This commit reworks the _active_linker_namespaces convenience variable
following Simon's feedback here:
https://sourceware.org/pipermail/gdb-patches/2025-August/219938.html
This patch implements the renaming to _linker_namespace_count (following
the standard set by _inferior_thread_count) and makes the convenience
variable more resilient in the multi-inferior case by providing a new
function, solib_linker_namespace_count, which counts gets the count of
namespaces using the solib_ops of the provided program_space

This function can't return a NULL pointer, so make it return a reference
instead.

I made a stupid mistake in the commit 28520d7, allow to assemble slli/srli/srai
with 0 immediate to hint c.slli/c.srli/c.srai. These hints will be regared as
illegal instruction for gdb and qemu, so at least I got following gcc testcases
failed,
=== g++: Unexpected fails for rv64gc lp64d medlow ===

So we should just allow c.slli/c.srli/c.srai with zero immediate as hints, but
don't allow slli/srli/srai with zero immediate.

Apparently the cloudabi project is dead. The cloudabi support branded
object files with ELFOSABI_CLOUDABI but other than that didn't do much.

Stop using AC_HEADER_STDC since it is no longer supported in autoconf
2.72+. We require a C++ compiler that supports c++17, it's probably
safe to assume that the C compiler fully supports C89.

A previous commit 09292f4ae2c introduced the new test cfi-common-10.d.
The testcase needs some adjustments for it to be useful on a variety of

While looking at the watchpoint code, I realised that AArch64, ARM,
and Loongarch all override watchpoint_addr_within_range with an
implementation that is the same as the default (but with the logic
written slightly differently).
Compare the deleted functions to default_watchpoint_addr_within_range
in target.c.
The only other targets that override watchpoint_addr_within_range are
ppc_linux_nat_target and remote_target, in both cases the
implementation is different to the default.
Lets remove these unnecessary overrides, and just use the default.
There should be no user visible changes after this commit.

The enum address_class and related fields and methods seem misnamed to
me. Generalize it to "location_class". The enumerators in
address_class are already prefixed with LOC, so the new name seems
logical to me. Rename related fields and methods as well.
Plus, address_class could easily be mistaken for other unrelated things
named "address class" in GDB or DWARF.
Tested by rebuilding.

I spotted this while reviewing a patch adding a new
gdbarch_software_single_step implementation. I find the name
"software_single_step" a bit misleading or unclear. It makes it sounds
as if the function executed a single step. In reality, this function
returns the possible next PCs for current instructions.
We have a similar concept in GDBserver:
linux_process_target::low_get_next_pcs. I like that name, it's clear
and straight to the point.
Rename gdbarch_software_single_step to gdbarch_get_next_pcs. I find
this name more indicative of what happens.
There is some code for ARM shared between GDB and GDBserver to implement
both sides, also called "get next pcs", so I think it all fits well
together.
Tested by rebuilding.

After enabling the ld-elfvers tests on Solaris/x86, one of them FAILs on
Solaris/amd64 only:
FAIL: vers26b3
/ld-new: tmpdir/vers26b3.o: relocation R_X86_64_32 against symbol `foo' can not be used when making a shared object; recompile with -fPIC
./ld-new: failed to set dynamic section sizes: bad value
The error is strange: vers26b3.o *was* compiled with -fPIC and repeating
the link with /bin/ld just works. However, the resulting vers26b3.so
fails to load:
$ ldd -r tmpdir/vers26b3.so
[...]
ld.so.1: vers26b3.so.ld: fatal: relocation error: R_AMD64_32: file tmpdir/vers26b3.so.ld: symbol foo: value 0x7fff34d00830 does not fit
When running the test on Linux/x86_64, it fails with the same ld message
as above, so the test is marked unsupported for both Linux/x86_64 and
Solaris/amd64.
Tested on {amd64,i386}-pc-solaris2.11 and {x86_64,i686}-pc-linux-gnu.

