pub const fn _mm_mask_fmaddsub_ps(a: __m128, k: __mmask8, b: __m128, c: __m128) -> __m128Multiply packed single-precision (32-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).
