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.

入口点依次可以通过(在反汇编阶段)鉴定CALL指令来标识。

The entry points in turn could be identified by identifying the CALL instructions (in the disassembly stage).

路径是程序从入口到退出的指令顺序。

A path is an instruction sequence that threads through the program from entry to final exit.
