[PATCH] D22194: Power9 - Add exploitation of oris/ori fusion

[Matthias Braun via llvm-commits]

MatzeB added a comment.

Can you explain why you need a custom mutator here? At first glance it looks like overriding TargetInstrInfo::shouldScheduleAdjacent() and using the default MacroFusion mutator is enough.
