I'd expect glibc to use such a feature together with the __mpn_* bits of GMP that are already used for some purposes in printf / strtod. That means using LE together with the mp_libm_t type used in glibc, which need not match the _BitInt endianness or libm size (thus, a feature restricted to following the _BitInt ABI more closely would be less convenient to use in glibc). -- Joseph S.
