[PATCH] D127884: [Draft][LangRef] Document `elementtype` attribute requirement on atomic memory intrinsics.

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

I don't understand the motivation here.  Clearly, such an environment could tag the operations this way, and probably should.  However, why does that need to be in the LangRef as a requirement?  Is the idea to disallow some particular transform in tree that can't meet this?
