[−][src]

    pub unsafe fn _mm_mask_multishift_epi64_epi8(
        src: __m128i,
        k: __mmask16,
        a: __m128i,
        b: __m128i
    ) -> __m128i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512vbmi,avx512vl` only.
Expand description

For each 64-bit element in b, select 8 unaligned bytes using a byte-granular shift control within the corresponding 64-bit element of a, and store the 8 assembled bytes to the corresponding 64-bit element of dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
