_mm_bitshuffle_epi64_mask in core::arch::x86 - Rust
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.
