Part 1 of book "Compilers: Principles, Techniques, and Tools (Second Edition)" provide students with knowledge about: background issues in computer architecture and programming-language principles; develops a miniature compiler and introduces many of the important concepts; lexical analysis, regular expressions, nite-state machines, and scanner-generator tools; the major parsing methods, top-down (recursive-descent, LL) and bottom-up (LR and its variants);...

The purpose of the syntactic analyzer, or parser, is to construct a parse tree using as input the stream of tokens provided by the lexer. The output of the parser is usually an abstract syntax tree. The motivation for using an abstract syntax tree, rather than a parse tree. Chapter 3 - Lexical and syntactic analysis: Syntactic analysis.

In computer science, a recursive descent parser is a kind of top-down parser built from a set of mutually recursive procedures (or a non-recursive equivalent) where each such procedure usually implements one of the productions of the grammar. In this lecture will introduce recursive descent (RD) parser. Inviting you to refer for more detail.

A purely functional implementation of LR-parsers is given, together with a simple correctness proof. It is presented as a generalization of the recursive descent parser. For non-LR grammars the time-complexity of our parser is cubic if the functions that constitute the parser are implemented as memo-functions, i.e. functions that memorize the results of previous invocations. Memo-functions also facilitate a simple way to construct a very compact representation of the parse forest.

This paper discusses a sequence of deductive parsers, called PAD1 - PAD5, that utilize an a x i o m a t i z a t i o n of the p r i n c i p l e s a n d parameters of GB theory, including a restricted transformational component (Move-a). PAD2 uses an inference control strategy based on the "freeze" predicate of Prolog-II, while PAD3 - 5 utilize the Unfold-Fold transformation to transform the original axiomatization into a form that functions as a recursive descent Prolog parser for the fragment. INTRODUCTION In this paper I...
