    <p>Software systems have been using “just-in-time” compilation (JIT) techniques since the<br>1960s. Broadly, JIT compilation includes any translation performed dynamically, after a<br>program has started execution. We examine the motivation behind JIT compilation and<br>constraints imposed on JIT compilation systems, and present a classification scheme for<br>such systems. This classification emerges as we survey forty years of JIT work, from<br>1960–2000.</p>
<ul>
<li><a href="/papers/A%20Brief%20History%20of%20Just-In-Time.pdf">论文链接</a></li>
</ul>
<p>主要介绍了JIT的历史和发展过程， 从上世纪六十年代开始， 一直到现在的第四代JIT系统， 大概有三点：</p>
<ul>
<li>介绍了JIT每一代出现的动机和约束条件</li>
<li>介绍了对各种JIT技术的分类方式<blockquote>
<ol>
<li>Invocation</li>
<li>Executability</li>
<li>Concurrency</li>
</ol>
</blockquote>
</li>
<li>介绍了各个时期JIT技术的实现方式和优缺点</li>
</ul>
<p>除此之外还介绍了JIT的工具包以及它们在三个不同的方面的支持程度, 分别是</p>
<ul>
<li>Binary code generation.</li>
<li>Cache coherence.</li>
<li>Execution.</li>
</ul>
<p>总体来说，这篇论文算是一个概览，可以当成一个JIT相关论文的查询目录了，它把这过程中的所有研究全部以时间线的方式梳理起来，最后总结分类。</p>
