, is that sometimes, texinfo
	will place a line break between the keyword-name and the
	argument-name, for example, the pdf of make-command is:

	  make-command name [#:invoke invoke] [#:command-class
	    command-class] [#:completer-class completer] [#:prefix? prefix] [#:doc
	    doc-string]

	Notice the line break after '#:command-class' and after '#:doc',
	neither of which are ideal.  And so, for the two commands I am
	changing in this commit, I have made use of @w{...} to prevent line
	breaks between the keyword-name and the argument-name.  Now the pdf
	looks like this:

	  make-command name [#:invoke invoke]
	    [#:command-class command-class] [#:completer-class completer]
	    [#:prefix? prefix] [#:doc doc-string]

	Which seems much better.  I'll probably update the other deffn lines
	at some point.

	Update the default ISA spec from 2.2 to 20191213 will change the default

	Use target_announce_detach in more targets
	target_announce_detach was added in commit 0f48b757 ("Factor out
	"Detaching from program" message printing").  There, Pedro wrote:

	    (For now, I left the couple targets that print this a bit differently
	    alone.  Maybe this could be further pulled out into infcmd.c.  If we
	    did that, and those targets want to continue printing differently,
	    this new function could be converted to a target method.)

	It seems to me that the differences aren't very big, and in some cases
	other targets handled the output a bit more nicely.  In particular,
	some targets will print a different message when exec_file==NULL,
	rather than printing the same output with an empty string as
	exec_file.

	This patch incorporates the nicer output into target_announce_detach,
	then changes the remaining ports to use this function.

2022-01-06  Tom Tromey  <tom@tromey.com>

	Introduce target_announce_attach
	This introduces target_announce_attach, by analog with

	gdb: make use add_setshow_prefix_cmd in gnu-nat.c
	In gnu-nat.c we currently implement some set/show prefix commands
	"manually", that is, we call add_prefix_cmd, and assign a set and show
	function to each prefix command.

	These set/show functions print an error indicating that the user
	didn't type a complete command.

	If we instead switch to using add_setshow_prefix_cmd then we can
	delete the set/show functions, GDB provides some default functions,
	which give a nice help style summary that lists all of the available
	sub-commands, along with a one line summary of what each does.

	Though this clearly changes the existing behaviour, I think this
	change is acceptable as the new behaviour is more inline with other
	set/show prefix commands, and the new behaviour is more informative.

	This change will conflict with Tom's change here:

	  https://sourceware.org/pipermail/gdb-patches/2022-January/184724.html

	Where Tom changes the set/show functions that I delete.  My suggestion
	is that the set/show functions still be deleted even after Tom's
	patch (or instead of Tom's patch).

	For testing I've build GDB on GNU/Hurd, and manually tested these
	functions.  I did a grep over the testsuite, and don't believe the
	existing error messages are being checked for in any tests.

	Clean up some dead code in windows-tdep.c
	windows-tdep.c checks the result of xmalloc, which isn't necessary.  I
	initially removed this dead check, but then went a bit further and
	modified the code so that some "goto"s and explicit memory management
	could be removed.  Then, I added a couple of missing bounds checks.

	I believe this also fixes a possible bug with a missing 0-termination
	of a string.  I am not certain, but that is why I think the existing
	code allocates a buffer that is 1 byte too long -- but then it fails
	to set this byte to 0.

	Avoid crash in language_info

	x86: drop NoAVX insn attribute
	To avoid issues like that addressed by 6e3e5c9e4181 ("x86: extend SSE
	check to PCLMULQDQ, AES, and GFNI insns"), base the check on opcode
	attributes and operand types.

	x86: drop NoAVX from POPCNT
	With the introduction of CpuPOPCNT the NoAVX attribute has become
	meaningless for POPCNT.

	x86: drop some "comm" template parameters
	As already indicated in a remark when introducing these templates, the
	"commutative" attribute is ignored for legacy encoding templates. Hence
	it is possible to shorten a number of templates by specifying C directly
	rather than through a template parameter. I think this helps readability

	Change riscv_return_value to use RETURN_VALUE_ABI_PRESERVES_ADDRESS
	Internally, AdaCore has a test that is equivalent to (really a direct
	translation of) gdb.base/gnu_vector.exp.  On 32-bit RISC-V, the
	"return" part of this test fails.

	Joel tracked this down to riscv_return_value returning
	RETURN_VALUE_ABI_RETURNS_ADDRESS.  Using
	RETURN_VALUE_ABI_PRESERVES_ADDRESS is more correct here, and fixes the
	bug.

	I tested this for both 32- and 64-bit RISC-V using the AdaCore
	internal test suite, and Andrew Burgess tested it using
	gnu_vector.exp.

	Filtered output cleanup in expression dumping
	Most of the expression-dumping code uses filtered output, but a few
	functions did not.  This patch cleans up these instance.

	Note that this won't cause any behavior change, because the only calls
	to dump_prefix_expression pass in gdb_stdlog.  However, in the long
	run it's easier to audit the code if the number of uses of _unfiltered
	is reduced.

	Use filtered output in terminal_info implementations
	This changes one terminal_info implementation, and
	default_terminal_info, to use filtered output.  Other implementations
	of this method already use filtered output.

	I can't compile go32-nat.c, so this is a 'best effort' patch.

2022-01-05  Tom Tromey  <tom@tromey.com>

	Use filtered output in gnu-nat.c commands
	gnu-nat.c has a number of ordinary commands that should use filtered
	output.  In a few cases, I changed the output to use gdb_stderr as
	well.  I can't compile this file, so this patch is split out as a
	"best effort".

	Use filtered output in *-tdep commands
	Various targets introduce their own commands, which then use
	unfiltered output.  It's better to use filtered output by default, so
	this patch fixes the instances I found.

	Use filtered output in btrace-related commands
	This changes btrace.c and record-btrace.c to use filtered output in
	the commands implemented there.

	Use filtered output in some dumping commands
	There are several commands that may optionally send their output to a
	file -- they take an optional filename argument and open a file.  This
	patch changes these commands to use filtered output.  The rationale
	here is that, when printing to gdb_stdout, filtering is appropriate --
	it is, and should be, the default for all commands.  And, when writing
	to a file, paging will not happen anyway (it only happens when the
	stream==gdb_stdout), so using the _filtered form will not change
	anything.

	Use filtered output in kill command
	This changes the kill command to use filtered output.  I split this
	one into its own patch because, out of an abundance of caution, I
	changed the function to call bfd_cache_close_all a bit earlier, in
	case pagination caused an exception.

	Use filtered output in ordinary commands
	Many otherwise ordinary commands choose to use unfiltered output
	rather than filtered.  I don't think there's any reason for this, so
	this changes many such commands to use filtered output instead.

	Note that complete_command is not touched due to a comment there
	explaining why unfiltered output is believed to be used.

2022-01-05  Tom Tromey  <tom@tromey.com>

	Use filtered output in language_info
	Change language_info to use filtered output.  This is ok because the
	sole caller uses filtered output elsewhere, and because this function
	calls show_language_command, which also uses filtered output.

	Use filtered output in files_info implementations
	This changes the implementations of the target files_info method to
	use filtered output.  This makes sense because the sole caller of this
	method is an ordinary command (info_program_command).  This patch
	changes this command to use filtered output as well.

	Use filtered output in target-descriptions.c
	target-descriptions.c uses unfiltered output.  However, if you happen
	to invoke this command interactively, it's probably better for it to
	use filtering.  For non-interactive use, this doesn't matter.

	Use filtered output for gdbarch dump
	This changes gdbarch dumping to use filtered output.  This seems a bit
	better to me, both on the principle that this is an ordinary command,
	and because the output can be voluminous, so it may be nice to stop in
	the middle.

	Implement putstr and putstrn in ui_file
	In my tour of the ui_file subsystem, I found that fputstr and fputstrn
	can be simplified.  The _filtered forms are never used (and IMO
	unlikely to ever be used) and so can be removed.  And, the interface
	can be simplified by removing a callback function and moving the
	implementation directly to ui_file.

	A new self-test is included.  Previously, I think nothing was testing
	this code.

	Change how versioned symbols are recorded
	A change to BFD caused a gdb regression when using the Ada "catch
	exception" feature.  The bug is visible when a shared library throws
	an exception that is caught in the main executable.

	This was discussed here:

	https://sourceware.org/pipermail/binutils/2021-July/117538.html

	This patch implements Alan's proposed fix, namely to use VERSYM_HIDDEN
	rather than the name when deciding to install a version-less symbol.

	The internal test case is identical to the catch_ex_std.exp that is
	in-tree, so I haven't added a new test.  I could not make that one
	fail on x86-64 Linux, though.  It's possible that maybe I'd have to
	update the system linker first, but I didn't want to try that.

	Do not print anything when self-backtrace unavailable
	Right now, gdb's self-backtrace feature will still print something
	when a backtrace is unavailable:

	   sig_write (_("----- Backtrace -----\n"));
	[...]
	     sig_write (_("Backtrace unavailable\n"));
	    sig_write ("---------------------\n");

	However, if GDB_PRINT_INTERNAL_BACKTRACE is undefined, it seems better
	to me to print nothing at all.

	This patch implements this change.  It also makes a couple of other
	small changes in this same module: it adds a header guard to
	bt-utils.h, and it protects the definitions of
	gdb_internal_backtrace_1 with a check of GDB_PRINT_INTERNAL_BACKTRACE.

2022-01-05  Tom Tromey  <tromey@adacore.com>

	Fix pager regression
	The patch to fix paging with redirection caused a regression in the
	internal AdaCore test suite.  The problem occurs when running an MI
	command from the CLI using interpreter-exec, when paging is enabled.
	This scenario isn't covered by the current test suite, so this patch
	includes a new test.

	The problem is that, in this situation, MI does:

	  fputs_unfiltered (strcmp (context->command, "target-select") == 0
			     ? "^connected" : "^done", mi->raw_stdout);

	Here raw_stdout is a stdio_file wrapping stdout, so the pager thinks
	that it is ok to buffer the output.  However, in this setup, it isn't
	ok, and flushing the wrap buffer doesn't really work properly.  Also,
	MI next does:

	  mi_out_put (uiout, mi->raw_stdout);

	... but this uses ui_file::write, which also doesn't flush the wrap
	buffer.

	I think all this will be fixed by the pager rewrite series I'm working
	on.  However, in the meantime, adding the old gdb_stdout check back to
	the pager fixes this problem.

	Regression tested on x86-64 Fedora 34.

	elf: Set p_align to the minimum page size if possible
	Currently, on 32-bit and 64-bit ARM, it seems that ld generates p_align
	values of 0x10000 even if no section alignment is greater than 0x1000.
	The issue is more general and probably affects other targets with multiple
	page sizes.

	While file layout absolutely must take 64K page size into account, that
	does not have to be reflected in the p_align value.  If running on a 64K
	kernel, the file will be loaded at a 64K page boundary by necessity. On
	a 4K kernel, 64K alignment is not needed.

	The glibc loader has been fixed to honor p_align:

	https://sourceware.org/bugzilla/show_bug.cgi?id=28676

	similar to kernel:

	commit ce81bb256a224259ab686742a6284930cbe4f1fa
	Author: Chris Kennelly <ckennelly@google.com>
	Date:   Thu Oct 15 20:12:32 2020 -0700

	    fs/binfmt_elf: use PT_LOAD p_align values for suitable start address

	This means that on 4K kernels, we will start to do extra work for 64K
	p_align, but this pointless for pretty much all binaries (whose section
	alignment rarely exceeds 16).

	The minimum page size is used, instead of the maximum section alignment
	due to this glibc bug:

	https://sourceware.org/bugzilla/show_bug.cgi?id=28688

	It has been fixed in glibc 2.35.  But linker output must work on existing
	glibc binaries.

	1. Set p_align to the minimum page size while laying out segments aligning
	to the maximum page size or section alignment.  The run-time loader can
	align segments to the minimum page size or above, depending on system page
	size.
	2. If -z max-page-size=NNN is used, p_align will be set to the maximum
	page size or the largest section alignment.
	3. If a section requires alignment higher than the minimum page size,
	don't set p_align to the minimum page size.
	4. If a section requires alignment higher than the maximum page size,
	set p_align to the section alignment.
	5. For objcopy, when the minimum page size != the maximum page size,
	p_align may be set to the minimum page size while segments are aligned
	to the maximum page size.  In this case, the input p_align will be
	ignored and the maximum page size will be used to align the ouput
	segments.
	6. Update linker to disallow the common page size > the maximum page size.
	7. Update linker to avoid the common page size > the maximum page size.
	8. Adjust pru_irq_map-1.d to expect p_align == sh_addralign:

	003aae076207dbf32f98ba846158fc32669ef85f (gdb: Copy inferior properties

	    FAIL: gdb.base/inferior-clone.exp: inferior 2: clone-inferior

	The error is as follows:

	    Added inferior 2 on connection 1 (extended-remote localhost:2346)
	    (gdb) FAIL: gdb.base/inferior-clone.exp: inferior 2: clone-inferior

	This fails because the testcase only expect the 'Added inferior 2' part

	gdb: don't pass nullptr to sigwait
	I tried building GDB on GNU/Hurd, and ran into this warning:

	  gdbsupport/scoped_ignore_signal.h:78:16: error: null argument where non-null required (argument 2) [-Werror=nonnull]

	This is because in this commit:

	  commit 99624310dd82542c389c89c2e55d8cae36bb74e1
	  Date:   Sun Jun 27 15:13:14 2021 -0400

	      gdb: fall back on sigpending + sigwait if sigtimedwait is not available

	A call to sigwait was introduced that passes nullptr as the second
	argument, this call is only reached if sigtimedwait is not supported.

	The original patch was written for macOS, I assume on that target
	passing nullptr as the second argument is fine.

	On my GNU/Linux box, the man-page for sigwait doesn't mention that
	nullptr is allowed for the second argument, so my assumption would be
	that nullptr is not OK, and, if I change the '#ifdef
	HAVE_SIGTIMEDWAIT' introduced by the above patch to '#if 0', and
	rebuild on GNU/Linux, I see the same warning that I see on GNU/Hurd.

	I propose that we stop passing nullptr as the second argument to
	sigwait, and instead pass a valid int pointer.  The value returned in
	the int can then be used in an assert.

	For testing, I (locally) made the change to the #ifdef I mentioned
	above, compiled GDB, and ran the usual tests, this meant I was using
	sigwait instead on sigtimedwait on GNU/Linux, I saw no regressions.

	x86/Intel: correct VFPCLASSP{S,D} handling when displacement is present
	fits_in_disp8() can be called before ambiguous operands get resolved
	or rejected (in process_suffix()), which requires that i.memshift be
	non-negative to avoid an internal error. This case wasn't covered by
	6c0946d0d28d ("x86: correct VFPCLASSP{S,D} operand size handling").

	gas: rework handling of backslashes in quoted symbol names
	Strange effects can result from the present handling, e.g.:

	.if 1
	"backslash\\":
	.endif

	yields first (correctly) "missing closing `"'" but then also "invalid
	character '\' in mnemonic" and further "end of file inside conditional".
	Symbols names ending in \ are in principle not expressable with that
	scheme.

	Instead of recording whether a backslash was seen, inspect the
	subsequent character right away. Only accept \\ (meaning a single
	backslash in the resulting symbol name) and \" (meaning an embedded
	double quote in the resulting symbol name) for now, warning about any
	other combination.

	While perhaps not necessary immediately, also permit concatenated
	strings to form a symbol name. This may become useful if going forward
	we would want to support \<octal> or \x<hex> sequences, where closing
	and re-opening quotes can be useful to delimit such sequences.

	The ELF "Multibyte symbol names" test gets switched away from using
	.set, as that would now also mean excluding nios2 and pru. By using
	.equiv instead, even the existing #notarget can be dropped. (For h8300
	the .section directive additionally needs attributes specified, to avoid
	a target specific warning.)

	[gdb/cli] Improve show logging output
	Before commit 3b6acaee895 "Update more calls to add_prefix_cmd" we had the
	following output for "show logging":
	...
	$ gdb -q -batch -ex "set trace-commands on" \
	    -ex "set logging off" \
	    -ex "show logging" \
	    -ex "set logging on" \
	    -ex "show logging"
	+set logging off
	+show logging
	Future logs will be written to gdb.txt.
	Logs will be appended to the log file.
	Output will be logged and displayed.
	Debug output will be logged and displayed.
	+set logging on
	+show logging
	Currently logging to "gdb.txt".
	Logs will be appended to the log file.
	Output will be logged and displayed.
	Debug output will be logged and displayed.
	...

	After that commit we have instead:
	...
	+set logging off
	+show logging
	debugredirect:  The logging output mode is off.
	file:  The current logfile is "gdb.txt".
	overwrite:  Whether logging overwrites or appends to the log file is off.
	redirect:  The logging output mode is off.
	+set logging on
	+show logging
	debugredirect:  The logging output mode is off.
	file:  The current logfile is "gdb.txt".
	overwrite:  Whether logging overwrites or appends to the log file is off.
	redirect:  The logging output mode is off.
	...
	which gives less clear output for some subcommands.

	OTOH, it's explicit about whether boolean values are on or off.

	The new text seems to have been chosen to match the set/show help texts:
	...
	(gdb) help show logging
	Show logging options.

	List of show logging subcommands:

	show logging debugredirect -- Show the logging debug output mode.
	show logging file -- Show the current logfile.
	show logging overwrite -- \
	  Show whether logging overwrites or appends to the log file.
	show logging redirect -- Show the logging output mode.
	...

	Make the show logging messages more clear, while still keep the boolean
	values explicit, such that we have:
	...
	$ ./gdb.sh -q -batch -ex "show logging"
	logging debugredirect:  off: \
	  Debug output will go to both the screen and the log file.
	logging enabled:  off: Logging is disabled.
	logging file:  The current logfile is "gdb.txt".
	logging overwrite:  off: Logging appends to the log file.
	logging redirect:  off: Output will go to both the screen and the log file.
	...

	Fix use of 'printf' in gdbtypes.c
	An earlier patch of mine, commit 64b7cc50 ("Remove
	gdb_print_host_address") inadvertently changed a function in
	gdbtypes.c to use printf rather than printf_filtered.  This patch
	fixes the problem.

	Fix regression in page-logging.exp
	Simon and Tom pointed out that page-logging.exp failed on their
	machines.  Tom tracked this down to the "width" setting.  Since
	there's no need in the test to change the width, it seems simplest to
	remove the setting.  I confirmed that the test still fails if the fix
	is backed out, ensuring that the test is still testing what it
	purports to.

	Small indentation fix in eval.c
	I noticed that the AdaCore tree had a small divergence in eval.c -- it
	had a fix for an indentation problem in binop_promote.  I'm checking
	in this small fix as obvious.

	[gdb/testsuite] Handle for loop initial decl with gcc 4.8.5
	When running test-case gdb.threads/schedlock-thread-exit.exp on a system with

	...
	src/gdb/testsuite/gdb.threads/schedlock-thread-exit.c:33:3: error: \
	  'for' loop initial declarations are only allowed in C99 mode
	...

	Fix this by:
	- using -std=c99, or
	- using -std=gnu99, in case that's required, or
	- in the case of the jit test-cases, rewriting the for loops.

	Tested on x86_64-linux, both with gcc 4.8.5 and gcc 7.5.0.

	Use correct stream for process record output
	The process record code often emits unfiltered output.  In some cases,

	Note that in many cases, the output to stderr is followed by a
	"return -1", which is how process record indicates an error.  It seems
	to me that calling error here would be preferable, because, in many

	gdbtypes.h uses core_addr_eq and core_addr_hash in a weird way: taking

	It seems better to simply inline the ordinary code here.  CORE_ADDR is
	a scalar so it can be directly compared, and the identity hash

	gdb: Copy inferior properties in clone-inferior
	This commit ensures that the following settings are cloned from one
	inferior to the new one when processing the clone-inferior command:
	  - inferior-tty
	  - environment variables
	  - cwd
	  - args

	Some of those parameters can be passed as command line arguments to GDB
	(-args and -tty), so one could expect the clone-inferior to respect
	those flags.  The following debugging session illustrates that:

	    gdb -nx -quiet -batch \
	         -ex "show args" \
	         -ex "show inferior-tty" \
	         -ex "clone-inferior" \
	         -ex "inferior 2" \
	         -ex "show args" \
	         -ex "show inferior-tty" \
	         -tty=/some/tty \
	         -args echo foo bar
	    Argument list to give program being debugged when it is started is "foo bar".
	    Terminal for future runs of program being debugged is "/some/tty".
	    [New inferior 2]
	    Added inferior 2.
	    [Switching to inferior 2 [<null>] (/bin/echo)]
	    Argument list to give program being debugged when it is started is "".
	    Terminal for future runs of program being debugged is "".

	The other properties this commit copies on clone (i.e. CWD and the
	environment variables) are included since they are related (in the sense
	that they influence the runtime behavior of the program) even if they
	cannot be directly set using command line switches.

	There is a chance that this patch changes existing user workflow.  I
	think that this change is mostly harmless.  If users want to start a new
	inferior based on an existing one, they probably already propagate those

	gdb/remote: handle attach when stop packet lacks thread-id
	Bug PR gdb/28405 reports a regression when using attach with an
	extended-remote target.  In this case the target is not including a
	thread-id in the stop packet it sends back after the attach.

	The regression was introduced with this commit:

	  commit 8f66807b98f7634c43149ea62e454ea8f877691d
	  Date:   Wed Jan 13 20:26:58 2021 -0500

	      gdb: better handling of 'S' packets

	The problem is that when GDB processes the stop packet, it sees that
	there is no thread-id and so has to "guess" which thread the stop
	should apply to.

	In this case the target only has one thread, so really, there's no
	guessing needed, but GDB still runs through the same process, this
	shouldn't cause us any problems.

	However, after the above commit, GDB now expects itself to be more
	internally consistent, specifically, only a thread that GDB thinks is
	resumed, can be a candidate for having stopped.

	It turns out that, when GDB attaches to a process through an
	extended-remote target, the threads of the process being attached too,
	are not, initially, marked as resumed.

	And so, when GDB tries to figure out which thread the stop might apply
	too, it finds no threads in the processes marked resumed, and so an
	assert triggers.

	In extended_remote_target::attach we create a new thread with a call
	to add_thread_silent, rather than remote_target::remote_add_thread,
	the reason is that calling the latter will result in a call to
	'add_thread' rather than 'add_thread_silent'.  However,
	remote_target::remote_add_thread includes additional
	actions (i.e. calling remote_thread_info::set_resumed and set_running)
	which are missing from extended_remote_target::attach.  These missing
	calls are what would serve to mark the new thread as resumed.

	In this commit I propose that we add an extra parameter to
	remote_target::remote_add_thread.  This new parameter will force the
	new thread to be added with a call to add_thread_silent.  We can now
	call remote_add_thread from the ::attach method, the extra
	actions (listed above) will now be performed, and the thread will be
	left in the correct state.

	Additionally, in PR gdb/28405, a segfault is reported.  This segfault
	triggers when 'set debug remote 1' is used before trying to reproduce
	the original assertion failure.  The cause of this is in
	remote_target::select_thread_for_ambiguous_stop_reply, where we do
	this:

	  remote_debug_printf ("first resumed thread is %s",
			       pid_to_str (first_resumed_thread->ptid).c_str ());
	  remote_debug_printf ("is this guess ambiguous? = %d", ambiguous);

	  gdb_assert (first_resumed_thread != nullptr);

	Notice that when debug printing is on we dereference
	first_resumed_thread before we assert that the pointer is not
	nullptr.  This is the cause of the segfault, and is resolved by moving
	the assert before the debug printing code.

	I've extended an existing test, ext-attach.exp, so that the original
	test is run multiple times; we run in the original mode, as normal,
	but also, we now run with different packets disabled in gdbserver.  In
	particular, disabling Tthread would trigger the assertion as it was
	reported in the original bug.  I also run the test in all-stop and
	non-stop modes now for extra coverage, we also run the tests with
	target-async enabled, and disabled.

	gdb: on x86-64 non-trivial C++ objects are returned in memory
	Fixes PR gdb/28681.  It was observed that after using the `finish`
	command an incorrect value was displayed in some cases.  Specifically,
	this behaviour was observed on an x86-64 target.

	Consider this test program:

	  struct A
	  {
	    int i;

	    A ()
	    { this->i = 0; }
	    A (const A& a)
	    { this->i = a.i; }
	  };

	  A
	  func (int i)
	  {
	    A a;
	    a.i = i;
	    return a;
	  }

	  int
	  main ()
	  {
	    A a = func (3);
	    return a.i;
	  }

	And this GDB session:

	  $ gdb -q ex.x
	  Reading symbols from ex.x...
	  (gdb) b func
	  Breakpoint 1 at 0x401115: file ex.cc, line 14.
	  (gdb) r
	  Starting program: /home/andrew/tmp/ex.x

	  Breakpoint 1, func (i=3) at ex.cc:14
	  14	  A a;
	  (gdb) finish
	  Run till exit from #0  func (i=3) at ex.cc:14
	  main () at ex.cc:23
	  23	  return a.i;
	  Value returned is $1 = {
	    i = -19044
	  }
	  (gdb) p a
	  $2 = {
	    i = 3
	  }
	  (gdb)

	Notice how after the `finish` the contents of $1 are junk, but, when I
	immediately ask for the value of `a`, I get back the correct value.

	The problem here is that after the finish command GDB calls the
	function amd64_return_value to figure out where the return value can
	be found (on x86-64 targets anyway).

	This function makes the wrong choice for the struct A in our case, as
	sizeof(A) <= 8, then amd64_return_value decides that A will be
	returned in a register.  GDB then reads the return value register an
	interprets the contents as an instance of A.

	Unfortunately, A is not trivially copyable (due to its copy
	constructor), and the sys-v specification for argument and return
	value passing, says that any non-trivial C++ object should have space
	allocated for it by the caller, and the address of this space is
	passed to the callee as a hidden first argument.  The callee should
	then return the address of this space as the return value.

	And so, the register that GDB is treating as containing an instance of
	A, actually contains the address of an instance of A (in this case on
	the stack), this is why GDB shows the incorrect result.

	The call stack within GDB for where we actually go wrong is this:

	  amd64_return_value
	    amd64_classify
	      amd64_classify_aggregate

	And it is in amd64_classify_aggregate that we should be classifying
	the type as AMD64_MEMORY, instead of as AMD64_INTEGER as we currently
	do (via a call to amd64_classify_aggregate_field).

	At the top of amd64_classify_aggregate we already have this logic:

	  if (TYPE_LENGTH (type) > 16 || amd64_has_unaligned_fields (type))
	    {
	      theclass[0] = theclass[1] = AMD64_MEMORY;
	      return;
	    }

	Which handles some easy cases where we know a struct will be placed
	into memory, that is (a) the struct is more than 16-bytes in size,
	or (b) the struct has any unaligned fields.

	All we need then, is to add a check here to see if the struct is
	trivially copyable.  If it is not then we know the struct will be
	passed in memory.

	I originally structured the code like this:

	  if (TYPE_LENGTH (type) > 16
	      || amd64_has_unaligned_fields (type)
	      || !language_pass_by_reference (type).trivially_copyable)
	    {
	      theclass[0] = theclass[1] = AMD64_MEMORY;
	      return;
	    }

	This solved the example from the bug, and my small example above.  So
	then I started adding some more extensive tests to the GDB testsuite,
	and I ran into a problem.  I hit this error:

	  gdbtypes.h:676: internal-error: loc_bitpos: Assertion `m_loc_kind == FIELD_LOC_KIND_BITPOS' failed.

	This problem is triggered from:

	  amd64_classify_aggregate
	    amd64_has_unaligned_fields
	      field::loc_bitpos

	Inside the unaligned field check we try to get the bit position of
	each field.  Unfortunately, in some cases the field location is not
	FIELD_LOC_KIND_BITPOS, but is FIELD_LOC_KIND_DWARF_BLOCK.

	An example that shows this bug is:

	  struct B
	  {
	    short j;
	  };

	  struct A : virtual public B
	  {
	    short i;

	    A ()
	    { this->i = 0; }
	    A (const A& a)
	    { this->i = a.i; }
	  };

	  A
	  func (int i)
	  {
	    A a;
	    a.i = i;
	    return a;
	  }

	  int
	  main ()
	  {
	    A a = func (3);
	    return a.i;
	  }

	It is the virtual base class, B, that causes the problem.  The base
	class is represented, within GDB, as a field within A.  However, the
	location type for this field is a DWARF_BLOCK.

	I spent a little time trying to figure out how to convert the
	DWARF_BLOCK to a BITPOS, however, I realised that, in this case at
	least, conversion is not needed.

	The C++ standard says that a class is not trivially copyable if it has
	any virtual base classes.  And so, in this case, even if I could
	figure out the BITPOS for the virtual base class fields, I know for
	sure that I would immediately fail the trivially_copyable check.  So,
	lets just reorder the checks in amd64_classify_aggregate to:

	  if (TYPE_LENGTH (type) > 16
	      || !language_pass_by_reference (type).trivially_copyable
	      || amd64_has_unaligned_fields (type))
	    {
	      theclass[0] = theclass[1] = AMD64_MEMORY;
	      return;
	    }

	Now, if we have a class with virtual bases we will fail quicker, and
	avoid the unaligned fields check completely.

	gdb: make use of SCOPE_EXIT to manage thread executing state
	While working on another patch relating to how GDB manages threads
	executing and resumed state, I spotted the following code in
	record-btrace.c:

	  executing = tp->executing ();
	  set_executing (proc_target, inferior_ptid, false);

	  id = null_frame_id;
	  try
	    {
	      id = get_frame_id (get_current_frame ());
	    }
	  catch (const gdb_exception &except)
	    {
	      /* Restore the previous execution state.  */
	      set_executing (proc_target, inferior_ptid, executing);

	      throw;
	    }

	  /* Restore the previous execution state.  */
	  set_executing (proc_target, inferior_ptid, executing);

	  return id;

	I notice that we only catch the exception so we can call
	set_executing, and this is the same call to set_executing that we need
	to perform in the non-exception return path.

	This would be much cleaner if we could use SCOPE_EXIT to avoid the
	try/catch, so lets do that.

	While cleaning this up, I also applied a similar patch to
	record-full.c, though there's no try/catch in that case, but using
	SCOPE_EXIT makes the code safe if, in the future, we do start throwing
	exceptions.

	There should be no user visible changes after this commit.

	gdb/doc: add some index entries relating to mi-async setting
	I noticed that the mi-async setting was not referenced from the index
	in any way, this commit tries to rectify that a bit.

	The @cindex lines I think are not controversial, these same index
	entries are used elsewhere in the manual for async related topics (see
	@node Background Execution).

	The only bit that might be controversial is that I've added a @kindex
	entry for 'set mi-async' when the command is documented as '-gdb-set
	mi-async' (with a similar difference for the show/-gdb-show).

	My reasoning here is that nothing else is indexed under -gdb-set or
	-gdb-show, and as -gdb-set/-gdb-show are just the MI equivalent for
	set/show anything that is documented under set/show can be adjusted
	using -gdb-set/-gdbshow, and so, I've tried to keep the index
	consistent for mi-async.

	gdb: add threads debugging switch
	Add new commands:

	Prints additional debug information relating to thread creation and

	GDB already announces when threads are created of course.... most of
	the time, but sometimes threads are added silently, in which case this
	debug message is the only mechanism to see the thread being added.
	Also, though GDB does announce when a thread exits, it doesn't
	announce when the thread object is deleted, I've added a debug message
	for that.

	Additionally, having message printed through the debug system will
	cause the messages to be nested to an appropriate depth when other

	gdb: add assert in remote_target::wait relating to async being off
	While working on another patch I ended up in a situation where I had
	async mode disabled (with 'maint set target-async off'), but the async
	event token got marked anyway.

	In this situation GDB was continually calling into
	remote_target::wait, however, the async token would never become
	unmarked as the unmarking is guarded by target_is_async_p.

	We could just unconditionally unmark the token, but that would feel
	like just ignoring a bug, so, instead, lets assert that if
	!target_is_async_p, then the async token should not be marked.

	This assertion would have caught my earlier mistake.

	There should be no user visible changes with this commit.

2021-12-18  Andrew Burgess  <aburgess@redhat.com>

	gdb/remote: some fixes for 'maint set target-async off'
	While working on another patch relating to remote targets, I wanted to
	test with 'maint set target-async off' in place.  Unfortunately I ran
	into some problems.  This commit is an attempt to fix one of the
	issues I hit.

	In my particular case I was actually running with:

	  maint set target-async off
	  maint set target-non-stop off

	that is, we're telling GDB to force the targets to operate in
	non-async mode, and in all-stop mode.  Here's my GDB session showing
	the problem:

	  (gdb) maintenance set target-async off
	  (gdb) maintenance set target-non-stop off
	  (gdb) target extended-remote :54321
	  Remote debugging using :54321
	  (gdb) attach 2365960
	  Attaching to process 2365960
	  No unwaited-for children left.
	  (gdb)

	Notice the 'No unwaited-for children left.' error, this is the
	problem.  There's no reason why GDB should not be able to attach to
	the process.

	The problem is this:

	  1. The user runs 'attach PID' and this sends GDB into attach_command
	  in infcmd.c.  From here we call the ::attach method on the attach
	  target, which will be the extended_remote_target.

	  2. In extended_remote_target::attach, we attach to the remote target
	  and get the first reply (which is a stop packet).  We put off
	  processing the stop packet until the end of ::attach.  We setup the
	  inferior and thread to represent the process we attached to, and
	  download the target description.  Finally, we process the initial
	  stop packet.

	  If '!target_is_non_stop_p ()' and '!target_can_async_p ()', which is
	  the case for us given the maintenance commands we used, we cache the
	  stop packet within the remote_state::buf for later processing.

	  3. Back in attach_command, if 'target_is_non_stop_p ()' then we
	  request that the target stops.  This will either process any cached
	  stop replies, or request that the target stops, and process the stop
	  replies.  However, this code is not what we use due to non-stop mode
	  being disabled.  So, we skip to the next step which is to call
	  validate_exec_file.

	  4. Calling validate_exec_file can cause packets to be sent to the
	  remote target, and replies received, the first path I hit is the
	  call to target_pid_to_exec_file, which calls
	  remote_target::pid_to_exec_file, which can then try to read the
	  executable from the remote.  Sending an receiving packets will make
	  use of the remote_state::buf object.

	  5. The attempt to attach continues, but the damage is already done...

	So, the problem is that, in step #2 we cache a stop reply in the
	remote_state::buf, and then in step #4 we reuse the remote_state::buf
	object, discarding any cached stop reply.  As a result, the initial
	stop, which is sent when GDB first attaches to the target, is lost.

	This problem can clearly be seen, I feel, by looking at the
	remote_state::cached_wait_status flag.  This flag tells GDB if there
	is a wait status cached in remote_state::buf.  However, in
	remote_target::putpkt_binary and remote_target::getpkt_or_notif_sane_1
	this flag is just set back to 0, doing this immediately discards any
	cached data.

	I don't know if this scheme ever made sense,  looking at commit
	2d717e4f8a54, where the cached_wait_status flag was added, it appears
	that there was nothing between where the stop was cached, and where
	the stop was consumed, so, I suspect, there never was a situation
	where we ended up in putpkt_binary or getpkt_or_notif_sane_1 and
	needed to clear to the flag, maybe the clearing was added "just in
	case".  Whatever the history, I claim that this clearing this flag is
	no longer a good idea.

	So, my first step toward fixing this issue was to replace the two
	instances of 'rs->cached_wait_status = 0;' in ::putpkt_binary and
	::getpkt_or_notif_sane_1 with 'gdb_assert (rs->cached_wait_status ==
	0);', this, at least would show me when GDB was doing something
	dangerous, and indeed, this assert is now hit in my test case above.

	I did play with using some kind of scoped restore to backup, and
	restore the remote_state::buf object in all the places within remote.c
	that I was hitting where the ::buf was being corrupted.  The first
	problem with this is that, where the ::cached_wait_status flag is
	reset is _not_ where ::buf is corrupted.  For the ::putpkt_binary
	case, by the time we get to the method the buffer has already been
	corrupted in many cases, so we end up needing to add the scoped
	save/restore within the callers, which means we need the save/restore
	in _lots_ of places.

	Plus, using this save/restore model feels like the wrong solution.  I
	don't think that it's obvious that the buffer might be holding cached
	data, and I think it would be too easy for new corruptions of the
	buffer to be introduced, which could easily go unnoticed for a long
	time.

	So, I really wanted a solution that didn't require us to cache data in
	the ::buf object.

	Luckily, I think we already have such a solution in place, the
	remote_state::stop_reply_queue, it seems like this does exactly the
	same task, just in a slightly different way.  With the
	::stop_reply_queue, the stop packets are processed upon receipt and
	the stop_reply object is added to the queue.  With the ::buf cache
	solution, the unprocessed stop reply is cached in the ::buf, and
	processed later.

	So, finally, in this commit, I propose to remove the
	remote_state::cached_wait_status flag and to stop using the ::buf to
	cache stop replies.  Instead, stop replies will now always be stored
	in the ::stop_reply_queue.

	There are two places where we use the ::buf to hold a cached stop
	reply, the first is in the ::attach method, and the second is in
	remote_target::start_remote, however, the second of these cases is far
	less problematic, as after caching the stop reply in ::buf we call the
	global start_remote function, which does very little work before
	calling normal_stop, which processes the cached stop reply.  However,
	my plan is to switch both users over to using ::stop_reply_queue so
	that the old (unsafe) ::cached_wait_status mechanism can be completely
	removed.

	The next problem is that the ::stop_reply_queue is currently only used
	for async-mode, and so, in remote_target::push_stop_reply, where we
	push stop_reply objects into the ::stop_reply_queue, we currently also
	mark the async event token.  I've modified this so we only mark the
	async event token if 'target_is_async_p ()' - note, _is_, not _can_
	here. The ::push_stop_reply method is called in places where async
	mode has been temporarily disabled, but, when async mode is switched
	back on (see remote_target::async) we will mark the event token if
	there are events in the queue.

	Another change of interest is in remote_target::remote_interrupt_as.
	Previously this code checked ::cached_wait_status, but didn't check
	for events in the ::stop_reply_queue.  Now that ::cached_wait_status
	has been removed we now check the queue length instead, which should
	have the same result.

	Finally, in remote_target::wait_as, I've tried to merge the processing
	of the ::stop_reply_queue with how we used to handle the
	::cached_wait_status flag.

	Currently, when processing the ::stop_reply_queue we call
	process_stop_reply and immediately return.  However, when handling
	::cached_wait_status we run through the whole of ::wait_as, and return
	at the end of the function.

	If we consider a standard stop packet, the two differences I see are:

	  1. Resetting of the remote_state::waiting_for_stop_reply, flag; this
	  is not currently done when processing a stop from the
	  ::stop_reply_queue.

	  2. The final return value has the possibility of being adjusted at
	  the end of ::wait_as, as well as there being calls to
	  record_currthread, non of which are done if we process a stop from
	  the ::stop_reply_queue.

	After discussion on the mailing list:

	  https://sourceware.org/pipermail/gdb-patches/2021-December/184535.html

	it was suggested that, when an event is pushed into the
	::stop_reply_queue, the ::waiting_for_stop_reply flag is never going
	to be set.  As a result, we don't need to worry about the first
	difference.  I have however, added a gdb_assert to validate the
	assumption that the flag is never going to be set.  If in future the
	situation ever changes, then we should find out pretty quickly.

	As for the second difference, I have resolved this by having all stop
	packets taken from the ::stop_reply_queue, pass through the return
	value adjustment code at the end of ::wait_as.

	An example of a test that reveals the benefits of this commit is:

	  make check-gdb \
	    RUNTESTFLAGS="--target_board=native-extended-gdbserver \
	                  GDBFLAGS='-ex maint\ set\ target-async\ off \
	                            -ex maint\ set\ target-non-stop\ off' \
	                  gdb.base/attach.exp"

	For testing I've been running test on x86-64/GNU Linux, and run with
	target boards unix, native-gdbserver, and native-extended-gdbserver.
	For each board I've run with the default GDBFLAGS, as well as with:

	  GDBFLAGS='-ex maint\ set\ target-async\ off \
	            -ex maint\ set\ target-non-stop\ off' \

	Though running with the above GDBFLAGS is clearly a lot more unstable
	both before and after my patch, I'm not seeing any consistent new
	failures with my patch, except, with the native-extended-gdbserver
	board, where I am seeing new failures, but only because more tests are
	now running.  For that configuration alone I see the number of
	unresolved go down by 49, the number of passes goes up by 446, and the
	number of failures also increases by 144.  All of the failures are new
	tests as far as I can tell.

	gdb/tui: install SIGWINCH only when connected to a TTY
	PR26056 reports that when GDB is connected to non-TTY stdin/stdout, it
	crashes when it receives a SIGWINCH signal.

	This can be reproduced as follows:

	    $ gdb/gdb -nx -batch -ex 'run' --args sleep 60 </dev/null 2>&1 | cat

	    # from another terminal:
	    $ kill -WINCH %(pidof gdb)

	When doing so, the process crashes in a call to rl_resize_terminal:

	    void
	    rl_resize_terminal (void)
	    {
	      _rl_get_screen_size (fileno (rl_instream), 1);
	      ...
	    }

	The problem is that at this point rl_instream has the value NULL.

	The rl_instream variable is supposed to be initialized during a call to
	readline_initialize_everything, which in a normal startup sequence is
	called under this call chain:

	    tui_interp::init
	      tui_ensure_readline_initialized
	        rl_initialize
	          readline_initialize_everything

	In tui_interp::init, we have the following sequence:

	    tui_initialize_io ();
	    tui_initialize_win ();                // <- Installs SIGWINCH
	    if (gdb_stdout->isatty ())
	      tui_ensure_readline_initialized (); // <- Initializes rl_instream

	This function unconditionally installs the SIGWINCH signal handler (this
	is done by tui_initialize_win), and then if gdb_stdout is a TTY it
	initializes readline.  Therefore, if stdout is not a TTY, SIGWINCH is
	installed but readline is not initialized.  In such situation
	rl_instream stays NULL, and when GDB receives a SIGWINCH it calls its
	handler and in fine tries to access rl_instream leading to the crash.

	This patch proposes to fix this issue by installing the SIGWINCH signal
	handler only if GDB is connected to a TTY.  Given that this
	initialization it the only task of tui_initialize_win, this patch moves
	tui_initialize_win just after the call to
	tui_ensure_readline_initialized.

	Tested on x86_64-linux.

	RISC-V: Support svinval extension with frozen version 1.0.
	According to the privileged spec, there are five new instructions for
	svinval extension.  Two of them (HINVAL.VVMA and HINVAL.GVMA) need to
	enable the hypervisor extension.  But there is no implementation of
	hypervisor extension in mainline for now, so let's consider the related
	issues later.

	This patch is cherry-picked from the riscv integration branch since the
	svinval extension is frozen for now.  Besides, we fix the funct7 encodings
	of hinval.vvma and hinval.gvma, from 0x0011011 and 0x0111011 to 0x0010011
	and 0x0110011.

	PR28691, validate dwarf attribute form
	PR28691 is a fuzzing PR that triggers a non-problem of "output changes
	per run" with PIEs and/or different compilers.  I've closed similar
	PRs before as wontfix, but I guess there will be no end of this type
	of PR.  The trigger is an attribute that usually takes one of the
	offset/constant reference DW_FORMs being given an indexed string
	DW_FORM.  The bfd reader doesn't support indexed strings and returns
	an error string instead.  The address of the string varies with PIE
	runs and/or compiler, and we allow that address to appear in output.

	New --enable-threading configure option to control use of threads in GDB/GDBserver
	Add the --enable-threading configure option so multithreading can be disabled
	at configure time. This is useful for statically-linked builds of
	GDB/GDBserver, since the thread library doesn't play well with that setup.

	If you try to run a statically-linked GDB built with threading, it will crash
	when setting up the number of worker threads.

	This new option is also convenient when debugging GDB in a system with lots of
	threads, where the thread discovery code in GDB will emit too many messages,
	like so:

	[New Thread 0xfffff74d3a50 (LWP 2625599)]

	Before that, snprintf would return a value bigger that UNIX_PATH_MAX and
	the "if" after would catch it and emit a warning, which is exactly what
	we want.  That change was done because LynxOS didn't have snprintf.
	Since LynxOS isn't supported anymore, we can simply revert to use
	snprintf there.

	With this patch, we get a warning (printed by the caller of
	gdb_agent_socket_init), but the program keeps executing:

	    $ LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libasan.so.6:./libinproctrace.so /bin/ls
	    ipa: could not create sync socket
	    ...

	From what I can see, we are copying from a static 108 bytes long buffer
	(the global array agent_socket_name) to a 108 bytes long array,
	sockaddr_un::sun_path.  I don't see anything wrong.

	Still, it would make things easier if we didn't see this error.  Change
	the code to check that the source string length is smaller than the
	destination buffer (including space for the NULL byte) and use strcpy.

	bfd: fix -Wunused errors with clang 13+
	Clang 13 and 14 produce some -Wunused-but-set-{variable,parameter} for
	situations where gcc doesn't.  In particular, when a variable is set and
	then used in a way to update its own value.  For example, if `i` is only
	used in this way:

	  int i = 2;
	  i++;
	  i = i + 1;

	gcc won't warn, but clang will.

	Fix all such errors found in an --enable-targets=all build.  It would be
	important for somebody who knows what they're doing to just make sure
	that these variables can indeed be deleted, and that there a no cases
	where it's a bug, and the variable should actually be used.

	The first instance of this error fix by this patch is:

	RISC-V: Added ld testcases for the medlow and medany code models.
	There are two linker scripts, code-model-01.ld and code-model-02.ld,

	gdb: improve reuse of value contents when fetching array elements
	While working on a Python script, which was interacting with a remote
	target, I noticed some weird slowness in GDB.  In my program I had a
	structure something like this:

	  struct foo_t
	  {
	    int array[5];
	  };

	  struct foo_t global_foo;

	Then in the Python script I was fetching a complete copy of global
	foo, like:

	  val = gdb.parse_and_eval('global_foo')
	  val.fetch_lazy()

	Then I would work with items in foo_t.array, like:

	  print(val['array'][1])

	I called the fetch_lazy method specifically because I knew I was going
	to end up accessing almost all of the contents of val, and so I wanted
	GDB to do a single remote protocol call to fetch all the contents in
	one go, rather than trying to do lazy fetches for a couple of bytes at
	a time.

	What I observed was that, after the fetch_lazy call, GDB does,
	correctly, fetch the entire contents of global_foo, including all of
	the contents of array, however, when I access val.array[1], GDB still
	goes and fetches the value of this element from the remote target.

	What's going on is that in valarith.c, in value_subscript, for C like
	languages, we always end up treating the array value as a pointer, and
	then doing value_ptradd, and value_ind, the second of these calls
	always returns a lazy value.

	My guess is that this approach allows us to handle indexing off the
	end of an array, when working with zero element arrays, or when
	indexing a raw pointer as an array.  And, I agree, that in these
	cases, where, even when the original value is non-lazy, we still will
	not have the content of the array loaded, we should be using the
	value_ind approach.

	However, for cases where we do have the array contents loaded, and we
	do know the bounds of the array, I think we should be using
	value_subscripted_rvalue, which is what we use for non C like
	languages.

	One problem I did run into, exposed by gdb.base/charset.exp, was that
	value_subscripted_rvalue stripped typedefs from the element type of
	the array, which means the value returned will not have the same type
	as an element of the array, but would be the raw, non-typedefed,
	type.  In charset.exp we got back an 'int' instead of a
	'wchar_t' (which is a typedef of 'int'), and this impacts how we print
	the value.  Removing typedefs from the resulting value just seems
	wrong, so I got rid of that, and I don't see any test regressions.

	With this change in place, my original Python script is now doing no
	additional memory accesses, and its performance increases about 10x!

	gdb: make post_startup_inferior a virtual method on inf_ptrace_target
	While working on a later patch that required me to understand how GDB
	starts up inferiors, I was confused by the
	target_ops::post_startup_inferior method.

	The post_startup_inferior target function is only called from
	inf_ptrace_target::create_inferior.

	Part of the target class hierarchy looks like this:

	  inf_child_target
	     |
	     '-- inf_ptrace_target
	            |
	            |-- linux_nat_target
	            |
	            |-- fbsd_nat_target
	            |
	            |-- nbsd_nat_target
	            |
	            |-- obsd_nat_target
	            |
	            '-- rs6000_nat_target

	Every sub-class of inf_ptrace_target, except rs6000_nat_target,
	implements ::post_startup_inferior.  The rs6000_nat_target picks up
	the implementation of ::post_startup_inferior not from
	inf_ptrace_target, but from inf_child_target.

	No descendent of inf_child_target, outside the inf_ptrace_target
	sub-tree, implements ::post_startup_inferior, which isn't really
	surprising, as they would never see the method called (remember, the
	method is only called from inf_ptrace_target::create_inferior).

	What I find confusing is the role inf_child_target plays in
	implementing, what is really a helper function for just one of its
	descendents.

	In this commit I propose that we formally make ::post_startup_inferior
	a helper function of inf_ptrace_target.  To do this I will remove the
	::post_startup_inferior from the target_ops API, and instead make this
	a protected, pure virtual function on inf_ptrace_target.

	I'll remove the empty implementation of ::post_startup_inferior from
	the inf_child_target class, and add a new empty implementation to the
	rs6000_nat_target class.

	All the other descendents of inf_ptrace_target already provide an
	implementation of this method and so don't need to change beyond
	making the method protected within their class declarations.

	To me, this makes much more sense now.  The helper function, which is
	only called from within the inf_ptrace_target class, is now a part of
	the inf_ptrace_target class.

	The only way in which this change is visible to a user is if the user
	turns on 'set debug target 1'.  With this debug flag on, prior to this
	patch the user would see something like:

	  -> native->post_startup_inferior (...)
	  <- native->post_startup_inferior (2588939)

	After this patch these lines are no longer present, as the
	post_startup_inferior is no longer a top level target method.  For me,
	this is an acceptable change.

	gdb: have mips_nbsd_nat_target inherit from nbsd_nat_target
	While working on another patch I had reason to look at
	mips-netbsd-nat.c, and noticed that the class mips_nbsd_nat_target
	inherits directly from inf_ptrace_target.

	This is a little strange as alpha_bsd_nat_target,
	arm_netbsd_nat_target, hppa_nbsd_nat_target, m68k_bsd_nat_target,
	ppc_nbsd_nat_target, sh_nbsd_nat_target, and vax_bsd_nat_target all
	inherit from nbsd_nat_target.

	  Date:   Thu May 3 00:37:22 2018 +0100

	      Convert struct target_ops to C++

	When the target tree was converted to C++, all of the above classes
	inherited from inf_ptrace_target except for hppa_nbsd_nat_target,
	which was the only class that originally inherited from
	nbsd_nat_target.

	Later on all the remaining targets (except mips) were converted to
	inherit from nbsd_nat_target, these are the commits:

	and unfortunately, none of the commits has any real detail that might
	explain why mips was missed out, the only extra context I could find
	was this message:

	  https://sourceware.org/pipermail/gdb-patches/2020-March/166853.html

	Which says that "proper" OS support is going to be added to
	nbsd_nat_target, hence the need to inherit from that class.

	My guess is that leaving mips_nbsd_nat_target unchanged was an
	oversight, so, in this commit, I propose changing mips_nbsd_nat_target
	to inherit from nbsd_nat_target just like all the other nbsd targets.

	My motivation for this patch relates to the post_startup_inferior
	target method.  In a future commit I want to change how this method is
	handled.  Currently the mips_nbsd_nat_target will pick up the empty
	implementation of inf_child_target::post_startup_inferior rather than
	the version in netbsd-nat.c.  This feels like a bug to me, as surely,
	enabling of proc events is something that would need to be done for
	all netbsd targets, regardless of architecture.

	In my future patch I have a choice then, either (a) add a new, empty
	implementation of post_startup_inferior to mips_nbsd_nat_target,
	or (b) this commit, have mips_nbsd_nat_target inherit from
	nbsd_nat_target.  Option (b) seems like the right way to go, hence,
	this commit.

	I've done absolutely no testing for this change, not even building it,
	as that would require at least an environment in which I can x-build
	mips-netbsd applications, which I have no idea how to set up.

	gdb: only include mips and riscv targets if building with 64-bit bfd
	While testing another patch I was trying to build different
	configurations of GDB, and, during one test build I ran into a
	problem, I configured with `--enable-targets=all
	--host=i686-w64-mingw32` and saw this error while linking GDB:

	  .../i686-w64-mingw32/bin/ld: mips-tdep.o: in function `mips_gdbarch_init':
	  .../src/gdb/mips-tdep.c:8730: undefined reference to `disassembler_options_mips'
	  .../i686-w64-mingw32/bin/ld: riscv-tdep.o: in function `riscv_gdbarch_init':
	  .../src/gdb/riscv-tdep.c:3851: undefined reference to `disassembler_options_riscv'

	So the `disassembler_options_mips` and `disassembler_options_riscv`
	symbols are missing.

	This turns out to be because mips-dis.c and riscv-dis.c, in which
	these symbols are defined, are in the TARGET64_LIBOPCODES_CFILES list
	in opcodes/Makefile.am, these files are only built when we are
	building with a 64-bit bfd.

	If we look further, into bfd/Makefile.am, we can see that all the
	files matching elf*-riscv.lo are in the BFD64_BACKENDS list, as are
	the elf*-mips.lo files, and (I know because I tried), the two
	disassemblers do, not surprisingly, depend on features supplied from
	libbfd.

	So, though we can build most of GDB just fine for riscv and mips with
	a 32-bit bfd, if I understand correctly, the final GDB
	executable (assuming we could get it to link) would not understand
	these architectures at the bfd level, nor would there be any
	disassembler available.  This sounds like a pretty useless GDB to me.

	So, in this commit, I move the riscv and mips targets into GDB's list
	of targets that require a 64-bit bfd.  After this I can build GDB just
	fine with the configure options given above.

	This was discussed on the mailing list in a couple of threads:

	  https://sourceware.org/pipermail/gdb-patches/2021-December/184365.html
	  https://sourceware.org/pipermail/binutils/2021-November/118498.html

	and it is agreed, that it is unfortunate that the 32-bit riscv and
	32-bit mips targets require a 64-bit bfd.  If in the future this
	situation ever changes then it would be expected that some (or all) of
	this patch would be reverted.  Until then though, this patch allows
	GDB to build when configured with --enable-targets=all, and when using
	a 32-bit libbfd.

	gdb/testsuite: fix default behavior of runto
	The documented behavior of proc runto is to not emit a PASS when
	succeeding to to run to the specified location, but emit a FAIL when
	failing to do so.  I suppose the intent is that it won't pollute the
	results normally passing tests (although I don't see why we would care),
	but make visible any problems.

	However, it seems like the implementation makes it default to never
	print anything.  "no-message" is prependend to "args", so if "message"
	is not passed, we will always take the   path that sets print_fail to 0,
	which will silence any failure.

	This unfortunately means that tests relying on runto_main won't emit a
	FAIL if failing to run to main.  And since commit 4dfef5be6812
	("gdb/testsuite: make runto_main not pass no-message to runto"), tests
	don't emit a FAIL themselves when failing to run to main.  This means
	that tests failing to run to main just fail silently, and that's bad.

	This can be reproduced by hacking gdb.base/template.exp like so:

	    diff --git a/gdb/testsuite/gdb.base/template.c b/gdb/testsuite/gdb.base/template.c
	    index bcf39c377d92..052be5b79d73 100644

	Running the modified gdb.base/template.exp shows that it exits without

	Remove the line that prepends no-message to args, that should make

	This patch will appear to add many failures, but in reality they already
	existed, they were just silenced.

	gdb, gdbserver: detach fork child when detaching from fork parent
	While working with pending fork events, I wondered what would happen if
	the user detached an inferior while a thread of that inferior had a
	pending fork event.  What happens with the fork child, which is
	ptrace-attached by the GDB process (or by GDBserver), but not known to
	the core?  Sure enough, neither the core of GDB or the target detach the
	child process, so GDB (or GDBserver) just stays ptrace-attached to the
	process.  The result is that the fork child process is stuck, while you
	would expect it to be detached and run.

	Make GDBserver detach of fork children it knows about.  That is done in
	the generic handle_detach function.  Since a process_info already exists
	for the child, we can simply call detach_inferior on it.

	GDB-side, make the linux-nat and remote targets detach of fork children
	known because of pending fork events.  These pending fork events can be
	stored in:

	 - thread_info::pending_waitstatus, if the core has consumed the event
	   but then saved it for later (for example, because it got the event
	   while stopping all threads, to present an all-stop stop on top of a
	   non-stop target)
	 - thread_info::pending_follow: if we ran to a "catch fork" and we
	   detach at that moment

	Additionally, pending fork events can be in target-specific fields:

	 - For linux-nat, they can be in lwp_info::status and
	   lwp_info::waitstatus.
	 - For the remote target, they could be stored as pending stop replies,
	   saved in `remote_state::notif_state::pending_event`, if not
	   acknowledged yet, or in `remote_state::stop_reply_queue`, if
	   acknowledged.  I followed the model of remove_new_fork_children for
	   this: call remote_notif_get_pending_events to process /
	   acknowledge any unacknowledged notification, then look through
	   stop_reply_queue.

	Update the gdb.threads/pending-fork-event.exp test (and rename it to
	gdb.threads/pending-fork-event-detach.exp) to try to detach the process
	while it is stopped with a pending fork event.  In order to verify that
	the fork child process is correctly detached and resumes execution
	outside of GDB's control, make that process create a file in the test
	output directory, and make the test wait $timeout seconds for that file
	to appear (it happens instantly if everything goes well).

	This test catches a bug in linux-nat.c, also reported as PR 28512
	("waitstatus.h:300: internal-error: gdb_signal target_waitstatus::sig()
	const: Assertion `m_kind == TARGET_WAITKIND_STOPPED || m_kind ==
	TARGET_WAITKIND_SIGNALLED' failed.).  When detaching a thread with a
	pending event, get_detach_signal unconditionally fetches the signal
	stored in the waitstatus (`tp->pending_waitstatus ().sig ()`).  However,
	that is only valid if the pending event is of type
	TARGET_WAITKIND_STOPPED, and this is now enforced using assertions (iit
	would also be valid for TARGET_WAITKIND_SIGNALLED, but that would mean
	the thread does not exist anymore, so we wouldn't be detaching it).  Add
	a condition in get_detach_signal to access the signal number only if the
	wait status is of kind TARGET_WAITKIND_STOPPED, and use GDB_SIGNAL_0
	instead (since the thread was not stopped with a signal to begin with).

	Add another test, gdb.threads/pending-fork-event-ns.exp, specifically to
	verify that we consider events in pending stop replies in the remote
	target.  This test has many threads constantly forking, and we detach
	from the program while the program is executing.  That gives us some
	chance that we detach while a fork stop reply is stored in the remote
	target.  To verify that we correctly detach all fork children, we ask
	the parent to exit by sending it a SIGUSR1 signal and have it write a
	file to the filesystem before exiting.  Because the parent's main thread
	joins the forking threads, and the forking threads wait for their fork
	children to exit, if some fork child is not detach by GDB, the parent
	will not write the file, and the test will time out.  If I remove the
	new remote_detach_pid calls in remote.c, the test fails eventually if I
	run it in a loop.

	There is a known limitation: we don't remove breakpoints from the
	children before detaching it.  So the children, could hit a trap
	instruction after being detached and crash.  I know this is wrong, and
	it should be fixed, but I would like to handle that later.  The current
	patch doesn't fix everything, but it's a step in the right direction.

	gdb: move clearing of tp->pending_follow to follow_fork_inferior
	A following patch will change targets so that when they detach an
	inferior, they also detach any pending fork children this inferior may
	have.  While doing this, I hit a case where we couldn't differentiate
	two cases, where in one we should detach the fork detach but not in the
	other.