All ld-elfvers tests FAIL on Solaris/SPARC, always with the same failure
mode:
FAIL: vers1
./ld-new: _etext: undefined version: vers1.so
./ld-new: _end: undefined version: vers1.so
./ld-new: _edata: undefined version: vers1.so
./ld-new: failed to set dynamic section sizes: bad value
This is due to the use of --no-undefined-version, the error being
emitted by bfd/elflink.c (bfd_elf_size_dynamic_sections). The affected
symbols are mandated by the Solaris ABI in versioned shared objects and
are generated by ld/emultempl/solaris2.em
(elf_solaris2_before_allocation). The check in
bfd_elf_size_dynamic_sections fails since for the base version (vers1.so),
both symver and script are 0:
vers1.so pattern = "_etext", literal = 1, symver = 0, script = 0, mask = 1
Given that those symbols are generated internally by ld, it seems
sensible to set script = 1 for them.
This patch does just that, at the same time enabling the tests for
Solaris/x86. Not doing this before looks like an oversight: there's no
difference between SPARC and x86 in this regard.
This introduces one failure on Solaris/amd64 (vers26b3), which I'll
address in a followup.
Tested no {sparc,sparcv9}-sun-solaris2.11, {i386,amd64}-pc-solaris2.11,
and {x86_64,i686}-pc-linux-gnu.

Fix a failing test introduced by this commit:
commit e53b88b40ed38651b50f954dfe76066822094c15
Date: Wed Aug 13 15:29:38 2025 +0100
gdb: fix forward/reverse search, when no lines are printed
The TUI test added in this commit assumed that the opening '{' of main
would be the first statement line (in DWARF terms), and so, would be
the initial focus of the TUI src window.
This is true for some targets (e.g. x86), but not
others (e.g. AArch64), and so gdb.tui/source-search.exp was seen
failing on at least some AArch64 targets.
Fix this by adding a 'list' command to the test, which forces the
initial window contents to be as needed for the rest of the test.

I noticed that the alignment of the .text and .data sections on
Solaris/x86 doesn't match what /bin/ld does: gld uses the original i386
psABI default of 0x1000, while Solaris has moved to larger values as can
be seen both in the Oracle Solaris 11.4 Linkers and Libraries Guide,
ch. 15, Program Loading and Dynamic Linking, p. 15-6 and the system
headers (<sys/elf_{i386,amd64}.h>) that have
while the Solaris/SPARC values are already correct.
To fix this, on i386 it's sufficient to redefine ELF_MAXPAGESIZE. On
x86_64, unlike i386, ELF_COMMONPAGESIZE is hardcoded as 0x1000, the
default, so setting ELF_MAXPAGESIZE has no effect on ELF_P_ALIGN.
Setting ELF_COMMONPAGESIZE to ELF_MAXPAGESIZE, too, fixes that and
brings both target in sync. ELF_MACHINE_CODE is just set to the original
value again, so it's removed.
Tested on {i386,amd64}-pc-solaris2.11, {i686,x86_64}-pc-linux-gnu, and
amd64-pc-freebsd14.0.

eh_frame textual dump was not correct when the cfa_offset is a large
value. The reason is that the dumping code generally assumes the
cfa_offset is an 'int'.
cfa_offset values can be updated by various DWARF opcodes, like:
- DW_CFA_def_cfa, DW_CFA_def_cfa_offset which bring unsigned leb128
cfa_offset
- DW_CFA_def_cfa_sf, DW_CFA_def_cfa_offset_sf which bring signed
leb128 cfa_offset
Internally, the routines in dwarf.c keep the value as 'uint64_t
cfa_offset'. That size of the datatype is expected to work for most of
the real-world cases. Care, however, needs to be taken when it comes
to the signedness of the value. Fix the buggy behavior by adding an
additional field to track whether the value of cfa_offset is signed or
unsigned and display accordingly for "frames-interp" output.
The display of cfa_offset had issues in both "frames-interp" output
(objdump -WF or do_debug_frames_interp) and the "frames" output.
Add two new tests: cfi-common-10.s uses a large positive cfa_offset
(with "frames output), and cfi-x86_64-2.s uses a negative cfa_offset
(with "frames-interp" output).
ChangeLog:
* binutils/dwarf.c (frame_display_row): Update format string
based on signedness.

