This creates a new predefined allocator as a shortcut for using pinned memory with OpenMP. The name uses the OpenMP extension space and is intended to be consistent with other OpenMP implementations currently in development. The allocator is equivalent to using a custom allocator with the pinned trait and the null fallback trait. libgomp/ChangeLog: * allocator.c (omp_max_predefined_alloc): Update. (predefined_alloc_mapping): Add ompx_pinned_mem_alloc entry. (omp_aligned_alloc): Support ompx_pinned_mem_alloc. (omp_free): Likewise. (omp_aligned_calloc): Likewise. (omp_realloc): Likewise. * omp.h.in (omp_allocator_handle_t): Add ompx_pinned_mem_alloc. * omp_lib.f90.in: Add ompx_pinned_mem_alloc. * testsuite/libgomp.c/alloc-pinned-5.c: New test. * testsuite/libgomp.c/alloc-pinned-6.c: New test. * testsuite/libgomp.fortran/alloc-pinned-1.f90: New test.
