Go is an increasingly-popular systems programming language targeting, especially, concurrent and distributed systems. Go differentiates itself from other imperative languages by offering structural subtyping and lightweight concurrency through goroutines with message-passing communication. This combination of features poses interesting challenges for static verification, most prominently the combination of a mutable heap and advanced concurrency primitives. We present Gobra, a modular, deductive program verifier for Go that proves memory safety, crash safety, data-race freedom, and user-provided specifications. Gobra is based on separation logic and supports a large subset of Go. Its implementation translates an annotated Go program into the Viper intermediate verification language and uses an existing SMT-based verification backend to compute and discharge proof obligations.

Gobra：Go 程序的模块化规范和验证（扩展版）

Go 是一种越来越流行的系统编程语言，尤其是针对并发和分布式系统。Go 通过具有消息传递通信的 goroutines 提供结构化子类型和轻量级并发，从而将自己与其他命令式语言区分开来。这种特性组合对静态验证提出了有趣的挑战，最突出的是可变堆和高级并发原语的组合。我们展示了 Gobra，这是一个模块化的演绎程序验证器，用于证明内存安全、碰撞安全、数据竞争自由和用户提供的规范。Gobra 基于分离逻辑，支持 Go 的一大子集。
