There is one adjustment to a C++ test which now gives a false positive.
After talking with Martin Sebor, we've concluded this is expected. There
is no way to communicate that libstdc++ allocated objects are always
less than PTRDIFF_MAX.
gcc/ChangeLog:
* calls.c (get_size_range): Adjust to work with ranger.
* calls.h (get_size_range): Add ranger argument to prototype.
* gimple-ssa-warn-restrict.c (class wrestrict_dom_walker): Remove.
(check_call): Pull out of wrestrict_dom_walker into a
static function.
(wrestrict_dom_walker::before_dom_children): Rename to...
(wrestrict_walk): ...this.
(pass_wrestrict::execute): Instantiate ranger.
(class builtin_memref): Add stmt and query fields.
(builtin_access::builtin_access): Add range_query field.
(builtin_memref::builtin_memref): Same.
(builtin_memref::extend_offset_range): Same.
(builtin_access::builtin_access): Make work with ranger.
(wrestrict_dom_walker::check_call): Pull out into...
(check_call): ...here.
(check_bounds_or_overlap): Add range_query argument.
* gimple-ssa-warn-restrict.h (check_bounds_or_overlap):
Add range_query and gimple stmt arguments.
gcc/testsuite/ChangeLog:
* gcc.dg/Wrestrict-22.c: New test.
* g++.dg/torture/pr92421.C: Adjust for ranger.
libstdc++-v3/ChangeLog:
* testsuite/21_strings/basic_string/capacity/1.cc: Pass
-Wno-stringop-overflow to test.

In the r10-7197-gbae7b38cf8a21e068ad5c0bab089dedb78af3346 commit I've
noticed duplicated word in a message, which lead me to grep for those and
we have a tons of them.
I've used
grep -v 'long long\|optab optab\|template template\|double double' *.[chS] */*.[chS] *.def config/*/* 2>/dev/null | grep ' \([a-zA-Z]\+\) \1 '
Note, the command will not detect the doubled words at the start or end of
line or when one of the words is at the end of line and the next one at the
start of another one.
Some of it is fairly obvious, e.g. all the "the the" cases which is
something I've posted and committed patch for already e.g. in 2016,
other cases are often valid, e.g. "that that" seems to look mostly ok to me.
Some cases are quite hard to figure out, I've left out some of them from the
patch (e.g. "and and" in some cases isn't talking about bitwise/logical and
and so looks incorrect, but in other cases it is talking about those
operations).
In most cases the right solution seems to be to remove one of the duplicated
words, but not always.
I think most important are the ones with user visible messages (in the patch
3 of the first 4 hunks), the rest is just comments (and internal
documentation; for that see the doc/tm.texi changes).

We often emit logically-related groups of diagnostics.
A relatively simple case is this:
if (warning_at (body_loc, OPT_Wmultistatement_macros,
"macro expands to multiple statements"))
inform (guard_loc, "some parts of macro expansion are not guarded by "
"this %qs clause", guard_tinfo_to_string (keyword));
where the "note" diagnostic issued by the "inform" call
is guarded by the -Wmultistatement_macros warning.
More complicated examples can be seen in the C++ frontend,
where e.g. print_z_candidates can lead to numerous "note"
diagnostics being emitted.
I'm looking at various ways to improve how we handle such related
diagnostics, but, prior to this patch, there was no explicit
relationship between these diagnostics: the diagnostics subsystem
had no way of "knowing" that these were related.
This patch introduces a simple way to group the diagnostics:
an auto_diagnostic_group class: all diagnostics emitted within
the lifetime of an auto_diagnostic_group instance are logically
grouped.
Hence in the above example, the two diagnostics can be grouped
by simply adding an auto_diagnostic_group instance:
auto_diagnostic_group d;
if (warning_at (body_loc, OPT_Wmultistatement_macros,
"macro expands to multiple statements"))
inform (guard_loc, "some parts of macro expansion are not guarded by "
"this %qs clause", guard_tinfo_to_string (keyword));
Some more awkard cases are of the form:
if (some_condition
&& warning_at (...)
&& more_conditions)
inform (...);
which thus need restructuring to:
if (some_condition)
{
auto_diagnostic_group d;
warning_at (...);
if (more_conditions)
inform (...);
}
so that the lifetime of the auto_diagnostic_group groups the
warning_at and the inform call.
Nesting is handled by simply tracking a nesting depth within the
diagnostic_context.: all diagnostics are treated as grouped until the
final auto_diagnostic_group is popped.
diagnostic.c uses this internally, so that all diagnostics are part of
a group - those that are "by themselves" are treated as being part of
a group with one element.
The diagnostic_context gains optional callbacks for displaying the
start of a group (when the first diagnostic is emitted within it), and
the end of a group (for when the group was non-empty); these callbacks
are unused by default, but a test plugin demonstrates them (and verifies
that the machinery is working).
As noted above, I'm looking at various ways to use the grouping to
improve how we output the diagnostics.
FWIW, I experimented with a more involved implementation, of the form:
diagnostic_group d;
if (d.warning_at (body_loc, OPT_Wmultistatement_macros,
"macro expands to multiple statements"))
d.inform (guard_loc, "some parts of macro expansion are not guarded by "
"this %qs clause", guard_tinfo_to_string (keyword));
which had the advantage of allowing auto-detection of the places where
groups were needed (by converting ::warning_at's return type to bool),
but it was a much more invasive patch, especially when dealing with
the places in the C++ frontend that can emit numerous notes after
an error or warning (and thus having to pass the group around)
Hence I went with this simpler approach.

This patch allows MEM_REF offsets to be polynomial, with mem_ref_offset
now returning a poly_offset_int instead of an offset_int. The
non-mechanical changes to callers of mem_ref_offset were handled by

This patch changes the values returned by
get_addr_base_and_unit_offset from HOST_WIDE_INT to poly_int64.
maxsize in gimple_fold_builtin_memory_op goes from HOST_WIDE_INT
to poly_uint64 (rather than poly_int) to match the previous use
of tree_fits_uhwi_p.
