Proof step 121 from proof junkrefs-put-nopathexplus-equiv (previous step)

junkrefs(str, r ' + refs0, ty, st), ∀ val, sk, r0, st, ty, r, str, refs. # refs < # refs0 → (junkrefs(str, r ' + refs, ty, st) → junkrefs(str, r ' + refs, ty, st[r0 -- sk, val]) ∨ sk = _type ∨ path∃+(str, r, r0, st)) ⊦ sk = _type, path∃+(str, r, r0, st), junkrefs(str, r ' + refs0, ty, st[r0 -- sk, val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ r = jvmref → ¬ junkrefs(str, r ' + refs, ty, st)
Proof step 120:
r ≠ jvmref, junkrefs(str, r ' + refs0, ty, st), ∀ val, sk, r0, st, ty, r, str, refs. # refs < # refs0 → (junkrefs(str, r ' + refs, ty, st) → junkrefs(str, r ' + refs, ty, st[r0 -- sk, val]) ∨ sk = _type ∨ path∃+(str, r, r0, st)) ⊦ sk = _type, path∃+(str, r, r0, st), junkrefs(str, r ' + refs0, ty, st[r0 -- sk, val])
