A number of testcases define variables and/or functions which are
referenced by GDB during the test, but which are not referenced from
within the test executable. Clang correctly recognizes that these
variables and functions are unused, and optimizes them out, causing
the testcases in question to fail. This commit adds __attribute__
((used)) in various places to prevent this.

Currently, GDB will only stop the backtrace at the main function if
there is a minimal symbol with the matching name. In Fortran programs
compiled with gfortran this is not the case. The main function is
present in the DWARF, and as marked as DW_AT_main_subprogram, but
there's no minimal symbol.
This commit extends `inside_main_func` to check the full symbols if no
matching minimal symbol is found.
There's an updated test case that covers this change.
gdb/ChangeLog:
* frame.c (inside_main_func): Check full symbols as well as
minimal symbols.
gdb/testsuite/ChangeLog:
* gdb.fortran/mixed-lang-stack.exp (run_tests): Update expected
output of backtrace.

This commit fixes the type of one of the parameters as well as a couple
of temporaries.
While at it, the function's description is slightly rewritten to make it
a little clearer what the function does.
gdb/ChangeLog:
* ada-lang.c (advance_wild_match): Rewrite the function's
description. Change the type of target0, t0 and t1 to char.

The type-safe attribute patch introduced a regression that can occur
when the DW_AT_bit_offset value is negative. This can happen with
some Ada programs.
This patch fixes the problem. It also fixes a minor oddity in the
existing scalar storage test -- this test was intended to assign a
smaller number of bits to the field.

This changes ada_encode to return a std::string. This simplifies it
somewhat, removes a use of GROW_VECT, and is also simpler for callers
to use.

Calling non-pcrel functions from pcrel code requires a stub to set up
r2. Gold created the stub, but an "optimisation" made the stub jump
to the function local entry, ie. r2 was not initialised.
This patch fixes that long branch stub problem, and another that might
occur for plt call stubs to local functions.

GOT relocations can refer directly to a function in a fixed position
executable, unlike ADDR64 which needs a global entry stub, or branch
relocs, which need PLT stubs.
* powerpc.cc (is_got_reloc): New function.
(Target_powerpc::Relocate::relocate): Use it here, exclude GOT
relocs when looking for stubs.

GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250
Update GNU_PROPERTY_X86_ISA_1_XXX macros:
https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13
in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:
#define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
#define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
#define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
#define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)
The previous GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.
Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.
Also add
#define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)
for mask registers.

When printing void results without any format letter, they are output
as expected:
(gdb) p $abcd
$1 = void
(gdb) p (void)10
$2 = void
But if any format letter (besides s) is used, it always outputs zero:
(gdb) p/x $abcd
$3 = 0x0
(gdb) p/x (void)10
$4 = 0x0
So this adds void results to the types handled like unformatted prints.

gdb: Have allocate_target_description return a unique_ptr
There were a few places where we could (should?) have delayed
releasing the target_desc_up until a little later. This commit
catches these cases.
In the case of ARC, the target_desc_up is now exposed right out to
gdbserver, which means making a small change there too.
There should be no user visible changes after this commit.

