示例1: specialize
import jdk.nashorn.internal.ir.Assignment; //導入依賴的package包/類
<T extends Expression> SpecializedNode specialize(final Assignment<T> assignment) {
final Node node = ((Node)assignment);
final T lhs = assignment.getAssignmentDest();
final Expression rhs = assignment.getAssignmentSource();
if (!canHaveCallSiteType(lhs)) {
return new SpecializedNode(node, null);
}
final Type to;
if (node.isSelfModifying()) {
to = node.getWidestOperationType();
} else {
to = rhs.getType();
}
if (!isSupportedCallSiteType(to)) {
//meaningless to specialize to boolean or object
return new SpecializedNode(node, null);
}
final Node newNode = assignment.setAssignmentDest(setTypeOverride(lhs, to));
final Node typePropagatedNode;
if(newNode instanceof Expression) {
typePropagatedNode = propagateType((Expression)newNode, to);
} else if(newNode instanceof VarNode) {
// VarNode, being a statement, doesn't have its own symbol; it uses the symbol of its name instead.

} else {
