If one is watching new_objfile events in python, it helps to know when the list of objfiles is cleared. This patch adds a new clear_objfiles event to support this. This patch is all just cut-n-paste-n-tweak derived from the new_objfiles event. gdb/ChangeLog: * NEWS: Mention new event gdb.clear_objfiles. * python/py-event.h (emit_clear_objfiles_event): Clear * python/py-events.h (events_object): New member clear_objfiles. * python/py-evts.c (gdbpy_initialize_py_events): Add clear_objfiles event. * python/py-inferior.c (python_new_objfile): If objfile is NULL, emit clear_objfiles event. * python/py-newobjfileevent.c (create_clear_objfiles_event_object): New function. (emit_clear_objfiles_event): New function. (clear_objfiles): New event. * python/python-internal.h (gdbpy_initialize_clear_objfiles_event): Declare. * python/python.c (_initialize_python): Call gdbpy_initialize_clear_objfiles_event. gdb/doc/ChangeLog: * python.texi (Events In Python): Document clear_objfiles event. gdb/testsuite/ChangeLog: * gdb.python/py-events.exp: Update expected output for clear_objfiles event. * gdb.python/py-events.py: Add clear_objfiles event.
