similar to: [LLVMdev] Error while making new pass

Hi Devang, GlobalModRefPass is also a ModulePass and it uses CallGraph Analysis. So, I think it should not necessary to extend CallGraphSCCPass to use CallGraph information. Module Pass shoule be sufficient... --Kapil On 10/8/08, Devang Patel <dpatel at apple.com> wrote: > Hi Kapil, > > On Oct 8, 2008, at 10:19 AM, kapil anand wrote: > >> Hi all, >> >> I

Module Pass shoule be sufficient... ok, but you're Registering your pass in CallGraph Analysis group. What if you remove

HI Devang, Initially I had not added this pass to the group and I got this error regarding PassManager. I added the pass to group just to check whether that removes the error or not... I have removed it again. Is there any other registration required to configure pass manager for the pass? --Kapil On Wed, Oct 8, 2008 at 2:37 PM, Devang Patel <dpatel at apple.com> wrote: > > On

Hi, I have made my optimization as an extension of ModulePass as suggested in last mail. I included "addRequired<CallGraph>" in getAnalysisUsage function. The application compiles fine but while linking, I get following errors: "undefined reference to llvm::CallGraphLinkVar" "undefined reference to llvm::CallGraph::ID The above error is at point where I refer to

Hi, I have been working on implementing new analysis for a LLVM module. For that, I need that Call Graph of the module. Inside the CallGraph file, the constructor has been declared "protected" hence I can't define its instance and thus use the CallGraph for further analysis. So, what are the ways of building and using Call Graph of a module. Do I need to make my new analysis as

Hi all, I am implementing a new pass for LLVM which extends Call Graph SCCPass. I need DominatorTree Information when I get to individual function. I have added AU.addrequired<DominatorTree>() and AU.addRequired<DominanceFrontier>() in getAnalysisUsage() function. But, when I get to the pass, Pass Manager gives following runtime error Unable to schedule 'Dominator Tree

Hi, I am not making this application part of LLVM library although I do link the libLLVMipa library ( actually I am using llvm-config --libs all option in the Makefile which links all the libraries). Is it necessary to make it part of LLVM library? Thanks for you responses. --Kapil On Fri, Aug 22, 2008 at 3:40 PM, Bill Wendling <isanbard at gmail.com> wrote: > On Aug 21, 2008, at

Hello, I'm writing a Function Pass. This function pass needs access to the CallGraph and CallGraph SCCs. Is there any way I can get CallGraph information without changing my pass to a CallGraphSCCPass ? Thanks, -- Nick Johnson

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 for typeid Hello() : CallGraphSCCPass(&ID) {}

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_iterator as shown in CGPassManager to process

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.) Félix > Le 2015-05-19 à 10:12:32, John Criswell <jtcriswel at gmail.com> a écrit : > > On 5/18/15 10:45 PM, Félix Cloutier

But I'm not sure if using a FunctionPass to access Callgraph data is a good

Hi ! In my quest of implementing my own AA, i understood that it doesn't work because i don't use the 'opt' tool but i create my own PassManager (this for other reasons). The problem is the same with other existing AA (AndersensPass or globalModRefPass) : these AApasses are not chained with the basicAA when they are created in PassManager ... So my question is now : how to

Hi all, I am experimenting to run a pass inherited from CallGraphSCCPass. In the pass, I iterate all functions in a SCC. In each iteration, I access all arguments of a function in the following way: Function::arg_iterator PI = fun->arg_begin(), PE = fun->arg_end(); ... I have no trouble with building. However, I am troubled with "segmentation fault" when I run the pass
