This fixes most references to the paths: llvm.org/svn/ llvm.org/git/ llvm.org/viewvc/ github.com/llvm-mirror/ github.com/llvm-project/ reviews.llvm.org/diffusion/ to instead point to https://github.com/llvm/llvm-project. This is *not* a trivial substitution, because additionally, all the checkout instructions had to be migrated to instruct users on how to use the monorepo layout, setting LLVM_ENABLE_PROJECTS instead of checking out various projects into various subdirectories. I've attempted to not change any scripts here, only documentation. The scripts will have to be addressed separately. Additionally, I've deleted one document which appeared to be outdated and unneeded: lldb/docs/building-with-debug-llvm.txt Differential Revision: https://reviews.llvm.org/D57330 llvm-svn: 352514

<h1>Building and Installing Polly</h1>
|
|
|
|
<h2> Automatic </h2>
|
|
|
|
There is a <a href="polly.sh">script</a> available to automatically checkout,
|
|
update, build, and test Polly. This script contains all the commands that are
|
|
subsequently described on this webpage. The automatic installation consists
|
|
of four simple steps:
|
|
|
|
<pre>
|
|
mkdir polly && cd polly
|
|
wget http://polly.llvm.org/polly.sh
|
|
chmod +x polly.sh
|
|
./polly.sh
|
|
</pre>
|
|
|
|
<h2> Manual </h2>
|
|
<h3 id="source"> Get the code </h3>
|
|
|
|
<pre>
|
|
git clone http://github.com/llvm/llvm-project.git llvm_git
|
|
</pre>
|
|
<h3 id="build">Build Polly</h3>
|
|
|
|
<pre>
|
|
mkdir llvm_build && cd llvm_build
|
|
cmake -DLLVM_ENABLE_PROJECTS='polly;clang' ../llvm_git/llvm && make
|
|
</pre>
|
|
|
|
<h3> Test Polly</h3>
|
|
|
|
<pre>make check-polly</pre>
|
|
|
|
<h3>Building Polly Without LLVM</h3>
|
|
It is also possible to build Polly without
|
|
also building LLVM. All you need is an installed version of LLVM or a previous
|
|
build. To configure Polly to use a pre-built LLVM, set the
|
|
<code>-DCMAKE_PREFIX_PATH</code> option:
|
|
|
|
<pre>cmake -DCMAKE_PREFIX_PATH=${LLVM_PREFIX}/lib/cmake/llvm ../llvm_git/polly</pre>
|
|
|
|
To run unittests, however, you need to have the LLVM source directory around.
|
|
Polly will use the <code>llvm-config</code> of the LLVM you're building against
|
|
to guess the location of the source directory. You may override autodetected
|
|
location by setting the <code>-DLLVM_SOURCE_ROOT</code> option.
|
|
|
|
<h3> Troubleshooting</h3>
|
|
|
|
<p>If you get an error in one of the python files, your system probably uses python3
|
|
as default python interpreter. This is the case, for instance, under Arch Linux.
|
|
To solve this issue, run <code>cmake</code> again, but with the added argument:
|
|
<code>-DPYTHON_EXECUTABLE=/usr/bin/python2</code> (replace <code>/usr/bin/python2</code>
|
|
with the location of the python2 interpreter under your system).
|
|
|
|
<pre>cmake -DCMAKE_PREFIX_PATH=${ISL_INSTALL} -DPYTHON_EXECUTABLE=/usr/bin/python2 ${LLVM_SRC}</pre>
