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.
|
|
</p>
|
|
|
|
<p>
|
|
There are three main tasks for building a release of 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>

Review the documentation and ensure that it is up to date. The Release Notes

must be updated to reflect bug fixes, new known issues, and changes in the

list of supported platforms. The Getting Started Guide should be updated to
|

reflect the new release version number tag avaiable from Subversion and

|
changes in basic system requirements.

|
|
You can, optionally, create source and binary RPM packages for LLVM. These may
|
|
make it easier to get LLVM into a distribution. This can be done with the
|
|
following commands:
|
|
</p>
|
|
|
|
<div class="doc_code">
|
|
<pre>
|

make dist # Build the distribution source tarball
|
|
make dist-check # Check that the source tarball can build itself.
|
|
cp llvm-M.m.tar.gz /usr/src/redhat/SOURCES # Required by rpmbuild
|
|
make srpm # for source rpm
|
|
make rpm # for binary rpm
|
|
</pre>
|
|
</div>
|
|
|
|
<p>
|
|
First, use <tt>make dist</tt> to simply build the distribution. Any failures
|
|
need to be corrected (on the branch). Once <tt>make dist</tt> can be
|
|
successful, do <tt>make dist-check</tt>. This target will do the same thing as
|
|
the 'dist' target but also test that distribution to make sure it can build
|
|
itself and runs <tt>make check</tt> as well. This ensures that needed files
|
|
are not missing and that the src tarball can be successfully unpacked, built,
|
|
installed, and cleaned. Once you have a reliable tarball, you need to copy it
|
|
to the <tt>/usr/src/redhat/SOURCES</tt> directory which is a requirement of
|
|
the rpmbuild tool. The last two <tt>make</tt> invocations just run rpmbuild to
|
|
build either a source (<tt>srpm</tt>) or binary (<tt>rpm</tt>) RPM package.

|
|
<div class="doc_text">
|
|
<p>
|
|
Creating the LLVM GCC binary distribution requires performing the following
|
|
steps for each supported platform:
|
|
</p>
|
|
|
|
<ol>
|
|
<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>
|
|
Build the libraries in <tt>llvm/runtime</tt> and install them into the
|
|
created LLVM GCC installation directory.
|
|
</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.
|
|
</li>
|
|
|
|
<li>
|
|
Add the copyright files and header file fix script.
|
|
</li>
|
|
|
|
<li>
|
|
Archive and compress the installation directory. These can be found in
|
|
previous releases of the LLVM-GCC front-end.

The first thing you need to understand is that there are multiple make targets
|
|
to support this feature. Here's an overview, we'll delve into the details
|
|
later.
|
|
</p>
|
|
|
|
<ul>
|
|
<li><b>distdir</b> - builds the distribution directory from which the
|
|
distribution will be packaged</li>
|
|
<li><b>dist</b> - builds each of the distribution tarballs (tar.gz,
|
|
tar.bzip2, .zip). These can be built individually as well, with separate
|
|
targets.</li>
|
|
<li><b>dist-check</b> - this is identical to <tt>dist</tt> but includes a
|
|
check on the distribution that ensures the tarball can: unpack
|
|
successfully, compile correctly, pass '<tt>make check</tt>', and pass
|
|
'<tt>make clean</tt>'.</li>
|
|
<li><b>dist-clean</b>- this just does a normal clean but also cleans up the
|
|
stuff generated by the other three <tt>dist</tt> targets (above).</li>
|
|
</ul>
|
|
|
|
<p>
|
|
Okay, that's the basic functionality. When making a release, we want to ensure
|
|
that the tree you build the distribution from passes
|
|
<tt>dist-check</tt>. Beyond fixing the usual bugs, there is generally one
|
|
impediment to making the release in this fashion: missing files. The
|
|
<tt>dist-check</tt> process guards against that possibility. It will either
|
|
fail and that failure will indicate what's missing, or it will succeed meaning
|
|
that it has proved that the tarballs can actually succeed in building LLVM
|
|
correctly and that it passes <tt>make check</tt>.
|
|
</p>
|
|
</div>

