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). ...

Catching an exception by value also requires the exception object to be copyable. The following code compiled in Visual Studio 2013, but doesn't compile in Visual Studio 2015: C++ Copy struct B { public: B(); private: B(const B &); }; struct D : public B {}; int main() { try...

在其他语种中例如JAVA,C++,Ruby等这些语言中new是很常见的,但是在object-c中,大家最常见到的和最常用的初始化方法就是[[ClassName alloc] init]而不是[ClassName new]去初始化对象。 先来看看他们的方法实现: + new { id newObject = (*_alloc)((Class)self, 0); ...
Release 0.6.2 (in development) is primarily a bug fix release, refer to CHANGELOG for details. A long standing bug has been fixed where where objects created before a call to _create_as_root would not be properly aligned, and buffer end is now also padded to largest object seen within ...
