# Function core::arch::x86::_mm_mask_cmp_pd_mask
[−][src]

    pub unsafe fn _mm_mask_cmp_pd_mask(
        k1: __mmask8,
        a: __m128d,
        b: __m128d,
        imm8: i32
    ) -> __mmask8

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512f,avx512vl` only.

Compare 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).
