Function core::arch::x86_64::_mm256_mask_test_epi8_mask

pub unsafe fn _mm256_mask_test_epi8_mask(
    k: __mmask32, 
    a: __m256i, 
    b: __m256i
) -> __mmask32

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on x86-64 and target feature avx512bw,avx512vl only.

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.
