Hi Chen Applied your patch to cmakelists files in LLVM 2.9 release and build llvm using Visual Studio 2008 successfully, but there is still no profile_rt.so. I do have profile_rt of visual studio solution file and project file in folder \llvm-2.9build\runtime\libprofile. I also tried version2.9 form SVN and it has all necessary cmakelists files now, but I still have same problem (no profile_rt.so). Did I miss any step? Where is your profile_rt.so...

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

Hey all, I want to run the profile.pl file in the utils folder but I am having trouble running the script because the profile_rt.so file is not generated properly.

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.

Hi again, I'm trying to upgrade my LLVM bindings in Java from 2.9 to 3.1. To do so, I regenerated the JNI bindings from fresh LLVM 3.1 headers, and did a slight rewrite of my CMakeLists.txt file for building the C code. Problem is, cmake no longer finishes at all. I receive the following output, and then it just runs forever (while still responding to a CTRL-C): > eli at

But this library isn't build if I use llvm-gcc 4 for the frontend. My question: Which library do I have to load instead of profile_rt.so?

...g. I had to explicitly build the runtime using 'make -C runtime install'. You will also find the utils/profile.pl script useful, which passes profiling options to opt for instrumenting the bytecode and calls lli with the correct arguments and paths for loading the profiling library profile_rt.so (which defines 'llvm_start_block_profiling' etc.) Best regards, Christian

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

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 -o output.bc" and an output file generates correctly. I have disassembled the output file and i can see that profiling code has been...
