/* This was compiled from a trivial program just to test the

   DW_OP_stack_value and DW_OP_implicit_value operators:

21
    unsigned int func (unsigned int arg) __attribute__ ((__noinline__));
22
 
23
    unsigned int func (unsigned int arg)
24
    {

26
      unsigned int uses_lit_op = 0x7fffffff;
27
      unsigned int result = arg;
28
 
29
      if (arg % 2)
30
        result += uses_lit_op + uses_stack_op;
