#[target_feature(enable = "avx512f")]
pub fn _mm512_mask_cmp_round_pd_mask(k1: __mmask8, a: __m512d, b: __m512d, IMM5: i32, SAE: i32) -> __mmask8Compare packed double-precision (64-bit) floating-point elements in a and b based on the comparison operand specified by imm8, and store the results in mask vector k using zeromask k1 (elements are zeroed out when the corresponding mask bit is not set).
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
