how to add a ModulePassManager in llvm pass? - clang

Question

I'm trying to add a ModulePassManager in llvm pass, because all pass is function pass, so all I added createModuleToFunctionPassAdaptor function, but compile error, I don't know how to solve it. does anybody know how to solve this problem. I tried this:
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());
}
below is the compile error