	Suppose we continue past a fork with "follow-fork-mode == child" &&
	"detach-on-fork on".  follow_fork_inferior calls target_detach to detach
	the parent.  In that case the target should not detach the fork
	child, as we'll continue debugging the child.  As of now, the
	tp->pending_follow field of the thread who called fork still contains
	the details about the fork.

	Then, suppose we run to a fork catchpoint and the user types "detach".
	In that case, the target should detach the fork child in addition to the
	parent.  In that case as well, the tp->pending_follow field contains
	the details about the fork.

	To allow targets to differentiate the two cases, clear
	tp->pending_follow a bit earlier, when following a fork.  Targets will
	then see that tp->pending_follow contains TARGET_WAITKIND_SPURIOUS, and
	won't detach the fork child.

	As of this patch, no behavior changes are expected.

	gdb/remote.c: refactor pending fork status functions
	In preparation for a following patch, refactor a few things that I did
	find a bit awkward, and to make them a bit more reusable.

	 - Pass an inferior to kill_new_fork_children instead of a pid.  That
	   allows iterating on only this inferior's threads and avoid further
	   filtering on the thread's pid.
	 - Change thread_pending_fork_status to return a non-nullptr value only
	   if the thread does have a pending fork status.
	 - Remove is_pending_fork_parent_thread, as one can just use
	   thread_pending_fork_status and check for nullptr.
	 - Replace is_pending_fork_parent with is_fork_status, which just
	   returns if the given target_waitkind if a fork or a vfork.  Push
	   filtering on the pid to the callers, when it is necessary.

	gdbserver: hide fork child threads from GDB
	This patch aims at fixing a bug where an inferior is unexpectedly
	created when a fork happens at the same time as another event, and that
	other event is reported to GDB first (and the fork event stays pending
	in GDBserver).  This happens for example when we step a thread and
	another thread forks at the same time.  The bug looks like (if I
	reproduce the included test by hand):

	    (gdb) show detach-on-fork
	    Whether gdb will detach the child of a fork is on.
	    (gdb) show follow-fork-mode
	    Debugger response to a program call of fork or vfork is "parent".

	    [Switching to Thread 965190.965190]
	    Remote 'g' packet reply is too long (expected 560 bytes, got 816 bytes): ... <long series of bytes>

	The sequence of events leading to the problem is:

	 - We are using the all-stop user-visible mode as well as the
	   synchronous / all-stop variant of the remote protocol
	 - We have two threads, thread A that we single-step and thread B that
	   calls fork at the same time
	 - GDBserver's linux_process_target::wait pulls the "single step
	   complete SIGTRAP" and the "fork" events from the kernel.  It
	   arbitrarily choses one event to report, it happens to be the
	   single-step SIGTRAP.  The fork stays pending in the thread_info.
	 - GDBserver send that SIGTRAP as a stop reply to GDB
	 - While in stop_all_threads, GDB calls update_thread_list, which ends
	   up querying the remote thread list using qXfer:threads:read.
	 - In the reply, GDBserver includes the fork child created as a result
	   of thread B's fork.
	 - GDB-side, the remote target sees the new PID, calls
	   remote_notice_new_inferior, which ends up unexpectedly creating a new
	   inferior, and things go downhill from there.

	The problem here is that as long as GDB did not process the fork event,
	it should pretend the fork child does not exist.  Ultimately, this event
	will be reported, we'll go through follow_fork, and that process will be
	detached.

	The remote target (GDB-side), has some code to remove from the reported
	thread list the threads that are the result of forks not processed by
	GDB yet.  But that only works for fork events that have made their way
	to the remote target (GDB-side), but haven't been consumed by the core
	yet, so are still lingering as pending stop replies in the remote target
	(see remove_new_fork_children in remote.c).  But in our case, the fork
	event hasn't made its way to the GDB-side remote target.  We need to
	implement the same kind of logic GDBserver-side: if there exists a
	thread / inferior that is the result of a fork event GDBserver hasn't
	reported yet, it should exclude that thread / inferior from the reported
	thread list.

	This was actually discussed a while ago, but not implemented AFAIK:

	    https://pi.simark.ca/gdb-patches/1ad9f5a8-d00e-9a26-b0c9-3f4066af5142@redhat.com/#t
	    https://sourceware.org/pipermail/gdb-patches/2016-June/133906.html

	Implementation details-wise, the fix for this is all in GDBserver.  The
	Linux layer of GDBserver already tracks unreported fork parent / child
	relationships using the lwp_info::fork_relative, in order to avoid
	wildcard actions resuming fork childs unknown to GDB.  This information
	needs to be made available to the handle_qxfer_threads_worker function,
	so it can filter the reported threads.  Add a new thread_pending_parent
	target function that allows the Linux target to return the parent of an
	eventual fork child.

	Testing-wise, the test replicates pretty-much the sequence of events
	shown above.  The setup of the test makes it such that the main thread
	is about to fork.  We stepi the other thread, so that the step completes
	very quickly, in a single event.  Meanwhile, the main thread is resumed,
	so very likely has time to call fork.  This means that the bug may not
	reproduce every time (if the main thread does not have time to call
	fork), but it will reproduce more often than not.  The test fails
	without the fix applied on the native-gdbserver and
	native-extended-gdbserver boards.

	At some point I suspected that which thread called fork and which thread
	did the step influenced the order in which the events were reported, and
	therefore the reproducibility of the bug.  So I made the test try  both
	combinations: main thread forks while other thread steps, and vice
	versa.  I'm not sure this is still necessary, but I left it there
	anyway.  It doesn't hurt to test a few more combinations.

	gdb/python: Use tp_init instead of tp_new to setup gdb.Value
	The documentation suggests that we implement gdb.Value.__init__,
	however, this is not currently true, we really implement
	gdb.Value.__new__.  This will cause confusion if a user tries to
	sub-class gdb.Value.  They might write:

	  class MyVal (gdb.Value):
	      def __init__ (self, val):
	          gdb.Value.__init__(self, val)

	  obj = MyVal(123)
	  print ("Got: %s" % obj)

	But, when they source this code they'll see:

	  (gdb) source ~/tmp/value-test.py
	  Traceback (most recent call last):
	    File "/home/andrew/tmp/value-test.py", line 7, in <module>
	      obj = MyVal(123)
	    File "/home/andrew/tmp/value-test.py", line 5, in __init__
	      gdb.Value.__init__(self, val)
	  TypeError: object.__init__() takes exactly one argument (the instance to initialize)
	  (gdb)

	The reason for this is that, as we don't implement __init__ for
	gdb.Value, Python ends up calling object.__init__ instead, which
	doesn't expect any arguments.

	The Python docs suggest that the reason why we might take this
	approach is because we want gdb.Value to be immutable:

	   https://docs.python.org/3/c-api/typeobj.html#c.PyTypeObject.tp_new

	But I don't see any reason why we should require gdb.Value to be
	immutable when other types defined in GDB are not.  This current
	immutability can be seen in this code:

	  obj = gdb.Value(1234)
	  print("Got: %s" % obj)
	  obj.__init__ (5678)
	  print("Got: %s" % obj)

	Which currently runs without error, but prints:

	  Got: 1234
	  Got: 1234

	In this commit I propose that we switch to using __init__ to
	initialize gdb.Value objects.

	This does introduce some additional complexity, during the __init__
	call a gdb.Value might already be associated with a gdb value object,
	in which case we need to cleanly break that association before
	installing the new gdb value object.  However, the cost of doing this
	is not great, and the benefit - being able to easily sub-class
	gdb.Value seems worth it.

	After this commit the first example above works without error, while
	the second example now prints:

	  Got: 1234
	  Got: 5678

	In order to make it easier to override the gdb.Value.__init__ method,
	I have tweaked the definition of gdb.Value.__init__.  The second,
	optional argument to __init__ is a gdb.Type, if this argument is not
	present then GDB figures out a suitable type.

	However, if we want to override the __init__ method in a sub-class,
	and still support the default argument, it is easier to write:

	  class MyVal (gdb.Value):
	      def __init__ (self, val, type=None):
	          gdb.Value.__init__(self, val, type)

	Currently, passing None for the Type will result in an error:

	  TypeError: type argument must be a gdb.Type.

	After this commit I now allow the type argument to be None, in which
	case GDB figures out a suitable type just as if the type had not been
	passed at all.

	Unless a user is trying to reinitialize a value, or create sub-classes
	of gdb.Value, there should be no user visible changes after this
	commit.

2021-12-08  Andrew Burgess  <aburgess@redhat.com>

	gdb: use try/catch around a gdb_disassembler::print_insn call
	While investigating some disassembler problems I ran into this case;
	GDB compiled on a 32-bit arm target, with --enable-targets=all.  Then
	in GDB:

	  (gdb) set architecture i386
	  (gdb) disassemble 0x0,+4
	  unknown disassembler error (error = -1)

	This is interesting because it shows a case where the libopcodes
	disassembler is returning -1 without first calling the
	memory_error_func callback.  Indeed, the return from libopcodes
	happens from this code snippet in i386-dis.c in the print_insn
	function:

	  if (address_mode == mode_64bit && sizeof (bfd_vma) < 8)
	    {
	      (*info->fprintf_func) (info->stream,
				     _("64-bit address is disabled"));
	      return -1;
	    }

	Notice how, prior to the return the disassembler tries to print a
	helpful message out, but GDB doesn't print this message.

	The reason this message goes missing is the call stack, it looks like
	this:

	  gdb_pretty_print_disassembler::pretty_print_insn
	    gdb_disassembler::print_insn
	      gdbarch_print_insn
	        ...
	          i386-dis.c:print_insn

	When i386-dis.c:print_insn returns -1 this is handled in
	gdb_disassembler::print_insn, where an exception is thrown.  However,
	the actual printing of the disassembler output is done in
	gdb_pretty_print_disassembler::pretty_print_insn, and is only done if
	an exception is not thrown.

	In this commit I change this.  The pretty_print_insn now uses
	try/catch around the call to gdb_disassembler::print_insn, if we catch
	an error then we first print any pending output in the instruction
	buffer, before rethrowing the exception.  As a result, even if an
	exception is thrown we still print any pending disassembler output to
	the screen; in the above case the helpful message will now be shown.

	Before my patch we might expect to see this output:

	  (gdb) disassemble 0x0,+4
	  Dump of assembler code from 0x0 to 0x4:
	     0x0000000000000000:	unknown disassembler error (error = -1)
	  (gdb)

	But now we see this:

	  (gdb) disassemble 0x0,+4
	  Dump of assembler code from 0x0 to 0x4:
	     0x0000000000000000:	64-bit address is disabled
	  unknown disassembler error (error = -1)

	If the disassembler returns -1 without printing a helpful message then
	we would still expect a change in output, something like:

	  (gdb) disassemble 0x0,+4
	  Dump of assembler code from 0x0 to 0x4:
	     0x0000000000000000:
	  unknown disassembler error (error = -1)

	Which I think is still acceptable, though at this point I think a
	strong case can be made that this is a disassembler bug (not printing
	anything, but still returning -1).

	Notice however, that the error message is always printed on a new line
	now.  This is also true for the memory error case, where before we
	might see this:

	  (gdb) disassemble 0x0,+4
	  Dump of assembler code from 0x0 to 0x4:
	     0x00000000:	Cannot access memory at address 0x0

	We now get this:

	  (gdb) disassemble 0x0,+4
	  Dump of assembler code from 0x0 to 0x4:
	     0x00000000:
	  Cannot access memory at address 0x0

	For me, I'm happy to accept this change, having the error on a line by
	itself, rather than just appended to the end of the previous line,
	seems like an improvement, but I'm aware others might feel
	differently, so I'd appreciate any feedback.

	[gdb/testsuite] Fix options arg handling in compile_jit_elf_main_as_so
	In commit 80ad340c902 ("[gdb/testsuite] use -Ttext-segment for jit-elf tests")
	the following change was made:
	...
	 proc compile_jit_elf_main_as_so {main_solib_srcfile main_solib_binfile options} {
	-    set options [concat $options debug]
	+    global jit_load_address jit_load_increment
	+
	+    set options [list \
	+       additional_flags="-DMAIN=jit_dl_main" \
	+       additional_flags=-DLOAD_ADDRESS=$jit_load_address \
	+       additional_flags=-DLOAD_INCREMENT=$jit_load_increment \
	+       debug]
	...

	Before the change, the options argument was used, but after the change not
	anymore.

	Fix this by reverting back to using "set options [concat $options ...]".

	Fixing this gets us twice the -DMAIN=jit_dl_main bit, once from a caller, and
	once from compile_jit_elf_main_as_so.  Fix this by removing the bit from
	compile_jit_elf_main_as_so, which makes the code similar to compile_jit_main.

	The cause of the diffferent placement is that we have as line number for main

	...
	$ gdb -q -batch outputs/gdb.tui/basic/basic -ex "info line main"
	Line 20 of "tui-layout.c" starts at address 0x4004a7 <main> \

	Line 21 of "tui-layout.c" starts at address 0x4005f4 <main> \
	  and ends at 0x4005f8 <main+4>.
	...

	Fix this by using a new source file main-one-line.c, that implements the
	entire main function on a single line, in order to force the compiler to use
	that line number.

	Also try to do less hard-coding in the test-case.

	[gdb/tdep] Fix inferior plt calls in PIE for i386
	Consider test-case test.c:
	...
	int main (void) {
	  void *p = malloc (10);
	  return 0;
	}
	...

	When compiled to a non-PIE exec:
	...
	$ gcc -m32 test.c
	...
	the call sequence looks like:
	...
	 8048447:       83 ec 0c                sub    $0xc,%esp
	 804844a:       6a 0a                   push   $0xa
	 804844c:       e8 bf fe ff ff          call   8048310 <malloc@plt>
	...
	which calls to:
	...
	08048310 <malloc@plt>:
	 8048310:       ff 25 0c a0 04 08       jmp    *0x804a00c
	 8048316:       68 00 00 00 00          push   $0x0
	 804831b:       e9 e0 ff ff ff          jmp    8048300 <.plt>
	...
	where the first insn at 0x8048310 initially jumps to the following address
	0x8048316, read from the .got.plt @ 0x804a00c:
	...
	 804a000 0c9f0408 00000000 00000000 16830408  ................
	 804a010 26830408                             &...
	...

	Likewise, when compiled as a PIE:
	...
	$ gcc -m32 -fPIE -pie test.c
	...
	we have this call sequence (with %ebx setup to point to the .got.plt):
	...
	0000055d <main>:
	 579:   83 ec 0c                sub    $0xc,%esp
	 57c:   6a 0a                   push   $0xa

	 580:   e8 6b fe ff ff          call   3f0 <malloc@plt>
	...
	which calls to:

	 3fb:   e9 e0 ff ff ff          jmp    3e0 <.plt>
	...
	where the insn at 0x3f0 initially jumps to following address 0x3f6, read from

	...
	 2000 f41e0000 00000000 00000000 f6030000  ................
	 2010 06040000                             ....
	...

	When instead doing an inferior call to malloc (with nosharedlib to force
	malloc to resolve to malloc@plt rather than the functions in ld.so or libc.so)
	with the non-PIE exec, we have the expected:
	...
	$ gdb -q -batch a.out -ex start -ex nosharedlib -ex "p /x (void *)malloc (10)"
	Temporary breakpoint 1 at 0x8048444

	Temporary breakpoint 1, 0x08048444 in main ()
	$1 = 0x804b160
	...

	But with the PIE exec, we run into:
	...
	$ gdb -q -batch a.out -ex start -ex nosharedlib -ex "p /x (void *)malloc (10)"
	Temporary breakpoint 1 at 0x56c

	Temporary breakpoint 1, 0x5655556c in main ()

	Program received signal SIGSEGV, Segmentation fault.
	0x565553f0 in malloc@plt ()
	...

	The segfault happens because:
	- the inferior call mechanism doesn't setup %ebx
	- %ebx instead is 0
	- the jump to "*0xc(%ebx)" reads from memory at 0xc

	Fix this by setting up %ebx properly in i386_thiscall_push_dummy_call.

	[gdb/testsuite] Use precise align in gdb.arch/i386-{avx,sse}.exp
	Test-cases gdb.arch/i386-{avx,sse}.exp use assembly instructions that require
	the memory operands to be aligned to a certain boundary, and the test-cases
	use C11's _Alignas to make that happen.

	The draw-back of using _Alignas is that while it does enforce a minimum
	alignment, the actual alignment may be bigger, which makes the following
	scenario possible:
	- copy say, gdb.arch/i386-avx.c as basis for a new test-case
	- run the test-case and observe a PASS
	- commit the new test-case in the supposition that the test-case is correct
	  and well-tested
	- run later into a failure on a different test setup (which may be a setup
	  where reproduction and investigation is more difficult and time-consuming),
	  and find out that the specified alignment was incorrect and should have been
	  updated to say, 64 bytes.  The initial PASS occurred only because the actual
	  alignment happened to be greater than required.

	The idea of having precise alignment as a means of having more predictable
	execution which allows flushing out bugs earlier, has been filed as PR
	gcc/103095.

	Add a new file lib/precise-aligned-alloc.c with functions
	precise_aligned_alloc and precise_aligned_dup, to support precise alignment.

	Use precise_aligned_dup in aforementioned test-cases to:
	- verify that the specified alignment is indeed sufficient, rather
	  than too little but accidentally over-aligned.
	- prevent the same type of problems in any new test-cases based on these

	Tested on x86_64-linux, with both gcc and clang.

	(gdb) FAIL: gdb.arch/i386-avx.exp: continue to breakpoint: \

	[GOLD] PowerPC64 inline plt sequences
	The fixes gold failures to handle inline PLT sequences properly.
	PowerPC gold was always turning these back into direct calls due to
	gsym->use_plt_offset() returning false.  This is fixed for dynamic
	linking by correcting get_reference_flags, and for static linking by
	overriding use_plt_offset() in relocate().  The rest of the patch
	revolves around needing to create PLT entries for inline PLT calls
	when statically linking (for gcc -mlongcall).  The lplt section
	handled that for local symbols, now it does globals too.

		* powerpc.cc (Target_powerpc::plt_off): Return proper section
		for static link.
		(Target_powerpc::symval_for_branch): Make public.
		(Target_powerpc::make_lplt_section): Add Symbol_table* param.
		Adjust all calls.
		(Target_powerpc::make_local_plt_entry): Likewise.
		(Target_powerpc::make_local_plt_entry): New variant for global syms.
		(Powerpc_relobj::do_relocate_sections): Don't write lplt contents.
		(Output_data_plt_powerpc::do_write): Write lplt contents here.
		(Output_data_plt_powerpc::Output_data_plt_powerpc): Save
		symbol table pointer.  Adjust all uses.
		(Output_data_plt_powerpc::add_entry): Add stash parameter.  Don't
		do dynamic reloc handling when no reloc section.  Save symbol
		for local plt entries.
		(Output_data_plt_powerpc::add_local_entry): Save symbol.
		(Output_data_plt_powerpc::Local_plt_ent): New class.
		(Output_data_plt_powerpc::sym_ents_): New vector.
		(Target_powerpc::Scan::get_reference_flags): Return
		FUNCTION_CALL|RELATIVE_REF for inline plt relocs.
		(Target_powerpc::Scan::global): Make entries in lplt for inline
		plt call relocation symbols.
		(Target_powerpc::Relocate::relocate): Rename has_plt_offset to

	gdbsupport: fix memory leak in create_file_handler when re-using file handler
	ASan made me notice a memory leak, where the memory tied to the file
	handle name string wasn't freed.  When register a file handler with an
	fd that is already registered, we re-use the file_handler object, so we
	ended up creating a new std::string object and overwriting the
	file_handler::name pointer, without free-ing the old std::string.

	Fix this by allocating file_handler with new, deleting it with
	delete, and making file_handler::name not a pointer.

	gdb/testsuite: fix two "maint info line-table"-related tests
	Commit 92228a334ba2 ("gdb: small "maintenance info line-table"
	readability improvements") change the output format of "maint info
	line-table" slightly, adding some empty lines between each
	line-table.  This causes two tests to start failing, update them to
	account for those empty lines.

	gdb: revert one array_view copy change in ada-lang.c
	Commit 4bce7cdaf481 ("gdbsupport: add array_view copy function") caused
	an internal error when running gdb.ada/packed_array_assign.exp:

	I am not sure what's the root cause of this, whether it is a GDB bug
	exposed by using the array_view copy function or not.  Back out the

	gdb: make extract_integer take an array_view
	I think it would make sense for extract_integer, extract_signed_integer
	and extract_unsigned_integer to take an array_view.  This way, when we
	extract an integer, we can validate that we don't overflow the buffer
	passed by the caller (e.g. ask to extract a 4-byte integer but pass a
	2-byte buffer).

	 - Change extract_integer to take an array_view
	 - Add overloads of extract_signed_integer and extract_unsigned_integer
	   that take array_views.  Keep the existing versions so we don't
	   need to change all callers, but make them call the array_view
	   versions.

	This shortens some places like:

	  result = extract_unsigned_integer (value_contents (result_val).data (),
					     TYPE_LENGTH (value_type (result_val)),
					     byte_order);

	into

	  result = extract_unsigned_integer (value_contents (result_val), byte_order);

	value_contents returns an array view that is of length
	`TYPE_LENGTH (value_type (result_val))` already, so the length is
	implicitly communicated through the array view.

	gdbsupport: add array_view copy function
	An assertion was recently added to array_view::operator[] to ensure we
	don't do out of bounds accesses.  However, when the array_view is copied
	to or from using memcpy, it bypasses that safety.

	To address this, add a `copy` free function that copies data from an
	array view to another, ensuring that the destination and source array
	views have the same size.  When copying to or from parts of an
	array_view, we are expected to use gdb::array_view::slice, which does
	its own bounds check.  With all that, any copy operation that goes out
	of bounds should be caught by an assertion at runtime.

	copy is implemented using std::copy and std::copy_backward, which, at
	least on libstdc++, appears to pick memmove when copying trivial data.
	So in the end there shouldn't be much difference vs using a bare memcpy,
	as we do right now.  When copying non-trivial data, std::copy and
	std::copy_backward assigns each element in a loop.

	To properly support overlapping ranges, we must use std::copy or
	std::copy_backward, depending on whether the destination is before the
	source or vice-versa.  std::copy and std::copy_backward don't support
	copying exactly overlapping ranges (where the source range is equal to
	the destination range).  But in this case, no copy is needed anyway, so
	we do nothing.

	The order of parameters of the new copy function is based on std::copy
	and std::copy_backward, where the source comes before the destination.

	Change a few randomly selected spots to use the new function, to show
	how it can be used.

	Add a test for the new function, testing both with arrays of a trivial
	type (int) and of a non-trivial type (foo).  Test non-overlapping
	ranges as well as three kinds of overlapping ranges: source before dest,
	dest before source, and dest == source.

	store_waitstatus is basically a translation function between a status
	integer and an equivalent target_waitstatus object.  It would make sense
	for it to take the integer as a parameter and return the
	target_waitstatus by value.  Do that, and rename to
	host_status_to_waitstatus.  Users can then do:

	  ws = host_status_to_waitstatus (status)

	which does the right thing, given the move constructor of
	target_waitstatus.

	gdb: return *this in target_waitstatus setters
	While playing with some code creating target_waitstatus objects, I was
	mildly annoyed by the fact that we can't just return a new
	target_waitstatus object.  We have to do:

	    target_waitstatus ws;
	    ws.set_exited (123);
	    return ws;

	Make the setters return the "this" object as a reference, such that it's
	possible to do:

	    return target_waitstatus ().set_exited (123);

	I initially thought of adding static creation functions, which you would
	use like:

	    return target_waitstatus::make_exited (123);

	However, making the setters return a reference to the object achieves
	pretty much the same thing, with less new code.

	  commit 288712bbaca36bff6578bc839ebcdc3707662f81

	      gdb/remote: use scoped_restore to control starting_up flag

	introduced a use after free bug.  The scoped restore added in the
	above commit resets a flag within a remote_target's remote_state
	object.

	However, in some situations, the remote_target can be unpushed before
	the error is thrown.  If the only reference to the target is the one
	in the target stack, then unpushing the target will cause the
	remote_target to be deleted, which, in turn, will delete the
	remote_state object.  The scoped restore will then try to reset the
	flag within a deleted object.

	This problem was caught in the gdb.server/server-connect.exp test,
	which, when run with the address sanitizer enabled, highlights the
	write after free bug described above.

	This commit resolves this issue by adding a new class specifically for
	the purpose of managing the starting_up flag.  As well as setting, and
	then clearing the starting_up flag, this new class increments, and
	then decrements the reference count on the remote_target object.  This
	prevents the remote_target from being deleted until after the flag has
	been reset.

	The gdb.server/server-connect.exp now runs cleanly with the address
	sanitizer enabled.

	libctf: workaround automake bug with conditional info pages
	It looks like automake makes assumptions about its ability to build info
	pages based on the GNU standard behavior of shipping info pages with the
	distributions.  So even though the info pages were conditionalized, and
	automake disabled some of the targets, it was still creeping in by way
	of unconditional INFO_DEPS settings.

	We can workaround this by adding a stub target for the info page when
	building info pages are disabled.  This tricks automake into disabling
	its own extended generation target.  I'll follow up with the automake
	folks to see what they think.

	[gdb/tdep] Fix avx512 -m32 support in gdbserver
	PR27257 reports a problem that can be reproduced as follows:
	- use x86_64 machine with avx512 support
	- compile a hello world with -m32 to a.out
	- start a gdbserver session with a.out
	- use gdb to connect to the gdbserver session

	This makes us run into:
	...
	Listening on port 2346
	Remote debugging from host ::1, port 34940
	src/gdbserver/regcache.cc:257: \
	  A problem internal to GDBserver has been detected.
	Unknown register zmm16h requested
	...

	The problem is that i387_xsave_to_cache in gdbserver/i387-fp.cc can't find a
	register zmm16h in the register cache.

	To understand how this happens, first some background.

	SSE has 16 128-bit wide xmm registers.

	AVX extends the SSE registers set as follows:
	- it extends the 16 existing 128-bit wide xmm registers to 256-bit wide ymm
	  registers.

	AVX512 extends the AVX register set as follows:
	- it extends the 16 existing 256-bit wide ymm registers to 512-bit wide zmm
	  registers.
	- it adds 16 additional 512-bit wide zmm registers (with corresponding ymm and
	  xmm subregisters added as well)

	However, in 32-bit mode, there are only 8 xmm/ymm/zmm registers.

	The problem we're running into is that gdbserver/i387-fp.cc uses these
	constants to describe the size of the register file:
	...
	static const int num_avx512_zmmh_low_registers = 16;
	static const int num_avx512_zmmh_high_registers = 16;
	static const int num_avx512_ymmh_registers = 16;
	static const int num_avx512_xmm_registers = 16;
	...
	which are all incorrect for the 32-bit case.

	Fix this by replacing the constants with variables that have the appropriate
	values in 64-bit and 32-bit mode.

	Tested on x86_64-linux with native and unix/-m32.

	Commit ab557072b8ec ("gdb: use actual DWARF version in compunit's
	debugformat field") changes the debug format string in "info source" to
	show the actual DWARF version, rather than always show "DWARF 2".

	However, it failed to consider that some tests checked for the "DWARF 2"
	string to see if the test program is compiled with DWARF debug
	information.  Since everything is compiled with DWARF 4 or 5 nowadays,
	that changed the behavior of those tests.  Notably, it prevent the
	tests using skip_inline_var_tests to run.

	Grep through the testsuite for "DWARF 2" and change all occurrences I
	could find to use "DWARF [0-9]" instead (that string is passed to TCL's
	string match).

	(PPC64) fix handling of fixed-point values when using "return" command
	In the gdb.ada/fixed_points_function.exp testcase, we have the following
	Ada code...

	   type FP1_Type is delta 0.1 range -1.0 .. +1.0; --  Ordinary
	   function Call_FP1 (F : FP1_Type) return FP1_Type is
	   begin
	      FP1_Arg := F;
	      return FP1_Arg;
	   end Call_FP1;

	... used as follow:

	   F1 : FP1_Type := 1.0;
	   F1 := Call_FP1 (F1);

	The testcase, among other things, verifies that "return" works
	properly as follow:

	    | (gdb) return 1.0
	    | Make pck.call_fp1 return now? (y or n) y
	    | [...]
	    | 9          F1 := Call_FP1 (F1);
	    | (gdb) next
	    | (gdb) print f1
	    | $1 = 0.0625

	The output of the last command shows that we returned the wrong
	value. The value printed gives a clue about the problem, since
	it is 1/16th of the value we expected, where 1/16 is FP1_Type's
	scaling factor.

	The problem, here, comes from the fact that the function
	handling return values for base types (ppc64_sysv_abi_return_value_base)
	writes the return value using unpack_long which, upon seeing that
	the value being unpacked is a fixed point type, applies the scaling
	factor, to get the integer-representation of our fixed-point value
	(similar to what it does with floats, for instance).

	So, the fix consists in teaching ppc64_sysv_abi_return_value_base
	about fixed-point types, and to avoid the unwanted application
	of the scaling factor.

	Note that the "finish" function, on the other hand, does not
	suffer from this issue, simply becaue the value returned by
	the function is read from register without the use of a type,
	thus avoiding an unwanted application of a scaling factor.

	No test added, as this change is already tested by
	gdb.ada/fixed_points_function.exp.

	(RISCV) fix handling of fixed-point type return values
	This commit adds support for TYPE_CODE_FIXED_POINT types for
	"finish" and "return" commands.

	Consider the following Ada code...

	   type FP1_Type is delta 0.1 range -1.0 .. +1.0; --  Ordinary
	   function Call_FP1 (F : FP1_Type) return FP1_Type is
	   begin
	      FP1_Arg := F;
	      return FP1_Arg;
	   end Call_FP1;

	... used as follow:

	   F1 : FP1_Type := 1.0;
	   F1 := Call_FP1 (F1);

	"finish" currently behaves as follow:

	    | (gdb) finish
	    | [...]
	    | Value returned is $1 = 0

	We expect the returned value to be "1".

	Similarly, "return" makes the function return the wrong value:

	    | (gdb) return 1.0
	    | Make pck.call_fp1 return now? (y or n) y
	    | [...]
	    | 9          F1 := Call_FP1 (F1);
	    | (gdb) next
	    | (gdb) print f1
	    | $1 = 0.0625

	(we expect it to print "1" instead).

	This problem comes from the handling of integral return values
	when the return value is actually fixed point type. Our type
	here is actually a range of a fixed point type, but the same
	principles should also apply to pure fixed-point types. For
	the record, here is what the debugging info looks like:

	 <1><238>: Abbrev Number: 2 (DW_TAG_subrange_type)
	    <239>   DW_AT_lower_bound : -16
	    <23a>   DW_AT_upper_bound : 16
	    <23b>   DW_AT_name        : pck__fp1_type
	    <23f>   DW_AT_type        : <0x248>

	 <1><248>: Abbrev Number: 4 (DW_TAG_base_type)
	    <249>   DW_AT_byte_size   : 1
	    <24a>   DW_AT_encoding    : 13      (signed_fixed)
	    <24b>   DW_AT_binary_scale: -4
	    <24c>   DW_AT_name        : pck__Tfp1_typeB
	    <250>   DW_AT_artificial  : 1

	... where the scaling factor is 1/16.

	Looking at the "finish" command, what happens is that riscv_arg_location
	determines that our return value should be returned by parameter using
	an integral convention (via builtin type long). And then,
	riscv_return_value uses a cast to that builtin type long to
	store the value of into a buffer with the right register size.
	This doesn't work in our case, because the underlying value
	returned by the function is unscaled, which means it is 16,
	and thus the cast is like doing:

	   arg_val = (FP1_Type) 16

	... In other words, it is trying to create an FP1_Type enty whose
	value is 16. Applying the scaling factor, that's 256, and because
	the size of FP1_Type is 1 byte, we overflow and thus it ends up
	being zero.

	The same happen with the "return" function, but the other way around.

	The fix consists in handling fixed-point types separately from
	integral types.

2021-12-02  Joel Brobecker  <brobecker@adacore.com>

	(ARM/fixed-point) wrong value shown by "finish" command:
	Consider the following Ada code:

	   type FP1_Type is delta 0.1 range -1.0 .. +1.0; --  Ordinary
	   FP1_Arg : FP1_Type := 0.0;

	   function Call_FP1 (F : FP1_Type) return FP1_Type is
	   begin
	      FP1_Arg := F;
	      return FP1_Arg;
	   end Call_FP1;

	After having stopped inside function Call_FP1 as follow:

	    Breakpoint 1, pck.call_fp1 (f=1) at /[...]/pck.adb:5
	    5             FP1_Arg := F;

	Returning from that function call using "finish" should show
	that the function return "1.0" (the same value as was passed
	as an argument). However, this is not the case:

	    (gdb) finish
	    Run till exit from #0  pck.call_fp1 (f=1)
	    [...]
	    9          F1 := Call_FP1 (F1);
	    Value returned is $1 = 0

	This patch enhances the extraction of the return value to know about
	fixed point types.

2021-12-02  Xavier Roirand  <roirand@adacore.com>

	(Ada/AArch64) fix fixed point argument passing in inferior funcall
	Consider the following code:

	   type FP1_Type is delta 0.1 range -1.0 .. +1.0; --  Ordinary

	   function Call_FP1 (F : FP1_Type) return FP1_Type is
	   begin
	      return F;
	   end Call_FP1;

	When the default in GCC is to generate proper DWARF info for fixed point
	types, then in gdb, printing the result of a call to call_fp1 with a
	decimal parameter leads to:

	  (gdb) p call_fp1(0.5)
	  $1 = 0

	The displayed value is wrong, and we actually expected:

	  (gdb) p call_fp1(0.5)
	  $1 = 0.5

	What happened is that our fixed point type parameter got promoted to a
	32bit integer because we detected that the length of that object was less
	than 4 bytes. The compiler does not perform this promotion and therefore
	GDB should not either.

	This patch fixes the behavior described above.

	Implement 'task apply'
	This adds a 'task apply' command, which is the Ada tasking analogue of
	'thread apply'.  Unlike 'thread apply', it doesn't offer the
	'ascending' flag; but otherwise it's essentially the same.

	Add "task" keyword to the "watch" command
	Breakpoints in gdb can be made specific to an Ada task using the
	"task" qualifier.  This patch applies this same idea to watchpoints.

	aarch64: Add maximum immediate value to aarch64_sys_reg
	The immediate form of MSR has a 4-bit immediate field (in CRm).
	However, many forms of MSR require a smaller immediate.  These cases
	are identified by value in operand_general_constraint_met_p,
	but they're now the common case rather than the exception.

	This patch therefore adds the maximum value to the sys_reg
	description and gets the range from there.  It also enforces
	the minimum of 0, which avoids a situation in which:

	  msr dit, #2

	would give the expected:

	  Error: immediate value out of range 0 to 1

	whereas:

	  msr dit, #-1

	would give:

	  Error: immediate value out of range 0 to 15

	(from the later UIMM4 checking).

	Also:

	- we were reporting the first error above against the wrong operand
	- TCO takes a single-bit immediate, but we previously allowed
	  all 16 values.

	gdb, include: replace pragmas with DIAGNOSTIC macros, fix build with g++ 4.8
	When introducing this code, I forgot that we had some macros for this.
	Replace some "manual" pragma diagnostic with some DIAGNOSTIC_* macros,
	provided by include/diagnostics.h.

	In diagnostics.h:

	 - Add DIAGNOSTIC_ERROR, to enable a diagnostic at error level.
	 - Add DIAGNOSTIC_ERROR_SWITCH, to enable -Wswitch at error level, for
	   both gcc and clang.

	Additionally, using DIAGNOSTIC_PUSH, DIAGNOSTIC_ERROR_SWITCH and
	DIAGNOSTIC_POP seems to misbehave with g++ 4.8, where we see these
	errors:

	      CXX    ada-tasks.o
	    /home/smarchi/src/binutils-gdb/gdb/ada-tasks.c: In function void read_known_tasks():
	    /home/smarchi/src/binutils-gdb/gdb/ada-tasks.c:998:10: error: enumeration value ADA_TASKS_UNKNOWN not handled in switch [-Werror=switch]
	       switch (data->known_tasks_kind)
	              ^

	Because of the POP, the diagnostic should go back to being disabled,
	since it was disabled in the beginning, but that's not what we see
	here.  Versions of GCC >= 5 compile correctly.

	Work around this by making DIAGNOSTIC_ERROR_SWITCH a no-op for GCC < 5.

	Note that this code (already as it exists in master today) enables
	-Wswitch at the error level even if --disable-werror is passed.  It
	shouldn't be a problem, as it's not like a new enumerator will appear
	out of nowhere and cause a build error if building with future
	compilers.  Still, for correctness, we would ideally want to ask the
	compiler to enable -Wswitch at its default level (as if the user had
	passed -Wswitch on the command-line).  There doesn't seem to be a way to
	do this.

	gdb: use actual DWARF version in compunit's debugformat field
	The "info source" command, with a DWARF-compile program, always show
	that the debug info is "DWARF 2":

	    (gdb) info source
	    Current source file is test.c
	    Compilation directory is /home/smarchi/build/binutils-gdb/gdb
	    Located in /home/smarchi/build/binutils-gdb/gdb/test.c
	    Contains 2 lines.
	    Source language is c.
	    Producer is GNU C17 9.3.0 -mtune=generic -march=x86-64 -g3 -gdwarf-5 -O0 -fasynchronous-unwind-tables -fstack-protector-strong -fstack-clash-protection -fcf-protection.
	    Compiled with DWARF 2 debugging format.
	    Includes preprocessor macro info.

	Change it to display the actual DWARF version:

	    (gdb) info source
	    Current source file is test.c
	    Compilation directory is /home/smarchi/build/binutils-gdb/gdb
	    Located in /home/smarchi/build/binutils-gdb/gdb/test.c

	    Compiled with DWARF 5 debugging format.
	    Includes preprocessor macro info.

	The comp_unit_head::version field is guaranteed to be between 2 and 5,
	thanks to the check in read_comp_unit_head.  So we can still use static
	strings to pass to record_debugformat, and keep it efficient.

	gdb/remote: use scoped_restore to control starting_up flag
	This commit makes use of a scoped_restore object to control the
	remote_state::starting_up flag within the remote_target::start_remote
	method.

	Ideally I would have liked to create the scoped_restore inside
	start_remote and just leave the restore in place until the end of the
	scope, however, I'm worried that doing this would change the behaviour
	of GDB.  Specifically, in start_remote, the following code is executed
	once the starting_up flag has been restored to its previous value:

	  if (breakpoints_should_be_inserted_now ())
	    insert_breakpoints ();

	I think (but am not 100% sure) that calling install_breakpoints could
	end up back inside remote_target::can_download_tracepoint, which does
	check the value of remote_state::starting_up.  And so, I'm concerned
	that leaving the scoped_restore in place until the end of start_remote
	will cause a possible change in behaviour.

	To avoid this, and to leave things as close to the current behaviour
	as possible, I've split remote_target::start_remote into two, there's
	the main function body which moves into remote_target::start_remote_1,
	this function uses the scoped_restore to change the ::starting_up
	flag, then there's the old remote_target::start_remote, which now just
	calls ::start_remote_1, and then does the insert_breakpoints call.

	There should be no user visible changes after this commit, unless
	there's a situation where the ::starting_up flag could previously have
	been left set, if this was the case, then this situation should no
	longer be possible.

	aarch64: Check for register aliases before mnemonics
	Previously we would not accept:

		A .req B

	if A happened to be the name of an instruction.  Adding new
	instructions could therefore invalidate existing register aliases.

	I noticed this with a test that used "zero" as a register alias
	for "xzr", where "zero" is now also the name of an SME instruction.
	I don't have any evidence that "real" code is doing this, but it
	seems at least plausible.

	This patch switches things so that we check for register aliases
	first.  It might slow down parsing slightly, but the difference
	is unlikely to be noticeable.

	Things like:

		b	.req + 0

	still work, since create_register_alias checks for " .req ",
	and with the input scrubber, we'll only keep whitespace after
	.req if it's followed by another name.  If there's some valid
	expression that I haven't thought about that is scrubbed to
	" .req ", users could avoid the ambiguity by wrapping .req
	in parentheses.

	The new test for invalid aliases already passed.  I just wanted
	something to exercise the !dot condition.

	I can't find a way of exercising the (existing) p == base condition,
	but I'm not brave enough to say that it can never happen.  If it does
	happen, get_mnemonic_name would return an empty string.

	gdb/python: don't use the 'p' format for parsing args
	When running the gdb.python/py-arch.exp tests on a GDB built
	against Python 2 I ran into some errors.  The problem is that this
	test script exercises the gdb.Architecture.integer_type method, and
	this method uses 'p' as an argument format specifier in a call to
	gdb_PyArg_ParseTupleAndKeywords.

	Unfortunately this specified was only added in Python 3.3, so will
	cause an error for earlier versions of Python.

	This commit switches to use the 'O' specifier to collect a PyObject,
	and then uses PyObject_IsTrue to convert the object to a boolean.

	An earlier version of this patch incorrectly switched from using 'p'
	to use 'i', however, it was pointed out during review that this would
	cause some changes in behaviour, for example both of these will work
	with 'p', but not with 'i':

	  gdb.selected_inferior().architecture().integer_type(32, None)
	  gdb.selected_inferior().architecture().integer_type(32, "foo")

	The new approach of using 'O' works fine with these cases.  I've added
	some new tests to cover both of the above.

	There should be no user visible changes after this commit.

	gdb: fix disassembler regressions for 32-bit arm
	After this commit:

	  commit 76b43c9b5c2b275cbf4f927bfc25984410cb5dd5
	  Date:   Tue Oct 5 15:10:12 2021 +0100

	      gdb: improve error reporting from the disassembler

	We started seeing FAILs in the gdb.base/all-architectures*.exp tests,
	when running on a 32-bit ARM target, though I suspect running on any
	target that compiles such that bfd_vma is 32-bits would also trigger
	the failures.

	The problem is that the test is expected GDB's disassembler to print
	an error like this:

	  Cannot access memory at address 0x0

	However, after the above commit we see an error like:

	  unknown disassembler error (error = -1)

	The reason for this is this code in opcodes/i386-dis.c (in the
	print_insn function):

	  if (address_mode == mode_64bit && sizeof (bfd_vma) < 8)
	    {
	      (*info->fprintf_func) (info->stream,
	                             _("64-bit address is disabled"));
	      return -1;
	    }

	This code effectively disallows us from ever disassembling 64-bit x86
	code if we compiled GDB with a 32-bit bfd_vma.  Notice we return
	-1 (indicating a failure to disassemble), but never call the
	memory_error_func callback.

	Prior to the above commit GDB, when it received the -1 return value
	would assume that a memory error had occurred and just print whatever
	value happened to be in the memory error address variable, the default
	value of 0 just happened to be fine because the test had asked GDB to
	do this 'disassemble 0x0,+4'.

	If we instead change the test to do 'disassemble 0x100,+4' then GDB
	would (previously) have still reported:

	  Cannot access memory at address 0x0

	which makes far less sense.

	In this commit I propose to fix this issue by changing the test to
	accept either the "Cannot access memory ..." string, or the newer
	"unknown disassembler error ..." string.  With this change done the
	test now passes.

	However, there is one weakness with this strategy; if GDB broke such
	that we _always_ reported "unknown disassembler error ..." we would
	never notice.  This clearly would be bad.  To avoid this issue I have
	adjusted the all-architectures*.exp tests so that, when we disassemble
	for the default architecture (the one selected by "auto") we _only_
	expect to get the "Cannot access memory ..." error string.

	[ Note: In an ideal world we should be able to disassemble any
	  architecture at all times.  There's no reason why the 64-bit x86
	  disassembler requires a 64-bit bfd_vma, other than the code happens
	  to be written that way.  We could rewrite the disassemble to not
	  have this requirement, but, I don't plan to do that any time soon. ]

	Further, I have changed the all-architectures*.exp test so that we now
	disassemble at address 0x100, this should avoid us being able to pass
	by printing a default address of 0x0.  I did originally change the
	address we disassembled at to 0x4, however, some architectures,
	e.g. ia64, have a default instruction alignment that is greater than
	4, so would still round down to 0x0.  I could have just picked 0x8 as
	an address, but I figured that 0x100 was likely to satisfy most
	architectures alignment requirements.

	gdb/python: add gdb.RemoteTargetConnection.send_packet
	This commits adds a new sub-class of gdb.TargetConnection,
	gdb.RemoteTargetConnection.  This sub-class is created for all
	'remote' and 'extended-remote' targets.

	This new sub-class has one additional method over its base class,
	'send_packet'.  This new method is equivalent to the 'maint
	packet' CLI command, it allows a custom packet to be sent to a remote
	target.

	The outgoing packet can either be a bytes object, or a Unicode string,
	so long as the Unicode string contains only ASCII characters.

	The result of calling RemoteTargetConnection.send_packet is a bytes
	object containing the reply that came from the remote.

2021-11-30  Andrew Burgess  <aburgess@redhat.com>

	gdb: make packet_command function available outside remote.c
	In a later commit I will add a Python API to access the 'maint packet'
	functionality, that is, sending a user specified packet to the target.

	To make implementing this easier, this commit refactors how this
	command is currently implemented so that the packet_command function
	is now global.

	The new global send_remote_packet function takes an object that is an
	implementation of an abstract interface.  Two functions within this
	interface are then called, one just before a packet is sent to the
	remote target, and one when the reply has been received from the
	remote target.  Using an interface object in this way allows (1) for
	the error checking to be done before the first callback is made, this
	means we only print out what packet it being sent once we know we are
	going to actually send it, and (2) we don't need to make a copy of the
	reply if all we want to do is print it.

	One user visible changes after this commit are the error
	messages, which I've changed to be less 'maint packet' command
	focused, this will make them (I hope) better for when
	send_remote_packet can be called from Python code.

	So:      "command can only be used with remote target"
	Becomes: "packets can only be sent to a remote target"

	And:     "remote-packet command requires packet text as argument"
	Becomes: "a remote packet must not be empty"

	Additionally, in this commit, I've added support for packet replies
	that contain binary data.  Before this commit, the code that printed
	the reply treated the reply as a C string, it assumed that the string
	only contained printable characters, and had a null character only at
	the end.

	One way to show the problem with this is if we try to read the auxv
	data from a remote target, the auxv data is binary, so, before this
	commit:

	  (gdb) target remote :54321
	  ...
	  (gdb) maint packet qXfer:auxv:read::0,1000
	  sending: "qXfer:auxv:read::0,1000"
	  received: "l!"
	  (gdb)

	And after this commit:

	  (gdb) target remote :54321
	  ...

	gdb/python: introduce gdb.TargetConnection object type
	This commit adds a new object type gdb.TargetConnection.  This new
	type represents a connection within GDB (a connection as displayed by
	'info connections').

	There's three ways to find a gdb.TargetConnection, there's a new
	'gdb.connections()' function, which returns a list of all currently
	active connections.

	Or you can read the new 'connection' property on the gdb.Inferior
	object type, this contains the connection for that inferior (or None
	if the inferior has no connection, for example, it is exited).

	Finally, there's a new gdb.events.connection_removed event registry,
	this emits a new gdb.ConnectionEvent whenever a connection is removed
	from GDB (this can happen when all inferiors using a connection exit,
	though this is not always the case, depending on the connection type).
	The gdb.ConnectionEvent has a 'connection' property, which is the
	gdb.TargetConnection being removed from GDB.

	The gdb.TargetConnection has an 'is_valid()' method.  A connection
	object becomes invalid when the underlying connection is removed from
	GDB (as discussed above, this might be when all inferiors using a
	connection exit, or it might be when the user explicitly replaces a
	connection in GDB by issuing another 'target' command).

	The gdb.TargetConnection has the following read-only properties:

	  'num': The number for this connection,

	  'type': e.g. 'native', 'remote', 'sim', etc

	  'description': The longer description as seen in the 'info
	                 connections' command output.

	  'details': A string or None.  Extra details for the connection, for
	             example, a remote connection's details might be
	             'hostname:port'.

	RISC-V: The vtype immediate with more than the defined 8 bits are preserved.
	According the rvv spec,
	https://github.com/riscv/riscv-v-spec/blob/master/vtype-format.adoc

	The bits of vtype immediate from 8 to (xlen - 1) should be reserved.
	Therefore, we should also dump the vtype immediate as numbers, when
	they are set over 8-bits.  I think this is a bug that we used to support
	vediv extension and use the bit 8 and 9 of vtype, but forgot to update
	the behavior when removing the vediv.

	Consider the testcases,

	vsetvli  a0, a1,  0x700    # the reserved bit 10, 9 and 8 are used.
	vsetvli  a0, a1,  0x400    # the reserved bit 10 is used.
	vsetvli  a0, a1,  0x300    # the reserved bit 9 and 8 are used.
	vsetvli  a0, a1,  0x100    # the reserved bit 8 is used.
	vsetivli a0, 0xb, 0x300    # the reserved bit 9 and 8 are used.
	vsetivli a0, 0xb, 0x100    # the reserved bit 8 is used.

	The original objdump shows the following result,

	0000000000000000 <.text>:
	   0:   7005f557                vsetvli a0,a1,1792
	   4:   4005f557                vsetvli a0,a1,1024
	   8:   3005f557                vsetvli a0,a1,e8,m1,tu,mu
	   c:   1005f557                vsetvli a0,a1,e8,m1,tu,mu

	But in fact the correct result should be,

	0000000000000000 <.text>:

	RISC-V: Dump vset[i]vli immediate as numbers once vsew or vlmul is reserved.
	Consider the following case,

	vsetvli  a0, a1,  0x4           # unrecognized vlmul
	vsetvli  a0, a1,  0x20          # unrecognized vsew
	vsetivli a0, 0xb, 0x4           # unrecognized vlmul
	vsetivli a0, 0xb, 0x20          # unrecognized vsew

	For the current dis-assembler, we get the result,

	0000000000000000 <.text>:
	   0:   0045f557                vsetvli a0,a1,e8,(null),tu,mu
	   4:   0205f557                vsetvli a0,a1,e128,m1,tu,mu
	   8:   c045f557                vsetivli        a0,11,e8,(null),tu,mu
	   c:   c205f557                vsetivli        a0,11,e128,m1,tu,mu

	The vsew e128 and vlmul (null) are preserved according to the spec,
	so dump these fields looks wrong.  Consider that we are used to dump
	the unrecognized csr as csr numbers directly, we should also dump
	the whole vset[i]vli immediates as numbers, once the vsew or vlmul
	is reserved.  Therefore, following is what I expected,

	0000000000000000 <.text>:

	Allow DW_ATE_UTF for Rust characters
	The Rust compiler plans to change the encoding of a Rust 'char' type
	to use DW_ATE_UTF.  You can see the discussion here:

	    https://github.com/rust-lang/rust/pull/89887

	However, this fails in gdb.  I looked into this, and it turns out that
	the handling of DW_ATE_UTF is currently fairly specific to C++.  In
	particular, the code here assumes the C++ type names, and it creates
	an integer type.

	This comes from commit 53e710acd ("GDB thinks char16_t and char32_t
	are signed in C++").  The message says:

	    Both places need fixing.  But since I couldn't tell why dwarf2read.c
	    needs to create a new type, I've made it use the per-arch built-in
	    types instead, so that the types are only created once per arch
	    instead of once per objfile.  That seems to work fine.

	... which is fine, but it seems to me that it's also correct to make a
	new character type; and this approach is better because it preserves
	the type name as well.  This does use more memory, but first we
	shouldn't be too concerned about the memory use of types coming from
	debuginfo; and second, if we are, we should implement type interning
	anyway.

	Changing this code to use a character type revealed a couple of
	oddities in the C/C++ handling of TYPE_CODE_CHAR.  This patch fixes
	these as well.

	I filed PR rust/28637 for this issue, so that this patch can be
	backported to the gdb 11 branch.

	[gdb/symtab] Fix segfault in search_one_symtab
	PR28539 describes a segfault in lambda function search_one_symtab due to
	psymbol_functions::expand_symtabs_matching calling expansion_notify with a
	nullptr symtab:
	...
	          struct compunit_symtab *symtab =
	            psymtab_to_symtab (objfile, ps);

	          if (expansion_notify != NULL)
	            if (!expansion_notify (symtab))
	              return false;
	...

	This happens as follows.  The partial symtab ps is a dwarf2_include_psymtab
	for some header file:
	...
	(gdb) p ps.filename
	$5 = 0x64fcf80 "/usr/include/c++/11/bits/stl_construct.h"
	...

	The includer of ps is a shared symtab for a partial unit, with as user:
	...
	(gdb) p ps.includer().user.filename
	$11 = 0x64fc9f0 \
	  "/usr/src/debug/llvm13-13.0.0-1.2.x86_64/tools/clang/lib/AST/Decl.cpp"
	...

	The call to psymtab_to_symtab expands the Decl.cpp symtab (and consequently
	the shared symtab), but returns nullptr because:
	...
	struct dwarf2_include_psymtab : public partial_symtab
	{
	  ...
	  compunit_symtab *get_compunit_symtab (struct objfile *objfile) const override

	...

	Fix this by returning the Decl.cpp symtab instead, which fixes the segfault
	in the PR.

	For now, we don't reformat the files entirely to make it easier to
	review, and in case we need to make adjustments.  Once this feels
	like it's stable, we can flatten the code a bit by removing the if

	For most targets, this doesn't make much of a difference as they only
	have a single .exp.  A few (like cris & frv) have multiple .exp though
	and will see a bit of a speed up.

	The real gain is when testing a multitarget build.  This way we can
	run all the targets in parallel and cut the execution time a bit.
	On my system, it goes from ~155sec to ~100sec.

	We can gain further speedups by splitting up some of the larger .exp

	[gdb/testsuite] Fix FAIL in gdb.base/list-missing-source.exp
	In commit f8080fb7a44 "[gdb/testsuite] Add gdb.base/include-main.exp" a
	file gdb.base/main.c was added, which caused the following regression:
	...
	(gdb) list^M
	<gdb.base/main.c>
	(gdb) FAIL: gdb.base/list-missing-source.exp: list
	...

	The problem is that the test-case does not expect to find a file main.c, but
	now it finds gdb.base/main.c.

	Fix this by using the more specific file name list-missing-source.c.

	Tested on x86_64-linux.

	sim: testsuite: fix bits-gen EXEEXT handling

	sim: testsuite: initial support for OS-specific tests
	We usually test against the newlib/libgloss environment, but for a
	few ports that also support Linux apps, we want to test that logic
	too.  A lot of the C code is written such that it works with either
	newlib/libgloss or glibc/linux toolchains, but we have some tests
	that end up being Linux-specific.  Cris has been using the target
	tuple as a rough proxy for this (where cris*-*-elf is assumed to be
	newlib/libgloss, and everything else is glibc/linux), but that is a
	bit too rough, and it doesn't work in a multitarget build.

	So lets create a few stub files that we can do compile tests with
	to detect the different setups, and then let tests declare which
	one they require (if they require any at all).

	sim: testsuite: rework sim_init usage
	The sim_init function was called by runtest for each test when --tool
	was set to sim.  When we changed to --tool '' to collapse the testsuite
	dir, the init function was no longer called on every test.  However, it
	was still being called explicitly by config/default.exp.  It's not clear
	why that explicit call ever existed since, in the past, it meant it was
	redundant.

	Lets drop the single sim_init call in config/default.exp and move it out
	to all our tests.  This replicates the runtest behavior so we can setup
	variables on a per-test basis which allows us to recollapse the sim_path
	logic back.  We'll also leverage this in the future for toolchain setup.

	Also add a few comments clarifying the overall runtime behavior.

	a big problem currently as we never change --objdir, but in order to
	support parallel test execution, we're going to start setting that
	option, so clean up the code ahead of time.

	We also have to tweak some of the cris tests which were making
	assumptions about the argv[0] value.

	[gdb/testsuite] Add gdb.base/include-main.exp
	The test-case gdb.ada/dgopt.exp uses the -gnatD switch, in combination with
	-gnatG.

	This causes the source file $src/gdb/testsuite/gdb.ada/dgopt/x.adb to be
	expanded into $build/gdb/testsuite/outputs/gdb.ada/dgopt/x.adb.dg, and the
	debug information should refer to the x.adb.dg file.

	That is the case for the .debug_line part:
	...
	The Directory Table is empty.

	 The File Name Table (offset 0x1c):
	  Entry Dir     Time    Size    Name
	  1     0       0       0       x.adb.dg
	...
	but not for the .debug_info part:
	...
	    <11>   DW_AT_name        : $src/gdb/testsuite/gdb.ada/dgopt/x.adb
	    <15>   DW_AT_comp_dir    : $build/gdb/testsuite/outputs/gdb.ada/dgopt
	...

	Filed as PR gcc/103436.

	In C we can generate similar debug information, using a source file that does
	not contain any code, but includes another one that does:
	...
	 $ cat gdb/testsuite/gdb.base/include-main.c
	 #include "main.c"
	...
	such that in the .debug_line part we have:
	...
	 The Directory Table (offset 0x1c):
	  1     /home/vries/gdb_versions/devel/src/gdb/testsuite/gdb.base

	 The File Name Table (offset 0x57):
	  Entry Dir     Time    Size    Name
	  1     1       0       0       main.c

	    <15>   DW_AT_comp_dir    : $build/gdb/testsuite

	In preparation for the next commit, which will add GDB support for

	The implementation provided here is based on this mailing list patch

	  1. The GDB changes have been split into a separate patch, and

	  2. The `riscv_option_args_privspec` variable, which held the valid
	  priv-spec values is now gone, instead we use the `riscv_priv_specs`

	building without Python was broken.  The extension_language_python

	PR gdb/28480: Improve ambiguous member detection
	Basic ambiguity detection assumes that when 2 fields with the same name
	have the same byte offset, it must be an unambiguous request. This is not
	always correct. Consider the following code:

	class empty { };

	class A {
	public:
	  [[no_unique_address]] empty e;
	};

	class B {
	public:
	  int e;
	};

	class C: public A, public B { };

	if we tried to use c.e in code, the compiler would warn of an ambiguity,
	however, since A::e does not demand an unique address, it gets the same
	address (and thus byte offset) of the members, making A::e and B::e have the
	same address. however, "print c.e" would fail to report the ambiguity,
	and would instead print it as an empty class (first path found).

	The new code solves this by checking for other found_fields that have
	different m_struct_path.back() (final class that the member was found
	in), despite having the same byte offset.

	The testcase gdb.cp/ambiguous.exp was also changed to test for this
	behavior.

	coff-go32: consistent 16-byte section alignment
	Section alignment for coff-go32 is inconsistent - The '.text' and
	'.data' sections are 16-byte aligned, but named sections '.text.*' and

	16 bytes, yet '.rodata' and '.rodata.*' are aligned to 4 bytes.  For
	'.bss' all input sections are only aligned to 4 bytes.

	This primarily can cause trouble when using SSE instructions, which
	require their memory operands to be aligned to 16-byte boundaries.

	This patch solves the issue simply by setting the section alignment
	to 16 bytes, for all code and data sections referenced in the default

	In a later commit I plan to add disassembler styling.  In the same way

	While working on another patch I ended up in a situation where I had
	async mode disabled (with 'maint set target-async off'), but the async
	event token got marked anyway.

	In this situation GDB was continually calling into
	remote_target::wait, however, the async token would never become
	unmarked as the unmarking is guarded by target_is_async_p.

	We could just unconditionally unmark the token, but that would feel
	like just ignoring a bug, so, instead, lets assert that if
	!target_is_async_p, then the async token should not be marked.

