Highlights
Initial support for the Arm v8-R architecture
This release provides basic supports for the Arm v8-R/R52 architecture.
Stack protection
The IAR C/C++ compiler for Arm 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 IAR C/C++ Development Guide for more information.
Fault exception viewer
The Fault exception viewer is a new debugger window that provides useful information about the cause of a fault exception. It lists the peripheral registers in the System Control Block (SCB) that control fault exceptions and provide information of their cause. All Cortex-M processors have a fault exception mechanism included and is therefore supported by this new feature. See IAR Embedded Workbench C-SPY Debugging Guide for more information.
C-STAT MISRA C
The MISRA C 2004 package in C-STAT has been updated with about 20 new checks, of which some are enabled by default.
