Function _mm512_maskz_rsqrt_ph

pub unsafe fn _mm512_maskz_rsqrt_ph(k: __mmask32, a: __m512h) -> __m512h

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on (x86 or x86-64) and target feature avx512fp16 and x86-64 only.

Compute the approximate reciprocal square root of packed half-precision (16-bit) floating-point elements in a, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set). The maximum relative error for this approximation is less than 1.5*2^-12.
