5753 2014-01-08  Pedro Alves  <palves@redhat.com>
5754
5755         * server.c (handle_status): Don't discard previous queued stop
5756         replies or thread's pending status here.
5757         (main) <disconnection>: Do it here instead.
5758

5760
5761         * gdbthread.h (struct thread_info) <status_pending_p>: New field.
5762         * server.c (visit_actioned_threads, handle_pending_status): New
5763         function.
5764         (handle_v_cont): Factor out parts to ...
5765         (resume): ... this new function.  If in all-stop, and a thread
5766         being resumed has a pending status, report it without actually
5767         resuming.
5768         (myresume): Adjust to use the new 'resume' function.
5769         (clear_pending_status_callback, set_pending_status_callback)
5770         (find_status_pending_thread_callback): New functions.
5771         (handle_status): Handle the case of multiple threads having
5772         interesting statuses to report.  Report threads' real last signal
5773         instead of always reporting GDB_SIGNAL_TRAP.  Look for a thread
5774         with an interesting thread to report the status for, instead of
5775         always reporting the status of the first thread.

5800         (win32_wait): Add declaration.
5801         (do_initial_child_stuff): Flush all initial pending debug events
5802         up to the initial breakpoint.
5803         (win32_wait): If CACHED_STATUS was set, return that instead
5804         of doing a real wait.  Remove the code resuming the execution
5805         of the inferior after receiving a TARGET_WAITKIND_LOADED event
5806         during the initial phase.  Also remove the code changing
5807         OURSTATUS->KIND from TARGET_WAITKIND_LOADED to
5808         TARGET_WAITKIND_STOPPED.
