I see. I would like to ask a stupid question: where can I find PocketLinux
Kaffe. The URL http://www.pocketlinux.com cannot be reached.

Even if the GC interface doesn't diverge much between the two, I wonder if
the GC for PocketLinux is suitable for Kaffe. PocketLinux is developed for
hand-held or mobile devices. GC for these resource constraint environments
cannot be very complicated and has many restrictions. So I would like to
take a look on PocketLinux's source code, see how it can have Boehm's GC
merged. If possible, I would like to merge PocketLinux's GC into Kaffe (if
that's not too tedious), see if there is any performance improvement.
Final question: I would like to know if there is any write barrier
implemented in Kaffe-1.0.7 currently? It seems that it is somehow
implemented in Kaffe (GC_WRITE?), but I cannot find its implementation.
Would you mind tell me where does its source code locate? I think a write
barrier is important for an incremental/asynchronous GC.
Actually, I use Kaffe for my research purpose. Currently I try to study and
understand the entire memory management system of Kaffe. I would be very
grateful if you can answer my questions. Thanks!

Zoe
