[PATCH] D120395: [X86] Prohibit arithmetic operations on type `__bfloat16`

[Steve Canon via Phabricator via cfe-commits]

scanon added a comment.

There's a lot of churn around proposed "solutions" on this and related PR, but not a very clear analysis of what the problem we're trying to solve is.

Concretely, what are the semantics that we want for the BF16 types and intrinsics? Unlike the other floating-point types, there's no standard to guide this, so it's even more important to clearly specify how these types are to be used, instead of having an ad-hoc semantics of whatever someone happens to implement.
