Proof step 12 from proof validrefs-primarray (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 11:
st[r -- _type] .type = mkarraytype(ty), st[r -- i '] = refval(r0), validrefs(str, r0 ' + refs, ty, st), r ∈ st, 0 ≤ i, 0 < st[r -- _length] .intval, is_primtype(ty), is_array(str, r, st), okarray(r, ty, st), i < st[r -- _length] .intval ⊦ r ' + r0 ' + refs = jvmref ', r = jvmref, is_reftype(ty)
