• LLVM Command Guide - A reference manual for the LLVM command line utilities ("man" pages for LLVM tools).
  Current tools: llvm-ar, llvm-as, llvm-dis, llvm-extract, llvm-ld, llvm-link, llvm-nm, llvm-prof, llvm-ranlib, opt, llc, lli, llvmc llvm-gcc, llvm-g++, bugpoint, llvm-bcanalyzer,
• LLVM's Analysis and Transform Passes - A list of optimizations and analyses implemented in LLVM.
• Frequently Asked Questions - A list of common questions and problems and their solutions.
• Release notes for the current release - This describes new features, known bugs, and other limitations.
• How to Submit A Bug Report - Instructions for properly submitting information about any bugs you run into in the LLVM system.
• LLVM Testing Infrastructure Guide - A reference manual for using the LLVM testing infrastructure.
• How to build the Ada/C/C++/Fortran front-ends - Instructions for building gcc front-ends from source.
• Packaging guide - Advice on packaging LLVM into a distribution.
• The LLVM Lexicon - Definition of acronyms, terms and concepts used in LLVM.
• You can probably find help on the unofficial LLVM IRC channel. We often are on irc.oftc.net in the #llvm channel. If you are using the mozilla browser, and have chatzilla installed, you can join #llvm on irc.oftc.net directly.

• LLVM Language Reference Manual - Defines the LLVM intermediate representation and the assembly form of the different nodes.
• The LLVM Programmers Manual - Introduction to the general layout of the LLVM sourcebase, important classes and APIs, and some tips & tricks.
• LLVM Project Guide - How-to guide and templates for new projects that use the LLVM infrastructure. The templates (directory organization, Makefiles, and test tree) allow the project code to be located outside (or inside) the llvm/ tree, while using LLVM header files and libraries.
• LLVM Makefile Guide - Describes how the LLVM makefiles work and how to use them.
• CommandLine library Reference Manual - Provides information on using the command line parsing library.
• LLVM Coding standards - Details the LLVM coding standards and provides useful information on writing efficient C++ code.
• Extending LLVM - Look here to see how to add instructions and intrinsics to LLVM.
• Using LLVM Libraries - Look here to understand how to use the libraries produced when LLVM is compiled.
• How To Release LLVM To The Public - This is a guide to preparing LLVM releases. Most developers can ignore it.
• Doxygen generated documentation (classes) (tarball)
• ViewVC Repository Browser

• Writing an LLVM Pass - Information on how to write LLVM transformations and analyses.
• Writing an LLVM Backend - Information on how to write LLVM backends for machine targets.
• The LLVM Target-Independent Code Generator - The design and implementation of the LLVM code generator. Useful if you are working on retargetting LLVM to a new architecture, designing a new codegen pass, or enhancing existing components.
• TableGen Fundamentals - Describes the TableGen tool, which is used heavily by the LLVM code generator.
• Alias Analysis in LLVM - Information on how to write a new alias analysis implementation or how to use existing analyses.
• Accurate Garbage Collection with LLVM - The interfaces source-language compilers should use for compiling GC'd programs.
• Source Level Debugging with LLVM - This document describes the design and philosophy behind the LLVM source-level debugger.
• Zero Cost Exception handling in LLVM - This document describes the design and implementation of exception handling in LLVM.
• Bugpoint - automatic bug finder and test-case reducer description and usage information.
• Compiler Driver (llvmc) Tutorial - This document is a tutorial introduction to the usage and configuration of the LLVM compiler driver tool, llvmc.
• Compiler Driver (llvmc) Reference - This document describes the design and configuration of llvmc in more detail.
• LLVM Bitcode File Format - This describes the file format and encoding used for LLVM "bc" files.
• System Library - This document describes the LLVM System Library (lib/System) and how to keep LLVM source code portable
• Link Time Optimization - This document describes the interface between LLVM intermodular optimizer and the linker and its design
• The LLVM gold plugin - How to build your programs with link-time optimization on Linux.
• The GDB JIT interface - How to debug JITed code with GDB.

• The LLVM Announcements List: This is a low volume list that provides important announcements regarding LLVM. It gets email about once a month.
• The Developer's List: This list is for people who want to be included in technical discussions of LLVM. People post to this list when they have questions about writing code for or using the LLVM tools. It is relatively low volume.
• The Bugs & Patches Archive: This list gets emailed every time a bug is opened and closed, and when people submit patches to be included in LLVM. It is higher volume than the LLVMdev list.
• The Commits Archive: This list contains all commit messages that are made when LLVM developers commit code changes to the repository. It is useful for those who want to stay on the bleeding edge of LLVM development. This list is very high volume.
• The Test Results Archive: A message is automatically sent to this list by every active nightly tester when it completes. As such, this list gets email several times each day, making it a high volume list.
