I'm sorry, I must be missing something. Why would you want to use
Unchecked_Conversion or some form of overlay for this problem? Why can't
the following function be used (assuming Integer_16 and Integer_32 are
defined with appropriate ranges and 'Sizes?
function Convert (Hi, Lo : Integer_16) return Integer_32 is
Shift_16 : constant Integer_32 := 2**16;
begin
if Lo < 0 then
return Integer_32(Hi) * Shift_16 + (Shift_16 +
Integer_32(Lo));
else
return Integer_32(Hi) * Shift_16 + Integer_32(Lo);
end if;
end Convert;
