Function core::arch::x86_64::_mm_mask3_fmsub_ss

pub unsafe fn _mm_mask3_fmsub_ss(
    a: __m128,
    b: __m128,
    c: __m128,
    k: __mmask8
) -> __m128

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

Available on x86-64 and target feature avx512f only.

Multiply the lower single-precision (32-bit) floating-point elements in a and b, and subtract the lower element in c from the intermediate result. Store the result in the lower element of dst using writemask k (the element is copied from c when mask bit 0 is not set), and copy the upper 3 packed elements from c to the upper elements of dst.
