Summary: opCmp return value unclear

Hardware: All

When implementing an opCmp, I pretty much always need to look up how it is
defined and the specification constantly disappoints but not saying a word of
what the function should actually return for which case.
you can kind of extract that info from the re-write rules, but why make it so
difficult and not just say something like
RETURN A B
-1 2 1
0 2 2
+1 1 2
(or whatever the correct numbers are)
