Class ILOCProgram

java.lang.Object

edu.jmu.decaf.ILOCProgram

public class ILOCProgram
extends Object

Decaf program in ILOC intermediate representation (IR). Stores a symbol table for global symbols (basically the symbol table from an ASTProgram node) as well as a list of ILOC function objects. This class also handles allocation of sequential register and label IDs so that virtual registers and labels can continue to be generated after the initial AST-to-ILOC conversion.
