Proof step 16 from proof getintarray-subset (previous step)

User applied rule insert rewrite lemma

And obtained the following new goals

• Proof step 3:

  ⊦ 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 15:

  r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_arraytype(st[r -- _type] .type) ∧ okarray(r, st[r -- _type] .type .type, st), st ⊆ st0, r -- _length ∈ st, r ∈ st ⊦ getintarray(r, st) = getintarray(r, st0), is_arrayref(r, st[r -- _length] .intval, st)
