Alive2

A translation validation tool for LLVM, used to verify the correctness of compiler optimizations.

Product Information

Description
Alive2 is a translation validation tool designed to verify the correctness of compiler optimizations within the LLVM framework. It operates by comparing the behavior of original LLVM intermediate representation (IR) code against optimized versions, using symbolic execution and SMT solvers to mathematically prove that transformations preserve program semantics. Key features include automated bug detection in LLVM's optimization passes, support for floating-point and integer operations, and integration into continuous testing pipelines. This tool is primarily used by compiler developers, verification researchers, and software engineers working on safety-critical systems to ensure optimization reliability. By identifying subtle bugs in compiler transformations, Alive2 helps prevent unintended behavior changes that could lead to security vulnerabilities or functional errors in compiled software.
