--- Comment #1 from Robin Dapp <rdapp at gcc dot gnu.org> --- Just speculating but do we try to use a gather for the access here? One difference to before is that is_packed is now always computed but shouldn't matter for gather/scatter on your architecture. So maybe an if (gather_scatter_p) return true; in gcn_vectorize_support_vector_misalignment helps?
