CPUID from c++

a.cpp:

#include 
 
int main(int argc, char **argv) {
  int b;
  for (int a = 0; a < 5; a++) {
    asm ( "mov %1, %%eax; " // a into eax
          "cpuid;"
          "mov %%eax, %0;" // eeax into b
          :"=r"(b) /* output */
          :"r"(a) /* input */
          :"%eax" /* clobbered register */
         );
    std::cout << "The code " << a << " gives " << b << std::endl;
  }
  return 0;
}


# g++ a.cpp -o a

# exec ./a 

The code 0 gives 5
 The code 1 gives 3908
 The code 2 gives 1616597249

# echo "obase=16; 3908" | bc
