构建嵌入式linux交叉编译环境

嵌入式产品的大量应用和linux系统的日趋完善，使嵌入式linux系统的开发得到广泛的重视。要进行嵌入式linux开发，软件方面的首要任务就是搭建适合自身开发平台的交叉编译环境。文章详细叙述了针对arm-i386硬件平台的嵌入式linux交叉编译环境构建方法，以及编译过程中一些错误的具体解决途径。     

HP-UX平台上GCC的安装与启用

针对系统盘不带GNu工具的HP-UX工作站，提供了一种在HP-UX工作站上安装从网上下载的一种已预编译成二进制代码的GCC软件包的方法，并且提供了测试、启用和删除已成功安装在此操作系统中的GCC软件包的方法。     

Compiler Hacking for Source Code Analysis

Many activities related to software quality assessment and improvement, such as empirical model construction, data flow analysis, testing or reengineering, rely on static source code analysis as the first and fundamental step for gathering the necessary input information. In the past, two different strategies have been adopted to develop tool suites. There are tools encompassing or implementing the source parse step, where the parser is internal to the toolkit, and is developed and maintained with it. A different approach builds tools on the top of external already-available components such as compilers that output the program abstract syntax tree, or that make it available via an API.This paper discusses techniques, issues and challenges linked to compiler patching or wrapping for analysis purposes. In particular, different approaches for accessing the compiler parsing information are compared, and the techniques used to decouple the parsing front end from the analysis modules are discussed.Moreover, the paper presents an approach and a tool, XOgastan, developed exploiting the gcc/g++ ability to save a representation of the intermediate abstract syntax tree. XOgastan translates the gcc/g++ dumped abstract syntax tree format into a Graph eXchange Language representation, which makes it possible to take advantage of currently available XML tools for any subsequent analysis step. The tool is illustrated and its design discussed, showing its architecture and the main implementation choices made.     

模调度与DFA结合的技术及其在gcc上的实现

循环是程序中的热代码,而软件流水是一种细粒度的循环优化方法,它通过将循环中不同迭代之间的操作并行执行,最大程度地开发指令级并行。模调度是一种效果很好的软件流水算法。论文以gcc3.3为基础,提出了模调度与DFA结合的软件流水方法,及其工程实现,实验数据表明,优化效果明显。
