Function core::arch::x86::_mm_mask_rcp14_pd

pub unsafe fn _mm_mask_rcp14_pd(
    src: __m128d, 
    k: __mmask8, 
    a: __m128d
) -> __m128d

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on x86 and target feature avx512f,avx512vl only.

Compute the approximate reciprocal of packed double-precision (64-bit) floating-point elements in a, and store 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 2^-14.
