This retrieves CPU affinity via FreeBSD's cpuset(2) API, and makes LLVM respect affinity settings configured by the user via the cpuset(1) command. In particular, this allows to reduce the number of threads used on machines with high core counts, which can interact badly with parallelized build systems. This is particularly noticable with lld, which spawns lots of threads even for linking e.g. hello_world! This fix is related to PR48193, but does not adress the more fundamental problem, which is that LLVM by default grabs as many CPUs and/or threads as possible.

The LLVM Compiler Infrastructure ================================ This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments. LLVM is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt. Please see the documentation provided in docs/ for further assistance with LLVM, and in particular docs/GettingStarted.rst for getting started with LLVM and docs/README.txt for an overview of LLVM's documentation setup. If you are writing a package for LLVM, see docs/Packaging.rst for our suggestions.
