Hello, I am planning on contributing path profiling to LLVM by the end of August. I have written a document of what the interface to the path profiles would look like at that time. If someone has any amendments, I can incorporate them. http://www.cs.ualberta.ca/~pejic/PathProfiling.html Slobodan Pejic

Dear LLVM Developers: I am an undergraduate summer research student supervised by José Nelson Amaral at the University of Alberta. My work will primarily involve value profiling and path profiling. Andreas Neustifter is planning some changes to the profiling related code in LLVM (http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-February/020396.html). Are any of these changes in yet? Which

Hi, I try to create a array that has a nonzero initialiser: What i do is, first create the array type. > const ArrayType *ATy = ArrayType::get(Type::Int32Ty, NumEdges); Then create some constant values for the initializer. > std::vector<Constant*> Initializer; Initializer.reserve(NumEdges); > APInt zero(32,0); Constant* zeroc = ConstantInt::get(zero); > APInt

Ball Larus path profiling requires temporarily changing the CFG by replacing backedges (such as those caused by loops) in order to determine instrumentation placement, and attaching increments to edges [Ball96]. As far as I understand the CFG available through the BasicBlock class directly corresponds to the IR. I would rather not change the IR except to insert the profiling code. So, is

Hi, The profiling library (lib/libprofile_rt.bca built with gmake from runtime/libprofile) generates an archive with a profile_rt.o file that is actually a shell script, a wrapper around lli. I found the error in Makefile.rules, but I do know where else this needs to change (CMake and such.) The change to Makefile.rules is attached. Thanks, -------------- next part -------------- A

Hi, I'm trying to get a feel for what the LLVM community wants to get out of path profiles. Ball Larus path profiles contain counters for path numbers, but this raw information is not too useful. Some potential queries follow: - Given a path number, and function give a basic block iterator over the path. - Given a function give path numbers ordered by counts. - Given a basic block give
