1 That seems a lot like what we've already done. I guess a GSOC student is working on the libcxxabi piece. The only advantage to using our runtime, libcxxrt, is performance and code size.‎

24 Currently the ebuilds for libunwind, libc++abi and libc++ all involve
25 some hackery to support standalone build. And the package clang is
26 just a placeholder, while it's actually built in llvm.
28 Maybe we can put them all into the llvm package, and control what
29 components to build via USE flags.
