> If these failures are unrelated to your changes (for example tests are broken or flaky at HEAD), please open an issue at https://github.com/llvm/llvm-project/issues and add the `infrastructure` label.
The latest check failure appears to be due to the new test introduced by 564d69a8dec3183ebd78a779efdd8903bbe89f68 on main, rather than this patch itself.
I rebased this PR locally onto the latest main and the relevant test passes there. I can push the rebase to refresh the CI results.
