Well, this is a little bit more complicated.
This was working, but not doing what you would expect :).
Basically, this was running codegenprepare without TargetLowering information, thus it was not doing much.

Anyway, I will try to come up with a simple test. I have a big test for what I am working on, but it does not hurt to have something simpler landing before that.

Thanks,
Quentin
