...veral tests, each with a different optimization. The benchmark is all the 11 C programs in CINT2000 of SPEC. In all the tests, I found very little performance difference between Andersen and Steensgaard. Here is an example of the options in one of the tests: llvmc -opt -Wo,=-O3 -Wo,=-load=path_of_libLLVMDataStructure.so -Wo,=-steens-aa llvmc -opt -Wo,=-O3 -Wo,=-anders-aa the other optimizations are: dead code elimination, dead store elimination, const propogation, O1, etc. And now what confusing me are: 1 Did the optimizations really use the result of Andersen or Steensgaard? 2 It seems both Andersen and St...

...poolalloc shared object file to be the <path to pool allocator>, cause > no binary file has been generated. > Could you give me some suggestion? Thank you. There are two problems: 1) You need to load the library containing DSA first. To do that, you need to use the -load <path>/libLLVMDataStructure.so option. 2) I believe you are loading the wrong library. You want to load libpoolalloc.so and not libpoolalloc_rt.so. The former is the LLVM poolalloc transform pass; the latter is the run-time library implementing the poolallocation functions. If you're only interested in DSA (for points-...

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

The -analyze option is an option to opt to tell it to print analysis results instead of doing transformations. You still need to specify the analysis passes that you want run. For example, to see the local DSA results, do the followi...

Poolalloc build is also broken right now, but it works enough to be used with llvm-tv (you only need libLLVMDataStructure).

Thanks a lot for the reply guys. So, does that mean that I cant write my own passes if I work on Windows side of the LLVM? Is there any other way to use a new pass. How are windows users supposed to work? Thanks again.
