[−][src]

    pub unsafe fn _mm256_mask_shuffle_i64x2<const MASK: i32>(
        src: __m256i,
        k: __mmask8,
        a: __m256i,
        b: __m256i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f,avx512vl` only.
Expand description

Shuffle 128-bits (composed of 2 64-bit integers) selected by imm8 from a and b, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
