[PATCH] D24855: MachineScheduler: Enable macro fusion in post-RA scheduler

[Andrew Trick via llvm-commits]

atrick added a comment.

On x86 it's meant to be a heuristic. If you think all subtargets should instead force macro-fusion before scheduling (and have benchmarks to prove it) then we should delete the code that implements the heuristic.
