Proof step 7 from proof update-index-one (
previous step
)
⊦ ri[key ' + [], adr + []] = ri[key, adr]
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 8
:
⊦ adr + ax = adr ' + ax
Proof step 9
:
⊦ ri[key ' + [], adr ' + []] = ri[key, adr]
Rule argument
spec: list, inst: address-list-set name: c seq: ⊦ adr + ax = adr ' + ax subst: [ax, adr] → [[], adr] flags: <all paths>
