search for: rdsa

@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:...

...r 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, and this means the -dsa-aa pass is still not reliable and probably i cannot use it, right? Thanks, Dan.

Dear All, I am trying to use DataStructure Alias Analysis. From the code at poolalloc it seems that rDSA needs to be compiled to get -ds-aa feature while the Makefile builds just the DSA. Please correct me if I am doing something wrong. Thanks, Manish -------------- next part -------------- An HTML attachment was scrubbed...

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 code that we abandoned. We removed the -ds-aa pass in mainline p...

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 this topic.

...s 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

Yes, ds-aa and -steens-aa were removed from poolalloc because we thought no one was using them, because we at Illinois weren't using them, and because...

Sorry, I don't really know this part of llvm, so I'm not sure what to suggest. Hopefully someone else will comment. Thanks, Richard

Hi, Richard, I think we are solving a same problem. I am working on shader language too. I am not satisfied with current binaries because vector operations are kept in llvm opt. glsl shader language has an operation called "swizzle". It can select sub-components of a vector. If a shader only takes components "xy" for a vec4. it's certainly wasteful to generate 4
