be very convenient to help maintaining ABI compatibility in EPEL packages.
That would be a nice tool, but how would it help EPEL? It would rather
help creating a clone of RHEL, for example CentOS and verify that the
rebuild is still providing the same ABI.
For creating such a tool the nearest you could get would be to simply
dump and sort the symbols including function signatures if available
and compare them. But C does not encode arguments to functions into
the symbols so large part of the ABI information is implicit. But at
least you would get part of the ABI to check.
