# Function core::arch::x86_64::_mm256_test_epi64_mask
[−][src]

    pub unsafe fn _mm256_test_epi64_mask(a: __m256i, b: __m256i) -> __mmask8

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f,avx512vl` only.
Expand description

Compute the bitwise AND of packed 64-bit integers in a and b, producing intermediate 64-bit values, and set the corresponding bit in result mask k if the intermediate value is non-zero.
