# BOLT is not respecting the component split of LLVM and requires some private
# headers in order to compile itself. Try to disable as much libraries as
# possible in order to reduce build time.

BOLT is a post-link optimizer developed to speed up large applications.
It achieves the improvements by optimizing application's code layout based
on execution profile gathered by sampling profiler, such as Linux perf tool.
