Description

 

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.

描述

設計為自學指南，本書描述了在建立一個生產品質、可重新定位平台的編譯器時所遇到的現實折衷。作者們檢視了lcc的實現，這是一個在AT&T貝爾實驗室為ANSI C編程語言設計的生產品質、研究導向的可重新定位編譯器。作者們創新的方法是一種「可讀程式」，將文本與源代碼交織在一起，通過對代碼的逐行解釋來展示lcc的構建過程。
