CS308 Compiler Theory

CS308 Compiler Theory. Syntax-Directed Translation. Grammar symbols are associated with attributes to associate information with the programming language constructs that they represent. Values of these attributes are evaluated by the semantic rules associated with the production rules.

LESSON 28

LESSON 28. Overview of Previous Lesson(s). Over View. In syntax-directed translation we construct a parse tree or a syntax tree, and then to compute the values of attributes at the nodes of the tree by visiting the nodes of the tree.
