f3b5de944a preprocessor: Adjust C rules on UCNs for C23 [PR117162]
As noted in bug 117162, C23 changed some rules on UCNs to match C++
(this was a late change agreed in the resolution to CD2 comment
US-032, implementing changes from N3124), which we need to implement.

Allow UCNs below 0xa0 outside identifiers for C, with a
pedwarn-if-pedantic before C23 (and a warning with -Wc11-c23-compat)
except for the always-allowed cases of UCNs for $ @ `.  Also as part
of that change, do not allow \u0024 in identifiers as equivalent to $
for C23.

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

	PR c/117162

libcpp/
	* include/cpplib.h (struct cpp_options): Add low_ucns.
	* init.cc (struct lang_flags, lang_defaults): Add low_ucns.
	(cpp_set_lang): Set low_ucns
	* charset.cc (_cpp_valid_ucn): For C, allow UCNs below 0xa0
	outside identifiers, with a pedwarn if pedantic before C23 or a
	warning with -Wc11-c23-compat.  Do not allow \u0024 in identifiers
	for C23.

45ab93d9af non-gcc: Remove trailing whitespace
I've tried to build stage3 with
-Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank
added to STRICT_WARN and that expectably resulted in about
2744 unique trailing whitespace warnings and 124837 leading whitespace
warnings when excluding *.md files (which obviously is in big part a
generator issue).  Others from that are generator related, I think those
need to be solved later.

The following patch just fixes up the easy case (trailing whitespace),
which could be easily automated:
for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ 	]$' | grep -v testsuite/`; do sed -i -e 's/[ 	]*$//' $i; done
I've excluded files which I knew are obviously generated or go FE.

Is there anything else we'd want to avoid the changes?

Due to patch size, I've split it between gcc/ part
and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/;
this part).

e020116db0 c, libcpp: Partially implement C2Y N3353 paper [PR117028]
The following patch partially implements the N3353 paper.
In particular, it adds support for the delimited escape sequences
(\u{123}, \x{123}, \o{123}) which were added already for C++23,
all I had to do is split the delimited escape sequence guarding from
named universal character escape sequence guards
(\N{LATIN CAPITAL LETTER C WITH CARON}), which C++23 has but C2Y doesn't
and emit different diagnostics for C from C++ for the delimited escape
sequences.
And it adds support for the new style of octal literals, 0o137 or 0O1777.
I have so far added that just for C and not C++, because I have no idea
whether C++ will want to handle it similarly.

What the patch doesn't do is any kind of diagnostics for obsoletion of
\137 or 0137, as discussed in the PR, I think it is way too early for that.
Perhaps some non-default warning later on.

libcpp: Support extended characters for #pragma {push,pop}_macro [PR109704]
The implementation of #pragma push_macro and #pragma pop_macro has to date
made use of an ad-hoc function, _cpp_lex_identifier(), which lexes an
identifier out of a string. When support was added for extended characters
in identifiers ($, UCNs, or UTF-8), that support was added only for the
"normal" way of lexing identifiers out of a cpp_buffer (_cpp_lex_direct) and
not for the ad-hoc way. Consequently, extended identifiers are not usable
with these pragmas.

The logic for lexing identifiers has become more complicated than it was
when _cpp_lex_identifier() was written -- it now handles things like \N{}
escapes in C++, for instance -- and it no longer seems practical to maintain
a redundant code path for lexing identifiers. Address the issue by changing
the implementation of #pragma {push,pop}_macro to lex identifiers in the
expected way, i.e. by pushing a cpp_buffer and lexing the identifier from
there.

The existing implementation has some quirks because of the ad-hoc parsing
logic. For example:

 #pragma push_macro("X ")
 ...
 #pragma pop_macro("X")

will not restore macro X (note the extra space in the first string). However:

 #pragma push_macro("X ")
 ...
 #pragma pop_macro("X ")

actually does sucessfully restore "X". This is because the key for looking
up the saved macro on the push stack is the original string passed, so the
string passed to pop_macro needs to match it exactly. It is not that easy to
reproduce this logic in the world of extended characters, given that for
example it should be valid to pass a UCN to push_macro, and the
corresponding UTF-8 to pop_macro. Given that this aspect of the existing
behavior seems unintentional and has no tests (and does not match other
implementations), I opted to make the new logic more straightforward. The
string passed needs to lex to one token, which must be a valid identifier,
or else no action is taken and no error is generated. Any diagnostics
encountered during lexing (e.g., due to a UTF-8 character not permitted to
appear in an identifier) are also suppressed.

