Support for 64-bit location_t: libcpp preliminaries 
Prepare libcpp to support 64-bit location_t, without yet making
any functional changes, by adding new typedefs that enable code to be
written such that it works with any size location_t. Update the usage of
line maps within libcpp accordingly.

Subsequent patches will prepare the rest of the codebase similarly, and then
afterwards, location_t will be changed to uint64_t.

libcpp/ChangeLog:

	* include/line-map.h (line_map_uint_t): New typedef, the same type
	as location_t.
	(location_diff_t): New typedef.
	(line_map_suggested_range_bits): New constant.
	(struct maps_info_ordinary): Change member types from "unsigned int"
	to "line_map_uint_t".
	(struct maps_info_macro): Likewise.

	becomes a 64-bit type.
	* line-map.cc (location_adhoc_data_hash): Don't truncate to 32-bit
	prematurely when hashing.
	(line_maps::get_or_create_combined_loc): Adapt types to support
	potentially 64-bit location_t. Use MAX_LOCATION_T rather than a
	hard-coded constant.

1ae24f7e0b c++: Attempt to implement C++26 P3034R1 - Module Declarations Shouldn't be Macros [PR114461] 
This is an attempt to implement the https://wg21.link/p3034r1 paper,
but I'm afraid the wording in the paper is bad for multiple reasons.
I think I understand the intent, that the module name and partition
if any shouldn't come from macros so that they can be scanned for
without preprocessing, but on the other side doesn't want to disable
macro expansion in pp-module altogether, because e.g. the optional
attribute in module-declaration would be nice to come from macros
as which exact attribute is needed might need to be decided based on
preprocessor checks.
The paper added https://eel.is/c++draft/cpp.module#2
which uses partly the wording from https://eel.is/c++draft/cpp.module#1

The first issue I see is that using that "defined as an object-like macro"
from there means IMHO something very different in those 2 paragraphs.
As per https://eel.is/c++draft/cpp.pre#7.sentence-1 preprocessing tokens
in preprocessing directives aren't subject to macro expansion unless
otherwise stated, and so the export and module tokens aren't expanded
and so the requirement that they aren't defined as an object-like macro
makes perfect sense.  The problem with the new paragraph is that
https://eel.is/c++draft/cpp.module#3.sentence-1 says that the rest of
the tokens are macro expanded and after macro expansion none of the
tokens can be defined as an object-like macro, if they would be, they'd
be expanded to that.  So, I think either the wording needs to change
such that not all preprocessing tokens after module are macro expanded,
only those which are after the pp-module-name and if any pp-module-partition
tokens, or all tokens after module are macro expanded but none of the tokens in
pp-module-name and pp-module-partition if any must come from macro
expansion.  The patch below implements it as if the former would be
specified (but see later), so essentially scans the preprocessing tokens
after module without expansion, if the first one is an identifier, it
disables expansion for it and then if followed by . or : expects another
such identifier (again with disabled expansion), but stops after second
: is seen.

Second issue is that while the global-module-fragment start is fine, matches
the syntax of the new paragraph where the pp-tokens[opt] aren't present,
there is also private-module-fragment in the syntax where module is
followed by : private ; and in that case the colon doesn't match the
pp-module-name grammar and appears now to be invalid.  I think the
https://eel.is/c++draft/cpp.module#2
paragraph needs to change so that it allows also that pp-tokens of
a pp-module may also be : pp-tokens[opt] (and in that case, I think
the colon shouldn't come from a macro and private and/or ; can).

Third issue is that there are too many pp-tokens in
https://eel.is/c++draft/cpp.module , one is all the tokens between
module keyword and the semicolon and one is the optional extra tokens
after pp-module-partition (if any, if missing, after pp-module).
Perhaps introducing some other non-terminal would help talking about it?
So in "where the pp-tokens (if any) shall not begin with a ( preprocessing
token" it isn't obvious which pp-tokens it is talking about (my assumption
is the latter) and also whether ( can't appear there just before macro
expansion or also after expansion.  The patch expects only before expansion,
so
 #define F ();
 export module foo F
would be valid during preprocessing but obviously invalid during
compilation, but
 #define foo(n) n;
 export module foo (3)
would be invalid already during preprocessing.

