I'm not sure what you mean by 'memory map files'.

Do you mean the map that the linker can output, showing where objects in
the link appear in store?

Or perhaps you mean a way of making a file appear as an array of bytes,
so it looks as though it's in memory? (mmap(2)) - in which case, GNAT
provides System.Mmap - look for s-mmap.ads.

Darwin users are be SOL with this (System.Mmap.OS_Interface is missing),
but you should be OK on Linux.

The files that _are_ present recommend looking at
