files" menus, which executes gcov automatically.
This script will also perform checks along the way to guide through the
procedure of obtaining gcov info.
The output of the gcov process is displayed in a separate console.
At the end of the processing, the open editors are decorated with coverage
information.
Note that GPS calls gcov so that the .gcov files are generated
- in the directory pointed to by the "GCOV_ROOT" environment variable, or
- in the object directory of the root project, if this variable is not set
