similar to: [LLVMdev] Path Profiling

Adam, Path profiling would be a useful addition to LLVM but that by itself is not enough to include it in mainline LLVM. There has to be someone willing to maintain it as well, including bug fixes and code updates as LLVM APIs change. Is that something you are willing to do? --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve

Summary: We need to find a reviewer for our implementation of Ball-Laurus path profiling. It is well known that path profiling generates more precise information about a program's behaviour than edge profiling. We are conducting a research project with the goal of developing a methodology to make feedback-directed optimization (FDO) more sound. We are developing combined profiles that enable

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, I use llvm version 2.9. llvm-prof does not support to read path profiling info. So could I use any way else to read path profiling info?

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

Dear LLVM developers: I am a summer research 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; please see the attached patch and associated documentation. Should I send the patch to the commit mailing list? Adam Preuss --------------

Hi members, I am a LLVM newbee. I am working in path profiling. I got an error message when reading the path profile data I made a sample source named foo.c The command chain to make llvm path profiling as follows: 1. Compile to LLVM Bitcode llvm-gcc –emit-llvm foo.c –c –o foo.bc 2. Insert Path Instruments opt –insert-path-profiling foo.bc –o foo_path.bc 3. Link with profile

Hello; I was trying to use utils/profile.pl script to get path profile and print it from a simple hello world program. First I do the following - Compile the hello.c into LLVM bitcode file using - clang hello.c -S -emit-llvm -o hello.bc But when I try to run the following script - ../llvmclang/llvm-3.0.src/utils/profile.pl -edge hello.bc I get the following error - llvm-prof: hello.bc:

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

Dear Members, I am working on path profiling, but command llvm-prof cannot read path profile info. Making llvm-prof to be able to read PP info is so wonderful. But I cannot find the format of PP. Could anyone give me the document of path profile info format so that I could modify llvm-prof. Thank you in advance Linh Ho -------------- next part -------------- An HTML attachment was

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

Hi, Here is a link to my document on PP. On page 4, it has the format of the path profile. http://lists.cs.uiuc.edu/pipermail/llvmdev/attachments/20100823/db8abfb3/attachment-0001.pdf Cheers, Adam On 2011-05-22, at 9:31 PM, Linh Ho Tran wrote: > Dear Members, > > I am working on path profiling, but command llvm-prof cannot read path profile info.

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

Problem solved. I was building llvm in a separate llvm-build directory. I built it within the llvm-src directory (which kept all the llvm .so and my pass' .so in the llvm-src/Release+Asserts/lib directory) to solve the problem. Can anyone tell me what's the difference between writing a pass as a "struct" (as in the tutorial) and as a "class" (as most developers do)?
