openmp: Add alloc_align attribute to omp_aligned_*alloc and testcase for omp_realloc
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.
2021-10-01 Jakub Jelinek <jakub@redhat.com>
* omp.h.in (omp_aligned_alloc, omp_aligned_calloc): Add
__alloc_align__ (1) attribute.
* testsuite/libgomp.c-c++-common/alloc-9.c: New test.
