A compiler translates a program written in a high level language into a program written in a lower level language. For students of computer science, building a compiler from scratch is a rite of passage: a challenging and fun project that offers insight into many different aspects of computer science, some deeply theoretical, and others highly practical. This book offers a one semester introduction into compiler construction, enabling the reader to build a simple compiler that accepts a C-like language and translates it into working X86 or ARM assembly language. It is most suitable for undergraduate students who have some experience programming in C, and have taken courses in data structures and computer architecture.

The second edition of this textbook has been fully revised and adds material about loop optimisation, function call optimisation and dataflow analysis. It presents techniques for making realistic compilers for simple programming languages, using techniques that are close to those used in "real" compilers, albeit in places slightly simplified for presentation purposes. All phases required for translating a high-level language to symbolic machine language are covered, including lexing, parsing, type checking, intermediate-code generation, machine-code generation, register allocation and optimisation, interpretation is covered briefly. Aiming to be neutral with respect to implementation languages, algorithms are presented in pseudo-code rather than in any specific programming language, but suggestions are in many cases given for how these can be realised in different language flavours. Introduction to Compiler Design is intended for an introductory course in compiler design, suitable for both undergraduate and graduate courses depending on which chapters are used.

The third edition of this textbook has been fully revised and adds material about the SSA form, polymorphism, garbage collection, and pattern matching. It presents techniques for making realistic compilers for simple to intermediate-complexity programming languages. The techniques presented in the book are close to those used in professional compilers, albeit in places slightly simplified for presentation purposes. "Further reading" sections point to material about the full versions of the techniques. All phases required for translating a high-level language to symbolic machine language are covered, and some techniques for optimising code are presented. Type checking and interpretation are also included. Aiming to be neutral with respect to implementation languages, algorithms are mostly presented in pseudo code rather than in any specific language, but suggestions are in many places given for how these can be realised in different language paradigms. Depending on how much of the material from the book is used, it is suitable for both undergraduate and graduate courses for introducing compiler design and implementation.

This is an introductory text for the undergraduate students of computer science and related courses studying compiler construction. The book was borne out of teaching compiler design in a way that the students should be able to understand compiler design in a simple form. This book will open the reader's understanding in preparation for a more complex aspect of the course.

This book is written with emphasis on practical programming examples, with inputs of theory and concepts behind the programming. The book is divided into two parts, the first part focusing on Advanced Unix programming and the second part on Compiler design. The book aims at providing a compatible way of attempting the problems through detailed algorithm and its implementation.Sailent FeaturesUnix programming and Compiler design focuses on Advanced Unix programming and gives the details about how to programme in shell environment with good examples followed by the programming examples and exercises.Compiler Design gives brief introduction of the phases followed by the algorithm and program implementation in C. with good explanation in detail about Compiler writing tools like LEX, YACC.At the end of each part, exercise questions are included with viva questions.
