Classes in edu.jmu.decaf used by edu.jmu.decaf

Class and Description
ASTAssignment Decaf assignment statement.
ASTBinaryExpr Decaf binary operation with an operation tag and two child sub-expressions.
ASTBinaryExpr.BinOp List of permitted binary operations.
ASTBlock Lexical scope in a Decaf program; e.g., a function body or a while-loop body.
ASTBreak Decaf "break" statement (should be inside a loop structure).
ASTConditional Decaf control structure; a block of code that is only executed if the condition is true when the code is encountered during execution.
ASTContinue Decaf "continue" statement (should be inside a loop structure).
ASTExpression Any Decaf expression that can be evaluated to a value at runtime.
ASTFunction Decaf function declaration.
ASTFunction.Parameter Decaf formal parameter (name and data type).
ASTFunctionCall Decaf function call that is intended to return a value at runtime.
ASTLiteral Decaf literal value.
ASTLocation Decaf location.
ASTNode Abstract base class for abstract syntax tree (AST) nodes.
ASTNode.DataType List of Decaf AST data types.
ASTProgram Decaf program.
ASTReturn Decaf "return" statement (should be inside of a function).
ASTStatement Any Decaf statement that can be executed at runtime.
ASTUnaryExpr Unary operation with an operation tag and a child sub-expression.
ASTUnaryExpr.UnaryOp List of permitted unary operations.
ASTVariable Decaf variable declaration.
ASTVisitor Definition of a Visitor interface for AST trees.
ASTVoidFunctionCall Decaf function call that is NOT intended to return a value.
ASTWhileLoop Decaf loop structure; contains a "guard" expression and a loop body block.
DecafAnalysis Static analysis; perform type checking.
DecafLexer "Stub" Decaf lexer.
DecafParser "Stub" Decaf parser.
DefaultASTVisitor Basic "stub" implementation of the ASTVisitor interface.
ILOCBasicBlock
ILOCFunction Decaf function in ILOC intermediate representation (IR).
ILOCGenerator AST post-visitor; converts a Decaf program in AST IR to ILOC IR by walking the tree and recursively emitting sequential IR.
ILOCInstruction Represents a single ILOC instruction in a pseudo-triple format, including a "form" indicator (enum) and up to three operands, which can represent virtual register IDs, special registers, constants, or jump/call targets.
ILOCInstruction.Form Possible forms of an ILOC instruction
ILOCOperand Single ILOC instruction operand: a register (named or virtual), a jump/call label, an integer constant, or a string constant.
ILOCOperand.Type
ILOCProcessor All ILOC processing passes (static analysis, optimization, machine code generation, etc.) should implement this (admittedly simple) standardized interface.
ILOCProgram Decaf program in ILOC intermediate representation (IR).
InvalidInstructionException Error encountered during execution.
InvalidProgramException Error encountered during static/semantic analysis.
InvalidSyntaxException Error encountered during parsing.
InvalidTokenException Error encountered during lexing.
LocalRegisterAllocator Performs register allocation for an ILOC program.
SourceInfo Stores information about a location in a program's source code.
StaticAnalysis Provides a mechanism for aggregating InvalidProgramException errors from any AST static analysis pass.
Symbol Single Decaf symbol.
Symbol.MemLoc Memory access locations.
SymbolTable Stores name-to-symbol-info mappings for a single lexical scope.
Token Data structure that represents a single token of a Decaf program.
Token.Type Token type.
