if the config_frame_pointer option was set during kernel compilation, the frame pointer register is used to maintain stacks and, hence, the stack traceback can be performed correctly.
如果内核编译期间设置了 config_frame_pointer选项,那么就用帧指针寄存器来维护堆栈,从而就可以正确地执行堆栈回溯。
this will lead to better stack tracebacks, as the frame pointer register is used as a frame pointer rather than a general purpose register.
这将产生更好的堆栈回溯,因为帧指针寄存器被用作帧指针而不是通用寄存器。
it essentially created a singly linked list that linked the frame pointer for each of the callers to a function.
它实质上创建了一个单链表以链接为每个函数调用的帧指针。
