IAR Embedded Workbench for Arm, V8.50 Released Feb 17

Extended coverage of CERT C

The static analysis tool C-STAT has extended its coverage of the SEI CERT C Coding Standard. The SEI CERT C Coding Standard's goal is to provide rules for developing safe, reliable and secure systems in the C programming language, with support for C11 constructs. C-STAT covers all rules in the different CERT C sections listed at the CERT C wiki as of January 2020, with the exception of the API, CON, POS and WIN sections which are not applicable to our products, yielding a total of 90 covered rules.

Link analysis trace information

The link analysis messages now display trace information when relevant. For checks looking for conflicting symbol names, all conflicting declarations are now listed in the trace information instead of each pair of conflicts being described in a separate message. This might lead to fewer reported messages for the same number of found issues.

Support for new devices

Updated IDE look and feel

The IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials.

Enhanced Registers and Symbols windows in C-SPY

The C-SPY Symbols and Registers windows have been re-designed with new features. The Symbols window now has a filtering function and a new column displaying to which program module a certain symbol belongs. Some of the new features in the Registers window are drag-and-drop support from source code windows, detailed register tool-tip information, and improved handling of user-defined registers groups.

Improved C-STAT Static analysis

  • New checks have been added including about 20 new checks in the MISRA C 2004 package.
  • Improved analysis engine which increases the analysis precision.
  • The time-consuming false-positive analysis is now disabled by default but can be enabled by an option in the IAR Embedded Workbench IDE or on the command line.
  • A new option in the IAR Embedded Workbench IDE makes it possible to limit the number of messages generated per check and per file.
  • C-STAT message suppression can now be controlled by directives placed in comments in the source files.
  • A new option --deterministic has been added to ensure a deterministic amount of messages when running icstat with multiple threads, so that the amount of messages stays approximately the same from one analysis run to another. This option puts a limit on the option --parallel.

Updated user documentation

The IDE Project Management and Building Guide has been updated to reflect the product changes.
