Hi Martin!

That would be really great! I hope it won't take too long before
gcc 3.4 (-0preX) hits unstable (probably as we release sarge, no? ;-)

Looking forward to make SableVM work on mips/mipsel

PS: Cc:ing SableVM-devel ML w/ these news. I hope you don't mind.

PPS: In fact, if we have everything installed BUT the libffi, then
it's quite easy to just fetch gcc-3.4 source and compile libffi
only. See http://devel.sablevm.org/wiki/LibFFI for instructions.

If you were able to fill in needed info in system.c and system.h files
- then I think you can make SableVM work on mips "just like that".
Ignore cache flush function, you only need atomic compare&swap (or
make a plai-C stuf at first), and basic informations about word/page
size of your arch.

Hm... I've just written quick porting guide at
