I had considered that, but my FunctionPass depends on other passes  
processing the functions first:

void MyPass::getAnalysisUsage(AnalysisUsage &AU) const {

bool MyPass::runOnFunction(Function &function) {
     LoopInfo &loopInfo = getAnalysis<LoopInfo>();

I don't know how to convert the above code into its equivalent form  
for a ModulePass.
