--- Comment #4 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
indeed, this is a testcase for return functions in ipa-prop.  All other
solutions would need iteration and be fragile/unreliable.

-funroll-loops does not seem to have any effect on the second testcase for me. 
We end up with direct call to one() and two() there.
