Proof step 10 from proof add-putbar-rew (previous step)

⊦ (addobj(r0, class, fis, st)[r0 -- fs ']) = (addobj(r0, class, fis, putByteArray(bytes, r, i, st))[r0 -- fs ']), r = r0, fs ' ∈ fis

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
⊦ ¬ sk ∈ fis ∧ sk ≠ _type → (addobj(r, class, fis, st)[r -- sk]) = st[r -- sk]
Proof step 8:
¬ _type ∈ fis ⊦ (addobj(r, class1, fis, st)[r -- _type]) = typeval(mkclasstype(class1))
Proof step 9:
⊦ ¬ sk ∈ fis ∧ sk ≠ _type → (addobj(r, class, fis, st)[r -- sk]) = st[r -- sk]

Rule argument

[crewrite-arg: add-notin , F , [sk, st, fis, class, r] → [fs ', st, fis, class, r0] ]
