But it's got variables, so you can pretend: "for the purposes of assignment
3, variables named `r0' through `r31' have access times 1/10 of that of any
other variable, and stack depth may not exceed 2 -- cope accordingly". You
could also define postfix macros to simulate whatever restricted forms you
wanted: "r0 x ld" instead of "ld r0, x". Neither of these is quite as
satisfactory as "the real thing", but they should suffice to expose the
students to realistic constraints.
