At that point, there were two sets of enumerators in a single enum -- which is why these were eventually split. This confusion leaked out to the Python API as well, as noted in PR python/21765. This patch deprecates the constants that aren't useful to the Python API. They are left in place for now, but removed from the documentation. Also, their values are changed so that, if used, they might work. Finally, missing domains and location constants are added. gdb/ChangeLog 2018-10-06 Tom Tromey PR python/21765: * python/py-symbol.c (gdbpy_initialize_symbols): Redefine SYMBOL_VARIABLES_DOMAIN, SYMBOL_FUNCTIONS_DOMAIN, SYMBOL_TYPES_DOMAIN.
