1. ICS-603 Compiler 4 (3-1- 30 20 - 50 50 100
Design 0)
Prerequisite: Theory of Automata and Formal Languages (ECS-305)
Course Content:
Unit-1:
Introduction to Compiler, Phases and passes, Bootstrapping, Finite automata & regular
expressions and their applications to lexical analysis, Implementation of lexical analyzers,
lexical-analyzer generator, LEX-compiler, The syntactic specification of Programming
languages: Context free grammars, derivation and parse trees, capabilities of CFG,
Application of grammars in syntax analysis, ambiguity and BNF notation, YACC.
Unit-2:
Basic Parsing Techniques: Parsers, top down parsing, Shift reduces parsing, operator
precedence parsing, predictive parsers. Automatic Construction of efficient Parsers: LR
parsers, the canonical Collection of LR(0) items, constructing SLR parsing tables,
constructing Canonical LR parsing tables, Constructing LALR parsing tables, using
ambiguous grammars, an automatic parser generator, implementation of LR parsing tables,
constructing LALR sets of items.
Unit-3:
Syntax-directed Translation: Syntax-directed Translation schemes, Implementation of Syntax
directed Translators, Intermediate code, postfix notation, Parse trees & syntax trees, three
address code, quadruple & triples, translation of assignment statements, Boolean expressions,
statements that alter the flow of control, postfix translation, translation with a top down
parser. More about translation: Array references in arithmetic expressions, procedures call,
declarations, Case statements.
Unit-4:
Symbol Tables: Data structure and representing scope information, Run-Time
Administration: Implementation of simple stack allocation scheme, storage allocation in
block structured language. Error Detection & Recovery: Lexical Phase errors, syntactic phase
errors semantic errors.
Unit-5:
Introduction to code optimization: Loop optimization, the DAG representation of basic
blocks, value numbers and algebraic laws, Global Data-Flow analysis.

Course Outcomes:
1. Describe the role of each phase of a compiler with its construction tools. (Understand)
2. Develop a Lexical Analyzer for recognizing tokens of a given language with an understanding
of symbol table management and error handling. (Apply)
3. Construct top-down, bottom-up, operator precedence and SLR parsers with an
understanding of Context Free Grammars and syntax analysis. (Apply)
4. Design and develop semantic analyzers for type-checking and intermediate code generators
to translate the source program into an intermediate code. (Apply)
5. Construct code optimizers to optimize the target code generated. (Apply)
