d538348556 libcpp: Improve locations for macros defined prior to PCH include [PR105608] 
It is permissible to define macros prior to including a PCH, as long as
these definitions are disjoint from or identical to the macros in the
PCH. The PCH loading process replaces all libcpp data structures with those
from the PCH, so it is necessary to remember the extra macros separately and
then restore them after loading the PCH, which all is handled by
cpp_save_state() and cpp_read_state() in libcpp/pch.cc. The restoration
process consists of pushing a buffer containing the macro definition and
then lexing it from there, similar to how a command-line -D option is
processed. The current implementation does not attempt to set up the
line_map for this process, and so the locations assigned to the macros are
often not meaningful. (Similar to what happened in the past with lexing the
tokens out of a _Pragma string, lexing out of a buffer rather than a file
produces "sorta" reasonable locations that are often close enough, but not
reliably correct.)

Fix that up by remembering enough additional information (more or less, an
expanded_location for each macro definition) to produce a reasonable
location for the newly restored macros.

One issue that came up is the treatment of command-line-defined macros. From
the perspective of the generic line_map data structures, the command-line
location is not distinguishable from other locations; it's just an ordinary
location created by the front ends with a fake file name by convention. (At
the moment, it is always the string `<command-line>', subject to
translation.)  Since libcpp needs to assign macros to that location, it
needs to know what location to use, so I added a new member
line_maps::cmdline_location for the front ends to set, similar to how
line_maps::builtin_location is handled.

This revealed a small issue, in c-opts.cc we have:

    /* All command line defines must have the same location.  */
      cpp_force_token_locations (parse_in, line_table->highest_line);

But contrary to the comment, all command line defines don't actually end up
with the same location anymore. This is because libcpp/lex.cc has been
expanded (r6-4873) to include range information on the returned
locations. That logic has never been respecting the request of
cpp_force_token_locations. I believe this was not intentional, and so I have
corrected that here. Prior to this patch, the range logic has been leading
to command-line macros all having similar locations in the same line map (or
ad-hoc locations based from there for sufficiently long tokens); with this
change, they all have exactly the same location and that location is
recorded in line_maps::cmdline_location.

With that change, then it works fine for pch.cc to restore macros whether
they came from the command-line or from the main file.

	* c-opts.cc (c_finish_options): Set new member
	line_table->cmdline_location.

a5933118f3 c++: modules and #pragma diagnostic 
To respect the #pragma diagnostic lines in libstdc++ headers when compiling
with module std, we need to represent them in the module.

I think it's reasonable to give serializers direct access to the underlying
data, as here with get_classification_history.  This is a different approach
from how Jakub made PCH streaming members of diagnostic_option_classifier,
but it seems to me that modules handling belongs in module.cc.

libcpp/ChangeLog:

	* line-map.cc (linemap_location_from_module_p): Add.
	* include/line-map.h: Declare it.

cb1d203445 diagnostics: make experimental-html sink prettier [PR116792] 
This patch to the "experimental-html" diagnostic sink:
* adds use of the PatternFly 3 CSS library (via an optional link
  in the generated html to a copy in a CDN)
* uses PatternFly's "alert" pattern to show severities for diagnostics,
  properly nesting "note" diagnostics for diagnostic groups.
  Example:
    before: https://dmalcolm.fedorapeople.org/gcc/2025-06-10/before/diagnostic-ranges.c.html
     after: https://dmalcolm.fedorapeople.org/gcc/2025-06-10/after/diagnostic-ranges.c.html

* adds initial support for logical locations and physical locations
* adds initial support for multi-level nested diagnostics such as those
  for C++ concepts diagnostics.  Ideally this would show a clickable
  disclosure widget to expand/collapse a level, but for now it uses
  nested <ul> elements with <li> for the child diagnostics.
  Example:
    before: https://dmalcolm.fedorapeople.org/gcc/2025-06-10/before/nested-diagnostics-1.C.html
     after: https://dmalcolm.fedorapeople.org/gcc/2025-06-10/after/nested-diagnostics-1.C.html

d9cdc500c1 Support for 64-bit location_t: Activate 64-bit location_t 
Change location_t to be a 64-bit integer instead of a 32-bit integer in
libcpp.