|
|
<div class="doc_subsection">distdir</div>
|
|
<div class="doc_text">
|
|
<p>
|
|
This target builds the distribution directory which is the directory from
|
|
which the tarballs are generated. The distribution directory has the same
|
|
name as the release, e.g. LLVM-1.7). This target goes through the following
|
|
process:
|
|
</p>
|
|
|
|
<ol>
|
|
<li>First, if there was an old distribution directory (for the current
|
|
release), it is removed in its entirety and you see <tt>Removing old
|
|
LLVM-1.7</tt></li>
|
|
<li>Second, it issues a <tt>make all ENABLE_OPTIMIZED=3D1</tt> to ensure
|
|
that the everything in your tree can be built in release mode. Often
|
|
times there are discrepancies in building between debug and release
|
|
modes so it enforces release mode first. If that fails, the
|
|
<tt>distdir</tt> target fails too. This is preceded by the message
|
|
<tt>Making 'all' to verify build</tt>.</li>
|
|
<li>Next, it traverses your source tree and copies it to a new directory
|
|
that has the name of the release (<tt>LLVM-M.m</tt> in our current
|
|
case). This is the directory that will get tar'd. It contains all the
|
|
software that needs to be in the distribution. During the copying
|
|
process, it omits generated files, SVN directories, and any other
|
|
"cruft" that's in your build tree. This is done to eliminate the
|
|
possibility of huge distribution tarballs that include useless or
|
|
irrelevant stuff in them. This is the trickiest part of making the
|
|
distribution. Done manually you will either include stuff that
|
|
shouldn't be in the distribution or exclude stuff that should. This
|
|
step is preceded by the message <tt>Building Distribution Directory
|
|
LLVM-1.7</tt></li>
|
|
<li>The distribution directory is then traversed and all <tt>CVS</tt> or
|
|
<tt>.svn</tt> directories are removed. You see: <tt>Eliminating CVS/.svn
|
|
directories from distribution</tt></li>
|
|
<li>The recursive <tt>dist-hook</tt> target is executed. This gives each
|
|
directory a chance to modify the distribution in some way (more on this
|
|
below).</li>
|
|
<li>The distribution directory is traversed and the correct file
|
|
permissions and modes are set based on the type of file.</li>
|
|
</ol>
|
|
|
|
<p>
|
|
To control the process of making the distribution directory correctly, each
|
|
Makefile can utilize two features:
|
|
</p>
|
|
|
|
<ol>
|
|
<li><b><tt>EXTRA_DIST</tt></B> - this make variable specifies which files
|
|
it should distribute. By default, all source files are automatically
|
|
included for distribution as well as certain <tt>well known</tt> files
|
|
(see DistAlways variable in Makefile.rules for details). Each Makefile
|
|
specifies, via the <tt>EXTRA_DIST</tt> variable, which additional files
|
|
need to be distributed. Only those files that are needed to build LLVM
|
|
should be added to <tt>EXTRA_DIST</tt>. <tt>EXTRA_DIST</tt> contains a
|
|
list of file or directory names that should be distributed. For example,
|
|
the top level Makefile contains <tt>EXTRA_DIST := test llvm.spec
|
|
include</tt>. This means that in addition to regular things that are
|
|
distributed at the top level (<tt>CREDITS.txt, LICENSE.txt</tt>, etc.)
|
|
the distribution should contain the entire <tt>test</tt> and
|
|
<tt>include</tt> directories as well as the <tt>llvm.spec</tt> file.</li>
|
|
<li><b><tt>dist-hook</tt></B> - this make target can be used to alter the
|
|
content of the distribution directory. For example, in the top level
|
|
Makefile there is some logic to eliminate files in the <tt>include</tt>
|
|
subtree that are generated by the configure script. These should not be
|
|
distributed. Similarly, any <tt>dist-hook</tt> target found in any
|
|
directory can add or remove or modify things just before it gets
|
|
packaged. Any transformation is permitted. Generally, not much is
|
|
needed.</li>
|
|
</ol>
|
|
|
|
<p>
|
|
You will see various messages if things go wrong:
|
|
</p>
|
|
|
|
<ol>
|
|
<li>During the copying process, any files that are missing will be flagged
|
|
with: <tt>===== WARNING: Distribution Source 'dir/file' Not Found!</tt>
|
|
These must be corrected by either adding the file or removing it from
|
|
<tt>EXTRA_DIST</tt>.</li>
|
|
<li>If you build the distribution with <tt>VERBOSE=1</tt>, then you might
|
|
also see: <tt>Skipping non-existent 'dir/file'</tt> in certain cases
|
|
where it's okay to skip the file.</li>
|
|
<li>The target can fail if any of the things it does fail. Error messages
|
|
should indicate what went wrong.</li>
|
|
</ol>

