      public IExpression analyze(Context context)
      Analyzes and returns an IExpression.
      Specified by:
      analyze in class IExpression
      Parameters:
      context - context in which names are resolved.
      Returns:

    • codegen

      public void codegen(CLEmitter output)
      Performs code generation for this AST.
      Specified by:
      codegen in class IAST
      Parameters:
      output - the code emitter.
    • codegen

      public void codegen(CLEmitter output, String targetLabel, boolean onTrue)
      Performs short-circuit code generation for a boolean expression, given the code emitter, a target label, and whether we branch to that label on true or on false.
      Overrides:
      codegen in class IExpression
      Parameters:
      output - the code emitter.
      targetLabel - the label to which we should branch.
