Thanks @david-arm for volunteering, and for your sustained work in the Loop vectorizer. As Kiran suggested it is noteworthy.
@fhahn Adding him as a maintainer will only strengthen the project. Noting that you have already indicated “more than happy to have more maintainers,” it seems we have the needed support. Could we reopen and merge this as per LLVM policy.
