Gcov: Counting lines of source code (untested files) as gcov does

[Fredrik Johansson]

Apparently I forgot to CC this to the list last time, so here is a new attempt!

In that case I guess I wouldn't need any "dummy routine" either, just
include the code from a testfile that I know is beeing run, and I have
one TestMain.cpp or something that loads the testsuit and such. That
would work, wouldn't it? I'm at home now so I don't have the code in
front of me, but an included file that isn't used get 0% coverage,
right?

But anyway, I would really really hate to have to alter the main code
base. I'm hired over the summer to alter the build system, and if I
came and told the other developers to make changes to their other
components I think that would discorage them to use gcov at all, which
is the opposite to what I'm hired to do :)

It's not possible to "trick" gcov (or create a version of gcov that
can be tricked) that there is a .da file but that no lines have been
executed or something like that (the line count is done by reading the
.bb anyway, right?)?

Thanks!
