This excellent book brilliantly provides both the theory and the design methodologies used in compiler designing as a result of the author's many years of study, teaching, research, and contact with students. The book provides readers with an overview of compilers, their design issues, and a detailed explanation of each phase of a compiler. The book familiarises the students with the compiler design tools. The contributions of these domains are especially highlighted because the process of building a compiler fundamentally draws on a variety of topics, including automata theory, data structures, algorithms, computer architecture, and operating systems. The most basic ones, like recursive descent and LL, to the most complex ones are all explained.
