Yeah, the case of Ada is a bit particular, because the entry point
and the main procedures are completely distinct. There is no way that
the *compiler* knows whether one procedure is going to be the "main"
or not for a given program. In fact, the same unit, compiled once,
can be used as the main in one program, and as a simple procedure
that you call in another program. Because of that, I'm not sure
that a DWARF-based solution to encoding the name of the main procedure
is practical.
