Function core::arch::x86::_mm256_mask3_fnmadd_pd

pub unsafe fn _mm256_mask3_fnmadd_pd(
    a: __m256d,
    b: __m256d,
    c: __m256d,
    k: __mmask8
) -> __m256d

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

Available on (x86 or x86-64) 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 writemask k (elements are copied from c when the corresponding mask bit is not set).
