-- { dg-do compile } package Size_Clause2 is -- The alignment of the record is capped to the greatest power of 2 -- factor of the size, so that the real size is 40 too and the size -- of a component of type R1 in a packed record can be 40. type R1 is record I : Integer; B : aliased Boolean; end record; for R1'Size use 40; type S1 is record rr : R1; -- size must be 40 end record; pragma Pack(S1); -- The record is explicitly given alignment 1 so its real type is 40 too. -- The size of a component of type R2 in a packed record is naturally 40. type R2 is record I : Integer; B : aliased Boolean; end record; for R2'Size use 40; for R2'Alignment use 1; type S2 is record rr : R2; -- size must be 40 end record; pragma Pack(S2); -- The record is explicitly given alignment 4 so its real type is 64. -- That's not OK, because the size of a component of type R3 in a packed -- record cannot be 40 so the size clause is violated. type R3 is record I : Integer; B : aliased Boolean; end record; for R3'Size use 40; -- { dg-error "size for .R3. too small" } for R3'Alignment use 4; type S3 is record rr : R3; -- size must be 40 end record; pragma Pack(S3); end Size_Clause2;
