Most of the conditional assembly has been deleted, leaving only the CF-specific code. In a number of cases, single 68k instructions have to be expanded for the CF - and the expanded sequences will be slower on the 68k. (And if you're really after quick-and-dirty FP arithmetic, IEEE isn't the way to go. It is comparatively slow (though far more robust). You might like to try and find a copy of Motorola's FFP).
