public CompilerTools()
Method Detail

finalizePayload

public static ASTLinkedList finalizePayload(ASTLinkedList astLinkedList,
                                            boolean secondPassOptimization,
                                            ParserContext ctx)
Finalize the payload, by reducing any stack-based-operations to dedicated nodes where possible.

Parameters:
astLinkedList - - AST to be optimized.
secondPassOptimization - - perform a second pass optimization to optimize boolean expressions.
ctx - - The parser context
Returns:
optimized AST
