Thanks @suez1224 @fhueske for the comments. I will change them accordingly.
Yes I copied a lot of test cases from @haohui's PR for my own testing. I
can definitely put it on top given the runtime support is already merged in
#5555. Procedure-wise question: should I rebase his commit then add my change
on top, then attached to this PR? I am not sure if there's a clever way to both
preserve the discussion in this thread and rebase on top of his change.
