Proof step 4 from proof shiftright-shift (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
i < 0, 0 ≤ j0, 0 ≤ j, j + j0 < 32 ⊦ (i >> j) >> j0 = i >> (j + j0)

Rule argument

Additional information

Used simplifier rules: ⊦ i < 0 ∧ 0 ≤ j → i < j;% ⊦ j < i ∧ i ≤ 0 → j < 0; (forward)% ⊦ i < j ∧ j ≤ j0 → i < j0; (forward)% ⊦ i + j = j + i;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ 0 ≤ i ∧ 0 ≤ j → ¬ i + j < 0;% ⊦ ¬ i ≤ j ↔ j < i;
