◆ ModuloScheduleExpander()

llvm::ModuloScheduleExpander::ModuloScheduleExpander	(	MachineFunction &	MF,
		ModuloSchedule &	S,
		LiveIntervals &	LIS,
		InstrChangesTy	InstrChanges )

inline

Create a new ModuloScheduleExpander.

InstrChanges Modifications to make to instructions with memory operands. FIXME: InstrChanges is opaque and is an implementation detail of an optimization in MachinePipeliner that crosses abstraction boundaries.
