Function core::arch::x86::_mm256_mask_fnmadd_ph

pub unsafe fn _mm256_mask_fnmadd_ph(
    a: __m256h,
    k: __mmask16,
    b: __m256h,
    c: __m256h,
) -> __m256h

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on (x86 or x86-64) and target feature avx512fp16,avx512vl and x86 only.

Multiply packed half-precision (16-bit) floating-point elements in a and b, subtract the intermediate result from packed elements in c, and store the results in dst using writemask k (the element is copied from a when the corresponding mask bit is not set).