The last issue applies only if the first issue is resolved to allow
expansion of tokens after : if first token, or after pp-module-partition
if present or after pp-module-name if present.  When non-preprocessing
scanner sees
 export module foo.bar:baz.qux;
it knows nothing can come from preprocessing macros and is ok, but if it
sees
 export module foo.bar:baz qux
then it can't know whether it will be
 export module foo.bar:baz;
or
 export module foo.bar:baz [[]];
or
 export module foo.bar:baz.freddy.garply;
because qux could be validly a macro, which expands to ; or [[]];
or .freddy.garply; etc.  So, either the non-preprocessing scanner would
need to note it as possible export of foo.bar:baz* module partitions
and preprocess if it needs to know the details or just compile, or if that
is not ok, the wording would need to rule out that the expansion of (the
second) pp-tokens if any can't start with . or : (colon would be only
problematic if it isn't present in the tokens before it already).
So, if e.g. defining qux above to . whatever is invalid, then the scanner
can rely it sees the whole module name and partition.

The patch below implements what is above described as the first variant
of the first issue resolution, i.e. disables expansion of as many tokens
as could be in the valid module name and module partition syntax, but
as soon as it e.g. sees two adjacent identifiers, the second one can be
macro expanded.  If it is macro expanded though, the expansion can't
start with . or :, and if it expands to nothing, tokens after it (whether
they come from macro expansion or not) can't start with . or :.
So, effectively:
 #define SEMI ;
 export module SEMI
used to be valid and isn't anymore,
 #define FOO bar
 export module FOO;
isn't valid,
 #define COLON :
 export module COLON private;
isn't valid,
 #define BAR baz
 export module foo.bar:baz.qux.BAR;
isn't valid,
 #define BAZ .qux
 export module foo BAZ;
isn't valid,
 #define FREDDY :garply
 export module foo FREDDY;
isn't valid,
while
 #define QUX [[]]
 export module foo QUX;
or
 #define GARPLY private
 module : GARPLY;
etc. is.

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).

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.

ce0aecc7df libcpp, v2: Add support for gnu::base64 #embed parameter 
This patch which adds another #embed extension, gnu::base64.

As mentioned in the documentation, this extension is primarily
intended for use by the preprocessor, so that for the larger (say 32+ or
64+ bytes long embeds it doesn't have to emit tens of thousands or
millions of comma separated string literals which would be very expensive
to parse again, but can emit
 #embed "." __gnu__::__base64__( \

with the meaning don't actually load some file, instead base64 decode
(RFC4648 with A-Za-z0-9+/ chars and = padding, no newlines in between)
the string and use that as data.  This is chosen because it should be
-pedantic-errors clean, fairly cheap to decode and then in optimizing
compiler could be handled as similar binary blob to normal #embed,
while the data isn't left somewhere on the disk, so distcc/ccache etc.
can move the preprocessed source without issues.
It makes no sense to support limit and gnu::offset parameters together
with it IMHO, why would somebody waste providing full data and then
threw some away?  prefix/suffix/if_empty are normally supported though,
but not intended to be used by the preprocessor.

This patch adds just the extension side, not the actual emitting of this
during -E or -E -fdirectives-only for now, that will be included in the
upcoming patch.

Compared to the earlier posted version of this extension, this patch
allows the string concatenation in the parameter argument (but still
doesn't allow escapes in the string, why would anyone use them when
only A-Za-z0-9+/= are valid).  The patch also adds support for parsing
this even in -fpreprocessed compilation.

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.

eba6d2aa71 libcpp, c-family: Add (dumb) C23 N3017 #embed support [PR105863] 
The following patch implements the C23 N3017 "#embed - a scannable,
tooling-friendly binary resource inclusion mechanism" paper.

The implementation is intentionally dumb, in that it doesn't significantly
speed up compilation of larger initializers and doesn't make it possible
to use huge #embeds (like several gigabytes large, that is compile time
and memory still infeasible).
There are 2 reasons for this.  One is that I think like it is implemented
now in the patch is how we should use it for the smaller #embed sizes,
dunno with which boundary, whether 32 bytes or 64 or something like that,
certainly handling the single byte cases which is something that can appear
anywhere in the source where constant integer literal can appear is
desirable and I think for a few bytes it isn't worth it to come up with
something smarter and users would like to e.g. see it in -E readably as
well (perhaps the slow vs. fast boundary should be determined by command
line option).  And the other one is to be able to more easily find
regressions in behavior caused by the optimizations, so we have something
to get back in git to compare against.
I'm definitely willing to work on the optimizations (likely introduce a new
CPP_* token type to refer to a range of libcpp owned memory (start + size)
and similarly some tree which can do the same, and can be at any time e.g.
split into 2 subparts + say INTEGER_CST in between if needed say for
const unsigned char d[] = {
 #embed "2GB.dat" prefix (0, 0, ) suffix (, [0x40000000] = 42)
}; still without having to copy around huge amounts of data; STRING_CST
owns the memory it points to and can be only 2GB in size), but would
like to do that incrementally.
And would like to first include some extensions also not included in
this patch, like gnu::offset (off) parameter to allow to skip certain
constant amount of bytes at the start of the files, plus
gnu::base64 ("base64_encoded_data") parameter to add something which can
store more efficiently large amounts of the #embed data in preprocessed
source.

