This patch correspond to the upstream PR:
https://github.com/libffi/libffi/pull/817
And has been merged.

libffi/ChangeLog:

	* src/loongarch64/ffi.c: Avoid defining floats
	in struct call_context if the ABI is soft-float.

Now that C23 support is essentially feature-complete, I'd like to
switch the default language version for C compilation to -std=gnu23.

This requires updating a large number of testcases that fail with the
new language version if left unchanged.  In this patch, update most of
the tests for which there is a safe change that works both before and
after the update to default language version - typically adding the
option -std=gnu17 or -Wno-old-style-definition to the tests.  (There
are also a few tests where I'd like to investigate further why they
fail with -std=gnu23, or where I think such failures show an actual
bug to fix before changing the default language version, or where it
seems more appropriate to make a testcase change that would result in
failures in the absence of the language version change rather than
just adding an option that does nothing with the gnu17 default.)

The libffi test fixes have also been submitted upstream:
<https://github.com/libffi/libffi/pull/861>.

Most of the failures requiring such changes are for one of two
reasons:

* Unprototyped function declarations with () (meaning the same as
  (void) in C23 mode) for a function then called with arguments.

* Old-style function definitions, which warn by default in C23 mode,
  so resulting in test failures for the unexpected warnings.

Other reasons for failures include:

* Tests with their own definitions of bool, true and false.

* Tests of diagnostics (often with -pedantic) in cases where C23 has
  changed semantics, such as:

  - tag compatibility for structs;
  - enum values out of range of int;
  - handing of qualified array types;
  - decimal floating types formerly needing -pedantic diagnostics, but
    being standard in C23.

Bootstrapped with no regressions for x86_64-pc-linux-gnu.

Architecture-specific CFI directives are currently declared an processed
among others architecture-independent CFI directives in gcc/dwarf2* files.
This approach creates confusion, specifically in the case of DWARF
instructions in the vendor space and using the same instruction code.

Such a clash currently happen between DW_CFA_GNU_window_save (used on
SPARC) and DW_CFA_AARCH64_negate_ra_state (used on AArch64), and both
having the same instruction code 0x2d.
Then AArch64 compilers generates a SPARC CFI directive (.cfi_window_save)
instead of .cfi_negate_ra_state, contrarilly to what is expected in
[DWARF for the Arm 64-bit Architecture (AArch64)](https://github.com/
ARM-software/abi-aa/blob/main/aadwarf64/aadwarf64.rst).

This refactoring does not solve completely the problem, but improve the
situation by moving some of the processing of those directives (more
specifically their output in the assembly) to the backend via 2 target
hooks:
- DW_CFI_OPRND1_DESC: parse the first operand of the directive (if any).
- OUTPUT_CFI_DIRECTIVE: output the CFI directive as a string.

Additionally, this patch also contains a renaming of an enum used for
return address mangling on AArch64.

The libffi.closures/single_entry_structs2.c test FAILs on 32-bit SPARC:

FAIL: libffi.closures/single_entry_structs2.c -W -Wall -Wno-psabi -O0
execution test

The issue has been reported, analyzed and fixed upstream:

	Several tests FAIL on 32-bit Solaris/SPARC
	https://github.com/libffi/libffi/issues/841

Therefore this patch imports the fix into the GCC tree.

Tested on sparc-sun-solaris2.11.

	maintain call-by-value semantics.

The recent move of libgfortran object files to subdirs and the resulting
breakage of libgfortran.so symbol exports demonstrated how fragile
deriving object and archive names from their libtool counterparts in the
Makefiles is.  Therefore, this patch moves that step into
make_sunver.pl, considerably simplifying the Makefile rules to create
the version scripts.

Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11, verifying that the version scripts are identical
except for the input filenames.

Recent Darwin versions place contraints on the use of run paths
specified in environment variables.  This breaks some assumptions
in the GCC build.

This change allows the user to configure a Darwin build to use
'@rpath/libraryname.dylib' in library names and then to add an
embedded runpath to executables (and libraries with dependents).

