Proof step 11 from proof is_array-byte-noref (previous step)

st[r -- _type] = typeval(ty), ty = mkarraytype(byte_type), st[r -- i '] = refval(r1), is_typevalue(st[r -- _type]), r -- _type ∈ st, 0 < st[r -- _length] .intval, 0 ≤ i, r ∈ st, i < st[r -- _length] .intval, okarray(r, byte_type, st) ⊦ r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
st[r -- i '] = refval(r1), st[r -- _type] = typeval(mkarraytype(byte_type)), okarray(r, byte_type, st), i < st[r -- _length] .intval, r ∈ st, 0 ≤ i, 0 < st[r -- _length] .intval, r -- _type ∈ st ⊦ r = jvmref

Rule argument
