c4d6dcacfc libcpp: Implement C++23 P1949R7 - C++ Identifier Syntax using Unicode Standard Annex 31 
The following patch implements the
P1949R7 - C++ Identifier Syntax using Unicode Standard Annex 31
paper.  We already allow UTF-8 characters in the source, so that part
is already implemented, so IMHO all we need to do is pedwarn instead of
just warn for the (default) -Wnormalize=nfc (or for -Wnormalize={id,nkfc})
if the character is not in NFC and to use the unicode XID_Start and
XID_Continue derived code properties to find out what characters are allowed
(the standard actually adds U+005F to XID_Start, but we are handling the
ASCII compatible characters differently already and they aren't allowed
in UCNs in identifiers).  Instead of hardcoding the large tables
in ucnid.tab, this patch makes makeucnid.c read them from the Unicode
tables (13.0.0 version at this point).

For non-pedantic mode, we accept as 2nd+ char in identifiers a union
of valid characters in all supported modes, but for the 1st char it
was actually pedantically requiring that it is not any of the characters
that may not appear in the currently chosen standard as the first character.
This patch changes it such that also what is allowed at the start of an
identifier is a union of characters valid at the start of an identifier
in any of the pedantic modes.

1a9b3f04c1 c: Add support for __FILE_NAME__ macro (PR c/42579) 
The toolchain provided by ST for stm32 has had support for
__FILENAME__ for a while, but clang/llvm has recently implemented
support for __FILE_NAME__, so it seems better to use the same macro
name in GCC.

It happens that the ST patch is similar to the one proposed in PR
c/42579.

Given these input files:
::::::::::::::
mydir/myinc.h
::::::::::::::
char* mystringh_file = __FILE__;
char* mystringh_filename = __FILE_NAME__;
char* mystringh_base_file = __BASE_FILE__;
::::::::::::::
mydir/mysrc.c
::::::::::::::

char* mystring_file = __FILE__;
char* mystring_filename = __FILE_NAME__;
char* mystring_base_file = __BASE_FILE__;

we produce:
$ gcc mydir/mysrc.c -I . -E
char* mystringh_file = "./mydir/myinc.h";
char* mystringh_filename = "myinc.h";
char* mystringh_base_file = "mydir/mysrc.c";

char* mystring_file = "mydir/mysrc.c";
char* mystring_filename = "mysrc.c";
char* mystring_base_file = "mydir/mysrc.c";

71d38ec800 preprocessor: Support C2X #elifdef, #elifndef 
C2X adds #elifdef and #elifndef preprocessor directives; these have
also been proposed for C++.  Implement these directives in libcpp
accordingly.

In this implementation, #elifdef and #elifndef are treated as
non-directives for any language version other than c2x and gnu2x (if
the feature is accepted for C++, it can trivially be enabled for
relevant C++ versions).  In strict conformance modes for prior
language versions, this is required, as illustrated by the
c11-elifdef-1.c test added.

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

	* include/cpplib.h (struct cpp_options): Add elifdef.
	* init.c (struct lang_flags): Add elifdef.

1f9db6929d c++: header-unit build capability [PR 99023] 
This defect really required building header-units and include translation
of pieces of the standard library.  This adds smarts to the modules
test harness to do that -- accept .X files as the source file, but
provide '-x c++-system-header $HDR' in the options.  The .X file will
be considered by the driver to be a linker script and ignored (with a
warning).

Using this we can add 2 tests that end up building list_initializer
and iostream, along with a test that iostream's build
include-translates list_initializer's #include.  That discovered a set
of issues with the -flang-info-include-translate=HDR handling, also
fixed and documented here.