It could be nice (for GCC 15) to also add a warning if a pop_macro does not
match a previous push_macro.

c397a8c122 libcpp, genmatch: Use gcc_diag instead of printf for libcpp diagnostics
When working on #embed support, or -Wheader-guard or other recent libcpp
changes, I've been annoyed by the libcpp diagnostics being visually
different from normal gcc diagnostics, especially in the area of quoting
stuff in the diagnostic messages.
Normall GCC diagnostics is gcc_diag/gcc_tdiag, one can use
%</%>, %qs etc. in there, while libcpp diagnostics was marked as printf
and in libcpp we've been very creative with quoting stuff, either
no quotes at all, or "something" quoting, or 'something' quoting, or
`something' quoting (but in none of the cases it used colors consistently
with the rest of the compiler).

Now, libcpp diagnostics is always emitted using a callback,
pfile->cb.diagnostic.  On the gcc/ side, this callback is initialized with
genmatch.cc:  cb->diagnostic = diagnostic_cb;
c-family/c-opts.cc:  cb->diagnostic = c_cpp_diagnostic;
fortran/cpp.cc:  cb->diagnostic = cb_cpp_diagnostic;
where the latter two just use diagnostic_report_diagnostic, so actually
support all the gcc_diag stuff, only the genmatch.cc case didn't.

So, the following patch changes genmatch.cc to use pp_format* instead
of vfprintf so that it supports the gcc_diag formatting (pretty-print.o
unfortunately has various dependencies, so had to link genmatch with
libcommon.a libbacktrace.a and tweak Makefile.in so that there are no
circular dependencies) and marks the libcpp diagnostic routines as
gcc_diag rather than printf.  That change resulted in hundreds of
-Wformat-diag new warnings (most of them useful and resulting IMHO in
better diagnostics), so the rest of the patch is changing the format
strings to make -Wformat-diag happy and adjusting the testsuite for
the differences in how is the diagnostic reformatted.

Dunno if some out of GCC tree projects use libcpp, that case would
make it harder because one couldn't use vfprintf in the diagnostic
callback anymore, but there is always David's libdiagnostic which could
be used for that purpose IMHO.

c5009eb887 libcpp: adjust pedwarn handling
Using cpp_pedwarning (CPP_W_PEDANTIC instead of if (CPP_PEDANTIC cpp_error
lets users suppress these diagnostics with
 #pragma GCC diagnostic ignored "-Wpedantic".

This patch changes all instances of the cpp_error (CPP_DL_PEDWARN to
cpp_pedwarning.  In cases where the extension appears in a later C++
revision, we now condition the warning on the relevant -Wc++??-extensions
flag instead of -Wpedantic; in such cases often the if (CPP_PEDANTIC) check
is retained to preserve the default non-warning behavior.

I didn't attempt to adjust the warning flags for the C compiler, since it
seems to follow a different system than C++.

The CPP_PEDANTIC check is also kept in _cpp_lex_direct to avoid an ICE in
the self-tests from cb.diagnostics not being initialized.

While working on testcases for these changes I noticed that the c-c++-common
tests are not run with -pedantic-errors by default like the gcc.dg and
g++.dg directories are.  And if I specify -pedantic-errors with dg-options,
the default -std= changes from c++?? to gnu++??, which interferes with some
other pedwarns.  So two of the tests are C++-only.

Jakub Jelinek
29341f21ce c++: Implement C++26 P2558R2 - Add @, $, and ` to the basic character set [PR110343]
The following patch implements the easy parts of the paper.
When @$` are added to the basic character set, it means that
R"@$`()@$`" should now be valid (here I've noticed most of the
raw string tests were tested solely with -std=c++11 or -std=gnu++11
and I've tried to change that), and on the other side even if
by extension $ is allowed in identifiers, \u0024 or \U00000024
or \u{24} should not be, similarly how \u0041 is not allowed.

