I *think* it should be fine, but I can double-check.



================
Comment at: llvm/lib/Target/AArch64/AArch64TargetMachine.cpp:484
       // pseudos then (v. addPreSched2()).
-      ScheduleDAGMI *DAG = createGenericSchedPostRA(C);
       DAG->addMutation(createAArch64MacroFusionDAGMutation());
       return DAG;
----------------
Might make sense to move the code from `AArch64MacroFusion.cpp` to the new `"AArch64MachineScheduler.h"`
