This patch allows 'declare mapper' mappers to be used on 'omp target data', 'omp target enter data' and 'omp target exit data' directives. For each of these, only explicit mappings are supported, unlike for 'omp target' directives where implicit uses of variables inside an offload region might trigger mappers also. Add support for C and C++. The patch also adjusts 'map kind decay' to match OpenMP 5.2 semantics, which is particularly important with regard to 'exit data' operations. gcc/c-family/ * c-common.h (c_omp_region_type): Add C_ORT_EXIT_DATA, C_ORT_OMP_EXIT_DATA. (c_omp_instantiate_mappers): Add region type parameter. * c-omp.cc (omp_split_map_kind, omp_join_map_kind, omp_map_decayed_kind): New functions. (omp_instantiate_mapper): Add ORT parameter. Implement map kind decay for instantiated mapper clauses. (c_omp_instantiate_mappers): Add ORT parameter, pass to omp_instantiate_mapper. gcc/c/ * c-parser.cc (c_parser_omp_target_data): Instantiate mappers for 'omp target data'. (c_parser_omp_target_enter_data): Instantiate mappers for 'omp target enter data'. (c_parser_omp_target_exit_data): Instantiate mappers for 'omp target exit data'. (c_parser_omp_target): Add c_omp_region_type argument to c_omp_instantiate_mappers call. * c-tree.h (c_omp_instantiate_mappers): Remove spurious prototype. gcc/cp/ * parser.cc (cp_parser_omp_target_data): Instantiate mappers for 'omp target data'. (cp_parser_omp_target_enter_data): Instantiate mappers for 'omp target enter data'. (cp_parser_omp_target_exit_data): Instantiate mappers for 'omp target exit data'. (cp_parser_omp_target): Add c_omp_region_type argument to c_omp_instantiate_mappers call. * pt.cc (tsubst_omp_clauses): Instantiate mappers for OMP regions other than just C_ORT_OMP_TARGET. (tsubst_expr): Update call to tsubst_omp_clauses for OMP_TARGET_UPDATE, OMP_TARGET_ENTER_DATA, OMP_TARGET_EXIT_DATA stanza. * semantics.cc (cxx_omp_map_array_section): Avoid calling build_array_ref for non-array/non-pointer bases (error reported already). gcc/testsuite/ * c-c++-common/gomp/declare-mapper-15.c: New test. * c-c++-common/gomp/declare-mapper-16.c: New test. * g++.dg/gomp/declare-mapper-1.C: Adjust expected scan output. |

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.
