After more than twenty-five years of research, memory safety violations remain one of the
major causes of security vulnerabilities in real-world software. Memory-safe languages, like …

We designed, implemented, and deployed Alive2: a bounded translation validation tool for
the LLVM compiler's intermediate representation (IR). It limits resource consumption by, for …

Type systems are useful not just for the safety guarantees they provide, but also for helping
compilers generate more efficient code by simplifying important program analyses. In Rust …

We propose a testing framework for validating static typing procedures in compilers. Our
core component is a program generator suitably crafted for producing programs that are …

This paper presents a novel formal semantics, mechanized in Coq, for a large, sequential
subset of the LLVM IR. In contrast to previous approaches, which use relationally-specified …

Rust is a young systems programming language that aims to fill the gap between high-level
languages—which provide strong static guarantees like memory and thread safety—and low …

Program logics and semantics tell a pleasant story about sequential composition: when
executing (S1; S2), we first execute S1 then S2. To improve performance, however …

In process mining, procedural process models can be difficult to manage when the process
is unpredictable and characterized by many possible exceptions since they can easily …

Abstract LLVM [Lattner and Adve, 2004] is designed for the compile-time, link-time and run-
time optimization of programs written in various programming languages. The language …

Systems code often requires fine-grained control over memory layout and pointers,
expressed using low-level (eg, bitwise) operations on pointer values. Since these operations …
