Confirmed.
D.1711_3 = D.1710_2 & 2256872798;
which is likely CONSTANT
Lattice value changed to CONSTANT Lattice value changed to CONSTANT
0x00000000000000000 (0x0000000008685255e). Adding SSA edges to worklist.
The problem is obvious, 0x0000000008685255e should have its sign bit extended
to all the way to the end.
