# Function core::arch::x86::_mm512_mask_bitshuffle_epi64_mask[−][src]

    pub unsafe fn _mm512_mask_bitshuffle_epi64_mask(
        k: __mmask64,
        b: __m512i,
        c: __m512i
    ) -> __mmask64

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512bitalg` only.

Considers the input `b` as packed 64-bit integers and `c` as packed 8-bit integers. Then groups 8 8-bit values from `c`as indices into the the bits of the corresponding 64-bit integer. It then selects these bits and packs them into the output.

Uses the writemask in k - elements are zeroed in the result if the corresponding mask bit is not set. Otherwise the computation result is written into the result.
