pub unsafe fn _mm256_maskz_popcnt_epi32(k: __mmask8, a: __m256i) -> __m256i
🔬This is a nightly-only experimental API. (stdsimd #48556)
Available on (x86 or x86-64) and target feature avx512vpopcntdq,avx512vl and x86-64 only.
Expand description

For each packed 32-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.
