摘要

我们为无类型λ演算定义了一个小步语义,它跟踪了在计算过程中发生的β-约简。通过对计算轨迹进行抽象,利用抽象解释对k-CFA进行重构,并对基于约束的k-CFA进行语义化论证。跟踪语义的抽象解释还为在CFA中引入扩展运算符铺平了道路,这些运算符超越了现有的分析,这些分析都基于对有限状态空间的探索。我们定义了∇CFA,这是一种基于扩展的分析,它限制了调用堆栈中的周期,并且可以在相似的成本下获得比k-CFA更好的精度。

Trace-based control-flow analysis
We define a small-step semantics for the untyped λ-calculus, that traces the β-reductions that occur during evaluation. By abstracting the computation traces, we reconstruct k-CFA using abstract interpretation, and justify constraint-based k-CFA in a semantic way. The abstract interpretation of the trace semantics also paves the way for introducing widening operators in CFA that go beyond existing analyses, that are all based on exploring a finite state space. We define ∇CFA, a widening-based analysis that limits the cycles in call stacks, and can achieve better precision than k-CFA at a similar cost.
