--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Tue Jul 10 07:12:37 2018 New Revision: 262534 URL: https://gcc.gnu.org/viewcvs?rev=262534&root=gcc&view=rev Log: PR c++/86443 * gimplify.c (find_combined_omp_for): Add DATA argument, in addition to finding the inner OMP_FOR/OMP_SIMD stmt find non-trivial wrappers, BLOCKs with BLOCK_VARs, OMP_PARALLEL in between, OMP_FOR in between. (gimplify_omp_for): For composite loops, move outer OMP_{DISTRIBUTE,TASKLOOP,FOR,PARALLEL} right around innermost OMP_FOR/OMP_SIMD if there are any non-trivial wrappers. For class iterators add any needed clauses. Allow OMP_FOR_ORIG_DECLS to contain TREE_LIST for both the original class iterator and the "last" helper var. Gimplify OMP_FOR_PRE_BODY before the outermost composite loop, remember has_decl_expr from outer composite loops for the innermost OMP_SIMD in TREE_PRIVATE bit on OMP_FOR_INIT. gcc/c-family/ * c-omp.c (c_omp_check_loop_iv_r, c_omp_check_loop_iv): Allow declv to contain TREE_LIST for both the original class iterator and the "last" helper var. gcc/cp/ * semantics.c (handle_omp_for_class_iterator): Remove lastp argument, instead of setting *lastp turn orig_declv elt into a TREE_LIST. (finish_omp_for): Adjust handle_omp_for_class_iterator caller. * pt.c (tsubst_omp_for_iterator): Allow OMP_FOR_ORIG_DECLS to contain TREE_LIST for both the original class iterator and the "last" helper var. libgomp/ * testsuite/libgomp.c++/for-15.C: New test.
