Function surge_halfrate::imports::_mm256_mask_shldi_epi64

pub unsafe fn _mm256_mask_shldi_epi64<const IMM8: i32>(

    k: u8, 
    a: __m256i,

) -> __m256i

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

This is supported with target feature avx512vbmi2,avx512vl 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 writemask k (elements are copied from src when the corresponding mask bit is not set).
