IAR Embedded Workbench

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.

Performance analysis

The performance analyzer facility in the hardware debugger can measure a number of execution aspects to help you understand how well your application performs on the MCU. Because performance analysis uses the debugger’s performance measurement circuit to measure the execution time, it does not slow down the execution of your application. The performance analysis is capable of measuring these execution aspects:

• the total number of executed instructions
• the number of executed instructions that trigger branching
• the number of accepted interrupts and other exceptions
• the total number of clock cycles
• the number of clock cycles, excluding the interrupt processing
• the number of cycles in which DI/EI interrupts are disabled
• the number of instruction fetch requests, and instruction cache non-wait responses for instruction fetch requests, issued by the IFU
• the number of flash ROM data requests.

The analysis can cover either the entire execution or execution between two breakpoints. Performance analysis settings cannot be changed during the execution and the results of the analysis are displayed in the Performance Analysis window.

Interrupt logging

Interrupt logging provides you with comprehensive information about the interrupt events. This might be useful for example, to help you locate which interrupts you can fine-tune to become faster. You can log entrances and exits to and from interrupts. You can also log internal interrupt status information, such as triggered, expired, etc. In the IDE:

• The logs are displayed in the Interrupt Log window
• A summary is available in the Interrupt Log Summary window
• The Interrupt graph in the Timeline window provides a graphical view of the interrupt events during the execution of your application.

Flash memory erase

It is now possible to erase all flash memory areas including the data flash area via the menu command Project>Download>Erase memory.

Extended functionality in C-STAT

The static analysis tool C-STAT has been extended with approximately 150 new checks including 90 new MISRA C:2012 checks and two new packages of checks. There are also new options to enable or disable the false-positives elimination phase of the analysis and to exclude files from the analysis. C-STAT message suppression can now be controlled by directives placed in comments in the source files.
