Proof step 11 from proof junkrefs-primarray (previous step)

refs = r0 + refs0, r0 = st[r -- i '] .refval, st[r -- _type] .type = mkarraytype(ty0), is_referencevalue(st[r -- i ']), i < st[r -- _length] .intval, r ∈ st, 0 < st[r -- _length] .intval, 0 ≤ i, ty0 ≤ ty, is_primtype(ty), is_array(str, r, st), okarray(r, ty, st), junkrefs(str, refs, ty0, st) ⊦ refs = [], r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
st[r -- _type] .type = mkarraytype(ty0), is_referencevalue(st[r -- i ']), i < st[r -- _length] .intval, r ∈ st, 0 < st[r -- _length] .intval, 0 ≤ i, ty0 ≤ ty, is_primtype(ty), is_array(str, r, st), okarray(r, ty, st), junkrefs(str, st[r -- i '] .refval ' + refs0, ty0, st) ⊦ r = jvmref
