Fix Polyspace Compilation Errors Related to TASKING Compiler

If you choose tasking for the option Compiler (-compiler), you can encounter this issue.

Issue

During Polyspace® analysis, you see an error related to a Special Function Register data type.

Cause

When compiling with the TASKING compiler, you typically use the following compiler flags to specify where Special Function Register (SFR) data types are declared:

  • --cpu=xxx: The compiler implicitly #includes the file sfr/regxxx.sfr in your source files. Once #include-ed, you can use Special Function Registers (SFR-s) declared in that .sfr file.

  • --alternative-sfr-file: The compiler uses an alternative SFR file instead of the regular SFR file. You can use Special Function Registers (SFR-s) declared in that alternative SFR file.

If you specify the TASKING compiler for your Polyspace analysis, the analysis makes the following assumptions about these compiler flags:

  • --cpu=xxx: The analysis chooses a specific value of xxx. If you use a different value with your TASKING compiler, you can encounter an error during Polyspace analysis.

    The xxx value that the Polyspace analysis uses depends on your choice of Target processor type (-target):

    • tricore: tc1793b

    • c166: xc167ci

    • rh850: r7f701603

    • arm: ARMv7M

  • --alternative-sfr-file: The analysis assumes that you do not use an alternative SFR file. If you use one, you can encounter an error.

Solution

Use the command-line option -compiler-parameter in your Polyspace analysis as follows. You use this command-line option to make Polyspace aware of your compiler flags. In the user interface, you can enter the command-line option in the field Other. You can enter the option multiple times.

  • --cpu=xxx: For your Polyspace analysis, use

    -compiler-parameter --cpu=xxx
    Here, xxx is the value that you use when compiling with your compiler.

  • --alternative-sfr-file: For your Polyspace analysis, use

    -compiler-parameter --alternative-sfr-file

    If you still encounter an error because Polyspace is not able to locate your .asfr file, explicitly #include your .asfr file in the preprocessed code using the option Include (-include).

    Typically, the path to the file is Tasking_C166_INSTALL_DIR\include\sfr\regCPUNAME.asfr. For instance, if your TASKING compiler is installed in C:\Program Files\Tasking\C166-VX_v4.0r1\ and you use the CPU-related flag -Cxc2287m_104f or --cpu=xc2287m_104f, the path is C:\Program Files\Tasking\C166-VX_v4.0r1\include\sfr\regxc2287m.asfr.

    You can also encounter the same issue with alternative sfr files when you trace your build command. For more information, see Requirements for Project Creation from Build Systems.
