The follwing is a snippet of code to find some indirect calls in a module, which I learned from TopDownClosure.cpp: void FPS::repairCallGraph(Module &M) { CompleteBUDataStructures &DS = getAnalysis<CompleteBUDataStructures>(); for (Module::iterator f = M.begin(); f != M.end(); ++f ) { if( f->isExternal() ) continue; for (Function::iterator I = f->begin(); I != f->end(); ++I) { for(BasicBlock::iterator J = I->begin(); J != I->end(); ++J) {...

...to use the poolallocator. More specific, I am trying to play around with the pointer compression pass. Though, I get assertion failures for the pass dependencies. This is when it in PointerCompress::getAnalysisUsage tries to register the the BU pass as required.
