Methods

¶void InitMCInstrInfo(
    const llvm::MCInstrDesc* D,
    const unsigned int* NI,
    const char* ND,
    const uint8_t* DF,
    const llvm::MCInstrInfo::

¶const llvm::MCInstrDesc& get(
    unsigned int Opcode) const

Description

Return the machine instruction descriptor that corresponds to the specified instruction opcode.

Declared at: llvm/include/llvm/MC/MCInstrInfo.h:63

Parameters

unsigned int Opcode

¶bool getDeprecatedInfo(
    llvm::MCInst& MI,
    const llvm::MCSubtargetInfo& STI,
