Hi Guangming Tan, > I rewrote the code, please help check why it still does not work: next time please be more explicit about exactly what goes wrong. > //create a getelementptr instruction: we want get &Counters[OldCounterSize] > std::vector<Value*>new_idx; > new_idx.push_back(OldCounterSize); // ERROR? > Value *nextaddr = GetElementPtrInst::Create(Counters, new_idx.begin(), > new_idx.end(), "", InsertPos); You need to push an index of zero before pushing the OldCounterSize index. Ciao, Dunc...
