Proof step 7 from proof validval-field-shortval (conclusion)

⊦ validval(str, r -- fs ', shortval(sho), st) ↔ fs .type = short_type

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 6:
fs = mkfs(class, ty, fieldvar) ⊦ validval(str, r -- fs ', shortval(sho), st) ↔ ty = short_type

Rule argument

[speclemmaarg: , class = fs .class ∧ ty = fs .type ∧ fieldvar = fs .field ↔ fs = mkfs(class, ty, fieldvar) ,[fs, class, ty, fieldvar] → [fs, class, ty, fieldvar] ,T ,fieldspec , ,elim ]
