Basically none.
The compiler is independent of kaffe. We're writing a new class
library and a new runtime.

Some things can't be changed without understanding all 3 parts
(compiler, debugger, runtime). For instance, object and class layout
information is shared between all three.
I doubt this will ever change. But then, I'd expect changes to these
things to be relatively infrequent.
The bulk of the class libraries are written in Java. System-dependent
things (threads, file I/O) are fairly easy to port.
GC is going to be another tricky area. We haven't really started work
on the interesting stuff there yet. For now we're just using the
Boehm conservative GC.
There is no bytecode interpreter yet.