	This assertion would have caught my earlier mistake.

	gdb: simplify remote_target::is_async_p
	This commit simplifies remote_target::is_async_p by removing the

	In previous commits I have added additional assertions around the
	target_async_permitted flag into target.c, as a result we should now
	be confident that if target_can_async_p returns false, a target will
	never have async mode enabled.  Given this, it should not be necessary
	to check target_async_permitted in remote_target::is_async_p, if this
	flag is false ::is_async_p should return false anyway.  There is an
	assert to this effect in target_is_async_p.

2021-11-25  Andrew Burgess  <aburgess@redhat.com>

	gdb: add asserts in target.c for target_async_permitted
	The target_async_permitted flag allows a user to override whether a
	target can act in async mode or not.  In previous commits I have moved
	the checking of this flag out of the various ::can_async_p methods and
	into the common target.c code.

	In this commit I will add some additional assertions into
	target_is_async_p and target_async.  The rules these assertions are
	checking are:

	  1. A target that returns false for target_can_async_p should never
	  become "async enabled", and so ::is_async_p should always return
	  false.  This is being checked in target_is_async_p.

	  2. GDB should never try to enable async mode for a target that
	  returns false for target_can_async_p, this is checked in
	  target_async.

	There are a few places where we call the ::is_async_p method directly,
	in these cases we will obviously not pass through the assert in
	target_is_async_p, however, there are also plenty of places where we
	do call target_is_async_p so if GDB starts to misbehave we should
	catch it quickly enough.

	changed, which will hopefully catch any direct calls to these methods

	gdb: introduce a new overload of target_can_async_p
	There are a few places where we call the target_ops::can_async_p
	member function directly, instead of using the target_can_async_p
	wrapper.

	In some of these places this is because we need to ask before the
	target has been pushed, and in another location (in target.c) it seems
	unnecessary to go through the wrapper when we are already in target.c
	code.

	However, in the next commit I'd like to hoist some common checks out
	of target specific code into target.c.  To achieve this, in this
	commit, I introduce a new overload of target_can_async_p which takes a
	target_ops pointer, and calls the ::can_async_p method directly.  I
	then make use of the new overload where appropriate.

	gdb: fix help doc for "set index-cache enabled"
	When implementing this command, I put "help doc" as a placeholder for
	the help string, and forgot to update it.  Change it for a real help
	string.

	Revert (part of) "gdb fix for catch-syscall.exp"
	This reverts (par of) commit ab198279120fe7937c0970a8bb881922726678f9.
	This commit changed what the test expects when catching the execve
	syscall based on the behavior seen on a Linux PowerPC machine.  That is,
	we get an "entry" event, but no "return" event.  This is not what we get
	on Linux with other architectures, though, and it seems like a
	PowerPC-specific bug.

	Revert the part of the patch related to this, but not the other hunk.

	gdb: fix crash when reading ECOFF debug information
	In commit:

	  commit 633cf2548bcd3dafe297e21a1dd3574240280d48
	  Date:   Wed May 9 15:42:28 2018 -0600

	      Remove cleanups from mdebugread.c

	the following change was made in the function parse_partial_symbols in
	mdebugread.c:

	  -  fdr_to_pst = XCNEWVEC (struct pst_map, hdr->ifdMax + 1);
	  -  old_chain = make_cleanup (xfree, fdr_to_pst);
	  +  gdb::def_vector<struct pst_map> fdr_to_pst_holder (hdr->ifdMax + 1);
	  +  fdr_to_pst = fdr_to_pst_holder.data ();

	The problem with this change is that XCNEWVEC calls xcalloc, which in
	turn calls calloc, and calloc zero initializes the allocated memory.
	In contrast, the new line gdb::def_vector<struct pst_map> specifically
	does not initialize the underlying memory.

	This is a problem because, later on in this same function, we
	increment the n_globals field within 'struct pst_map' objects stored
	in the vector.  The incrementing is now being done from an
	uninitialized starting point.

	In this commit we switch from using gdb::def_vector to using
	std::vector, this alone should be enough to ensure that the fields are
	initialized to zero.

	However, for extra clarity, I have also added initial values in the
	'struct pst_map' to make it crystal clear how the struct will start
	up.

	This issue was reported on the mailing list here:

	configure.ac: Check for the readline.h explicitly

	AArch64: Add support for AArch64 EFI (efi-*-aarch64).
	This adds support for efi-*-aarch64 by virtue of adding a new PEI target
	pei-aarch64-little.  This is not a full target and only exists to support EFI
	at this time.

	This means that this target does not support relocation processing and is mostly
	a container format.  This format has been added to elf based aarch64 targets
	such that efi images can be made natively on Linux.

	However this target is not valid for use with gas but only with objcopy.

	With these changes the resulting file is recognized as an efi image by
	third party tools:

	gdb: introduce target_waitkind_str, use it in target_waitstatus::to_string
	I would like to print target_waitkind values in debug messages, so I
	think that a target_waitkind-to-string function would be useful.  While
	at it, use it in target_waitstatus::to_string.  This changes the output
	of target_waitstatus::to_string a bit, but I think it is for the better.
	The debug messages will show a string matching exactly the
	target_waitkind enumerator (minus the TARGET_WAITKIND prefix).

	As a convenience, make string_appendf return the same reference to
	string it got as a parameter.  This allows doing this:

	  return string_appendf (str, "foo");

	... keeping the code concise.

	[gdb/symtab] Support .debug_line with DW_FORM_line_strp
	I noticed a new gcc option -gdwarf64 and tried it out (using gcc 11.2.1).

	With a test-case hello.c:
	...
	int
	main (void)
	{
	  printf ("hello\n");
	  return 0;
	}
	...
	compiled like this:
	...
	$ gcc -g -gdwarf64 ~/hello.c
	...
	I ran into:
	...
	$ gdb -q -batch a.out
	DW_FORM_line_strp pointing outside of .debug_line_str section \
	  [in module a.out]
	...

	Debugging gdb revealed that the string offset is:
	...
	(gdb) up
	    objfile=0x182ab70, str_offset=1378684502312,
	    form_name=0xeae9b5 "DW_FORM_line_strp")
	    at src/gdb/dwarf2/section.c:208
	208         error (_("%s pointing outside of %s section [in module %s]"),
	(gdb) p /x str_offset
	$1 = 0x14100000128
	(gdb)
	...
	which is read when parsing a .debug_line entry at 0x1e0.

	Looking with readelf at the 0x1e0 entry, we have:
	...
	 The Directory Table (offset 0x202, lines 2, columns 1):
	  Entry Name
	  0     (indirect line string, offset: 0x128): /data/gdb_versions/devel
	  1     (indirect line string, offset: 0x141): /home/vries
	...
	which in a hexdump looks like:
	...
	  0x00000200 1f022801 00004101 00000201 1f020f02
	...

	What happens is the following:
	- readelf interprets the DW_FORM_line_strp reference to .debug_line_str as
	  a 4 byte value, and sees entries 0x00000128 and 0x00000141.
	- gdb instead interprets it as an 8 byte value, and sees as first entry
	  0x0000014100000128, which is too big so it bails out.

	AFAIU, gdb is wrong.  It assumes DW_FORM_line_strp is 8 bytes on the basis
	that the corresponding CU is 64-bit DWARF.  However, the .debug_line
	contribution has it's own initial_length field, and encodes there that it's
	32-bit DWARF.

	Fix this by using the correct offset size for DW_FORM_line_strp references
	in .debug_line.

	Note: the described test-case does trigger this complaint (both with and
	without this patch):
	...
	$ gdb -q -batch -iex "set complaints 10" a.out
	During symbol reading: intermixed 32-bit and 64-bit DWARF sections
	...

	The reason that the CU has 64-bit dwarf is because -gdwarf64 was passed to
	gcc.  The reason that the .debug_line entry has 32-bit dwarf is because that's
	what gas generates.  Perhaps this is complaint-worthy, but I don't think it
	is wrong.

	Tested on x86_64-linux, using native and target board dwarf64.exp.

	[gdb/testsuite] Support .debug_line v5 in dwarf assembler
	The v5 section version for .debug_line has:
	- two new fields address_size and segment_selector_size
	- a different way to encode the directory and filename tables.

	Add support for this in the dwarf assembler.

	For now, make the v5 directory and filename tables work with the v4 type of
	specification in the test-cases by adding duplicate entries at position 0.

	This will need to be properly fixed with an intrusive fix that changes how
	directory and filename entries are specified in the test-cases, f.i:
	...
	set diridx [include_dir "${srcdir}/${subdir}"]
	set fileidx [file_name "$srcfile" $diridx]
	...

	Tested on x86_64-linux.

	[gdb/testsuite] Speed up MACRO_AT_* calls
	Currently, for each MACRO_AT_range or MACRO_AT_func in dwarf assembly the
	following is done:
	- $srcdir/$subdir/$srcfile is compiled to an executable using
	  flags "debug"
	- a new gdb instance is started
	- the new executable is loaded.

	This is inefficient, because the executable is identical within the same
	Dwarf::assemble call.

	Share the gdb instance in the same Dwarf::assemble invocation, which speeds
	up a make check with RUNTESTFLAGS like this to catch all dwarf assembly
	test-cases:
	...
	rtf=$(echo $(cd src/gdb/testsuite; find gdb.* -type f -name "*.exp" \
	      | xargs grep -l Dwarf::assemble))
	...

	sim: v850: fix cpu_option testsuite handling
	The v850 testsuite code has been testing the $opt variable, but this
	was never actually set anywhere globally or v850-specific.  Instead,
	this was a random variable leaking out of the sh testsuite code.  As
	far as I can tell, it has always been this way.  That means the code
	only ever tested the v850 cpu target (which is the default).

	This failure can be easily seen in practice by running the v850 code
	in isolation and seeing it crash:
	$ runtest v850/allinsns.exp
	...
	Running target unix
	Using /usr/share/dejagnu/baseboards/unix.exp as board description file for target.
	Using /usr/share/dejagnu/config/unix.exp as generic interface file for target.
	Using ../../../sim/testsuite/config/default.exp as tool-and-target-specific interface file.
	WARNING: Assuming target board is the local machine (which is probably wrong).
	You may need to set your DEJAGNU environment variable.
	Running ../../../sim/testsuite/v850/allinsns.exp ...
	ERROR: tcl error sourcing ../../../sim/testsuite/v850/allinsns.exp.
	ERROR: tcl error code TCL LOOKUP VARNAME opt
	ERROR: can't read "opt": no such variable
	    while executing
	"switch -regexp -- $opt {

	Backing up a bit, the reason for this logic in the first place is
	because the common sim testsuite code makes an assumption about the
	assembler options with cpu_option -- the option and its value are
	always separated by an =.  This is not the case with v850.  So tweak
	the core sim logic a bit to support omitting the = so that we can
	switch v850 to the standard all_machs setting and avoid opt entirely.

	    Fix intermittent failures on the H8, particularly H8/SX tests.
	    The upstream GCC tester has  showed spurious execution failures on the
	    H8 target for the H8/SX multilibs. I suspected memory corruption or an
	    uninitialized variable early as the same binary would sometimes work and
	    sometimes it got the wrong result. Worse yet, the point where the test
	    determined it was getting the wrong result would change.

	    Because it only happened on the H8/SX variant I was able to zero in on
	    the "mova" support and the "short form" of those instructions in particular.

	    As the code stands it checks if code->op3.type == 0 to try and identify cases
	    where op3 wasn't filled in and thus we've got the short form of the mova
	    instruction.

	    But for the short-form of those instructions we never set any of the "op3"
	    data structure. We get whatever was lying around -- it's usually zero and
	     thus things usually work, but if the stale data was nonzero, then we'd
	    fail to recognize the instruction as a short-form and fail to set up the
	    various fields appropriately.

	    I initially initialized the op3.type field to zero, but didn't like that
	     because it was inconsistent with how other operands were initialized.
	    Bringing consistency meant using -1 as the initializer value and adjusting
	    the check for short form mova appropriately.

	    I've had this in the upstream GCC tester for perhaps a year at this point
	    and haven't seen any of the intermittent failures again.

	[gdb/build] Check if libsource-highlight is usable
	When building gdb with g++ 4.8.5, I ran into:
	...
	ld: source-cache.o: in function `source_cache::ensure(symtab*)':
	source-cache.c:207: undefined reference to \
	  srchilite::SourceHighlight::SourceHighlight(std::string const&)
	...

	[ I configured gdb without explicit settings related to source-highlight, so
	we're excercising the enable_source_highlight=auto scenario. ]

	The problem is that:
	- the source-highlight library is build with system compiler
	  g++ 7.5.0 which uses the new libstdc++ library abi (see
	  https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html )
	- gdb is build using g++ 4.8.5 which uses the old abi.

	[ There's a compatibility macro _GLIBCXX_USE_CXX11_ABI, but that doesn't work
	for this case.  Instead, it enables the opposite case where the
	source-highlight library is build with g++ 4.8.5 and gdb is build with
	g++ 7.5.0. ]

	Fix this by checking whether the source-highlight library is usable during
	configuration.

	In the enable_source_highlight=auto scenario, this allows the build to skip
	the unusable library and finish successfully.

	In the enable_source_highlight=yes scenario, this allows the build to error
	out earlier.

	RISC-V: Support new .option arch directive.
	https://github.com/riscv/riscv-asm-manual/pull/67

	Format:
	.option arch, +<extension><version>, ...
	.option arch, -<extension>
	.option arch, =<ISA string>

	The new direcitve is used to enable/disable extensions for the specific
	code region.  For example,

	.attribute arch, "rv64ic"   # arch = rv64i2p0_c2p0
	.option push
	.option arch, +d2p0, -c     # arch = rv64i2p0_f2p0_d2p0, f is added implied
	.option arch, =rv32gc       # arch = rv32i2p0_m2p0_a2p0_f2p0_d2p0_c2p0
	.option pop                 # arch = rv64i2p0_c2p0

	Note that,
	1. ".option rvc/norvc" have the same behavior as ".option arch +c/-c".
	2. ".option arch -i" is illegal, since we cannot remove base i extension.
	3. If arch=rv64i2p0, then ".option arch, +i3p0" will update the i's version
	   from 2.0 to 3.0.
	4. If arch=rv64i3p0, then ".option arch, +i" will update the i's version
	   from 2.0 to the default one according to the chosen isa spec.

	For binutils part, we need to support a new direcitve: .variant_cc.
	The function symbol marked by .variant_cc means it need to be resolved
	directly without resolver for dynamic linker.  We also add a new dynamic
	entry, STO_RISCV_VARIANT_CC, to indicate there are symbols with the
	special attribute in the dynamic symbol table of the object.

	I heard that llvm already have supported this in their mainline, so

	dprintf-execution-x-script.exp: Adjust test for native-extended-gdbserver
	Without this commit, doing...

	make check RUNTESTFLAGS="--target_board=native-extended-gdbserver" \
	           TESTS="gdb.base/dprintf-execution-x-script.exp"

	...will show one failure.

	Here's a snippet from gdb.log showing the circumstances - I've trimmed
	the paths for readability:

	builtin_spawn gdb -nw -nx -data-directory data-directory -iex set height 0 -iex set width 0 -iex set auto-connect-native-target off -iex set sysroot -ex set height unlimited -x testsuite/gdb.base/dprintf-execution-x-script.gdb --args testsuite/outputs/gdb.base/dprintf-execution-x-script/dprintf-execution-x-script

	Listening on port 2346
	target extended-remote localhost:2346
	Remote debugging using localhost:2346
	...
	[Tests after this point will pass.]

	Note that the command which spawns gdb prevents the gdb script from
	using the native target via "-iex set auto-connect-native-target off".

	Moreover, the script in question contains a "run" command, so GDB
	doesn't know how to run (since it's prevented from using the native
	target and no alternate "target" command has been issued.  But, once
	GDB finishes starting up, the test will spawn a gdbserver and then
	connect to it.  The other (two) tests after this point both pass.

	I've fixed this by using gdb_test_multiple instead of gdb_test.
	When a "Don't know how to run message" is received, the test is
	unsupported.

	I've also added a comment explaining the reason for needing to check
	for "Don't know how to run" despite bailing out at the top of the test
	via:

	  if ![target_can_use_run_cmd] {
	      return 0
	  }

	gdb: fix ia64-tdep.c build with g++ 4.8
	When building with g++ 4.8, I get:

	      CXX    ia64-tdep.o
	    /home/smarchi/src/binutils-gdb/gdb/ia64-tdep.c:3862:1: error: could not convert '{ia64_allocate_new_rse_frame, ia64_store_argument_in_slot, ia64_set_function_addr}' from '<brace
	-enclosed initializer list>' to 'const ia64_infcall_ops'
	     };
	     ^

	This happens since commit 345bd07cce3 ("gdb: fix gdbarch_tdep ODR
	violation"), which added default values for ia64_infcall_ops fields.  It
	looks like g++ 4.8 doesn't like initializing the ia64_infcall_ops object
	using the brace-enclosed initializer list when the ia64_infcall_ops
	fields are assigned default values.

	Later compilers don't have a problem with that, so I suppose that the
	code is correct, but still, change it to make gcc 4.8 happy.  Don't
	initialize the fields of ia64_infcall_ops directly, instead
	default-initialize ia64_gdbarch_tdep::infcall_ops.

	[gdb/doc] Fix negative repeat count examining memory example
	The documentation for the examining memory command x contains an example:
	...
	You can also specify a negative repeat count to examine memory backward from
	the given address.  For example, 'x/-3uh 0x54320' prints three halfwords (h)
	at 0x54314, 0x54328, and 0x5431c.
	...

	The 0x54328 looks like a typo, which was intended to be 0x54318.

	But the series uses a 4-byte distance, while the halfword size used in the
	command means a 2-byte distance, so the series should be:
	...
	0x5431a, 0x5431c, and 0x5431e.
	...

	Fix this by updating the addresses in the example accordingly.

	Reported here ( https://sourceware.org/pipermail/gdb/2021-November/049784.html

	gdb fix for catch-syscall.exp
	Remove check_continue "execve" from Proc test_catch_syscall_execve.

	The check_continue proceedure checs that the command, execve, starts and
	checks for the return from the command.  The execve command starts a new
	program and thus the return from the command causing the test to fail.

	The call to proc check_continue "execve" is removed and replaced with
	just the call to check_call_to_syscall "execve" to verify the command
	executed.  The next test in proc test_catch_syscall_execve verifies that
	the new program started and hit the break point in main.

	Update the check for the PowerPC architecture.  Power Little Endian systems
	include "le" in the name.  The istarget "power64-*-linux*" check fails to
	match LE sytems.  The expected string is updated to capture both Big Endian
	and Little Endian systems.  Power 10 LE istarget prints as:
	powerpc64le-unknown-linux-gnu.

	This patch fixes three failures and the error:

	    ERROR: can't read "arch1": no such variable

	to the ppc-linux-tdep.c and rs6000-tdep.c files.  Additionally the function
	get_ppc_per_inferior is made external in ppc-tdep.h to make it visible in

	This patch fixes the duplicate tests by adding $name to the

	[gdb/build, s390x] Fix build after gdbarch_tdep changes
	Commit 345bd07cce33 ("gdb: fix gdbarch_tdep ODR violation") changes a
	declaration in s390-tdep.h from

	   struct gdbarch_tdep { ... };

	to

	   struct s390_gdbarch_tdep : gdbarch_tdep { ... };

	and now requires that gdbarch_tdep has been declared before.  Which is
	usually the case, except when compiling s390-linux-nat.c, where
	s390-tdep.h is included before gdbarch.h.  Thus the s390x build errors out
	with the compiler complaining about a missing class name after the colon.

	Fix this in s390-linux-nat.c, by including gdbarch.h before s390-tdep.h.

	sim: testsuite: add support for $pwd replacements
	Extend the common test framework to support $pwd replacements in

	sim: cris: replace @srcdir@ test extension with $srcdir/$subdir
	The common framework supports $srcdir & $subdir replacements already,
	so replace the custom @srcdir@ logic with those.  Since the replace
	happens in slurp_options that cris already uses, we don't have any
	logic to port over there.  We have to duplicate that into the cris
	slurp_rv helper though.

	sim: cris: drop custom "dynamic" test field
	This tag is used to force tests to be built dynamically (i.e. without
	-static linking).  This is because cris-sim.exp in dejagnu turns on
	static linking in ldflags.

	The default configs and runtest flags shouldn't load these boards.
	If these settings are still needed, we should figure out a different
	way of suppressing the stock settings wholesale.  We want these to
	all pass out of the box with little to no configuration so that they
	can run in a multitarget build.

	With dropping "dynamic", it'll be easier to merge the custom cris
	test logic with the common sim test logic.

	gdb: fix length of array view returned by some value_contents functions
	In commit 50888e42dcd3 ("gdb: change functions returning value contents
	to use gdb::array_view"), I believe I made a mistake with the length of
	the array views returned by some functions.  All functions return a view
	of `TYPE_LENGTH (value_type (type))` length.  This is not correct when
	the value's enclosing type is larger than the value's type.  In that
	case, the value's contents buffer is of the size of the enclosing type,
	and the value's actual contents is a slice of that (as returned by
	value_contents).  So, functions value_contents_all_raw,
	value_contents_for_printing and value_contents_for_printing_const are
	not correct.  Since they are meant to return the value's contents buffer
	as a whole, they should have the size of the enclosing type.

	There is nothing that uses the returned array view size at the moment,
	so this didn't cause a problem.  But it became apparent when trying to
	adjust some callers.

	gdbsupport: remove FUNCTION_NAME
	__func__ is standard C++11:

	    https://en.cppreference.com/w/cpp/language/function

	Also, in C++11, __func__ expands to the demangled function name, so the
	mention in the comment above FUNCTION_NAME doesn't apply anymore.
	Finally, in places where FUNCTION_NAME is used, I think it's enough to
	print the function name, no need to print the whole signature.
	Therefore, I propose to just remove FUNCTION_NAME and update users to
	use the standard __func__.

	gdb/gdbsupport: make xstrprintf and xstrvprintf return a unique_ptr
	The motivation is to reduce the number of places where unmanaged
	pointers are returned from allocation type routines.  All of the
	callers are updated.

	gdbsupport: move xfree into its own file
	In the next commit I'd like to reference gdb_unique_ptr within the
	common-utils.h file.  However, this requires that I include
	gdb_unique_ptr.h, which requires that xfree be defined.

	Interestingly, gdb_unique_ptr.h doesn't actually include anything that
	defines xfree, but I was finding that when I added a gdb_unique_ptr.h
	include to common-utils.h I was getting a dependency cycle; before my
	change xfree was defined when gdb_unique_ptr.h was processed, while
	after my change it was not, and this made g++ unhappy.

	To break this cycle, I propose to move xfree into its own header file,
	gdb-xfree.h, which I'll then include into gdb_unique_ptr.h and
	common-utils.cc.

	gdb: throw OPTIMIZED_OUT_ERROR rather than GENERIC_ERROR
	While reviewing this patch:

	  https://sourceware.org/pipermail/gdb-patches/2021-November/183227.html

	I spotted that the patch could be improved if we threw
	OPTIMIZED_OUT_ERROR rather than GENERIC_ERROR in a few places.

	This commit updates error_value_optimized_out and
	require_not_optimized_out to throw OPTIMIZED_OUT_ERROR.

	I ran the testsuite and saw no regressions.  This doesn't really
	surprise me, we don't usually write code like:

	  catch (const gdb_exception_error &ex)
	    {
	      (if ex.error == GENERIC_ERROR)
	        ...
	      else
	        ...
	    }

	There are a three places where we write something like:

	  catch (const gdb_exception_error &ex)
	    {
	      (if ex.error == OPTIMIZED_OUT_ERROR)
	        ...
	    }

	In frame.c:unwind_pc, stack.c:info_frame_command_core, and
	value.c:value_optimized_out, but if we are hitting these cases then
	it's not significantly changing GDB's behaviour.

	gdb: rework "set debuginfod" commands
	As discussed here [1], do some re-work in the "set debuginfod commands".

	First, use "set debuginfod enabled on/off/ask" instead of "set
	debuginfod on/off/ask".  This is more MI-friendly, and it gives an
	output that makes more sense in "info set", for example.

	Then, make the show commands not call "error" when debuginfod support is
	not compiled in.  This makes the commands "show" and "show debuginfod"
	stop early, breaking gdb.base/default.exp:

	    Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/default.exp ...
	    FAIL: gdb.base/default.exp: info set
	    FAIL: gdb.base/default.exp: show

	 - Make the "debuginfod enabled" setting default to "off" when debuginfod
	   support is not compiled in, and "ask" otherwise.
	 - Make the setter of "debuginfod enabled" error out when debuginfod
	   support is not compiled in, so that "debuginfod enabled" will always
	   remain "off" in that case.
	 - Make the setter of "debuginfod verbose" work in any case.  I don't
	   see the harm in letting the user change that setting, since the user will
	   hit an error if they try to enable the use of debuginfod.
	 - I would do the same for the "debuginfod urls" setter, but because
	   this one needs to see the DEBUGINFOD_URLS_ENV_VAR macro, provided by
	   libdebuginfod, I made that one error out as well if debuginfod
	   support is not compiled it (otherwise, I would have left it like
	   "debuginfod verbose".  Alternatively, we could hard-code
	   "DEBUGINFOD_URLS" in the code (in fact, it was prior to this patch,
	   but I think it was an oversight, as other spots use
	   DEBUGINFOD_URLS_ENV_VAR), or use a dummy string to store the setting,
	   but I don't really see the value in that.

	Rename debuginfod_enable to debuginfod_enabled, just so it matches the
	setting name.

	[gdb] Don't use gdb_stdlog for inferior-events
	The test-case gdb.base/foll-vfork.exp contains:
	...
	if [gdb_debug_enabled] {
	    untested "debug is enabled"
	    return 0
	}
	...

	To understand what it does, I disabled this bit and ran with GDB_DEBUG=infrun,
	like so:
	...
	$ cd $build/gdb/testsuite
	$ make check GDB_DEBUG=infrun RUNTESTFLAGS=gdb.base/foll-vfork.exp
	...
	and ran into:
	...
	(gdb) PASS: gdb.base/foll-vfork.exp: exec: \
	  vfork parent follow, through step: set follow-fork parent
	next^M
	33        if (pid == 0) {^M
	(gdb) FAIL: gdb.base/foll-vfork.exp: exec: \
	  vfork parent follow, through step: step
	...

	The problem is that the test-case expects:
	...
	(gdb) PASS: gdb.base/foll-vfork.exp: exec: \
	  vfork parent follow, through step: set follow-fork parent
	next^M
	[Detaching after vfork from child process 28169]^M

	(gdb) PASS: gdb.base/foll-vfork.exp: exec: \
	  vfork parent follow, through step: step
	...
	but the "Detaching" line has been redirected to
	$outputs/gdb.base/foll-vfork/gdb.debug.

	I looked at the documentation of "set logging debugredirect [on|off]":
	...
	  By default, GDB debug output will go to both the terminal and the logfile.
	  Set debugredirect if you want debug output to go only to the log file.
	...
	and my interpretation of it was that "debug output" did not match the
	"messages" description of inferior-events:
	...
	The set print inferior-events command allows you to enable or disable printing
	of messages when GDB notices that new inferiors have started or that inferiors
	have exited or have been detached.
	...

	Fix the discrepancy by not using gdb_stdlog for inferior-events.

	Update the gdb.base/foll-vfork.exp test-case to not require
	gdb_debug_enabled == 0.

	Tested on x86_64-linux.

	Tested test-case gdb.base/foll-vfork.exp with and without GDB_DEBUG=infrun.

	gdb: fix gdbarch_tdep ODR violation
	I would like to be able to use non-trivial types in gdbarch_tdep types.
	This is not possible at the moment (in theory), because of the one
	definition rule.

	To allow it, rename all gdbarch_tdep types to <arch>_gdbarch_tdep, and
	make them inherit from a gdbarch_tdep base class.  The inheritance is
	necessary to be able to pass pointers to all these <arch>_gdbarch_tdep
	objects to gdbarch_alloc, which takes a pointer to gdbarch_tdep.

	These objects are never deleted through a base class pointer, so I
	didn't include a virtual destructor.  In the future, if gdbarch objects
	deletable, I could imagine that the gdbarch_tdep objects could become
	owned by the gdbarch objects, and then it would become useful to have a
	virtual destructor (so that the gdbarch object can delete the owned
	gdbarch_tdep object).  But that's not necessary right now.

	It turns out that RISC-V already has a gdbarch_tdep that is
	non-default-constructible, so that provides a good motivation for this
	change.

	Most changes are fairly straightforward, mostly needing to add some
	casts all over the place.  There is however the xtensa architecture,
	doing its own little weird thing to define its gdbarch_tdep.  I did my
	best to adapt it, but I can't test those changes.

	Deal with full path in .file 0 directive
	Gas uses the directory part, if present, of the .file 0 directive to set
	entry 0 of the directory table in DWARF 5, which represents the "current
	directory".

	Now Gas also uses the file part of the same directive to set entry 0 of the
	file table, which represents the "current compilation file".  But the latter
	need not be located in the former so GCC will use a full path in the file
	part when it is passed a full path:

	gcc -c /full/path/test.c -save-temps

	yields:

	 .file 0 "/current/directory" "/full/path/test.c"

	 The Directory Table (offset 0x22, lines 2, columns 1):

	let's drop it to harmonize the testsuites a little.

	sim: run: add --argv0 option to control argv[0]
	We default argv[0] to the program we run which is a standard *NIX
	convention, but sometimes we want to be able to control the argv[0]
	setting independently (especially for programs that inspect argv[0]
	to change their behavior or output).  Add an option to control it.

	sim: split program path out of argv vector
	We use the program argv to both find the program to run (argv[0]) and
	to hold the arguments to the program.  Most of the time this is fine,
	but if we want to let programs specify argv[0] independently (which is
	possible in standard *NIX programs), this double duty doesn't work.

	So let's split the path to the program to run out into a separate
	field by itself.  This simplifies the various sim_open funcs too.

	By itself, this code is more of a logical cleanup than something that
	is super useful.  But it will open up customization of argv[0] in a
	follow up commit.  Split the changes to make it easier to review.

	sim: bfin: fix mach/xfail usage in tests
	Set the mach to the right value all the time, and update xfail to

	idea of target here doesn't make much sense.

	PowerPC64 @notoc in non-power10 code
	R_PPC64_REL24_P9NOTOC is a variant of R_PPC64_REL24_NOTOC for use on
	@notoc cals from non-power10 code in the rare case that using such a
	construct is useful.  R_PPC64_REL24_P9NOTOC will be emitted by gas
	rather than R_PPC64_REL24_NOTOC when @notoc is used in a branch
	instruction if power10 instructions are not enabled at that point.
	The new relocation tells the linker to not use power10 instructions on
	any stub emitted for that branch, unless overridden by
	--power10-stubs=yes.

	The current linker heuristic of only generating power10 instructions
	for stubs if power10-only relocations are detected, continues to be
	used.

	Fix build with current GCC: EL_EXPLICIT(location) always non-NULL
	Compiling GDB with current GCC (1b4a63593b) runs into this:

	  src/gdb/location.c: In function 'int event_location_empty_p(const event_location*)':
	  src/gdb/location.c:963:38: error: the address of 'event_location::<unnamed union>::explicit_loc' will never be NULL [-Werror=address]

	GCC is right, EL_EXPLICIT is defined as returning the address of an
	union field:

	      /* An explicit location.  */
	      struct explicit_location explicit_loc;
	  #define EL_EXPLICIT(P) (&((P)->u.explicit_loc))

	and thus must always be non-NULL.

	gdb: fix "set scheduler-locking" thread exit hang
	GDB hangs when doing this:

	 - launch inferior with multiple threads
	 - multiple threads hit some breakpoint(s)
	 - one breakpoint hit is presented as a stop, the rest are saved as
	   pending wait statuses
	 - "set scheduler-locking on"
	 - resume the currently selected thread (because of scheduler-locking,
	   it's the only one resumed), let it execute until exit
	 - GDB hangs, not showing the prompt, impossible to interrupt with ^C

	When the resumed thread exits, we expect the target to return a
	TARGET_WAITKIND_NO_RESUMED event, and that's what we see:

	    [infrun] fetch_inferior_event: enter
	      [infrun] scoped_disable_commit_resumed: reason=handling event
	      [infrun] random_pending_event_thread: None found.
	    [Thread 0x7ffff7d9c700 (LWP 309357) exited]
	      [infrun] print_target_wait_results: target_wait (-1.0.0 [process -1], status) =
	      [infrun] print_target_wait_results:   -1.0.0 [process -1],
	      [infrun] print_target_wait_results:   status->kind = no-resumed
	      [infrun] handle_inferior_event: status->kind = no-resumed
	      [infrun] handle_no_resumed: TARGET_WAITKIND_NO_RESUMED (ignoring: found resumed)
	      [infrun] prepare_to_wait: prepare_to_wait
	      [infrun] reset: reason=handling event
	      [infrun] maybe_set_commit_resumed_all_targets: not requesting commit-resumed for target native, no resumed threads
	    [infrun] fetch_inferior_event: exit

	The problem is in handle_no_resumed: we check if some other thread is
	actually resumed, to see if we should ignore that event (see comments in
	that function for more info).  If this condition is true:

	    (thread->executing () || thread->has_pending_waitstatus ())

	... then we ignore the event.  The problem is that there are some non-resumed
	threads with a pending event, which makes us ignore the event.  But these
	threads are not resumed, so we end up waiting while nothing executes, hence
	waiting for ever.

	My first fix was to change the condition to:

	    (thread->executing ()
	     || (thread->resumed () && thread->has_pending_waitstatus ()))

	... but then it occured to me that we could simply check for:

	    (thread->resumed ())

	Since "executing" implies "resumed", checking simply for "resumed"
	covers threads that are resumed and executing, as well as threads that
	are resumed with a pending status, which is what we want.

	RISC-V: Dump objects according to the elf architecture attribute.
	For now we should always generate the elf architecture attribute both for
	elf and linux toolchains, so that we could dump the objects correctly
	according to the generated architecture string.  This patch resolves the
	problem that we probably dump an object with c.nop instructions, but
	in fact the c extension isn't allowed.  Consider the following case,

	nelson@LAPTOP-QFSGI1F2:~/test$ cat temp.s

	The c.nop at address 0x6 is generated for alignment, but since the rvc isn't
	allowed for this object, dump it as a c.nop instruction looks wrong.  After
	applying this patch, I get the following result,

	nelson@LAPTOP-QFSGI1F2:~/test$ ~/binutils-dev/build-elf32-upstream/build-install/bin/riscv32-unknown-elf-objdump -d temp.o

	temp.o:     file format elf32-littleriscv

	   c:   00000013                nop

	For the current objdump, we dump data to .byte/.short/.word/.dword, and
	dump the unknown or unsupported instructions to .2byte/.4byte/.8byte, which
	respectively are 2, 4 and 8 bytes instructions.  Therefore, we shouldn't
	dump the 0x0001 as a c.nop instruction in the above case, we should dump
	it to .2byte 0x1 as a unknown instruction, since the rvc is disabled.

	However, consider that some people may use the new objdump to dump the old
	objects, which don't have any elf attributes.  We usually set the default
	architecture string to rv64g by bfd/elfxx-riscv.c:riscv_set_default_arch.
	But this will cause rvc instructions to be unrecognized.  Therefore, we
	set the default architecture string to rv64gc for disassembler, to keep
	the previous behavior.

	This patch pass the riscv-gnu-toolchain gcc/binutils regressions for
	rv32emc-elf, rv32gc-linux, rv32i-elf, rv64gc-elf and rv64gc-linux
	toolchains.  Also, tested by --enable-targets=all and can build

	been impossible to verify this code actually still works.  Since it
	crashes in ld, and it uses a config option that no other tests uses
	and we want to remove, drop the test to avoid all the trouble.

	sim: io: tweak compiler workaround with error output
	Outputting an extra space broke a cris test.  Change the workaround
	to use %s with an empty string to avoid the compiler warning but not
	output an extra space.

	sim: testsuite: delete unused arm remote host logic
	There's no need to sync testutils.inc with remote hosts.  The one
	we have in the source tree is all we need and only thing we test.
	Delete it to simplify.

	sim: synacor: simplify test generation
	Objcopy was used to create a binary file of just the executable code
	since the environment requires code to based at address 0.  We can
	accomplish the same thing with the -Ttext=0 flag, so switch to that
	to get rid of custom logic.

	Simon pointed out that my recent patches to .debug_loclists caused

	This patch changes this code to unconditionally apply the text offset
	here.  It also changes loclist_describe_location to work more like

	I tested this by running the gdb.dwarf2 tests both with and without

	gdb: adjust x_file fields on COFF readers
	Commit e86fc4a5bc37 ("PR 28447: implement multiple parameters for .file
	on XCOFF") changes the structure associated to the internal
	representation of files in COFF formats.  However, gdb directory update
	has been forgotten, leading to compilation errors of this kind:

	      CXX    coffread.o
	    /home/simark/src/binutils-gdb/gdb/coffread.c: In function 'const char* coff_getfilename(internal_auxent*)':

	[gdb/testsuite] Add gdb.opt/break-on-_exit.exp
	Add a test-case to excercise the problem scenario reported in PR28527 and
	fixed in commit a50bdb99afe "[gdb/tdep, rs6000] Don't skip system call in
	skip_prologue":
	- set a breakpoint on _exit, and
	- verify that it triggers.

	Note that this is not a regression test for that commit.  Since the actual
	code in _exit may vary across os instances, we cannot guarantee that the
	problem will always trigger with this test-case.

	Rather, this test-case is a version of the original test-case
	(gdb.threads/process-dies-while-detaching.exp) that is minimal while still
	reproducing the problem reported in PR28527, in that same setting.

	The benefit of this test-case is that it exercise real-life code and may
	expose similar problems in other settings.  Also, it provides a much easier
	test-case to investigate in case a similar problem occurs.

	Tested on x86_64-linux and ppc64le-linux.

	Test case for Bug 28308
	The purpose of this test is described in the comments in
	dprintf-execution-x-script.exp.

	Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28308

	The name of this new test was based on that of an existing test,
	bp-cmds-execution-x-script.exp.  I started off by copying that test,
	adding to it, and then rewriting almost all of it.  It's different
	enough that I decided that listing the copyright year as 2021
	was sufficient.

2021-11-10  Kevin Buettner  <kevinb@redhat.com>

	Fix PR 28308 - dprintf breakpoints not working when run from script
	This commit fixes Bug 28308, titled "Strange interactions with
	dprintf and break/commands":

	Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28308

	Since creating that bug report, I've found a somewhat simpler way of
	reproducing the problem.  I've encapsulated it into the GDB test case
	which I've created along with this bug fix.  The name of the new test
	is gdb.base/dprintf-execution-x-script.exp, I'll demonstrate the
	problem using this test case, though for brevity, I've placed all
	relevant files in the same directory and have renamed the files to all
	start with 'dp-bug' instead of 'dprintf-execution-x-script'.

	The script file, named dp-bug.gdb, consists of the following commands:

	dprintf increment, "dprintf in increment(), vi=%d\n", vi
	break inc_vi
	commands
	  continue
	end
	run

	Note that the final command in this script is 'run'.  When 'run' is
	instead issued interactively, the  bug does not occur.  So, let's look
	at the interactive case first in order to see the correct/expected
	output:

	$ gdb -q -x dp-bug.gdb dp-bug
	... eliding buggy output which I'll discuss later ...
	(gdb) run
	Starting program: /mesquite2/sourceware-git/f34-master/bld/gdb/tmp/dp-bug
	vi=0
	dprintf in increment(), vi=0

	Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
	26	in dprintf-execution-x-script.c
	vi=1
	dprintf in increment(), vi=1

	Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
	26	in dprintf-execution-x-script.c
	vi=2
	dprintf in increment(), vi=2

	Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
	26	in dprintf-execution-x-script.c
	vi=3
	[Inferior 1 (process 1539210) exited normally]

	In this run, in which 'run' was issued from the gdb prompt (instead
	of at the end of the script), there are three dprintf messages along
	with three 'Breakpoint 2' messages.  This is the correct output.

	Now let's look at the output that I snipped above; this is the output
	when 'run' is issued from the script loaded via GDB's -x switch:

	$ gdb -q -x dp-bug.gdb dp-bug
	Reading symbols from dp-bug...
	Dprintf 1 at 0x40116e: file dprintf-execution-x-script.c, line 38.
	Breakpoint 2 at 0x40113a: file dprintf-execution-x-script.c, line 26.
	vi=0
	dprintf in increment(), vi=0

	Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
	26	dprintf-execution-x-script.c: No such file or directory.
	vi=1

	Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
	26	in dprintf-execution-x-script.c
	vi=2

	Breakpoint 2, inc_vi () at dprintf-execution-x-script.c:26
	26	in dprintf-execution-x-script.c
	vi=3
	[Inferior 1 (process 1539175) exited normally]

	In the output shown above, only the first dprintf message is printed.
	The 2nd and 3rd dprintf messages are missing!  However, all three
	'Breakpoint 2...' messages are still printed.

	Why does this happen?

	bpstat_do_actions_1() in gdb/breakpoint.c contains the following
	comment and code near the start of the function:

	  /* Avoid endless recursion if a `source' command is contained
	     in bs->commands.  */
	  if (executing_breakpoint_commands)
	    return 0;

	  scoped_restore save_executing
	    = make_scoped_restore (&executing_breakpoint_commands, 1);

	Also, as described by this comment prior to the 'async' field
	in 'struct ui' in top.h, the main UI starts off in sync mode
	when processing command line arguments:

	  /* True if the UI is in async mode, false if in sync mode.  If in
	     sync mode, a synchronous execution command (e.g, "next") does not
	     return until the command is finished.  If in async mode, then
	     running a synchronous command returns right after resuming the
	     target.  Waiting for the command's completion is later done on
	     the top event loop.  For the main UI, this starts out disabled,
	     until all the explicit command line arguments (e.g., `gdb -ex
	     "start" -ex "next"') are processed.  */

	This combination of things, the state of the static global
	'executing_breakpoint_commands' plus the state of the async
	field in the main UI causes this behavior.

	This is a backtrace after hitting the dprintf breakpoint for
	the second time when doing 'run' from the script file, i.e.
	non-interactively:

	There are two frames for bpstat_do_actions_1(), one at frame #16 and
	the other at frame #0.  The one at frame #16 is processing the actions
	for Breakpoint 2, which is a 'continue'.  The one at frame #0 is attempting
	to process the dprintf breakpoint action.  However, at this point,
	the value of 'executing_breakpoint_commands' is 1, forcing an early
	return, i.e. prior to executing the command(s) associated with the dprintf
	breakpoint.

	For the sake of comparison, this is what the stack looks like when hitting
	the dprintf breakpoint for the second time when issuing the 'run'

	This relatively short backtrace is due to the current UI's async field
	being set to 1.

	Yet another thing to be aware of regarding this problem is the
	difference in the way that commands associated to dprintf breakpoints
	versus regular breakpoints are handled.  While they both use a command
	list associated with the breakpoint, regular breakpoints will place
	the commands to be run on the bpstat chain constructed in
	bp_stop_status().  These commands are run later on.  For dprintf
	breakpoints, commands are run via the 'after_condition_true' function
	pointer directly from bpstat_stop_status().  (The 'commands' field in
	the bpstat is cleared in dprintf_after_condition_true().  This
	prevents the dprintf commands from being run again later on when other
	commands on the bpstat chain are processed.)

	Another thing that I noticed is that dprintf breakpoints are the only
	type of breakpoint which use 'after_condition_true'.  This suggests
	that one possible way of fixing this problem, that of making dprintf
	breakpoints work more like regular breakpoints, probably won't work.
	(I must admit, however, that my understanding of this code isn't
	complete enough to say why.  I'll trust that whoever implemented it
	had a good reason for doing it this way.)

	The comment referenced earlier regarding 'executing_breakpoint_commands'
	states that the reason for checking this variable is to avoid
	potential endless recursion when a 'source' command appears in
	bs->commands.  We know that a dprintf command is constrained to either
	1) execution of a GDB printf command, 2) an inferior function call of
	a printf-like function, or 3) execution of an agent-printf command.
	Therefore, infinite recursion due to a 'source' command cannot happen
	when executing commands upon hitting a dprintf breakpoint.

	I chose to fix this problem by having dprintf_after_condition_true()
	directly call execute_control_commands().  This means that it no
	longer attempts to go through bpstat_do_actions_1() avoiding the
	infinite recursion check for potential 'source' commands on the
	command chain.  I think it simplifies this code a little bit too, a
	definite bonus.

	Summary:

		* breakpoint.c (dprintf_after_condition_true): Don't call
		bpstat_do_actions_1().  Call execute_control_commands()
		instead.

	Correctly handle DW_LLE_start_end
	When the code to handle DW_LLE_start_end was added (as part of some
	DWARF 5 work), it was written to add the base address.  However, this
	seems incorrect -- the DWARF standard describes this as an address,
	not an offset from the base address.

	This patch changes a couple of spots in dwarf2/loc.c to fix this
	problem.  It then changes decode_debug_loc_addresses to return
	DEBUG_LOC_OFFSET_PAIR instead, which preserves the previous semantics.

	This only showed up on the RISC-V target internally, due to the
	combination of DWARF 5 and a newer version of GCC.  I've updated a
	couple of existing loclists test cases to demonstrate the bug.

	Improve gdb::array_view ctor from contiguous containers
	While reading the interface of gdb::array_view, I realized that the
	constructor that builds an array_view on top of a contiguous container
	(such as std::vector, std::array or even gdb::array_view) can be
	missused.

	Lets consider the following code sample:

		struct Parent
		{
		  Parent (int a): a { a } {}
		  int a;
		};

		std::ostream &operator<< (std::ostream& os, const Parent & p)
		{ os << "Parent {a=" << p.a << "}"; return os; }

		struct Child : public Parent
		{
		  Child (int a, int b): Parent { a }, b { b } {}
		  int b;
		};

		std::ostream &operator<< (std::ostream& os, const Child & p)
		{ os << "Child {a=" << p.a << ", b=" << p.b << "}"; return os; }

		template <typename T>
		void print (const gdb::array_view<const T> &p)
		{
		  std::for_each (p.begin (), p.end (), [](const T &p) { std::cout << p << '\n'; });
		}

	Then with the current interface nothinng prevents this usage of
	array_view to be done:

		const std::array<Child, 3> elts = {
		  Child {1, 2},
		  Child {3, 4},
		  Child {5, 6}
		};
		print_all<Parent> (elts);

	This compiles fine and produces the following output:

		Parent {a=1}
		Parent {a=2}
		Parent {a=3}

	which is obviously wrong.  There is nowhere in memory a Parent-like
	object for which the A member is 2 and this call to print_all<Parent>
	shold not compile at all (calling print_all<Child> is however fine).

	This comes down to the fact that a Child* is convertible into a Parent*,
	and that an array view is constructed to a pointer to the first element
	and a size.  The valid type pointed to that can be used with this
	constructor are restricted using SFINAE, which requires that a
	pointer to a member into the underlying container can be converted into a
	pointer the array_view's data type.

	This patch proposes to change the constraints on the gdb::array_view
	ctor which accepts a container now requires that the (decayed) type of
	the elements in the container match the (decayed) type of the array_view
	being constructed.

	Applying this change required minimum adjustment in GDB codebase, which
	are also included in this patch.

	Tested by rebuilding.

	gdb: tweak scoped_disable_commit_resumed uses when resuming all threads in non-stop
	When doing "continue -a" in non-stop mode, each thread is individually
	resumed while the commit resumed state is enabled.  This forces the
	target to commit each resumption immediately, instead of being able to
	batch things.

	The reason is that there is no scoped_disable_commit_resumed around the
	loop over threads in continue_1, when "non_stop && all_threads" is true.
	Since the proceed function is called once for each thread, the
	scoped_disable_commit_resumed in proceed therefore forces commit-resumed
	between each thread resumption.  Add the necessary
	scoped_disable_commit_resumed in continue_1 to avoid that.

	I looked at the MI side of things, the function exec_continue, and found
	that it was correct.  There is a similar iteration over threads, and
	there is a scoped_disable_commit_resumed at the function scope.  This is
	not wrong, but a bit more than we need.  The branches that just call
	continue_1 do not need it, as continue_1 takes care of disabling commit
	resumed.  So, move the scoped_disable_commit_resumed to the inner scope
	where we iterate on threads and proceed them individually.

	Here's an example debugging a multi-threaded program attached by
	gdbserver (debug output trimmed for brevity):

	    $ ./gdb -nx -q --data-directory=data-directory -ex "set non-stop" -ex "tar rem :1234"
	    (gdb) set debug remote
	    (gdb) set debug infrun
	    (gdb) c -a
	    Continuing.
	    [infrun] proceed: enter
	      [infrun] scoped_disable_commit_resumed: reason=proceeding
	      [remote] Sending packet: $vCont;c:p14388.14388#90

	      [infrun] maybe_call_commit_resumed_all_targets: calling commit_resumed for target remote
	    [infrun] proceed: exit
	    ... and so on for each thread ...

	Notice how we send one vCont;c for each thread.  With the patch applied, we
	send a single vCont;c at the end:

	but code goes beyond that to reach into the fregs that follow.  But
	now that we have anonymous unions, we can reduce the nested names
	and have sregs cover all of these registers.

	Avoid /proc/pid/mem races (PR 28065)
	PR 28065 (gdb.threads/access-mem-running-thread-exit.exp intermittent
	failure) shows that GDB can hit an unexpected scenario -- it can
	happen that the kernel manages to open a /proc/PID/task/LWP/mem file,
	but then reading from the file returns 0/EOF, even though the process
	hasn't exited or execed.

	"0" out of read/write is normally what you get when the address space
	of the process the file was open for is gone, because the process
	execed or exited.  So when GDB gets the 0, it returns memory access
	failure.  In the bad case in question, the process hasn't execed or
	exited, so GDB fails a memory access when the access should have
	worked.

	GDB has code in place to gracefully handle the case of opening the
	/proc/PID/task/LWP/mem just while the LWP is exiting -- most often the
	open fails with EACCES or ENOENT.  When it happens, GDB just tries
	opening the file for a different thread of the process.  The testcase
	is written such that it stresses GDB's logic of closing/reopening the
	/proc/PID/task/LWP/mem file, by constantly spawning short lived
	threads.

	However, there's a window where the kernel manages to find the thread,
	but the thread exits just after and clears its address space pointer.
	In this case, the kernel creates a file successfully, but the file
	ends up with no address space associated, so a subsequent read/write
	returns 0/EOF too, just like if the whole process had execed or
	exited.  This is the case in question that GDB does not handle.

	Oleg Nesterov gave this suggestion as workaround for that race:

	    gdb can open(/proc/pid/mem) and then read (say) /proc/pid/statm.
	    If statm reports something non-zero, then open() was "successfull".

	I think that might work.  However, I didn't try it, because I realized
	we have another nasty race that that wouldn't fix.

	The other race I realized is that because we close/reopen the
	/proc/PID/task/LWP/mem file when GDB switches to a different inferior,
	then it can happen that GDB reopens /proc/PID/task/LWP/mem just after
	a thread execs, and before GDB has seen the corresponding exec event.
	I.e., we can open a /proc/PID/task/LWP/mem file accessing the
	post-exec address space thinking we're accessing the pre-exec address
	space.

	A few months back, Simon, Oleg and I discussed a similar race:

	  [Bug gdb/26754] Race condition when resuming threads and one does an exec
	  https://sourceware.org/bugzilla/show_bug.cgi?id=26754

	The solution back then was to make the kernel fail any ptrace
	operation until the exec event is consumed, with this kernel commit:

	 commit dbb5afad100a828c97e012c6106566d99f041db6
	 Author:     Oleg Nesterov <oleg@redhat.com>
	 AuthorDate: Wed May 12 15:33:08 2021 +0200
	 Commit:     Linus Torvalds <torvalds@linux-foundation.org>
	 CommitDate: Wed May 12 10:45:22 2021 -0700

	     ptrace: make ptrace() fail if the tracee changed its pid unexpectedly

	This however, only applies to ptrace, not to the /proc/pid/mem file
	opening case.  Also, even if it did apply to the file open case, we
	would want to support current kernels until such a fix is more wide
	spread anyhow.

	So all in all, this commit gives up on the idea of only ever keeping
	one /proc/pid/mem file descriptor open.  Instead, make GDB open a
	/proc/pid/mem per inferior, and keep it open until the inferior exits,
	is detached or execs.  Make GDB open the file right after the inferior
	is created or is attached to or forks, at which point we know the
	inferior is stable and stopped and isn't thus going to exec, or have a
	thread exit, and so the file open won't fail (unless the whole process
	is SIGKILLed from outside GDB, at which point it doesn't matter
	whether we open the file).

	This way, we avoid both races described above, at the expense of using
	more file descriptors (one per inferior).

	gdb/testsuite: use gdb_get_line_number
	Replaces a hard coded line number with a use of gdb_get_line_number.

	I suspect that the line number has, over time, come adrift from where
	it was supposed to be stopping.  When the test was first added, line
	770 pointed at the final 'return 0' in function main.  Over time, as
	things have been added, line 770 now points at some random location in
	the middle of main.

	So, I've marked the 'return 0' with a comment, and now the test will
	always stop there.

	I also removed an old comment from 1997 talking about how these tests
	will only pass with the HP compiler, followed by an additional comment
	from 2000 saying that the tests now pass with GCC.

	I get the same results before and after this change.

	gdb: introduce "set index-cache enabled", deprecate "set index-cache on/off"
	The "set index-cache" command is used at the same time as a prefix
	command (prefix for "set index-cache directory", for example), and a
	boolean setting for turning the index-cache on and off.  Even though I
	did introduce that, I now don't think it's a good idea to do something
	non-standard like this.

	First, there's no dedicated CLI command to show whether the index-cache
	is enabled, so it has to be custom output in the "show index-cache
	handler".  Also, it means there's no good way a MI frontend can find out
	if the index-cache is enabled.  "-gdb-show index-cache" doesn't show it
	in the MI output record:

	    (gdb) interpreter-exec mi "-gdb-show index-cache"
	    ~"\n"
	    ~"The index cache is currently disabled.\n"
	    ^done,showlist={option={name="directory",value="/home/simark/.cache/gdb"}}

	Fix this by introducing "set/show index-cache enabled on/off", regular
	boolean setting commands.  Keep commands "set index-cache on" and "set
	index-cache off" as deprecated aliases of "set index-cache enabled",
	with respectively the default arguments "on" and "off".

	Update tests using "set index-cache on/off" to use the new command.
	Update the regexps in gdb.base/maint.exp to figure out whether the
	index-cache is enabled or not.  Update the doc to mention the new
	commands.

	gdb: pass/return setting setter/getter scalar values by value
	The getter and setter in struct setting always receive and return values
	by const reference.  This is not necessary for scalar values (like bool
	and int), but more importantly it makes it a bit annoying to write a
	getter, you have to use a scratch static variable or something similar
	that you can refer to:

	  const bool &
	  my_getter ()
	  {
	    static bool value;
	    value = function_returning_bool ();
	    return value;
	  }

	Change the getter and setter function signatures to receive and return
	value by value instead of by reference, when the underlying data type is
	scalar.  This means that string-based settings will still use
	references, but all others will be by value.  The getter above would
	then be re-written as:

	  bool
	  my_getter ()
	  {
	    return function_returning_bool ();
	  }

	This is useful for a patch later in this series that defines a boolean
	setting with a getter and a setter.

	[AArch64] Make gdbserver register set selection dynamic
	The current register set selection mechanism for AArch64 is static, based
	on a pre-populated array of register sets.

	This means that we might potentially probe register sets that are not
	available. This is OK if the kernel errors out during ptrace, but probing the
	tag_ctl register, for example, does not result in a ptrace error if the kernel
	supports the tagged address ABI but not MTE (PR 28355).

	Making the register set selection dynamic, based on feature checks, solves
	this and simplifies the code a bit. It allows us to list all of the register
	sets only once, and pick and choose based on HWCAP/HWCAP2 or other properties.

	I plan to backport this fix to GDB 11 as well.

	==1909567==ABORTING

	Despite the code called properly operator new[] and operator delete[].
	But GDB's new-op.cc provides its own operator new[] which gets translated into
	malloc() (which gets recogized as operatore new(size_t)) but as it does not
	translate also operators delete[] Address Sanitizer gets confused.

	The question is how many variants of the delete operator need to be provided.
	There could be 14 operators new but there are only 4, GDB uses 3 of them.
	There could be 16 operators delete but there are only 6, GDB uses 2 of them.
	It depends on libraries and compiler which of the operators will get used.
	Currently being used:
	                 U operator new[](unsigned long)
	                 U operator new(unsigned long)
	                 U operator new(unsigned long, std::nothrow_t const&)
	                 U operator delete[](void*)

	asan: dlltool buffer overflow: embedded NUL in string
	yyleng gives the pattern length, xstrdup just copies up to the NUL.
	So it is quite possible writing at an index of yyleng-2 overflows
	the xstrdup allocated string buffer.  xmemdup quite handily avoids
	this problem, even writing the terminating NUL over the trailing
	quote.  Use it in ldlex.l too where we'd already had a report of this

	sim: mloop: mark a few conditionally used funcs as unused
	These are marked inline, so building w/gcc at higher optimization
	levels will automatically discard them.  But building with -O0 will
	trigger unused function warnings, so fix that.

	The common before/after cover functions in the common mloop generator
	are not used by all architecture ports.  Doesn't seem to be a hard
	requirement, so marking them optional (i.e. unused) is fine.

	The cris execute function is conditionally used depending on the
	fast-build mode settings, so mark it unused too.

	That assert would be more obvious if it were reported as
	"addr_ranges <= end_ranges".  Fix that by using the obvious variable
	in the final loop.  Stop the assertion by using a signed comparison:
	It's possible for the rounding up of the arange pointer to exceed the
	end of the block when the block size is fuzzed.

	What happens to cause the failure is that the two branches in

	    -re "\r\nDuring symbol reading: location description stack underflow" {

	    -re "\r\nDuring symbol reading: location description stack overflow" {

	sim: nltvals: localize TARGET_<open> defines
	Code should not be using these directly, instead they should be
	resolving these dynamically via the open_map.  Rework the common
	callback code that was using the defines to use symbolic names
	instead, and localize some of the defines in the ARM code (since
	it's a bit unclear how many different APIs it supports currently),
	then remove the defines out of the header so no new code can rely on
	them.

	Like we just did for pulling out the errno map, pull out the signal
	map into a dedicated common file.  All newlib ports are using the

2021-10-31  Mike Frysinger  <vapier@gentoo.org>

	sim: nltvals: pull target errno out into a dedicated source file
	The current system maintains a list of target errno constants in the
	nltvals.def file, then runs a build-time tool to turn that into a C
	file.  This list of errno values is the same for all arches, so we
	don't need the arch-specific flexibility.  Further, these are only
	for newlib/libgloss environments, which makes it confusing to support
	other userland runtimes (like Linux).  Let's simplify to make this
	easier to understand & build.  We don't namespace the variables yet,
	but sets up the framework for it.

	Create a new target-newlib-errno.c template file.  The template file
	is hand written, but the inline map is still automatically generated.

	This allows us to move it to the common set of objects so it's only
	built once in a multi-target build.

	Now we can remove the output from the gentmap build-time tool since
	it's checked into the tree.

	Then we stop including the errno lists in nltvals.def since nothing
	uses it.

	sim: fix compilation on mingw64 [PR sim/28476]
	...by reordering includes.

	1. sim-utils.c

	sim/mips/sim-main.h defines UserMode, while there is a struct in winnt.h
	which has UserMode as a member. So if sim-main.h is included before winnt.h,
	compilation fails.

