--- Comment #3 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
ha, hilarious.

took a while to notice: M-Form is this:

    rlwnm RA,RS,RB,MB,ME (Rc=0)

where XO-Form is this:

    divdeu RT,RA,RB

however, underneath, the 2nd argument is *consistently a constant*.  this needs
to be swapped in the CSV file.  see issue #360
