tree-vect-stmts.c (get_group_load_store_type): If the access is aligned do not trigger peeling for gaps.
2016-11-08 Richard Biener <rguenther@suse.de>
* tree-vect-stmts.c (get_group_load_store_type): If the
access is aligned do not trigger peeling for gaps.
* tree-vect-data-refs.c (vect_compute_data_ref_alignment): Do not
force alignment of vars with DECL_USER_ALIGN.
* gcc.dg/vect/vect-nb-iter-ub-2.c: Adjust.
