The first instruction does the load and the second instruction rotates the value so that the requested address is at the beginning of the register. 第一个指令负责加载,第二个指令旋转此值以便所请求的地址位于寄存器的开始。
Hbr hint_trigger,$ register& This tells the processor that the branch instruction at the relative address hint_trigger is likely to branch to the address specified in register$ register. hbrhinttrigger,$register&告诉处理器相对地址hinttrigger处的分支指令可能会跳转到寄存器$register所指定的地址。
Important registers to look for when debugging through signals are the GPRs, instruction pointer ( NIP), machine state register ( MSR), trap, data address register ( DAR), and so on. 在调试信号时,需要查看的一些重要寄存器包括GPR、指令指针(NIP)、机器状态寄存器(MSR)、Trap、数据地址寄存器(DAR)等等。
