Abstract

Describes a tool that takes two versions of a procedure and generates a report summarizing the semantic differences between them. Unlike existing tools based on comparison of program dependence graphs, our tool expresses its results in terms of the observable input-output behaviour of the procedure, rather than its syntactic structure. And because the analysis is truly semantic, it requires no prior matching of syntactic components, and generates fewer spurious differences, so that meaning-preserving transformations (such as renaming local variables) are correctly determined to have no visible effect. A preliminary experiment on modifications applied to the code of a large real-time system suggests that the approach is practical.>

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
