Proof step 1 from proof short-range (conclusion)

⊦ ~32768 ≤ s2i(sho) ∧ s2i(sho) ≤ 32767

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
s2i(sho) < ~32768, s2i(sho) < 0 ⊦

Rule argument

Additional information

Used simplifier rules: short-ngr: ⊦ ¬ 32767 < s2i(sho);% ⊦ i < (* j) ∧ j < 0 → i < 0; (forward)% ⊦ ¬ i ≤ j ↔ j < i;
