I didn't know about --enable-symvers=gnu. The reason I put things into a v6 namespace is just to give us options for the future. If a v7 libstdc++ is different enough to need different printers, this approach would let us do that -- while also letting us have gdb sessions where different inferiors use different versions of libstdc++. The two sets of printers can still share code. For example, we could move most of the code to libstdcxx/printers.py and have the v6 and v7 variants import that. I am not sure what the best approach is for the current situation. What is the purpose of --enable-symvers=gnu? How different is the v7 library? Are there other possible configurations (configure- or user-compile-time) that affect printers that we haven't already accounted for?
