## What it is
A collection of self-contained, out-of-tree LLVM passes that serve as a tutorial for learning LLVM development. It builds against a binary LLVM installation and includes CMake scripts, LIT tests, CI setup, and documentation, updated with every LLVM release.

## Use cases
- learn how to write LLVM passes
- tutorial for llvm ir transformations
- example out-of-tree llvm pass with cmake
- get started with llvm plugin development
- reference examples for llvm optimization passes
- learn compiler internals with llvm

## When to choose
- you are a novice wanting to learn LLVM pass development step by step
- you want modern, up-to-date examples matching the latest LLVM release
- you need complete, testable reference passes with build scripts and CI

## When to avoid
- you need a production compiler framework rather than teaching examples
- you want Clang-level tooling rather than LLVM IR passes
- you need an older LLVM version that the tutorial no longer targets

## Facets
- artifact type: learning-resource
- maturity: active
- function: compiler, developer-tools, documentation, testing
- domain: compilers, tutorials, developer-tools, education
- platform: cpp, cross-platform, cli
- tags: llvm, llvm-passes, llvm-ir, compiler-plugins, out-of-tree-passes, tutorial, cmake, lit-tests, linux, macos