	2. ppc

	registers.h defines CR, which is used as a member in winnt.h.

	winsock2.h is included by sys/time.h, so sys/time.h has to be included
	before registers.h.

	Don't include coff/pe.h in coff-x86_64.c
	This (and other) code from coffcode.h is broken for x86_64_coff_vec,
	and has been ever since support was added in 2006 commit 99ad839030c1
	Here, bfd_coff_aoutsz must match coff_swap_aouthdr_out otherwise we
	end up writing garbage.

	      /* Note that peicode.h fills in a PEAOUTHDR, not an AOUTHDR.
		 include/coff/pe.h sets AOUTSZ == sizeof (PEAOUTHDR)).  */
	      char * buff;
	      bfd_size_type amount = bfd_coff_aoutsz (abfd);

	      buff = (char *) bfd_malloc (amount);
	      if (buff == NULL)
		return false;

	      coff_swap_aouthdr_out (abfd, & internal_a, buff);
	      amount = bfd_bwrite (buff, amount, abfd);

	We have removed support for --target=x86_64-coff, likely because it
	never worked properly, but still produce coff-x86_64.o with
	--enable-targets=all.  This means objcopy can recognize x86_64 COFF
	files but will write garbage to the output file, a fact found by
	fuzzers.  I suspect x86_64 COFF is still broken after this fix, and
	mention of coff-x86_64.* should be removed from bfd/Makefile.am.

		* coff-x86_64.c: Don't include coff/pe.h.
		(COFF_WITH_pex64): Don't define here.

2021-10-29  Tom Tromey  <tromey@adacore.com>

	Document resolve_dynamic_type oddity
	Today I re-learned that resolve_dynamic_type can return a type for
	which is_dynamic_type returns true.  This can happen for an array
	whose elements have dynamic type -- the array is reported as dynamic,
	but resolving the elements would be incorrect, because each element
	might have a different type after resolution.

	You can see the special case in resolve_dynamic_array_or_string:

	  if (ary_dim != NULL && ary_dim->code () == TYPE_CODE_ARRAY)
	...
	  else
	...

	I looked into having the TYPE_CODE_ARRAY case in
	is_dynamic_type_internal follow this same logic, but that breaks down
	on the gdb.fortran/dynamic-ptype-whatis.exp test case.  In particular
	this code in fortran_undetermined::evaluate:

	  value *callee = std::get<0> (m_storage)->evaluate (nullptr, exp, noside);
	  if (noside == EVAL_AVOID_SIDE_EFFECTS
	      && is_dynamic_type (value_type (callee)))
	    callee = std::get<0> (m_storage)->evaluate (nullptr, exp, EVAL_NORMAL);

	... relies on is_dynamic_type returning true for such an array.

	I wasn't really sure of the best way to fix this, so in the meantime I
	wrote this patch, which documents the oddity so that I might have a
	chance of remembering this in the future.

	Avoid self-test failures on x86-linux
	The disassembly tests in "maint selftest" will fail on x86-linux.
	This happens because opcodes rejects an attempt to disassemble for an
	arch with a 64-bit address size when bfd_vma is 32-bit.

	This patch avoids this problem by avoiding the test in this case.  I
	chose to do it this way because this seems to be the only situation
	where opcodes checks the size of bfd_vma.

	For v2 of this patch, I've also updated memory_error_test to do the
	same thing.  This is needed due to the "improve error reporting from
	the disassembler" patch.

	gdb: add "maint set/show selftest verbose" commands and use process_options
	I saw the new -verbose switch to "maint selftests" and thought it would
	be nice for it to use the option framework.  For example, that makes
	having completion easy.  It's not that high value, given this is a
	maintenance command, but I had never used the framework myself, so it
	was a good way to practice.

	This patch also adds the "maint set/show selftest verbose" setting.  It
	would be possible to use option framework without adding the setting,
	but using the framework makes adding the option almost trivial, so I
	thought why not.

	[gdb/symtab] Handle DW_AT_string_length with location list
	Consider a fortran routine where a string variable s is modified:
	...
	subroutine f(s)
	  character*(*) s
	  print *, s
	  s(1:3) = 'oof'
	  print *, s
	end subroutine f
	...

	When compiling with optimization level -O1 and printing the type of
	variable s we get:
	...
	$ gdb -q -batch outputs/gdb.opt/fortran-string/fortran-string \
	  -ex "b f" \
	  -ex run \
	  -ex "ptype s"
	Breakpoint 1 at 0x4006f7: file fortran-string.f90, line 21.

	Breakpoint 1, f (s=..., _s=_s@entry=3) at fortran-string.f90:21
	21      subroutine f(s)
	type = character*1
	...
	while with -O0 we have instead:
	...
	type = character (3)
	...

	The problem is that the type of s is:
	...
	 <1><2d6>: Abbrev Number: 21 (DW_TAG_string_type)
	    <2d7>   DW_AT_string_length: 0xbf (location list)

	Fix watchpoints with multiple threads on Windows
	A recent internal change pointed out that watchpoints were not working
	on Windows when the inferior was multi-threaded.  This happened
	because the debug registers were only updated for certain threads --
	in particular, those that were being resumed and that were not marked
	as suspended.  In the case of single-stepping, the need to update the
	debug registers in other threads could also be "forgotten".

	This patch changes windows-nat.c to mark all threads needing a debug
	register update.  This brings the code closer to what gdbserver does
	(though, unfortunately, it still seems more complicated than needed).

	opcodes: Fix RPATH not being set for dynamic libbfd dependency
	If built as a shared library, libopcodes has a load-time dependency on
	libbfd, which is recorded in the dynamic section, however without a
	corresponding RPATH entry for the directory to find libbfd in.  This
	causes loading to fail whenever libbfd is only pulled by libopcodes
	indirectly and libbfd has been installed in a directory that is not in
	the dynamic loader's search path.

	It does not happen with the programs included with binutils or GDB,
	because they all also pull libbfd when using libopcodes, but it can
	happen with external software, e.g.:

	$ gdbserver --help
	gdbserver: error while loading shared libraries: libbfd-[...].so: cannot open shared object file: No such file or directory
	$

	(not our `gdbserver').

	Indirect dynamic dependencies are handled by libtool automatically by
	adding RPATH entries as required, however our setup for libopcodes
	prevents this from happening by linking in libbfd with an explicit file
	reference sneaked through to the linker directly behind libtool's back
	via the `-Wl' linker command-line option rather than via `-l' combined
	with a suitable library search path specified via `-L', as it would be
	usually the case, or just referring to the relevant .la file in a fully
	libtool-enabled configuration such as ours.

	According to an observation in the discussion back in 2007[1][2][3] that
	has led to the current arrangement it is to prevent libtool from picking
	up the wrong version of libbfd.  It does not appear to be needed though,
	not at least with our current libtool incarnation, as directly referring
	`libbfd.la' does exactly what it should, as previously suggested[4], and
	with no link-time reference to the installation directory other than to
	set RPATH.  Uninstalled version of libopcodes has libbfd's build-time
	location prepended to RPATH too, as also expected.

	Use a direct reference to `libbfd.la' then, making the load error quoted
	above go away.  Alternatively `-L' and `-l' could be used to the same
	effect, but it seems an unnecessary complication and just another way to
	circumvent rather than making use of libtool.

	gdb: change functions returning value contents to use gdb::array_view
	The bug fixed by this [1] patch was caused by an out-of-bounds access to
	a value's content.  The code gets the value's content (just a pointer)
	and then indexes it with a non-sensical index.

	This made me think of changing functions that return value contents to
	return array_views instead of a plain pointer.  This has the advantage
	that when GDB is built with _GLIBCXX_DEBUG, accesses to the array_view
	are checked, making bugs more apparent / easier to find.

	This patch changes the return types of these functions, and updates
	callers to call .data() on the result, meaning it's not changing
	anything in practice.  Additional work will be needed (which can be done
	little by little) to make callers propagate the use of array_view and
	reap the benefits.

	libctf, ld: handle nonrepresentable types better
	ctf_type_visit (used, among other things, by the type dumping code) was
	aborting when it saw a nonrepresentable type anywhere: even a single
	structure member with a nonrepresentable type caused an abort with
	ECTF_NONREPRESENTABLE.  This is not useful behaviour, given that the
	abort comes from a type-resolution we are only doing in order to
	determine whether the type is a structure or union.  We know
	nonrepresentable types can't be either, so handle that case and
	pass the nonrepresentable type down.

	(The added test verifies that the dumper now handles this case and
	prints nonrepresentable structure members as it already does
	nonrepresentable top-level types, rather than skipping the whole
	structure -- or, without the previous commit, skipping the whole types
	section.)

	binutils: make objdump/readelf --ctf-parent actually useful
	This option has been present since the very early days of the
	development of libctf as part of binutils, and it shows.  Back in the
	earliest days, I thought we might handle ambiguous types by introducing
	new ELF sections on the fly named things like .ctf.foo.c for ambiguous
	types found only in foo.c, etc.  This turned out to be a terrible idea,
	so we moved to using a CTF archive in the .ctf section which contained
	all the CTF dictionaries -- but the --ctf-parent option in objdump and
	readelf was never adjusted, and lingered as a mechanism to specify CTF
	parent dictionaries in sections other than .ctf, even though the linker
	has no way to produce parent dictionaries in different sections from
	their children, libctf's ctf_open can't handle such split-up
	parent/child dicts, and they are never found in the wild, emitted by GNU
	ld or by any known third-party linking tool.

	Meanwhile, the actually-useful ctf_link feature (albeit not used by ld)
	which lets you remap the names of CTF archive members (so you can end up
	with a parent archive member named something other than ".ctf", still
	contained with all its children in a single .ctf section) had no support
	in objdump or readelf: there was no way to tell them that these members
	were parents, so all the types in the associated child dicts always
	appeared corrupted, referencing nonexistent types from a parent objdump
	couldn't find.

	So adjust --ctf-parent so that rather than taking a section name it
	takes a member name instead (if not specified, the name is ".ctf", which
	is what GNU ld emits).  Because the option was always useless before
	now, this is expected to have no backward-compatibility implications.

	As part of this, we have to slightly adjust the code which skips the
	archive member name if redundant: right now it skips it if it's ".ctf",
	on the assumption that this name will almost always be at the start
	of the objdump output and thus we'll end up with a shared dump
	and then smaller, headed dumps for the per-TU child dicts; but if
	the parent name has been changed, that won't be true any more.

	So change the rules to "members named .ctf which appear first in the
	first have their member name skipped".  Since we now need to count
	members, move from ctf_archive_iter (for which passing in extra
	parameters requires defining a new struct and is clumsy) to
	ctf_archive_next, allowing us to just *call* dump_ctf_archive_member and
	maintain a member count in the obvious way.  In the process we fix a
	tiny difference between readelf and objdump: if a ctf_dump ever failed,
	readelf skipped every later member, while objdump tried to keep going as
	much as it could.  For a dumping tool the former is clearly preferable.

		* objdump.c (usage): --ctf-parent now takes a name, not a section.
		(dump_ctf): Don't open a separate section; use the parent_name in
		ctf_dict_open instead.  Use ctf_archive_next, not ctf_archive_iter,
		so we can pass down a member count.
		(dump_ctf_archive_member): Add the member count; don't return
		anything.  Import parents into children no matter what the
		parent's name, while still avoiding displaying the header for the
		common parent name of ".ctf".
		* readelf.c (usage): Adjust similarly.
		(dump_section_as_ctf): Likewise.
		(dump_ctf_archive_member): Likewise.  Never stop iterating over
		archive members, even if ctf_dump of one member fails.
		* doc/ctf.options.texi: Adjust.

	Fix 'uninstall' target
	This adds some missing code to the 'uninstall' targets in gdb and
	gdbserver.  It also changes gdb's uninstall target so that it no
	longer tries to remove any man page -- this is already done (and more
	correctly) by doc/Makefile.in.

	I tested this with 'make install' followed by 'make uninstall', then
	examining the install tree for regular files.  Only the 'dir' file
	remains, but this appears to just be how 'install-info' is intended to
	work.

	gdb/python: move gdb.Membuf support into a new file
	In a future commit I'm going to be creating gdb.Membuf objects from a
	new file within gdb/python/py*.c.  Currently all gdb.Membuf objects
	are created directly within infpy_read_memory (as a result of calling
	gdb.Inferior.read_memory()).

	Initially I split out the Membuf creation code into a new function,
	and left the new function in gdb/python/py-inferior.c, however, it
	felt a little random that the Membuf creation code should live with
	the inferior handling code.

	So, then I moved all of the Membuf related code out into a new file,
	gdb/python/py-membuf.c, the interface is gdbpy_buffer_to_membuf, which
	wraps an array of bytes into a gdb.Membuf object.

	Most of the code is moved directly from py-inferior.c with only minor
	tweaks to layout and replacing NULL with nullptr, hence, I've left the
	copyright date on py-membuf.c as 2009-2021 to match py-inferior.c.

	Currently, the only user of this code is still py-inferior.c, but in
	later commits this will change.

	There should be no user visible changes after this commit.

	gdb: make disassembler fprintf callback a static member function
	The disassemble_info structure has four callbacks, we have three of
	them as static member functions within gdb_disassembler, the fourth is
	just a global static function.

	However, this fourth callback, is still only used from the
	disassemble_info struct, so there's no real reason for its special
	handling.

	This commit makes fprintf_disasm a static method within

	RISC-V: Added ld testcase for pcgp relaxation.
	Consider the the pcgp-relax-02 testcase,

	        .text
	        .globl _start
	_start:
	.L1:    auipc   a0, %pcrel_hi(data_a)
	.L2:    auipc   a1, %pcrel_hi(data_b)
	        addi    a0, a0, %pcrel_lo(.L1)
	        addi    a1, a1, %pcrel_lo(.L2)

	        .data
	        .word 0x0
	        .globl data_a
	data_a:
	        .word 0x1

	        .section .rodata
	        .globl data_b
	data_b:
	        .word 0x2

	If the first auipc is deleted, but we are still building the pcgp
	table (connect the high and low pcrel relocations), then there is
	an aliasing issue that we need some way to disambiguate which of
	the two symbols we are targeting.  Therefore, Palmer thought of a
	way to use R_RISCV_DELETE to split this into two phases, so we
	could resolve the addresses before creating the ambiguities.

	This patch just add the ld testcase for the above case, in case we
	have changed something but break this.

	RISC-V: Don't separate pcgp relaxation to another relax pass.
	Commit abd20cb637008da9d32018b4b03973e119388a0a and
	ebdcad3fddf6ec21f6d4dcc702379a12718cf0c4 introduced additional
	complexity into the paths run by the RISC-V relaxation pass in order to
	resolve the issue of accurately keeping track of pcrel_hi and pcrel_lo
	pairs. The first commit split up relaxation of these relocs into a pass
	which occurred after other relaxations in order to prevent the situation
	where bytes were deleted in between a pcrel_lo/pcrel_hi pair, inhibiting
	our ability to find the corresponding pcrel_hi relocation from the
	address attached to the pcrel_lo.

	Since the relaxation was split into two passes the 'again' parameter
	could not be used to perform the entire relaxation process again and so
	the second commit added a way to restart ldelf_map_segments, thus
	starting the whole process again.

	Unfortunately this process could not account for the fact that we were
	not finished with the relaxation process so in some cases - such as the
	case where code would not fit in a memory region before the
	R_RISCV_ALIGN relocation was relaxed - sanity checks in generic code
	would fail.

	This patch fixes all three of these concerns by reverting back to a
	system of having only one target relax pass but updating entries in the
	table of pcrel_hi/pcrel_lo relocs every time any bytes are deleted. Thus
	we can keep track of the pairs accurately, and we can use the 'again'
	parameter to restart the entire target relax pass, behaving in the way
	that generic code expects. Unfortunately we must still have an
	additional pass to delay deleting AUIPC bytes to avoid ambiguity between
	pcrel_hi relocs stored in the table after deletion. This pass can only
	be run once so we may potentially miss out on relaxation opportunities
	but this is likely to be rare.

	gdb, gdbserver: make target_waitstatus safe
	I stumbled on a bug caused by the fact that a code path read
	target_waitstatus::value::sig (expecting it to contain a gdb_signal
	value) while target_waitstatus::kind was TARGET_WAITKIND_FORKED.  This
	meant that the active union field was in fact
	target_waitstatus::value::related_pid, and contained a ptid.  The read
	signal value was therefore garbage, and that caused GDB to crash soon
	after.  Or, since that GDB was built with ubsan, this nice error
	message:

	    /home/simark/src/binutils-gdb/gdb/linux-nat.c:1271:12: runtime error: load of value 2686365, which is not a valid value for type 'gdb_signal'

	Despite being a large-ish change, I think it would be nice to make
	target_waitstatus safe against that kind of bug.  As already done
	elsewhere (e.g. dynamic_prop), validate that the type of value read from
	the union matches what is supposed to be the active field.

	 - Make the kind and value of target_waitstatus private.
	 - Make the kind initialized to TARGET_WAITKIND_IGNORE on
	   target_waitstatus construction.  This is what most users appear to do
	   explicitly.
	 - Add setters, one for each kind.  Each setter takes as a parameter the
	   data associated to that kind, if any.  This makes it impossible to
	   forget to attach the associated data.
	 - Add getters, one for each associated data type.  Each getter
	   validates that the data type fetched by the user matches the wait
	   status kind.
	 - Change "integer" to "exit_status", "related_pid" to "child_ptid",
	   just because that's more precise terminology.
	 - Fix all users.

	That last point is semi-mechanical.  There are a lot of obvious changes,
	but some less obvious ones.  For example, it's not possible to set the
	kind at some point and the associated data later, as some users did.
	But in any case, the intent of the code should not change in this patch.

	This was tested on x86-64 Linux (unix, native-gdbserver and
	native-extended-gdbserver boards).  It was built-tested on x86-64
	FreeBSD, NetBSD, MinGW and macOS.  The rest of the changes to native
	files was done as a best effort.  If I forgot any place to update in
	these files, it should be easy to fix (unless the change happens to
	reveal an actual bug).

	Fix ARMv8.4 for hw watchpoint and breakpoint
	Just like my previoius patch for ARMv8.1 and v8.2 (49ecef2a7da2ee9df4),
	this adds ARMv8.4 debug arch as being compatible for hw watchpoint
	and breakpoints.

	Refactor code slightly in nat/aarch64-linux-hw-point.c (aarch64_linux_get_debug_reg_capacity)
	Since the two locations which check the debug arch are the same code currently, it is
	a good idea to factor it out to a new function and just use that function from
	aarch64_linux_get_debug_reg_capacity. This is also the first step to support
	ARMv8.4 debug arch.

	[gdb/tui] Fix breakpoint display functionality
	In commit 81e6b8eb208 "Make tui-winsource not use breakpoint_chain", a loop
	body was transformed into a lambda function body:
	...
	-      for (bp = breakpoint_chain;
	-           bp != NULL;
	-           bp = bp->next)
	+      iterate_over_breakpoints ([&] (breakpoint *bp) -> bool
	...
	and consequently:
	- a continue was replaced by a return, and
	- a final return was added.

	Then in commit 240edef62f0 "gdb: remove iterate_over_breakpoints function", we
	transformed back to a loop body:
	...
	-      iterate_over_breakpoints ([&] (breakpoint *bp) -> bool
	+      for (breakpoint *bp : all_breakpoints ())
	...
	but without reverting the changes that introduced the two returns.

	Consequently, breakpoints no longer show up in the tui source window.

	Fix this by reverting the changes that introduced the two returns.

	tuiterm_env.

	Fix test step-and-next-inline.cc
	The test expect the runto_main to stop at the first line of the function.
	Depending on the optimization level, gdb may stop in the prolog or after
	the prolog at the first line.  To ensure the test stops at the first line
	of main, have it explicitly stop at a break point on the first line of the
	function.

	On PowerPC, the test passes when compiled with no optimization but fails
	with all levels of optimization due to gdb stopping in the prolog.

	Fix latent Ada bug when accessing field offsets
	The "add accessors for field (and call site) location" patch caused a
	gdb crash when running the internal AdaCore testsuite.  This turned
	out to be a latent bug in ada-lang.c.

	The immediate cause of the bug is that find_struct_field
	unconditionally uses TYPE_FIELD_BITPOS.  This causes an assert for a
	dynamic type.

	This patch fixes the problem by doing two things.  First, it changes
	find_struct_field to use a dummy value for the field offset in the
	situation where the offset is not actually needed by the caller.  This
	works because the offset isn't used in any other way -- only as a
	result.

	Second, this patch assures that calls to find_struct_field use a
	resolved type when the offset is needed.  For
	value_tag_from_contents_and_address, this is done by resolving the
	type explicitly.  In ada_value_struct_elt, this is done by passing
	nullptr for the out parameters when they are not needed (the second
	call in this function already uses a resolved type).

	Note that, while we believe the parent field probably can't occur at a
	variable offset, the patch still updates this code path, just in case.

	I've updated an existing test case to reproduce the crash.
	I'm checking this in.

	Re: PR27625, powerpc64 gold __tls_get_addr calls
	My previous PR27625 patch had a problem or two.  For one, the error
	"__tls_get_addr call lacks marker reloc" on processing some calls
	before hitting a call without markers typically isn't seen.  Instead a
	gold assertion fails.  Either way it would be a hard error, which
	triggers on a file contained in libphobos.a when running the gcc
	testsuite.  A warning isn't even appropriate since the call involved
	is one built by hand without any of the arg setup relocations that
	might result in linker optimisation.

	So this patch reverts most of commit 0af4fcc25dd5, instead entirely
	ignoring the problem of mis-optimising old-style __tls_get_addr calls
	without marker relocs.  We can't handle them gracefully without
	another pass over relocations before decisions are made about GOT
	entries in Scan::global or Scan::local.  That seems too costly, just
	to link object files from 2009.  What's more, there doesn't seem to be
	any way to allow the libphobos explicit __tls_get_addr call, but not
	old TLS sequences without marker relocs.  Examining instructions
	before the __tls_get_addr call is out of the question: program flow
	might reach the call via a branch.  Putting an R_PPC64_TLSGD marker
	with zero sym on the call might be a solution, but current linkers
	will then merrily optimise away the call!

	CTF: incorrect underlying type setting for enumeration types
	A bug was filed against the incorrect underlying type setting for
	an enumeration type, which was caused by a copy and paste error.
	This patch fixes the problem by setting it by calling objfile_int_type,
	which was originally dwarf2_per_objfile::int_type, with ctf_type_size bits.
	Also add error checking on ctf_func_type_info call.

	PR28459, readelf issues bogus warning
	I'd missed the fact that the .debug_rnglists dump doesn't exactly
	display the contents of the section.  Instead readelf rummages through
	.debug_info looking for DW_AT_ranges entries, then displays the
	entries in .debug_rnglists pointed at, sorted.  A simpler dump of the
	actual section contents might be more useful and robust, but it was
	likely done that way to detect overlap and holes.

	Anyway, the headers in .debug_rnglists besides the first are ignored,
	and limiting to the unit length of the first header fails if there is
	more than one unit.

	[gdb/exp] Improve <error reading variable> message
	When printing a variable x in a subroutine foo:

	gdb: improve error reporting from the disassembler
	If the libopcodes disassembler returns a negative value then this
	indicates that the disassembly failed for some reason.  In disas.c, in
	the function gdb_disassembler::print_insn we can see how this is
	handled; when we get a negative value back, we call the memory_error
	function, which throws an exception.

	The problem here is that the address used in the memory_error call is
	gdb_disassembler::m_err_memaddr, which is set in
	gdb_disassembler::dis_asm_memory_error, which is called from within
	the libopcodes disassembler through the
	disassembler_info::memory_error_func callback.

	However, for this to work correctly, every time the libopcodes
	disassembler returns a negative value, the libopcodes disassembler
	must have first called the memory_error_func callback.

	My first plan was to make m_err_memaddr a gdb::optional, and assert
	that it always had a value prior to calling memory_error, however, a
	quick look in opcodes/*-dis.c shows that there _are_ cases where a
	negative value is returned without first calling the memory_error_func
	callback, for example in arc-dis.c and cris-dis.c.

	Now, I think that a good argument can be made that these disassemblers
	must therefore be broken, except for the case where we can't read
	memory, we should always be able to disassemble the memory contents to
	_something_, even if it's just '.word 0x....'.  However, I certainly
	don't plan to go and fix all of the disassemblers.

	What I do propose to do then, is make m_err_memaddr a gdb::optional,
	but now, instead of always calling memory_error, I add a new path
	which just calls error complaining about an unknown error.  This new
	path is only used if m_err_memaddr doesn't have a value (indicating
	that the memory_error_func callback was not called).

	To test this I just augmented one of the disassemblers to always
	return -1, before this patch I see this:

	  Dump of assembler code for function main:
	     0x000101aa <+0>:	Cannot access memory at address 0x0

	And after this commit I now see:

	  Dump of assembler code for function main:
	     0x000101aa <+0>:	unknown disassembler error (error = -1)

	This doesn't really help much, but that's because there's no way to
	report non memory errors out of the disasembler, because, it was not
	expected that the disassembler would ever report non memory errors.

	[gdb/testsuite] Fix test name in gdb.python/python.exp
	When running test-case gdb.python/python.exp, we have:
	...
	PASS: gdb.python/python.exp: starti via gdb.execute, not from tty
	PASS: gdb.python/python.exp: starti via interactive input
	...

	The two tests are instances of the same test, with different values for
	starti command argument from_tty, so it's strange that the test names are so
	different.

	This is due to using a gdb_test nested in a gdb_test_multiple, with the inner
	one using a different test name than the outer one.  [ That could still make
	sense if both produced passes, but that's not the case here. ]

	Fix this by using $gdb_test_name, such that we have:
	...
	PASS: gdb.python/python.exp: starti via gdb.execute, not from tty
	PASS: gdb.python/python.exp: starti via gdb.execute, from tty

	[gdb/testsuite] Fix gdb.base/batch-exit-status.exp with native-gdbserver
	When running test-case gdb.base/batch-exit-status.exp with target board

	...

	FAIL: gdb.base/batch-exit-status.exp: 1x: \
	  No such file or directory: [lindex $result 3] == $expect_status
	...

	As in commit a02a90c114c "[gdb/testsuite] Set sysroot earlier in
	local-board.exp", the problem is the use of -ex for
	"set auto-connect-native-target off", which makes that the last command to

	Fix this by using -iex instead.

	[ARM] Add support for M-profile MVE extension
	This patch adds support for the M-profile MVE extension, which includes the
	following:

	- New M-profile XML feature m-profile-mve
	- MVE vector predication status and control register (VPR)
	- p0 pseudo register (contained in the VPR)
	- q0 ~ q7 pseudo vector registers
	- New feature bits
	- Documentation update

	Pseudo register p0 is the least significant bits of vpr and can be accessed
	as $p0 or displayed through $vpr.  For more information about the register
	layout, please refer to [1].

	The q0 ~ q7 registers map back to the d0 ~ d15 registers, two d registers
	per q register.

	[ARM] Refactor pseudo register numbering
	The pseudo register handling for ARM uses some hardcoded constants to
	determine types and names.  In preparation to the upcoming MVE support
	patch (that will add another pseudo register), this patch refactors and
	reorganizes things in order to simplify handling of future pseudo registers.

	We keep track of the first pseudo register number in a group and the number of
	pseudo registers in that group.

	Right now we only have the S and Q pseudo registers.

	[ARM] Small refactoring of arm gdbarch initialization
	This is in preparation to MVE support, where we will define another
	pseudo register. We need to define the pseudo register numbers *after*
	accounting for all the registers in the XML description, so move
	the call to tdesc_use_registers up.

	If we don't do it, GDB's register count won't consider registers contained
	in the XML but ignored by GDB, throwing the register numbering off.

	[ARM] Refactor some constants
	In preparation for the MVE extension patch, this one refactors some of
	the register-related constants we have for ARM.

	Basically I'm separating counting constants from numbering constants.

	For example, ARM_A1_REGNUM is a numbering constant, whereas ARM_NUM_ARG_REGS
	is a counting constant.

	[gdb/testsuite] Fix FAIL in gdb.mi/mi-var-child-f.exp
	When running test-case gdb.mi/mi-var-child-f.exp on openSUSE Tumbleweed
	(with glibc 2.34) I run into:
	...
	(gdb) ^M
	PASS: gdb.mi/mi-var-child-f.exp: mi runto prog_array
	Expecting: ^(-var-create array \* array[^M

	The problem is that the name array is used both:
	- as the name for a local variable
	- as the name of a type in glibc, in file malloc/dynarray-skeleton.c, as included
	  by nss/nss_files/files-hosts.c.

	Fix this by ignoring the shared lib symbols.

	Likewise in a couple of other fortran tests.

	Tested on x86_64-linux.

	[gdb/testsuite] Fix double debug info in gdb.dwarf2/dw2-ref-missing-frame.exp
	A mistake slipped in in commit a5ea23036d8 "[gdb/testsuite] Use function_range
	in gdb.dwarf2/dw2-ref-missing-frame.exp".

	Before the commit the main file was compiled with debug info, and the two
	others not:
	...
	if {[prepare_for_testing_full "failed to prepare" \
	        [list $testfile {} $srcfile {} $srcfuncfile {} \
	             $srcmainfile debug]]} {
	...

	After the commit, all were compiled with debug info, and consequently, there
	are two versions of debug info for $srcfuncfile.  This shows up as a FAIL when
	running the test-case with target boards readnow and cc-with-debug-names.

	Fix this by using prepare_for_testing_full, as before.

	Tested on x86_64-linux.

	Fixes: a5ea23036d8 ("[gdb/testsuite] Use function_range in
	       gdb.dwarf2/dw2-ref-missing-frame.exp")

	[gdb/testsuite] Handle readnow in ensure_gdb_index
	When running test-case gdb.base/with-mf.exp with target board readnow, I run
	into:
	...
	FAIL: gdb.base/with-mf.exp: check if index present
	...
	This is since commit 6010fb0c49e "[gdb/testsuite] Fix full buffer in
	gdb.rust/dwindex.exp".

	Before that commit, the proc ensure_gdb_index would treat the line:
	...
	.gdb_index: faked for "readnow"^M
	...
	as proof that an index is already present (which is incorrect).

	Now, instead it generates aforementioned FAIL and continues to generate an
	index.

	Fix this by explicitly handling the readnow case in proc ensure_gdb_index,
	such that we bail out instead.

	Tested on x86_64-linux.

	[gdb/testsuite] Fix gdb.dwarf2/gdb-add-index-symlink.exp
	The test-case gdb.dwarf2/gdb-add-index-symlink.exp interpretes a failure to
	add an index as a failure to add an index for a symlink:
	...
	if { [ensure_gdb_index $symlink] == -1 } {
	    fail "Unable to call gdb-add-index with a symlink to a symfile"
	    return -1
	}
	...

	However, it's possible that the gdb-add-index also fails with a regular
	file.  Add a check for that situation.

	Tested on x86_64-linux.

	[gdb] Make execute_command_to_string return string on throw
	The pattern for using execute_command_to_string is:
	...
	  std::string output;
	  output = execute_fn_to_string (fn, term_out);
	...

	This results in a problem when using it in a try/catch:
	...
	  try
	    {
	      output = execute_fn_to_string (fn, term_out)
	    }
	  catch (const gdb_exception &e)
	    {
	      /* Use output.  */
	    }
	...

	If an expection was thrown during execute_fn_to_string, then the output
	remains unassigned, while it could be worthwhile to known what output was
	generated by gdb before the expection was thrown.

	Fix this by returning the string using a parameter instead:
	...
	  execute_fn_to_string (output, fn, term_out)
	...

	Also add a variant without string parameter, to support places where the
	function is used while ignoring the result:
	...
	  execute_fn_to_string (fn, term_out)
	...

	Tested on x86_64-linux.

	[gdb/testsuite] Add check-readmore
	Consider the gdb output:
	...
	27        return SYSCALL_CANCEL (nanosleep, requested_time, remaining);^M
	(gdb) ^M
	Thread 2 "run-attach-whil" stopped.^M
	...

	When trying to match the gdb prompt using gdb_test which uses '$gdb_prompt $',
	it may pass or fail.

	This sort of thing needs to be fixed (see commit b0e2f96b56b), but there's
	currently no way to reliably find this type of FAILs.

	We have check-read1, but that one actually make the test pass reliably.

	We need something like the opposite of check-read1: something that makes
	expect read a bit slower, or more exhaustively.

	Add a new test target check-readmore that implements this.

	There are two methods of implementing this in read1.c:
	- the first method waits a bit before doing a read
	- the second method does a read and then decides whether to
	  return or to wait a bit and do another read, and so on.

	The second method is potentially faster, has less risc of timeout and could
	potentially detect more problems.  The first method has a simpler
	implementation.

	The second method is enabled by default.  The default waiting period is 10
	miliseconds.

	The first method can be enabled using:
	...
	$ export READMORE_METHOD=1
	...
	and the waiting period can be specified in miliseconds using:
	...
	$ export READMORE_SLEEP=9
	...

	Also a log file can be specified using:
	...
	$ export READMORE_LOG=$(pwd -P)/LOG
	...

	Tested on x86_64-linux.

	Testing with check-readmore showed these regressions:
	...
	FAIL: gdb.base/bp-cmds-continue-ctrl-c.exp: run: stop with control-c (continue)
	FAIL: gdb.base/bp-cmds-continue-ctrl-c.exp: attach: stop with control-c (continue)
	...

	I have not been able to find a problem in the test-case, and I think it's the
	nature of both the test-case and readmore that makes it run longer.  Make
	these pass by increasing the alarm timeout from 60 to 120 seconds.

	gdb: add accessors for field (and call site) location
	Add accessors for the various location values in struct field.  This
	lets us assert that when we get a location value of a certain kind (say,
	bitpos), the field's location indeed contains a value of that kind.

	Remove the SET_FIELD_* macros, instead use the new setters directly.
	Update the FIELD_* macros used to access field locations to go through
	the getters.  They will be removed in a subsequent patch.

	There are places where the FIELD_* macros are used on call_site_target
	structures, because it contains members of the same name (loc_kind and
	loc).  For now, I have replicated the getters/setters in
	call_site_target.  But we could perhaps eventually factor them in a
	"location" structure that can be used at both places.

	Note that the field structure, being zero-initialized, defaults to a
	bitpos location with value 0.  While writing this patch, I tried to make
	it default to an "unset" location, to catch places where we would miss
	setting a field's location.  However, I found that some places relied on
	the default being "bitpos 0", so I left it as-is.  This change could
	always be done as follow-up work, making these places explicitly set the
	"bitpos 0" location.

	I found two issues to fix:

	 - I got some failures in the gdb.base/infcall-nested-structs-c++.exp
	   test.  They were caused by two functions in amd64-tdep.c using
	   TYPE_FIELD_BITPOS before checking if the location is of the bitpos
	   kind, which they do indirectly through `field_is_static`.  Simply
	   move getting the bitpos below the field_is_static call.

	 - I got a failure in gdb.xml/tdesc-regs.exp.  It turns out that in
	   make_gdb_type_enum, we set enum field values using SET_FIELD_BITPOS,
	   and later access them through FIELD_ENUMVAL.  Fix that by using
	   set_loc_enumval to set the value.

	PR28423, use-after-free in objdump
	XCOFF archives use a bi-directional linked list for file members.  So
	one member points to both the previous member and the next member.
	Members may not be sequentially ordered in the file.  This of course
	is over-engineered nonsense and an attractive target for fuzzers.
	(There is even a free list of members!)  The testcase in PR28423 is an
	XCOFF archive with one member pointing to itself, which results in
	lots of bad behaviour.  For example, "ar t" never terminates.

	The use-after-free with "objdump -r" happens like this:  The first
	archive element is opened, its symbols are read and "canonicalized"
	for objdump, then relocations are read and printed.  Those relocations
	use the canonicalized symbols, and also happen to be cached by the
	coff bfd backend support.  objdump frees the symbols.  The next
	archive element is then opened.  This must be done before the first
	element is closed, because finding the next element uses data held in
	the currect element.  Unfortunately the next element happens to be the
	original, so we aren't opening, we're reopening a bfd which has cached
	data.  When the relocations are printed they use the cached copy
	containing references to the freed canonical symbols.

	This patch adds a little sanity checking to the XCOFF "open next
	archive file" support, so that it rejects archive members pointing at
	themselves.  That is sufficient to cure this problem.  Anything more
	is overkill.  If someone deliberately fuzzes an XCOFF archive with an
	element loop then reports an "ar" bug when it runs forever, they will
	find their bug report closed WONTFIX.

	Most of the output is related to controlling the tui screen, but that does
	not give a top-level sense of how the test-case progresses.

	Put differently: a lot of bandwith is used to describe how we arrive at a
	certain tui screen state.  But we don't actually always show the state we
	arrive at, unless there's a FAIL.

	And if there's say, a PASS that should actually be FAILing, it's hard to
	detect.

	Fix this by:
	- dropping the -log on the call to verbose in _log.  We still can get the
	  same info back using runtest -v.
	- dumping the screen or box that we're checking, also when the test passes.

	gdb: Remove deprecated assertion in setting::get
	The commit 702991711a91bd47b209289562843a11e7009396 (gdb: Have setter
	and getter callbacks for settings) makes it possible for a setting not
	to be backed by a memory buffer but use callback functions instead to
	retrieve or set the setting's value.

	An assertion was not properly updated to take into account that the
	m_var member (which points to a memory buffer, if used) might be nullptr
	if the setting uses callback functions.  If the setting is backed by a
	memory buffer, the m_var has to be non nullptr, which is already checked
	before the pointer is dereferenced.

	This commit removes this assertion as it is not valid anymore.

	value_zero is called in expression evaluation to wrap a type in a
	non-eval context.  It seems senseless to allocate a buffer in these
	cases.

	A new 'is_zero' flag is added so we can preserve the existing
	assertions in value_fetch_lazy.

	A subsequent patch will add a test where creating a zero value would
	fail, due to the variable size check.  However, the contents of this
	value are never needed, and so creating a lazy value avoids the error
	case.

	Add lval_funcs::is_optimized_out
	This adds an is_optimized_out function pointer to lval_funcs, and
	changes value_optimized_out to call it.  This new function lets gdb
	determine if a value is optimized out without necessarily fetching the
	value.  This is needed for a subsequent patch, where an attempt to
	access a lazy value would fail due to the value size limit -- however,
	the access was only needed to determine the optimized-out state.

	gdb/python: fix memory leak in python inferior code
	When a user creates a gdb.Inferior object for the first time a new
	Python object is created.  This object is then cached within GDB's
	inferior object using the registry mechanism (see
	inferior_to_inferior_object in py-inferior.c, specifically the calls
	to inferior_data and set_inferior_data).

	The Python Reference to the gdb.Inferior object held within the real
	inferior object ensures that the reference count on the Python
	gdb.Inferior object never reaches zero while the GDB inferior object
	continues to exist.

	At the same time, the gdb.Inferior object maintains a C++ pointer back
	to GDB's real inferior object.  We therefore end up with a system that
	looks like this:

	                   Python Reference
	                         |
	                         |
	    .----------.         |          .--------------.
	    |          |------------------->|              |
	    | inferior |                    | gdb.Inferior |
	    |          |<-------------------|              |
	    '----------'         |          '--------------'
	                         |
	                         |
	                    C++ Pointer

	When GDB's inferior object is deleted (say the inferior exits) then
	py_free_inferior is called (thanks to the registry system), this
	function looks up the Python gdb.Inferior object and sets the C++
	pointer to nullptr and finally reduces the reference count on the
	Python gdb.Inferior object.

	If at this point the user still holds a reference to the Python
	gdb.Inferior object then nothing happens.  However, the gdb.Inferior
	object is now in the non-valid state (see infpy_is_valid in
	py-inferior.c), but otherwise, everything is fine.

	However, if there are no further references to the Python gdb.Inferior
	object, or, once the user has given up all their references to the
	gdb.Inferior object, then infpy_dealloc is called.

	This function currently checks to see if the inferior pointer within
	the gdb.Inferior object is nullptr or not.  If the pointer is nullptr
	then infpy_dealloc immediately returns.

	Only when the inferior point in the gdb.Inferior is not nullptr do
	we (a) set the gdb.Inferior reference inside GDB's inferior to
	nullptr, and (b) call the underlying Python tp_free function.

	There are a number things wrong here:

	  1.  The Python gdb.Inferior reference within GDB's inferior object
	  holds a reference count, thus, setting this reference to nullptr
	  without first decrementing the reference count would leak a
	  reference, however...

	  2. As GDB's inferior holds a reference then infpy_dealloc will never
	  be called until GDB's inferior object is deleted.  Deleting a GDB
	  inferior ohject calls py_free_inferior, and so gives up the
	  reference.  At this point there is no longer a need to call
	  set_inferior_data to set the field back to NULL, that field must
	  have been cleared in order to get the reference count to zero, which
	  means...

	  3. If we know that py_free_inferior must be called before
	  infpy_dealloc, then we know that the inferior pointer in
	  gdb.Inferior will always be nullptr when infpy_dealloc is called,
	  this means that the call to the underlying tp_free function will
	  always be skipped.  Skipping this call will cause Python to leak the
	  memory associated with the gdb.Inferior object, which is what we
	  currently always do.

	Given all of the above, I assert that the C++ pointer within
	gdb.Inferior will always be nullptr when infpy_dealloc is called.
	That's what this patch does.

	I wrote a test for this issue making use of Pythons tracemalloc
	module, which allows us to spot this memory leak.

	gdb/python: add a new gdb_exiting event
	Add a new event, gdb.events.gdb_exiting, which is called once GDB
	decides it is going to exit.

	This event is not triggered in the case that GDB performs a hard
	abort, for example, when handling an internal error and the user
	decides to quit the debug session, or if GDB hits an unexpected,
	fatal, signal.

	This event is triggered if the user just types 'quit' at the command
	prompt, or if GDB is run with '-batch' and has processed all of the
	required commands.

	The new event type is gdb.GdbExitingEvent, and it has a single
	attribute exit_code, which is the value that GDB is about to exit
	with.

	The event is triggered before GDB starts dismantling any of its own
	internal state, so, my expectation is that most Python calls should
	work just fine at this point.

	When considering this functionality I wondered about using the
	'atexit' Python module.  However, this is triggered when the Python
	environment is shut down, which is done from a final cleanup.  At
	this point we don't know for sure what other GDB state has already
	been cleaned up.

	gdb/python: update events test to handle missing exit_code
	The test gdb.python/py-events.exp sets up a handler for the gdb.exited
	event.  Unfortunately the handler is slightly broken, it assumes that
	the exit_code attribute will always be present.  This is not always
	the case.

	In a later commit I am going to add more tests to py-events.exp test
	script, and in so doing I expose the bug in our handling of gdb.exited
	events.

	Just to be clear, GDB itself is fine, it is the test that is not
	written correctly according to the Python Events API.

	So, in this commit I fix the Python code in the test, and extend the
	test case to exercise more paths through the Python code.

	Additionally, I noticed that the gdb.exited event is used as an
	example in the documentation for how to write an event handler.
	Unfortunately the same bug that we had in our test was also present in
	the example code in the manual.

	So I've fixed that too.

	After this commit there is no functional change to GDB.

	[gdb/build] Add CXX_DIALECT to CXX
	Say we use a gcc version that (while supporting c++11) does not support c++11
	by default, and needs an -std setting to enable it.

	If gdb would use the default AX_CXX_COMPILE_STDCXX from autoconf-archive, then
	we'd have:
	...
	CXX="g++ -std=gnu++11"
	...

	That mechanism however has the following problem (quoting from commit
	0bcda685399):
	...
	the top level Makefile passes CXX down to subdirs, and that overrides whatever
	gdb/Makefile may set CXX to.  The result would be that a make invocation from
	the build/gdb/ directory would use "g++ -std=gnu++11" as expected, while a
	make invocation at the top level would not.
	...

	Commit 0bcda685399 fixes this by using a custom AX_CXX_COMPILE_STDCXX which
	does:
	...
	CXX=g++
	CXX_DIALECT=-std=gnu++11
	...

	The problem reported in PR28318 is that using the custom instead of the
	default AX_CXX_COMPILE_STDCXX makes the configure test for std::thread
	support fail.

	We could simply add $CXX_DIALECT to the test for std::thread support, but
	that would have to be repeated for each added c++ support test.

	Instead, fix this by doing:
	...
	CXX="g++ -std=gnu++11"
	CXX_DIALECT=-std=gnu++11
	...

	This is somewhat awkward, since it results in -std=gnu++11 occuring twice in
	some situations:
	...
	$ touch src/gdb/dwarf2/read.c
	$ ( cd build/gdb; make V=1 dwarf2/read.o )
	g++-4.8 -std=gnu++11 -x c++ -std=gnu++11 ...
	...

	However, both settings are needed:
	 - the switch in CXX for the std::thread tests (and other tests)
	 - the switch in CXX_DIALECT so it can be appended in Makefiles, to
	   counteract the fact that the top-level Makefile overrides CXX

	The code added in gdb/ax_cxx_compile_stdcxx.m4 is copied from the default
	AX_CXX_COMPILE_STDCXX from autoconf-archive.

	Tested on x86_64-linux.

	[gdb/symtab] Use unrelocated addresses in call_site
	Consider test-case gdb.trace/entry-values.exp with target board
	unix/-fPIE/-pie.

	Using this command we have an abbreviated version, and can see the correct
	@entry values for foo:
	...
	$ gdb -q -batch outputs/gdb.trace/entry-values/entry-values \
	  -ex start \
	  -ex "break foo" \
	  -ex "set print entry-values both" \
	  -ex continue
	Temporary breakpoint 1 at 0x679

	Temporary breakpoint 1, 0x0000555555554679 in main ()
	Breakpoint 2 at 0x55555555463e

	Breakpoint 2, 0x000055555555463e in foo (i=0, i@entry=2, j=2, j@entry=3)
	...

	Now, let's try the same again, but run directly to foo rather than stopping at
	main:
	...
	$ gdb -q -batch outputs/gdb.trace/entry-values/entry-values \
	  -ex "break foo" \
	  -ex "set print entry-values both" \
	  -ex run
	Breakpoint 1 at 0x63e

	Breakpoint 1, 0x000055555555463e in foo (i=0, i@entry=<optimized out>, \
	  j=2, j@entry=<optimized out>)
	...

	So, what explains the difference?  Noteworthy, this is a dwarf assembly
	test-case, with debug info for foo and bar, but not for main.

	In the first case:
	- we run to main
	- this does not trigger expanding debug info, because there's none for main
	- we set a breakpoint at foo
	- this triggers expanding debug info.  Relocated addresses are used in
	  call_site info (because the exec is started)
	- we continue to foo, and manage to find the call_site info

	In the second case:
	- we set a breakpoint at foo
	- this triggers expanding debug info.  Unrelocated addresses are used in
	  call_site info (because the exec is not started)
	- we run to foo
	- this triggers objfile_relocate1, but it doesn't update the call_site
	  info addresses
	- we don't manage to find the call_site info

	We could fix this by adding the missing call_site relocation in
	objfile_relocate1.

	This solution however is counter-trend in the sense that we're trying to
	work towards the situation where when starting two instances of an executable,
	we need only one instance of debug information, implying the use of
	unrelocated addresses.

	So, fix this instead by using unrelocated addresses in call_site info.

	Tested on x86_64-linux.

	This fixes all remaining unix/-fno-PIE/-no-pie vs unix/-fPIE/-pie
	regressions, like f.i. PR24892.

	[gdb/symtab] Add call_site_eq and call_site_hash
	In commit b4c919f7525 "[gdb/symtab] Fix htab_find_slot call in
	read_call_site_scope" , I removed the comment:
	...
	It must be the first field as we overload core_addr_hash and core_addr_eq for
	it.
	...
	for field pc of struct call_site.

	However, this was not tested, and when indeed moving field pc to the second
	location, we run into a testsuite failure in gdb.trace/entry-values.exp.

	This is caused by core_addr_eq (the eq_f function for the htab) being
	called with a pointer to the pc field (as passed into htab_find_slot) and a
	pointer to a hash table element.  Now that pc is no longer the first field,
	the pointer to hash table element no longer points to the pc field.

	This could be fixed by simply reinstating the comment, but we're trying to
	get rid of this kind of tricks that make refactoring more difficult.

	Instead, fix this by:
	- reverting commit b4c919f7525, apart from the comment removal, such that
	  we're passing a pointer to element to htab_find_slot
	- updating the htab_find_slot call in compunit_symtab::find_call_site
	  in a similar manner
	- adding a call_site_eq and call_site_hash, and using these in the hash table
	  instead of core_addr_eq and core_addr_hash.

	Tested on x86_64-linux, both with and without a trigger patch that moves pc to
	the second location in struct call_site.

	gdbsupport: remove attempt to define TARGET_WORD_SIZE
	In the gdbsupport configure.ac file, there is an attempt to define
	TARGET_WORD_SIZE.  This is done by running grep on the file
	../bfd/bfd-in3.h.

	The problem with this is, the file bfd-in3.h is generated into the bfd
	build directory when bfd is configured, and there is no dependency
	between the gdbsupport module and the bfd module, so, for example, if
	I do:

	  $ ../src/configure
	  $ make all-gdbsupport

	Then bfd will neither be configured, or built.  In this case
	TARGET_WORD_SIZE ends up being defined, but with no value because the
	grep on bfd-in3.h fails.

	However, it turns out that this doesn't matter; we don't actually use
	TARGET_WORD_SIZE anywhere.

	My proposal in this commit is to just remove the definition of
	TARGET_WORD_SIZE, the alternative would be to add a dependency between
	configure-gdbsupport and configure-bfd into Makefile.def, but adding a
	dependency for something we don't need seems pretty pointless.

	gdb: Setting setter return a bool to tell if the value changed
	GDB can notify observers when a parameter is changed.

	To do that, do_set_command (in gdb/cli/cli-setshow.c) compares the new
	value against the old one before updating it, and based on that notifies
	observers.  This looks like something like:

	    int valuechanged = 0;
	    switch (cmd->var.type ())
	    {
	    case var_integer:
	      {
	        LONGEST new_val = parse_and_eval_long (arg)
	        if (new_val != cmd->var.get<int> ())
	        {
	          cmd->var.get<int> (new_val);
	          value_changes = 1;
	        }
	      }
	    case var_uinteger:
	    case var_zuinteger:
	      {
	        unsigned int val
	          = parse_cli_var_uinteger (c->var->type (), &arg, true);
	        if (c->var->get<unsigned int> () != val)
	          {
	            c->var->set<unsigned int> (val);
	            option_changed = true;
	          }
	      }
	    case...
	      /* And so on for all possible var_types.  */
	    }

	This comparison is done for each possible var_type, which leads to
	unnecessary logic duplication.

	In this patch I propose to move all those checks in one place within the
	setting setter method.  This limits the code duplication and simplifies
	the do_set_command implementation.

	This patch also changes slightly the way a value change is detected.
	Instead of comparing the user provided value against the current value
	of the setting, we compare the value of the setting before and after the
	set operation.  This is meant to handle edge cases where trying to set
	an unrecognized value would be equivalent to a noop (the actual value
	remains unchanged).  Doing this requires that the original value needs
	to be copied before the update, which can be non trivial for
	std::string.

	There should be no user visible change introduced by this commit.

	Tested on x86_64 GNU/Linux.

	gdb: Have setter and getter callbacks for settings
	The main motivation behind this improvement is to help the
	implementation of a patch Simon Marchi is preparing to fix a bug when
	MI or Python try to access parameters that are inferior dependent (see
	PR/28085).

	This commit extends the previous ones, which introduces the setting
	object to represent a static variable whose value can be set or shown
	with the appropriate commands.  This patch proposes that a setting can
	either contain a pointer to a static variable holding a setting, or
	pointers to a pair of setter and getter callback functions.

	The callbacks functions can be used to retrieve or change the value with
	custom logic.  This is useful when the source of truth for a given
	setting is not contained in the variable pointed to by the setting
	instance.

	Given that the callback function call is hidden within the setting
	abstraction introduced earlier, none of the sites accessing the setting
	needs to be updated.  The registered getter or setter is used whatever
	the way to access it is (through MI, Python, Guile, the "with" command
	and the $_gdb_setting / $_gdb_setting_str convenience functions).

	All the add_setshow_*_cmd are given a new overload that will accept the
	pair of function pointers (set / get functions) instead of the pointer
	to a global variable.

	Tested on GNU/Linux x86_64 with no regression observed.

	gdb: make string-like set show commands use std::string variable
	String-like settings (var_string, var_filename, var_optional_filename,
	var_string_noescape) currently take a pointer to a `char *` storage
	variable (typically global) that holds the setting's value.  I'd like to
	"mordernize" this by changing them to use an std::string for storage.

	An obvious reason is that string operations on std::string are often
	easier to write than with C strings.  And they avoid having to do any
	manual memory management.

	Another interesting reason is that, with `char *`, nullptr and an empty
	string often both have the same meaning of "no value".  String settings
	are initially nullptr (unless initialized otherwise).  But when doing
	"set foo" (where `foo` is a string setting), the setting now points to
	an empty string.  For example, solib_search_path is nullptr at startup,
	but points to an empty string after doing "set solib-search-path".  This
	leads to some code that needs to check for both to check for "no value".
	Or some code that converts back and forth between NULL and "" when
	getting or setting the value.  I find this very error-prone, because it
	is very easy to forget one or the other.  With std::string, we at least
	know that the variable is not "NULL".  There is only one way of
	representing an empty string setting, that is with an empty string.

	I was wondering whether the distinction between NULL and "" would be
	important for some setting, but it doesn't seem so.  If that ever
	happens, it would be more C++-y and self-descriptive to use
	optional<string> anyway.

	Actually, there's one spot where this distinction mattered, it's in
	init_history, for the test gdb.base/gdbinit-history.exp.  init_history
	sets the history filename to the default ".gdb_history" if it sees that
	the setting was never set - if history_filename is nullptr.  If
	history_filename is an empty string, it means the setting was explicitly
	cleared, so it leaves it as-is.  With the change to std::string, this
	distinction doesn't exist anymore.  This can be fixed by moving the code
	that chooses a good default value for history_filename to
	_initialize_top.  This is ran before -ex commands are processed, so an
	-ex command can then clear that value if needed (what
	gdb.base/gdbinit-history.exp tests).

	Another small improvement, in my opinion is that we can now easily
	give string parameters initial values, by simply initializing the global
	variables, instead of xstrdup-ing it in the _initialize function.

	In Python and Guile, when registering a string-like parameter, we
	allocate (with new) an std::string that is owned by the param_smob (in
	Guile) and the parmpy_object (in Python) objects.

	This patch started by changing all relevant add_setshow_* commands to
	take an `std::string *` instead of a `char **` and fixing everything
	that failed to build.  That includes of course all string setting
	variable and their uses.

	string_option_def now uses an std::string also, because there's a
	connection between options and settings (see
	add_setshow_cmds_for_options).

	The add_path function in source.c is really complex and twisted, I'd
	rather not try to change it to work on an std::string right now.
	Instead, I added an overload that copies the std:string to a `char *`
	and back.  This means more copying, but this is not used in a hot path
	at all, so I think it is acceptable.

	gdb: Introduce setting construct within cmd_list_element
	cmd_list_element can contain a pointer to data that can be set and / or
	shown.  This is achieved with the void* VAR member which points to the
	data that can be accessed, while the VAR_TYPE member (of type enum
	var_types) indicates how to interpret the data pointed to.

	With this pattern, the user of the cmd_list_element needs to know what
	is the storage type associated with a given VAR_TYPES in order to do
	the proper casting.  No automatic safeguard is available to prevent
	miss-use of the pointer.  Client code typically looks something like:

		switch (c->var_type)
		{
		  case var_zuinteger:
		    unsigned int v = *(unsigned int*) c->var;
		    ...
		    break;
		  case var_boolean:
		    bool v = *(bool *) c->var;
		    ...
		    break;
		  ...
		}

	This patch proposes to add an abstraction around the var_types and void*
	pointer pair.  The abstraction is meant to prevent the user from having
	to handle the cast and verify that the data is read or written as a type
	that is coherent with the setting's var_type.  This is achieved by
	introducing the struct setting which exposes a set of templated get /
	set member functions.  The template parameter is the type of the
	variable that holds the referred variable.

	Using those accessors allows runtime checks to be inserted in order to
	ensure that the data pointed to has the expected type.  For example,
	instantiating the member functions with bool will yield something
	similar to:

		const bool &get<bool> () const
		{
		  gdb_assert (m_var_type == var_boolean);
		  gdb_assert (m_var != nullptr);
		  return *static_cast<bool *> (m_var);
		}
		void set<bool> (const bool &var)
		{
		  gdb_assert (m_var_type == var_boolean);
		  gdb_assert (m_var != nullptr);
		  *static_cast<bool *> (m_var) = var;
		}

	Using the new abstraction, our initial example becomes:

		switch (c->var_type)
		{
		  case var_zuinteger:
		    unsigned int v = c->var->get<unsigned int> ();
		    ...
		    break;
		  case var_boolean:
		    bool v = c->var->get<bool> ();
		    ...
		    break;
		  ...
		}

	While the call site is still similar, the introduction of runtime checks
	help ensure correct usage of the data.

	In order to avoid turning the bulk of add_setshow_cmd_full into a
	templated function, and following a suggestion from Pedro Alves, a
	setting can be constructed from a pre validated type erased reference to
	a variable.  This is what setting::erased_args is used for.

	Introducing an opaque abstraction to describe a setting will also make
	it possible to use callbacks to retrieve or set the value of the setting
	on the fly instead of pointing to a static chunk of memory.  This will
	be done added in a later commit.

	Given that a cmd_list_element may or may not reference a setting, the
	VAR and VAR_TYPES members of the struct are replaced with a
	gdb::optional<setting> named VAR.

	Few internal function signatures have been modified to take into account
	this new abstraction:

	-The functions value_from_setting, str_value_from_setting and
	 get_setshow_command_value_string used to have a 'cmd_list_element *'
	 parameter but only used it for the VAR and VAR_TYPE member. They now
	 take a 'const setting &' parameter instead.
	- Similarly, the 'void *' and a 'enum var_types' parameters of
	  pascm_param_value and gdbpy_parameter_value have been replaced with a
	  'const setting &' parameter.

	No user visible change is expected after this patch.

	Tested on GNU/Linux x86_64, with no regression noticed.

	sim: filter out SIGSTKSZ [PR sim/28302]
	We map target signals to host signals so we can propagate signals
	between the host & simulated worlds.  That means we need to know
	the symbolic names & values of all signals that might be sent.

	The tools that generate that list use signal.h and include all
	symbols that start with "SIG" so as to automatically include any
	new symbols that the C library might add.  Unfortunately, this
	also picks up "SIGSTKSZ" which is not actually a signal itself,
	but a signal related setting -- it's the size of the stack when
	a signal is handled.

	By itself this doesn't super matter as we will never see a signal
	with that same value (since the range of valid signals tend to be
	way less than 1024, and the size of the default signal stack will
	never be that small).  But with recent glibc changes that make this
	into a dynamic value instead of a compile-time constant, some users
	see build failures when building the sim.

	As suggested by Adam Sampson, update our scripts to ignore this
	symbol to simplify everything and avoid the build failure.

	gdb: Support the c.mv insn in the riscv prologue scanner.
	While working on other problems, I encountered situations where GDB
	fails to properly unwind the stack because some functions use the C.MV
	instruction in the prologue.  The prologue scanner stops when it hits
	this instruction assuming its job is done at this point.  Unfortunately
	the prologue is not necessarily finished yet, preventing GDB to properly
	unwind.

	This commit adds support for handling such instruction in
	riscv_scan_prologue.

	Note that C.MV is part of the compressed instruction set.  The MV
	counterpart from the base ISA is a pseudo instruction that expands to
	'ADDI RD,RS1,0' which is already supported.

