使用gcc -E main.c -o main.s定义的 pragma message 会被打印 接下来使用gcc -S main.i -o main.s也会被打印 编译 1.词法分析:分析关键字,标识符等的合法性 2.语法分析:检查,代码是否遵循 c 语音语法规范 3.语义分析:分析表达式是否合法 汇编器 ...
pragma message string Prints string as a compiler message on compilation. The message is informational only, and is neither a compilation warning nor an error. Newlines can be included in the string by using the ‘\n’ escape sequence.
