PR29092 fix causes a regression:
/* { dg-do compile } */
/* { dg-options "-O2 -ftree-vectorize" } */
typedef struct __attribute__ ((aligned (8)))
{
short a, b, c, d;
} A;
typedef struct
{
A a[24];
} B;
static const A b = { 0, 0, 1, -1 };
void
foo (B *x)
{
int i;
for (i = 0; i <= 20; i += 4)
x->a[i] = b;
}
results in endless recursion in make_vector_type. The RECORD_TYPE type has
attributes, but as any record type TYPE_MAIN_VARIANT of it is itself.
