Apologies, but it was brought to my attention recently that the commit that was tagged as 22.1.2 for the llvm-test-suite was incorrect. As a consequence of that, the sources currently listed at LLVM GitHub, are currently incorrect. I have corrected the tag to point to the correct commit and the sources are now available at the llvm-test-suite release LLVM Test Suite GitHub. We are currently working to update the sources on the official LLVM release page and hope to have it done soon. I apologize for any inconvenience this may have caused. We will post a note here when the correct sources have been uploaded.

Thanks to @amy-kwan for bringing this to my attention!
