Overflow corrected #82

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
            if (old_val_CORE[ii] > new_val_CORE[ii]) {                  //handle overflow
                CPU_CLK_UNHALTED_CORE = (UINT64_MAX - old_val_CORE[ii]) + new_val_CORE[ii];

may be corrected by

            if (old_val_CORE[ii] > new_val_CORE[ii]) {                  //handle overflow
                CPU_CLK_UNHALTED_CORE = (UINT64_MAX - new_val_CORE[ii]) + old_val_CORE[ii];

I'm programming XFreq and this is the formula which gives me good results when 
showing Turbo.
