Proof step 1 from proof longshiftzero-zero-03 (conclusion)

⊦ 0 ≤ i → (i l>>> j = 0 ↔ i / 2 ^ band(j, 63) = 0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
0 ≤ i ⊦ i l>>> j = 0 ↔ i / 2 ^ band(j, 63) = 0

Rule argument

Additional information

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