[Mlir-commits] [mlir] [mlir][generate-test-checks] Do not emit the autogenerated note if it exists (PR #143750)

[Michael Maitland]

https://github.com/michaelmaitland created https://github.com/llvm/llvm-project/pull/143750

Prior to this PR, the script removed the already existing autogenerated note if we came across a line that was equal to the note. But the default note is multiple lines, so there would never be a match. Instead, check to see if the current line is a substring of the autogenerated note.

Subject: [PATCH] [mlir][generate-test-checks] Do not emit the autogenerated
 note if it exists

Prior to this PR, the script removed the already existing autogenerated
note if we came across a line that was equal to the note. But the
default note is multiple lines, so there would never be a match.
Instead, check to see if the current line is a substring of the
autogenerated note.
