17 /* This was compiled from a trivial program just to test the
18 DW_OP_stack_value and DW_OP_implicit_value operators:
20 unsigned int func (unsigned int arg) __attribute__ ((__noinline__));
22 unsigned int func (unsigned int arg)
24 unsigned int uses_stack_op = 23;
25 unsigned int uses_lit_op = 0x7fffffff;
26 unsigned int result = arg;
29 result += uses_lit_op + uses_stack_op;
35 result -= uses_stack_op + uses_lit_op;
38 return result * uses_stack_op; // line 19, see the .exp file
41 int main (int argc, char *argv[])
46 Then it was compiled with:
48 gcc -fvar-tracking{,-assignments} -gdwarf-3
49 -fno-inline{,-functions,-small-functions,-functions-called-once}
