--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> --- Author: rguenth Date: Thu Jun 18 09:39:13 2015 New Revision: 224598 URL: https://gcc.gnu.org/viewcvs?rev=224598&root=gcc&view=rev Log: 2015-06-18 Richard Biener <rguent...@suse.de> PR tree-optimization/66510 * tree-vect-stmts.c (vectorizable_load): Properly compute the number of vector loads for SLP permuted loads. * tree-vect-data-refs.c (vect_compute_data_ref_alignment): Also check the stride for loop vectorization. (vect_enhance_data_refs_alignment): Deal with SLP adjusted vectorization factor. (vect_analyze_group_access): If the group size is not a power of two require a epilogue loop. * tree-vect-loop.c (vect_analyze_loop_2): Move alignment compute and optimizing and alias test pruning after final vectorization factor computation. * tree-vect-slp.c (vect_build_slp_tree_1): Remove check on vector alignment. (vect_transform_slp_perm_load): Properly compute the original number of vector load stmts. * gcc.dg/vect/slp-perm-12.c: New testcase.
