OK, I just need the same signature for both of those instructions.

I do something like this:

static bool areSame(Instruction *A, Instruction *B) {
  if (A->getOpcode() != B->getOpcode()) return false;
  if (A->getType()->getTypeID() != B->getType()->getTypeID()) return false;
  unsigned int a = A->getNumOperands();
  if (a != B->getNumOperands()) return false;
  for (unsigned int i = 0; i < a; ++i)
    if (A->getOperand(i)->getType()->getTypeID()
      != B->getOperand(i)->getType()->getTypeID()) return false;
  return true;
}

I'm not sure if it's too much.
Thanks!

Artur

P.S. Sorry for that [Junk...] in few mails. It's our "great" antispammer, I
will switch to gmail.
