Since "amd64" and "arm64" look similar, let me clarify one point:
arm64 -- 64-bit ARM -- is built with, and has as /usr/bin/ld, LLD
4.0.0. This is true in HEAD and in stable/11 (and hence t

LLD 4.0.0 is in HEAD and stable/11, and WITH_LLD_IS_LD and
WITH_LLD_BOOTSTRAP are enabled by default for arm64 on both br

However some of the changes to FreeBSD haven't yet been merged to
stable/11, and it's probably not possible to build world + kernel with

Here's a fresh update on LLVM's LLD linker in the base system,
referencing the plan originally posted at the beginning of 2016. This
work is primarily taking place on amd64 right now, and unless
otherwise noted these results apply to amd64.
First, the completed items:

LLD developers have made much progress since my last update in August.
Two options used by the FreeBSD build, -dc and -r, are now
implemented. The issues with linker script expression support and
symbol version maps have been addressed. At this point an LLD built
from subversion can link a working

A quick update: most of the required changes have now made it into
LLD, and

For some reason Warner's email didn't make it to me, but I spotted it

Over the past year or so I have been investigating the state of LLVM's
lld linker for use in the FreeBSD base system, to see if it could be
used as FreeBSD's system linker.
Why do we need a new linker? Compared to the GNU ld 2.17.50 that we
have in the FreeBSD base system, lld will bring:
