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

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

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

Hi, I am curious about if the current LLVM implementation can handle Linux kernel (or any particular version of Linux kernel). The first question I have is that, how to create LLVM bytecode of Linux kernel using LLVM gcc frontend. What changes should I make to the compiling process Linux kernel? Secondly, is it possible to compile the assembly code in Linux kernel into LLVM bytecode? I noticed

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

Hi, I am having problem of using LLVM on a program which contains customized code section. In addition to ".text" section for keeping code, the program has another code section, called ".init.text". The functions in this section are defined as "int foo (int, int) __attribute__ ((section (".init.text")));" If I compile the program with gcc, this

Hi, all I just downloaded the latest version of llvm. I am interested in the data structure analysis of llvm described in this year PLDI paper, titled "Making Context-Sensitive Points-to Analysis with Heap Cloning Practical For The Real World". However, I could not find any source code that seem to do the analysis. I noticed that in llvm 1.9 release, there is a subdirectory named

Hi, all I have a question about how to profile program with LLVM. When I tried to compile the instrumented version of program after using "-insert-block-profiling", I got error complaining " undefined reference to `llvm_start_block_profiling'. I found that there is a "runtime"directory in llvm source directory but in the Makefile, it said llvm gcc 4 and above

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".
