The bulk of libcxxrt is an older demangler (that doesn't support C++'0x) that I think they're planning to drop. The rest of the code is relatively minor stuff like implementation of std::bad_alloc and a few other glue things that should be straight-forward to implement in libc++abi. Since adding an external dependency complicates the licensing and distribution model, we're prefer to keep the LLVM libc++abi independent of libcxxrt.</div><div><br></div><div>-Chris </div><br></body></html>
