--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
That we do not optimize this is mostly an implementation issue as we do not
have
a way to annotate a call with dependence info. We'd have to grow gcall
to add this for example or somehow integrate / refactor this with the
call_used/clobbered sets already there (there's enough padding in those
structs, we could decompose them, combining them and providing accessors).
