Proof step 2 from proof ushort-inj (previous step)

us2i(sho) = us2i(sho0) ⊦ sho = sho0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ s2i(sho) < 0 → us2i(sho) = 2 ^ 16 + s2i(sho)
Proof step 4:
¬ s2i(sho) < 0, us2i(sho) = us2i(sho0) ⊦ sho = sho0
Proof step 13:
s2i(sho) < 0, 2 ^ 16 + s2i(sho) = us2i(sho0) ⊦ sho = sho0

Rule argument

name: ushort-neg rotate: F subst: [sho] → [sho]
