Member Function Documentation

unsigned InstrEmitter::CountResults ( SDNode * Node ) [static]

CountResults - The results of target nodes have register or immediate operands first, then an optional chain, and optional flag operands (which do not go into the machine instrs.)

CountResults - The results of target nodes have register or immediate operands first, then an optional chain, and optional glue operands (which do not go into the resulting MachineInstr).
