[LLVMdev] Def_Use chain

Hi All

I extract Def_Use chain by following code:

for (Value::use_iterator i = F->use_begin(), e = F->use_end(); i != e; ++i)

  if (Instruction *Inst = dyn_cast<Instruction>(*i)) {

    errs() << "F is used in instruction:\n";

    errs() << *Inst << "\n";


Now, I want to distinguish the register name or memory variable that lead to
this data dependency.
