IAR Embedded Workbench for Arm Cortex-M

• IDE Build Actions improvements
  Build actions are a flexible design, to which you can inject and chain commands as part of the build. Build actions will replace the previous pre- and post-build actions with a more intuitive mechanism, to which multiple actions can be executed before compilation and before/after linking.

• Arm PACBTI support
  Implements the pointer authentication security mechanism initially launched in the Arm Cortex-M85 core.

• Arm Cortex-A32 support
  Adds support for the Arm Cortex-A32 32-bit core based on the Armv8-A AARCH32 architecture.

• New compiler GCC extensions
  The following GCC extensions are now supported by the compiler

  • the __auto_type specifier

  • the format function attribute

  • the warn_unused_result function attribute

• Renesas E2/E2 Lite emulator support
  The Renesas E2 emulator is an advanced on-chip debugging emulator that is now natively supported in IAR Embedded Workbench for Arm.

• Renesas RA Smart Configurator support for the IAR I-jet debug probe
  For devices that support TrustZone, you can use the Renesas Device Partition Manager (RDPM) in the RA Smart Configurator to check and change the state of the device lifecycle management (DLM), make the memory partition settings, and restore the state of the device. The necessary I-jet driver is distributed as part of the RA Smart Configurator.

• Support for new devices

• Arm Cortex-R82 support
  Support for the new high performance 64-bit Cortex-R82 core based on the ARMv8-R AARch64 architecture.

• Support for the ST STLINK-V3PWR debug probe (Service Pack v9.32.2)
  Adds full power measurement capabilities when debugging using the ST STLINK-V3PWR probe. Power data can be visualized using the debugger Timeline and Power Log windows. Power statistics are collected and displayed by the debugger Function Profiler.

• Support for new devices

• Arm Cortex-M85 support
• Arm Cortex-M Custom Instructions support
• Cortex-R52+ support
• Extended Armv8-A support
• Library support for the C++17 language standard
• Additional GNU C language extensions
• Editor and IDE enhancements
• Visual Studio Code support
  The IAR Build and IAR C-SPY Debug extensions available on Microsoft Marketplace enable you to work in Visual Studio Code (with IAR Embedded Workbench installed) to:
  - Build IAR Embedded Workbench projects
  - Run the C-STAT static analysis tool
  - Debug applications using the same range of hardware/debug probes as in IAR Embedded Workbench
• Supported devices

Arm Cortex-M55 support

Support for the new Cortex-M55 core based on the ARMv8.1-M architecture with features such as MVE (the Helium M-profile Vector Extension) and Low Overhead loops.

IDE Editor updates

• Editor themes - a new way to set up the colors and fonts in the text editor
• Syntax feedback - instant syntax suggestions while typing
• Improved parameter hints

Additional GNU C language extensions

• pure and const function attributes
• GNU style statement expressions
• GNU style case ranges
• GNU style designated initializer ranges
• Binary literals with a 0b prefix
