Function core::arch::x86::_mm_shrdi_epi64

pub unsafe fn _mm_shrdi_epi64(
    a: __m128i, 
    b: __m128i, 
    const IMM8: i32
) -> __m128i

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

Available 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.
