WebBitcount is a cross-platform implementation of GCC's intrinsic __builtin_clz, __builtin_ctz, and __builtin_popcount. Currently only intrinsic functions are used in VS 2012 (possibly older VS versions as well), and GCC-compatible compilers (including Clang). If Bitcount is used on a system that isn't either of these, it uses a C implementation ...
