...minatorTree-Information-required-in-CallGraphPass-td 21968640.html I tried this but to get analysis passes on the fly I need to use FunctionPassManagerImpl in CallGraphSCCPass.cpp which I cannot because it is not part of any header file. I tried using FunctionPassManager but it does not implement getOnTheFlyPass() required by getAnalysis(). I also tried putting CGPassManager in PassManager.cpp (and therefore in libLLVMCore.a ?) but the build failed due to a cyclic dependency between libLLVMCore.a, libLLVMAnalysis.a and libLLVMipa.a. Any pointers to resolving this would be greatly appreciated. Thanks in a...

Hi, I'm trying to use the function getAnalysis. This is the code I'm using : void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.setPreservesAll(); } virtual bool runOnModule(Module &M) { LoopInfo &LI = getAnalysis<LoopInfo>(); } I get following error when I try to run my pass : opt:

In runOnFunction(), you should check to see if the function F is a declaration before calling getAnalysis(F). Calling getAnalysis<FunctionPass>() on a function that is a declaration will trigger an assertion if the function is just a declaration. To see if a function is a declaration, call its isDeclaration() method (i.e. if (F->isDeclaration()) ... ) -- John T. On 10/13/11 8:09
