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