llvm dev - Jul 2013 - [LLVMdev] CallGraph in immutable pass

Hello,
is there any way I can access CallGraph from immutable pass via 
getAnalysis?
As I understand it, this may not be possible, because immutable pass 
don't have runOn method and is never actually planned. But I'm not 100% 
sure how this works, so I don't know if there is some other way.
Thanks,
Robert Barucak

Your understanding is correct -- this is impossible. What are you really
trying to do?

I'm working on implementation of some fancier alias analysis algorithm. 
I have experienced strange behavior when I registered my AA (as module 
pass) into AA group. Somehow I was unable to get correct DataLayout from 
AA interface. So I wanted to try to make it immutable, just like other 
AA implementations.
Anyway, thanks for clarification.
