Quite strange to see such a concern here, in Ada (not C or Assembler) forum.
Why do you need global addresses of these bytes? It is a compiler's job and
not a concern for an application programmer. Well, I hope you aren't imagining
Petabytes+ single data item, string or BLOB -:)

No, there is no need to fetch bunches of memory - compiler will tell (perhaps
through OS directives) the memory chip siutable value of "base" and it's enough
- we went through that long ago. Naturally, that will be less efficient than
we currently associate with "real" (that is, non-virtual) memory - the switches
of the "base" will take time, but it will be more efficient than disk I/O.
