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

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?

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

Duncan: I am only superficially familiar with LLVM structure. What I am trying to find out is if functions that have a single invocation are still found in the code during the compilation. In Open64 and other compilers, there is an early inlining pass that inlines all procedures that have a single invocation site. The reasoning is that if there is a single call to a procedure, then there is not

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

This question is related with an evaluation of a research work that uses LLVM as a platform. Does LLVM implement an early inlining strategy? Does this early inlining strategy inlines all functions that are called only once in the program? Thanks, -- Cheers, Nelson / \ / / Jose Nelson Amaral - amaral at cs.ualberta.ca ) / ( Professor

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

Dear LLVM developers: I am a summer research student at the University of Alberta and I am working on implementing path profiling into LLVM. My work is almost complete; I am currently conducting tests to ensure that the path profiler functions correctly. To provide evidence that the profiler produces accurate results, I have developed a verifier which derives edge profile files (identical to

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

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

Hello I am trying to install R 2.6.0 on a SGI Origin 350 running IRIX 6.5 6.5.28f R was configured with the following options: > --x-includes=/usr/include/X11 > --x-libraries=/usr/lib/X11 > --includedir=/usr/freeware/include > --includedir=/usr/freeware/lib32 > --includedir=/usr/freeware/lib64 > --with-readline=no > --with-iconv=no > CC=cc gmake complied

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)?

Hey, folk. I am trying to get many figures by using the function "xyplot" in the library "lattice". I tried to using the loop to finish it quickly. But I cannot open the saved file after I run the program. But if I use the function "plot" to get other simply figures, it can work. So I want to ask how I can get the saved figures by using "xyplot". The
