Proof step 12 from proof copy-same-01-01 (previous step)

r2 ∈ st0, 0 < i3, 0 ≤ i, 0 ≤ i2, exactarray(r2, int_type, st0), i < i3, i2 + i3 ≤ st0[r2 -- _length] .intval ⊦ r2 = jvmref, r1 = r2, (r2 -- i0 ' ∈ arraycopy(r1, i1, r2, i2, i3, st0[r2 -- (i2 + i) ', val]) ↔ r2 -- i0 ' ∈ arraycopy(r1, i1, r2, i2, i3, st0)) ∧ (arraycopy(r1, i1, r2, i2, i3, st0[r2 -- (i2 + i) ', val])[r2 -- i0 ']) = (arraycopy(r1, i1, r2, i2, i3, st0)[r2 -- i0 '])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ r ≠ r0 ∧ i0 ≤ j0 ∧ j0 < i0 + j → (arraycopy(r, i, r0, i0, j, st)[r0 -- j0 ']) = st[r -- ((j0 - i0) + i) ']
Proof step 11:
¬ (r1 ≠ r2 ∧ i2 ≤ i0 ∧ i0 < i2 + i3), r2 ∈ st0, 0 < i3, 0 ≤ i, 0 ≤ i2, exactarray(r2, int_type, st0), i < i3, i2 + i3 ≤ st0[r2 -- _length] .intval ⊦ r2 = jvmref, r1 = r2, (r2 -- i0 ' ∈ arraycopy(r1, i1, r2, i2, i3, st0[r2 -- (i2 + i) ', val]) ↔ r2 -- i0 ' ∈ arraycopy(r1, i1, r2, i2, i3, st0)) ∧ (arraycopy(r1, i1, r2, i2, i3, st0[r2 -- (i2 + i) ', val])[r2 -- i0 ']) = (arraycopy(r1, i1, r2, i2, i3, st0)[r2 -- i0 '])
