Since you mention the -gnatR switch in the latest 3.12
GNAT technology, let me say exactly what this does. For
all named array and record types in the program it gives
the type name, and the representation characteristics.

I must say I am a bit puzzled as to why this does not
give you all the information you want. Here is some sample
output from -gnatR:

Source
------

procedure q is
   type r is record
      a : integer := 0;
      s : string (1 .. 5);
      t : integer;
   end record;
begin
   null;
end q;

Output from -gnatR
------------------

Representation information for unit q
--------------------------------------

for r'Object_Size use 128;
for r use record
   a at  0 range  0 .. 31;
   s at  4 range  0 .. 39;
   t at 12 range  0 .. 31;
end record;
