pub unsafe fn _mm256_mask_popcnt_epi32(src: __m256i, k: u8, a: __m256i) -> __m256i
🔬This is a nightly-only experimental API. (stdsimd)
Available on x86-64 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.
