Yes, that was part of my motivation.  But, (current) documentation on how
to write MLRISC backends is a little sparse, so I wanted to check how it
worked with a current system.

Well, as far as I can tell, ASDLgen hasn't been touched in 3 years or so,
so it might be a moot point.

I don't quite follow this.  What is the issue?
