...beNegative = !SE->isKnownNonNegative(delta); I'm really happy with the power of the SCEVs, letting me answer these questions, but I'm unhappy with how the code reads, namely the double negatives. Perhaps we might introduce a handful of new methods, things like *bool ScalarEvolution::isPerhapsZero(const SCEV *S) {* * return !isKnownNonZero(S);* * }* Seem useful?
