Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |GC CC| |rguenth at gcc dot gnu.org, | |segher at gcc dot gnu.org --- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- Hmm, but shouldn't we instead fix combine to record not the reg rtx but the regno for UNDO_MODE? Because nothing prevents this from happening elsewhere (even in combine itself?).
