Function core::arch::x86_64::_mm256_mask_popcnt_epi32

pub unsafe fn _mm256_mask_popcnt_epi32(
    src: __m256i, 
    k: __mmask8, 
    a: __m256i
) -> __m256i

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

This is supported on x86-64 and target feature avx512vpopcntdq,avx512vl 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.
