The recent commit b601c58034ed755fb765fc13782b6876bffd25d4 causes the
gdb configure to fail if --enable-targets=all was requested, but 64 bit
bfd was not enabled. This was due to a build failure first reported
against mips, and that I also encountered building on a 32 bit mips
system, but that looked like a general failure.
Further examination showed that this is, in fact, mips-specific (or at
least, not completely generic) as other targets like debian-i386 and
32-bit arm could build all targets just fine.
This commit restricts the new error to only trigger in mips hosts.

Commit 1c525b0e037 ("[gdb/tui] Fix assert in
tui_source_window_base::refresh_window") added an early return in
tui_source_window_base::refresh_window.
Assert after the early return that "m_pad != nullptr", and clean up the
following asserts that allow for m_pad == nullptr.
Tested on x86_64-linux.

inline-section-gc.exp ends up passing "-lm" to gnatmake as an "marg"
-- meaning gnatmake should process it itself. However, the gnat-llvm
gnatmake does not know what to do with this, so the test fails.
This patch rearranges the arguments so that the (implicit) trailing
-lm ends up being passed through to the linker.

When running test-case gdb.ada/convvar_comp.exp on s390x-linux, I get:
...
(gdb) run ^M

(gdb) print item.started^M
Cannot access memory at address 0x0^M
(gdb) FAIL: gdb.ada/convvar_comp.exp: print item.started
...
This happens as follows.
The parameter item is available in (DW_OP_fbreg: -168):
...
<2><912>: Abbrev Number: 18 (DW_TAG_formal_parameter)
<913> DW_AT_name : (indirect string, offset: 0x14ca): item
<919> DW_AT_type : <0x929>
<91d> DW_AT_location : 3 byte block: 91 d8 7e (DW_OP_fbreg: -168)
...
and according to the rules of -O0, it's considered to be available after the
prologue, which looks like this:
...
0000000001002998 <pck__break_me>:
1002998: b3 c1 00 2b ldgr %f2,%r11
100299c: b3 c1 00 0f ldgr %f0,%r15

10029aa: e3 20 b0 a0 00 24 stg %r2,160(%r11)
...
To detect the prologue, gdb checks the line info, which looks like this:
...
pck.adb:
File name Line number Starting address View Stmt
pck.adb 17 0x1002998 x
pck.adb 17 0x1002998 1 x
pck.adb 19 0x10029b0 x
pck.adb 20 0x10029b8 x
pck.adb - 0x10029c6
...
and gdb concludes that it's an empty prologue, so we stop at 0x1002998 and
try to print parameter item, which is not available yet.
For more details, see this comment in skip_prologue_using_sal:
...
/* For languages other than assembly, treat two consecutive line
entries at the same address as a zero-instruction prologue.
...
The same thing happens on x86_64-linux, but it causes no problem there,
because amd64_skip_prologue decides not to trust the result:
...
struct compunit_symtab *cust = find_pc_compunit_symtab (func_addr);
/* LLVM backend (Clang/Flang) always emits a line note before the
prologue and another one after. We trust clang and newer Intel
compilers to emit usable line notes. */
if (post_prologue_pc
&& (cust != NULL
&& cust->producer () != nullptr
&& (producer_is_llvm (cust->producer ())
|| producer_is_icc_ge_19 (cust->producer ()))))
return std::max (start_pc, post_prologue_pc);
...
because the producer is GCC.
Work around this by setting a breakpoint on the first statement of
pck.break_me instead.

When I run:
runtest dw2-using-debug-str.exp
... if I examine the gdb.log, I see:
objcopy: unable to copy file '[...]/dw2-using-debug-str'; reason: Text file busy
This happens because the inferior is still running, and objcopy --
despite the invocation seemingly not needing this -- tries to open it
for writing.
This patch works around the objcopy oddity by having gdb exit (killing
the inferior) before the invocation.
Fixing this points out that the test does not work in the
--target_board=cc-with-gdb-index case. This patch also arranges to
issue an "untested" here.

The Rust compiler emits tuple type names with a space after the comma,
like "(i32, f64)". This changes rust-parse.c to follow. This isn't
ideal -- probably the DWARF reader should canonicalize these names --
but it is a bit more robust if symbol lookup should change; and anyway
this feature of gdb is probably rarely used.

