      ada-lang.c::advance_wild_match improve doc and parameter+temporaries types · 59c8a30b
      Joel Brobecker authored 
      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.

      Fix bit offset regression · 7c184d33
      Tom Tromey authored 
      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.

	* dwarf2/read.c (dwarf2_add_field): Handle signed offsets.

      Return std::string from ada_encode · 5c4258f4
      Tom Tromey authored 
      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.

      [GOLD] Power10 segv due to wild r2 · fa40fbe4
      Alan Modra authored 
      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.

      [GOLD] internal error in relocate, at powerpc.cc:10473 · 4290b0ab
      Alan Modra authored 
      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.

      x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker · 32930e4e
      H.J. Lu authored 
      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.

      Handle void results as unformatted prints · 3d87245c
      Hannes Domani authored 
      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.

      gnulib: Ensure all libraries are used when building gdb/gdbserver · 361cb219
      Andrew Burgess authored 
      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.

gdb/ChangeLog:

	* Makefile.in: Include Makefile.gnulib.inc.  Don't define LIBGNU
	or INCGNU.  Make use of LIBGNU_EXTRA_LIBS when linking.

      Update allocate_target_description to return a target_desc_up, a

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.

      gdb: put user-supplied CFLAGS at the end · a038ffd8
      Simon Marchi authored 
      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

gdb/ChangeLog:

	* Makefile.in (COMPILE): Add CXXFLAGS.
	(INTERNAL_CFLAGS_BASE): Remove CXXFLAGS.
	(check-headers): Add CXXFLAGS.

      arc: Add support for Linux coredump files · cc463201
      Anton Kolesov authored 
      With the implemenations in this patch, ARC gdb can handle
coredump related matters.  The binutils counter part of
this patch has already been pushed [1].

v2 [2]:
- arc_linux_collect_gregset: Use "reg <= ARC_LAST_REGNUM" instead of
  "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.

      gdbserver: Add GNU/Linux support for ARC · 6d2d7c56
      Anton Kolesov authored 
      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: Rename "arc_gdbarch_features" struct · e4bd363f
      Shahab Vahedi authored 
      "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".

gdb/ChangeLog:

	* arch/arc.h: Rename "arc_gdbarch_features" to
	"arc_arch_features".
	* arc-tdep.h: Likewise.
	* arc-tdep.c: Likewise.

      In `attach_command`, there is a call to `init_wait_for_inferior`

`init_wait_for_inferior` already calls `clear_proceed_status`.  Remove

      Add common write_memory and read_memory NetBSD routines · 91e5e8db
      Kamil Rytarowski authored 
      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.
