Evaluating value-graph translation validation for LLVM. Paper presented at ACM SIGPLAN Conference on Programming and Language Design Implementation, June 4-8, 2011, San Jose, California.http://nrs.harvard.edu/urn-3:HUL.InstRepos:4762396Translation validators are static analyzers that attempt to verify that program transformations preserve semantics. Normalizing trans- lation validators do so by trying to match the value-graphs of an original function and its transformed counterpart. In this paper, we 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. We present the results of our preliminary experiments on a set of bench- marks that include GCC, a perl interpreter, SQLite3, and other C programs.en-USalgorithmslanguagesreliabilitytheoryverificationtranslation validationsymbolic evaluationLLVMoptimizationsemantics of programming languagesalgebraic approaches to semanticslogics and meanings of programsspecifying and verifying and reasoning about programsmechanical verificationstudies of program constructsprogram and recursion schemesConference Paper2011-03-22
