When predicitive commoning moves an invariant ref it makes sure to
not build a MEM_REF with a base that is negatively offsetted from
an object.  But in trying to preserve some transforms it does not
consider association of a constant offset with the address computation
in DR_BASE_ADDRESS leading to exactly this problem again.  This is
arguably a problem in data-ref analysis producing such an out-of-bound
DR_BASE_ADDRESS, but this looks quite involved to fix, so the
following avoids the association in one more case.  This fixes the
testcase while preserving the desired transform in
gcc.dg/tree-ssa/predcom-1.c.

	PR tree-optimization/118954
	* tree-predcom.cc (ref_at_iteration): Make sure to not

Binutils 2.24 was released in 2013, so this is more than 11 years old.

gcc:
	PR target/69374
	* doc/install.texi (Specific, aarch64*-*-*): Drop note for
	Binutils pre 2.24.

While looking at PR118956, I noticed that we had some dead code
left over after the removal of the vcond patterns.  The can_invert_p
path is no longer used.

gcc/
	* config/aarch64/aarch64-protos.h (aarch64_expand_sve_vec_cmp_float):
	Remove can_invert_p argument and change return type to void.
	* config/aarch64/aarch64.cc (aarch64_expand_sve_vec_cmp_float):
	Likewise.
	* config/aarch64/aarch64-sve.md (vec_cmp<mode><vpred>): Update call
	accordingly.

This test has been failing since r15-1619-g3b9b8d6cfdf593, which made
IRA prefer a call-clobbered register over a call-preserved register
for mem1 (the second load).  In this particular case, that just
forces the variable p3 to be allocated to a call-preserved register
instead, leading to an extra predicate move from p3 to that register.

However, it was really pot luck that this worked before.  Each argument
is used exactly once, so there isn't an obvious colouring order.
And mem0 and mem1 are passed by indirect reference, so they are not
REG_EQUIV to a stack slot in the way that some memory arguments are.

IIRC, the test was the result of some experimentation, and so I think
the best fix is to rework it to try to make it less sensitive to RA
decisions.  This patch does that by enabling scheduling for the
function and using both memory arguments in the same instruction.
This gets rid of the distracting prologue and epilogue code and
restricts the test to the PCS parts.

gcc/testsuite/
	PR testsuite/116604
	* gcc.target/aarch64/sve/pcs/args_1.c (callee_pred): Enable scheduling
	and use both memory arguments in the same instruction.  Expect no
	prologue and epilogue code.

gcc.target/aarch64/sve/var_stride_2.c started failing after
r15-268-g9dbff9c05520, but the change was an improvement:

This patch therefore changes the test to expect the new output
for var_stride_2.c.

The changes for var_stride_4.c were a wash, with both versions
having 18(!) arithmetic instructions before the alias check branch.
Both versions sign-extend the n and m arguments as part of this
sequence; the question is whether they do it first or later.

This patch therefore changes the test to accept either the old
or the new code for var_stride_4.c.

When SCCP does final value replacement we end up with unfolded IL like

__result_274 = _150 + 1;
...
__new_finish_106 = __result_274 + 3;  <-- from SCCP
_115 = _150 + 4;
if (__new_finish_106 != _115)

this does only get rectified by the next full folding which happens
in forwprop4 which is after the strlen pass emitting the unwanted
diagnostic.  The following mitigates this case in a similar way as
r15-7472 did for PR118817 - by ensuring we have the IL folded.
This is done by simply folding all immediate uses of the former
PHI def that SCCP replaces.  All other more general approaches have
too much fallout at this point.

Since r15-7511-g4e7f74225116e7 we can disable the warnings for using a

When linking statically to libstdc++.a (or to libstdc++_nonshared.a in
the RHEL devtoolset compiler) there's a static initialization order
problem where user code might be constructed before the
std::chrono::tzdb_list globals, and so might try to use them after
they've already been destroyed.

Use the init_priority attribute on those globals so that they are
initialized early. Since r15-7511-g4e7f74225116e7 we can disable the

The PR indicates a very specific issue with regard to SSA coalescing
failures because there's a pre IV increment loop exit test.  While
IVOPTs created the desired IL we later simplify the exit test into
the undesirable form again.  The following fixes this up during RTL

This reverts commit 565d4e75.

Even though 'iterator' is a reserved macro name, we can't use it as the
name of this implementation detail type since it could introduce name
lookup ambiguity in valid code, e.g.

  struct A { using iterator = void; }
  struct B : concat_view<...>, A { using type = iterator; };

Reviewed-by: Jonathan Wakely <jwakely@redhat.com>

Our concat_view implementation is accidentally based off of an older
revision of the paper, P2542R7 instead of R8.  As far as I can tell the
only semantic change in the final revision is the relaxed constraints on
the iterator's iter/sent operator- overloads, which this patch updates.

This patch also simplifies the concat_view::end wording via C++26 pack
indexing as per the final revision.  In turn we make the availability of
this library feature conditional on __cpp_pack_indexing.  (Note pack
indexing is implemented in GCC 15 and Clang 19).

..., where "support" means that the build doesn't fail, but it doesn't mean
that all target libraries get built and we get pretty test results for the
additional languages.

	* configure.ac (unsupported_languages) [GCN, nvptx]: Add 'ada'.
	(noconfigdirs) [GCN, nvptx]: Add 'target-libobjc',
	'target-libffi', 'target-libgo'.
	* configure: Regenerate.

gcc/testsuite/
	* gcc.target/avr/torture/isr-04-regs.c: New test.
	* gcc.target/avr/isr-test.h: Don't set GPRs to values
	that are 0 mod 0x11.

This testcase started to fail with r15-268-g9dbff9c05520a7.
When late_combine was added, it was turned on for -O2+ only,
so this testcase still failed.
This changes the option to be -O2 instead of -O and the testcase
started to pass again.

tested for aarch64-linux-gnu.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/pr112105.c: Change to be -O2 rather
	than -O1.

input.cc's file_cache was borrowing copies of the file name.
This could lead to use-after-free when writing out sarif output
from Fortran, which frees its filenames before the sarif output
is fully written out.

Fix by taking a copy in file_cache_slot.

gcc/ChangeLog:
	PR other/118919
	* input.cc (file_cache_slot::m_file_path): Make non-const.
	(file_cache_slot::evict): Free m_file_path.
	(file_cache_slot::create): Store a copy of file_path if non-null.
	(file_cache_slot::~file_cache_slot): Free m_file_path.

Previously the analyzer treated IFN_UBSAN_BOUNDS as a no-op, but
the other IFN_UBSAN_* were unrecognized and conservatively treated
as having arbitrary behavior.

Treat IFN_UBSAN_NULL and IFN_UBSAN_PTR also as no-ops, which should
make -fanalyzer behave better with -fsanitize=undefined.

gcc/analyzer/ChangeLog:
	PR analyzer/118300
	* kf.cc (class kf_ubsan_bounds): Replace this with...
	(class kf_ubsan_noop): ...this.
	(register_sanitizer_builtins): Use it to handle IFN_UBSAN_NULL,
	IFN_UBSAN_BOUNDS, and IFN_UBSAN_PTR as nop-ops.
	(register_known_functions): Drop handling of IFN_UBSAN_BOUNDS
	here, as it's now handled by register_sanitizer_builtins above.

gcc/testsuite/ChangeLog:
	PR analyzer/118300
	* gcc.dg/analyzer/ubsan-pr118300.c: New test.
