在最高优化级别上，根据从正在执行的代码自动生成的动态分析数据执行重新编译。
At the highest optimization level, the recompilation is performed based on dynamic profiling data automatically generated from the executing code.
预先编译的代码有着静态的本质——与JIT编译器动态生成的代码不同，因而不可能在经过一段时间后，得益于常用方法的进一步优化。
Because of its static nature, precompiled code — unlike code generated dynamically by a JIT compiler — can't benefit from further optimisations of frequently used methods over time.
在传统编译器中，指令选择往往采用动态规划的方法，其目的是优化目标代码性能(减小程序运行时间)。
Instruction selection of traditional compilers often adopts the dynamic programming technology to optimize the object code performance (reducing code running time).
动态代码生成技术是一种在运行时刻生成可执行代码的技术，可以用来实现各种程序优化。
Dynamic code Generation is a kind of technology that generates executable code at runtime, which can be used to implement various program optimization.
