A RETARGETABLE C COMPILER DESIGN AND IMPLEMENTATION PDF

How to Obtain ICC. Working programmers use compilers every day and count heavily on their correctness and reliability. A compiler must accept the standard definition of the programming language so that source code will be portable across platforms. A compiler must generate efficient object code. Perhaps more important, a compiler must generate correct object code; an application is only as reliable as the compiler that compiled it. A compiler is itself a large and complex application that is worthy of study in its own right.

Compilers[ edit ] A retargetable compiler is a compiler that has been designed to be relatively easy to modify to generate code for different CPU instruction set architectures. The history of this idea dates back to the s when UNCOL was proposed as the universal intermediate language. The Pascal P-compiler is an example of an early widely used retargetable compiler. The cost of producing a retargetable compiler that generates code of similar quality to a non-retargetable compiler i.

The benefits of a retargetable compiler is that the total cost over multiple CPUs is much lower than the combined cost of many individual non-targetable compilers. Some retargetable compilers, e. A general-purpose global optimizer followed by machine-specific peephole optimization is a commonly used implementation technique. Unless developers invest the large amount of time necessary to write a code generator specifically for an architecture the optimizations performed by a retargetable compiler will only those applicable to generic processor characteristics.

A retargetable compiler is a kind of cross compiler. Often but not always a retargetable compiler is portable the compiler itself can run on several different CPUs and self-hosting.

Retargetable C Compiler, A: Design and Implementation

And while most books describe toy compilers or focus on isolated pieces of code, the authors have made available the entire source code for a real compiler. Structured as a self-study guide that describes the real-world tradeoffs encountered in building a production-quality compiler, A Retargetable C Compiler is also useful to individuals who work in application areas using or creating language-based tools and techniques. Features: discusses the implementation and design tradeoffs made while constructing a real ANSI C compiler, illustrating the interaction between theory and practice; covers compiler theory only as needed to understand the implementation of Icc, focusing instead on practical, applied issues; encourages a deeper understanding of programming in C, by providing C programmers with a tour of the language from the perspective of compiler authors; includes coverage of code generators for the MIPS R, SPARC, and Intel and its successors; and provides access to the full source code for the Icc compiler, the three back ends, and the code-generator generator, either on disk or via FTP.