When the changes on the remote protocol are made,
we want to test all the corner cases to prevent
regressions. Currently it can be tricky to simulate
some corner case conditions that would expose possible
regressions. When I want to add or change the remote
protocol packet, I need to hack gdbserver to send a
corrupted packet or an error to make sure GDB is able
to handle such a case.
This test makes it easy to send a corruped packet or
an error message to GDB using the gdbreplay tool and
check GDB deals with it as we expect it to.
This test starts a communication with gdbsever setting
the remotelog file. Then, it modifies the remotelog with
update_log proc, injects an error message instead of
the expected replay to the vMustReplyEmpty packet in order
to test GDB reacts to the error response properly. After
the remotelog modification, this test restarts GDB and starts
communication with gdbreply instead of the gdbserver using
the remotelog.
Add a lib/gdbreplay-support.exp. update_log proc matches lines
from GDB to gdbserver in a remotelogfile. Once a match is found then
the custom line is used to build a replacement line to send from
gdbserver to GDB.

insertion order starting python 3.7 (though cpython does this starting python
3.6).
Fix this in the same way as in commit 362a867f2ac ("[gdb/testsuite] Handle

show_index_cache_command prints whether the index-cache is enabled.
This text was added back in 2018 in commit 87d6a7aa (Add DWARF index
cache). Then in 2021, the enabling option was changed via commit
7bc5c369 (gdb: introduce "set index-cache enabled", deprecate "set
index-cache on/off").
This latter change made this output, IMO, redundant. That is,
currently gdb will show:
(gdb) show index-cache

index-cache enabled: The index cache is off.

The index cache is currently disabled.
This patch removes the redundant output.

This changes the help command to use the new command style when
displaying text like:
List of "catch" subcommands:
As a side effect, this mildly -- but not hugely -- cleans up some i18n
issues in help_list. The header comment for that function is also
changed to the gdb style.
Finally, this function used to print something like:
Type "help catch" followed by catch subcommand name for full documentation.
The second "catch" here seems redundant to me, so this patch removes
it.

I think there is no need to have a prefix command that simply calls
help_list. Instead, add_basic_prefix_cmd can be used. This patch

The assert in tui_source_window_base::refresh_window triggers while preparing

The problem is that the window is in a state in which the pad is not used,
because m_content.empty () == true. Instead, it simply shows

We found that the gdb.ada/import.exp test fails when 'mold' is used as
the linker. This happens because mold decides to mark most of the
symbols in the executable as being file-local. I tend to think this
choice, while non-traditional, is probably fine. So, this patch fixes
the problem by changing the relevant Ada code to look for file-local
symbols as well.
Furthermore, there are two overloads of lookup_minimal_symbol_linkage
that both have a final 'bool' parameter -- but with radically
different meanings. This patch somewhat clears up this confusion as
well.

This mailing list discussion:
https://inbox.sourceware.org/gdb-patches/CAOp6jLYD0g-GUsx7jhO3g8H_4pHkB6dkh51cbyDT-5yMfQwu+A@mail.gmail.com
highlighted the following issue with GDB's 'x' packet implementation.
Unfortunately, LLDB also has an 'x' packet, but their implementation
is different to GDB's and so targets that have implemented LLDB's 'x'
packet are incompatible with GDB.
The above thread is specifically about the 'rr' tool, but there could
be other remote targets out there that have this problem.
The difference between LLDB and GDB is that GDB expects a 'b' prefix
on the reply data, while LLDB does not. The 'b' is important as it
allows GDB to distinguish between an empty reply (which will be a 'b'
prefix with no trailing data) and an unsupported packet (which will be
a completely empty packet). It is not clear to me how LLDB
distinguishes these two cases.
See for discussion of the 'x' packet:
https://inbox.sourceware.org/gdb-patches/cover.1710343840.git.tankut.baris.aktemur@intel.com/#r
with the part specific to the 'b' marker in:
https://inbox.sourceware.org/gdb-patches/87msq82ced.fsf@redhat.com/
I propose that we add a new feature 'binary-upload' which can be
reported by a stub in its qSupported reply. By default this feature
is "off", meaning GDB will not use the 'x' packet unless a stub
advertises this feature.
I have updated gdbserver to send 'binary-upload+', and when I examine
the gdbserver log I can see this feature being sent back, and then GDB
will use the 'x' packet.
When connecting to an older gdbserver, the feature is not sent, and
GDB does not try to use the 'x' packet at all.
I also built the latest version of `rr` and tested using current HEAD
of master, where I see problems like this:
(rr) x/10i main
0x401106 <main>: Cannot access memory at address 0x401106
Then tested using this patched version of GDB, and now I see:
(rr) x/10i main
0x401106 <main>: push %rbp
0x401107 <main+1>: mov %rsp,%rbp
0x40110a <main+4>: mov 0x2f17(%rip),%rax # 0x404028 <global_ptr>
... etc ...
and looking in the remote log I see GDB is now using the 'm' packet
instead of the 'x' packet.

