I am aware of both. compiler-rt can be used to replace most of libgcc,
it will need some testing. IIRC FreeBSD run into some issues on MIPS for

libcxx is currently not an option as replacement for libstdc++:
(1) It doesn't provide the equivalent of libsupc++. There is currently
no Open Source alternative.

(2) Last time I checked it depended heavily on POSIX 2008 locale
support, which we don't have. An alternative is stdcxx from ASF (under
Apache 2.0 license). I have that one working in a different tree.
