[LLVMdev] Where are those complex aliase analysis passes like steens-aa now?

[Vikram S. Adve]

The ds-aa and steens-aa passes are all available in the llvm- 
poolalloc project, in lib/DSA.  They were moved there because  
Microsoft holds a patent on parts of the underlying pointer analysis  
strategy.  anders-aa is still in mainline llvm.
