Trivia time. The reason I did that many years ago when first ported
was I had only 6xx tools and libraries available. Even though you don't
have any floating point in your program, things like initialization,
signals and so on would assume an FPU was available. So, I just
trapped those few FP load/store instructions. Later on, I did the whole
math emulation thing. Of course, today the best solution is a
kit specific to the 8xx that has applications and libraries already
compiled. Without math emulation enabled, you still get those few
trivial traps emulated.
