RDTSCP instruction reads the current value of the processor’s time-stamp counter (a 64-bit MSR) into the EDX:EAX registers, and it also reads the value of the IA32_TSC_AUX MSR (address C0000103H) into the ECX register. However, the current RDTSCP implementation does not provide a hint for the compiler that ECX has been changed, resulting in register corrupted and subtle errors.
