clang - 如何在 llvm 通行证中添加 ModulePassManager？

问题描述

我正在尝试在llvm pass中添加一个ModulePassManager，因为所有pass都是函数pass，所以我都添加了createModuleToFunctionPassAdaptor函数，但是编译出错，我不知道如何解决。有谁知道如何解决这个问题。我试过这个：

llvm::PreservedAnalyses DBogusFlow::run(llvm::Module &M,
                                        llvm::ModuleAnalysisManager &MAM) {
  bool Changed = runOnModule(M);

  auto MPM = std::make_unique<ModulePassManager>();

  MPM->addPass(createModuleToFunctionPassAdaptor(createAggressiveDCEPass()));
  MPM->addPass(
      createModuleToFunctionPassAdaptor(createInstructionCombiningPass()));
  MPM->addPass(
      createModuleToFunctionPassAdaptor(createCFGSimplificationPass()));
  MPM->run(M, MAM);

  return (Changed ? llvm::PreservedAnalyses::none()
                  : llvm::PreservedAnalyses::all());
}

下面是编译错误
