Function core::arch::x86::_mm_mask_fmaddsub_pd

pub unsafe fn _mm_mask_fmaddsub_pd(
    a: __m128d,
    k: __mmask8,
    b: __m128d,
    c: __m128d
) -> __m128d

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

Available on x86 and target feature avx512f,avx512vl only.

Multiply packed double-precision (64-bit) floating-point elements in a and b, alternatively add and subtract packed elements in c to/from the intermediate result, and store the results in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
