You are required to "add" passes, before running them, so that the
pass manager can schedule required analysis information properly.
In your case, you could try...
bool ComplNewBBFuncs::runOnModule(Module &M)
Function *Main = M.getFunction("main");
if (Main == 0)
cerr << "!!! No Main Function" << std::endl;
//Determine each Function
Function *CurFunc1 = M.getFunction("NewFunction1");
Function &Current1 = (*CurFunc1);
Function *CurFunc2 = M.getFunction("NewFunction2");
Function &Current2 = (*CurFunc2);
FPM2.add(createLoopUnrollPass()); /* This will setup loop pass
manager appropriately */
