Hello All, I wanted to know how to use -callgraph option provided with opt. I have been using a -print-callgraph for generating a CG but I don't want the o/p to go to a dot file. Is it required to build a pass using CallGraph.cpp or we can directly use the option with a .bc file. Thanks SHWETA -------------- next part -------------- An HTML attachment was scrubbed... URL:

I am finding some weird behavior in the CallGraph, and am not sure what am I doing wrong. When trying to traverse nodes in the CallGraph I get stuck in nodes representing external functions. Take the following code: ----- #include <stdio.h> int main() { printf( "Hello World!\n" ); } ----- If I try to traverse the CallGraph using the following code: ----- CallGraph CG

Dear everyone, I want to traverse call graph, but I have some trouble . In my pass MyPass which need to traverse call graph, I firstly added the CallGraph analysis to the pass requirements by *AU.addRequired<CallGraph>();* My pass MyPass then will be added to a pass manager by *manager.add(new MyPass());* and then I want to traverse the call graph such as: CallGraph CG =

Hello, I want an instance of CallGraph in my pass. By looking at -dot-callgraph source, I've tried something like this: CallGraphWrapperPass *CGWP = new CallGraphWrapperPass(); PM.add(CGWP); CallGraph *CG = &CGWP->getCallGraph(); PM.add(new MyPass(CG)); I get the following error: /home/riyad/installs/llvm-3.7.0/include/llvm/PassSupport.h:95:38: error: no matching constructor for

Hello: We are working with LLVM-3.1 and we have a problem.This is the code we have executed: virtual void getAnalysisUsage( llvm::AnalysisUsage & info ) const { info.addRequired<CallGraph>(); ... } ... virtual bool runOnModule( Module & M ) { ... CallGraph &CG = this->getAnalysis<CallGraph>(); CallGraphNode *cgn; unsigned nref;

I recall having a similar problem while coding my own special-purpose "opt". My guess: try adding the following lines before your pass is inserted into the PassManager: PassRegistry &Registry = *PassRegistry::getPassRegistry(); initializeIPA(Registry); You might require other library initializations. Have a look at the "opt" source code. On 02/12/13 10:36,

Hi all, I want to find all the called functions in each function, thus I iterate the calledFunctions of each CallGraphNode in CallGraph as follow: for (CallGraph::iterator it = CG->begin(); it != CG->end(); ++it) { CallGraphNode* node = it->second; for (CallGraphNode::iterator it2 = node->begin(); it2 != node->end(); ++it2) { Function* calledFunc =

Hello, On the following code, // #include <stdio.h> void f2(); int main(){ f2(); return 0; } void f2(){ printf("f2()\n"); } // I have obtained the .bc file and run opt -print-callgraph finename.bc. For the main function, the output of the above command is: Call graph node for function: 'main' Calls external node However, the function called by

Dear Ashutosh, Thank you, I can handle some indirect callSites by getFunction() of InvokInst and CallInst. However, when I am handling C++ programs, I found the calls of member functions are converted to some strange indirect calls. For example: table->truncate(sysTransaction); // from mysql are translated to the next complex llvm IR: _ZN8Database20getSystemTransactionEv.exit: ;

So, I won't know the called function statically, Right? -------------------------------------------- Qiuping Yi Institute Of Software Chinese Academy of Sciences On Wed, Jan 20, 2016 at 2:24 PM, Nema, Ashutosh <Ashutosh.Nema at amd.com> wrote: > Typically for C++ virtual function you will see an indirect callSite > (unless not de-virtualized). > > > > Regards, >

no .. i am calling a function pass from a module pass, adding other function passes to my module pass works, but when i try to add MemoryDependenceAnalysis it gives error I want to report a bug but i don't know if this is a real bug or i am doing something wrong, knowing that i am adding other function passe to my module pass and it works fine. the error i get: adding callgraph pass ...
