For the sake of discussion, is this something akin to arm vs thumb?
Yes. Here's my analysis of the situtation:
* fields, operands, instructions are deliniated by the isa
in my port (just like arm,thumb).
* a pair of the opcodes files need to be completely generated down
this axis, modulo things in common -- but what are they?
What's a good way to proceed?
