524 | somewhere within the call dummy. They may need to know whether the | |
525 | call dummy has actually completed. (For example, wait_for_inferior | |
526 | wants to know when it should truly stop because the call dummy has | |
527 | completed. If we're single-stepping because of slow watchpoints, | |
528 | then we may find ourselves stopped at the entry of the call dummy, | |
