一种统一的调试信息管理方法

A Uniform Method to Manage Debugging Information

调试信息的分析和管理是调试系统的重要组成部分。调试信息在被调试文件中的存储格式有很多种。一个成熟的调试系统需要支持分析和管理多种格式的调试信息。BWDSP芯片的调试系统使用一种统一的调试信息管理方法。不同格式的调试信息经过分析后可以转换为统一的格式。调试系统的其他模块在使用调试信息时不需要关心被调试文件的调试信息格式,可以以统一的方式使用调试信息。经实践证明该方法可以以统一的方式管理C语言文件的DWARF和STABS格式的调试信息。

The analysis and management of debugging information is an important component of a debugger system. There are many forms to store debugging information in executable files. A mature debugger system should support to analyze and manage various forms of debugging information. A uniform method to manage debugging information is proposed in BWDSP＇ s debugger system. Debugging information of different forms can be transformed into a universal form by this method. Other modules of debugger system can neglect forms of debugging information and use debugging information in a uniform way. It is proved that the method can uniformly manage debugging information of C language source file in DWARF and STABS form.
