帧函数可以动态分配堆栈空间并采用帧指针。
A frame function can dynamically allocate stack space and can employ a frame pointer.
这确保了帧指针寄存器将被用作帧指针，从而产生正确的回溯。
This ensures that the frame pointer register will be used as a frame pointer leading to accurate tracebacks.
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。
This will lead to better stack tracebacks, as the frame pointer register is used as a frame pointer rather than a general purpose register.
