[PATCH] D109676: [HardwareLoops] put +1 for loop count before zero extension

[Sam Parker via Phabricator via llvm-commits]

samparker added a comment.

As I said previously, the behaviour of the intrinsics should better defined and then this transform should adhere to those semantics. We're already using different pairs of intrinsics for each backend, so this shouldn't be a problem; however, we may have to ensure the Arm backend rejects the 'old' set.loop.iterations just to be safe.