The paper in 3.1 claims though that
 #include <stdio.h>

 #define STR(x) #x

int main()
{
  printf("%s", STR(\u0060)); // U+0060 is ` GRAVE ACCENT
}
should have been accepted before this paper (and rejected after it),
but g++ rejects it.

I've tried to understand it, but am confused on what is the right
behavior and why.

Consider
 #define STR(x) #x
const char *a = "\u00b7";
const char *b = STR(\u00b7);
const char *c = "\u0041";
const char *d = STR(\u0041);
const char *e = STR(a\u00b7);
const char *f = STR(a\u0041);
const char *g = STR(a \u00b7);
const char *h = STR(a \u0041);
const char *i = "\u066d";
const char *j = STR(\u066d);
const char *k = "\u0040";
const char *l = STR(\u0040);
const char *m = STR(a\u066d);
const char *n = STR(a\u0040);
const char *o = STR(a \u066d);
const char *p = STR(a \u0040);

Neither clang nor gcc emit any diagnostics on the a, c, i and k
initializers, those are certainly valid (c is invalid in C23 though).  g++
emits with -pedantic-errors errors on all the others, while clang++ on the
ones with STR involving \u0041, \u0040 and a\u0066d.  The chosen values are
\u0040 '@' as something being changed by this paper, \u0041 'A' as basic
character set char valid in identifiers before/after, \u00b7 as an example
of character which is pedantically valid in identifiers if not at the start
and \u066d s something pedantically not valid in identifiers.

Now, https://eel.is/c++draft/lex.charset#6 says that UCN used outside of a
string/character literal which corresponds to basic character set character
(or control character) is ill-formed, that would make d, f, h cases invalid
for C++ and l, n, p cases invalid for C++26.

https://eel.is/c++draft/lex.name states which characters can appear at the
start of the identifier and which can appear after the start.  And
https://eel.is/c++draft/lex.pptoken states that preprocessing-token is
either identifier, or tons of other things, or "each non-whitespace
character that cannot be one of the above"

Then https://eel.is/c++draft/lex.pptoken#1 says that this last category is
invalid if the preprocessing token is being converted into token.

And https://eel.is/c++draft/lex.pptoken#2 includes "If any character not in
the basic character set matches the last category, the program is
ill-formed."

Now, e.g.  for the C++23 STR(\u0040) case, \u0040 is there not in the basic
character set, so valid outside of the literals (not the case anymore in
C++26), but it isn't nondigit and doesn't have XID_Start property, so it
isn't IMHO an identifier and so must be the "each non-whitespace character
that cannot be one of the above" case.  Why doesn't the above mentioned
https://eel.is/c++draft/lex.pptoken#2 sentence make that invalid?  Ignoring
that, I'd say it would be then stringized and that feels like it is what
clang++ is doing.  Now, e.g.  for the STR(a\u066d) case, I wonder why that
isn't lexed as a identifier followed by \u066d "each non-whitespace
character that cannot be one of the above" token and stringified similarly,
clang++ rejects that.

What GCC libcpp seems to be doing is that if that forms_identifier_p calls
_cpp_valid_utf8 or _cpp_valid_ucn with an argument which tells it is first
or second+ in identifier, and e.g.  _cpp_valid_ucn then for UCNs valid in
string literals calls
  else if (identifier_pos)
    {
      int validity = ucn_valid_in_identifier (pfile, result, nst);

      if (validity == 0)
        cpp_error (pfile, CPP_DL_ERROR,
                   "universal character %.*s is not valid in an identifier",
                   (int) (str - base), base);
      else if (validity == 2 && identifier_pos == 1)
        cpp_error (pfile, CPP_DL_ERROR,
   "universal character %.*s is not valid at the start of an identifier",
                   (int) (str - base), base);
    }
so basically all those invalid in identifiers cases emit an error and
pretend to be valid in identifiers, rather than what e.g.  _cpp_valid_utf8
does for C but not for C++ and only for the chars completely invalid in
identifiers rather than just valid in identifiers but not at the start:
          /* In C++, this is an error for invalid character in an identifier
             because logically, the UTF-8 was converted to a UCN during
             translation phase 1 (even though we don't physically do it that
             way).  In C, this byte rather becomes grammatically a separate
             token.  */

          if (CPP_OPTION (pfile, cplusplus))
            cpp_error (pfile, CPP_DL_ERROR,
                       "extended character %.*s is not valid in an identifier",

            }
The comment doesn't really match what is done in recent C++ versions because
there UCNs are translated to characters and not the other way around.

