Leading compiler technology

Built by our experts, the IAR C/C++ Compiler offers advanced and highly targeted optimizations, unleashing the ultimate performance for building the most efficient embedded applications. Paired with the IAR Linker, it can produce ELF/DWARF output images alongside a variety of other industry-standard image formats.

04

Comprehensive debugger

The IAR C-SPY Debugger provides a comprehensive debugging experience. It supports popular probes, including trace, code coverage, function profiling, RTOS awareness plugins, and debugging automation via macros. It also supports multicore targets, including SMP (symmetric multiprocessing) and AMP (asymmetric multiprocessing).

05

Integrated code analysis add-ons

The integrated IAR analysis tools streamline code quality. IAR C-STAT, the static analysis tool, enforces high industrial standards and best practices. IAR C-RUN, the runtime analysis tool, detects preventable runtime errors, taking the debugging experience to the next level.

06

On-demand training included

Immediate access to our online library of training courses tailored for embedded developers licensed to use the IAR technologies, that can be taken at any desired order and pace.

Integrating CMSIS-Toolbox with IAR Embedded Workbench for Arm

Latest releases

We are constantly updating and refining our tools with new features, new device support and extended capabilities.

Latest Version: 9.60.3

  • Improved CMake support

    CMake files can now be directly read by the IAR Embedded Workbench IDE to populate the project manager view, allowing the flexibility of CMake to be mirrored in IAR Embedded Workbench and empowering the user with the IAR C-SPY debug experience as well as building. Enables support for importing, building, and debugging projects based on CMake in IAR Embedded Workbench.

  • Cortex-M52 support
  • C-STAT support for MISRA C:2023

    MISRA C:2023, also known as MISRA C Third Edition, Second Revision, is now supported. It incorporates MISRA C:2012 amendments 2 (AMD2), 3 (AMD3) and 4 (AMD4), plus technical corrigendum 2 (TC2). MISRA C:2023 incorporates support for C11 and C18 language features.

  • New and updated support for GCC’s "Extensions to the C Programming Language"
  • Support for additional GCC relaxations to ISO C
  • Cortex-R52 single precision only mode
  • J-Link: command line debug capability for CI/CD activities and debugging using VS Code on Linux and Windows
    The Segger J-Link debug probe has been added to the C-SPY command line utility (cspybat) and the Runtime Analysis tool (C-RUN) on booth Linux and Windows.
  • Cortex-M55 and Cortex-M85 ETM trace

    The debugger trace decoder now supports full instruction trace on the latest Arm Cortex-M cores.

  • SDM Debug Authentication

    The C-SPY debugger now supports the Arm SDM (Secure Debug Manager) debug authentication method on I-jet, CMSIS-DAP and ST-LINK.

  • Experimental support for Sys V shared objects to dynamically create loadable shared libraries
  • Experimental support for SARIF output

    The SARIF output format is supported by the compiler, linker, assembler and C-STAT command line tools.

  • Support for new devices

Version: 9.40

  • 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.

    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
