…d neon_vaddvq_f64 (#1238) [Neon intrinsic definition](https://developer.arm.com/architectures/instruction-sets/intrinsics/vaddv_f32). They are vector across operation which LLVM doesn't currently have a generic intrinsic about it. As a side note for brainstorm, it might be worth in the future for CIR to introduce Vector Across type operations even though LLVM dialect doesn't have it yet. This would help to expose opt opportunities. E.g. a very trivial constant fold can happen if we are adding across a constant vector.

Neon intrinsic definition. They are vector across operation which LLVM doesn't currently have a generic intrinsic about it. As a side note for brainstorm, it might be worth in the future for CIR to introduce Vector Across type operations even though LLVM dialect doesn't have it yet. This would help to expose opt opportunities.
