Function core::arch::x86::_mm_shldi_epi64

pub unsafe fn _mm_shldi_epi64(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 a and b producing an intermediate 128-bit result. Shift the result left by imm8 bits, and store the upper 64-bits in dst).
