...wo loops is the loop exit condition, both semantically same. Scalar Evolution is unable to determine the exit value of the second loop, leading to the vectorizer failing to vectorize. It seemed to me that this is due to ScalarEvolution::SimplifyICmpOperands failing to canonicalize the corresponding ICMP_ULE instruction.
