Hi Krzysztof,
Please make sure you don't specify the triple if you don't need one, or
restrict the target if it's specific.
http://lab.llvm.org:8011/builders/clang-native-arm-cortex-a9/builds/5003/steps/check-all/logs/LLVM%20%3A%3A%20DebugInfo__dwarf-public-names.ll
Follow other examples on DebugInfo dir.
cheers,
