Function serde::lib::core::arch::x86_64::_mm512_maskz_shldi_epi64

pub unsafe fn _mm512_maskz_shldi_epi64<const IMM8: i32>(
    k: u8,
    a: __m512i,
    b: __m512i,

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

Concatenate packed 64-bit integers in a and b producing an intermediate 128-bit result. Shift the result left by imm8 bits, and store the upper 64-bits in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
