// { dg-do compile { target c++11 } } // // There were two related problems here, depending on the vintage. At // one time: // // typedef struct A { ... } A [[gnu::aligned (16)]]; // // would cause original_types to go into an infinite loop. At other // times, the attributes applied to an explicit typedef would be lost // (check_b3 would have a negative size). // First check that the declaration is accepted and has an effect. typedef struct A { int i; } A [[gnu::aligned (16)]]; int check_A[alignof (A) >= 16 ? 1 : -1]; // Check that the alignment is only applied to the typedef. struct B { int i; }; struct B b1; typedef struct B B [[gnu::aligned (16)]]; struct B b2; B b3; int check_b1[__alignof__ (b1) == __alignof__ (b2) ? 1 : -1]; int check_b3[__alignof__ (b3) >= 16 ? 1 : -1];
