Function _mm_mask_cmp_sd_mask

pub unsafe fn _mm_mask_cmp_sd_mask<const IMM8: i32>(
    k1: u8,
    a: __m128d,
    b: __m128d,
) -> u8

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86 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).