13f93cf533 preprocessor: Add deferred macros 
Deferred macros are needed for C++ modules.  Header units may export
macro definitions and undefinitions.  These are resolved lazily at the
point of (potential) use.  (The language specifies that, it's not just
a useful optimization.)  Thus, identifier nodes grow a 'deferred'
field, which fortunately doesn't expand the structure on 64-bit
systems as there was padding there.  This is non-zero on NT_MACRO
nodes, if the macro is deferred.  When such an identifier is lexed, it
is resolved via a callback that I added recently.  That will either
provide the macro definition, or discover it there was an overriding
undef.  Either way the identifier is no longer a deferred macro.
Notice it is now possible for NT_MACRO nodes to have a NULL macro
expansion.

c9c3d5f28a preprocessor: C++ module-directives 
C++20 modules introduces a new kind of preprocessor directive -- a
module directive.  These are directives but without the leading '#'.
We have to detect them by sniffing the start of a logical line.  When
detected we replace the initial identifiers with unspellable tokens
and pass them through to the language parser the same way deferred
pragmas are.  There's a PRAGMA_EOL at the logical end of line too.

One additional complication is that we have to do header-name lexing
after the initial tokens, and that requires changes in the macro-aware
piece of the preprocessor.  The above sniffer sets a counter in the
lexer state, and that triggers at the appropriate point.  We then do
the same header-name lexing that occurs on a #include directive or
has_include pseudo-macro.  Except that the header name ends up in the
token stream.

A couple of token emitters need to deal with the new token possibility.

1d00f8c863 c: C2x __has_c_attribute 
C2x adds the __has_c_attribute preprocessor operator, similar to C++
__has_cpp_attribute.

GCC implements __has_cpp_attribute as exactly equivalent to
__has_attribute.  (The documentation says they differ regarding the
values returned for standard attributes, but that's actually only a
matter of the particular nonzero value returned not being specified in
the documentation for __has_attribute; the implementation makes no
distinction between the two.)

I don't think having them exactly equivalent is actually correct,
either for __has_cpp_attribute or for __has_c_attribute.
Specifically, I think it is only correct for __has_cpp_attribute or
__has_c_attribute to return nonzero if the given attribute is
supported, with the particular pp-tokens passed to __has_cpp_attribute
or __has_c_attribute, with [[]] syntax, not if it's only accepted in
__attribute__ or with gnu:: added in [[]].  For example, they should
return nonzero for gnu::packed, but zero for plain packed, because
[[gnu::packed]] is accepted but [[packed]] is ignored as not a
standard attribute.

This patch implements that for __has_c_attribute, leaving any changes
to __has_cpp_attribute for the C++ maintainers.  A new
BT_HAS_STD_ATTRIBUTE is added for __has_c_attribute (which I think,
based on the above, would actually be correct to use for
__has_cpp_attribute as well).  The code in c_common_has_attribute that
deals with scopes has its C++ conditional removed; instead, whether
the language is C or C++ is used only to determine the numeric values
returned for standard attributes (and which standard attributes are
handled there at all).  A new argument is passed to
c_common_has_attribute to distinguish BT_HAS_STD_ATTRIBUTE from
BT_HAS_ATTRIBUTE, and that argument is used to stop attributes with no
scope specified from being accepted with __has_c_attribute unless they
are one of the known standard attributes and so handled specially.

Although the standard specify constants ending with 'L' as the values
for the standard attributes, there is no correctness issue with the
lack of code in GCC to add that 'L' to the expansion:
__has_c_attribute and __has_cpp_attribute are expanded in #if after
other macro expansion has occurred, with no semantics being specified
if they occur outside #if, so there is no way for a conforming program
to inspect the exact text of the expansion of those macros, only to
use the resulting pp-number in a #if expression, where long and int
have the same set of values.

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

4b5f564a5d libcpp: Provide date routine 
Joseph pointed me at cb_get_source_date_epoch, which allows repeatable
builds and solves a FIXME I had on the modules branch.  Unfortunately
it's used exclusively to generate __DATE__ and __TIME__ values, which
fallback to using a time(2) call.  It'd be nicer if the preprocessor
made whatever time value it determined available to the rest of the
compiler.  So this patch adds a new cpp_get_date function, which
abstracts the call to the get_source_date_epoch hook, or uses time
directly.  The value is cached.  Thus the timestamp I end up putting
on CMI files matches __DATE__ and __TIME__ expansions.  That seems
worthwhile.