Also included in this change are the two other patches in the original
series which depended on this one; I am committing them all at once in case
it needs to be reverted later:

-Support for 64-bit location_t: gimple parts

The size of struct gimple increased by 8 bytes with the change in size of
location_t from 32- to 64-bit; adjust the WORD markings in the comments
accordingly. It seems that most of the WORD markings were off by one already,
probably not having been updated after a previous reduction in the size of a
gimple, so they have become retroactively correct again, and only a couple
needed adjustment actually.

Also add a comment that there is now 32 bits of unused padding available in
struct gimple for 64-bit hosts.

-Support for 64-bit location_t: Remove -flarge-source-files

The option -flarge-source-files became unnecessary with 64-bit location_t
and harms performance compared to the new default setting, so silently
ignore it.

libcpp/ChangeLog:

	* include/cpplib.h (struct cpp_token): Adjust comment about the
	struct size.
	* include/line-map.h (location_t): Change typedef from 32-bit to 64-bit
	integer.
	(LINE_MAP_MAX_COLUMN_NUMBER): Increase size to be appropriate for
	64-bit location_t.
	(LINE_MAP_MAX_LOCATION_WITH_PACKED_RANGES): Likewise.
	(LINE_MAP_MAX_LOCATION_WITH_COLS): Likewise.
	(LINE_MAP_MAX_LOCATION): Likewise.

	(line_map_suggested_range_bits): Likewise.
	(struct line_map): Adjust comment about the struct size.
	(struct line_map_macro): Likewise.
	(struct line_map_ordinary): Likewise. Rearrange fields to optimize
	padding.

gcc/testsuite/ChangeLog:

	* g++.dg/diagnostic/pr77949.C: Adapt the test for 64-bit location_t,
	when the previously expected failure doesn't actually happen.
	* g++.dg/modules/loc-prune-4.C: Adjust the expected output for the
	64-bit location_t case.
	* gcc.dg/plugin/expensive_selftests_plugin.cc: Don't try to test
	the maximum supported column number in 64-bit location_t mode.
	* gcc.dg/plugin/location_overflow_plugin.cc: Adjust the base_location
	so it can effectively test 64-bit location_t.

gcc/ChangeLog:

	* gimple.h (struct gphi): Update word marking comments to reflect
	the new size of location_t.
	(struct gimple): Likewise. Add a comment about padding.
	* common.opt: Mark -flarge-source-files as Ignored.
	* common.opt.urls: Regenerate.
	* doc/invoke.texi: Remove -flarge-source-files.

927625d007 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.

	as location_t.
	(location_diff_t): New typedef.

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).

f1adf45b17 Add instruction level discriminator support. 
This is the first in a series of patches to enable discriminator support
in AutoFDO.

This patch switches to tracking discriminators per statement/instruction
instead of per basic block. Tracking per basic block was problematic since
not all statements in a basic block needed a discriminator and, also, later
optimizations could move statements between basic blocks making correlation
during AutoFDO compilation unreliable. Tracking per statement also allows
us to assign different discriminators to multiple function calls in the same
basic block. A subsequent patch will add that support.

The idea of this patch is based on commit 4c311d95cf
by Dehao Chen in vendors/google/heads/gcc-4_8 but uses a slightly different
approach. In Dehao's work special (normally unused) location ids and side tables
were used to keep track of locations with discriminators. Things have changed
since then and I don't think we have unused location ids anymore. Instead,
I made discriminators a part of ad-hoc locations.

The difference from Dehao's work also includes support for discriminator
reading/writing in lto streaming and in modules.

Tested on x86_64-pc-linux-gnu.

This adjusts the API of label_text so that the data members are private

86a15b266a libcpp: Avoid pessimizing std::move [PR106272] 
std::move in a return statement can prevent the NRVO:
<https://developers.redhat.com/blog/2019/04/12/understanding-when-not-to-stdmove-in-c>

PR106272 reports that we have two such cases in class label_text's
member functions.  We have -Wpessimizing-move that's supposed to detect
problematic std::move uses, but in this case it didn't trigger.  I've filed
PR106276 to track that.

	PR preprocessor/106272

	* include/line-map.h (class label_text): Don't std::move in a return
	statement.

a8dce13c07 Convert label_text to C++11 move semantics 
libcpp's class label_text stores a char * for a string and a flag saying
whether it owns the buffer.  I added this class before we could use
C++11, and so to avoid lots of copying it required an explicit call
to label_text::maybe_free to potentially free the buffer.

