pub unsafe fn _mm256_maskz_popcnt_epi8(k: u32, a: __m256i) -> __m256i
🔬 This is a nightly-only experimental API. (stdsimd)
This is supported on x86-64 and target feature avx512bitalg,avx512vl only.
Expand description

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

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