* infrun.c (resume): In non-stop mode, always resume just one thread. (proceed): Don't call prepare_to_proceed in non-stop mode. (fetch_inferior_event): In non-stop mode, switch context before handling the event. (error_is_running, ensure_not_running): New. (handle_inferior_event): In non-stop mode: Mark only the event thread as stopped. Require that the target module manages adding threads to the thread list. Assert that there isn't a deferred_step_ptid set. Don't switch to infwait_thread_hop_state. (normal_stop): Only mark not-running if inferior hasn't exited. In non-stop mode, only mark the event thread. * thread.c:Include "cli/cli-decode.h". (print_thread_info): Don't read from a running thread. Output "(running)" if thread is running. (switch_to_thread): Don't read stop_pc if thread is executing. (do_restore_current_thread_cleanup): Don't write to a running thread. (thread_apply_all_command): Don't read from a running thread. In non-stop mode, do a full context-switch instead of just switching threads. (thread_apply_command): In non-stop mode, do a full context-switch instead of just switching threads. (do_captured_thread_select): Likewise. Inform user if selected thread is running. (_initialize_thread): Mark "info threads" and "thread" and async_ok. * inf-loop.c (inferior_event_handler): In non-stop mode, don't unregister the target from the event loop. * infcmd.c (continue_command, step_1, jump_command) (signal_command): Ensure the selected thread isn't running.
