Hello, My name is Rantao Chen and i am a student at the University of Maryland. I am currently doing some research for a professor to do Basic Block profiling using LLVM. I have set up the environment correctly and built the profile_rt.so shared library, but i am having some problems using the LLVM profiling tools. I run "opt -insert-function-profiling -insert-block-profiling input.bc

Hi Rantao, perhaps you should use $llvmpath/utils/profile.pl for profiling? It works well. If you don't want to use it, there is at least some code in the script that should help you. BTW: I'm not sure if it is possible to instrument the bitcode with function and basic block code at the same time. But it should work sequential (data in llvmprof.out are accumulated after each run

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 Andreas, Thanks for breaking things up. I applied two pieces of this patch in separate no-functionality-change commits, here: http://llvm.org/viewvc/llvm-project?view=rev&revision=75623 and here: http://llvm.org/viewvc/llvm-project?view=rev&revision=75625 I merged in my changes to your patch, which results in the attached patch. There may be some missed merge errors. The main

How can I do function profiling and BB profiling with current llvm and llvm-gcc4? runtime/libprofile is disabled when using llvm-gcc4, but... is there any alternative to linking with libprofile_rt.so? How can I use llvm-prof? is utils/profile.pl obsolete? Thanks in advance, josem

The profiling support in LLVM hasn't been used for quite a

Hi, this is the first in a series of patches to cleanup and improve the LLVM Profiling Infrastructure. First and foremost this patch removes duplicate functionality from ProfileInfoLoader and ProfileInfo: The ProfileInfoLoader performed not only the loading of the profile information but also some synthesis of block and function execution counts from edge profiling information. Since the

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 all, I have already checked some related posted messages, such as: http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-January/012315.html and http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-February/012466.html After getting rid of some error messages, I was able to run the following commands: 1) opt -insert-path-profiling matmul.bc -o matmul.pp.bc 2) lli -load

I have not made a separate pass. I have done it in single pass ie added ProfileLoaderPass , got information in PI and now I am planning to perform the analysis here itself. I was trying to print information using ProfileInfoPrinter pass but was unable to do it. namespace { class MyAna : public ModulePass { ProfileInfo *PI; public: static char ID; // Class identification, replacement

Hi, I wanted to install llvm 1.8 and the frontend at my MacBook Pro but I think the gcc4 frontend doesn't work (gcc3 and llvm 1.8 works fine on my old ppc-based mac). There are no fixheaders-script and no include directories ... Are there working gcc 4 binaries? Did I miss some informations on the llvm-webpage? Or do I have to build my own gcc frontend? Thank you Nico

Hi, I am using Path Profiling to path profile a C code. I'm using this commands: $ llvm-gcc -c -emit-llvm file.c -o file.bc $ opt --insert-hotpath-profiling file.bc -o file.ins.bc $ llc -march=x86 file.ins.bc -o file.ins.s $ gcc -I llvm2.9/runtime/PathProfling.c -I llvm2.9/runtime/CommonProfiling.c $ ./a.out This will give me path profile of of program in 'llvmpro.out' to decode
