Function core::arch::x86::_mm512_maskz_shldv_epi64

pub unsafe fn _mm512_maskz_shldv_epi64(
    k: __mmask8,
    a: __m512i,
    b: __m512i,
    c: __m512i
) -> __m512i

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

Available on x86 and target feature avx512vbmi2 only.

Concatenate packed 64-bit integers in a and b producing an intermediate 128-bit result. Shift the result left by the amount specified in the corresponding element of c, and store the upper 64-bits in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
