Query: Reasoning About LLVM Code Using Codewalker   This paper reports on initial experiments using J Moore's Codewalker to
reason about programs compiled to the Low-Level Virtual Machine (LLVM)
intermediate form. Previously, we reported on a translator from LLVM to the
applicative subset of Common Lisp accepted by the ACL2 theorem prover,
producing executable ACL2 formal models, and allowing us to both prove theorems
about the translated models as well as validate those models by testing. That
translator provided many of the benefits of a pure decompilation into logic
approach, but had the disadvantage of not being verified. The availability of
Codewalker as of ACL2 7.0 has provided an opportunity to revisit this idea, and
employ a more trustworthy decompilation into logic tool. Thus, we have employed
the Codewalker method to create an interpreter for a subset of the LLVM
instruction set, and have used Codewalker to analyze some simple array-based C
programs compiled to LLVM form. We discuss advantages and limitations of the
Codewalker-based method compared to the previous method, and provide some
challenge problems for future Codewalker development.
