Author: emaste Date: Wed May 30 18:04:25 2018 New Revision: 334391 URL: https://svnweb.freebsd.org/changeset/base/334391 Log: Enable lld as the system linker by default on amd64 The migration to LLVM's lld linker has been in progress for quite some time - about three years ago I opened an upstream LLVM meta-bug to track issues using lld as FreeBSD's linker, and about 1.5 years ago requested the first exp-run with lld as the system linker. As of r327783 we enabled LLD_BOOTSTRAP by default on amd64, using lld as the linker to link the kernel and world, but GNU ld was still installed as /usr/bin/ld. The vast majority of issues observed when building ports with lld as the system linker have now been solved, so set LLD_IS_LD by default on amd64 and install lld as /usr/bin/ld. A small number of port failures remain and these will be addressed in the near future. Thanks to antoine@ for handling the exp-runs, krion@ for investigating many port failures and adding LLD_UNSAFE or other fixes or workarounds, and everyone who helped investigate, fix or tag ports.
