Function no_std_compat::arch::x86_64::_mm512_mask_popcnt_epi64

pub unsafe fn _mm512_mask_popcnt_epi64(
    src: __m512i,
    k: u8,
    a: __m512i,
) -> __m512i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 only.

For each packed 64-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.
