Work is progressing steadily on the clang/llvm integrated assembler, which removes the need for an external assembler such as gas, and which should also reduce compile times further. This is really in alpha state right now, but Roman Divacky (who is one of the active contributors) can probably tell more about its progress. Another important component is of course the linker, but I am not aware of a similar project to replace that; excepting gold, but that is a GPLv3 project too, unfortunately. There is also an LLDB Debugger project in the very early stages of development, see http://lldb.llvm.org/, but this works only on Mac OS X now. Volunteers are invited to port this to FreeBSD. :) Not binutils related, but still possibly interesting to FreeBSD, are also the libc++ and compiler-rt projects, a GNU libstdc++ replacement and a GNU libgcc replacement, respectively. See http://libcxx.llvm.org/ and http://compiler-rt.llvm.org/ for more information.
