(1)预处理(Preprocessing):GCC 调用预处理器使用参数-E会处理源代码中的预处理指令,包括宏展开 #define、文件包含 #include、条件编译 #ifdef、#ifndef、#if、#endif 等,得到的还是源文件,表示为test.i。 $ g++ -E test.c -o test.i (2)编译(Compilation):GCC 调用编译器使用参数-S将预处理后的代码转换...

编译过程的功能如下所示。 预处理:在预处理阶段,主要完成对源代码中的预编译语句(如宏定义define等)和 文件包含进行处理。需要完成的工作是对预编译指令进行替换,把包含文件放置到需 要编译的文件中。完成这些工作后,会生成一个非常完整的C程序源文件。 编译:gcc对预处理以后的文件进行编译,生成以.s为后缀的汇编...

C/C++源文件中,以“#”开头的命令被称为预处理命令,如包含命令“#include”、宏定义命令“#define”、条件编译命令“#if”、“#ifdef”等。预处理就是将要包含(include)的文件插入原文件中、将宏定义展开、根据条件编译命令选择要使用的代码,最后将这些代码输出到一个“.i”文件中等待进一步处理。

It works exactly the same, just squeeze what you would type after #pragma in a string literal. And if what you typed happened to be a string literal, then add escape sequences \". Example: #include <stdio.h> #define CHECK_ALL_THE_STUFF \ _Pragma ("GCC diagnostic push") \ _Pragma...
