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__ __volatile__ ( \
"1: \n\t" \
"ldmia %1!,{r3-r6} \n\t" \
"stmia %0!,{r3-r6} \n\t" \
"subs %2, %2, #1 \n\t" \
"bne 1b \n\t" \
::"r"(dst),"r"(src),"r"(len) \
:"%0", "%1" , "%2","r3","r4","r5","r6" ); \
}
