Function _mm_reduce_round_sd
#[target_feature(enable = "avx512dq")]
pub fn _mm_reduce_round_sd(a: __m128d, b: __m128d, IMM8: i32, SAE: i32) -> __m128dExtract the reduced argument of the lower double-precision (64-bit) floating-point element in b by the number of bits specified by imm8, store the result in the lower element of dst, and copy the upper element from a to the upper element of dst. Rounding is done according to the imm8 parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT: round to nearest_MM_FROUND_TO_NEG_INF: round down_MM_FROUND_TO_POS_INF: round up_MM_FROUND_TO_ZERO: truncate_MM_FROUND_CUR_DIRECTION: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
