--- Comment #7 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
The ELFv2 ABI Appendix B calls for a bcd data type defined as:
typedef bcd vector unsigned char;
and then defines a bunch of potential functions that can be built around it.
The BCD functions (such as __builtin_bcdadd), earlier in the appendix, are
defined in terms of vector unsigned char.
GCC has just never gotten around to implementing these, due to a combination of
user disinterest and resource constraints. We'll have to step up to these,
hopefully in GCC 11 (though our plate is really full there already).
