[PATCH] D79175: [ARM][MVE] Tail-Predication: use @llvm.get.active.lane.mask to get the BTC

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Maybe instead of querying SCEV about `(((ElementCount + (VectorWidth - 1)) / VectorWidth) - TripCount`, it would be easier for SCEV to reason about `((ElementCount + (VectorWidth - 1)) - TripCount * VectorWidth`?
