...afe, but there are mutexes and locking used in the code. This is actually creating a problem, because of a subtle bug involving static initialization order and shutdown. In particular, the RegisterPass<> static template will get invoked during static initialization and call PassRegistry::getPassRegistry()->registerPass(*this); Note that PassRegistry, however, is a ManagedStatic. So the call to getPassRegistry() creates the backing object of the ManagedStatic here. Then registerPass gets called, which attempts to lock the mutex. This will initialize the backing object of the SmartRWMutex. D...

...he new one has various benefits over legacy and wanted to clarify on something. Does creating the static RegisterPass struct register the pass with the new PassManager? It seems that RegisterPass does the same things that the INITIALIZE_PASS_* macros do but it registers the pass with PassRegistry::getPassRegistry(). What I'm not sure of is if this uses the new PassManager infrastructure. Exploring the code doesn't seem to show that this PassRegistry touches anything in the legacy namespace, but I wanted double confirmation on this. Thanks, Leonard

I added your suggestion and am using this now llvm::legacy::FunctionPassManager *functionPassManager = new llvm::legacy::FunctionPassManager(Mod); llvm::PassRegistry &registry = *llvm::PassRegistry::getPassRegistry(); initializeScalarOpts(registry); functionPassManager->add( new llvm::TargetLibraryInfoWrapperPass(llvm::TargetLibraryInfoImpl(targetMachine->getTargetTriple())) ); still, LV: The Widest register is: 32 bits. so, unfortunately no change.

The problems happens because PMTopLevelManager::findAnalysisPassInfo(AnalysisID AID) returns nullptr in PMTopLevelManager::addImmutablePass(ImmutablePass *P). This because PassRegistry::getPassRegistry()->getPassInfo(AID) call in it returns nullptr as well. Should I probably register the pass I want to add with PassRegistry::registerPass(const PassInfo &PI, bool ShouldFree) ? I didn’t do it because llc doesn’t do it either. Here is the assertion: Assertion failed: (PassInf && &quo...

I'm confused by your code. StaticInitializer seems to exist so you can create InitializeEverything, which doesn't get used. Do I need to do something along the lines of: static void registerPollyPasses(const llvm::PassManagerBuilder &Builder, llvm::PassManagerBase &PM) { PM.add(llvm::createPromoteMemoryToRegisterPass());

Hi, I'm writing a function pass which is dynamically loaded by opt and I need some analysis and passes to be run before my pass: virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.addPreserved<LoopInfo>(); AU.addRequiredID(LoopSimplifyID); AU.addPreservedID(LoopSimplifyID);

Are you sure you call getAnalysis only for the DominatorTree? What is the output of "grep getAnalysis YourPass.cpp"? Cheers Tobi

...in my pass. Assertion `AA && "AA didn't call InitializeAliasAnalysis in its run method!"' failed. Then, I tried to use INITIALIZE_PASS_XXXX or INITIALIZE_AG_PASS template, together with `*llvm::createMyMemDepPrinter()` and `initializeMemDepPrinterPass(*PassRegistry::getPassRegistry())` methods. Therefore, I got two compilation errors: MyMemDepPrinter.cpp:101:1: error: ‘void llvm::initializeMyMemDepPrinterPass(llvm::PassRegistry&)’ should have been declared inside ‘llvm’ MyMemDepPrinter.cpp:104:43: error: ‘llvm::FunctionPass* llvm::createMyMemDepPrinter()’ should...
