--- Comment #35 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Note to self. This is the case dr_explicit_realign: case of vectorizable_load. (ptr + 12) & -16L - i.e. vs_minus_1 * TYPE_ALIGN_UNIT (element) is reasonable for the case where the original stmt data ref is naturally aligned, but in this case it is an unaligned load and thus we can't use + 12 but should use + 15 instead. This is quite related to PR63341, but that was the dr_explicit_realign_optimized case, not dr_explicit_realign.
