Function _mm256_mask_popcnt_epi8

pub unsafe fn _mm256_mask_popcnt_epi8(
    src: __m256i,
    k: u32,
    a: __m256i,
) -> __m256i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86 only.

For each packed 8-bit integer maps the value to the number of logical 1 bits.

Uses the writemask in k - elements are copied from src if the corresponding mask bit is not set. Otherwise the computation result is written into the result.
