<a id="what-is-svf" class="anchor" href="#what-is-svf" aria-hidden="true"><span class="octicon octicon-link"></span></a>What is SVF?</h2>
<p>SVF is a static tool that enables scalable and precise interprocedural dependence analysis for C programs. SVF allows value-flow construction and pointer analysis to be performed iteratively, thereby providing increasingly improved precision for both. </p>

<a id="what-kind-of-analyses-does-svf-provide" class="anchor" href="#what-kind-of-analyses-does-svf-provide" aria-hidden="true"><span class="octicon octicon-link"></span></a>What kind of analyses does SVF provide?</h2>
<ul>
<li>Field-sensitive Andersen's pointer analysis and call graph construction</li>
<li>Sparse flow-sensitive pointer analysis</li>
<li>Value-flow dependence analysis</li>
<li>Interprocedural memory SSA</li>
<li>Detecting source-sink related bugs, such as memory leaks and incorrect file-open close errors.</li>
</ul>

<a id="how-to-setup-svf" class="anchor" href="#how-to-setup-svf" aria-hidden="true"><span class="octicon octicon-link"></span></a>How to setup SVF?</h2>
<p>Please download the <a href="https://github.com/unsw-corg/SVF">source code</a> of SVF and refer to this <a href="https://github.com/unsw-corg/SVF/wiki/Setup-Guide#getting-started"> step-by-step guide</a> to setup SVF.</p>
<h2>
<a id="how-to-run-svf" class="anchor" href="#how-to-run-svf" aria-hidden="true"><span class="octicon octicon-link"></span></a>How to run SVF?</h2>
<p>SVF analyzes a program by taking the LLVM IR of the program as its input. Please refer to <a href="https://github.com/unsw-corg/SVF/wiki/User-Guide#quick-start">this user guide</a> to run SVF with <a href="https://github.com/unsw-corg/SVF/wiki/Analyze-a-Simple-C-Program#an-example">a simple example</a> and generate the <a href="https://github.com/unsw-corg/SVF/wiki/User-Guide#analysis-outputs">outputs</a> of each analysis pass in your local machine.</p>
<p>Alternatively, we have also prepared a <a href="http://www.cse.unsw.edu.au/%7Ecorg/svf/SVF.ova">virtual machine image</a> for you to run SVF on any machine with VirtualBox installed. Please refer to this <a href="https://github.com/unsw-corg/SVF/wiki/Try-SVF-in-VirtualBox"> step-by-step guide</a> to try SVF in a VM. </p>
