Function core::arch::x86::_mm512_mask_sll_epi64

pub unsafe fn _mm512_mask_sll_epi64(
    src: __m512i,
    k: __mmask8,
    a: __m512i,
    count: __m128i
) -> __m512i

🔬 This is a nightly-only experimental API. (stdsimd #48556)

Available on x86 and target feature avx512f only.

Shift packed 64-bit integers in a left by count while shifting in zeros, and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
