QEMU中log⽇志⽂件的使⽤在启动时加 -d命令，参考如下：
exotic./qemu-system-ppc -hdc ../../mirror/debian_squeeze_powerpc_desktop.qcow2\
-M mac99\
-monitor stdio\study abroad
-d out_asm\
若要打印多个选项可采⽤如下⽅式（即中间加逗号即可）lead
./qemu-system-ppc -hdc ../../../mirror/debian_squeeze_powerpc_desktop.qcow2\
-M mac99\
-monitor stdio\
-d in_asm,op\
识别英文
log选项如下：（在qemu-3.1.0-rc0\util\log.c中定义）
Log items (comma parated):
out_asm show generated host asmbly code for each compiled TB小语种有哪些

op show micro ops for each compiled TB
韩语培训班op_opt show micro ops after optimization
op_ind show micro ops before indirect lowering
blou什么意思int show interrupts/exceptions in short format