cfa_offset using PRIu64 or PRId64 as applicable.

i.e. there's a positive offset from the GOT instead of the expected

Use sframe_encoder_add_funcdesc_v2 instead of sframe_encoder_add_funcdesc.
Similarly, use sframe_decoder_get_funcdesc_v2 instead of
sframe_decoder_get_funcdesc.
sframe_encoder_add_funcdesc, and sframe_decoder_get_funcdesc were first
added for SFrame V1. For the purpose of these testcases, the two V2
APIs are (almost) functionally equivalent. In future, we may want to
make sframe_encoder_add_funcdesc and sframe_decoder_get_funcdesc
internal to libsframe only. Using the V2 named APIs is better for
clarity as well.

oss-fuzz generated a total length field of 32, when the header was 40
bytes. Subtracting gave -8ul for the remaining length..
I think we should be sanity checking the total length given in the
header against the remaining buffer length and the size of the header
each time get_version_header is called.
Possibly vallen should be sanity checked inside get_version_header
too, but I'll leave that to someone else.

Several ld CTF tests FAIL on 32-bit SPARC, e.g.
FAIL: Arrays (conflicted)
The failure mode is always the same:
./tmpdir/array-char-conflicting-1.s: Assembler messages:
./tmpdir/array-char-conflicting-1.s:89: Error: Architecture mismatch on "return %i7+8".
./tmpdir/array-char-conflicting-1.s:89: (Requires v9|v9a|v9b|v9c|v9d|v9e|v9v|v9m|m8; requested architecture is sparclite.)
The problem is that gcc emits v8plus code by default, and thus invokes
as with -xarch=v8plus (equivalent to -Av8plus), while the testcase lacks
the latter.
Fixed by setting ASFLAGS to match.
Tested on sparc-sun-solaris2.11, sparc-unknown-linux-gnu,
sparcv9-sun-solaris2.11, and sparc64-unknown-linux-gnu.

Every time we update the gdb version number, test-case gdb.base/default.exp
needs updating because it matches the values of convenience variables
$_gdb_{major,minor} using hardcoded expected values:
...
{$_gdb_major = 17} \
{$_gdb_minor = 1} \
...
I'm assuming the values were hardcoded because gdb_test_list_exact was used.
Since the previous patch, that's not longer the case, so use regexps instead,
getting rid of this annoyance [1].
Tested on x86_64-linux.

An oss-fuzz testcase with a SHT_GROUP section named .debug managed to
break objcopy --compress-debug-sections. The underlying problem is
that SEC_DEBUGGING is set by section name tests, thus the SHT_GROUP
section gets compressed. The compressed section data is smaller than
the original section sh_size, and process_sht_group_entries tries to
look at sh_size worth of entries. The patch fixes this mess by simply
not setting SEC_DEBUGGING on SHT_GROUP sections.
Note that it isn't correct to restrict SEC_DEBUGGING to SHT_PROGBITS
sections, as that will break processor/os special sections for debug.
eg. SHT_MIPS_DEBUG.
* elf.c (_bfd_elf_make_section_from_shdr): Don't set
SEC_DEBUGGING on SEC_GROUP sections no matter their name.

I ran test-case gdb.base/default.exp with make-check-all.sh, and noticed a
FAIL with host/target board local-remote-host-native:
...
FAIL: $exp: show convenience ($_colorsupport = "monochrome" not found)
...
The problem is that part of the test-case relies on "setenv TERM dumb", and
setenv, which is a tcl command (which runs on build), only has effect in gdb
(which runs on host), if build == host, in other words, local host.
I grepped for test-cases using setenv, and ran them with the host/target
board, and fixed the FAILs I saw.
All FAILs have the same cause as I described above, except for
proc test_data_directory in gdb.python/py-parameter.exp, which handles files
assuming local host. I chose to leave it that way, and bail out but add a
comment.
Implementationwise, the change to test-case gdb.base/default.exp is the most
intrusive: it replaces a use of proc gdb_test_list_exact with a use of proc
gdb_get_lines_no_pass, because it allows specifying a regexp match.
In the process, I found out gdb_test_list_exact has a bug, filed as PR33038.
Because of this bug, I had to add matching of convenience variable $_tbl.