The embedded runpath is added by default unless the user adds
'-nodefaultrpaths' to the link line.

For an installed compiler, it means that any executable built with
that compiler will reference the runtimes installed with the
compiler (equivalent to hard-coding the library path into the name
of the library).

During build-time configurations  any "-B" entries will be added to
the runpath thus the newly-built libraries will be found by exes.

Since the install name is set in libtool, that decision needs to be
available here (but might also cause dependent ones in Makefiles,
so we need to export a conditional).

This facility is not available for Darwin 8 or earlier, however the
existing environment variable runpath does work there.

We default this on for systems where the external DYLD_LIBRARY_PATH
does not work and off for Darwin 8 or earlier.  For systems that can
use either method, if the value is unset, we use the default (which
is currently DYLD_LIBRARY_PATH).

ChangeLog:

	* configure: Regenerate.
	* configure.ac: Do not add default runpaths to GCC exes
	when we are building -static-libstdc++/-static-libgcc (the
	default).
	* libtool.m4: Add 'enable-darwin-at-runpath'.  Act  on the

My previous nm patch handled all cases but one -- if the user set NM in
the environment to a path which contained an option, libtool's nm
detection tries to run nm against a copy of nm with the options in it:
e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
This is unlikely to be desirable: in this case we should run
"/usr/bin/nm --blargle /usr/bin/nm".

Furthermore, as part of this nm has to detect when the passed-in $NM
contains a path, and in that case avoid doing a path search itself.
This too was thrown off if an option contained something that looked
like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
to see whether that nm exists, finds it doesn't, and wrongly concludes
that nm -p or whatever does not work).

Fix all of these by clipping all options (defined as everything
including and after the first " -") before deciding whether nm
contains a path (but not using the clipped value for anything else),
and then removing all options from the path-modified nm before
looking to see whether that nm existed.

NM=my-nm now does a path search and runs e.g.
  /usr/bin/my-nm -B /usr/bin/my-nm

NM=/usr/bin/my-nm now avoids a path search and runs e.g.
  /usr/bin/my-nm -B /usr/bin/my-nm

NM="my-nm -p../wombat" now does a path search and runs e.g.
  /usr/bin/my-nm -p../wombat -B /usr/bin/my-nm

NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
  ../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm

This seems to be all combinations, including those used by GCC bootstrap
(which, before this commit, fails to bootstrap when configured
--with-build-config=bootstrap-lto, because the lto plugin is now using
--export-symbols-regex, which requires libtool to find a working nm,
while also using -B../prev-gcc to point at the lto plugin associated
with the GCC just built.)

Libtool needs to get BSD-format (or MS-format) output out of the system
nm, so that it can scan generated object files for symbol names for
-export-symbols-regex support.  Some nms need specific flags to turn on
BSD-formatted output, so libtool checks for this in its AC_PATH_NM.
Unfortunately the code to do this has a pair of interlocking flaws:

 - it runs the test by doing an nm of /dev/null.  Some platforms
   reasonably refuse to do an nm on a device file, but before now this
   has only been worked around by assuming that the error message has a
   specific textual form emitted by Tru64 nm, and that getting this
   error means this is Tru64 nm and that nm -B would work to produce
   BSD-format output, even though the test never actually got anything
   but an error message out of nm -B.  This is fixable by nm'ing *nm
   itself* (since we necessarily have a path to it).

 - the test is entirely skipped if NM is set in the environment, on the
   grounds that the user has overridden the test: but the user cannot
   reasonably be expected to know that libtool wants not only nm but
   also flags forcing BSD-format output.  Worse yet, one such "user" is
   the top-level Cygnus configure script, which neither tests for
   nor specifies any BSD-format flags.  So platforms needing BSD-format
   flags always fail to set them when run in a Cygnus tree, breaking
   -export-symbols-regex on such platforms.  Libtool also needs to
   augment $LD on some platforms, but this is done unconditionally,
   augmenting whatever the user specified: the nm check should do the
   same.

