What about (complex) bonus feature: enable all FPU arithmetic exceptions
and capture and log them too. If instruction causes arithmetic
exception, log the exception number, disable exceptions, restore stack
and execute tested instruction again. Then re-enable exceptions and
execute next instruction and so on..

This would be big help for implementing arithmetic exception emulation.
