--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
Fixed.  The reverse remains, so we currently cannot vectorize int[long] or
char[int] with emulated gather (but the more elements we get the less efficient
it will be).

It would be nice to transition x86 over to internal function gathers
(thus [mask_]gather_load and [mask_]scatter_store optabs, away from the
target hook returing a builtin decl).  If somebody can cover the .md
part (write define_expands) I'll take over the vectorizer part which
unfortunately isn't a no-op.
