[LLVMdev] Are ds-aa and steens-aa still in Poolalloc?
Hi, I was looking at the LLVM's alias analysis documentation (http://llvm.org/docs/AliasAnalysis.html#exist) and it seems that poolalloc has ds-aa and steens-aa. However, I followed the instructions to use these passes, but I wasn't able to use them. Also, I found this: http://old.nabble.com/DSA-or-rDSA---td32576486.html saying that they were removed from poolalloc. Is that true? If so, should I submit a patch to update the webpage? Douglas

I believe one of our students also said they had become buggy. A patch to update the web page would be nice; a patch to bring -ds-aa back to life would be even better. :) -- John T.> > > Douglas > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev

[LLVMdev] Are ds-aa and steens-aa still in Poolalloc?
Hi John, I'll take a look at the DSA implementation to see if I can understand the code and fix it. Meanwhile, here is a patch to update the web page.
