+        // Don't make assumptions about the high bits.
+        ConstantAsMetadata::get(ConstantInt::get(I32Ty, 0xffffffff))
+      };
----------------
Range is [a, b). I.e. upper bound is not included in the range. But range can wrap around so 0 should work.
At the same time you will need to check that lower bound is not zero then because it is required that a != b.
