# Function core::arch::x86::_mm512_mask_test_epi8_mask
[−][src]

    pub unsafe fn _mm512_mask_test_epi8_mask(
        k: __mmask64,
        a: __m512i,
        b: __m512i
    ) -> __mmask64

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512bw` only.
Expand description

Compute the bitwise AND of packed 8-bit integers in a and b, producing intermediate 8-bit values, and set the corresponding bit in result mask k (subject to writemask k) if the intermediate value is non-zero.
