Exclusion markers for gcov

I'm using gcov to measure coverage in my C++ code. I'd like to be able to mark certain lines of source code so that they are excluded from coverage reporting when using gcovr. I know they exist because I stumbled across them once but now I can't find where I saw them.

I'm not using lcov to report coverage so references to such markers are no good to me.

Can anyone point me to the right place?

Solution

  • I figured this out finally. The lcov exclusion markers are valid with gcovr.

    The following markers are recognized by geninfo:

    • LCOV_EXCL_LINE
      • Lines containing this marker will be excluded.
    • LCOV_EXCL_START
      • Marks the beginning of an excluded section. The current line is part of this section.
    • LCOV_EXCL_STOP
      • Marks the end of an excluded section. The current line not part of this section.

    You can also replace 'LCOV' above with 'GCOV' or 'GCOVR'. They all work.
