llvm dev - Sep 2011 - [LLVMdev] Alias Analysis (Andersen pointer analysis)

Dear All,

I am curious to know the reason for removal of andersen pointer analysis. Is
it because of some issues? We need it on llvm-2.9, if possible.

Do we have some better version of pointer analysis on llvm-2.9?

Thanks,
Manish

I think it was removed because it didn't work properly and no-one was trying
to
improve it.  There was an explanation in the release notes IIRC.

Ciao, Duncan.

The Data Structure Analysis pass (DSA) is a unification-style points-to 
analysis.  It should work with LLVM mainline and the upcoming 3.0 
release.  An older version works with LLVM 2.7.

DSA is located in the poolalloc project 
(https://llvm.org/svn/llvm-project/poolalloc/trunk).

Thanks Everyone for the info.

I am planning to work with DSA on llvm-2.9. Hope it is working as John
mentioned.
