[lldb-dev] Clang macro debug info

[Jim Ingham via lldb-dev]

You should ask on a clang list for a 100% correct answer, but I am pretty sure clang does not support macro information.  You can get somewhat the same result by building clang modules and importing them into lldb.  But you can't build modules for C++ yet, so you can only do this for C & ObjC programs.
