| // The flag CompileThresholdScaling scales compilation thresholds |
| // in the following way: |
| // |
| // - if CompileThresholdScaling==1.0, the default threshold values |
| // are used; |
| // |
| // - if CompileThresholdScaling>1.0, threshold values are scaled |
| // up (e.g., CompileThresholdScalingPercentage=1.2 scales up |
| // thresholds by a factor of 1.2X); |
| // |
| // - if CompileThresholdScaling<1.0, threshold values are scaled |
| // down; |
| // |
| // - if CompileThresholdScaling==0, compilation is disabled |
| // (equivalent to using -Xint). |
| // |
| // With tiered compilation enabled, the values of the following |
| // flags are changed: |
| // |
| // Tier0InvokeNotifyFreqLog, Tier0BackedgeNotifyFreqLog, |
| // Tier3InvocationThreshold, Tier3MinInvocationThreshold, |

| // Tier4MinInvocationThreshold, Tier4CompileThreshold, |
| // Tier4BackEdgeThreshold |
| // |
| // With tiered compilation disabled the value of CompileThreshold |
| // is scaled. |
