machine instruction register的意思|示意

An attempt was made to execute a floating point instruction when the floating point available bit in the MSR (machine status register) was disabled.

如果在MSR(机器状态寄存器)中可用的浮点位被禁用，将尝试执行一个浮点指令。

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。
