Use of Assembly Language in High-Level Languages
This example simply executes the RDTSC assembly instruction, which reads
the CPU's timestamp counter, then stores the higher 32 bits into the EDX
register and the lower ones into the EAX register. The value of EAX is then
assigned to the timeStampCounter variable in C++ and printed out:
1
2

// {
#include <iostream>
using namespace std;
// }
int main() {
uint timeStampCounter = 0;
asm("rdtsc": "=a" (timeStampCounter));
std::cout << timeStampCounter << std::endl;
return 0;
}
