Sorry, I misunderstood you. The function is a part of a large project (namely,
u-boot-1.1.3).
What about this:
//--------------
char str1[]="123456789";
char str2[10];
int
main()
{
register volatile char* cptr asm ("r29");
cptr=str1;
asm volatile ("or 29,29,29"); //optimization barrier, supposedly
memcpy(str2,cptr,10);
return (int)cptr; //just for fun
}
//-----------
Compile with -ffixed-r29.
