The stack pointer tells you where the end of your current stack frame is.
堆栈指针给出的是当前堆栈框架的结束位置。
You could even just use a single pointer and write data back into the buffer you got it from, although this might be a nuisance to program for on the other end.
您甚至只需要使用一个指针并将数据写回到读取数据所使用的缓冲区中即可,不过这对于另外一端的编程来说可能有些麻烦。
You then use register 127 as your loop counter and register 126 as your base pointer, and perform convert_to_upper on each value until you get to the end of the buffer.
然后再将寄存器127用作循环计数器,将寄存器126用作基指针,并在每个值上执行convert _ to_upper,直到到达缓冲区的底部为止。
