Bottom up evaluation of sdt
WebBottom Up Evaluation of S Attribute • An attribute grammar is a formal way to define attributes for the productions of a formal grammar, associating these attributes to values. • The evaluation occurs in the nodes of the abstract syntax tree, when the language is processed by some parser or compiler. WebSynthesized attributes can be evaluated during any bottom-up traversal that is, a traversal that evaluates attributes at a node after having evaluated attributes at its children. In general, with both synthesized and inherited attributes, the matter of evaluation order is quite complex; see Section 5.2.
