Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2019-04-28 Ever confirmed|0 |1 --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- I think gimple_has_side_effects shouldn't return true for clobbers (and/or maybe we shouldn't set gimple_has_volatile_ops on them). Otherwise the patch looks sensible, mind to test/post it?
