Well, I've got JIT3 working to some extent on Amiga now.
It runs Hello World, but doesn't compile yet. However, I'm painting myself
into a corner here with the changes I'm making to the config files.
Specifically, the files:
I have had to make considerable changes to all of these files (things like
register allocations are very different between Amiga and Linux), and in
order to maintain the cross-platform portability, we can do one of several
things (there may be a better way, please suggest):
(1) put conditional compilation in the files mentioned above;
(2) redefine some register and other names as macros in a
(3) split the files into independent config/m68k/$$OS versions and edit
kaffe:configure to make kaffevm/kaffe.def point to config/m68k/$$OS
I prefer (3) because we can then have independent files to work on, without
the danger of breaking each other's port. But it may be better some other
What do you think?
