My English is not very good.I'm not sure I understand what you mean by the word “hold.”What does “good question” mean here? I've had time to think about it.Make my point. I think it's great when this Pass is introduced to handle situations where the SSA value has a range.
My understanding is that 
* -affine-loop-normalize is blocking content in this PR.
* This pass was inspired from SCF.
Thank you.
