How are programs written in a high-level language transformed into machine code? Yet the models, theory, and algorithms associ ated with a compiler can be applied to a wide range of problems in software design and software development. The textbook covers compiler design theory, as well as implementation details for writing a compiler using JavaCC and Java. Compiler design is an important part of the undergraduate curriculum for many reasons What is this course about? Basic Architecture. It then uses this structure to create an intermediate representation of the source program. The most well known form of a compiler is one that translates a high-level language like C into the native assembly language of a machine so thatSee more Programming Language Basics. Compilers and Interpreters. Lexing ContentsIntroductionWhat is a compiler?The phases of a compiler We recognize that few readers will build, or even maintain, a compiler for a major programming language. We therefore emphasize problems that are This document is a companion to the textbook Modern Compiler Design by David Galles. It is a subject which has been studied intensively since the early ’s and continues to be an important research field today. How can we ensure a program is somewhat meaningful? There are two parts to compilation: Analysis breaks up the source program into constituent pieces and imposes a grammatical structure on them. Translation of a program written in a source language into a semantically equivalent program written in a target language. Compilers and Interpreters (cont) IntroductionWhat is a compiler?Why should you study compilers?What’s the best way to learn about compilers?What language should I use? Performing the operations implied by the source program. How can we analyze programs to discover invariant properties and improve their runtime performance? Compilation. compiler translates a program in a source language to a program in target language. Front end. Compilers and Interpreters (cont) Interpretation. How is the program’s memory managed? The analysis part also collects information about the source program and stores it in a This document contains all of the implementation details for writing a compiler using C, Lex, and Yacc LIST OF FIGURES xiii List of Figures A Typical Compiler ToolchainThe Stages of a Unix Compiler Analysis and Synthesis. 2 Compiler design is a subject which many believe to be fundamental and vital to computer science.
