Function core::arch::x86_64::_mm_mask_cmp_sd_mask

pub unsafe fn _mm_mask_cmp_sd_mask(
    k1: __mmask8, 
    a: __m128d, 
    b: __m128d, 
    const IMM8: i32
) -> __mmask8

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

Available 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).
