PC-lint Plus Release Candidate

PC-lint Plus will be released the 4th quarter of 2017 and the first release candidate will be available by September 2017. We will be accepting a limited number of new testers for the Release Candidate. If you are a registered PC-lint/ FlexeLint user and are not currently a beta tester and would like to test the release candidate for PC-lint Plus, please fill out the request form found HERE

What is PC-lint Plus?

PC-lint Plus is a rewrite of PC-lint from the ground up. It combines the clang framework with Gimpel Software’s 30+ years of static analysis experience to provide a product that supports the latest C and C++ standards and implements the leading edge analysis technology that Gimpel Software is known for. While PC-lint Plus is a new offering from Gimpel Software, it is largely backward compatible with PC-lint /FlexeLint. In particular, most of the same options and messages are supported by PC-lint Plus, indirect files work the same way, and flagship features such as Value Tracking, User-defined Function Semantics, and Strong Types are all available and many features have been significantly enhanced.

What’s New in PC-lint Plus

PC-lint Plus includes many new messages, features, and enhancements. The highlights include:

Modern C++ Support

PC-lint Plus fully supports C++11 and C++14 and most of the soon-to-be published C++17 Standard by leveraging clang to perform the lexing and parsing for C and C++ source code. Clang updates are regularly merged into PC-lint Plus ensuring prompt support for the newest language features. As a result, PC-lint Plus supports the latest compilers, including current versions of GCC and clang as well as Visual Studio 2015.

Improved Value Tracking

Value tracking now stores ranges of values instead of just individual values which allows PC-lint Plus to gain further insight into your code when the exact values are unknown but they may be bounded by conditional logic. Structure members and floating point values are also now tracked. Data and function pointers can participate in value tracking which allows PC-lint Plus to provide more effective analysis and a better understanding of aliased values and functions.

Parallel Analysis

PC-lint Plus supports parallel analysis of projects by using separate threads to analyze each source code module, which speeds up the analysis process by making full use of the available hardware.

Streamlined Configuration

A new configuration tool automates the configuration process by extracting information from your compiler and your build process to generate comprehensive and accurate configurations that match the way you build your projects.

Improved MISRA C 2012 Support

PC-lint Plus further extends existing MISRA C 2012 support with new messages, improved message verbiage that more clearly explains the violation being diagnosed, and underlying type breakdowns that show exactly how the different parts of an expression contributed to the ultimate underlying type of the expression to aid in the understanding of messages related to underlying types.

Enhanced Diagnostics

Diagnostic facilities have been greatly improved in PC-lint Plus by providing the precise locations of issues encountered, by highlighting the key constructs referenced in the message, and by the introduction of supplemental messages to provide further insight into the conditions that lead to the issuance of the diagnostic.

Messages can now be organized into user-defined named groups for easier manipulation, parameterized suppressions can be localized to a specific code region, messages can be suppressed using regular expressions, and -efile can now be used to suppress messages within specific files.

Improved Function Semantics

PC-lint Plus provides built-in function semantics for over 200 standard library functions.

Custom return semantics defined with the `-sem` option are now verified when the body of the function is available. For example, a semantic that specifies that a function never returns null will result in a diagnostic if the function actually does ever return null.

User-defined function semantics can also now be specified for individual function overloads and function templates.

Other features

In addition to the new features and enhancements described above, PC-lint Plus contains dozens of minor improvements including a built-in help system, deprecation of types and options, improved printf and scanf format string checking with positional parameter support, the ability to save and restore entire option contexts, improved message verbiage for existing messages, and hundreds of new diagnostics (including many dedicated to the use of new C++ language features).
