This confuses two totally different issues.  1. routine packing per
code module and 2. DLLs.  In the case of 2, Ada compilers (certainly
ObjectAda and GNAT) can build DLLs so this is just irrelevant.  As for
1., that sounds like a design issue.

Another thing that might be lurking in the background is true
incrementally linked modules/routines, where new bits are linked in
dynamically as new references are generated on the fly.  In most
scenarios, this is only plausible with true dynamic languages, in
certain other cases it is a quality of service issue of the OS.
