Maybe the demos were not specifically built for 060 (afaik that would only be
possible with gcc). I guess they were just build for 020 or better (or maybe
040), then run on 060.
Compiling for 060 would avoid such instructions, and directly call library
functions if needed. That would still be slower than using 68882 fpu, but
faster than having to catch the exception first, then jumping to the FPSP
which has to analyze the instructions to know what to do.
