Proof step 28 from proof div-inshort (previous step)

0 < s2i(sho0) / s2i(sho1), 32767 < s2i(sho0) / s2i(sho1) ⊦ s2i(sho1) = ~1, s2i(sho1) = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 29:
⊦ ¬ i0 < i ∧ 0 ≤ i ∧ 0 < j → ¬ i0 < i / j
Proof step 30:
¬(¬ 32767 < s2i(sho0) ∧ 0 ≤ s2i(sho0) ∧ 0 < s2i(sho1)), 0 < s2i(sho0) / s2i(sho1), 32767 < s2i(sho0) / s2i(sho1) ⊦ s2i(sho1) = ~1, s2i(sho1) = 0

Rule argument

spec: int-div inst: name: div-nls seq: ⊦ ¬ i0 < i ∧ 0 ≤ i ∧ 0 < j → ¬ i0 < i / j subst: [j, i, i0] → [s2i(sho1), s2i(sho0), 32767] flags: rewrite
