Dear folks, I am trying to handle function pointers at call graph, and I found that the CallGraphSCCPass makes function pointers as external node, which is actually an empty CallGraphNode (NULL pointer)? If I want to distinguish the function pointer types in the call graph (and I also want the SCC order in CallGraphSCCPass), can I do that easily? Or I have to inheritate the CallGraphSCCPass and ha...

Hi, I've written a CallGraphSCCPass that compiles successfully, but when I try to run it with opt, it fails: Symbol not found: __ZTIN4llvm16CallGraphSCCPassE If I simply change the pass to be a FunctionPass or a ModulePass, opt can run it just fine. I'm on Mac OS X, so I thought perhaps I was running into bug #2771 [1...

Hi, I'm trying to use CallGraphSCCPass, but I keep getting a bus error. I can reproduce the problem quite easily using the lib/Transforms/Hello example. I simply mix in these changes: #include "llvm/CallGraphSCCPass.h" ... struct Hello : public CallGraphSCCPass { static char ID; // Pass identification, replacement...

Hi, I am writing a CallGraphSCCPass that uses LoopInfo which is a FunctionPass. However, doing so results in the following error. **** Unable to schedule 'Natural Loop Information' required by '......' **** Google led me to this page, where Devang Patel suggests implementing the addLowerLevelRequiredPasses in CGPassM...

Hi, I'm trying to use analysis results from a CallGraphSCCPass in a ModulePass. Here is the relevant code: struct MyCallGraphSCCPass : CallGraphSCCPass { ... bool runOnSCC(CallGraphSCC& scc){...} }; char MyCallGraphSCCPass::ID = 0; static RegisterPass<MyCallGraphSCCPass> X("cgscc", "Dummy CG SCC pass"); struct MyModule...

Hi, I have a FunctionPass that needs to process functions in bottom-up order on the call graph (callees before callers). CallGraphSCCPass can provide this ordering, but there's a snag. My pass depends on other passes, such as UnifyFunctionExitNodes and LoopInfo, to process the functions first. With a FunctionPass, I can specify these dependencies in FunctionPass::getAnalysisUsage, but if I convert the pass to a CallGrap...

Thanks John. Does this solve the problem of analysis availability though? If I still have to run the function analyses manually, I might as well keep rolling with the CallGraphSCCPass. (I probably should have mentioned that this is what I’m using right now.)

So I got very mixed results. With the CallGraphSCCPass, both `addRequired<DominatorTreeWrapperPass>` and `addRequired<MemoryDependenceAnalysis>` fail at runtime. The LLVM core has just two CallGraphSCCPasses and neither uses neither analyses, so it's hard to find a valid example. I transformed the pass into a ModulePass, using scc_iter...

Dear all, I would like to use the PostDominatorTree in ArgPromotion. I did not find an example of how to use function level analysis inside CallGraphSCCPass. I tried to follow an example of how to use function-level pass in a module pass, but I hit "llvm_unreachable" in PMDataManager::addLowerLevelRequiredPass. What would be a proper way to make PostDominatorTree available in ArgPromotion? Thanks in advance, Mikhail -------------- next par...

Hi Jakob, I have been trying to learn how the CodeGen passes work and I am playing around with the -debug-pass option. I tried implementing a bare CallGraphSCCPass based Pass in the CodeGen which basically does nothing for now. I mostly tried to replicate what RegAlloc passes do. I did this instead of modifying the existing RegAlloc passes to use CallGraphSCCPass because that was becoming way too complicated for simple experiments I was trying when I tried to...

...not to inline if a call instruction is unlikely to be executed). The problem here is that it is not possible to compute control dependency relationship between the annotated branch instruction and callsites using PostDominatorTree, because PostDominatorTree is a function pass and SimpleInliner is a CallGraphSCCPass. Is there any walk around for this issue? Thanks, Taewook -------------- next part -------------- An HTML attachment was scrubbed...
