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. http://en.cnki.com.cn/Article_en/CJFDTOTAL-JSJY200412033.htm ). hth, -- Holger Blasum (SYSGO AG)
