Proof step 4 from proof exactref-put-01 (previous step)

rk = r0 -- sk, r ∈ st, r ≠ jvmref → r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ st[r -- _type] .type = ty ⊦ r0 = r, exactreftype(refval(r), ty, st[rk, val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
r ∈ st, r ≠ jvmref → r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ st[r -- _type] .type = ty ⊦ r0 = r, exactreftype(refval(r), ty, st[r0 -- sk, val])
