# 1) Build all .o files and executables without optimization and with
# 'COVERAGE=1' on the make command line.

# 3) Do 'make coverage'.
# All in one command:
# $ make CFLAGS='-O0' CXXFLAGS='-O0' COVERAGE=1 clean check coverage

check:
# Generate coverage reports for the execution that has taken place
# since the coverage data files were last deleted. Only files that
# have been added to COVERAGE_SOURCES (see below) get reported on.
coverage:
# Reset all coverage counts. When coverage is enabled, each time you
# run the program, it adds its execution counts into the profiling
# data files in the build directory. 'make coverage-reset' deletes
# those files, so the counts reported by 'make coverage' start from
# zero again. Note that 'make clean' does this automatically.
