Proof step 1 from proof intshiftrsign-rec-neg (conclusion)

⊦ i < 0 ∧ 0 < j ∧ j < 32 → i i>> j = (i - 1) / 2 i>> (j - 1)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
j < 32, i < 0, 0 < j ⊦ i i>> j = (i - 1) / 2 i>> (j - 1)

Rule argument

Additional information

Used simplifier rules: ⊦ j < i ∧ i ≤ 0 → j < 0; (forward)% ⊦ i < j ∧ 0 ≤ i → 0 < j; (forward)% ⊦ i < j ∧ 0 < i → 0 < j ∧ 1 < j; (forward)
