The corresponding part in SelectionDAGISel looks like this:
void SelectionDAGISel::Select_FREEZE(SDNode *N) {
// TODO: We don't have FREEZE pseudo-instruction in MachineInstr-level now.
// If FREEZE instruction is added later, the code below must be changed as
// well.
CurDAG->SelectNodeTo(N, TargetOpcode::COPY, N->getValueType(0),
N->getOperand(0));
}
