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.

Generate a coverage report named file.cpp.gcov

gcov path/to/file.cppIdentify

Write individual execution counts for every basic block

gcov --all-blocks path/to/file.cppIdentify

Write branch frequencies to the output file and print summary information to stdout as a percentage

gcov --branch-probabilities path/to/file.cppIdentify

Write branch frequencies as the number of branches taken, rather than the percentage

gcov --branch-counts path/to/file.cppIdentify

Do not create a gcov output file

gcov --no-output path/to/file.cppIdentify

Write file level as well as function level summaries

gcov --function-summaries path/to/file.cppIdentify
