Proof step 8 from proof exactarray-06 (previous step)

st[r -- _type] .type = mkarraytype(int_type), st[r -- _length] = intval(i), 0 ≤ i, r ∈ st, is_arrayref(r, i, st), r -- _length ∈ st, is_typevalue(st[r -- _type]), r -- _type ∈ st ⊦ r = jvmref, r = r0, exactreftype(refval(r), mkarraytype(int_type), st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
st[r -- _type] = typeval(ty), ty = mkarraytype(int_type), st[r -- _length] = intval(i), 0 ≤ i, r ∈ st, is_arrayref(r, i, st), r -- _length ∈ st, is_typevalue(st[r -- _type]), r -- _type ∈ st ⊦ r = jvmref, r = r0, exactreftype(refval(r), mkarraytype(int_type), st)

Rule argument
