Yes, in the last stage, I hope to make only one 'jit-m68k.def' file
which can be used for both jit and jit3. In that stage, maybe we
will have symbolic link to 'jit3-m68k.def' from 'jit-m68k.def'.

The reason to make them unified is for easy maintenance. As jit
hackers may know, the difference between jit and jit3 is not big.
Mainly, the later treats internal used registers smarter (I don't
say, it makes entire process faster, sigh...)

Later, I will back port floating point emulation code to jit, which
is only in jit3 right now. This effort may benefit non-FPU 68K
CPU's mainly used for embedded application. The other important
target is the half-damaged LC series CPU. (These cpu have broken
emulation trap and for long time, there were no way to use them
with unix-like system. This situation was changed by NB2, because
they provide 'soft-float' port for LC.)

OK, my declaration of dream was finished. Going back to the real
world...

So after this debugging effort, I will go back to do the second step.

Did you send me mail in this period? I sometimes automatically
delete HTML mail without reading the contents ;-)
