f you're getting into compilers or exploring LLVM internals, one of the most powerful things you can learn is how to build your own LLVM Pass.
I’ve put together a hands-on guide that walks you through creating an LLVM pass as a plugin — something that’s actually used in real-world compiler workflows.
💡 What You’ll Learn
How LLVM passes work internally
How to create a custom pass from scratch
How to structure your plugin
How to build it using CMake
How to dynamically load and run it in LLVM
🔧 Why This Matters
Most developers use compilers as a black box. But if you're serious about:
Compiler development
Performance optimization
Static analysis
Systems programming
…then understanding LLVM passes is a game-changer.

🧠 Who Is This For?
Students learning compilers
Engineers exploring LLVM
Anyone building tooling around code analysis or optimisation
