Sorry for digging up this thread, but since this is a recurring change
it appears that the mass rebuild is not enough by itself. As of today
lcov doesn't work with GCC 9.x [1] and it would be nice if either:
- gcc provided an option to use a previous gcov format when a new one
lands (I understand it makes things more complicated)
No, we certainly don't want to diverge from gcc upstream here, and gcc
upstream doesn't have that.
- the Fedora lcov spec would run `make test` in a %check section
lcov maintainers have been told they should use the json intermediate format
from gcov -i instead of trying to parse the binary data.
