--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> --- Ok, again slpeels incredibly fragile manual SSA updating which relies on PHI nodes to appear in exactly the same order... which is AFAIK why I at some point removed that lc-PHI handling bail-out I re-added. We can't rely on update-ssa to perform it.
