Is there popcount () for Simulator and iOS device?

Question

The closest I can find is T popcount(T x)

in the Metal Standard Library .

Is there a simpler version like:

#include <x86intrin.h> 
__builtin_popcount();

which compiles well for the simulator, but not for the iPhone device ...

Not #include <x86intrin.h>

:

// #include <x86intrin.h> 
__builtin_popcount();