	Tested on riscv64-linux-gnu.

	gdb/testsuite/dwarf: don't define nested procs for rnglists/loclists
	When I wrote support for rnglists and loclists in the testsuite's DWARF
	assembler, I made it with nested procs, for example proc "table" inside
	proc "rnglists".  The intention was that this proc "table" could only be
	used by the user while inside proc "rnglists"'s body.  I had chosen very
	simple names, thinking there was no chance of name clashes.  I recently
	learned that this is not how TCL works.  This ends up defining a proc
	"table" in the current namespace ("Dwarf" in this case).

	Things still work if you generate rnglists and loclists in the same
	file, as each redefines its own procedures when executing.  But if a
	user of the assembler happened to define a convenience "table" or
	"start_end" procedure, for example, it would get overriden.

	I'd like to change how this works to reduce the chances of a name clash.

	 - Move the procs out of each other, so they are not defined in a nested
	   fashion.
	 - Prefix them with "_rnglists_" or "_loclists_".
	 - While calling $body in the various procs, temporarily make the procs
	   available under their "short" name.  For example, while in rngllists'
	   body, make _rnglists_table available as just "table".  This allows
	   existing code to keep working and keeps it not too verbose.
	 - Modify with_override to allow the overriden proc to not exist.  In
	   that case, the temporary proc is deleted on exit.

	Note the non-conforming indentation when calling with_override in
	_loclists_list.  This is on purpose: as we implement more loclists (and
	rnglists) entry types, the indentation would otherwise get larger and
	larger without much value for readability.  So I think it's reasonable
	here to put them on the same level.

	As follow-up to this discussion:

	  https://sourceware.org/pipermail/gdb-patches/2020-August/171385.html

	... make runto_main not pass no-message to runto.  This means that if we
	fail to run to main, for some reason, we'll emit a FAIL.  This is the
	behavior we want the majority of (if not all) the time.

	Without this, we rely on tests logging a failure if runto_main fails,
	otherwise.  They do so in a very inconsisteny mannet, sometimes using
	"fail", "unsupported" or "untested".  The messages also vary widly.
	This patch removes all these messages as well.

	Also, remove a few "fail" where we call runto (and not runto_main).  by
	default (without an explicit no-message argument), runto prints a
	failure already.  In two places, gdb.multi/multi-re-run.exp and
	gdb.python/py-pp-registration.exp, remove "message" passed to runto.
	This removes a few PASSes that we don't care about (but FAILs will still
	be printed if we fail to run to where we want to).  This aligns their
	behavior with the rest of the testsuite.

	Fix Windows crash from stop_pc change
	The "make thread_suspend_state::stop_pc optional" patch caused a
	regression on Windows when using shared libraries.  I tracked this
	down to an unguarded use of stop_pc() in the TARGET_WAITKIND_LOADED
	case of handle_inferior_event.  This patch fixes the bug by ensuring
	that the stop PC is set at this point.

	 (gdb) FAIL: gdb.multi/multi-term-settings.exp: inf1_how=attach: inf2_how=attach: stop with control-c (SIGINT)

	If you look at the testcase's sources, you'll see that the intention
	is to resumes the program with "continue", wait to see a few of those
	"pid=..., count=..." lines, and then interrupt the program with
	Ctrl-C.  But somehow, that resulted in GDB printing "Quit", instead of
	the Ctrl-C stopping the program with SIGINT.

	Here's what is happening:

	 #1 - those "pid=..., count=..." lines we see above weren't actually
	      output by the inferior after it has been continued (see #1).
	      Note that "inf1_how" and "inf2_how" are "attach".  What happened
	      is that those "pid=..., count=..." lines were output by the
	      inferiors _before_ they were attached to.  We see them at that
	      point instead of earlier, because that's where the testcase
	      reads from the inferiors' spawn_ids.

	 #2 - The testcase mistakenly thinks those "pid=..., count=..." lines
	      happened after the continue was processed by GDB, meaning it has
	      waited enough, and so sends the Ctrl-C.  GDB hasn't yet passed
	      the terminal to the inferior, so the Ctrl-C results in that
	      Quit.

	The fix here is twofold:

	 #1 - flush inferior output right after attaching

	 #2 - consume the "Continuing" printed by "continue", indicating the
	      inferior has the terminal.  This is the same as done throughout
	      the testsuite to handle this exact problem of sending Ctrl-C too
	      soon.

		* gdb.multi/multi-term-settings.exp (create_inferior): Flush

	[gdb/testsuite] Disable vgdb tests if xml not supported
	I build gdb without xml support using --without-expat, and ran into:
	...
	(gdb) target remote | vgdb --wait=2 --max-invoke-ms=2500 --pid=22032^M
	Remote debugging using | vgdb --wait=2 --max-invoke-ms=2500 --pid=22032^M
	relaying data between gdb and process 22032^M
	warning: Can not parse XML target description; XML support was disabled at \
	  compile time^M
	  ...
	(gdb) PASS: gdb.base/valgrind-infcall.exp: continue #1
	p gdb_test_infcall ()^M
	Remote 'g' packet reply is too long (expected 560 bytes, got 800 bytes): ...^M
	(gdb) FAIL: gdb.base/valgrind-infcall.exp: p gdb_test_infcall ()
	...

	After googling the error message with context valgrind gdbserver, I found
	indications that the Remote 'g' packet reply error is due to missing xml
	support.

	And here ( https://www.valgrind.org/docs/manual/manual-core-adv.html ) I
	found:
	...
	GDB version needed for ARM and PPC32/64.

	You must use a GDB version which is able to read XML target description sent
	by a gdbserver.  This is the standard setup if GDB was configured and built
	with the "expat" library.  If your GDB was not configured with XML support, it
	will report an error message when using the "target" command.  Debugging will
	not work because GDB will then not be able to fetch the registers from the
	Valgrind gdbserver.
	...

	So I guess I'm running into the same problem for x86_64.

	Fix this by skipping all gdb.base/valgrind-*.exp tests if xml support is not
	available.  Although only the gdb.base/valgrind-infcall*.exp produce fails,
	the Remote 'g' packet reply error occurs in all tests, so it seems prudent to
	disable them all.

	Tested on x86_64-linux.

	Error while executing Python code.^M
	(gdb) FAIL: gdb.python/py-breakpoint.exp: test_bkpt_auto_disable: \

	This is caused by the following:
	- a lambda function body needs to be an expression
	- in python 2, print is a statement, while in python 3 it's a function
	- a function call is an expression, and a statement is not.

	Fix this by defining a function print_bp_enabled:
	...
	def print_bp_enabled (bp):
	    print (bp.enabled)
	end
	...
	and using that instead.

	Tested on x86_64-linux.

	The problem is that the regexp expects "hit Breakpoint $decimal".  The "hit"

	The "hit" is printed by maybe_print_thread_hit_breakpoint, when
	show_thread_that_caused_stop returns true:
	...
	int
	show_thread_that_caused_stop (void)

	gdb: fix build when libbacktrace and execinfo backtrace are not available

	  Date:   Wed Aug 11 13:24:33 2021 +0100

	      gdb: use libbacktrace to create a better backtrace for fatal signals

	The build of GDB was broken iff, the execinfo backtrace API is not
	available, and, libbacktrace is either disabled, or not usable.  In
	this case you'll see build errors like this:

	      CXX    bt-utils.o

	         gdb_internal_backtrace_1 ();
	         ^~~~~~~~~~~~~~~~~~~~~~~~

	This commit fixes the issue by guarding the call to

	which is only defined when one of the backtrace libraries are
	available.

	gdb: enable target_async around stop_all_threads call in process_initial_stop_replies
	The following scenario hangs:

	 - maint set target-non-stop on
	 - `gdbserver --attach`
	 - a multi-threaded program

	For example:

	Terminal 1:

	    $ gnome-calculator&
	    [1] 495731
	    $ ../gdbserver/gdbserver --once --attach :1234 495731
	    Attached; pid = 495731
	    Listening on port 1234

	Terminal 2:

	    $ ./gdb -nx -q --data-directory=data-directory /usr/bin/gnome-calculator -ex "maint set target-non-stop on" -ex "tar rem :1234"
	    Reading symbols from /usr/bin/gnome-calculator...
	    (No debugging symbols found in /usr/bin/gnome-calculator)
	    Remote debugging using :1234
	    * hangs *

	What happens is:

	 - The protocol between gdb and gdbserver is in non-stop mode, but the
	   user-visible behavior is all-stop
	 - On connect, gdbserver sends one stop reply for one thread that is
	   stops, the others stay running
	 - In process_initial_stop_replies, gdb calls stop_all_threads to stop
	   these other threads, because we are using the all-stop user-visible
	   mode
	 - stop_all_threads sends a stop request for all the running threads and
	   then waits for resulting events
	 - At this point, the remote target is in target_async(0) mode, which
	   makes stop_all_threads not consider it for events
	 - stop_all_threads loops indefinitely (it does not even block
	   indefinitely, it is in an infinite busy loop) because there are no
	   event sources.  wait_one_event returns a TARGET_WAITKIND_NO_RESUMED
	   wait status.

	Fix that by making the remote target async around the stop_all_threads
	call.

	I haven't implemented it because I'm not sure how to do it, but I think
	it would be a good idea to have, in stop_all_threads / wait_one /
	handle_one, an assert to check that if we are expecting one or more
	event, then there are some targets that are in a state where they can
	supply some events.  Otherwise, we'll necessarily be stuck in this
	infinite loop, and it's probably due to a bug in GDB.  I'm not too sure
	where to put this or how to express it though.  Perhaps in
	stop_all_threads, here:

		  for (int i = 0; i < waits_needed; i++)
		    {
		      wait_one_event event = wait_one ();
		      *here*
		      if (handle_one (event))
			break;
		    }

	If at that point, the returned event is TARGET_WAITKIND_NO_RESUMED,
	there's a problem.  We expect some event, because we've asked some
	threads to stop, but all targets are answering that they won't have any
	events for us.  That's a contradiction, and a sign that something has
	gone wrong.  It could perhaps event be:

	    gdb_assert (event.ws.kind != TARGET_WAITKIND_NO_RESUMED);

	in handle_one, as the idea is the same in prepare_for_detach.

	A bit more sophisticated would be: we know which targets we are
	expecting waits from, since we know which threads we have asked to
	stop.  So if any of these targets returns TARGET_WAITKIND_NO_RESUMED,
	something is fishy.

	Add a test that tests attaching with gdbserver's --attach flag to a
	multi-threaded program, and then connecting to it.  Without the fix, the
	test reproduces the hang.

	Since add_location_to_breakpoint uses only the address as a criterion to

	order comes from the order of SALs when creating the breakpoint, which
	can vary from machine to machine.  While it would be more user-friendly
	to have a more stable order for printed breakpoint locations, it doesn't
	really matter for this test, and it would be hard to define an order
	that will be the same everywhere, all the time.

	So, loosen the regexp to accept "inf 1" and "inf 2" in any order.

	gdb: print backtrace for internal error/warning
	This commit builds on previous work to allow GDB to print a backtrace
	of itself when GDB encounters an internal-error or internal-warning.
	This fixes PR gdb/26377.

	There's not many places where we call internal_warning, and I guess in
	most cases the user would probably continue their debug session.  And
	so, in order to avoid cluttering up the output, by default, printing
	of a backtrace is off for internal-warnings.

	In contrast, printing of a backtrace is on by default for
	internal-errors, as I figure that in most cases hitting an
	internal-error is going to be the end of the debug session.

	Whether a backtrace is printed or not can be controlled with the new
	settings:

	  maintenance set internal-error backtrace on|off
	  maintenance show internal-error backtrace

	  maintenance set internal-warning backtrace on|off
	  maintenance show internal-warning backtrace

	Here is an example of what an internal-error now looks like with the
	backtrace included:

	  (gdb) maintenance internal-error blah
	  ../../src.dev-3/gdb/maint.c:82: internal-error: blah
	  A problem internal to GDB has been detected,
	  further debugging may prove unreliable.

	My hope is that this backtrace might make it slightly easier to
	diagnose GDB issues if all that is provided is the console output, I
	find that we frequently get reports of an assert being hit that is
	located in pretty generic code (frame.c, value.c, etc) and it is not
	always obvious how we might have arrived at the assert.

	gdb: use libbacktrace to create a better backtrace for fatal signals
	GDB recently gained the ability to print a backtrace when a fatal
	signal is encountered.  This backtrace is produced using the backtrace
	and backtrace_symbols_fd API available in glibc.

	However, in order for this API to actually map addresses to symbol
	names it is required that the application (GDB) be compiled with
	-rdynamic, which GDB is not by default.

	As a result, the backtrace produced often looks like this:

	  Fatal signal: Bus error
	  ----- Backtrace -----
	  ./gdb/gdb[0x80ec00]
	  ./gdb/gdb[0x80ed56]
	  /lib64/libc.so.6(+0x3c6b0)[0x7fc2ce1936b0]
	  /lib64/libc.so.6(__poll+0x4f)[0x7fc2ce24da5f]
	  ./gdb/gdb[0x15495ba]
	  ./gdb/gdb[0x15489b8]
	  ./gdb/gdb[0x9b794d]
	  ./gdb/gdb[0x9b7a6d]
	  ./gdb/gdb[0x9b943b]
	  ./gdb/gdb[0x9b94a1]
	  ./gdb/gdb[0x4175dd]
	  /lib64/libc.so.6(__libc_start_main+0xf3)[0x7fc2ce17e1a3]
	  ./gdb/gdb[0x4174de]
	  ---------------------

	This is OK if you have access to the exact same build of GDB, you can
	manually map the addresses back to symbols, however, it is next to
	useless if all you have is a backtrace copied into a bug report.

	GCC uses libbacktrace for printing a backtrace when it encounters an
	error.  In recent commits I added this library into the binutils-gdb
	repository, and in this commit I allow this library to be used by
	GDB.  Now (when GDB is compiled with debug information) the backtrace
	looks like this:

	  ----- Backtrace -----
	  0x80ee08 gdb_internal_backtrace
	  	../../src/gdb/event-top.c:989
	  0x80ef0b handle_fatal_signal
	  	../../src/gdb/event-top.c:1036
	  0x7f24539dd6af ???
	  0x7f2453a97a5f ???
	  0x154976f gdb_wait_for_event
	  	../../src/gdbsupport/event-loop.cc:613
	  0x1548b6d _Z16gdb_do_one_eventv
	  	../../src/gdbsupport/event-loop.cc:237
	  0x9b7b02 start_event_loop
	  	../../src/gdb/main.c:421
	  0x9b7c22 captured_command_loop
	  	../../src/gdb/main.c:481
	  0x9b95f0 captured_main
	  	../../src/gdb/main.c:1353
	  0x9b9656 _Z8gdb_mainP18captured_main_args
	  	../../src/gdb/main.c:1368
	  0x4175ec main
	  	../../src/gdb/gdb.c:32
	  ---------------------

	Which seems much more useful.

	Use of libbacktrace is optional.  If GDB is configured with
	--disable-libbacktrace then the libbacktrace directory will not be
	built, and GDB will not try to use this library.  In this case GDB
	would try to use the old backtrace and backtrace_symbols_fd API.

	All of the functions related to writing the backtrace of GDB itself
	have been moved into the new files gdb/by-utils.{c,h}.

	Copy in libbacktrace from gcc
	This copies in libbacktrace from the gcc repository as it was in the
	commit 62e420293a293608f383d9b9c7f2debd666e9fc9.  GDB is going to
	start using this library soon.

	A dependency between GDB and libbacktrace has already been added to
	the top level Makefile, so, after this commit, when building GDB,
	libbacktrace will be built first.  However, libbacktrace is not yet
	linked into GDB, or used by GDB in any way.

	It is possible to stop libbacktrace being built by configuring the
	tree with --disable-libbacktrace.

	This commit does NOT update src-release.sh, that will be done in the
	next commit, this commit ONLY imports libbacktrace from gcc.  This
	means that if you try to make a release of GDB from exactly this
	commit then the release tar file will not include libbacktrace.
	However, as libbacktrace is an optional dependency this is fine.

	top-level configure: setup target_configdirs based on repository
	The top-level configure script is shared between the gcc repository
	and the binutils-gdb repository.

	The target_configdirs variable in the configure.ac script, defines
	sub-directories that contain components that should be built for the
	target using the target tools.

	Some components, e.g. zlib, are built as both host and target
	libraries.

	This causes problems for binutils-gdb.  If we run 'make all' in the
	binutils-gdb repository we end up trying to build a target version of
	the zlib library, which requires the target compiler be available.
	Often the target compiler isn't immediately available, and so the
	build fails.

	The problem with zlib impacted a previous attempt to synchronise the
	top-level configure scripts from gcc to binutils-gdb, see this thread:

	  https://sourceware.org/pipermail/binutils/2019-May/107094.html

	And I'm in the process of importing libbacktrace in to binutils-gdb,
	which is also a host and target library, and triggers the same issues.

	I believe that for binutils-gdb, at least at the moment, there are no
	target libraries that we need to build.

	In the configure script we build three lists of things we want to
	build, $configdirs, $build_configdirs, and $target_configdirs, we also
	build two lists of things we don't want to build, $skipdirs and
	$noconfigdirs.  We then remove anything that is in the lists of things
	not to build, from the list of things that should be built.

	My proposal is to add everything in target_configdirs into skipdirs,
	if the source tree doesn't contain a gcc/ sub-directory.  The result
	is that for binutils-gdb no target tools or libraries will be built,
	while for the gcc repository, nothing should change.

	If a user builds a unified source tree, then the target tools and
	libraries should still be built as the gcc/ directory will be present.

	I've tested a build of gcc on x86-64, and the same set of target
	libraries still seem to get built.  On binutils-gdb this change
	resolves the issues with 'make all'.

	ChangeLog:

		* configure: Regenerate.
		* configure.ac (skipdirs): Add the contents of target_configdirs if
		we are not building gcc.

	sim: drop weak func attrs on module inits
	When I first wrote this, I was thinking we'd scan all source files
	that existed and generate a complete init list.  That means for any
	particular build, we'd probably have a few functions that didn't
	exist, so weak attributes was necessary.  What I ended up scanning
	though was only the source files that went into a particular build.

	There was another concern too: a source file might be included, but
	the build settings would cause all of its contents to be skipped
	(via CPP defines).  So scanning via naive grep would pick up names
	not actually available.  A check of the source tree shows that we
	never do this, and it's pretty easy to institute a policy that we
	don't start (by at the very least including a stub init func).

	The use of weak symbols ends up causing a problem in practice: for
	a few modules (like profiling), nothing else pulls it in, so the
	linker omits it entirely, which leads to the profiling module never
	being available.  So drop the weak markings since we know all these
	funcs will be available.

	 1. Using a test program that forks...
	 2. "set follow-fork-mode child"
	 3. "set detach-on-fork on" (the default)
	 4. run to a breakpoint somewhere after the fork

	Step 4 should have created a new inferior:

	    (gdb) info inferiors
	      Num  Description       Connection           Executable
	      1    <null>                                 /home/smarchi/build/wt/amd/gdb/fork
	    * 2    process 251425    1 (native)           /home/smarchi/build/wt/amd/gdb/fork

	By inspecting the state of GDB, we can see that the two inferiors now
	share one program space and one address space:

	Inferior 1:

	    (top-gdb) p inferior_list.m_front.num
	    $2 = 1
	    (top-gdb) p inferior_list.m_front.aspace
	    $3 = (struct address_space *) 0x5595e2520400
	    (top-gdb) p inferior_list.m_front.pspace
	    $4 = (struct program_space *) 0x5595e2520440

	Inferior 2:

	    (top-gdb) p inferior_list.m_front.next.num
	    $5 = 2
	    (top-gdb) p inferior_list.m_front.next.aspace
	    $6 = (struct address_space *) 0x5595e2520400
	    (top-gdb) p inferior_list.m_front.next.pspace
	    $7 = (struct program_space *) 0x5595e2520440

	You can then run inferior 1 again and the two inferiors will still
	erroneously share their spaces, but already at this point this is wrong.

	The cause of the bad {a,p}space sharing is in follow_fork_inferior.
	When following the child and detaching from the parent, we just re-use
	the parent's spaces, rather than cloning them.  When we switch back to
	inferior 1 and run again, we find ourselves with two unrelated inferiors
	sharing spaces.

	Fix that by creating new spaces for the parent after having moved them
	to the child.  My initial implementation created new spaces for the
	child instead.  Doing this breaks doing "next" over fork().  When "next"
	start, we record the symtab of the starting location.  When the program
	stops, we compare that symtab with the symtab the program has stopped
	at.  If the symtab or the line number has changed, we conclude the
	"next" is done.  If we create a new program space for the child and copy
	the parent's program space to it with clone_program_space, it creates
	new symtabs for the child as well.  When the child stop, but still on
	the fork() line, GDB thinks the "next" is done because the symtab
	pointers no longer match.  In reality they are two symtab instances that
	represent the same file.  But moving the spaces to the child and
	creating new spaces for the parent, we avoid this problem.

	Note that the problem described above happens today with "detach-on-fork
	off" and "follow-fork-mode child", because we create new spaces for the
	child.  This will have to be addressed later.

	Test-wise, improve gdb.base/foll-fork.exp to set a breakpoint that is
	expected to have a location in each inferiors.  Without the fix, when
	the two inferiors erroneously share a program space, GDB reports a
	single location.

	libctf, lookup: fix bounds of pptrtab lookup
	An off-by-one bug in the check for pptrtab lookup meant that we could
	access the pptrtab past its bounds (*well* past its bounds),
	particularly if we called ctf_lookup_by_name in a child dict with "*foo"
	where "foo" is a type that exists in the parent but not the child and no
	previous lookups by name have been carried out.  (Note that "*foo" is
	not even a valid thing to call ctf_lookup_by_name with: foo * is.
	Nonetheless, users sometimes do call ctf_lookup_by_name with invalid
	content, and it should return ECTF_NOTYPE, not crash.)

	ctf_pptrtab_len, as its name suggests (and as other tests of it in
	ctf-lookup.c confirm), is one higher than the maximum valid permissible
	index, so the comparison is wrong.

	(Test added, which should fail pretty reliably in the presence of this
	bug on any machine with 4KiB pages.)

	libctf: fix handling of CTF symtypetab sections emitted by older GCC
	Older (pre-upstreaming) GCC emits a function symtypetab section of a
	format never read by any extant libctf.  We can detect such CTF dicts by
	the lack of the CTF_F_NEWFUNCINFO flag in their header, and we do so
	when reading in the symtypetab section -- but if the set of symbols with
	types is sufficiently sparse, even an older GCC will emit a function
	index section.

	In NEWFUNCINFO-capable compilers, this section will always be the exact
	same length as the corresponding function section (each is an array of
	uint32_t, associated 1:1 with each other). But this is not true for the
	older compiler, for which the sections are different lengths.  We check
	to see if the function symtypetab section and its index are the same
	length, but we fail to skip this check when this is not a NEWFUNCINFO
	dict, and emit a spurious corruption error for a CTF dict we could
	have perfectly well opened and used.

	Fix trivial: check the flag (and fix the terrible grammar of the error
	message at the same time).

	libctf: try several possibilities for linker versioning flags
	Checking for linker versioning by just grepping ld --help output for
	mentions of --version-script is inadequate now that Solaris 11.4
	implements a --version-script with different semantics.  Try linking a
	test program with a small wildcard-using version script with each
	supported set of flags in turn, to make sure that linker versioning is
	not only advertised but actually works.

	The Solaris "GNU-compatible" linker versioning is not quite
	GNU-compatible enough, but we can work around the differences by
	generating a new version script that removes the comments from the
	original (Solaris ld requires #-style comments), and making another
	version script for libctf-nonbfd in particular which doesn't mention any
	of the symbols that appear in libctf.la, to avoid Solaris ld introducing
	corresponding new NOTYPE symbols to match the version script.

	libtool.m4: fix nm BSD flag detection
	Libtool needs to get BSD-format (or MS-format) output out of the system
	nm, so that it can scan generated object files for symbol names for
	-export-symbols-regex support.  Some nms need specific flags to turn on
	BSD-formatted output, so libtool checks for this in its AC_PATH_NM.
	Unfortunately the code to do this has a pair of interlocking flaws:

	 - it runs the test by doing an nm of /dev/null.  Some platforms
	   reasonably refuse to do an nm on a device file, but before now this
	   has only been worked around by assuming that the error message has a
	   specific textual form emitted by Tru64 nm, and that getting this
	   error means this is Tru64 nm and that nm -B would work to produce
	   BSD-format output, even though the test never actually got anything
	   but an error message out of nm -B.  This is fixable by nm'ing *nm
	   itself* (since we necessarily have a path to it).

	 - the test is entirely skipped if NM is set in the environment, on the
	   grounds that the user has overridden the test: but the user cannot
	   reasonably be expected to know that libtool wants not only nm but
	   also flags forcing BSD-format output.  Worse yet, one such "user" is
	   the top-level Cygnus configure script, which neither tests for
	   nor specifies any BSD-format flags.  So platforms needing BSD-format
	   flags always fail to set them when run in a Cygnus tree, breaking
	   -export-symbols-regex on such platforms.  Libtool also needs to
	   augment $LD on some platforms, but this is done unconditionally,
	   augmenting whatever the user specified: the nm check should do the
	   same.

	   One wrinkle: if the user has overridden $NM, a path might have been
	   provided: so we use the user-specified path if there was one, and
	   otherwise do the path search as usual.  (If the nm specified doesn't
	   work, this might lead to a few extra pointless path searches -- but
	   the test is going to fail anyway, so that's not a problem.)

	(Tested with NM unset, and set to nm, /usr/bin/nm, my-nm where my-nm is a
	symlink to /usr/bin/nm on the PATH, and /not-on-the-path/my-nm where
	*that* is a symlink to /usr/bin/nm.)

	libctf: link against libiberty before linking in libbfd or libctf-nobfd
	This ensures that the CTF_LIBADD, which always contains at least this
	when doing a shared link:

	-L`pwd`/../libiberty/pic -liberty

	appears in the link line before any requirements pulled in by libbfd.la,
	which include -liberty but because it is install-time do not include the
	-L`pwd`/../libiberty/pic portion (in an indirect dep like this, the path
	comes from the libbfd.la file, and is an install path).  libiberty also
	appears after libbfd in the link line by virtue of libctf-nobfd.la,
	because libctf-nobfd has to follow libbfd in the link line, and that
	needs symbols from libiberty too.

	Without this, an installed liberty might well be pulled in by libbfd,
	and if --enable-install-libiberty is not specified this libiberty might
	be completely incompatible with what is being installed and break either
	or boht of libbfd and libctf. (The specific problem observed here is
	that bsearch_r was not present, but other problems might easily be
	observed in future too.)

	Because ld links against libctf, this has a tendency to break the system
	linker at install time too, if installing with --prefix=/usr.  That's
	quite unpleasant to recover from.

	gdb: add setting to disable reading source code files
	In some situations it is possible that a user might not want GDB to

	It is almost certainly possible that using some combination of 'set

	being unable to find the source files, but this feels like a rather
	crude way to solve the problem.

	In this commit a new option is add that stops GDB from opening and

	gdb: prevent an assertion when computing the frame_id for an inline frame
	I ran into this assertion while GDB was trying to unwind the stack:

	  gdb/inline-frame.c:173: internal-error: void inline_frame_this_id(frame_info*, void**, frame_id*): Assertion `frame_id_p (*this_id)' failed.

	That is, when building the frame_id for an inline frame, GDB asks for
	the frame_id of the previous frame.  Unfortunately, no valid frame_id
	was returned for the previous frame, and so the assertion triggers.

	What is happening is this, I had a stack that looked something like
	this (the arrows '->' point from caller to callee):

	  normal_frame -> inline_frame

	However, for whatever reason (e.g. broken debug information, or
	corrupted stack contents in the inferior), when GDB tries to unwind
	"normal_frame", it ends up getting back effectively the same frame,
	thus the call stack looks like this to GDB:

	  .-> normal_frame -> inline_frame
	  |     |
	  '-----'

	Given such a situation we would expect GDB to terminate the stack with
	an error like this:

	  Backtrace stopped: previous frame identical to this frame (corrupt stack?)

	However, the inline_frame causes a problem, and here's why:

	When unwinding we start from the sentinel frame and call
	get_prev_frame.  We eventually end up in get_prev_frame_if_no_cycle,
	in here we create a raw frame, and as this is frame #0 we immediately
	return.

	However, eventually we will try to unwind the stack further.  When we
	do this we inevitably needing to know the frame_id for frame #0, and
	so, eventually, we end up in compute_frame_id.

	In compute_frame_id we first find the right unwinder for this frame,
	in our case (i.e. for inline_frame) the $pc is within the function
	normal_frame, but also within a block associated with the inlined
	function inline_frame, as such the inline frame unwinder claims this
	frame.

	Back in compute_frame_id we next compute the frame_id, for our
	inline_frame this means a call to inline_frame_this_id.

	The ID of an inline frame is based on the id of the previous frame, so
	from inline_frame_this_id we call get_prev_frame_always, this
	eventually calls get_prev_frame_if_no_cycle again, which creates
	another raw frame and calls compute_frame_id (for frames other than
	frame 0 we immediately compute the frame_id).

	In compute_frame_id we again identify the correct unwinder for this
	frame.  Our $pc is unchanged, however, the fact that the next frame is
	of type INLINE_FRAME prevents the inline frame unwinder from claiming
	this frame again, and so, the standard DWARF frame unwinder claims
	normal_frame.

	We return to compute_frame_id and call the standard DWARF function to
	build the frame_id for normal_frame.

	With the frame_id of normal_frame figured out we return to
	compute_frame_id, and then to get_prev_frame_if_no_cycle, where we add
	the ID for normal_frame into the frame_id cache, and return the frame
	back to inline_frame_this_id.

	From inline_frame_this_id we build a frame_id for inline_frame and
	return to compute_frame_id, and then to get_prev_frame_if_no_cycle,
	which adds the frame_id for inline_frame into the frame_id cache.

	So far, so good.

	However, as we are trying to unwind the complete stack, we eventually
	ask for the previous frame of normal_frame, remember, at this point
	GDB doesn't know the stack is corrupted (with a cycle), GDB still
	needs to figure that out.

	So, we eventually end up in get_prev_frame_if_no_cycle where we create
	a raw frame and call compute_frame_id, remember, this is for the frame
	before normal_frame.

	The first task for compute_frame_id is to find the unwinder for this
	frame, so all of the frame sniffers are tried in order, this includes
	the inline frame sniffer.

	The inline frame sniffer asks for the $pc, this request is sent up the
	stack to normal_frame, which, due to its cyclic behaviour, tells GDB
	that the $pc in the previous frame was the same as the $pc in
	normal_frame.

	GDB spots that this $pc corresponds to both the function normal_frame
	and also the inline function inline_frame.  As the next frame is not
	an INLINE_FRAME then GDB figures that we have not yet built a frame to
	cover inline_frame, and so the inline sniffer claims this new frame.
	Our stack is now looking like this:

	  inline_frame -> normal_frame -> inline_frame

	But, we have not yet computed the frame id for the outer most (on the
	left) inline_frame.  After the frame sniffer has claimed the inline
	frame GDB returns to compute_frame_id and calls inline_frame_this_id.

	In here GDB calls get_prev_frame_always, which eventually ends up
	in get_prev_frame_if_no_cycle again, where we create a raw frame and
	call compute_frame_id.

	Just like before, compute_frame_id tries to find an unwinder for this
	new frame, it sees that the $pc is within both normal_frame and
	inline_frame, but the next frame is, again, an INLINE_FRAME, so, just
	like before the standard DWARF unwinder claims this frame.  Back in
	compute_frame_id we again call the standard DWARF function to build
	the frame_id for this new copy of normal_frame.

	At this point the stack looks like this:

	  normal_frame -> inline_frame -> normal_frame -> inline_frame

	After compute_frame_id we return to get_prev_frame_if_no_cycle, where
	we try to add the frame_id for the new normal_frame into the frame_id
	cache, however, unlike before, we fail to add this frame_id as it is
	a duplicate of the previous normal_frame frame_id.  Having found a
	duplicate get_prev_frame_if_no_cycle unlinks the new frame from the
	stack, and returns nullptr, the stack now looks like this:

	  inline_frame -> normal_frame -> inline_frame

	The nullptr result from get_prev_frame_if_no_cycle is fed back to
	inline_frame_this_id, which forwards this to get_frame_id, which
	immediately returns null_frame_id.  As null_frame_id is not considered
	a valid frame_id, this is what triggers the assertion.

	In summary then:

	 - inline_frame_this_id currently assumes that as the inline frame
	   exists, we will always get a valid frame back from
	   get_prev_frame_always,

	 - get_prev_frame_if_no_cycle currently assumes that it is safe to
	   return nullptr when it sees a cycle.

	Notice that in frame.c:compute_frame_id, this code:

	  fi->this_id.value = outer_frame_id;
	  fi->unwind->this_id (fi, &fi->prologue_cache, &fi->this_id.value);
	  gdb_assert (frame_id_p (fi->this_id.value));

	The assertion makes it clear that the this_id function must always
	return a valid frame_id (e.g. null_frame_id is not a valid return
	value), and similarly in inline_frame.c:inline_frame_this_id this
	code:

	  *this_id = get_frame_id (get_prev_frame_always (this_frame));
	  /* snip comment */
	  gdb_assert (frame_id_p (*this_id));

	Makes it clear that every inline frame expects to be able to get a
	previous frame, which will have a valid frame_id.

	As I have discussed above, these assumptions don't currently hold in
	all cases.

	One possibility would be to move the call to get_prev_frame_always
	forward from inline_frame_this_id to inline_frame_sniffer, however,
	this falls foul of (in frame.c:frame_cleanup_after_sniffer) this
	assertion:

	  /* No sniffer should extend the frame chain; sniff based on what is
	     already certain.  */
	  gdb_assert (!frame->prev_p);

	This assert prohibits any sniffer from trying to get the previous
	frame, as getting the previous frame is likely to depend on the next
	frame, I can understand why this assertion is a good thing, and I'm in
	no rush to alter this rule.

	The solution proposed here takes onboard feedback from both Pedro, and
	Simon (see the links below).  The get_prev_frame_if_no_cycle function
	is renamed to get_prev_frame_maybe_check_cycle, and will now not do
	cycle detection for inline frames, even when we spot a duplicate frame
	it is still returned.  This is fine, as, if the normal frame has a
	duplicate frame-id then the inline frame will also have a duplicate
	frame-id.  And so, when we reject the inline frame, the duplicate
	normal frame, which is previous to the inline frame, will also be
	rejected.

	In inline-frame.c the call to get_prev_frame_always is no longer
	nested inside the call to get_frame_id.  There are reasons why
	get_prev_frame_always can return nullptr, for example, if there is a
	memory error while trying to get the previous frame, if this should
	happen then we now give a more informative error message.

	The test-case gdb.threads/process-dies-while-detaching.exp takes about 20s

	Move value_true to value.h
	I noticed that value_true is declared in language.h and defined in

	better in one of those files.  And, because it is very short, I
	changed it to be an inline function in value.h.  I've also removed a
	comment from the implementation, on the basis that it seems obsolete
	-- if the change it suggests was needed, it probably would have been
	done by now; and if it is needed in the future, odds are it would be
	done differently anyway.

	Finally, this patch also changes value_true and value_logical_not to

	Fix handling of DW_AT_data_bit_offset
	A newer version of GCC will now emit member locations using just
	DW_AT_data_bit_offset, like:

	 <3><14fe>: Abbrev Number: 1 (DW_TAG_member)
	    <14ff>   DW_AT_name        : (indirect string, offset: 0x215e): nb_bytes
	    <1503>   DW_AT_decl_file   : 1
	    <1503>   DW_AT_decl_line   : 10
	    <1504>   DW_AT_decl_column : 7
	    <1505>   DW_AT_type        : <0x150b>
	    <1509>   DW_AT_bit_size    : 31
	    <150a>   DW_AT_data_bit_offset: 64

	whereas earlier versions would emit something like:

	 <3><164f>: Abbrev Number: 7 (DW_TAG_member)
	    <1650>   DW_AT_name        : (indirect string, offset: 0x218d): nb_bytes

	    <165d>   DW_AT_bit_offset  : 1
	    <165e>   DW_AT_data_member_location: 8

	That is, DW_AT_data_member_location is not emitted any more.  This is
	a change due to the switch to DWARF 5 by default.

	This change pointed out an existing bug in gdb, namely that the
	attr_to_dynamic_prop depends on the presence of
	DW_AT_data_member_location.  This patch moves the handling of
	DW_AT_data_bit_offset into handle_data_member_location, and updates
	attr_to_dynamic_prop to handle this new case.

	A new test case is included.  This test fails with GCC 11, but passes
	with an earlier version of GCC.

	[gdb/testsuite] Don't leave gdb instance running after function_range
	A typical dwarf assembly test-case start like this:
	...
	standard_testfile .c -debug.S

	set asm_file [standard_output_file $srcfile2]
	Dwarf::assemble $asm_file {
	  ...
	}

	if { [prepare_for_testing "failed to prepare" ${testfile} \
		  [list $srcfile $asm_file] {nodebug}] } {
	    return -1
	}
	...

	When accidentally using build_for_executable instead of
	prepare_for_testing (or intentionally using it but forgetting to add
	clean_restart $binfile or some such) the mistake may not be caught, because
	another gdb instance is still running, and we may silently end up testing
	compiler-generated DWARF.

	This can be caused by something relatively obvious, like an earlier
	prepare_for_testing or clean_restart, but also by something more obscure like
	function_range, which may even be triggered by dwarf assembly like this:
	...
	  {MACRO_AT_func {main}}
	...

	Fix this by calling gdb_exit at the end of function_range.

	Also fix the fallout of that in test-case gdb.dwarf2/dw2-bad-elf.exp, where a
	get_sizeof call used the gdb instance left lingering by function_range.

	[ A better and more complete fix would add a new proc get_exec_info, that would
	be called at the start of the dwarf assembly body:
	...
	Dwarf::assemble $asm_file {
	  get_exec_info {main foo} {int void*}
	...
	that would:
	- do a prepare_for_testing with $srcfile (roughtly equivalent to what
	  MACRO_AT_func does,
	- call function_range for all functions main and foo, without starting a
	  new gdb instance
	- set corresponding variables at the call-site: main_start, main_len,
	  main_end, foo_start, foo_len, foo_end.
	- get size for types int and void*
	- set corresponding variables at the call-site: int_size, void_ptr_size.
	- do a gdb_exit. ]

	[gdb/testsuite] Use pie instead of -fpie/-pie
	I noticed two test-cases where -fpie is used.  Using the canonical pie option
	will usually get one -fPIE instead.

	That choice is justified here in gdb_compile:
	...
	  # For safety, use fPIE rather than fpie. On AArch64, m68k, PowerPC
	  # and SPARC, fpie can cause compile errors due to the GOT exceeding
	  # a maximum size.  On other architectures the two flags are
	  # identical (see the GCC manual). Note Debian9 and Ubuntu16.10
	  # onwards default GCC to using fPIE.  If you do require fpie, then
	  # it can be set using the pie_flag.
	  set flag "additional_flags=-fPIE"
	...

	There is no indication that using -fpie rather than -fPIE is on purpose, so
	use pie instead.

	When running test-case gdb.dwarf2/implptr-64bit.exp with target board

	[gdb/testsuite] Fix set $var val in gdb.dwarf2/dw2-is-stmt.exp
	When doing a testrun with:
	...
	$ make check RUNTESTFLAGS=$(cd $src/gdb/testsuite/; echo gdb.dwarf2/*.exp)
	...
	I ran into:
	...
	ERROR: tcl error sourcing gdb.dwarf2/dw2-is-stmt.exp.
	ERROR: expected integer but got "dw2-abs-hi-pc-world.c"
	    while executing
	"incr i"
	...

	The variable i is set in gdb.dwarf2/dw2-abs-hi-pc.exp, and leaks to
	gdb.dwarf2/dw2-is-stmt.exp.  It's not removed by gdb_cleanup_globals because i
	is set as global variable by runtest.exp, which does:
	...
	for { set i 0 } { $i < $argc } { incr i } {
	...
	at toplevel but forgets to unset the variable.

	Fix this by removing '$' in front of the variable name when doing set:
	...
	-set $i 0
	+set i 0
	...

	Tested on x86_64-linux.

	[gdb/testsuite] Use pie/nopie instead of ldflags=-pie/-no-pie
	I noticed two test-case that use ldflags=-pie and ldflags-no-pie, instead of
	the canonical pie and nopie options, which would typically also add
	additional_flags=-fPIE respectively additional_flags=-fno-pie.

	There is no indication that this is on purpose, so replace these with pie and
	nopie.

	Tested on x86_64-linux.

	[gdb/testsuite] Add gdb.testsuite/dump-system-info.exp
	When interpreting the testsuite results, it's often relevant what kind of
	machine the testsuite ran on.  On a local machine one can just do
	/proc/cpuinfo, but in case of running tests using a remote system
	that distributes test runs to other remote systems that are not directly
	accessible, that's not possible.

	Fix this by dumping /proc/cpuinfo into the gdb.log, as well as lsb_release -a
	and uname -a.

	We could do this at the start of each test run, by putting it into unix.exp
	or some such.  However, this might be too verbose, so we choose to put it into
	its own test-case, such that it get triggered in a full testrun, but not when
	running one or a subset of tests.

	We put the test-case into the gdb.testsuite directory, which is currently the
	only place in the testsuite where we do not test gdb.   [ Though perhaps this
	could be put into a new gdb.info directory, since the test-case doesn't
	actually test the testsuite. ]

	Tested on x86_64-linux.

	Change pointer_type to a method of struct type
	I noticed that pointer_type is declared in language.h and defined in
	language.c.  However, it really has to do with types, so it should
	have been in gdbtypes.h all along.

	This patch changes it to be a method on struct type.  And, I went
	through uses of TYPE_IS_REFERENCE and updated many spots to use the
	new method as well.  (I didn't update ones that were in arch-specific
	code, as I couldn't readily test that.)

	[gdb/testsuite] Support -fPIE/-fno-PIE/-pie/-no-pie in gdb_compile_rust
	When running gdb.rust/*.exp test-cases with target board unix/-fPIE/-pie, I
	run into:
	...
	builtin_spawn -ignore SIGHUP rustc --color never gdb.rust/watch.rs \
	  -g -lm -fPIE -pie -o outputs/gdb.rust/watch/watch^M
	error: Unrecognized option: 'f'^M
	^M
	compiler exited with status 1
	...

	The problem is that -fPIE and -fpie are gcc options, but for rust we use
	rustc, which has different compilation options.

	Fix this by translating the gcc options to rustc options in gdb_compile_rust,
	similar to how that is done for ada in target_compile_ada_from_dir.

	Likewise for unix/-fno-PIE/-no-pie.

	Tested on x86_64-linux, with:
	- native
	- unix/-fPIE/-pie
	- unix/-fno-PIE/-no-pie
	specifically, on openSUSE Leap 15.2 both with package gcc-PIE:
	- installed (making gcc default to PIE)
	- uninstalled (making gcc default to non-PIE).
	and rustc 1.52.1.

	Test that frame info/IDs are stable/consistent
	This adds a testcase that tests that the unwinder produces consistent
	frame info and frame IDs by making sure that "info frame" shows the
	same result when stopped at a function (level == 0), compared to when
	we find the same frame in the stack at a level > 0.

	E.g., on x86-64, right after running to main, we see:

	  (gdb) info frame
	  Stack level 0, frame at 0x7fffffffd340:
	   rip = 0x555555555168 in main (gdb.base/backtrace.c:41); saved rip = 0x7ffff7dd90b3
	   source language c.
	   Arglist at 0x7fffffffd330, args:
	   Locals at 0x7fffffffd330, Previous frame's sp is 0x7fffffffd340
	   Saved registers:
	    rbp at 0x7fffffffd330, rip at 0x7fffffffd338
	  (gdb)

	and then after continuing to a function called by main, and selecting
	the "main" frame again, we see:

	  (gdb) info frame
	  Stack level 3, frame at 0x7fffffffd340:
	   rip = 0x555555555172 in main (gdb.base/backtrace.c:41); saved rip = 0x7ffff7dd90b3
	   caller of frame at 0x7fffffffd330
	   source language c.
	   Arglist at 0x7fffffffd330, args:
	   Locals at 0x7fffffffd330, Previous frame's sp is 0x7fffffffd340
	   Saved registers:
	    rbp at 0x7fffffffd330, rip at 0x7fffffffd338
	  (gdb)

	The only differences should be in the stack level, the 'rip = '
	address, and the presence of the "caller of frame at" info.  All the
	rest should be the same.  If it isn't, it probably means that the
	frame base, the frame ID, etc. aren't stable & consistent.

	The testcase exercises both the DWARF and the heuristic unwinders,
	using "maint set dwarf unwinder on/off".

	Tested on {x86-64 -m64, x86-64 -m32, Aarch64, Power8} GNU/Linux.

	Change get_ada_task_ptid parameter type
	get_ada_task_ptid currently takes a 'long' as its 'thread' parameter
	type.  However, on some platforms this is actually a pointer, and
	using 'long' can sometimes end up with the value being sign-extended.
	This sign extension can cause problems later, if the tid is then later
	used as an address again.

	This patch changes the parameter type to ULONGEST and updates all the
	uses.  This approach preserves sign extension on the targets where it
	is apparently intended, while avoiding it on others.

	Change ptid_t::tid to ULONGEST
	The ptid_t 'tid' member is normally used as an address in gdb -- both
	bsd-uthread and ravenscar-thread use it this way.  However, because

	This patch changes the type to ULONGEST to ensure that sign extension
	does not occur.

	I wanted to find, and potentially modify, all the spots where the

	removed this parameter and then rebuilt.

	In order to make it simpler to search through the "real" (nonzero)
	uses of this parameter, something I knew I'd have to do multiple
	times, I removed any ", 0" from constructor calls.

	dwarf2 sub-section test
	This is a testcase for the bug fixed by commit 5b4846283c3d.  When
	running the testcase on ia64 targets I found timeouts along with lots
	of memory being consumed, due to ia64 gas not tracking text
	sub-sections.  Trying to add nops for ".nop 16" in ".text 1" resulting
	in them being added to subsegment 0, with no increase to subsegment 1
	size.  This patch also fixes that problem.

	Note that the testcase fails on ft32-elf, mn10200-elf, score-elf,

	[gdb/testsuite] Handle supports_memtag in gdb.base/gdb-caching-proc.exp
	In test-case gdb.base/gdb-caching-proc.exp, we run all procs declared with
	gdb_caching_proc.  Some of these require a gdb instance, some not.

	We could just do a clean_restart every time, but that would amount to 44 gdb
	restarts.  We try to minimize this by doing this only for the few procs that
	need it, and hardcoding those in the test-case.

	For those procs, we do a clean_restart, execute the proc, and then do a
	gdb_exit, to make sure the gdb instance doesn't linger such that we detect
	procs that need a gdb instance but are not listed in the test-case.

	However, that doesn't work in the case of gnat_runtime_has_debug_info.  This
	proc doesn't require a gdb instance because it starts its own.  But it doesn't
	clean up the gdb instance, and since it's not listed, the test-case
	doesn't clean up the gdb instance eiter.  Consequently, the proc
	supports_memtag (which should be listed, but isn't) uses the gdb instance
	started by gnat_runtime_has_debug_info rather than throwing an error.  Well,
	unless gnat_runtime_has_debug_info fails before starting a gdb instance, in
	which case we do run into the error.

	Fix this by:
	- doing gdb_exit unconditionally
	- fixing the resulting error by adding supports_memtag in the test-case to
	  the "needing gdb instance" list

	Tested on x86_64-linux.

	gdbsupport/gdb_proc_service.h: use decltype instead of typeof
	Bug 28341 shows that GDB fails to compile when built with -std=c++11.
	I don't know much about the use case, but according to the author of the
	bug:

	    I encountered the scenario where CXX is set to "g++ -std=c++11" when
	    I try to compile binutils under GCC as part of the GCC 3-stage
	    compilation, which is common for building a cross-compiler.

	The author of the bug suggests using __typeof__ instead of typeof.  But
	since we're using C++, we might as well use decltype, which is standard.
	This is what this patch does.

	The failure (and fix) can be observed by configuring GDB with CXX="g++
	-std=c++11":

	riscv: print .2byte or .4byte before an unknown instruction encoding
	When the RISC-V disassembler encounters an unknown instruction, it
	currently just prints the value of the bytes, like this:

	  Dump of assembler code for function custom_insn:
	     0x00010132 <+0>:	addi	sp,sp,-16
	     0x00010134 <+2>:	sw	s0,12(sp)
	     0x00010136 <+4>:	addi	s0,sp,16
	     0x00010138 <+6>:	0x52018b
	     0x0001013c <+10>:	0x9c45

	My proposal, in this patch, is to change the behaviour to this:

	  Dump of assembler code for function custom_insn:
	     0x00010132 <+0>:	addi	sp,sp,-16
	     0x00010134 <+2>:	sw	s0,12(sp)
	     0x00010136 <+4>:	addi	s0,sp,16
	     0x00010138 <+6>:	.4byte	0x52018b
	     0x0001013c <+10>:	.2byte	0x9c45

	Adding the .4byte and .2byte opcodes.  The benefit that I see here is
	that in the patched version of the tools, the disassembler output can
	be fed back into the assembler and it should assemble to the same
	binary format.  Before the patch, the disassembler output is invalid
	assembly.

	I've started a RISC-V specific test file under binutils so that I can
	add a test for this change.

	CTF: multi-CU and archive support
	Now gdb is capable of debugging executable, which consists of multiple
	compilation units (CUs) with the CTF debug info. An executable could
	potentially have one or more archives, which, in CTF context, contain
	conflicting types.

	all changes were made in ctfread.c in which elfctf_build_psymtabs was
	modified to handle archives, via the ctf archive iterator and its callback
	build_ctf_archive_member and scan_partial_symbols was modified to scan
	archives, which are treated as subfiles, to build the psymtabs.

	Also changes were made to handle CTF's data object section and function
	info section which now share the same format of their contents - an array
	of type IDs. New functions ctf_psymtab_add_stt_entries, which is called by
	ctf_psymtab_add_stt_obj and ctf_psymtab_add_stt_func, and add_stt_entries,
	which is called by add_stt_obj and add_stt_func when setting up psymtabs
	and full symtab, respectively.

	The test-case expects the backtrace command to trigger remote communication,
	which then should result in a "Remote connection closed" or similar.

	However, no remote communication is triggered, because we hit the "Check that
	this frame is unwindable" case in get_prev_frame_always_1.

	We don't hit this problem in the kill_pid_of=inferior case, because there we

	[gdb/ada] Handle artificial local symbols
	With current master and gcc 7.5.0/8.5.0, we have this timeout:
	...
	(gdb) print s^M
	Multiple matches for s^M
	[0] cancel^M
	[1] s at src/gdb/testsuite/gdb.ada/interface/foo.adb:20^M
	[2] s at src/gdb/testsuite/gdb.ada/interface/foo.adb:?^M
	> FAIL: gdb.ada/interface.exp: print s (timeout)
	...

	[ The FAIL doesn't reproduce with gcc 9.3.1.  This difference in
	behaviour bisects to gcc commit d70ba0c10de.

	The FAIL with earlier gcc bisects to gdb commit ba8694b650b. ]

	The FAIL is caused by gcc generating this debug info describing a named
	artificial variable:
	...
	 <2><1204>: Abbrev Number: 31 (DW_TAG_variable)
	    <1205>   DW_AT_name        : s.14
	    <1209>   DW_AT_type        : <0x1213>
	    <120d>   DW_AT_artificial  : 1
	    <120d>   DW_AT_location    : 5 byte block: 91 e0 7d 23 18   \
	      (DW_OP_fbreg: -288; DW_OP_plus_uconst: 24)
	...

	An easy way to fix this would be to simply not put named artificial variables
	into the symbol table.  However, that causes regressions for Ada.  It relies
	on being able to get the value from such variables, using a named reference.

	Fix this instead by marking the symbol as artificial, and:
	- ignoring such symbols in ada_resolve_variable, which fixes the FAIL
	- ignoring such ada symbols in do_print_variable_and_value, which prevents
	  them from showing up in "info locals"

	Note that a fix for the latter was submitted here (
	https://sourceware.org/pipermail/gdb-patches/2008-January/054994.html ), and
	this patch borrows from it.

	Tested on x86_64-linux.

	PR28149 part 2, purge generated line info
	Mixing compiler generated line info with gas generated line info is
	generally just confusing.  Also .loc directives with non-zero view
	fields might reference a previous .loc.  It becomes a little more
	tricky to locate that previous .loc if there might be gas generated
	line info present too.  Mind you, we turn off gas generation of line
	info on seeing compiler generated line info, so any reference back

	PR28149, debug info with wrong file association
	gcc-11 and gcc-12 pass -gdwarf-5 to gas, in order to prime gas for
	DWARF 5 level debug info.  Unfortunately it seems there are cases
	where the compiler does not emit a .file or .loc dwarf debug directive
	before any machine instructions.  (Note that the .file directive
	typically emitted as the first line of assembly output doesn't count as
	a dwarf debug directive.  The dwarf .file has a file number before the
	file name string.)

	This patch delays allocation of file numbers for gas generated line
	debug info until the end of assembly, thus avoiding any clashes with
	compiler generated file numbers.  Two fixes for test case source are
	necessary;  A .loc can't use a file number that hasn't already been
	specified with .file.

	A followup patch will remove all the gas generated line info on
	seeing a .file directive.

	[GOLD] Remove addend from Local_got_entry_key
	This patch removes the addend from Local_got_entry_key, which is

	might be advantageous to keep the addend in Local_got_entry_key when

	relocations.  I opted to save some memory by removing the field but

	RISC-V: Merged extension string tables and their version tables into one.
	There are two main reasons for this patch,

	* In the past we had two extension tables, one is used to record all
	supported extensions in bfd/elfxx-riscv.c, another is used to get the
	default extension versions in gas/config/tc-riscv.c.  It is hard to
	maintain lots of tables in different files, but in fact we can merge
	them into just one table.  Therefore, we now define many riscv_supported_std*
	tables, which record names and versions for all supported extensions.
	We not only use these tables to initialize the riscv_ext_order, but
	also use them to get the default versions of extensions, and decide if
	the extensions should be enbaled by default.

	* We add a new filed `default_enable' for the riscv_supported_std* tables,
	to decide if the extension should be enabled by default.  For now if the
	`default_enable' field of the extension is set to EXT_DEFAULT, then we
	should enable the extension when the -march and elf architecture attributes
	are not set.  In the future, I suppose the `default_enable' can be set
	to lots of EXT_<VENDOR>, each vendor can decide to open which extensions,
	when the target triple of vendor is chosen.

	The elf/linux regression tests of riscv-gnu-toolchain are passed.

	The problem is that the sleep (300) call at the end of main is interrupted,
	which causes the inferior to exit before the ctrl-c can be send.

	This problem is described at "Interrupted System Calls" in the docs, and the
	suggested solution (using a sleep loop) indeed fixes the problem.

	Fix this instead using the more prevalent:
	...
	  alarm (300);
	  ...
	  while (1) sleep (1);
	...
	which is roughly equivalent because the sleep is called at the end of main,
	but slightly better because it guards against hangs from the start rather than
	from the end of main.

	Likewise in gdb.base/watch_thread_num.exp.

	Likewise in gdb.btrace/enable-running.exp, but use the sleep loop there,
	because the sleep is not called at the end of main.

	[gdb/testsuite] Use function_range in gdb.dwarf2/dw2-abs-hi-pc.exp
	When I run test-case gdb.dwarf2/dw2-abs-hi-pc.exp with gcc, we have:
	...
	(gdb) break hello^M
	Breakpoint 1 at 0x4004c0: file dw2-abs-hi-pc-hello.c, line 24.^M

	(gdb) break hello^M
	Breakpoint 1 at 0x4004e4^M
	(gdb) FAIL: gdb.dwarf2/dw2-abs-hi-pc.exp: break hello
	...

	The problem is that the CU and function both have an empty address range:
	...
	 <0><d2>: Abbrev Number: 1 (DW_TAG_compile_unit)
	    <108>   DW_AT_name        : dw2-abs-hi-pc-hello.c

	    <13e>   DW_AT_high_pc     : 0x4004e0
	...

	The address ranges are set like this in dw2-abs-hi-pc-hello-dbg.S:
	...
	        .4byte  .hello_start    /* DW_AT_low_pc */
	        .4byte  .hello_end      /* DW_AT_high_pc */
	...
	where the labels refer to dw2-abs-hi-pc-hello.c:
	...
	extern int v;

	asm (".hello_start: .globl .hello_start\n");
	void
	hello (void)
	{
	asm (".hello0: .globl .hello0\n");
	  v++;
	asm (".hello1: .globl .hello1\n");
	}
	asm (".hello_end: .globl .hello_end\n");
	...

	Using asm labels in global scope is a known source of problems, as explained
	in the comment of proc function_range in gdb/testsuite/lib/dwarf.exp.

	Fix this by using function_range instead.

	This happens as follows.

	The function foo:

	 <1><31>: Abbrev Number: 4 (DW_TAG_subprogram)
	    <33>   DW_AT_name        : foo
	    <37>   DW_AT_ranges      : 0x0

	has these ranges:

	    00000000 00000000004004ae 00000000004004af
	    00000000 <End of list>
	...
	which have a hole at at [0x4004af,0x4004c1).

	However, the address map of the partial symtabs incorrectly maps addresses
	in the hole (such as 0x4004b6 in the backtrace) to the foo CU.

	The address map of the full symbol table of the foo CU however does not
	contain the addresses in the hole, which is what the warning / internal error
	complains about.

	Fix this by making sure that ranges of functions are read correctly.

	The patch adds a bit to struct partial_die_info, in this hole (shown for
	x86_64-linux):
	...
	/*   11: 7   |     4 */    unsigned int canonical_name : 1;
	/* XXX  4-byte hole  */
	/*   16      |     8 */    const char *raw_name;
	...
	So there's no increase in size for 64-bit, but AFAIU there will be an increase
	for 32-bit.

	  Compilation Unit @ offset 0x150:
	  Compilation Unit @ offset 0x308:
	...
	of which the ones at 0xc7 and 0x145 are dummy CUs (that is, they do not
	contain a single DIE), which were added by recent commit 5ef670d81fd
	"[gdb/testsuite] Add dummy start and end CUs in dwarf assembly".

	The .debug_names section contains this CU table:
	...
	[  0] 0x0
	[  1] 0x2e
	[  2] 0xa5
	[  3] 0xd2
	[  4] 0x150
	[  5] 0x308
	[  6] 0x1
	[  7] 0x0
	...
	The last two entries are incorrect, and the entries for the dummy CUs are
	missing.

	The last two entries are incorrect because here in write_debug_names we write
	the dimension of the CU list as 8:
	...
	  /* comp_unit_count - The number of CUs in the CU list.  */
	  header.append_uint (4, dwarf5_byte_order,
	                     per_objfile->per_bfd->all_comp_units.size ()
	                     - per_objfile->per_bfd->tu_stats.nr_tus);
	...
	while the actual dimension of the CU list is 6.

	The discrepancy is caused by this code which skips the dummy CUs:
	...
	  for (int i = 0; i < per_objfile->per_bfd->all_comp_units.size (); ++i)
	    {
	      ...
	      /* CU of a shared file from 'dwz -m' may be unused by this main
	        file.  It may be referenced from a local scope but in such
	        case it does not need to be present in .debug_names.  */
	      if (psymtab == NULL)
	       continue;
	...
	because they have a null partial symtab.

	We can fix this by writing the actual dimension of the CU list, but that still
	leaves the dummy CUs out of the CU list.  The purpose of having these is to
	delimit the end of preceding CUs.

