# To produce test coverage reports:
# 1) Build all .o files and executables without optimization and with
# 'COVERAGE=1' on the make command line.
# 2) Run the tests.
# 3) Do 'make coverage'.
# All in one command:
# $ make CFLAGS='-O0' CXXFLAGS='-O0' COVERAGE=1 clean check coverage

# Delete all generated files: executables, object files, test coverage
# reports, etc.

# Run all tests.
# You can run a specific test FOO with the command: 'make check-FOO'.
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.

# link. GNU make's default executable-from-object rule uses $(CC),
# which doesn't include libstdc++, and perhaps does some other things
# wrong as well. Every executable listed in this variable uses the
# pattern rule provided at the bottom, which links all the
# dependencies using $(CXX). Value accumulated throughout the file.

### you can provide your own commands.
