c - Can someone explain how this bitCount code works? - Stack Overflow

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 ... WebFeb 4, 2016 · Thus, it must result in a value of 0 to 32 (0 is when all is 0, 32 is when all is 8), which is the number of bit 1 in the variable x. And thus the function is named bitCount. That is how the function works. Final note: knowing this, you could even change m1 with 0x0F (instead of 0xFF) and the result would still be the same.
