Question about -mo compiler option for C64+ dsp (code gen tools 6.0.8)

Hi All,

    There is a question about -mo compiler option.  The -mo compiler option  placed each function in a file in its own subsection.

  Thus, only the functions that are referenced in the application are linked into the final executable. just now I do a test to confirm the conclusion. In the test project, The demo project dependes on another lib project, and the lib project choosed the -mo compiler option.when I checked the map file，the fuctions that are not referenced in the application also are linked into the final executable. So I was so confuesd, and I want to  know, why? and  How to use the -mo option correctly?

  Compiler version 6.0.8 for c6000 DSP.

BR,

Robert

    Hi Robert,

    That should not be happening.

    First thing I would recommend it to update to the latest Code Generation tools just to make sure it is not a bug (I do not remember any bugs related to the -mo option). If updating does not work, then please attach a test case and I can take a look for you.

    The application code has to be built with -mo as well.

    When the linker sees an object module file.obj, and all of the sections in that module were built without -mo, then the linker keeps every section from file.obj, regardless of whether those file.obj sections are ever referenced.

    Thanks and regards,
