Class OptEncodedCallSiteTree

java.lang.Object

org.jikesrvm.compilers.opt.runtimesupport.OptEncodedCallSiteTree

public abstract class OptEncodedCallSiteTree
extends Object

Suppose the following inlining actions have been taken

 (<callerMID, bcIndex, calleeMID>):

 <A, 12, B>, <A,14,C>, <A,16,D>, < B,3,E>, < B,5,F >, <C,10,G>, <G,20,H>,
 <H,30,I>
 

Then the OptEncodedCallSiteTree would be:

 -1, A, -2, 12, B, 14, C, 16, D, -6, 3, E, 5, F, -9, 10, G, -2, 20 H -2 30 I
