One of the problems with SIMD is that we can't do this kind of shuffle at bit granularity, at least not in one instruction.

- jeffffff 9y agoif you want bit level granularity you can use either SIMD-BP128 or SIMD-FastPFOR from https://arxiv.org/pdf/1209.2137.pdf https://arxiv.org/pdf/1209.2137.pdf
