Function Documentation

static unsigned AddLiveIn	(	MachineFunction &	MF,
		unsigned	PReg,
		TargetRegisterClass *	RC
	)			[static]

AddLiveIn - This helper function adds the specified physical register to the MachineFunction as a live in value. It also creates a corresponding virtual register for it.
