2017-05-03 Richard Biener <rguenther@suse.de>
* tree-vect-data-refs.c (vect_enhance_data_refs_alignment):
When all DRs have unknown misaligned do not always peel
when there is a store but apply the same costing model as if
there were only loads.
* gcc.dg/vect/costmodel/x86_64/costmodel-alignpeel.c: New testcase.
