Trivia time. The reason I did that many years ago when first ported
the 8xx
was I had only 6xx tools and libraries available. Even though you don't
have any floating point in your program, things like initialization,
set/longjmp,
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
development
kit specific to the 8xx that has applications and libraries already
properly
compiled. Without math emulation enabled, you still get those few
trivial traps emulated.
