38 // The flag CompileThresholdScaling scales compilation thresholds
39 // in the following way:
40 //
41 // - if CompileThresholdScaling==1.0, the default threshold values
42 // are used;
43 //
44 // - if CompileThresholdScaling>1.0, threshold values are scaled
45 // up (e.g., CompileThresholdScalingPercentage=1.2 scales up
46 // thresholds by a factor of 1.2X);
47 //
48 // - if CompileThresholdScaling<1.0, threshold values are scaled
49 // down;
50 //
51 // - if CompileThresholdScaling==0, compilation is disabled
52 // (equivalent to using -Xint).
53 //
54 // With tiered compilation enabled, the values of the following
55 // flags are changed:
56 //
57 // Tier0InvokeNotifyFreqLog, Tier0BackedgeNotifyFreqLog,
58 // Tier3InvocationThreshold, Tier3MinInvocationThreshold,
59 // Tier3CompileThreshold, Tier3BackEdgeThreshold,
60 // Tier2InvokeNotifyFreqLog, Tier2BackedgeNotifyFreqLog,
61 // Tier3InvokeNotifyFreqLog, Tier3BackedgeNotifyFreqLog,
62 // Tier23InlineeNotifyFreqLog, Tier4InvocationThreshold,
63 // Tier4MinInvocationThreshold, Tier4CompileThreshold,
64 // Tier4BackEdgeThreshold
65 //
66 // With tiered compilation disabled the value of CompileThreshold
67 // is scaled.
