WebFor example, CPUs that support the popcnt instruction can theoretically compile __builtin_popcount into one instruction, which is much faster than usual implementations of this function. Similarly, if you want to auto-vectorize code, you'd need some instruction sets that actually support the vector instructions. WebOne of the top search hits has sample code and benchmarks for both native popcnt as well as the software version using pshufb. Their code requires MSVC, which I don't have access to, but their first popcnt implementation just calls the popcnt intrinsic in a loop, which is fairly easy to reproduce in a form that gcc and clang will accept.
