Proof step 10 from proof validref-newref-subset (previous step)

newref(r, st0), validref(str, r, mkarraytype(byte_type), st), st ⊆ st0 ⊦ r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ newref(r, st) → ¬ validref(str, r, ty, st)
Proof step 9:
¬ newref(r, st), newref(r, st0), validref(str, r, mkarraytype(byte_type), st), st ⊆ st0 ⊦ r = jvmref

Rule argument

[crewrite-arg: validref-newref , F , [st, ty, r, str] → [st, mkarraytype(byte_type), r, str] ]