I've been cross-checking all the tests also against the LLVM implementation
https://github.com/llvm/llvm-project/pull/68620
which has been for a few hours even committed to LLVM trunk but reverted
afterwards.  LLVM now has the support committed and I admit I haven't
rechecked whether the behavior on the below mentioned spots have been fixed
in it already or not yet.

The patch uses --embed-dir= option that clang plans to add above and doesn't
use other variants on the search directories yet, plus there are no
default directories at least for the time being where to search for embed
files.  So, #embed "..." works if it is found in the same directory (or
relative to the current file's directory) and #embed "/..." or #embed </...>
work always, but relative #embed <...> doesn't unless at least one
--embed-dir= is specified.  There is no reason to differentiate between
system and non-system directories, so we don't need -isystem like
counterpart, perhaps -iquote like counterpart could be useful in the future,
dunno what else.  It has --embed-directory=dir and --embed-directory dir
as aliases.

There are some differences beyond clang ICEs, so I'd like to point them out
to make sure there is agreement on the choices in the patch.  They are also
mentioned in the comments of the llvm pull request.

The most important is that the GCC patch (as well as the original thephd.dev
LLVM branch on godbolt) expands #embed (or acts as if it is expanded) into
a mere sequence of numbers like 123,2,35,26 rather then what clang
effectively treats as (unsigned char)123,(unsigned char)2,(unsigned
char)35,(unsigned char)26 but only does that when using integrated
preprocessor, not when using -save-temps where it acts as GCC.
JeanHeyd as the original author agrees that is how it is currently worded in
C23.

Another difference (not tested in the testsuite, not sure how to check for
effective target /dev/urandom nor am sure it is desirable to check that
during testsuite) is how to treat character devices, named pipes etc.
(block devices are errored on).  The original paper uses /dev/urandom
in various examples and seems to assume that unlike regular files the
devices aren't really cached, so
 #embed </dev/urandom> limit(1) prefix(int a = ) suffix(;)
 #embed </dev/urandom> limit(1) prefix(int b = ) suffix(;)
usually results in a != b.  That is what the godbolt thephd.dev branch
implements too and what this patch does as well, but clang actually seems
to just go from st.st_size == 0, ergo it must be zero-sized resource and
so just copies over if_empty if present.  It is really questionable
what to do about the character devices/named pipes with __has_embed, for
regular files the patch doesn't read anything from them, relies on
st.st_size + limit for whether it is empty or non-empty.  But I don't know
of a way to check if read on say a character device would read anything
or not (the </dev/null> limit (1) vs. </dev/zero> limit (1) cases), and
if we read something, that would be better cached for later because
 #embed later if it reads again could read no further data even when it
first read something.  So, the patch currently for __has_embed just
always returns 2 on the non-regular files, like the thephd.dev
branch does as well and like the clang pull request as well.
A question is also what to do for gnu::offset on the non-regular files
even for #embed, those aren't seekable and do we want to just read and throw
away the offset bytes each time we see it used?

clang also chokes on the
 #if __has_embed (__FILE__ __limit__ (1) __prefix__ () suffix (1 / 0) \
 __if_empty__ ((({{[0[0{0{0(0(0)1)1}1}]]}})))) != __STDC_EMBED_FOUND__
 #error "__has_embed fail"
 #endif
in embed-1.c, but thephd.dev branch accepts it and I don't see why
it shouldn't, (({{[0[0{0{0(0(0)1)1}1}]]}}))) is a balanced token
sequence and the file isn't empty, so it should just be parsed and
discarded.

clang also IMHO mishandles
 const unsigned char w[] = {
 #embed __FILE__ prefix([0] = 42, [15] =) limit(32)
 };
but again only without -save-temps, seems like it
treats it as
[0] = 42, [15] = (99,111,110,115,116,32,117,110,115,105,103,110,101,100,
32,99,104,97,114,32,119,91,93,32,61,32,123,10,35,101,109,98)
rather than
[0] = 42, [15] = 99,111,110,115,116,32,117,110,115,105,103,110,101,100,
32,99,104,97,114,32,119,91,93,32,61,32,123,10,35,101,109,98
and warns on it for -Wunused-value and just compiles it as
[0] = 42, [15] = 98

