LLD, which touts great performance improvements over GCC ld, will be included in LLVM 4 rc1 and enabled by default. Although the new linker is already able to build a running FreeBSD/amd64 base system, its inclusion in LLVM is still experimental and could be set back in rc2 if it causes problems.

MIT Extended LLVM IR to Enable Better Optimization of Parallel Programs

by Sergio De Simone on  Feb 06, 2017

Researchers at MIT have been working on a fork of LLVM to explore a new approach to optimizing parallel code by embedding fork-join parallelism directly into the compiler’s intermediate representation (IR). This, the researchers maintain, makes it possible to leverage most of the IR-level serial optimizations for parallel programs.
