Rust is a new systems programming language that promises to overcome the seemingly
fundamental tradeoff between high-level safety guarantees and low-level control over …

The C and C++ programming languages are notoriously insecure yet remain indispensable.
Developers therefore resort to a multi-pronged approach to find security issues before …

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 …

Given the central role that C continues to play in systems software, and the difficulty of
writing safe and correct C code, it remains a grand challenge to develop effective formal …

This paper describes an approach to designing, implementing, and formally verifying the
functional correctness of an OS kernel, named Hyperkernel, with a high degree of proof …

Compilers assure that any produced optimized code is semantically equivalent to the
original code. However, even" correct" compilers may introduce security bugs as security …

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 …

The semantics of pointers and memory objects in C has been a vexed question for many
years. C values cannot be treated as either purely abstract or purely concrete entities: the …

Today's compilers employ a variety of non-trivial optimizations to achieve good performance.
One key trick compilers use to justify transformations of concurrent programs is to assume …
