Building LLVM and Understanding the Directory Structure
The LLVM infrastructure provides a set of libraries that can be assembled to create different tools and compilers.
LLVM originally stood for Low-Level Virtual Machine. Nowadays, it is much more than that, as you will shortly learn, and people just use LLVM as a name.
Given the sheer volume of code that makes the LLVM repository, it can be daunting to even know where to start.
In this chapter, we will give you the keys to approach and use this code base confidently. Using this knowledge, you will be able to do the following:
- Understand the different components that make a compiler
- Build and test the LLVM project
- Navigate LLVM’s directory structure and locate the implementation of different components
- Contribute to the LLVM project
This chapter covers the basics needed to get started with LLVM. If you are already familiar with the LLVM infrastructure or followed the tutorial...