Now that we can use C++11, this patch removes label_text::maybe_free in
favor of doing the cleanup in the destructor, and using C++ move
semantics to avoid any copying.  This allows lots of messy cleanup code
to be eliminated in favor of implicit destruction (mostly in the
analyzer).

No functional change intended.

fe7c3ecff1 pch: Add support for PCH for relocatable executables [PR71934] 
So, if we want to make PCH work for PIEs, I'd say we can:
1) add a new GTY option, say callback, which would act like
   skip for non-PCH and for PCH would make us skip it but
   remember for address bias translation
2) drop the skip for tree_translation_unit_decl::language
3) change get_unnamed_section to have const char * as
   last argument instead of const void *, change
   unnamed_section::data also to const char * and update
   everything related to that
4) maybe add a host hook whether it is ok to support binaries
   changing addresses (the only thing I'm worried is if
   some host that uses function descriptors allocates them
   dynamically instead of having them somewhere in the
   executable)
5) maybe add a gengtype warning if it sees in GTY tracked
   structure a function pointer without that new callback
   option

Here is 1), 2), 3) implemented.

Note, on stdc++.h.gch/O2g.gch there are just those 10 relocations without
the second patch, with it a few more, but nothing huge.  And for non-PIEs
there isn't really any extra work on the load side except freading two scalar
values and fseek.

bd5e882cf6 diagnostics: escape non-ASCII source bytes for certain diagnostics 
This patch adds support to GCC's diagnostic subsystem for escaping certain
bytes and Unicode characters when quoting source code.

Specifically, this patch adds a new flag rich_location::m_escape_on_output
which is a hint from a diagnostic that non-ASCII bytes in the pertinent
lines of the user's source code should be escaped when printed.

The patch sets this for the following diagnostics:
- when complaining about stray bytes in the program (when these
are non-printable)
- when complaining about "null character(s) ignored");
- for -Wnormalized= (and generate source ranges for such warnings)

The escaping is controlled by a new option:
  -fdiagnostics-escape-format=[unicode|bytes]

For example, consider a diagnostic involing a source line containing the
string "before" followed by the Unicode character U+03C0 ("GREEK SMALL
LETTER PI", with UTF-8 encoding 0xCF 0x80) followed by the byte 0xBF
(a stray UTF-8 trailing byte), followed by the string "after", where the
diagnostic highlights the U+03C0 character.

By default, this line will be printed verbatim to the user when
reporting a diagnostic at it, as:

 beforeπXafter
       ^

(using X for the stray byte to avoid putting invalid UTF-8 in this
commit message)

If the diagnostic sets the "escape" flag, it will be printed as:

 before<U+03C0><BF>after
       ^~~~~~~~

with -fdiagnostics-escape-format=unicode (the default), or as:

  before<CF><80><BF>after
        ^~~~~~~~

if the user supplies -fdiagnostics-escape-format=bytes.

This only affects how the source is printed; it does not affect
how column numbers that are printed (as per -fdiagnostics-column-unit=
and -fdiagnostics-column-origin=).

1174314811 Fix thinko in libcpp preparation patch for modules 
The problem is that the new IS_MACRO_LOC macro:

inline bool
IS_MACRO_LOC (location_t loc)
{
  return !IS_ORDINARY_LOC (loc) && !IS_ADHOC_LOC (loc);
}

is not fully correct since the position of the macro lines is not fixed:

/* Returns the lowest location [of a token resulting from macro
   expansion] encoded in this line table.  */
inline location_t
LINEMAPS_MACRO_LOWEST_LOCATION (const line_maps *set)
{
  return LINEMAPS_MACRO_USED (set)
         ? MAP_START_LOCATION (LINEMAPS_LAST_MACRO_MAP (set))
         : MAX_LOCATION_T + 1;
}

In Ada, LINEMAPS_MACRO_USED is false so LINEMAPS_MACRO_LOWEST_LOCATION is
MAX_LOCATION_T + 1, but IS_MACRO_LOC nevertheless returns true for anything
in the range [LINE_MAP_MAX_LOCATION; MAX_LOCATION_T], thus yielding an ICE
in linemap_macro_map_lookup for very large files.

f207eed69e c++: Macro location fixes [PR 98718] 
This fixes some issues with macro maps.  We were incorrectly
calculating the number of macro expansions in a location span, and I
had a workaround that partially covered that up.  Further, while macro
location spans are monotonic, that is not true of ordinary location
spans.  Thus we need to insert an indirection array when binary
searching the latter. (We load ordinary locations before loading
imports, but macro locations afterwards.  We make sure an import
location is de-macrofied, if needed.)

