--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The FE part is now implemented (and handling it in the middle end if there are
no pointer/reference arguments too), but improving handling of functions with
those attributes with pointer/reference arguments in the middle-end is still
not done.
