Hi all: I am using llvm 3.3, which was compiled using the following configure options: ../llvm-3.3.src/configure --with-gcc-toolchain =/home/admin/jianzhang.zj/gcc-4.8.2-install --prefix =/home/admin/jianzhang.zj/llvm/llvm-install-3 --enable-optimized --enable -debug-runtime --enable-debug-symbols --disable-assertions --with-oprofile=/usr/local/ --enable-profiling then I compiled the Fibonacci example in the llvm source code, and I run the profiling using the command below: $ operf ./fibonacci 40 and then opreport: $ opreport -l samples % image name symbol name 147735 98.5360 anon (tgid:46343 range:0x7f9cdd4de000-0x7f9cdd55dfff) anon (tgid:46343 range:0x7f9cdd4de000-0x7f9cdd55dfff) as we see, there is a 'anon' in the result, the profiling result is not as I expected. Can anyone tell me how to profiling llvm JITed code? I hope hearing from you soon, thanks -------------- next part -------------- An HTML attachment was scrubbed...
