Function core::arch::x86::_mm_maskz_shrdi_epi64

pub unsafe fn _mm_maskz_shrdi_epi64(
    k: __mmask8,
    a: __m128i,
    b: __m128i,
    const IMM8: i32
) -> __m128i

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

Available on (x86 or x86-64) and target feature avx512vbmi2,avx512vl and x86 only.

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