摘要

融合是一种程序优化技术,通常使用特殊用途的编译器支持来实现。在本文中,我们提出了一种替代方法,将基于折叠的融合作为独立库实现。我们使用staging在折叠上组合操作;这些操作被部分求值,生成的代码不会构造不必要的中间数据结构。该技术扩展到对集合进行分区和分组。

Fold-based fusion as a library: a generative programming pearl
Fusion is a program optimisation technique commonly implemented using special-purpose compiler support. In this paper, we present an alternative approach, implementing fold-based fusion as a standalone library. We use staging to compose operations on folds; the operations are partially evaluated away, yielding code that does not construct unnecessary intermediate data structures. The technique extends to partitioning and grouping of collections.
