I understand that.  But I'm not too interested in code generation (I can
write this myself or adapt other code). What I need is a processor
simulation to generate code for, preferrably a clone of an x86, one that
executes its own instruction set.  Then I can test the JIT in Smalltalk.

I believe Peter Deutsch write a 68000 simulator when he implemented PS, the
first Smalltalk-80 JIT, but I could be wrong and perhaps he only implemented
an assembler for the 68000.
