WebJan 24, 2016 · 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. - PowerPoint PPT Presentation WebSyntax Directed Translation for syntax tree: Fig 3.4 SDT for syntax tree Three Address Code: Three address code is a sequence of statements of the general form x =y op z where x, y, and z are names, constants, or compiler-generated temporaries; • op stands for any operator such as a fixed- or floating-point arithmetic operator or a
