Is there any macro defined when compiling with --coverage option?

As mentioned by the title, I would like to achieve something like this:

void my_exit(int status)
{
#ifdef _GCOV
   __gcov_flush();
#endif
   _exit(status);
}

But I do not know if there is a _GCOV（or something similar） defined when compiling with --coverage. Any idea will be appreciated!

Solution

  • Doesn't seem to be:

    $ true | gcc -E - -dM > no-coverage.h
$ true | gcc -E - -dM --coverage > coverage.h
$ diff no-coverage.h coverage.h
