Proof step 39 from proof validref-primarray (conclusion)

⊦ is_primtype(ty) → (validref(str, r, mkarraytype(ty), st) ↔ r = jvmref ∨ okarray(r, ty, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ validref(str, r, mkarraytype(ty), st) ∧ r ≠ jvmref → okarray(r, ty, st)
Proof step 2:
⊦ validref(str, jvmref, ty, st)
Proof step 38:
is_primtype(ty), okarray(r, ty, st), r ∈ st ⊦ r = jvmref, validref(str, r, mkarraytype(ty), st)

Rule argument
