IAR Embedded Workbench for Arm, V.8.20
Released Oct 17

Initial support for the Arm v8-R architecture
This release provides basic supports for the Arm v8-R/Cortex-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.

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.

Updated MISRA C:2004 package in C-STAT
The MISRA C:2004 package in C-STAT has been updated with about 20 new checks, of which some are enabled by default.

Support for new devices from NXP, Realtek, ST and TI