6bf2ff0d52 preprocessor: Better line info for <builtin> & <command-line> 
With C++ module header units it becomes important to distinguish
between macros defined in forced headers (& commandline & builtins)
from those defined in the header file being processed.  We weren't
making that easy because we treated the builtins and command-line
locations somewhat file-like, with incrementing line numbers, and
showing them as included from line 1 of the main file.  This patch does
3 things:

0) extend the idiom that 'line 0' of a file means 'the file as a whole'

1) builtins and command-line macros are shown as-if included from line zero.

2) when emitting preprocessed output we keep resetting the line number
so that re-reading that preprocessed output will get the same set of
locations for the command line etc.

For instance the new c-c++-common/cpp/line-2.c test, now emits

In file included from <command-line>:
./line-2.h:4:2: error: #error wrong
    4 | #error wrong
      |  ^~~~~
line-2.c:3:11: error: macro "bill" passed 1 arguments, but takes just 0
    3 | int bill(1);
      |           ^
In file included from <command-line>:
./line-2.h:3: note: macro "bill" defined here
    3 | #define bill() 2
      |

Before it told you about including from <command-line>:31.

the preprocessed output looks like:
...

(There's a new optimization in do_line_marker to stop each of these
line markers causing a new line map.  We can simply rewind the
location, and keep using the same line map.)

b224c3763e preprocessor: Reimplement directives only processing, support raw literals. 
The existing directives-only code (a) punched a hole through the
libcpp interface and (b) didn't support raw string literals.  This
reimplements this preprocessing mode.  I added a proper callback
interface, and adjusted c-ppoutput to use it.  Sadly I cannot get rid
of the libcpp/internal.h include for unrelated reasons.

The new scanner is in lex.x, and works doing some backwards scanning
when it finds a charater of interest.  This reduces the number of
cases one has to deal with in forward scanning.  It may have different
failure mode than forward scanning on bad tokenization.

3d056cbfb3 preprocessor: Make __has_include a builtin macro [PR93452] 
The clever hack of '#define __has_include __has_include' breaks -dD

ad1a3914ae [PR 80005] Fix __has_include 
__has_include is funky in that it is macro-like from the POV of #ifdef and
friends, but lexes its parenthesize argument #include-like.  We were
failing the second part of that, because we used a forwarding macro to an
internal name, and hence always lexed the argument in macro-parameter
context.  We componded that by not setting the right flag when lexing, so
it didn't even know.  Mostly users got lucky.

This reimplements the handline.
1) Remove the forwarding, but declare object-like macros that
expand to themselves.  This satisfies the #ifdef requirement

2) Correctly set angled_brackets when lexing the parameter.  This tells
the lexer (a) <...> is a header name and (b) "..." is too (not a string).

3) Remove the in__has_include lexer state, just tell find_file that that's
what's happenning, so it doesn't emit an error.

We lose the (undocumented) ability to #undef __has_include.  That may well
have been an accident of implementation.  There are no tests for it.

We gain __has_include behaviour for all users of the preprocessors -- not
just the C-family ones that defined a forwarding macro.

b7689b962d Implement C++20 operator<=>. 
There are three major pieces to this support: scalar operator<=>,
synthesis of comparison operators, and rewritten/reversed overload
resolution (e.g. a < b becomes 0 > b <=> a).

Unlike other defaulted functions, where we use synthesized_method_walk to
semi-simulate what the definition of the function will be like, this patch
determines the characteristics of a comparison operator by trying to define
it.

My handling of non-dependent rewritten operators in templates can still use
some work: build_min_non_dep_op_overload can't understand the rewrites and
crashes, so I'm avoiding it for now by clearing *overload.  This means we'll
do name lookup again at instantiation time, which can incorrectly mean a
different result.  I'll poke at this more in stage 3.

I'm leaving out a fourth section ("strong structural equality") even though
I've implemented it, because it seems likely to change radically tomorrow.

Thanks to Tim van Deurzen and Jakub for implementing lexing of the <=>
operator, and Jonathan for the initial <compare> header.

