Marin asks

<<    There appears to be no way of controlling the link map using the
    GNAT linker. (I did not recall seeing anything about an option to
    even print out the link map.) Is there any way of using the linker
    to control the addresses at which things fall? (Yes, I know Ada
    gives you an address clause for fixing things in memory. However,
    I have often failed to get the desired results using address
    clauses and there are times when it would be much more handy to
    use the linker to do this.)
 
    Also, I did not see any provisions for outputting a symbol table
    or for specifying a load image format other than the default host
    system format. (Motorola S-records, maybe?)

There is no such thing as "the GNAT linker", GNAT uses one of the standard
system linkers that are around, and has the capabilities you want if and
only if this linker has these capabilities. It is also quite straightforward
to change which linker you are using if necessary. But anyway, GNAT is using
standard system capabilities. When it comes to linking, if C can do it, then
so can GNAT.
