I initiated the merge, but it seems that github mangles the email metadata:

(Note that I obscured your email address in this screenshot, but it can be found within the commits that you published.)

- If you want to use your "real" email address as the Author of this commit, then you probably need to change your github account settings. (I don't know the exact details but IIRC you can toggle whether it will use your email address in your commits.)
- If you don't want to embed that email address into the LLVM git history, then I can merge the commit without the `Signed-off-by` and `Co-authored-by` lines that mention it. The address will remain on the internet (in this pull request), but it won't be part of the LLVM main branch.
