the RTEMS project has a covoar tool:

I have seen some reports generated by it, but I never used it myself. I 
have trouble to find out how it works. There is nothing in the 

cd rtems-docs
grep -ri covoar .

There is some documentation available here:

If I invoke the rtems-test like this in the erc32 BSP build directory, I 
get an error:

rtems-test --rtems-bsp=erc32-sis --rtems-tools=/build/rtems/5 --coverage 
--target=sparc-rtems5 .