While re-testing the TUI tests on x86_64-freebsd, I found that commit
06a53717f7c ("[gdb/testsuite] Handle unrecognized escape sequences better in
tuiterm") broke most test-cases.
Fix this by rewriting this gdb_test_multiple clause:
...
-re "^($re_csi_prefix?)($re_csi_args*)($re_csi_cmd)" {
...
into:
...
-re "^($re_csi_cmd)" {
...
-re "^($re_csi_args*)($re_csi_cmd)" {
...
-re "^($re_csi_prefix?)($re_csi_args*)($re_csi_cmd)" {
...

When encountering an unrecognized escape sequence in Term::accept_gdb_output,
a warning is issued:
...
WARNING: timeout in accept_gdb_output
...
and 0 is returned.
Subsequent calls run into the same problem, so matching doesn't progress.
Consequently, figuring out what the unrecognized escape sequence actually is
depends on analyzing gdb's output as echoed into gdb.log.
In the test added in this commit, gdb (well, a script gdb.tcl emulating gdb)
outputs escape sequence "ESC ( B", which doesn't show up in recognizable form
in gdb.log:
...
foo^M^M
...
and as mentioned the tuiterm screen only show:
...
foo
...
because matching doesn't progress beyond the unrecognized sequence.
Fix this by rewriting accept_gdb_output to match gdb output using a phased
approach that echoes unmatched escape sequences, giving us instead on the
tuiterm screen:
...
foo^[(B
...
[ Since "ESC ( B" is now supported, the test-case has been updated to use
"ESC ( % 5" instead. ]
Tested on x86_64-linux.

The variable Term::_last_char is meant to represent the last char inserted by
Term::_insert, but setting it is done alongside the only call to _insert in
lib/tuiterm.exp:
...
_insert $expect_out(0,string)
variable _last_char
set _last_char [string index $expect_out(0,string) end]
...
Fix this by moving the setting of _last_char to inside _insert.

bfd_check_format currently does not take much notice of the target
set in its abfd arg, merely checking that target first if
target_defaulted is false. As the comment says this was due to
complications with archive handling which I think was fixed in
commit f832531609d0. It should now be possible to just check the
given target, except for linker input files. This will speed checking
the target of the first file in archives, which is done in the process
of matching archive targets.
This will no doubt expose some misuse of target options, as found in
the binutils "efi app" tests.
The stricter checking also exposed some errors. Cris targets gave
"FAIL: objcopy decompress debug sections in archive (reason: unexpected output)"
"FAIL: objcopy decompress debug sections in archive with zlib-gabi (reason: unexpected output)"
without the bfd_generic_archive_p fix. cris has a default target of
cris-aout which doesn't match objects for any of the cris-elf or
cris-linux targets. The problem here was that checking the first
object file in archives didn't match but a logic error there meant
bfd_error_wrong_object_format wasn't returned as it should be. There
was also a possibility of bfd_error_wrong_object_format persisting
from one target check to the next.

Automatically choosing "plugin" for the archive target when plugins
are enabled can result in making archives as specified by the plugin
target vec, ie. COFF style archives (also used by most ELF
binutils targets). This is wrong for aix, hpux, vms, aout, macho
and possibly other targets, if compatibility with target system
archives matters.
This patch removes archive support entirely from the plugin target.
That means an archive will never get past bfd_check_format with a
target of plugin_vec, even if it is opened using "plugin". Instead,
archives will have their elements opened using the plugin target
selected is such a way that the plugin target will be tried first in
bfd_check_format and then continue to try other targets if that fails.
The patch tries to avoid opening archives using "plugin" because that
is guaranteed to fail the first target check in bfd_check_format, but
mm.c still does so, and nested archives will also be opened using
"plugin".
The patch also fixes poor arsup.c plugin support.
