--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
We can only do that if we have a guarantee the callee doesn't care about
whether it is automatic or static var and in the case where it isn't const also
a guarantee it doesn't modify it.  Both are the case for memcpy source of
course.
