Normally people "ping" a PR if it hasn't had any review after a week. You should also add some reviewers, by (if you have commit access) modifying the reviewers list, or (if you don't) pinging them here. I'd typically have reviewed this myself by now, but I'm on a reviewing pause, due to non-LLVM workloads being high at the moment.

I suggest you reopen and update (if needed). We aim for compatibility with the GNU tools wherever possible, so I'd guess this PR has merit (but I can't be sure without digging deeper, which I won't have time for for a couple more weeks probably).
