Function wiwi::rust_std::arch::x86_64::_mm_maskz_fmsub_sh

pub unsafe fn _mm_maskz_fmsub_sh(
    k: u8,
    a: __m128h,
    b: __m128h,
    c: __m128h,
) -> __m128h

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

Available on x86-64 only.

Multiply the lower half-precision (16-bit) floating-point elements in a and b, and subtract packed elements in c from the intermediate result. Store the result in the lower element of dst using zeromask k (the element is zeroed out when mask bit 0 is not set), and copy the upper 7 packed elements from a to the upper elements of dst.
