--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- So the question is whether we can make vect_compute_data_ref_alignment vectype agnostic (to also fix the required same vectype for multi SLP nodes covering the same DRs) and instead make DR_MISALIGNMENT a function we pass vectype (and an element offset?) to, computing whether the step maintains alignment on the fly (and have the offset specify that "N-1 elements before the address" we do for negative step)? Basically only record info for the scalar access. Specifically I wonder whether this will work to determine the base_misaligned info and realigning the base.
