Options (5)

-a, --all-blocksboolean

Write individual execution counts for every basic block

Example: gcov {{[-a|--all-blocks]}} {{path/to/file.cpp}}

-b, --branch-probabilitiesboolean

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

Example: gcov {{[-b|--branch-probabilities]}} {{path/to/file.cpp}}

-c, --branch-countsboolean

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

Example: gcov {{[-c|--branch-counts]}} {{path/to/file.cpp}}

-n, --no-outputboolean

Do not create a `gcov` output file

Example: gcov {{[-n|--no-output]}} {{path/to/file.cpp}}

-f, --function-summariesboolean

Write file level as well as function level summaries

Example: gcov {{[-f|--function-summaries]}} {{path/to/file.cpp}}