1f8ac75991 preprocessor: module line maps 
This patch adds LC_MODULE as a map kind, used to indicate a c++
module.  Unlike a regular source file, it only contains a single
location, and the source locations in that module are represented by
ordinary locations whose 'included_from' location is the module.

It also exposes some entry points that modules will use to create
blocks of line maps.

In the original posting, I'd missed the deletion of the
linemap_enter_macro from internal.h.  That's included here.

4839de55e2 c-family: Macro support in -Wmisleading-indentation [PR80076] 
Currently the -Wmisleading-indentation warning doesn't do any analysis
when the guarded statement or the statement after it is produced by a
macro.  This means we warn for:

  if (flag)
    foo ();
    bar ();

but not for:

  #define BAR bar
  if (flag)
    foo ();
    BAR ();

This patch extends the -Wmisleading-indentation implementation to
support analyzing such statements and their tokens.  This is done in the
"natural" way by resolving the location of each of the three tokens to
the token's macro expansion point.  (Additionally, if the tokens all
resolve to the same macro expansion point then we instead use their
locations within the macro definition.)  When these resolved locations
are all different, then we can proceed with applying the warning
heuristics to them as if no macros were involved.

	PR c/80076
	* c-indentation.c (should_warn_for_misleading_indentation): Move
	declarations of local variables closer to their first use.

4bc1899b2e Add diagnostic paths 
This patch adds support for associating a "diagnostic_path" with a
diagnostic: a sequence of events predicted by the compiler that leads to
the problem occurring, with their locations in the user's source,
text descriptions, and stack information (for handling interprocedural
paths).

For example, the following (hypothetical) error has a 3-event
intraprocedural path:

test.c: In function 'demo':
test.c:29:5: error: passing NULL as argument 1 to 'PyList_Append' which
  requires a non-NULL parameter
   29 |     PyList_Append(list, item);
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~
  'demo': events 1-3
     |
     |   25 |   list = PyList_New(0);
     |      |          ^~~~~~~~~~~~~
     |      |          |
     |      |          (1) when 'PyList_New' fails, returning NULL
     |   26 |
     |   27 |   for (i = 0; i < count; i++) {
     |      |   ~~~
     |      |   |
     |      |   (2) when 'i < count'
     |   28 |     item = PyLong_FromLong(random());
     |   29 |     PyList_Append(list, item);
     |      |     ~~~~~~~~~~~~~~~~~~~~~~~~~
     |      |     |
     |      |     (3) when calling 'PyList_Append', passing NULL from (1) as argument 1
     |

The patch adds a new "%@" format code for printing event IDs, so that
in the above, the description of event (3) mentions event (1), showing
the user where the bogus NULL value comes from (the event IDs are
colorized to draw the user's attention to them).

There is a separation between data vs presentation: the above shows how
the diagnostic-printing code has consolidated the path into a single run
of events, since all the events are near each other and within the same
function; more complicated examples (such as interprocedural paths)
might be printed as multiple runs of events.

Examples of how interprocedural paths are printed can be seen in the
test suite (which uses a plugin to exercise the code without relying
on specific warnings using this functionality).

Other output formats include
- JSON,
- printing each event as a separate "note", and
- to not emit paths.

d68f5d458d Replace label_text ctor with "borrow" and "take" 
libcpp's label_text class wraps a text buffer, along with a flag to
determine if it "owns" the buffer.

