Thanks for commenting!

> Sounds reasonable to go for (2) at this time?

Yep, completely agreed. This was actually my initial approach, but now I can't remember why I gave up on it, possibly because loop-simplify wasn't doing what I wanted and/or I got the impression it could just be a small fix in the LV. But that's not an excuse, so will indeed go for the loop canonical form approach.

I will keep this ticket open and rebrand/reuse it when I have results with loop-simplify/indvars.
