similar to: [LLVMdev] DSA or rDSA ?

I seem to recall replying to this, but my email client says I didn't, so I'm responding again. :) The rDSA code is some experimental

Hi Criswell, Thanks for the reply. I am looking for a pass for the intra-procedural alias analyzing, as i am working on multithreaded debugging and looking for a way to pick up instructions from different threads accessing the same global variable, and is Steensguard workable for this scenario? or any other suggestions? I also find that the "rDSA" folder is not included in the Makefile,

Deal all, Recently i am searching for a intra-procedure alias analysis pass and the -ds-aa pass seems to be the one i am looking for. However, i find this post described that the rDSA code in PoorAlloc project was abandoned before ... https://groups.google.com/d/topic/llvm-dev/FMLmIh9Nz84/discussion But some other guys were interested in it and John Criswell also made a request in bug database on

@John: Since rDSA hasn't been used in ages, perhaps it's time we deleted it from the repository? It'll live on in SVN glory forever for interested parties, and will avoid some of the confusion about its purpose. Additionally, we probably shouldn't have entire directories of dead code in mainline O:). Given these reasons: mind if I remove it from trunk? ~Will On Sun, Jun 15,

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,

Thanks Everyone for the info. I am planning to work with DSA on llvm-2.9. Hope it is working as John mentioned.

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 -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, Richard, Your decompose vector patch works perfect on my site. Unfortunately, I still get stupid code because llvm '-dse' fails followed by 'decompose-vector' . I read the DSE code and it is definitely capable of eliminating unused memory stores if its AA works. I don't think basic AA works for me. I found my program have complex memory accesses, such as bi-dimentional

The README at the location shared by John says "DSA is undergoing significant changes and may not be entirely stable or correct. See lib/DSA/README" So, I was wondering from where should one pick the code. Although I will start my analysis and see how results turn out to be. But any comments on this line will be helpful. Thanks Manish On Tue, Sep 20, 2011 at 5:13 PM, Manish Gupta

I have a few questions on using dsa now that it has been moved out of llvm. I have llvm -r release_19 checked out from cvs, and llvm-poolalloc -r release_19 checked out from cvs into the projects directory, as John Criswell previously suggested. 1) I have some compiler transforms that I'm writing that use DSA. They can no longer find the header files for DSA. My transforms are located

Dear All, We'd like to move the Data Structure Analysis (DSA) code from the LLVM source tree (lib/Analysis/DataStructure) into the Pool Allocation project. I plan on starting this move next week Tuesday. If this change somehow affects you and you need me to wait, please email me and let me know. Otherwise, I assume Tuesday is good. -- John T.

I apologize if this has been answered previously, but why is DSA being removed from LLVM? I ask because I am currently using the latest CVS versions of LLVM and DSA.

Hi all, is there any plan when poolalloc and DSA will be adapted to compile and run with LLVM 2.7? I'm currently about to start a bigger project using DSA and it would be nice if I could use LLVM 2.7 instead of porting everything I do now from 2.6 to 2.7 later.

I updated dsa to mainline cvs. Poolalloc is broken, however. On Mar 6, 2007, at 3:39 AM, Ryan M.
