This has always been the plan.  One of Alex's GC papers talks about
doing this.

I'm curious about your port.  What makes it "embedded"?  In what way
is the current compiler not suitable?  What runtime are you using?

Where are you putting the write barriers?  In the front end?  In the
back end?  (We rely heavily on our Java/C++ integration, so I think
they might be better put further back.)

Do you allow multiple write barrier implementations per target?  If
so, how?

Can you sign papers for the FSF and contribute your code?  Signing
papers is a prerequisite for any major contribution to end up in the
core.  I believe for the compiler you can use the standard FSF
paperwork (for the runtime, I don't know).
