@code{gcov} is a test coverage program. Use it in concert with @sc{gnu}
CC to analyze your programs to help create more efficient, faster
@code{gcov} works only on code compiled with @sc{gnu} CC. It is not
compatible with any other profiling or test coverage mechanism.

The execution counts are cumulative. If the example program were

the output does not indicate how many times the result was 0 and how
many times the result was 1.
