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.

const TargetRegisterInfo& 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).
