505 | somewhere within the call dummy. They may need to know whether the | |
506 | call dummy has actually completed. (For example, wait_for_inferior | |
507 | wants to know when it should truly stop because the call dummy has | |
508 | completed. If we're single-stepping because of slow watchpoints, | |
509 | then we may find ourselves stopped at the entry of the call dummy, | |
510 | and want to continue stepping until we reach the end.) | |

514 | therefore cannot use the CALL_DUMMY_BREAKPOINT_OFFSET mechanism. | |

517 | default implementation of CALL_DUMMY_HAS_COMPLETED is sufficient. | |
