similar to: [LLVMdev] Removing legacy profiling code from LLVM

BTW, this will also remove the entire 'runtime' directory in the LLVM repository. Runtime libraries are now being developed in compiler-rt. That is where the GCDA profiling runtime already lives and any new instrumentation based profiling runtime would also likely live there. If the code in the existing runtime tree is needed to start building those, they can always be found in the VCS

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

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

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

We've been actively using it since at least 2.8. True, we haven't been vocal about it. While I can see

Hello Everyone, Before I get started I just want to sincerely apologise for not getting feedback on this earlier. I've had an extremely busy week as I was presenting a paper at the CGO conference. If anyone is able to provide feedback in such a short time-frame then it will be gratefully received. If not, then I just hope the work described sounds useful. I have already submitted

Hi guys, I am trying to perform edge profiling using on hello.bc file by using following command opt -insert-edge-profiling hello.bc -o hello-edge.bc but I get the error that option "-insert-edge-profiling" is unknown. Can you please help me to solve the issue. Please note that I am following the paper available at this link http://llvm.org/pubs/2010-12-Preuss-PathProfiling.pdf

Hi Nick Thanks for you reply. CMAKE is very new to me. I complied using GNU WIN32 and got those errors. Is it possible to compile it using GNU WIN 32 and anything need to be modified? I managed to compile the run time library on a mac machine. Yafan On Fri, Apr 22, 2011 at 5:04 PM, Nick Lewycky <nicholas at mxc.ca> wrote: > yafan zhao wrote: > >> Hi All >> Thanks for

Hi all, as proposed in http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-February/020396.html I implemented the algorithm presented in [Ball94]. It only instruments the minimal number of edges necessary for edge profiling. The main changes introduced by this patch are: *) a interface compatible rewrite of ProfileInfo *) a cleanup of ProfileInfoLoader (some functionality in ProfileInfoLoader

This proposal adds support for path profiling [Ball96] to LLVM. Path profiling compactly represents acyclic paths in a directed acyclic graph representation of the control flow graph of a routine. Instrumentation can be added to uniquely identify paths executed at runtime. Path profiles enable precise enumeration of the sequence of basic blocks executed in order for a particular path. Using path

I'm trying to validate some changes to send to trunk and I'm getting a bunch of test failures like this: Error opening '/ptmp/dag/build/llvm/staging/debug/Debug+Asserts/lib/libprofile_rt.so': /ptmp/dag/build/llvm/staging/debug/Debug+Asserts/lib/libprofile_rt.so: cannot open shared object file: No such file or directory Indeed there is no libprofile_rt.so.

I want to get path profiling information with LLVM. LLVM provides methods for path profiling.I also get the llvmprof.out successfully. So I want to output the result.With llvm-prof ,I get the error:llvm-prof: Unkknown packet #5. So I have to write my own pass to output the path profiling result,the following is my kernel codes:

Hi, I have a problem with the following scenario: I use the ProfileEstimatorPass to get ProfileInfo and verifiy this info with the ProfileVerifierPass. (Please bear with me, its not about the profiling but about the Pass interaction.) Then the LowerSetJumpPass is executed and I want to verify that the esimtated ProfileInfo survives this pass by calling again the ProfileVerifierPass. This is what
