Proof step 7 from proof exactarray-length-01 (previous step)

st[r -- _type] = typeval(ty0), ty0 = mkarraytype(ty), st[r -- _length] = intval(st[r -- _length] .intval), r -- _type ∈ st, is_typevalue(st[r -- _type]), r -- _length ∈ st, is_arrayref(r, st[r -- _length] .intval, st), r ∈ st ⊦ val2int(st[r -- _length]) = st[r -- _length] .intval, r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
st[r -- _length] = intval(st[r -- _length] .intval), st[r -- _type] = typeval(mkarraytype(ty)), r ∈ st, is_arrayref(r, st[r -- _length] .intval, st), r -- _length ∈ st, r -- _type ∈ st ⊦ r = jvmref, val2int(st[r -- _length]) = st[r -- _length] .intval
