Proof step 31 from proof exactarray-copy-01 (previous step)

st[r -- _type] .type = mkarraytype(byte_type), r -- _length ∈ st, is_integervalue(st[r -- _length]), is_arrayref(r, st[r -- _length] .intval, st), exactarray(r0, byte_type, st), i + j ≤ st[r0 -- _length] .intval, r0 ∈ st, 0 ≤ i, 0 ≤ j, r -- _type ∈ st, is_typevalue(st[r -- _type]), 0 ≤ st[r -- _length] .intval, r ∈ st ⊦ r0 = jvmref, r = jvmref, is_arrayref(r, st[r -- _length] .intval, arraycopy(r0, i, r, i0, j, st))

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 30:
st[r -- _length] = intval(i1), st[r -- _type] .type = mkarraytype(byte_type), r -- _length ∈ st, is_integervalue(st[r -- _length]), is_arrayref(r, i1, st), exactarray(r0, byte_type, st), i + j ≤ st[r0 -- _length] .intval, r0 ∈ st, 0 ≤ i, 0 ≤ j, r -- _type ∈ st, is_typevalue(st[r -- _type]), 0 ≤ i1, r ∈ st ⊦ r0 = jvmref, r = jvmref, is_arrayref(r, i1, arraycopy(r0, i, r, i0, j, st))
