Highlights

• Parallel build
  IAR Embedded Workbench can now build projects using multiple parallel processes. This can improve build performance significantly on multi-core or multiple processor computers. To control parallel build, choose Tools>Options>Project>Enable parallel build.
• 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.
• Saving C-SPY Watch window content
  In the C-SPY Watch window family, you can now choose Save All to File from the context menu to save the contents of the current window to a text file.
• New windows for C-SPY macros
  Three new C-SPY windows have been added to easier manage C-SPY macros. The Macro Registration window controls which macro files are loaded and the Debugger Macros window shows a list of all macros available in the debugger. The Macro Quicklaunch window makes it possible to evaluate expressions and to launch C-SPY macros.
• Project connection
  Files or file packages generated by external code generation tools can be imported and IAR Embedded Workbench automatically detects changes in the generated file set. This enables automated integration with for example device configuration tools.
• External analyzers
  A flexible mechanism to invoke external analyzers for project files. This is typically used as an interface to static analysis tools like PC-lint.
• Custom argument variables
  Custom argument variables can be used in the IAR Embedded Workbench IDE whenever there is a need for a macro-like expansion that depends on the current context. This could for example be in arguments to an external build tool.
• 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.
• Save as for project workspaces
  It is now possible in the IDE to save a project workspace with a new name.
• Updated user documentation
  The C-SPY Debugging Guide has been updated to reflect the product changes.

Important information

• Upgrade information
• Before you install
  

  To avoid any problems, do not install this release in a directory where you have previously installed any older version of IAR Embedded Workbench. It is recommended that you either uninstall an earlier product, or install this release in a separate directory. As before, however, it is possible to install different products, all using the same version of the main application, in the same root directory.

• License renewal
  

  The upgrade to this version might require a license renewal. This is performed by starting the IAR License Manager and selecting License>Check for License Renewal.
  Note, if you have a network license, this must be performed on the license server.

• Microsoft Windows
  

  Windows Vista and newer operating systems have a security mechanism called UAC (User Access Control). Disabling UAC will automatically grant you permission when a task requires administrative rights but this is not recommended because it will reduce the security of the computer. It is not necessary to run the IAR Embedded Workbench IDE as an administrator. However, if you are not, modifications to the installed product tree in C:\Program Files\IAR Systems might not work as intended and could give unexpected results. One example is opening and building projects directly from the installed product tree. The build will succeed, but the resulting files (object, list, ...) will not appear where expected. Instead all output files will be redirected by the OS to C:\Users\\AppData\Local\VirtualStore\Program Files\IAR Systems. To avoid this, the preferred way is to copy the examples to a location outside Program Files, either manually or automatically by opening them via the IAR Information Center.

• Because of important differences in architecture between the 78K0 and 78K0S microcontroller cores and the 78K0R microcontroller core, IAR Embedded Workbench for Renesas 78K includes two separate compilers and assemblers for 78K0/78K0S and 78K0R respectively.
• The latest device files, emulator firmware and other software updates from Renesas can be found here.
• If you are migrating from V3.xx or from Renesas tools to this version, read the 78K IAR Migration Guide for detailed information.
• After installation, the compiler must be run with administrator privileges at least once before a non-privileged user can run the compiler.
