question: @ Override public Label conditionalJump ( int index , Condition condition ) { Label label ; if ( conditionalLabelPointer <= conditionalLabels . size ( ) ) { label = new Label ( ) ; conditionalLabels . add ( label ) ; conditionalLabelPointer = conditionalLabels . size ( ) ; } else { label = conditionalLabels . get ( conditionalLabelPointer ++ ) ; } conditionalJump ( index , condition , label ) ; return label ; }
target:  This method caches the generated labels over two assembly passes to get information about branch lengths.
