  11. I immediately thought, shouldn't matter since executor compiles the Mac
  12. code itself, and that's the code that takes most of the time.  But is that
  13. true?  How much time does executor spend in its various modules (screen
  14. update, instruction emulation, routine compilation, routine execution)?
  15.  
  16. Btw, the assembler output from gcc (and presumably djgcc) looks quite a
  17. bit more pentium-friendly if -fforce-mem is specified.  OTOH there seems
  18. to be a bug in -fforce-mem in the latest gcc snapshot, so it might not
  19. work.
