<p>The <b>Interactive Compilation Interface</b> (<b>ICI</b>) is a plugin system with a high-level compiler-independent and low-level compiler-dependent API to transform production compilers into interactive research toolsets. It was developed by <a href="Grigori_Fursin" title="Grigori Fursin">Grigori Fursin</a> during the <a href="MILEPOST_GCC" title="MILEPOST GCC">MILEPOST project</a>.<sup id="cite_ref-cti_2-0" class="reference"><a href="#cite_note-cti-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> The ICI framework acts as a "middleware" interface between the compiler and the user-definable plugins. It opens up and reuses the production-quality compiler infrastructure to enable program analysis and instrumentation, fine-grain program optimizations, simple prototyping of new development and research ideas while avoiding building new compilation tools from scratch. For example, it is used in <a href="MILEPOST_GCC" title="MILEPOST GCC">MILEPOST GCC</a> to automate compiler and architecture design and program optimizations based on statistical analysis and machine learning, and predict profitable optimization to improve program execution time, code size and compilation time.

<p>ICI is now available in mainline <a href="GNU_Compiler_Collection" title="GNU Compiler Collection">GCC</a> since version 4.5<sup id="cite_ref-gcc-plugins_1-1" class="reference"><a href="#cite_note-gcc-plugins-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>
</p><p>ICI was extended during the <a rel="nofollow" class="external text" href="https://web.archive.org/web/20110728122409/http://socghop.appspot.com/org/home/google/gsoc2009/gcc">Google Summer of Code'2009</a> to enable fine-grain program optimizations including polyhedral transformations, function level run-time adaptation and collective optimization.
