Hi All Thanks for all replies regarding to my GCC problem. I am trying to do profiling now and need to generate "profile_rt.so" file. I compiled the runtime library using MAKE and tried on both Windows and Mac, but the compiling can not be done properly. I got the following error message: ------------------------------ make: Entering directory `C:/llvm/runtime'

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'm newer in llvm i would like to instrument a byte code with a pass and as a result i would like to get an instrumented byte code. i would like that a pass add a method (which calculate the number of instructions) in the end of each block. the instrumented code should contain in each block a method that calculate the number of instructions Please Help me thank you -- Nabila ABDESSAIED

I can say that it does not for me,running x86_64, I have been generating errors for submission by testing on a number of gnu utilities starting with binutils.

How can I do function profiling and BB profiling with current llvm and llvm-gcc4? runtime/libprofile is disabled when using llvm-gcc4, but... is there any alternative to linking with libprofile_rt.so? How can I use llvm-prof? is utils/profile.pl obsolete? Thanks in advance, josem

Hello, My name is Rantao Chen and i am a student at the University of Maryland. I am currently doing some research for a professor to do Basic Block profiling using LLVM. I have set up the environment correctly and built the profile_rt.so shared library, but i am having some problems using the LLVM profiling tools. I run "opt -insert-function-profiling -insert-block-profiling input.bc

Hi, sorry but I can't found where the profiling data (llvmprof.out[?]) is generated. Perhaps soembody has a hint for me? Thank you very much Nico

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, Zhao > I have checked out llvm 2.9. There is only one CMakeLists file in Release or svn? I believe Nick has committed those CMake files into svn. You can apply my patch to LVM 2.9 Release. > "\llvm-2.9". and no CMakeLists file in folder either > "\llvm-2.9\runtime\libprofile" or "\llvm-2.9\runtime". Where did you get it? As Nick said, libprofile

I just read that LLVM project could be used to do static analysis on C/C++ codes using the analyzer Clang which the front end of LLVM. I wanted to know if it is possible to extract all the accesses to memory(variables, local as well as global) in the source code using LLVM. Is there any inbuilt library present in LLVM which I could use to extract this information. If not please suggest me how to
