Subject: Ada95: at clause - 'Address
Date: 1996/10/18
Date: 1996-10-18T00:00:00+00:00 [thread overview]
Message-ID: <3267958B.41C6@erols.com> (raw)
In Ada95 I guess the "at clause" has been replaced with the 'Address.
I'm trying to port a piece of software from Ada83 to Ada95, and the "at
clause" is being handled differently by the GNAT compiler. In case 1 it
ignores it (I'm not sure if it will work, as I do not have the complete
software compiled), and in case 2 it complains. Is there any way to get
around this problem.
CASE 1:
-------
The complier does not complain about the following code.
for TWO_INT_REC_TYPE use
--% Bit-rep for 64-bit computations
record at mod 8;
INT1 at 0 range 0..31;
--% Bit-rep for first integer of 64-bit computation
INT2 at 4 range 0..31;
--% Bit-rep for second integer of 64-bit computation
end record;
function case_one(X : in SYSTEM.ADDRESS;
Y : in SYSTEM.ADDRESS) return BOOLEAN is
X_REC : TWO_INT_REC_TYPE;
for X_REC use at X;
begin
....
....
end case_one;
CASE 2:
------
procedure case_two(
ITEM : in SYSTEM.ADDRESS;
ITEM_COUNT : POSITIVE := 1 ) is
ITEM_ADDRESS : SYSTEM.ADDRESS := ITEM;
begin
-- LOOP through each item to be byte swapped
for COUNT in 1 .. ITEM_COUNT
loop
-- Perform the byte swap operation
SWAP:
declare
OLD_VALUE : EIGHT_BYTES_TYPE;
NEW_VALUE : EIGHT_BYTES_TYPE;
-- tried the the following two ways. Both ways are not accepted by the
compiler, and do not work.
for NEW_VALUE use at ITEM_ADDRESS;
for NEW_VALUE'ADDRESS use ITEM_ADDRESS;
begin
.....
.....
end;
Please respond directly to my email address (ramesh@eagle.bgm.link.com),
any help/ideas appreciated.
Thanks,
Ramesh
