The basic idea is that debug info should be independent of the program
space.  That way, symbol tables can be shared across inferiors.

The project is somewhat documented here:

https://sourceware.org/gdb/wiki/ObjfileSplitting

It's been vaguely ongoing for a very long time.  I managed to implement
it for minsyms, psyms, and line tables; but symbols and blocks have
proven to be more difficult, with a trail of failed branches behind
them.
