A general description of C preprocessing is in section A12 of K&R. The C/C++ compiler includes standard C/C++ preprocessing functions, which are built into the first pass of the compiler. The preprocessor handles: Macro definitions and expansions #include files Conditional compilation Various ...
传统的编译器通常分为三个部分,前端(frontEnd),优化器(Optimizer)和后端(backEnd). 在编译过程中,前端主要负责词法和语法分析,将源代码转化为抽象语法树;优化器则是在前端的基础上,对得到的中间代码进行优化,使代码更加高效;后端则是将已经优化的中间代码转化为针对各自平台的机器代码。
The basic initialization function is Py_Initialize(). This initializes the table of loaded modules, and creates the fundamental modules __builtin__, __main__, sys, and exceptions. It also initializes the module search path (sys.path). ...
