As the allocate-2.c testcase shows, this change isn't 100% backwards compatible, one could have allocate and/or align functions that return an OpenMP allocator handle and previously it would call those functions and now would use those names as keywords for the modifiers. But it allows specify extra alignment requirements for the allocations. 2021-09-22 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.h (OMP_CLAUSE_ALLOCATE_ALIGN): Define. * tree.c (omp_clause_num_ops): Change number of OMP_CLAUSE_ALLOCATE arguments from 2 to 3. * tree-pretty-print.c (dump_omp_clause): Print allocator() around allocate clause allocator and print align if present. * omp-low.c (scan_sharing_clauses): Force allocate_map entry even for omp_default_mem_alloc if align modifier is present. If align modifier is present, use TREE_LIST to encode both allocator and align. (lower_private_allocate, lower_rec_input_clauses, create_task_copyfn): Handle align modifier on allocator clause if present. gcc/c-family/ * c-omp.c (c_omp_split_clauses): Copy over OMP_CLAUSE_ALLOCATE_ALIGN. gcc/c/ * c-parser.c (c_parser_omp_clause_allocate): Parse allocate clause modifiers. gcc/cp/ * parser.c (cp_parser_omp_clause_allocate): Parse allocate clause modifiers. * semantics.c (finish_omp_clauses) <OMP_CLAUSE_ALLOCATE>: Perform semantic analysis of OMP_CLAUSE_ALLOCATE_ALIGN. * pt.c (tsubst_omp_clauses) <case OMP_CLAUSE_ALLOCATE>: Handle also OMP_CLAUSE_ALLOCATE_ALIGN. gcc/testsuite/ * c-c++-common/gomp/allocate-6.c: New test. * c-c++-common/gomp/allocate-7.c: New test. * g++.dg/gomp/allocate-4.C: New test. libgomp/ * testsuite/libgomp.c-c++-common/allocate-2.c: New test. * testsuite/libgomp.c-c++-common/allocate-3.c: New test. |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
