Proof step 5 from proof isarray-bytearray (previous step)

st[r -- _type] .type = mkarraytype(byte_type), is_array(r, st) ⊦ r = jvmref, okarray(r, byte_type, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ is_array(r, st) ↔ r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_arraytype(st[r -- _type] .type) ∧ okarray(r, st[r -- _type] .type .type, st)
Proof step 3:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 4:
⊦ okarray(r, byte_type, st) → st[r -- _type] .type = mkarraytype(byte_type)

Rule argument

[crewrite-arg: is-any-array, F, [st, r] → [st, r]]
