If you are using a released version of LLVM, see the download page to find your documentation.
The LLVM compiler infrastructure supports a wide range of projects, from industrial strength compilers to specialized JIT applications to small research projects.
Similarly, documentation is broken down into several high-level groupings targeted at different audiences:
LLVM Design & Overview¶
Several introductory papers and presentations.
- Introduction to the LLVM Compiler
Presentation providing a users introduction to LLVM.
- Intro to LLVM
A chapter from the book “The Architecture of Open Source Applications” that describes high-level design decisions that shaped LLVM.
- LLVM: A Compilation Framework for Lifelong Program Analysis & Transformation
- LLVM: An Infrastructure for Multi-Stage Optimization
More details (quite old now).
Getting Started, How-tos, Developer Guides, and Tutorials.
