+Software systems have been using “just-in-time” compilation (JIT) techniques since the
+1960s. Broadly, JIT compilation includes any translation performed dynamically, after a
+program has started execution. We examine the motivation behind JIT compilation and
+constraints imposed on JIT compilation systems, and present a classification scheme for
+such systems. This classification emerges as we survey forty years of JIT work, from
+1960–2000.

+
+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：
+- 介绍了JIT每一代出现的动机和约束条件
+- 介绍了对各种JIT技术的分类方式
+  > 1. Invocation
+  > 2. Executability
+  > 3. Concurrency
+- 介绍了各个时期JIT技术的实现方式和优缺点
+
+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
+- Binary code generation.
+- Cache coherence.
+- Execution.
+
+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。
