Questions tagged [gcov]

gcov is a code coverage tool for GCC

gcov allows you to analyze which parts of a program are not executed. This is interesting for example in order to know which part of a program are not tested. gcov also serves for profiling purposes.

gcov requires additional flags to be passed to GCC in order to generate a special version of a program. This version shouldn't be shipped because it is slower as it generates coverage data files.
