Proof step 6 from proof copy-ref (previous step)

⊦ r1 = r0, reftypep(refval(r1), arraycopy(r, i, r0, i0, j, st)) ↔ reftypep(refval(r1), st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ reftypep(val, st) ↔ is_referencevalue(val) ∧ (val .refval = jvmref ∨ val .refval ∈ st)
Proof step 5:
⊦ r1 = r0, is_referencevalue(refval(r1)) ∧ (refval(r1) .refval = jvmref ∨ refval(r1) .refval ∈ arraycopy(r, i, r0, i0, j, st)) ↔ reftypep(refval(r1), st)

Rule argument

[speclemmaarg: , reftypep(val, st) ↔ is_referencevalue(val) ∧ (val .refval = jvmref ∨ val .refval ∈ st) ,[st, val] → [arraycopy(r, i, r0, i0, j, st), refval(r1)] ,F ,storefunsx , ,reftypep ]
