在寄存器加上一个常量是为了计算用于加载或存储的地址。
The constant gets added to the register to compute the address to use for loading or storing.
所以该指令会将链接寄存器(存有返回地址)存储到调用函数堆栈框架的恰当位置。
So this instruction stores the link register (which holds the return address) into the proper location in the calling function's stack frame.
使用其他模式无法进行的内存访问(地址可以通过其他方式进行计算，并存储到寄存器中，然后就使用这个值来访问内存)。
Any memory access that is not available by other modes (the address can be calculated by other means and stored in the register, which is then used for the access).
PPE用载入和存储指令访问主存储器(有效地址空间)，可以在主存储器与内容可以缓存的私有寄存器文件之间移动数据。
The PPE accesses main storage (the effective-address space) with load and store instructions that move data between main storage and a private register file, the contents of which may be cached.
地址总线被处理器用来选择在特定外设中的存储器地址或寄存器。
The address bus is used by the processor to select aspecific memory location or register within a particular peripheral.
