Proof step 5 from proof is_obj-putba (previous step)

⊦ r = r1, is_obj(r, class, sk ', putByteArray(bytes, r1, i, st)) ↔ is_obj(r, class, sk ', st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ is_obj(r, class1, sks, st) ↔ r ≠ jvmref ∧ (r -- _type) × typeval(mkclasstype(class1)) ∈ st ∧ goodfieldsandtypes(r, sks, st)
Proof step 4:
⊦ r = r1, r ≠ jvmref ∧ (r -- _type) × typeval(mkclasstype(class)) ∈ putByteArray(bytes, r1, i, st) ∧ goodfieldsandtypes(r, sk ', putByteArray(bytes, r1, i, st)) ↔ is_obj(r, class, sk ', st)

Rule argument

[crewrite-arg: is_obj , F , [st, sks, class1, r] → [putByteArray(bytes, r1, i, st), sk ', class, r] ]
