Another example is string comparison.  I use a string compare function
that returns the index of the first different character.  I also
need the gt/lt/eq result.  Fortunately, in this case it is easily 
computed by recomparing the chars at the index.  This is another case
of a double valued hardware primitive.  (Available on all three
of the architectures we use: Series/1, 80286, 68020.)
