@yebinchon @nico Thanks for the quick fix and mentions! The failures caused by semantic conflict between this PR and https://github.com/llvm/llvm-project/pull/219952, the fix looks good to me. Somehow I forgot to rebase this PR after https://github.com/llvm/llvm-project/pull/219952 merged, I apologize for the problems this has caused.
