41 // The flag CompileThresholdScaling scales compilation thresholds
42 // in the following way:
43 //
44 // - if CompileThresholdScaling==1.0, the default threshold values
45 // are used;
46 //
47 // - if CompileThresholdScaling>1.0, threshold values are scaled
48 // up (e.g., CompileThresholdScalingPercentage=1.2 scales up
49 // thresholds by a factor of 1.2X);
50 //
51 // - if CompileThresholdScaling<1.0, threshold values are scaled
52 // down;
53 //
54 // - if CompileThresholdScaling==0, compilation is disabled
55 // (equivalent to using -Xint).
56 //
57 // With tiered compilation enabled, the values of the following
58 // flags are changed:
59 //
60 // Tier0InvokeNotifyFreqLog, Tier0BackedgeNotifyFreqLog,
61 // Tier3InvocationThreshold, Tier3MinInvocationThreshold,
62 // Tier3CompileThreshold, Tier3BackEdgeThreshold,
63 // Tier2InvokeNotifyFreqLog, Tier2BackedgeNotifyFreqLog,
64 // Tier3InvokeNotifyFreqLog, Tier3BackedgeNotifyFreqLog,
65 // Tier23InlineeNotifyFreqLog, Tier4InvocationThreshold,
66 // Tier4MinInvocationThreshold, Tier4CompileThreshold,
67 // Tier4BackEdgeThreshold
68 //
69 // With tiered compilation disabled the value of CompileThreshold
70 // is scaled.
