> @fhahn Any news on this? I'd suggest reverting the change for now -- with the amount of commits in between it will be hard to determine whether the regression was fully addressed.

compile-time should be restored by limiting to loop-invariant source/sinks for now (234cc40adc610a55d1a5a2fe798a9dd07b993f0c). There's only a very small change with the original commit reverted on top of that one (0.01% change). WDYT?

 I also have a few patches to improve compile-time for the general version which I'll be working on as follow-ups
