This can be used to remove any stale coverage data before any
particular test run. This is useful for analysing individual tests.

``gcov`` is a GCC tool to analyze the testing coverage by
instrumenting the tested code. To use it, configure QEMU with
``--enable-gcov`` option and build. Then run ``make check`` as usual.
Reports can be obtained by running ``gcov`` command on the output
files under ``$build_dir/tests/``, please read the ``gcov``
documentation for more information.
If you want to gather coverage information on a single test the ``make
clean-coverage`` target can be used to delete any existing coverage
information before running a single test.
Reports can be obtained by running ``gcov`` command
on the output files under ``$build_dir/tests/``, please read the
``gcov`` documentation for more information.
