WebThe main application of Syntax-Directed Translation is in the construction of syntax trees. Compilers use syntax trees as an intermediate representation, using a common form of Syntax-Directed Definitions, the input string is converted into a tree.

Implement an SDT in conjunction with an LL-parser. – The attributes are kept on the parsing stack, and the rules fetch the needed attributes from known locations on the stack. D. Implement an SDT in conjunction with an LR-parser. – If the underlying grammar is LL, we can always handle both the parsing and translation bottom-up. 10

WebSyntax-directed translation refers to a method of compiler implementation where the source language translation is completely driven by the parser. In other words, the parsing process and parse trees are used to direct semantic analysis and the translation of the source program. This can be a separate phase of a compiler or we can augment
