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

LLVM (2.7 release version) provides 2 implementations for inlining function callsites: - InlineSimple.cpp (-inline): inline simple callsites according to its cost analysis - InlineAlways.cpp (-always-inline): inline all callsites that are marked with "always_inline" attribute. They are both subclasses of Inline.cpp that assumes the function's definition (body) is

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 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

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

I am using llvm for source-to-source inlining. So I did: % llvm-gcc file_a.c file_b.c ... file_n.c -o file % opt -inline -inline-threshold=1000 < file.bc | llc -march=c > outfile.c Can anyone tell me how llvm determines if a function should be inlined, and what roll does "inline-threshold" play ? (Does the example mean that if the function body has fewer than 1000 instructions,

I am investigating some inlining issue, so I did llvm-gcc aaa.c bbb.c ... nnn.c -o output opt -inline -inline-threshold=xxx < output.bc | llc -march=c > output_inline.c 1) I noticed that even if I set xxx to 0 or even a very small negative number, many functions are eliminated. I am wondering if these functions are inlined by the frontend, or identified as deadcode. For instance,

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

This didn't work as I tried with 197.parser. it works without "-Wl,-disable-opt" switch though.

However, I do know that your methods above run the LLVM inlining pass, albeit indirectly. If you use

Hello, I trying TSAN on Darwin on LLVM itself (sanitizing multi-threaded ThinLTO link). However I see two main issues on my debug build: 1) Statistics: the pre/post increment is not safe, it seems to be acknowledge in the code itself: // FIXME: This function and all those that follow carefully use an // atomic operation to update the value safely in the presence of // concurrent

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?
