--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- It's similar to PR96698 where we had a nested cycle where a cycle PHI was fed by an induction. Here we're feeding the cycle PHI by another cycle PHI so the fancy detection of computing a latch value doesn't work since the def is both the PHI of a cycle _and_ the latch def (in PR96698 we were safe because the def was an induction, not clashing with data structures). I never liked the current code much but now have to think about sth more reliable and workable for SLP.
