Hm... I did code generators for SPARC and MIPS roughly 10 years ago.
Later on I added a code generator for Alpha which was adapted from
the MIPS code, but which became much more exciting ultimately because
I added floating point, polar coordinates, trig functions, etc.
I did make a quick Java JIT for x86 in 1995 which I bolted into the
then brand-new Sun interpreted runtime. I imagine it would be possible
to adapt those macros to make an x86 pico (for what else do people use
these days but x86s??), but I haven't spent time on pico in years
and years.
I hardly participate in 9fans and I don't know where to post the code
these days. If someone would like a bundle of my pico directory with
the three above-mentioned code generators (SPARC/MIPS/Alpha), let me know.
Byron.
