Function core::arch::x86_64::_mm512_mask_shrdv_epi64

pub unsafe fn _mm512_mask_shrdv_epi64(
    a: __m512i, 
    k: __mmask8, 
    b: __m512i, 
    c: __m512i
) -> __m512i

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

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

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