   One wrinkle: if the user has overridden $NM, a path might have been
   provided: so we use the user-specified path if there was one, and
   otherwise do the path search as usual.  (If the nm specified doesn't
   work, this might lead to a few extra pointless path searches -- but
   the test is going to fail anyway, so that's not a problem.)

(Tested with NM unset, and set to nm, /usr/bin/nm, my-nm where my-nm is a
symlink to /usr/bin/nm on the PATH, and /not-on-the-path/my-nm where
*that* is a symlink to /usr/bin/nm.)

ChangeLog:

	* libtool.m4 (LT_PATH_NM): Try BSDization flags with a user-provided
	NM, if there is one.  Run nm on itself, not on /dev/null, to avoid
	errors from nms that refuse to work on non-regular files.  Remove
	other workarounds for this problem.  Strip out blank lines from the
	nm output.

If there is a homogeneous struct with float128 members, they should be
copied to vector register save area. The current code incorrectly copies
only the value of the first member, not increasing the pointer with each
iteration. Fix this.

We want the paths to be searched for both shared and archives in order

Recently, mingw-w64 has got updated <msxml.h> from Wine which is included
indirectly by <windows.h> if `WIN32_LEAN_AND_MEAN` is not defined. The
`IXMLDOMDocument` class has a member function named `abort()`, which gets
affected by our `abort()` macro in "system.h".

`WIN32_LEAN_AND_MEAN` should, nevertheless, always be defined. This
can exclude 'APIs such as Cryptography, DDE, RPC, Shell, and Windows
Sockets' [1], and speed up compilation of these files a bit.

Add the patch that fixes i686 Darwin build.

Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>

libffi/ChangeLog:

	* LOCAL_PATCHES: Add patch to fix i686 darwin build.

This addresses a number of issues in the X86 Darwin 32b port for libffi.

1. The pic symbol stubs are weak definitions; the correct section placement
   for these depends on the linker version in use.  We do not have access
   to that information, but we can use the target OS version (assumes that
   the user has installed the latest version of xcode available).
   When a coalesced section is in use (OS versions earlier than Darwin12 /
   OSX 10.8), its name must differ from  __TEXT,__text since otherwise that
   would correspond to altering the attributes of the .text section (which
   produces a diagnostic from the assembler).
   Here we use __TEXT, __textcoal_nt for this which is what GCC emits for
   these stubs.
   For later versions than Darwin 12 (OS X 10.8) we can place the stubs in
   the .text section (if we do not we get a diagnostic from clang -cc1as
   saying that the use of coalesced sections for this is deprecated).

2. The EH frame is specified manually, since there is no support for .cfi_
   directives in 'cctools' assemblers.  The implementation needs to provide
   offsets for CFA advance, code size and to the CIE as signed values
   rather than relocations. However the cctools assembler will produce a
   relocation for expressions like ' .long Lxx-Lyy' which then leads to a
   link-time error.  We correct this by forming the offset values using
   ' .set' directives and then assigning the results of them.

3. The register numbering used by m32 X86 Darwin EH frames is not the same
   as the DWARF debug numbering (the Frame and Stack pointer numbers are
   swapped).

4. The FDE address encoding used by the system tools is '0x10' (PCrel + abs)
   where the value provided was PCrel + sdata4.

5. GCC does not use compact unwind at present, and it was not implemented
   until Darwin10 / OSX 10.6.  There were some issues with function location
   in 10.6 so that the solution here suppresses emitting the compact unwind
   section until Darwin11 / OSX 10.7.

This change adds the configury bits to activate the build of
shared libs on VxWorks ports configured with --enable-shared,
for libraries variants where this is generally supported (rtp,
code model !large - currently not compatible with -fPIC).

Set lt_cv_deplibs_check_method in libtool.m4, so the build of
libraries know how to establish dependencies.  This is useful in
configurations such as aarch64 where proper support of LSE relies
on accurate dependency information between libstdc++ and libgcc_s
to begin with.

Regenerate configure scripts to reflect libtool.m4 change.
