We don't accept these kinds of comments in the source as 1) the copyright part is not necessary per https://llvm.org/docs/DeveloperPolicy.html#copyright-license-patents, 2) it doesn't scale well because the files will quickly become littered with such notices, 3) I think anything like this would require LLVM Foundation approval.

Is it a requirement for your contract to have these kinds of comments in the source code? Or would putting some of it (not the copyright paragraph) into the commit message when landing the changes suffice?
