object pascal编译器源码-object pascal compiler source

现将本人搜集常用的程序设计语言的词法和形式文法提供给大家。其中，词法是按LEX格式编辑，形式文法是按YACC格式书写，大家可直接用LEX和YACC工具编译生成各类程序设计语言的分析器。-commonly used programming language syntax and grammar forms to the public. Among them, morphology is based on LEX format editing, grammar form is written by YACC format, we can use the LEX and YACC tools various compiler generation programming language analyzer.

语义分析的功能： 第一，审查每个语法结构的静态语义，即验证语法结构合法的程序是否真正有意义。有时把这个工作称为静态语义分析或静态审查。第二，如果静态语义正确，语义处理则要执行真正的翻译，即，或者将源程序翻译成程序的一种中间表示形式（中间代码），或者将源程序翻译成目标代码。 有报告-Semantic analysis of the functions: First, review each of the grammatical structure of the static semantics, that is, the grammatical structure to verify whether the procedures legally meaningful. Sometimes this is called static or static semantic analysis review. Secondly, if the correct static semantics, semantic processing should be the implementation of a genuine translation, that is, or will be translated into procedures source an intermediate representation (intermediate code), or source code translated into object code. There are reports
