Proof step 20 from proof short-neq-01 (previous step)

~32768 ≤ s2i(sho), 65536 * i + s2i(sho) = 0, 0 < i, s2i(sho) ≤ 0, s2i(sho) < i ⊦ i = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 21:
⊦ i + j = 0 ↔ j = ~ i
Proof step 22:
~32768 ≤ s2i(sho), s2i(sho) = ~(65536 * i), 0 < i, s2i(sho) ≤ 0, s2i(sho) < i ⊦ i = 0

Rule argument

seq: ⊦ i + j = 0 ↔ j = ~ i subst: [j, i] → [s2i(sho), 65536 * i] rotate: F spec: int-abs inst: name: rew-eqzero-01