	So, fix this by:
	- removing the code that skips the dummy CUs (note that the same change
	  was done for .gdb_index in commit efba5c2319d '[gdb/symtab] Handle PU
	  without import in "save gdb-index"'.
	- verifying that all units are represented in the CU/TU lists
	- using the actual CU list size when writing the dimension of the CU list
	  (and likewise for the TU list).

	bytes and produce (using verbose = true in disasm-selftests.c):
	...
	arm mov r0, #0
	...
	but instead the disassembler uses thumb mode and only consumes 2
	bytes and produces:
	...
	arm movs        r0, r0
	...

	The failure does not show up in the "no executable loaded" variant because
	this code in gdb_print_insn_arm isn't triggered:
	...
	  if (current_program_space->exec_bfd () != NULL)
	    info->flags |= USER_SPECIFIED_MACHINE_TYPE;
	...
	and consequently we do this in print_insn:
	...
	      if ((info->flags & USER_SPECIFIED_MACHINE_TYPE) == 0)
	        info->mach = bfd_mach_arm_unknown;
	...
	and don't set force_thumb to true in select_arm_features.

	The code in gdb_print_insn_arm makes the assumption that the disassembly
	architecture matches the exec architecture, which in this case is incorrect,
	because the exec architecture is x86_64, and the disassembly architecture is
	armv8.1-m.main.  Fix that by explicitly checking it:
	...
	  if (current_program_space->exec_bfd () != NULL
	      && (current_program_space->exec_bfd ()->arch_info
		  == gdbarch_bfd_arch_info (gdbarch)))
	...

	This fixes the print_one_insn failure, so remove the KFAIL.

	Tested on x86_64-linux.

	[gdb/tdep] Reset force_thumb in parse_arm_disassembler_options
	With a gdb build with --enable-targets=all, we have 2 arch-specific failures
	in selftest print_one_insn:
	...
	$ gdb -q -batch a.out -ex "maint selftest print_one_insn" 2>&1 \
	  | grep "Self test failed: arch "
	Self test failed: arch armv8.1-m.main: self-test failed at \
	  disasm-selftests.c:165
	Self test failed: arch arm_any: self-test failed at disasm-selftests.c:165
	$
	...

	During the first failed test, force_thumb is set to true, and remains so until
	and during the second test, which causes the second failure.

	Fix this by resetting force_thumb to false in parse_arm_disassembler_options,
	such that we get just one failure:
	...
	$ gdb -q -batch a.out -ex "maint selftest print_one_insn" 2>&1 \
	  | grep "Self test failed: arch "
	Self test failed: arch armv8.1-m.main: self-test failed at \

	Fix no-Python build
	A build without Python will currently fail, because
	selftests::test_python uses gdb_python_initialized, which is only
	conditionally defined.

	This patch fixes the build by making test_python also be conditionally
	defined.  I chose this approach because the selftest will fail if
	Python is not enabled, so it didn't seem useful to leave it defined.

	[gdb/testsuite] Fix gdb.gdb/selftest.exp
	With a gdb build with CFLAGS "-O2 -g -flto=auto", I run into:

	The problem is that gdb_main has been inlined into main, and consequently the

	[gdb/testsuite] Set sysroot earlier in local-board.exp
	When running test-case gdb.base/batch-exit-status.exp for native, it passes.
	But with target board cc-with-debug-names, we run into (added missing double
	quotes for clarity):
	...
	builtin_spawn $build/gdb/testsuite/../../gdb/gdb -nw -nx \
	  -data-directory $build/gdb/testsuite/../data-directory \
	  -iex "set height 0" -iex "set width 0" -ex "set sysroot" -batch ""^M

	PASS: gdb.base/batch-exit-status.exp: \

	FAIL: gdb.base/batch-exit-status.exp: \
	  : No such file or directory\.: [lindex $result 3] == $expect_status
	...

	The difference between the passing and failing case is that with native we
	have (leaving out set height/width for brevity):
	...
	$ gdb -batch ""; echo $?
	: No such file or directory.
	1
	...
	and with target board cc-with-debug-names:
	...
	$ gdb -ex "set sysroot" -batch ""; echo $?
	: No such file or directory.
	0
	...

	The difference is expected.  GDB returns the exit status of the last executed
	command.  In the former case that's 'file ""', which fails.  In the latter case,
	that's 'set sysroot', which succeeds.

	Fix this by setting sysroot using -iex instead of -ex in local-board.exp, such
	that we have the expected:
	...
	$ gdb -iex "set sysroot" -batch ""; echo $?
	: No such file or directory.

	[gdb/testsuite] Fix handling of nr_args < 3 in mi_gdb_test

	arguments are mandatory:
	...
	 # mi_gdb_test COMMAND PATTERN MESSAGE [IPATTERN] -- send a command to gdb;
	 #   test the result.
	...

	However, this is not checked, and when mi_gdb_test is called with less than 3

	...
	set re [list "~" {"} {[$]} $decimal " = 1" "\\\\" "n" {"} "\r\n" "\\^" "done"]

	            [string_to_regexp " = 1\\n\"\r\n^done"]]
	set re [join $re ""]
	...
	Note: we have to avoid applying string_to_list to decimal, which is already a
	regexp.

	gdb/python: remove all uses of Py_TPFLAGS_HAVE_ITER
	Python 2 has a bit flag Py_TPFLAGS_HAVE_ITER which can be passed as
	part of the tp_flags field when defining a new object type.  This flag
	is not defined in Python 3 and so we define it to 0 in
	python-internal.h (when IS_PY3K is defined).

	The meaning of this flag is that the object has the fields tp_iter and
	tp_iternext.  Note the use of "has" here, the flag says nothing about
	the values in those fields, just that the type object has the fields.

	In early versions of Python 2 these fields were no part of the
	PyTypeObject struct, they were added in version 2.2 (see
	https://docs.python.org/release/2.3/api/type-structs.html).  And so,
	there could be a some code compiled out there which has a PyTypeObject
	structure within it that doesn't even have the tp_iter and tp_iternext
	fields, attempting to access these fields would be undefined
	behaviour.

	And so Python added the Py_TPFLAGS_HAVE_ITER flag.  If the flag is
	present then Python is free to access the tp_iter and tp_iternext
	fields.

	If we consider GDB then we always assume that the tp_iter and
	tp_iternext fields are part of PyTypeObject.  If someone was crazy
	enough to try and compile GDB against Python 2.1 then we'd get lots of
	build errors saying that we were passing too many fields when
	initializing PyTypeObject structures.  And so, I claim, we can be sure
	that GDB will always be compiled with a version of Python that has the
	tp_iter and tp_iternext fields in PyTypeObject.

	Next we can look at the Py_TPFLAGS_DEFAULT flag.  In Python 2, each
	time additional fields are added to PyTypeObject a new Py_TPFLAGS_*
	flag would be defined to indicate whether those flags are present or
	not.  And, those new flags would be added to Py_TPFLAGS_DEFAULT.  And
	so, in the latest version of Python 2 the Py_TPFLAGS_DEFAULT flag
	includes Py_TPFLAGS_HAVE_ITER (see
	https://docs.python.org/2.7/c-api/typeobj.html).

	In GDB we pass Py_TPFLAGS_DEFAULT as part of the tp_flags for all
	objects we define.

	And so, in this commit, I propose to remove all uses of
	Py_TPFLAGS_HAVE_ITER from GDB, it's simply not needed.

	There should be no user visible changes after this commit.

	sim: accept -EB/-EL short options
	Many GNU tools accept -EB/-EL as short options for selecting big &

	it all to simplify the code (and to get us a little closer to the

	sim: mips: delete unused PSIZE define
	It's unclear what this define is for as it appears to be unused, and

	most sim files don't include many system headers, but enabling sockser
	code for mingw uncovers the conflict.

	Unfortunately the error produced by gcc is inscrutable, but running

	sim: ppc: switch to common warning flags
	Now that the ppc code has been cleaned up enough to use the same set
	of warning flags as the common code, delete the ppc-specific configure
	logic so we can leverage what the common code already defined for us.

2021-09-09  Tom de Vries  <tdevries@suse.de>

	sim: ppc: enable -Wpointer-sign warnings
	When compiling with --enable-werror and CFLAGS="-O0 -g -Wall", we run into:
	...
	src/sim/ppc/hw_memory.c: In function 'hw_memory_init_address':
	src/sim/ppc/hw_memory.c:204:7: error: pointer targets in passing argument 4 \
	  of 'device_find_integer_array_property' differ in signedness \
	  [-Werror=pointer-sign]
	       &new_chunk->size);
	       ^
	...

	Fix these by adding an explicit pointer cast.  It's a bit ugly to use APIs
	based on signed integers to read out unsigned values, but in practice, this
	is par for the course in the ppc code.

	We already use signed APIs and assign the result to unsigned values a lot:
	see how device_find_integer_property returns a signed integer (cell), but
	then assign it to unsigned types.  The array APIs are not used that often
	which is why we don't see many warnings, and we disable warnings when we
	assign signed integers to unsigned integers in general.

	The dtc/libfdt project (which is the standard in other projects) processes
	the fdt blob as a series of bytes without any type information.  Typing is
	left to the caller.  They have core APIs that read/write bytes, and a few
	helper functions to cast/convert those bytes to the right value (e.g. u32).
	In this ppc sim code, the core APIs use signed integers, and the callers
	convert to unsigned, usually implicitly.

	We could add some core APIs to the ppc sim that deal with raw bytes and then
	add some helpers to convert to the right type, but that seems like a lot of
	lifting for what boils down to a cast, and is effectively equivalent to all
	the implicit assignments we use elsewhere.  Long term, a lot of the ppc code
	should either get converted to existing sim common code, or we should stand
	up proper APIs in the common code first, or use standard libraries to do all
	the processing (e.g. libfdt).  Either way, this device.c code would all get
	deleted, and callers (like these hw_*.c files) would get converted.  Which
	is also why we go with a cast rather new (but largely unused) APIs.

2021-09-09  Mike Frysinger  <vapier@gentoo.org>

	sim: ppc: enable -Wmissing-declarations & -Wmissing-prototypes
	This aligns with common code which already uses this flag.  We have
	to add another local prototype to fix the failure, and add another
	local decl for the SIM_DESC type.  Unwinding these will require a
	lot more work & conversions in the process, so going with the decl
	for now unblocks the warning unification.

	gdb: make thread_suspend_state::stop_pc optional
	Currently the stop_pc field of thread_suspect_state is a CORE_ADDR and
	when we want to indicate that there is no stop_pc available we set
	this field back to a special value.

	There are actually two special values used, in post_create_inferior
	the stop_pc is set to 0.  This is a little unfortunate, there are
	plenty of embedded targets where 0 is a valid pc value.  The more
	common special value for stop_pc though, is set in
	thread_info::set_executing, where the value (~(CORE_ADDR) 0) is used.

	This commit changes things so that the stop_pc is instead a
	gdb::optional.  We can now explicitly reset the field to an
	uninitialised state, we also have asserts that we don't read the
	stop_pc when its in an uninitialised state (both in
	gdbsupport/gdb_optional.h, when compiling with _GLIBCXX_DEBUG
	defined, and in thread_info::stop_pc).

	One situation where a thread will not have a stop_pc value is when the
	thread is stopped as a consequence of GDB being in all stop mode, and
	some other thread stopped at an interesting event.  When GDB brings
	all the other threads to a stop those other threads will not have a
	stop_pc set (thus avoiding an unnecessary read of the pc register).

	Previously, when GDB passed through handle_one (in infrun.c) the
	threads executing flag was set to false and the stop_pc field was left
	unchanged, i.e. it would (previous) have been left as ~0.

	Now, handle_one leaves the stop_pc with no value.

	This caused a problem when we later try to set these threads running
	again, in proceed() we compare the current pc with the cached stop_pc.
	If the thread was stopped via handle_one then the stop_pc would have
	been left as ~0, and the compare (in proceed) would (likely) fail.
	Now however, this compare tries to read the stop_pc when it has no
	value and this would trigger an assert.

	To resolve this I've added thread_info::stop_pc_p() which returns true
	if the thread has a cached stop_pc.  We should only ever call
	thread_info::stop_pc() if we know that there is a cached stop_pc,
	however, this doesn't mean that every call to thread_info::stop_pc()
	needs to be guarded with a call to thread_info::stop_pc_p(), in most
	cases we know that the thread we are looking at stopped due to some
	interesting event in that thread, and so, we know that the stop_pc is
	valid.

	After running the testsuite I've seen no other situations where
	stop_pc is read uninitialised.

	There should be no user visible changes after this commit.

	[gdb/testsuite] Handle eof in gdb_internal_error_resync

	[gdb/testsuite] Check avx support in gdb.arch/amd64-disp-step-avx.exp
	On a machine on Open Build Service I'm running into a SIGILL for test-case
	gdb.arch/amd64-disp-step-avx.exp:
	...
	Program received signal SIGILL, Illegal instruction.^M
	test_rip_vex2 () at gdb.arch/amd64-disp-step-avx.S:40^M
	40              vmovsd ro_var(%rip),%xmm0^M
	(gdb) FAIL: gdb.arch/amd64-disp-step-avx.exp: vex2: \
	  continue to test_rip_vex2_end
	...
	The SIGILL happens when trying to execute the first avx instruction in the
	executable.

	I can't directly access the machine, but looking at the log for test-case
	gdb.arch/i386-avx.exp, it seems that there's no avx support:
	...
	Breakpoint 1, main (argc=1, argv=0x7fffffffd6b8) at gdb.arch/i386-avx.c:68^M
	68        if (have_avx ())^M
	(gdb) print have_avx ()^M
	$1 = 0^M
	...

	Fix this by:
	- adding a gdb_caching_proc have_avx, similar to have_mpx, using the have_avx
	  function from gdb.arch/i386-avx.c
	- using proc have_avx in both gdb/testsuite/gdb.arch/amd64-disp-step-avx.exp
	  and gdb/testsuite/gdb.arch/i386-avx.exp.

	Tested on my x86_64-linux laptop with avx support, where both test-cases pass.

	Use CORE_ADDR as return type from x86_dr_low_get_addr
	On a Windows build locally, watchpoints started failing.  I tracked
	this down to x86_dr_low_get_addr returning an 'unsigned long'... in
	this particular build, this is a 32-bit type, but the inferior is a
	64-bit program.

	This patch fixes the problem by changing the return type.  No other
	change is required, because this matches the function pointer in
	struct x86_dr_low_type.

	Test case reproducing PR28030 bug
	The original reproducer for PR28030 required use of a specific
	compiler version - gcc-c++-11.1.1-3.fc34 is mentioned in the PR,
	though it seems probable that other gcc versions might also be able to
	reproduce the bug as well.  This commit introduces a test case which,
	using the DWARF assembler, provides a reproducer which is independent
	of the compiler version.  (Well, it'll work with whatever compilers
	the DWARF assembler works with.)

	To the best of my knowledge, it's also the first test case which uses
	the DWARF assembler to provide debug info for a shared object.  That
	being the case, I provided more than the usual commentary which should
	allow this case to be used as a template when a combo shared
	library / DWARF assembler test case is required in the future.

	I provide some details regarding the bug in a comment near the
	beginning of locexpr-dml.exp.

	This problem was difficult to reproduce; I found myself constantly
	referring to the backtrace while trying to figure out what (else) I
	might be missing while trying to create a reproducer.  Below is a
	partial backtrace which I include for posterity.

	I'll note a few points regarding this backtrace:

	Frame #1 is where the internal error occurs.  It's caused by an
	unhandled case for FIELD_LOC_KIND_DWARF_BLOCK.  The fix for this bug
	adds support for this case.

	Frame #22 - it's a partial backtrace - shows that GDB is attempting to
	(re)run the program.  You can see the exact command sequence that was
	used for reproducing this problem in the PR (at
	https://sourceware.org/bugzilla/show_bug.cgi?id=28030), but in a
	nutshell, after starting the program and advancing to the appropriate
	source line, GDB was asked to step into libstdc++; a "finish" command
	was issued, returning a value.  The fact that a value was returned is
	very important.  GDB was then used to step back into libstdc++.  A
	breakpoint was set on a source line in the library after which a "run"
	command was issued.

	Frame #19 shows a call to objfile_purge_solibs.  It's aptly named.

	Frame #7 is a call to the destructor for one of the objfile solibs; it
	turned out to be the one for libstdc++.

	Frames #6 thru #3 show various value preservation frames.  If you look
	at preserve_values() in gdb/value.c, the value history is preserved
	first, followed by internal variables, followed by values for the
	extension languages (python and guile).

	using CC for the target compiler, and CC_FOR_HOST for the host
	compiler, with the makefiles passing CC=$CC_FOR_TARGET and
	CC_FOR_HOST=$CC to the runtest invocation.

	One exception to the rule of using CC_FOR_TARGET is the native-only ld
	bootstrap test, which uses the newly built ld to link a copy of
	itself.  Since the files being linked were created with the host
	compiler, the boostrap test should use CC and CFLAGS, in case some
	host compiler option provides needed libraries automatically.
	However, bootstrap.exp used CC where it should have used CC_FOR_HOST.
	I set about fixing that problem, then decided that playing games in
	the makefiles with CC was a bad idea.  Not only is it confusing, but
	other dejagnu code knows about CC_FOR_TARGET.  See dejagnu/target.exp.

	So this patch gets rid of the makefile variable renaming and changes
	all the .exp files to use the correct _FOR_TARGET variables.
	CC_FOR_HOST and CFLAGS_FOR_HOST disappear.  A followup patch will
	correct bootstrap.exp to use CFLAGS, and a number of other things I
	noticed.

	SHT_SYMTAB_SHNDX handling
	.symtab_shndx section contents is an array, one entry for each symbol

	keep both dest_index and destshndx_index in elf_sym_strtab.  Instead,

	NULL when .symtab_shndx does not exist.  Also, strtabcount in the

	[gdb/testsuite] Fix dwo path in fission-*.S
	[ Using $build for /home/vries/gdb_versions/devel/build to make things a bit
	more readable. ]

	When using make check// to run test-case gdb.dwarf2/fission-base.exp:
	...
	( cd $build/gdb; make check//unix RUNTESTFLAGS="fission-base.exp" )
	...
	we run into:
	...
	(gdb) file \
	  $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base^M
	Reading symbols from \
	  $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base...^M
	warning: Could not find DWO CU \
	  $build/gdb/testsuite.1/outputs/gdb.dwarf2/fission-base/fission-base.dwo \
	  (0x807060504030201) referenced by CU at offset 0xc7 [in module \
	  $build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base]^M
	...

	The problem is that the executable refers to the dwo file using path name
	$build/gdb/testsuite.1/outputs/gdb.dwarf2/fission-base/fission-base.dwo,
	while the actual dwo file is at
	$build/gdb/testsuite.unix/outputs/gdb.dwarf2/fission-base/fission-base.dwo.

	This is caused by this trick in fission-base.S:
	...
	 #define XSTR(s) STR(s)
	 #define STR(s) #s
	   ...
	   .asciz XSTR(DWO)        # DW_AT_GNU_dwo_name
	...
	and:
	...
	$ echo | gcc -E -dD - | grep "define unix"
	...

	I used this trick to avoid doing additional_flags=-DDWO=\"$dwo\", since I was
	concerned that there could be quoting issues.

	However, I've found other uses of this pattern, f.i. in
	gdb/testsuite/gdb.base/corefile-buildid.exp:
	...
	  additional_flags=-DSHLIB_NAME=\"$dlopen_lib\"]
	...

	So, fix this by:
	- using additional_flags=-DDWO=\"$dwo\" and
	- using plain DWO instead of XSTR(DWO)

	Likewise in other gdb.dwarf2/fission*.exp test-cases.

	Tested on x86_64-linux, using make check//unix.

	RISC-V: Extend .insn directive to support hardcode encoding.
	The .insn directive can let users use their own instructions, or
	some new instruction, which haven't supported in the old binutils.
	For example, if users want to use sifive cache instruction, they
	cannot just write "cflush.d1.l1" in the assembly code, they should
	use ".insn i SYSTEM, 0, x0, x10, -0x40".  But the .insn directive
	may not easy to use for some cases, and not so friendly to users.
	Therefore, I believe most of the users will use ".word 0xfc050073",
	to encode the instructions directly, rather than use .insn.  But
	once we have supported the mapping symbols, the .word directives
	are marked as data, so disassembler won't dump them as instructions
	as usual.  I have discussed this with Kito many times, we all think
	extend the .insn direcitve to support the hardcode encoding, is the
	easiest way to resolve the problem.  Therefore, there are two more
	.insn formats are proposed as follows,

	(original) .insn <type>, <operand1>, <operand2>, ...
	           .insn <insn-length>, <value>
	           .insn <value>

	Use gdbfmt for vprintf_filtered.
	gdbfmt was already used for printf_filtered, so using it for
	vprintf_filtered is more consistent.

	As a result, all callers of vfprintf_maybe_filtered now use gdbfmt, so
	the function can be simplified to assume the gdbfmt case and remove
	the associated bool argument.  Similary, vprintf_filtered is now a

	fbsd-nat: Don't use '%jd' and '%ju' with printf_filtered.
	The handler for 'info proc status' for native processes on FreeBSD
	uses the 'j' size modifier along with uintmax_t / intmax_t casts to
	output integer values for types such as off_t that are not aliases of
	a basic C type such as 'int' or 'long'.  printf_filtered does not
	support the 'j' modifer, so this resulted in runtime errors in
	practice:

	RISC-V: PR27916, Support mapping symbols.
	Similar to ARM/AARCH64, we add mapping symbols in the symbol table,
	to mark the start addresses of data and instructions.  The $d means
	data, and the $x means instruction.  Then the disassembler uses these
	symbols to decide whether we should dump data or instruction.

	Consider the mapping-04 test case,
	$ cat tmp.s
	  .text
	  .option norelax
	  .option norvc
	  .fill 2, 4, 0x1001
	  .byte 1
	  .word 0
	  .balign 8
	  add a0, a0, a0
	  .fill 5, 2, 0x2002
	  add a1, a1, a1
	  .data
	  .word 0x1             # No need to add mapping symbols.
	  .word 0x2

	$ riscv64-unknown-elf-as tmp.s -o tmp.o
	$ riscv64-unknown-elf-objdump -d tmp.o

	Disassembly of section .text:

	0000000000000000 <.text>:
	   0:   00001001         .word   0x00001001  # Marked $d, .fill directive.
	   4:   00001001         .word   0x00001001
	   8:   00000001         .word   0x00000001  # .byte + part of .word.
	   c:   00               .byte   0x00        # remaining .word.
	   d:   00               .byte   0x00        # Marked $d, odd byte of alignment.
	   e:   0001             nop                 # Marked $x, nops for alignment.
	  10:   00a50533         add     a0,a0,a0

	  22:   0001             nop                 # Section tail alignment.
	  24:   00000013         nop

	* Use $d and $x to mark the distribution of data and instructions.
	  Alignments of code are recognized as instructions, since we usually
	  fill nops for them.

	* If the alignment have odd bytes, then we cannot just fill the nops
	  into the spaces.  We always fill an odd byte 0x00 at the start of
	  the spaces.  Therefore, add a $d mapping symbol for the odd byte,
	  to tell disassembler that it isn't an instruction.  The behavior
	  is same as Arm and Aarch64.

	The elf/linux toolchain regressions all passed.  Besides, I also
	disable the mapping symbols internally, but use the new objudmp, the
	regressions passed, too.  Therefore, the new objudmp should dump
	the objects corretly, even if they don't have any mapping symbols.

	[gdb/testsuite] Improve argument syntax of proc arange
	The current syntax of proc arange is:
	...
	  proc arange { arange_start arange_length {comment ""} {seg_sel ""} } {
	...
	and a typical call looks like:
	...
	  arange $start $len
	...

	This style is somewhat annoying because if you want to specify the last
	parameter, you need to give the default values of all the other optional ones
	before as well:
	...
	  arange $start $len "" $seg_sel
	...

	Update the syntax to:
	...
	    proc arange { options arange_start arange_length } {
	       parse_options {
	           { comment "" }
	           { seg_sel "" }
	       }
	...
	such that a typical call looks like:
	...
	  arange {} $start $len
	...
	and a call using seg_sel looks like:
	...
	  arange {
	    seg_sel $seg_sel
	  } $start $len
	...

	Also update proc aranges, which already has an options argument, to use the
	new proc parse_options.

	[gdb/symtab] Don't write .gdb_index symbol table with empty entries
	When comparing the sizes of the index files generated for shlib
	outputs/gdb.dwarf2/dw2-zero-range/shr1.sl, I noticed a large difference
	between .debug_names:
	...
	$ gdb -q -batch $shlib -ex "save gdb-index -dwarf-5 ."
	$ du -b -h shr1.sl.debug_names shr1.sl.debug_str

	$ du -b -h shr1.sl.gdb-index

	The problem is that the .gdb_index contains a non-empty symbol table with only

	[gdb/testsuite] Generate .debug_aranges in gdb.dlang/watch-loc.exp
	Before commit 5ef670d81fd "[gdb/testsuite] Add dummy start and end CUs in
	dwarf assembly" we had in exec outputs/gdb.dlang/watch-loc/watch-loc a D
	compilation unit at offset 0xc7:
	...

	 <0><d2>: Abbrev Number: 2 (DW_TAG_compile_unit)
	    <d3>   DW_AT_language    : 19       (D)
	...
	with a corresponding .debug_aranges entry:
	...
	Offset into .debug_info:  0xc7
	  Pointer Size:             4
	  Segment Size:             0

	    004004a7 0000000b
	    00000000 00000000
	...

	After that commit we have a dummy CU at offset 0xc7 and the D compilation unit
	at offset 0xd2:
	...
	  Compilation Unit @ offset 0xc7:
	   Length:        0x7 (32-bit)
	   Version:       4

	 <0><dd>: Abbrev Number: 2 (DW_TAG_compile_unit)
	    <de>   DW_AT_language    : 19       (D)
	...
	while the .debug_aranges entry still points to 0xc7.

	The problem is that the test-case uses a hack (quoting from
	commit 75f06e9dc59):
	...
	[ Note: this is a non-trivial test-case.  The file watch-loc-dw.S contains a
	.debug_info section, but not an .debug_aranges section or any actual code.
	The file watch-loc.c contains code and a .debug_aranges section, but no other
	debug section.  So, the intent for the .debug_aranges section in watch-loc.c
	is to refer to a compilation unit in the .debug_info section in
	watch-loc-dw.S. ]
	...
	and adding the dummy CU caused that hack to stop working.

	Fix this by moving the generation of .debug_aranges from watch-loc.c to
	watch-loc.exp, such that we have:
	...
	  Offset into .debug_info:  0xd2
	  Pointer Size:             4

	[gdb/testsuite] Add label option to proc cu
	We can use current dwarf assembly infrastructure to declare a label that marks

	  declare_labels header_start_cu_a
	  _section ".debug_info"
	  header_start_cu_a : cu {} {
	  }
	  _section ".debug_info"
	  header_start_cu_b : cu {} {
	  }
	...
	on the condition that we switch to the .debug_info section before, which makes
	this style of use fragile.

	Another way to achieve the same is to use the label as generated by the cu
	proc itself:
	...
	  variable _cu_label
	  cu {} {
	  }
	  set header_start_cu_a $_cu_label
	  cu {} {
	  }
	  set header_start_cu_b $_cu_label
	...
	but again that seems fragile given that adding a new CU inbetween will
	silently result in the wrong value for the label.

	Add a label option to proc cu such that we can simply do:
	...
	  cu { label header_start_cu_a } {
	  }
	  cu { label header_start_cu_b } {
	  }
	...

	Fix two regressions caused by CU / TU merging
	PR symtab/28160 and PR symtab/27893 concern GDB crashes in the test
	suite when using the "fission" target board.  They are both caused by
	the patches that merge the list of CUs with the list of TUs (and to a
	lesser degree by the patches to share DWARF data across objfiles), and
	the underlying issue is the same: it turns out that reading a DWO can
	cause new type units to be created.  This means that the list of
	dwarf2_per_cu_data objects depends on precisely which CUs have been
	expanded.  However, because the type units can be created while
	expanding a CU means that the vector of CUs can expand while it is
	being iterated over -- a classic mistake.  Also, because a TU can be
	added later, it means the resize_symtabs approach is incorrect.

	This patch fixes resize_symtabs by removing it, and having set_symtab
	resize the vector on demand.  It fixes the iteration problem by
	introducing a safe (index-based) iterator and changing the relevant
	spots to use it.

	Fix a latent bug in dw2-ranges-overlap.exp
	dw2-ranges-overlap.exp creates a program where a psymtab has two
	address ranges, and a function without debug info whose address is
	between these two ranges.  Then it sets a breakpoint on this function
	and runs to it, expecting that the language should remain "auto; c"
	when stopped.

	However, this test case also has a "main" function described (briefly)
	in the DWARF, and this function is given language C++.  Also, a
	breakpoint stop sets the current language to the language that was
	used when setting the breakpoint.

	My new DWARF scanner decides that this "main" is the main program and
	sets the current language to C++ at startup, causing this test to
	fail.

	This patch fixes the test in a simple way, by introducing a new
	function that takes the place of "main" in the DWARF.  I think this
	still exercises the original problem, but also avoids problems with my
	branch.

	It seemed safe to me to submit this separately.

	[gdb/testsuite] Use compiler-generated instead of gas-generated stabs
	The test-case gdb.dwarf2/dw2-ranges.exp is the only one in the gdb testsuite
	that uses gas-generated stabs.

	While the use seems natural alongside the use of gas-generated dwarf in the
	same test-case, there are a few known issues, filed on the gdb side as:
	- PR symtab/12497 - "stabs: PIE relocation does not work"
	- PR symtab/28221 - "[readnow, stabs] FAIL: gdb.dwarf2/dw2-ranges.exp: \
	  info line func"
	and on the gas side as:
	- PR gas/28233 - "[gas, --gstabs] Generate stabs more similar to gcc"

	The test-case contains a KFAIL for PR12497, but it's outdated and fails to
	trigger.

	The intention of the test-case is to test gas-generated dwarf, and using
	gcc-generated stabs instead of gas-generated stabs works fine.

	Supporting compiler-generated stabs is already a corner-case for gdb, and
	there's no current commitment/incentive to support/workaround gas-generated
	stabs, which can be considered a corner-case of a corner-case.

	Work around these problem by using compiler-generated stabs in the test-case.

	[gdb/testsuite] Add dummy start and end CUs in dwarf assembly
	Say one compiles a hello.c:
	...
	$ gcc -g hello.c
	...

	On openSUSE Leap 15.2 and Tumbleweed, the CU for hello.c is typically not the
	first in .debug_info, nor the last, due to presence of debug information in
	objects for sources like:
	- ../sysdeps/x86_64/start.S
	- init.c
	- ../sysdeps/x86_64/crti.S
	- elf-init.c
	- ../sysdeps/x86_64/crtn.S.

	On other systems, say ubuntu 18.04.5, the CU for hello.c is typically the
	first and the last in .debug_info.

	This difference has caused me to find some errors in the dwarf assembly
	using openSUSE, that didn't show up on other platforms.

	Force the same situation on other platforms by adding a dummy start
	and end CU.

	Tested on x86_64-linux.

	Fix register regression in DWARF evaluator
	On an internal test case, using an arm-elf target, commit ba5bc3e5a92
	("Make DWARF evaluator return a single struct value") causes a
	regression.  (It doesn't happen for any of the other cross targets
	that I test when importing upstream gdb.)

	I don't know if there's an upstream gdb test case showing the same
	problem... I can only really run native tests with dejagnu AFAIK.

	The failure manifests like this:

	    Breakpoint 1, file_1.export_1 (param_1=<error reading variable: Unable to access DWARF register number 64>, str=...) at [...]/file_1.adb:5

	Whereas when it works it looks like:

	    Breakpoint 1, file_1.export_1 (param_1=99.0, str=...) at [...]/file_1.adb:5

	The difference is that the new code uses the passed-in gdbarch,
	whereas the old code used the frame's gdbarch, when handling
	DWARF_VALUE_REGISTER.

	This patch restores the use of the frame's arch.

2021-08-16  Tom Tromey  <tromey@adacore.com>

	Fix Ada regression due to DWARF expression series
	Commit 0579205aec4 ("Simplify dwarf_expr_context class interface")
	caused a regression in the internal AdaCore test suite.  I didn't try
	to reproduce this with the GDB test suite, but the test is identical
	to gdb.dwarf2/dynarr-ptr.exp.

	The problem is that this change:

	 	case DW_OP_push_object_address:
	 	  /* Return the address of the object we are currently observing.  */
	-	  if (this->data_view.data () == nullptr
	-	      && this->obj_address == 0)
	+	  if (this->m_addr_info == nullptr)

	... slightly changes the logic here.  In particular, it's possible for
	the caller to pass in a non-NULL m_addr_info, but one that looks like:

	    (top) p *this.m_addr_info
	    $15 = {
	      type = 0x29b7a70,
	      valaddr = {
		m_array = 0x0,
		m_size = 0
	      },
	      addr = 0,
	      next = 0x0
	    }

	In this case, an additional check is needed.  With the current code,
	what happens instead is that the computation computes an incorrect
	address -- but one that does not fail in read_memory, due to the
	precise memory map of the embedded target in question.

	This patch restores the old logic.

	Notify observer of breakpoint auto-disabling
	As breakpoint_modified observer is currently notified upon breakpoint stop
	before handling auto-disabling when enable count is reached, the observer
	is never notified of the disabling.

	The problem affects:
	- The MI interpreter enabled= value when reporting =breakpoint-modified
	- A Python event handler for breakpoint_modified using the "enabled"
	  member of its parameter
	- insight: breakpoint GUI window is not properly updated upon auto-disable

	This patch moves the observer notification after the auto-disabling
	code and implements corresponding tests for the MI and Python cases.

	PR28217, Syntax error when memory region contains a hyphen
	The saga of commit 40726f16a8d7 continues.  This attacks the problem
	of switching between SCRIPT and EXPRESSION state lexing by removing
	the need to do so for phdrs like ":text".  Instead {WILDCHAR}*
	matching, the reason why ":text" lexed as one token, is restricted to
	within the braces of a section or overlay statement.  The new WILD
	lexer state is switched at the non-optional brace tokens, so
	ldlex_backup is no longer needed.  I've also removed the BOTH state,
	which doesn't seem to be needed any more.  Besides rules involving
	error reporting, there was just one place where SCRIPT appeared
	without BOTH, the {WILDCHAR}* rule, three where BOTH appears without
	SCRIPT for tokens that only need EXPRESSION state, and two where BOTH
	appears alongside INPUT_LIST.  (Since I'm editing the wild and
	filename rules, removing BOTH and adding WILD can also be seen as
	renaming the old BOTH state to SCRIPT and renaming the old SCRIPT
	state to WILD with a reduced scope.)

	As a followup, I'll look at removing EXPRESSION state from some lexer
	rules that no longer need it due to this cleanup.

	gdb: riscv_scan_prologue: handle LD and LW instructions
	While working on the testsuite, I ended up noticing that GDB fails to
	produce a full backtrace from a thread waiting in pthread_join.  When
	selecting the waiting thread and using the 'bt' command, the following
	result can be observed:

		(gdb) bt
		#0  0x0000003ff7fccd20 in __futex_abstimed_wait_common64 () from /lib/riscv64-linux-gnu/libpthread.so.0
		#1  0x0000003ff7fc43da in __pthread_clockjoin_ex () from /lib/riscv64-linux-gnu/libpthread.so.0
		Backtrace stopped: frame did not save the PC

	On my platform, I do not have debug symbols for glibc, so I need to rely
	on prologue analysis in order to unwind stack.

	Here is what the function prologue looks like:

		(gdb) disassemble __pthread_clockjoin_ex
		Dump of assembler code for function __pthread_clockjoin_ex:
		   0x0000003ff7fc42de <+0>:     addi    sp,sp,-144

		   0x0000003ff7fc4302 <+36>:    sd      a5,40(sp)

	As far as prologue analysis is concerned, the most interesting part is
	done at address 0x0000003ff7fc42ee (<+16>): 'sd ra,136(sp)'. This stores
	the RA (return address) register on the stack, which is the information
	we are looking for in order to identify the caller.

	In the current implementation of the prologue scanner, GDB stops when
	hitting 0x0000003ff7fc42e6 (<+8>) because it does not know what to do
	with the 'ld' instruction.  GDB thinks it reached the end of the
	prologue but have not yet reached the important part, which explain
	GDB's inability to unwind past this point.

	The section of the prologue starting at <+4> until <+12> is used to load
	the stack canary[1], which will then be placed on the stack at <+36> at
	the end of the prologue.

	In order to have the prologue properly handled, this commit proposes to
	add support for the ld instruction in the RISC-V prologue scanner.
	I guess riscv32 would use lw in such situation so this patch also adds
	support for this instruction.

	With this patch applied, gdb is now able to unwind past pthread_join:

		(gdb) bt
		#0  0x0000003ff7fccd20 in __futex_abstimed_wait_common64 () from /lib/riscv64-linux-gnu/libpthread.so.0
		#1  0x0000003ff7fc43da in __pthread_clockjoin_ex () from /lib/riscv64-linux-gnu/libpthread.so.0
		#2  0x0000002aaaaaa88e in bar() ()
		#3  0x0000002aaaaaa8c4 in foo() ()
		#4  0x0000002aaaaaa8da in main ()

	I have had a look to see if I could reproduce this easily, but in my
	simple testcases using '-fstack-protector-all', the canary is loaded
	after the RA register is saved.  I do not have a reliable way of
	generating a prologue similar to the problematic one so I forged one
	instead.

	The testsuite have been run on riscv64 ubuntu 21.01 with no regression
	observed.

	Improve forward progress test in python.exp
	The test steps into func2 and than does an up to get back to the previous
	frame. The test checks that the line number you are at after the up command
	is greater than the line where the function was called from. The
	assembly/codegen for the powerpc target includes a NOP after the
	branch-link.

	func2 (); /* Break at func2 call site. /
	10000694: 59 00 00 48 bl 100006ec
	10000698: 00 00 00 60 nop

	The PC at the instruction following the branch-link is 0x10000698 which
	GDB.find_pc_line() maps to the same line number as the bl instruction.
	GDB did move past the branch-link location thus making forward progress.

	The following proposed fix adds an additional PC check to see if forward
	progress was made.  The line test is changed from greater than to greater
	than or equal.

	Deprecate a.out support for NetBSD targets.
	As discussed previously, a.out support is now quite deprecated, and in
	some cases removed, in both Binutils itself and NetBSD, so this legacy
	default makes little sense. `netbsdelf*` and `netbsdaout*` still work
	allowing the user to be explicit about there choice. Additionally, the
	configure script warns about the change as Nick Clifton requested.

	One possible concern was the status of NetBSD on NS32K, where only a.out
	was supported. But per [1] NetBSD has removed support, and if it were to
	come back, it would be with ELF. The binutils implementation is
	therefore marked obsolete, per the instructions in the last message.

	With that patch and this one applied, I have confirmed the following:

	--target=i686-unknown-netbsd
	--target=i686-unknown-netbsdelf
	  builds completely

	--target=i686-unknown-netbsdaout
	  properly fails because target is deprecated.

	--target=vax-unknown-netbsdaout builds completely except for gas, where
	the target is deprecated.

	gdb: don't print backtrace when dumping core after an internal error
	Currently, when GDB hits an internal error, and the user selects to
	dump core, the recently added feature to write a backtrace to the
	console will kick in, and print a backtrace as well as dumping the
	core.

	This was certainly not my intention when adding the backtrace on fatal
	signal functionality, this feature was intended to produce a backtrace
	when GDB crashes due to some fatal signal, internal errors should have
	continued to behave as they did before, unchanged.

	In this commit I set the signal disposition of SIGABRT back to SIG_DFL
	just prior to the call to abort() that GDB uses to trigger the core
	dump, this prevents GDB reaching the code that writes the backtrace to
	the console.

	I've also added a test that checks we don't see a backtrace on the
	console after an internal error.

2021-08-11  Andrew Burgess  <andrew.burgess@embecosm.com>

	gdb: register SIGBUS, SIGFPE, and SIGABRT handlers
	Register handlers for SIGBUS, SIGFPE, and SIGABRT.  All of these
	signals are setup as fatal signals that will cause GDB to terminate.
	However, by passing these signals through the handle_fatal_signal
	function, a user can arrange to see a backtrace when GDB
	terminates (see maint set backtrace-on-fatal-signal).

	In normal use of GDB there should be no user visible changes after
	this commit.  Only if GDB terminates with one of the above signals
	will GDB change slightly, potentially printing a backtrace before
	aborting.

	I've added new tests for SIGFPE, SIGBUS, and SIGABRT.

2021-08-11  Andrew Burgess  <andrew.burgess@embecosm.com>

	gdb: print backtrace on fatal SIGSEGV
	This commit adds a new maintenance feature, the ability to print
	a (limited) backtrace if GDB dies due to a fatal signal.

	The backtrace is produced using the backtrace and backtrace_symbols_fd
	functions which are declared in the execinfo.h header, and both of
	which are async signal safe.  A configure check has been added to
	check for these features, if they are not available then the new code
	is not compiled into GDB and the backtrace will not be printed.

	The motivation for this new feature is to aid in debugging GDB in
	situations where GDB has crashed at a users site, but the user is
	reluctant to share core files, possibly due to concerns about what
	might be in the memory image within the core file.  Such a user might
	be happy to share a simple backtrace that was written to stderr.

	The production of the backtrace is on by default, but can switched off
	using the new commands:

	  maintenance set backtrace-on-fatal-signal on|off
	  maintenance show backtrace-on-fatal-signal

	Right now, I have hooked this feature in to GDB's existing handling of
	SIGSEGV only, but this will be extended to more signals in a later
	commit.

	One additional change I have made in this commit is that, when we
	decide GDB should terminate due to the fatal signal, we now
	raise the same fatal signal rather than raising SIGABRT.

	Currently, this is only effecting our handling of SIGSEGV.  So,
	previously, if GDB hit a SEGV then we would terminate GDB with a
	SIGABRT.  After this commit we will terminate GDB with a SIGSEGV.

	This feels like an improvement to me, we should still get a core dump,
	but in many shells, the user will see a more specific message once GDB
	exits, in bash for example "Segmentation fault" rather than "Aborted".

	Finally then, here is an example of the output a user would see if GDB
	should hit an internal SIGSEGV:

	  Fatal signal: Segmentation fault
	  ----- Backtrace -----
	  ./gdb/gdb[0x8078e6]
	  ./gdb/gdb[0x807b20]
	  /lib64/libpthread.so.0(+0x14b20)[0x7f6648c92b20]

	  ./gdb/gdb[0x41746e]
	  ---------------------
	  A fatal error internal to GDB has been detected, further
	  debugging is not possible.  GDB will now terminate.

	  This is a bug, please report it.  For instructions, see:
	  <https://www.gnu.org/software/gdb/bugs/>.

	  Segmentation fault (core dumped)

	It is disappointing that backtrace_symbols_fd does not actually map
	the addresses back to symbols, this appears, in part, to be due to GDB
	not being built with -rdynamic as the manual page for
	backtrace_symbols_fd suggests, however, even when I do add -rdynamic
	to the build of GDB I only see symbols for some addresses.

	We could potentially look at alternative libraries to provide the
	backtrace (e.g. libunwind) however, the solution presented here, which
	is available as part of glibc is probably a good baseline from which
	we might improve things in future.

	gdb: rename async_init_signals to gdb_init_signals
	The async_init_signals has, for some time, dealt with async and sync
	signals, so removing the async prefix makes sense I think.

	Additionally, as pointed out by Pedro:

	  .....

	The comments relating to SIGTRAP and SIGQUIT within this function are
	out of date.

	The comments for SIGTRAP talk about the signal disposition (SIG_IGN)
	being passed to the inferior, meaning the signal disposition being
	inherited by GDB's fork children.  However, we now call
	restore_original_signals_state prior to forking, so the comment on
	SIGTRAP is redundant.

	The comments for SIGQUIT are similarly out of date, further, the
	comment on SIGQUIT talks about problems with BSD4.3 and vfork,
	however, we have not supported BSD4.3 for several years now.

	Given the above, it seems that changing the disposition of SIGTRAP is
	no longer needed, so I've deleted the signal() call for SIGTRAP.

	Finally, the header comment on the function now called
	gdb_init_signals was getting quite out of date, so I've updated it
	to (hopefully) better reflect reality.

	There should be no user visible change after this commit.

2021-08-11  Andrew Burgess  <andrew.burgess@embecosm.com>

	gdb: register signal handler after setting up event token
	This commit fixes the smallest of small possible bug related to signal
	handling.  If we look in async_init_signals we see code like this:

	  signal (SIGQUIT, handle_sigquit);
	  sigquit_token =
	    create_async_signal_handler (async_do_nothing, NULL, "sigquit");

	Then if we look in handle_sigquit we see code like this:

	  mark_async_signal_handler (sigquit_token);
	  signal (sig, handle_sigquit);

	Finally, in mark_async_signal_handler we have:

	  async_handler_ptr->ready = 1;

	Where async_handler_ptr will be sigquit_token.

	What this means is that if a SIGQUIT arrive in async_init_signals
	after handle_sigquit has been registered, but before sigquit_token has
	been initialised, then GDB will most likely crash.

	The chance of this happening is tiny, but fixing this is trivial, just
	ensure we call create_async_signal_handler before calling signal, so
	lets do that.

	There are no tests for this.  Trying to land a signal in the right
	spot is pretty hit and miss.  I did try changing the current HEAD GDB
	like this:

	gdb: terminate upon receipt of SIGFPE
	GDB's SIGFPE handling is broken, this is PR gdb/16505 and
	PR gdb/17891.

	We currently try to use an async event token to process SIGFPE.  So,
	when a SIGFPE arrives the signal handler calls
	mark_async_signal_handler then returns, effectively ignoring the
	signal (for now).

	The intention is that later the event loop will see that the async
	token associated with SIGFPE has been marked and will call the async
	handler, which just throws an error.

	The problem is that SIGFPE is not safe to ignore.  Ignoring a
	SIGFPE (unless it is generated artificially, e.g. by raise()) is
	undefined behaviour, after ignoring the signal on many targets we
	return to the instruction that caused the SIGFPE to be raised, which
	immediately causes another SIGFPE to be raised, we get stuck in an
	infinite loop.  The behaviour is certainly true on x86-64.

	To view this behaviour I simply added some dummy code to GDB that
	performed an integer divide by zero, compiled this on x86-64
	GNU/Linux, ran GDB and saw GDB hang.

	In this commit, I propose to remove all special handling of SIGFPE and
	instead just let GDB make use of the default SIGFPE action, that is,
	to terminate the process.

	The only user visible change here should be:

	  - If a user sends a SIGFPE to GDB using something like kill,
	    previously GDB would just print an error and remain alive, now GDB
	    will terminate.  This is inline with what happens if the user
	    sends GDB a SIGSEGV from kill though, so I don't see this as an
	    issue.

	  - If a bug in GDB causes a real SIGFPE, previously the users GDB
	    session would hang.  Now the GDB session will terminate.  Again,
	    this is inline with what happens if GDB receives a SIGSEGV due to
	    an internal bug.

	In bug gdb/16505 there is mention that it would be nice if GDB did
	more than just terminate when receiving a fatal signal.  I haven't
	done that in this commit, but later commits will move in that
	direction.

	gas: fold IEEE encoding of -Inf with that of +Inf
	The respective results differ only by the sign bits - there's no need to

	gas: support NaN flavors
	Like for infinity, there isn't just a single NaN. The sign bit may be
	of interest and, going beyond infinity, whether the value is quiet or
	signalling may be even more relevant to be able to encode.

	Note that an anomaly with x86'es double extended precision NaN values
	gets taken care of at the same time: For all other formats a positive
	value with all mantissa bits set was used, while here a negative value
	with all non-significant mantissa bits clear was chose for an unknown
	reason.

	For m68k, since I don't know their X_PRECISION floating point value
	layout, a warning gets issued if any of the new flavors was attempted
	to be encoded that way. However likely it may be that, given that the
	code lives in a source file supposedly implementing IEEE-compliant
	formats, the bit patterns of the individual words match x86'es, I didn't
	want to guess so. And my very, very old paper doc doesn't even mention
	floating point formats other than single and double.

	wide (also adjusting documentation). This requires duplicating the
	definition of X_PRECISION in the target speciifc header; the compiler
	would complain if this was out of sync with config/atof-ieee.c.

	Note that for now padding space doesn't get separated from actual
	storage, which means that things will work correctly only for little-
	endian cases, and which also means that by specifying large enough
	numbers padding space can be set to non-zero. Since the logic is needed
	for a single little-endian architecture only for now, I'm hoping that
	this might be acceptable for the time being; otherwise the change will
	become more intrusive.

	Note also that this brings the emitted data size of .ds.x vs .tfloat in
	line for non-ELF targets as well; the issue will be even more obvious
	when further taking into account a subsequent patch fixing .dc.x/.dcb.x

	PR28163, Segment fault in function rl78_special_reloc

	gdb: iterate only on vfork parent threads in handle_vfork_child_exec_or_exit
	I spotted what I think is a buglet in proceed_after_vfork_done.  After a
	vfork child exits or execs, we resume all the threads of the parent.  To
	do so, we iterate on all threads using iterate_over_threads with the
	proceed_after_vfork_done callback.  Each thread is resumed if the
	following condition is true:

	    if (thread->ptid.pid () == pid
		&& thread->state == THREAD_RUNNING
		&& !thread->executing
		&& !thread->stop_requested
		&& thread->stop_signal () == GDB_SIGNAL_0)

	where `pid` is the pid of the vfork parent.  This is not multi-target
	aware: since it only filters on pid, if there is an inferior with the
	same pid in another target, we could end up resuming a thread of that
	other inferior.  The chances of the stars aligning for this to happen
	are tiny, but still.

	Fix that by iterating only on the vfork parent's threads, instead of on
	all threads.  This is more efficient, as we iterate on just the required
	threads (inferiors have their own thread list), and we can drop the pid
	check.  The resulting code is also more straightforward in my opinion,
	so it's a win-win.

	guile: fix smob exports
	Before Guile v2.1 [1], calls to `scm_make_smob_type' implicitly added
	the created class to the exports list of (oop goops); v2.1+ does not
	implicitly create bindings in any modules. This means that the GDB
	manual subsection documenting exported types is not quite right when GDB
	is linked against Guile <v2.1 (types are exported from (oop goops))
	instead of (gdb)) and incorrect when linked against Guile v2.1+ (types
	are not bound to any variables at all!).

	There is a range of cases in which it's necessary or convenient to be
	able to refer to a GDB smob type, for instance:

	 - Pattern matching based on the type of a value.
	 - Defining GOOPS methods handling values from GDB (GOOPS methods
	   typically use dynamic dispatch based on the types of the arguments).
	 - Type-checking assertions when applying some defensive programming on
	   an interface.
	 - Generally any other situation one might encounter in a dynamically
	   typed language that might need some introspection.

	If you're more familiar with Python, it would be quite similar to being
	unable to refer to the classes exported from the GDB module (which is to
	say: not crippling for the most part, but makes certain tasks more
	difficult than necessary).

	This commit makes a small change to GDB's smob registration machinery
	to make sure registered smobs get exported from the current
	module. This will likely cause warnings to the user about conflicting
	exports if they load both (gdb) and (oop goops) from a GDB linked
	against Guile v2.0, but it shouldn't impact functionality (and seemed
	preferable to trying to un-export bindings from (oop goops) if v2.0
	was detected).

	      /* A not-uncommon case of bad debug info.
	         Don't pollute the addrmap with bad data.  */
	      if (range_beginning + baseaddr == 0
	          && !per_objfile->per_bfd->has_section_at_zero)
	        {
	          complaint (_(".debug_rnglists entry has start address of zero"
	                       " [in module %s]"), objfile_name (objfile));
	          continue;
	        }
	...
	because baseaddr != 0, which seems incorrect given that when loading the
	shared library individually in gdb (and consequently baseaddr == 0), we do see
	the complaint.

	Consequently, we run into this case in dwarf2_get_pc_bounds:
	...
	  if (low == 0 && !per_objfile->per_bfd->has_section_at_zero)
	    return PC_BOUNDS_INVALID;
	...
	which then results in this code in process_psymtab_comp_unit_reader being
	called with cu_bounds_kind == PC_BOUNDS_INVALID, which sets the set_addrmap
	argument to 1:
	...
	      scan_partial_symbols (first_die, &lowpc, &highpc,
	                            cu_bounds_kind <= PC_BOUNDS_INVALID, cu);
	...
	and consequently, the CU addrmap gets build using address info from the
	functions.

	During that process, addrmap_set_empty is called with a range that includes
	0x9c218 and 0x9c21d:
	...
	(gdb) p /x start
	$7 = 0x9989c
	(gdb) p /x end_inclusive
	$8 = 0xb200d
	...
	but it's called for a function at DIE 0x54153 with DW_AT_ranges at 0x40ae:
	...
	    000040ae 00000000000b1ee0 00000000000b200e
	    000040b9 000000000009989c 00000000000998c4
	    000040c3 <End of list>
	...
	and neither range includes 0x9c218 and 0x9c21d.

	This is caused by this code in partial_die_info::read:
	...
	            if (dwarf2_ranges_read (ranges_offset, &lowpc, &highpc, cu,
	                                    nullptr, tag))
	             has_pc_info = 1;
	...
	which pretends that the function is located at addresses 0x9989c..0xb200d,
	which is indeed not the case.

	This patch fixes the first problem encountered: fix the "start address of
	zero" complaint warning by removing the baseaddr part from the condition.
	Same for dwarf2_ranges_process.

	The effect is that:
	- the complaint is triggered, and
	- the warning / Internal error is no longer triggered.

	This does not fix the observed problem in partial_die_info::read, which is
	filed as PR28200.

	Tested on x86_64-linux.

	gdb/testsuite: gdb.base/attach.exp: expose bug when testing with native-extended-gdbserver
	In gdb.base/attach.exp, proc do_attach_failure_tests, we attach to a
	process.  When then try to attach to the same process in another
	inferior, expecting it to fail.  We then come back to the first inferior
	and try to kill it, to clean up the test.  When using the
	native-extended-gdbserver board, this "kill" test passes, even though it
	didn't actually work:

	gdb/testsuite: gdb.base/attach.exp: fix support check in test_command_line_attach_run
	When running this test with the native-extended-gdbserver, we get:

	    main () at /home/simark/src/binutils-gdb/gdb/testsuite/gdb.base/attach.c:19
	    19	  while (! should_exit)
	    The program being debugged has been started already.
	    Start it from the beginning? (y or n) PASS: gdb.base/attach.exp: cmdline attach run: run to prompt
	    y
	    Don't know how to run.  Try "help target".
	    (gdb) FAIL: gdb.base/attach.exp: cmdline attach run: run to main

	This test tests using both "-p <pid>" and "-ex start" on the command line,
	making sure that we first attach and then run.

	Normally, after that "y", we should see the program running again.
	However, a particuliarity of the native-extended-gdbserver is that it
	uses "set auto-connect-native-target off" on the command line.  The full
	GDB command line is:

	    ./gdb -nw -nx -data-directory /home/simark/build/binutils-gdb/gdb/testsuite/../data-directory \
	          -iex set height 0 -iex set width 0 -ex set auto-connect-native-target off \
		  -ex set sysroot -quiet -iex set height 0 -iex set width 0 --pid=536609 -ex start

	The attach succeeds.  I guess it is done before "set
	auto-connect-native-target off", or it somehow bypasses it.  When the
	"start" is executed, the native target is unpushed, while killing the
	existing process, but not re-pushed, due to "set
	auto-connect-native-target off".  So we get that "Don't know how to run"
	message.

	Really, I think it's a case of the test doing things incompatible with
	the board, I think it should just be skipped.  And as we can see with
	the current code, there were some attempts at doing this, just using the
	wrong checks:

	 - isnative: this is a dejagnu proc which checks if the target board has
	   the same triplet as the build machine.  In the case of
	   native-extended-gdbserver, it does.
	 - is_remote target: this checks whether the target board is remote, as
	   in executing on a different machin.  native-extended-gdbserver is not
	   remote.

	Since the --pid option specifically attaches to a process using the
	native target, change the test to use gdb_is_target_native instead.

	gdb/testsuite/ChangeLog:

		* gdb.base/attach.exp (test_command_line_attach_run): Use
		gdb_is_target_native to check if test is supported.

	Simplify dwarf_expr_context class interface
	Idea of this patch is to get a clean and simple public interface for
	the dwarf_expr_context class, looking like:

	- constructor,
	- destructor,
	- push_address method and
	- evaluate method.

	Where constructor should only ever require a target architecture
	information. This information is held in per object file
	(dwarf2_per_objfile) structure, so it makes sense to keep that
	structure as a constructor argument. It also makes sense to get the
	address size from that structure, but unfortunately that interface
	doesn't exist at the moment, so the dwarf_expr_context class user
	needs to provide that information.

	The push_address method is used to push a CORE_ADDR as a value on
	top of the DWARF stack before the evaluation. This method can be
	later changed to push any struct value object on the stack.

	The evaluate method is the method that evaluates a DWARF expression
	and provides the evaluation result, in a form of a single struct
	value object that describes a location. To do this, the method requires
	a context of the evaluation, as well as expected result type
	information. If the type information is not provided, the DWARF generic
	type will be used instead.

	To avoid storing the gdbarch information in the evaluator object, that
	information is now always acquired from the per_objfile object.

	All data members are now private and only visible to the evaluator
	class, so a m_ prefix was added to all of their names to reflect that.
	To make this distinction clear, they are also accessed through objects
	this pointer, wherever that was not the case before.

	Move piece_closure and its support to expr.c
	Following 5 patches series is trying to clean up the interface of the
	DWARF expression evaluator class (dwarf_expr_context).

	After merging all expression evaluators into one class, the next
	logical step is to make a clean user interface for that class. To do
	that, we first need to address the issue of class users writing and
	reading the internal data of the class directly.

	Fixing the case of writing is simple, it makes sense for an evaluator
	instance to be per architecture basis. Currently, the best separation
	seems to be per object file, so having that data (dwarf2_per_objfile)
	as a constructor argument makes sense. It also makes sense to get the
	address size from that object file, but unfortunately that interface
	does not exist at the moment.

	Luckily, address size information is already available to the users
	through other means. As a result, the address size also needs to be a
	class constructor argument, at least until a better interface for
	acquiring that information from an object file is implemented.

	The rest of the user written data comes down to a context of an
	evaluated expression (compilation unit context, frame context and
	passed in buffer context) and a source type information that a result
	of evaluating expression is representing. So, it makes sense for all of
	these to be arguments of an evaluation method.

	To address the problem of reading the dwarf_expr_context class
	internal data, we first need to understand why it is implemented that
	way?

	This is actualy a question of which existing class can be used to
	represent both values and a location descriptions and why it is not
	used currently?

	The answer is in a struct value class/structure, but the problem is
	that before the evaluators were merged, only one evaluator had an
	infrastructure to resolve composite and implicit pointer location
	descriptions.

	After the merge, we are now able to use the struct value to represent
	any result of the expression evaluation. It also makes sense to move
	all infrastructure for those location descriptions to the expr.c file
	considering that that is the only place using that infrastructure.

	What we are left with in the end is a clean public interface of the
	dwarf_expr_context class containing:

	- constructor,
	- destructor,
	- push_address method and
	- eval_exp method.

	The idea with this particular patch is to move piece_closure structure
	and the interface that handles it (lval_funcs) to expr.c file.

	While implicit pointer location descriptions are still not useful in
	the CFI context (of the AMD's DWARF standard extensions), the composite
	location descriptions are certainly necessary to describe a results of
	specific compiler optimizations.

