[PATCH] D62907: [ARM] Implement TTI::isHardwareLoopProfitable

[Nico Weber via Phabricator via llvm-commits]

thakis added a comment.

All these tests seem to fail when the ARM target isn't enabled, with errors like this:

  ********************

      LLVM :: Transforms/HardwareLoops/ARM/simple-do.ll
      LLVM :: Transforms/HardwareLoops/ARM/structure.ll

They probably all need a `REQUIRES: arm-registered-target`?
