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,

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?

Does anyone have experience to compile Linux kernel in LLVM-2.6? I am working on a C/C++ race detection framework and want to test in large applications. But I do have a lot of errors while compiling Linux kernel 2.6.3 using LLVM-2.6. Actually, I only need to get the .bc bitcode file. Anyboy does similar work before? Which Linux kernel version is used and any skills? Thanks. Lei /****** * Lei

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 method to find out pairwise from within my own analysis which of the

HI guys. I'm trying to build the poolalloc on llvm-2.0 but there exist some errors. Can you tell me which version of llvm is known to make the poolalloc build and install successful?

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

Hi, LLVM dev team: Thanks for your suggestion, I have done the experiment to compare the two pointer analysis(Andersen and Steensgaard) methods in LLVM, but the result was unexpected. In each test, I compare these two methods using same optimization; There are several tests, each with a different optimization. The benchmark is all the 11 C programs in CINT2000 of SPEC. In all the tests, I found

I haven't played with this stuff for a long time,

Hi, I'm looking for interprocedural AAs and have, of course, found https://llvm.org/docs/AliasAnalysis.html. However, the AAs that come bundled with LLVM do not work interprocedurally in a way that I need it (on/with stack variables). The two interesting looking AAs come with the optional `poolalloc' module that hasn't been updated in years (I guess

Hi David, I am the one who's responsible for CFLAA's refactoring in the summer. I've sent out another email on llvm-dev, and you can find more about my work 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

Dear Staff, Here are some questions on the output formats of AliasSetTracker. The code is as below: int G1 = 9; int G2 = 5; int main() { int * XX; int * YY; XX = &G1; YY = XX; YY = &G2; XX = &G2; } The output for -anders-aa is: Alias Set Tracker: 5 alias sets for 4 pointer values. AliasSet[0xea6fb0,0] may alias, Mod/Ref 10 Call Sites: void ({ }*)*
