While trying:
```
Optimizing block #19
1>>> STMT 1 = _102 ne_expr 0
1>>> STMT 0 = _102 eq_expr 0
Optimizing statement _109 = a_lsm.19_24 + 11;
LKUP STMT _109 = a_lsm.19_24 plus_expr 11
2>>> STMT _109 = a_lsm.19_24 plus_expr 11
Optimizing statement if (_108 != 0)
```
The IR in this area is:
```
# RANGE [irange] int [-2147483647, +INF]
_109 = a_lsm.19_24 + 11;
if (_108 != 0)
```
Where a_lsm.19_24 is defined by:
```
# _15 = PHI <_17(D)(4), _16(7)>
# a_lsm.19_24 = PHI <a_lsm.19_30(4), a_lsm.19_14(7)>
# a_lsm_flag.20_27 = PHI <0(4), a_lsm_flag.20_26(7)>
# b_lsm_flag.22_29 = PHI <0(4), 1(7)>
```
_14 is defined by:
# a_lsm.19_14 = PHI <_8(6), _8(5), a_lsm.19_24(25)>
While _30 is defined by:
a_lsm.19_30 = aD.2750;
_8 is defined by:
# _8 = PHI <_13(24), _39(9), _53(10), _61(11), _67(12), _73(13), _79(14),
_85(15), _91(16), _97(17), _103(18), _109(19), _115(20), _121(21), _127(22),
_133(23)>
Which is +1, +2, etc.
nothing shocking for an unrolled loop.
