# Function core::arch::x86_64::_mm256_aesdeclast_epi128
[−][src]

    pub unsafe fn _mm256_aesdeclast_epi128(
        a: __m256i,
        round_key: __m256i
    ) -> __m256i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512vaes,avx512vl` only.

Performs the last round of an AES decryption flow on each 128-bit word (state) in `a` using the corresponding 128-bit word (key) in `round_key`.
