Member Function Documentation

void NVPTXFrameLowering::eliminateCallFramePseudoInstr	(	MachineFunction &	MF,
		MachineBasicBlock &	MBB,
		MachineBasicBlock::iterator	MI
	)		const [override, virtual]

eliminateCallFramePseudoInstr - This method is called during prolog/epilog code insertion to eliminate call frame setup and destroy pseudo instructions (but only if the Target is using them). It is responsible for eliminating these instructions, replacing them with concrete instructions. This method need only be implemented if using call frame setup/destroy pseudo instructions.

Reimplemented from llvm::TargetFrameLowering.

emitProlog/emitEpilog - These methods insert prolog and epilog code into the function.

bool NVPTXFrameLowering::hasFP

(

const MachineFunction &

MF

)

const [override, virtual]

hasFP - Return true if the specified function should have a dedicated frame pointer register. For most targets this is true only if the function has variable sized allocas or if frame pointer elimination is disabled.

Implements llvm::TargetFrameLowering.
