gcov

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: <https://gcc.gnu.org/onlinedocs/gcc/Invoking-Gcov.html>.

  • 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
