--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think elsewhere I proposed the "proper" checking involving
POINTERS_EXTEND_UNSIGNED and checking for ptr_mode <-> Pmode/word_mode
but that doesn't cover memory address-spaces with different modes
since there we do not know whether to sign- or zero-extend.
