STM8AL31E8A
STM8AL3LE89
STM8AL3LE8A

Version 2.20.1

C-STAT
The add-on product C-STAT for static analysis is now supported. C-STAT features innovative static analysis that can detect defects, bugs, and security vulnerabilities as defined by CERT and the Common Weakness Enumeration, as well as help keeping code compliant to coding standards like MISRA C:2012/2004 or MISRA C++:2008. For more information, see the C-STAT Static Analysis Guide.
Parallel build
IAR Embedded Workbench can now build projects using multiple parallel processes. This can improve build performance significantly on multi-core or multiple-processor computers. To enable parallel build, select Tools>Options>Project>Enable parallel build.
Improved code generation and optimization
The compiler generates smaller and faster code for certain source program constructions.
Eclipse support
An Eclipse plugin is now available that allow the IAR C/C++ Compiler, Assembler and Linker to be run from within Eclipse. For more information and a download link, see www.iar.com.
Updated device support
SFR header files, linker configuration files, and device description files have been added for the latest STM8 devices.
Updated user documentation
The IDE Project Management and Building Guide has been updated to reflect the product changes.

Important information

Upgrade information

Before you install

To avoid any problems, do not install this release in a directory where you have previously installed any older version of IAR Embedded Workbench. It is recommended that you either uninstall an earlier product, or install this release in a separate directory. As before, however, it is possible to install different products, all using the same version of the main application, in the same root directory.
License renewal

The upgrade to this version might require a license renewal. This is performed by starting the IAR License Manager and selecting License>Check for License Renewal.
Note, if you have a network license, this must be performed on the license server.

Microsoft Windows

Windows Vista and newer operating systems have a security mechanism called UAC (User Access Control). Disabling UAC will automatically grant you permission when a task requires administrative rights but this is not recommended because it will reduce the security of the computer. It is not necessary to run the IAR Embedded Workbench IDE as an administrator. However, if you are not, modifications to the installed product tree in C:\Program Files\IAR Systems might not work as intended and could give unexpected results. One example is opening and building projects directly from the installed product tree. The build will succeed, but the resulting files (object, list, ...) will not appear where expected. Instead all output files will be redirected by the OS to C:\Users\\AppData\Local\VirtualStore\Program Files\IAR Systems. To avoid this, the preferred way is to copy the examples to a location outside Program Files, either manually or automatically by opening them via the IAR Information Center.
