Proof step 7 from proof unchanged-validref (previous step)

unchanged(str, r, st, st1), st[r -- _type] .type ≤ ty ⊦ r = jvmref, st1[r -- _type] .type ≤ ty, junkref(str, r, st)

User applied rule insert rewrite lemma

Rule argument

[x0lemmaarg: spec-name: instance-name: lemma-name: unchanged-type-01 antecedent: succedent: unchanged(str, r, st, st1) ∧ is_valid_ref(str, r, st) ∧ r ≠ jvmref → st1[r -- _type] = st[r -- _type] substlist: [str, r, st, st1] → [str, r, st, st1] add preconditions?: F is rewrite lemma?: T current spec?: T rotate lemma?: F replace all?: T paths: ((1, 0, 1, 1, 0)) dummy: () ]
