Proof step 13 from proof okstore-03 (previous step)

_type ≠ sk, is_typevalue(st[r -- _type]), _out ∈ st, _mode ∈ st, r0 = r ∨ r0 ∈ st, ∀ r. r ≠ jvmref ∧ r ∈ st → r -- _type ∈ st ∧ is_typevalue(st[r -- _type]), r -- _type ∈ st ∨ _type = sk ⊦ r0 = jvmref, r = jvmref, r0 -- _type ∈ st, r0 = r ∧ _type = sk

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 12:
is_typevalue(st[r -- _type]), _out ∈ st, _mode ∈ st, r0 ∈ st, r -- _type ∈ st, r ∈ st, ∀ r. r ≠ jvmref ∧ r ∈ st → r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ⊦ r0 = jvmref, r = jvmref, _type = sk, r0 = r, r0 -- _type ∈ st
