    pub fn _mm256_mask_rcp_ph(src: __m256h, k: __mmask16, a: __m256h) -> __m256h

🔬This is a nightly-only experimental API. (`stdarch_x86_avx512_f16` #127213)
Available on (x86 or x86-64) and target feature `avx512fp16` and target feature `avx512vl` and x86 only.
Expand description

Compute the approximate reciprocal of packed 16-bit floating-point elements in `a` and stores the results in `dst` using writemask `k` (elements are copied from `src` when the corresponding mask bit is not set). The maximum relative error for this approximation is less than `1.5*2^-12`.
