IAR Embedded Workbench for Renesas RX v4.20.1

Release notes for IAR Embedded Workbench for Renesas RX version 4.20.1
Highlights
C-STAT enhancements
MISRA C:2012 Amendment 1
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.
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 on the CERT C wiki as of January 2020, with the exception of the API, CON, POS, and WIN sections, which are not applicable to IAR Systems 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.
IAR Build Tools for Linux
A new product called IAR Build Tools for Renesas RX has been introduced. It requires a separate product license and is distributed as a Debian package for Ubuntu containing the IAR C/C++ Compiler, IAR Assembler, Linker and library tools, C-STAT, IARBuild, and runtime libraries.
Renesas Smart Configurator update
The Renesas Smart Configurator (included) has been updated to V2.7.0.
