similar to: [LLVMdev] Question about using steensgaard's pointer analysis in poolalloc

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

Hi, On Linux I observed [root at localhost poolalloc]# find . -name *.a ./Release+Asserts/lib/LLVMDataStructure.a ./Release+Asserts/lib/poolalloc.a ./Release+Asserts/lib/AssistDS.a ./Release+Asserts/lib/libpoolalloc_fl_rt.a ./Release+Asserts/lib/libpoolalloc_rt.a ./Release+Asserts/lib/libpa_pre_rt.a ./Release+Asserts/lib/libcount.a On cygwin I observed kpawar at KPAWAR-LT

Hi John, That worked for me. I am using llvm 3.2 only and following http://safecode.cs.illinois.edu/docs/Install.html So for I am able to make inside llvm/projects/poolalloc by doing such cosmetic changes. Now, when I tried to make inside llvm/projects/safecode, I see another error. kpawar at KPAWAR-LT ~/SAFECode/LLVM_SRC/llvm/projects/safecode $ /usr/bin/clang -cc1 -triple

The patch below adds dsa and some of poolalloc to opt. It should be simple enough to extend to all of poolalloc by adding more classes to LinkDSA.h.

Hi Daniel, To my knowledge, there is no other implementation available for Steensgaard AA except poolalloc. I have tried Steensgaard AA under LLVM 2.7 poolalloc, but there are lots of bugs which need to be fixed. It will be a good idea to use previous implementation, but you will have to modify (a lot) it with respect to the latest version of LLVM poolalloc. Thanks, -Yogesh -------------- next

Thanks John, for the update to the Makefiles. I did an "svn update" and am now able to build all the libraries. There were some problems building the poolalloc runtime but I'm not really interested in that. Andrew, thanks for the patch. I am trying to add DSA to opt as you suggested. What should the contents of LinkDSA.h be ? I would appreciate it if you could send me a copy of

Dear Patrick and Antron, I've modified the Makefiles in the poolalloc module so that they do not build shared libraries on MingW or Cygwin. Patrick, if you do an "svn up" you should be able to compile the poolalloc project now. -- John T.

Hi, I am trying to use the poolallocator. More specific, I am trying to play around with the pointer compression pass. Though, I get assertion failures for the pass dependencies. This is when it in PointerCompress::getAnalysisUsage tries to register the the BU pass as required. I.e. when AU.addRequired<CompleteBUDataStructures>(); is called. $ opt -f -load

Hi , This Is 'Suresh M' from AMD compiler team. 1) I obtained the source code of llvm and pool-alloc (relase_32 versions ) using the following commands, svn co http://llvm.org/svn/llvm-project/llvm/branches/release_32 llvm cd llvm/projects svn co http://llvm.org/svn/llvm-project/poolalloc/branches/release_32 poolalloc 2) Was able to build the binaries and libraries

Hi all, I too am getting this error for x86_64 when I am trying to use the Data Structure Analysis ...I svn upped both the llvm main branch and the poolalloc today in the morning and recompiled everything from scratch : $ opt -load /home/pprabhu/llvm/llvm-install-x86-64/lib/libpoolalloc.so -ds-aa < o.bc opt: /home/pprabhu/llvm/llvm/lib/VMCore/PassManager.cpp:1418: virtual void

Thanks for the answer I am trying to test the PA with a program very similar to the one used as an example in the paper located here: http://llvm.cs.uiuc.edu/pubs/2003-04-29-DataStructureAnalysisTR.html The program is as follows: ========================== struct list { struct list *Next; }; struct list *makeList (int Num) { struct list *New = malloc ( sizeof ( struct list ) );

Dear Prakash, I believe I've fixed the problem you were having with ds-aa. Please update your poolalloc tree, recompile, and let me know if it works. -- John T.

Ah, sorry, my memory was wrong. The default is to perform the

Thanks Chris! That was causing me some confusion. Now it's producing a more meaningful output: poolinit((&l2_GlobalPool), 4u, 4u); poolinit((&l2_GlobalPool1), 4u, 4u); l5_tmp_2E_0_2E_i = poolalloc((&l2_GlobalPool), 4u); l6_tmp_2E_7_2E_i2 = l1_makeList((&l2_GlobalPool1), 0); *(&((struct l_struct_2E_list *)l5_tmp_2E_0_2E_i)->field0) = l6_tmp_2E_7_2E_i2;

Hi, This is Jiesheng Wei from UBC. Now I am working on a project with LLVM and I want to use steensgaard alias analysis tool. I saw on the website that steensgaard analysis is available for LLVM 2.9 and it is under poolalloc/ directory. I downloaded several versions but none of them is compatible with LLVM 2.9. Can you please tell me which version of poolalloc is for LLVM 2.9? Thanks, Jiesheng
