Static函数没有this指针,可以认为他就是普通的c函数。 普通的c函数编译器都是通过name mangling技术,来对函数加以区分: StackObj->instance()等同于:ZN1A8instanceEv() 备注: ①事实上编译器为了避免函数重载造成的重名情况,会对函数的名字进行处理,使之成为独一无二的名称。 (name mangling技术) ②将成员函数声...
常见编译特性: c++ name mangling 示例 #include<iostream>voidfoo(){// 符号名称为:_Z3foovstd::cout<<"foo"<<std::endl;}voidfoo(intc){// 符号名称为 _Z3fooistd::cout<<"foo"<<c<<std::endl;}intmain(){std::cout<<"zms"<<std::endl;foo();foo(2);return0;}// g++ hello.cc -o...
Enter your mangled GCC or MSVC C++ symbols and we will return them unmangled and readable! One step. Nothing to install.
