openmp: Implement allocate clause in omp lowering. For now, task/taskloop constructs aren't handled and C/C++ array reductions and reductions with task or inscan modifiers need further work. Instead of calling omp_alloc/omp_free (where the former doesn't have alignment argument and omp_aligned_alloc is 5.1 only feature), this calls GOMP_alloc/GOMP_free, so that the library can fail if it would fall back into NULL (exception is zero length allocations). 2020-11-12 Jakub Jelinek <jakub@redhat.com> gcc/ * builtin-types.def (BT_FN_PTR_SIZE_SIZE_PTRMODE): New function type. * omp-builtins.def (BUILT_IN_GOACC_DECLARE): Move earlier.

openmp: Add support for non-VLA {,first}private allocate on omp task This patch adds support for custom allocators on private/firstprivate clauses for task (and taskloop) constructs. Private didn't need anything special, but firstprivate if it is passed by reference needs the GOMP_alloc calls in the copyfn and GOMP_free in the task body. 2020-11-14 Jakub Jelinek <jakub@redhat.com> * gimplify.c (gimplify_omp_for): Add OMP_CLAUSE_ALLOCATE_ALLOCATOR decls as firstprivate on task clauses even when allocate clause decl is not lastprivate. * omp-low.c (install_var_field): Don't dereference omp_is_reference types if mask is 33 rather than 1. (scan_sharing_clauses): Populate allocate_map even for task constructs. For now remove it back for variables mentioned in reduction and in_reduction clauses on task/taskloop constructs or on VLA task firstprivates. For firstprivate on task construct, install the var field into field_map with by_ref and 33 instead of false and 1 if mentioned in allocate clause. (lower_private_allocate): Set TREE_THIS_NOTRAP on the created MEM_REF. (lower_rec_input_clauses): Handle allocate for task firstprivatized non-VLA variables. (create_task_copyfn): Likewise. * testsuite/libgomp.c-c++-common/allocate-1.c (struct S): New type. (foo): Add tests for non-VLA private and firstprivate clauses on omp task. (bar): Likewise. Remove taking of address from private/firstprivate variables. * testsuite/libgomp.c++/allocate-1.C (struct S): New type. (foo): Add p, q, px and s arguments. Add tests for array reductions and for non-VLA private and firstprivate clauses on omp task. (bar): Removed. (main): Adjust foo caller. Don't call bar.

openmp: Add support for non-VLA {,first}private allocate on omp task This patch adds support for custom allocators on private/firstprivate clauses for task (and taskloop) constructs. Private didn't need anything special, but firstprivate if it is passed by reference needs the GOMP_alloc calls in the copyfn and GOMP_free in the task body. 2020-11-14 Jakub Jelinek <jakub@redhat.com> * gimplify.c (gimplify_omp_for): Add OMP_CLAUSE_ALLOCATE_ALLOCATOR decls as firstprivate on task clauses even when allocate clause decl is not lastprivate. * omp-low.c (install_var_field): Don't dereference omp_is_reference types if mask is 33 rather than 1. (scan_sharing_clauses): Populate allocate_map even for task constructs. For now remove it back for variables mentioned in reduction and in_reduction clauses on task/taskloop constructs or on VLA task firstprivates. For firstprivate on task construct, install the var field into field_map with by_ref and 33 instead of false and 1 if mentioned in allocate clause.
