   2
   3         * gdbthread.h (struct thread_info) <status_pending_p>: New field.
   4         * server.c (visit_actioned_threads, handle_pending_status): New
   5         function.
   6         (handle_v_cont): Factor out parts to ...
   7         (resume): ... this new function.  If in all-stop, and a thread
   8         being resumed has a pending status, report it without actually
   9         resuming.
  10         (myresume): Adjust to use the new 'resume' function.
  11         (clear_pending_status_callback, set_pending_status_callback)
  12         (find_status_pending_thread_callback): New functions.
  13         (handle_status): Handle the case of multiple threads having
  14         interesting statuses to report.  Report threads' real last signal
  15         instead of always reporting GDB_SIGNAL_TRAP.  Look for a thread
  16         with an interesting thread to report the status for, instead of
  17         always reporting the status of the first thread.

  42         (win32_wait): Add declaration.
  43         (do_initial_child_stuff): Flush all initial pending debug events
  44         up to the initial breakpoint.
  45         (win32_wait): If CACHED_STATUS was set, return that instead
  46         of doing a real wait.  Remove the code resuming the execution
  47         of the inferior after receiving a TARGET_WAITKIND_LOADED event
  48         during the initial phase.  Also remove the code changing
  49         OURSTATUS->KIND from TARGET_WAITKIND_LOADED to
  50         TARGET_WAITKIND_STOPPED.
