Proof step 1 from proof shiftright-shift (conclusion)

⊦ 0 ≤ j ∧ 0 ≤ j0 ∧ j + j0 < 32 → (i >> j) >> j0 = i >> (j + j0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
j + j0 < 32, 0 ≤ j, 0 ≤ j0 ⊦ (i >> j) >> j0 = i >> (j + j0)

Rule argument

Additional information

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