A new kaffe upstream snapshot with debian support for mips and
mipsel has been uploaded. It seems it couldn't be built on mipsel :'(


I contact upstream.
Thanks for the quick notice. I'm cross-ing to all debian arches atm to
fix build problems I failed to notice ;( Fixes for ia64 and mipsel are
in CVs already, a fix for arm is in the works.
I heard the mips/mipsel fix means to switch to a slow generic cmpxchg,
have I understood this correctly?

Yes. We'd need someone to look over the mips(el) cmpxchg to make an
adaptation for the new glibc-based locking primitivs. I've CC:ed
Guilhem, who can supply the details. I think he needs a specific variant
of cmpxchg which returns the old value.

I'm looking forward to patches, in particular to get the jit flying
again on mips ;(

The new package should be uploaded today, thanks to Arnaud.

I need an inlined function which does this, according to katomic.h:

/* Atomically store NEWVAL in *MEM if *MEM is equal to OLDVAL.
  Return the old *MEM value anyway.  */

where MEM, NEWVAL and OLDVAL are parameters of that function.

If someone feels to do it (but it is not necessary as there are default routines in katomic.h), he/she may also implement atomic_increment, atomic_decrement using inline asm.
