Thanks for the reply. I thought the original comment in that BZ was talking about plans to remove the current forking of an "addr2line" process and communicating via pipe with some library implementation. Of course what that library would be if not BFD/LLVM was my question. Clearly this was a misread on my part. I'd seen the patches related to dlopen'ing llvm, backporting this is a possibility since we don't want a rpm requires. Cheers! Tony -- Tony Jones SUSE Kernel Performance Team
