> There may be another road if you think that would be better: we could keep the current loop rotation as is, and add a new loop rotation pass in a different file, and then deprecate the existing pass once everybody is convinced that the new code is better. Would that work for you?


Hmm... something like that would work, if you would prefer it.  Maybe put the new implementation behind a flag, rather than actually making it a separate pass, to reduce the churn outside of loop-rotation.
