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。
This is especially important when asynchronous invocation is used where the calling task has to look for the output of the called task appearing at a particular location to continue further.
当使用了异步调用,而调用的任务需要查找所调用任务在特定位置生成的输出才能够继续后续操作时,这种方法是特别重要的。
It becomes the responsibility of the calling function to keep track of this memory location and handle it properly.
跟踪该内存位置并正确地处理它就成为了calling函数的职责。
