GCOV for multi-threaded applications

Question

Can gcov be used to test multi-threaded application coverage?

I installed some trivial tests of our code base, but it would be nice to have an idea of ​​the coverage that we are achieving. If gcov is not suitable, someone might recommend an alternative tool (possibly an oprofile), ideally with good documentation at startup.

Answer 1

Of course, we used gcov to get coverage information for our multi-threaded application.

You want to compile with gcc 4.3, which can perform dynamic code coverage.
