--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Before phiopt, we have:
if (func_14_uli_8.0_1 != 0)
goto <bb 3>; [50.00%]
else
goto <bb 4>; [50.00%]
<bb 3> [local count: 805306369]:
_11 = pretmp_13 & 5;
goto <bb 5>; [100.00%]
<bb 4> [local count: 536870913]:
if (pretmp_13 != 0)
goto <bb 3>; [50.00%]
else
goto <bb 5>; [50.00%]
<bb 5> [local count: 1073741824]:
# prephitmp_12 = PHI <_11(3), 0(4)>
There must be a missing check (In reply to Andrew Pinski from comment #1)

It actually worked at that point. r12-5301-g045206450386bcd77 did cause some IR
changes but I do think this just exposed a bug in r12-5300.
