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

505 | require more than a single breakpoint in their call dummies, and | |
506 | therefore cannot use the CALL_DUMMY_BREAKPOINT_OFFSET mechanism. | |

509 | default implementation of CALL_DUMMY_HAS_COMPLETED is sufficient. | |

511 | the presense of multiple breakpoints in its call dummy. | |
