HI I am try to run my new pass and it is giving the following error message while running: opt: loop_graph_new.cpp:265: void ::LoopGraphAnalysisPass::AddDataEdges(llvm::Loop , unsigned int): Assertion `loopGraph != graphs.end()' failed. 0 opt 0x000000000193137e llvm::sys::PrintStackTrace(_IO_FILE) + 46 1 opt 0x000000000193163b 2 opt 0x00000000019318ae 3 libpthread.so.0 0x00007fc5c4040340 4 libc.so.6 0x00007fc5c3054cc9 gsignal + 57 5 libc.so.6 0x00007fc5c30580d8 abort + 328 6 libc.so.6 0x00007fc5c304db86 7 libc.so.6 0x00007fc5c304dc32 8 loop_graph_analysis_abc.so 0x00007fc5c2e1796f 9 loop_graph_analysis_abc.so 0x00007fc5c2e17873 10 loop_graph_analysis_abc.so 0x00007fc5c2e177ad 11 opt 0x0000000001898c5b llvm::FPPassManager::runOnFunction(llvm::Function&) + 427 12 opt 0x0000000001898f68 llvm::FPPassManager::runOnModule(llvm::Module&) + 104 13 opt 0x000000000189962a 14 opt 0x000000000189921e llvm::legacy::PassManagerImpl::run(llvm::Module&) + 302 15 opt 0x0000000001899ad1 llvm::legacy::PassManager::run(llvm::Module&) + 33 16 opt 0x0000000000657ca2 main + 6706 17 libc.so.6 0x00007fc5c303fec5 __libc_start_main + 245 18 opt 0x0000000000649219 Stack dump: 0.

  1. Running pass 'Function Pass Manager' on module 'matrix.bc'.
  2. Running pass 'form program graphs and analyze' on function '@main'

Aborted (core dumped)

Is this error is due to loopID.

The error is in the following AddDataEdges function which is being called from ProcessLoop() :

bool ProcessLoop(Loop* L/, ProfileInfo& PI/) { //ENTRY_POINT("ProcessLoop"); printf("ProcessLoop\n"); for (Loop::iterator I = L->begin(), E = L->end(); I != E; ++I) ProcessLoop(I/, PI*/);

map <unsigned int, double>::iterator topLoopIter =

topLoops.find(loopID);

        //introduce data dependence edges into graph
        AddDataEdges(L, loopID);

void AddDataEdges (Loop* L, unsigned int id) { //ENTRY_POINT("AddDataEdges"); printf("AddDataEdges\n"); //get loop graph map <unsigned int, clust_graph>::iterator loopGraph = graphs.find (id); assert (loopGraph != graphs.end());

     //for each node
    for (map<Value*, clust_node>::iterator nodeIter =

loopGraph->second.begin(); nodeIter != loopGraph->second.end(); nodeIter ++)

Please help.

Thanks, Manideepa
