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).
