The link commit in description gives a 404 because it sends me to https://github.com/llvm/llvm-project/pull/url, but if I copy the text, then it brings me to the correct commit.

The compiler will never emit a Zcmt instruction and as far as I know lld support isn't done. So I'm not sure what we want "Supported" to mean here.