	Considering that a piece_closure structure is used to represent both,
	there was no benefit in splitting them.

	Merge evaluate_for_locexpr_baton evaluator
	The evaluate_for_locexpr_baton is the last derived class from the
	dwarf_expr_context class. It's purpose is to support the passed in
	buffer functionality.

	Although, it is not really necessary to merge this class with it's
	base class, doing that simplifies new expression evaluator design.

	Considering that this functionality is going around the DWARF standard,
	it is also reasonable to expect that with a new evaluator design and
	extending the push object address functionality to accept any location
	description, there will be no need to support passed in buffers.

	Alternatively, it would also makes sense to abstract the interaction
	between the evaluator and a given resource in the near future. The
	passed in buffer would then be a specialization of that abstraction.

	gdb/ChangeLog:

		* dwarf2/expr.c (dwarf_expr_context::read_mem): Merge with
		evaluate_for_locexpr_baton implementation.
		* dwarf2/loc.c (class evaluate_for_locexpr_baton): Remove
		class.
		(evaluate_for_locexpr_baton::read_mem): Move to
		dwarf_expr_context.
		(dwarf2_locexpr_baton_eval): Instantiate dwarf_expr_context
		instead of evaluate_for_locexpr_baton class.

	Remove empty frame and full evaluators
	There are no virtual methods that require different specialization in
	dwarf_expr_context class. This means that derived classes
	dwarf_expr_executor and dwarf_evaluate_loc_desc are not needed any
	more.

	As a result of this, the  evaluate_for_locexpr_baton class base class
	is now the dwarf_expr_context class.

	There might be a need for a better class hierarchy when we know more
	about the direction of the future DWARF versions and gdb extensions,
	but that is out of the scope of this patch series.

	Move frame context info to dwarf_expr_context
	Following 15 patches in this patch series is cleaning up the design of
	the DWARF expression evaluator (dwarf_expr_context) to make future
	extensions of that evaluator easier and cleaner to implement.

	There are three subclasses of the dwarf_expr_context class
	(dwarf_expr_executor, dwarf_evaluate_loc_desc and
	evaluate_for_locexpr_baton). Here is a short description of each class:

	- dwarf_expr_executor is evaluating a DWARF expression in a context
	  of a Call Frame Information. The overridden methods of this subclass
	  report an error if a specific DWARF operation, represented by that
	  method, is not allowed in a CFI context. The source code of this
	  subclass lacks the support for composite as well as implicit pointer
	  location description.

	- dwarf_evaluate_loc_desc can evaluate any expression with no
	  restrictions. All of the methods that this subclass overrides are
	  actually doing what they are intended to do. This subclass contains
	  a full support for all location description types.

	- evaluate_for_locexpr_baton subclass is a specialization of the
	  dwarf_evaluate_loc_desc subclass and it's function is to add
	  support for passed in buffers. This seems to be a way to go around
	  the fact that DWARF standard lacks a bit offset support for memory
	  location descriptions as well as using any location description for
	  the push object address functionality.

	It all comes down to this question: what is a function of a DWARF
	expression evaluator?

	Is it to evaluate the expression in a given context or to check the
	correctness of that expression in that context?

	Currently, the only reason why there is a dwarf_expr_executor subclass
	is to report an invalid DWARF expression in a context of a CFI, but is
	that what the evaluator is supposed to do considering that the evaluator
	is not tied to a given DWARF version?

	There are more and more vendor and GNU extensions that are not part of
	the DWARF standard, so is it that impossible to expect that some of the
	extensions could actually lift the previously imposed restrictions of
	the CFI context? Not to mention that every new DWARF version is lifting
	some restrictions anyway.

	The thing that makes more sense for an evaluator to do, is to take the
	context of an evaluation and checks the requirements of every operation
	evaluated against that context. With this approach, the evaluator would
	report an error only if parts of the context, necessary for the
	evaluation, are missing.

	If this approach is taken, then the unification of the
	dwarf_evaluate_loc_desc, dwarf_expr_executor and dwarf_expr_context
	is the next logical step. This makes a design of the DWARF expression
	evaluator cleaner and allows more flexibility when supporting future
	vendor and GNU extensions.

	Additional benefit here is that now all evaluators have access to all
	location description types, which means that a vendor extended CFI
	rules could support composite location description as well. This also
	means that a new evaluator interface can be changed to return a single
	struct value (that describes the result of the evaluation) instead of
	a caller poking around the dwarf_expr_context internal data for answers
	(like it is done currently).

	This patch starts the merging process by moving the frame context
	information and support from dwarf_expr_executor and
	dwarf_evaluate_loc_desc to dwarf_expr_context evaluator. The idea
	is to report an error when a given operation requires a frame
	information to be resolved, if that information is not present.

	Replace the symbol needs evaluator with a parser
	This patch addresses a design problem with the symbol_needs_eval_context
	class. It exposes the problem by introducing two new testsuite test
	cases.

	To explain the issue, I first need to explain the dwarf_expr_context
	class that the symbol_needs_eval_context class derives from.

	The intention behind the dwarf_expr_context class is to commonize the
	DWARF expression evaluation mechanism for different evaluation
	contexts. Currently in gdb, the evaluation context can contain some or
	all of the following information: architecture, object file, frame and
	compilation unit.

	Depending on the information needed to evaluate a given expression,
	there are currently three distinct DWARF expression evaluators:

	 - Frame: designed to evaluate an expression in the context of a call
	   frame information (dwarf_expr_executor class). This evaluator doesn't
	   need a compilation unit information.

	 - Location description: designed to evaluate an expression in the
	   context of a source level information (dwarf_evaluate_loc_desc
	   class). This evaluator expects all information needed for the
	   evaluation of the given expression to be present.

	 - Symbol needs: designed to answer a question about the parts of the
	   context information required to evaluate a DWARF expression behind a
	   given symbol (symbol_needs_eval_context class). This evaluator
	   doesn't need a frame information.

	The functional difference between the symbol needs evaluator and the
	others is that this evaluator is not meant to interact with the actual
	target. Instead, it is supposed to check which parts of the context
	information are needed for the given DWARF expression to be evaluated by
	the location description evaluator.

	The idea is to take advantage of the existing dwarf_expr_context
	evaluation mechanism and to fake all required interactions with the
	actual target, by returning back dummy values. The evaluation result is
	returned as one of three possible values, based on operations found in a
	given expression:

	- SYMBOL_NEEDS_NONE,
	- SYMBOL_NEEDS_REGISTERS and
	- SYMBOL_NEEDS_FRAME.

	The problem here is that faking results of target interactions can yield
	an incorrect evaluation result.

	For example, if we have a conditional DWARF expression, where the
	condition depends on a value read from an actual target, and the true
	branch of the condition requires a frame information to be evaluated,
	while the false branch doesn't, fake target reads could conclude that a
	frame information is not needed, where in fact it is. This wrong
	information would then cause the expression to be actually evaluated (by
	the location description evaluator) with a missing frame information.
	This would then crash the debugger.

	The gdb.dwarf2/symbol_needs_eval_fail.exp test introduces this
	scenario, with the following DWARF expression:

	                   DW_OP_addr $some_variable
	                   DW_OP_deref

	                   # conditional jump to DW_OP_bregx
	                   DW_OP_bra 4
	                   DW_OP_lit0

	                   # jump to DW_OP_stack_value
	                   DW_OP_skip 3
	                   DW_OP_bregx $dwarf_regnum 0
	                   DW_OP_stack_value

	This expression describes a case where some variable dictates the
	location of another variable. Depending on a value of some_variable, the
	variable whose location is described by this expression is either read
	from a register or it is defined as a constant value 0. In both cases,
	the value will be returned as an implicit location description on the
	DWARF stack.

	Currently, when the symbol needs evaluator fakes a memory read from the
	address behind the some_variable variable, the constant value 0 is used
	as the value of the variable A, and the check returns the
	SYMBOL_NEEDS_NONE result.

	This is clearly a wrong result and it causes the debugger to crash.

	The scenario might sound strange to some people, but it comes from a
	SIMD/SIMT architecture where $some_variable is an execution mask.  In
	any case, it is a valid DWARF expression, and GDB shouldn't crash while
	evaluating it. Also, a similar example could be made based on a
	condition of the frame base value, where if that value is concluded to
	be 0, the variable location could be defaulted to a TLS based memory
	address.

	The gdb.dwarf2/symbol_needs_eval_timeout.exp test introduces a second
	scenario. This scenario is a bit more abstract due to the DWARF
	assembler lacking the CFI support, but it exposes a different
	manifestation of the same problem. Like in the previous scenario, the
	DWARF expression used in the test is valid:

	                       DW_OP_lit1
	                       DW_OP_addr $some_variable
	                       DW_OP_deref

	                       # jump to DW_OP_fbreg
	                       DW_OP_skip 4
	                       DW_OP_drop
	                       DW_OP_fbreg 0
	                       DW_OP_dup
	                       DW_OP_lit0
	                       DW_OP_eq

	                       # conditional jump to DW_OP_drop
	                       DW_OP_bra -9
	                       DW_OP_stack_value

	Similarly to the previous scenario, the location of a variable A is an
	implicit location description with a constant value that depends on a
	value held by a global variable. The difference from the previous case
	is that DWARF expression contains a loop instead of just one branch. The
	end condition of that loop depends on the expectation that a frame base
	value is never zero. Currently, the act of faking the target reads will
	cause the symbol needs evaluator to get stuck in an infinite loop.

	Somebody could argue that we could change the fake reads to return
	something else, but that would only hide the real problem.

	The general impression seems to be that the desired design is to have
	one class that deals with parsing of the DWARF expression, while there
	are virtual methods that deal with specifics of some operations.

	Using an evaluator mechanism here doesn't seem to be correct, because
	the act of evaluation relies on accessing the data from the actual
	target with the possibility of skipping the evaluation of some parts of
	the expression.

	To better explain the proposed solution for the issue, I first need to
	explain a couple more details behind the current design:

	There are multiple places in gdb that handle DWARF expression parsing
	for different purposes. Some are in charge of converting the expression
	to some other internal representation (decode_location_expression,
	disassemble_dwarf_expression and dwarf2_compile_expr_to_ax), some are
	analysing the expression for specific information
	(compute_stack_depth_worker) and some are in charge of evaluating the
	expression in a given context (dwarf_expr_context::execute_stack_op
	and decode_locdesc).

	The problem is that all those functions have a similar (large) switch
	statement that handles each DWARF expression operation. The result of
	this is a code duplication and harder maintenance.

	As a step into the right direction to solve this problem (at least for
	the purpose of a DWARF expression evaluation) the expression parsing was
	commonized inside of an evaluator base class (dwarf_expr_context). This
	makes sense for all derived classes, except for the symbol needs
	evaluator (symbol_needs_eval_context) class.

	As described previously the problem with this evaluator is that if the
	evaluator is not allowed to access the actual target, it is not really
	evaluating.

	Instead, the desired function of a symbol needs evaluator seems to fall
	more into expression analysis category. This means that a more natural
	fit for this evaluator is to be a symbol needs analysis, similar to the
	existing compute_stack_depth_worker analysis.

	Another problem is that using a heavyweight mechanism of an evaluator
	to do an expression analysis seems to be an unneeded overhead. It also
	requires a more complicated design of the parent class to support fake
	target reads.

	The reality is that the whole symbol_needs_eval_context class can be
	replaced with a lightweight recursive analysis function, that will give
	more correct result without compromising the design of the
	dwarf_expr_context class. The analysis treats the expression byte
	stream as a DWARF operation graph, where each graph node can be
	visited only once and each operation can decide if the frame context
	is needed for their evaluation.

	The downside of this approach is adding of one more similar switch
	statement, but at least this way the new symbol needs analysis will be
	a lightweight mechnism and it will provide a correct result for any
	given DWARF expression.

	A more desired long term design would be to have one class that deals
	with parsing of the DWARF expression, while there would be a virtual
	methods that deal with specifics of some DWARF operations. Then that
	class would be used as a base for all DWARF expression parsing mentioned
	at the beginning.

	This however, requires a far bigger changes that are out of the scope
	of this patch series.

	The new analysis requires the DWARF location description for the
	argc argument of the main function to change in the assembly file
	gdb.python/amd64-py-framefilter-invalidarg.S. Originally, expression
	ended with a 0 value byte, which was never reached by the symbol needs
	evaluator, because it was detecting a stack underflow when evaluating
	the operation before. The new approach does not simulate a DWARF
	stack anymore, so the 0 value byte needs to be removed because it
	makes the DWARF expression invalid.

	[PATCH 2/2] Add tests for Intel AVX512_FP16 instructions
	Intel AVX512 FP16 instructions use maps 3, 5 and 6. Maps 5 and 6 use 3 bits
	in the EVEX.mmm field (0b101, 0b110). Map 5 is for instructions that were FP32
	in map 1 (0Fxx). Map 6 is for instructions that were FP32 in map 2 (0F38xx).
	There are some exceptions to this rule. Some things in map 1 (0Fxx) with imm8
	operands predated our current conventions; those instructions moved to map 3.
	FP32 things in map 3 (0F3Axx) found new opcodes in map3 for FP16 because map3
	is very sparsely populated. Most of the FP16 instructions share opcodes and
	prefix (EVEX.pp) bits with the related FP32 operations.

	Intel AVX512 FP16 instructions has new displacements scaling rules, please refer
	to the public software developer manual for detail information.

	gdb/testsuite: update test gdb.base/step-over-syscall.exp
	I was looking at PR gdb/19675 and the related test
	gdb.base/step-over-syscall.exp.  This test includes a call to kfail
	when we are testing a displaced step over a clone syscall.

	While looking at the test I removed the call to kfail and ran the
	test, and was surprised that the test passed.

	I ran the test a few times and it does sometimes fail, but mostly it
	passed fine.

	PR gdb/19675 describes how, when we displaced step over a clone, the
	new thread is created with a $pc in the displaced step buffer.  GDB
	then fails to "fix" this $pc (for the new thread), and the thread will
	be set running with its current $pc value.  This means that the new
	thread will just start executing from whatever happens to be after the
	displaced stepping buffer.

	In the original PR gdb/19675 bug report Yao Qi was seeing the new
	thread cause a segfault, the problem is, what actually happens is
	totally undefined.

	On my machine, I'm seeing the new thread reenter main, it then starts
	trying to run the test again (in the new thread).  This just happens
	to be safe enough (in this simple test) that most of the time the
	inferior doesn't crash.

	In this commit I try to make the test slightly more likely to fail by
	doing a couple of things.

	First, I added a static variable to main, this is set true when the
	first thread enters main, if a second thread ever enters main then I
	force an abort.

	Second, when the test is finishing I want to ensure that the new
	threads have had a chance to do "something bad" if they are going to.
	So I added a global counter, as each thread starts successfully it
	decrements the counter.  The main thread does not proceed to the final
	marker function (where GDB has placed a breakpoint) until all threads
	have started successfully.  This means that if the newly created
	thread doesn't successfully enter clone_fn then the counter will never
	reach zero and the test will timeout.

	With these two changes my hope is that the test should fail more
	reliably, and so, I have also changed the test to call setup_kfail
	before the specific steps that we expect to misbehave instead of just
	calling kfail and skipping parts of the test completely.  The benefit
	of this is that if/when we fix GDB this test will start to KPASS and
	we'll know to update this test to remove the setup_kfail call.

	gdb: Use unwinder name in frame_info::to_string
	While working on a stack unwinding issue using 'set debug frame on', I
	noticed the frame_info::to_string method could be slightly improved.

	Unwinders have been given a name in
	a154d838a70e96d888620c072e2d6ea8bdf044ca.  Before this patch, frame_info
	debug output prints the host address of the used unwinder, which is not
	easy to interpret.  This patch proposes to use the unwinder name
	instead since we now have it.

	Before the patch:

	    {level=1,type=NORMAL_FRAME,unwind=0x2ac1763ec0,pc=0x3ff7fc3460,id={stack=0x3ff7ea79b0,code=0x0000003ff7fc33ac,!special},func=0x3ff7fc33ac}

	With the patch:

	    {level=1,type=NORMAL_FRAME,unwinder="riscv prologue",pc=0x3ff7fc3460,id={stack=0x3ff7ea79b0,code=0x0000003ff7fc33ac,!special},func=0x3ff7fc33ac}

	Tested on riscv64-linux-gnu.

	gdb/testsuite: fix gdb.base/info-macros.exp with clang
	The test gdb.base/info-macros.exp says that it doesn't pass the "debug"
	option to prepare_for_testing because that would cause -g to appear
	after -g3 on the command line, and that would cause some gcc versions to
	not include macro info.  I don't know what gcc versions this refers to.
	I tested with gcc 4.8, and that works fine with -g after -g3.

	The current state is problematic when testing with CC_FOR_TARGET=clang,
	because then only -fdebug-macro is included.  No -g switch if included,
	meaning we get a binary without any debug info, and the test fails.

	One way to fix it would be to add "debug" to the options when the
	compiler is clang.

	However, the solution I chose was to specify "debug" in any case, even
	for gcc.  Other macro tests such as gdb.base/macscp.exp do perfectly
	fine with it.  Also, this lets the test use the debug flag specified by
	the board file.  For example, we can test with GCC and DWARF 5, with:

	    $ make check RUNTESTFLAGS="--target_board unix/gdb:debug_flags=-gdwarf-5" TESTS="gdb.base/info-macros.exp"

	With the hard-coded -g3, this wouldn't actually test with DWARF 5.

	gdb: avoid dereferencing empty str_offsets_base optional in dwarf_decode_macros
	Since 4d7188abfdf2 ("gdbsupport: add debug assertions in
	gdb::optional::get"), some macro-related tests fail on Ubuntu 20.04 with
	the system gcc 9.3.0 compiler when building with _GLIBCXX_DEBUG.  For
	example, gdb.base/info-macros.exp results in:

	   (gdb) break -qualified main
	   /home/smarchi/src/binutils-gdb/gdb/../gdbsupport/gdb_optional.h:206: internal-error: T& gdb::optional<T>::get() [with T = long unsigned int]: Assertion `this->has_value ()' failed.

	The binary contains DWARF 4 debug info and includes a pre-standard
	(pre-DWARF 5) .debug_macro section.  The CU doesn't have a
	DW_AT_str_offsets_base attribute (which doesn't exist in DWARF 4).  The
	field dwarf2_cu::str_offsets_base is therefore empty.  At
	dwarf2/read.c:24138, we unconditionally read the value in the optional,
	which triggers the assertion shown above.

	The same thing happens when building the test program with DWARF 5 with
	the same gcc compiler, as that version of gcc doesn't use indirect
	string forms, even with DWARF 5.  So it still doesn't add a
	DW_AT_str_offsets_base attribute on the CU.

	Fix that by propagating down a gdb::optional<ULONGEST> for the str
	offsets base instead of ULONGEST.  That value is only used in
	dwarf_decode_macro_bytes, when encountering an "strx" macro operation
	(DW_MACRO_define_strx or DW_MACRO_undef_strx).  Add a check there that
	we indeed have a value in the optional before reading it.  This is
	unlikely to happen, but could happen in theory with an erroneous file
	that uses DW_MACRO_define_strx but does not provide a
	DW_AT_str_offsets_base (in practice, some things would probably have
	failed before and stopped processing of debug info).  I tested the
	complaint by inverting the condition and using a clang-compiled binary,
	which uses the strx operators.  This is the result:

	    During symbol reading: use of DW_MACRO_define_strx with unknown string offsets base [in module /home/simark/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/info-macros/info-macros]

	The test now passes cleanly with the setup mentioned above, and the
	testsuite looks on par with how it was before 4d7188abfdf2.

	Fix it, and while at it mention DW_MACRO as well (it would be confusing

	PR28162, segment fault in mips_elf_assign_gp
	For the testcase in the PR, _bfd_mips_elf32_gprel16_reloc is passed a
	NULL output_bfd.  As expected for reloc special functions if called by
	objdump or when final linking.  The function attempts to find the
	output by
	  output_bfd = symbol->section->output_section->owner;
	That makes some sense, since when handling a gp-relative reloc we need
	the relevant gp to which the symbol is relative.  Possibly the gp
	value can be one for a shared library?  But that doesn't seem useful
	or supported by the various abi docs and won't work as written.
	Symbols defined in shared libraries have section->output_section
	NULL, and what's more the code in mips_elf_assign_gp isn't set up to
	look at shared library symbols.

	Also, if the symbol is a SHN_ABS one the owner of *ABS* section is
	NULL, which will result in the testcase segfault.  The only gp to
	which an absolute symbol can be relative is the linker output bfd when
	linking, or the input bfd when not.  This patch arranges to do that
	for all gp-relative reloc symbols.

	[gdb/symtab] Implement addrmap_mutable_find
	Currently addrmap_mutable_find is not implemented:
	...
	static void *
	addrmap_mutable_find (struct addrmap *self, CORE_ADDR addr)
	{
	  /* Not needed yet.  */
	  internal_error (__FILE__, __LINE__,

	                    "for mutable addrmaps"));
	}
	...

	I implemented this because I needed it during debugging, to be able to do:
	...
	(gdb) p ((dwarf2_psymtab *)addrmap_find (map, addr))->filename
	...
	before and after a call to addrmap_set_empty.

	Since this is not used otherwise, added addrmap unit test.

	gdb: follow-fork: push target and add thread in target_follow_fork
	In the context of ROCm-gdb [1], the ROCm target sits on top of the
	linux-nat target.  when a process forks, it needs to carry over some
	data from the forking inferior to the fork child inferior.  Ideally, the
	ROCm target would implement the follow_fork target_ops method, but there
	are some small problems.  This patch fixes these, which helps the ROCm
	target, but also makes things more consistent and a bit nicer in
	general, I believe.

	The main problem is: when follow-fork-mode is "parent",
	target_follow_fork is called with the parent as the current inferior.
	When it's "child", target_follow_fork is called with the child as the
	current inferior.  This means that target_follow_fork is sometimes
	called on the parent's target stack and sometimes on the child's target
	stack.

	The parent's target stack may contain targets above the process target,
	such as the ROCm target.  So if follow-fork-child is "parent", the ROCm
	target would get notified of the fork and do whatever is needed.  But
	the child's target stack, at that moment, only contains the exec and
	process target copied over from the parent.  The child's target stack is
	set up by follow_fork_inferior, before calling target_follow_fork.  In
	that case, the ROCm target wouldn't get notified of the fork.

	For consistency, I think it would be good to always call
	target_follow_fork on the parent inferior's target stack.  I think it
	makes sense as a way to indicate "this inferior has called fork, do
	whatever is needed".  The desired outcome of the fork (whether an
	inferior is created for the child, do we need to detach from the child)
	can be indicated by passed parameter.

	I therefore propose these changes:

	 - make follow_fork_inferior always call target_follow_fork with the
	   parent as the current inferior.  That lets all targets present on the
	   parent's target stack do some fork-related handling and push
	   themselves on the fork child's target stack if needed.

	   For this purpose, pass the child inferior down to target_follow_fork
	   and follow_fork implementations.  This is nullptr if no inferior is
	   created for the child, because we want to detach from it.

	 - as a result, in follow_fork_inferior, detach from the parent inferior
	   (if needed) only after the target_follow_fork call.  This is needed
	   because we want to call target_follow_fork before the parent's
	   target stack is torn down.

	 - hand over to the targets in the parent's target stack (including the
	   process target) the responsibility to push themselves, if needed, to
	   the child's target stack.  Also hand over the responsibility to the
	   process target, at the same time, to create the child's initial
	   thread (just like we do for follow_exec).

	 - pass the child inferior to exec_on_vfork, so we don't need to swap
	   the current inferior between parent and child.  Nothing in
	   exec_on_vfork depends on the current inferior, after this change.

	   Although this could perhaps be replaced with just having the exec
	   target implement follow_fork and push itself in the child's target
	   stack, like the process target does... We would just need to make
	   sure the process target calls beneath()->follow_fork(...).  I'm not
	   sure about this one.

	gdbsupport: add debug assertions in gdb::optional::get
	The libstdc++ version of optional contains some runtime checks enabled
	when _GLIBCXX_DEBUG is defined.  I think it would be useful if our
	version contained similar checks.

	Add checks in the two `get` methods, also conditional on _GLIBCXX_DEBUG.
	I think it's simpler to use that macro rather than introducing a new
	GDB-specific one, as I think that if somebody is interested in enabling
	these runtime checks, they'll also be interested in enabling the
	libstdc++ runtime checks (and vice-versa).

	I implemented these checks using gdb_assert.  Note that gdb_assert
	throws (after querying the user), and we are in noexcept methods.  That
	means that std::terminate / abort will immediately be called.  I think
	this is ok, since if those were "real" _GLIBCXX_DEBUG checks, abort
	would be called straight away.

	If I add a dummy failure, it looks like so:

	    $ ./gdb -q -nx --data-directory=data-directory
	    /home/simark/src/binutils-gdb/gdb/../gdbsupport/gdb_optional.h:206: internal-error: T& gdb::optional<T>::get() [with T = int]: Assertion `this->has_value ()' failed.

	Handle compiler-generated suffixes in Ada names
	The compiler may add a suffix to a mangled name.  A typical example
	would be splitting a function and creating a ".cold" variant.

	This patch changes Ada decoding (aka demangling) to handle these
	suffixes.  It also changes the encoding process to handle them as
	well.

	A symbol like "function.cold" will now be displayed to the user as
	"function[cold]".  The "." is not simply preserved because that is
	already used in Ada.

2021-08-02  Tom Tromey  <tromey@adacore.com>

	Remove uses of fprintf_symbol_filtered
	I believe that many calls to fprintf_symbol_filtered are incorrect.
	In particular, there are some that pass a symbol's print name, like:

	  fprintf_symbol_filtered (gdb_stdout, sym->print_name (),
				   current_language->la_language, DMGL_ANSI);

	fprintf_symbol_filtered uses the "demangle" global to decide whether
	or not to demangle -- but print_name does this as well.  This can lead
	to double-demangling.  Normally this could be innocuous, except I also
	plan to change Ada demangling in a way that causes this to fail.

	Handle type qualifier for enumeration name
	Pierre-Marie noticed that the Ada expression "TYPE'(NAME)" resolved
	incorrectly when "TYPE" was an enumeration type.  Here, "NAME" should
	be unambiguous.

	This patch fixes this problem.  Note that the patch is not perfect --
	it does not give an error if TYPE is an enumeration type but NAME is
	not an enumerator but does have some other meaning in scope.  Fixing
	this proved difficult, and so I've left it out.

2021-08-02  Tom Tromey  <tromey@adacore.com>

	Remove the type_qualifier global
	The type_qualifier global is no longer needed in the Ada expression
	parser, so this removes it.

2021-08-02  Tom Tromey  <tromey@adacore.com>

	Defer Ada character literal resolution
	In Ada, an enumeration type can use a character literal as one of the
	enumerators.  The Ada expression parser handles the appropriate
	conversion.

	It turns out, though, that this conversion was handled incorrectly.
	For an expression like TYPE'(EXP), the conversion would be done for
	any such literal appearing in EXP -- but only the outermost such
	expression should really be affected.

	This patch defers the conversion until the resolution phase, fixing
	the bug.

2021-08-02  Tom Tromey  <tromey@adacore.com>

	Refactor Ada resolution
	In a subsequent patch, it will be convenient if an Ada expression
	operation can supply its own replacement object.  This patch refactors
	Ada expression resolution to make this possible.

	Remove add_symbols_from_enclosing_procs
	I noticed that add_symbols_from_enclosing_procs is empty, and can be
	removed.  The one caller, ada_add_local_symbols, can also be
	simplified, removing some code that, I think, was an incorrect attempt
	to handle nested functions.

	Avoid crash in varobj deletion
	PR varobj/28131 points out a crash in the varobj deletion code.  It
	took a while to reproduce this, but essentially what happens is that a
	top-level varobj deletes its root object, then deletes the "dynamic"
	object.  However, deletion of the dynamic object may cause
	~py_varobj_iter to run, which in turn uses gdbpy_enter_varobj:

	gdbpy_enter_varobj::gdbpy_enter_varobj (const struct varobj *var)
	: gdbpy_enter (var->root->exp->gdbarch, var->root->exp->language_defn)
	{
	}

	However, because var->root has already been destroyed, this is
	invalid.

	I've added a new test case.  This doesn't reliably crash, but the
	problem can easily be seen under valgrind (and, I presume, with ASAN,
	though I did not try this).

	Tested on x86-64 Fedora 32.  I also propose putting this on the GDB 11
	branch, with a suitable ChangeLog entry of course.

	gdb: Make the builtin "boolean" type an unsigned type
	When printing the fields of a register that is of a custom struct type,
	the "unpack_bits_as_long ()" function is used:

	    do_val_print (...)
	      cp_print_value_fields (...)
	        value_field_bitfield (...)
	          unpack_value_bitfield (...)
	            unpack_bits_as_long (...)

	This function may sign-extend the extracted field while returning it:

	    val >>= lsbcount;

	    if (...)
	      {
	        valmask = (((ULONGEST) 1) << bitsize) - 1;
	        val &= valmask;
	        if (!field_type->is_unsigned ())
	  	  if (val & (valmask ^ (valmask >> 1)))
	  	      val |= ~valmask;
	      }

	    return val;

	lsbcount:   Number of lower bits to get rid of.
	bitsize:    The bit length of the field to be extracted.
	val:        The register value.
	field_type: The type of field that is being handled.

	While the logic here is correct, there is a problem when it is
	handling "field_type"s of "boolean".  Those types are NOT marked
	as "unsigned" and therefore they end up being sign extended.
	Although this is not a problem for "false" (0), it definitely
	causes trouble for "true".

	This patch constructs the builtin boolean type as such that it is
	marked as an "unsigned" entity.

	The issue tackled here was first encountered for arc-elf32 target
	running on an x86_64 machine.  The unit-test introduced in this change
	has passed for all the targets (--enable-targets=all) running on the
	same x86_64 host.

	[gdb/build] Disable attribute nonnull
	With trunk gcc (12.0) we're running into a -Werror=nonnull-compare build
	breaker in gdb, which caused a broader review of the usage of the nonnull
	attribute.

	The current conclusion is that it's best to disable this.  This is explained
	at length in the gdbsupport/common-defs.h comment.

	gdb: fix nr_bits gdb_assert in append_flags_type_field
	The assertion

	    gdb_assert (nr_bits >= 1 && nr_bits <= type_bitsize);

	is not correct.  Well, it's correct in that we do want the number of
	bits to be in the range [1, type_bitsize].  But we don't check anywhere
	that the end of the specified flag is within the containing type.

	The following code should generate a failed assertion, as the flag goes
	past the 32 bits of the underlying type, but it's currently not caught:

	    static void
	    test_print_flag (gdbarch *arch)
	    {
	      type *flags_type = arch_flags_type (arch, "test_type", 32);
	      type *field_type = builtin_type (arch)->builtin_uint32;
	      append_flags_type_field (flags_type, 31, 2, field_type, "invalid");
	    }

	(You can test this by registering it as a selftest using
	selftests::register_test_foreach_arc and running.)

	Change the assertion to verify that the end bit is within the range of
	the underlying type.  This implicitly verifies that nr_bits is not
	too big as well, so we don't need a separate assertion for that.

	obsd-nat: Report both thread and PID in ::pid_to_str.
	This improves the output of info threads when debugging multiple
	inferiors (e.g. after a fork with detach_on_fork disabled).

2021-07-29  John Baldwin  <jhb@FreeBSD.org>

	obsd-nat: Various fixes for fork following.
	- Don't use #ifdef's on ptrace ops.  obsd-nat.h didn't include
	  <sys/ptrace.h>, so the virtual methods weren't always overridden
	  causing the fork following to not work.  In addition, the thread and
	  fork code is intertwined in ::wait and and the lack of #ifdef's
	  there already assumed both were present.  Finally, both of these
	  ptrace ops have been present in OpenBSD for at least 10 years.

	- Move duplicated code to enable PTRACE_FORK event reporting to a
	  single function and invoke it on new child processes reported via
	  PTRACE_FORK.

	- Don't return early from PTRACE_FORK handling, but instead reset
	  wptid to the correct ptid if the child reports its event before the
	  parent.  This allows the ptid fixup code to add thread IDs if the
	  first event for a process is a PTRACE_FORK event.  This also
	  properly returns ptid's with thread IDs when reporting PTRACE_FORK
	  events.

	- Handle detach_fork by skipping the PT_DETACH.

2021-07-29  John Baldwin  <jhb@FreeBSD.org>

	obsd-nat: Various fixes to obsd_nat_target::wait.
	- Call inf_ptrace_target::wait instead of duplicating the code.
	  Replace a check for WIFSTOPPED on the returned status from waitpid
	  by checking for TARGET_WAITKIND_STOPPED in the parsed status as is
	  done in fbsd_nat_target::wait.

	- Don't use inferior_ptid when deciding if a new process is a child vs
	  parent of the fork.  Instead, use find_inferior_pid and assume that
	  if an inferior already exists, the pid in question is the parent;
	  otherwise, the pid is the child.

	- Don't use inferior_ptid when deciding if the ptid of the process
	  needs to be updated with an LWP ID, or if this is a new thread.
	  Instead, use the approach from fbsd-nat which is to check if a ptid
	  without an LWP exists and if so update the ptid of that thread
	  instead of adding a new thread.

	On BSDs, get_status is set in _initialize_x86_bsd_nat, but only if
	HAVE_PT_GETDBREGS is defined.  PT_GETDBREGS doesn't exist on OpenBSD, so
	get_status (and the other fields of x86_dr_low) are left as nullptr.

	OpenBSD doesn't support getting or setting the x86 debug registers, so
	fix by omitting debug register support entirely on OpenBSD:

	- Change x86bsd_nat_target to only inherit from x86_nat_target if
	  PT_GETDBREGS is supported.

	- Don't include x86-nat.o and nat/x86-dregs.o for OpenBSD/amd64.  They
	  were already omitted for OpenBSD/i386.

	Fix for gdb.tui/tui-layout-asm.exp
	The width of the window is too narrow to display the entire assembly line.
	The width of the columns in the window changes as the test walks thru the
	terminal window output.  The column change results in the first and second
	reads of the same line to differ thus causing the test to fail.  Increasing
	the width of the window keeps the column width consistent thru the test.

	If the test fails, the added check prints an message to the log file if
	the failure may be due to the window being too narrow.

	gdb: clean up some things in features/Makefile
	Clean up some things I noticed:

	 - we generate a regformats/microblaze-with-stack-protect.dat file.  I
	   don't think this is used.  It could be used by a GDBserver built for
	   Microblaze, but GDBserver isn't ported to Microblaze.  So I don't
	   think that's used at all.  Remove the entry in features/Makefile and
	   the file itself.

	 - There are a bunch of *-expedite values in features/Makefile for
	   architectures for which we don't generate dat files.  AFAIK, these
	   *-expedite values are only used when generating dat files.  Remove
	   those that are not necessary.

	 - 32bit-segments.xml is not listed in the Makfile, but it's used.  This
	   means that it wouldn't get re-generated if we were to change how C
	   files are generated from the XML.  It looks like it was simply

	gdb: fix missing space in some info variables output
	Fixes PR gdb/28121.  When a user declares an array like this:

	  int * const foo_1[3];

	And in GDB the user does this:

	  (gdb) info variables foo
	  All variables matching regular expression "foo":

	  File test.c:
	  1:	int * constfoo_1[3];

	Notice the missing space between 'const' and 'foo_1'.  This is fixed
	in c_type_print_varspec_prefix (c-typeprint.c) by passing through the
	flag that indicates if a trailing space is needed, rather than hard
	coding the flag to false as we currently do.

	[gdb/symtab] Fix unhandled dwarf expression opcode with gcc-11 -gdwarf-5
	[ I've confused things by forgetting to add -gdwarf-4 in $subject of
	commit 0057a7ee0d9 "[gdb/testsuite] Add KFAILs for gdb.ada FAILs with
	gcc-11".  So I'm adding here -gdwarf-5 in $subject, even though -gdwarf-5 is
	the default for gcc-11.  I keep getting confused because of working with a
	system gcc-11 compiler that was patched to switch the default back to
	-gdwarf-4. ]

	When running test-case gdb.ada/arrayptr.exp with gcc-11 (and default
	-gdwarf-5), I run into:
	...
	(gdb) print pa_ptr.all^M
	Unhandled dwarf expression opcode 0xff^M
	(gdb) FAIL: gdb.ada/arrayptr.exp: scenario=all: print pa_ptr.all
	...

	What happens is that pa_ptr:
	...
	 <2><1523>: Abbrev Number: 3 (DW_TAG_variable)
	    <1524>   DW_AT_name        : pa_ptr
	    <1529>   DW_AT_type        : <0x14fa>
	...
	has type:
	...
	 <2><14fa>: Abbrev Number: 2 (DW_TAG_typedef)
	    <14fb>   DW_AT_name        : foo__packed_array_ptr
	    <1500>   DW_AT_type        : <0x1504>
	 <2><1504>: Abbrev Number: 4 (DW_TAG_pointer_type)
	    <1505>   DW_AT_byte_size   : 8
	    <1505>   DW_AT_type        : <0x1509>
	...
	which is a pointer to a subrange:
	...
	 <2><1509>: Abbrev Number: 12 (DW_TAG_subrange_type)
	    <150a>   DW_AT_lower_bound : 0
	    <150b>   DW_AT_upper_bound : 0x3fffffffffffffffff
	    <151b>   DW_AT_name        : foo__packed_array
	    <151f>   DW_AT_type        : <0x15cc>
	    <1523>   DW_AT_artificial  : 1
	 <1><15cc>: Abbrev Number: 5 (DW_TAG_base_type)
	    <15cd>   DW_AT_byte_size   : 16
	    <15ce>   DW_AT_encoding    : 7      (unsigned)
	    <15cf>   DW_AT_name        : long_long_long_unsigned
	    <15d3>   DW_AT_artificial  : 1
	...
	with upper bound of form DW_FORM_data16.

	In gdb/dwarf/attribute.h we have:
	...
	  /* Return non-zero if ATTR's value falls in the 'constant' class, or
	     zero otherwise.  When this function returns true, you can apply
	     the constant_value method to it.
	     ...
	     DW_FORM_data16 is not considered as constant_value cannot handle
	     that.  */
	  bool form_is_constant () const;
	...
	so instead we have attribute::form_is_block (DW_FORM_data16) == true.

	Then in attr_to_dynamic_prop for the upper bound, we get a PROC_LOCEXPR
	instead of a PROP_CONST and end up trying to evaluate the constant
	0x3fffffffffffffffff as if it were a locexpr, which causes the
	"Unhandled dwarf expression opcode 0xff".

	In contrast, with -gdwarf-4 we have:
	...
	    <164c>   DW_AT_upper_bound : 18 byte block: \
	      9e 10 ff ff ff ff ff ff ff ff 3f 0 0 0 0 0 0 0 \
	      (DW_OP_implicit_value 16 byte block: \
	        ff ff ff ff ff ff ff ff 3f 0 0 0 0 0 0 0 )
	...

	Fix the dwarf error by translating the DW_FORM_data16 constant into a
	PROC_LOCEXPR, effectively by prepending 0x9e 0x10, such that we have same
	result as with -gdwarf-4:
	...
	(gdb) print pa_ptr.all^M
	That operation is not available on integers of more than 8 bytes.^M
	(gdb) KFAIL: gdb.ada/arrayptr.exp: scenario=all: print pa_ptr.all \
	  (PRMS: gdb/20991)
	...

	PowerPC: ignore sticky options for .machine
	PowerPC gas and objdump for a long time have allowed certain -m/-M
	options that extend a base cpu with extra functional units to be
	specified before the base cpu.  For example, "-maltivec -mpower4" is
	the same as "-mpower4 -maltivec".  See
	https://sourceware.org/pipermail/binutils/2008-January/054935.html

	It doesn't make as much sense that .machine keep any of these
	"sticky" flags when handling a new base cpu.  See gcc PR101393.  I
	think that instead .machine ought to override the command line.
	That's what this patch does.  It is still possible to extend cpu
	functionality with .machine.  For example the following can be
	assembled when selecting a basic -mppc on the command line:
		.machine power5
		.machine altivec
		frin 1,2
		lvsr 3,4,5
	Here, ".machine altivec" extends the ".machine power5" so that both
	the power5 "frin" instruction and the altivec "lvsr" instruction are
	enabled.  Swapping the two ".machine" directives would result in
	failure to assemble "lvsr".

	This change will expose some assembly errors, such as the one in
	glibc/sysdeps/powerpc/powerpc64/tst-ucontext-ppc64-vscr.c, a file
	compiled with -maltivec but containing
	  asm volatile (".machine push;\n"
			".machine \"power5\";\n"
			"vspltisb %0,0;\n"
			"vspltisb %1,-1;\n"
			"vpkuwus %0,%0,%1;\n"
			"mfvscr %0;\n"
			"stvx %0,0,%2;\n"
			".machine pop;"
			: "=v" (v0), "=v" (v1)
			: "r" (vscr_ptr)
			: "memory");
	It's just wrong to choose power5 for a bunch of altivec instructions
	and in fact all of those .machine directives are unnecessary.

		* config/tc-ppc.c (ppc_machine): Don't use command line
		sticky options.

	gdb: remove VALUE_FRAME_ID and fix another frame debug issue
	This commit was originally part of this patch series:

	  (v1): https://sourceware.org/pipermail/gdb-patches/2021-May/179357.html
	  (v2): https://sourceware.org/pipermail/gdb-patches/2021-June/180208.html
	  (v3): https://sourceware.org/pipermail/gdb-patches/2021-July/181028.html

	However, that series is being held up in review, so I wanted to break
	out some of the non-related fixes in order to get these merged.

	This commit addresses two semi-related issues, both of which are
	problems exposed by using 'set debug frame on'.

	The first issue is in frame.c in get_prev_frame_always_1, and was
	introduced by this commit:

	  commit a05a883fbaba69d0f80806e46a9457727fcbe74c
	  Date:   Tue Jun 29 12:03:50 2021 -0400

	      gdb: introduce frame_debug_printf

	This commit replaced fprint_frame with frame_info::to_string.
	However, the former could handle taking a nullptr while the later, a
	member function, obviously requires a non-nullptr in order to make the
	function call.  In one place we are not-guaranteed to have a
	non-nullptr, and so, there is the possibility of triggering undefined
	behaviour.

	The second issue addressed in this commit has existed for a while in
	GDB, and would cause this assertion:

	  gdb/frame.c:622: internal-error: frame_id get_frame_id(frame_info*): Assertion `fi->this_id.p != frame_id_status::COMPUTING' failed.

	We attempt to get the frame_id for a frame while we are computing the
	frame_id for that same frame.

	What happens is that when GDB stops we create a frame_info object for
	the sentinel frame (frame #-1) and then we attempt to unwind this
	frame to create a frame_info object for frame #0.

	In the test case used here to expose the issue we have created a
	Python frame unwinder.  In the Python unwinder we attemt to read the
	program counter register.

	Reading this register will initially create a lazy register value.
	The frame-id stored in the lazy register value will be for the
	sentinel frame (lazy register values hold the frame-id for the frame
	from which the register will be unwound).

	However, the Python unwinder does actually want to examine the value
	of the program counter, and so the lazy register value is resolved
	into a non-lazy value.  This sends GDB into value_fetch_lazy_register
	in value.c.

	Now, inside this function, if 'set debug frame on' is in effect, then
	we want to print something like:

	  frame=%d, regnum=%d(%s), ....

	Where 'frame=%d' will be the relative frame level of the frame for
	which the register is being fetched, so, in this case we would expect
	to see 'frame=0', i.e. we are reading a register as it would be in
	frame #0.  But, remember, the lazy register value actually holds the
	frame-id for frame #-1 (the sentinel frame).

	So, to get the frame_info for frame #0 we used to call:

	  frame = frame_find_by_id (VALUE_FRAME_ID (val));

	Where VALUE_FRAME_ID is:

	  #define VALUE_FRAME_ID(val) (get_prev_frame_id_by_id (VALUE_NEXT_FRAME_ID (val)))

	That is, we start with the frame-id for the next frame as obtained by
	VALUE_NEXT_FRAME_ID, then call get_prev_frame_id_by_id to get the
	frame-id of the previous frame.

	The get_prev_frame_id_by_id function finds the frame_info for the
	given frame-id (in this case frame #-1), calls get_prev_frame to get
	the previous frame, and then calls get_frame_id.

	The problem here is that calling get_frame_id requires that we know
	the frame unwinder, so then have to try each frame unwinder in turn,
	which would include the Python unwinder.... which is where we started,
	and thus we have a loop!

	To prevent this loop GDB has an assertion in place, which is what
	actually triggers.

	Solving the assertion failure is pretty easy, if we consider the code
	in value_fetch_lazy_register and get_prev_frame_id_by_id then what we
	do is:

	  1. Start with a frame_id taken from a value,
	  2. Lookup the corresponding frame,
	  3. Find the previous frame,
	  4. Get the frame_id for that frame, and
	  5. Lookup the corresponding frame
	  6. Print the frame's level

	Notice that steps 3 and 5 give us the exact same result, step 4 is
	just wasted effort.  We could shorten this process such that we drop
	steps 4 and 5, thus:

	  1. Start with a frame_id taken from a value,
	  2. Lookup the corresponding frame,
	  3. Find the previous frame,
	  6. Print the frame's level

	This will give the exact same frame as a result, and this is what I
	have done in this patch by removing the use of VALUE_FRAME_ID from
	value_fetch_lazy_register.

	Out of curiosity I looked to see how widely VALUE_FRAME_ID was used,
	and saw it was only used in one other place in valops.c:value_assign,
	where, once again, we take the result of VALUE_FRAME_ID and pass it to
	frame_find_by_id, thus introducing a redundant frame_id lookup.

	I don't think the value_assign case risks triggering the assertion
	though, as we are unlikely to call value_assign while computing the
	frame_id for a frame, however, we could make value_assign slightly
	more efficient, with no real additional complexity, by removing the
	use of VALUE_FRAME_ID.

	So, in this commit, I completely remove VALUE_FRAME_ID, and replace it
	with a use of VALUE_NEXT_FRAME_ID, followed by a direct call to
	get_prev_frame_always, this should make no difference in either case,
	and resolves the assertion issue from value.c.

	As I said, this patch was originally part of another series, the
	original test relied on the fixes in that original series.  However, I
	was able to create an alternative test for this issue by enabling
	frame debug within an existing test script.

	This commit probably fixes bug PR gdb/27938, though the bug doesn't
	have a reproducer attached so it is not possible to know for sure.

	gdb: Fix numerical field extraction for target description "flags"
	The "val_print_type_code_flags ()" function is responsible for
	extraction of fields for "flags" data type.  These data types are
	used when describing a custom register type in a target description
	XML.  The logic used for the extraction though is not sound:

	    unsigned field_len = TYPE_FIELD_BITSIZE (type, field);
	    ULONGEST field_val
	      = val >> (TYPE_FIELD_BITPOS (type, field) - field_len + 1);

	TYPE_FIELD_BITSIZE: The bit length of the field to be extracted.
	TYPE_FIELD_BITPOS:  The starting position of the field; 0 is LSB.
	val:                The register value.

	Imagine you have a field that starts at position 1 and its length
	is 4 bits.  According to the third line of the code snippet the
	shifting right would become "val >> -2", or "val >> 0xfff...fe"
	to be precise.  That will result in a "field_val" of 0.

	The correct extraction should be:

	    ULONGEST field_val = val >> TYPE_FIELD_BITPOS (type, field);

	The rest of the algorithm that masks out the higher bits is OK.

	gdb: move remaining ChangeLogs to legacy files
	In commit:

	  Date:   Sat Jul 3 16:29:08 2021 -0700

	      Rename gdb/ChangeLog to gdb/ChangeLog-2021

	The gdb/ChangeLog file was renamed, but all of the other ChangeLog
	files relating to gdb were left in place.

	As I understand things, the no ChangeLogs policy applies to all the
	GDB related directories, so this commit renames all of the remaining
	GDB related ChangeLog files.

	As with the original commit, the intention behind this commit is to
	hopefully stop people merging ChangeLog entries by mistake.

	The renames carried out in this commit are:

	    gdb/doc/ChangeLog -> gdb/doc/ChangeLog-1991-2021
	    gdb/stubs/ChangeLog -> gdb/stubs/ChangeLog-2012-2020

	gdb/mi: handle no condition argument case for -break-condition
	As reported in PR gdb/28076 [1], passing no condition argument to the
	-break-condition command (e.g.: "-break-condition 2") should clear the
	condition for breakpoint 2, just like CLI's "condition 2", but instead
	an error message is returned:

	  ^error,msg="-break-condition: Missing the <number> and/or <expr> argument"

	The current implementation of the -break-condition command's argument
	handling (79aabb7308c "gdb/mi: add a '--force' flag to the
	'-break-condition' command") was done according to the documentation,
	where the condition argument seemed mandatory.  However, the
	-break-condition command originally (i.e. before the 79aabb7308c
	patch) used the CLI's "cond" command, and back then not passing a
	condition argument was clearing out the condition.  So, this is a
	regression in terms of the behavior.

	Fix the argument handling of the -break-condition command to allow not
	having a condition argument, and also update the document to make the
	behavior clear.  Also add test cases to test the scenarios which were
	previously not covered.

	gdb/testsuite: test get/set value of unregistered Guile parameter
	When creating a parameter in Guile, you have to create it using
	make-parameter and then register it with GDB with register-parameter!.
	In between, it's still possible (though not documented) to set the
	parameter's value.  I broke this use case by mistake while writing this
	series, so thought it would be good to have a test for it.

	I suppose that people could use this "feature" to give their parameter
	an initial value, even though make-parameter has an initial-value
	parameter for this.  Nevertheless, changing this behavior could break
	some scripts, which is why I think it's important for it to be tested.

	gdb: remove cmd_list_element::function::sfunc
	I don't understand what the sfunc function type in
	cmd_list_element::function is for.  Compared to cmd_simple_func_ftype,
	it has an extra cmd_list_element parameter, giving the callback access
	to the cmd_list_element for the command being invoked.  This allows
	registering the same callback with many commands, and alter the behavior
	using the cmd_list_element's context.

	From the comment in cmd_list_element, it sounds like at some point it
	was the callback function type for set and show functions, hence the
	"s".  But nowadays, it's used for many more commands that need to access
	the cmd_list_element object (see add_catch_command for example).

	I don't really see the point of having sfunc at all, since do_sfunc is
	just a trivial shim that changes the order of the arguments.  All
	commands using sfunc could just as well set cmd_list_element::func to
	their callback directly.

	Therefore, remove the sfunc field in cmd_list_element and everything
	that goes with it.  Rename cmd_const_sfunc_ftype to cmd_func_ftype and
	use it for cmd_list_element::func, as well as for the add_setshow
	commands.

	gdb: rename cfunc to simple_func
	After browsing the CLI code for quite a while and trying really hard, I
	reached the conclusion that I can't give a meaningful explanation of
	what "sfunc" and "cfunc" functions are, in cmd_list_element.  I don't
	see a logic at all.  That makes it very difficult to do any kind of
	change.  Unless somebody can make sense out of all that, I'd like to try
	to retro-fit some logic in the cmd_list_element callback function code
	so that we can understand what is going on, do some cleanups and add new
	features.

	The first change is about "cfunc".  I can't figure out what the "c" in
	cfunc means.  It's not const, because there's already "const" in
	"cmd_const_cfunc_ftype", and the previous "cmd_cfunc_ftype" had nothing
	const..  It's not "cmd" or "command", because there's already "cmd" in
	"cmd_const_cfunc_ftype".

	The "main" command callback, cmd_list_element::func, has three
	parameters, whereas cfunc has two.  It is missing the cmd_list_element
	parameter.  So the only reason I see for cfunc to exist is to be a shim
	between the three and two parameter versions.  Most commands don't need
	to receive the cmd_list_element object, so adding it everywhere would be
	long and would just add more unnecessary boilerplate.  So since this is
	the "simple" version of the callback, compared to the "full", I suggest
	renaming cmd_const_cfunc_ftype into cmd_simple_func_ftype, as well as
	everything (like the utility functions) that goes with it.

	gdb: make inferior::m_args an std::string
	With the current code, both a NULL pointer and an empty string can mean
	"no arguments".  We don't need this distinction.  Changing to a string
	has the advantage that there is now a single state for that (an empty
	string), which makes the code a bit simpler in my opinion.

2021-07-23  Simon Marchi  <simon.marchi@polymtl.ca>

	gdb: remove inferior::{argc,argv}
	There are currently two states that the inferior args can be stored.
	The main one is the `args` field, where they are stored as a single
	string.  The other one is the `argc`/`argv` fields.

	This last one is only used for arguments passed in GDB's
	command line.  And the only outcome is that when get_inferior_args is
	called, `argc`/`argv` are serialized into `args`.  So really,
	`argc`/`argv` is just a staging area before moving the arguments in
	`args`.

	Simplify this by only keeping the `args` field.  Change
	set_inferior_args_vector to immediately serialize the arguments into
	`args`, work that would be done in get_inferior_args later anyway.

	The only time where this work would be "wasted" is when the user passes
	some arguments on the command line, but does not end up running the
	program.  But that just seems unlikely.  And it's not that much work.

	gdb: un-share set_inferior_cwd declaration
	The declaration of set_inferior_cwd is currently shared between gdb and
	gdbserver, in gdbsupport/common-inferior.h.  It doesn't need to be, as
	set_inferior_cwd is not called from common code.  Only get_inferior_cwd
	needs to.

	The motivation for this is that a future patch will change the prototype
	of set_inferior_cwd in gdb, and I don't want to change it for gdbserver
	unnecessarily.  I see this as a good cleanup in any case, to reduce to
	just the essential what is shared between GDB and GDBserver.

	gdb/testsuite: don't error when trying to unset last_spawn_tty_name
	In spawn_capture_tty_name (lib/gdb.exp) we either set or unset
	last_spawn_tty_name depending on whether spawn_out(slave,name) exists
	or not.

	One situation that might cause spawn_out(slave,name) to not exists is
	if the spawn function is called with the argument -leaveopen, which is
	how it is called when processes are created as part of a pipeline, the
	created process has no tty, instead its output is written to a file
	descriptor.

	If a pipeline is created consisting of multiple processes then there
	will be multiple sequential calls to spawn, all using -leaveopen.  The
	first of these calls is fine, spawn_out(slave,name) is not set, and so
	in spawn_capture_tty_name we unset last_spawn_tty_name.  However, on
	the second call to spawn, spawn_out(slave,name) is still not set and
	so in spawn_capture_tty_name we again try to unset
	last_spawn_tty_name, this now throws an error (as last_spawn_tty_name
	is already unset).

	Fix this issue by using -nocomplain with the call to unset in
	spawn_capture_tty_name.

	Before this commit I was seeing gdb.base/gnu-debugdata.exp report 1
	pass, and 1 unsupported test.  After this commit I now see 16 passes
	from this test script.

	I have also improved the code that used to do this:

	    if { [info exists spawn_out] } {
		set ::last_spawn_tty_name $spawn_out(slave,name)
	    } else {
	        ...
	    }

	The problem here is that we check for the existence of spawn_out, and
	then unconditionally read spawn_out(slave,name).  A situation could
	arise where some other element of spawn_out is set,
	e.g. spawn_out(foo), in which case we would enter the if block and try
	to read a non-existent variable.  After this commit we now check
	specifically for spawn_out(slave,name).

	Finally, it is worth noting that before this issue was fixed runtest
	itself, or rather the expect process behind runtest, would segfault
	while exiting.  I haven't looked at all into what the problem is here
	that caused expect to crash, as fixing the bug in GDB's testing
	scripts made the segfault go away.

	input isn't being honored there either. Obviously the 0FC5 encodings of
	{,V}PEXTRW then also need adjustment for consistency reasons.

	x86: drop vex_scalar_w_dq_mode
	It has only a single use and can easily be represented by dq_mode
	instead. Plus its handling in intel_operand_size() was duplicating
	that of vex_vsib_{d,q}_w_dq_mode anyway.

	x86: drop xmm_m{b,w,d,q}_mode
	They're effectively redundant with {b,w,d,q}_mode.

	x86: fold duplicate vector register printing code
	The bulk of OP_XMM() can be easily reused also for OP_EX(). Break the
	shared logic out of the function, and invoke the new helper from both
	places.

	x86: drop vex_mode and vex_scalar_mode
	These are fully redundant with, respectively, x_mode and scalar_mode.

	x86: correct EVEX.V' handling outside of 64-bit mode
	Unlike the high bit of VEX.vvvv / EVEX.vvvv, EVEX.V' is not ignored
	outside of 64-bit mode. Oddly enough there already are tests for these
	cases, but their expectations were wrong. (This may have been based on
	an old SDM version, where the restriction wasn't properly spelled out.)

	x86: fold duplicate code in MOVSXD_Fixup()
	There's no need to have two paths printing the "xd" mnemonic suffix.

	x86: fold duplicate register printing code
	What so far was OP_E_register() can be easily reused also for OP_G().
	Add suitable parameters to the function and move the invocation of
	swap_operand() to OP_E(). Adjust MOVSXD's first operand: There never was
	a need to use movsxd_mode there, and its use gets in the way of the code
	folding.

	x86-64: properly bounds-check %bnd<N> in OP_G()
	The restriction to %bnd0-%bnd3 requires to also check REX.R is clear,
	just like OP_E_Register() also includes REX.B in its check.

	x86-64: generalize OP_G()'s EVEX.R' handling
	EVEX.R' is invalid to be clear not only for mask registers, but also for
	GPRs - IOW everything handled in this function.

2021-07-22  Jan Beulich  <jbeulich@suse.com>

	x86: correct VCVT{,U}SI2SD rounding mode handling
	With EVEX.W clear the instruction doesn't ignore the rounding mode, but
	(like for other insns without rounding semantics) EVEX.b set causes #UD.
	Hence the handling of EVEX.W needs to be done when processing
	evex_rounding_64_mode, not at the decode stages.

	Derive a new 64-bit testcase from the 32-bit one to cover the different
	EVEX.W treatment in both cases.

	x86: drop OP_Mask()
	By moving its vex.r check there it becomes fully redundant with OP_G().

	[gdb/testsuite] Fix gdb.cp/step-and-next-inline.exp with gcc-11
	When running test-case gdb.cp/step-and-next-inline.exp with gcc-11, I run

	...

	[ Note that I get the same result with gcc-11 and target board
	unix/gdb:debug_flags=-gdwarf-4, so this is not a dwarf 4 vs 5 issue. ]

	With gcc-10, I have this trace:

	The test-case tries to verify that we don't step into inlined function
	tree_check (lines 40-43) (so, with the clang trace we get that right).

	The test-case then tries to kfail the problems when using gcc, but this is
	done in such a way that the testing still gets out of sync after a failure.
	That is: the "next step 2" check that is supposed to match
	"TREE_TYPE (t).z != 2" is actually matching "TREE_TYPE (t).z != 1":
	...

	as_bad_subtract
	Many places report errors of the nature "can't resolve a - b".
	This provides a utility function to report such errors consistently.
	I removed the section reporting and quotes around symbol names while I
	was at it.  Compare
	ifunc-2.s:4: Error: can't resolve `bar1' {.text.1 section} - `foo1' {.text.1 section}
	with
	ifunc-2.s:4: Error: can't resolve bar1 - foo1

	In many cases the section names don't help the user very much in
	figuring out what went wrong, and the quotes if present arguably ought
	to be placed around the entire expression:
	can't resolve `bar1 - foo1'

	Remove `netbsdpe` support
	netbsdpe was deprecated in c2ce831330e10dab4703094491f80b6b9a5c2289.
	Since then, a release has passed (2.37), and it was marked obselete in
	5c9cbf07f3f972ecffe13d858010b3179df17b32. Unless I am mistaken, that
	means we can now remove support altogether.

