--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- IMO we should eliminate SSA walking from those helpers in favor of using an active ranger (if a ranger is active, SSA walking should be OK) or falling back to global SSA info. Adding a valueize hook would work as well, of course (even if just as a flag to tell not to walk SSA...)
