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
