Function core::arch::x86_64::_mm256_mask_shldi_epi16

pub unsafe fn _mm256_mask_shldi_epi16(
    src: __m256i, 
    k: __mmask16, 
    a: __m256i, 
    b: __m256i,

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

This is supported on x86-64 and target feature avx512vbmi2,avx512vl only.

Concatenate packed 16-bit integers in a and b producing an intermediate 32-bit result. Shift the result left by imm8 bits, and store the upper 16-bits in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
