Yes that's what it computes.. and no the function won't ever get used on
x86_64, but I ran it through the compiler anyway :-)
Thing is we need u128 to work on all archs linux supports on all gcc version we
support, so we can't use __int128. Anyway, if you're interested in what we're
doing and want to see the current patches click:
