--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Richard Biener from comment #2) > So in theory we could record basic-block boundaries as DR group_id instead Note for outer loop vect we need the BB restriction which means we'd need to compute the group_id array also for loop vect.
