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

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 implementation strategies that won't benefit from this code being her...

Hello, I modified the PathProfiling.cpp and run opt -inesrt-path-profiling. it works correctly ,but after path-profile is complete in Verifier::visitTerminatorInst it prints "Terminator found in the middle of a basic block!" . error is I added two basic blocks after return basic block and return has br label %newprint w...

Hi, I am a student at IIT Kanpur. I am working on Path Profiling, i just came with a need to know about the number of static paths in a program(actually in a function) before it's actually get run. As i saw in PathProfiling.c file in llvm\runtime\libprofile they are just storing the path information at run time and dynamically adding entries for the new path. But i need to know the number of static paths (total paths in a function ) whether they are executed or not. Please help me know that, can LLVM provide me wit...

...ing 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 Thanks Naveed Ul Mustafa

We've been actively using it since at least 2.8. True, we haven't been vocal about it. While I can see perhaps getting rid of some of the older ProfileInfoT related stuff, certainly the instrumentation portion and the...

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

Is there anything about your proposed profiling method that requires the use of lli or llvm-ld? I'm assuming the instrumentor itself will simply be a Pass. Will this work in setups that use the machine's native linker...

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

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?

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
