Function core::arch::x86_64::_mm_mask_fmaddsub_pd

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

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on (x86 or x86-64) and target feature avx512f,avx512vl and x86-64 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).
