--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.  The problem is:
typedef int64_t int64x1_t;
typedef int32_t int32x1_t;
typedef int16_t int16x1_t;
typedef int8_t int8x1_t;
typedef double float64x1_t;
typedef uint64_t uint64x1_t;
typedef uint32_t uint32x1_t;
typedef uint16_t uint16x1_t;
typedef uint8_t uint8x1_t;

Those all should add __attribute__((vector_size(sizeof(type) )) to them to make
them a vector of one element.
