A compiler is a program that translates a source program written in a high-level language into an equivalent target program written in a low-level language. The process of compilation involves several phases, each of which performs a specific task on the source program. The main goal of a compiler is to produce correct, efficient, and portable code for the target machine.
Compiler design is a branch of computer science that deals with the theory and practice of developing compilers. It requires knowledge of various topics such as formal languages, automata theory, data structures, algorithms, computer architecture, and operating systems. Compiler design is also a challenging and rewarding field that offers many opportunities for research and innovation.
Overview of Compilation
The book Principles of Compiler Design by A.A. Puntambekar begins with an overview of the compilation process and its phases. It explains the basic concepts and terminology used in compiler design, such as tokens, lexemes, grammars, syntax trees, intermediate code, etc. It also introduces some tools that can help in building compilers, such as LEX and YACC.
The book then describes each phase of compilation in detail, starting from lexical analysis. Lexical analysis is the phase that scans the source program and converts it into a sequence of tokens. Tokens are the smallest meaningful units of a program, such as keywords, identifiers, literals, operators, etc. Lexical analysis involves recognizing the patterns of characters that form tokens using regular expressions and finite automata.
Top Down Parsing
Parsing is the phase that analyzes the syntactic structure of the source program and checks if it conforms to the rules of the grammar. Parsing also constructs a parse tree or an abstract syntax tree that represents the hierarchical relationship between the tokens. Parsing can be done in two ways: top down or bottom up.
Top down parsing is a method that starts from the root or the start symbol of the grammar and tries to match the input tokens with the productions of the grammar. Top down parsing can be done using recursive descent or predictive parsing techniques. Recursive descent parsing is a simple but inefficient method that uses a set of recursive procedures to parse each nonterminal symbol. Predictive parsing is a more efficient method that uses a table-driven approach to determine which production to apply based on the current input token and the top of the stack.
Bottom Up Parsing
Bottom up parsing is a method that starts from the input tokens and tries to reduce them to the root or the start symbol of the grammar. Bottom up parsing can be done using shift reduce or LR parsing techniques. Shift reduce parsing is a simple but ambiguous method that uses a stack to store symbols and performs two operations: shift (pushing an input token onto the stack) or reduce (popping symbols from the stack and replacing them with a nonterminal symbol according to a production). LR parsing is a more powerful and unambiguous method that uses a finite state machine and a stack to guide the parsing process based on the current state and input token.
Semantic analysis is the phase that checks if the source program has any semantic errors or inconsistencies, such as type mismatches, undeclared variables, illegal operations, etc. Semantic analysis also annotates the syntax tree with additional information such as types, values, scopes, etc., that are needed for later phases.
Semantic analysis involves using attributed grammars and syntax directed translation techniques to define and compute semantic attributes for each node of the syntax tree. Attributed grammars are extensions of context free grammars that associate attributes (such as type, value, scope, etc.) with grammar symbols and rules. Syntax directed translation is a method that specifies how to compute attribute values using semantic rules or actions associated with grammar productions.
Symbol tables are data structures that store information about symbols (such as names, types, values, scopes, etc.) used in a source program. Symbol tables are essential for semantic analysis and code generation phases.
The book Principles of Compiler Design by A.A. Puntambekar explains how to design and implement symbol tables using various techniques such as hashing, chaining, nesting, etc. It also discusses how to handle scope information for block structured languages using tree structures or stack based mechanisms.
Block Structures and Non Block Structure Storage Allocation
Storage allocation is the phase that determines how much memory space is needed for each variable or data structure used in a source program. Storage allocation can be done statically (at compile time) or dynamically (at run time) depending on whether the size and lifetime of variables are known beforehand or not.
The book Principles of Compiler Design by A.A. Puntambekar covers various methods for static and dynamic storage allocation for block structured languages (such as C) and non block structured languages (such as FORTRAN). It explains how to use runtime stack and heap memory for storing local variables, arrays, strings, records, etc.
Code optimization is the phase that improves the quality and efficiency of the intermediate code generated by previous phases. Code optimization aims to eliminate redundant or unnecessary code, reduce execution time or memory space requirements, enhance performance or portability, etc.
The book Principles of Compiler Design by A.A. Puntambekar covers various techniques for local and global code optimization, such as constant folding, common subexpression elimination, loop optimization, strength reduction, dead code elimination, induction variable elimination, live variable analysis, copy propagation, etc. It also explains how to use data flow analysis methods to compute useful information about the flow of data values in a program and use it for optimization purposes.
Data Flow Analysis
Data flow analysis is a technique that computes useful information about the flow of data values in a program by solving data flow equations on a flow graph representation of the program. Data flow analysis can be used for various purposes, such as code optimization, error detection, program testing, program verification, etc.
The book Principles of Compiler Design by A.A. Puntambekar
explains how to construct flow graphs from intermediate code and how to define and solve data flow equations using fixed point iteration methods. It also discusses various types of data flow analyses, such as reaching definitions analysis, available expressions analysis, live variables analysis, etc.
Object Code Generation
Object code generation is the final phase of compilation that translates the intermediate code into an equivalent target code for the target machine. Object code generation involves various tasks, such as instruction selection, register allocation, code scheduling, peephole optimization, etc.
The book Principles of Compiler Design by A.A. Puntambekar
explains how to generate object code using generic code generation algorithms based on directed acyclic graphs (DAGs) or trees. It also discusses how to perform machine dependent code optimization using techniques such as register allocation and assignment, code scheduling, peephole optimization, etc.
