This simple design, possible because the data obeys strict LIFO order, means that no complex data structure is needed to track stack contents - a simple pointer to the top of the stack will do.
这种简单的设计,很有可能是考虑到数据操作都符合后进先出(LIFO )规则,这意味着访问栈的内容并不需要复杂的数据结构,一个简单的栈顶指针就能搞定一切。
This simple design, possible because the data obeys strict LIFO order, means that no complex data structure is needed to track stack contents – a simple pointer to the top of the stack will do.
这个简单的设计,可能是因为数据遵循严格的 后进先出顺序,这意味着没有复杂的数据结构需要跟踪堆栈的内容-一个简单的指针的堆栈的顶部就可以了。
For example, a (trivial) new command called hari could be defined that would display one line of memory starting at address 0xc000000, display the contents of the registers, and dump the stack.
例如,可以定义一个(简单的)新命令hari,它显示从地址0xc000000开始的一行内存、显示寄存器的内容并转储堆栈。
