update-copyright.py --this-year FAILs on two spots in the modula2
directories.
One is gpl_v3_without_node.texi, I think that is similar to other
license files which we already exclude from updates.
And the other is GmcOptions.cc, which has lines like
  mcPrintf_printf0 ((const char *) "Copyright ", 10);
  mcPrintf_printf1 ((const char *) "Copyright (C) %d Free Software Foundation, Inc.\\n", 49, (const unsigned char *) &year, (sizeof (year)-1));
  mcPrintf_printf1 ((const char *) "Copyright (C) %d Free Software Foundation, Inc.\\n", 49, (const unsigned char *) &year, (sizeof (year)-1));
which update-copyhright.py obviously can't grok.  The file is generated
and doesn't contain normal Copyright year which should be updated, so I think
it is also ok to skip it.

	* update-copyright.py (GenericFilter): Skip gpl_v3_without_node.texi.

When compare_tests compares both C and C++ tests in c-c++-common, they
get the same identifier, so expected differences in results across
languages become undesirably noisy.

This patch adds tool identifiers to tests, so that runs by different
tools are not confused by the compare logic.

It also fixes a bug in reporting differences, that would attempt to
print an undefined fname (the definitions are in subshell loops), and
adjusts the target insertion to match tabs in addition to blanks after
colons.

	blanks to insert tool and target.  Don't print undefined fname.

When I tried to use config-list.mk, the build for every triple except
the build machine's failed for m2.  This is because, unlike other
languages, m2 builds target objects during all-gcc.  The build will
therefore fail unless you have access to an appropriate binutils
(or an equivalent).  That's quite a big ask for over 100 targets. :)

This patch therefore makes m2 an optional inclusion.

Doing that wasn't entirely straightforward though.  The current
configure line includes "--enable-languages=all,...", which means
that the "..." can only force languages to be added that otherwise
wouldn't have been.  (I.e. the only effect of the "..." is to
override configure autodetection.)

The choice of all,ada and:

  # Make sure you have a recent enough gcc (with ada support) in your path so
  # that --enable-werror-always will work.

make it clear that lack of GNAT should be a build failure rather than
silently ignored.  This predates the D frontend, which requires GDC
in the same way that Ada requires GNAT.  I don't know of a reason
why D should be treated differently.

The patch therefore expands the "all" into a specific list of
languages.

That in turn meant that Fortran had to be handled specially,
since bpf and mmix don't support Fortran.

Perhaps there's an argument that m2 shouldn't build target objects
during all-gcc, but (a) it works for practical usage and (b) the
patch is an easy workaround.  I'd be happy for the patch to be
reverted if the build system changes.

contrib/
	* config-list.mk (OPT_IN_LANGUAGES): New variable.
	($(LIST)): Replace --enable-languages=all with a specifc list.
	Disable fortran on bpf and mmix.  Enable the languages in
	OPT_IN_LANGUAGES.

Tests with keys that match both PASS, FAIL (or now
optionally XPASS), count as fail.  XPASSes were previously
ignored.  Handling them as FAIL seems the most useful
alternative, but not counting XPASSes may be deliberate.
It's also a matter of compatibility, so make it optional.

Attempts to use --handle-xpass-as-fail was previously
flagged as a usage error.  If you pass it now, on state with
previous mixed XPASS and PASS results but doesn't change in
this run, the XPASS is discovered as a (new) regression.
For new XPASSing tests, it's handled as a new FAIL.

	* btest-gcc.sh (--handle-xpass-as-fail): New option.

	* btest-gcc.sh (Option handling): Break out shifts from each
	option alternative.

This is a long-standing bug: passing "-j --add-passes-despite-regression"
or "--add-passes-despite-regression -j" caused the second option to be
treated as TARGET; the first non-option parameter.

	* btest-gcc.sh (Option handling): Handle multiple options.

The following patch (in plaintext just a pseudo-patch where I've left out
the too big parts of either wget downloaded or regenerated files out with

we are using, but from the other files it is clear what should have been
added; I've filed a bugreport against Unicode.

This patch updates gettext.m4 and related .m4 files and adds
gettext-runtime as a gmp/mpfr/... style host library, allowing newer
libintl to be used.

This patch /does not/ add build-time tools required for
internationalizing (msgfmt et al), instead, it just updates the runtime
library.  The result should be a distribution that acts exactly the same
when a copy of gettext is present, and disables internationalization
otherwise.

There should be no changes in behavior when gettext is included in-tree.
When gettext is not included in tree, nor available on the system, the
programs will be built without localization.

	PR bootstrap/12596

Hello all,

this patch checks in mdcompact, the tool written in elisp that I used
to mass convert all the multi choice pattern in the aarch64 back-end to
the new compact syntax.

I tested it on Emacs 29 (might run on older versions as well not
sure), also I verified it runs cleanly on a few other back-ends (arm,
loongarch).

The tool can be used to convert a single pattern, an open buffer or
all md files in a directory.

The tool might need further adjustment to run on some specific
back-end, in case very happy to help.

This patch was pre-approved here [1].

Best Regards

  Andrea Corallo

The testing infrastructure built by Martin Liška contains checking a
few python scripts in contrib witha tool flake8.  That tool recently
complains that:

  contrib/mklog.py:360:45: E711 comparison to None should be 'if cond is None:'
  contrib/mklog.py:362:1: E305 expected 2 blank lines after class or function definition, found 1

I'd like to silence these with the following, hopefully trivial,
changes.  However, I have only tested the changes by running flake8
again and running ./contrib/mklog.py --help.

Is this good for trunk?  (Or should I stop using flake8 instead?)

Thanks,

Martin

    The header of the python version looked like:

    After this change both headers look like:

The following commit should have enabled checking for invalid revert hashes;
it worked locally - but did work as pre-commit hook on sourceware
as it wasn't copied to the hook directory:
r14-3777-gff20bce9f58 contrib/gcc-changelog: Check whether revert-commit exists

Hence, the following revert commit was wrongly applied:
r14-3778-gfbbd9001e9b Revert "contrib/gcc-changelog: Check whether revert-commit exists"
(In this commit: contrib/ChangeLog update for the revert.)

r14-3779-g69e83181ebc contrib/gcc-changelog: Check whether revert-commit exists
Re-applied the commit with a commit-log typo fixed but missing a late commit.

r14-3780-g1b0934b7276 Revert "contrib/gcc-changelog: Check whether revert-commit exists"
This commit still came through but re-instated the late wording fix in
contrib/gcc-changelog/git_commit.py.
(In this commit: contrib/ChangeLog update for the wording change.)

r14-3781-gd22cd7745ff Revert: "Another revert test with a bogus hash"
Another attempt to get a reject, but it still came through.
It removed tailing whitespace in libgomp/target.c
(In this commit: libgomp/ChangeLog was for the whitespace removal.)
