@HsiangKai could you please check what you intended those -NOT lines to originally check, and confirm if those changes are OK?

https://llvm.org/docs/CommandGuide/FileCheck.html#the-check-not-directive (a) Two identical CHECK-NOT directives between two positive matches are the same as one. (b) {{]}} is the same as ].
So I believe the changes are OK.
