整个系统将不得不更加复杂,并且会在运行时浪费宝贵的周期在许多(可能达到数万).text、.data 和其他段之间跳转。 所以,我们将要做的 instead is take each section of the object file and put it together with the same type of section from all other object files. 这个过程称为Relocatable对于对象文件). ...

[https://mp.weixin.qq.com/s/ydhK8HYuRD0lZazPsPxsvg] c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///...
struct Server { }; } } using namespace myapp; void addHTTPService(servers::Server const &server, ::services::WebService const *http) { server += http; } 对上面代码进行编译,Clang既提供了准确的信息,又保留了用户所写的类型(例如,"servers:::Server"、"::services:::WebService")。
对于自定义的类型(class 和 struct)是否能在python中被引用。 关于函数调用约定,有必要简单的提一下: Calling Convention和具体的编程语言无关,是由编译器、连接器和操作系统平台这些因素共同决定的。 The Visual C++ compilers allow you to specify conventions for passing arguments and return values between functi...
