… it. The pass has been added to the PassBuilder, in an arbitrary location. The pass has also been added to the PassRegistry, so it can be called stand-alone from opt. There are two test cases to demonstrate how loop passes traverse loop nests. There is also a demo.sh script, in the root LLVM directory, that can be used to configure and build LLVM for the tutorial. This script will evolve as the demo is developed.

This is the first part of the Loop Optimization tutorial. The tutorial is divided into 5 parts/steps.
In this first part we start by introducing the basic framework required by a loop transformation pass in LLVM. We use the new pass manager to write our transformation.