	All branches in the "active" code are remove, and the target is
	additionally marked as obsolete next to the other removed ones for
	libbfd and gdb.

	Per [1] from the NetBSD toolchain list, PE/COFF support was removed a
	decade ago. Furthermore, the sole mention of this target in the binutils
	commit history was in 2002. Together, I'm led to believe this target
	hasn't seen much attention in quite a while.

	Fix printing of non-address types when memory tagging is enabled
	When the architecture supports memory tagging, we handle
	pointer/reference types in a special way, so we can validate tags and
	show mismatches.

	Unfortunately, the currently implementation errors out when the user
	prints non-address values: composite types, floats, references, member
	functions and other things.

	Vector registers:

	 (gdb) p $v0
	 Value can't be converted to integer.

	Non-existent internal variables:

	 (gdb) p $foo
	 Value can't be converted to integer.

	The same happens for complex types and printing struct/union types.

	There are a few problems here.

	The first one is that after print_command_1 evaluates the expression
	to print, the tag validation code call value_as_address
	unconditionally, without making sure we have have a suitable type
	where it makes to sense to call it.  That results in value_as_address
	(if it isn't given a pointer-like type) trying to treat the value as
	an integer and convert it to an address, which #1 - doesn't make sense
	(i.e., no sense in validating tags after "print 1"), and throws for
	non-integer-convertible types.  We fix this by making sure we have a
	pointer or reference type first, and only if so then proceed to check
	if the address-like value has tags.

	The second is that we're calling value_as_address even if we have an
	optimized out or unavailable value, which throws, because the value's
	contents aren't fully accessible/readable.  This error currently
	escapes out and aborts the print.  This case is fixed by checking for
	optimized out / unavailable explicitly.

	Third, the tag checking process does not gracefully handle exceptions.
	If any exception is thrown from the tag validation code, we abort the
	print.  E.g., the target may fail to access tags via a running thread.
	Or the needed /proc files aren't available.  Or some other untold
	reason.  This is a bit too rigid.  This commit changes print_command_1
	to catch errors, print them, and still continue with the normal
	expression printing path instead of erroring out and printing nothing
	useful.

	With this patch, printing works correctly again:

	 (gdb) p $v0

	support.  This is because GDB then makes use BTS instead of PT, so
	exercises different code paths.

	I think that the commit above just exposed an existing problem.  The
	stack trace of the internal error is:

	At frame 45, the new_thread observable is fired.  At this moment, the
	new thread isn't the current thread, inferior_ptid is null_ptid.  I
	think this is ok: the new_thread observable doesn't give any guarantee
	on the global context when observers are invoked.  Frame 35,
	btrace_compute_ftrace_bts, calls gdb_insn_length.  gdb_insn_length
	doesn't have a thread_info or other parameter what could indicate where
	to read memory from, it implicitly uses the global context
	(inferior_ptid).

	So we reach the all_non_exited_threads_range in
	record_btrace_target::record_is_replaying with a null inferior_ptid.
	The previous implemention of all_non_exited_threads_range didn't care,
	but the new one does.  The problem of calling gdb_insn_length and
	ultimately trying to read memory with a null inferior_ptid already
	existed, but the commit mentioned above made it visible.

	Something between frames 40 (record_btrace_enable_warn) and 35
	(btrace_compute_ftrace_bts) needs to be switching the global context to
	make TP the current thread.  Since btrace_compute_ftrace_bts takes the
	thread_info to work with as a parameter, that typically means that it
	doesn't require its caller to also set the global current context
	(current thread) when calling.  If it needs to call other functions
	that do require the global current thread to be set, then it needs to
	temporarily change the current thread while calling these other
	functions.  Therefore, switch and restore the current thread in
	btrace_compute_ftrace_bts.

	By inspection, it looks like btrace_compute_ftrace_pt may also call
	functions sensitive to the global context: it installs the
	btrace_pt_readmem_callback callback in the PT instruction decoder.  When
	this function gets called, inferior_ptid must be set appropriately.  Add
	a switch and restore in there too.

	gdb: convert nat/x86-dregs.c macros to functions
	I'm debugging why GDB crashes on OpenBSD/amd64, turns out it's because
	x86_dr_low.get_status is nullptr.  It would have been useful to be able
	to break on x86_dr_low_get_status, so I thought it would be a good
	reason to convert these function-like macros into functions.

	Fix file-name handling regression with DWARF index
	When run with the gdb-index or debug-names target boards, dup-psym.exp
	fails.  This came up for me because my new DWARF scanner reuses this
	part of the existing index code, and so it registers as a regression.
	This is PR symtab/25834.

	Looking into this, I found that the DWARF index code here is fairly
	different from the psymtab code.  I don't think there's a deep reason
	for this, and in fact, it seemed to me that the index code could
	simply mimic what the psymtab code already does.

	That is what this patch implements.  The DW_AT_name and DW_AT_comp_dir
	are now stored in the quick file names table.  This may require
	allocating a quick file names table even when DW_AT_stmt_list does not
	exist.  Then, the functions that work with this data are changed to
	use find_source_or_rewrite, just as the psymbol code does.  Finally,
	line_header::file_full_name is removed, as it is no longer needed.

	Currently, the index maintains a hash table of "quick file names".
	The hash table uses a deletion function to free the "real name"
	components when necessary.  There's also a second such function to
	implement the forget_cached_source_info method.

	This bug fix patch will create a quick file name object even when
	there is no DW_AT_stmt_list, meaning that the object won't be entered
	in the hash table.  So, this patch changes the memory management
	approach so that the entries are cleared when the per-BFD object is
	destroyed.  (A dwarf2_per_cu_data destructor is not introduced,

	Check for debug-types in map_symbol_filenames
	map_symbol_filenames can skip type units -- in fact I think it has to,
	due to the assertion at the top of dw2_get_file_names.  This may be a
	regression due to the TU/CU unification patch, I did not check.

	Simplify DWARF file name caching
	The DWARF index file name caching code only records when a line table
	has been read and the reading failed.  However, the code would be
	simpler if it recorded any attempt, which is what this patch
	implements.

	Introduce find_source_or_rewrite
	The final bug fix in this series would duplicate the logic in
	psymtab_to_fullname, so this patch extracts the body of this function
	into a new function.

	Simplify file_and_directory storage management
	file_and_directory carries a std::string in case the compilation
	directory is computed, but a subsequent patch wants to preserve this
	string without also having to maintain the storage for it.  So, this
	patch arranges for the compilation directory string to be stored in
	the per-BFD string bcache instead.

	Pass file_and_directory through DWARF line-decoding code
	This patch removes the redundant "comp_unit" parameter from
	compute_include_file_name, and arranges to pass a file_and_directory
	object from the readers down to this function.  It also changes the
	partial symtab reader to use find_file_and_directory, rather than
	reimplement this functionality by hand.

	Rename and refactor psymtab_include_file_name
	In order to fix an index-related regression, I want to use
	psymtab_include_file_name in the DWARF index file-handling code.  This
	patch renames this function and changes it to no longer require a
	partial symtab to be passed in.  A subsequent patch will further
	refactor this code to remove the redundant parameter (which was always
	there but is now more obvious).

	when we expect to have just one.  The problem is prune_inferiors not
	pruning inferiors.  And this is caused by all_inferiors_safe not
	actually iterating on inferiors.  The current implementation:

	  inline all_inferiors_safe_range
	  all_inferiors_safe ()
	  {
	    return {};
	  }

	default-constructs an all_inferiors_safe_range, which default-constructs
	an all_inferiors_safe_iterator as its m_begin field, which
	default-constructs a all_inferiors_iterator.  A default-constructed
	all_inferiors_iterator is an end iterator, which means we have
	constructed an (end,end) all_inferiors_safe_range.

	We actually need to pass down the list on which we want to iterator
	(that is the inferior_list global), so that all_inferiors_iterator's
	first constructor is chosen.  We also pass nullptr as the proc_target
	filter.  In this case, we don't do any filtering, but if in the future
	all_inferiors_safe needed to allow filtering on process target (like
	all_inferiors does), we could pass down a process target pointer.

	basic_safe_iterator's constructor needs to be changed to allow
	constructing the wrapped iterator with multiple arguments, not just one.

	With this, gdb.threads/fork-plus-threads.exp is passing once again for
	me.

	gdb/testsuite: Declare that riscv*-*-linux* cannot hardware_single_step
	Many tests fail in gdb/testsuite/gdb.base/sigstep.exp on
	riscv64-linux-gnu.  Those tests check that when stepping, if the
	debuggee received a signal it should step inside the signal handler.

	This feature requires hardware support for single stepping (or at least
	kernel support), but none are available on riscv*-linux-gnu hosts, at
	the moment at least.

	This patch adds RISC-V to the list of configurations that does not
	have hardware single step capability, disabling tests relying on such
	feature.

	Tested on riscv64-linux-gnu.

	Fix array stride bug
	Investigation of using the Python API with an Ada program showed that
	an array of dynamic types was not being handled properly.  I tracked
	this down to an oddity of how array strides are handled.

	In gdb, an array stride can be attached to the range type, via the
	range_bounds object.  However, the stride can also be put into the
	array's first field.  From create_range_type_with_stride:

	  else if (bit_stride > 0)
	    TYPE_FIELD_BITSIZE (result_type, 0) = bit_stride;

	It's hard to be sure why this is done, but I would guess a combination
	of historical reasons plus a desire (mentioned in a comment somewhere)
	to avoid modifying the range type.

	This patch fixes the problem by changing type::bit_stride to
	understand this convention.  It also fixes one spot that reproduces
	this logic.

	Regression tested on x86-64 Fedora 32.

	gdb: call post_create_inferior at end of follow_fork_inferior
	GDB doesn't handle well the case of an inferior using the JIT interface
	to register JIT-ed objfiles and forking.  If an inferior registers a
	code object using the JIT interface and then forks, the child process
	conceptually has the same code object loaded, so GDB should look it up
	and learn about it (it currently doesn't).

	To achieve this, I think it would make sense to have the
	inferior_created observable called when an inferior is created due to a
	fork in follow_fork_inferior.  The inferior_created observable is
	currently called both after starting a new inferior and after attaching
	to an inferior, allowing various sub-components to learn about that new
	executing inferior.  We can see handling a fork child just like
	attaching to it, so any work done when attaching should also be done in
	the case of a fork child.

	Instead of just calling the inferior_created observable, this patch
	makes follow_fork_inferior call the whole post_create_inferior function.
	This way, the attach and follow-fork code code paths are more alike.

	Given that post_create_inferior calls solib_create_inferior_hook,
	follow_fork_inferior doesn't need to do it itself, so those calls to
	solib_create_inferior_hook are removed.

	One question you may have: why not just call post_create_inferior at the
	places where solib_create_inferior_hook is currently called, instead of
	after target_follow_fork?

	 - there's something fishy for the second solib_create_inferior_hook
	   call site: at this point we have switched the current program space
	   to the child's, but not the current inferior nor the current thread.
	   So solib_create_inferior_hook (and everything under, including
	   check_for_thread_db, for example) is called with inferior 1 as the
	   current inferior and inferior 2's program space as the current
	   program space.  I think that's wrong, because at this point we are
	   setting up inferior 2, and all that code relies on the current
	   inferior.  We could just add a switch_to_thread call before it to
	   make inferior 2 the current one, but there are other problems (see
	   below).

	 - solib_create_inferior_hook is currently not called on the
	   `follow_child && detach_fork` path.  I think we need to call it,
	   because we still get a new inferior in that case (even though we
	   detach the parent).  If we only call post_create_inferior where
	   solib_create_inferior_hook used to be called, then the JIT
	   subcomponent doesn't get informed about the new inferior, and that
	   introduces a failure in the new gdb.base/jit-elf-fork.exp test.

	 - if we try to put the post_create_inferior just after the
	   switch_to_thread that was originally at line 662, or just before the
	   call to target_follow_fork, we introduce a subtle failure in
	   gdb.threads/fork-thread-pending.exp.  What happens then is that
	   libthread_db gets loaded (somewhere under post_create_inferior)
	   before the linux-nat target learns about the LWPs (which happens in
	   linux_nat_target::follow_fork).  As a result, the ALL_LWPS loop in
	   try_thread_db_load_1 doesn't see the child LWP, and the thread-db
	   target doesn't have the chance to fill in thread_info::priv.  A bit
	   later, when the test does "info threads", and
	   thread_db_target::pid_to_str is called, the thread-db target doesn't
	   recognize the thread as one of its own, and delegates the request to
	   the target below.  Because the pid_to_str output is not the expected
	   one, the test fails.

	   This tells me that we need to call the process target's follow_fork
	   first, to make the process target create the necessary LWP and thread
	   structures.  Then, we can call post_create_inferior to let the other
	   components of GDB do their thing.

	   But then you may ask: check_for_thread_db is already called today,
	   somewhere under solib_create_inferior_hook, and that is before
	   target_follow_fork, why don't we see this ordering problem!?  Well,
	   because of the first bullet point: when check_for_thread_db /
	   thread_db_load are called, the current inferior is (erroneously)
	   inferior 1, the parent.  Because libthread_db is already loaded for
	   the parent, thread_db_load early returns.  check_for_thread_db later
	   gets called by linux_nat_target::follow_fork.  At this point, the
	   current inferior is the correct one and the child's LWP exists, so
	   all is well.

	Since we now call post_create_inferior after target_follow_fork, which
	calls the inferior_created observable, which calls check_for_thread_db,
	I don't think linux_nat_target needs to explicitly call
	check_for_thread_db itself, so that is removed.

	In terms of testing, this patch adds a new gdb.base/jit-elf-fork.exp
	test.  It makes an inferior register a JIT code object and then fork.
	It then verifies that whatever the detach-on-fork and follow-fork-child
	parameters are, GDB knows about the JIT code object in all the inferiors
	that survive the fork.  It verifies that the inferiors can unload that
	code object.

	There isn't currently a way to get visibility into GDB's idea of the JIT
	code objects for each inferior.  For the purpose of this test, add the
	"maintenance info jit" command.  There isn't much we can print about the
	JIT code objects except their load address.  So the output looks a bit
	bare, but it's good enough for the test.

	gas: default TC_VALIDATE_FIX_SUB to 0
	gas/write.c provides a fallback TC_VALIDATE_FIX_SUB define that can be
	a problem for some targets, the problem being that a non-zero
	definition of TC_VALIDATE_FIX_SUB says that some uses of fx_subsy are
	OK, in effect that the target will handle fx_subsy in md_apply_fix
	and/or tc_gen_reloc.  A lot of targets don't have the necessary
	md_apply_fix and tc_gen_reloc support.  So a safer default is to
	disallow fx_subsy by default.

	I've had a good look over target usage of fx_subsy, and think I've
	caught all the cases where targets need TC_VALIDATE_FIX_SUB.  Possible
	failures would be limited to alpha, microblaze, ppc and s390 (the

	(gdb) ERROR: Undefined command "frame apply all -- -".

	Use /bin/sh as shebang in gdb/make-init-c
	While testing the NixOS[1] packaging for gdb-11.0.90.tar.xz, I got the
	following error:

	In the nix build environment, /usr/bin/env is not present, only /bin/sh
	is.  This patch makes sure that gdb/make-init-c uses '/bin/sh' as
	interpreter as this is the only one available on this platform.

	I do not think this change will cause regressions on any other
	configuration.

	arm-fbsd-nat: Use fetch_register_set and store_register_set.

	aarch64-fbsd-nat: Use fetch_register_set and store_register_set.

	riscv-fbsd-nat: Use fetch_register_set and store_register_set.

	fbsd-nat: Add helper functions to fetch and store register sets.
	In particular, this supports register sets described by a regcache_map
	which are fetched and stored with dedicated ptrace operations.  These
	functions are intended to be used in architecture-specific
	fetch_registers and store_registers target methods.

	Add regcache_map_supplies helper routine.
	This helper can be used in the fetch_registers and store_registers
	target methods to determine if a register set includes a specific
	register.

	 #14 0x0000555555ae4730 in objfile::~objfile (this=0x555556515540, __in_chrg=<optimized out>) at src/gdb/objfiles.c:573

	That's a dtor, thus noexcept.  That's the reason for the
	std::terminate.

	The previous patch fixed things such that the exception above isn't
	thrown anymore.  However, it's possible that e.g., the remote
	connection drops just while a user types "nosharedlibrary", or some
	other reason that leads to objfile::~objfile, and then we end up the
	same std::terminate problem.

	Also notice that frames #9-#11 are BFD frames:

	 #9  0x0000555555e09e3f in opncls_bclose (abfd=0x555556bc27e0) at src/bfd/opncls.c:599

	 #11 0x0000555555e0a27a in bfd_close (abfd=0x555556bc27e0) at src/bfd/opncls.c:814

	BFD is written in C and thus throwing exceptions over such frames may
	either not clean up properly, or, may abort if bfd is not compiled
	with -fasynchronous-unwind-tables (x86-64 defaults that on, but not
	all GCC ports do).

	Thus frame #8 seems like a good place to swallow exceptions.  More so
	since in this spot we already ignore target_fileio_close return
	errors.  That's what this commit does.  Without the previous fix, we'd
	see:

	 (gdb) detach
	 Detaching from program: target:/any/program, process 2197701
	 Ending remote debugging.
	 [Inferior 1 (process 2197701) detached]
	 warning: cannot close "target:/lib64/ld-linux-x86-64.so.2": Remote connection closed

	Note it prints a warning, which would still be a regression compared
	to GDB 10, if it weren't for the previous fix.

	 #28 0x00005555559e3f5f in detach_command (args=0x0, from_tty=1) at src/gdb/infcmd.c:2769

	So frame #28 already detached the remote process, and then we're
	purging the shared libraries.  GDB had opened remote shared libraries
	via the target: sysroot, so it tries closing them.  GDBserver is
	tearing down already, so remote communication breaks down and we close
	the remote target and throw TARGET_CLOSE_ERROR.

	Note frame #14:

	 #14 0x0000555555ae4730 in objfile::~objfile (this=0x555556515540, __in_chrg=<optimized out>) at src/gdb/objfiles.c:573

	That's a dtor, thus noexcept.  That's the reason for the
	std::terminate.

	Stepping back a bit, why do we still have open remote files if we've
	managed to detach already, and, we're debugging with "target remote"?
	The reason is that commit 408f66864a1a823591b26420410c982174c239a2
	makes detach_command hold a reference to the target, so the remote
	target won't be finally closed until frame #28 returns.  It's closing
	the target that invalidates target file I/O handles.

	This commit fixes the issue by not relying on target_close to
	invalidate the target file I/O handles, instead invalidate them
	immediately in remote_unpush_target.  So when GDB purges the solibs,
	and we end up in target_fileio_close (frame #7 above), there's nothing
	to do, and we don't try to talk with the remote target anymore.

	The regression isn't seen when testing with
	--target_board=native-gdbserver, because that does "set sysroot" to
	disable the "target:" sysroot, for test run speed reasons.  So this
	commit adds a testcase that explicitly tests detach with "set sysroot
	target:".

	[gdb/testsuite] Fix check-libthread-db.exp FAILs with glibc 2.33
	When running test-case gdb.threads/check-libthread-db.exp on openSUSE
	Tumbleweed with glibc 2.33, I get:
	...
	(gdb) maint check libthread-db^M
	Running libthread_db integrity checks:^M
	  Got thread 0x7ffff7c79b80 => 9354 => 0x7ffff7c79b80; errno = 0 ... OK^M
	libthread_db integrity checks passed.^M
	(gdb) FAIL: gdb.threads/check-libthread-db.exp: user-initiated check: \
	  libpthread.so not initialized (pattern 2)
	...

	The test-case expects instead:
	...
	  Got thread 0x0 => 9354 => 0x0 ... OK^M
	...
	which is what I get on openSUSE Leap 15.2 with glibc 2.26, and what is
	described in the test-case like this:
	...
	    # libthread_db should fake a single thread with th_unique == NULL.
	...

	Using a breakpoint on check_thread_db_callback we can compare the two
	scenarios, and find that in the latter case we hit this code in glibc function
	iterate_thread_list in nptl_db/td_ta_thr_iter.c:
	...
	  if (next == 0 && fake_empty)
	    {
	      /* __pthread_initialize_minimal has not run.  There is just the main
	         thread to return.  We cannot rely on its thread register.  They
	         sometimes contain garbage that would confuse us, left by the
	         kernel at exec.  So if it looks like initialization is incomplete,
	         we only fake a special descriptor for the initial thread.  */
	      td_thrhandle_t th = { ta, 0 };
	      return callback (&th, cbdata_p) != 0 ? TD_DBERR : TD_OK;
	    }
	...
	while in the former case we don't because this preceding statement doesn't
	result in next == 0:
	...
	  err = DB_GET_FIELD (next, ta, head, list_t, next, 0);
	...

	Note that the comment mentions __pthread_initialize_minimal, but in both cases
	it has already run before we hit the callback, so it's possible the comment is
	no longer accurate.

	The change in behaviour bisect to glibc commit 1daccf403b "nptl: Move stack
	list variables into _rtld_global", which moves the initialization of stack
	list variables such as __stack_user to an earlier moment, which explains well
	enough the observed difference.

	Fix this by updating the regexp patterns to agree with what libthread-db is
	telling us.

	Tested on x86_64-linux, both with glibc 2.33 and 2.26.

	gdb: disable commit-resumed on -exec-interrupt --thread-group
	As reported in PR gdb/28077, we hit an internal error when using
	-exec-interrupt with --thread-group:

	    info threads
	    &"info threads\n"
	    ~"  Id   Target Id             Frame \n"

	This is because this code path never disables commit-resumed (a
	requirement for calling target_stop, as documented in
	process_stratum_target::»commit_resumed_state) before calling
	target_stop.

	The other 3 code paths in mi_cmd_exec_interrupt use interrupt_target_1,
	which does it.  But the --thread-group code path uses its own thing
	which doesn't do it.  Fix this by adding a scoped_disable_commit_resumed
	in this code path.

	Calling -exec-interrupt with --thread-group is apparently not tested at
	the moment (which is why this bug could creep in).  Add a new test for
	that.  The test runs two inferiors and tries to interrupt them with
	"-exec-interrupt --thread-group X".

	gdb: optimize all_matching_threads_iterator
	all_matching_threads_iterator is used extensively in some pretty fast
	paths, often under the all_non_exited_threads function.

	If a filter target and thread-specific ptid are given, it iterates on
	all threads of all inferiors of that target, to ultimately yield exactly
	on thread.  And this happens quite often, which means we unnecessarily
	spend time iterating on threads to find the one we are looking for.  The
	same thing happens if an inferior-specific ptid is given, although there
	the iterator yields all the threads of that inferior.

	In those cases, the callers of all_non_exited_threads could have
	different behaviors depending on the kind of ptid, to avoid this
	inefficiency, but that would be very tedious.  Using
	all_non_exited_threads has the advantage that one simple implementation
	can work seamlessly on multiple threads or on one specific thread, just
	by playing with the ptid.

	Instead, optimize all_matching_threads_iterator directly to detect these
	different cases and limiting what we iterate on to just what we need.

	 - if filter_ptid is minus_one_ptid, do as we do now: filter inferiors
	   based on filter_target, iterate on all of the matching inferiors'
	   threads
	 - if filter_ptid is a pid-only ptid (then a filter_target must
	   necessarily be given), look up that inferior and iterate on all its
	   threads
	 - otherwise, filter_ptid is a thread-specific ptid, so look up that
	   specific thread and "iterate" only on it

	For the last case, what was an iteration on all threads of the filter
	target now becomes a call to find_thread_ptid, which is quite efficient
	now thanks to inferior::ptid_thread_map.

	When debugging a large number of threads (thousands), looking up a

	Add inferior::thread_map, an std::unordered_map indexed by ptid_t, and

	gdb: optimize selection of resumed thread with pending event
	Consider a case where many threads (thousands) keep hitting a breakpoint
	whose condition evaluates to false.  random_pending_event_thread is
	responsible for selecting a thread from an inferior among all that are
	resumed with a pending wait status.  It is currently implemented by
	walking the inferior's thread list twice: once to count the number of
	candidates and once to select a random one.

	Since we now maintain a per target list of resumed threads with pending
	event, we can implement this more efficiently by walking that list and
	selecting the first thread that matches the criteria
	(random_pending_event_thread looks for an thread from a specific
	inferior, and possibly a filter ptid).  It will be faster especially in
	the common case where there isn't any resumed thread with pending
	event.  Currently, we have to iterate the thread list to figure this
	out.  With this patch, the list of resumed threads with pending event
	will be empty, so it's quick to figure out.

	The random selection is kept, but is moved to
	process_stratum_target::random_resumed_with_pending_wait_status.  The
	same technique is used: do a first pass to count the number of
	candidates, and do a second pass to select a random one.  But given that
	the list of resumed threads with pending wait statuses will generally be
	short, or at least shorter than the full thread list, it should be
	quicker.

	Note that this isn't completely true, in case there are multiple
	inferiors on the same target.  Imagine that inferior A has 10k resumed
	threads with pending wait statuses, and random_pending_event_thread is
	called with inferior B.  We'll need to go through the list that contains
	inferior A's threads to realize that inferior B has no resumed threads
	with pending wait status.  But I think that this is a corner /
	pathological case.  And a possible fix for this situation would be to
	make random_pending_event_thread work per-process-target, rather than
	per-inferior.

	gdb: optimize check for resumed threads with pending wait status in maybe_set_commit_resumed_all_targets
	Consider a test case where many threads (thousands) keep hitting a

	maybe_set_commit_resumed_all_targets is called at each handled event,
	when the scoped_disable_commit_resumed object in fetch_inferior_event is

	status (in which case, we don't want to commit the resumed threads, as
	we want to consume this status first).  It is currently implemented as
	walking all threads of the target.

	Since we now maintain a per-target list of resumed threads with pending
	status, we can do this check efficiently, by checking whether that list
	is empty or not.

	gdb: maintain per-process-target list of resumed threads with pending wait status
	Looking up threads that are both resumed and have a pending wait
	status to report is something that we do quite often in the fast path
	and is expensive if there are many threads, since it currently requires
	walking whole thread lists.

	The first instance is in maybe_set_commit_resumed_all_targets.  This is
	called after handling each event in fetch_inferior_event, to see if we
	should ask targets to commit their resumed threads or not.  If at least
	one thread is resumed but has a pending wait status, we don't ask the
	targets to commit their resumed threads, because we want to consume and
	handle the pending wait status first.

	The second instance is in random_pending_event_thread, where we want to
	select a random thread among all those that are resumed and have a
	pending wait status.  This is called every time we try to consume
	events, to see if there are any pending events that we we want to
	consume, before asking the targets for more events.

	To allow optimizing these cases, maintain a per-process-target list of
	threads that are resumed and have a pending wait status.

	In maybe_set_commit_resumed_all_targets, we'll be able to check in O(1)
	if there are any such threads simply by checking whether the list is
	empty.

	In random_pending_event_thread, we'll be able to use that list, which
	will be quicker than iterating the list of threads, especially when
	there are no resumed with pending wait status threads.

	About implementation details: using the new setters on class
	thread_info, it's relatively easy to maintain that list.  Any time the
	"resumed" or "pending wait status" property is changed, we check whether
	that should cause the thread to be added or removed from the list.

	In set_thread_exited, we try to remove the thread from the list, because
	keeping an exited thread in that list would make no sense (especially if
	the thread is freed).  My first implementation assumed that a process
	stratum target was always present when set_thread_exited is called.
	That's however, not the case: in some cases, targets unpush themselves
	from an inferior and then call "exit_inferior", which exits all the
	threads.  If the target is unpushed before set_thread_exited is called
	on the threads, it means we could mistakenly leave some threads in the
	list.  I tried to see how hard it would be to make it such that targets
	have to exit all threads before unpushing themselves from the inferior
	(that would seem logical to me, we don't want threads belonging to an
	inferior that has no process target).  That seemed quite difficult and
	not worth the time at the moment.  Instead, I changed
	inferior::unpush_target to remove all threads of that inferior from the
	list.

	As of this patch, the list is not used, this is done in the subsequent
	patches.

	The debug messages in process-stratum-target.c need to print some ptids.
	However, they can't use target_pid_to_str to print them without
	introducing a dependency on the current inferior (the current inferior
	is used to get the current target stack).  For debug messages, I find it
	clearer to print the spelled out ptid anyway (the pid, lwp and tid
	values).  Add a ptid_t::to_string method that returns a string
	representation of the ptid that is meant for debug messages, a bit like
	we already have frame_id::to_string.

	gdb: make thread_info::suspend private, add getters / setters
	A following patch will want to take some action when a pending wait
	status is set on or removed from a thread.  Add a getter and a setter on
	thread_info for the pending waitstatus, so that we can add some code in
	the setter later.

	The thing is, the pending wait status field is in the
	thread_suspend_state, along with other fields that we need to backup
	before and restore after the thread does an inferior function call.
	Therefore, make the thread_suspend_state member private
	(thread_info::suspend becomes thread_info::m_suspend), and add getters /
	setters for all of its fields:

	 - pending wait status
	 - stop signal
	 - stop reason
	 - stop pc

	For the pending wait status, add the additional has_pending_waitstatus
	and clear_pending_waitstatus methods.

	I think this makes the thread_info interface a bit nicer, because we
	now access the fields as:

	  thread->stop_pc ()

	rather than

	  thread->suspend.stop_pc

	The stop_pc field being in the `suspend` structure is an implementation
	detail of thread_info that callers don't need to be aware of.

	For the backup / restore of the thread_suspend_state structure, add
	save_suspend_to and restore_suspend_from methods.  You might wonder why
	`save_suspend_to`, as opposed to a simple getter like

	  thread_suspend_state &suspend ();

	I want to make it clear that this is to be used only for backing up and
	restoring the suspend state, _not_ to access fields like:

	  thread->suspend ()->stop_pc

	Adding some getters / setters allows adding some assertions.  I find
	that this helps understand how things are supposed to work.  Add:

	 - When getting the pending status (pending_waitstatus method), ensure
	   that there is a pending status.
	 - When setting a pending status (set_pending_waitstatus method), ensure
	   there is no pending status.

	There is one case I found where this wasn't true - in
	remote_target::process_initial_stop_replies - which needed adjustments
	to respect that contract.  I think it's because
	process_initial_stop_replies is kind of (ab)using the
	thread_info::suspend::waitstatus to store some statuses temporarily, for
	its internal use (statuses it doesn't intent on leaving pending).

	process_initial_stop_replies pulls out stop replies received during the
	initial connection using target_wait.  It always stores the received
	event in `evthread->suspend.waitstatus`.  But it only sets
	waitstatus_pending_p, if it deems the event interesting enough to leave
	pending, to be reported to the core:

	      if (ws.kind != TARGET_WAITKIND_STOPPED
		  || ws.value.sig != GDB_SIGNAL_0)
		evthread->suspend.waitstatus_pending_p = 1;

	It later uses this flag a bit below, to choose which thread to make the
	"selected" one:

	      if (selected == NULL
		  && thread->suspend.waitstatus_pending_p)
		selected = thread;

	And ultimately that's used if the user-visible mode is all-stop, so that
	we print the stop for that interesting thread:

	  /* In all-stop, we only print the status of one thread, and leave
	     others with their status pending.  */
	  if (!non_stop)
	    {
	      thread_info *thread = selected;
	      if (thread == NULL)
		thread = lowest_stopped;
	      if (thread == NULL)
		thread = first;

	      print_one_stopped_thread (thread);
	    }

	But in any case (all-stop or non-stop), print_one_stopped_thread needs
	to access the waitstatus value of these threads that don't have a
	pending waitstatus (those that had TARGET_WAITKIND_STOPPED +
	GDB_SIGNAL_0).  This doesn't work with the assertions I've
	put.

	So, change the code to only set the thread's wait status if it is an
	interesting one that we are going to leave pending.  If the thread
	stopped due to a non-interesting event (TARGET_WAITKIND_STOPPED +
	GDB_SIGNAL_0), don't store it.  Adjust print_one_stopped_thread to
	understand that if a thread has no pending waitstatus, it's because it
	stopped with TARGET_WAITKIND_STOPPED + GDB_SIGNAL_0.

	The call to set_last_target_status also uses the pending waitstatus.
	However, given that the pending waitstatus for the thread may have been
	cleared in print_one_stopped_thread (and that there might not even be a
	pending waitstatus in the first place, as explained above), it is no
	longer possible to do it at this point.  To fix that, move the call to
	set_last_target_status in print_one_stopped_thread.  I think this will
	preserve the existing behavior, because set_last_target_status is
	currently using the current thread's wait status.  And the current
	thread is the last one for which print_one_stopped_thread is called.  So
	by calling set_last_target_status in print_one_stopped_thread, we'll get
	the same result.  set_last_target_status will possibly be called
	multiple times, but only the last call will matter.  It just means
	possibly more calls to set_last_target_status, but those are cheap.

	The threads that need a step-over are currently linked using an

	For this, we have a use case of appending a list to another one (in

	method.  However, only support splicing the other list at the end of the
	`this` list, since that's all we need.

	Add explicit default assignment operators to
	reference_to_pointer_iterator, which are otherwise implicitly deleted.
	This is needed because to define thread_step_over_list_safe_iterator, we
	wrap reference_to_pointer_iterator inside a basic_safe_iterator, and
	basic_safe_iterator needs to be able to copy-assign the wrapped
	iterator.  The move-assignment operator is therefore not needed, only

	gdb: make inferior_list use intrusive_list
	Change inferior_list, the global list of inferiors, to use
	intrusive_list.  I think most other changes are somewhat obvious
	fallouts from this change.

	There is a small change in behavior in scoped_mock_context.  Before this
	patch, constructing a scoped_mock_context would replace the whole
	inferior list with only the new mock inferior.  Tests using two
	scoped_mock_contexts therefore needed to manually link the two inferiors
	together, as the second scoped_mock_context would bump the first mock
	inferior from the thread list.  With this patch, a scoped_mock_context
	adds its mock inferior to the inferior list on construction, and removes
	it on destruction.  This means that tests run with mock inferiors in the
	inferior list in addition to any pre-existing inferiors (there is always
	at least one).  There is no possible pid clash problem, since each
	scoped mock inferior uses its own process target, and pids are per
	process target.

	gdb: introduce intrusive_list, make thread_info use it
	GDB currently has several objects that are put in a singly linked list,
	by having the object's type have a "next" pointer directly.  For
	example, struct thread_info and struct inferior.  Because these are
	simply-linked lists, and we don't keep track of a "tail" pointer, when
	we want to append a new element on the list, we need to walk the whole
	list to find the current tail.  It would be nice to get rid of that
	walk.  Removing elements from such lists also requires a walk, to find
	the "previous" position relative to the element being removed.  To
	eliminate the need for that walk, we could make those lists
	doubly-linked, by adding a "prev" pointer alongside "next".  It would be
	nice to avoid the boilerplate associated with maintaining such a list
	manually, though.  That is what the new intrusive_list type addresses.

	With an intrusive list, it's also possible to move items out of the
	list without destroying them, which is interesting in our case for
	example for threads, when we exit them, but can't destroy them
	immediately.  We currently keep exited threads on the thread list, but
	we could change that which would simplify some things.

	Note that with std::list, element removal is O(N).  I.e., with
	std::list, we need to walk the list to find the iterator pointing to
	the position to remove.  However, we could store a list iterator
	inside the object as soon as we put the object in the list, to address
	it, because std::list iterators are not invalidated when other
	elements are added/removed.  However, if you need to put the same
	object in more than one list, then std::list<object> doesn't work.
	You need to instead use std::list<object *>, which is less efficient
	for requiring extra memory allocations.  For an example of an object
	in multiple lists, see the step_over_next/step_over_prev fields in
	thread_info:

	  /* Step-over chain.  A thread is in the step-over queue if these are
	     non-NULL.  If only a single thread is in the chain, then these
	     fields point to self.  */
	  struct thread_info *step_over_prev = NULL;
	  struct thread_info *step_over_next = NULL;

	The new intrusive_list type gives us the advantages of an intrusive
	linked list, while avoiding the boilerplate associated with manually
	maintaining it.

	intrusive_list's API follows the standard container interface, and thus
	std::list's interface.  It is based the API of Boost's intrusive list,
	here:

	 https://www.boost.org/doc/libs/1_73_0/doc/html/boost/intrusive/list.html

	Our implementation is relatively simple, while Boost's is complicated
	and intertwined due to a lot of customization options, which our version
	doesn't have.

	The easiest way to use an intrusive_list is to make the list's element
	type inherit from intrusive_node.  This adds a prev/next pointers to
	the element type.  However, to support putting the same object in more
	than one list, intrusive_list supports putting the "node" info as a
	field member, so you can have more than one such nodes, one per list.

	As a first guinea pig, this patch makes the per-inferior thread list use
	intrusive_list using the base class method.

	Unlike Boost's implementation, ours is not a circular list.  An earlier
	version of the patch was circular: the intrusive_list type included an
	intrusive_list_node "head".  In this design, a node contained pointers
	to the previous and next nodes, not the previous and next elements.
	This wasn't great for when debugging GDB with GDB, as it was difficult
	to get from a pointer to the node to a pointer to the element.  With the
	design proposed in this patch, nodes contain pointers to the previous
	and next elements, making it easy to traverse the list by hand and
	inspect each element.

	The intrusive_list object contains pointers to the first and last
	elements of the list.  They are nullptr if the list is empty.
	Each element's node contains a pointer to the previous and next
	elements.  The first element's previous pointer is nullptr and the last
	element's next pointer is nullptr.  Therefore, if there's a single
	element in the list, both its previous and next pointers are nullptr.
	To differentiate such an element from an element that is not linked into
	a list, the previous and next pointers contain a special value (-1) when
	the node is not linked.  This is necessary to be able to reliably tell
	if a given node is currently linked or not.

	A begin() iterator points to the first item in the list.  An end()
	iterator contains nullptr.  This makes iteration until end naturally
	work, as advancing past the last element will make the iterator contain
	nullptr, making it equal to the end iterator.  If the list is empty,
	a begin() iterator will contain nullptr from the start, and therefore be
	immediately equal to the end.

	Iterating on an intrusive_list yields references to objects (e.g.
	`thread_info&`).  The rest of GDB currently expects iterators and ranges
	to yield pointers (e.g. `thread_info*`).  To bridge the gap, add the
	reference_to_pointer_iterator type.  It is used to define
	inf_threads_iterator.

	Add a Python pretty-printer, to help inspecting intrusive lists when
	debugging GDB with GDB.  Here's an example of the output:

	    (top-gdb) p current_inferior_.m_obj.thread_list
	    $1 = intrusive list of thread_info = {0x61700002c000, 0x617000069080, 0x617000069400, 0x61700006d680, 0x61700006eb80}

	It's not possible with current master, but with this patch [1] that I
	hope will be merged eventually, it's possible to index the list and
	access the pretty-printed value's children:

	    (top-gdb) p current_inferior_.m_obj.thread_list[1]
	    $2 = (thread_info *) 0x617000069080
	    (top-gdb) p current_inferior_.m_obj.thread_list[1].ptid
	    $3 = {
	      m_pid = 406499,
	      m_lwp = 406503,
	      m_tid = 0
	    }

	Even though iterating the list in C++ yields references, the Python
	pretty-printer yields pointers.  The reason for this is that the output
	of printing the thread list above would be unreadable, IMO, if each
	thread_info object was printed in-line, since they contain so much
	information.  I think it's more useful to print pointers, and let the
	user drill down as needed.

	PR28069, assertion fail in dwarf.c:display_discr_list
	We shouldn't be asserting on anything to do with leb128 values, or
	reporting file and line numbers when something unexpected happens.
	leb128 data is of indeterminate length, perfect for fuzzer mayhem.
	It would only make sense to assert or report dwarf.c/readelf.c source
	lines if the code had already sized and sanity checked the leb128
	values.

	After removing the assertions, the testcase then gave:

	    <37>   DW_AT_discr_list  : 5 byte block: 0 0 0 0 0 	(label 0, label 0, label 0, label 0, <corrupt>
	readelf: Warning: corrupt discr_list - unrecognized discriminant byte 0x5

	    <3d>   DW_AT_encoding    : 0	(void)
	    <3e>   DW_AT_identifier_case: 0	(case_sensitive)
	    <3f>   DW_AT_virtuality  : 0	(none)
	    <40>   DW_AT_decimal_sign: 5	(trailing separate)

	So the DW_AT_discr_list was showing more data than just the 5 byte
	block.  That happened due to "end" pointing a long way past the end of
	block, and uvalue decrementing past zero on one of the leb128 bytes.

	According to bug 28056, running an s390x binary gives:

	    (gdb) run
	    Starting program: /usr/bin/ls
	    /home/ubuntu/tmp/gdb-11.0.90.20210705/gdb/linux-tdep.c:2550: internal-error: displaced_step_prepare_status linux_displaced_step_prepare(gdbarch*, thread_info*, CORE_ADDR&): Assertion `gdbarch_data->num_disp_step_buffers > 0' failed.

	This is because the s390 architecture registers some Linux-specific
	displaced stepping callbacks in the OS-agnostic s390_gdbarch_init:

	    set_gdbarch_displaced_step_prepare (gdbarch, linux_displaced_step_prepare);
	    set_gdbarch_displaced_step_finish (gdbarch, linux_displaced_step_finish);
	    set_gdbarch_displaced_step_restore_all_in_ptid
	      (gdbarch, linux_displaced_step_restore_all_in_ptid);

	But then the Linux-specific s390_linux_init_abi_any passes
	num_disp_step_buffers=0 to linux_init_abi:

	    linux_init_abi (info, gdbarch, 0);

	The problem happens when linux_displaced_step_prepare is called for the
	first time.  It tries to allocate the displaced stepping buffers, but
	sees that the number of displaced stepping buffers for that architecture
	is 0, which is unexpected / invalid.

	s390_gdbarch_init should not register the linux_* callbacks, that is
	expected to be done by linux_init_abi.  If debugging a bare-metal s390
	program, or an s390 program on another OS GDB doesn't know about, we
	wouldn't want to use them.  We would either register no callbacks, if
	displaced stepping isn't supported, or register a different set of
	callbacks if we wanted to support displaced stepping in those cases.

	The commit that refactored the displaced stepping machinery and
	introduced these set_gdbarch_displaced_step_* calls is 187b041e2514
	("gdb: move displaced stepping logic to gdbarch, allow starting
	concurrent displaced steps").  However, even before that,
	s390_gdbarch_init did:

	  set_gdbarch_displaced_step_location (gdbarch, linux_displaced_step_location);

	... which already seemed wrong.  The Linux-specific callback was used
	even for non-Linux system.  Maybe that was on purpose, because it would
	also happen to work in some other non-Linux case, or maybe it was simply
	a mistake.  I'll assume that this was a small mistake when
	s390-tdep.{h,c} where factored out of s390-linux-tdep.c, in d6e589456475
	("s390: Split up s390-linux-tdep.c into two files").

	Fix this by removing the setting of these displaced step callbacks from
	s390_gdbarch_init.  Instead, pass num_disp_step_buffers=1 to
	linux_init_abi, in s390_linux_init_abi_any.  Doing so will cause
	linux_init_abi to register these same callbacks.  It will also mean that
	when debugging a bare-metal s390 executable or an executable on another
	OS that GDB doesn't know about, gdbarch_displaced_step_prepare won't be
	set, so displaced stepping won't be used.

	This patch will need to be merged in the gdb-11-branch, since this is a
	GDB 11 regression, so here's the ChangeLog entry:

	gdb/ChangeLog:

		* s390-linux-tdep.c (s390_linux_init_abi_any): Pass 1 (number
		of displaced stepping buffers to linux_init_abi.
		* s390-tdep.c (s390_gdbarch_init): Don't set the Linux-specific
		displaced-stepping gdbarch callbacks.

	gdb/Makefile.in: remove testsuite from SUBDIRS
	When distclean-ing a configured / built gdb directory, like so:

	    $ ./configure && make all-gdb && make distclean

	The distclean operation fails with:

	    Missing testsuite/Makefile

	If we look at the SUBDIRS variable in the generated gdb/Makefile,
	testsuite is there twice:

	    SUBDIRS = doc  testsuite data-directory testsuite

	So we try distclean-ing the testsuite directory twice.  The second time,
	gdb/testsuite/Makefile doesn't exist, so it fails.

	The first "testsuite" comes from the @subdirs@ replacement, because of
	the `AC_CONFIG_SUBDIRS` macro in gdb/configure.ac.  The second one is
	hard-coded in gdb/Makefile.in:

	    SUBDIRS = doc @subdirs@ data-directory testsuite

	The hard-coded was added by:

	    bdbbcd577460 ("Always build 'all' in gdb/testsuite")

	which came after `testsuite` was removed from @subdirs@ by:

	    f99d1d37496f ("Remove gdb/testsuite/configure")

	My commit a100a94530eb ("gdb/testsuite: restore configure script")
	should have removed the hard-coded `testsuite`, since it added it back
	as a "subdir", but I missed it because I only looked f99d1d37496f to
	write my patch.

	Fix this by removing the hard-coded one.

	This patch should be pushed to both master and gdb-11-branch, hence the
	ChangeLog entry:

	gdb/ChangeLog:

		* Makefile.in (SUBDIRS): Remove testsuite.

	[gdb/testsuite] Fix gdb.guile/scm-breakpoint.exp with guile 3.0
	When running test-case gdb.guile/scm-breakpoint.exp on openSUSE Tumbleweed
	with guile 3.0, I run into:
	...
	(gdb) guile (define cp (make-breakpoint "syscall" #:type BP_CATCHPOINT))^M
	ERROR: In procedure make-breakpoint:^M

	(gdb) FAIL: gdb.guile/scm-breakpoint.exp: test_catchpoints: \
	  create a catchpoint via the api
	...

	The same test passes on openSUSE Leap 15.2 with guile 2.0, where the second
	line of the error message starts with the same prefix as the first:
	...
	ERROR: In procedure gdbscm_make_breakpoint: unsupported breakpoint type in \
	  position 3: "BP_CATCHPOINT"^M
	...

	I observe the same difference in many other tests, f.i.:

	Error while executing Scheme code.^M
	(gdb) PASS: gdb.guile/scm-math.exp: catch error in guile type conversion
	...
	but it doesn't cause FAILs anywhere else.

	Fix this by updating the regexp to make the "ERROR: " prefix optional.

	Tested on x86_64-linux, with both guile 2.0 and 3.0.

	gdb: introduce iterator_range, remove next_adapter
	I was always a bit confused by next_adapter, because it kind of mixes
	the element type and the iterator type.  In reality, it is not much more
	than a class that wraps two iterators (begin and end).  However, it
	assumes that:

	 - you can construct the begin iterator by passing a pointer to the
	   first element of the iterable
	 - you can default-construct iterator to make the end iterator

	I think that by generalizing it a little bit, we can re-use it at more
	places.

	Rename it to "iterator_range".  I think it describes a bit better: it's
	a range made by wrapping a begin and end iterator.  Move it to its own
	file, since it's not related to next_iterator anymore.

	iterator_range has two constructors.  The variadic one, where arguments
	are forwarded to construct the underlying begin iterator.  The end
	iterator is constructed through default construction.  This is a
	generalization of what we have today.

	There is another constructor which receives already constructed begin
	and end iterators, useful if the end iterator can't be obtained by
	default-construction.  Or, if you wanted to make a range that does not
	end at the end of the container, you could pass any iterator as the
	"end".

	This generalization allows removing some "range" classes, like
	all_inferiors_range.  These classes existed only to pass some arguments
	when constructing the begin iterator.  With iterator_range, those same
	arguments are passed to the iterator_range constructed and then
	forwarded to the constructed begin iterator.

	There is a small functional difference in how iterator_range works
	compared to next_adapter.  next_adapter stored the pointer it received
	as argument and constructeur an iterator in the `begin` method.
	iterator_range constructs the begin iterator and stores it as a member.
	Its `begin` method returns a copy of that iterator.

	With just iterator_range, uses of next_adapter<foo> would be replaced
	with:

	  using foo_iterator = next_iterator<foo>;
	  using foo_range = iterator_range<foo_iterator>;

	However, I added a `next_range` wrapper as a direct replacement for
	next_adapter<foo>.  IMO, next_range is a slightly better name than
	next_adapter.

	The rest of the changes are applications of this new class.

	gdb/testsuite: restore configure script
	Commit f99d1d37496f ("Remove gdb/testsuite/configure") removed
	gdb/testsuite/configure, as anything gdb/testsuite/configure did could
	be done by gdb/configure.

	There is however one use case that popped up when this changed
	propagated to downstream consumers, to run the testsuite on an already
	built GDB.  In the workflow of ROCm-GDB at AMD, a GDB package is built
	in a CI job.  This GDB package is then tested on different machines /
	hardware configurations as part of other CI jobs.  To achieve this,
	those CI jobs only configure the testsuite directory and run "make
	check" with an appropriate board file.

	In light of this use case, the way I see it is that gdb/testsuite could
	be considered its own project.  It could be stored in a completely
	different repo if we want to, it just happens to be stored inside gdb/.

	Since the only downside of having gdb/testsuite/configure is that it
	takes a few more seconds to run, but on the other hand it's quite useful
	for some people, I propose re-adding it.

	In a sense, this is revert of f99d1d37496f, but it's not a direct
	git-revert, as some things have changed since.

	Update gdb performance testsuite to be compatible with Python 3.8
	Running "make check-perf" on a system with Python 3.8 (e.g., Ubuntu
	20.04) runs into this Python problem:

	  Traceback (most recent call last):
	    File "<string>", line 1, in <module>
	    File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/perftest.py", line 65, in run
	      self.execute_test()
	    File "<string>", line 35, in execute_test
	    File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/measure.py", line 45, in measure
	      m.start(id)
	    File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/measure.py", line 102, in start
	      self.start_time = time.clock()
	  AttributeError: module 'time' has no attribute 'clock'
	  Error while executing Python code.
	  (gdb) FAIL: gdb.perf/single-step.exp: python SingleStep(1000).run()

	... many times over.

	The problem is that the testsuite is using time.clock(), deprecated in
	Python 3.3 and finaly removed in Python 3.8.  The guidelines say to
	use time.perf_counter() or time.process_time() instead depending on
	requirements.  Looking at the current description of those functions,
	at:

	   https://docs.python.org/3.10/library/time.html

	we have:

	   time.perf_counter() -> float

	       Return the value (in fractional seconds) of a performance
	       counter, i.e. a clock with the highest available resolution to
	       measure a short duration. It does include time elapsed during
	       sleep and is system-wide. (...)

	   time.process_time() -> float

	       Return the value (in fractional seconds) of the sum of the
	       system and user CPU time of the current process. It does not
	       include time elapsed during sleep. It is process-wide by
	       definition. (...)

	I'm thinking that it's just best to record both instead of picking
	one.  So this patch replaces the MeasurementCpuTime measurement class
	with two new classes -- MeasurementPerfCounter and
	MeasurementProcessTime.  Correspondingly, this changes the reports in
	testsuite/perftest.log -- we have two new "perf_counter" and
	"process_time" measurements and the "cpu_time" measurement is gone.  I
	don't suppose breaking backward compatibility here is a big problem.
	I suspect no one is really tracking long term performance using the
	perf testsuite today.  And if they are, it shouldn't be hard to adjust.

	For backward compatility, with Python < 3.3, both perf_counter and
	process_time use the old time.clock.

		    Pedro Alves  <pedro@palves.net>

		* gdb.perf/lib/perftest/perftest.py: Import sys.
		(time.perf_counter, time.process_time): Map to time.clock on

		(MeasurementCpuTime): Delete, replaced by...
		(MeasurementPerfCounter, MeasurementProcessTime): .. these two new
		classes.
		* gdb.perf/lib/perftest/perftest.py: Import MeasurementPerfCounter
		and MeasurementProcessTime instead of MeasurementCpuTime.
		(TestCaseWithBasicMeasurements): Use MeasurementPerfCounter and
		MeasurementProcessTime instead of MeasurementCpuTime.

	gdb.perf/: FAIL on Python errors, avoid "ERROR: internal buffer is full"
	Currently, if you run make check-perf on a system with Python 3.8,
	tests seen to PASS, but they actually test a lot less than intended,
	due to:

	 PerfTest::assemble, run ...
	 python BackTrace(64).run()
	 Traceback (most recent call last):
	   File "<string>", line 1, in <module>
	   File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/perftest.py", line 65, in run
	     self.execute_test()
	   File "<string>", line 49, in execute_test
	   File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/measure.py", line 45, in measure
	     m.start(id)
	   File "/home/pedro/rocm/gdb/src/gdb/testsuite/gdb.perf/lib/perftest/measure.py", line 102, in start
	     self.start_time = time.clock()
	 AttributeError: module 'time' has no attribute 'clock'
	 Error while executing Python code.
	 (gdb) PASS: gdb.perf/backtrace.exp: python BackTrace(64).run()

	And then, after fixing the above Python compatibility issues (which
	will be a separate patch), I get 86 instances of overflowing expect's
	buffer, like:

	  ERROR: internal buffer is full.
	  UNRESOLVED: gdb.perf/single-step.exp: python SingleStep(1000).run()

	This patch fixes both problems by adding & using a gdb_test_python_run
	routine that:

	 - checks for Python errors
	 - consumes output line by line

	[gdb/testsuite] Remove read1 timeout factor from gdb.base/info-macros.exp
	At the moment some check-read1 timeouts are handled like this in
	gdb.base/info-macros.exp:
	...
	gdb_test_multiple_with_read1_timeout_factor 10 "$test" $testname {
	  -re "$r1$r2$r3" {
	     pass $testname
	  }
	  -re ".*#define TWO.*\r\n$gdb_prompt" {
	     fail $testname
	  }
	  -re ".*#define THREE.*\r\n$gdb_prompt" {
	     fail $testname
	  }
	  -re ".*#define FOUR.*\r\n$gdb_prompt" {
	     fail $testname
	  }
	}
	...
	which is not ideal.

	We could use gdb_test_lines, but it currently doesn't support verifying
	the absence of regexps, which is done using the clauses above calling fail.

	Fix this by using gdb_test_lines and adding a -re-not syntax to
	gdb_test_lines, such that we can do:
	...
	gdb_test_lines $test $testname $r1.*$r2 \
	    -re-not "#define TWO" \
	    -re-not "#define THREE" \
	    -re-not "#define FOUR"
	...

	Tested on x86_64-linux, whith make targets check and check-read1.

	Also observed that check-read1 execution time is reduced from 6m35s to 13s.

	[gdb/symtab] Fix skipping of import of C++ CU
	Tom Tromey observed that when changing the language in
	gdb.dwarf2/imported-unit-bp.exp from c to c++, the test failed.

	This is due to this code in process_imported_unit_die:
	...
	      /* We're importing a C++ compilation unit with tag DW_TAG_compile_unit
	         into another compilation unit, at root level.  Regard this as a hint,
	         and ignore it.  */
	      if (die->parent && die->parent->parent == NULL
	          && per_cu->unit_type == DW_UT_compile
	          && per_cu->lang == language_cplus)
	        return;
	...
	which should have a partial symtabs counterpart.

	Add the missing counterpart in process_psymtab_comp_unit.

	Tested on x86_64-linux (openSUSE Leap 15.2), no regressions for config:
	- using default gcc version 7.5.0
	  (with 5 unexpected FAILs)
	- gcc 10.3.0 and target board

	Simplify debug_names index writing
	This changes the .debug_names writer to find the TU indices in the
	main loop over all CUs and TUs.  (An earlier patch applied this same
	treatment to the .gdb_index writer.)

	Simplify gdb_index writing
	write_gdbindex writes the CUs first, then walks the signatured type
	hash table to write out the TUs.  However, now that CUs and TUs are
	unified in the DWARF reader, it's simpler to handle both of these in
	the same loop.

	Minor cleanup to addrmap_index_data::previous_valid
	This changes addrmap_index_data::previous_valid to a bool, and
	initializes it inline.

2021-07-05  Tom Tromey  <tom@tromey.com>

	Fix oddity in write_gdbindex
	My recent patch to unify CUs and TUs introduced an oddity in
	write_gdbindex.  Here, we pass 'i' to recursively_write_psymbols, but
	we must instead pass 'counter', to handle the situation where a TU is
	mixed in with the CUs.

	I am not sure a test case for this is possible.  I think it can only
	happen when using DWARF 5, where a TU appears in .debug_info.
	However, this situation is already not handled correctly by
	.gdb_index.  I filed a bug about this.

	ld: Cache and reuse the IR archive file descriptor
	Linker plugin_object_p opens the IR archive for each IR archive member.
	For GCC plugin, plugin_object_p closes the archive file descriptor.  But
	for LLVM plugin, the archive file descriptor remains open.  If there are
	3000 IR archive members, there are 3000 file descriptors for them.  We
	can run out of file descriptors petty easily.

	1. Add archive_plugin_fd and archive_plugin_fd_open_count to bfd so that
	we can cache and reuse the IR archive file descriptor for all IR archive

	[gdb/testsuite] Fix fail in gdb.fortran/ptype-on-functions.exp with gcc-7
	Since commit 05b85772061 "gdb/fortran: Add type info of formal parameter for

	...
	(gdb) ptype say_string^M
	type = void (character*(*), integer(kind=4))^M
	(gdb) FAIL: gdb.fortran/ptype-on-functions.exp: ptype say_string
	...

	The part of the commit causing the fail is:
	...
	 gdb_test "ptype say_string" \
	-    "type = void \\(character\\*\\(\\*\\), integer\\(kind=\\d+\\)\\)"
	+    "type = void \\(character\[^,\]+, $integer8\\)"
	...
	which fails to take into account that for gcc-7 and before, the type for
	string length of a string argument is int, not size_t.

	Fix this by allowing both $integer8 and $integer4.

	Tested on x86_64-linux, with gcc-7 and gcc-10.

	gdb: fall back on sigpending + sigwait if sigtimedwait is not available
	The macOS platform does not provide sigtimedwait, so we get:

	      CXX    compile/compile.o
	    In file included from /Users/smarchi/src/binutils-gdb/gdb/compile/compile.c:46:
	    /Users/smarchi/src/binutils-gdb/gdb/../gdbsupport/scoped_ignore_signal.h:69:4: error: use of undeclared identifier 'sigtimedwait'
	              sigtimedwait (&set, nullptr, &zero_timeout);
	              ^

	An alternative to sigtimedwait with a timeout of 0 is to use sigpending,
	to first check which signals are pending, and then sigwait, to consume
	them.  Since that's slightly more expensive (2 syscalls instead of 1),
	keep using sigtimedwait for the platforms that provide it, and fall back
	to sigpending + sigwait for the others.

	The solib_create_inferior_hook call in symbol_file_command was added by
	commit ea142fbfc9c1 ("Fix breakpoints on file reloads for PIE
	binaries").  It causes solib_create_inferior_hook to be called while
	the inferior is not running, which darwin_solib_create_inferior_hook
	does not expect.  darwin_solib_get_all_image_info_addr_at_init, in
	particular, assumes that there is a current thread, as it tries to get
	the current thread's regcache.

	Fix it by adding a target_has_execution check and returning early.  Note
	that there is a similar check in svr4_solib_create_inferior_hook.

	gdb/ChangeLog:

		* solib-darwin.c (darwin_solib_create_inferior_hook): Return
		early if no execution.

	Use 'bool' more idiomatically in dwarf_decode_lines
	I noticed a couple of spots related to dwarf_decode_lines where the
	'include_p' field was not being used idiomatically -- it is of type
	bool now, so treat it as such.

	gdb/ChangeLog
	2021-07-03  Tom Tromey  <tom@tromey.com>

		* dwarf2/read.c (lnp_state_machine::record_line): Use 'true'.
		(dwarf_decode_lines): Remove '=='.
