Subject: [PATCH] c-parser.c (c_parser_oacc_declare): Add support for
GOMP_MAP_FIRSTPRIVATE_POINTER.
gcc/c/
* c-parser.c (c_parser_oacc_declare): Add support for
GOMP_MAP_FIRSTPRIVATE_POINTER.
* c-typeck.c (handle_omp_array_sections_1): Replace bool is_omp
argument with enum c_omp_region_type ort.
(handle_omp_array_sections): Likewise. Update call to
handle_omp_array_sections_1.
(c_finish_omp_clauses): Add specific errors and warning messages for
OpenACC. Use firsrtprivate pointers for OpenACC subarrays. Update
call to handle_omp_array_sections.
gcc/cp/
* parser.c (cp_parser_oacc_declare): Add support for
GOMP_MAP_FIRSTPRIVATE_POINTER.
* semantics.c (handle_omp_array_sections_1): Replace bool is_omp
argument with enum c_omp_region_type ort. Don't privatize OpenACC
non-static members.
(handle_omp_array_sections): Replace bool is_omp argument with enum
c_omp_region_type ort. Update call to handle_omp_array_sections_1.
(finish_omp_clauses): Add specific errors and warning messages for
OpenACC. Use firsrtprivate pointers for OpenACC subarrays. Update
call to handle_omp_array_sections.
gcc/
* gimplify.c (omp_notice_variable): Use zero-length arrays for data
pointers inside OACC_DATA regions.
(gimplify_scan_omp_clauses): Prune firstprivate clause associated
with OACC_DATA, OACC_ENTER_DATA and OACC_EXIT data regions.
(gimplify_adjust_omp_clauses): Fix typo in comment.
