[llvm-dev] Suggestions on debugging pre-merge test failure that looks irrelevant.
The first error you linked is for Bazel, which is not officially supported, but you have opted in to the pre-merge checks by joining the Bazel phab project. That particular message comes from the tests that detect when config files have changed. As you noted, this is due to an old baseline for your patch (that was fixed 11 days ago in https://github.com/llvm/llvm-project/commit/c6cfd385b1). I'd generally recommend rebasing to more recent commits before sending something for review/testing anyway. For the second failure, you can see more details about the error in the error logs.
