C18 support

The default Standard C is now C18 (ISO/IEC 9899:2018).

C++17 support

The compiler now supports all C++17 features. The C++ library supports C++14 with no C++17 additions.

Streaming trace for improved code coverage and profiling features

The code coverage and profiling windows in C-SPY can now be feed with streaming trace data when using the IAR I-jet Trace probes. This means that both code coverage and profiling data can be collected during infinite test runs. See IAR Embedded Workbench C-SPY Debugging Guide for more information.

Extended multicore support

The multicore support has been extended to support any number of asymmetrical cores. For example, it is now possible to debug and control a device with one A9, one M7, and two M4 cores, all synchronized by the Arm Coresight CTI mechanism under debugger control.

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

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.

CMSIS-Pack .gpdsc

The CMSIS-Pack Manager now supports Generator Package Description Files (.gpdsc).

Performance Monitoring window

The Performance Monitoring window is a viewer for counting events or CPU clock cycles through the Performance Monitoring Unit (PMU) available on Cortex A and Cortex R processors. This feature is only available when using an IAR I-jet probe. Live update is available on all recent Cortex-A cores. See IAR Embedded Workbench C-SPY Debugging Guide for more information.

Indicator for sleep mode

A new window in the C-SPY debugger shows if the processor is sleeping or not. See IAR Embedded Workbench C-SPY Debugging Guide for more information.

C-SPY plugin for the UNISON RTOS

The REMEDY RTOS Viewer from RoweBots is now included as a C-SPY plugin. It provides updated information on operating system objects and system state information for the UNISON RTOS.

Support for new devices

This version adds support for new devices from Analog Devices, STMicroelectronics and Toshiba.
