Fenris是一个检测并把高层次的语言结构做成文档的多功能故障检测器、调试器、代码分析工具。它能回复符号，把程序执行流绘成图，检查内部运行情况，恢复符号表，并处理反调试保护。它有一个命令行接口和一个类似SoftICE的GUI与Web前端-Fenris is a detection and high-level language structure made of multifunctional document fault detection, debugging, code analysis tools. It can restore symbols, compose program execution flow map, check their internal operations, restoration of the symbol table, and to deal with anti-debugging protection. It is a command line interface and a similar SoftICE with the GUI front-end Web

一个非常有用的程序，c语言写得，对于很多学单片机的朋友或许有用。 -A very useful procedure, c language written, for many school friends SCM may be useful.

为了实现的编译程序实用，源程序可采用自由书写格式，即一行内可以书写多个语句，一个语句也可以占领多行书写；标识符的前20个字符有效；整数用2个字节表示；长整数用4个字节表示。这样词法分析程序的主要工作为： （1）从源程序文件中读入字符。 （2）统计行数和列数用于错误单词的定位。 （3）删除空格类字符，包括回车、制表符空格。 （4）按拼写单词，并用（种别，单词）二元式表示。 （5）根据需要是否填写标识符表供以后各阶段使用。 这里采用的编译程序的实现方法是一遍扫描，即从左到右只扫描一次源程序，也就是词法分析作为语法分析的一个子程序。故在编写词法分析程序时，用重复调用词法分析子程序取一单词的方法得到整个源程序的二元式流。 -in order to achieve the compiler practical, available free to write source code format, that his writing can be more than words, a statement can occupy multiple lines written; identifier of 20 characters effective; Integer with two byte; long integer with four byte. This lexical analysis for major work : (1) from source document read into the characters. (2) Statistics and a few mistakes out a few words for positioning. (3) delete the blank type characters, including the carriage return, tab spaces. (4) the spelling words and use (other species, words) dual ceremony. (5) whether the need for completing the table identifier subsequent stages. Here the compilers of th
