7d221d749c
The first patch in this series went through several iterations as I'd forgotten how many places had to be touched to add a new event and a new event type. This patch simplifies the process using two new ".def" files. Now, a new event type can be added by adding a line to "py-event-types.def", and a new event registry can be added by adding a line to "py-all-events.def". ChangeLog 2017-09-11 Tom Tromey <tom@tromey.com> * python/python.c (do_start_initialization): Use py-event-types.def to initialize types. Define all object type structures. * python/python-internal.h: Don't declare event initialization functions. * python/py-threadevent.c (thread_event_object_type): Don't define. * python/py-stopevent.c (stop_event_object_type): Don't define. * python/py-signalevent.c (signal_event_object_type): Don't declare or define. * python/py-newobjfileevent.c (new_objfile_event_object_type) (clear_objfiles_event_object_type): Don't declare or define. * python/py-infevents.c (inferior_call_pre_event_object_type) (inferior_call_post_event_object_type) (register_changed_event_object_type) (memory_changed_event_object_type): Don't declare or define. * python/py-inferior.c (new_thread_event_object_type) (new_inferior_event_object_type) (inferior_deleted_event_object_type): Don't declare or define. * python/py-exitedevent.c (exited_event_object_type): Don't declare or define. * python/py-evts.c (gdbpy_initialize_py_events): Use py-all-events.def. * python/py-events.h (thread_event_object_type): Don't declare. (events_object): Use py-all-events.def. * python/py-event.h (GDBPY_NEW_EVENT_TYPE): Remove. Use py-event-types.def. * python/py-event-types.def: New file. * python/py-continueevent.c (create_continue_event_object): Don't declare or define. * python/py-bpevent.c (breakpoint_event_object_type): Don't declare or define. * python/py-all-events.def: New file.
