After doing make clean, you can build coverage measuring ready ctags by make COVERAGE=1. At this time *.gcno files are generated by the compiler. *.gcno files can be removed with make clean.

After building ctags, you can run run-gcov target. When running *.gcda files. The target runs ctags withh all input files under Units/**/input.*; and call gcov. Human readable result is printed. The detail can be shown in *.gcov. files. *.gcda files and *.gcov files can be removed with make clean-gcov.
