Author: irar Date: Mon Apr 19 09:10:45 2010 New Revision: 158506 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=158506 Log: PR tree-optimization/37027 * tree-vectorizer.h (struct _loop_vec_info): Add new field reductions and macro to access it. (vectorizable_reduction): Add argument. (vect_get_slp_defs): Likewise. * tree-vect-loop.c (vect_analyze_scalar_cycles_1): Collect reduction statements for possible use in SLP. (new_loop_vec_info): Initialize LOOP_VINFO_REDUCTIONS. (destroy_loop_vec_info): Free LOOP_VINFO_REDUCTIONS. (vect_create_epilog_for_reduction): Handle SLP. Modify documentation, add new argument. (vectorizable_reduction): Likewise. * tree-vect-stmts.c (vect_get_vec_defs): Update call to vect_get_slp_defs. (vectorizable_type_demotion, vectorizable_type_promotion, vectorizable_store): Likewise. (vect_analyze_stmt): Update call to vectorizable_reduction. (vect_transform_stmt): Likewise. * tree-vect-slp.c (vect_get_and_check_slp_defs): Handle reduction. (vect_build_slp_tree): Fix indentation. Check that there are no loads from different interleaving chains in same node. (vect_slp_rearrange_stmts): New function. (vect_supported_load_permutation_p): Allow load permutations for reductions. Call vect_slp_rearrange_stmts() to rearrange statements inside SLP nodes if necessary. (vect_analyze_slp_instance): Handle reductions. (vect_analyze_slp): Try to build SLP instances originating from groups of reductions. (vect_detect_hybrid_slp_stmts): Skip reduction statements. (vect_get_constant_vectors): Create initial vectors for reductions according to reduction code. Add new argument. (vect_get_slp_defs): Add new argument, pass it to vect_get_constant_vectors. (vect_schedule_slp_instance): Remove SLP tree root statements.
