What is llvm-tutor?

The README for this project doesn't go into detail, as it contains no written description. However, based on the repository's title and the code it contains, it serves as a collection of example plugins for a programming tool infrastructure called LLVM. LLVM is a widely used toolkit that helps build compilers, the programs that translate code written by humans into instructions a computer can actually run. "Passes" are individual steps or modules within this system that examine and modify code as it goes through that translation process. This project provides pre-built examples of these steps, along with tests to verify they work correctly and build scripts to help compile them. People who would use this are typically developers learning how to build their own compiler tools or programming language features. For example, if a developer wanted to create a tool that automatically checks code for certain bugs during compilation, or one that optimizes code to make programs run faster, they would need to write LLVM passes. Having a set of working examples makes it much easier to understand the structure and syntax required to build these modules from scratch. The project appears to be an educational resource rather than something an end user would interact with directly. It's the kind of repository someone might clone to study, modify, and experiment with while learning the internals of how modern compilers work. Without further documentation, the code itself is the primary source of information for anyone looking to understand how the examples are structured.
