The Renesas Smart Configurator (included) has been updated to V2.7.0.
When using position-independent code and ROPI, the compiler in IAR Embedded Workbench for RH850 will generate code that uses PC-relative references for addressing code and read-only data.
The device support files have been updated to the most recent version from Renesas.
The C/C++ Development Guide, and IDE Project Management and Building Guide have been updated to reflect the product changes.
The Static analysis tool C-STAT has extended its coverage of the MISRA C:2012 Coding Standard and now fully supports MISRA C:2012 Amendment 1. This Amendment adds 14 additional rules to MISRA C:2012 with a focus on security concerns highlighted by the ISO C Secure Guidelines. Several of these address specific issues pertaining to the use of untrustworthy data, a well-known security vulnerability.
The following devices from GigaDevice are now supported: GD32VF103C4T6, GD32VF103C6T6, GD32VF103C8T6, GD32VF103CBT6, GD32VF103R4T6, GD32VF103R6T6, GD32VF103R8T6, GD32VF103RBT6, GD32VF103T4U6, GD32VF103T6U6, GD32VF103T8U6, GD32VF103TBU6, GD32VF103V8T6, GD32VF103VBT6
Highlights

Several reported issues have been fixed. See release notes of individual components for details.
Highlights
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.
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.
C18 support
The default Standard C is now C18 (ISO/IEC 9899:2018).
C++17 support
The compiler now supports almost all C++17 features. The C++ library supports C++14 with no C++17 additions.
Improved Source Browser
The following improvements have been made to the Source Browser:
The source browser data is generated faster as it is now running as a separate thread.
New Source Browser Log window.
Status indicator in the status bar.
Enhanced feedback in case source browsing data cannot be generated.
EZ-CUBE2 On-Chip Debug Emulator support
The EZ-CUBE2 On-Chip Debug Emulator, primarily targeted for the Chinese market, is now supported.
E2 emulator power debugging in C-SPY
The E2 emulator allows you to measure the dynamically changing current drawn by the user system. This is visualized as a graph in the C-SPY Timeline window as well as a list of time-current value pairs in the Power Log window. It is also possible to stop execution when the current goes above or below a certain user-defined threshold value.
Documentation Comments support in the editor
The editor can distinguish comments that start with /**, /*!, /// or //! as Documentation Comments. Inside a Documentation Comment, the editor can recognize keywords that begin with \ or @. If the keyword is recognized as a doxygen keyword, the Documentation Comment will appear in tooltips and parameter hints for variables and functions. See IAR Embedded Workbench IDE Project Management and Building Guide for more information.
Updated user documentation
The IDE Project Management and Building Guide, C-SPY Debugging Guide and C/C++ Development Guide have been updated to reflect the product changes.