194825f206 c++: Implement C++26 P1854R4 - Making non-encodable string literals 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.

1c58566450 c++: Implement C++26 P2361R6 - Unevaluated strings [PR110342]
The following patch implements C++26 unevaluated-string.
As it seems to me just extra pedanticity, it is implemented only for
-std=c++26 or -std=gnu++26 and later and only if -pedantic/-pedantic-errors.
Nothing is done for inline asm, while the spec changes those, it changes it
to a balanced token sequence with implementation defined rules on what is
and isn't allowed (so pedantically accepting asm ("" : "+m" (x));
was accepts-invalid before C++26, but we didn't diagnose anything).
For the other spots mentioned in the paper, static_assert message,
linkage specification, deprecated/nodiscard attributes it enforces the
requirements (no prefixes, udlit suffixes, no octal/hexadecimal escapes
(conditional escape sequences were rejected with pedantic already before).
For the deprecated operator "" identifier case I've kept things as is,
because everything seems to have been diagnosed already (a lot being implied
from the string having to be empty).

4f01ae3761 diagnostics: add support for "text art" diagrams
Existing text output in GCC has to be implemented by writing
sequentially to a pretty_printer instance.  This makes it
hard to implement some kinds of diagnostic output (see e.g.
diagnostic-show-locus.cc).

This patch adds more flexible ways of creating text output:
- a canvas class, which can be "painted" to via random-access (rather
that sequentially)
- a table class for 2D grid layout, supporting items that span
multiple rows/columns
- a widget class for organizing diagrams hierarchically.

The patch also expands GCC's diagnostics subsystem so that diagnostics
can have "text art" diagrams - think ASCII art, but potentially
including some Unicode characters, such as box-drawing chars.

The new code is in a new "gcc/text-art" subdirectory and "text_art"
namespace.

The patch adds a new "-fdiagnostics-text-art-charset=VAL" option, with
values:
- "none": don't emit diagrams (added to -fdiagnostics-plain-output)
- "ascii": use pure ASCII in diagrams
- "unicode": allow for conservative use of unicode drawing characters
(such as box-drawing characters).
- "emoji" (the default): as "unicode", but potentially allow for
conservative use of emoji in the output (such as U+26A0 WARNING SIGN).
I made it possible to disable emoji separately from unicode as I believe
there's a generation gap in acceptance of these characters (some older
programmers have a visceral reaction against them, whereas younger
programmers may have no problem with them).

Diagrams are emitted to stderr by default.  With SARIF output they are
captured as a location in "relatedLocations", with the diagram as a
code block in Markdown within a "markdown" property of a message.

This patch doesn't add any such diagram usage to GCC, saving that for
followups, apart from adding a plugin to the test suite to exercise the
functionality.

d495ea2b23 diagnostics: ensure that .sarif files are UTF-8 encoded [PR109098]
PR analyzer/109098 notes that the SARIF spec mandates that .sarif
files are UTF-8 encoded, but -fdiagnostics-format=sarif-file naively
assumes that the source files are UTF-8 encoded when quoting source
artefacts in the .sarif output, which can lead to us writing out
.sarif files with non-UTF-8 bytes in them (which break my reporting
scripts).

The root cause is that sarif_builder::maybe_make_artifact_content_object
was using maybe_read_file to load the file content as bytes, and
assuming they were UTF-8 encoded.

This patch reworks both overloads of this function (one used for the
whole file, the other for snippets of quoted lines) so that they go
through input.cc's file cache, which attempts to decode the input files
according to the input charset, and then encode as UTF-8.  They also
check that the result actually is UTF-8, for cases where the input
charset is missing, or incorrectly specified, and omit the quoted
source for such awkward cases.

Doing so fixes all of the cases I've encountered.

The patch adds a new:
  { dg-final { verify-sarif-file } }
directive to all SARIF test cases in the test suite, which verifies
that the output is UTF-8 encoded, and is valid JSON.  In particular
it verifies that when we complain about encoding problems, the .sarif
report we emit is itself correctly encoded.

