Code coverage analysis and profiling tool that discovers untested parts of a program. Also displays a copy of source code annotated with execution frequencies of code segments. More information:
  • Generate a coverage report named file.cpp.gcov:
    gcov {{path/to/file.cpp}}
  • Write individual execution counts for every basic block:
    gcov --all-blocks {{path/to/file.cpp}}
  • Write branch frequencies to the output file and print summary information to stdout as a percentage:
    gcov --branch-probabilities {{path/to/file.cpp}}
  • Write branch frequencies as the number of branches taken, rather than the percentage:
    gcov --branch-counts {{path/to/file.cpp}}
  • Do not create a gcov output file:
    gcov --no-output {{path/to/file.cpp}}
  • Write file level as well as function level summaries:
    gcov --function-summaries {{path/to/file.cpp}}
