Overview
|
||
========
|
||
|
||
.. warning::
|
||
|
||
If you are using a released version of LLVM, see `the download page
|
||
<http://llvm.org/releases/>`_ 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:
|
||
|
||

User Guides
|

===========
|
||
|
||
For those new to the LLVM system.
|
||
|
||
NOTE: If you are a user who is only interested in using LLVM-based
|
||
compilers, you should look into `Clang <http://clang.llvm.org>`_ or
|
||
`DragonEgg <http://dragonegg.llvm.org>`_ instead. The documentation here is
|
||
intended for users who have a need to work with the intermediate LLVM
|
||
representation.

|
||
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.

Community
|
||
=========
|
||
|
||
LLVM has a thriving community of friendly and helpful developers.
|
||
The two primary communication mechanisms in the LLVM community are mailing
|
||
lists and IRC.
|
||
|
||
Mailing Lists
|
||
-------------
|
||
|
||
If you can't find what you need in these docs, try consulting the mailing
|
||
lists.
|
||
|
||
`Developer's List (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.
|
||
|
||
.. __: http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev
|
||
|
||
`Commits Archive (llvm-commits)`__
|
||
This list contains all commit messages that are made when LLVM developers
|
||
commit code changes to the repository. It also serves as a forum for
|
||
patch review (i.e. send patches here). It is useful for those who want to
|
||
stay on the bleeding edge of LLVM development. This list is very high
|
||
volume.
|
||
|
||
.. __: http://lists.cs.uiuc.edu/pipermail/llvm-commits/
|
||
|
||
`Bugs & Patches Archive (llvmbugs)`__
|
||
This list gets emailed every time a bug is opened and closed. It is
|
||
higher volume than the LLVMdev list.
|
||
|
||
.. __: http://lists.cs.uiuc.edu/pipermail/llvmbugs/
|
||
|
||
`Test Results Archive (llvm-testresults)`__
|
||
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.
|
||
|
||
.. __: http://lists.cs.uiuc.edu/pipermail/llvm-testresults/
|
||
|
||
`LLVM Announcements List (llvm-announce)`__
|
||
This is a low volume list that provides important announcements regarding
|
||
LLVM. It gets email about once a month.
|
||
|
||
.. __: http://lists.cs.uiuc.edu/mailman/listinfo/llvm-announce
|
||
|
||
IRC
|
||
---
|
||
|
||
Users and developers of the LLVM project (including subprojects such as Clang)
|
||
can be found in #llvm on `irc.oftc.net <irc://irc.oftc.net/llvm>`_.
|
||
|
||
This channel has several bots.
|
||
|
||
* Buildbot reporters
|
||
|
||
* llvmbb - Bot for the main LLVM buildbot master.
|
||
http://lab.llvm.org:8011/console
|
||
* bb-chapuni - An individually run buildbot master. http://bb.pgr.jp/console
|
||
* smooshlab - Apple's internal buildbot master.
|
||
|
||
* robot - Bugzilla linker. %bug <number>
|
||
|
||
* clang-bot - A `geordi <http://www.eelis.net/geordi/>`_ instance running
|
||
near-trunk clang instead of gcc.
