Really? What happens if you link against libraries not built with C++11? Do you get undefined behaviour? We've been building and running our tools in clang/tools/extra with C++11 turned on and have had no trouble linking with clang libraries so far.

I can understand the reason for this in the LLVM and clang codebases as they're both widely used. However, would it be a problem to use C++11 officially in clang/tools/extra? It's not nearly as widely used and has less of a chance of impacting critical work in the community. Are there other problems I'm missing? If not, could the use of C++11 in clang/tools/extra be officially blessed?
One of the problems with doing this (as we've found with lld), is that you need to link it against a set of clang libraries that are also built with C++11.
