Function core::arch::x86::_mm256_mask3_fnmsub_pd

pub unsafe fn _mm256_mask3_fnmsub_pd(
    a: __m256d, 
    b: __m256d, 
    c: __m256d, 
    k: __mmask8
) -> __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, subtract packed elements in c from the negated intermediate result, and store the results in dst using writemask k (elements are copied from c when the corresponding mask bit is not set).
