--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Supposedly for TYPE_USER_ALIGN we could use TYPE_ALIGN_UNIT, but for other types we need to use min_align_of_type, otherwise we mishandle e.g. long long on i?86, which has TYPE_ALIGN_UNIT of 8, but when in struct is only 4 byte aligned, thus we can't assert 8 byte alignment for all long long * dereferences.
