--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- Author: rguenth Date: Mon Dec 14 15:26:24 2015 New Revision: 231619 URL: https://gcc.gnu.org/viewcvs?rev=231619&root=gcc&view=rev Log: 2015-12-14 Richard Biener <rguent...@suse.de> PR tree-optimization/68852 * tree-vectorizer.h (struct _slp_tree): Add def_type member. (SLP_TREE_DEF_TYPE): New accessor. * tree-vect-stmts.c (vect_is_simple_use): Remove BB vectorization hack. * tree-vect-slp.c (vect_create_new_slp_node): Initialize SLP_TREE_DEF_TYPE. (vect_build_slp_tree): When a node is to be built up from scalars do not push a NULL as child but instead set its def_type to vect_external_def. (vect_analyze_slp_cost_1): Check for child def-type instead of NULL. (vect_detect_hybrid_slp_stmts): Likewise. (vect_bb_slp_scalar_cost): Likewise. (vect_get_slp_defs): Likewise. (vect_slp_analyze_node_operations): Likewise. Before processing node push the children def-types to the underlying stmts vinfo and restore it afterwards. (vect_schedule_slp_instance): Likewise. (vect_slp_analyze_bb_1): Do not mark stmts not in SLP instances as not vectorizable. * g++.dg/torture/pr68852.C: New testcase. Added: trunk/gcc/testsuite/g++.dg/torture/pr68852.C Modified: trunk/gcc/ChangeLog trunk/gcc/testsuite/ChangeLog trunk/gcc/tree-vect-slp.c trunk/gcc/tree-vect-stmts.c trunk/gcc/tree-vectorizer.h
