[B2-devel] 68k->PPC JIT

[Jaime C. <jca...@gm...>]

This is probably interesting for Gwenole or maybe other experienced
coder... Bernd Meyer (Umisef), author of UAE-JIT and Amithlon has told
in public forums that he has almost finished a 68k->PPC JIT for UAE
that he would like to release if someone would like to fix a pair of
FPU bugs that are still there. He doesn't have time or the will to
finish it and he wouldn't like to release it but that no one updates
or maintains it.

Is there someone qualified and with the will for the job? This is
interesting for all PPC owners...

If someone is interested in the "job" and can't contact Bernd Meyer
drop me an email and I'll put you in touch with him.

Is this a recent declaration? It has been a long time since I read =20
him working on a PPC backend for the JIT and he designed the code =20
with that target in mind. This is mostly useful nowadays now that we =20
have a testsuite, though not for FPU instructions yet. This would be =20
a good start though, to check the individual translated instructions =20
semantics.

I plan to change a few things in the JIT code and it would be nice =20
indeed to have a look at his PPC backend.

Bye,
Gwenol=E9.=

Yes, this is quite recent. He didn't want to release the 68k->PPC JIT
before AmigaOS4 was released but now he's willing to release it.

I've written Mr Meyer and I hope he replies soon.
