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?

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, 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, 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

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

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

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... URL:

@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'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

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 John, thanks for your feedback. I'll try to answer your comments bellow.
