Summary

The LLVM umbrella is composed of several projects; some of them are not necessary for the main compiler driver to work but are useful tools and libraries. In this chapter, we showed how one can build and install such components. Further chapters will explore in detail some of those tools. We advise the reader to come back to this chapter again for build and install instructions.

In the next chapter, we will introduce you to the design of the LLVM core libraries and tools.
