Evaluating Value-Graph Translation Validation for LLVM

Free registration required

Executive Summary

Translation validators are static analyzers that attempt to verify that program transformations preserve semantics. Normalizing translation validators do so by trying to match the value-graphs of an original function and it's transformed counterpart. In this paper, the authors present the design of such a validator for LLVM's intra-procedural optimizations, a design that does not require any instrumentation of the optimizer, nor any rewriting of the source code to compile, and needs to run only once to validate a pipeline of optimizations. They present the results of their preliminary experiments on a set of benchmarks that include GCC, a perl interpreter, sqlite3, and other C programs.
