I do have ideas but how it will play out is unknown. Also the current priority is to improve maintainability of the code with getting rid of the non-SLP data structure using paths in the vectorizer. Next would be to redo loop SLP discovery from scratch which would include possibly fixing this issue. > Thanks, > -Jiangning
