Function core::arch::x86_64::_mm_maskz_shldv_epi64

pub unsafe fn _mm_maskz_shldv_epi64(
    k: __mmask8, 
    a: __m128i, 
    b: __m128i, 
    c: __m128i
) -> __m128i

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

Available on x86-64 and 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 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).
