This makes me uneasy, do you mean you want to:

i) make a 'loop' target, if so why ?

ii) or that you want to rewrite loop so that it sits on top of dm -
ie. you create a set of linear mappings that correspond to the
file ? This would only be sensible if there is significant
simplification/reduction of the loop code, and probably would
never work because of tail packing.

I'm not keen on either of these ideas.
