-fsanitize=undefined complains about using operator~ on various enum types that are used with DEF_ENUM_FLAGS_TYPE. This patch fixes these problems by explicitly setting the base type for these enums to unsigned. It also adds a static assert to enum_flags to ensure that future enums used this way have an unsigned underlying type. gdb/ChangeLog 2018-10-03 Tom Tromey <tom@tromey.com> * common/enum-flags.h (enum_flags::operator~): Add static assert. * symfile-add-flags.h (enum symfile_add_flag): Use unsigned as base type. * objfile-flags.h (enum objfile_flag): Use unsigned as base type. * gdbtypes.h (enum type_instance_flag_value): Use unsigned as base type. * c-lang.h (enum c_string_type_values): Use unsigned as base type. * btrace.h (enum btrace_thread_flag): Use unsigned as base type.
