Now I've got your use-case and I like it. It's cool one can utilize GCOV
even without a filesystem.
Yes, it basically works quite well. I try to make it a bit easier to
use. What seems to be quite common is that tests for embedded systems
report their test data through an in order character stream, for example
through an UART device. I used this primitive encoding of the gcov
information:

Maybe we could add the file path into the gcov information stream using
a new tag:
#define GCOV_TAG_GCDA_FILE_NAME ((gcov_unsigned_t)0xa5000000)
Then the complete gcov information can be dumped using a single base64
encoded stream. We could add some support to the gcov-tool to read this
stream and merge it into gcda files.
