[LLVMdev] Path profiling command
...ath 4. Run program to get profile info ./foo_path –llvmprof-out 5. Create path count map from raw data opt –path-profile-loader-file =llvmprof.out –path-profile-loader foo_path.bc –o path.out 6. Load Profile info: llvm-prof path.out The error message from llvm-prof is: llvm-prof: Unkknown packet #5 Could you explain me the error message? Are there errors in the command chain? What is the format of file llvmprof.out? Is it possible to read llvmprof.out from command llvm-prof by ignoring step 5? What is the purpose of command in step 5? Thanks so much Linh -------------- nex...

So I have to write my own pass to output the path profiling result,the following is my kernel codes: //////////////////////////////////////////////////////////////////////////////////// bool PathProfileOutput::runOnModule(Module &M) { PathProfileInfo& pathP...
