Sharing generic bodies across instantiations.

["Peter C. Chapin" <pcc482719@gmail.com>]

It has been my understanding that Ada's generics are designed in such a
way as to allow implementations to share the code of a generic body
across all the instantiations. I understand that doing this might
involve a performance penalty relative to creating independent code for
each instantiation. However, I can see that there are cases where such
sharing would be desirable.

Is my understanding still accurate (was it ever accurate), for example
even with Ada 2005?

Thanks!
