编译器和解释器的分界线在哪,字节码效率能否无限接近机器码?
栏目: 发布时间:

没有分界线,编译器和解释器被统一在了被称为 扶她映射(Futamura Projections)的大框架内。

Partial Evaluation而在讨论 Futamura Projection 之前,先要理解 偏计算(Partial Evaluation)技术。

偏计算是一种程序优化技术,其核心思想是: 如果一个程序 [公式] 的静态输入部分 [公式] 是已知的,而其余动态输入 [公式] 未知,那么我们可以通过一个称为“混合器”(mix)的特殊偏计算程序,将 [公式] 和已知的 [公式] 结合起来,生成一个新的、特化的程序 [公式]。
