--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
I wonder if there is an algorithm to fall back to that doesn't require
iteration.
Or, if not, if we can instead check if there was progress during the last
iteration (interpreting the limit as a way to check whether we'll iterate
indefinitely).
