* gimplify.c (omp_add_variable): Use GOVD_PRIVATE | GOVD_EXPLICIT for VLA helper variables on target data even if not GOVD_FIRSTPRIVATE. (gimplify_scan_omp_clauses): For OMP_CLAUSE_USE_DEVICE_* use just GOVD_EXPLICIT flags. (gimplify_omp_workshare): For OMP_TARGET_DATA move all OMP_CLAUSE_USE_DEVICE_* clauses to the end of clauses chain. * omp-low.c (scan_sharing_clauses): For OMP_CLAUSE_USE_DEVICE_* call install_var_field with mask 11 instead of 3. (lower_omp_target): For OMP_CLAUSE_USE_DEVICE_* use pass (splay_tree_key) &DECL_UID (var) to build_sender_ref instead of var. gcc/c/ * c-typeck.c (c_finish_omp_clauses): For C_ORT_OMP OMP_CLAUSE_USE_DEVICE_* clauses use oacc_reduction_head bitmap instead of generic_head to track duplicates. gcc/cp/ * semantics.c (finish_omp_clauses): For C_ORT_OMP OMP_CLAUSE_USE_DEVICE_* clauses use oacc_reduction_head bitmap instead of generic_head to track duplicates. libgomp/ * target.c (gomp_map_vars_internal): For GOMP_MAP_USE_DEVICE_PTR perform the lookup in the first loop only if !not_found_cnt, otherwise perform lookups for it in the second loop guarded with if (not_found_cnt || has_firstprivate). * testsuite/libgomp.c/target-37.c: New test. * testsuite/libgomp.c++/target-22.C: New test.