This target does exactly what <tt>distdir</tt> target does, but also includes
|
|
assembling the tarballs. There are actually four related targets here:
|
|
</p>
|
|
|
|
<ul>
|
|
<li><b><tt>dist-gzip</tt></b>: package the gzipped distribution tar
|
|
file. The distribution directory is packaged into a single file ending
|
|
in <tt>.tar.gz</tt> which is gzip compressed.</li>
|
|
<li><b><tt>dist-bzip2</tt></b>: package the bzip2 distribution tar file.
|
|
The distribution directory is packaged into a single file ending in
|
|
<tt>.tar.bzip2</tt> which is bzip2 compressed.</li>
|
|
<li><b><tt>dist-zip</tt></b>: package the zip distribution file. The
|
|
distribution directory is packaged into a single file ending in
|
|
<tt>.zip</tt> which is zip compressed.</li>
|
|
<li><b><tt>dist</tt></b>: does all three, dist-gzip, dist-bzip2,
|
|
dist-zip</li>
|
|
</ul>
|
|
</div>
|
|
|
|
<!-- ======================================================================= -->
|
|
<div class="doc_subsection">dist-check</div>
|
|
<div class="doc_text">

This target checks the distribution. The basic idea is that it unpacks the
|
|
distribution tarball and ensures that it can build. It takes the following
|
|
actions:
|
|
</p>
|
|
|
|
<ol>
|
|
<li>It depends on the <tt>dist-gzip</tt> target which, if it hasn't already
|
|
been built, builds the gzip tar bundle (see dist and distdir
|
|
above).</li>
|
|
<li>removes any pre-existing <tt>_distcheckdir</tt> at the top level.</li>
|
|
<li>creates a new <tt>_distcheckdir</tt> directory at the top level.</li>
|
|
<li>creates a <tt>build</tt> subdirectory and an <tt>install</tt>
|
|
subdirectory under <tt>_distcheckdir</tt>.</li>
|
|
<li>unzips and untars the release tarball into <tt>_distcheckdir</tt>,
|
|
creating <tt>LLVM-1.7</tt> directory (from the tarball).</li>
|
|
<li>in the build subdirectory, it configures with appropriate options to
|
|
build from the unpacked source tarball into the <tt>build</tt> directory
|
|
with installation in the <tt>install</tt> directory.</li>
|
|
<li>runs <tt>make all</tt></li>
|
|
<li>runs <tt>make </tt><tt>check</tt></li>
|
|
<li>runs <tt>make install</tt></li>
|
|
<li>runs <tt>make uninstall</tt></li>
|
|
<li>runs <tt>make dist</tt></li>
|
|
<li>runs <tt>make clean</tt></li>
|
|
<li>runs <tt>make dist-clean</tt></li>
|
|
</ol>
|
|
|
|
<p>
|
|
If it can pass all that, the distribution will be deemed distribution worth y
|
|
and you will see:
|
|
</p>
|
|
|
|
<pre>===== LLVM-1.7.tar.gz Ready For Distribution =====</pre>
|
|
|
|
<p>
|
|
This means the tarball should then be tested on other platforms and have the
|
|
nightly test run against it. If those all pass, THEN it is ready for
|
|
distribution.
|
|
</p>
|
|
|
|
<p>
|
|
A note about disk space: using <tt>dist-check</tt> will easily triple the
|
|
amount of disk space your build tree is using. You might want to check
|
|
available space before you begin.

<div class="doc_subsection">dist-clean</div>

<div class="doc_text">
|
|
<p>
|
|
In addition to doing a normal <tt>clean</tt>, this target will clean up the
|
|
files and directories created by the distribution targets. In particular the
|
|
distribution directory (<tt>LLVM-X.X</tt>), check directory
|
|
(<tt>_distcheckdir</tt>), and the various tarballs will be removed. You do
|
|
this after the release has shipped and you no longer need this stuff in your
|
|
build tree.
