Hi!
As noted by Richi, in clang INT_MIN / -1 is instrumented under
-fsanitize=signed-integer-overflow rather than
-fsanitize=integer-divide-by-zero as we did and doing it in the former
makes more sense, as it is overflow during division rather than division
by zero.

Support merging of profiles that are built from a different .o files
but belong to the same source file. Moreover, a checksum is verified
during profile merging and so we can safely combine such profile.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Looks like I tested the change for bb-slp-pr97709.c on an

While OpenMP 5.1 implies order(concurrent) is the same thing as

essentially order(concurrent) means nothing is stated on whether it is

Hi!
This patch adds alloc_align attribute to omp_aligned_{,c}alloc so that if
the first argument is constant, GCC can assume requested alignment.
Additionally, it adds testsuite coverage for omp_realloc which I haven't
managed to write in the patch from yesterday.

The new function-abi.cc module, so I'd rather have a correct prototype.

Hi,
this is a regression present on mainline, 11 and 10 branches: on bare-metal
platforms, the Ada compiler emulates stack checking (it is required by the
language and tested by ACATS) in the runtime via the stack_check_libfunc hook
of the RTL middle-end. Calls to the function are generated

The GCC development branch is open for general development (Stage 1),

When inlining we have to avoid mapping a non-lvalue parameter
