Member Function Documentation

virtual ExprASTNode* elftosb::ExprASTNode::reduce ( EvalContext &  context)
inlinevirtual

Evaluate the expression and produce a result node to replace this one.

The default implementation simply return this node unmodified. This method is responsible for deleting any nodes that are no longer needed. (?) how to delete this?

Reimplemented in elftosb::IntSizeExprASTNode, elftosb::BinaryOpExprASTNode, elftosb::SizeofOperatorASTNode, elftosb::DefinedOperatorASTNode, elftosb::SourceFileFunctionASTNode, elftosb::BooleanNotExprASTNode, elftosb::NegativeExprASTNode, elftosb::SymbolRefExprASTNode, and elftosb::VariableExprASTNode.
