# Function core::arch::x86_64::_mm512_maskz_popcnt_epi64
[−][src]

    pub unsafe fn _mm512_maskz_popcnt_epi64(k: __mmask8, a: __m512i) -> __m512i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512vpopcntdq` only.

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.
