Hi @trentxintong , I am just starting to review this diff and will get back to you with more meaningful comments soon. While I'm doing that could you tell me if this work is from a bug you discovered or for a new feature you'd like to see implemented.  Looking at your .ll changes below makes me believe this is a new feature, but I'd like to be sure to know.