175a85b297 Support decimal floating-point constants in C2x. 
ISO C2x adds decimal floating point as an optional standard feature.
This patch accordingly makes GCC accept DFP constants (DF, DD, DL, df,
dd, dl suffixes) in strict C2X mode, with a pedwarn-if-pedantic for
older standards and a warning with -Wc11-c2x-compat even in C2x mode
(which in turn requires -Wc11-c2x-compat to be newly passed through to
libcpp).

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

93313b94fe Handle :: tokens in C for C2x. 
As part of adding [[]]-style attributes, C2x adds the token :: for use
in scoped attribute names.

This patch adds corresponding support for that token in C to GCC.  The
token is supported both for C2x and for older gnu* standards (on the
basis that extensions are normally supported in older gnu* versions;
people will expect to be able to use [[]] attributes, before C2x is
the default, without needing to use -std=gnu2x).

There are no cases in older C standards where the token : can be
followed by a token starting with : in syntactically valid sources;
the only cases the :: token could break in older standard C thus are
ones involving concatenation of pp-tokens where the result does not
end up as tokens (e.g., gets stringized).  In GNU C extensions, the
main case where :: might appear in existing sources is in asm
statements, and the C parser is thus made to handle it like two
consecutive : tokens, which the C++ parser already does.  A limited
test of various positionings of :: in asm statements is added to the
testsuite (in particular, to cover the syntax error when :: means too
many colons but a single : would be OK), but existing tests cover a
variety of styles there anyway.

Technically there are cases in Objective-C and OpenMP for which this
also changes how previously valid code is lexed: the objc-selector-arg
syntax allows multiple consecutive : tokens (although I don't think
they are particularly useful there), while OpenMP syntax includes
array section syntax such as [:] which, before :: was a token, could
also be written as [::> (there might be other OpenMP cases potentially
affected, I didn't check all the OpenMP syntax in detail).  I don't
think either of those cases affects the basis for supporting the ::
token in all -std=gnu* modes, or that there is any obvious need to
special-case handling of CPP_SCOPE tokens for those constructs the way
there is for asm statements.

cpp_avoid_paste, which determines when spaces need adding between
tokens in preprocessed output where there wouldn't otherwise be
whitespace between them (e.g. if stringized), already inserts space
between : and : unconditionally, rather than only for C++, so no
change is needed there (but a C2x test is added that such space is
indeed inserted).

Bootstrapped with no regressions on x86-64-pc-linux-gnu.

9f936c8613 Add -std=c2x, -std=gnu2x, -Wc11-c2x-compat, C2X _Static_assert support. 
Now new features are starting to be added to a C2X draft (in the C2x
branch of the C standard git repository, no public WG14 document yet),
it's time to add -std=c2x and associated options to GCC for use in
enabling C2X features.

This patch adds the expected set of options: -std=c2x, -std=gnu2x,
-Wc11-c2x-compat.  A first C2X feature is added (the only one so far
in the repository that's obviously relevant to GCC): support (as in
C++) for the string constant to be omitted in _Static_assert.  This
feature is duly also supported as an extension in earlier standard
modes (diagnosed with -pedantic, unless -Wno-c11-c2x-compat is given,
or with -Wc11-c2x-compat even in C2X mode).

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

gcc/
	* doc/cpp.texi (__STDC_VERSION__): Document C2X handling.
	* doc/invoke.texi (-std=c2x, -std=gnu2x): Document new options.
	* doc/standards.texi (C Language): Document C2X.
	* dwarf2out.c (highest_c_language), config/rl78/rl78.c
	(rl78_option_override): Handle "GNU C2X" language name.

	* c-errors.c (pedwarn_c11): New function.
	* c-parser.c (disable_extension_diagnostics): Save
	warn_c11_c2x_compat and set it to 0.
	(restore_extension_diagnostics): Restore warn_c11_c2x_compat.
	(c_parser_static_assert_declaration_no_semi): Handle
	_Static_assert without string constant.
	* c-tree.h (pedwarn_c11): New prototype.

	* c-common.c (flag_isoc2x): New variable.
	* c-common.h (clk_c): Update comment to reference C2X.
