Web9 years ago, # . ← Rev. 3 → +22. __builtin_popcount (x) is a function in C++ returns the number of 1-bits set in an int x. In fact, "popcount" stands for "population count," so this is a function to determine how "populated" an integer is. For example, say we have an int x with value equal to 12. 12 in binary is just 1100, and the rest of ...
