The op1 value is loaded from the stack frame at -0xcc. The
frame value appears to be set here:
0x00317e48 <find_simple_exit+5540>: stw r19,-cc(sp)
Breakpoint 3, 0x00317e48 in iv_number_of_iterations (loop=0x40296580,
desc=0x9b62d8) at ../../gcc/gcc/loop-iv.c:2605
2605 bound = GEN_INT (((unsigned HOST_WIDEST_INT) 1 << (size - 1 ) <<
1) - 1);
(gdb) p/x $r19
$10 = 0x0
(gdb) p size
$11 = 31
