Each instruction on the PowerPC is exactly 32 bits long, with the instruction's opcode (the code telling the processor which instruction it is) taking the first six bits.
PowerPC上的每条指令都正好是32位长，指令的op code(操作符，告诉处理器这条指令是什么的代码)占据了前6位。
One way of debugging this failure is to do an object dump of the executable and save it in a file, then search for the failed instruction (in this case, the failed opcode is 98080000).
调试这个问题的一种方法是对这个可执行程序执行objdump命令，并将其结果保存到一个文件中；然后查找出错的指令(在本例中，出错的操作码是98080000)。
