Highlights

• Cortex-M52 support
  Support for the new Cortex-M52 core based on the ARMv8.1-M architecture with features such as Helium MVE (M-profile Vector Extension) and Low Overhead loops.

• 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"
  The following GCC C language extensions are now supported by the compiler (requires IAR language extensions to be enabled):

  • Additional support for __builtin function calls. If supported by the target core, these calls result in code generation using native instructions; else, they are transformed into library function calls.

  • The attribute visibility is now supported in C.

  • Support for arithmetic on void and function pointers (requires IAR language extensions).

  • The __attribute__((__packed__)) construct can now be placed at the end of enum declarations

• Support for additional GCC relaxations to ISO C
  The following GCC C language extensions are now supported by the compiler (requires IAR language extensions to be enabled):

  • In a function that has the return type void, a return statement can return a void expression. For example return (void)expr; (requires IAR language extensions).

  • The error Pe042 ("operand types are incompatible") is now a soft error in more language constructs. By reducing the severity of this error and the errors Pe144 and Pe513, an application can mix void * and function pointers.

• Cortex-R52 single precision only mode
  The compiler can now be configured to only support Cortex-R52 single precision 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
  Shared objects is a new type of output from the linker. It allows creation of shared libraries that can be dynamically loaded by an application. Use of shared objects requires the use of a dynamic loader/linker or something that can act like a dynamic linker. A dynamic linker can load shared objects into available memory and resolve references to and from them. Dynamic linkers are typically part of an operating system.
  See IAR C/C++ Development Guide for more information. An example can be found in arm\src\sharedobjects.

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