* Get_CPU_Clock -- Fetches the current CPU clock time. *
* *
* This routine will return the internal Pentium clock accumulator. This accumulator is *
* incremented every clock tick. Since this clock value can get very very large, the value *
* returned is in 64 bits. The low half is returned directly, the high half is stored in *
* location specified. *
* *
* INPUT: high -- Reference to the high value of the 64 bit clock number. *
* *
* OUTPUT: Returns with the low half of the CPU clock value. *
* *
* WARNINGS: This instruction is only available on Pentium or later processors. *
* *
* HISTORY: *
* 07/17/1996 JLB : Created. *
