IAR Embedded Workbench for Renesas SuperH

Complete development toolchain to maximize the performance and minimize the power consumption for SH-2A and SH2A-FPU-based applications.

01

User-friendly IDE

Integrated development environment with project management tools and editor, including automatic checking of MISRA C rules (MISRA-C:2004), configuration files for all devices, linker and library tools, example projects and code templates.

02

Powerful build tools

Included is a highly optimizing C and C++ compiler for SH-2A and SH2A-FPU, runtime libraries and a relocating SH-2A assembler.

03

Comprehensive debugger

C-SPY Debugger comes with a SH-2A simulator, support for RTOS-aware debugging on hardware and debugging system support including Renesas E10A-USB driver, C-SPY Debugger plugin SDK available for 3rd party debuggers and supports various linker output formats for debugging in 3rd party debug systems.

Latest releases

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

Version 2.30

New text editor and source browser

A new text editor and source browser are introduced in this version. The new features include auto completion, parameter hint, code folding, block select, block indent, bracket matching, zoom and word/paragraph navigation. The new source browser adds features like Go to Declaration and Find All References to symbols.

New licensing management system (LMS) introduced

The new LMS used with this release introduces new features like commuter licenses, automatic license activation and support for virtual servers. It is easier to administer and a new single CD concept enables all variants of IAR Embedded Workbench for a certain product to be included in one and the same installer.

Improved optimization

The compiler optimizes for higher execution speed compared to the previous version.

Sampled Graphs in C-SPY

It is now possible to specify variables for which you want to collect data samples. You can view the sampled data either in table format in the Data Sample window or as graphs in the Sampled Graphs window.

Custom SFR window

It is now possible to define custom SFR's (special function registers) in C-SPY with selectable access size and type.

Call Graph window

A new Call Graph window has been added. It is browsable and displays all calls made to and from each function from any source file in the active project.

Macro Quicklaunch window

The new Macro Quicklaunch window makes it possible to evaluate expressions and to launch C-SPY macros. The return value from the evaluated macro or expression is shown in a separate column and the user can re-trigger the evaluation at any given point.

Updated device support and example projects

SFR header files, linker configuration files and device description files have been added for the latest Renesas devices together with various new example projects.

Version 2.20

Improved optimization

The compiler has been improved to optimize for higher execution speed, compared to the previous version. These improvements include options for more aggressive loop unrolling and function inlining.

C-SPY E10A-USB emulator debugger improvements

  • Statistical application profiling based on trace data
  • Support for software breakpoints
  • Possibility to set breakpoints during program execution
  • Improved startup time

Timeline window

A new Timeline window in the simulator allows graphically correlated visualization of call stack and interrupt log plotted against time.

Thread-safe libraries

The DLIB library now has improved support for threaded environments.

Linker improvements

A new option --search directory has been added that searches for object files and libraries in a specified path. A new Migration Guide has also been added describing differences between ELF/DWARF based products with ILINK and UBROF based products with XLINK.

Subversion

The version control integration has been extended with support for Subversion (SVN).

Automatic selection of printf/scanf formatter

The compiler/linker parses the printf/scanf format specifiers and select the smallest possible formatter from the library.

Virtual Function Elimination (VFE)

The compiler/linker optimizes C++ applications and removes unused virtual functions.

Updated device support

Device support has been added for the latest Renesas devices.

User guides and documentation

Languages and standards

The IAR C/C++ compilers offer different dialects of the C and C++ programming languages, as well as different extensions specific for embedded programming (please note that not all language standards are supported for all target implementations). The compiler can be instructed to disable extensions for strict conformance to the standards. 

A wide range of industry-standard debug and image formats compatible with most popular debuggers and emulators are supported. This includes ELF/DWARF where applicable.

ISO/ANSI C/C++ Compliance

The IAR C/C++ compilers adhere to a freestanding implementation of the following C programming language standards:

  • INCITS/ISO/IEC 9899:2018, known as C18 (Latest version only).
  • The compiler supports all C++17 features. The C++ library supports C++14 with no C++17 additions.  (Latest version only).
  • ISO/IEC 14882:2015, known as C++14
  • INCITS/ISO/IEC 9899:2012, known as C11
  • ANSI X3.159-1989, known as C89

The ISO/ANSI C/C++ Compliance level varies between the different compilers. For complete information, please refer to the IAR C/C++ Compiler user documentation in your chosen product.

IEEE 754 standard

IAR Embedded Workbench supports the IEEE 754 standard for floating-point arithmetic.

MISRA C

MISRA C is a software development standard for the C programming language developed by MISRA, The Motor Industry Software Reliability Association. Its aims are to facilitate code safety, portability and reliability in the context of embedded systems, specifically those systems programmed in ISO C.

The first edition of the MISRA C standard, "Guidelines for the use of the C language in vehicle based software", was produced in 1998. In 2004, a second edition was produced with many substantial changes to the guidelines, including a complete renumbering of the rules. Additionally MISRA C:2012 with extended support and MISRA C++:2008 for identifying unsafe code constructs in the C++ standard have also been added to the standards.

IAR Embedded Workbench features an add-on product C-STAT so you can check compliance with rules as defined by MISRA C:2004, MISRA C++:2008 and MISRA C:2012.

Test validation

We use the following commercial test suites to test conformance of our tools to the standards:

  • Plum Hall Validation test suite for ISO/IEC C conformance
  • Perennial EC++ Validation Suite for C++ conformance
  • Dinkum C++ Proofer to test how our libraries conform to the C and C++ standard as well as test our STL implementation against the C++ standard.

In addition to the commercial suites, we use several in-house test suites for testing new features, regression testing, corrected errors, etc.
