The PR shows that we ICE after lexing an invalid unterminated raw string,

When adding validation of .sarif files against the schema
(PR testsuite/109360) I discovered various issues where we were
generating invalid .sarif files.
Specifically, in
c-c++-common/diagnostic-format-sarif-file-bad-utf8-pr109098-1.c
the relatedLocations for the "note" diagnostics were missing column
numbers, leading to validation failure due to non-unique elements,
such as multiple:
"message": {"text": "invalid UTF-8 character <bf>"}},
on line 25 with no column information.
Root cause is that for some diagnostics in libcpp we have a location_t
representing the line as a whole, setting a column_override on the
rich_location (since the line hasn't been fully read yet). We were
handling this column override for plain text output, but not for .sarif
output.
Similarly, in diagnostic-format-sarif-file-pr111700.c there is a warning
emitted on "line 0" of the file, whereas SARIF requires line numbers to
be positive.
We also use column == 0 internally to mean "the line as a whole",
whereas SARIF required column numbers to be positive.
This patch fixes these various issues.

When the file name for a #include directive is the result of stringifying a
macro argument, libcpp needs to take some care to get the whitespace
correct; in particular stringify_arg() needs to see a CPP_PADDING token
between macro tokens so that it can figure out when to output space between
tokens. The CPP_PADDING tokens are not normally generated when handling a
preprocessor directive, but for #include-like directives, libcpp sets the
state variable pfile->state.directive_wants_padding to TRUE so that the
CPP_PADDING tokens will be output, and then everything works fine for
computed includes.
As the PR points out, things do not work fine for __has_include. Fix that by
setting the state variable the same as is done for #include.

In libcpp/files.cc, the function _cpp_has_header(), which implements
__has_include and __has_include_next, does not check for a NULL return value
from search_path_head(), leading to an ICE tripping an assert when
_cpp_find_file() tries to use it. Fix it by checking for that case and
silently returning false instead.
As suggested by the PR author, it is easiest to make a testcase by using
the -idirafter option. To enable that, also modify the dg-additional-options
testsuite procedure to make the global $srcdir available, since -idirafter
requires the full path.

changes in -std=c11 etc. modes [PR114007]
We aren't able to parse __has_attribute (vendor::attr) (and __has_c_attribute
and __has_cpp_attribute) in strict C < C23 modes. While in -std=gnu* modes
or in -std=c23 there is CPP_SCOPE token, in -std=c* (except for -std=c23)
there are is just a pair of CPP_COLON tokens.
The c-lex.cc hunk adds support for that.
That leads to a question if we should return 1 or 0 from
__has_attribute (gnu::unused) or not, because while
[[gnu::unused]] is parsed fine in -std=gnu*/-std=c23 modes (sure, with
pedwarn for < C23), we do not parse it at all in -std=c* (except for
-std=c23), we only parse [[__extension__ gnu::unused]] there. While
the __extension__ in there helps to avoid the pedwarn, I think it is
better to be consistent between GNU and strict C < C23 modes and
parse [[gnu::unused]] too; on the other side, I think parsing
[[__extension__ gnu : : unused]] is too weird and undesirable.
So, the following patch adds a flag during preprocessing at the point
where we normally create CPP_SCOPE tokens out of 2 consecutive colons
on the first CPP_COLON to mark the consecutive case (as we are tight
on the bits, I've reused the PURE_ZERO flag, which is used just by the
C++ FE and only ever set (both C and C++) on CPP_NUMBER tokens, this
new flag has the same value and is only ever used on CPP_COLON tokens)
and instead of checking loose_scope_p argument (i.e. whether it is
[[__extension__ ...]] or not), it just parses CPP_SCOPE or CPP_COLON
with CLONE_SCOPE flag followed by another CPP_COLON the same.
The latter will never appear in >= C23 or -std=gnu* modes, though
guarding its use say with flag_iso && !flag_isoc23 && doesn't really
work because the __extension__ case temporarily clears flag_iso flag.
This makes the -std=c11 etc. behavior more similar to -std=gnu11 or
-std=c23, the only difference I'm aware of are the
#define JOIN2(A, B) A##B
[[vendor JOIN2(:,:) attr]]
[[__extension__ vendor JOIN2(:,:) attr]]
cases, which are accepted in the latter modes, but results in error
in -std=c11; but the error is during preprocessing that :: doesn't
form a valid preprocessing token, which is true, so just don't do that if
you try to have __STRICT_ANSI__ && __STDC_VERSION__ <= 201710L
compatibility.

