Function core::arch::x86::_mm256_maskz_fnmadd_pd

pub unsafe fn _mm256_maskz_fnmadd_pd(
    k: __mmask8, 
    a: __m256d, 
    b: __m256d, 
    c: __m256d
) -> __m256d

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

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

Multiply packed double-precision (64-bit) floating-point elements in a and b, add the negated intermediate result to packed elements in c, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
