--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Thu Sep 25 08:19:14 2014 New Revision: 215587 URL: https://gcc.gnu.org/viewcvs?rev=215587&root=gcc&view=rev Log: PR tree-optimization/63341 * tree-vectorizer.h (vect_create_data_ref_ptr, vect_create_addr_base_for_vector_ref): Add another tree argument defaulting to NULL_TREE. * tree-vect-data-refs.c (vect_create_data_ref_ptr): Add byte_offset argument, pass it down to vect_create_addr_base_for_vector_ref. (vect_create_addr_base_for_vector_ref): Add byte_offset argument, add that to base_offset too if non-NULL. * tree-vect-stmts.c (vectorizable_load): Add byte_offset variable, for dr_explicit_realign_optimized set it to vector byte size - 1 instead of setting offset, pass byte_offset down to vect_create_data_ref_ptr. * gcc.dg/vect/pr63341-1.c: New test. * gcc.dg/vect/pr63341-2.c: New test.
