Proof step 27 from proof junkrefs-addobj (previous step)

st[r -- i '] = refval(r2), junkrefs(str, r2 ' + refs, st[r -- _type] .type .type, addobj(r0, class, fis, st)), i < st[r -- _length] .intval, is_array(str, r, st), st[r -- _type] .type ≤ ty, is_array(str, r, addobj(r0, class, fis, st)), newref(r0, st), 0 < st[r -- _length] .intval, 0 ≤ i, ∀ str0, ty0, r1, class0, fis0, st0. junkrefs(str0, r2 ' + refs, ty0, addobj(r1, class0, fis0, st0)) ∧ newref(r1, st0) → r1 = jvmref ∨ junkrefs(str0, r2 ' + refs, ty0, st0) ⊦ r0 = jvmref, r = jvmref, r = r0, junkrefs(str, r ' + r2 ' + refs, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

[crewrite-arg: junkrefs-array , F , [st, ty, refs, r, str] → [st, ty, r2 ' + refs, r, str] ]
