--- Comment #2 from Jan Hubicka <hubicka at gcc dot gnu.org> --- I am not able to reproduce those on gcc110.fsffrance.org. Would be possible to have -fdump-ipa-all -fdump-tree-all dumps of the devirt testcase? I think both are related to fast that ipa-prop is not propagating across the local aliases, but I do not see why the local aliases are introduced here at first place. Perhaps binds_local_p is somehow wrong for AIX?
