About gcov_write_summary: it should be also dumped in order to have
a complete .gcda file, right?
How can I get access to the summary information? Here it is not
available:
You only need to change gcov_write_summary in gcov-io.c.
Sorry, I still don't know how I can get the summary information if I
only have a pointer to the gcov_info structure which does not contain
a summary member.
You're right, sorry! But in your case, it will be simple to re-created
it by the script at a host system.
gcov_write_summary (gcov_unsigned_t tag, const struct gcov_summary
*summary)
{
gcov_write_tag_length (tag, GCOV_TAG_SUMMARY_LENGTH);
gcov_write_unsigned (summary->runs);
gcov_write_unsigned (summary->sum_max);
}
Where summary->runs will be 1 and sum_max is maximum counter during the
run.
This __gcov_info_to_gcda() is just a low-level piece which is necessary
to get the gcda stream from an embedded system to a host without having
to know the details of gcov. In follow up patches we could think about a
standard format to serialize the gcda stream. For this format we could
add support to the host gcov tools. One of the tools could read this
stream and output proper *.gcda files.
