Function core::arch::x86::_mm256_shrdi_epi64

pub unsafe fn _mm256_shrdi_epi64<const IMM8: i32>(
    a: __m256i, 
    b: __m256i
) -> __m256i

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

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