Proof step 16 from proof okarray-put-07 (previous step)

st[r0 -- _length] = intval(i), 0 ≤ i, r0 -- _type ∈ st, is_typevalue(st[r0 -- _type]), is_arraytype(st[r0 -- _type] .type), st[r0 -- _type] .type .type ≤ ty, r0 -- _length ∈ st, is_arrayref(r0, i, st), r0 ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r0 -- j '], ty) ⊦ r0 = jvmref, r = r0, okarray(refval(r0), ty, i, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 15:
st[r0 -- _type] .type = mkarraytype(ty0), st[r0 -- _length] = intval(i), 0 ≤ i, r0 -- _type ∈ st, is_typevalue(st[r0 -- _type]), is_arraytype(st[r0 -- _type] .type), ty0 ≤ ty, r0 -- _length ∈ st, is_arrayref(r0, i, st), r0 ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r0 -- j '], ty) ⊦ r0 = jvmref, r = r0, okarray(refval(r0), ty, i, st)
