Just out of curiosity, is this the instruction that is called by then Win32
API call QueryPerformanceCounter? And on what platforms is it available?
MSDN states "Some systems include a high-resolution performance counter that
provides high-resolution elapsed times." But is doesn't get anymore
specific, and my search on the web hasn't returned any useful information
either. Does anybody know this?
