I think the BSD folks may be interested. Which license covers SUN ld?

FreeBSD use GNU ld currently but don't like the GPLv3 license that binutils has switched to, so wew're at binutils v 2.15 (soon 2.17). gold has always been GPLv3. LLVM has llvm-ld, but there were problems with it last time I asked here (with native code generation, I think). There's a linker planned for the elftoolchain project, but it's still only a Trac ticket as far as I know.

I'd like to play with LTO for FreeBSD builds using Clang, but the options are limited as far as I can see.
