Yes, sorry. I ran out of time. Learning and hacking powerpc assembly and
figuring out calling conventions is fun but very time consuming.

I don't have a powerpc build around at the moment. But also on x86 you
get things like:
sablevm: INTERNAL ERROR (source file "native_interface.c", line 24046):
todo
But I believe Etienne is working on those.

I believe there are some places that need investigating (like the one
mentioned in my patch). It seems to be mainly passing arguments and
getting results from calling native code through JNI that has some
problems. Programs that don't use classes with native code seem to work
OK.

Please let me know if you are going to use it. I can give pointers to
results with Kissme, kaffe or gcj so you know what to expect (there are
a couple of tests in Mauve that sadly fail on almost every VM and that I
expect to be wrong in the first place). But there are a couple of
