>Can we benchmark the current arrow::util::Float16 and the hardware float16? **Several notes:** 1. I do not have any hardware that supports the `f16p` instruction, so I cannot conduct benchmarks. 2. I checked the assembly code generated [here](https://godbolt.org/z/nznx9GbKj)and [here](https://godbolt.org/z/dr7fx83Ps), and I found hardware instructions for FP16 operations. 3. I plan to enable arithmetic operations for `+`, `-`, `*`, and `/`. 4. I think that even if we conduct a benchmark and `arrow::util::Float16` performs significantly better than GCC and Clang, it is still better to rely on compiler support and wait for further improvements from the compilers. @kou, what is your opinion? -- This is an automated message from the Apache Git Service.
