--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Ok, I can confirm that line directives are accepted, however gcov does not
respect filename of the directives.

Second issue is that calling gcov example.in, actually loads example.gcno file,
where it's written that it's note file for example.f90 (compiled file). Maybe
we can show error message when an argument of gcov does not reflect to a file
mentioned in the note file.

Anyhow, I'm planning to discuss that with Honza and return to that for GCC 8.
