    But it does through:


    static inline void *__memcpy3d(void *to, const void *from, size_t len)
    if (len < 512)
    return __memcpy(to, from, len);
    return _mmx_memcpy(to, from, len);

    #define memcpy(t, f, n) \
    (__builtin_constant_p((n)) \
    ? __constant_memcpy3d((t), (f), (n)) \
    : __memcpy3d((t), (f), (n)))

    I know, technically it is doable, but do you see a K7 box with an EFI
    firmware? I, at least, don't think so... :-)

    Now, if you think that those optimizations could be used on other boxes
    which could sport EFI, then that's a whole another question...
