This document collects information about successfully releasing LLVM to the
public. It is the release manager's guide to ensuring that a high quality
- build of LLVM is released. Mostly, it's just a bunch of reminders of things to
- do at release time so we don't inadvertently ship something that is utility
- deficient.
+ build of LLVM is released.
</p>
<p>
- There are three main tasks for building a release of LLVM:
+ The following is the basic criteria for releasing LLVM:
</p>
<ol>
- <li>Create the LLVM source distribution.</li>
- <li>Create the LLVM GCC source distribtuion.</li>
- <li>Create a set of LLVM GCC binary distribtuions for each supported
- platform. These binary distributions must include compiled versions
- of the libraries found in <tt>llvm/runtime</tt> from the LLVM
- source distribution created in Step 1.</li>
+ <li>Successful configure and build.</li>
+ <li>Clean 'make check'.</li>
+ <li>No regressions in the testsuite from the previous release. This may
+ include performance regressions for major benchmarks.</li>
</ol>
</div>
+<!-- *********************************************************************** -->
+<div class="doc_section"><a name="process">Release Timeline</a></div>
+<!-- *********************************************************************** -->
+<div class="doc_text">
+The release manager should attempt to have a release every 3-4 months because LLVM
+does time based releases (instead of feature based). The release schedule should
+be roughly as follows:
+<ol>
+<li>Set code freeze and branch creation date for 3 months after last release
+date. Announce release schedule to the LLVM community and update the website.</li>
+<li>Create release branch and begin release process. </li>
+<li>Send out pre-release for first round of testing. Testing will last 7-10 days.
+During the first round of testing, regressions should be found and fixed. Patches
+are merged from mainline to the release branch.</li>
+<li>Generate and send out second pre-release. Bugs found during this time will
+not be fixed unless absolutely critical. Bugs introduce by patches merged in
+will be fixed and if so, a 3rd round of testing is needed.</li>
+<li>The release notes should be updated during the first and second round of
+pre-release testing.</li>
+<li>Finally, release!</li>

- Build the LLVM GCC front-end. The LLVM GCC front-end must be installed in
- a directory named <tt>cfrontend/<platform>/llvm-gcc</tt>. For
- example, the Sparc/Solaris directory is named
- <tt>cfrontend/sparc/llvm-gcc</tt>.
- </li>
+ <li>Download llvm-X.X, llvm-test-X.X, and the appropriate llvm-gcc4 binary.

+ </ol>
+ <p>Ask LLVM developers to submit the report and make check results to the list.
+ Verify that there are no regressions from the previous release. For

+
+ <p>The first round of pre-release testing will be the longest. During this time,

+ steps 4-8).</p>
+
+ <p>If this is the second round of testing, this is only to ensure the bug fixes

- Build the libraries in <tt>llvm/runtime</tt> and install them into the

- </li>
- <li>
- For systems with non-distributable header files (e.g. Solaris), manually
- remove header files that the GCC build process has "fixed." This process
- is admittedly painful, but not as bad as it looks; these header files are
- almost always easily identifiable with simple grep expressions and are
- installed in only a few directories in the GCC installation directory.
