Hi, You need to initialize your pass with: INITIALIZE_PASS_BEGIN(YourPass, "your-pass", "Your Pass", /*cfgonly=*/false, /*analysis=*/false) INITIALIZE_PASS_DEPENDENCY(PostDominatorTreeWrapperPass) INITIALIZE_PASS_END(YourPass, "your-pass", "Your Pass", /*cfgonly=*/false, /*analysis=*/false) So as to both register your pass, and ha...

Hi everyone, I write a new FunctionPass which wants to use pass PostDominatorTree, so I implement the next function: void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<PostDominatorTree>(); AU.setPreservesAll(); } Then I get PDT through the next statement: PostDominatorTree *PDT = &getAnalysis<PostDominatorTree>(); My code can be successfully

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

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

That pass, in turn, requires other analysis, so I must Usually you want to do this at a higher level, why not just use 'opt -yourpass -mem2reg'? Alternatively, if you don't want to do that, you can build mem2reg into your pass if it works better. To do this, your pass needs to 'addRequired' DominatorTree and DominatorFrontier, then use the interfaces exposed through include/llvm/Transforms/Utils/PromoteMemToReg....

You can also see the resulting module by using -disable-verify: $ opt -yourpass -disable-verify < file.bc | llvm-dis You may see what the problem is by looking at the LLVM assembly. -- Misha Brukman :: http://misha.brukman.net :: http://llvm.cs.uiuc.edu

Because my pass must first modify the code, then run mem2reg pass and then do some more work. There's absolutely no way it could work without mem2reg pass. (That's the value analysis path I talked about earlier). > Alternatively, if you don't want to do that, you ca...

Hello, in the implementation of some analysis, I need to change the program and then invoke Mem2Reg pass. That pass, in turn, requires other analysis, so I must use PassManager. Here's the code I ended up with: bool runOnFunction(llvm::Function& m) { visit(m); ExistingModuleProvider mp(m.getParent());

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

Sorry to keep dragging this out on you. Im now getting: Assertion failed: (ResultPass && "getAnalysis*() called on an analysis that was not " "'required' by pass!"), function getAnalysisID But I already have: void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<DominatorTree>(); } And changed the bottom of my pass too: char Hello::ID =
