FunctionPass * createMSP430ISelDag(MSP430TargetMachine &TM, CodeGenOpt::Level OptLevel)
createMSP430ISelDag - This pass converts a legalized DAG into a MSP430-specific DAG, ready for instruction scheduling.
FunctionPass * createMSP430BranchSelectionPass()
Returns an instance of the Branch Selection Pass.
