Proof step 14 from proof stsub-copy (previous step)

st[r -- sk] = st0[r -- sk], newref(r0, st), r -- sk ∈ st, r -- sk ∈ st0, r ∈ st, r ∈ st0, ∀ rk. rk ∈ st → rk ∈ st0 ∧ st[rk] = st0[rk] ⊦ r0 = jvmref, r -- sk ∈ arraycopy(r1, i, r0, i0, j, st0) ∧ st0[r -- sk] = (arraycopy(r1, i, r0, i0, j, st0)[r -- sk])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 12:
⊦ r1 ≠ r0 → (arraycopy(r, i, r0, i0, j, st)[r1 -- sk]) = st[r1 -- sk]
Proof step 13:
⊦ r1 ≠ r0 → (r1 -- sk ∈ arraycopy(r, i, r0, i0, j, st) ↔ r1 -- sk ∈ st)

Rule argument

[crewrite-arg: copy-at , F , [sk, r1, st, j, i0, r0, i, r] → [sk, r, st0, j, i0, r0, i, r1] ]
