--- Comment #41 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
michael i've just made a half-broken effort to add CR to the simulator.
to get it to work, i added CR (and other special regs) to the list of
parameters that will be passed in and also returned.  whether these
should be added to namespace is debatable (probably not), kept separate

i also created something called FieldSelectableInt which can "refer"
to a subset (of SelectableInt) just like in the Power Decoder.

the idea being to allow CR0 to be "accessed" (arithmetically) including
assignments, and have that actually go *directly* into CR.
