Hi all, Why are these two passes conflicting: UnifyFunctionExitNodes and LowerSwitch? AU.addRequired(LowerSwitchID) works, so does AU.addRequired<unifyFunctionExitNodes>(), but the two together don't... opt: PassManagerT.h:387: void llvm::PassManagerT<Trait>::markPassUsed(const llvm::PassInfo*, llvm::Pass*) [with Trait = llvm::MTraits]: Assertion `getAnalysisOrNullUp(P) && dynamic_cast<ImmutablePass*>(getAnalysisOrNullUp(P)) && "Pass available but not found!

Hi Thanks for all your feedback. I just found the reason for the compile failure for my analysis pass: I had to add my object to the namespace llvm instead of anonymous. This took me some time since i was looking for an linking failure... but as errors go i should have looked at the error message a little closer. So for all those trying to add an analysis path: * add the object name to the

...de needs modification to work. However, I thought that maybe I could just make them both ModulePasses instead, but that produces the following runtime error: opt: /home/mmccrack/lens/obj-llvm-darcslocal/../llvm-darcslocal/llvm/lib/VMCore/PassManagerT.h:426: void llvm::PassManagerT<UnitType>::markPassUsed(const llvm::PassInfo*, llvm::Pass*) [with UnitType = llvm::Module]: Assertion `getAnalysisOrNullUp(P) && dynamic_cast<ImmutablePass*>(getAnalysisOrNullUp(P)) && "Pass available but not found!

...which we then call addToPassManager() so we can get the right call to addPass(FP, ...), which adds FP to a single Batcher, in this case, a PassManagerT<FunctionPass>. In addPass(MP, ...) we see the FP in the required set, and attempt to mark it as used by the MP. We don't find it in markPassUsed though, because FP was never added to CurrentAnalyses. It was just added to the Batcher. So here's some changes that look necessary. This is likely to be an oversimplified view, but hopefully it's a start. 1 - in add(), discover that the pass we're requiring is a subpass, and creat...

...f. Attached file is the simplest possible example of Passes A, B, and C, such that C's getAnalysisUsage(AU) method calls AU.addRequired<A>() and AU.addRequired<B>(). When I try to run opt -load ... -opt-c, it tells me: opt: PassManagerT.h:348: void PassManagerT<UnitType>::markPassUsed (const PassInfo *, Pass *) [with UnitType = Module]: Assertion `Parent != 0 && "Pass available but not found!"' failed. I don't grok this error message. Of course, -opt-a and -opt-b both work fine in isolation. -- Casey Carter Casey at Carter.net ccarter at uiuc.edu AI...
