#[target_feature(enable = "avx512f")]
pub const fn _mm_mask_fmsub_ss(a: __m128, k: __mmask8, b: __m128, c: __m128) -> __m128Multiply 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, and copy the upper 3 packed elements from a to the upper elements of dst.
