infrun.c: stop_stepping -> stop_waiting.
stop_stepping is called even when we weren't stepping. It's job really is: static void stop_waiting (struct execution_control_state *ecs) { ... /* Let callers know we don't want to wait for the inferior anymore. */ ecs->wait_some_more = 0; } So rename it for clarity. gdb/ 2014-05-29 Pedro Alves <palves@redhat.com> * infrun.c (stop_stepping): Rename to ... (stop_waiting): ... this. (proceed): Update comment. (process_event_stop_test, handle_inferior_event) (handle_signal_stop, handle_step_into_function) (handle_step_into_function_backward): Update.
