Function core::arch::x86_64::_mm512_maskz_popcnt_epi8

pub unsafe fn _mm512_maskz_popcnt_epi8(k: __mmask64, a: __m512i) -> __m512i

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

Available on (x86 or x86-64) and target feature avx512bitalg only.

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.
