getDeprecatedInfo()

bool MCInstrInfo::getDeprecatedInfo	(	MCInst &	MI,
		const MCSubtargetInfo &	STI,

getName()

StringRef llvm::MCInstrInfo::getName ( unsigned Opcode ) const

inline

Returns the name for the instructions with the given opcode.

Definition at line 69 of file MCInstrInfo.h.

getOpRegClassID()

int16_t llvm::MCInstrInfo::getOpRegClassID ( const MCOperandInfo & OpInfo, unsigned HwModeId ) const

inline

Return the ID of the register class to use for OpInfo, for the active HwMode HwModeId.
