I had considered that, but my FunctionPass depends on other passes processing the functions first: void MyPass::getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<UnifyFunctionExitNodes>();

Hi, I have a module pass and I hope to use it to optimize a real-world program. I need LTO，and I have got LTO plugin. But How can I add my passes to LTO Pass. I can't find solution.

Hi, Is there any facility in LLVM to identify recursion in a call graph? I realize this is undecidable in the general case due to function pointers, but at least the static cases could be identified. I don't even care about whole-program recursion, just looking at a single module would suffice. But I don't see anything like this already in LLVM, so do I simply write some code to
