Proof step 14 from proof ushort-inj (previous step)

s2i(sho) + 65536 = us2i(sho0), s2i(sho) < 0 ⊦ sho = sho0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 15:
⊦ s2i(sho) < 0 → us2i(sho) = 2 ^ 16 + s2i(sho)
Proof step 16:
¬ s2i(sho0) < 0, s2i(sho) + 65536 = us2i(sho0), s2i(sho) < 0 ⊦ sho = sho0

Rule argument

name: ushort-neg rotate: F subst: [sho] → [sho0]

Additional information

Used simplifier rules: short-equal: ⊦ s2i(shoi) = s2i(shoj) ↔ shoi = shoj;% ⊦ i + j = i + i0 ↔ j = i0;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i; Used terms: sho0
