Dear Renato and Anton,

Big thanks to your help. Those references are very helpful!

After I applying this patch from Logan Chien, I pass some examples on ARM
assembly emission. It seems good to me.
For object file emission, The first thing is making MC generate correct
.ARM.exidx and .ARM.extab. I will keep tracing that.
