CodePeer 2.3 is the most advanced static analysis tool available for Ada – now integrating Ada 2012's contract-based programming capabilities. CodePeer detects errors before they grow into expensive problems. Serving as an efficient and accurate code reviewer, CodePeer identifies constructs that are likely to lead to run-time errors such as buffer overflows. And it flags legal but suspect code, typical of logic errors. Going well beyond the capabilities of typical static analysis tools, CodePeer also produces a detailed analysis of each subprogram, including pre- and post-conditions. Such an analysis makes it easier to find potential bugs and vulnerabilities early: if the implicit specification deduced by CodePeer does not match the component’s requirements, a reviewer is alerted immediately to a likely logic error. During system development, CodePeer can help prevent errors from being introduced, and it can also be used as part of a systematic code review process to dramatically increase the efficiency of human review. Furthermore, CodePeer can be used retrospectively on existing code, to detect and remove latent bugs.
