A following question about how to install "poolalloc". I checked out poolalloc from svn. But I had a problem of installing it. When I tried to run "configure" with options "--with-llvmsrc" and "--with--llvmobj" pointing to where the source of my llvm and objs dir are (/home/usr/Tools/llvm, e.g.), "configure" complained error message

okay. I guess I figured it out. It seems "poolalloc" needs to be put in llvm/projects/ directory.

Hi, I ran into a problem when running DSA on Linux kernel (the Kernel version I used is 2.4.31). The analysis was aborted when it tried to do DSNode::mergeTypeInfo on some data structure in the kernel. I have filed a bug report at http://llvm.org/bugs/show_bug.cgi?id=1656. My question is what version of Linux kernel LLVM has been tested on successfully? To run DSA analysis, should I use the

DSA should be current against head, but poolalloc isn't. I've changed DSA a bit so it may not compile with poolalloc as is. I haven't had time to tackle updating poolalloc (either to head or to the dsa changes). If you want the version from the paper, try checking out llvm 1.8 or 1.9 and a dsa from around then. The dsa as used on the linux kernel and in the OS work is in a branch

I updated the latest "poolalloc" code and the problem seems to have been fixed. However, I am still having problem of running "poolalloc". After compilation finished, there are several dynamic libraries created (libpoolalloc_rt.so, libpoolalloc_fl_rt.so and LLVMDataStructure.so). I was not sure which one I should use so I just tried all of them with "opt -load".

Dear all, I am trying to reproduce the "Percent May Alias" result described in PLDI 07's paper "Making Context-Sensitive Points-to Analysis with Heap Cloning Practical For The Real World" (http://llvm.org/pubs/2007-06-10-PLDI-DSA.html ). However, my "Percent May Alias" for all the benchmarks is much greater, especially "bzip2". The DSA code I use is

However, it seems the resulting shared library LLVMDataStructure.so (I haven't checked the others) has some undefined symbols. Trying to load it into the opt tool produces an error: undefined symbol:

Dear John, I intend to implement the improvements on DSA. After running DSA on SPEC, I found DSA gives low precision for mcf and bzip2. I have checked the most imprecise c files in mcf an found that the code seems to be a mixture of "PHI" and "GEP" instructions. Could you please give me some hints about what the big picture of the improvement should be and how to start? Thank

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, I have a question about memory page tables in Xen. As far as I understood, every modification to page table will go through Xen(hypervisor). Is it so that all page tables are actually allocated in Xen(hypervisor) instead of guest OS(domain)? Also, is it the case that Xen(hypervisor) needs to maintain a page table for each process running in every domain? Thanks Haifeng

I currently have a slightly modified llvm-2.0 source tree (from the release tarball). I checked out poolalloc into the projects directory and attempt to configure it, but I keep getting errors. I would understand if there were problems building it (since it may require a different version of llvm), but it should at least configure. Specifically, I've tried the following commands: >
