Hi:
I have changed the code as you said, but it is more error now.
1 #include
2
3 int main()
4 {
5 char src[30] = {"This is a test message.\n"};
6 char dst[30];
7 int len = 25;
8
9 __asm_

You need to specify that the registers are clobbered by the asm.
The only
way to do that is to use output constrai

You need to specify that the registers are clobbered by the asm. The only
way to do that is to use output constraints ("+D", "+c", etc.) on proper
temporaries.
int lent = len;
char *dstt = dst;
char *srct = s
