🔬This is a nightly-only experimental API. (

#111137)Available on (x86 or x86-64) and target feature
avx512bitalg
and x86-64 only.Expand description
Considers the input b
as packed 64-bit integers and c
as packed 8-bit integers.
Then groups 8 8-bit values from c
as indices into the bits of the corresponding 64-bit integer.
It then selects these bits and packs them into the output.
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.
