 Hi,
 
 not quite sure what's going on, but the problem is still there in gcc
 version 3.4 20030203. Here's a smaller testcase:
 
 extern inline void copy_tofrom_user(long len)
 {
     register long pv asm("$27") = 0;
     register long cu_from asm("$7") = 0;
     asm volatile ("" : "=r"(len), "=r"(cu_from), "=r"(pv)
 		     : "0"(len), "1"(cu_from), "2"(pv));
 }
 
 static void stli_memread(int *brdp) {    
     copy_tofrom_user(1 % *brdp);
 }
 
 Looks like some conflict between the divmod pattern and the $27 asm.
