◆ getPassName()

StringRef AMDGPUAsmPrinter::getPassName ( ) const

overridevirtual

getPassName - Return a nice clean name for a pass.

This usually implemented in terms of the name that is registered by one of the Registration templates, but can be overloaded directly.

◆ isBlockOnlyReachableByFallthrough()

bool AMDGPUAsmPrinter::isBlockOnlyReachableByFallthrough ( const MachineBasicBlock * MBB ) const

overridevirtual

Return true if the basic block has exactly one predecessor and the control transfer mechanism between the predecessor and this block is a fall-through.

isBlockOnlyReachableByFallthough - Return true if the basic block has exactly one predecessor and the control transfer mechanism between the predecessor and this block is a fall-through.

◆ lowerConstant()

const MCExpr * AMDGPUAsmPrinter::lowerConstant ( const Constant * CV )

overridevirtual

Lower the specified LLVM Constant to an MCExpr.

The AsmPrinter::lowerConstantof does not know how to lower addrspacecast, therefore they should be lowered by this function.

◆ lowerOperand()

bool AMDGPUAsmPrinter::lowerOperand	(	const MachineOperand &	MO,
		MCOperand &	MCOp
	)		const

Wrapper for MCInstLowering.lowerOperand() for the tblgen'erated pseudo lowering.

◆ PrintAsmOperand()

bool AMDGPUAsmPrinter::PrintAsmOperand	(	const MachineInstr *	MI,
		unsigned	OpNo,
		const char *	ExtraCode,
		raw_ostream &	O
	)

overridevirtual

Print the specified operand of MI, an INLINEASM instruction, using the specified assembler variant.

PrintAsmOperand - Print the specified operand of MI, an INLINEASM instruction, using the specified assembler variant.

Targets should override this to format as appropriate. This method can return true if the operand is erroneous.

Targets should override this to format as appropriate for machine specific ExtraCodes or when the arch-independent handling would be too complex otherwise.
