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