Dear lazydev, I'm writing an instrumentation pass that depends on AliasAnalysis. My getAnalysisUsage() looks as follows: 2453 void ThreadSanitizer::getAnalysisUsage(AnalysisUsage &AU) const { 2454 AU.addRequired<TargetData>(); 2455 AU.addRequired<AliasAnalysis>(); 2456 } and the pass initialization: 2668 char ThreadSanitizer::ID = 0; 2669

I'm attempting to add some support for hoisting/sinking of memory-using intrinsics in loops, and so I want to use MemoryDependenceAnalysis in LICM, but when I modify getAnalysisUsge to include this : virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesCFG(); AU.addRequired<DominatorTree>(); AU.addRequired<LoopInfo>();

Hi Alexander, I had the same error: sincos: /home/marcusmae/rpmbuild/BUILD/llvm/lib/VMCore/PassManager.cpp:635: void llvm::PMTopLevelManager::schedulePass(llvm::Pass*): Assertion `PI && "Expected required passes to be initialized"' failed. The solution was to add: PassRegistry &Registry = *PassRegistry::getPassRegistry(); initializeCore(Registry);

Hi, List, As you may know, BCC of android makes use of LLVM's major components. Its LTO actually selects some optimizations of LLVM. I found it can not only use "-functionattrs". I must first use -argpromotion first, or I end up this error: Pass 'Deduce function attributes' is not initialized. Verify if there is a pass dependency cycle. Required Passes: bcc:

I am trying to add an analysis pass as a FunctionPass, and let LICM (LoopPass) depends upon it. So in LICM.cpp, I have the following: virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesCFG(); AU.addRequired<DominatorTree>(); AU.addRequired<LoopInfo>(); AU.addRequiredID(LoopSimplifyID); AU.addRequired<AliasAnalysis>();

Thanks for your last reply. Could I understand the way to adding a pass (built into the llvm rather than dynamic loadable) includes: 1. Declaring a creator function for this pass 2. Implementing the creator function for this pass 3. Instantiating this pass and get a object of it 3. Register this pass into the PassRegistry Then, for a built-into bytecode pass, task 1(declaration of the

Thank you. The edit made no difference. I did a clean install and the same error is reported.

Have you tried to pass --enable-shared to configure? It works for me. $ opt -load /usr/local/lib/LLVMHello.dylib -help | grep hello -hello - Hello World Pass -hello2 - Hello World Pass (with getAnalysisUsage implemented) - xi On Aug 21, 2012, at 5:55 PM, Ashwin kumar <ashwinkumar18 at gmail.com> wrote: >

When migrating my project to 2.9, I've encountered a strange segfault where if a ModulePass's getAnalysisUsage adds LoopInfo and DominatorTree, then llvm::PMTopLevelManager::findAnalysisUsage will segfault. What's odd is that if I rearrange this (add required for DominatorTree before LoopInfo), it does not segfault. I realize that LoopInfo requires and preserves DominatorTree, but this

Thanks for the response. I do have assertions enabled, and none of them are getting hit. I did do a search of the mailing list for the past year (approximately) before writing my email, and what I found was that you should be allowed to use LoopInfo and other analysis function passes from a module pass, with the only difference being that getAnalysis is passed the function. The example code I

So I got very mixed results. With the CallGraphSCCPass, both `addRequired<DominatorTreeWrapperPass>` and `addRequired<MemoryDependenceAnalysis>` fail at runtime. The LLVM core has just two CallGraphSCCPasses and neither uses neither analyses, so it's hard to find a valid example. I transformed the pass into a ModulePass, using scc_iterator as shown in CGPassManager to process

Hi Michael, hi Duncan, yesterday I stumbled over something that might be related. At least I could also just be doing some initialization wrong or something in this direction... In my case, I hit a segfault in PassInfo::isAnalysisGroup() after PassManager.add(myModulePass) is called. My setup seems fairly simple, the attached code should reproduce the error. Compile with g++ test.cpp

Your constructor is not calling initializeTestMPPass(), and you're using RegisterPass which I think was deprecated in favor of INITIALIZE_PASS. You can look at, for example, lib/Transforms/Scalar/IndVarSimplify.cpp for examples of how to initialize, e.g. having "INITIALIZE_PASS_DEPENDENCY(LoopInfo)" sandwiched between BEGIN and END. Note that you'll want a forward declaration of

Hello folks, I wrote a transforming looppass for my project, opt --help can see it. I want clang to use my pass too, so that I don't have to compile to IR, opt, and then llc to binary manually. Now I am trying to add my pass to O2 by mimicking LICM pass. I add a line "MPM.add(createMyPass());" in PassManagerBuilder::populateModulePassManager, and got assertion fail "void

I suggest you build LLVM with assertions enabled - then you should get a helpful error message rather than a segfault. I think you are not allowed to
