Function core::arch::x86_64::_mm_mask_cmp_round_sd_mask

pub unsafe fn _mm_mask_cmp_round_sd_mask<const IMM5: i32, const SAE: i32>(
    k1: __mmask8, 
    a: __m128d, 
    b: __m128d
) -> __mmask8

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on x86-64 and target feature avx512f only.

Compare the lower double-precision (64-bit) floating-point element in a and b based on the comparison operand specified by imm8, and store the result in mask vector k using zeromask k1 (the element is zeroed out when mask bit 0 is not set).
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
