So this instruction stores the link register (which holds the return address) into the proper location in the calling function's stack frame.

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。

BRSL stands for "branch relative and set link." This branches to the function entry point and sets the link register (LR) to the next instruction for the return address.

brsl代表“branch relative and set link”，用来分支到函数的入口点并将链接寄存器(LR)设置为返回地址的下一个指令。

The LK bit specifies whether the address of the next sequential instruction is saved in the Link Register as a return address for a subroutine call.

LK位指定了下一个顺序指令的地址是否作为子例程调用的返回地址保存在链接寄存器中。
