Hi! I am trying to develop an LLVM tool which can apply different optimizations for selected functions. For example, I want to apply an optimization onto one function but not for another one. I am using the standard optimizations available in LLVM. That is the runOnModule function I have written: bool ComplNewBBFuncs::runOnModule(Module &M) { Function *Main =

...ePass { bool runOnModule(mod) { for some Functions f in mod { (do some stuff) ExistingModuleProvider mp(mod); FunctionPassManager* fpm = new FunctionPassManager(&mp); fpm->add(createLowerSwitchesPass()); fpm->add(createBreakCriticalEdgesPass()); fpm->add(createLoopSimplifyPass()); fpm2->run(*f); mp.releaseModule(); (do more stuff) } } } Now what I want to have is some runtime-output of the pass manager that tells me what passes were run in what order, give me timing information if possible etc. I hope my explanation is better this time :). Cheers, Ralf

Hey Daniel, thanks for the response. > I believe all you need to do is call llvm::llvm_shutdown(). > I am not sure that this is what I need. When and how should I call llvm_shutdown()? After the FunctionPassManager is done, the calling ModulePass still performs quite a few actions on the transformed code and also calls the FunctionPassManager on different functions. However, I need
