Proof step 6 from proof isarray-put-01 (previous step)

⊦ r = r0, is_array(r0, st[r -- sk, val]) ↔ is_array(r0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ 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 5:
⊦ r = r0, r0 ≠ jvmref ∧ r0 -- _type ∈ st[r -- sk, val] ∧ is_typevalue(st[r -- sk, val][r0 -- _type]) ∧ is_arraytype((st[r -- sk, val][r0 -- _type]) .type) ∧ okarray(r0, (st[r -- sk, val][r0 -- _type]) .type .type, st[r -- sk, val]) ↔ is_array(r0, st)

Rule argument

[crewrite-arg: is-any-array, F, [st, r] → [st[r -- sk, val], r0]]
