Class BURS_IntConstantTreeNode

java.lang.Object
  org.jikesrvm.compilers.opt.lir2mir.ia32.BURS_TreeNode
      org.jikesrvm.ArchitectureSpecificOpt.BURS_TreeNode
          org.jikesrvm.compilers.opt.lir2mir.BURS_IntConstantTreeNode

All Implemented Interfaces:: BURS_Definitions

final class BURS_IntConstantTreeNode
extends ArchitectureSpecificOpt.BURS_TreeNode
extends ArchitectureSpecificOpt.BURS_TreeNode

A subclass of BURS_TreeNode for an IntConstantOperand. It is very common for us to want to access the value of an int constant during BURS, so we make it easy to do so by creating a special kind of node.
