------- Comment #1 from rguenth at gcc dot gnu dot org 2010-02-19 11:08 ------- Likely because of the union in
__extension__ static __inline void __attribute__ ((__always_inline__))
vst4_u8 (uint8_t * __a, uint8x8x4_t __b)
{
union { uint8x8x4_t __i; __builtin_neon_oi __o; } __bu = { __b };
__builtin_neon_vst4v8qi ((__builtin_neon_qi *) __a, __bu.__o);
}
which does copy-initialization of __bu. Also try GCC 4.5.
