virtual const TargetRegisterInfo& llvm::MSP430InstrInfo::getRegisterInfo ( ) const

inlinevirtual

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).
