# Function core::arch::x86_64::_mm256_shldi_epi64
[−][src]

    pub unsafe fn _mm256_shldi_epi64(a: __m256i, b: __m256i, imm8: i32) -> __m256i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512vbmi2,avx512vl` 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).
