🔬This is a nightly-only experimental API. (
stdsimd
#48556)Available on (x86 or x86-64) and target feature
avx512vpopcntdq,avx512vl
and x86 only.Expand description
For each packed 64-bit integer maps the value to the number of logical 1 bits.
Uses the writemask in k - elements are zeroed in the result if the corresponding mask bit is not set. Otherwise the computation result is written into the result.
