Hi Jiang,
I'm sorry that I've taken so long to get to this, I've been out of office
for several weeks. I have one comment.

For vmul_n_* intrinsics, is there a reason we don't want to use the
GCC vector extension syntax to allow us to write these as:
__extension__ static __inline float32x2_t __attribute__ ((__always_inline__))
vmul_n_f32 (float32x2_t __a, float32_t __b)
{
return __a * __b;
}
It would be great if we could make that work.
Thanks,
James
