Proof step 5 from proof bint-carry-01 (previous step)

⊦ ¬ (band(4294967295, i) + band(4294967295, j)) l>>> 32 < ~2147483648

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
(band(4294967295, i) + band(4294967295, j)) l>>> 32 < ~2147483648, (band(4294967295, i) + band(4294967295, j)) l>>> 32 < 0 ⊦

Rule argument

Additional information

Used simplifier rules: ⊦ i < (* j) ∧ j < 0 → i < 0; (forward)
