--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- So this is another case where single-element (in this case strided) accesses go not VMAT_ELEMENTWISE where alignment is irrelevant but instead we use VMAT_STRIDED_SLP which isn't exempt from alignment requirements but it handles this case just fine. VMAT_INVARIANT has a similar issue. I have a fix for this.
