IAR Systems, a future-proof supplier of software tools and services for embedded development, announces the availability of a major update of its development tools for Renesas RX.

Release notes for IAR Embedded Workbench for Renesas RX version 4.12.1 - Released June 19, 2019:

RX66T-H and RX72T support
The RX66T-H and RX72T families based on Renesas third-generation 32-bit RX CPU core (RXv3) are now supported. This includes support for the following new device features:
  • Arithmetic unit for trigonometric functions (TFU) that handles the calculation of sines, cosines, arctangents, and sqrt(x2 + y2) directly in hardware.
  • Register-saving banks and instructions for fast saving and restoring of CPU registers in interrupt handlers.
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.
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.
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 IAR Embedded Workbench IDE Project Management and Building Guide, IAR C/C++ Development Guide and C-SPY Debugging Guide have been updated to reflect the product changes.
