# RANGE [irange] int [0, 63] MASK 0x3f VALUE 0x0
_6 = __builtin_clrsbllD.2056 (-9178289175401163344(OVF));
>From sccp:
final value replacement:
_82 = PHI <_3(23)>
with expr: -9178289175401163344(OVF)
final stmt:
_82 = -9178289175401163344(OVF);
The bug is (OVF) is there ...
That is it is not getting folded afterwards and internal-fn.cc has:
```
if (TREE_CODE (arg) == INTEGER_CST)
{
tree ret = fold_const_call (as_combined_fn (fn), TREE_TYPE (arg), arg);
gcc_checking_assert (ret && TREE_CODE (ret) == INTEGER_CST);
expand_assignment (lhs, ret, false);
return false;
}
```
