Efficient Algorithm for Bit Reversal (from MSB->LSB to LSB->MSB) in C
...oughput. If your data is hot in L1D cache, the fastest way to popcount an array on Intel CPUs is with AVX2 pshufb. (Ryzen has 4 per clock popcnt throughput so that's probably optimal, but Bulldozer-family has one per 4 clocks popcnt r64,r64 throughput ... agner.org/optimize).
