◆ getInstSizeInBytes()

unsigned MSP430InstrInfo::getInstSizeInBytes ( const MachineInstr MI) const

GetInstSize - Return the number of bytes of code the specified instruction may be.

This returns the maximum number of bytes.

◆ getRegisterInfo()

const MSP430RegisterInfo & llvm::MSP430InstrInfo::getRegisterInfo ( ) const
inline

getRegisterInfo - TargetInstrInfo is a superset of MRegister info.

As such, whenever a client has an instance of instruction info, it should always be able to get register info as well (through this method).
