Proof step 63 from proof sharing-pathex-field-self (previous step)

st[refs0 .last -- _type] .type = mkclasstype(class), validrefs(`docs2store', st[refs0 .last -- fs '] .refval ' + refs0, mkclasstype(`java.lang.Object' .class), st), fs ' ∈ instfields(class) ⊦ refs0 = [], refs0 .last = jvmref, hasSharing(refs0 .last, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 62:
st[refs0 .last -- fs '] = refval(r) ∧ is_referencevalue(st[refs0 .last -- fs ']), st[refs0 .last -- _type] .type = mkclasstype(class), validrefs(`docs2store', r ' + refs0, mkclasstype(`java.lang.Object' .class), st), fs ' ∈ instfields(class) ⊦ refs0 = [], refs0 .last = jvmref, hasSharing(refs0 .last, st)
