6005 2014-01-08  Pedro Alves  <palves@redhat.com>
6006
6007         * server.c (handle_status): Don't discard previous queued stop
6008         replies or thread's pending status here.
6009         (main) <disconnection>: Do it here instead.
6010

6012
6013         * gdbthread.h (struct thread_info) <status_pending_p>: New field.
6014         * server.c (visit_actioned_threads, handle_pending_status): New
6015         function.
6016         (handle_v_cont): Factor out parts to ...
6017         (resume): ... this new function.  If in all-stop, and a thread
6018         being resumed has a pending status, report it without actually
6019         resuming.
6020         (myresume): Adjust to use the new 'resume' function.
6021         (clear_pending_status_callback, set_pending_status_callback)
6022         (find_status_pending_thread_callback): New functions.
6023         (handle_status): Handle the case of multiple threads having
6024         interesting statuses to report.  Report threads' real last signal
6025         instead of always reporting GDB_SIGNAL_TRAP.  Look for a thread
6026         with an interesting thread to report the status for, instead of
6027         always reporting the status of the first thread.

6052         (win32_wait): Add declaration.
6053         (do_initial_child_stuff): Flush all initial pending debug events
6054         up to the initial breakpoint.
6055         (win32_wait): If CACHED_STATUS was set, return that instead
6056         of doing a real wait.  Remove the code resuming the execution
6057         of the inferior after receiving a TARGET_WAITKIND_LOADED event
6058         during the initial phase.  Also remove the code changing
6059         OURSTATUS->KIND from TARGET_WAITKIND_LOADED to
6060         TARGET_WAITKIND_STOPPED.
