编译原理的源代码，涉及了编译原理的各个过程：词法分析，LL1语法分析，语义分析，中间代码生成，中间代码优化（常表达式优化，公共表达式优化，循环不变式优化），中间...

词法分析程序设计 1、给出各单词符号的类别编码。 2、词法分析程序应能发现输入串中的错误。 3、词法分析作为单独一遍编写，词法分析结果为二元式序列组成的-Lexical analysis program design one, given the various types of code word symbols. 2, lexical analysis procedure should be able to detect errors in the input strings. 3, again as a separate lexical analysis prepared for morphological analysis of binary sequence composed of

一款编译器，针对vb，英文版。本程序包括详细的词法分析，语法分析，语义分析和中间代码生成，写得很不错，可读性很强。是关于循环语句的翻译-new compiler, against vb and English. The procedures include detailed lexical analysis, grammar analysis, semantic analysis and intermediate code generation, very good, very readable. On the loop is the translation

一个很好的编译原理课程设计，要下来看看哦-Compilation Principle of a good curriculum design, it is necessary to look down Oh

(1)构造文法G的LR(0)项目 (2)构造文法G的LR(0)项目集规范族及识别活前缀的DFA (3)证明文法G不是LR(0)文法而是SLR(1)文法，并构造SLR(1)分析表 (4)设计LR语法分析程序，且能输出分析过程 (5)列举两个例子测试语法分析程序（识别失败一例，识别成功一例，后者推导步骤不得少于10步） -(1) construct grammar G of the LR (0) item (2) construct grammar G of the LR (0) item sets standards and identification of family living prefix DFA (3) prove that the grammar G is not LR (0) grammar, but the SLR (1 ) grammar, and constructs SLR (1) analysis table (4) design LR parser, and can output analysis process (5) cited two examples of parsing test procedures (identification fails an example, identify the success of a case, the latter shall not be derived step Less than 10 steps)

LL(1)语法分析器，在任何时候，总控程序都是按照栈顶符号X和当前输入符号a行事的。对于任何（X，a），总控程序每次都执行下述三种可能的动作之一： 若X＝a＝’＃’，则宣布分析成功，停止分析过程； 若X＝a≠’＃’，则把X从栈顶逐出，让a指向下一输入符号； 若X是一个非终结符，则查看分析表M。若M中存放着一条关于X的产生式，那么，首先把X逐出栈顶，然后，把产生式的右部符号按反序一一推进栈，同时做这个产生式相应的语义动作（目前不管）。若M[X，a]中存放着一条出错标志，则调用出错诊查程序Error。-LL (1) parser

语法分析器，对已给pascal语言文法，构造LL(1)分析表，编制语法分析程序，要求将错误信息输出到语法错误文件中，并输出分析句子的过程-Parser that have been to the pascal language grammar, structure LL (1) analysis table, the preparation of parsing procedure that requires the output to the error message syntax error file, and output analysis of the process of sentence

单独分离出来的C-手工词法分析器，需要自己建立一个工程来运行本程序。为《编译原理与实践》一书之后的实验题的代码。-Single isolated C-hand lexical analyzer, needs its own to establish a project to run this program. For " Compiler Construction Principles and Practice," a book after the experiment of the code.

编译原理词法分析，将源文件分类存入文件，供语法分析使用-Compiler Construction Principles lexical analysis, classification of documents into the source document for the use of grammatical analysis
