--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- Author: rguenth Date: Tue Jun 6 07:37:14 2017 New Revision: 248909 URL: https://gcc.gnu.org/viewcvs?rev=248909&root=gcc&view=rev Log: 2017-06-06 Richard Biener <rguent...@suse.de> PR tree-optimization/80928 * tree-vect-loop.c (vect_update_vf_for_slp): Amend dumps. (vect_analyze_loop_operations): Properly guard analysis for pure SLP case. (vect_transform_loop): Likewise. (vect_analyze_loop_2): Also reset SLP type on PHIs. (vect_model_induction_cost): Do not cost for pure SLP. (vectorizable_induction): Pass in SLP node, implement SLP vectorization of induction in inner loop vectorization. * tree-vect-slp.c (vect_create_new_slp_node): Handle PHIs. (vect_get_and_check_slp_defs): Handle vect_induction_def. (vect_build_slp_tree): Likewise. Handle PHIs as terminating the recursion. (vect_analyze_slp_cost_1): Cost induction. (vect_detect_hybrid_slp_stmts): Handle PHIs. (vect_get_slp_vect_defs): Likewise. * tree-vect-stmts.c (vect_analyze_stmt): Handle induction. (vect_transform_stmt): Handle SLP reductions. * tree-vectorizer.h (vectorizable_induction): Adjust. * gcc.dg/vect/pr80928.c: New testcase. * gcc.dg/vect/slp-13-big-array.c: Remove XFAILs. * gcc.dg/vect/slp-13.c: Likewise. * gcc.dg/vect/slp-perm-9.c: Prevent vectorization of check loop.
