[PATCH] D109631: [HardwareLoops] Loop guard intrinsic to recognise zext

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

> The int_loop.ll example compiles to a hardware loop with ARM's WLS instruction, while short_loop.ll does not and includes a loop guard. With this patch the short_loop.ll example also compiles to a WLS loop since the loop guard intrinsic is used.

Can you add a test then?
