evaluate method

E evaluate(
  1. SymbolTable table
)

Evaluates this AST node and generates corresponding LLVM IR code.

This is the main method that each AST node must implement to:

  1. Perform semantic analysis (type checking, symbol resolution)
  2. Generate LLVM IR instructions for the node's operation
  3. Return the result value (if this is an expression)

Parameters:

  • table: The current symbol table for variable and function lookups

Returns: The result of evaluating this node (type depends on node type)

Throws:

  • Exception for semantic errors (undefined variables, type mismatches, etc.)
  • Various specific exceptions for different error conditions

Note: The base implementation throws "Not implemented" - concrete subclasses must override this method with their specific evaluation logic.

Implementation

E evaluate(SymbolTable table) {
  throw Exception("Not implemented");
}
