--- Comment #15 from Richard Biener <rguenth at gcc dot gnu.org> --- Author: rguenth Date: Mon Sep 28 10:45:55 2015 New Revision: 228199 URL: https://gcc.gnu.org/viewcvs?rev=228199&root=gcc&view=rev Log: 2015-09-28 Richard Biener <rguent...@suse.de> Backport from mainline 2015-08-03 Richard Biener <rguent...@suse.de> PR tree-optimization/66917 * tree-vectorizer.h (struct dataref_aux): Add base_element_aligned field. (DR_VECT_AUX): New macro. (set_dr_misalignment): Adjust. (dr_misalignment): Likewise. * tree-vect-data-refs.c (vect_compute_data_ref_alignment): Compute whether the base is at least element aligned. * tree-vect-stmts.c (ensure_base_align): Adjust. (vectorizable_store): If the base is not element aligned preserve alignment of the original access if misalignment is unknown. (vectorizable_load): Likewise. 2015-09-16 Richard Biener <rguent...@suse.de> PR middle-end/67442 * fold-const.c (extract_muldiv_1): Properly extend multiplication result before builting a tree via wide_int_to_tree. * gcc.dg/torture/pr67442.c: New testcase.
