--- Comment #1 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Would be possible to analyze this a bit? The patch does have effect on optimizers because we produce a lot fewer MEM_REFs on type mismatches. Of course this should not trigger wrong code but it also may be some bug in benchmark or so.
