Hello,
I reviewed a bit how the code coverage information is produced by GCC
and what libgcov does. I think if we want to use GCOV in RTEMS to get
code coverage in all system states, then we need some tweaks in GCC:

The linker set based gcov information registration is already included
in GCC:

There is a discussion about how the gcov information can be
transferred from the embedded system to the host:
