Proof step 13 from proof junkref-put-refval-01 (previous step)

is_arraytype(st[r0 -- _type] .type), mkarraytype(ty) ≤ st[r0 -- _type] .type, junkrefs(str, r ' + refs0, st[r -- _type] .type, st[r0 -- i ', refval(r1)]), st[r1 -- _type] .type ≤ ty ⊦ r0 = jvmref, r1 = jvmref, junkref(str, r, st), junkref(str, r1, st), mkarraytype(st[r1 -- _type] .type) ≤ st[r0 -- _type] .type

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 12:
st[r1 -- _type] = typeval(ty0) ∧ is_typevalue(st[r1 -- _type]), is_arraytype(st[r0 -- _type] .type), mkarraytype(ty) ≤ st[r0 -- _type] .type, junkrefs(str, r ' + refs0, st[r -- _type] .type, st[r0 -- i ', refval(r1)]), ty0 ≤ ty ⊦ r0 = jvmref, r1 = jvmref, junkref(str, r, st), junkref(str, r1, st), mkarraytype(ty0) ≤ st[r0 -- _type] .type
