# Function core::arch::x86::_mm256_mask_rol_epi64
[−][src]

    pub unsafe fn _mm256_mask_rol_epi64(
        src: __m256i,
        k: __mmask8,
        a: __m256i,
        imm8: i32
    ) -> __m256i

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

Rotate the bits in each packed 64-bit integer in a to the left by the number of bits specified in imm8, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
