Control of optimized DLIB library functions

Some of the DLIB libraries delivered with the product now contain optimized variants, such as a small integer division routine for Cortex-M0, or a fast strcpy implementation for cores that support the Thumb-2 ISA. The compiler and linker will automatically select the variant that matches the optimization goal. It is possible to override this selection by using the option --use_optimized_variants. See user guide corrections for more information.

CMSIS-DAP v2

The debugger now supports the latest CMSIS-DAP standard with WinUSB transfer mode resulting in faster debug experiences when using CMSIS-DAP v2 compliant boards.

Support for new devices

Support for new devices from Ambiq, Cypress, Microchip, NXP, Qorvo.

Updated IDE look and feel

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

Support for the C11 language standard

The compiler and libraries add support for the latest C language standard ISO/IEC 9899:2011.

Support for the C++14 language standard

The compiler and libraries now support the latest C++ standard ISO/IEC 14882:2014.

Unicode support

The Unicode standard for consistent encoding, representation, and handling of text is now supported. This means that you can use Unicode characters (alphabetic, numeric, symbols, emoji, etc) in the source code.

Stack usage analysis

With stack usage analysis enabled, a stack usage section will be added to the linker map file with listings of the maximum stack depth for each call graph root. The analysis process can be customized to take into account such constructs as calls via function pointers and recursion. The output can optionally be generated in XML format for post-processing activities.

Stack protection

The IAR C/C++ compiler for RH850 now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection.

Renesas Smart Configurator included

Renesas Smart Configurator is a standalone tool for automatically generating control programs (device driver programs) for peripheral modules in accordance with settings. It fully supports code generation for IAR Embedded Workbench for RH850 and the generated modules are incorporated via the IAR Project Connection mechanism.

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.

C-STAT MISRA C

The MISRA C 2004 package in C-STAT has been updated with about 20 new checks, some of which are enabled by default.

Support for the C11 language standard

The compiler and libraries add support for the latest C language standard ISO/IEC 9899:2011.

Support for the C++14 language standard

The compiler and libraries now support the latest C++ standard ISO/IEC 14882:2014.

Unicode support

The Unicode standard for consistent encoding, representation, and handling of text is now supported. This means that you can use Unicode characters (alphabetic, numeric, symbols, emoji, etc) in the source code.

IDE performance improvements

General improvements of the IDE startup time and overall performance.

E2 emulator support

C-SPY now supports the Renesas E2 Lite on-chip debugging emulator. 

Stack protection

The IAR C/C++ compiler for RX now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection. See the IAR C/C++ Development Guide for more information.

C-STAT MISRA C

The MISRA C:2004 package in C-STAT has been updated with about 20 new checks, some of which are enabled by default. 

Updated user documentation

The Assembler User Guide and IAR C/C++ Development Guide have been updated to reflect the product changes.

Improved multicore support

The multicore implementation has been redesigned. It is now easier to setup and configure multicore debug sessions. The debugger can now more easily cope with startup and sleep scenarios where cores are inactive.

Arm Cortex-M23/-M33 project setup

You can now select secure or non-secure setup in the project options. In previous releases this had to be done using Extra Options.

New CMSIS-Pack implementation

The CMSIS-Pack implementation is now based on the CMSIS-Pack Eclipse plugin from Arm.

Extended support for Arm ACLE

The language support now adds extended support for the Arm ACLE (Arm Compiler Language Extensions)

C++17 features

The compiler adds support for the following C++17 features:

• Over-aligned memory allocation
• Compile-time if
• Portable feature test macros
• Fold expressions for variadic templates
• Inline variables
• Initializers in if and switch statements
• Structured binding declarations
• __has_include

Digital state display for Texas Instruments CC devices

C-SPY can now display digital state information from the device in the Timeline window and the State Log window for the Texas Instruments devices CC1350, CC2650, CC2640R2F and the CC13x2/CC26x2 device family.

New device support

Support for new devices from Cypress, Mindmotion, NXP, Silicon Labs, STMicroelectronics and Toshiba.

Call Graph window

A new Call Graph window has been added. It is browsable and displays all calls made to and from each function from any source file in the active project.
