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 <anonymous
namespace>::LoopGraphAnalysisPass::AddDataEdges(llvm::Loop *, unsigned
int): Assertion `loopGraph != graphs.end()' failed.

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
