◆ collectRegDefs()

static void collectRegDefs	(	const MachineInstr &	MI,
		DefinedRegsSet &	Regs,
		const TargetRegisterInfo *	TRI
	)

static

Collect all register defines (including aliases) for the given instruction.

◆ isRegOtherThanSPAndFP()

static bool isRegOtherThanSPAndFP	(	const MachineOperand &	Op,
		const MachineInstr &	MI,
		const TargetRegisterInfo *	TRI
	)

static

If Op is a stack or frame register return true, otherwise return false.

This is used to avoid basing the debug entry values on the registers, since we do not support it at the moment.
