Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).
This patch updates GCC to use autoconf 2.69 and automake 1.15.1.
(That's not the latest automake version, but it's the one used by
binutils-gdb, with which consistency is desirable, and in any case
seems a useful incremental update that should make a future update to
1.16.1 easier.)
The changes are generally similar to the binutils-gdb ones, and are
copied from there where shared files and directories are involved
(there are some further changes to such shared directories, however,
which I'd expect to apply to binutils-gdb once this patch is in GCC).
Largely, obsolete AC_PREREQ calls are removed, while many
AC_LANG_SOURCE calls are added to avoid warnings from aclocal and
autoconf. Multilib support is no longer included in core automake,
meaning that multilib.am needs copying from automake's contrib
directory into the GCC source tree. Autoconf 2.69 has Go support, so
local copies of that support are removed. I hope the D support will
soon be submitted to upstream autoconf so the local copy of that can
be removed in a future update. Changes to how automake generates
runtest calls mean quotes are removed from RUNTEST definitions in five
lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm,
libphobos, libvtv; some others have RUNTEST definitions without
quotes, which are still OK); libgo and libphobos also get
-Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST
do not generate automake warnings.
Note that the regeneration did not include regeneration of
fixincludes/config.h.in (attempting such regeneration resulted in all
the USED_FOR_TARGET conditionals disappearing; and I don't see
anything in the fixincludes/ directory that would result in such
conditionals being generated, unlike in the gcc/ directory). Also
note that libvtv/testsuite/other-tests/Makefile.in was not
regenerated; that directory is not listed as a subdirectory for which
Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm
not sure how it's meant to be regenerated.
While I mostly fixed warnings should running aclocal / automake /
autoconf, there were various such warnings from automake in the
libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos
directories that I did not fix, preferring to leave those to the
relevant subsystem maintainers. Specifically, most of those warnings
were of the following form (example from libgfortran):
Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory,
Makefile.am:48: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they
will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
I think it's best for the relevant maintainers to add subdir-objects
and do any other associated Makefile.am changes needed. In some cases
the paths in the warnings involved ../; I don't know if that adds any
extra complications to the use of subdir-objects.
I've tested this with native, cross and Canadian cross builds. The
risk of any OS-specific issues should I hope be rather lower than if a
libtool upgrade were included (we *should* do such an upgrade at some
point, but it's more complicated - it involves identifying all our
local libtool changes to see if any aren't included in the upstream
version we update to, and reverting an upstream libtool patch that's
inappropriate for use in GCC); I think it would be better to get this
update into GCC so that people can test in different configurations
and we can fix any issues found, rather than to try to get more and
more testing done before it goes in.

PR libstdc++/87822 fix layout change for nested std::pair
The introduction of the empty __pair_base base class for PR 86751
changed the layout of std::pair<std::pair<...>, ...>. The outer pair and
its first member both have a base class of the same type, which cannot
exist at the same address. This causes the first member to be at a
non-zero offset.
The solution is to make the base class depend on the template
parameters, so that each pair type has a different base class type,
which allows the base classes of the outer pair and its first member to
have the same address.

to update the _M_Nb member after using it as an index.

Don't allow the pool allocator to be configured to allocate zero-sized objects

memory corruption when the assumed size turned out to be different to

Fix ICE in get_substring_ranges_for_loc on __FILE__ (PR c++/87721)
PR c++/87721 reports a crash in get_substring_ranges_for_loc introduced
by r265271, my fix for PR 87562.
The new issue occurs when attempting to get a location with a string
literal inside a macro in which the first token is __FILE__ (formed via
concatenation). Attempting to get the spelling location of __FILE__
fails, leading to NULL for start_ord_map and final_ord_map, and thus
a NULL pointer dereference.
Given that our "on-demand" substring locations approach reparses the
string literals, there isn't a good way to access the locations inside
such string literals: attempting to reparse __FILE__ fails with a
"missing open quote".
This patch applies the easy fix by gracefully rejecting the case where
the spelling locations for the start or finish give us NULL maps.

