--- Comment #16 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
With new polymorphic call code we could handle the testcase from comment 15 by
simple propagation of contextes down during early optimization. This may be
easy enough to be worth to implement.

Still general solution is to add return functions to ipa-prop.
