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 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

Hi LLVM dev team: I am now doing an experiment to comparing Steensgaard-style and Andersen-style pointer analysis on LLVM. Since steensgaard pointer analysis is in module "poolalloc", so I installed poolalloc release 2.6 on my machine(intel X86_64 RedHatEnterpriseLinux 5.1, gcc-4.2.4), two directories "include" and "lib" were created after installation but no

Thanks for the reply. Would you happen to know whether there a global alias analysis written for LLVM that is more robust? Is the Steensgaard pass any more reliable?

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?

Thanks John. I appreciate your help and I look forward to obtaining the code. A proper LLVM sub-project: No rush on this and please take your time.

Hi Xin, Thank you for your reply! I have tried the 3 alias analyses you have mentioned on LLVM 3.5: 1) $ opt -globalsmodref-aa -aa-eval < xxx.bc > /dev/null (May-alias response 100%) 2) $ opt -tbaa -aa-eval < xxx.bc > /dev/null (May-alias response 100%) 3) $ opt -cfl-aa -aa-eval < xxx.bc> /dev/null (Unknown command line argument '-cfl-aa') It seems that they are not

Thanks Everyone for the info. I am planning to work with DSA on llvm-2.9. Hope it is working as John mentioned.

Thanks John for the super quick checkin. I was a little surprised here. Yesterday/today I spent some time trying to build poolalloc on my mac dev machine. Unfortunately, it failed to build [1]. Looks like the compiler can't find the header files under /usr/include/c++. I also tried to build on my linux box and saw the same problem. giri built successfully. Are you sure poolalloc builds on

The README at the location shared by John says "DSA is undergoing significant changes and may not be entirely stable or correct. See lib/DSA/README" So, I was wondering from where should one pick the code. Although I will start my analysis and see how results turn out to be. But any comments on this line will be helpful.

Thanks. Okay, I've created a new LLVM sub-project called Giri(*). It currently contains only the static backwards slicing pass. I'll add the dynamic slicing code to the project later.

Hi all, is there any plan when poolalloc and DSA will be adapted to compile and run with LLVM 2.7? I'm currently about to start a bigger project using DSA and it would be nice if I could use LLVM 2.7 instead of porting everything I do now from 2.6 to 2.7 later.
