gcc/c/ChangeLog:
* c-parser.c (struct omp_dim): New struct type for use inside
c_parser_omp_variable_list.
(c_parser_omp_variable_list): Allow multiple levels of array and
component accesses in array section base-pointer expression.
(c_parser_omp_clause_to): Set 'allow_deref' to true in call to
c_parser_omp_var_list_parens.
(c_parser_omp_clause_from): Likewise.
* c-typeck.c (handle_omp_array_sections_1): Extend allowed range
of base-pointer expressions involving INDIRECT/MEM/ARRAY_REF and
POINTER_PLUS_EXPR.
(c_finish_omp_clauses): Extend allowed ranged of expressions
involving INDIRECT/MEM/ARRAY_REF and POINTER_PLUS_EXPR.
gcc/cp/ChangeLog:
* parser.c (struct omp_dim): New struct type for use inside
cp_parser_omp_var_list_no_open.
(cp_parser_omp_var_list_no_open): Allow multiple levels of array and
component accesses in array section base-pointer expression.
(cp_parser_omp_all_clauses): Set 'allow_deref' to true in call to
cp_parser_omp_var_list for to/from clauses.
* semantics.c (handle_omp_array_sections_1): Extend allowed range
of base-pointer expressions involving INDIRECT/MEM/ARRAY_REF and
POINTER_PLUS_EXPR.
(handle_omp_array_sections): Adjust pointer map generation of
references.
(finish_omp_clauses): Extend allowed ranged of expressions
involving INDIRECT/MEM/ARRAY_REF and POINTER_PLUS_EXPR.
gcc/fortran/ChangeLog:
* trans-openmp.c (gfc_trans_omp_array_section): Do not generate
GOMP_MAP_ALWAYS_POINTER map for main array maps of ARRAY_TYPE type.
gcc/ChangeLog:
* gimplify.c (extract_base_bit_offset): Add 'tree *offsetp' parameter,
accomodate case where 'offset' return of get_inner_reference is
non-NULL.
(is_or_contains_p): Further robustify conditions.
(omp_target_reorder_clauses): In alloc/to/from sorting phase, also
move following GOMP_MAP_ALWAYS_POINTER maps along. Add new sorting
phase where we make sure pointers with an attach/detach map are ordered
correctly.
(gimplify_scan_omp_clauses): Add modifications to avoid creating
GOMP_MAP_STRUCT and associated alloc map for attach/detach maps.
gcc/testsuite/ChangeLog:
* c-c++-common/goacc/deep-copy-arrayofstruct.c: Adjust testcase.
* c-c++-common/gomp/target-enter-data-1.c: New testcase.
libgomp/ChangeLog:
* target.c (gomp_map_vars_existing): Make sure attached pointer is
not overwritten during cross-host/device copying.
(gomp_update): Likewise.
(gomp_exit_data): Likewise.
* testsuite/libgomp.c++/target-11.C: Adjust testcase.
* testsuite/libgomp.c++/target-12.C: Likewise.
* testsuite/libgomp.c++/target-15.C: Likewise.
* testsuite/libgomp.c++/target-16.C: Likewise.
* testsuite/libgomp.c++/target-17.C: Likewise.
* testsuite/libgomp.c++/target-21.C: Likewise.
* testsuite/libgomp.c++/target-23.C: Likewise.
* testsuite/libgomp.c/target-23.c: Likewise.
* testsuite/libgomp.c/target-29.c: Likewise.
