title: Generating empty .gcda files
body: <p>I use gcov for doing code coverage analysis with lcov for generating graphical output of coverage. This works well for code file where atleast some part of object file has been executed. I want to be able to track files which have not been executed at all. I suspect this has to do with .gcda files not being generated for these files. Is there a way to force the generation of .gcda file for all object files irrespective of execution?</p>
