--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- Author: rguenth Date: Wed Jul 17 10:26:25 2019 New Revision: 273549 URL: https://gcc.gnu.org/viewcvs?rev=273549&root=gcc&view=rev Log: 2019-07-17 Richard Biener <rguent...@suse.de> PR tree-optimization/91178 * tree-vect-stmts.c (get_group_load_store_type): For SLP loads with a gap larger than the vector size always use VMAT_STRIDED_SLP. (vectorizable_load): For VMAT_STRIDED_SLP with a permutation avoid loading vectors that are only contained in the gap and thus are not needed. * gcc.dg/torture/pr91178.c: New testcase. Added: trunk/gcc/testsuite/gcc.dg/torture/pr91178.c Modified: trunk/gcc/ChangeLog trunk/gcc/testsuite/ChangeLog trunk/gcc/tree-vect-stmts.c
