They are both implementing the same C++ feature, with the same desired semantics of zeroing out any bits in the object representation that aren't in the value representation. If they differ, one or the other would have a bug. > Is there a specification for __builtin_zero_non_value_bits available > somewhere? I don't know if there is a formal spec for it beyond the actual C++ standard.
