Jon Olson added write barrier support to gcc in the back end. If we
used this approach we could add it to both g++ and gcj. There might
be some odd special cases, but it is doable.
This sounds like something that would get put on a wish list and never
done, unless some volunteer were really motivated. My question to you
is whether it would be worthwhile in the context of your GC.
