Function core::arch::x86::_mm512_mask_popcnt_epi32

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

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

Available on x86 and target feature avx512vpopcntdq only.

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.
