Member Function Documentation

◆ emitInstruction()

void PPCELFStreamer::emitInstruction	(	const MCInst &	Inst,
		const MCSubtargetInfo &	STI
	)

overridevirtual

Emit the given Instruction into the current section.

Reimplemented from llvm::MCObjectStreamer.

Definition at line 85 of file PPCELFStreamer.cpp.

References llvm::MCObjectStreamer::emitInstruction(), Emitter, llvm::MCObjectStreamer::getAssembler(), llvm::MCAssembler::getEmitterPtr(), and llvm::isPartOfGOTToPCRelPair().

◆ emitLabel()

void PPCELFStreamer::emitLabel	(	MCSymbol *	Symbol,
		SMLoc	Loc = `SMLoc()`
	)

overridevirtual

Emit a label for Symbol into the current section.

This corresponds to an assembler statement such as: foo:

Parameters

Symbol - The symbol to emit. A given symbol should only be emitted as a label once, and symbols emitted as a label should never be used in an assignment.

Reimplemented from llvm::MCELFStreamer.
