LCC ("Local C Compiler" or "Little C Compiler") is a small, retargetable compiler for the ANSI C programming language. Although its source code is available at no charge for personal use,[2] it is not open-source or free software according to the usual definitions because products derived from LCC may not be sold, although components not derived from LCC may be sold.[1] It was developed by Chris Fraser and David Hanson.
LCC is intended to be very simple to understand and is well-documented; its design is described in Fraser and Hanson's book A Retargetable C Compiler: Design and Implementation. The book includes most of the source code for version 3.6 of the compiler, which was written as a literate program using noweb. As of July 2011 the current version of LCC is 4.2, but much of the book still applies to this version. The major change since the book was published is in the code-generator interface, which is described in a separate document.[3]

Designed as a self-study guide, the book describes the real-world tradeoffs encountered in building a production-quality, platform-retargetable compiler. The authors examine the implementation of lcc, a production-quality, research-oriented retargetable compiler, designed at AT&T Bell Laboratories for the ANSI C programming language. The authors' innovative approach-a "literate program" that intermingles the text with the source code-uses a line-by-line explanation of the code to demonstrate how lcc is built.
This new text examines the design and implementation of lcc, a production-quality, retargetable compiler for the ANSI C programming language, designed at AT&T Bell Laboratories and Princeton University. The authors' innovative approach--a "literate program" that intermingles the text with the source code--gives a detailed tour of the code that explains the implementation and design decisions reflected in the software. And while most books describe toy compilers or focus on isolated pieces of code, the authors provide the entire source code for a real compiler, which is available via ftp. Structured as a self-study guide that describes the real-world tradeoffs encountered in building a production-quality compiler, this book is useful to individuals who work in application areas applying or creating language-based tools and techniques.
Since 1975, Christopher W. Fraser has researched compiling, particularly producing code generators automatically from compact specs, and has published many technical articles in this area. He originated retargetable peephole optimization, which GCC, a popular C compiler, uses to help select instructions. From 1977 until 1986, Fraser taught computer science, including compiling, at the University of Arizona. Since 1986, Fraser has conducted computing research at AT&T Bell Laboratories in Murray Hill, New Jersey.
We present a novel approach which combines compiler, instruction set, and microarchitecture support to turn off functional units that are idle for long periods of time for reducing static power dissipation by idle functional units using power gating [2],[9]. The compiler identifies program regions in which functional units are expected to be idle and communicates this information to the hardware by issuing directives for turning units off at entry points of idle regions and directives for turning them back on at exits from such regions. The microarchitecture is designed to treat the compiler directives as hints ignoring a pair of off and on directives if they are too close together. The results of experiments show that some of the functional units can be kept off for over 90% of the time at the cost of minimal performance degradation of under 1%.
I prefer Modern Compiler Implementation to the Dragon book because Modern Compiler implementation surveys less of the field--instead it has really solid coverage of all the topics you would need to write a serious, decent compiler. After you work through this book you'll be ready to tackle research papers directly for more depth if you need it.
The language required is Pascal and if I remember correctly is based on Turbo-Pascal. It just so happens if you go to and download the Pascal compiler all the examples work straight from the page The beaut thing about Free Pascal is you can use it almost whatever processor or OS you can care for.
This unfortunately-titled bookexplains the design and creation of a single-user programming environmentfor micros, using a Pascal-like language called Edison. The author presentsall source code and explanations for the step-by-step implementation of anEdison compiler and simple supporting operating system, all written inEdison itself (except for a small supporting kernel written in a symbolicassembler for PDP 11/23; the complete source can also be ordered for the IBMPC).
The most interesting things about this book are: 1) its ability todemonstrate how to create a complete, self-contained, self-maintaining,useful compiler and operating system, and 2) the interesting discussion oflanguage design and specification problems and trade-offs in Chapter 2.
Another light-on-theoryheavy-on-pragmatics here's-how-to-code-it book. The author presents thedesign, implementation, and complete source code for a compiler and p-codeinterpreter for Pascal- (Pascal "minus"), a Pascal subset with boolean andinteger types (but no characters, reals, subranged or enumerated types),constant and variable definitions and array and record types (but no packed,variant, set, pointer, nameless, renamed, or file types), expressions,assignment statements, nested procedure definitions with value and variableparameters, if statements, while statements, and begin-end blocks (but nofunction definitions, procedural parameters, goto statements and labels,case statements, repeat statements, for statements, and with statements).
This book makes the design and implementation of a compiler look easy. Iparticularly like the way the author is concerned with quality,reliability, and testing. The compiler and interpreter can easily be usedas the basis for a more involved language or compiler project, especiallyif you're pressed to quickly get something up and running.
I got a book called Project Oberon more than a decade ago, which has some very well written text on the compiler. The book really stands out in the sense that the source and explanations is very hands on and readable. The complete text (the 2005 edition) has been made available in pdf, so you can download right now. The compiler is discussed in chapter 12: 2ff7e9595c
