# The LLVM Compiler Infrastructure
http://llvm.cs.uiuc.edu

## Welcome to LLVM!

This file is intended to do four things:

1. help you get started using LLVM;
2. tell you how to get questions about LLVM answered;
3. tell you where to find documentation for different kinds of questions; and
4. tell you about three LLVM-related mailing lists.

## Getting Started with LLVM

For license information:
  llvm/LICENSE.TXT

Installing and compiling LLVM:
  llvm/docs/GettingStarted.html

Learn about features and limitations of this release:
  llvm/docs/ReleaseNotes.html

Learn how to write a pass within the LLVM system:
  llvm/docs/WritingAnLLVMPass.html

Learn how to start a new development project using LLVM, where your new source code can live anywhere (outside or inside the LLVM tree), while using LLVM header files and libraries:
  llvm/docs/Projects.html

## Getting Help with LLVM

1. If you have questions or development problems not answered in the documentation, send e-mail to llvmdev@cs.uiuc.edu. This mailing list is monitored by all the people in the LLVM group at Illinois, and you should expect prompt first responses.
2. To report a bug, submit a bug report as described in the document: http://llvm.cs.uiuc.edu/docs/HowToSubmitABug.html
3. We now use Bugzilla to track bugs, so you can check the status of previous bugs at: http://llvm.cs.uiuc.edu/bugs/query.cgi

## LLVM Documentation

All the documents mentioned below except the design overview tech report are included as part of the LLVM release (in llvm/docs/*):

### LLVM Design Overview:

## Mailing Lists

There are three mailing lists for providing LLVM users with information:

1. LLVM Announcements List:
   http://mail.cs.uiuc.edu/mailman/listinfo/llvm-announce

   This is a low volume list that provides important announcements regarding LLVM. It is primarily intended to announce new releases, major updates to the software, etc. This list is highly recommended for anyone that uses LLVM.

2. LLVM Developers List:
   http://mail.cs.uiuc.edu/mailman/listinfo/llvmdev

   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.

3. LLVM Commits List
   http://mail.cs.uiuc.edu/mailman/listinfo/llvm-commits

   This list contains all commit messages that are made when LLVM developers commit code changes to the CVS archive. It is useful for those who want to stay on the bleeding edge of LLVM development. This list is very high volume.
