dmgreen requested review of this revision.
Herald added a project: LLVM.

This adds an Mask ArrayRef to getShuffleCost, so that if an exact mask can be provided, a more accurate cost can be provided by the backend. For example VREV costs could be returned by the ARM backend. This should be an NFC until then, laying the groundwork for that to be added.
