'self_maps' implies 'unified_shared_memory', except that the latter also permits that explicit maps copy data to device memory while self_maps does not. In GCC, currently, both are handled identical. gcc/c/ChangeLog: * c-parser.cc (c_parser_omp_requires): Handle self_maps clause. gcc/cp/ChangeLog: * parser.cc (cp_parser_omp_requires): Handle self_maps clause. gcc/fortran/ChangeLog: * gfortran.h (enum gfc_omp_requires_kind): Add OMP_REQ_SELF_MAPS. (gfc_namespace): Enlarge omp_requires bitfield. * module.cc (enum ab_attribute, attr_bits): Add AB_OMP_REQ_SELF_MAPS. (mio_symbol_attribute): Handle it. * openmp.cc (gfc_check_omp_requires, gfc_match_omp_requires): Handle self_maps clause. * parse.cc (gfc_parse_file): Handle self_maps clause. gcc/ChangeLog: * lto-cgraph.cc (output_offload_tables, omp_requires_to_name): Handle self_maps clause. * omp-general.cc (struct omp_ts_info, omp_context_selector_matches): Likewise for the associated trait. * omp-general.h (enum omp_requires): Add OMP_REQUIRES_SELF_MAPS. * omp-selectors.h (enum omp_ts_code): Add OMP_TRAIT_IMPLEMENTATION_SELF_MAPS. include/ChangeLog: * gomp-constants.h (GOMP_REQUIRES_SELF_MAPS): #define. libgomp/ChangeLog: * plugin/plugin-gcn.c (GOMP_OFFLOAD_get_num_devices): Accept self_maps clause. * plugin/plugin-nvptx.c (GOMP_OFFLOAD_get_num_devices): Likewise. * libgomp.texi (TR13 Impl. Status): Set to 'Y'. * target.c (gomp_requires_to_name, GOMP_offload_register_ver, gomp_target_init): Handle self_maps clause. * testsuite/libgomp.fortran/self_maps.f90: New test. gcc/testsuite/ChangeLog: * c-c++-common/gomp/declare-variant-1.c: Add self_maps test. * c-c++-common/gomp/requires-4.c: Likewise. * gfortran.dg/gomp/declare-variant-3.f90: Likewise. * c-c++-common/gomp/requires-2.c: Update dg-error msg. * gfortran.dg/gomp/requires-2.f90: Likewise. * gfortran.dg/gomp/requires-self-maps-aux.f90: New. * gfortran.dg/gomp/requires-self-maps.f90: New. |

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.
