示例#1

文件： cfg.cpp 项目： IshanRastogi/hhvm

BlockList rpoSortCfg(const IRUnit& unit) {
  BlockList blocks;
  blocks.reserve(unit.numBlocks());
  postorderWalk(unit,
    [&](Block* block) {
      blocks.push_back(block);
    });

  std::reverse(blocks.begin(), blocks.end());
  assert(blocks.size() <= unit.numBlocks());
  return blocks;
}
