507 | /* It's often not enough for our clients to know whether the PC is merely | |
508 | somewhere within the call dummy. They may need to know whether the | |
509 | call dummy has actually completed. (For example, wait_for_inferior | |
510 | wants to know when it should truly stop because the call dummy has | |
511 | completed. If we're single-stepping because of slow watchpoints, | |
512 | then we may find ourselves stopped at the entry of the call dummy, | |
513 | and want to continue stepping until we reach the end.) | |
