在加载更多的程序集并转化IL为机器指令时，CLR的加载器有一点额外的工作要完成，那就是调整函数入口地址。

The CLR loader has a little more work to do to load many assemblies and turn IL into machine instructions, particularly resolving function addresses.

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。

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.

您有很多选择，但是为了简便起见，可以将这个地址简单地写入一个文件，要注意哪个地址是函数的入口地址，哪个地址是函数的出口地址(参见清单2)。

You have many options, but for the sake of simplicity, just write the addresses to a file, noting which addresses are function entry and which are exit (see Listing 2).
