Hi! By only two cases I mean , that in exiting block when computing the condition related to PHI node I can expect only icmp on one of incoming values or on phi node itself... I tried to come up with some more complex examples but I always receive only these two cases, that is why I am asking. This problem still relates to the problem of all induction, cumulative and so on variables in loop. SCEV
