--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- While it was not intended that this patch causes code generation changes I think it can cause more PRE code hoisting since we never "iterated" that. Possibly, just a wild guess. Should be observable in PRE dumps, looking for changes in "Inserting expression in block %d for code hoisting".
