[−][src]

    pub unsafe fn _mm256_mask_fnmadd_pd(
        a: __m256d,
        k: __mmask8,
        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.
Expand description

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 a when the corresponding mask bit is not set).
