Proof step 4 from proof validval-field-shortval (previous step)

¬ is_referencevalue(shortval(sho)) ⊦ okval(shortval(sho), mkfs(class, ty, fieldvar) .type) ∧ mkfs(class, ty, fieldvar) ' ≠ _length ↔ ty = short_type

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
okval(shortval(sho), ty) ⊦ ty = short_type, mkfs(class, ty, fieldvar) ' = _length

Rule argument
