Iirc the gcc approach is instrumenting the basic blocks *before* assembly
generation. Nonetheless, the data format evaluated by gcov could also
be generated by instrumentation of assembly. At least some people 
had academically experimented into that direction (Fei Xun, 
Luo Lei, 2004, "Implementation of assembler program 
coverage testing with GNU tool", Computer Applications,
ISSN 1001-9801, e.g.
