/* This was compiled from a trivial program just to test the
   DW_OP_stack_value and DW_OP_implicit_value operators:

    unsigned int func (unsigned int arg) __attribute__ ((__noinline__));

    unsigned int func (unsigned int arg)
    {
      unsigned int uses_stack_op = 23;
      unsigned int uses_lit_op = 0x7fffffff;
      unsigned int result = arg;

      if (arg % 2)
	result += uses_lit_op + uses_stack_op;
      else
	{
	  ++uses_stack_op;
	  ++uses_lit_op;

	  result -= uses_stack_op + uses_lit_op;
	}

      return result * uses_stack_op;  // line 19, see the .exp file
    }

    int main (int argc, char *argv[])
    {
      return func (1024);
    }

  Then it was compiled with:
	
	gcc -fvar-tracking{,-assignments} -gdwarf-3
	-fno-inline{,-functions,-small-functions,-functions-called-once}
	-O2
