Proof step 12 from proof disjoint-pathex-forward (previous step)

disjoint(str, r ' + r0 ', st), path∃(str, r, r1, st), path∃(str, r1, r2, st), path∃(str, r0, r2, st) ⊦ r0 = r1, r2 = jvmref, r = r0

User applied rule insert lemma

And obtained the following new goals

Rule argument

[x0lemmaarg: spec-name: instance-name: lemma-name: disjoint-nopathex antecedent: succedent: disjoint(str, r ' + r0 ', st) ∧ path∃(str, r, r1, st) ∧ r ≠ r0 ∧ r1 ≠ jvmref → ¬ path∃(str, r0, r1, st) substlist: [str, r, r0, st, r1] → [str, r, r0, st, r2] add preconditions?: F is rewrite lemma?: F current spec?: T rotate lemma?: F replace all?: F paths: () dummy: () ]
