  22         (linux_resume_one_lwp): Store the thread's PC.  Adjust to clear
  23         stop_reason.
  24         (check_stopped_by_watchpoint): New function.
  25         (save_sigtrap): Reimplement.
  26         (linux_nat_stopped_by_watchpoint): Adjust.
  27         (linux_nat_lp_status_is_event): Delete.
  28         (stop_wait_callback): Only call save_sigtrap after storing the
  29         pending status.
  30         (status_callback): If the thread had been stopped for a breakpoint
  31         that has since been removed, discard the event and resume the LWP.
  32         (count_events_callback, select_event_lwp_callback): Use
  33         lwp_status_pending_p instead of linux_nat_lp_status_is_event.
  34         (cancel_breakpoint): Rename to ...
  35         (check_stopped_by_breakpoint): ... this.  Record whether the LWP
  36         stopped for a software breakpoint or hardware breakpoint.

  43         (linux_nat_wait_1): Remove 'retry' label.  Remove references to
  44         new_pending.  Don't handle leaving events the caller is not
  45         interested in pending here, nor handle signal short-circuiting
  46         here.  Also give equal priority to all LWPs that have had events
  47         in non-stop mode.  If reporting a software breakpoint event,
  48         unadjust the LWP's PC.
  49         * linux-nat.h (enum lwp_stop_reason): New.
  50         (struct lwp_info) <stop_pc>: New field.

  80         factored out from ...
