[llvm-dev] where does jump table stores?

[慕冬亮 via llvm-dev]

I got the following message from one paper called readactor:
> We found that the LLVM compiler only emits data in the

I am curious about why llvm puts this jump table(extrances of cases
for switch). I did the same test for gcc, I found gcc stores it in
rodata. I think rodata section is a good place for those structures to
stay.
If there is any misunderstanding, please inform me.
Thanks.
