Proof step 22 from proof sharing-twopaths (previous step)

st[r -- sks0] = refval(refs0 .last), st[r -- sks] = refval(r0), # sks1 = # refs0, st[r0 -- sks1] .refval = refs0 .last, fits(r, sks0, st), fits(r, sks, st), validrefs(str, r0 ' + refs0, mkclasstype(`java.lang.Object' .class), st), fits(r0, sks1, st) ⊦ refs0 = [], r = jvmref, sks = sks0, sks = [], sks0 = [], r0 = jvmref, refs0 .last = jvmref, sks ⊑ sks0, hasSharing(r, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 21:
st[r0 -- sks1] = refval(r1) ∧ is_referencevalue(st[r0 -- sks1]), st[r -- sks0] = refval(refs0 .last), st[r -- sks] = refval(r0), # sks1 = # refs0, r1 = refs0 .last, fits(r, sks0, st), fits(r, sks, st), validrefs(str, r0 ' + refs0, mkclasstype(`java.lang.Object' .class), st), fits(r0, sks1, st) ⊦ refs0 = [], r = jvmref, sks = sks0, sks = [], sks0 = [], r0 = jvmref, refs0 .last = jvmref, sks ⊑ sks0, hasSharing(r, st)