C++: simplify output from suggest_alternatives_for
In the C++ FE, after emitting various errors about unrecognized names,
the parser can call
suggest_alternatives_for
and/or
suggest_alternative_in_explicit_scope.
These can issue zero or more suggestions for the unrecognized name,
or various other "note" diagnostics suggesting how to fix the problem.
For example, currently g++ emits:
t.cc:12:3: error: 'gtk_widget_showall' was not declared in this scope
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
t.cc:12:3: note: suggested alternative: 'gtk_widget_show_all'
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
| gtk_widget_show_all
This patch consolidates the common case when there is a single
candidate, so that the error can issue a fix-it hint directly.
This simplifies the above to:
t.cc:12:3: error: 'gtk_widget_showall' was not declared in this scope;
did you mean 'gtk_widget_show_all'?
12 | gtk_widget_showall (w);
| ^~~~~~~~~~~~~~~~~~
| gtk_widget_show_all
omitting the second "note" diagnostic.
Doing so requires changing the above "suggest_" functions so that
rather than being called after "error" and emitting a note directly,
they are called before the "error", and return a name_hint, which
can contain a suggestion and/or a deferred diagnostic. The "single
candidate" case is handled via a suggestion, and the "multiple
candidates" case via a new subclass of deferred_diagnostic.
There was some complication due to the fact that we don't always have
enough location information to issue a fix-it hint. Specifically,
for the case in qualified_name_lookup_error, the location is that of
the name, but the location of the qualifier prefix isn't reliably
available. For some hints, e.g. spell-corrections, the replacement
is of the name, and for others, e.g. parent namespaces, it's for the
qualified name. The patch addresses this by splitting this case out
into a new "suggest_alternatives_in_other_namespaces" function, for
which fix-it hints aren't issued.
Another complication is that of emitting a note when
--param cxx-max-namespaces-for-diagnostic-help
is reached. The patch emulates the existing behavior by emitting
the note from a deferred_diagnostic. This potentially needs to
co-exist with another deferred_diagnostic, so it works as a decorator
around any other such deferred_diagnostic. Doing so requires slightly
extending class name_hint.
On adding test coverage for the various cases, I discovered that
after emitting a "FOO is not a namespace-name" error, we also emit
a "expected namespace-name before" error. The patch removes this
second error for the case where it's redundant, simplifying this case
from e.g.:
spellcheck-ns.C:10:24: error: 'inner_ms' is not a namespace-name
10 | using namespace outer::inner_ms;
| ^~~~~~~~
spellcheck-ns.C:10:24: note: suggested alternative: 'inner_ns'
10 | using namespace outer::inner_ms;
| ^~~~~~~~
| inner_ns
spellcheck-ns.C:10:32: error: expected namespace-name before ';' token
10 | using namespace outer::inner_ms;
| ^
to:
spellcheck-ns.C:10:24: error: 'inner_ms' is not a namespace-name;
did you mean 'inner_ns'?
10 | using namespace outer::inner_ms;
| ^~~~~~~~
| inner_ns

Folding and check_function_arguments
This patch eliminates the arglocs array I introduced to build_over_call
in r264887, and eliminates the call to maybe_constant_value when building
"fargs" (thus retaining location wrapper nodes).
Instead, this patch requires that any checks within
check_function_arguments that need folded arguments do their own folding.
Of the various checks:
(a) check_function_nonnull already calls fold_for_warn,
(b) check_function_format doesn't need folding
(c) check_function_sentinel needs fold_for_warn in one place, which the
patch adds, and
(d) check_function_restrict needs per-argument folding, which the patch
adds. Given that it scans before and after resetting TREE_VISITED on
each argument, it seemed best to make a copy of the array, folding each
argument from the outset, rather than repeatedly calling fold_for_warn;
gcc/c-family/ChangeLog:
PR c++/56856
* c-common.c (check_function_sentinel): Call fold_for_warn on the
argument.
(check_function_restrict): Rename param "argarray" to
"unfolded_argarray", and make a copy named "argarray", calling
fold_for_warn on each argument.
(check_function_arguments): Add note about responsibility for
folding the arguments.

[rs6000] Consistently use '__vector' instead of 'vector'
Revision r265535 committed changes that used 'vector' instead of the
preferred '__vector'. There is a reason that '__vector' is preferred,
because it ensures no conflicts with C++ namespace. Indeed,
gcc/config/rs6000/xmmintrin.h undefines it, leading to errors:
gcc/include/xmmintrin.h:999:20: error: 'vector' undeclared (first use in this function); did you mean 'vec_or'?
