It could be converted into a function returning bool, a la

    if (!loop_rc_processing(...))
        break;

but then the burden is on you to show there's negligible performance
impact, a question that doesn't arise when just macro-izing existing
code.  I suppose the function could be made inline, but then we're
right back to the question of how well lcov will display the actual
code coverage.