And also
 void foo (int, int, int, int);
 void bar (void) { foo (
 #embed __FILE__ limit (4) prefix (172 + ) suffix (+ 2)
 ); }
is treated as
172 + (118, 111, 105, 100) + 2
rather than
172 + 118, 111, 105, 100 + 2
which clang -save-temps or GCC treats it like, so results
in just one argument passed rather than 4.

if (!strstr ((const char *) magna_carta, "imprisonétur")) abort ();
in the testcase fails as well, but in that case calling it in gdb succeeds:
p ((char *(*)(char *, char *))__strstr_sse2) (magna_carta, "imprisonétur")
$2 = 0x555555558d3c <magna_carta+11564> "imprisonétur aut disseisiátur"...
so I guess they are just trying to constant evaluate strstr and do it
incorrectly.

They started with making the optimizations together in the initial patch
set, so they don't have the luxury to compare if it is just because of
the optimization they are trying to do or because that is how the
feature works for them.  At least unless they use -save-temps for now.

There is also different behavior between clang and gcc on -M or other
dependency generating options.  Seems clang includes the __has_embed
searched files in dependencies, while my patch doesn't.  But so does
clang for __has_include and GCC doesn't.  Emitting a hard dependency
on some header just because there was __has_include/__has_embed for it
seems wrong to me, because (at least when properly written) the source
likely doesn't mind if the file is missing, it will do something else,
so a hard error from make because of it doesn't seem right.  Does
make have some weaker dependencies, such that if some file can be remade
it is but if it doesn't exist, it isn't fatal?

I wonder whether #embed <non-existent-file> really needs to be fatal
or whether we could simply after diagnosing it pretend the file exists
and is empty.  For #include I think fatal errors make tons of sense,
but perhaps for #embed which is more localized we'd get better error
reporting if we didn't bail out immediately.  Note, both GCC and clang
currently treat those as fatal errors.

clang also added -dE option which with -E instead of preprocessing
the #embed directives keeps them as is, but the preprocessed source
then isn't self-contained.  That option looks more harmful than useful to
me.

Also, it isn't clear to me from C23 whether it is possible to have
__has_include/__has_c_attribute/__has_embed expressions inside of
the limit #embed/__has_embed argument.
6.10.3.2/2 says that defined should not appear there (and the patch
diagnoses it and testsuite tests), but for __has_include/__has_embed
etc. 6.10.1/11 says:
"The identifiers __has_include, __has_embed, and __has_c_attribute
shall not appear in any context not mentioned in this subclause."
If that subclause in that case means 6.10.1, then it presumably shouldn't
appear in #embed in 6.10.3, but __has_embed is in 6.10.1...
But 6.10.3.2/3 says that it should be parsed according to the 6.10.1
rules.  Haven't included tests like
 #if __has_embed (__FILE__ limit (__has_embed (__FILE__ limit (1))))
or
 #embed __FILE__ limit (__has_include (__FILE__))
into the testsuite because of the doubts but I think the patch should
handle those right now.

The reason I've used Magna Carta text in some of the testcases is that
I hope it shouldn't be copyrighted after the centuries and I'd strongly
prefer not to have binary blobs in git after the xz backdoor lesson
and wanted something larger which doesn't change all the time.

Oh, BTW, I see in C23 draft 6.10.3.2 in Example 4
if (f_source == NULL);
  return 1;
(note the spurious semicolon after closing paren), has that been fixed
already?

Like the thephd.dev and clang implementations, the patch always macro
expands the whole #embed and __has_embed directives except for the
embed keyword.  That is most likely not what C23 says, my limited
understanding right now is that in #embed one needs to parse the whole
directive line with macro expansion disabled and check if it satisfies the
grammar, if not, the whole directive is macro expanded, if yes, only
the limit parameter argument is macro expanded and the prefix/suffix/if_empty
arguments are maybe macro expanded when actually used (and not at all if
unused).  And I think __has_embed macro expansion has conflicting rules.

942497ad74 libcpp: Fix macro expansion for argument of __has_include [PR110558] 
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.

4f3be7cbeb libcpp: Improve location for macro names [PR66290] 
When libcpp reports diagnostics whose locus is a macro name (such as for
-Wunused-macros), it uses the location in the cpp_macro object that was
stored by _cpp_new_macro. This is currently set to pfile->directive_line,
which contains the line number only and no column information. This patch
changes the stored location to the src_loc for the token defining the macro
name, which includes the location and range information.

libcpp/ChangeLog:

	PR c++/66290
	* macro.cc (_cpp_create_definition): Add location argument.
	* internal.h (_cpp_create_definition): Adjust prototype.
	* directives.cc (do_define): Pass new location argument to
	_cpp_create_definition.
	(do_undef): Stop passing inferior location to cpp_warning_with_line;
	the default from cpp_warning is better.

ce53cf7b61 preprocessor: Enable __VA_OPT__ for C2x 
C2x supports __VA_OPT__, so adjust libcpp not to pedwarn for uses of
it (or of not passing any variable arguments to a variable-arguments
macro) in standard C2x mode.

