This is a question for the gcc mailing list rather than the binutils 
mailing list:

	gcc@gcc.gnu.org

The answer to your question is that you need a more up-to-date version 
of GCC.  ie one that supports GCOV for the ARM.  The current sources in 
the mainline of the GCC CVS repository have this support.  Various 
official releases of the gcc compiler may also have it but I have not 
tested them.

Cheers
