[LLVMdev] Assertion `PI && "Expected required passes to be initialized"' failed for AliasAnalysis.

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 INITIALIZE_PASS_BEGIN(ThreadSanitizer, "tsan",
2670                       "Compile-time instrumentation for runtime "
2671                       "data race detection with ThreadSanitizer",
2672                       false, false)
2673 INITIALIZE_PASS_DEPENDENCY(TargetData)
2674 INITIALIZE_AG_DEPENDENCY(AliasAnalysis)
2675 INITIALIZE_PASS_END(ThreadSanitizer, "tsan",
2676                     "Compile-time instrumentation for runtime "
2677                     "data race detection with ThreadSanitizer",
2678                     false, false)
2679


However when I run Clang with my pass enabled, I get the following error:
$ clang_build_Linux/Release+Asserts/bin/clang -fthread-sanitizer -c t.c

Do I need something besides INITIALIZE_AG_DEPENDENCY in order to
initialize AliasAnalysis? (I've verified that removing TargetData does
not fix the problem)

[LLVMdev] Assertion `PI && "Expected required passes to be initialized"' failed for AliasAnalysis.

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);
		initializeScalarOpts(Registry);
		initializeIPO(Registry);
		initializeAnalysis(Registry);
		initializeIPA(Registry);
		initializeTransformUtils(Registry);
		initializeInstCombine(Registry);
		initializeInstrumentation(Registry);
		initializeTarget(Registry);

before creating passes. Maybe it could help you to track down the issue.

- D.

[LLVMdev] Assertion `PI && "Expected required passes to be initialized"' failed for AliasAnalysis.

Adding initializeAnalysis() indeed helped:

2680 ModulePass *llvm::createThreadSanitizerPass() {
2681   PassRegistry &Registry = *PassRegistry::getPassRegistry();
2682   initializeAnalysis(Registry);
2683   return new ThreadSanitizer();
2684 }

This looks a bit awkward, but still allows me to move further.
Thanks a lot!