The existing ctor exposed this directly, but I found it difficult
to remember the sense of flag, so this patch hides the ctor, in
favor of static member functions "borrow" and "take", to make
the effect on ownership explicit in the name.

gcc/c-family/ChangeLog:
	* c-format.c (range_label_for_format_type_mismatch::get_text):
	Replace label_text ctor called with true with label_text::take.

gcc/c/ChangeLog:
	* c-objc-common.c (range_label_for_type_mismatch::get_text):
	Replace label_text ctor calls.

gcc/cp/ChangeLog:
	* error.c (range_label_for_type_mismatch::get_text): Replace
	label_text ctor calls with label_text::borrow.

gcc/ChangeLog:
	* gcc-rich-location.c
	(maybe_range_label_for_tree_type_mismatch::get_text): Replace
	label_text ctor call with label_text::borrow.
	* gcc-rich-location.h (text_range_label::get_text): Replace
	label_text ctor called with false with label_text::borrow.

libcpp/ChangeLog:
	* include/line-map.h (label_text::label_text): Make private.
	(label_text::borrow): New.
	(label_text::take): New.
	(label_text::take_or_copy): New.

9158f0ba97 [linemap PATCH] Constify lookup 
https://gcc.gnu.org/ml/gcc-patches/2019-10/msg01080.html
looking up a line map takes a non-constant line_maps object, which is confusing.
This makes the caching fields mutable, so permits a constant object, as one might expect for a lookup.

	* include/line-map.h (struct maps_info_ordinary): Make cache
	mutable.
	(struct maps_info_macro): Likewise.
	(LINEMAPS_CACHE): Remove non-ref accessor. Constify ref accessor.
	(LINEMAPS_ORDINARY_CACHE, LINEMAPS_MACRO_CACHE): Likewise.
	(LINEMAPS_ORDINARY_MAP_AT, LINEMAPS_MACRO_MAP_AT): Use
	LINEMAPS_USED and LINEMAPS_MAP_AT.
	(linemap_lookup): Constify line_map arg.
	linemap.c (linemap_ordinary_map_lookup, linemap_macro_map_lookup):
	Constify line_map arg.

200a8e1a38 Fix ICE with #line directive (PR c/89410) 
PR c/89410 reports various issues with #line directives with very
large numbers; one of them is an ICE inside diagnostic-show-locus.c
when emitting a diagnostic at line 0xffffffff.

The issue is that the arithmetic in layout::calculate_line_spans to
determine if two line spans are sufficiently close to consolidate
was using the unsigned 32-bit linenum_type, which was overflowing
when comparing the line for the expanded location with those of
the location range (all on line 0xffffffff), leading to it
erroneously adding two spans for the same line, leading to an
assertion failure.

This patch fixes the ICE by generalizing the use of long long in
line-map.h's comparison function for linenum_type into a new
linenum_arith_t typedef, and using it here.

Doing so uncovered a second problem: the loop to print the lines
within the line_span for this case is infinite: looping from
0xfffffff upwards, overflowing to 0, and then never becoming
greater than 0xfffffff.  The patch fixes this by using linenum_arith_t
there also.

gcc/ChangeLog:
	PR c/89410
	* diagnostic-show-locus.c (layout::calculate_line_spans): Use
	linenum_arith_t when determining if two adjacent line spans are
	close enough to merge.

85204e23e2 Less verbose fix-it hints for missing header files (PR 87091) 
This patch tweaks maybe_add_include_fixit so that if we're emitting a note
about adding the header file, the note's primary location will be replaced
by that of the fix-it hint, to avoid repeating a location we've already
emitted (or one close to it).

For example, this simplifies:

  ../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:87:27: error: msg 1
  87 |       using vector = std::vector<_Tp, polymorphic_allocator<_Tp>>;
     |                           ^~~~~~
  ../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:87:22: note: msg 2
   73 | # include <debug/vector>
  +++ |+#include <vector>
   74 | #endif
  ....
   87 |       using vector = std::vector<_Tp, polymorphic_allocator<_Tp>>;
      |                      ^~~

to:

  ../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:87:27: error: msg 1
  87 |       using vector = std::vector<_Tp, polymorphic_allocator<_Tp>>;
     |                           ^~~~~~
  ../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:74:1: note: msg 2
   73 | # include <debug/vector>
  +++ |+#include <vector>
   74 | #endif

eliminating the repetition of line 87 in the note.

Doing so requires converting show_caret_p to a tri-state, to avoid
meaninglessly printing a caret for the first column in the next line
(and colorizing it):

  ../x86_64-pc-linux-gnu/libstdc++-v3/include/vector:74:1: note: msg 2
