I wouldn't worry about that, I don't think it's used nearly as frequently. The v1f64 issue comes up because that's how arm_neon.h represents some vectors.

That's right. Full support for _Float16 is part of v8.2 I believe, but tracked as a separate feature in LLVM: "fullfp16" if you're doing -mattr.
