4 LLVM welcomes contributions of all kinds. To get started, please review the following topics:
\r
16 SphinxQuickstartTemplate
\r
25 An overview on how to contribute to LLVM.
\r
27 :doc:`DeveloperPolicy`
\r
28 The LLVM project's policy towards developers and their contributions.
\r
31 The LLVM project's code-review process.
\r
33 :doc:`SupportPolicy`
\r
34 The LLVM support policy for core and non-core components.
\r
36 :doc:`SphinxQuickstartTemplate`
\r
37 A template + tutorial for writing new Sphinx documentation. It is meant
\r
38 to be read in source form.
\r
41 Describes how to use the Phabricator code review tool hosted on
\r
42 http://reviews.llvm.org/ and its command line interface, Arcanist.
\r
44 :doc:`HowToSubmitABug`
\r
45 Instructions for properly submitting information about any bugs you run into
\r
49 Describes how bugs are reported, triaged and closed.
\r
51 :doc:`CodingStandards`
\r
52 Details the LLVM coding standards and provides useful information on writing
\r
56 Describes how to use ``git bisect`` on LLVM's repository.
\r
58 :doc:`GitRepositoryPolicy`
\r
59 Collection of policies around the git repositories.
\r
61 .. _development-process:
\r
66 Information about LLVM's development process.
\r
79 How-to guide and templates for new projects that *use* the LLVM
\r
80 infrastructure. The templates (directory organization, Makefiles, and test
\r
81 tree) allow the project code to be located outside (or inside) the ``llvm/``
\r
82 tree, while using LLVM header files and libraries.
\r
84 :doc:`HowToReleaseLLVM`
\r
85 This is a guide to preparing LLVM releases. Most developers can ignore it.
\r
87 :doc:`ReleaseProcess`
\r
88 This is a guide to validate a new release, during the release process. Most developers can ignore it.
\r
90 :doc:`HowToAddABuilder`
\r
91 Instructions for adding new builder to LLVM buildbot master.
\r
94 Advice on packaging LLVM into a distribution.
\r
96 :doc:`Release notes for the current release <ReleaseNotes>`
\r
97 This describes new features, known bugs, and other limitations.
\r
104 If you can't find what you need in these docs, try consulting the mailing
\r
105 lists. In addition to the traditional mailing lists there is also a
\r
106 `Discourse server <https://llvm.discourse.group>`_ available.
\r
108 `Developer's List (llvm-dev)`__
\r
109 This list is for people who want to be included in technical discussions of
\r
110 LLVM. People post to this list when they have questions about writing code
\r
111 for or using the LLVM tools. It is relatively low volume.
\r
113 .. __: http://lists.llvm.org/mailman/listinfo/llvm-dev
\r
115 `Commits Archive (llvm-commits)`__
\r
116 This list contains all commit messages that are made when LLVM developers
\r
117 commit code changes to the repository. It also serves as a forum for
\r
118 patch review (i.e. send patches here). It is useful for those who want to
\r
119 stay on the bleeding edge of LLVM development. This list is very high
\r
122 .. __: http://lists.llvm.org/pipermail/llvm-commits/
\r
124 `Bugs & Patches Archive (llvm-bugs)`__
\r
125 This list gets emailed every time a bug is opened and closed. It is
\r
126 higher volume than the LLVM-dev list.
\r
128 .. __: http://lists.llvm.org/pipermail/llvm-bugs/
\r
130 `Test Results Archive (llvm-testresults)`__
\r
131 A message is automatically sent to this list by every active nightly tester
\r
132 when it completes. As such, this list gets email several times each day,
\r
133 making it a high volume list.
\r
135 .. __: http://lists.llvm.org/pipermail/llvm-testresults/
\r
137 `LLVM Announcements List (llvm-announce)`__
\r
138 This is a low volume list that provides important announcements regarding
\r
139 LLVM. It gets email about once a month.
\r
141 .. __: http://lists.llvm.org/mailman/listinfo/llvm-announce
\r
143 .. _online-sync-ups:
\r
148 A number of regular calls are organized on specific topics. It should be
\r
149 expected that the range of topics will change over time. At the time of
\r
150 writing, the following sync-ups are organized:
