yes please.  please raise a bugreport about it, assign it to yourself,
and make certain to use the ReservationStations base class and test
infrastructure (runfp) exactly as i described in here:

https://bugs.libre-soc.org/show_bug.cgi?id=208#c55

*all* ALUs need to have that common interface (multiple
inputs-outputs).  if you can, use runfp - if there's any assumptions
about the format being FP numbers, add an extra parameter which does
debug printing as hexadecimal.  i *think* it should do that anyway
because i used the same runfp test code for FP-to-INT and INT-to-FP
