I noticed the DeadStoreElimination pass also uses this, but it does not use RegisterPass (like mine and the docs show). Instead it has lines like:        INITIALIZE_PASS_DEPENDENCY(MemoryDependenceAnalysis) This gives me:        error: C++ requires a type specifier for all decl...

I have a transformation where I'd like to use both DominatorTree (for ExtractCodeRegion), and DemoteRegisterToMemory (i.e., reg2mem). The transformation is phased, so all occurrences of getAnalysis<DominatorTree>(Function) happen before any occurrence of getAnalysisID<FunctionPass>(&DemoteRegisterToMemoryID, Function). If I register these two passes with DominatorTree first, I get the following assert. PassAnalysisSupport.h:239: AnalysisType& llvm::Pass::getAnalysisID(const void*, llvm::Function&) [with AnalysisType = llvm::DominatorTree]: As...

Hi, Migrating from 3.5 to 3.9. There is a module pass that uses alias analysis started breaking at runtime: llvm/lnx64/llvm/include/llvm/PassAnalysisSupport.h:236: AnalysisType& llvm::Pass::getAnalysisID(llvm::AnalysisID) const [with AnalysisType = llvm::AAResultsWrapperPass; llvm::AnalysisID = const void*]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not " "'required' by pass!"' failed. What does this mean? I have this line in my...

The transformation is phased, so all occurrences of getAnalysis<DominatorTree>(Function) happen before any occurrence of getAnalysisID<FunctionPass>(&DemoteRegisterToMemoryID, Function). I believe that reg2mem is a transform pass, correct? If so, then you should not be making it a prerequisite for your pass. Instead, whatever is scheduling the set of transform passes (e.g, the user on the opt command line or the so...

Awesome, that let me get far enough to trip: Assertion failed: (ResultPass && "Unable to find requested analysis info"), function getAnalysisID Is there something else I forgot?

But this is already present in my pass. And I am not able to understand the cause for the error: opt: /home/ambika/llvm_3/llvm-2.6/include/llvm/PassAnalysisSupport.h:203: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*) const [with AnalysisType = llvm::DominatorTree]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not " "'required' by pass!"' failed. What can possibly cause this. Any ideas will also help. Tobias Grosser wr...

Hi, you need something like this in your pass: void YourPass::getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<DominatorTree>(); } because you need to specify which analysis you are using. Tobi
