I modified the source as below.
It seems that It does not work.
I am not sure whether it is a bug.Or gcc can not treat this situation?
// copy 128 bit one time
#define burst_copy(dst,src,len) {\
__asm__ __vola

You're updating the source and destination register but marking them only as
input in the asm. That's invalid. You trick GCC into believing that as it
hasn't changed, it can re-use the register with the source-address.
