Subject: Representation item appears too late

Message-ID: <87640vgvvl.fsf@ludovic-brenta.org> (raw)
Consider the following declarations:
package A is
type Size is (Small, Large);
type Foo is range 1 .. 8;
type T is record
A : Boolean;
B : Boolean;
C : Boolean;
D : Size_Type;
E : Foo;
end record;
procedure P (X : in T); -- a null procedure for the sake of example
end A;
with A;
package B is
type T is new A.T;
for T use record -- line 5
A at 0 range 0 .. 0;
B at 0 range 1 .. 1;
C at 0 range 2 .. 2;
D at 0 range 3 .. 3;
E at 0 range 4 .. 7;
end record;
end B;
Compiling B with GCC 4.1 I get:
gcc-4.1 -c -g -O2 -gnatafnoy -gnatVa -gnatwa -I- -gnatA /home/lbrenta/src/ada/b.ads
b.ads:5:04: representation item appears too late
b.ads:5:04: primitive operations already defined for "T"
gnatmake: "/home/lbrenta/src/ada/b.ads" compilation error
This also happens with GCC 4.2.
Of course, removing procedure A.P also removes the error but this is
not an option.
What should I do to specify a representation clause? Do I have to
resort to declaring a mirror type in B? Why?
Thanks for any advice.
