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().

gdb.dlang/demangle.exp: update expected output for _D8demangle4testFnZv
Since commit

demangle _D8demangle4testFnZv^M
demangle.test(typeof(null))^M

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.

- 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

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: 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

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.

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.

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.

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

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.

DT_RELR encodes consecutive R_*_RELATIVE relocations in GOT (the global

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

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.

Replace hand-written tests checking various comparison operators between
various decimal floating point types with a loop to programmatically

suffixes, which lead to the original duplication.
Also add a lot more combinations, testing all comparison operators

patch.