I didn't try to duplicate existing tests for the details of the
feature, just verified -pedantic-errors handling is as expected.  And
there's a reasonable argument (bug 98859) that __VA_OPT__ shouldn't be
diagnosed in older standard modes at all (as opposed to not passing
any variable arguments to a variable-arguments macro, for which older
versions of the C standard require a diagnostic as a constraint
violation); that argument applies to C as much as to C++, but I
haven't made any changes in that regard.

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

libcpp/
	* init.cc (lang_defaults): Enable va_opt for STDC2X.

11543b27fe libcpp: Avoid remapping filenames within directives 
Code such as:

 #include __FILE__

can interact poorly with the *-prefix-map options when cross compiling. In
general you're after to remap filenames for use in target context but the
local paths should be used to find include files at compile time. Ingoring
filename remapping for directives allows avoiding such failures.

Fix this to improve such usage and then document this against file-prefix-map
(referenced by the other *-prefix-map options) to make the behaviour clear
and defined.

libcpp/ChangeLog:

	* macro.cc (_cpp_builtin_macro_text): Don't remap filenames within
	directives.

gcc/ChangeLog:

	* doc/invoke.texi: Document prefix-maps don't affect directives.

95ac563540 libcpp: Fix up padding handling in funlike_invocation_p [PR104147] 
As mentioned in the PR, in some cases we preprocess incorrectly when we
encounter an identifier which is defined as function-like macro, followed
by at least 2 CPP_PADDING tokens and then some other identifier.
On the following testcase, the problem is in the 3rd funlike_invocation_p,
the tokens are CPP_NAME Y, CPP_PADDING (the pfile->avoid_paste shared token),
CPP_PADDING (one created with padding_token, val.source is non-NULL and
val.source->flags & PREV_WHITE is non-zero) and then another CPP_NAME.
funlike_invocation_p remembers there was a padding token, but remembers the
first one because of its condition, then the next token is the CPP_NAME,
which is not CPP_OPEN_PAREN, so the CPP_NAME token is backed up, but as we
can't easily backup more tokens, it pushes into a new context the padding
token (the pfile->avoid_paste one).  The net effect is that when Y is not
defined as fun-like macro, we read Y, avoid_paste, padding_token, Y,
while if Y is fun-like macro, we read Y, avoid_paste, avoid_paste, Y
(the second avoid_paste is because that is how we handle end of a context).
Now, for stringify_arg that is unfortunately a significant difference,
which handles CPP_PADDING tokens with:
      if (token->type == CPP_PADDING)
        {
          if (source == NULL
              || (!(source->flags & PREV_WHITE)
                  && token->val.source == NULL))
            source = token->val.source;
          continue;
        }
and later on
      /* Leading white space?  */
      if (dest - 1 != BUFF_FRONT (pfile->u_buff))
        {
          if (source == NULL)
            source = token;
          if (source->flags & PREV_WHITE)
            *dest++ = ' ';
        }
      source = NULL;
(and c-ppoutput.cc has similar code).
So, when Y is not fun-like macro, ' ' is added because padding_token's
val.source->flags & PREV_WHITE is non-zero, while when it is fun-like
macro, we don't add ' ' in between, because source is NULL and so
used from the next token (CPP_NAME Y), which doesn't have PREV_WHITE set.

Now, the funlike_invocation_p condition
       if (padding == NULL
           || (!(padding->flags & PREV_WHITE) && token->val.source == NULL))
        padding = token;
looks very similar to that in stringify_arg/c-ppoutput.cc, so I assume
the intent was to prefer do the same thing and pick the right padding.
But there are significant differences.  Both stringify_arg and c-ppoutput.cc
don't remember the CPP_PADDING token, but its val.source instead, while
in funlike_invocation_p we want to remember the padding token that has the
significant information for stringify_arg/c-ppoutput.cc.
So, IMHO we want to overwrite padding if:
1) padding == NULL (remember that there was any padding at all)
2) padding->val.source == NULL (this matches the source == NULL
   case in stringify_arg)
3) !(padding->val.source->flags & PREV_WHITE) && token->val.source == NULL
   (this matches the !(source->flags & PREV_WHITE) && token->val.source == NULL
   case in stringify_arg)