An issue was reported here related to building GDB on MinGW:
https://sourceware.org/pipermail/gdb/2020-September/048927.html
It was suggested here:
https://sourceware.org/pipermail/gdb/2020-September/048931.html
that the solution might be to make use of $(LIB_GETRANDOM), a variable
defined in the gnulib makefile, when linking GDB.
In fact I think the issue is bigger than just LIB_GETRANDOM. When
using the script binutils-gdb/gnulib/update-gnulib.sh to reimport
gnulib there is a lot of output from gnulib's gnulib-tool. Part of
that output is this:
You may need to use the following makefile variables when linking.
Use them in <program>_LDADD when linking a program, or
in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library.
$(FREXPL_LIBM)
$(FREXP_LIBM)
$(INET_NTOP_LIB)
$(LIBTHREAD)
$(LIB_GETLOGIN)
$(LIB_GETRANDOM)
$(LIB_HARD_LOCALE)
$(LIB_MBRTOWC)
$(LIB_SETLOCALE_NULL)
$(LTLIBINTL) when linking with libtool, $(LIBINTL) otherwise
What I think this is telling us is that we should be including the
value of all these variables on the link line for gdb and gdbserver.
The problem though is that these variables are define in gnulib's
makefile, but are not (necessarily) defined in GDB's makefile.
One solution would be to recreate the checks that gnulib performs in
order to recreate these variables in both gdb's and gdbserver's
makefile. Though this shouldn't be too hard, most (if not all) of
these checks are in the form macros defined in m4 files in the gnulib
tree, so we could just reference these as needed. However, in this
commit I propose a different solution.
Currently, in the top level makefile, we give gdb and gdbserver a
dependency on gnulib. Once gnulib has finished building gdb and
gdbserver can start, these projects then have a hard coded (relative)
path to the compiled gnulib library in their makefiles.
In this commit I extend the gnulib configure script to install a new
makefile fragment in the gnulib build directory. This new file will
have the usual variable substitutions applied to it, and so can
include the complete list (see above) of all the extra libraries that
are needed when linking against gnulib.
In fact the new makefile fragment defines three variables, these are:
LIBGNU: The path to the archive containing gnulib. Can be used as a
dependency as when this file changes gdb/gdbserver should be
relinked.
LIBGNU_EXTRA_LIBS: A list of linker -l.... flags that should be
included in the link line of gdb/gdbserver. These are
libraries that $(LIBGNU) depends on. This list is taken from
the output of gnulib-tool, which is run by our
gnulib/update-gnulib.sh script.
INCGNU: A list of -I.... include paths that should be passed to the
compiler, these are where the gnulib headers can be found.
Now both gdb and gdbserver can include the makefile fragment and make
use of these variables.
The makefile fragment relies on the variable GNULIB_BUILDDIR being
defined. This is checked for in the fragment, and was already defined
in the makefiles of gdb and gdbserver.

Update allocate_target_description to return a target_desc_up, a
specialisation of unique_ptr.
This commit does not attempt to make use of the unique_ptr in the
best possible way, in almost all cases we immediately release the
pointer from within the unique_ptr and then continue as before.
There are a few places where it was easy to handle the unique_ptr, and
in these cases I've done that.
Everything under gdb/features/* is auto-regenerated.
There should be no user visible changes after this commit.

For functions with small (< 256 bytes) stack frames, the current x86
do_calls_non_split ignores --split-stack-adjust-size and, in
combination with __morestack_non_split, supplies a non-split-stack
function with at least 0x100000 (1M) available stack. On powerpc64, a
default of 0x4000 is not large enough to reliably work with the golang
testsuite. This increase the default size to the defacto x86 value.

GDB currently doesn't build cleanly with clang (a -Wdeprecated-copy-dtor
error). I configured my clang-based GDB build with
CXXFLAGS="-Wno-error=deprecated-copy-dtor", so I can use it despite that
problem. However, I found that it had no effect. This is because my
-Wno-error=Wdeprecated-copy-dtor switch is followed by -Werror in the
command line, which switches back all warnings to be errors.
If we want the user-supplied C(XX)FLAGS to be able to override flags
added by our configure script, the user-supplied C(XX)FLAGS should
appear after the configure-supplied flags.
This patch moves the user-supplied CXXFLAGS at the very end of the
compilation command line, which fixes the problem described above. This
means moving it out of INTERNAL_CFLAGS and inlining it in the users of
INTERNAL_CFLAGS.
I observed the problem when building GDB, but the same problem could
happen with GDBserver, so the change is done there too.
In GDBserver, INTERNAL_CFLAGS is passed when linking

"reg < ARC_LAST_REGNUM" for the condition check of the for-loop.
- arc-linux-tdep.c: Use "ARC_LAST_REGNUM < ARRAY_SIZE (...)" instead of
"ARC_LAST_REGNUM <= ARRAY_SIZE (...)" for the "asserts".
- Use "buf + arc_linux_core_reg_offsets[ARC_ERET_REGNUM]" instead of
"buf + REG_OFF (6)".
- Fix a few typos/indentation.
v3 [3]:
- Use gdb_assert_not_reached(text) instead of gdb_assert (!text).
- Remove unnecessary braces in the for loop.

