The predicates are added and exists in the order given by GraphKit::add_predicate.

PhaseIdealLoop::find_predicate searches for them in a different order. This doesn't really matter, but it would be nice if this code were consistent with other code looking for these predicates.

Node* PhaseIdealLoop::find_predicate(Node* entry) {
  Node* predicate = NULL;
  predicate = find_predicate_insertion_point(entry, Deoptimization::Reason_loop_limit_check);
  if (predicate != NULL) { // right pattern that can be used by loop predication
    return entry;
  }
  if (UseLoopPredicate) {
    predicate = find_predicate_insertion_point(entry, Deoptimization::Reason_predicate);
    if (predicate != NULL) { // right pattern that can be used by loop predication
      return entry;
    }
  }
  if (UseProfiledLoopPredicate) {
    predicate = find_predicate_insertion_point(entry, Deoptimization::Reason_profile_predicate);
    if (predicate != NULL) { // right pattern that can be used by loop predication
      return entry;
    }
  }
  return NULL;
}
