Proof step 20 from proof exactarray-put-02 (previous step)

exactarray(refval(r), byte_type, st[r -- _length] .intval, st) ⊦ r = jvmref, is_arrayref(r, st[r -- _length] .intval, st[r0 -- j ', byteval(by)]) ∧ st[r -- _length] = intval(st[r -- _length] .intval) ∧ r -- _length ∈ st ∧ exactreftype(refval(r), mkarraytype(byte_type), st[r0 -- j ', byteval(by)])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ exactarray(val, ty, i, st) ↔ exactreftype(val, mkarraytype(ty), st) ∧ val .refval ≠ jvmref ∧ (val .refval -- _length) × intval(i) ∈ st ∧ is_arrayref(val .refval, i, st)
Proof step 19:
exactreftype(refval(r), mkarraytype(byte_type), st) ∧ refval(r) .refval ≠ jvmref ∧ (refval(r) .refval -- _length) × intval(st[r -- _length] .intval) ∈ st ∧ is_arrayref(refval(r) .refval, st[r -- _length] .intval, st) ⊦ r = jvmref, is_arrayref(r, st[r -- _length] .intval, st[r0 -- j ', byteval(by)]) ∧ st[r -- _length] = intval(st[r -- _length] .intval) ∧ r -- _length ∈ st ∧ exactreftype(refval(r), mkarraytype(byte_type), st[r0 -- j ', byteval(by)])
