Hi, when I first imported the new C++ stack with libc++, libc++abi and libunwind I wanted to find out if we really needed libc++abi as a shared library or not. Thus so far only libc++ is a shared object, while libc++abi is only provided as .a. My reasoning was that the ABI should never change, while the standard C++ library, which sits on top of the ABI, can. It turns out that libc++ (well, who would have thought) depends on libc++abi bits that are not linked in when using LLD. That probably is because libc++ does not do DT_NEEDED on libc++abi. Considering that our clang is configured to always link with -lc++ and -lc++abi I thought this should just work, but LLD seems to be a bit stricter on the dependencies.
Now we could start to link libc++ to libc++abi, but I think we should simply provide libc++abi as shared object as well. Thoughts? ok?
