pub unsafe fn _mm_maskz_popcnt_epi64(k: __mmask8, a: __m128i) -> __m128i
🔬This is a nightly-only experimental API. (stdsimd #48556)
Available on (x86 or x86-64) and target feature avx512vpopcntdq,avx512vl and x86 only.
Expand description

For each packed 64-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.
