Proof step 10 from proof validstatfields-addobj (previous step)

newref(r, st), validstatfields(str, sk ' + sks0, st), ∀ str, st, r, class, fis. validstatfields(str, sks0, st) ∧ newref(r, st) → r = jvmref ∨ validstatfields(str, sks0, addobj(r, class, fis, st)) ⊦ r = jvmref, validstatfields(str, sk ' + sks0, addobj(r, class, fis, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ validstatfields(str, sk ' + sks, st) ↔ validstatfield(str, sk, st) ∧ validstatfields(str, sks, st)
Proof step 9:
newref(r, st), validstatfields(str, sk ' + sks0, st), ∀ str, st, r, class, fis. validstatfields(str, sks0, st) ∧ newref(r, st) → r = jvmref ∨ validstatfields(str, sks0, addobj(r, class, fis, st)) ⊦ r = jvmref, validstatfield(str, sk, addobj(r, class, fis, st)) ∧ validstatfields(str, sks0, addobj(r, class, fis, st))

Rule argument

[crewrite-arg: validstatfields-rec , F , [st, sks, sk, str] → [addobj(r, class, fis, st), sks0, sk, str] ]
