I'm really not sure I understand this strncmp (but also the ones for arm and
thumb), does that mean you want to accept also general-regs-only123 or
general-regs-onlycorgewaldo or thumb__ ? If you want to support e.g. only
optional whitespace after the string, each handled case should update the
pointer and then something after it should verify/diagnose.
Also, single stmt if bodies shouldn't be wrapped with {} and the arm case is
misindented.
Otherwise, I think the eh_personality.cc change is acceptable to me (but ask
Jonathan or other libstdc++ maintainers).
