Edouard told me he thinks the SP_OFFSET is okay.
Another chance maybe that you'll need FP_OFFSET as well.
The third, least attractive possibility is that the setjmp/longjmp
based approach won't work at all on alpha/OSF, which means that
you'll need a custom thread switching routine, similar to the one
Btw, Edouard did some work on trying to get the jit up and running
again, but there's still some problems. If you're interested in
cooperating on that, you may want to contact him.

To support DCPI and DCPI-like systems, I've started including the
kaffe.management.JIT class; the implementation of some native methods
is missing at this point though. k.m.JIT allows you to dump information
about where translated methods are located on the heap; this is needed
