Function Documentation

◆ computeExprForSpill()

static const DIExpression* computeExprForSpill ( const MachineInstr & MI )

static

Compute the new DIExpression to use with a DBG_VALUE for a spill slot.

This prepends DW_OP_deref when spilling an indirect DBG_VALUE.

◆ moveOperands()

static void moveOperands	(	MachineOperand *	Dst,
		MachineOperand *	Src,
		unsigned	NumOps,
		MachineRegisterInfo *	MRI
	)

static

Move NumOps MachineOperands from Src to Dst, with support for overlapping ranges.

If MRI is non-null also update use-def chains.
