Yes, LLDB can do this. When you are symbolicating, are you symbolicating using an address from a live process, or just using the virtual addresses in an object file itself?
If you are symbolicating using an address from the file, we already have a little C++ example for you: https://llvm.org/svn/llvm-project/lldb/trunk/examples/lookup/main.cpp If you want to load a bunch of files from a process at the addresses they were at when a backtrace or sample was taken, let me know. The example would change a little bit, but not too much.
