68020-68040 bin (in)compatibility...?

Hi everyone,

can anyone tell me to which extent are there incompatibilities
of code compiled for 68020+68881 to be run on a 68040?
I heard there were 7 instructions for the 68020+68881
that are not compatible on the 68040, and 5 of them
were related to FPU operations. Is it really like this?

The question is, how can I assure that code compiled
for a 68020+68881 platform will run without any problems
on a 68040 platform? Must I avoid the use of trigonometric
functions only, or is it more than that?

Thanks in advance!
Best regards.
