--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Some pending enhancements would allow us to use VEC_PERM_EXPR with different
input modes from output mode and thus make implementation of this easier.
vectorizable_slp_permutation doesn't yet support that though.
For the special case of a contiguous permutation we can also vectorize it
as BIT_FIELD_REF of course.
