示例2: ReplaceUsesOfBlockWith

/// ReplaceUsesOfBlockWith - Given a machine basic block that branched to
/// 'Old', change the code and CFG so that it branches to 'New' instead.
void MachineBasicBlock::ReplaceUsesOfBlockWith(MachineBasicBlock *Old,
                                               MachineBasicBlock *New) {
  assert(Old != New && "Cannot replace self with self!");

  MachineBasicBlock::instr_iterator I = instr_end();
  while (I != instr_begin()) {
    --I;
    if (!I->isTerminator()) break;

    // Scan the operands of this machine instruction, replacing any uses of Old
    // with New.
    for (unsigned i = 0, e = I->getNumOperands(); i != e; ++i)
      if (I->getOperand(i).isMBB() &&
          I->getOperand(i).getMBB() == Old)
        I->getOperand(i).setMBB(New);
  }

  // Update the successor information.
  replaceSuccessor(Old, New);