libcpp currently lacks the infrastructure to assign correct locations to
macros that were defined prior to loading a PCH and then restored
afterwards. While I plan to address that fully for GCC 15, this patch
improves things by using at least a valid location, even if it's not the
best one. Without this change, libcpp uses pfile->directive_line as the
location for the restored macros, but this location_t applies to the old
line map, not the one that was just restored from the PCH, so the resulting
location is unpredictable and depends on what was stored in the line maps
before. With this change, all restored macros get assigned locations at the
line of the #include that triggered the PCH restore. A future patch will
store the actual file name and line number of each definition and then
synthesize locations in the new line map pointing to the right place.

error. The problem is that _cpp_lex_direct can leave result->src_loc
uninitialized in some cases and later on we use that location_t.
_cpp_lex_direct essentially does:
cppchar_t c;
...
cpp_token *result = pfile->cur_token++;
fresh_line:
result->flags = 0;
...
if (buffer->need_line)
{
if (pfile->state.in_deferred_pragma)
{
result->type = CPP_PRAGMA_EOL;
... // keeps result->src_loc uninitialized;
return result;
}
if (!_cpp_get_fresh_line (pfile))
{
result->type = CPP_EOF;
if (!pfile->state.in_directive && !pfile->state.parsing_args)
{
result->src_loc = pfile->line_table->highest_line;
...
}
... // otherwise result->src_loc is sometimes uninitialized here
return result;
}
...
}
...
result->src_loc = pfile->line_table->highest_line;
...
c = *buffer->cur++;
switch (c)
{
...
case '\n':
...
buffer->need_line = true;
if (pfile->state.in_deferred_pragma)
{
result->type = CPP_PRAGMA_EOL;
...
return result;
}
goto fresh_line;
...
}
...
So, if _cpp_lex_direct is called without buffer->need_line initially set,
result->src_loc is always initialized (and actually hundreds of tests rely
on that exact value it has), even when c == '\n' and we set that flag later
on and goto fresh_line. For CPP_PRAGMA_EOL case we have in that case
separate handling and don't goto.
But if _cpp_lex_direct is called with buffer->need_line initially set and
either decide to return a CPP_PRAGMA_EOL token or if getting a new line fails
for some reason and we return an CPP_ERROR token and we are in directive
or parsing args state, it is kept uninitialized and can be whatever the
allocation left it there as.
The following patch attempts to keep the status quo, use value that was
returned previously if it was initialized (i.e. we went through the
goto fresh_line; statement in c == '\n' handling) and only initialize
result->src_loc if it was uninitialized before.

When libcpp encounters a divide by zero while processing a constant
expression "x/y", it returns "x" as a fallback. The value of the fallback is
not normally important, since an error will be generated anyway, but if the
expression appears in an unevaluated context, such as "0 ? 0/0u : -1", then
there will be no error, and the fallback value will be meaningful to the
extent that it may cause promotion from signed to unsigned of an operand
encountered later. As the PR notes, libcpp does not do the unsigned
promotion correctly in this case; fix it by making the fallback return value
unsigned as necessary.

This patch implements clang's __has_feature and __has_extension in GCC.
Currently the patch aims to implement all documented features (and some
undocumented ones) following the documentation at
https://clang.llvm.org/docs/LanguageExtensions.html with the exception
of the legacy features for C++ type traits. These are omitted, since as
the clang documentation notes, __has_builtin is the correct "modern" way
to query for these (which GCC already implements).

ill-formed [PR110341]
This paper voted in as DR makes some multi-character literals ill-formed.
'abcd' stays valid, but e.g. 'á' is newly invalid in UTF-8 exec charset
while valid e.g. in ISO-8859-1, because it is a single character which needs
2 bytes to be encoded.
The following patch does that by checking (only pedantically, especially
because it is a DR) if we'd emit a -Wmultichar warning because character
constant has more than one byte in it whether the number of source characters
is equal to the number of bytes in the multichar string.
If it is, it is normal multi-character literal constant
and is diagnosed normally with -Wmultichar, otherwise at least one of the
c-chars in the sequence was encoded as 2+ bytes.

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.
ChangeLog:
