Hello I am working on pass which has dependency on multiple passes. Say D1,D2,D3 I used INITIALIZE_PASS_BEGIN INITIALIZE_PASS_DEPENDENCY(D1) INITIALIZE_PASS_DEPENDENCY(D2) INITIALIZE_PASS_DEPENDENCY(D3) INITIALIZE_PASS_END. While running it through opt tool it, I had to specify this D1,D2,D3 pass names to get this pass executed before my pass. Is there way, to let llvm pass manager to know execute all dependencies without havi...

Does anyone know what the guidelines are supposed to be for properly initializing a pass? Looking around, we seem to have three styles of pass registration in use. INITIALIZE_PASS(...) INITIALIZE_PASS_BEGIN(...) INITIALIZE_PASS_DEPENDENCY(...) ... INITIALIZE_PASS_END(...) static RegisterPass<FooPass> X(...); (This is the one encouraged in the docs, but seemingly the least widely used in tree?) As far as I can tell, these often appear to work interchangeably. (At least for passes with only "well known" depende...

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 initializeTestMPPass(), as it won't have a declaration in include/llvm/InitializePasses.h. These are all the changes I think I had to make to port my passes to 2.9 from 2.8. On Wed, May 4,...

...uot;getAnalysis*() called on an analysis that was not " "'required' by pass!"), function getAnalysisID I do not know why. 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 declarations What is the correct way todo this?

Hi Mikhail, As Brian noted, stuff like this works better in the new pass manager. Even in the old pass manager I thought it should work though. Did you initialize the pass, via `INITIALIZE_PASS_DEPENDENCY(PostDominatorTreeWrapperPass)`? Did you require it, via ` AU.addRequired<PostDominatorTreeWrapperPass>();`? Btw. May I ask what you are planning to do? Cheers, Johannes On 01/07, Brian Gesiak via llvm-dev wrote: > Hello! The new pass manager provides analysis proxies from one IR...

Hi all, I am getting the infamous error: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not " "'required' by pass!"' but i really don't understand why. I have: voidInstrumentationPass::getAnalysisUsage(llvm::AnalysisUsage&AU) const{     AU.setPreservesAll();     AU.addRequired<DetectKernelsPass>();    

...itch over to that, but this is going to be frustrating when I'll need call graph SCC information. Anyone has a better idea? I should note that I'm not using the INITIALIZE_PASS macros because I have no idea how they mesh with RegisterPass. I'm seeing that the passes that use these have INITIALIZE_PASS_DEPENDENCY macros and it makes me a little nervous, but the resulting function for my pass is seemingly never called.
