similar to: [LLVMdev] Profile Test Failures

Hi David, You don't say which tests are failing, but they are probably ones I wrote (not many use libprofile_rt.so). On 08/01/13 11:18, dag at cray.com wrote: > I'm trying to validate some changes to send to trunk and I'm getting a > bunch of test failures like this: > > Error opening >

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

I wanted to use to use profile.pl to know the execution count of basic blocks. However, I was not successfull with the following error message. I am using the latest version from CVS repository. Could somebody help me out? Thanks. --- Error Message I got ------------------------ linux$ profile.pl -block ccc.bc Error opening '/home/myhome/llvm/llvm-install/bin/../../Debug/lib/libprofile_rt\

Hi, when I try to build libprofile with r80670 (both llvm and llvm-gcc) I get this error: make[1]: Entering directory `.../llvm-svn-debug-obj/runtime/libprofile' llvm[1]: Building Debug Bytecode Archive libprofile_rt.bca (internalize) llvm[1]: Installing Debug Shared Library /nfs/a5/astifter/astifter/llvm/llvm-svn-debug-obj/../llvm-svn-debug-install/lib/libprofile_rt.so 0 llvm-ld

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

Dear all, I have already checked some related posted messages, such as: http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-January/012315.html and http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-February/012466.html After getting rid of some error messages, I was able to run the following commands: 1) opt -insert-path-profiling matmul.bc -o matmul.pp.bc 2) lli -load

What version of LLVM are you using? The profiling framework is completely messed up in the newer versions of LLVM.. I used to work with profiling in 2.5 some time ago, and it seemed to work fine.. If you really need this to work quickly, you might want to just get the old version and get on with it.. The newer versions of LLVM need to get the profiling part fixed soon..It is messing up my work as

Thank you for your suggestions on the patch. If the patch is committed, I would be willing to maintain it, though I am not sure what is all involved or how I am made aware of changes that need to be made. The technical report https://www.cs.ualberta.ca/system/files/tech_report/2010/PreussPathProfLLVM.pdf contains my benchmarks relating to profiling overhead in LLVM. Over the next week I will

Hi all, In light of the expected removal of ProfileInfo this is a request for comments on the next few items that I now plan to work on for GSoC. Planned tasks: #0 Add support for determining branch weight metadata by profiling At the absolute minimum this will require writing a new profile loader which will set branch weight metadata based on profiling data. #1 Optionally use profiling

I am a student at the University of Alberta under the supervision of José Nelson Amaral, and I have been working on implementing path profiling into LLVM. I have completed my project and would like to submit it. We are looking for a reviewer for the path profiling implementation. We have sent previous requests to the llvmdev list but have so far been unsuccessful. Please see the attached

Hi, I am new to LLVM, and would like to write a dynamic profiler, say which prints out the load address of all the load instructions encountered in a program. >From what I could pick up, edge-profiler.cpp increments a counter dynamically which is somehow dumped onto llvmprof.out by profile.pl Could anyone explain me how this works? Can I instrument the code to dump out the load addresses or

Alright, I'm ready to nuke it. Last chance to say stop. For context of others, this has come up repeatedly: no one we know of is using EdgeProfiling.cpp, PathProfiling.cpp, and the lib/Analysis/Profile*Pass.cpp collection of tools. They haven't been updated since 2012 when Alastair Murray looked into this stuff, and both current efforts towards PGO are essentially *totally* different

Thank you Alexey. I have tried to use Makefile. This will generate the correct symbols that I need. Any idea on the schedule of adding CMake support to compiler-rt?

Hi All, I think Nick's suggestion is correct, my code was linked against libprofile_rt.a, which had gcda profiling code before, but was removed https://github.com/llvm-mirror/llvm/commit/218042a02305a3cc38d968a97ff9ecf4b4abe6ff So, I couldn't find the correct symbols from libprofile_rt.a any more. Now my assumption is I need to use the correct library that is provided by compiler-rt.

Thank you Alexey. I will try this out this week. Any idea on supporting this for Mac? My raw idea is to add this to compiler-rt/lib/profile/CMakeLists.txt if(APPLE) foreach(arch ${PROFILE_SUPPORTED_ARCH}) add_compiler_rt_static_runtime(clang_rt.profile-${arch} ${arch} SOURCES ${PROFILE_SOURCES} CFLAGS --sysroot=${COMPILER_RT_DARWIN_SDK_SYSROOT}) endforeach() endif() Do you
