Proof step 8 from proof comp-copy (previous step)

j1 < j, i + j ≤ j0, 0 ≤ i, 0 ≤ j, 0 ≤ j1, 0 < j ⊦ (arraycopy(r0, 0, r, 0, j0, st)[r0 -- (i + j1) ']) = (arraycopy(r0, 0, r, 0, j0, st)[r -- (i + j1) '])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ r1 ≠ r0 → (arraycopy(r, i, r0, i0, j, st)[r1 -- sk]) = st[r1 -- sk]
Proof step 7:
r0 ≠ r, j1 < j, i + j ≤ j0, 0 ≤ i, 0 ≤ j, 0 ≤ j1, 0 < j ⊦ st[r0 -- (i + j1) '] = (arraycopy(r0, 0, r, 0, j0, st)[r -- (i + j1) '])

Rule argument

[crewrite-arg: copy-at , F , [sk, r1, st, j, i0, r0, i, r] → [(i + j1) ', r0, st, j0, 0, r, 0, r0] ]
