Summary
In this chapter, you learned how to set up your development environment and how to find the required version of the different tools to build the different versions of the LLVM infrastructure, including the open-source repository. This is a necessary step to be able to get started with building the LLVM infrastructure.
Next, you discovered the main components that make a compiler toolchain, namely the driver, frontend, backend, linker, and standard library, and which LLVM project they map to. This information will come in handy when you decide what you want to build out of the LLVM infrastructure.
After that, you dove into the build configurations of the core LLVM project and learned how to tweak the CMake variables to tailor the build to your needs while balancing the debuggability of the produced artifacts and the build time. You also learned how to use Ninja, the driver of the build system, efficiently to reduce the turnaround time between development, building,...
