lld currently lacks comprehensive linker script expression evaluation support, and therefore cannot yet be used to link the FreeBSD kernel. It also lacks versioned symbol support, and does not implement some options used in the FreeBSD boot loader components.

Ed has been running experimental world builds of FreeBSD/amd64 with lld installed in place of ld.bfd as the linker. With workarounds for the current gaps in functionality (using the WITHOUT_SYMVER option to disable symbol versioning use, and linking the loader components with GNU ld), lld is now able to - link a working FreeBSD system.
