Abstract

We propose a technique for synthesizing bidirectional programs from the corresponding unidirectional code plus input/output examples. The core ideas are: (1) constructing a sketch using the given unidirectional program as a specification, and (2) filling the sketch in a modular fashion by exploiting the properties of bidirectional programs. These ideas are enabled by our choice of programming language, HOBiT, which is specifically designed to maintain the unidirectional program structure in bidirectional programming, and keep the parts that control bidirectional behavior modular. To evaluate our approach, we implemented it in a tool called Synbit and used it to generate bidirectional programs for intricate microbenchmarks, as well as for a few larger, more realistic problems. We also compared Synbit to a state-of-the-art unidirectional synthesis tool on the task of synthesizing backward computations. This is an extended version of the paper “Synbit: Synthesizing Bidirectional Programs using Unidirectional Sketches”, published at OOPSLA 2021. In addition to the OOPSLA’21 paper, this journal will contain additional formalization and detailed examples.

Synbit：使用单向草图合成双向程序

我们提出了一种从相应的单向代码加上输入/输出示例合成双向程序的技术。其核心思想是(1) 使用给定的单向程序作为规范构建草图，(2) 利用双向程序的特性以模块化方式填充草图。我们选择的编程语言 HOBiT 使这些想法得以实现，该语言专门设计用于在双向编程中保持单向程序结构，并将控制双向行为的部分模块化。为了评估我们的方法，我们在一个名为 Synbit 的工具中实施了这种方法，并用它为复杂的微基准测试以及一些更大、更现实的问题生成了双向程序。我们还将 Synbit 与最先进的单向合成工具在反向计算合成任务上进行了比较。本文是论文 "Synbit：Synthesizing Bidirectional Programs using Unidirectional Sketches"（使用单向草图合成双向程序）一文的扩展版，已在 2021 年 OOPSLA 上发表。除 OOPSLA'21 论文外，本期刊还将包含更多形式化内容和详细示例。

期刊介绍： The focus of this journal is on formal methods for designing, implementing, and validating the correctness of hardware (VLSI) and software systems. The stimulus for starting a journal with this goal came from both academia and industry. In both areas, interest in the use of formal methods has increased rapidly during the past few years. The enormous cost and time required to validate new designs has led to the realization that more powerful techniques must be developed. A number of techniques and tools are currently being devised for improving the reliability, and robustness of complex hardware and software systems. While the boundary between the (sub)components of a system that are cast in hardware, firmware, or software continues to blur, the relevant design disciplines and formal methods are maturing rapidly. Consequently, an important (and useful) collection of commonly applicable formal methods are expected to emerge that will strongly influence future design environments and design methods.