This gdbserver implementation supports ARC ABI v3 and v4 (older ARC ABI
versions are not supported by other modern GNU tools or Linux itself).
Gdbserver supports inspection of ARC HS registers R30, R58 and R59 - feature
that has been added to Linux 4.12. Whether gdbserver build will actually
support this feature depends on the version of Linux headers used to build
the server.
v2 [1]:
- Use "this->read_memory ()" instead of "the_target->read_memory ()".
- Remove the unnecessary "arch-arc.o:" target from the "Makefile.in".
- Got rid of "ntohs()" function and added lots of comments about
endianness.
- Clarify why "pc" value is read from and saved to different fields
in user regs struct.
- In function "is_reg_name_available_p()", use a range-based iterator
to loop over the registers.
- Removed mentioning of issue number that was not related to sourceware.
- A few typo's fixed.

"arc_gdbarch_features" is a data structure containing information
about the ARC architecture: ISA version, register size, etc.
This name is misleading, because although it carries the phrase
"gdbarch", it has nothing to do with the type/interface in GDB.
Traditionaly, "gdbarch" structures are only used for that purpose.
To rectify this, this patch changes the name to "arc_arch_features".

Instead of sharing the native-only code with all BSDs with slightly
different semantics of the kernels, share the NetBSD-only behavior beteen
the NetBSD native and gdbserver setup.
NetBSD does not differentiate the address space I and D in the
operations (contrary to OpenBSD). NetBSD handles EACCES that integrates
with NetBSD specific PaX MPROTECT error handling.
Add a verbose message in the native client that an operation could be
cancelled due to PaX MPROTECT setup.
gdb/ChangeLog:
* nat/netbsd-nat.c (write_memory, read_memory): Add.
* nat/netbsd-nat.h (write_memory, read_memory): Likewise.
* nbsd-nat.c (nbsd_nat_target::xfer_partial): Update.
gdbserver/ChangeLog:
* netbsd-low.cc (netbsd_process_target::read_memory)
(netbsd_process_target::write_memory): Update.

The support is on par with NetBSD/amd64, thus GPR works,
single step and software breakpoint are operational, and the
SVR4 r_debug integration is functional.
gdbserver/ChangeLog:
* netbsd-aarch64-low.cc: Add.
* Makefile.in (SFILES): Register "netbsd-aarch64-low.c".
* configure.srv: Add aarch64*-*-netbsd*.

I noticed that signal_catch_counts is a dynamically-allocated array of
constant size, allocated at startup an never freed. This might as well
be a statically-allocated array.
gdb/ChangeLog:
* break-catch-sig.c (signal_catch_counts): Make a static arrray.
(_initialize_break_catch_sig): Don't allocate array.

gcore is installed on NetBSD, FreeBSD, Solaris (HAVE_NATIVE_GCORE_HOST=1)
and Linux (HAVE_NATIVE_GCORE_TARGET=1). However, even though gcore.1
is installed conditional on those variables, HAVE_NATIVE_GCORE_HOST
was missing from gdb/doc/Makefile.in, so manual installation was
skipped on NetBSD, FreeBSD, and Solaris.
gdb/doc/ChangeLog:
2020-10-06 Michael Forney <mforney@mforney.org>
* Makefile.in (HAVE_NATIVE_GCORE_HOST): Add for gcore.1
install condition.

The register_data() function in gdbserver/regcache.cc has an
input argument called "fetch". This argument is not used by this
static function at all. Therefore, it is time to get rid of it.
gdbserver/ChangeLog:
* regcache.cc (register_data): Remove unused "fetch" argument.

This patch fixes a bogus use of type punning in parse_barrier() which
was causing an assembly failure on big endian LP64 hosts when attempting
to assemble "isb sy" for AArch64.
The type of the entries in aarch64_barrier_opt_hsh is
aarch64_name_value_pair. We were incorrectly casting this to the
locally-defined asm_barrier_opt which has a wider type (on LP64) for the
second member. This happened to work on little-endian hosts but fails on
LP64 big endian.
The fix is to use the correct type in parse_barrier(). This makes the
locally-defined asm_barrier_opt redundant, so remove it.
gas/ChangeLog:
* config/tc-aarch64.c (asm_barrier_opt): Delete.
(parse_barrier): Fix bogus type punning.
* testsuite/gas/aarch64/system.d: Update disassembly.
* testsuite/gas/aarch64/system.s: Add isb sy test.

Two subtests of gdb.base/list.exp failed when built with Clang
because the unused function "unused" was optimized out. This
commit adds __attribute__ ((used)) to both definitions.
