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 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

hi, all: i want to add a function in xen. in the function i need to call the "printk" to display the values of some variables. i found the definition of printk() in file "xen-3.1.0-src\xen\include\xen\lib.h ": extern void printk(const char *format, ...) __attribute__ ((format (printf, 1, 2))); who can tell me the location of printk()? thanks in advance. 2008-04-26

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

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

LLVM3.8 version. https://bugs.llvm.org//show_bug.cgi?id=24233. The example can catch exception. But I use my own code for testing, CustomEHMemoryManager allocated memory address is very large, allocateCodeSection, allocateDataSection assigned address (more than 32 bit address space) is getting smaller and smaller. Cause registerEHFrames to fail. 3.9.1 or 4.0.0 version has been supported on win

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

For help: Llvm generated instruction calls a function (extern), the function will have a SEH exception (EXCEPTION_ACCESS_VIOLATION), But JIT can not capture the exception of the EXCEPTION_ACCESS_VIOLATION. I saw Bug 24233. EXCEPTION_ACCESS_VIOLATION exception cannot be captured after modification. How to catch EXCEPTION_ACCESS_VIOLATION exceptions on win64 ? haifeng.qin at wellintech.com

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

This sounds as if you’re putting the alloca inside the loop, not in the entry basic block and reusing it. If you

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