As PR sim/28684 explains, it isn't possible to compile GDB with all
targets enabled and not enabling 64 bit bfd. In 64 bit hosts, 64 bit bfd
is forced, so the build works, but in 32 bit hosts, that has to be
explicitly enabled.
I ran into this when I tried compiling GDB on a mips64 machine running a
32 bit OS. Along with the errors in the PR, several other architectures
are also required, notably aarch64 and other explicitly 64bit targets.
Additionally, some 32 bit files required for the gdb mips target aren't
added to the makefile.
Considering the last comment in the bug says this isn't going to be
fixed on the binutils side, I didn't think it was worth trying to fix
the GDB side. Instead, this commit causes the configure script to fail
if all targets were requested and 64 bit bfd isn't enabled. If that is
ever fixed, we can revert this commit.
I considered adding this to the top level configure script, but couldn't
figure out how to detect the situation in there, so this was my next
best idea.

When building gdb with an older makeinfo (4.13), I run into:
...
gdb/doc/gdb.texinfo:42613: warning: `.' or `,' must follow @xref, not `f'.
...
This is related to this line:
...
@xref{Standard Replies} for standard error responses, and how to
respond indicating a command is not supported.
...
Fix this by adding a comma.
Tested by rebuilding the docs.

When building gdb with gcc 7.5.0, I run into:
...
gdb/dwarf2/cooked-index.c: In lambda function:
gdb/dwarf2/cooked-index.c:104:5: error: \
the value of ‘_sch_tolower’ is not usable in a constant expression
};
^
In file included from gdbsupport/gdb-safe-ctype.h:47:0,
from gdb/dwarf2/cooked-index.c:34:
include/safe-ctype.h:111:29: note: ‘_sch_tolower’ was not declared ‘constexpr’
extern const unsigned char _sch_tolower[256];
^~~~~~~~~~~~
...
This does not happen with gcc 8.2.1.
Fix this by dropping the constexpr on lambda function munge in
cooked_index_entry::compare for gcc 7.
Tested by completing the build on x86_64-linux.

Fix this by using lowercase letters in the @sc argument, similar to how that
was done in commit c96452ad168 ("Use lower-case in @sc in the documentation").

In commit 64a97606 ("Support template lookups in
strncmp_iw_with_mode"), gdb was changed so that a command like "break
func<templ>" would match instantiations like "func<templ<int>>".
The new indexer does not support this and so this is a regression.
This went unnoticed because gdb.linespec.cpcompletion.exp puts all
these functions into the main file, and this CU is expanded early.
This patch fixes the bug by changing the cooked index entry comparison
function. It also updates the test to fail without this fix.
Regression tested on x86-64 Fedora 40.

In RISC-V, the general registers can be shown in their abi
form (e.g. sp, a0) or their numeric form (e.g. x2, x10).
Depending on context/preference, someone may prefer to
see one form over the other. The disassembler already
supports this configuration, which can be changed using
the 'set disassembler-options numeric' command.
This commit adds a new set/show command to change gdb's
preference: 'set riscv numeric-registers-names on/off'.
If on, 'info registers' and other situations will print
the numeric register names, rather than the abi versions.
The alias generation has been modified so that the abi
versions are still available for access if specifically
requested such as 'print $ra'. This was done by changing
the behaviour of the code which adds the aliases: all
register names will be added as aliases, even if the name
is the primary one.
There is also no functional downside to adding aliases
which are surplus-to-requirement, since they will be
ignored if there is a 'true' register with the same
name.
