The backend is pretty mature, the register allocator is already
quite competitive. You can see some code it generates, here:

I'm currently fixing side-exit handling. As it turns out, this is
the most tricky part of a trace compiler. And of course there are
still lots of small things everywhere that are missing or need to
be rewritten.

No major blockers, just a lot of detail work before I can think
about releasing it.
