Nick Clark is working on ARM, but we are still missing at least the
following importantish JIT implementations:

* PPC - PowerPC (Motorola) and POWER (IBM) -- I know there's a "common"
instruction set that works both on the "consumer" PPCs and the HPC
(high performance computing) POWER chips.

* MIPS - I know a little bit more about these, but I *suspect there's
a simple common instruction set

* HPPA - I know very little about these, is there a common instruction set?

* IA64 - reports of the IA64 instruction set tell that it combines
the "elegance" of the IA32 CISCy instruction set with
the "elegance" of the HPPA RISCy instruction set... :-)

I intend to do nothing on these except raise gui^H^H^Hawareness :-)

I'm working on this.

Or give me an acount? ;)

For the HPPA and IA64 I think getting an account in the HP/CPQ Test
Drive machines should help:

For MIPS, I dunno whether SGI has something similar.

PlayStation is little endian mips, so it would be interesting if one core can
do both that and the big endian SGI.

There are some big endian ARM development boards out there, but I don't think
there are any consumer products running big endian, and I've not been "good"
in being endian neutral.
