#[target_feature(enable = "avx512f")]
pub fn _mm_mask_mul_round_sd(src: __m128d, k: __mmask8, a: __m128d, b: __m128d, ROUNDING: i32) -> __m128dMultiply the lower double-precision (64-bit) floating-point element in a and b, store the result in the lower element of dst using writemask k (the element is copied from src when mask bit 0 is not set), and copy the upper element from a to the upper element of dst.\
Rounding is done according to the rounding[3:0] parameter, which can be one of:\
_MM_FROUND_TO_NEAREST_INT|_MM_FROUND_NO_EXC: round to nearest and suppress exceptions_MM_FROUND_TO_NEG_INF|_MM_FROUND_NO_EXC: round down and suppress exceptions_MM_FROUND_TO_POS_INF|_MM_FROUND_NO_EXC: round up and suppress exceptions_MM_FROUND_TO_ZERO|_MM_FROUND_NO_EXC: truncate and suppress exceptions_MM_FROUND_CUR_DIRECTION: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
