<h1>Building and Installing Polly</h1>
|
|
You can build Polly with <a href="https://cmake.org/">cmake</a> and your preferred geneator (e.g. Ninja, make, Visual Studio, etc.).
|
|
|
|
<h3 id="source">Get the code</h3>
|
|
|
|
<pre>
|
|
git clone https://github.com/llvm/llvm-project.git
|
|
</pre>
|
|
|
|
You can also get a shallow clone by running:
|
|
|
|
<pre>
|
|
git clone --depth 1 https://github.com/llvm/llvm-project.git
|
|
</pre>
|
|
|
|
<h3 id="build">Build Polly</h3>
|
|
|
|
<pre>
|
|
mkdir build && cd build
|
|
cmake '-DLLVM_ENABLE_PROJECTS=clang;polly' ../llvm
|
|
cmake --build .
|
|
</pre>
|
|
|
|
You can also pass arguments to cmake to specify a particular generator (e.g. <code>-G Ninja</code>) or the build type (<code>-DCMAKE_BUILD_TYPE=Release</code>).
|
|
|
|
If you just want to play around with Polly, it is recommended to do a Release+Assert build by passing
|
|
<code>-DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=ON</code>.
|
|
|
|
<h3>Test Polly</h3>
|
|
|
|
To test Polly, you can run
|
|
|
|
<pre>cmake --build . --target check-polly</pre>
|
|
|
|
<h3>Using Polly</h3>
|
|
|
|
Suppose that you want to compile a program hello.c using Polly.
|
|
|
|
To compile it with Polly (in the build folder), you can run:
|
|
|
|
<pre>
|
|
bin/clang -O3 -mllvm -polly hello.c
|
|
</pre>
|
|
|
|
<h3> Troubleshooting</h3>
|
|
|
|
<p>
|
|
If you run out of memory when building with Ninja, try lowering the concurrency of Ninja (e.g. <code> ninja -j 2 </code>).