36d20fa4a8 preprocessor: C2x identifier rules
C2x has, like C++, adopted rules for identifiers based directly on an
unversioned normative reference to Unicode.  Make libcpp follow those
rules for c2x / gnu2x standards (this involves bringing back a flag
separate from the C++ one for whether to use these identifier rules,
but this time enabled for all C++ language versions since that was the
conclusion adopted for C++ identifier handling).

There is one change here that affects C++.  I believe the new
normative requirement for NFC only applies to identifiers, not to the
use of identifier-continue characters in pp-numbers, where there is no
such requirement and so the diagnostic ought to be a warning not a
pedwarn in pp-numbers, and that this is the case for both C and C++.

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

The following patch changes this, so that:
1) outside of string/character literals, \N without following { is never
   treated as an error nor warning, it is silently treated as \ separate
   token followed by whatever is after it
2) \u{123} and \N{LATIN SMALL LETTER A WITH ACUTE} are not handled as
   extension at all outside of string/character literals in the strict
   standard modes (-std=c*) except for -std=c++{23,2b}, only in the
   -std=gnu* modes, because it changes behavior on valid sources, e.g.
   #define z(x) 0
   #define a z(
   int x = a\u{123});
   int y = a\N{LATIN SMALL LETTER A WITH ACUTE});
3) introduces -Wunicode warning (on by default) and warns for cases
   of what looks like invalid delimited escape sequence or named

0b8c57ed40 libcpp: Add -Winvalid-utf8 warning [PR106655]
The following patch introduces a new warning - -Winvalid-utf8 similarly
to what clang now has - to diagnose invalid UTF-8 byte sequences in
comments, but not just in those, but also in string/character literals
and outside of them.

The warning is on by default when explicit -finput-charset=UTF-8 is
used and C++23 compilation is requested and if -{,W}pedantic or
-pedantic-errors it is actually a pedwarn.

The reason it is on by default only for -finput-charset=UTF-8 is
that the sources often are UTF-8, but sometimes could be some ASCII
compatible single byte encoding where non-ASCII characters only
appear in comments.  So having the warning off by default
is IMO desirable.  The C++23 pedantic mode for when the source code
is UTF-8 is -std=c++23 -pedantic-errors -finput-charset=UTF-8.

eb4879ab90 c++: Implement C++23 P2071R2 - Named universal character escapes [PR106648]
The following patch implements the
C++23 P2071R2 - Named universal character escapes
paper to support \N{LATIN SMALL LETTER E} etc.
I've used Unicode 14.0, there are 144803 character name properties
(including the ones generated by Unicode NR1 and NR2 rules)
and correction/control/alternate aliases, together with zero terminators
that would be 3884745 bytes, which is clearly unacceptable for libcpp.
This patch instead contains a generator which from the UnicodeData.txt
and NameAliases.txt files emits a space optimized radix tree (208765
bytes long for 14.0), a single string literal dictionary (59418 bytes),
maximum name length (currently 88 chars) and two small helper arrays
for the NR1/NR2 name generation.
The radix tree needs 2 to 9 bytes per node, the exact format is
described in the generator program.  There could be ways to shrink
the dictionary size somewhat at the expense of slightly slower lookups.

Currently the patch implements strict matching (that is what is needed
to actually implement it on valid code) and Unicode UAX44-LM2 algorithm
loose matching to provide hints (that algorithm essentially ignores
hyphens in between two alphanumeric characters, spaces and underscores
(with one exception for hyphen) and does case insensitive matching).
In the attachment is a WIP patch that shows how to implement also
spellcheck.{h,cc} style discovery of misspellings, but I'll need to talk
to David Malcolm about it, as spellcheck.{h,cc} is in gcc/ subdir
(so the WIP incremental patch instead prints all the names to stderr).

053876cdbe preprocessor/106426: Treat u8 character literals as unsigned in char8_t modes.
This patch corrects handling of UTF-8 character literals in preprocessing
directives so that they are treated as unsigned types in char8_t enabled
C++ modes (C++17 with -fchar8_t or C++20 without -fno-char8_t). Previously,
UTF-8 character literals were always treated as having the same type as
ordinary character literals (signed or unsigned dependent on target or use
of the -fsigned-char or -funsigned char options).
