I'm trying to use steens-aa from poolalloc on llvm-2.6. However, when I run the alias analysis, steens aa falls back on default aa because the DSNodes are incomplete. My program is very simple. The default aa identifies that &a and &c.b cannot alias but d can alias with both of them. I use the AliasAnalysis.alias...

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

hi, The llvm alias analysis doc mentioned that llvm have various alias analysis passes, e.g. steens-aa; but I can't find it in llvm 2.0. Are these passes obsoleted?

Hi, I just found -steens-aa and -ds-aa Alias Analysis listed in documents do not exist in my llvm-2.3 code. Both from opt -help and the lib/Analysis. And then I go to download the llvm-2.5 version, there is still no these 2 options. Where are they? Lei -- /****** * Lei Shang * PhD candidate, Computer Science & Engi...

Are > these passes obsoleted? Thanks. I think that Steensgaard was part of the data structure analysis which has been moved out of llvm. We currently have -basicaa, -globalsmodref-aa, and anders-aa. The latter two are in the lib/Analysis/IPA directory....

Hi Chris, I took a haste look at the "Points-to Analysis in Almost Linear Time" by Steens , your PHD thesis and SteensGaard.cpp in LLVM this afternoon. So I think: 1. Actually the basic algorithm described originally by SteensGaard does not provide MOD/REF information for functions. 2. The context insensitive part of Data Structure Analysis (LocalAnalysis) can be deemed as an enhance...

Hi. I've done a standard barplotexample using R1-8.0, redhat8, probably using a GhostScript-integration. How can I improve the "sharpness" of the fonts. See for example the barplot (originally jpg coming from R) which is part of this screendump: http://www.zug.dk/Members/Nielssteenkrogh/1067525916309553166/element_103003161029 I'm not sure where to improve the this. Is it an R-issue or an GhostScript-issue or? /Niels Cand. Polit. Niels Steen Krogh Solsortvej 44 2000 F.

...ork in my GSoC final report. I think it is fantastic that you have done such an interesting work. I'll definitely try to help getting the code reviewed and merged in the current. After a quick glance at your patch, it seems that what you are trying to do there is an optimized version of CFL-Steens, with a custom way of handling context-sensitivity. I'll be happy if we can end up integrating it into the existing CFL-Steens pass. Regarding the benchmark numbers, I'm very interested in what kind of tests files were you running the experiments on? Is it possible to share it? > O...
