--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #6) > Or, couldn't e.g. number of iterations analysis if it determines linear IV > adjust the value range? It indeed could if it's just the PHI that is lacking. OTOH niter analysis generally computes the number of iterations of an exit, not of a PHI node. OTOH the sprintf pass could simply compute value-ranges...
