--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
There's also

  if (memory_access_type =3D=3D VMAT_GATHER_SCATTER && gs_info.decl)
    {
      vect_build_gather_load_calls (vinfo, stmt_info, gsi, vec_stmt, &gs_in=
fo,
                                    mask, cost_vec);
      return true;

which doesn't support SLP either (but ICEs).=
