My team is looking for a way to get around gcov reporting branch coverage for dead/compiler generated code. I noticed that gcovr has an option --exclude-unreachable-branches that seems to do what we need. Also, lcov has the option --no-markers which Ignore[s] exclusion markers in source code.
Do these two options leave the compiler generated "dead code" out of the branch coverage?
Also, I'm wondering,
What is the difference between these two tools?
We currently use lcov, and I know it displays gcov info in a graphical display format.
