Dear Neda, Please explain in more detail what you are trying to do and what is not working. I do not understand what llvm-prof does that you don't like or what you want llvm-prof to do. -- John T.

Thank you for your reply Yes, I change them, so what should I do for another loops?

hi all, I want access to all basic blocks of function in a loop, so I used the following code: *bool parallel::runOnLoop(Loop *L, LPPassManager &LPM) { for (Function::iterator bi= func->begin(); bi != func->end(); bi++){ // } }* First loop run without problem, but for second loop I get the following error: *0 libLLVM-2.9.so 0x0137d530 1 libLLVM-2.9.so 0x0137fa6c 2

I don't really know what you should do since I don't know what your code does. All I know is that it's changing the function's control-flow graph. If you're not modifying the structure of the loops in the function, then you can

i could not use profile.pl, however i did reinstall the llvm but didn't solve my problem. is there is another way to extract profilling information in llvm? i have another question, i want know how can estimate execution time for each operand such as mul ,add, ... ? -------------- next part -------------- An HTML attachment was scrubbed...

Hi, All I want to implement DSWP Which is used for parallelization of loops. For this purpose, the loop was replaced with a new basic block in main function. And new functions were created and basic blocks of Loop assigned to them.I have checked blocks and branches for Succ and Pred relation and I have not found any problems. However I get the following error: * **opt:

Hi all I want to use "'/home/llvm/src/utils/profile.pl' -edge sort.bc" command, but i face this error: Error opening '/usr/local/lib/profile_rt.so': /usr/local/lib/profile_rt.so: cannot open shared object file: No such file or directory -load request ignored. LLVM ERROR: Program used external function 'llvm_start_edge_profiling' which could not be resolved!

Hi all, I am looking appropriate Benchmarking for the assessment of automatic parallelization project. What Benchmarking do you suggest me? regards neda -------------- next part -------------- An HTML attachment was scrubbed...

I am changing structure of loops, I used std::vector<> but i get same error, I can’t use FunctionPass :( On Mon, Dec 12, 2011 at 8:03 PM, John Criswell <criswell at illinois.edu>wrote: > On 12/12/11 10:25 AM, neda 8664 wrote: > > Thank you for your reply > Yes, I change them, so what should I do for another loops? > > > I don't really know what you should

hi i have another question, how can change the display of result on screen?For this purpose, i have modified the llvm-prof file and make it again. But received no results

I want automatically parallelize sequential program in thread level to run on multi-core processors with software pipelining and use llvm. is it a suitable tools in this project ? can you help me in this topic? -------------- next part -------------- An HTML attachment was scrubbed...

I've study their work carefully. My problem is the implementation of threads in llvm after partitionning. I want to have information about how to implement producer/consumer thread in llvm. I do not know where I should start in llvm for code generation and create thread and insert produce and consume statement . -------------- next part -------------- An HTML attachment was scrubbed...

Hi, all I'm using profiling mechanism provided by LLVM. What I did is, $ ./${LLVM_SRC}/utils/profile.pl hello.bc But it turned out that llvm-prof failed to interpret the profile dump, llvm-prof gave me the error message below. llvm-prof: Unknown packet type #5! Any idea? Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica,

I can only guess llvm-prof does not recognize the profiling data. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia

Turns out I was using `opt -profile-loader` instead of `opt -path-profile-loader`. Switching to the path profile loader fixed the problem.

Yes, the latest version can be downloaded from here https://github.com/liuml07/giri . The LLVM instrumentation code is in TracingNoGiri.cpp<https://github.com/liuml07/giri/blob/master/lib/Giri/TracingNoGiri.cpp> file and runtime code in Tracing.cpp. You may need to delete other unnecessary instrumentation code which you don't need. Thanks, Swarup. ________________________________
