Abstract Syntax Tree (AST)

AST Node classes in GeLB-v0

• Base class: ASTNode

• High-level classes:

  • List_N -- used often throughout the AST
  • Program_N -- root node for a complete program's AST
  • LatticeInstance_N
  • NodeClass_N
  • Initializer_N
  • Dynamic_N
  • Gauge_N
  • Function_N
  • Geometry_N
  • Expr_N
  • ConstantDeclaration_N
  • VariableDeclaration_N
  • Statement_N
    • VariableAssignmentStatement_N
    • RectangularSelectionOfLatticeOutDFsAssignmentStatement_N

• LiteralValue_N:

  • NumericLiteralValue_N
    • IntLiteralValue_N
      • ... (bitwidth-specific)
    • RealLiteralValue_N
      • ... (bitwidth-specific)
  • BooleanLiteralValue_N
  • StringLiteralValue_N -- used e.g. for simulation_name and simulation_description
  • ArrayLiteralValue_N
    • IntArrayLiteralValue_N
      • ... (bitwidth-specific)
    • RealArrayLiteralValue_N
      • ... (bitwidth-specific)
    • BoolArrayLiteralValue_N

• AST Node-classes which may be part of an Expr_N node:

  • Id_N

  • Expr_N (recursive!)
  • BinaryExpr_N
  • UnaryExpr_N
  • ExprAtom_N
    • LiteralValue_N
    • NonNegativeIntLiteral_N
    • NonNegativeFloatLiteral_N
    • BoolLiteral_N
    • FunctionCall_N
    • Id_N
    • ArrayLiteral_N
