[−][src]

    pub unsafe fn _mm512_mask_popcnt_epi32(
        src: __m512i,
        k: __mmask16,
        a: __m512i
    ) -> __m512i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512vpopcntdq` 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 copied from src if the corresponding mask bit is not set. Otherwise the computation result is written into the result.
